O The O MET4 B-GENE gene O was O cloned O , O and O its O sequence O reveals O that O it O encodes O a O protein O related O to O the O family O of O the O bZIP B-GENE transcriptional I-GENE activators I-GENE .

O RESULTS O : O At O the O initiation O of O dialysis O PD O patients O were O approximately O 6 O years O younger O ( O P O < O 0 O . O 0001 O ) O than O HD O patients O . O The O utility O of O such O analyses O in O the O design O of O ceramic O / O substrate O bilayer O systems O for O optimal O resistance O to O lifetime O - O threatening O damage O is O discussed O .

O 22 B-Chemical - I-Chemical oxacalcitriol I-Chemical suppresses O secondary B-Disease hyperparathyroidism I-Disease without O inducing O low B-Disease bone I-Disease turnover I-Disease in O dogs O with O renal B-Disease failure I-Disease . O BACKGROUND O : O Calcitriol B-Chemical therapy O suppresses O serum O levels O of O parathyroid O hormone O ( O PTH O ) O in O patients O with O renal B-Disease failure I-Disease but O has O several O drawbacks O , O including O hypercalcemia B-Disease and O / O or O marked O suppression B-Disease of I-Disease bone I-Disease turnover I-Disease , O which O may O lead O to O adynamic B-Disease bone I-Disease disease I-Disease . O A O new O vitamin B-Chemical D I-Chemical analogue O , O 22 B-Chemical - I-Chemical oxacalcitriol I-Chemical ( O OCT B-Chemical ) O , O has O been O shown O to O have O promising O characteristics O . O This O study O was O undertaken O to O determine O the O effects O of O OCT B-Chemical on O serum O PTH O levels O and O bone O turnover O in O states O of O normal O or O impaired B-Disease renal I-Disease function I-Disease . O METHODS O : O Sixty O dogs O were O either O nephrectomized O ( O Nx O , O N O = O 38 O ) O or O sham O - O operated O ( O Sham O , O N O = O 22 O ) O . O The O animals O received O supplemental O phosphate B-Chemical to O enhance O PTH O secretion O . O Fourteen O weeks O after O the O start O of O phosphate B-Chemical supplementation O , O half O of O the O Nx O and O Sham O dogs O received O doses O of O OCT B-Chemical ( O three O times O per O week O ) O ; O the O other O half O were O given O vehicle O for O 60 O weeks O . O Thereafter O , O the O treatment O modalities O for O a O subset O of O animals O were O crossed O over O for O an O additional O eight O months O . O Biochemical O and O hormonal O indices O of O calcium B-Chemical and O bone O metabolism O were O measured O throughout O the O study O , O and O bone O biopsies O were O done O at O baseline O , O 60 O weeks O after O OCT B-Chemical or O vehicle O treatment O , O and O at O the O end O of O the O crossover O period O . O RESULTS O : O In O Nx O dogs O , O OCT B-Chemical significantly O decreased O serum O PTH O levels O soon O after O the O induction O of O renal B-Disease insufficiency I-Disease . O In O long O - O standing O secondary B-Disease hyperparathyroidism I-Disease , O OCT B-Chemical ( O 0 O . O 03 O microg O / O kg O ) O stabilized O serum O PTH O levels O during O the O first O months O . O Serum O PTH O levels O rose O thereafter O , O but O the O rise O was O less O pronounced O compared O with O baseline O than O the O rise O seen O in O Nx O control O . O These O effects O were O accompanied O by O episodes O of O hypercalcemia B-Disease and O hyperphosphatemia B-Disease . O In O animals O with O normal O renal O function O , O OCT B-Chemical induced O a O transient O decrease O in O serum O PTH O levels O at O a O dose O of O 0 O . O 1 O microg O / O kg O , O which O was O not O sustained O with O lowering O of O the O doses O . O In O Nx O dogs O , O OCT B-Chemical reversed O abnormal O bone O formation O , O such O as O woven B-Disease osteoid I-Disease and O fibrosis B-Disease , O but O did O not O significantly O alter O the O level O of O bone O turnover O . O In O addition O , O OCT B-Chemical improved O mineralization O lag O time O , O ( O that O is O , O the O rate O at O which O osteoid O mineralizes O ) O in O both O Nx O and O Sham O dogs O . O CONCLUSIONS O : O These O results O indicate O that O even O though O OCT B-Chemical does O not O completely O prevent O the O occurrence O of O hypercalcemia B-Disease in O experimental O dogs O with O renal B-Disease insufficiency I-Disease , O it O may O be O of O use O in O the O management O of O secondary B-Disease hyperparathyroidism I-Disease because O it O does O not O induce O low B-Disease bone I-Disease turnover I-Disease and O , O therefore O , O does O not O increase O the O risk O of O adynamic B-Disease bone I-Disease disease I-Disease . O Hypotension B-Disease , O bradycardia B-Disease , O and O asystole B-Disease after O high O - O dose O intravenous O methylprednisolone B-Chemical in O a O monitored O patient O . O We O report O a O case O of O hypotension B-Disease , O bradycardia B-Disease , O and O asystole B-Disease after O intravenous O administration O of O high O - O dose O methylprednisolone B-Chemical in O a O 73 O - O year O - O old O patient O who O underwent O electrocardiographic O ( O ECG O ) O monitoring O throughout O the O episode O . O There O was O a O history O of O ischemic B-Disease cardiac B-Disease disease I-Disease 9 O years O earlier O . O The O patient O was O admitted O with O a O pulmonary B-Disease - I-Disease renal I-Disease syndrome I-Disease with O hemoptysis B-Disease , O rapidly O progressive O renal B-Disease failure I-Disease , O and O hypoxemia B-Disease that O required O mechanical O ventilation O in O the O intensive O care O unit O . O After O receiving O advanced O cardiopulmonary O resuscitation O , O the O patient O recovered O cardiac O rhythm O . O The O ECG O showed O a O junctional O rhythm O without O ventricular B-Disease arrhythmia I-Disease . O This O study O reviews O the O current O proposed O mechanisms O of O sudden B-Disease death I-Disease after O a O high O dose O of O intravenous O methylprednisolone B-Chemical ( O IVMP B-Chemical ) O . O These O mechanisms O are O not O well O understood O because O , O in O most O cases O , O the O patients O were O not O monitored O at O the O moment O of O the O event O . O Rapid O infusion O and O underlying O cardiac B-Disease disease I-Disease were O important O risk O factors O in O the O case O reported O here O , O and O the O authors O discount O ventricular B-Disease arrhythmia I-Disease as O the O main O mechanism O . O Worsening O of O levodopa B-Chemical - O induced O dyskinesias B-Disease by O motor O and O mental O tasks O . O Ten O patients O who O had O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease with O disabling O dyskinesia B-Disease were O included O in O this O study O to O evaluate O the O role O of O mental O ( O mental O calculation O ) O and O motor O ( O flexion O / O extension O of O right O fingers O , O flexion O / O extension O of O left O fingers O , O flexion O / O extension O of O the O neck O , O speaking O aloud O ) O tasks O on O the O worsening O of O peak O - O dose O dyskinesia B-Disease following O administration O of O an O effective O single O dose O of O apomorphine B-Chemical . O Compared O with O the O score O at O rest O ( O 1 O . O 3 O + O / O - O 0 O . O 3 O ) O , O a O significant O aggravation O of O the O dyskinesia B-Disease score O was O observed O during O speaking O aloud O ( O 5 O . O 2 O + O / O - O 1 O . O 1 O , O p O < O 0 O . O 05 O ) O , O movements O of O right O ( O 4 O . O 5 O + O / O - O 1 O . O 0 O , O p O < O 0 O . O 05 O ) O and O left O ( O 3 O . O 7 O + O / O - O 0 O . O 8 O , O p O < O 0 O . O 05 O ) O fingers O , O movements O of O the O neck O ( O 5 O . O 1 O + O / O - O 1 O . O 0 O , O p O < O 0 O . O 05 O ) O , O and O mental O calculation O ( O 3 O . O 1 O + O / O - O 1 O . O 0 O , O p O < O 0 O . O 05 O ) O . O These O results O suggest O that O activation O tasks O such O as O " O speaking O aloud O " O could O be O used O for O objective O assessment O of O dyskinesia B-Disease severity O . O Urine O N O - O acetyl O - O beta O - O D O - O glucosaminidase O - O - O a O marker O of O tubular O damage O ? O BACKGROUND O : O Although O an O indicator O of O renal B-Disease tubular I-Disease dysfunction I-Disease , O an O increased O urinary O N O - O acetyl O - O beta O - O D O - O glucosaminidase O ( O NAG O ) O activity O might O reflect O increased O lysosomal O activity O in O renal O tubular O cells O . O METHODS O : O Puromycin B-Chemical aminonucleoside I-Chemical ( O PAN B-Chemical ) O was O administered O to O Sprague O Dawley O rats O to O induce O proteinuria B-Disease . O Total O protein O , O albumin O , O NAG O activity O and O protein O electrophoretic O pattern O were O assessed O in O daily O urine O samples O for O 33 O days O . O The O morphological O appearance O of O the O kidneys O was O examined O on O days O three O , O four O , O six O , O eight O and O thirty O three O and O the O NAG O isoenzyme O patterns O on O days O zero O , O four O , O eight O and O thirty O three O . O RESULTS O : O Following O intravenous O PAN B-Chemical urine O volume O and O urine O NAG O activity O increased O significantly O by O day O two O , O but O returned O to O normal O by O day O four O . O After O day O four O all O treated O animals O exhibited O a O marked O rise O in O urine O albumin O , O total O protein O excretion O and O NAG O activity O . O Electrophoresis O showed O a O generalised O increase O in O middle O and O high O molecular O weight O urine O proteins O from O day O four O onwards O . O Protein O droplets O first O appeared O prominent O in O tubular O cells O on O day O four O . O Peak O urine O NAG O activity O and O a O change O in O NAG O isoenzyme O pattern O coincided O with O both O the O peak O proteinuria B-Disease and O the O reduction O in O intracellular O protein O and O NAG O droplets O ( O day O six O onwards O ) O . O CONCLUSIONS O : O This O animal O model O demonstrates O that O an O increase O in O lysosomal O turnover O and O hence O urine O NAG O activity O , O occurs O when O increased O protein O is O presented O to O the O tubular O cells O . O Urine O NAG O activity O is O thus O a O measure O of O altered O function O in O the O renal O tubules O and O not O simply O an O indicator O of O damage O . O Cauda B-Disease equina I-Disease syndrome I-Disease after O spinal O anaesthesia O with O hyperbaric O 5 O % O lignocaine B-Chemical : O a O review O of O six O cases O of O cauda B-Disease equina I-Disease syndrome I-Disease reported O to O the O Swedish O Pharmaceutical O Insurance O 1993 O - O 1997 O . O Six O cases O of O cauda B-Disease equina I-Disease syndrome I-Disease with O varying O severity O were O reported O to O the O Swedish O Pharmaceutical O Insurance O during O the O period O 1993 O - O 1997 O . O All O were O associated O with O spinal O anaesthesia O using O hyperbaric O 5 O % O lignocaine B-Chemical . O Five O cases O had O single O - O shot O spinal O anaesthesia O and O one O had O a O repeat O spinal O anaesthetic O due O to O inadequate O block O . O The O dose O of O hyperbaric O 5 O % O lignocaine B-Chemical administered O ranged O from O 60 O to O 120 O mg O . O Three O of O the O cases O were O most O likely O caused O by O direct O neurotoxicity B-Disease of O hyperbaric O 5 O % O lignocaine B-Chemical . O In O the O other O 3 O cases O , O direct O neurotoxicity B-Disease was O also O probable O , O but O unfortunately O radiological O investigations O were O not O done O to O definitely O exclude O a O compressive O aetiology O . O All O cases O sustained O permanent O neurological B-Disease deficits I-Disease . O We O recommend O that O hyperbaric O lignocaine B-Chemical should O be O administered O in O concentrations O not O greater O than O 2 O % O and O at O a O total O dose O preferably O not O exceeding O 60 O mg O . O Systemic O toxicity B-Disease following O administration O of O sirolimus B-Chemical ( O formerly O rapamycin B-Chemical ) O for O psoriasis B-Disease : O association O of O capillary B-Disease leak I-Disease syndrome I-Disease with O apoptosis O of O lesional O lymphocytes O . O BACKGROUND O : O Sirolimus B-Chemical ( O formerly O rapamycin B-Chemical ) O is O an O immunosuppressive O agent O that O interferes O with O T O - O cell O activation O . O After O 2 O individuals O with O psoriasis B-Disease developed O a O capillary B-Disease leak I-Disease syndrome I-Disease following O treatment O with O oral O sirolimus B-Chemical lesional O skin O cells O and O activated O peripheral O blood O cells O were O analyzed O for O induction O of O apoptosis O . O OBSERVATIONS O : O A O keratome O skin O specimen O from O 1 O patient O with O sirolimus B-Chemical - O induced O capillary B-Disease leak I-Disease syndrome I-Disease had O a O 2 O . O 3 O - O fold O increase O in O percentage O of O apoptotic O cells O ( O to O 48 O % O ) O compared O with O an O unaffected O sirolimus B-Chemical - O treated O patient O with O psoriasis B-Disease ( O 21 O % O ) O . O Activated O peripheral O blood O T O cells O from O patients O with O psoriasis B-Disease tended O to O exhibit O greater O spontaneous O or O dexamethasone B-Chemical - O induced O apoptosis O than O did O normal O T O cells O , O particularly O in O the O presence O of O sirolimus B-Chemical . O CONCLUSIONS O : O Severe O adverse O effects O of O sirolimus B-Chemical include O fever B-Disease , O anemia B-Disease , O and O capillary B-Disease leak I-Disease syndrome I-Disease . O These O symptoms O may O be O the O result O of O drug O - O induced O apoptosis O of O lesional O leukocytes O , O especially O activated O T O lymphocytes O , O and O possibly O release O of O inflammatory O mediators O . O Because O patients O with O severe O psoriasis B-Disease may O develop O capillary B-Disease leak I-Disease from O various O systemic O therapies O , O clinical O monitoring O is O advisable O for O patients O with O inflammatory B-Disease diseases I-Disease who O are O treated O with O immune O modulators O . O Effect O of O lithium B-Chemical maintenance O therapy O on O thyroid O and O parathyroid O function O . O OBJECTIVES O : O To O assess O changes O induced O by O lithium B-Chemical maintenance O therapy O on O the O incidence O of O thyroid O , O parathyroid O and O ion O alterations O . O These O were O evaluated O with O respect O to O the O duration O of O lithium B-Chemical therapy O , O age O , O sex O , O and O family O history O ( O whether O or O not O the O patient O had O a O first O - O degree O relative O with O thyroid B-Disease disease I-Disease ) O . O DESIGN O : O Prospective O study O . O SETTING O : O Affective O Disorders O Clinic O at O St O . O Mary O ' O s O Hospital O , O Montreal O . O PATIENTS O : O One O hundred O and O one O patients O ( O 28 O men O and O 73 O women O ) O with O bipolar B-Disease disorder I-Disease receiving O lithium B-Chemical maintenance O therapy O ranging O from O 1 O year O ' O s O to O 32 O years O ' O duration O . O The O control O group O consisted O of O 82 O patients O with O no O psychiatric B-Disease or O endocrinological O diagnoses O from O the O hospital O ' O s O out O - O patient O clinics O . O OUTCOME O MEASURES O : O Laboratory O analyses O of O calcium B-Chemical , O magnesium B-Chemical and O thyroid O - O stimulating O hormone O levels O performed O before O beginning O lithium B-Chemical therapy O and O at O biannual O follow O - O up O . O RESULTS O : O Hypothyroidism B-Disease developed O in O 40 O patients O , O excluding O 8 O patients O who O were O hypothyroid B-Disease at O baseline O . O All O patients O having O first O - O degree O relatives O affected O by O thyroid B-Disease illness I-Disease had O accelerated O onset O of O hypothyroidism B-Disease ( O 3 O . O 7 O years O after O onset O of O lithium B-Chemical therapy O ) O compared O with O patients O without O a O family O history O ( O 8 O . O 6 O years O after O onset O of O lithium B-Chemical therapy O ) O . O Women O over O 60 O years O of O age O were O more O often O affected O by O hypothyroidism B-Disease than O women O under O 60 O years O of O age O ( O 34 O . O 6 O % O versus O 31 O . O 9 O % O ) O . O Magnesium B-Chemical levels O in O patients O on O lithium B-Chemical treatment O were O unchanged O from O baseline O levels O . O After O lithium B-Chemical treatment O , O calcium B-Chemical levels O were O higher O than O either O baseline O levels O or O control O levels O . O Thus O , O lithium B-Chemical treatment O counteracted O the O decrease O in O plasma O calcium B-Chemical levels O associated O with O aging O . O CONCLUSIONS O : O Familial O thyroid B-Disease illness I-Disease is O a O risk O factor O for O hypothyroidism B-Disease and O hypercalcemia B-Disease during O lithium B-Chemical therapy O . O Severe O immune O hemolytic B-Disease anemia I-Disease associated O with O prophylactic O use O of O cefotetan B-Chemical in O obstetric O and O gynecologic O procedures O . O Second O - O and O third O - O generation O cephalosporins B-Chemical , O especially O cefotetan B-Chemical , O are O increasingly O associated O with O severe O , O sometimes O fatal O immune O hemolytic B-Disease anemia I-Disease . O We O noticed O that O 10 O of O our O 35 O cases O of O cefotetan B-Chemical - O induced O hemolytic B-Disease anemias I-Disease were O in O patients O who O had O received O cefotetan B-Chemical prophylactically O for O obstetric O and O gynecologic O procedures O . O Eight O of O these O cases O of O severe O immune O hemolytic B-Disease anemia I-Disease are O described O . O Effects O of O nonsteroidal O anti O - O inflammatory O drugs O on O hemostasis O in O patients O with O aneurysmal B-Disease subarachnoid I-Disease hemorrhage I-Disease . O Platelet O function O is O impaired O by O nonsteroidal O anti O - O inflammatory O drugs O ( O NSAIDs O ) O with O prominent O anti O - O inflammatory O properties O . O Their O safety O in O patients O undergoing O intracranial O surgery O is O under O debate O . O Patients O with O aneurysmal B-Disease subarachnoid I-Disease hemorrhage I-Disease ( O SAH B-Disease ) O were O randomized O to O receive O either O ketoprofen B-Chemical , O 100 O mg O , O three O times O a O day O ( O ketoprofen B-Chemical group O , O n O = O 9 O ) O or O a O weak O NSAID O , O acetaminophen B-Chemical , O 1 O g O , O three O times O a O day O ( O acetaminophen B-Chemical group O , O n O = O 9 O ) O starting O immediately O after O the O diagnosis O of O aneurysmal B-Disease SAH B-Disease . O Treatment O was O continued O for O 3 O days O postoperatively O . O Test O blood O samples O were O taken O before O treatment O and O surgery O as O well O as O on O the O first O , O third O , O and O fifth O postoperative O mornings O . O Maximal O platelet B-Disease aggregation I-Disease induced O by O 6 O microM O of O adenosine B-Chemical diphosphate I-Chemical decreased O after O administration O of O ketoprofen B-Chemical . O Aggregation O was O lower O ( O P O < O . O 05 O ) O in O the O ketoprofen B-Chemical group O than O in O the O acetaminophen B-Chemical group O just O before O surgery O and O on O the O third O postoperative O day O . O In O contrast O , O maximal O platelet B-Disease aggregation I-Disease increased O in O the O acetaminophen B-Chemical group O on O the O third O postoperative O day O as O compared O with O the O pretreatment O platelet B-Disease aggregation I-Disease results O ( O P O < O . O 05 O ) O . O One O patient O in O the O ketoprofen B-Chemical group O developed O a O postoperative O intracranial O hematoma B-Disease . O Coagulation O ( O prothrombin O time O [ O PT O ] O , O activated O partial O thromboplastin O time O [ O APPT O ] O , O fibrinogen O concentration O , O and O antithrombin O III O [ O AT O III O ] O ) O was O comparable O between O the O two O groups O . O Ketoprofen B-Chemical but O not O acetaminophen B-Chemical impaired O platelet O function O in O patients O with O SAH B-Disease . O If O ketoprofen B-Chemical is O used O before O surgery O on O cerebral O artery B-Disease aneurysms I-Disease , O it O may O pose O an O additional O risk O factor O for O hemorrhage B-Disease . O Nitric B-Chemical oxide I-Chemical synthase O expression O in O the O course O of O lead B-Chemical - O induced O hypertension B-Disease . O We O recently O showed O elevated O reactive O oxygen B-Chemical species O ( O ROS O ) O , O reduced O urinary O excretion O of O NO B-Chemical metabolites O ( O NOx O ) O , O and O increased O NO B-Chemical sequestration O as O nitrotyrosine B-Chemical in O various O tissues O in O rats O with O lead B-Chemical - O induced O hypertension B-Disease . O This O study O was O designed O to O discern O whether O the O reduction O in O urinary O NOx O in O lead B-Chemical - O induced O hypertension B-Disease is O , O in O part O , O due O to O depressed O NO B-Chemical synthase O ( O NOS O ) O expression O . O Male O Sprague O - O Dawley O rats O were O randomly O assigned O to O a O lead B-Chemical - O treated O group O ( O given O lead B-Chemical acetate I-Chemical , O 100 O ppm O , O in O drinking O water O and O regular O rat O chow O ) O , O a O group O given O lead B-Chemical and O vitamin B-Chemical E I-Chemical - O fortified O chow O , O or O a O normal O control O group O given O either O regular O food O and O water O or O vitamin B-Chemical E I-Chemical - O fortified O food O for O 12 O weeks O . O Tail O blood O pressure O , O urinary O NOx O excretion O , O plasma O malondialdehyde B-Chemical ( O MDA B-Chemical ) O , O and O endothelial O and O inducible O NOS O ( O eNOS O and O iNOS O ) O isotypes O in O the O aorta O and O kidney O were O measured O . O The O lead B-Chemical - O treated O group O exhibited O a O rise O in O blood O pressure O and O plasma O MDA B-Chemical concentration O , O a O fall O in O urinary O NOx O excretion O , O and O a O paradoxical O rise O in O vascular O and O renal O tissue O eNOS O and O iNOS O expression O . O Vitamin B-Chemical E I-Chemical supplementation O ameliorated O hypertension B-Disease , O lowered O plasma O MDA B-Chemical concentration O , O and O raised O urinary O NOx O excretion O while O significantly O lowering O vascular O , O but O not O renal O , O tissue O eNOS O and O iNOS O expression O . O Vitamin B-Chemical E I-Chemical supplementation O had O no O effect O on O either O blood O pressure O , O plasma O MDA B-Chemical , O or O NOS O expression O in O the O control O group O . O The O study O also O revealed O significant O inhibition O of O NOS O enzymatic O activity O by O lead B-Chemical in O cell O - O free O preparations O . O In O conclusion O , O lead B-Chemical - O induced O hypertension B-Disease in O this O model O was O associated O with O a O compensatory O upregulation O of O renal O and O vascular O eNOS O and O iNOS O expression O . O This O is O , O in O part O , O due O to O ROS O - O mediated O NO B-Chemical inactivation O , O lead B-Chemical - O associated O inhibition O of O NOS O activity O , O and O perhaps O stimulatory O actions O of O increased O shear O stress O associated O with O hypertension B-Disease . O Glyceryl B-Chemical trinitrate I-Chemical induces O attacks O of O migraine B-Disease without I-Disease aura I-Disease in O sufferers O of O migraine B-Disease with I-Disease aura I-Disease . O Migraine B-Disease with I-Disease aura I-Disease and O migraine B-Disease without I-Disease aura I-Disease have O the O same O pain B-Disease phase O , O thus O indicating O that O migraine B-Disease with I-Disease aura I-Disease and O migraine B-Disease without I-Disease aura I-Disease share O a O common O pathway O of O nociception O . O In O recent O years O , O increasing O evidence O has O suggested O that O the O messenger O molecule O nitric B-Chemical oxide I-Chemical ( O NO B-Chemical ) O is O involved O in O pain B-Disease mechanisms O of O migraine B-Disease without I-Disease aura I-Disease . O In O order O to O clarify O whether O the O same O is O true O for O migraine B-Disease with I-Disease aura I-Disease , O in O the O present O study O we O examined O the O headache B-Disease response O to O intravenous O infusion O of O glyceryl B-Chemical trinitrate I-Chemical ( O GTN B-Chemical ) O ( O 0 O . O 5 O microg O / O kg O / O min O for O 20 O min O ) O in O 12 O sufferers O of O migraine B-Disease with I-Disease aura I-Disease . O The O specific O aim O was O to O elucidate O whether O an O aura O and O / O or O an O attack O of O migraine B-Disease without I-Disease aura I-Disease could O be O induced O . O Fourteen O healthy O subjects O served O as O controls O . O Aura O symptoms O were O not O elicited O in O any O subject O . O Headache B-Disease was O more O severe O in O migraineurs B-Disease than O in O the O controls O during O and O immediately O after O GTN B-Chemical infusion O ( O p O = O 0 O . O 037 O ) O as O well O as O during O the O following O 11 O h O ( O p O = O 0 O . O 008 O ) O . O In O the O controls O , O the O GTN B-Chemical - O induced O headache B-Disease gradually O disappeared O , O whereas O in O migraineurs B-Disease peak O headache B-Disease intensity O occurred O at O a O mean O time O of O 240 O min O post O - O infusion O . O At O this O time O the O induced O headache B-Disease in O 6 O of O 12 O migraineurs B-Disease fulfilled O the O diagnostic O criteria O for O migraine B-Disease without I-Disease aura I-Disease of O the O International O Headache B-Disease Society O . O The O results O therefore O suggest O that O NO B-Chemical is O involved O in O the O pain B-Disease mechanisms O of O migraine B-Disease with I-Disease aura I-Disease . O Since O cortical O spreading O depression B-Disease has O been O shown O to O liberate O NO B-Chemical in O animals O , O this O finding O may O help O our O understanding O of O the O coupling O between O cortical O spreading O depression B-Disease and O headache B-Disease in O migraine B-Disease with I-Disease aura I-Disease . O Rapid O reversal O of O life O - O threatening O diltiazem B-Chemical - O induced O tetany B-Disease with O calcium B-Chemical chloride I-Chemical . O We O describe O a O patient O who O developed O tetany B-Disease with O sudden O respiratory B-Disease arrest I-Disease after O the O infusion O of O intravenous O diltiazem B-Chemical .

O Little O information O is O available O to O predict O which O patients O are O at O highest O risk O for O this O complication O . O OBJECTIVE O : O To O quantify O specific O clinical O predictors O of O reduction B-Disease in I-Disease renal I-Disease function I-Disease in O patients O with O CHF B-Disease who O are O prescribed O angiotensin B-Chemical - O converting O enzyme O inhibitor O therapy O . O METHOD O : O We O analyzed O data O from O the O Studies O of O Left B-Disease Ventricular I-Disease Dysfunction I-Disease ( O SOLVD O ) O , O a O randomized O , O double O - O blind O , O placebo O - O controlled O trial O of O enalapril B-Chemical for O the O treatment O of O CHF B-Disease . O There O were O 3379 O patients O randomly O assigned O to O enalapril B-Chemical with O a O median O follow O - O up O of O 974 O days O and O 3379 O patients O randomly O assigned O to O placebo O with O a O mean O follow O - O up O of O 967 O days O .

O Treatment O of O tacrolimus B-Chemical - O related O adverse O effects O by O conversion O to O cyclosporine B-Chemical in O liver O transplant O recipients O . O When O tacrolimus B-Chemical side O effects O persist O despite O dose O reduction O , O conversion O to O cyclosporine B-Chemical - O based O immunosuppression O ( O CyA O ) O is O necessary O .

O When O tacrolimus B-Chemical side O effects O are O unresponsive O to O dose O reduction O , O conversion O to O CyA O can O be O accomplished O safely O , O with O no O increased O risk O of O rejection O and O excellent O long O - O term O outcome O . O Ocular O manifestations O of O juvenile B-Disease rheumatoid I-Disease arthritis I-Disease . O We O followed O 210 O cases O of O juvenile B-Disease rheumatoid I-Disease arthritis I-Disease closely O for O eleven O years O . O Thirty O - O six O of O the O 210 O patients O ( O 17 O . O 2 O % O ) O developed O iridocyclitis B-Disease . O Iridocyclitis B-Disease was O seen O most O frequently O in O young O female O patients O ( O 0 O to O 4 O years O ) O with O the O monoarticular O or O pauciatricular O form O of O the O arthritis B-Disease . O However O , O 30 O % O of O the O patients O developed O uveitis B-Disease after O 16 O years O of O age O . O Although O 61 O % O of O patients O had O a O noncontributory O ocular O history O on O entry O , O 42 O % O had O active O uveitis B-Disease on O entry O . O Our O approach O was O effective O in O detecting O uveitis B-Disease in O new O cases O and O exacerbations O of O uveitis B-Disease in O established O cases O . O Forty O - O four O percent O of O patients O with O uveitis B-Disease had O one O or O more O identifiable O signs O or O symptoms O , O such O as O red O eye O , O ocular B-Disease pain I-Disease , O decreased B-Disease visual I-Disease acuity I-Disease , O or O photophobia B-Disease , O in O order O of O decreasing O frequency O . O Even O after O early O detection O and O prompt O treatment O , O 41 O % O of O cases O of O uveitis B-Disease did O not O respond O to O more O than O six O months O of O intensive O topical O treatment O with O corticosteroids B-Chemical and O mydriatics O . O Despite O this O , O there O was O a O dramatic O decrease O in O the O 50 O % O incidence O of O blinding O complications O of O uveitis B-Disease cited O in O earlier O studies O . O Cataract B-Disease and O band B-Disease keratopathy I-Disease occurred O in O only O 22 O and O 13 O % O of O our O group O , O respectively O . O We O used O chloroquine B-Chemical or O hydroxychloroquine B-Chemical in O 173 O of O 210 O cases O and O found O only O one O case O of O chorioretinopathy B-Disease attributable O to O these O drugs O . O Systemically O administered O corticosteroids B-Chemical were O used O in O 75 O of O 210 O cases O ; O a O significant O number O of O posterior O subcapsular O cataracts B-Disease was O found O . O Typical O keratoconjunctivitis B-Disease sicca O developed O in O three O of O the O uveitis B-Disease cases O . O This O association O with O uveitis B-Disease and O JRA O was O not O noted O previously O .

O Cyclophosphamide B-Chemical - O induced O cystitis B-Disease in O freely O - O moving O conscious O rats O : O behavioral O approach O to O a O new O model O of O visceral B-Disease pain I-Disease . O PURPOSE O : O To O develop O a O model O of O visceral B-Disease pain I-Disease in O rats O using O a O behavioral O approach O . O Cyclophosphamide B-Chemical ( O CP B-Chemical ) O , O an O antitumoral O agent O known O to O produce O toxic O effects O on O the O bladder O wall O through O its O main O toxic O metabolite O acrolein B-Chemical , O was O used O to O induce O cystitis B-Disease . O MATERIALS O AND O METHODS O : O CP B-Chemical was O administered O at O doses O of O 50 O , O 100 O and O 200 O mg O . O / O kg O . O i O . O p O . O to O male O rats O , O and O their O behavior O observed O and O scored O . O The O effects O of O morphine B-Chemical ( O 0 O . O 5 O to O 4 O mg O . O / O kg O . O i O . O v O .

O In O addition O , O 90 O minutes O after O CP B-Chemical injection O , O that O is O , O at O the O time O of O administration O of O morphine B-Chemical , O the O bladder O was O removed O in O some O rats O for O histological O examination O . O Finally O , O to O show O that O the O bladder O is O essential O for O the O CP B-Chemical - O induced O behavioral O modifications O , O female O rats O also O received O CP B-Chemical at O doses O of O 200 O mg O . O / O kg O . O i O . O p O . O and O of O 20 O mg O . O by O the O intravesical O route O , O and O acrolein B-Chemical at O doses O of O 0 O . O 5 O mg O . O by O the O intravesical O route O and O of O 5 O mg O . O / O kg O . O i O . O v O . O RESULTS O : O CP B-Chemical dose O - O relatedly O induced O marked O behavioral O modifications O in O male O rats O : O breathing O rate O decrease O , O closing O of O the O eyes O and O occurrence O of O specific O postures O . O Morphine B-Chemical dose O - O dependently O reversed O these O behavioral B-Disease disorders I-Disease . O A O dose O of O 0 O . O 5 O mg O . O / O kg O . O produced O a O reduction O of O almost O 50 O % O of O the O behavioral O score O induced O by O CP B-Chemical 200 O mg O . O / O kg O . O This O effect O was O completely O prevented O by O pretreatment O with O naloxone B-Chemical . O At O the O time O of O administration O of O morphine B-Chemical , O histological O modifications O of O the O bladder O wall O , O such O as O chorionic O and O muscle O layer O edema B-Disease , O were O observed O . O In O female O rats O , O CP B-Chemical 200 O mg O . O / O kg O . O i O . O p O . O produced O the O same O marked O behavioral O modifications O as O those O observed O in O male O rats O . O Administered O at O the O dose O of O 20 O mg O . O intravesically O , O CP B-Chemical did O not O produce O any O behavioral O effects O , O whereas O acrolein B-Chemical at O 0 O . O 5 O mg O . O intravesically O induced O behavioral O modifications O identical O to O those O under O CP B-Chemical 200 O mg O . O / O kg O . O i O . O p O . O , O with O the O same O maximal O levels O . O Conversely O , O acrolein B-Chemical 5 O mg O . O / O kg O . O i O . O v O . O did O not O produce O any O behavioral O effects O at O all O . O CONCLUSIONS O : O Overall O , O these O results O indicate O that O this O experimental O model O of O CP B-Chemical - O induced O cystitis B-Disease may O be O an O interesting O new O behavioral O model O of O inflammatory O visceral B-Disease pain I-Disease , O allowing O a O better O understanding O of O these O painful B-Disease syndromes I-Disease and O thus O a O better O therapeutic O approach O to O them O . O Prednisolone B-Chemical - O induced O muscle B-Disease dysfunction I-Disease is O caused O more O by O atrophy B-Disease than O by O altered O acetylcholine B-Chemical receptor O expression O . O Large O doses O of O glucocorticoids O can O alter O muscle O physiology O and O susceptibility O to O neuromuscular O blocking O drugs O by O mechanisms O not O clearly O understood O . O We O investigated O the O effects O of O moderate O and O large O doses O of O prednisolone B-Chemical on O muscle O function O and O pharmacology O , O and O their O relationship O to O changes O in O muscle O size O and O acetylcholine B-Chemical receptor O ( O AChR O ) O expression O . O With O institutional O approval O , O 35 O Sprague O - O Dawley O rats O were O randomly O allocated O to O receive O daily O subcutaneous O doses O of O 10 O mg O / O kg O prednisolone B-Chemical ( O P10 O group O ) O , O 100 O mg O / O kg O prednisolone B-Chemical ( O P100 O group O ) O , O or O an O equal O volume O of O saline O ( O S O group O ) O for O 7 O days O . O A O fourth O group O of O rats O was O pair O fed O ( O food O restricted O ) O with O the O P100 O rats O for O 7 O days O ( O FR O group O ) O . O On O Day O 8 O , O the O nerve O - O evoked O peak O twitch O tensions O , O tetanic B-Disease tensions O , O and O fatigability O , O and O the O dose O - O response O curves O of O d B-Chemical - I-Chemical tubocurarine I-Chemical in O the O tibialis O cranialis O muscle O were O measured O in O vivo O and O related O to O muscle O mass O or O expression O of O AChRs O . O Rate O of O body O weight O gain O was O depressed O in O the O P100 O , O FR O , O and O P10 O groups O compared O with O the O S O group O . O Tibialis O muscle O mass O was O smaller O in O the O P100 O group O than O in O the O P10 O or O S O groups O . O The O evoked O peak O twitch O and O tetanic B-Disease tensions O were O less O in O the O P100 O group O than O in O the O P10 O or O S O groups O , O however O , O tension O per O milligram O of O muscle O mass O was O greater O in O the O P100 O group O than O in O the O S O group O . O The O 50 O % O effective O dose O of O d B-Chemical - I-Chemical tubocurarine I-Chemical ( O microg O / O kg O ) O in O the O tibialis O muscle O was O smaller O in O the O P10 O ( O 33 O . O 6 O + O / O - O 5 O . O 4 O ) O than O in O the O S O ( O 61 O . O 9 O + O / O - O 5 O . O 0 O ) O or O the O P100 O ( O 71 O . O 3 O + O / O - O 9 O . O 6 O ) O groups O . O AChR O expression O was O less O in O the O P10 O group O than O in O the O S O group O . O The O evoked O tensions O correlated O with O muscle O mass O ( O r O ( O 2 O ) O = O 0 O . O 32 O , O P O < O 0 O . O 001 O ) O , O however O , O not O with O expression O of O AChR O . O The O 50 O % O effective O dose O of O d B-Chemical - I-Chemical tubocurarine I-Chemical did O not O correlate O with O muscle O mass O or O AChR O expression O . O Our O results O suggest O that O the O neuromuscular B-Disease dysfunction I-Disease after O prednisolone B-Chemical is O dose O - O dependent O , O and O derives O primarily O from O muscle B-Disease atrophy I-Disease and O derives O less O so O from O changes O in O AChR O expression O . O IMPLICATIONS O : O The O mechanisms O by O which O chronic O glucocorticoid O therapy O alters O neuromuscular O physiology O and O pharmacology O are O unclear O . O We O suggest O that O the O observed O effects O are O dose O - O dependent O and O derive O primarily O from O muscle B-Disease atrophy I-Disease and O derive O less O from O changes O in O acetylcholine B-Chemical receptor O expression O . O Apomorphine B-Chemical : O an O underutilized O therapy O for O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease . O Apomorphine B-Chemical was O the O first O dopaminergic O drug O ever O used O to O treat O symptoms O of O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease . O While O powerful O antiparkinsonian O effects O had O been O observed O as O early O as O 1951 O , O the O potential O of O treating O fluctuating O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease by O subcutaneous O administration O of O apomorphine B-Chemical has O only O recently O become O the O subject O of O systematic O study O . O A O number O of O small O scale O clinical O trials O have O unequivocally O shown O that O intermittent O subcutaneous O apomorphine B-Chemical injections O produce O antiparkinsonian O benefit O close O if O not O identical O to O that O seen O with O levodopa B-Chemical and O that O apomorphine B-Chemical rescue O injections O can O reliably O revert O off O - O periods O even O in O patients O with O complex O on O - O off O motor O swings O . O Continuous O subcutaneous O apomorphine B-Chemical infusions O can O reduce O daily O off O - O time O by O more O than O 50 O % O in O this O group O of O patients O , O which O appears O to O be O a O stronger O effect O than O that O generally O seen O with O add O - O on O therapy O with O oral O dopamine B-Chemical agonists O or O COMT O inhibitors O . O Extended O follow O - O up O studies O of O up O to O 8 O years O have O demonstrated O long O - O term O persistence O of O apomorphine B-Chemical efficacy O . O In O addition O , O there O is O convincing O clinical O evidence O that O monotherapy O with O continuous O subcutaneous O apomorphine B-Chemical infusions O is O associated O with O marked O reductions O of O preexisting O levodopa B-Chemical - O induced O dyskinesias B-Disease . O The O main O side O effects O of O subcutaneous O apomorphine B-Chemical treatment O are O related O to O cutaneous O tolerability O problems O , O whereas O sedation O and O psychiatric B-Disease complications O play O a O lesser O role O . O Given O the O marked O degree O of O efficacy O of O subcutaneous O apomorphine B-Chemical treatment O in O fluctuating O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease , O this O approach O seems O to O deserve O more O widespread O clinical O use O . O Probing O peripheral O and O central O cholinergic O system O responses O . O OBJECTIVE O : O The O pharmacological O response O to O drugs O that O act O on O the O cholinergic O system O of O the O iris O has O been O used O to O predict O deficits O in O central O cholinergic O functioning O due O to O diseases O such O as O Alzheimer B-Disease ' I-Disease s I-Disease disease I-Disease , O yet O correlations O between O central O and O peripheral O responses O have O not O been O properly O studied O . O This O study O assessed O the O effect O of O normal O aging O on O ( O 1 O ) O the O tropicamide B-Chemical - O induced O increase O in O pupil O diameter O , O and O ( O 2 O ) O the O reversal O of O this O effect O with O pilocarpine B-Chemical . O Scopolamine B-Chemical was O used O as O a O positive O control O to O detect O age O - O dependent O changes O in O central O cholinergic O functioning O in O the O elderly O . O DESIGN O : O Randomized O double O - O blind O controlled O trial O . O PARTICIPANTS O : O Ten O healthy O elderly O ( O mean O age O 70 O ) O and O 9 O young O ( O mean O age O 33 O ) O volunteers O . O INTERVENTIONS O : O Pupil O diameter O was O monitored O using O a O computerized O infrared O pupillometer O over O 4 O hours O . O The O study O involved O 4 O sessions O . O In O 1 O session O , O tropicamide B-Chemical ( O 20 O microL O , O 0 O . O 01 O % O ) O was O administered O to O one O eye O and O placebo O to O the O other O . O In O another O session O , O tropicamide B-Chemical ( O 20 O microL O , O 0 O . O 01 O % O ) O was O administered O to O both O eyes O , O followed O 23 O minutes O later O by O the O application O of O pilocarpine B-Chemical ( O 20 O microL O , O 0 O . O 1 O % O ) O to O one O eye O and O placebo O to O the O other O . O All O eye O drops O were O given O in O a O randomized O order O . O In O 2 O separate O sessions O , O a O single O dose O of O scopolamine B-Chemical ( O 0 O . O 5 O mg O , O intravenously O ) O or O placebo O was O administered O , O and O the O effects O on O word O recall O were O measured O using O the O Buschke O Selective O Reminding O Test O over O 2 O hours O . O OUTCOME O MEASURES O : O Pupil O size O at O time O points O after O administration O of O tropicamide B-Chemical and O pilocarpine B-Chemical ; O scopolamine B-Chemical - O induced O impairment B-Disease in I-Disease word I-Disease recall I-Disease . O RESULTS O : O There O was O no O significant O difference O between O elderly O and O young O volunteers O in O pupillary O response O to O tropicamide B-Chemical at O any O time O point O ( O p O > O 0 O . O 05 O ) O . O The O elderly O group O had O a O significantly O greater O pilocarpine B-Chemical - O induced O net O decrease O in O pupil O size O 85 O , O 125 O , O 165 O and O 215 O minutes O after O administration O , O compared O with O the O young O group O ( O p O < O 0 O .

O This O study O was O designed O to O describe O pain B-Disease tolerance O and O analgesic O response O in O a O sample O of O opioid B-Disease addicts I-Disease stabilized O in O methadone B-Chemical - O maintenance O ( O MM O ) O treatment O ( O n O = O 60 O ) O in O comparison O to O matched O nondependent O control O subjects O ( O n O = O 60 O ) O . O By O using O a O placebo O - O controlled O , O two O - O way O factorial O design O , O tolerance O to O cold O - O pressor O ( O CP O ) O pain B-Disease was O examined O , O both O before O and O after O oral O administration O of O therapeutic O doses O of O common O opioid O ( O hydromorphone B-Chemical 2 O mg O ) O and O nonsteroidal O anti O - O inflammatory O ( O ketorolac B-Chemical 10 O mg O ) O analgesic O agents O . O Results O showed O that O MM O individuals O were O significantly O less O tolerant O of O CP O pain B-Disease than O control O subjects O , O replicating O previous O work O . O Analgesic O effects O were O significant O neither O for O medication O nor O group O . O These O data O indicate O that O MM O opioid O abusers O represent O a O pain B-Disease - I-Disease intolerant I-Disease subset O of O clinical O patients O . O Their O complaints O of O pain B-Disease should O be O evaluated O seriously O and O managed O aggressively O . O High O - O dose O methylprednisolone B-Chemical may O do O more O harm O for O spinal B-Disease cord I-Disease injury I-Disease . O Because O of O the O National O Acute O Spinal B-Disease Cord I-Disease Injury I-Disease Studies O ( O NASCIS O ) O , O high O - O dose O methylprednisolone B-Chemical became O the O standard O of O care O for O the O acute O spinal B-Disease cord I-Disease injury I-Disease . O In O the O NASCIS O , O there O was O no O mention O regarding O the O possibility O of O acute O corticosteroid B-Chemical myopathy B-Disease that O high O - O dose O methylprednisolone B-Chemical may O cause O . O The O dosage O of O methylprednisolone B-Chemical recommended O by O the O NASCIS O 3 O is O the O highest O dose O of O steroids B-Chemical ever O being O used O during O a O 2 O - O day O period O for O any O clinical O condition O . O We O hypothesize O that O it O may O cause O some O damage B-Disease to I-Disease the I-Disease muscle I-Disease of O spinal B-Disease cord I-Disease injury I-Disease patients O . O Further O , O steroid B-Chemical myopathy B-Disease recovers O naturally O and O the O neurological O improvement O shown O in O the O NASCIS O may O be O just O a O recording O of O this O natural O motor O recovery O from O the O steroid B-Chemical myopathy B-Disease , O instead O of O any O protection O that O methylprednisolone B-Chemical offers O to O the O spinal B-Disease cord I-Disease injury I-Disease . O To O our O knowledge O , O this O is O the O first O discussion O considering O the O possibility O that O the O methylprednisolone B-Chemical recommended O by O NASCIS O may O cause O acute O corticosteroid B-Chemical myopathy B-Disease . O Conversion O to O rapamycin B-Chemical immunosuppression O in O renal O transplant O recipients O : O report O of O an O initial O experience O . O BACKGROUND O : O The O aim O of O this O study O is O to O evaluate O the O effects O of O RAPA B-Chemical conversion O in O patients O undergoing O cyclosporine B-Chemical ( O CsA B-Chemical ) O or O tacrolimus B-Chemical ( O Tac B-Chemical ) O toxicity B-Disease . O METHODS O : O Twenty O renal O transplant O recipients O were O switched O to O fixed O dose O rapamycin B-Chemical ( O RAPA B-Chemical ) O ( O 5 O mg O / O day O ) O 0 O to O 204 O months O posttransplant O . O Drug O monitoring O was O not O initially O used O to O adjust O doses O . O The O indications O for O switch O were O chronic O CsA B-Chemical or O Tac B-Chemical nephrotoxicity B-Disease ( O 12 O ) O , O acute O CsA B-Chemical or O Tac B-Chemical toxicity B-Disease ( O 3 O ) O , O severe O facial B-Disease dysmorphism I-Disease ( O 2 O ) O , O posttransplant B-Disease lymphoproliferative I-Disease disorder I-Disease ( O PTLD B-Disease ) O in O remission O ( O 2 O ) O , O and O hepatotoxicity B-Disease in O 1 O . O Follow O - O up O is O 7 O to O 24 O months O . O RESULTS O : O In O the O 12 O patients O switched O because O of O chronic O nephrotoxicity B-Disease there O was O a O significant O decrease O in O serum O creatinine B-Chemical [ O 233 O + O / O - O 34 O to O 210 O + O / O - O 56 O micromol O / O liter O ( O P O < O 0 O . O 05 O ) O at O 6 O months O ] O . O Facial B-Disease dysmorphism I-Disease improved O in O two O patients O . O No O relapse O of O PTLD B-Disease was O observed O . O Five O patients O developed O pneumonia B-Disease ( O two O Pneumocystis B-Disease carinii I-Disease pneumonia I-Disease , O one O infectious B-Disease mononucleosis I-Disease with O polyclonal O PTLD B-Disease lung O infiltrate O ) O and O two O had O bronchiolitis B-Disease obliterans I-Disease . O There O were O no O deaths O . O RAPA B-Chemical was O discontinued O in O four O patients O , O because O of O pneumonia B-Disease in O two O , O PTLD B-Disease in O one O , O and O oral O aphtous B-Disease ulcers I-Disease in O one O . O RAPA B-Chemical levels O were O high O ( O > O 15 O ng O / O ml O ) O in O 7 O of O 13 O ( O 54 O % O ) O patients O . O CONCLUSIONS O : O RAPA B-Chemical conversion O provides O adequate O immunosuppression O to O enable O CsA B-Chemical withdrawal O . O However O , O when O converting O patients O to O RAPA B-Chemical drug O levels O should O be O monitored O to O avoid O over O - O immunosuppression O and O adequate O antiviral O and O Pneumocystis B-Disease carinii I-Disease pneumonia I-Disease prophylaxis O should O be O given O . O Electro O - O oculography O , O electroretinography O , O visual O evoked O potentials O , O and O multifocal O electroretinography O in O patients O with O vigabatrin B-Chemical - O attributed O visual B-Disease field I-Disease constriction I-Disease . O PURPOSE O : O Symptomatic O visual B-Disease field I-Disease constriction I-Disease thought O to O be O associated O with O vigabatrin B-Chemical has O been O reported O . O The O current O study O investigated O the O visual O fields O and O visual O electrophysiology O of O eight O patients O with O known O vigabatrin B-Chemical - O attributed O visual B-Disease field I-Disease loss I-Disease , O three O of O whom O were O reported O previously O . O Six O of O the O patients O were O no O longer O receiving O vigabatrin B-Chemical . O METHODS O : O The O central O and O peripheral O fields O were O examined O with O the O Humphrey O Visual O Field O Analyzer O . O Full O visual O electrophysiology O , O including O flash O electroretinography O ( O ERG O ) O , O pattern O electroretinography O , O multifocal O ERG O using O the O VERIS O system O , O electro O - O oculography O , O and O flash O and O pattern O visual O evoked O potentials O , O was O undertaken O . O RESULTS O : O Seven O patients O showed O marked O visual B-Disease field I-Disease constriction I-Disease with O some O sparing O of O the O temporal O visual O field O . O The O eighth O exhibited O concentric O constriction O . O Most O electrophysiological O responses O were O usually O just O within O normal O limits O ; O two O patients O had O subnormal O Arden O electro O - O oculography O indices O ; O and O one O patient O showed O an O abnormally O delayed O photopic O b O wave O . O However O , O five O patients O showed O delayed O 30 O - O Hz O flicker O b O waves O , O and O seven O patients O showed O delayed O oscillatory O potentials O . O Multifocal O ERG O showed O abnormalities O that O sometimes O correlated O with O the O visual O field O appearance O and O confirmed O that O the O deficit O occurs O at O the O retinal O level O . O CONCLUSION O : O Marked O visual B-Disease field I-Disease constriction I-Disease appears O to O be O associated O with O vigabatrin B-Chemical therapy O . O The O field O defects O and O some O electrophysiological O abnormalities O persist O when O vigabatrin B-Chemical therapy O is O withdrawn O . O Myocardial B-Disease ischemia I-Disease due O to O coronary B-Disease artery I-Disease spasm I-Disease during O dobutamine B-Chemical stress O echocardiography O . O Dobutamine B-Chemical stress O echocardiography O ( O DSE O ) O is O a O useful O and O safe O provocation O test O for O myocardial B-Disease ischemia I-Disease . O Until O now O , O the O test O has O been O focused O only O on O the O organic O lesion O in O the O coronary O artery O , O and O positive O DSE O has O indicated O the O presence O of O significant O fixed O coronary B-Disease artery I-Disease stenosis I-Disease . O The O aim O of O the O present O study O is O to O examine O whether O myocardial B-Disease ischemia I-Disease due O to O coronary B-Disease spasm I-Disease is O induced O by O dobutamine B-Chemical . O We O performed O DSE O on O 51 O patients O with O coronary B-Disease spastic I-Disease angina I-Disease but O without O significant O fixed O coronary B-Disease artery I-Disease stenosis I-Disease . O All O patients O had O anginal B-Disease attacks O at O rest O with O ST O elevation O on O the O electrocardiogram O ( O variant B-Disease angina I-Disease ) O . O Coronary O spasm O was O induced O by O intracoronary O injection O of O acetylcholine B-Chemical , O and O no O fixed O coronary B-Disease artery I-Disease stenosis I-Disease was O documented O on O angiograms O in O all O patients O . O DSE O was O performed O with O intravenous O dobutamine B-Chemical infusion O with O an O incremental O doses O of O 5 O , O 10 O , O 20 O , O 30 O , O and O 40 O microg O / O kg O / O min O every O 5 O minutes O . O Of O the O 51 O patients O , O 7 O patients O showed O asynergy O with O ST O elevation O . O All O 7 O patients O ( O 13 O . O 7 O % O ) O had O chest B-Disease pain I-Disease during O asynergy O , O and O both O chest B-Disease pain I-Disease and O electrocardiographic O changes O were O preceded O by O asynergy O . O These O findings O indicate O that O dobutamine B-Chemical can O provoke O coronary B-Disease spasm I-Disease in O some O patients O with O coronary B-Disease spastic I-Disease angina I-Disease . O When O DSE O is O performed O to O evaluate O coronary B-Disease artery I-Disease disease I-Disease , O not O only O fixed O coronary B-Disease stenosis I-Disease , O but O also O coronary B-Disease spasm I-Disease should O be O considered O as O a O genesis O of O asynergy O . O Effect O of O intravenous O metoprolol B-Chemical or O intravenous O metoprolol B-Chemical plus O glucagon O on O dobutamine B-Chemical - O induced O myocardial B-Disease ischemia I-Disease . O STUDY O OBJECTIVE O : O To O determine O the O effect O of O metoprolol B-Chemical on O dobutamine B-Chemical stress O testing O with O technetium B-Chemical - I-Chemical 99m I-Chemical sestamibi I-Chemical single O - O photon O emission O computed O tomography O imaging O and O ST O - O segment O monitoring O , O and O to O assess O the O impact O of O intravenous O glucagon O on O metoprolol B-Chemical ' O s O effects O . O DESIGN O : O Randomized O , O double O - O blind O , O placebo O - O controlled O trial O . O SETTING O : O Community O hospital O . O PATIENTS O : O Twenty O - O two O patients O with O known O reversible O perfusion O defects O . O INTERVENTION O : O Patients O underwent O dobutamine B-Chemical stress O tests O per O standard O protocol O . O Before O dobutamine B-Chemical was O begun O , O no O therapy O was O given O during O the O first O visit O , O and O patients O were O randomized O on O subsequent O visits O to O receive O metoprolol B-Chemical or O metoprolol B-Chemical plus O glucagon O 1 O mg O . O Metoprolol B-Chemical was O dosed O to O achieve O a O resting O predobutamine B-Chemical heart O rate O below O 65 O beats O / O minute O or O a O total O intravenous O dose O of O 20 O mg O . O MEASUREMENTS O AND O MAIN O RESULTS O : O Metoprolol B-Chemical reduced O maximum O heart O rate O 31 O % O , O summed O stress O scores O 29 O % O , O and O summed O difference O scores O 43 O % O versus O control O . O Metoprolol B-Chemical plus O glucagon O also O reduced O the O maximum O heart O rate O 29 O % O versus O control O . O Summed O stress O and O summed O difference O scores O were O not O significantly O reduced O , O although O they O were O 18 O % O and O 30 O % O lower O , O respectively O , O than O control O . O No O significant O differences O were O found O in O any O parameter O between O metoprolol B-Chemical and O metoprolol B-Chemical - O glucagon O . O CONCLUSION O : O During O dobutamine B-Chemical stress O testing O , O metoprolol B-Chemical attenuates O or O eliminates O evidence O of O myocardial B-Disease ischemia I-Disease . O Glucagon O 1 O mg O , O although O somewhat O effective O , O does O not O correct O this O effect O to O the O extent O that O it O can O be O administered O clinically O . O Evidence O of O functional O somatotopy O in O GPi O from O results O of O pallidotomy O . O The O objective O of O this O study O was O to O explore O the O functional O anatomy O of O the O globus O pallidus O internus O ( O GPi O ) O by O studying O the O effects O of O unilateral O pallidotomy O on O parkinsonian B-Disease ' O off O ' O signs O and O levodopa B-Chemical - O induced O dyskinesias B-Disease ( O LID B-Disease ) O . O We O found O significant O positive O correlations O between O the O preoperative O levodopa B-Chemical responsiveness O of O motor O signs O and O the O levodopa B-Chemical responsiveness O of O scores O in O timed O tests O ( O Core O Assessment O Program O for O Intracerebral O Transplantations O ) O in O the O contralateral O limbs O and O the O improvement O in O these O scores O after O surgery O , O whereas O there O was O no O correlation O with O the O improvement O in O LID B-Disease . O We O also O found O a O highly O significant O correlation O ( O P O : O < O 0 O . O 0001 O , O r O = O 0 O . O 8 O ) O between O the O volume O of O the O ventral O lesion O in O the O GPi O and O the O improvement O in O LID B-Disease in O the O contralateral O limbs O , O whereas O there O was O no O correlation O between O the O ventral O volume O and O the O improvement O in O parkinsonian B-Disease ' O off O ' O signs O . O The O volumes O of O the O total O lesion O cylinder O and O the O dorsal O lesion O did O not O correlate O with O the O outcome O of O either O dyskinesias B-Disease or O parkinsonian B-Disease ' O off O ' O signs O . O The O differential O predictive O value O of O levodopa B-Chemical responsiveness O for O the O outcome O of O parkinsonian B-Disease ' O off O ' O signs O and O LID B-Disease and O the O different O correlations O of O ventral O lesion O volume O with O dyskinesias B-Disease and O parkinsonian B-Disease ' O off O ' O signs O indicate O that O different O anatomical O or O pathophysiological O substrates O may O be O responsible O for O the O generation O of O parkinsonian B-Disease ' O off O ' O signs O and O dyskinesias B-Disease . O Whereas O cells O in O a O wider O area O of O the O GPi O may O be O implicated O in O parkinsonism B-Disease , O the O ventral O GPi O seems O to O be O crucial O for O the O manifestation O of O LID B-Disease . O We O suggest O that O our O observations O are O additional O proof O of O the O functional O somatotopy O of O the O systems O within O the O GPi O that O mediate O parkinsonism B-Disease and O dyskinesias B-Disease , O especially O along O the O dorsoventral O trajectory O used O in O pallidotomy O . O The O outcome O of O pallidotomy O in O which O the O lesion O involves O the O ventral O and O dorsal O GPi O could O be O the O net O effect O of O alteration O in O the O activity O of O pathways O which O mediate O different O symptoms O , O and O hence O could O be O variable O . O Screening O for O stimulant O use O in O adult O emergency O department O seizure B-Disease patients O . O OBJECTIVE O : O The O objective O of O this O study O was O to O determine O the O prevalence O of O positive O plasma O drug O screening O for O cocaine B-Chemical or O amphetamine B-Chemical in O adult O emergency O department O seizure B-Disease patients O . O METHODS O : O This O prospective O study O evaluated O consecutive O eligible O seizure B-Disease patients O who O had O a O plasma O sample O collected O as O part O of O their O clinical O evaluation O . O Plasma O was O tested O for O amphetamine B-Chemical and O the O cocaine B-Chemical metabolite O benzoylecgonine B-Chemical using O enzyme O - O mediated O immunoassay O methodology O . O Plasma O samples O with O benzoylecgonine B-Chemical greater O than O 150 O ng O / O mL O or O an O amphetamine B-Chemical greater O than O 500 O ng O / O mL O were O defined O as O positive O . O Patient O demographics O , O history O of O underlying O drug O or O alcohol B-Chemical - O related O seizure B-Disease disorder O , O estimated O time O from O seizure B-Disease to O sample O collection O , O history O or O suspicion O of O cocaine B-Disease or I-Disease amphetamine I-Disease abuse I-Disease , O results O of O clinical O urine O testing O for O drugs O of O abuse O , O and O assay O results O were O recorded O without O patient O identifiers O . O RESULTS O : O Fourteen O of O 248 O ( O 5 O . O 6 O % O , O 95 O % O CI O 2 O . O 7 O % O - O 8 O . O 5 O % O ) O plasma O samples O were O positive O by O immunoassay O testing O for O benzoylecgonine B-Chemical and O no O samples O ( O 0 O % O , O 95 O % O CI O 0 O - O 1 O . O 2 O % O ) O were O positive O for O amphetamine B-Chemical . O Positive O test O results O were O more O common O in O patient O visits O where O there O was O a O history O or O suspicion O of O cocaine B-Disease or I-Disease amphetamine I-Disease abuse I-Disease ( O p O < O 0 O . O 0005 O ) O . O CONCLUSIONS O : O During O this O study O period O , O routine O plasma O screening O for O cocaine B-Chemical and O amphetamines B-Chemical in O adult O seizure B-Disease patients O had O a O low O yield O . O As O a O result O , O routine O plasma O screening O would O yield O few O cases O of O stimulant O drug O in O which O there O was O neither O a O history O nor O suspicion O of O drug B-Disease abuse I-Disease in O this O population O . O Contribution O of O sodium B-Chemical valproate I-Chemical to O the O syndrome B-Disease of I-Disease inappropriate I-Disease secretion I-Disease of I-Disease antidiuretic I-Disease hormone I-Disease . O We O report O the O case O of O a O 62 O - O year O - O old O man O who O was O administered O sodium B-Chemical valproate I-Chemical ( O VPA B-Chemical ) O and O who O subsequently O developed O the O syndrome B-Disease of I-Disease inappropriate I-Disease secretion I-Disease of I-Disease antidiuretic I-Disease hormone I-Disease ( O SIADH B-Disease ) O . O He O had O been O taking O VPA B-Chemical for O treatment O of O idiopathic O generalized O tonic B-Disease - I-Disease clonic I-Disease convulsions I-Disease since O he O was O 56 O years O old O . O After O substituting O VPA B-Chemical with O zonisamide B-Chemical , O the O serum O sodium B-Chemical level O returned O to O normal O . O We O consider O this O episode O of O SIADH B-Disease to O be O the O result O of O a O combination O of O factors O including O a O weakness B-Disease of I-Disease the I-Disease central I-Disease nervous I-Disease system I-Disease and O the O long O - O term O administration O of O VPA B-Chemical . O Association O of O nitric B-Chemical oxide I-Chemical production O and O apoptosis O in O a O model O of O experimental O nephropathy B-Disease . O BACKGROUND O : O In O recent O studies O increased O amounts O of O nitric B-Chemical oxide I-Chemical ( O NO B-Chemical ) O and O apoptosis O have O been O implicated O in O various O pathological O conditions O in O the O kidney O . O We O have O studied O the O role O of O NO B-Chemical and O its O association O with O apoptosis O in O an O experimental O model O of O nephrotic B-Disease syndrome I-Disease induced O by O a O single O injection O of O adriamycin B-Chemical ( O ADR B-Chemical ) O . O METHODS O : O The O alteration O in O the O NO B-Chemical pathway O was O assessed O by O measuring O nitrite B-Chemical levels O in O serum O / O urine O and O by O evaluating O the O changes O in O vascular O reactivity O of O the O isolated O perfused O rat O kidney O ( O IPRK O ) O system O . O Rats O were O stratified O into O control O groups O and O ADR B-Chemical - O induced O nephropathy B-Disease groups O . O These O two O groups O were O then O divided O into O : O group O 1 O , O animals O receiving O saline O ; O and O group O 2 O , O animals O receiving O aminoguanidine B-Chemical ( O AG B-Chemical ) O which O is O a O specific O inhibitor O of O inducible O - O NO B-Chemical synthase O . O On O day O 21 O , O rats O were O sacrificed O after O obtaining O material O for O biochemical O analysis O . O RESULTS O : O Histopathological O examination O of O the O kidneys O of O rats O treated O with O ADR B-Chemical revealed O focal O areas O of O mesangial B-Disease proliferation I-Disease and O mild O tubulointerstitial B-Disease inflammation I-Disease . O They O also O had O significantly O higher O levels O of O proteinuria B-Disease compared O with O control O and O treatment O groups O ( O P O < O 0 O . O 05 O ) O . O Urine O nitrite B-Chemical levels O were O significantly O increased O in O the O ADR B-Chemical - O nephropathy B-Disease group O ( O P O < O 0 O . O 05 O ) O . O In O the O IPRK O phenylephrine B-Chemical and O acetylcholine B-Chemical related O responses O were O significantly O impaired O in O the O ADR B-Chemical - O nephropathy B-Disease group O . O Apoptosis O was O not O detected O in O controls O . O However O , O in O the O ADR B-Chemical - O nephropathy B-Disease group O , O numerous O apoptotic O cells O were O identified O in O the O tubulointerstitial O areas O . O Double O staining O revealed O numerous O interstitial O apoptotic O cells O to O stain O for O ED1 O , O a O marker O for O monocytes O / O macrophages O . O Treatment O with O AG B-Chemical prevented O the O impairment O of O renal O vascular O bed O responses O and O reduced O both O urine O nitrite B-Chemical levels O and O apoptosis O to O control O levels O . O CONCLUSION O : O We O suggest O that O interactions O between O NO B-Chemical and O apoptosis O are O important O in O the O pathogenesis O of O the O ADR B-Chemical - O induced O nephrosis B-Disease . O Dual O effects O of O melatonin B-Chemical on O barbiturate B-Chemical - O induced O narcosis B-Disease in O rats O . O Melatonin B-Chemical affects O the O circadian O sleep O / O wake O cycle O , O but O it O is O not O clear O whether O it O may O influence O drug O - O induced O narcosis B-Disease . O Sodium B-Chemical thiopenthal I-Chemical was O administered O intraperitoneally O into O male O rats O pre O - O treated O with O melatonin B-Chemical ( O 0 O . O 05 O , O 0 O . O 5 O , O 5 O and O 50 O mg O / O kg O ) O . O Melatonin B-Chemical pre O - O treatment O affected O in O a O dual O manner O barbiturate B-Chemical narcosis B-Disease , O however O , O no O dose O - O effect O correlation O was O found O . O In O particular O , O low O doses O reduced O the O latency O to O and O prolonged O the O duration O of O barbiturate B-Chemical narcosis B-Disease . O In O contrast O , O the O highest O dose O of O melatonin B-Chemical ( O 50 O mg O / O kg O ) O caused O a O paradoxical O increase O in O the O latency O and O produced O a O sustained O reduction O of O the O duration O of O narcosis B-Disease , O and O a O reduction O in O mortality O rate O . O Melatonin B-Chemical 0 O . O 5 O and O 5 O mg O / O kg O influenced O the O duration O but O not O the O latency O of O ketamine B-Chemical - O or O diazepam B-Chemical - O induced O narcosis B-Disease . O Thus O , O the O dual O action O of O melatonin B-Chemical on O pharmacological O narcosis B-Disease seems O to O be O specific O for O the O barbiturate B-Chemical mechanism O of O action O . O Reduced O cardiotoxicity B-Disease and O preserved O antitumor O efficacy O of O liposome O - O encapsulated O doxorubicin B-Chemical and O cyclophosphamide B-Chemical compared O with O conventional O doxorubicin B-Chemical and O cyclophosphamide B-Chemical in O a O randomized O , O multicenter O trial O of O metastatic O breast B-Disease cancer I-Disease . O PURPOSE O : O To O determine O whether O Myocet B-Chemical ( O liposome O - O encapsulated O doxorubicin B-Chemical ; O The O Liposome O Company O , O Elan O Corporation O , O Princeton O , O NJ O ) O in O combination O with O cyclophosphamide B-Chemical significantly O reduces O doxorubicin B-Chemical cardiotoxicity B-Disease while O providing O comparable O antitumor O efficacy O in O first O - O line O treatment O of O metastatic O breast B-Disease cancer I-Disease ( O MBC B-Disease ) O . O PATIENTS O AND O METHODS O : O Two O hundred O ninety O - O seven O patients O with O MBC B-Disease and O no O prior O chemotherapy O for O metastatic O disease O were O randomized O to O receive O either O 60 O mg O / O m O ( O 2 O ) O of O Myocet B-Chemical ( O M O ) O or O conventional O doxorubicin B-Chemical ( O A O ) O , O in O combination O with O 600 O mg O / O m O ( O 2 O ) O of O cyclophosphamide B-Chemical ( O C O ) O , O every O 3 O weeks O until O disease O progression O or O unacceptable O toxicity B-Disease . O Cardiotoxicity B-Disease was O defined O by O reductions O in O left O - O ventricular O ejection O fraction O , O assessed O by O serial O multigated O radionuclide O angiography O scans O , O or O congestive B-Disease heart I-Disease failure I-Disease ( O CHF B-Disease ) O . O Antitumor O efficacy O was O assessed O by O objective O tumor B-Disease response O rates O ( O World O Health O Organization O criteria O ) O , O time O to O progression O , O and O survival O . O RESULTS O : O Six O percent O of O MC O patients O versus O 21 O % O ( O including O five O cases O of O CHF B-Disease ) O of O AC O patients O developed O cardiotoxicity B-Disease ( O P O = O . O 0002 O ) O . O Median O cumulative O doxorubicin B-Chemical dose O at O onset O was O more O than O 2 O , O 220 O mg O / O m O ( O 2 O ) O for O MC O versus O 480 O mg O / O m O ( O 2 O ) O for O AC O ( O P O = O . O 0001 O , O hazard O ratio O , O 5 O . O 04 O ) O . O MC O patients O also O experienced O less O grade O 4 O neutropenia B-Disease . O Antitumor O efficacy O of O MC O versus O AC O was O comparable O : O objective O response O rates O , O 43 O % O versus O 43 O % O ; O median O time O to O progression O , O 5 O .

O Effects O of O verapamil B-Chemical on O atrial B-Disease fibrillation I-Disease and O its O electrophysiological O determinants O in O dogs O . O BACKGROUND O : O Atrial B-Disease tachycardia I-Disease - O induced O remodeling O promotes O the O occurrence O and O maintenance O of O atrial B-Disease fibrillation I-Disease ( O AF B-Disease ) O and O decreases O L O - O type O Ca B-Chemical ( O 2 O + O ) O current O . O There O is O also O a O clinical O suggestion O that O acute O L O - O type O Ca B-Chemical ( O 2 O ) O channel O blockade O can O promote O AF B-Disease , O consistent O with O an O AF B-Disease promoting O effect O of O Ca B-Chemical ( O 2 O + O ) O channel O inhibition O . O METHODS O : O To O evaluate O the O potential O mechanisms O of O AF B-Disease promotion O by O Ca B-Chemical ( O 2 O + O ) O channel O blockers O , O we O administered O verapamil B-Chemical to O morphine B-Chemical - O chloralose B-Chemical anesthetized O dogs O . O Diltiazem B-Chemical was O used O as O a O comparison O drug O and O autonomic O blockade O with O atropine B-Chemical and O nadolol B-Chemical was O applied O in O some O experiments O . O Epicardial O mapping O with O 240 O epicardial O electrodes O was O used O to O evaluate O activation O during O AF B-Disease . O RESULTS O : O Verapamil B-Chemical caused O AF B-Disease promotion O in O six O dogs O , O increasing O mean O duration O of O AF B-Disease induced O by O burst O pacing O , O from O 8 O + O / O - O 4 O s O ( O mean O + O / O - O S O .

O Underlying O electrophysiological O mechanisms O were O studied O in O detail O in O five O additional O dogs O under O control O conditions O and O in O the O presence O of O the O higher O dose O of O verapamil B-Chemical . O In O these O experiments O , O verapamil B-Chemical shortened O mean O effective O refractory O period O ( O ERP O ) O from O 122 O + O / O - O 5 O to O 114 O + O / O - O 4 O ms O ( O P O < O 0 O . O 02 O ) O at O a O cycle O length O of O 300 O ms O , O decreased O ERP O heterogeneity O ( O from O 15 O + O / O - O 1 O to O 10 O + O / O - O 1 O % O , O P O < O 0 O . O 05 O ) O , O heterogeneously O accelerated O atrial O conduction O and O decreased O the O cycle O length O of O AF B-Disease ( O 94 O + O / O - O 4 O to O 84 O + O / O - O 3 O ms O , O P O < O 0 O . O 005 O ) O . O Diltiazem B-Chemical did O not O affect O ERP O , O AF B-Disease cycle O length O or O AF B-Disease duration O , O but O produced O conduction O acceleration O similar O to O that O caused O by O verapamil B-Chemical ( O n O = O 5 O ) O . O In O the O presence O of O autonomic O blockade O , O verapamil B-Chemical failed O to O promote O AF B-Disease and O increased O , O rather O than O decreasing O , O refractoriness O . O Neither O verapamil B-Chemical nor O diltiazem B-Chemical affected O atrial O conduction O in O the O presence O of O autonomic O blockade O . O Epicardial O mapping O suggested O that O verapamil B-Chemical promoted O AF B-Disease by O increasing O the O number O of O simultaneous O wavefronts O reflected O by O separate O zones O of O reactivation O in O each O cycle O . O CONCLUSIONS O : O Verapamil B-Chemical promotes O AF B-Disease in O normal O dogs O by O promoting O multiple O circuit O reentry O , O an O effect O dependent O on O intact O autonomic O tone O and O not O shared O by O diltiazem B-Chemical . O Calcitonin O gene O - O related O peptide O levels O during O nitric B-Chemical oxide I-Chemical - O induced O headache B-Disease in O patients O with O chronic O tension B-Disease - I-Disease type I-Disease headache I-Disease . O It O has O been O proposed O that O nitric B-Chemical oxide I-Chemical ( O NO B-Chemical ) O induced O headache B-Disease in O primary B-Disease headaches I-Disease may O be O associated O with O release O of O calcitonin O gene O - O related O peptide O ( O CGRP O ) O . O In O the O present O study O we O aimed O to O investigate O plasma O levels O of O CGRP O during O headache B-Disease induced O by O the O NO B-Chemical donor O glyceryl B-Chemical trinitrate I-Chemical ( O GTN B-Chemical ) O in O 16 O patients O with O chronic O tension B-Disease - I-Disease type I-Disease headache I-Disease and O 16 O healthy O controls O . O The O subjects O were O randomly O allocated O to O receive O 0 O . O 5 O microg O / O kg O / O min O GTN B-Chemical or O placebo O over O 20 O min O on O two O headache B-Disease - O free O days O . O Blood O samples O were O collected O at O baseline O , O 10 O , O 20 O and O 60 O min O after O start O of O infusion O . O Both O patients O and O controls O developed O significantly O stronger O immediate O headache B-Disease on O the O GTN B-Chemical day O than O on O the O placebo O day O and O the O headache B-Disease was O significantly O more O pronounced O in O patients O than O in O controls O . O There O was O no O difference O between O the O area O under O the O CGRP O curve O ( O AUCCGRP O ) O on O GTN B-Chemical vs O . O placebo O day O in O either O patients O ( O P O = O 0 O . O 65 O ) O or O controls O ( O P O = O 0 O . O 48 O ) O . O The O AUCCGRP O recorded O on O the O GTN B-Chemical day O did O not O differ O between O patients O and O controls O ( O P O = O 0 O . O 36 O ) O . O Both O in O patients O and O controls O , O CGRP O levels O changed O significantly O over O time O , O on O both O the O GTN B-Chemical and O placebo O days O ( O P O < O 0 O . O 05 O ) O . O The O present O study O indicates O that O NO B-Chemical - O induced O immediate O headache B-Disease is O not O associated O with O release O of O CGRP O . O Fluconazole B-Chemical - O induced O torsade B-Disease de I-Disease pointes I-Disease . O OBJECTIVE O : O To O present O a O case O of O fluconazole B-Chemical - O associated O torsade B-Disease de I-Disease pointes I-Disease ( O TDP B-Disease ) O and O discuss O fluconazole B-Chemical ' O s O role O in O causing O TDP B-Disease . O CASE O SUMMARY O : O A O 68 O - O year O - O old O white O woman O with O Candida O glabrata O isolated O from O a O presacral O abscess O developed O TDP B-Disease eight O days O after O commencing O oral O fluconazole B-Chemical The O patient O had O no O other O risk O factors O for O TDP B-Disease , O including O coronary B-Disease artery I-Disease disease I-Disease , O cardiomyopathy B-Disease , O congestive B-Disease heart I-Disease failure I-Disease , O and O electrolyte O abnormalities O There O was O a O temporal O association O between O the O initiation O of O fluconazole B-Chemical and O TDP B-Disease . O The O TDP B-Disease resolved O when O fluconazole B-Chemical was O discontinued O ; O however O , O the O patient O continued O to O have O premature B-Disease ventricular I-Disease contractions I-Disease and O nonsustained O ventricular B-Disease tachycardia I-Disease ( O NSVT B-Disease ) O until O six O days O after O drug O cessation O DISCUSSION O : O Use O of O the O Naranjo O probability O scale O indicates O a O probable O relationship O between O the O use O of O fluconazole B-Chemical and O the O development O of O TDP B-Disease . O The O possible O mechanism O is O depression B-Disease of O rapidly O activating O delayed O rectifier O potassium B-Chemical currents O . O In O our O patient O , O there O was O no O other O etiology O identified O that O could O explain O QT B-Disease prolongation I-Disease or O TDP B-Disease The O complete O disappearance O of O NSVT B-Disease and O premature B-Disease ventricular I-Disease contractions I-Disease followed O by O normalization O of O QT O interval O after O the O drug O was O stopped O strongly O suggests O fluconazole B-Chemical as O the O etiology O . O CONCLUSIONS O : O Clinicians O should O be O aware O that O fluconazole B-Chemical , O even O at O low O doses O , O may O cause O prolongation B-Disease of I-Disease the I-Disease QT I-Disease interval I-Disease , O leading O to O TDP B-Disease . O Serial O electrocardiographic O monitoring O may O be O considered O when O fluconazole B-Chemical is O administered O in O patients O who O are O at O risk O for O ventricular B-Disease arrhythmias I-Disease . O Cutaneous B-Disease leucocytoclastic I-Disease vasculitis I-Disease associated O with O oxacillin B-Chemical . O A O 67 O - O year O - O old O man O who O was O treated O with O oxacillin B-Chemical for O one O week O because O of O Staphylococcus B-Disease aureus I-Disease bacteremia I-Disease , O developed O renal B-Disease failure I-Disease and O diffuse O , O symmetric O , O palpable O purpuric B-Disease lesions I-Disease on O his O feet O . O Necrotic B-Disease blisters I-Disease were O noted O on O his O fingers O . O Skin O biopsies O showed O findings O diagnostic O of O leucocytoclastic B-Disease vasculitis I-Disease . O Oxacillin B-Chemical was O discontinued O and O patient O was O treated O with O corticosteroids B-Chemical . O The O rash B-Disease disappeared O after O three O weeks O and O renal O function O returned O to O normal O . O Leucocytoclastic B-Disease vasculitis I-Disease presents O as O palpable O purpura B-Disease of O the O lower O extremities O often O accompanied O by O abdominal B-Disease pain I-Disease , O arthralgia B-Disease , O and O renal B-Disease involvement I-Disease . O Etiologic O factors O or O associated O disorders O include O infections B-Disease , O medications O , O collagen B-Disease vascular I-Disease disease I-Disease and O neoplasia B-Disease . O However O , O in O half O of O the O cases O no O etiologic O factor O is O identified O . O Usually O it O is O a O self O - O limited O disorder O , O but O corticosteroid B-Chemical therapy O may O be O needed O in O life O - O threatening O cases O since O early O treatment O with O corticosteroids B-Chemical in O severe O cases O can O prevent O complications O . O Oxacillin B-Chemical should O be O included O among O the O drugs O that O can O cause O leucocytoclastic B-Disease vasculitis I-Disease . O The O renal O pathology O in O a O case O of O lithium B-Chemical - O induced O diabetes B-Disease insipidus I-Disease . O A O case O of O lithium B-Chemical - O induced O diabetes B-Disease insipidus I-Disease is O reported O . O At O necropsy O microscopy O shoed O unique O and O extensive O damage O to O cells O lining O the O distal O nephron O . O It O is O suggested O that O these O changes O represent O a O specific O toxic O effect O of O lithium B-Chemical , O reported O here O for O the O first O time O in O man O . O Cholestatic B-Disease jaundice I-Disease associated O with O the O use O of O metformin B-Chemical . O We O report O a O patient O who O developed O cholestatic B-Disease jaundice I-Disease shortly O after O initiation O of O treatment O with O metformin B-Chemical hydrochloride I-Chemical . O Ultrasound O of O the O liver O and O abdominal O CT O were O normal O . O An O ERCP O showed O normal O biliary O anatomy O . O A O percutaneous O liver O biopsy O was O obtained O showing O marked O cholestasis B-Disease , O with O portal O edema B-Disease , O ductular O proliferation O , O and O acute O inflammation B-Disease . O Metformin B-Chemical hydrochloride I-Chemical was O discontinued O , O and O the O patient O ' O s O jaundice B-Disease resolved O slowly O over O a O period O of O several O months O . O Given O the O onset O of O his O jaundice B-Disease 2 O wk O after O the O initiation O of O metformin B-Chemical , O we O believe O that O this O case O represents O an O example O of O metformin B-Chemical - O associated O hepatotoxicity B-Disease , O the O first O such O case O reported O . O Systemic O toxicity B-Disease and O resuscitation O in O bupivacaine B-Chemical - O , O levobupivacaine B-Chemical - O , O or O ropivacaine B-Chemical - O infused O rats O . O We O compared O the O systemic O toxicity B-Disease of O bupivacaine B-Chemical , O levobupivacaine B-Chemical , O and O ropivacaine B-Chemical in O anesthetized O rats O . O We O also O compared O the O ability O to O resuscitate O rats O after O lethal O doses O of O these O local O anesthetics O . O Bupivacaine B-Chemical , O levobupivacaine B-Chemical , O or O ropivacaine B-Chemical was O infused O at O a O rate O of O 2 O mg O . O kg O ( O - O 1 O ) O . O min O ( O - O 1 O ) O while O electrocardiogram O , O electroencephalogram O , O and O arterial O pressure O were O continuously O monitored O . O When O asystole B-Disease was O recorded O , O drug O infusion O was O stopped O and O a O resuscitation O sequence O was O begun O . O Epinephrine B-Chemical 0 O . O 01 O mg O / O kg O was O administered O at O 1 O - O min O intervals O while O external O cardiac O compressions O were O applied O . O Resuscitation O was O considered O successful O when O a O systolic O arterial O pressure O > O or O = O 100 O mm O Hg O was O achieved O within O 5 O min O . O The O cumulative O doses O of O levobupivacaine B-Chemical and O ropivacaine B-Chemical that O produced O seizures B-Disease were O similar O and O were O larger O than O those O of O bupivacaine B-Chemical . O The O cumulative O doses O of O levobupivacaine B-Chemical that O produced O dysrhythmias B-Disease and O asystole B-Disease were O smaller O than O the O corresponding O doses O of O ropivacaine B-Chemical , O but O they O were O larger O than O those O of O bupivacaine B-Chemical . O The O number O of O successful O resuscitations O did O not O differ O among O groups O . O However O , O a O smaller O dose O of O epinephrine B-Chemical was O required O in O the O Ropivacaine B-Chemical group O than O in O the O other O groups O . O We O conclude O that O the O systemic O toxicity B-Disease of O levobupivacaine B-Chemical is O intermediate O between O that O of O ropivacaine B-Chemical and O bupivacaine B-Chemical when O administered O at O the O same O rate O and O that O ropivacaine B-Chemical - O induced O cardiac B-Disease arrest I-Disease appears O to O be O more O susceptible O to O treatment O than O that O induced O by O bupivacaine B-Chemical or O levobupivacaine B-Chemical . O Amphotericin B-Chemical B I-Chemical - O induced O seizures B-Disease in O a O patient O with O AIDS B-Disease . O OBJECTIVE O : O To O report O a O case O of O multiple O episodes O of O seizure B-Disease activity O in O an O AIDS B-Disease patent O following O amphotericin B-Chemical B I-Chemical infusion O . O CASE O SUMMARY O : O A O 46 O - O year O - O old O African O - O American O man O experienced O recurrent O grand B-Disease mal I-Disease seizures I-Disease during O intravenous O infusion O of O amphotericin B-Chemical B I-Chemical , O then O petit O mal O seizures B-Disease as O the O infusion O was O stopped O and O the O drug O concentrations O decreased O with O time O . O The O patients O concurrent O medications O included O didanosine B-Chemical , O hydroxyzine B-Chemical , O promethazine B-Chemical , O hydrocortisone B-Chemical , O and O prochlorperazine B-Chemical . O Despite O administration O of O phenytoin B-Chemical and O lorazepam B-Chemical , O the O seizures B-Disease persisted O and O occurred O only O during O amphotercin B-Chemical B I-Chemical administration O . O DISCUSSION O : O AIDS B-Disease and O cryptococcal B-Disease meningitis I-Disease , O both O of O which O the O patient O had O , O can O potentially O cause O seizures B-Disease . O The O patient O had O a O history O of O alcohol B-Disease abuse I-Disease ; O alcohol B-Chemical intake O as O well O as O withdrawal O can O also O cause O seizures B-Disease . O Didanosine B-Chemical also O has O a O potential O for O inducing O seizures B-Disease . O However O , O these O other O potential O causes O of O seizure B-Disease were O ruled O out O . O The O time O course O of O events O suggested O that O amphotericin B-Chemical B I-Chemical was O the O cause O of O the O seizures B-Disease in O this O AIDS B-Disease patient O . O CONCLUSIONS O : O Amphotericin B-Chemical B I-Chemical seems O to O be O the O probable O cause O of O the O seizures B-Disease . O To O date O , O only O three O cases O of O seizures B-Disease associated O with O amphotericin B-Chemical B I-Chemical have O been O reported O in O the O literature O , O but O healthcare O providers O should O be O aware O of O the O potential O for O this O rare O adverse O effect O . O Sirolimus B-Chemical and O mycophenolate B-Chemical mofetil I-Chemical for O calcineurin O - O free O immunosuppression O in O renal O transplant O recipients O . O Calcineurin O inhibitors O , O such O as O cyclosporine B-Chemical and O tacrolimus B-Chemical , O have O been O available O for O almost O 20 O years O . O Although O these O drugs O are O highly O effective O and O represent O the O mainstay O of O transplant O immunosuppression O , O they O are O associated O with O acute O and O chronic O nephrotoxicity B-Disease . O Acute O nephrotoxicity B-Disease , O which O occurs O in O the O early O period O after O transplantation O , O leads O to O a O higher O rate O of O dialysis O , O and O chronic O nephrotoxicity B-Disease may O eventually O result O in O graft O loss O . O Acute O and O chronic O nephrotoxicity B-Disease is O becoming O more O common O as O the O use O of O marginal O kidneys O for O transplantation O increases O . O Two O recently O available O immunosuppressive O agents O , O mycophenolate B-Chemical mofetil I-Chemical and O sirolimus B-Chemical ( O rapamycin B-Chemical ) O , O have O no O nephrotoxicity B-Disease . O The O use O of O these O drugs O in O combination O with O other O agents O has O led O to O the O development O of O new O paradigms O of O immunosuppressive O therapy O . O This O paper O reviews O the O results O of O clinical O trials O that O have O investigated O these O new O approaches O to O immunosuppression O in O renal O transplant O recipients O . O Tolerability O of O nimesulide B-Chemical and O paracetamol B-Chemical in O patients O with O NSAID B-Chemical - O induced O urticaria B-Disease / O angioedema B-Disease . O Previous O studies O evaluated O the O tolerance O of O nimesulide B-Chemical and O paracetamol B-Chemical in O subjects O with O cutaneous O , O respiratory O and O anaphylactoid O reactions O induced O by O nonsteroidal B-Chemical anti I-Chemical - I-Chemical inflammatory I-Chemical drugs I-Chemical ( O NSAIDs B-Chemical ) O . O In O this O study O we O investigated O tolerability O and O reliability O of O nimesulide B-Chemical and O paracetamol B-Chemical in O a O very O large O number O of O patients O with O an O exclusive O well O - O documented O history O of O NSAID B-Chemical - O induced O urticaria B-Disease / O angioedema B-Disease . O Furthermore O , O we O evaluated O whether O some O factors O have O the O potential O to O increase O the O risk O of O reaction O to O paracetamol B-Chemical and O nimesulide B-Chemical . O A O single O - O placebo O - O controlled O oral O challenge O procedure O with O nimesulide B-Chemical or O paracetamol B-Chemical was O applied O to O 829 O patients O with O a O history O of O NSAID B-Chemical - O induced O urticaria B-Disease / O angioedema B-Disease . O A O total O of O 75 O / O 829 O ( O 9 O . O 4 O % O ) O patients O experienced O reactions O to O nimesulide B-Chemical or O paracetamol B-Chemical . O Of O the O 715 O patients O tested O with O nimesulide B-Chemical 62 O ( O 8 O . O 6 O % O ) O showed O a O positive O test O , O while O of O 114 O subjects O submitted O to O the O challenge O with O paracetamol B-Chemical , O 13 O ( O 9 O . O 6 O % O ) O did O not O tolerate O this O drug O . O Furthermore O , O 18 O . O 28 O % O of O patients O with O a O history O of O chronic O urticaria B-Disease and O 11 O . O 8 O % O of O subjects O with O an O history O of O NSAID B-Chemical - O induced O urticaria B-Disease / O angioedema B-Disease or O angioedema B-Disease alone O ( O with O or O without O chronic O urticaria B-Disease ) O resulted O to O be O intolerant O to O alternative O drugs O . O Taken O together O , O our O results O confirm O the O good O tolerability O of O nimesulide B-Chemical and O paracetamol B-Chemical in O patients O who O experienced O urticaria B-Disease / O angioedema B-Disease caused O by O NSAIDs B-Chemical . O However O , O the O risk O of O reaction O to O these O alternative O study O drugs O is O statistically O increased O by O a O history O of O chronic O urticaria B-Disease and O , O above O all O , O by O a O history O of O NSAID B-Chemical - O induced O angioedema B-Disease . O Comparison O of O aqueous O and O gellan O ophthalmic O timolol B-Chemical with O placebo O on O the O 24 O - O hour O heart O rate O response O in O patients O on O treatment O for O glaucoma B-Disease . O PURPOSE O : O Topical O beta O - O blocker O treatment O is O routine O therapy O in O the O management O of O patients O with O glaucoma B-Disease . O Therapy O results O in O systemic O absorption O , O however O , O the O degree O of O reduction O of O resting O and O peak O heart O rate O has O not O been O quantified O .

O 001 O ) O , O and O this O reduction O was O most O pronounced O during O the O daytime O ( O - O 7 O . O 5 O % O change O in O mean O heart O rate O , O - O 5 O . O 7 O beats O / O min O ) O . O Timolol B-Chemical gellan O showed O a O numerically O but O not O significantly O smaller O reduction O in O 24 O - O hour O heart O rate O , O compared O with O timolol B-Chemical solution O . O During O the O night O , O the O mean O 12 O - O hour O heart O rate O on O placebo O and O timolol B-Chemical gellan O were O both O significantly O less O than O on O timolol B-Chemical solution O ; O the O difference O between O solution O and O gellan O treatments O was O statistically O significant O ( O P O = O .

O This O response O was O most O pronounced O during O the O active O daytime O period O . O These O data O quantify O the O modest O bradycardia B-Disease associated O with O ophthalmic O beta O - O blocker O therapy O in O a O typical O patient O population O on O therapy O for O glaucoma B-Disease . O Although O exercise O performance O was O not O assessed O in O this O trial O , O reductions O of O this O magnitude O should O not O have O substantial O clinical O consequences O . O Management O strategies O for O ribavirin B-Chemical - O induced O hemolytic B-Disease anemia I-Disease in O the O treatment O of O hepatitis B-Disease C I-Disease : O clinical O and O economic O implications O . O OBJECTIVES O : O Recently O published O studies O have O demonstrated O increased O efficacy O and O cost O - O effectiveness O of O combination O therapy O with O interferon O and O alpha O - O 2b O / O ribavirin B-Chemical compared O with O interferon B-Chemical - I-Chemical alpha I-Chemical monotherapy O in O the O treatment O of O chronic B-Disease hepatitis I-Disease C I-Disease ( O CHC B-Disease ) O . O Combination O therapy O is O associated O with O a O clinically O important O adverse O effect O : O ribavirin B-Chemical - O induced O hemolytic B-Disease anemia I-Disease ( O RIHA B-Disease ) O . O The O objective O of O this O study O was O to O evaluate O the O direct O health O - O care O costs O and O management O of O RIHA B-Disease during O treatment O of O CHC B-Disease in O a O clinical O trial O setting O . O METHODS O : O A O systematic O literature O review O was O conducted O to O synthesize O information O on O the O incidence O and O management O of O RIHA B-Disease . O Decision O - O analytic O techniques O were O used O to O estimate O the O cost O of O treating O RIHA B-Disease . O Uncertainty O was O evaluated O using O sensitivity O analyses O . O RESULTS O : O RIHA B-Disease , O defined O as O a O reduction O in O hemoglobin O to O less O than O 100 O g O / O L O , O occurs O in O approximately O 7 O % O to O 9 O % O of O patients O treated O with O combination O therapy O . O The O standard O of O care O for O management O of O RIHA B-Disease is O reduction O or O discontinuation O of O the O ribavirin B-Chemical dosage O . O We O estimated O the O direct O cost O of O treating O clinically O significant O RIHA B-Disease to O be O 170 O per O patient O receiving O combination O therapy O per O 48 O - O week O treatment O course O ( O range O 68 O - O 692 O ) O . O The O results O of O the O one O - O way O sensitivity O analyses O ranged O from O 57 O to O 317 O . O In O comparison O , O the O cost O of O 48 O weeks O of O combination O therapy O is O 16 O , O 459 O . O CONCLUSIONS O : O The O direct O cost O of O treating O clinically O significant O RIHA B-Disease is O 1 O % O ( O 170 O / O 16 O , O 459 O ) O of O drug O treatment O costs O . O Questions O remain O about O the O optimal O dose O of O ribavirin B-Chemical and O the O incidence O of O RIHA B-Disease in O a O real O - O world O population O . O Despite O these O uncertainties O , O this O initial O evaluation O of O the O direct O cost O of O treating O RIHA B-Disease provides O an O estimate O of O the O cost O and O management O implications O of O this O clinically O important O adverse O effect O . O Preliminary O efficacy O assessment O of O intrathecal O injection O of O an O American O formulation O of O adenosine B-Chemical in O humans O . O BACKGROUND O : O Preclinical O studies O of O intrathecal O adenosine B-Chemical suggest O it O may O be O effective O in O the O treatment O of O acute B-Disease and I-Disease chronic I-Disease pain I-Disease in O humans O , O and O preliminary O studies O in O volunteers O and O patients O with O a O Swedish O formulation O of O adenosine B-Chemical suggests O it O may O be O effective O in O hypersensitivity B-Disease states O but O not O with O acute O noxious O stimulation O . O The O purpose O of O this O study O was O to O screen O for O efficacy O of O a O different O formulation O of O adenosine B-Chemical marketed O in O the O US O , O using O both O acute O noxious O stimulation O and O capsaicin B-Chemical - O evoked O mechanical O hypersensitivity B-Disease . O METHODS O : O Following O Food O and O Drug O Administration O and O institutional O review O board O approval O and O written O informed O consent O , O 65 O volunteers O were O studied O in O two O trials O : O an O open O - O label O , O dose O - O escalating O trial O with O intrathecal O adenosine B-Chemical doses O of O 0 O . O 25 O - O 2 O . O 0 O mg O and O a O double O - O blind O , O placebo O - O controlled O trial O of O adenosine B-Chemical , O 2 O mg O . O Cerebrospinal O fluid O was O obtained O for O pharmacokinetic O analysis O , O and O pain B-Disease ratings O in O response O to O acute O heat O stimuli O and O areas O of O mechanical B-Disease hyperalgesia I-Disease and O allodynia B-Disease after O intradermal O capsaicin B-Chemical injection O were O determined O . O RESULTS O : O Adenosine B-Chemical produced O no O effect O on O pain B-Disease report O to O acute O noxious O thermal O or O chemical O stimulation O but O reduced O mechanical B-Disease hyperalgesia I-Disease and O allodynia B-Disease from O intradermal O capsaicin B-Chemical injection O for O at O least O 24 O h O . O In O contrast O , O residence O time O of O adenosine B-Chemical in O cerebrospinal O fluid O was O short O ( O < O 4 O h O ) O . O CONCLUSIONS O : O These O results O show O selective O inhibition O by O intrathecal O adenosine B-Chemical of O hypersensitivity B-Disease , O presumed O to O reflect O central O sensitization O in O humans O after O peripheral O capsaicin B-Chemical injection O . O The O long O - O lasting O effect O is O consistent O with O that O observed O in O preliminary O reports O of O patients O with O chronic O neuropathic B-Disease pain I-Disease and O is O not O due O to O prolonged O residence O of O adenosine B-Chemical in O cerebrospinal O fluid O . O Delayed O - O onset O heparin B-Chemical - O induced O thrombocytopenia B-Disease . O BACKGROUND O : O Heparin B-Chemical - O induced O thrombocytopenia B-Disease presents O 5 O to O 12 O days O after O heparin B-Chemical exposure O , O with O or O without O arterial B-Disease or I-Disease venous I-Disease thromboemboli I-Disease . O Delayed O recognition O and O treatment O of O heparin B-Chemical - O induced O thrombocytopenia B-Disease contribute O to O poor O patient O outcomes O . O OBJECTIVE O : O To O describe O and O increase O awareness O of O a O clinical O scenario O in O which O the O onset O or O manifestations O of O heparin B-Chemical - O induced O thrombocytopenia B-Disease are O delayed O . O DESIGN O : O Retrospective O case O series O . O SETTING O : O Three O large O urban O hospitals O ( O with O active O cardiovascular O surgery O programs O ) O . O PATIENTS O : O 14 O patients O seen O over O a O 3 O - O year O period O in O whom O heparin B-Chemical - O induced O thrombocytopenia B-Disease became O apparent O on O delayed O presentation O with O thromboembolic B-Disease complications O . O MEASUREMENTS O : O Platelet O counts O , O onset O of O objectively O determined O thromboembolism B-Disease , O results O of O heparin B-Chemical - O induced O platelet O factor O 4 O antibody O tests O , O and O outcomes O . O RESULTS O : O Patients O went O home O after O hospitalizations O that O had O included O heparin B-Chemical exposure O - O - O in O most O cases O , O with O no O thrombocytopenia B-Disease recognized O - O - O only O to O return O to O the O hospital O ( O median O , O day O 14 O ) O with O thromboembolic B-Disease complications O . O Thromboemboli B-Disease were O venous O ( O 12 O patients O , O 7 O with O pulmonary B-Disease emboli I-Disease ) O or O arterial O ( O 4 O patients O ) O or O both O . O Platelet O counts O were O mildly O decreased O in O all O but O 2 O patients O on O second O presentation O . O On O readmission O , O 11 O patients O received O therapeutic O heparin B-Chemical , O which O worsened O the O patients O ' O clinical O condition O and O , O in O all O 11 O cases O , O decreased O the O platelet O count O ( O mean O at O readmission O , O 143 O x O 10 O ( O 9 O ) O cells O / O L O ; O mean O nadir O after O heparin B-Chemical re O - O exposure O , O 39 O x O 10 O ( O 9 O ) O cells O / O L O ) O . O Results O of O serologic O tests O for O heparin B-Chemical - O induced O antibodies O were O positive O in O all O patients O . O Subsequent O treatments O included O alternative O anticoagulants O ( O 11 O patients O ) O , O thrombolytic O drugs O ( O 3 O patients O ) O , O inferior O vena O cava O filters O ( O 3 O patients O ) O and O , O eventually O , O warfarin B-Chemical ( O 11 O patients O ) O . O Three O patients O died O . O CONCLUSIONS O : O Delayed O - O onset O heparin B-Chemical - O induced O thrombocytopenia B-Disease is O increasingly O being O recognized O . O To O avoid O disastrous O outcomes O , O physicians O must O consider O heparin B-Chemical - O induced O thrombocytopenia B-Disease whenever O a O recently O hospitalized O patient O returns O with O thromboembolism B-Disease ; O therapy O with O alternative O anticoagulants O , O not O heparin B-Chemical , O should O be O initiated O . O Treatment O of O risperidone B-Chemical - O induced O hyperprolactinemia B-Disease with O a O dopamine B-Chemical agonist O in O children O . O BACKGROUND O : O Risperidone B-Chemical , O a O potent O antagonist O of O both O serotonergic O ( O 5HT2A O ) O and O dopaminergic O D2 O receptors O is O associated O with O hyperprolactinemia B-Disease in O adults O and O children O . O Chronically O elevated O prolactin O levels O in O children O with O prolactinomas B-Disease may O be O associated O with O arrested O growth O and O development O resulting O in O either O delayed B-Disease puberty I-Disease or O short O stature O . O These O possibilities O stress O the O importance O of O developing O a O safe O and O effective O approach O to O drug O - O induced O hyperprolactinemia B-Disease in O youth O . O We O report O the O successful O treatment O of O risperidone B-Chemical - O induced O hyperprolactinemia B-Disease with O cabergoline B-Chemical in O youth O . O METHODS O : O We O undertook O a O retrospective O case O review O of O four O children O with O risperidone B-Chemical - O induced O hyperprolactinemia B-Disease treated O with O cabergoline B-Chemical . O RESULTS O : O Four O males O ( O age O 6 O - O 11 O years O ) O with O Diagnostic O and O Statistical O Manual O of O Mental B-Disease Disorders I-Disease ( O fourth O edition O ) O bipolar B-Disease disorder I-Disease or O psychoses B-Disease , O with O risperidone B-Chemical - O induced O elevations O in O serum O prolactin O levels O ( O 57 O . O 5 O - O 129 O ng O / O mL O , O normal O 5 O - O 15 O ng O / O mL O ) O , O were O treated O with O cabergoline B-Chemical ( O mean O dose O 2 O . O 13 O + O / O - O 0 O . O 09 O mg O / O week O ) O . O When O serum O prolactin O levels O normalized O in O all O four O subjects O ( O mean O 11 O . O 2 O + O / O - O 10 O . O 9 O ng O / O mL O ) O , O the O cabergoline B-Chemical dose O was O reduced O to O 1 O mg O / O week O in O three O of O four O subjects O . O The O mean O duration O of O therapy O with O cabergoline B-Chemical was O 523 O . O 5 O + O / O - O 129 O . O 7 O days O , O and O the O mean O duration O of O therapy O with O risperidone B-Chemical was O 788 O . O 5 O + O / O - O 162 O . O 5 O days O . O Cabergoline B-Chemical was O well O tolerated O without O adverse O effects O . O CONCLUSIONS O : O Cabergoline B-Chemical may O be O useful O for O the O treatment O of O risperidone B-Chemical - O induced O hyperprolactinemia B-Disease in O youth O ; O however O , O further O research O is O needed O . O Acute O cholestatic B-Disease hepatitis I-Disease after O exposure O to O isoflurane B-Chemical . O OBJECTIVE O : O To O report O a O case O of O acute O cholestatic B-Disease hepatitis I-Disease following O exposure O to O the O inhalational O anesthetic O isoflurane B-Chemical . O CASE O SUMMARY O : O A O 70 O - O year O - O old O healthy O woman O from O Iraq O developed O acute O cholestatic B-Disease hepatitis I-Disease 3 O weeks O following O repair O of O the O right O rotator O cuff O under O general O anesthesia O . O There O was O no O evidence O for O viral O , O autoimmune O , O or O metabolic O causes O of O hepatitis B-Disease . O No O other O medications O were O involved O except O for O dipyrone B-Chemical for O analgesia B-Disease . O The O alanine B-Chemical aminotransferase O was O elevated O to O a O peak O concentration O of O 1533 O U O / O L O and O the O serum O bilirubin B-Chemical reached O a O peak O of O 17 O . O 0 O mg O / O dL O . O There O was O slow O improvement O over O 4 O months O . O Accidental O reexposure O by O the O patient O to O dipyrone B-Chemical was O uneventful O . O DISCUSSION O : O The O clinical O and O histologic O picture O of O this O case O resembles O halothane B-Disease hepatitis I-Disease , O which O has O a O significant O mortality O rate O . O CONCLUSIONS O : O Isoflurane B-Chemical , O a O common O anesthetic O agent O , O can O cause O severe O cholestatic B-Disease hepatitis I-Disease . O Torsade B-Disease de I-Disease pointes I-Disease induced O by O metoclopramide B-Chemical in O an O elderly O woman O with O preexisting O complete O left B-Disease bundle I-Disease branch I-Disease block I-Disease . O There O is O a O growing O list O of O drugs O implicated O in O acquired O long B-Disease QT I-Disease syndrome I-Disease and O torsade B-Disease de I-Disease pointes I-Disease . O However O , O the O torsadogenic O potential O of O metoclopramide B-Chemical , O a O commonly O used O antiemetic O and O prokinetic O drug O , O has O not O been O reported O in O the O literature O , O despite O its O chemical O similarity O to O procainamide B-Chemical . O We O report O on O a O 92 O - O year O - O old O woman O with O preexisting O complete O left B-Disease bundle I-Disease branch I-Disease block I-Disease who O developed O torsade B-Disease de I-Disease pointes I-Disease after O intravenous O and O oral O administration O of O metoclopramide B-Chemical . O This O patient O also O developed O torsade B-Disease de I-Disease pointes I-Disease when O cisapride B-Chemical and O erythromycin B-Chemical were O given O simultaneously O . O These O two O episodes O were O suppressed O successfully O after O discontinuing O the O offending O drugs O and O administering O class O IB O drugs O . O This O is O the O first O documentation O that O metoclopramide B-Chemical provokes O torsade B-Disease de I-Disease pointes I-Disease clinically O . O Metoclopramide B-Chemical should O be O used O cautiously O in O patients O with O a O risk O of O torsade B-Disease de I-Disease pointes I-Disease . O Dopamine B-Chemical D2 O receptor O signaling O controls O neuronal O cell O death O induced O by O muscarinic O and O glutamatergic O drugs O . O Dopamine B-Chemical ( O DA B-Chemical ) O , O through O D1 O / O D2 O receptor O - O mediated O signaling O , O plays O a O major O role O in O the O control O of O epileptic B-Disease seizures I-Disease arising O in O the O limbic O system O . O Excitotoxicity B-Disease leading O to O neuronal O cell O death O in O the O affected O areas O is O a O major O consequence O of O seizures B-Disease at O the O cellular O level O . O In O this O respect O , O little O is O known O about O the O role O of O DA B-Chemical receptors O in O the O occurrence O of O epilepsy B-Disease - O induced O neuronal O cell O death O . O Here O we O analyze O the O occurrence O of O seizures B-Disease and O neurotoxicity B-Disease in O D2R O - O / O - O mice O treated O with O the O cholinergic O agonist O pilocarpine B-Chemical . O We O compared O these O results O with O those O previously O obtained O with O kainic B-Chemical acid I-Chemical ( O KA B-Chemical ) O , O a O potent O glutamate B-Chemical agonist O . O Importantly O , O D2R O - O / O - O mice O develop O seizures B-Disease at O doses O of O both O drugs O that O are O not O epileptogenic O for O WT O littermates O and O show O greater O neurotoxicity B-Disease . O However O , O pilocarpine B-Chemical - O induced O seizures B-Disease result O in O a O more O widespread O neuronal O death O in O both O WT O and O D2R O - O / O - O brains O in O comparison O to O KA B-Chemical . O Thus O , O the O absence O of O D2R O lowers O the O threshold O for O seizures B-Disease induced O by O both O glutamate B-Chemical and O acetylcholine B-Chemical . O Moreover O , O the O dopaminergic O control O of O epilepsy B-Disease - O induced O neurodegeneration B-Disease seems O to O be O mediated O by O distinct O interactions O of O D2R O signaling O with O these O two O neurotransmitters O . O Steroid B-Chemical structure O and O pharmacological O properties O determine O the O anti O - O amnesic B-Disease effects O of O pregnenolone B-Chemical sulphate I-Chemical in O the O passive O avoidance O task O in O rats O . O Pregnenolone B-Chemical sulphate I-Chemical ( O PREGS B-Chemical ) O has O generated O interest O as O one O of O the O most O potent O memory O - O enhancing O neurosteroids O to O be O examined O in O rodent O learning O studies O , O with O particular O importance O in O the O ageing O process O . O The O mechanism O by O which O this O endogenous O steroid B-Chemical enhances O memory O formation O is O hypothesized O to O involve O actions O on O glutamatergic O and O GABAergic O systems O . O This O hypothesis O stems O from O findings O that O PREGS B-Chemical is O a O potent O positive O modulator O of O N B-Chemical - I-Chemical methyl I-Chemical - I-Chemical d I-Chemical - I-Chemical aspartate I-Chemical receptors O ( O NMDARs O ) O and O a O negative O modulator O of O gamma B-Chemical - I-Chemical aminobutyric I-Chemical acid I-Chemical ( O A O ) O receptors O ( O GABA B-Chemical ( O A O ) O Rs O ) O . O Moreover O , O PREGS B-Chemical is O able O to O reverse O the O amnesic B-Disease - O like O effects O of O NMDAR O and O GABA B-Chemical ( O A O ) O R O ligands O . O To O investigate O this O hypothesis O , O the O present O study O in O rats O examined O the O memory O - O altering O abilities O of O structural O analogs O of O PREGS B-Chemical , O which O differ O in O their O modulation O of O NMDAR O and O / O or O GABA B-Chemical ( O A O ) O R O function O . O The O analogs O tested O were O : O 11 B-Chemical - I-Chemical ketopregnenolone I-Chemical sulphate I-Chemical ( O an O agent O that O is O inactive O at O GABA B-Chemical ( O A O ) O Rs O and O NMDARs O ) O , O epipregnanolone B-Chemical ( I-Chemical [ I-Chemical 3beta I-Chemical - I-Chemical hydroxy I-Chemical - I-Chemical 5beta I-Chemical - I-Chemical pregnan I-Chemical - I-Chemical 20 I-Chemical - I-Chemical one I-Chemical ] I-Chemical sulphate I-Chemical , O an O inhibitor O of O both O GABA B-Chemical ( O A O ) O Rs O and O NMDARs O ) O , O and O a O newly O synthesized O ( O - O ) O PREGS B-Chemical enantiomer O ( O which O is O identical O to O PREGS B-Chemical in O effects O on O GABA B-Chemical ( O A O ) O Rs O and O NMDARs O ) O . O The O memory O - O enhancing O effects O of O PREGS B-Chemical and O its O analogs O were O tested O in O the O passive O avoidance O task O using O the O model O of O scopolamine B-Chemical - O induced O amnesia B-Disease . O Both O PREGS B-Chemical and O its O ( O - O ) O enantiomer O blocked O the O effects O of O scopolamine B-Chemical . O The O results O show O that O , O unlike O PREGS B-Chemical , O 11 B-Chemical - I-Chemical ketopregnenolone I-Chemical sulphate I-Chemical and O epipregnanolone B-Chemical sulphate I-Chemical failed O to O block O the O effect O of O scopolamine B-Chemical , O suggesting O that O altering O the O modulation O of O NMDA B-Chemical receptors O diminishes O the O memory O - O enhancing O effects O of O PREGS B-Chemical . O Moreover O , O enantioselectivity O was O demonstrated O by O the O ability O of O natural O PREGS B-Chemical to O be O an O order O of O magnitude O more O effective O than O its O synthetic O enantiomer O in O reversing O scopolamine B-Chemical - O induced O amnesia B-Disease . O These O results O identify O a O novel O neuropharmacological O site O for O the O modulation O of O memory O processes O by O neuroactive O steroids B-Chemical . O Activation O of O poly B-Chemical ( I-Chemical ADP I-Chemical - I-Chemical ribose I-Chemical ) I-Chemical polymerase O contributes O to O development O of O doxorubicin B-Chemical - O induced O heart B-Disease failure I-Disease . O Activation O of O the O nuclear O enzyme O poly B-Chemical ( I-Chemical ADP I-Chemical - I-Chemical ribose I-Chemical ) I-Chemical polymerase O ( O PARP O ) O by O oxidant O - O mediated O DNA O damage O is O an O important O pathway O of O cell O dysfunction O and O tissue O injury O in O conditions O associated O with O oxidative O stress O . O Increased O oxidative O stress O is O a O major O factor O implicated O in O the O cardiotoxicity B-Disease of O doxorubicin B-Chemical ( O DOX B-Chemical ) O , O a O widely O used O antitumor O anthracycline B-Chemical antibiotic O . O Thus O , O we O hypothesized O that O the O activation O of O PARP O may O contribute O to O the O DOX B-Chemical - O induced O cardiotoxicity B-Disease . O Using O a O dual O approach O of O PARP O - O 1 O suppression O , O by O genetic O deletion O or O pharmacological O inhibition O with O the O phenanthridinone O PARP O inhibitor O PJ34 B-Chemical , O we O now O demonstrate O the O role O of O PARP O in O the O development O of O cardiac B-Disease dysfunction I-Disease induced O by O DOX B-Chemical . O PARP O - O 1 O + O / O + O and O PARP O - O 1 O - O / O - O mice O received O a O single O injection O of O DOX B-Chemical ( O 25 O mg O / O kg O i O . O p O ) O . O Five O days O after O DOX B-Chemical administration O , O left O ventricular O performance O was O significantly O depressed O in O PARP O - O 1 O + O / O + O mice O , O but O only O to O a O smaller O extent O in O PARP O - O 1 O - O / O - O ones O . O Similar O experiments O were O conducted O in O BALB O / O c O mice O treated O with O PJ34 B-Chemical or O vehicle O . O Treatment O with O a O PJ34 B-Chemical significantly O improved O cardiac B-Disease dysfunction I-Disease and O increased O the O survival O of O the O animals O . O In O addition O PJ34 B-Chemical significantly O reduced O the O DOX B-Chemical - O induced O increase O in O the O serum O lactate B-Chemical dehydrogenase O and O creatine B-Chemical kinase O activities O but O not O metalloproteinase O activation O in O the O heart O . O Thus O , O PARP O activation O contributes O to O the O cardiotoxicity B-Disease of O DOX B-Chemical . O PARP O inhibitors O may O exert O protective O effects O against O the O development O of O severe O cardiac B-Disease complications I-Disease associated O with O the O DOX B-Chemical treatment O . O Spironolactone B-Chemical : O is O it O a O novel O drug O for O the O prevention O of O amphotericin B-Chemical B I-Chemical - O related O hypokalemia B-Disease in O cancer B-Disease patients O ? O OBJECTIVE O : O Nephrotoxicity B-Disease is O the O major O adverse O effect O of O amphotericin B-Chemical B I-Chemical ( O AmB B-Chemical ) O , O often O limiting O administration O of O full O dosage O . O Selective O distal O tubular O epithelial O toxicity B-Disease seems O to O be O responsible O for O the O profound O potassium B-Chemical wasting O that O is O a O major O clinical O side O effect O of O treatment O with O AmB B-Chemical . O Potassium B-Chemical depletion O also O potentiates O the O tubular O toxicity B-Disease of O AmB B-Chemical . O This O study O was O designed O to O assess O the O ability O of O spironolactone B-Chemical to O reduce O potassium B-Chemical requirements O and O to O prevent O hypokalemia B-Disease in O neutropenic B-Disease patients O on O AmB B-Chemical treatment O . O METHODS O : O In O this O study O 26 O patients O with O various O hematological B-Disease disorders I-Disease were O randomized O to O receive O either O intravenous O AmB B-Chemical alone O or O AmB B-Chemical and O oral O spironolactone B-Chemical 100 O mg O twice O daily O when O developing O a O proven O or O suspected O fungal B-Disease infection I-Disease . O RESULTS O : O Patients O receiving O concomitant O AmB B-Chemical and O spironolactone B-Chemical had O significantly O higher O plasma O potassium B-Chemical levels O than O those O receiving O AmB B-Chemical alone O ( O P O = O 0 O . O 0027 O ) O . O Those O patients O receiving O AmB B-Chemical and O spironolactone B-Chemical required O significantly O less O potassium B-Chemical supplementation O to O maintain O their O plasma O potassium B-Chemical within O the O normal O range O ( O P O = O 0 O . O 022 O ) O . O Moreover O , O urinary O potassium B-Chemical losses O were O significantly O less O in O patients O receiving O AmB B-Chemical and O spironolactone B-Chemical than O those O receiving O AmB B-Chemical alone O ( O P O = O 0 O . O 040 O ) O . O CONCLUSION O : O This O study O showed O that O spironolactone B-Chemical can O reduce O potassium B-Chemical requirements O and O prevent O hypokalemia B-Disease by O reducing O urinary O potassium B-Chemical loss O in O neutropenic B-Disease patients O on O AmB B-Chemical treatment O . O Erectile B-Disease dysfunction I-Disease occurs O following O substantia O nigra O lesions O in O the O rat O . O Erectile O function O was O assessed O 6 O weeks O following O uni O - O and O bilateral O injections O of O 6 B-Chemical - I-Chemical hydroxydopamine I-Chemical in O the O substantia O nigra O nucleus O of O the O brain O . O Behavioral O apomorphine B-Chemical - O induced O penile O erections O were O reduced O ( O 5 O / O 8 O ) O and O increased O ( O 3 O / O 8 O ) O in O uni O - O and O bilateral O lesioned O animals O .

O Morphine B-Chemical but O not O nicotine B-Chemical induced O a O dose O - O dependent O catalepsy B-Disease . O The O response O of O morphine B-Chemical was O potentiated O by O nicotine B-Chemical . O Intraperitoneal O administration O of O atropine B-Chemical , O naloxone B-Chemical , O mecamylamine B-Chemical , O and O hexamethonium B-Chemical to O mice O reduced O catalepsy B-Disease induced O by O a O combination O of O morphine B-Chemical with O nicotine B-Chemical . O Intracerebroventricular O injection O of O atropine B-Chemical , O hexamethonium B-Chemical , O and O naloxone B-Chemical also O decreased O catalepsy B-Disease induced O by O morphine B-Chemical plus O nicotine B-Chemical . O Intraperitoneal O administration O of O atropine B-Chemical , O but O not O intraperitoneal O or O intracerebroventricular O injection O of O hexamethonium B-Chemical , O decreased O the O effect O of O a O single O dose O of O morphine B-Chemical . O It O was O concluded O that O morphine B-Chemical catalepsy B-Disease can O be O elicited O by O opioid O and O cholinergic O receptors O , O and O the O potentiation O of O morphine B-Chemical induced O by O nicotine B-Chemical may O also O be O mediated O through O cholinergic O receptor O mechanisms O . O Force O overflow O and O levodopa B-Chemical - O induced O dyskinesias B-Disease in O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease . O We O assessed O force O coordination O of O the O hand O in O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease and O its O relationship O to O motor O complications O of O levodopa B-Chemical therapy O , O particularly O to O levodopa B-Chemical - O induced O dyskinesias B-Disease ( O LID B-Disease ) O . O We O studied O two O groups O of O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease patients O with O ( O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease + O LID B-Disease , O n O = O 23 O ) O and O without O levodopa B-Chemical - O induced O dyskinesias B-Disease ( O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease - O LID B-Disease , O n O = O 10 O ) O , O and O age O - O matched O healthy O controls O . O The O motor O score O of O the O Unified O Parkinson B-Disease ' I-Disease s I-Disease Disease I-Disease Rating O Scale O , O a O dyskinesia B-Disease score O and O force O in O a O grip O - O lift O paradigm O were O assessed O ON O and O OFF O levodopa B-Chemical . O A O pathological O increase O of O forces O was O seen O in O ON O - O state O in O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease + O LID B-Disease only O . O In O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease + O LID B-Disease , O the O force O involved O in O pressing O down O the O object O before O lifting O was O significantly O increased O by O levodopa B-Chemical ( O by O 61 O % O , O P O < O 0 O .

O In O contrast O , O no O excessive O force O was O found O in O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease - O LID B-Disease . O Peak O grip O force O in O ON O - O state O was O 140 O % O ( O P O < O 0 O .

O 01 O ) O between O groups O . O Severity O of O peak O - O dose O dyskinesias B-Disease was O strongly O correlated O with O grip O force O in O ON O - O state O ( O r O = O 0 O . O 79 O with O peak O force O , O P O < O 0 O . O 01 O ) O . O No O correlation O was O observed O between O forces O and O the O motor O score O as O well O as O with O the O daily O dose O of O dopaminergic O medication O . O Force O excess O was O only O observed O in O patients O with O LID B-Disease and O motor O fluctuations O . O A O close O relationship O was O seen O between O the O overshooting O of O forces O and O dyskinesias B-Disease in O the O ON O - O drug O condition O . O We O postulate O that O both O LID B-Disease and O grip O force O excess O share O common O pathophysiological O mechanisms O related O to O motor O fluctuations O . O Behavioral O effects O of O MK B-Chemical - I-Chemical 801 I-Chemical on O reserpine B-Chemical - O treated O mice O . O The O effects O of O dizocilpine B-Chemical ( O MK B-Chemical - I-Chemical 801 I-Chemical ) O , O a O noncompetitive O N B-Chemical - I-Chemical methyl I-Chemical - I-Chemical D I-Chemical - I-Chemical aspartate I-Chemical ( O NMDA B-Chemical ) O receptor O antagonist O , O were O studied O on O dopamine B-Chemical - O related O behaviors O induced O by O reserpine B-Chemical treatments O . O This O study O focuses O on O behavioral O syndromes O that O may O used O as O models O for O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease , O or O tardive B-Disease dyskinesia I-Disease , O and O its O response O after O glutamatergic O blockage O . O Reserpine B-Chemical ( O 1 O mg O / O kg O ) O , O administered O once O every O other O day O for O 4 O days O , O produced O increases O in O orofacial B-Disease dyskinesia I-Disease , O tongue O protrusion O and O vacuous O chewing O in O mice O , O which O are O signs O indicative O of O tardive B-Disease dyskinesia I-Disease . O Reserpine B-Chemical also O produced O tremor B-Disease and O catalepsy B-Disease , O which O are O signs O suggestive O of O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease . O MK B-Chemical - I-Chemical 801 I-Chemical ( O 0 O . O 1 O mg O / O kg O ) O , O administered O 30 O min O before O the O observation O test O , O prevented O the O vacuous O chewing O movements O , O tongue O protrusions O and O catalepsy B-Disease induced O by O reserpine B-Chemical . O However O , O MK B-Chemical - I-Chemical 801 I-Chemical injection O produced O a O significant O increase O of O tremor B-Disease in O reserpine B-Chemical - O treated O mice O . O Reserpine B-Chemical ( O 1 O mg O / O kg O ) O , O administered O 90 O min O before O the O test O and O followed O by O apomophine B-Chemical injection O ( O 0 O . O 1 O mg O / O kg O ) O 5 O min O before O the O test O , O did O not O produce O oral B-Disease dyskinesia I-Disease in O mice O . O On O the O other O hand O , O reserpine B-Chemical induced O increases O in O tremor B-Disease and O catalepsy B-Disease compared O to O control O mice O . O MK B-Chemical - I-Chemical 801 I-Chemical ( O 0 O . O 1 O mg O / O kg O ) O administration O attenuated O the O catalepsy B-Disease and O tremor B-Disease induced O by O reserpine B-Chemical . O Pretreatment O with O reserpine B-Chemical ( O 1 O mg O / O kg O ) O 24 O h O before O the O observation O test O produced O increases O in O vacuous O chewing O movements O and O tongue O protrusion O , O as O well O as O increases O in O tremor B-Disease and O catalepsy B-Disease , O whereas O MK B-Chemical - I-Chemical 801 I-Chemical ( O 0 O . O 1 O mg O / O kg O ) O injection O 90 O min O before O the O test O reversed O the O effects O of O reserpine B-Chemical . O These O results O show O that O reserpine B-Chemical produces O different O and O abnormal B-Disease movements I-Disease , O which O are O related O to O dose O and O schedule O employed O and O can O be O considered O as O parkinsonian B-Disease - O like O and O tardive B-Disease dsykinesia I-Disease signs O . O The O glutamatergic O blockage O produced O by O NMDA B-Chemical can O restore O these O signs O , O such O as O vacuous O chewing O movements O , O tongue O protrusions O , O catalepsy B-Disease and O tremor B-Disease according O to O the O employed O model O . O Risperidone B-Chemical - O associated O , O benign O transient O visual B-Disease disturbances I-Disease in O schizophrenic B-Disease patients O with O a O past O history O of O LSD B-Chemical abuse O . O Two O schizophrenic B-Disease patients O , O who O had O a O prior O history O of O LSD B-Chemical abuse O and O who O had O previously O developed O EPS B-Disease with O classic O antipsychotics O , O were O successfully O treated O with O risperidone B-Chemical . O They O both O reported O short O episodes O of O transient O visual B-Disease disturbances I-Disease , O which O appeared O immediately O after O starting O treatment O with O risperidone B-Chemical . O This O imagery O resembled O visual B-Disease disturbances I-Disease previously O experienced O as O " O flashbacks O " O related O to O prior O LSD B-Chemical consumption O . O Risperidone B-Chemical administration O was O continued O and O the O visual B-Disease disturbances I-Disease gradually O wore O off O . O During O a O six O - O month O follow O - O up O period O , O there O was O no O recurrence O of O visual B-Disease disturbances I-Disease . O This O phenomenon O may O be O interpreted O as O a O benign O , O short O - O term O and O self O - O limiting O side O effect O which O does O not O contraindicate O the O use O of O risperidone B-Chemical or O interfere O with O treatment O . O Conclusions O based O on O two O case O reports O should O be O taken O with O appropriate O caution O . O Topiramate B-Chemical - O induced O nephrolithiasis B-Disease . O Topiramate B-Chemical is O a O recently O developed O antiepileptic O medication O that O is O becoming O more O widely O prescribed O because O of O its O efficacy O in O treating O refractory B-Disease seizures I-Disease . O Urologists O should O be O aware O that O this O medication O can O cause O metabolic B-Disease acidosis I-Disease in O patients O secondary O to O inhibition O of O carbonic O anhydrase O . O In O addition O , O a O distal O tubular O acidification O defect O may O result O , O thus O impairing O the O normal O compensatory O drop O in O urine O pH O . O These O factors O can O lead O to O the O development O of O calcium B-Chemical phosphate I-Chemical nephrolithiasis B-Disease . O We O report O the O first O two O cases O of O topiramate B-Chemical - O induced O nephrolithiasis B-Disease in O the O urologic O literature O . O Ketamine B-Chemical in O war O / O tropical O surgery O ( O a O final O tribute O to O the O racemic O mixture O ) O . O A O technique O of O continuous O intravenous O anaesthesia O with O ketamine B-Chemical was O used O successfully O during O the O Somalia O civil O war O in O 1994 O and O in O north O Uganda O in O 1999 O for O 64 O operations O in O 62 O patients O , O aged O from O 6 O weeks O to O 70 O years O , O undergoing O limb O and O abdominal O surgery O including O caesarian O sections O and O interventions O in O neonates O . O Operations O lasting O up O to O 2h O could O be O performed O in O the O absence O of O sophisticated O equipment O such O as O pulse O oximeters O or O ventilators O in O patients O on O spontaneous O ventilation O breathing O air O / O oxygen B-Chemical only O . O After O premedication O with O diazepam B-Chemical , O glycopyrrolate B-Chemical and O local O anaesthesia O , O and O induction O with O standard O doses O of O ketamine B-Chemical , O a O maintenance O dose O of O 10 O - O 20 O microg O / O kg O / O min O of O ketamine B-Chemical proved O safe O and O effective O . O Emphasis O was O placed O on O bedside O clinical O monitoring O , O relying O heavily O on O the O heart O rate O . O Diazepam B-Chemical , O unless O contraindicated O or O risky O , O remains O the O only O necessary O complementary O drug O to O ketamine B-Chemical as O it O buffers O its O cardiovascular O response O and O decreases O the O duration O and O intensity O of O operative O and O postoperative O hallucinations B-Disease . O Local O anaesthetic O blocks O were O useful O in O decreasing O the O requirement O for O postoperative O analgesia B-Disease . O An O antisialogue O was O usually O unnecessary O in O operations O lasting O up O to O 2 O h O , O glycopyrrolate B-Chemical being O the O best O choice O for O its O lowest O psychotropic O and O chronotropic O effects O , O especially O in O a O hot O climate O . O Experience O in O war O / O tropical O settings O suggests O this O technique O could O be O useful O in O civilian O contexts O such O as O outdoor O life O - O saving O emergency O surgery O or O in O mass O casualties O where O , O e O . O g O . O amputation O and O rapid O extrication O were O required O . O Intravenous O ribavirin B-Chemical treatment O for O severe O adenovirus B-Disease disease I-Disease in O immunocompromised O children O . O BACKGROUND O : O Adenovirus O is O an O important O cause O of O morbidity O and O mortality O in O the O immunocompromised O host O . O The O incidence O of O severe O adenovirus B-Disease disease I-Disease in O pediatrics O is O increasing O in O association O with O growing O numbers O of O immunocompromised O children O , O where O case O fatality O rates O as O high O as O 50 O % O to O 80 O % O have O been O reported O . O There O are O no O approved O antiviral O agents O with O proven O efficacy O for O the O treatment O of O severe O adenovirus B-Disease disease I-Disease , O nor O are O there O any O prospective O randomized O , O controlled O trials O of O potentially O useful O anti O - O adenovirus O therapies O . O Apparent O clinical O success O in O the O treatment O of O severe O adenovirus B-Disease disease I-Disease is O limited O to O a O few O case O reports O and O small O series O . O Experience O is O greatest O with O intravenous O ribavirin B-Chemical and O cidofovir B-Chemical . O Ribavirin B-Chemical , O a O guanosine B-Chemical analogue O , O has O broad O antiviral O activity O against O both O RNA O and O DNA O viruses O , O including O documented O activity O against O adenovirus O in O vitro O . O Ribavirin B-Chemical is O licensed O in O aerosol O form O for O the O treatment O of O respiratory B-Disease syncytial I-Disease virus I-Disease infection I-Disease , O and O orally O in O combination O with O interferon O to O treat O hepatitis B-Disease C I-Disease . O Intravenous O ribavirin B-Chemical is O the O treatment O of O choice O for O infection B-Disease with I-Disease hemorrhagic I-Disease fever I-Disease viruses I-Disease . O The O most O common O adverse O effect O of O intravenous O ribavirin B-Chemical is O reversible O mild O anemia B-Disease . O The O use O of O cidofovir B-Chemical in O severe O adenovirus B-Disease infection I-Disease has O been O limited O by O adverse O effects O , O the O most O significant O of O which O is O nephrotoxicity B-Disease . O OBJECTIVE O : O We O report O our O experience O with O intravenous O ribavirin B-Chemical therapy O for O severe O adenovirus B-Disease disease I-Disease in O a O series O of O immunocompromised O children O and O review O the O literature O . O DESIGN O / O METHODS O : O We O retrospectively O reviewed O the O medical O records O of O 5 O children O treated O with O intravenous O ribavirin B-Chemical for O documented O severe O adenovirus B-Disease disease I-Disease . O Two O patients O developed O adenovirus O hemorrhagic B-Disease cystitis I-Disease after O cardiac O and O bone O marrow O transplants O , O respectively O . O The O bone O marrow O transplant O patient O also O received O intravenous O cidofovir B-Chemical for O progressive O disseminated O disease O . O An O additional O 3 O children O developed O adenovirus B-Disease pneumonia I-Disease ; O 2 O were O neonates O , O 1 O of O whom O had O partial O DiGeorge B-Disease syndrome I-Disease . O The O remaining O infant O had O recently O undergone O a O cardiac O transplant O . O Intravenous O ribavirin B-Chemical was O administered O on O a O compassionate O - O use O protocol O . O RESULTS O : O Complete O clinical O recovery O followed O later O by O viral O clearance O was O observed O in O 2 O children O : O the O cardiac O transplant O recipient O with O adenovirus O hemorrhagic B-Disease cystitis I-Disease and O the O immunocompetent O neonate O with O adenovirus B-Disease pneumonia I-Disease . O The O remaining O 3 O children O died O of O adenovirus B-Disease disease I-Disease . O Intravenous O ribavirin B-Chemical therapy O was O well O tolerated O . O Use O of O cidofovir B-Chemical in O 1 O child O was O associated O with O progressive B-Disease renal I-Disease failure I-Disease and O neutropenia B-Disease . O DISCUSSION O : O Our O series O of O patients O is O representative O of O the O spectrum O of O immunocompromised O children O at O greatest O risk O for O severe O adenovirus B-Disease disease I-Disease , O namely O solid O - O organ O and O bone O marrow O transplant O recipients O , O neonates O , O and O children O with O immunodeficiency B-Disease . O Although O intravenous O ribavirin B-Chemical was O not O effective O for O all O children O with O severe O adenovirus B-Disease disease I-Disease in O this O series O or O in O the O literature O , O therapy O is O unlikely O to O be O of O benefit O if O begun O late O in O the O course O of O the O infection B-Disease . O Early O identification O , O eg O by O polymerase O chain O reaction O of O those O patients O at O risk O of O disseminated O adenovirus B-Disease disease I-Disease may O permit O earlier O antiviral O treatment O and O better O evaluation O of O therapeutic O response O . O CONCLUSIONS O : O Two O of O 5 O children O with O severe O adenovirus B-Disease disease I-Disease treated O with O intravenous O ribavirin B-Chemical recovered O . O The O availability O of O newer O rapid O diagnostic O techniques O , O such O as O polymerase O chain O reaction O , O may O make O earlier O , O more O effective O treatment O of O adenovirus B-Disease infection I-Disease possible O . O Given O the O seriousness O and O increasing O prevalence O of O adenovirus B-Disease disease I-Disease in O certain O hosts O , O especially O children O , O a O large O , O multicenter O clinical O trial O of O potentially O useful O anti O - O adenoviral O therapies O , O such O as O intravenous O ribavirin B-Chemical , O is O clearly O required O to O demonstrate O the O most O effective O and O least O toxic O therapy O . O Delayed O asystolic B-Disease cardiac B-Disease arrest I-Disease after O diltiazem B-Chemical overdose B-Disease ; O resuscitation O with O high O dose O intravenous O calcium B-Chemical . O A O 51 O year O old O man O took O a O mixed O overdose B-Disease including O 1 O . O 8 O - O 3 O . O 6 O g O of O diltiazem B-Chemical , O paracetamol B-Chemical , O aspirin B-Chemical , O isosorbide B-Chemical nitrate B-Chemical , O and O alcohol B-Chemical . O He O initially O presented O to O hospital O after O six O hours O with O mild O hypotension B-Disease and O was O treated O with O activated O charcoal O and O intravenous O fluids O . O Eighteen O hours O after O the O overdose B-Disease he O had O two O generalised O tonic B-Disease - I-Disease clonic I-Disease seizures I-Disease . O The O patient O remained O unresponsive O with O junctional O bradycardia B-Disease , O unrecordable O blood O pressure O , O and O then O became O asystolic B-Disease . O He O was O resuscitated O with O high O dose O ( O 13 O . O 5 O g O ) O intravenous O calcium B-Chemical and O adrenaline B-Chemical ( O epinephrine B-Chemical ) O . O He O required O inotropic O support O and O temporary O pacing O over O the O next O 48 O hours O . O This O case O suggests O there O is O a O role O for O aggressive O high O dose O intravenous O calcium B-Chemical therapy O in O severe O diltiazem B-Chemical overdose B-Disease , O particularly O with O the O onset O of O asystole B-Disease . O It O should O be O considered O early O in O cases O of O cardiac B-Disease arrest I-Disease after O diltiazem B-Chemical overdose B-Disease . O The O case O also O highlights O the O problems O with O delayed O toxicity B-Disease when O whole O bowel O irrigation O is O not O administered O . O Low B-Chemical - I-Chemical molecular I-Chemical - I-Chemical weight I-Chemical heparin I-Chemical for O the O treatment O of O patients O with O mechanical O heart O valves O . O BACKGROUND O : O The O interruption O of O oral O anticoagulant O ( O OAC O ) O administration O is O sometimes O indicated O in O patients O with O mechanical O heart O valves O , O mainly O before O noncardiac O surgery O , O non O - O surgical O interventions O , O and O pregnancy O . O Unfractionated B-Chemical heparin I-Chemical ( O UH B-Chemical ) O is O currently O the O substitute O for O selected O patients O . O Low B-Chemical - I-Chemical molecular I-Chemical - I-Chemical weight I-Chemical heparin I-Chemical ( O LMWH B-Chemical ) O offers O theoretical O advantages O over O UH B-Chemical , O but O is O not O currently O considered O in O clinical O guidelines O as O an O alternative O to O UH B-Chemical in O patients O with O prosthetic O valves O . O HYPOTHESIS O : O The O aim O of O the O present O study O was O to O review O the O data O accumulated O so O far O on O the O use O of O LMWH B-Chemical in O this O patient O population O and O to O discuss O its O applicability O in O common O practice O . O METHODS O : O For O this O paper O , O the O current O medical O literature O on O LMWH B-Chemical in O patients O with O mechanical O heart O valves O was O extensively O reviewed O . O RESULTS O : O There O were O eight O series O and O six O case O reports O . O None O of O the O studies O was O randomized O , O and O only O one O was O prospective O . O Data O to O establish O the O thromboembolic B-Disease risk O were O incomplete O . O After O excluding O case O reports O , O the O following O groups O were O constructed O : O ( O a O ) O short O - O term O administration O , O after O valve O insertion O ( O n O = O 212 O ) O ; O ( O b O ) O short O - O term O , O perioperative O ( O noncardiac O ) O / O periprocedural O ( O n O = O 114 O ) O ; O ( O c O ) O long O - O term O , O due O to O intolerance O to O OAC O ( O n O = O 16 O ) O ; O ( O d O ) O long O - O term O , O in O pregnancy O ( O n O = O 10 O ) O . O The O incidence O rate O of O thromboembolism B-Disease was O 0 O . O 9 O % O for O all O the O studies O and O 0 O . O 5 O , O 0 O , O 20 O , O and O 0 O % O in O groups O a O , O b O , O c O , O and O d O , O respectively O ; O for O hemorrhage B-Disease , O the O overall O rate O was O 3 O . O 4 O % O ( O 3 O . O 8 O , O 2 O . O 6 O , O 10 O , O and O 0 O % O for O the O respective O groups O ) O . O CONCLUSIONS O : O In O patients O with O mechanical O heart O valves O , O short O - O term O LMWH B-Chemical therapy O compares O favorably O with O UH B-Chemical . O Data O on O mid O - O and O long O - O term O LMWH B-Chemical administration O in O these O patients O are O sparse O . O Further O randomized O studies O are O needed O to O confirm O the O safety O and O precise O indications O for O the O use O of O LMWH B-Chemical in O patients O with O mechanical O heart O valves O . O Cardiac B-Disease arrest I-Disease after O intravenous O metoclopramide B-Chemical - O a O case O of O five O repeated O injections O of O metoclopramide B-Chemical causing O five O episodes O of O cardiac B-Disease arrest I-Disease . O We O describe O a O patient O where O intravenous O injection O of O metoclopramide B-Chemical was O immediately O followed O by O asystole B-Disease repeatedly O . O The O patient O received O metoclopramide B-Chemical 10 O mg O i O . O v O . O five O times O during O 48 O h O . O After O interviewing O the O attending O nurses O and O reviewing O the O written O documentation O , O it O is O clear O that O every O administration O of O metoclopramide B-Chemical was O immediately O ( O within O s O ) O followed O by O asystole B-Disease . O The O asystole B-Disease lasted O 15 O - O 30 O s O on O four O occasions O , O on O one O occasion O it O lasted O 2 O min O . O The O patient O received O atropine B-Chemical 0 O . O 5 O - O 1 O mg O and O chest O compressions O , O before O sinus O rhythm O again O took O over O . O We O interpret O this O as O episodes O of O cardiac B-Disease arrest I-Disease caused O by O metoclopramide B-Chemical . O The O rapid O injection O via O the O central O venous O route O and O the O concomitant O tapering O of O dopamine B-Chemical infusion O might O have O contributed O in O precipitating O the O adverse O drug O reaction O . O Immunohistochemical O study O on O inducible O type O of O nitric B-Chemical oxide I-Chemical ( O iNOS O ) O , O basic O fibroblast O growth O factor O ( O bFGF O ) O and O tumor B-Disease growth O factor O - O beta1 O ( O TGF O - O beta1 O ) O in O arteritis B-Disease induced O in O rats O by O fenoldopam B-Chemical and O theophylline B-Chemical , O vasodilators O . O Arteritis B-Disease induced O in O rats O by O vasodilators O , O fenoldopam B-Chemical and O theophylline B-Chemical , O was O examined O immunohistochemically O for O expressions O of O inducible O type O of O nitric B-Chemical oxide I-Chemical synthase O ( O iNOS O ) O , O basic O fibroblast O growth O factor O ( O bFGF O ) O and O tumor B-Disease growth O factor O - O beta1 O ( O TGF O - O beta1 O ) O . O Rats O were O administered O fenoldopam B-Chemical for O 24 O hours O by O intravenous O infusion O with O or O without O following O repeated O daily O oral O administrations O of O theophylline B-Chemical . O Irrespective O of O theophylline B-Chemical administration O , O iNOS O antigens O were O remarkably O abundant O in O ED O - O 1 O - O positive O cells O on O day O 5 O and O 8 O post O - O fenoldopam B-Chemical - O infusion O ( O DPI O ) O ; O bFGF O antigens O were O remarkably O abundant O in O ED O - O 1 O - O positive O cells O on O 1 O and O 3 O DPI O ; O TGF O - O beta1 O antigens O were O observed O in O ED O - O 1 O - O positive O cells O on O and O after O 5 O DPI O . O These O results O suggest O that O the O peak O expression O of O iNOS O antigen O was O followed O by O that O of O bFGF O antigen O , O and O bFGF O may O have O a O suppressive O effect O on O iNOS O expression O in O these O rat O arteritis B-Disease models O . O On O the O other O hand O , O TGF O - O beta1 O was O not O considered O to O have O a O suppressive O effect O on O iNOS O expression O in O these O models O . O The O striatum O as O a O target O for O anti O - O rigor O effects O of O an O antagonist O of O mGluR1 O , O but O not O an O agonist O of O group O II O metabotropic O glutamate B-Chemical receptors O . O The O aim O of O the O present O study O was O to O find O out O whether O the O metabotropic O receptor O 1 O ( O mGluR1 O ) O and O group O II O mGluRs O , O localized O in O the O striatum O , O are O involved O in O antiparkinsonian O - O like O effects O in O rats O .

O A O phase O II O study O of O thalidomide B-Chemical in O advanced O metastatic O renal B-Disease cell I-Disease carcinoma I-Disease . O OBJECTIVES O : O To O evaluate O the O toxicity B-Disease and O activity O of O thalidomide B-Chemical in O patients O with O advanced O metastatic O renal B-Disease cell I-Disease cancer I-Disease and O to O measure O changes O of O one O angiogenic O factor O , O vascular O endothelial O growth O factor O ( O VEGF O ) O 165 O , O with O therapy O . O PATIENTS O AND O METHODS O : O 29 O patients O were O enrolled O on O a O study O of O thalidomide B-Chemical using O an O intra O - O patient O dose O escalation O schedule O . O Patients O began O thalidomide B-Chemical at O 400 O mg O / O d O and O escalated O as O tolerated O to O 1200 O mg O / O d O by O day O 54 O . O Fifty O - O nine O per O cent O of O patients O had O had O previous O therapy O with O IL O - O 2 O and O 52 O % O were O performance O status O 2 O or O 3 O . O Systemic O plasma O VEGF165 O levels O were O measured O by O dual O monoclonal O ELISA O in O 8 O patients O . O RESULTS O : O 24 O patients O were O evaluable O for O response O with O one O partial O response O of O 11 O months O duration O of O a O patient O with O hepatic O and O pulmonary O metastases B-Disease ( O 4 O % O ) O , O one O minor O response O , O and O 2 O patients O stable O for O over O 6 O months O . O Somnolence B-Disease and O constipation B-Disease were O prominent O toxicities B-Disease and O most O patients O could O not O tolerate O the O 1200 O mg O / O day O dose O level O . O Systemic O plasma O VEGF165 O levels O did O not O change O with O therapy O . O CONCLUSION O : O These O results O are O consistent O with O a O low O level O of O activity O of O thalidomide B-Chemical in O renal B-Disease cell I-Disease carcinoma I-Disease . O Administration O of O doses O over O 800 O mg O / O day O was O difficult O to O achieve O in O this O patient O population O , O however O lower O doses O were O practical O . O The O dose O - O response O relationship O , O if O any O , O of O thalidomide B-Chemical for O renal B-Disease cell I-Disease carcinoma I-Disease is O unclear O . O Can O lidocaine B-Chemical reduce O succinylcholine B-Chemical induced O postoperative B-Disease myalgia I-Disease ? O This O study O was O undertaken O to O determine O the O effect O of O lidocaine B-Chemical pretreatment O on O reduction O of O succinylcholine B-Chemical - O induced O myalgia B-Disease in O patients O undergoing O general O anesthesia O for O gynecological O surgery O . O One O hundred O and O thirty O - O five O patients O were O assigned O to O one O of O three O groups O in O a O prospective O , O double O blind O , O randomized O manner O .

O 1 O mg O x O kg O ( O - O 1 O ) O iv O was O given O for O premedication O and O all O patients O were O monitored O with O a O noninvasive O blood O pressure O monitor O , O ECG O and O pulse O oximetry O . O Anesthesia O was O induced O with O 5 O mg O . O kg O ( O - O 1 O ) O thiopental B-Chemical iv O . O followed O by O succinylcholine B-Chemical ( O Group O PS O , O LS O ) O or O rocuronium B-Chemical ( O Group O PR O ) O for O tracheal O intubation O . O Following O administration O of O these O agents O , O the O presence O , O and O degree O of O fasciculation B-Disease were O assessed O visually O on O a O four O point O scale O by O one O investigator O who O was O blinded O to O the O drug O administered O . O The O blood O pressure O and O heart O rate O of O each O patient O were O monitored O on O nine O occasions O . O Twenty O - O four O hours O later O , O any O myalgia B-Disease experienced O was O assessed O according O to O a O structured O questionaire O and O graded O by O a O four O point O scale O by O one O investigator O blinded O to O the O intraoperative O management O . O The O results O indicate O that O muscle B-Disease fasciculation I-Disease was O not O found O in O Group O PR O while O the O patients O in O Group O LS O had O a O lower O incidence O of O muscle B-Disease fasciculation I-Disease than O those O in O Group O PS O ( O p O < O 0 O . O 001 O ) O . O At O 24 O h O , O the O incidence O of O myalgia B-Disease was O higher O in O Group O PS O than O in O Group O LS O and O PR O ( O p O < O 0 O . O 05 O ) O . O A O correlation O was O not O found O between O the O incidence O of O myalgia B-Disease and O the O occurrence O of O muscle B-Disease fasciculation I-Disease . O The O changes O in O systolic O and O diastolic O blood O pressure O and O heart O rate O were O not O significant O among O the O three O groups O . O In O conclusion O , O where O succinylcholine B-Chemical is O used O , O lidocaine B-Chemical is O proven O to O be O the O useful O pretreatment O agent O for O the O reduction O of O postoperative B-Disease myalgia I-Disease . O Reduced O sodium B-Chemical channel O density O , O altered O voltage O dependence O of O inactivation O , O and O increased O susceptibility O to O seizures B-Disease in O mice O lacking O sodium B-Chemical channel O beta O 2 O - O subunits O . O Sodium B-Chemical channel O beta O - O subunits O modulate O channel O gating O , O assembly O , O and O cell O surface O expression O in O heterologous O cell O systems O . O We O generated O beta2 O ( O - O / O - O ) O mice O to O investigate O the O role O of O beta2 O in O control O of O sodium B-Chemical channel O density O , O localization O , O and O function O in O neurons O in O vivo O . O Measurements O of O [ O ( O 3 O ) O H O ] O saxitoxin B-Chemical ( O STX B-Chemical ) O binding O showed O a O significant O reduction O in O the O level O of O plasma O membrane O sodium B-Chemical channels O in O beta2 O ( O - O / O - O ) O neurons O . O The O loss O of O beta2 O resulted O in O negative O shifts O in O the O voltage O dependence O of O inactivation O as O well O as O significant O decreases O in O sodium B-Chemical current O density O in O acutely O dissociated O hippocampal O neurons O . O The O integral O of O the O compound O action O potential O in O optic O nerve O was O significantly O reduced O , O and O the O threshold O for O action O potential O generation O was O increased O , O indicating O a O reduction O in O the O level O of O functional O plasma O membrane O sodium B-Chemical channels O . O In O contrast O , O the O conduction O velocity O , O the O number O and O size O of O axons O in O the O optic O nerve O , O and O the O specific O localization O of O Na B-Chemical ( O v O ) O 1 O . O 6 O channels O in O the O nodes O of O Ranvier O were O unchanged O . O beta2 O ( O - O / O - O ) O mice O displayed O increased O susceptibility O to O seizures B-Disease , O as O indicated O by O reduced O latency O and O threshold O for O pilocarpine B-Chemical - O induced O seizures B-Disease , O but O seemed O normal O in O other O neurological O tests O . O Our O observations O show O that O beta2 O - O subunits O play O an O important O role O in O the O regulation O of O sodium B-Chemical channel O density O and O function O in O neurons O in O vivo O and O are O required O for O normal O action O potential O generation O and O control O of O excitability O . O Acute B-Disease liver I-Disease failure I-Disease with O concurrent O bupropion B-Chemical and O carbimazole B-Chemical therapy O . O OBJECTIVE O : O To O report O a O case O of O fatal O liver B-Disease failure I-Disease possibly O associated O with O concurrent O use O of O bupropion B-Chemical and O carbimazole B-Chemical . O CASE O SUMMARY O : O A O 41 O - O year O - O old O Chinese O man O with O a O history O of O hyperthyroidism B-Disease had O been O treated O with O carbimazole B-Chemical and O propranolol B-Chemical for O the O past O 5 O years O . O He O received O a O 10 O - O day O course O of O bupropion B-Chemical as O an O aid O for O smoking O cessation O 10 O weeks O prior O to O presentation O . O He O developed O acute B-Disease liver I-Disease failure I-Disease with O rapid O deterioration O of O renal O function O . O Liver O biopsy O showed O evidence O of O nonspecific O drug B-Disease - I-Disease induced I-Disease acute I-Disease liver I-Disease injury I-Disease . O His O condition O was O further O complicated O by O sepsis B-Disease and O coagulopathy B-Disease . O Death O resulted O 19 O days O after O the O onset O of O symptoms O . O The O likelihood O that O bupropion B-Chemical induced O hepatotoxicity B-Disease in O our O patient O was O possible O , O based O on O the O Naranjo O probability O scale O . O DISCUSSION O : O Although O there O is O increasing O evidence O of O hepatotoxicity B-Disease induced O by O bupropion B-Chemical , O this O is O the O first O case O of O fatality O that O could O have O resulted O from O acute B-Disease liver I-Disease failure I-Disease in O a O patient O receiving O bupropion B-Chemical while O on O concomitant O treatment O with O carbimazole B-Chemical . O CONCLUSIONS O : O Clinicians O should O be O aware O of O the O possibility O of O acute B-Disease liver I-Disease insult I-Disease induced O by O bupropion B-Chemical given O concurrently O with O other O hepatotoxic B-Disease drugs O . O Pyeloureteral O filling O defects O associated O with O systemic O anticoagulation O : O a O case O report O . O The O etiology O of O pyeloureteritis B-Disease cystica I-Disease has O long O been O attributed O to O chronic O infection B-Disease and O inflammation B-Disease . O A O case O is O presented O that O is O unique O in O that O the O acute O onset O and O the O rapid O resolution O of O pyeloureteral O filling O defects O in O this O patient O were O documented O by O radiography O . O There O is O no O evidence O of O antecedent O or O concurrent O infection B-Disease in O this O patient O . O The O disease O occurred O subsequent O to O the O initiation O of O heparin B-Chemical therapy O for O suspected O pelvic O thrombophlebitis B-Disease and O cleared O rapidly O subsequent O to O its O discontinuation O . O The O rate O of O resolution O of O the O radiographic O findings O may O be O helpful O in O distinguishing O between O true O pyeloureteritis B-Disease cystica I-Disease and O submucosal B-Disease hemorrhage I-Disease . O Nephrotoxic B-Disease effects O in O high O - O risk O patients O undergoing O angiography O . O BACKGROUND O : O The O use O of O iodinated O contrast O medium O can O result O in O nephropathy B-Disease . O Whether O iso O - O osmolar O contrast O medium O is O less O nephrotoxic B-Disease than O low O - O osmolar O contrast O medium O in O high O - O risk O patients O is O uncertain O . O METHODS O : O We O conducted O a O randomized O , O double O - O blind O , O prospective O , O multicenter O study O comparing O the O nephrotoxic B-Disease effects O of O an O iso O - O osmolar O , O dimeric O , O nonionic O contrast O medium O , O iodixanol B-Chemical , O with O those O of O a O low O - O osmolar O , O nonionic O , O monomeric O contrast O medium O , O iohexol B-Chemical . O The O study O involved O 129 O patients O with O diabetes B-Disease with O serum O creatinine B-Chemical concentrations O of O 1 O . O 5 O to O 3 O . O 5 O mg O per O deciliter O who O underwent O coronary O or O aortofemoral O angiography O . O The O primary O end O point O was O the O peak O increase O from O base O line O in O the O creatinine B-Chemical concentration O during O the O three O days O after O angiography O . O Other O end O points O were O an O increase O in O the O creatinine B-Chemical concentration O of O 0 O . O 5 O mg O per O deciliter O or O more O , O an O increase O of O 1 O .

O RESULTS O : O The O creatinine B-Chemical concentration O increased O significantly O less O in O patients O who O received O iodixanol B-Chemical . O From O day O 0 O to O day O 3 O , O the O mean O peak O increase O in O creatinine B-Chemical was O 0 O . O 13 O mg O per O deciliter O in O the O iodixanol B-Chemical group O and O 0 O .

O CONCLUSIONS O : O Nephropathy B-Disease induced O by O contrast O medium O may O be O less O likely O to O develop O in O high O - O risk O patients O when O iodixanol B-Chemical is O used O rather O than O a O low O - O osmolar O , O nonionic O contrast O medium O . O Protective O effect O of O edaravone B-Chemical against O streptomycin B-Chemical - O induced O vestibulotoxicity B-Disease in O the O guinea O pig O . O This O study O investigated O alleviation O of O streptomycin B-Chemical - O induced O vestibulotoxicity B-Disease by O edaravone B-Chemical in O guinea O pigs O . O Edaravone B-Chemical , O a O free O radical O scavenger O , O has O potent O free O radical O quenching O action O and O is O used O in O clinical O practice O to O treat O cerebral B-Disease infarction I-Disease . O Streptomycin B-Chemical was O administered O to O the O inner O ear O by O osmotic O pump O for O 24 O h O , O and O edaravone B-Chemical ( O n O = O 8 O ) O or O saline O ( O n O = O 6 O ) O was O intraperitoneally O injected O once O a O day O for O 7 O days O . O We O observed O horizontal O vestibulo O - O ocular O reflex O as O a O marker O of O postoperative O vestibular O function O . O Animals O injected O with O saline O showed O statistically O smaller O gains O than O those O injected O with O edaravone B-Chemical . O These O results O suggest O that O edaravone B-Chemical suppresses O streptomycin B-Chemical - O induced O vestibulotoxicity B-Disease . O Levodopa B-Chemical - O induced O oromandibular O dystonia B-Disease in O progressive B-Disease supranuclear I-Disease palsy I-Disease . O Levodopa B-Chemical - O induced O dyskinesias B-Disease have O been O reported O in O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease and O multiple B-Disease system I-Disease atrophy I-Disease . O Cranial O dystonias B-Disease are O rare O in O patients O with O progressive B-Disease supranuclear I-Disease palsy I-Disease ( O PSP B-Disease ) O . O In O this O report O we O describe O an O unusual O case O of O reversible O levodopa B-Chemical - O induced O Oromandibular B-Disease dystonia I-Disease ( O OMD B-Disease ) O in O a O PSP B-Disease patient O to O highlight O the O importance O of O recognizing O this O drug O related O complication O in O the O management O of O PSP B-Disease , O and O discuss O the O possible O underlying O pathophysiology O . O Case O report O : O Dexatrim B-Chemical ( O Phenylpropanolamine B-Chemical ) O as O a O cause O of O myocardial B-Disease infarction I-Disease . O Phenylpropanolamine B-Chemical ( O PPA B-Chemical ) O is O a O sympathetic O amine B-Chemical used O in O over O - O the O - O counter O cold O remedies O and O weight O - O control O preparations O worldwide O . O Its O use O has O been O associated O with O hypertensive B-Disease episodes O and O hemorrhagic B-Disease strokes I-Disease in O younger O women O . O Several O reports O have O linked O the O abuse O of O PPA B-Chemical with O myocardial B-Disease injury I-Disease , O especially O when O overdose B-Disease is O involved O . O We O report O here O the O first O case O of O Dexatrim B-Chemical ( O PPA B-Chemical ) O - O induced O myocardial B-Disease injury I-Disease in O a O young O woman O who O was O using O it O at O recommended O doses O for O weight O control O . O In O addition O , O we O review O the O 7 O other O cases O of O PPA B-Chemical related O myocardial B-Disease injury I-Disease that O have O been O reported O so O far O . O Physicians O and O patients O should O be O alert O to O the O potential O cardiac O risk O associated O with O the O use O of O PPA B-Chemical , O even O at O doses O generally O considered O to O be O safe O . O Differential O diagnosis O of O high O serum O creatine B-Chemical kinase O levels O in O systemic B-Disease lupus I-Disease erythematosus I-Disease . O We O report O the O clinical O and O bioptic O findings O for O a O 57 O - O year O - O old O woman O with O severe O chloroquine B-Chemical - O induced O myopathy B-Disease . O Since O 1989 O , O she O had O been O suffering O from O systemic B-Disease lupus I-Disease erythematosus I-Disease ( O SLE B-Disease ) O with O renal B-Disease involvement I-Disease and O undergone O periods O of O treatment O with O azathioprine B-Chemical and O cyclophosphamide B-Chemical . O Additional O therapy O with O chloroquine B-Chemical ( O CQ B-Chemical ) O was O started O because O of O arthralgia B-Disease . O At O the O same O time O , O slightly O increased O creatine B-Chemical kinase O ( O CK O ) O levels O were O noted O . O Myositis B-Disease was O suspected O , O and O the O patient O was O treated O with O steroids B-Chemical . O The O CK O increase O persisted O , O however O , O and O she O developed O progressive O muscular B-Disease weakness I-Disease and O muscular B-Disease atrophy I-Disease . O Routine O controls O revealed O markedly O elevated O CK O levels O of O 1 O , O 700 O U O / O l O . O The O neurological O and O electrophysiological O findings O were O not O typical O of O myositis B-Disease . O Thus O , O muscle O biopsy O of O the O deltoid O muscle O was O performed O in O order O to O exclude O polymyositis B-Disease or O toxic O myopathy B-Disease . O As O it O revealed O chloroquine B-Chemical - O induced O myopathy B-Disease , O medication O was O stopped O . O Discriminating O between O primary O SLE B-Disease - O induced O affection B-Disease of I-Disease the I-Disease musculoskeletal I-Disease system I-Disease and O drug O - O induced O side O effects O is O important O for O appropriate O treatment O of O SLE B-Disease patients O . O Seizure B-Disease associated O with O sleep B-Disease deprivation I-Disease and O sustained O - O release O bupropion B-Chemical . O This O case O report O describes O a O generalized O seizure B-Disease associated O with O sustained O - O release O bupropion B-Chemical use O and O sleep B-Disease deprivation I-Disease . O The O subject O , O a O 31 O - O year O - O old O female O smoker O , O was O participating O in O a O clinical O trial O evaluating O an O investigational O medication O for O smoking O cessation O that O used O sustained O - O release O bupropion B-Chemical as O an O active O control O . O After O 5 O weeks O of O bupropion B-Chemical use O , O the O subject O experienced O a O generalized O tonic O clonic O seizure B-Disease after O staying O up O nearly O all O night O packing O and O moving O to O a O new O residence O . O The O patient O had O no O other O risk O factors O for O seizures B-Disease . O We O suggest O that O sleep B-Disease deprivation I-Disease may O add O to O the O risk O of O bupropion B-Chemical - O associated O seizures B-Disease . O Postoperative B-Disease myalgia I-Disease after O succinylcholine B-Chemical : O no O evidence O for O an O inflammatory O origin O . O A O common O side O effect O associated O with O succinylcholine B-Chemical is O postoperative B-Disease myalgia I-Disease . O The O pathogenesis O of O this O myalgia B-Disease is O still O unclear O ; O inflammation B-Disease has O been O suggested O but O without O convincing O evidence O . O We O designed O the O present O study O to O investigate O whether O an O inflammatory O reaction O contributes O to O this O myalgia B-Disease . O The O incidence O and O severity O of O succinylcholine B-Chemical - O associated O myalgia B-Disease was O determined O in O 64 O patients O pretreated O with O saline O or O dexamethasone B-Chemical before O succinylcholine B-Chemical ( O n O = O 32 O for O each O ) O . O Incidence O and O severity O of O myalgia B-Disease did O not O differ O significantly O between O the O two O groups O : O 15 O patients O in O the O dexamethasone B-Chemical group O complained O of O myalgia B-Disease compared O with O 18 O patients O in O the O saline O group O , O and O severe O myalgia B-Disease was O reported O by O five O patients O and O three O patients O , O respectively O ( O not O significant O ) O . O At O 48 O h O after O surgery O , O 12 O patients O in O both O groups O still O suffered O from O myalgia B-Disease ( O not O significant O ) O . O In O addition O , O interleukin O - O 6 O ( O IL O - O 6 O ) O as O an O early O marker O of O inflammation B-Disease was O assessed O in O a O subgroup O of O 10 O patients O pretreated O with O saline O . O We O found O an O increase O of O IL O - O 6 O for O only O three O patients O , O but O only O one O patient O reported O myalgia B-Disease ; O no O relationship O between O myalgia B-Disease and O the O increase O of O IL O - O 6 O was O found O . O In O conclusion O , O there O is O no O evidence O for O an O inflammatory O origin O of O succinylcholine B-Chemical - O associated O myalgia B-Disease . O IMPLICATIONS O : O Administration O of O dexamethasone B-Chemical before O succinylcholine B-Chemical was O not O effective O in O decreasing O the O incidence O or O the O severity O of O succinylcholine B-Chemical - O induced O postoperative B-Disease myalgia I-Disease . O Furthermore O , O there O was O no O significant O relationship O between O postoperative B-Disease myalgia I-Disease and O time O course O of O interleukin O - O 6 O concentrations O , O a O marker O of O inflammation B-Disease . O Pretreatment O with O dexamethasone B-Chemical is O not O justified O to O prevent O postoperative B-Disease myalgia I-Disease after O succinylcholine B-Chemical . O Effect O of O lindane B-Chemical on O hepatic O and O brain O cytochrome O P450s O and O influence O of O P450 O modulation O in O lindane B-Chemical induced O neurotoxicity B-Disease . O Oral O administration O of O lindane B-Chemical ( O 2 O . O 5 O , O 5 O , O 10 O and O 15 O mg O / O kg O , O body O weight O ) O for O 5 O days O was O found O to O produce O a O dose O - O dependent O increase O in O the O activity O of O P450 O dependent O 7 O - O ethoxyresorufin O - O O O - O deethylase O ( O EROD O ) O , O 7 O - O pentoxyresorufin O - O O O - O dealkylase O ( O PROD O ) O and O N B-Chemical - I-Chemical nitrosodimethylamine I-Chemical demethylase O ( O NDMA B-Chemical - O d O ) O in O rat O brain O and O liver O . O A O significant O increase O in O the O hepatic O and O brain O P450 O monooxygenases O was O also O observed O when O the O duration O of O exposure O of O low O dose O ( O 2 O . O 5 O mg O / O kg O ) O of O lindane B-Chemical was O increased O from O 5 O days O to O 15 O or O 21 O days O . O As O observed O with O different O doses O , O the O magnitude O of O induction O in O the O activity O of O P450 O monooxygenases O was O several O fold O higher O in O liver O microsomes O when O compared O with O the O brain O . O Western O blotting O studies O have O indicated O that O the O increase O in O the O P450 O enzymes O could O be O due O to O the O increase O in O the O expression O of O P450 O 1A1 O / O 1A2 O , O 2B1 O / O 2B2 O and O 2E1 O isoenzymes O .

O METHODS O : O ASA B-Chemical was O administered O as O a O single O dose O on O GD O 9 O ( O 0 O , O 250 O , O 500 O , O or O 625 O mg O / O kg O ) O , O 10 O ( O 0 O , O 500 O , O 625 O , O or O 750 O mg O / O kg O ) O , O or O 11 O ( O 0 O , O 500 O , O 750 O , O or O 1000 O mg O / O kg O ) O and O from O GD O 6 O to O GD O 17 O ( O 0 O , O 50 O , O 125 O , O or O 250 O mg O / O kg O a O day O ) O in O the O multiple O dose O study O to O SD O rats O . O Animals O were O killed O on O GD O 21 O , O and O fetuses O were O examined O viscerally O . O RESULTS O : O The O literature O evaluation O suggested O that O NSAIDs O induce O ventricular B-Disease septal I-Disease defects I-Disease ( O VSDs B-Disease ) O and O midline B-Disease defects I-Disease ( O MDs B-Disease ) O in O rats O and O diaphragmatic B-Disease hernia I-Disease ( O DH B-Disease ) O , O MDs B-Disease , O and O VSDs B-Disease in O rabbits O ( O Cook O JC O et O al O . O , O 2003 O ) O ; O hence O , O the O present O study O focused O on O these O malformations B-Disease , O even O though O ASA B-Chemical induces O several O other O low O - O incidence O malformations B-Disease . O In O single O dose O studies O , O DH B-Disease , O MD B-Disease , O and O VSD B-Disease were O induced O on O GDs O 9 O and O 10 O .

O ( O ABSTRACT O TRUNCATED O AT O 400 O WORDS O ) O Hemolytic B-Disease - I-Disease uremic I-Disease syndrome I-Disease associated O with O ingestion O of O quinine B-Chemical . O Hemolytic B-Disease - I-Disease uremic I-Disease syndrome I-Disease following O quinine B-Chemical ingestion O is O a O newly O described O phenomenon O , O with O just O two O previous O descriptions O of O 4 O cases O in O the O literature O . O We O describe O a O 5th O case O . O The O reaction O may O be O mediated O by O the O presence O of O antibodies O reactive O against O platelets O in O the O presence O of O quinine B-Chemical . O Treatment O has O included O use O of O plasma O exchange O , O prednisone B-Chemical , O aspirin B-Chemical , O and O dipyridamole B-Chemical . O The O patients O have O all O regained O some O degree O of O renal O function O . O However O , O it O is O unclear O whether O pharmacological O treatment O or O spontaneous O resolution O is O responsible O for O the O improvement O . O Quinine B-Chemical - O associated O hemolytic B-Disease - I-Disease uremic I-Disease syndrome I-Disease probably O occurs O more O often O than O is O recognized O . O It O is O important O to O recognize O this O reaction O when O it O occurs O and O to O avoid O further O quinine B-Chemical exposure O , O since O the O reaction O seems O to O be O recurrent O . O Amnestic B-Disease syndrome I-Disease associated O with O propranolol B-Chemical toxicity B-Disease : O a O case O report O . O An O elderly O woman O developed O an O Alzheimer B-Disease - O like O subacute O dementia B-Disease as O a O result O of O propranolol B-Chemical toxicity B-Disease . O Analysis O of O the O manifestations O showed O that O severe O impairment O of O memory O accounted O for O virtually O all O of O the O abnormalities O . O There O is O evidence O that O cerebral O reactions O to O drug O toxicity B-Disease can O exhibit O patterns O that O suggest O highly O selective O involvement O of O functional O subdivisions O of O the O brain O . O Cefotetan B-Chemical - O induced O immune O hemolytic B-Disease anemia I-Disease . O Immune O hemolytic B-Disease anemia I-Disease due O to O a O drug O - O adsorption O mechanism O has O been O described O primarily O in O patients O receiving O penicillins B-Chemical and O first O - O generation O cephalosporins B-Chemical . O We O describe O a O patient O who O developed O anemia B-Disease while O receiving O intravenous O cefotetan B-Chemical . O Cefotetan B-Chemical - O dependent O antibodies O were O detected O in O the O patient O ' O s O serum O and O in O an O eluate O prepared O from O his O red O blood O cells O . O The O eluate O also O reacted O weakly O with O red O blood O cells O in O the O absence O of O cefotetan B-Chemical , O suggesting O the O concomitant O formation O of O warm O - O reactive O autoantibodies O . O These O observations O , O in O conjunction O with O clinical O and O laboratory O evidence O of O extravascular O hemolysis B-Disease , O are O consistent O with O drug O - O induced O hemolytic B-Disease anemia I-Disease , O possibly O involving O both O drug O - O adsorption O and O autoantibody O formation O mechanisms O . O This O case O emphasizes O the O need O for O increased O awareness O of O hemolytic O reactions O to O all O cephalosporins B-Chemical . O Use O of O dexamethasone B-Chemical with O mesna B-Chemical for O the O prevention O of O ifosfamide B-Chemical - O induced O hemorrhagic B-Disease cystitis I-Disease . O AIM O : O Hemorrhagic B-Disease cystitis I-Disease ( O HC B-Disease ) O is O a O limiting O side O - O effect O of O chemotherapy O with O ifosfamide B-Chemical ( O IFS B-Chemical ) O . O In O the O study O presented O here O , O we O investigated O the O use O of O dexamethasone B-Chemical in O combination O with O mesna B-Chemical for O the O prevention O of O IFS B-Chemical - O induced O HC B-Disease . O METHODS O : O Male O Wistar O rats O ( O 150 O - O 200 O g O ; O 6 O rats O per O group O ) O were O treated O with O saline O or O mesna B-Chemical 5 O min O ( O i O . O p O . O ) O before O and O 2 O and O 6 O h O after O ( O v O . O o O . O ) O administration O of O IFS B-Chemical . O One O , O two O or O three O doses O of O mesna B-Chemical were O replaced O with O dexamethasone B-Chemical alone O or O with O dexamethasone B-Chemical plus O mesna B-Chemical . O Cystitis B-Disease was O evaluated O 24 O h O after O its O induction O by O the O changes O in O bladder O wet O weight O and O by O macroscopic O and O microscopic O analysis O . O RESULTS O : O The O replacement O of O the O last O dose O or O the O last O two O doses O of O mesna B-Chemical with O dexamethasone B-Chemical reduced O the O increase O in O bladder O wet O weight O induced O by O IFS B-Chemical by O 84 O . O 79 O % O and O 89 O . O 13 O % O , O respectively O . O In O addition O , O it O almost O abolished O the O macroscopic O and O microscopic O alterations O induced O by O IFS B-Chemical . O Moreover O , O the O addition O of O dexamethasone B-Chemical to O the O last O two O doses O of O mesna B-Chemical was O more O efficient O than O three O doses O of O mesna B-Chemical alone O when O evaluated O microscopically O . O CONCLUSION O : O Dexamethasone B-Chemical in O combination O with O mesna B-Chemical was O efficient O in O blocking O IFS B-Chemical - O induced O HC B-Disease . O However O , O the O replacement O of O last O two O doses O of O mesna B-Chemical with O saline O or O all O of O the O mesna B-Chemical doses O with O dexamethasone B-Chemical did O not O prevent O HC B-Disease . O All B-Chemical - I-Chemical trans I-Chemical - I-Chemical retinoic I-Chemical acid I-Chemical - O induced O erythema B-Disease nodosum I-Disease in O patients O with O acute B-Disease promyelocytic I-Disease leukemia I-Disease . O Erythema B-Disease nodosum I-Disease associated O with O all B-Chemical - I-Chemical trans I-Chemical - I-Chemical retinoic I-Chemical acid I-Chemical ( O ATRA B-Chemical ) O for O acute B-Disease promyelocytic I-Disease leukemia I-Disease ( O APL B-Disease ) O is O very O rare O . O We O describe O four O patients O with O classic O APL B-Disease who O developed O erythema B-Disease nodosum I-Disease during O ATRA B-Chemical therapy O . O Fever B-Disease and O subsequent O multiple O painful B-Disease erythematous B-Disease nodules I-Disease over O extremities O developed O on O D11 O , O D16 O , O D17 O , O and O D19 O , O respectively O , O after O ATRA B-Chemical therapy O . O The O skin O biopsy O taken O from O each O patient O was O consistent O with O erythema B-Disease nodosum I-Disease . O All O patients O received O short O course O of O steroids B-Chemical . O Fever B-Disease subsided O rapidly O and O the O skin O lesions O regressed O completely O . O All O patients O achieved O complete O remission O without O withdrawal O of O ATRA B-Chemical . O ATRA B-Chemical seemed O to O be O the O most O possible O etiology O of O erythema B-Disease nodosum I-Disease in O our O patients O . O Short O - O term O use O of O steroid B-Chemical is O very O effective O in O ATRA B-Chemical - O induced O erythema B-Disease nodosum I-Disease . O Effect O of O some O convulsants O on O the O protective O activity O of O loreclezole B-Chemical and O its O combinations O with O valproate B-Chemical or O clonazepam B-Chemical in O amygdala O - O kindled O rats O . O Loreclezole B-Chemical ( O 5 O mg O / O kg O ) O exerted O a O significant O protective O action O in O amygdala O - O kindled O rats O , O reducing O both O seizure B-Disease and O afterdischarge O durations O . O The O combinations O of O loreclezole B-Chemical ( O 2 O . O 5 O mg O / O kg O ) O with O valproate B-Chemical , O clonazepam B-Chemical , O or O carbamazepine B-Chemical ( O applied O at O their O subprotective O doses O ) O also O exhibited O antiseizure O effect O in O this O test O . O However O , O only O two O first O combinations O occurred O to O be O of O pharmacodynamic O nature O . O Among O several O chemoconvulsants O , O bicuculline B-Chemical , O N B-Chemical - I-Chemical methyl I-Chemical - I-Chemical D I-Chemical - I-Chemical aspartic I-Chemical acid I-Chemical and O BAY B-Chemical k I-Chemical - I-Chemical 8644 I-Chemical ( O the O opener O of O L O - O type O calcium B-Chemical channels O ) O reversed O the O protective O activity O of O loreclezole B-Chemical alone O and O its O combination O with O valproate B-Chemical . O On O the O other O hand O , O bicuculline B-Chemical , O aminophylline B-Chemical and O BAY B-Chemical k I-Chemical - I-Chemical 8644 I-Chemical inhibited O the O anticonvulsive O action O of O loreclezole B-Chemical combined O with O clonazepam B-Chemical . O The O results O support O the O hypothesis O that O the O protective O activity O of O loreclezole B-Chemical and O its O combinations O with O other O antiepileptics O may O involve O potentiation O of O GABAergic O neurotransmission O and O blockade O of O L O - O type O of O calcium B-Chemical channels O . O Mitochondrial O DNA O and O its O respiratory O chain O products O are O defective O in O doxorubicin B-Chemical nephrosis B-Disease . O BACKGROUND O : O Doxorubicin B-Chemical induces O a O self O - O perpetuating O nephropathy B-Disease characterized O by O early O glomerular B-Disease and I-Disease late I-Disease - I-Disease onset I-Disease tubular I-Disease lesions I-Disease in O rats O . O We O investigated O the O potential O role O of O mitochondrial B-Disease injury I-Disease in O the O onset O of O these O lesions O . O METHODS O : O Rats O were O treated O with O intravenous O doxorubicin B-Chemical ( O 1 O mg O kg O ( O - O 1 O ) O week O ( O - O 1 O ) O ) O for O 7 O weeks O and O were O sacrificed O either O 1 O week O ( O ' O short O - O term O ' O ) O or O 30 O weeks O ( O ' O long O - O term O ' O ) O following O the O last O dose O . O Additional O rats O received O a O single O dose O either O 6 O days O or O 2 O h O prior O to O euthanasia O . O All O rats O were O killed O at O 48 O weeks O of O age O . O Glomerular B-Disease and I-Disease tubular I-Disease injury I-Disease was O monitored O and O correlated O to O the O activity O or O expression O of O respiratory O chain O components O . O Finally O , O we O quantified O both O nuclear O and O mitochondrial O DNA O ( O mtDNA O ) O as O well O as O superoxide B-Chemical production O and O the O 4834 O base O pair O ' O common O ' O mtDNA O deletion O . O RESULTS O : O The O ' O long O - O term O ' O group O had O significant O glomerular B-Disease and I-Disease tubular I-Disease lesions I-Disease , O depressed O activities O of O mtDNA O - O encoded O NADH O dehydrogenase O and O cytochrome O - O c O oxidase O ( O COX O ) O and O increased O citrate B-Chemical synthase O activity O . O In O addition O , O expression O of O the O mtDNA O - O encoded O COX O subunit O I O was O reduced O and O mtDNA O levels O were O decreased O . O In O ' O short O - O term O ' O rats O , O there O were O fewer O tubular B-Disease lesions I-Disease , O but O similar O numbers O of O glomerular B-Disease lesions I-Disease activity O . O Among O all O animals O , O glomerular B-Disease and I-Disease tubular I-Disease injury I-Disease were O inversely O correlated O with O mtDNA O levels O , O mtDNA O - O encoded O respiratory O chain O activities O and O with O the O expression O of O the O mtDNA O - O encoded O respiratory O chain O subunit O COX O - O I O . O Injury O was O positively O correlated O with O superoxide B-Chemical production O and O the O activities O of O nucleus O - O encoded O mitochondrial O or O cytoplasmic O enzymes O . O Kidneys O from O the O ' O long O - O term O ' O group O showed O more O mtDNA O deletions O than O in O ' O short O - O term O ' O animals O and O these O were O not O observed O in O the O other O groups O . O CONCLUSIONS O : O These O results O suggest O an O important O role O for O quantitative O and O qualitative O mtDNA O alterations O through O the O reduction O of O mtDNA O - O encoded O respiratory O chain O function O and O induction O of O superoxide B-Chemical in O doxorubicin B-Chemical - O induced O renal B-Disease lesions I-Disease . O A O randomized O , O placebo O - O controlled O , O crossover O study O of O ephedrine B-Chemical for O SSRI O - O induced O female O sexual B-Disease dysfunction I-Disease . O The O objective O of O this O study O was O to O determine O whether O ephedrine B-Chemical , O an O alpha O - O and O beta O - O adrenergic O agonist O previously O shown O to O enhance O genital O blood O flow O in O women O , O has O beneficial O effects O in O reversing O antidepressant O - O induced O sexual B-Disease dysfunction I-Disease . O Nineteen O sexually B-Disease dysfunctional I-Disease women O receiving O either O fluoxetine B-Chemical , O sertraline B-Chemical , O or O paroxetine B-Chemical participated O in O an O eight O - O week O , O double O - O blind O , O placebo O - O controlled O , O cross O - O over O study O of O the O effects O of O ephedrine B-Chemical ( O 50 O mg O ) O on O self O - O report O measures O of O sexual O desire O , O arousal O , O orgasm O , O and O sexual O satisfaction O . O Although O there O were O significant O improvements O relative O to O baseline O in O sexual O desire O and O orgasm O intensity O / O pleasure O on O 50 O mg O ephedrine B-Chemical 1 O - O hr O prior O to O sexual O activity O , O significant O improvements O in O these O measures O , O as O well O as O in O sexual O arousal O and O orgasmic O ability O also O were O noted O with O placebo O . O These O findings O highlight O the O importance O of O conducting O placebo O - O controlled O trials O for O this O condition O . O Does O hormone O therapy O for O the O treatment O of O breast B-Disease cancer I-Disease have O a O detrimental B-Disease effect I-Disease on I-Disease memory I-Disease and I-Disease cognition I-Disease ? O A O pilot O study O . O This O pilot O study O examines O whether O hormone O therapy O for O breast B-Disease cancer I-Disease affects O cognition O . O Patients O participating O in O a O randomised O trial O of O anastrozole B-Chemical , O tamoxifen B-Chemical alone O or O combined O ( O ATAC O ) O ( O n O = O 94 O ) O and O a O group O of O women O without O breast B-Disease cancer I-Disease ( O n O = O 35 O ) O completed O a O battery O of O neuropsychological O measures O . O Compared O with O the O control O group O , O the O patients O were O impaired O on O a O processing O speed O task O ( O p O = O 0 O . O 032 O ) O and O on O a O measure O of O immediate O verbal O memory O ( O p O = O 0 O . O 026 O ) O after O controlling O for O the O use O of O hormone O replacement O therapy O in O both O groups O . O Patient O group O performance O was O not O significantly O related O to O length O of O treatment O or O measures O of O psychological O morbidity O . O The O results O showed O specific O impairments O in O processing O speed O and O verbal O memory O in O women O receiving O hormonal O therapy O for O the O treatment O of O breast B-Disease cancer I-Disease . O Verbal O memory O may O be O especially O sensitive O to O changes O in O oestrogen B-Chemical levels O , O a O finding O commonly O reported O in O studies O of O hormone O replacement O therapy O in O healthy O women O . O In O view O of O the O increased O use O of O hormone O therapies O in O an O adjuvant O and O preventative O setting O their O impact O on O cognitive O functioning O should O be O investigated O more O thoroughly O . O Expression O of O p300 O protects O cardiac O myocytes O from O apoptosis O in O vivo O . O Doxorubicin B-Chemical is O an O anti O - O tumor B-Disease agent O that O represses O cardiac O - O specific O gene O expression O and O induces O myocardial O cell O apoptosis O . O Doxorubicin B-Chemical depletes O cardiac O p300 O , O a O transcriptional O coactivator O that O is O required O for O the O maintenance O of O the O differentiated O phenotype O of O cardiac O myocytes O . O However O , O the O role O of O p300 O in O protection O against O doxorubicin B-Chemical - O induced O apoptosis O is O unknown O . O Transgenic O mice O overexpressing O p300 O in O the O heart O and O wild O - O type O mice O were O subjected O to O doxorubicin B-Chemical treatment O . O Compared O with O wild O - O type O mice O , O transgenic O mice O exhibited O higher O survival O rate O as O well O as O more O preserved O left O ventricular O function O and O cardiac O expression O of O alpha O - O sarcomeric O actin O . O Doxorubicin B-Chemical induced O myocardial O cell O apoptosis O in O wild O - O type O mice O but O not O in O transgenic O mice O . O Expression O of O p300 O increased O the O cardiac O level O of O bcl O - O 2 O and O mdm O - O 2 O , O but O not O that O of O p53 O or O other O members O of O the O bcl O - O 2 O family O . O These O findings O demonstrate O that O overexpression O of O p300 O protects O cardiac O myocytes O from O doxorubicin B-Chemical - O induced O apoptosis O and O reduces O the O extent O of O acute O heart B-Disease failure I-Disease in O adult O mice O in O vivo O . O Methimazole B-Chemical - O induced O cholestatic B-Disease jaundice I-Disease . O Methimazole B-Chemical is O a O widely O used O and O generally O well O - O tolerated O antithyroid O agent O . O A O 43 O - O year O - O old O woman O had O severe O jaundice B-Disease and O itching B-Disease 1 O month O after O receiving O methimazole B-Chemical ( O 10 O mg O tid O ) O and O propranolol B-Chemical ( O 20 O mg O tid O ) O for O treatment O of O hyperthyroidism B-Disease . O The O patient O continued O treatment O for O another O 4 O days O after O the O appearance O of O jaundice B-Disease until O she O finished O both O medications O . O When O seen O at O the O emergency O department O 2 O weeks O later O , O she O still O had O severe O icterus B-Disease , O pruritus B-Disease , O and O hyperbilirubinemia B-Disease , O formed O mainly O of O the O conjugated O fraction O . O Methimazole B-Chemical - O induced O cholestasis B-Disease was O diagnosed O , O and O propranolol B-Chemical therapy O was O resumed O . O Over O the O following O 9 O days O , O the O symptoms O improved O and O plasma O bilirubin B-Chemical levels O were O normal O after O 12 O weeks O without O methimazole B-Chemical . O In O rare O cases O within O the O first O few O weeks O of O therapy O , O this O drug O can O cause O severe O and O reversible O cholestatic B-Disease jaundice I-Disease . O Physicians O and O patients O should O be O aware O of O this O adverse O effect O so O that O , O upon O occurrence O , O they O can O discontinue O methimazole B-Chemical therapy O and O avoid O unnecessary O invasive O procedures O . O Atrial B-Disease fibrillation I-Disease following O chemotherapy O for O stage O IIIE O diffuse O large O B O - O cell O gastric B-Disease lymphoma I-Disease in O a O patient O with O myotonic B-Disease dystrophy I-Disease ( O Steinert B-Disease ' I-Disease s I-Disease disease I-Disease ) O . O The O authors O describe O the O unusual O association O between O diffuse O B O - O cell O gastric B-Disease lymphoma I-Disease and O myotonic B-Disease dystrophy I-Disease , O the O most O common O form O of O adult O muscular B-Disease dystrophy I-Disease , O and O sudden O atrial B-Disease fibrillation I-Disease following O one O cycle O of O doxorubicin B-Chemical - O based O chemotherapy O in O the O same O patient O . O Atrial B-Disease fibrillation I-Disease or O other O cardiac B-Disease arrhythmias I-Disease are O unusual O complications O in O patients O treated O with O chemotherapy O . O The O cardiac B-Disease toxicity I-Disease intrinsically O associated O with O the O aggressive O chemotherapy O employed O could O function O as O a O triggering O factor O for O the O arrhythmia B-Disease in O the O predisposed O myocardium O of O this O patient O . O Hypersensitivity B-Disease immune O reaction O as O a O mechanism O for O dilevalol B-Chemical - O associated O hepatitis B-Disease . O OBJECTIVE O : O To O assess O lymphocyte O reactivity O to O dilevalol B-Chemical and O to O serum O containing O putative O ex O vivo O dilevalol B-Chemical antigens O or O metabolites O in O a O case O of O dilevalol B-Chemical - O induced O liver B-Disease injury I-Disease . O PATIENT O : O A O 58 O - O year O - O old O woman O with O a O clinical O diagnosis O of O dilevalol B-Chemical - O induced O liver B-Disease injury I-Disease . O METHODS O : O Peripheral O blood O mononuclear O cells O collected O from O the O patient O were O cultured O in O the O presence O of O a O solution O of O dilevalol B-Chemical and O also O with O sera O collected O from O a O volunteer O before O and O after O dilevalol B-Chemical intake O . O A O similar O protocol O was O performed O with O lymphocytes O from O a O healthy O subject O . O RESULTS O : O No O lymphocyte O proliferation O was O observed O either O in O the O patient O or O in O the O healthy O volunteer O in O the O presence O of O dilevalol B-Chemical solutions O . O A O significant O proliferative O response O to O serum O collected O after O dilevalol B-Chemical intake O was O observed O in O the O case O of O the O patient O compared O with O the O proliferative O response O to O the O serum O collected O before O the O drug O intake O . O No O reactivity O was O found O when O lymphocytes O from O the O healthy O subject O were O tested O under O similar O conditions O . O CONCLUSIONS O : O The O methodology O used O allowed O the O detection O of O lymphocyte O sensitization O to O sera O containing O ex O vivo O - O prepared O dilevalol B-Chemical antigens O , O suggesting O the O involvement O of O an O immunologic O mechanism O in O dilevalol B-Chemical - O induced O liver B-Disease injury I-Disease . O Increased O expression O and O apical O targeting O of O renal O ENaC O subunits O in O puromycin B-Chemical aminonucleoside I-Chemical - O induced O nephrotic B-Disease syndrome I-Disease in O rats O . O Nephrotic B-Disease syndrome I-Disease is O often O accompanied O by O sodium B-Chemical retention O and O generalized O edema B-Disease . O However O , O the O molecular O basis O for O the O decreased O renal O sodium B-Chemical excretion O remains O undefined O . O We O hypothesized O that O epithelial O Na B-Chemical channel O ( O ENaC O ) O subunit O dysregulation O may O be O responsible O for O the O increased O sodium B-Chemical retention O . O An O experimental O group O of O rats O was O treated O with O puromycin B-Chemical aminonucleoside I-Chemical ( O PAN B-Chemical ; O 180 O mg O / O kg O iv O ) O , O whereas O the O control O group O received O only O vehicle O . O After O 7 O days O , O PAN B-Chemical treatment O induced O significant O proteinuria B-Disease , O hypoalbuminemia B-Disease , O decreased O urinary O sodium B-Chemical excretion O , O and O extensive O ascites B-Disease . O The O protein O abundance O of O alpha O - O ENaC O and O beta O - O ENaC O was O increased O in O the O inner O stripe O of O the O outer O medulla O ( O ISOM O ) O and O in O the O inner O medulla O ( O IM O ) O but O was O not O altered O in O the O cortex O . O gamma O - O ENaC O abundance O was O increased O in O the O cortex O , O ISOM O , O and O IM O . O Immunoperoxidase O brightfield O - O and O laser O - O scanning O confocal O fluorescence O microscopy O demonstrated O increased O targeting O of O alpha O - O ENaC O , O beta O - O ENaC O , O and O gamma O - O ENaC O subunits O to O the O apical O plasma O membrane O in O the O distal O convoluted O tubule O ( O DCT2 O ) O , O connecting O tubule O , O and O cortical O and O medullary O collecting O duct O segments O . O Immunoelectron O microscopy O further O revealed O an O increased O labeling O of O alpha O - O ENaC O in O the O apical O plasma O membrane O of O cortical O collecting O duct O principal O cells O of O PAN B-Chemical - O treated O rats O , O indicating O enhanced O apical O targeting O of O alpha O - O ENaC O subunits O . O In O contrast O , O the O protein O abundances O of O Na B-Chemical ( O + O ) O / O H B-Chemical ( O + O ) O exchanger O type O 3 O ( O NHE3 O ) O , O Na B-Chemical ( O + O ) O - O K B-Chemical ( O + O ) O - O 2Cl B-Chemical ( O - O ) O cotransporter O ( O BSC O - O 1 O ) O , O and O thiazide B-Chemical - O sensitive O Na B-Chemical ( O + O ) O - O Cl B-Chemical ( O - O ) O cotransporter O ( O TSC O ) O were O decreased O . O Moreover O , O the O abundance O of O the O alpha O ( O 1 O ) O - O subunit O of O the O Na B-Chemical - O K B-Chemical - O ATPase O was O decreased O in O the O cortex O and O ISOM O , O but O it O remained O unchanged O in O the O IM O . O In O conclusion O , O the O increased O or O sustained O expression O of O ENaC O subunits O combined O with O increased O apical O targeting O in O the O DCT2 O , O connecting O tubule O , O and O collecting O duct O are O likely O to O play O a O role O in O the O sodium B-Chemical retention O associated O with O PAN B-Chemical - O induced O nephrotic B-Disease syndrome I-Disease . O The O decreased O abundance O of O NHE3 O , O BSC O - O 1 O , O TSC O , O and O Na B-Chemical - O K B-Chemical - O ATPase O may O play O a O compensatory O role O to O promote O sodium B-Chemical excretion O . O Pallidal O stimulation O : O an O alternative O to O pallidotomy O ? O A O resurgence O of O interest O in O the O surgical O treatment O of O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease ( O PD B-Disease ) O came O with O the O rediscovery O of O posteroventral O pallidotomy O by O Laitinen O in O 1985 O . O Laitinen O ' O s O procedure O improved O most O symptoms O in O drug O - O resistant O PD B-Disease , O which O engendered O wide O interest O in O the O neurosurgical O community O . O Another O lesioning O procedure O , O ventrolateral O thalamotomy O , O has O become O a O powerful O alternative O to O stimulate O the O nucleus O ventralis O intermedius O , O producing O high O long O - O term O success O rates O and O low O morbidity O rates O . O Pallidal O stimulation O has O not O met O with O the O same O success O . O According O to O the O literature O pallidotomy O improves O the O " O on O " O symptoms O of O PD B-Disease , O such O as O dyskinesias B-Disease , O as O well O as O the O " O off O " O symptoms O , O such O as O rigidity B-Disease , O bradykinesia B-Disease , O and O on O - O off O fluctuations O . O Pallidal O stimulation O improves O bradykinesia B-Disease and O rigidity B-Disease to O a O minor O extent O ; O however O , O its O strength O seems O to O be O in O improving O levodopa B-Chemical - O induced O dyskinesias B-Disease . O Stimulation O often O produces O an O improvement O in O the O hyper B-Disease - I-Disease or I-Disease dyskinetic I-Disease upper O limbs O , O but O increases O the O " O freezing O " O phenomenon O in O the O lower O limbs O at O the O same O time O . O Considering O the O small O increase O in O the O patient O ' O s O independence O , O the O high O costs O of O bilateral O implants O , O and O the O difficulty O most O patients O experience O in O handling O the O devices O , O the O question O arises O as O to O whether O bilateral O pallidal O stimulation O is O a O real O alternative O to O pallidotomy O . O Effects O of O the O cyclooxygenase O - O 2 O specific O inhibitor O valdecoxib B-Chemical versus O nonsteroidal O antiinflammatory O agents O and O placebo O on O cardiovascular O thrombotic B-Disease events O in O patients O with O arthritis B-Disease . O There O have O been O concerns O that O the O risk O of O cardiovascular O thrombotic B-Disease events O may O be O higher O with O cyclooxygenase O ( O COX O ) O - O 2 O - O specific O inhibitors O than O nonselective O nonsteroidal O antiinflammatory O drugs O ( O NSAIDs O ) O . O We O evaluated O cardiovascular O event O data O for O valdecoxib B-Chemical , O a O new O COX O - O 2 O - O specific O inhibitor O in O approximately O 8000 O patients O with O osteoarthritis B-Disease and O rheumatoid B-Disease arthritis I-Disease treated O with O this O agent O in O randomized O clinical O trials O . O The O incidence O of O cardiovascular O thrombotic B-Disease events O ( O cardiac O , O cerebrovascular O and O peripheral O vascular O , O or O arterial O thrombotic B-Disease ) O was O determined O by O analyzing O pooled O valdecoxib B-Chemical ( O 10 O - O 80 O mg O daily O ) O , O nonselective O NSAID O ( O diclofenac B-Chemical 75 O mg O bid O , O ibuprofen B-Chemical 800 O mg O tid O , O or O naproxen B-Chemical 500 O mg O bid O ) O and O placebo O data O from O 10 O randomized O osteoarthritis B-Disease and O rheumatoid B-Disease arthritis I-Disease trials O that O were O 6 O - O 52 O weeks O in O duration O .

O The O 47 O - O year O - O old O female O patient O , O known O to O have O hypertrophic B-Disease cardiomyopathy I-Disease , O was O admitted O with O biventricular B-Disease failure I-Disease and O managed O aggressively O with O dobutamine B-Chemical infusion O and O other O drugs O while O being O assessed O for O heart O transplantation O . O On O transthoracic O echocardiogram O , O she O had O moderate O left B-Disease ventricular I-Disease dysfunction I-Disease with O regional O variability O and O moderate O mitral B-Disease regurgitation I-Disease . O The O recipient O ' O s O heart O showed O the O features O of O apical O hypertrophic B-Disease cardiomyopathy I-Disease and O myocarditis B-Disease with O abundant O eosinophils O . O Myocarditis B-Disease is O rare O and O eosinophilic B-Disease myocarditis I-Disease is O rarer O . O It O is O likely O that O the O hypersensitivity B-Disease ( O eosinophilic B-Disease ) O myocarditis B-Disease was O related O to O dobutamine B-Chemical infusion O therapy O .

O This O study O evaluated O yohimbine B-Chemical as O a O treatment O for O the O sexual B-Disease side I-Disease effects I-Disease caused O by O serotonin B-Chemical reuptake O blockers O . O METHOD O : O Six O patients O with O either O obsessive B-Disease compulsive I-Disease disorder I-Disease , O trichotillomania B-Disease , O anxiety B-Disease , O or O affective B-Disease disorders I-Disease who O suffered O sexual B-Disease side I-Disease effects I-Disease after O treatment O with O serotonin B-Chemical reuptake O blockers O were O given O yohimbine B-Chemical on O a O p O . O r O . O n O . O basis O in O an O open O clinical O trial O . O Various O doses O of O yohimbine B-Chemical were O used O to O determine O the O ideal O dose O for O each O patient O . O RESULTS O : O Five O of O the O six O patients O experienced O improved O sexual O functioning O after O taking O yohimbine B-Chemical . O One O patient O who O failed O to O comply O with O yohimbine B-Chemical treatment O had O no O therapeutic O effects O . O Side O effects O of O yohimbine B-Chemical included O excessive O sweating O , O increased O anxiety B-Disease , O and O a O wound O - O up O feeling O in O some O patients O . O CONCLUSION O : O The O results O of O this O study O indicate O that O yohimbine B-Chemical may O be O an O effective O treatment O for O the O sexual B-Disease side I-Disease effects I-Disease caused O by O serotonin B-Chemical reuptake O blockers O . O Future O controlled O studies O are O needed O to O further O investigate O the O effectiveness O and O safety O of O yohimbine B-Chemical for O this O indication O . O Hemorrhagic B-Disease cystitis I-Disease complicating O bone O marrow O transplantation O . O Hemorrhagic B-Disease cystitis I-Disease is O a O potentially O serious O complication O of O high O - O dose O cyclophosphamide B-Chemical therapy O administered O before O bone O marrow O transplantation O . O As O standard O practice O at O our O institution O , O patients O who O are O scheduled O to O receive O a O bone O marrow O transplant O are O treated O prophylactically O with O forced O hydration O and O bladder O irrigation O . O In O an O attempt O to O obviate O the O inconvenience O of O bladder O irrigation O , O we O conducted O a O feasibility O trial O of O uroprophylaxis O with O mesna B-Chemical , O which O neutralizes O the O hepatic O metabolite O of O cyclophosphamide B-Chemical that O causes O hemorrhagic B-Disease cystitis I-Disease . O Of O 97 O patients O who O received O standard O prophylaxis O , O 4 O had O symptomatic O hemorrhagic B-Disease cystitis I-Disease . O In O contrast O , O two O of O four O consecutive O patients O who O received O mesna B-Chemical uroprophylaxis O before O allogeneic O bone O marrow O transplantation O had O severe O hemorrhagic B-Disease cystitis I-Disease for O at O least O 2 O weeks O . O Because O of O this O suboptimal O result O , O we O resumed O the O use O of O bladder O irrigation O and O forced O hydration O to O minimize O the O risk O of O hemorrhagic B-Disease cystitis I-Disease . O Consensus O statement O concerning O cardiotoxicity B-Disease occurring O during O haematopoietic O stem O cell O transplantation O in O the O treatment O of O autoimmune B-Disease diseases I-Disease , O with O special O reference O to O systemic B-Disease sclerosis I-Disease and O multiple B-Disease sclerosis I-Disease . O Autologous O haematopoietic O stem O cell O transplantation O is O now O a O feasible O and O effective O treatment O for O selected O patients O with O severe O autoimmune B-Disease diseases I-Disease . O Worldwide O , O over O 650 O patients O have O been O transplanted O in O the O context O of O phase O I O and O II O clinical O trials O . O The O results O are O encouraging O enough O to O begin O randomised O phase O III O trials O . O However O , O as O predicted O , O significant O transplant O - O related O morbidity O and O mortality O have O been O observed O . O This O is O primarily O due O to O complications O related O to O either O the O stage O of O the O disease O at O transplant O or O due O to O infections B-Disease . O The O number O of O deaths O related O to O cardiac B-Disease toxicity I-Disease is O low O . O However O , O caution O is O required O when O cyclophosphamide B-Chemical or O anthracyclines B-Chemical such O as O mitoxantrone B-Chemical are O used O in O patients O with O a O possible O underlying O heart B-Disease damage I-Disease , O for O example O , O systemic B-Disease sclerosis I-Disease patients O . O In O November O 2002 O , O a O meeting O was O held O in O Florence O , O bringing O together O a O number O of O experts O in O various O fields O , O including O rheumatology O , O cardiology O , O neurology O , O pharmacology O and O transplantation O medicine O . O The O object O of O the O meeting O was O to O analyse O existing O data O , O both O published O or O available O , O in O the O European O Group O for O Blood O and O Marrow O Transplantation O autoimmune B-Disease disease I-Disease database O , O and O to O propose O a O safe O approach O to O such O patients O . O A O full O cardiological O assessment O before O and O during O the O transplant O emerged O as O the O major O recommendation O . O Does O supplemental O vitamin B-Chemical C I-Chemical increase O cardiovascular B-Disease disease I-Disease risk O in O women O with O diabetes B-Disease ? O BACKGROUND O : O Vitamin B-Chemical C I-Chemical acts O as O a O potent O antioxidant O ; O however O , O it O can O also O be O a O prooxidant O and O glycate O protein O under O certain O circumstances O in O vitro O . O These O observations O led O us O to O hypothesize O that O a O high O intake O of O vitamin B-Chemical C I-Chemical in O diabetic B-Disease persons O might O promote O atherosclerosis B-Disease . O OBJECTIVE O : O The O objective O was O to O examine O the O relation O between O vitamin B-Chemical C I-Chemical intake O and O mortality O from O cardiovascular B-Disease disease I-Disease . O DESIGN O : O We O studied O the O relation O between O vitamin B-Chemical C I-Chemical intake O and O mortality O from O total O cardiovascular B-Disease disease I-Disease ( O n O = O 281 O ) O , O coronary B-Disease artery I-Disease disease I-Disease ( O n O = O 175 O ) O , O and O stroke B-Disease ( O n O = O 57 O ) O in O 1923 O postmenopausal O women O who O reported O being O diabetic B-Disease at O baseline O . O Diet O was O assessed O with O a O food O - O frequency O questionnaire O at O baseline O , O and O subjects O initially O free O of O coronary B-Disease artery I-Disease disease I-Disease were O prospectively O followed O for O 15 O y O . O RESULTS O : O After O adjustment O for O cardiovascular B-Disease disease I-Disease risk O factors O , O type O of O diabetes B-Disease medication O used O , O duration O of O diabetes B-Disease , O and O intakes O of O folate B-Chemical , O vitamin B-Chemical E I-Chemical , O and O beta B-Chemical - I-Chemical carotene I-Chemical , O the O adjusted O relative O risks O of O total O cardiovascular B-Disease disease I-Disease mortality O were O 1 O . O 0 O , O 0 O . O 97 O , O 1 O . O 11 O , O 1 O . O 47 O , O and O 1 O . O 84 O ( O P O for O trend O < O 0 O . O 01 O ) O across O quintiles O of O total O vitamin B-Chemical C I-Chemical intake O from O food O and O supplements O . O Adjusted O relative O risks O of O coronary B-Disease artery I-Disease disease I-Disease were O 1 O . O 0 O , O 0 O . O 81 O , O 0 O . O 99 O , O 1 O . O 26 O , O and O 1 O . O 91 O ( O P O for O trend O = O 0 O . O 01 O ) O and O of O stroke B-Disease were O 1 O . O 0 O , O 0 O . O 52 O , O 1 O . O 23 O , O 2 O . O 22 O , O and O 2 O . O 57 O ( O P O for O trend O < O 0 O . O 01 O ) O . O When O dietary O and O supplemental O vitamin B-Chemical C I-Chemical were O analyzed O separately O , O only O supplemental O vitamin B-Chemical C I-Chemical showed O a O positive O association O with O mortality O endpoints O . O Vitamin B-Chemical C I-Chemical intake O was O unrelated O to O mortality O from O cardiovascular B-Disease disease I-Disease in O the O nondiabetic O subjects O at O baseline O . O CONCLUSION O : O A O high O vitamin B-Chemical C I-Chemical intake O from O supplements O is O associated O with O an O increased O risk O of O cardiovascular B-Disease disease I-Disease mortality O in O postmenopausal O women O with O diabetes B-Disease . O Optical O coherence O tomography O can O measure O axonal O loss O in O patients O with O ethambutol B-Chemical - O induced O optic B-Disease neuropathy I-Disease . O PURPOSE O : O To O map O and O identify O the O pattern O , O in O vivo O , O of O axonal B-Disease degeneration I-Disease in O ethambutol B-Chemical - O induced O optic B-Disease neuropathy I-Disease using O optical O coherence O tomography O ( O OCT O ) O . O Ethambutol B-Chemical is O an O antimycobacterial O agent O often O used O to O treat O tuberculosis B-Disease . O A O serious O complication O of O ethambutol B-Chemical is O an O optic B-Disease neuropathy I-Disease that O impairs O visual O acuity O , O contrast O sensitivity O , O and O color O vision O . O However O , O early O on O , O when O the O toxic O optic B-Disease neuropathy I-Disease is O mild O and O partly O reversible O , O the O funduscopic O findings O are O often O subtle O and O easy O to O miss O . O METHODS O : O Three O subjects O with O a O history O of O ethambutol B-Chemical ( O EMB B-Chemical ) O - O induced O optic B-Disease neuropathy I-Disease of O short O - O , O intermediate O - O , O and O long O - O term O visual B-Disease deficits I-Disease were O administered O a O full O neuro O - O ophthalmologic O examination O including O visual O acuity O , O color O vision O , O contrast O sensitivity O , O and O fundus O examination O . O In O addition O , O OCT O ( O OCT O 3000 O , O Humphrey O - O Zeiss O , O Dublin O , O CA O ) O was O performed O on O both O eyes O of O each O subject O using O the O retinal O nerve O fiber O layer O ( O RNFL O ) O analysis O protocol O . O OCT O interpolates O data O from O 100 O points O around O the O optic O nerve O to O effectively O map O out O the O RNFL O . O RESULTS O : O The O results O were O compared O to O the O calculated O average O RNFL O of O normal O eyes O accumulated O from O four O prior O studies O using O OCT O , O n O = O 661 O . O In O all O subjects O with O history O of O EMB B-Chemical - O induced O optic B-Disease neuropathy I-Disease , O there O was O a O mean O loss O of O 72 O % O nerve O fiber O layer O thickness O in O the O temporal O quadrant O ( O patient O A O , O with O eventual O recovery O of O visual O acuity O and O fields O , O 58 O % O loss O ; O patient O B O , O with O intermediate O visual B-Disease deficits I-Disease , O 68 O % O loss O ; O patient O C O , O with O chronic O visual B-Disease deficits I-Disease , O 90 O % O loss O ) O , O with O an O average O mean O optic O nerve O thickness O of O 26 O + O / O - O 16 O microm O . O There O was O a O combined O mean O loss O of O 46 O % O of O fibers O from O the O superior O , O inferior O , O and O nasal O quadrants O in O the O ( O six O ) O eyes O of O all O three O subjects O ( O mean O average O thickness O of O 55 O + O / O - O 29 O microm O ) O . O In O both O sets O ( O four O ) O of O eyes O of O the O subjects O with O persistent O visual B-Disease deficits I-Disease ( O patients O B O and O C O ) O , O there O was O an O average O loss O of O 79 O % O of O nerve O fiber O thickness O in O the O temporal O quadrant O . O CONCLUSIONS O : O The O OCT O results O in O these O patients O with O EMB B-Chemical - O induced O optic B-Disease neuropathy I-Disease show O considerable O loss O especially O of O the O temporal O fibers O . O This O is O consistent O with O prior O histopathological O studies O that O show O predominant O loss O of O parvo O - O cellular O axons O ( O or O small O - O caliber O axons O ) O within O the O papillo O - O macular O bundle O in O toxic O or O hereditary O optic B-Disease neuropathies I-Disease . O OCT O can O be O a O valuable O tool O in O the O quantitative O analysis O of O optic B-Disease neuropathies I-Disease . O Additionally O , O in O terms O of O management O of O EMB B-Chemical - O induced O optic B-Disease neuropathy I-Disease , O it O is O important O to O properly O manage O ethambutol B-Chemical dosing O in O patients O with O renal B-Disease impairment I-Disease and O to O achieve O proper O transition O to O a O maintenance O dose O once O an O appropriate O loading O dose O has O been O reached O . O Hypoxia B-Disease in O renal B-Disease disease I-Disease with O proteinuria B-Disease and O / O or O glomerular O hypertension B-Disease . O Despite O the O increasing O need O to O identify O and O quantify O tissue O oxygenation O at O the O cellular O level O , O relatively O few O methods O have O been O available O . O In O this O study O , O we O developed O a O new O hypoxia B-Disease - O responsive O reporter O vector O using O a O hypoxia B-Disease - O responsive O element O of O the O 5 O ' O vascular O endothelial O growth O factor O untranslated O region O and O generated O a O novel O hypoxia B-Disease - O sensing O transgenic O rat O . O We O then O applied O this O animal O model O to O the O detection O of O tubulointerstitial O hypoxia B-Disease in O the O diseased B-Disease kidney I-Disease . O With O this O model O , O we O were O able O to O identify O diffuse O cortical O hypoxia B-Disease in O the O puromycin B-Chemical aminonucleoside I-Chemical - O induced O nephrotic B-Disease syndrome I-Disease and O focal O and O segmental O hypoxia B-Disease in O the O remnant O kidney O model O . O Expression O of O the O hypoxia B-Disease - O responsive O transgene O increased O throughout O the O observation O period O , O reaching O 2 O . O 2 O - O fold O at O 2 O weeks O in O the O puromycin B-Chemical aminonucleoside I-Chemical model O and O 2 O . O 6 O - O fold O at O 4 O weeks O in O the O remnant O kidney O model O , O whereas O that O of O vascular O endothelial O growth O factor O showed O a O mild O decrease O , O reflecting O distinct O behaviors O of O the O two O genes O . O The O degree O of O hypoxia B-Disease showed O a O positive O correlation O with O microscopic O tubulointerstitial B-Disease injury I-Disease in O both O models O . O Finally O , O we O identified O the O localization O of O proliferating O cell O nuclear O antigen O - O positive O , O ED O - O 1 O - O positive O , O and O terminal O dUTP O nick O - O end O labeled O - O positive O cells O in O the O hypoxic B-Disease cortical O area O in O the O remnant O kidney O model O . O We O propose O here O a O possible O pathological O tie O between O chronic O tubulointerstitial O hypoxia B-Disease and O progressive O glomerular B-Disease diseases I-Disease . O Adequate O timing O of O ribavirin B-Chemical reduction O in O patients O with O hemolysis B-Disease during O combination O therapy O of O interferon B-Chemical and O ribavirin B-Chemical for O chronic B-Disease hepatitis I-Disease C I-Disease . O BACKGROUND O : O Hemolytic B-Disease anemia I-Disease is O one O of O the O major O adverse O events O of O the O combination O therapy O of O interferon B-Chemical and O ribavirin B-Chemical . O Because O of O ribavirin B-Chemical - O related O hemolytic B-Disease anemia I-Disease , O dose O reduction O is O a O common O event O in O this O therapy O . O In O this O clinical O retrospective O cohort O study O we O have O examined O the O suitable O timing O of O ribavirin B-Chemical reduction O in O patients O with O hemolysis B-Disease during O combination O therapy O . O METHODS O : O Thirty O - O seven O of O 160 O patients O who O had O HCV O - O genotype O 1b O , O had O high O virus O load O , O and O received O 24 O - O week O combination O therapy O developed O anemia B-Disease with O hemoglobin O level O < O 10 O g O / O dl O or O anemia B-Disease - O related O signs O during O therapy O . O After O that O , O these O 37 O patients O were O reduced O one O tablet O of O ribavirin B-Chemical ( O 200 O mg O ) O per O day O . O After O reduction O of O ribavirin B-Chemical , O 27 O of O 37 O patients O could O continue O combination O therapy O for O a O total O of O 24 O weeks O ( O group O A O ) O . O However O , O 10 O of O 37 O patients O with O reduction O of O ribavirin B-Chemical could O not O continue O combination O therapy O because O their O < O 8 O . O 5 O g O / O dl O hemoglobin O values O decreased O to O or O anemia B-Disease - O related O severe O side O effects O occurred O ( O group O B O ) O . O We O assessed O the O final O efficacy O and O safety O after O reduction O of O ribavirin B-Chemical in O groups O A O and O B O . O RESULTS O : O A O sustained O virological O response O ( O SVR O ) O was O 29 O . O 6 O % O ( O 8 O / O 27 O ) O in O group O A O and O 10 O % O ( O 1 O / O 10 O ) O in O group O B O , O respectively O . O A O 34 O . O 4 O % O ( O 12 O / O 27 O ) O of O SVR O + O biological O response O in O group O A O was O higher O than O 10 O % O ( O 1 O / O 10 O ) O in O group O B O ( O P O = O 0 O . O 051 O ) O , O with O slight O significance O . O With O respect O to O hemoglobin O level O at O the O time O of O ribavirin B-Chemical reduction O , O a O rate O of O continuation O of O therapy O in O patients O with O > O or O = O 10 O g O / O dl O hemoglobin O was O higher O than O that O in O patients O with O < O 10 O g O / O dl O ( O P O = O 0 O . O 036 O ) O . O CONCLUSIONS O : O Reduction O of O ribavirin B-Chemical at O hemoglobin O level O > O or O = O 10 O g O / O dl O is O suitable O in O terms O of O efficacy O and O side O effects O . O Aging O process O of O epithelial O cells O of O the O rat O prostate O lateral O lobe O in O experimental O hyperprolactinemia B-Disease induced O by O haloperidol B-Chemical . O The O aim O of O the O study O was O to O examine O the O influence O of O hyperprolactinemia B-Disease , O induced O by O haloperidol B-Chemical ( O HAL B-Chemical ) O on O age O related O morphology O and O function O changes O of O epithelial O cells O in O rat O prostate O lateral O lobe O . O The O study O was O performed O on O sexually O mature O male O rats O . O Serum O concentrations O of O prolactin O ( O PRL B-Chemical ) O and O testosterone B-Chemical ( O T B-Chemical ) O were O measured O . O Tissue O sections O were O evaluated O with O light O and O electron O microscopy O . O Immunohistochemical O reactions O for O Anti O - O Proliferating O Cell O Nuclear O Antigen O ( O PCNA O ) O were O performed O . O In O rats O of O the O experimental O group O , O the O mean O concentration O of O : O PRL B-Chemical was O more O than O twice O higher O , O whereas O T B-Chemical concentration O was O almost O twice O lower O than O that O in O the O control O group O . O Light O microscopy O visualized O the O following O : O hypertrophy B-Disease and O epithelium O hyperplasia B-Disease of O the O glandular O ducts O , O associated O with O increased O PCNA O expression O . O Electron O microscopy O revealed O changes O in O columnar O epithelial O cells O , O concerning O organelles O , O engaged O in O protein O synthesis O and O secretion O . O Relation O of O perfusion O defects O observed O with O myocardial O contrast O echocardiography O to O the O severity O of O coronary B-Disease stenosis I-Disease : O correlation O with O thallium B-Chemical - O 201 O single O - O photon O emission O tomography O . O It O has O been O previously O shown O that O myocardial O contrast O echocardiography O is O a O valuable O technique O for O delineating O regions O of O myocardial O underperfusion O secondary O to O coronary B-Disease occlusion I-Disease and O to O critical O coronary B-Disease stenoses I-Disease in O the O presence O of O hyperemic B-Disease stimulation O . O The O aim O of O this O study O was O to O determine O whether O myocardial O contrast O echocardiography O performed O with O a O stable O solution O of O sonicated O albumin O could O detect O regions O of O myocardial O underperfusion O resulting O from O various O degrees O of O coronary B-Disease stenosis I-Disease . O The O perfusion O defect O produced O in O 16 O open O chest O dogs O was O compared O with O the O anatomic O area O at O risk O measured O by O the O postmortem O dual O - O perfusion O technique O and O with O thallium B-Chemical - O 201 O single O - O photon O emission O tomography O ( O SPECT O ) O . O During O a O transient O ( O 20 O - O s O ) O coronary B-Disease occlusion I-Disease , O a O perfusion O defect O was O observed O with O contrast O echocardiography O in O 14 O of O the O 15 O dogs O in O which O the O occlusion O was O produced O . O The O perfusion O defect O correlated O significantly O with O the O anatomic O area O at O risk O ( O r O = O 0 O . O 74 O ; O p O less O than O 0 O . O 002 O ) O . O During O dipyridamole B-Chemical - O induced O hyperemia B-Disease , O 12 O of O the O 16 O dogs O with O a O partial O coronary B-Disease stenosis I-Disease had O a O visible O area O of O hypoperfusion O by O contrast O echocardiography O . O The O four O dogs O without O a O perfusion O defect O had O a O stenosis O that O resulted O in O a O mild O ( O 0 O % O to O 50 O % O ) O reduction O in O dipyridamole B-Chemical - O induced O hyperemia B-Disease . O The O size O of O the O perfusion O defect O during O stenosis O correlated O significantly O with O the O anatomic O area O at O risk O ( O r O = O 0 O . O 61 O ; O p O = O 0 O . O 02 O ) O . O Thallium B-Chemical - O 201 O SPECT O demonstrated O a O perfusion O defect O in O all O 14 O dogs O analyzed O during O dipyridamole B-Chemical - O induced O hyperemia B-Disease ; O the O size O of O the O perfusion O defect O correlated O with O the O anatomic O area O at O risk O ( O r O = O 0 O . O 58 O ; O p O less O than O 0 O . O 03 O ) O and O with O the O perfusion O defect O by O contrast O echocardiography O ( O r O = O 0 O . O 58 O ; O p O less O than O 0 O . O 03 O ) O . O Thus O , O myocardial O contrast O echocardiography O can O be O used O to O visualize O and O quantitate O the O amount O of O jeopardized O myocardium O during O moderate O to O severe O degrees O of O coronary B-Disease stenosis I-Disease . O The O results O obtained O show O a O correlation O with O the O anatomic O area O at O risk O similar O to O that O obtained O with O thallium B-Chemical - O 201 O SPECT O . O The O activation O of O spinal O N B-Chemical - I-Chemical methyl I-Chemical - I-Chemical D I-Chemical - I-Chemical aspartate I-Chemical receptors O may O contribute O to O degeneration O of O spinal O motor O neurons O induced O by O neuraxial O morphine B-Chemical after O a O noninjurious O interval O of O spinal B-Disease cord I-Disease ischemia I-Disease . O We O investigated O the O relationship O between O the O degeneration O of O spinal O motor O neurons O and O activation O of O N B-Chemical - I-Chemical methyl I-Chemical - I-Chemical d I-Chemical - I-Chemical aspartate I-Chemical ( O NMDA B-Chemical ) O receptors O after O neuraxial O morphine B-Chemical following O a O noninjurious O interval O of O aortic B-Disease occlusion I-Disease in O rats O . O Spinal B-Disease cord I-Disease ischemia I-Disease was O induced O by O aortic B-Disease occlusion I-Disease for O 6 O min O with O a O balloon O catheter O . O In O a O microdialysis O study O , O 10 O muL O of O saline O ( O group O C O ; O n O = O 8 O ) O or O 30 O mug O of O morphine B-Chemical ( O group O M O ; O n O = O 8 O ) O was O injected O intrathecally O ( O IT O ) O 0 O . O 5 O h O after O reflow O , O and O 30 O mug O of O morphine B-Chemical ( O group O SM O ; O n O = O 8 O ) O or O 10 O muL O of O saline O ( O group O SC O ; O n O = O 8 O ) O was O injected O IT O 0 O . O 5 O h O after O sham O operation O . O Microdialysis O samples O were O collected O preischemia O , O before O IT O injection O , O and O at O 2 O , O 4 O , O 8 O , O 24 O , O and O 48 O h O of O reperfusion O ( O after O IT O injection O ) O . O Second O , O we O investigated O the O effect O of O IT O MK B-Chemical - I-Chemical 801 I-Chemical ( O 30 O mug O ) O on O the O histopathologic O changes O in O the O spinal O cord O after O morphine B-Chemical - O induced O spastic B-Disease paraparesis I-Disease . O After O IT O morphine B-Chemical , O the O cerebrospinal O fluid O ( O CSF O ) O glutamate B-Chemical concentration O was O increased O in O group O M O relative O to O both O baseline O and O group O C O ( O P O < O 0 O . O 05 O ) O . O This O increase O persisted O for O 8 O hrs O . O IT O MK B-Chemical - I-Chemical 801 I-Chemical significantly O reduced O the O number O of O dark O - O stained O alpha O - O motoneurons O after O morphine B-Chemical - O induced O spastic B-Disease paraparesis I-Disease compared O with O the O saline O group O . O These O data O indicate O that O IT O morphine B-Chemical induces O spastic B-Disease paraparesis I-Disease with O a O concomitant O increase O in O CSF O glutamate B-Chemical , O which O is O involved O in O NMDA B-Chemical receptor O activation O . O We O suggest O that O opioids O may O be O neurotoxic B-Disease in O the O setting O of O spinal B-Disease cord I-Disease ischemia I-Disease via O NMDA B-Chemical receptor O activation O . O Acute O low B-Disease back I-Disease pain I-Disease during O intravenous O administration O of O amiodarone B-Chemical : O a O report O of O two O cases O . O Amiodarone B-Chemical represents O an O effective O antiarrhythmic O drug O for O cardioversion O of O recent O - O onset O atrial B-Disease fibrillation I-Disease ( O AF B-Disease ) O and O maintenance O of O sinus O rhythm O . O We O briefly O describe O two O patients O suffering O from O recent O - O onset O atrial B-Disease fibrillation I-Disease , O who O experienced O an O acute O devastating O low B-Disease back I-Disease pain I-Disease a O few O minutes O after O initiation O of O intravenous O amiodarone B-Chemical loading O . O Notably O , O this O side O effect O has O not O been O ever O reported O in O the O medical O literature O . O Clinicians O should O be O aware O of O this O reaction O since O prompt O termination O of O parenteral O administration O leads O to O complete O resolution O . O Quantitative O drug O levels O in O stimulant O psychosis B-Disease : O relationship O to O symptom O severity O , O catecholamines B-Chemical and O hyperkinesia B-Disease . O To O examine O the O relationship O between O quantitative O stimulant O drug O levels O , O catecholamines B-Chemical , O and O psychotic B-Disease symptoms I-Disease , O nineteen O patients O in O a O psychiatric B-Disease emergency O service O with O a O diagnosis O of O amphetamine B-Chemical - O or O cocaine B-Chemical - O induced O psychosis B-Disease were O interviewed O , O and O plasma O and O urine O were O collected O for O quantitative O assays O of O stimulant O drug O and O catecholamine B-Chemical metabolite O levels O . O Methamphetamine B-Chemical or O amphetamine B-Chemical levels O were O related O to O several O psychopathology O scores O and O the O global O hyperkinesia B-Disease rating O .

O Assessment O of O perinatal O hepatitis B-Disease B I-Disease and O rubella B-Disease prevention O in O New O Hampshire O delivery O hospitals O . O OBJECTIVE O : O To O evaluate O current O performance O on O recommended O perinatal O hepatitis B-Disease B I-Disease and O rubella B-Disease prevention O practices O in O New O Hampshire O . O METHODS O : O Data O were O extracted O from O 2021 O paired O mother O - O infant O records O for O the O year O 2000 O birth O cohort O in O New O Hampshire O ' O s O 25 O delivery O hospitals O . O Assessment O was O done O on O the O following O : O prenatal O screening O for O hepatitis B-Disease B I-Disease and O rubella B-Disease , O administration O of O the O hepatitis B-Disease B I-Disease vaccine O birth O dose O to O all O infants O , O administration O of O hepatitis B-Disease B I-Disease immune O globulin O to O infants O who O were O born O to O hepatitis B-Chemical B I-Chemical surface I-Chemical antigen I-Chemical - O positive O mothers O , O rubella B-Disease immunity O , O and O administration O of O in O - O hospital O postpartum O rubella B-Disease vaccine O to O rubella B-Disease nonimmune O women O . O RESULTS O : O Prenatal O screening O rates O for O hepatitis B-Disease B I-Disease ( O 98 O . O 8 O % O ) O and O rubella B-Disease ( O 99 O . O 4 O % O ) O were O high O . O Hepatitis B-Disease B I-Disease vaccine O birth O dose O was O administered O to O 76 O . O 2 O % O of O all O infants O . O All O infants O who O were O born O to O hepatitis B-Chemical B I-Chemical surface I-Chemical antigen I-Chemical - O positive O mothers O also O received O hepatitis B-Disease B I-Disease immune O globulin O . O Multivariate O logistic O regression O showed O that O the O month O of O delivery O and O infant O birth O weight O were O independent O predictors O of O hepatitis B-Disease B I-Disease vaccination O . O The O proportion O of O infants O who O were O vaccinated O in O January O and O February O 2000 O ( O 48 O . O 5 O % O and O 67 O .

O In O - O hospital O postpartum O rubella B-Disease vaccine O administration O was O documented O for O 75 O . O 6 O % O of O nonimmune O women O . O CONCLUSION O : O This O study O documents O good O compliance O in O New O Hampshire O ' O s O birthing O hospitals O with O national O guidelines O for O perinatal O hepatitis B-Disease B I-Disease and O rubella B-Disease prevention O and O highlights O potential O areas O for O improvement O . O Succinylcholine B-Chemical - O induced O masseter B-Disease muscle I-Disease rigidity I-Disease during O bronchoscopic O removal O of O a O tracheal O foreign O body O . O Masseter B-Disease muscle I-Disease rigidity I-Disease during O general O anesthesia O is O considered O an O early O warning O sign O of O a O possible O episode O of O malignant B-Disease hyperthermia I-Disease . O The O decision O whether O to O continue O or O discontinue O the O procedure O depends O on O the O urgency O of O the O surgery O and O severity O of O masseter B-Disease muscle I-Disease rigidity I-Disease . O Here O , O we O describe O a O case O of O severe O masseter B-Disease muscle I-Disease rigidity I-Disease ( O jaw B-Disease of I-Disease steel I-Disease ) O after O succinylcholine B-Chemical ( O Sch B-Chemical ) O administration O during O general O anesthetic O management O for O rigid O bronchoscopic O removal O of O a O tracheal O foreign O body O . O Anesthesia O was O continued O uneventfully O with O propofol B-Chemical infusion O while O all O facilities O were O available O to O detect O and O treat O malignant B-Disease hyperthermia I-Disease . O Dexrazoxane B-Chemical protects O against O myelosuppression B-Disease from O the O DNA O cleavage O - O enhancing O drugs O etoposide B-Chemical and O daunorubicin B-Chemical but O not O doxorubicin B-Chemical . O PURPOSE O : O The O anthracyclines B-Chemical daunorubicin B-Chemical and O doxorubicin B-Chemical and O the O epipodophyllotoxin B-Chemical etoposide B-Chemical are O potent O DNA O cleavage O - O enhancing O drugs O that O are O widely O used O in O clinical O oncology O ; O however O , O myelosuppression B-Disease and O cardiac B-Disease toxicity I-Disease limit O their O use O . O Dexrazoxane B-Chemical ( O ICRF B-Chemical - I-Chemical 187 I-Chemical ) O is O recommended O for O protection O against O anthracycline B-Chemical - O induced O cardiotoxicity B-Disease . O EXPERIMENTAL O DESIGN O : O Because O of O their O widespread O use O , O the O hematologic B-Disease toxicity I-Disease following O coadministration O of O dexrazoxane B-Chemical and O these O three O structurally O different O DNA O cleavage O enhancers O was O investigated O : O Sensitivity O of O human O and O murine O blood O progenitor O cells O to O etoposide B-Chemical , O daunorubicin B-Chemical , O and O doxorubicin B-Chemical + O / O - O dexrazoxane B-Chemical was O determined O in O granulocyte O - O macrophage O colony O forming O assays O . O Likewise O , O in O vivo O , O B6D2F1 O mice O were O treated O with O etoposide B-Chemical , O daunorubicin B-Chemical , O and O doxorubicin B-Chemical , O with O or O without O dexrazoxane B-Chemical over O a O wide O range O of O doses O : O posttreatment O , O a O full O hematologic O evaluation O was O done O . O RESULTS O : O Nontoxic O doses O of O dexrazoxane B-Chemical reduced O myelosuppression B-Disease and O weight B-Disease loss I-Disease from O daunorubicin B-Chemical and O etoposide B-Chemical in O mice O and O antagonized O their O antiproliferative O effects O in O the O colony O assay O ; O however O , O dexrazoxane B-Chemical neither O reduced O myelosuppression B-Disease , O weight B-Disease loss I-Disease , O nor O the O in O vitro O cytotoxicity B-Disease from O doxorubicin B-Chemical . O CONCLUSION O : O Although O our O findings O support O the O observation O that O dexrazoxane B-Chemical reduces O neither O hematologic O activity O nor O antitumor O activity O from O doxorubicin B-Chemical clinically O , O the O potent O antagonism O of O daunorubicin B-Chemical activity O raises O concern O ; O a O possible O interference O with O anticancer O efficacy O certainly O would O call O for O renewed O attention O . O Our O data O also O suggest O that O significant O etoposide B-Chemical dose O escalation O is O perhaps O possible O by O the O use O of O dexrazoxane B-Chemical . O Clinical O trials O in O patients O with O brain O metastases B-Disease combining O dexrazoxane B-Chemical and O high O doses O of O etoposide B-Chemical is O ongoing O with O the O aim O of O improving O efficacy O without O aggravating O hematologic B-Disease toxicity I-Disease . O If O successful O , O this O represents O an O exciting O mechanism O for O pharmacologic O regulation O of O side O effects O from O cytotoxic O chemotherapy O . O Assessment O of O the O onset O and O persistence O of O amnesia B-Disease during O procedural O sedation O with O propofol B-Chemical . O OBJECTIVES O : O To O assess O patients O ' O ability O to O repeat O and O recall O words O presented O to O them O while O undergoing O procedural O sedation O with O propofol B-Chemical , O and O correlate O their O recall O with O their O level O of O awareness O as O measured O by O bispectral O index O ( O BIS O ) O monitoring O . O METHODS O : O This O was O a O prospective O , O single O - O intervention O study O of O consenting O adult O patients O undergoing O procedural O sedation O with O propofol B-Chemical between O December O 28 O , O 2002 O , O and O October O 31 O , O 2003 O . O BIS O monitoring O was O initiated O starting O 3 O minutes O before O the O procedure O and O continuing O until O the O patient O had O regained O baseline O mental O status O . O At O 1 O - O minute O intervals O during O the O procedural O sedation O , O until O the O patient O regained O baseline O mental O status O at O the O end O of O the O procedure O , O a O word O from O a O standardized O list O was O read O aloud O , O and O the O patient O was O asked O to O immediately O repeat O the O word O to O the O investigator O . O The O BIS O score O at O the O time O the O word O was O read O and O the O patient O ' O s O ability O to O repeat O the O word O were O recorded O . O After O the O procedure O , O the O patient O was O asked O to O state O all O of O the O words O from O the O list O that O he O or O she O could O recall O , O and O to O identify O the O last O word O recalled O from O prior O to O the O start O of O the O procedure O and O the O first O word O recalled O from O after O the O procedure O was O completed O . O RESULTS O : O Seventy O - O five O consenting O patients O were O enrolled O ; O one O patient O was O excluded O from O data O analysis O for O a O protocol O violation O . O No O serious O adverse O events O were O noted O during O the O procedural O sedations O . O The O mean O ( O + O / O - O standard O deviation O ) O time O of O data O collection O was O 16 O . O 4 O minutes O ( O + O / O - O 7 O . O 1 O ; O range O 5 O to O 34 O minutes O ) O . O The O mean O initial O ( O preprocedure O ) O BIS O score O was O 97 O . O 1 O ( O + O / O - O 2 O . O 3 O ; O range O 92 O to O 99 O ) O . O The O mean O lowest O BIS O score O occurring O during O these O procedural O sedations O was O 66 O . O 9 O ( O + O / O - O 14 O . O 4 O ; O range O 33 O to O 91 O ) O . O The O mean O lowest O BIS O score O corresponding O to O the O ability O of O the O patient O to O immediately O repeat O words O read O from O the O list O was O 77 O . O 1 O ( O 95 O % O CI O = O 74 O . O 3 O to O 80 O . O 0 O ) O . O The O mean O highest O BIS O score O corresponding O to O the O inability B-Disease to I-Disease repeat I-Disease words I-Disease was O 81 O . O 5 O ( O 95 O % O CI O = O 78 O . O 1 O to O 84 O . O 8 O ) O . O The O mean O BIS O score O corresponding O to O the O last O word O recalled O from O prior O to O the O initiation O of O the O sedation O was O 96 O . O 7 O ( O + O / O - O 2 O . O 4 O ; O range O 84 O to O 98 O ) O . O The O mean O BIS O score O corresponding O to O the O first O word O recalled O after O the O procedure O was O completed O was O 91 O . O 2 O ( O 95 O % O CI O = O 88 O . O 1 O to O 94 O . O 3 O ) O . O All O patients O recalled O at O least O one O word O that O had O been O read O to O them O during O the O protocol O . O The O mean O lowest O BIS O score O for O any O recalled O word O was O 91 O . O 5 O ( O + O / O - O 11 O . O 1 O ; O range O 79 O to O 98 O ) O , O and O no O words O were O recalled O when O the O corresponding O BIS O score O was O less O than O 90 O . O CONCLUSIONS O : O There O is O a O range O of O BIS O scores O during O which O sedated O patients O are O able O to O repeat O words O read O to O them O but O are O not O able O to O subsequently O recall O these O words O . O Furthermore O , O patients O had O no O recall O of O words O repeated O prior O to O procedural O sedation O in O BIS O ranges O associated O with O recall O after O procedural O sedation O , O suggestive O of O retrograde B-Disease amnesia I-Disease . O Amiodarone B-Chemical pulmonary B-Disease toxicity I-Disease . O Amiodarone B-Chemical is O an O effective O antiarrhythmic O agent O whose O utility O is O limited O by O many O side O - O effects O , O the O most O problematic O being O pneumonitis B-Disease . O The O pulmonary B-Disease toxicity I-Disease of O amiodarone B-Chemical is O thought O to O result O from O direct O injury O related O to O the O intracellular O accumulation O of O phospholipid O and O T O cell O - O mediated O hypersensitivity B-Disease pneumonitis I-Disease . O The O clinical O and O radiographic O features O of O amiodarone B-Chemical - O induced O pulmonary B-Disease toxicity I-Disease are O characteristic O but O nonspecific O . O The O diagnosis O depends O on O exclusion O of O other O entities O , O such O as O heart B-Disease failure I-Disease , O infection B-Disease , O and O malignancy B-Disease . O While O withdrawal O of O amiodarone B-Chemical leads O to O clinical O improvement O in O majority O of O cases O , O this O is O not O always O possible O or O advisable O . O Dose O reduction O or O concomitant O steroid B-Chemical therapy O may O have O a O role O in O selected O patients O . O Two O prodrugs O of O potent O and O selective O GluR5 O kainate B-Chemical receptor O antagonists O actives O in O three O animal O models O of O pain B-Disease . O Amino O acids O 5 O and O 7 O , O two O potent O and O selective O competitive O GluR5 O KA B-Chemical receptor O antagonists O , O exhibited O high O GluR5 O receptor O affinity O over O other O glutamate B-Chemical receptors O . O Their O ester O prodrugs O 6 O and O 8 O were O orally O active O in O three O models O of O pain B-Disease : O reversal O of O formalin B-Chemical - O induced O paw O licking O , O carrageenan B-Chemical - O induced O thermal B-Disease hyperalgesia I-Disease , O and O capsaicin B-Chemical - O induced O mechanical B-Disease hyperalgesia I-Disease . O Possible O azithromycin B-Chemical - O associated O hiccups B-Disease . O OBJECTIVE O : O To O report O a O case O of O persistent O hiccups B-Disease associated O by O azithromycin B-Chemical therapy O . O CASE O SUMMARY O : O A O 76 O - O year O - O old O man O presented O with O persistent O hiccups B-Disease after O beginning O azithromycin B-Chemical for O the O treatment O of O pharyngitis B-Disease . O Hiccups B-Disease were O persistent O and O exhausting O . O Discontinuation O of O azithromycin B-Chemical and O therapy O with O baclofen B-Chemical finally O resolved O hiccups B-Disease . O No O organic O cause O of O hiccups B-Disease was O identified O despite O extensive O investigation O . O DISCUSSION O : O Pharmacotherapeutic O agents O have O been O uncommonly O associated O with O hiccups B-Disease . O Corticosteroids O ( O dexamethasone B-Chemical and O methylprednisolone B-Chemical ) O , O benzodiazepines B-Chemical ( O midazolam B-Chemical ) O and O general O anaesthesia O have O been O the O specific O agents O mentioned O most O frequently O in O the O literature O as O being O associated O with O the O development O of O hiccups B-Disease . O Few O cases O of O drug O - O induced O hiccups B-Disease have O been O reported O related O to O macrolide B-Chemical antimicrobials O . O Using O the O Naranjo O adverse O effect O reaction O probability O scale O this O event O could O be O classified O as O possible O ( O score O 5 O points O ) O , O mostly O because O of O the O close O temporal O sequence O , O previous O reports O on O this O reaction O with O other O macrolides B-Chemical and O the O absence O of O any O alternative O explanation O for O hiccups B-Disease . O Our O hypothesis O is O that O a O vagal O mechanism O mediated O by O azithromycin B-Chemical could O be O the O pathogenesis O of O hiccups B-Disease in O our O patient O . O CONCLUSIONS O : O Diagnosis O of O drug O - O induced O hiccups B-Disease is O difficult O and O often O achieved O only O by O a O process O of O elimination O . O However O , O macrolide B-Chemical antimicrobials O have O been O reported O to O be O associated O with O hiccups B-Disease and O vagal O mechanism O could O explain O the O development O of O this O side O - O effect O . O Calcium B-Chemical carbonate I-Chemical toxicity B-Disease : O the O updated O milk B-Disease - I-Disease alkali I-Disease syndrome I-Disease ; O report O of O 3 O cases O and O review O of O the O literature O .

O METHODS O : O We O report O the O clinical O and O laboratory O data O in O 3 O patients O who O presented O with O severe O hypercalcemia B-Disease ( O corrected O serum O calcium B-Chemical > O or O = O 14 O mg O / O dL O ) O and O review O the O pertinent O literature O on O milk B-Disease - I-Disease alkali I-Disease syndrome I-Disease . O RESULTS O : O The O 3 O patients O had O acute B-Disease renal I-Disease insufficiency I-Disease , O relative O metabolic B-Disease alkalosis I-Disease , O and O low O parathyroid O hormone O ( O PTH O ) O , O PTH O - O related O peptide O , O and O 1 B-Chemical , I-Chemical 25 I-Chemical - I-Chemical dihydroxyvitamin I-Chemical D I-Chemical concentrations O . O No O malignant O lesion O was O found O . O Treatment O included O aggressive O hydration O and O varied O amounts O of O furosemide B-Chemical . O The O 2 O patients O with O the O higher O serum O calcium B-Chemical concentrations O received O pamidronate B-Chemical intravenously O ( O 60 O and O 30 O mg O , O respectively O ) O , O which O caused O severe O hypocalcemia B-Disease . O Of O the O 3 O patients O , O 2 O were O ingesting O acceptable O doses O of O elemental O calcium B-Chemical ( O 1 O g O and O 2 O g O daily O , O respectively O ) O in O the O form O of O calcium B-Chemical carbonate I-Chemical . O In O addition O to O our O highlighted O cases O , O we O review O the O history O , O classification O , O pathophysiologic O features O , O and O treatment O of O milk B-Disease - I-Disease alkali I-Disease syndrome I-Disease and O summarize O the O cases O reported O from O early O 1995 O to O November O 2003 O . O CONCLUSION O : O Milk B-Disease - I-Disease alkali I-Disease syndrome I-Disease may O be O a O common O cause O of O unexplained O hypercalcemia B-Disease and O can O be O precipitated O by O small O amounts O of O orally O ingested O calcium B-Chemical carbonate I-Chemical in O susceptible O persons O . O Treatment O with O hydration O , O furosemide B-Chemical , O and O discontinuation O of O the O calcium B-Chemical and O vitamin B-Chemical D I-Chemical source O is O adequate O . O Pamidronate B-Chemical treatment O is O associated O with O considerable O risk O for O hypocalcemia B-Disease , O even O in O cases O of O initially O severe O hypercalcemia B-Disease . O Warfarin B-Chemical - O induced O leukocytoclastic B-Disease vasculitis I-Disease .

O METHODS O : O We O screened O patients O with O SAH B-Disease retrospectively O and O identified O those O with O positive O urine O toxicology O for O cocaine B-Chemical or O its O metabolites O . O Quantitative O arterial O diameter O measurements O from O angiograms O of O these O patients O were O compared O to O measurements O from O control O patients O with O SAH B-Disease who O were O matched O for O factors O known O to O influence O arterial O diameter O . O Qualitative O comparisons O of O small O artery O changes O also O were O made O . O RESULTS O : O Thirteen O patients O with O positive O cocaine B-Chemical toxicology O were O compared O to O 26 O controls O . O There O were O no O significant O differences O between O groups O in O the O mean O diameters O of O the O intradural O internal O carotid O , O sphenoidal O segment O of O the O middle O cerebral O , O precommunicating O segment O of O the O anterior O cerebral O , O or O basilar O arteries O ( O p O greater O than O 0 O .

O CONCLUSION O : O No O quantitative O evidence O for O narrowing O of O large O cerebral O arteries O or O qualitative O angiographic O evidence O for O distal O narrowing O or O vasculitis B-Disease could O be O found O in O patients O who O underwent O angiography O after O aneurysmal B-Disease SAH B-Disease associated O with O cocaine B-Chemical use O . O Methamphetamine B-Chemical causes O alterations O in O the O MAP O kinase O - O related O pathways O in O the O brains O of O mice O that O display O increased O aggressiveness B-Disease . O Aggressive B-Disease behaviors I-Disease have O been O reported O in O patients O who O suffer O from O some O psychiatric B-Disease disorders I-Disease , O and O are O common O in O methamphetamine B-Chemical ( O METH B-Chemical ) O abusers O . O Herein O , O we O report O that O multiple O ( O but O not O single O ) O injections O of O METH B-Chemical significantly O increased O aggressiveness B-Disease in O male O CD O - O 1 O mice O . O This O increase O in O aggressiveness B-Disease was O not O secondary O to O METH B-Chemical - O induced O hyperactivity B-Disease . O Analysis O of O protein O expression O using O antibody O microarrays O and O Western O blotting O revealed O differential O changes O in O MAP O kinase O - O related O pathways O after O multiple O and O single O METH B-Chemical injections O . O There O were O statistically O significant O ( O p O < O 0 O .

O MEK1 O was O significantly O decreased O also O after O a O single O injection O of O METH B-Chemical , O but O to O a O much O lesser O degree O than O after O multiple O injections O of O METH B-Chemical . O In O the O frontal O cortex O , O there O was O a O statistically O significant O decrease O in O GSK3alpha O after O multiple O ( O but O not O single O ) O injections O of O METH B-Chemical . O These O findings O suggest O that O alterations O in O MAP O kinase O - O related O pathways O in O the O prefronto O - O striatal O circuitries O might O be O involved O in O the O manifestation O of O aggressive B-Disease behaviors I-Disease in O mice O . O Amisulpride B-Chemical related O tic B-Disease - I-Disease like I-Disease symptoms I-Disease in O an O adolescent O schizophrenic B-Disease . O Tic B-Disease disorders I-Disease can O be O effectively O treated O by O atypical O antipsychotics O such O as O risperidone B-Chemical , O olanzapine B-Chemical and O ziprasidone B-Chemical . O However O , O there O are O two O case O reports O that O show O tic B-Disease - I-Disease like I-Disease symptoms I-Disease , O including O motor O and O phonic O variants O , O occurring O during O treatment O with O quetiapine B-Chemical or O clozapine B-Chemical . O We O present O a O 15 O - O year O - O old O girl O schizophrenic B-Disease who O developed O frequent O involuntary B-Disease eye I-Disease - I-Disease blinking I-Disease movements I-Disease after O 5 O months O of O amisulpride B-Chemical treatment O ( O 1000 O mg O per O day O ) O . O The O tic B-Disease - I-Disease like I-Disease symptoms I-Disease resolved O completely O after O we O reduced O the O dose O of O amisulpride B-Chemical down O to O 800 O mg O per O day O . O However O , O her O psychosis B-Disease recurred O after O the O dose O reduction O . O We O then O placed O her O on O an O additional O 100 O mg O per O day O of O quetiapine B-Chemical .

O Role O of O mangiferin B-Chemical on O biochemical O alterations O and O antioxidant O status O in O isoproterenol B-Chemical - O induced O myocardial B-Disease infarction I-Disease in O rats O . O The O current O study O dealt O with O the O protective O role O of O mangiferin B-Chemical , O a O polyphenol B-Chemical from O Mangifera O indica O Linn O . O ( O Anacardiaceae O ) O , O on O isoproterenol B-Chemical ( O ISPH B-Chemical ) O - O induced O myocardial B-Disease infarction I-Disease ( O MI B-Disease ) O in O rats O through O its O antioxidative O mechanism O . O Subcutaneous O injection O of O ISPH B-Chemical ( O 200 O mg O / O kg O body O weight O in O 1 O ml O saline O ) O to O rats O for O 2 O consecutive O days O caused O myocardial B-Disease damage I-Disease in O rat O heart O , O which O was O determined O by O the O increased O activity O of O serum O lactate B-Chemical dehydrogenase O ( O LDH O ) O and O creatine B-Chemical phosphokinase O isoenzymes O ( O CK O - O MB O ) O , O increased O uric B-Chemical acid I-Chemical level O and O reduced O plasma O iron B-Chemical binding O capacity O . O The O protective O role O of O mangiferin B-Chemical was O analyzed O by O triphenyl B-Chemical tetrazolium I-Chemical chloride I-Chemical ( O TTC B-Chemical ) O test O used O for O macroscopic O enzyme O mapping O assay O of O the O ischemic B-Disease myocardium I-Disease . O The O heart O tissue O antioxidant O enzymes O such O as O superoxide B-Chemical dismutase O , O catalase O , O glutathione B-Chemical peroxidase O , O glutathione B-Chemical transferase O and O glutathione B-Chemical reductase O activities O , O non O - O enzymic O antioxidants O such O as O cerruloplasmin O , O Vitamin B-Chemical C I-Chemical , O Vitamin B-Chemical E I-Chemical and O glutathione B-Chemical levels O were O altered O in O MI B-Disease rats O . O Upon O pretreatment O with O mangiferin B-Chemical ( O 100 O mg O / O kg O body O weight O suspended O in O 2 O ml O of O dimethyl B-Chemical sulphoxide I-Chemical ) O given O intraperitoneally O for O 28 O days O to O MI B-Disease rats O protected O the O above O - O mentioned O parameters O to O fall O from O the O normal O levels O . O Activities O of O heart O tissue O enzymic O antioxidants O and O serum O non O - O enzymic O antioxidants O levels O rose O significantly O upon O mangiferin B-Chemical administration O as O compared O to O ISPH B-Chemical - O induced O MI B-Disease rats O . O From O the O present O study O it O is O concluded O that O mangiferin B-Chemical exerts O a O beneficial O effect O against O ISPH B-Chemical - O induced O MI B-Disease due O to O its O antioxidant O potential O , O which O regulated O the O tissues O defense O system O against O cardiac B-Disease damage I-Disease . O Cardiovascular O risk O with O cyclooxygenase B-Chemical inhibitors I-Chemical : O general O problem O with O substance O specific O differences O ? O Randomised O clinical O trials O and O observational O studies O have O shown O an O increased O risk O of O myocardial B-Disease infarction I-Disease , O stroke B-Disease , O hypertension B-Disease and O heart B-Disease failure I-Disease during O treatment O with O cyclooxygenase B-Chemical inhibitors I-Chemical . O Adverse O cardiovascular O effects O occurred O mainly O , O but O not O exclusively O , O in O patients O with O concomitant O risk O factors O . O Cyclooxygenase B-Chemical inhibitors I-Chemical cause O complex O changes O in O renal O , O vascular O and O cardiac O prostanoid O profiles O thereby O increasing O vascular O resistance O and O fluid O retention O . O The O incidence O of O cardiovascular O adverse O events O tends O to O increase O with O the O daily O dose O and O total O exposure O time O . O A O comparison O of O individual O selective O and O unselective O cyclooxygenase B-Chemical inhibitors I-Chemical suggests O substance O - O specific O differences O , O which O may O depend O on O differences O in O pharmacokinetic O parameters O or O inhibitory O potency O and O may O be O contributed O by O prostaglandin B-Chemical - O independent O effects O . O Diagnostic O markers O such O as O N B-Chemical - I-Chemical terminal I-Chemical pro I-Chemical brain I-Chemical natriuretic I-Chemical peptide I-Chemical ( O NT B-Chemical - I-Chemical proBNP I-Chemical ) O or O high O - O sensitive O C O - O reactive O protein O might O help O in O the O early O identification O of O patients O at O risk O , O thus O avoiding O the O occurrence O of O serious O cardiovascular B-Disease toxicity I-Disease . O Pilocarpine B-Chemical seizures B-Disease cause O age O - O dependent O impairment B-Disease in I-Disease auditory I-Disease location I-Disease discrimination I-Disease . O Children O who O have O status B-Disease epilepticus I-Disease have O continuous O or O rapidly O repeating O seizures B-Disease that O may O be O life O - O threatening O and O may O cause O life O - O long O changes O in O brain O and O behavior O . O The O extent O to O which O status B-Disease epilepticus I-Disease causes O deficits B-Disease in I-Disease auditory I-Disease discrimination I-Disease is O unknown O . O A O naturalistic O auditory O location O discrimination O method O was O used O to O evaluate O this O question O using O an O animal O model O of O status B-Disease epilepticus I-Disease . O Male O Sprague O - O Dawley O rats O were O injected O with O saline O on O postnatal O day O ( O P O ) O 20 O , O or O a O convulsant O dose O of O pilocarpine B-Chemical on O P20 O or O P45 O . O Pilocarpine B-Chemical on O either O day O induced O status B-Disease epilepticus I-Disease ; O status B-Disease epilepticus I-Disease at O P45 O resulted O in O CA3 O cell O loss O and O spontaneous O seizures B-Disease , O whereas O P20 O rats O had O no O cell O loss O or O spontaneous O seizures B-Disease . O Mature O rats O were O trained O with O sound O - O source O location O and O sound O - O silence O discriminations O . O Control O ( O saline O P20 O ) O rats O acquired O both O discriminations O immediately O . O In O status B-Disease epilepticus I-Disease ( O P20 O ) O rats O , O acquisition O of O the O sound O - O source O location O discrimination O was O moderately O impaired O . O Status B-Disease epilepticus I-Disease ( O P45 O ) O rats O failed O to O acquire O either O sound O - O source O location O or O sound O - O silence O discriminations O . O Status B-Disease epilepticus I-Disease in O rat O causes O an O age O - O dependent O , O long O - O term O impairment B-Disease in I-Disease auditory I-Disease discrimination I-Disease . O This O impairment O may O explain O one O cause O of O impaired B-Disease auditory I-Disease location I-Disease discrimination I-Disease in O humans O . O Nerve O growth O factor O and O prostaglandins B-Chemical in O the O urine O of O female O patients O with O overactive B-Disease bladder I-Disease . O PURPOSE O : O NGF O and O PGs B-Chemical in O the O bladder O can O be O affected O by O pathological O changes O in O the O bladder O and O these O changes O can O be O detected O in O urine O . O We O investigated O changes O in O urinary O NGF O and O PGs B-Chemical in O women O with O OAB B-Disease . O MATERIALS O AND O METHODS O : O The O study O groups O included O 65 O women O with O OAB B-Disease and O 20 O without O bladder O symptoms O who O served O as O controls O . O Evaluation O included O patient O history O , O urinalysis O , O a O voiding O diary O and O urodynamic O studies O . O Urine O samples O were O collected O . O NGF O , O PGE2 B-Chemical , O PGF2alpha B-Chemical and O PGI2 B-Chemical were O measured O using O enzyme O - O linked O immunosorbent O assay O and O compared O between O the O groups O . O In O addition O , O correlations O between O urinary O NGF O and O PG B-Chemical , O and O urodynamic O parameters O in O patients O with O OAB B-Disease were O examined O . O RESULTS O : O Urinary O NGF O , O PGE2 B-Chemical and O PGF2alpha B-Chemical were O significantly O increased O in O patients O with O OAB B-Disease compared O with O controls O ( O p O < O 0 O . O 05 O ) O . O However O , O urinary O PGI2 B-Chemical was O not O different O between O controls O and O patients O with O OAB B-Disease . O In O patients O with O OAB B-Disease urinary O PGE2 B-Chemical positively O correlated O with O volume O at O first O desire O to O void O and O maximum O cystometric O capacity O ( O p O < O 0 O . O 05 O ) O . O Urinary O NGF O , O PGF2alpha B-Chemical and O PGI2 B-Chemical did O not O correlate O with O urodynamic O parameters O in O patients O with O OAB B-Disease . O CONCLUSIONS O : O NGF O and O PGs B-Chemical have O important O roles O in O the O development O of O OAB B-Disease symptoms O in O female O patients O . O Urinary O levels O of O these O factors O may O be O used O as O markers O to O evaluate O OAB B-Disease symptoms O . O Definition O and O management O of O anemia B-Disease in O patients O infected B-Disease with I-Disease hepatitis I-Disease C I-Disease virus I-Disease . O Chronic B-Disease infection I-Disease with I-Disease hepatitis I-Disease C I-Disease virus I-Disease ( O HCV O ) O can O progress O to O cirrhosis B-Disease , O hepatocellular B-Disease carcinoma I-Disease , O and O end B-Disease - I-Disease stage I-Disease liver I-Disease disease I-Disease . O The O current O best O treatment O for O HCV B-Disease infection I-Disease is O combination O therapy O with O pegylated O interferon B-Chemical and O ribavirin B-Chemical . O Although O this O regimen O produces O sustained O virologic O responses O ( O SVRs O ) O in O approximately O 50 O % O of O patients O , O it O can O be O associated O with O a O potentially O dose O - O limiting O hemolytic B-Disease anemia I-Disease . O Hemoglobin O concentrations O decrease O mainly O as O a O result O of O ribavirin B-Chemical - O induced O hemolysis B-Disease , O and O this O anemia B-Disease can O be O problematic O in O patients O with O HCV B-Disease infection I-Disease , O especially O those O who O have O comorbid O renal B-Disease or I-Disease cardiovascular I-Disease disorders I-Disease . O In O general O , O anemia B-Disease can O increase O the O risk O of O morbidity O and O mortality O , O and O may O have O negative O effects O on O cerebral O function O and O quality O of O life O . O Although O ribavirin B-Chemical - O associated O anemia B-Disease can O be O reversed O by O dose O reduction O or O discontinuation O , O this O approach O compromises O outcomes O by O significantly O decreasing O SVR O rates O . O Recombinant O human O erythropoietin O has O been O used O to O manage O ribavirin B-Chemical - O associated O anemia B-Disease but O has O other O potential O disadvantages O . O Viramidine B-Chemical , O a O liver O - O targeting O prodrug O of O ribavirin B-Chemical , O has O the O potential O to O maintain O the O virologic O efficacy O of O ribavirin B-Chemical while O decreasing O the O risk O of O hemolytic B-Disease anemia I-Disease in O patients O with O chronic B-Disease hepatitis I-Disease C I-Disease . O Impact O of O alcohol B-Chemical exposure O after O pregnancy O recognition O on O ultrasonographic O fetal O growth O measures O . O BACKGROUND O : O More O than O 3 O decades O after O Jones O and O Smith O ( O 1973 O ) O reported O on O the O devastation O caused O by O alcohol B-Chemical exposure O on O fetal O development O , O the O rates O of O heavy O drinking O during O pregnancy O remain O relatively O unchanged O . O Early O identification O of O fetal O alcohol B-Chemical exposure O and O maternal O abstinence O led O to O better O infant O outcomes O . O This O study O examined O the O utility O of O biometry O for O detecting O alcohol B-Chemical - O related O fetal O growth B-Disease impairment I-Disease . O METHODS O : O We O obtained O fetal O ultrasound O measures O from O routine O ultrasound O examinations O for O 167 O pregnant O hazardous O drinkers O who O were O enrolled O in O a O brief O alcohol B-Chemical intervention O study O . O The O fetal O measures O for O women O who O quit O after O learning O of O their O pregnancies O were O compared O with O measures O for O women O who O continued O some O drinking O throughout O the O course O of O their O pregnancies O . O Because O intensity O of O alcohol B-Chemical consumption O is O associated O with O poorer O fetal O outcomes O , O separate O analyses O were O conducted O for O the O heavy O ( O average O of O > O or O = O 5 O drinks O per O drinking O day O ) O alcohol B-Chemical consumers O . O Fetal O measures O from O the O heavy O - O exposed O fetuses O were O also O compared O with O measures O from O a O nondrinking O group O that O was O representative O of O normal O , O uncomplicated O pregnancies O from O our O clinics O . O Analyses O of O covariance O were O used O to O determine O whether O there O were O differences O between O groups O after O controlling O for O influences O of O gestational O age O and O drug B-Disease abuse I-Disease . O RESULTS O : O Nearly O half O of O the O pregnant O drinkers O abstained O after O learning O of O their O pregnancies O . O When O women O reportedly O quit O drinking O early O in O their O pregnancies O , O fetal O growth O measures O were O not O significantly O different O from O a O non O - O alcohol B-Chemical - O exposed O group O , O regardless O of O prior O drinking O patterns O . O Any O alcohol B-Chemical consumption O postpregnancy O recognition O among O the O heavy O drinkers O resulted O in O reduced B-Disease cerebellar I-Disease growth I-Disease as O well O as O decreased B-Disease cranial I-Disease to I-Disease body I-Disease growth I-Disease in O comparison O with O women O who O either O quit O drinking O or O who O were O nondrinkers O . O Amphetamine B-Chemical abuse O was O predictive O of O larger O cranial O to O body O growth O ratios O . O CONCLUSIONS O : O Alterations O in O fetal O biometric O measurements O were O observed O among O the O heavy O drinkers O only O when O they O continued O drinking O after O becoming O aware O of O their O pregnancies O . O Although O the O reliance O on O self O - O reported O drinking O is O a O limitation O in O this O study O , O these O findings O support O the O benefits O of O early O abstinence O and O the O potential O for O ultrasound O examinations O in O the O detection O of O fetal O alcohol B-Chemical effects O . O Ethambutol B-Chemical - O associated O optic B-Disease neuropathy I-Disease . O INTRODUCTION O : O Ethambutol B-Chemical is O used O in O the O treatment O of O tuberculosis B-Disease , O which O is O still O prevalent O in O Southeast O Asia O , O and O can O be O associated O with O permanent O visual B-Disease loss I-Disease . O We O report O 3 O cases O which O presented O with O bitemporal B-Disease hemianopia I-Disease . O CLINICAL O PICTURE O : O Three O patients O with O ethambutol B-Chemical - O associated O toxic O optic B-Disease neuropathy I-Disease are O described O . O All O 3 O patients O had O loss B-Disease of I-Disease central I-Disease visual I-Disease acuity I-Disease , I-Disease colour I-Disease vision I-Disease ( I-Disease Ishihara I-Disease ) I-Disease and I-Disease visual I-Disease field I-Disease . O The O visual B-Disease field I-Disease loss I-Disease had O a O bitemporal O flavour O , O suggesting O involvement O of O the O optic O chiasm O . O TREATMENT O : O Despite O stopping O ethambutol B-Chemical on O diagnosis O , O visual O function O continued O to O deteriorate O for O a O few O months O . O Subsequent O improvement O was O mild O in O 2 O cases O . O In O the O third O case O , O visual O acuity O and O colour O vision O normalised O but O the O optic O discs O were O pale O . O OUTCOME O : O All O 3 O patients O had O some O permanent O loss B-Disease of I-Disease visual I-Disease function I-Disease . O CONCLUSIONS O : O Ethambutol B-Chemical usage O is O associated O with O permanent O visual B-Disease loss I-Disease and O should O be O avoided O if O possible O or O used O with O caution O and O proper O ophthalmological O follow O - O up O . O The O author O postulates O that O in O cases O of O ethambutol B-Chemical associated O chiasmopathy O , O ethambutol B-Chemical may O initially O affect O the O optic O nerves O and O subsequently O progress O to O involve O the O optic O chiasm O . O Possible O neuroleptic B-Disease malignant I-Disease syndrome I-Disease related O to O concomitant O treatment O with O paroxetine B-Chemical and O alprazolam B-Chemical . O A O 74 O - O year O - O old O man O with O depressive B-Disease symptoms I-Disease was O admitted O to O a O psychiatric B-Disease hospital O due O to O insomnia B-Disease , O loss B-Disease of I-Disease appetite I-Disease , O exhaustion O , O and O agitation B-Disease . O Medical O treatment O was O initiated O at O a O daily O dose O of O 20 O mg O paroxetine B-Chemical and O 1 O . O 2 O mg O alprazolam B-Chemical . O On O the O 10th O day O of O paroxetine B-Chemical and O alprazolam B-Chemical treatment O , O the O patient O exhibited O marked O psychomotor B-Disease retardation I-Disease , O disorientation O , O and O severe O muscle B-Disease rigidity I-Disease with O tremors B-Disease . O The O patient O had O a O fever B-Disease ( O 38 O . O 2 O degrees O C O ) O , O fluctuating O blood O pressure O ( O between O 165 O / O 90 O and O 130 O / O 70 O mg O mm O Hg O ) O , O and O severe O extrapyramidal B-Disease symptoms I-Disease . O Laboratory O tests O showed O an O elevation O of O creatine B-Chemical phosphokinase O ( O 2218 O IU O / O L O ) O , O aspartate B-Chemical aminotransferase O ( O 134 O IU O / O L O ) O , O alanine B-Chemical aminotransferase O ( O 78 O IU O / O L O ) O , O and O BUN O ( O 27 O . O 9 O mg O / O ml O ) O levels O . O The O patient O received O bromocriptine B-Chemical and O diazepam B-Chemical to O treat O his O symptoms O . O 7 O days O later O , O the O fever B-Disease disappeared O and O the O patient O ' O s O serum O CPK O levels O were O normalized O ( O 175 O IU O / O L O ) O . O This O patient O presented O with O symptoms O of O neuroleptic B-Disease malignant I-Disease syndrome I-Disease ( O NMS B-Disease ) O , O thus O demonstrating O that O NMS B-Disease - O like O symptoms O can O occur O after O combined O paroxetine B-Chemical and O alprazolam B-Chemical treatment O . O The O adverse O drug O reaction O score O obtained O by O the O Naranjo O algorithm O was O 6 O in O our O case O , O indicating O a O probable O relationship O between O the O patient O ' O s O NMS B-Disease - O like O adverse O symptoms O and O the O combined O treatment O used O in O this O case O . O The O involvement O of O physiologic O and O environmental O aspects O specific O to O this O patient O was O suspected O . O Several O risk O factors O for O NMS B-Disease should O be O noted O in O elderly O depressive B-Disease patients O whose O symptoms O often O include O dehydration B-Disease , O agitation B-Disease , O malnutrition B-Disease , O and O exhaustion O . O Careful O therapeutic O intervention O is O necessary O in O cases O involving O elderly O patients O who O suffer O from O depression B-Disease . O Down O - O regulation O of O norepinephrine B-Chemical transporter O function O induced O by O chronic O administration O of O desipramine B-Chemical linking O to O the O alteration O of O sensitivity O of O local O - O anesthetics O - O induced O convulsions B-Disease and O the O counteraction O by O co O - O administration O with O local O anesthetics O . O Alterations O of O norepinephrine B-Chemical transporter O ( O NET O ) O function O by O chronic O inhibition O of O NET O in O relation O to O sensitization O to O seizures B-Disease induce O by O cocaine B-Chemical and O local O anesthetics O were O studied O in O mice O . O Daily O administration O of O desipramine B-Chemical , O an O inhibitor O of O the O NET O , O for O 5 O days O decreased O [ O ( O 3 O ) O H O ] O norepinephrine B-Chemical uptake O in O the O P2 O fractions O of O hippocampus O but O not O cortex O , O striatum O or O amygdalae O . O Co O - O administration O of O lidocaine B-Chemical , O bupivacaine B-Chemical or O tricaine B-Chemical with O desipramine B-Chemical reversed O this O effect O . O Daily O treatment O of O cocaine B-Chemical increased O [ O ( O 3 O ) O H O ] O norepinephrine B-Chemical uptake O into O the O hippocampus O . O Daily O administration O of O desipramine B-Chemical increased O the O incidence O of O appearance O of O lidocaine B-Chemical - O induced O convulsions B-Disease and O decreased O that O of O cocaine B-Chemical - O induced O convulsions B-Disease . O Co O - O administration O of O lidocaine B-Chemical with O desipramine B-Chemical reversed O the O changes O of O convulsive B-Disease activity O of O lidocaine B-Chemical and O cocaine B-Chemical induced O by O repeated O administration O of O desipramine B-Chemical . O These O results O suggest O that O down O - O regulation O of O hippocampal O NET O induced O by O chronic O administration O of O desipramine B-Chemical may O be O relevant O to O desipramine B-Chemical - O induced O sensitization O of O lidocaine B-Chemical convulsions B-Disease . O Inhibition O of O Na B-Chemical ( O + O ) O channels O by O local O anesthetics O may O regulate O desipramine B-Chemical - O induced O down O - O regulation O of O NET O function O . O Repeated O administration O of O cocaine B-Chemical induces O up O - O regulation O of O hippocampal O NET O function O . O Desipramine B-Chemical - O induced O sensitization O of O lidocaine B-Chemical seizures B-Disease may O have O a O mechanism O distinct O from O kindling O resulting O from O repeated O administration O of O cocaine B-Chemical . O Atorvastatin B-Chemical prevented O and O reversed O dexamethasone B-Chemical - O induced O hypertension B-Disease in O the O rat O . O To O assess O the O antioxidant O effects O of O atorvastatin B-Chemical ( O atorva B-Chemical ) O on O dexamethasone B-Chemical ( O dex B-Chemical ) O - O induced O hypertension B-Disease , O 60 O male O Sprague O - O Dawley O rats O were O treated O with O atorva B-Chemical 30 O mg O / O kg O / O day O or O tap O water O for O 15 O days O . O Dex B-Chemical increased O systolic O blood O pressure O ( O SBP O ) O from O 109 O + O / O - O 1 O . O 8 O to O 135 O + O / O - O 0 O . O 6 O mmHg O and O plasma O superoxide B-Chemical ( O 5711 O + O / O - O 284 O . O 9 O saline O , O 7931 O + O / O - O 392 O . O 8 O U O / O ml O dex B-Chemical , O P O < O 0 O . O 001 O ) O . O In O this O prevention O study O , O SBP O in O the O atorva B-Chemical + O dex B-Chemical group O was O increased O from O 115 O + O / O - O 0 O . O 4 O to O 124 O + O / O - O 1 O . O 5 O mmHg O , O but O this O was O significantly O lower O than O in O the O dex B-Chemical - O only O group O ( O P O ' O < O 0 O . O 05 O ) O . O Atorva B-Chemical reversed O dex B-Chemical - O induced O hypertension B-Disease ( O 129 O + O / O - O 0 O . O 6 O mmHg O , O vs O . O 135 O + O / O - O 0 O . O 6 O mmHg O P O ' O < O 0 O .

O Atorva B-Chemical affected O neither O plasma O NOx O nor O thymus O weight O . O Thus O , O atorvastatin B-Chemical prevented O and O reversed O dexamethasone B-Chemical - O induced O hypertension B-Disease in O the O rat O . O Peripheral B-Disease neuropathy I-Disease caused O by O high O - O dose O cytosine B-Chemical arabinoside I-Chemical treatment O in O a O patient O with O acute B-Disease myeloid I-Disease leukemia I-Disease . O The O central O nervous O system O toxicity B-Disease of O high O - O dose O cytosine B-Chemical arabinoside I-Chemical is O well O recognized O , O but O the O toxicity B-Disease of O cytosine B-Chemical arabinoside I-Chemical in O the O peripheral O nervous O system O has O been O infrequently O reported O . O A O 49 O - O year O - O old O Japanese O man O was O diagnosed O with O acute B-Disease myeloid I-Disease leukemia I-Disease . O After O he O achieved O complete O remission O , O he O received O high O - O dose O cytosine B-Chemical arabinoside I-Chemical treatment O ( O 2 O g O / O m2 O twice O a O day O for O 5 O days O ; O total O , O 20 O g O / O m2 O ) O as O consolidation O therapy O . O The O first O course O of O high O - O dose O cytosine B-Chemical arabinoside I-Chemical resulted O in O no O unusual O symptoms O , O but O on O day O 21 O of O the O second O course O of O treatment O , O the O patient O complained O of O numbness B-Disease in O his O right O foot O . O Electromyogram O and O nerve O - O conduction O studies O showed O peripheral B-Disease neuropathy I-Disease in O both O peroneal O nerves O . O This O neuropathy B-Disease was O gradually O resolving O ; O however O , O after O the O patient O received O allogeneic O bone O marrow O transplantation O , O the O symptoms O worsened O , O with O the O development O of O graft B-Disease - I-Disease versus I-Disease - I-Disease host I-Disease disease I-Disease , O and O the O symptoms O subsequently O responded O to O methylprednisolone B-Chemical . O Although O the O mechanisms O of O peripheral B-Disease neuropathy I-Disease are O still O unclear O , O high O - O dose O cytosine B-Chemical arabinoside I-Chemical is O a O therapy O that O is O potentially O toxic O to O the O peripheral O nervous O system O , O and O auto O / O alloimmunity O may O play O an O important O role O in O these O mechanisms O . O Effect O of O alpha B-Chemical - I-Chemical tocopherol I-Chemical and O deferoxamine B-Chemical on O methamphetamine B-Chemical - O induced O neurotoxicity B-Disease .

O She O was O discharged O from O the O ER O after O a O few O hours O of O treatment O with O fluid O and O analgesics O . O However O , O she O returned O to O the O ER O the O next O day O with O the O same O complaints O . O This O time O the O physical O exam O was O significant O for O a O distended O abdomen O with O dullness O to O percussion O . O CT O scan O of O the O abdomen O revealed O markedly O thickened O antrum O of O the O stomach O , O duodenum O and O jejunum O , O along O with O fluid O in O the O abdominal O and O pelvic O cavity O . O Angiotensin O - O converting O enzyme O inhibitor O ( O ACEI O ) O - O induced O angioedema B-Disease was O suspected O , O and O anti O - O hypertensive B-Disease medications O were O discontinued O . O Her O symptoms O improved O within O the O next O 24 O hours O , O and O repeat O CT O after O 72 O hours O revealed O marked O improvement O in O stomach O and O small O bowel O thickening O and O resolution O of O ascites B-Disease . O The O recognition O of O angiotensin B-Chemical - O converting O enzyme O ( O ACE O ) O and O angiotensin B-Chemical receptor O blocker O ( O ARB O ) O intestinal B-Disease angioedema I-Disease constitutes O a O challenge O to O primary O care O physicians O , O internists O , O emergency O room O personal O and O surgeons O . O Carbamazepine B-Chemical - O induced O cardiac B-Disease dysfunction I-Disease . O Characterization O of O two O distinct O clinical O syndromes O . O A O patient O with O sinus O bradycardia B-Disease and O atrioventricular B-Disease block I-Disease , O induced O by O carbamazepine B-Chemical , O prompted O an O extensive O literature O review O of O all O previously O reported O cases O . O From O the O analysis O of O these O cases O , O two O distinct O forms O of O carbamazepine B-Chemical - O associated O cardiac B-Disease dysfunction I-Disease emerged O . O One O patient O group O developed O sinus B-Disease tachycardias I-Disease in O the O setting O of O a O massive O carbamazepine B-Chemical overdose B-Disease . O The O second O group O consisted O almost O exclusively O of O elderly O women O who O developed O potentially O life O - O threatening O bradyarrhythmias B-Disease or O atrioventricular B-Disease conduction I-Disease delay I-Disease , O associated O with O either O therapeutic O or O modestly O elevated O carbamazepine B-Chemical serum O levels O . O Because O carbamazepine B-Chemical is O widely O used O in O the O treatment O of O many O neurologic O and O psychiatric B-Disease conditions O , O the O recognition O of O the O latter O syndrome O has O important O implications O for O the O use O of O this O drug O in O elderly O patients O . O Detection O of O abnormal O cardiac O adrenergic O neuron O activity O in O adriamycin B-Chemical - O induced O cardiomyopathy B-Disease with O iodine B-Chemical - I-Chemical 125 I-Chemical - I-Chemical metaiodobenzylguanidine I-Chemical . O Radiolabeled B-Chemical metaiodobenzylguanidine I-Chemical ( O MIBG B-Chemical ) O , O an O analog O of O norepinephrine B-Chemical ( O NE B-Chemical ) O , O serves O as O an O index O of O adrenergic O neuron O integrity O and O function O . O Using O a O rat O model O of O adriamycin B-Chemical - O induced O cardiomyopathy B-Disease , O we O tested O the O hypothesis O that O abnormal O cardiac O adrenergic O neuron O activity O may O appear O and O be O exacerbated O dose O - O dependently O in O adriamycin B-Chemical cardiomyopathy B-Disease . O The O degree O of O vacuolar B-Disease degeneration I-Disease of I-Disease myocardial I-Disease cells I-Disease was O analyzed O in O relation O to O the O duration O of O adriamycin B-Chemical treatment O ( O 2 O mg O / O kg O , O once O a O week O ) O . O There O were O no O abnormalities O or O only O isolated O degeneration O in O the O 1 O - O or O 2 O - O wk O treatment O groups O , O isolated O or O scattered O degeneration O in O half O of O the O 3 O - O wk O group O , O frequent O scattered O degeneration O in O the O 4 O - O wk O group O , O scattered O or O focal O degeneration O in O the O 5 O - O wk O group O , O and O extensive O degeneration O in O the O 8 O - O wk O group O . O Myocardial O accumulation O of O [ O 125I O ] O MIBG B-Chemical 4 O hr O after O intravenous O injection O did O not O differ O between O the O controls O and O the O groups O treated O 3 O wk O or O less O . O However O , O the O 4 O - O wk O group O had O a O slightly O lower O accumulation O in O the O right O ventricular O wall O ( O 82 O % O of O the O control O ) O and O significantly O lower O accumulation O in O the O left O ventricular O wall O ( O about O 66 O % O of O the O control O : O p O less O than O 0 O . O 05 O ) O . O In O the O 5 O - O wk O group O , O MIBG B-Chemical accumulation O in O the O right O and O left O ventricular O wall O was O 35 O % O and O 27 O % O of O that O in O controls O , O respectively O ( O p O less O than O 0 O . O 001 O ) O . O In O the O 8 O - O wk O group O , O MIBG B-Chemical accumulation O in O the O right O and O left O ventricular O wall O was O 18 O % O and O 14 O % O of O that O in O controls O , O respectively O ( O p O less O than O 0 O . O 001 O ) O . O Thus O , O MIBG B-Chemical accumulation O in O the O myocardium O decreased O in O an O adriamycin B-Chemical dose O - O dependent O manner O . O The O appearance O of O impaired O cardiac O adrenergic O neuron O activity O in O the O presence O of O slight O myocardial B-Disease impairment I-Disease ( O scattered O or O focal O vacuolar B-Disease degeneration I-Disease ) O indicates O that O MIBG B-Chemical scintigraphy O may O be O a O useful O method O for O detection O of O adriamycin B-Chemical - O induced O cardiomyopathy B-Disease . O Syncope B-Disease and O QT B-Disease prolongation I-Disease among O patients O treated O with O methadone B-Chemical for O heroin B-Chemical dependence O in O the O city O of O Copenhagen O . O BACKGROUND O : O Methadone B-Chemical is O prescribed O to O heroin B-Chemical addicts O to O decrease O illicit O opioid O use O . O Prolongation O of O the O QT O interval O in O the O ECG O of O patients O with O torsade B-Disease de I-Disease pointes I-Disease ( O TdP B-Disease ) O has O been O reported O in O methadone B-Chemical users O . O As O heroin B-Chemical addicts O sometimes O faint O while O using O illicit O drugs O , O doctors O might O attribute O too O many O episodes O of O syncope B-Disease to O illicit O drug O use O and O thereby O underestimate O the O incidence O of O TdP B-Disease in O this O special O population O , O and O the O high O mortality O in O this O population O may O , O in O part O , O be O caused O by O the O proarrhythmic O effect O of O methadone B-Chemical . O METHODS O : O In O this O cross O - O sectional O study O interview O , O ECGs O and O blood O samples O were O collected O in O a O population O of O adult O heroin B-Chemical addicts O treated O with O methadone B-Chemical or O buprenorphine B-Chemical on O a O daily O basis O . O Of O the O patients O at O the O Drug O Addiction O Service O in O the O municipal O of O Copenhagen O , O 450 O ( O approximately O 52 O % O ) O were O included O . O The O QT O interval O was O estimated O from O 12 O lead O ECGs O . O All O participants O were O interviewed O about O any O experience O of O syncope B-Disease . O The O association O between O opioid O dose O and O QT O , O and O methadone B-Chemical dose O and O reporting O of O syncope B-Disease was O assessed O using O multivariate O linear O regression O and O logistic O regression O , O respectively O . O RESULTS O : O Methadone B-Chemical dose O was O associated O with O longer O QT O interval O of O 0 O . O 140 O ms O / O mg O ( O p O = O 0 O . O 002 O ) O . O No O association O between O buprenorphine B-Chemical and O QTc O was O found O . O Among O the O subjects O treated O with O methadone B-Chemical , O 28 O % O men O and O 32 O % O women O had O prolonged B-Disease QTc I-Disease interval I-Disease . O None O of O the O subjects O treated O with O buprenorphine B-Chemical had O QTc O interval O > O 0 O . O 440 O s O ( O ( O 1 O / O 2 O ) O ) O . O A O 50 O mg O higher O methadone B-Chemical dose O was O associated O with O a O 1 O . O 2 O ( O 95 O % O CI O 1 O . O 1 O to O 1 O . O 4 O ) O times O higher O odds O for O syncope B-Disease . O CONCLUSIONS O : O Methadone B-Chemical is O associated O with O QT B-Disease prolongation I-Disease and O higher O reporting O of O syncope B-Disease in O a O population O of O heroin B-Chemical addicts O . O Neuroleptic B-Disease malignant I-Disease syndrome I-Disease induced O by O ziprasidone B-Chemical on O the O second O day O of O treatment O . O Neuroleptic B-Disease malignant I-Disease syndrome I-Disease ( O NMS B-Disease ) O is O the O rarest O and O most O serious O of O the O neuroleptic O - O induced O movement B-Disease disorders I-Disease . O We O describe O a O case O of O neuroleptic B-Disease malignant I-Disease syndrome I-Disease ( O NMS B-Disease ) O associated O with O the O use O of O ziprasidone B-Chemical . O Although O conventional O neuroleptics O are O more O frequently O associated O with O NMS B-Disease , O atypical O antipsychotic O drugs O like O ziprasidone B-Chemical may O also O be O a O cause O . O The O patient O is O a O 24 O - O year O - O old O male O with O a O history O of O schizophrenia B-Disease who O developed O signs O and O symptoms O of O NMS B-Disease after O 2 O days O of O treatment O with O an O 80 O - O mg O / O day O dose O of O orally O administrated O ziprasidone B-Chemical . O This O case O is O the O earliest O ( O second O day O of O treatment O ) O NMS B-Disease due O to O ziprasidone B-Chemical reported O in O the O literature O . O Peripheral O iron B-Chemical dextran I-Chemical induced O degeneration B-Disease of I-Disease dopaminergic I-Disease neurons I-Disease in O rat O substantia O nigra O . O Iron B-Chemical accumulation O is O considered O to O be O involved O in O the O pathogenesis O of O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease . O To O demonstrate O the O relationship O between O peripheral O iron B-Chemical overload O and O dopaminergic O neuron O loss O in O rat O substantia O nigra O ( O SN O ) O , O in O the O present O study O we O used O fast O cyclic O voltammetry O , O tyrosine B-Chemical hydroxylase O ( O TH O ) O immunohistochemistry O , O Perls O ' O iron B-Chemical staining O , O and O high O performance O liquid O chromatography O - O electrochemical O detection O to O study O the O degeneration B-Disease of I-Disease dopaminergic I-Disease neurons I-Disease and O increased O iron B-Chemical content O in O the O SN O of O iron B-Chemical dextran I-Chemical overloaded O animals O . O The O findings O showed O that O peripheral O iron B-Chemical dextran I-Chemical overload O increased O the O iron B-Chemical staining O positive O cells O and O reduced O the O number O of O TH O - O immunoreactive O neurons O in O the O SN O . O As O a O result O , O dopamine B-Chemical release O and O content O , O as O well O as O its O metabolites O contents O were O decreased O in O caudate O putamen O . O Even O more O dramatic O changes O were O found O in O chronic O overload O group O . O These O results O suggest O that O peripheral O iron B-Chemical dextran I-Chemical can O increase O the O iron B-Chemical level O in O the O SN O , O where O excessive O iron B-Chemical causes O the O degeneration B-Disease of I-Disease dopaminergic I-Disease neurons I-Disease . O The O chronic O iron B-Chemical overload O may O be O more O destructive O to O dopaminergic O neurons O than O the O acute O iron B-Chemical overload O . O Attenuated O disruption O of O prepulse O inhibition O by O dopaminergic O stimulation O after O maternal O deprivation O and O adolescent O corticosterone B-Chemical treatment O in O rats O . O The O development O of O schizophrenia B-Disease may O include O an O early O neurodevelopmental O stress O component O which O increases O vulnerability O to O later O stressful O life O events O , O in O combination O leading O to O overt O disease O . O We O investigated O the O effect O of O an O early O stress O , O in O the O form O of O maternal O deprivation O , O combined O with O a O later O stress O , O simulated O by O chronic O periadolescent O corticosterone B-Chemical treatment O , O on O behaviour O in O rats O . O Acute O treatment O with O apomorphine B-Chemical caused O disruption O of O prepulse O inhibition O ( O PPI O ) O in O controls O and O in O rats O that O had O undergone O either O maternal O deprivation O or O corticosterone B-Chemical treatment O , O but O was O surprisingly O absent O in O rats O that O had O undergone O the O combined O early O and O late O stress O . O Amphetamine B-Chemical treatment O significantly O disrupted O PPI O in O both O non O - O deprived O groups O , O but O was O absent O in O both O maternally O deprived O groups O . O The O serotonin B-Chemical - O 1A O receptor O agonist O , O 8 B-Chemical - I-Chemical OH I-Chemical - I-Chemical DPAT I-Chemical , O induced O a O significant O disruption O of O PPI O in O all O groups O . O Amphetamine B-Chemical - O induced O locomotor B-Disease hyperactivity I-Disease was O similar O in O all O groups O . O These O results O show O an O inhibitory O interaction O of O early O stress O , O caused O by O maternal O deprivation O , O combined O with O ' O adolescent O ' O stress O , O simulated O by O corticosterone B-Chemical treatment O , O on O dopaminergic O regulation O of O PPI O . O The O altered O effects O of O apomorphine B-Chemical and O amphetamine B-Chemical could O indicate O differential O changes O in O dopamine B-Chemical receptor O signalling O leading O to O functional O desensitisation O , O or O altered O modulation O of O sensory O gating O in O the O nucleus O accumbens O by O limbic O structures O such O as O the O hippocampus O . O An O extremely O rare O case O of O delusional B-Disease parasitosis I-Disease in O a O chronic B-Disease hepatitis I-Disease C I-Disease patient O during O pegylated B-Chemical interferon I-Chemical alpha I-Chemical - I-Chemical 2b I-Chemical and O ribavirin B-Chemical treatment O . O During O treatment O of O chronic B-Disease hepatitis I-Disease C I-Disease patients O with O interferon O and O ribavirin B-Chemical , O a O lot O of O side O effects O are O described O . O Twenty O - O three O percent O to O 44 O % O of O patients O develop O depression B-Disease . O A O minority O of O patients O evolve O to O psychosis B-Disease . O To O the O best O of O our O knowledge O , O no O cases O of O psychogenic B-Disease parasitosis I-Disease occurring O during O interferon O therapy O have O been O described O in O the O literature O . O We O present O a O 49 O - O year O - O old O woman O who O developed O a O delusional B-Disease parasitosis I-Disease during O treatment O with O pegylated B-Chemical interferon I-Chemical alpha I-Chemical - I-Chemical 2b I-Chemical weekly O and O ribavirin B-Chemical . O She O complained O of O seeing O parasites O and O the O larvae O of O fleas O in O her O stools O . O This O could O not O be O confirmed O by O any O technical O examination O . O All O the O complaints O disappeared O after O stopping O pegylated B-Chemical interferon I-Chemical alpha I-Chemical - I-Chemical 2b I-Chemical and O reappeared O after O restarting O it O . O She O had O a O complete O sustained O viral O response O . O Hepatonecrosis B-Disease and O cholangitis B-Disease related O to O long O - O term O phenobarbital B-Chemical therapy O : O an O autopsy O report O of O two O patients O . O Phenobarbital B-Chemical ( O PB B-Chemical ) O has O a O reputation O for O safety O , O and O it O is O commonly O believed O that O PB B-Chemical - O related O increases O in O serum O aminotransferase O levels O do O not O indicate O or O predict O the O development O of O significant O chronic O liver B-Disease disease I-Disease . O Here O we O report O of O two O adult O patients O with O a O long O history O of O epilepsy B-Disease treated O with O PB B-Chemical who O died O suddenly O : O one O as O consequence O of O cardiac B-Disease arrest I-Disease , O the O other O of O acute O bronchopneumonia B-Disease . O At O autopsy O , O analysis O of O liver O parenchyma O revealed O rich O portal O inflammatory O infiltrate O , O which O consisted O of O mixed O eosinophil O and O monocyte O cells O , O associated O with O several O foci O of O necrosis B-Disease surrounded O by O a O hard O ring O of O non O - O specific O granulomatous O tissue O . O Inflammatory O reactions O of O internal O and O external O hepatic O biliary O ducts O were O also O seen O . O Our O findings O illustrate O that O PB B-Chemical may O be O associated O with O chronic O liver B-Disease damage I-Disease , O which O may O lead O to O more O serious O and O deleterious O consequences O . O For O this O reason O , O each O clinician O should O recognize O this O entity O in O the O differential O diagnosis O of O PB B-Chemical - O related O asymptomatic O chronic B-Disease hepatic I-Disease enzyme I-Disease dysfunction I-Disease . O Delayed O leukoencephalopathy B-Disease with O stroke B-Disease - O like O presentation O in O chemotherapy O recipients O . O BACKGROUND O : O A O transient O leukoencephalopathy B-Disease mimicking O cerebrovascular B-Disease accident I-Disease has O been O described O as O a O complication O of O chemotherapy O , O most O commonly O in O recipients O of O intrathecal O methotrexate B-Chemical for O childhood O leukaemia B-Disease . O Recently O published O neuroimaging O data O suggest O a O common O pathophysiology O associated O with O a O variety O of O chemotherapy O agents O and O modes O of O administration O . O METHODS O : O We O reviewed O the O medical O literature O for O single O reports O and O case O series O of O patients O presenting O with O stroke B-Disease - O like O episodes O while O receiving O systemic O or O intrathecal O chemotherapy O . O We O only O included O studies O providing O detailed O neuroimaging O data O . O Patients O with O cerebrovascular B-Disease accidents I-Disease were O excluded O . O RESULTS O : O We O identified O 27 O reports O of O toxic O leukoencephalopathy B-Disease in O patients O treated O with O methotrexate B-Chemical ( O intrathecal O , O systemic O ) O , O 5 B-Chemical - I-Chemical fluorouracil I-Chemical and O its O derivative O carmofur B-Chemical , O and O capecitabine B-Chemical . O Diffusion O weighted O imaging O ( O DWI O ) O of O all O patients O revealed O well O demarcated O hyperintense O lesions B-Disease within I-Disease the I-Disease subcortical I-Disease white I-Disease matter I-Disease of O the O cerebral O hemispheres O and O the O corpus O callosum O , O corresponding O to O areas O of O decreased O proton O diffusion O on O apparent O diffusion O coefficient O ( O ADC O ) O maps O ( O available O in O 21 O / O 27 O patients O ) O . O Lesions O exceeded O the O confines O of O adjacent O vascular O territories O . O Complete O resolution O of O symptoms O within O 1 O - O 4 O days O was O accompanied O by O normalisation O of O ADC O abnormalities O . O However O , O fluid O attenuated O inversion O recovery O ( O FLAIR O ) O sequences O frequently O revealed O persistent O white B-Disease matter I-Disease abnormalities I-Disease . O CONCLUSIONS O : O Several O pathophysiological O models O of O delayed O leukoencephalopathy B-Disease after O exposure O to O intrathecal O or O systemic O chemotherapy O have O been O proposed O . O DWI O findings O in O this O cohort O are O indicative O of O cytotoxic B-Disease oedema I-Disease within I-Disease cerebral I-Disease white I-Disease matter I-Disease and O lend O support O to O an O at O least O partially O reversible O metabolic O derangement O as O the O basis O for O this O syndrome O . O Prenatal O exposure O to O fluoxetine B-Chemical induces O fetal B-Disease pulmonary I-Disease hypertension I-Disease in O the O rat O . O RATIONALE O : O Fluoxetine B-Chemical is O a O selective O serotonin B-Chemical reuptake O inhibitor O antidepressant O widely O used O by O pregnant O women O . O Epidemiological O data O suggest O that O fluoxetine B-Chemical exposure O prenatally O increases O the O prevalence O of O persistent O pulmonary B-Disease hypertension I-Disease syndrome I-Disease of O the O newborn O . O The O mechanism O responsible O for O this O effect O is O unclear O and O paradoxical O , O considering O the O current O evidence O of O a O pulmonary B-Disease hypertension I-Disease protective O fluoxetine B-Chemical effect O in O adult O rodents O . O OBJECTIVES O : O To O evaluate O the O fluoxetine B-Chemical effect O on O fetal O rat O pulmonary O vascular O smooth O muscle O mechanical O properties O and O cell O proliferation O rate O . O METHODS O : O Pregnant O rats O were O treated O with O fluoxetine B-Chemical ( O 10 O mg O / O kg O ) O from O Day O 11 O through O Day O 21 O of O gestation O . O MEASUREMENTS O AND O MAIN O RESULTS O : O Fetuses O were O delivered O by O cesarean O section O . O As O compared O with O controls O , O fluoxetine B-Chemical exposure O resulted O in O fetal B-Disease pulmonary I-Disease hypertension I-Disease as O evidenced O by O an O increase O in O the O weight O ratio O of O the O right O ventricle O to O the O left O ventricle O plus O septum O ( O P O = O 0 O . O 02 O ) O and O by O an O increase O in O pulmonary O arterial O medial O thickness O ( O P O < O 0 O . O 01 O ) O . O Postnatal O mortality O was O increased O among O experimental O animals O , O and O arterial O oxygen B-Chemical saturation O was O 96 O + O / O - O 1 O % O in O 1 O - O day O - O old O control O animals O and O significantly O lower O ( O P O < O 0 O . O 01 O ) O in O fluoxetine B-Chemical - O exposed O pups O ( O 79 O + O / O - O 2 O % O ) O . O In O vitro O , O fluoxetine B-Chemical induced O pulmonary O arterial O muscle O contraction O in O fetal O , O but O not O adult O , O animals O ( O P O < O 0 O .

O Oxytocin B-Chemical is O a O commonly O used O uterotonic O that O can O cause O significant O and O even O fatal O hypotension B-Disease , O particularly O when O given O as O a O bolus O . O The O resulting O hypotension B-Disease can O be O produced O by O a O decrease O in O systemic O vascular O resistance O or O cardiac O output O through O a O decrease O in O venous O return O . O Parturients O with O normal O volume O status O , O heart O valves O and O pulmonary O vasculature O most O often O respond O to O this O hypotension B-Disease with O a O compensatory O increase O in O heart O rate O and O stroke B-Disease volume O . O Oxytocin B-Chemical - O induced O hypotension B-Disease at O cesarean O delivery O may O be O incorrectly O attributed O to O blood B-Disease loss I-Disease . O Pulse O power O analysis O ( O also O called O " O pulse O contour O analysis O " O ) O of O an O arterial O pressure O wave O form O allows O continuous O evaluation O of O systemic O vascular O resistance O and O cardiac O output O in O real O time O , O thereby O elucidating O the O causative O factors O behind O changes O in O blood O pressure O . O Pulse O power O analysis O was O conducted O in O six O cases O of O cesarean O delivery O performed O under O neuraxial O anesthesia O . O Hypotension B-Disease in O response O to O oxytocin B-Chemical was O associated O with O a O decrease O in O systemic O vascular O resistance O and O a O compensatory O increase O in O stroke B-Disease volume O , O heart O rate O and O cardiac O output O . O Pulse O power O analysis O may O be O helpful O in O determining O the O etiology O of O and O treating O hypotension B-Disease during O cesarean O delivery O under O neuraxial O anesthesia O . O Protective O effects O of O antithrombin O on O puromycin B-Chemical aminonucleoside I-Chemical nephrosis B-Disease in O rats O . O We O investigated O the O effects O of O antithrombin O , O a O plasma O inhibitor O of O coagulation O factors O , O in O rats O with O puromycin B-Chemical aminonucleoside I-Chemical - O induced O nephrosis B-Disease , O which O is O an O experimental O model O of O human O nephrotic B-Disease syndrome I-Disease . O Antithrombin O ( O 50 O or O 500 O IU O / O kg O / O i O . O v O . O ) O was O administered O to O rats O once O a O day O for O 10 O days O immediately O after O the O injection O of O puromycin B-Chemical aminonucleoside I-Chemical ( O 50 O mg O / O kg O / O i O . O v O . O ) O . O Treatment O with O antithrombin O attenuated O the O puromycin B-Chemical aminonucleoside I-Chemical - O induced O hematological B-Disease abnormalities I-Disease . O Puromycin B-Chemical aminonucleoside I-Chemical - O induced O renal B-Disease dysfunction I-Disease and O hyperlipidemia B-Disease were O also O suppressed O . O Histopathological O examination O revealed O severe O renal B-Disease damage I-Disease such O as O proteinaceous O casts O in O tubuli O and O tubular O expansion O in O the O kidney O of O control O rats O , O while O an O improvement O of O the O damage O was O seen O in O antithrombin O - O treated O rats O . O In O addition O , O antithrombin O treatment O markedly O suppressed O puromycin B-Chemical aminonucleoside I-Chemical - O induced O apoptosis O of O renal O tubular O epithelial O cells O . O Furthermore O , O puromycin B-Chemical aminonucleoside I-Chemical - O induced O increases O in O renal O cytokine O content O were O also O decreased O . O These O findings O suggest O that O thrombin O plays O an O important O role O in O the O pathogenesis O of O puromycin B-Chemical aminonucleoside I-Chemical - O induced O nephrotic B-Disease syndrome I-Disease . O Treatment O with O antithrombin O may O be O clinically O effective O in O patients O with O nephrotic B-Disease syndrome I-Disease . O Heparin B-Chemical - O induced O thrombocytopenia B-Disease after O liver O transplantation O . O BACKGROUND O : O Unfractionated B-Chemical heparin I-Chemical sodium I-Chemical ( O UFH B-Chemical ) O or O low B-Chemical - I-Chemical molecular I-Chemical weight I-Chemical heparin I-Chemical ( O LMWH O ) O is O used O in O anticoagulant O protocols O at O several O institutions O to O prevent O thrombosis B-Disease after O liver O transplantation O . O Heparin B-Chemical - O induced O thrombocytopenia B-Disease ( O HIT B-Disease ) O is O an O adverse O immune O - O mediated O reaction O to O heparin B-Chemical , O resulting O in O platelet O count O decreases O of O more O than O 50 O % O . O The O frequencies O of O HIT B-Disease after O liver O transplantation O and O platelet O factor O 4 O / O heparin B-Chemical - O reactive O antibody O ( O HIT B-Disease antibody O ) O positivity O in O liver O transplantation O patients O , O however O , O are O unknown O . O PATIENTS O AND O METHODS O : O The O 32 O men O and O 20 O women O underwent O living O donor O liver O transplantation O . O We O started O LMWH O ( O 25 O IU O / O kg O / O h O ) O on O postoperative O day O ( O POD O ) O 1 O , O switching O to O UFH B-Chemical ( O 5000 O U O / O d O ) O on O POD O 2 O or O 3 O . O The O dose O of O UFH B-Chemical was O changed O according O to O the O activated O clotting O time O level O . O HIT B-Disease antibody O levels O were O measured O the O day O before O surgery O and O on O POD O 7 O and O 14 O . O Platelet O count O was O measured O daily O for O 3 O weeks O . O RESULTS O : O The O average O platelet O counts O preoperatively O , O and O on O POD O 7 O , O 14 O , O and O 21 O were O 65 O , O 88 O , O 149 O , O and O 169 O x O 10 O ( O 9 O ) O / O L O , O respectively O . O Two O patients O developed O hepatic O artery O thrombosis B-Disease on O POD O 11 O and O 19 O , O respectively O , O although O they O were O HIT B-Disease antibody O - O negative O and O their O platelet O counts O were O stable O . O In O 2 O other O patients O , O the O platelet O count O decreased O suddenly O from O 107 O x O 10 O ( O 9 O ) O / O L O on O POD O 4 O to O 65 O x O 10 O ( O 9 O ) O / O L O on O POD O 6 O and O from O 76 O x O 10 O ( O 9 O ) O / O L O on O POD O 7 O to O 33 O x O 10 O ( O 9 O ) O / O L O on O POD O 9 O , O respectively O . O The O heparin B-Chemical - O induced O platelet B-Disease aggregation I-Disease test O was O negative O in O these O patients O . O The O percentage O of O HIT B-Disease antibody O - O positive O patients O was O 0 O . O 5 O % O preoperatively O , O 5 O . O 6 O % O on O POD O 7 O , O and O 5 O . O 6 O % O on O POD O 14 O . O None O of O the O subjects O / O patients O developed O UFH B-Chemical - O related O HIT B-Disease . O CONCLUSIONS O : O In O our O series O , O the O occurrence O of O HIT B-Disease after O liver O transplantation O was O uncommon O . O Doxorubicin B-Chemical cardiomyopathy B-Disease - O induced O inflammation B-Disease and O apoptosis O are O attenuated O by O gene O deletion O of O the O kinin O B1 O receptor O . O Clinical O use O of O the O anthracycline B-Chemical doxorubicin B-Chemical ( O DOX B-Chemical ) O is O limited O by O its O cardiotoxic B-Disease effects O , O which O are O attributed O to O the O induction O of O apoptosis O . O To O elucidate O the O possible O role O of O the O kinin O B1 O receptor O ( O B1R O ) O during O the O development O of O DOX B-Chemical cardiomyopathy B-Disease , O we O studied O B1R O knockout O mice O ( O B1R O ( O - O / O - O ) O ) O by O investigating O cardiac O inflammation B-Disease and O apoptosis O after O induction O of O DOX B-Chemical - O induced O cardiomyopathy B-Disease . O DOX B-Chemical control O mice O showed O cardiac B-Disease dysfunction I-Disease measured O by O pressure O - O volume O loops O in O vivo O . O This O was O associated O with O a O reduced O activation O state O of O AKT O , O as O well O as O an O increased O bax O / O bcl2 O ratio O in O Western O blots O , O indicating O cardiac B-Disease apoptosis I-Disease . O Furthermore O , O mRNA O levels O of O the O proinflammatory O cytokine O interleukin O 6 O were O increased O in O the O cardiac O tissue O . O In O DOX B-Chemical B1R O ( O - O / O - O ) O mice O , O cardiac B-Disease dysfunction I-Disease was O improved O compared O to O DOX B-Chemical control O mice O , O which O was O associated O with O normalization O of O the O bax O / O bcl O - O 2 O ratio O and O interleukin O 6 O , O as O well O as O AKT O activation O state O . O These O findings O suggest O that O B1R O is O detrimental O in O DOX B-Chemical cardiomyopathy B-Disease in O that O it O mediates O the O inflammatory O response O and O apoptosis O . O These O insights O might O have O useful O implications O for O future O studies O utilizing O B1R O antagonists O for O treatment O of O human O DOX B-Chemical cardiomyopathy B-Disease . O Detailed O spectral O profile O analysis O of O penicillin B-Chemical - O induced O epileptiform B-Disease activity I-Disease in O anesthetized O rats O . O Penicillin B-Chemical model O is O a O widely O used O experimental O model O for O epilepsy B-Disease research O . O In O the O present O study O we O aimed O to O portray O a O detailed O spectral O analysis O of O penicillin B-Chemical - O induced O epileptiform B-Disease activity I-Disease in O comparison O with O basal O brain O activity O in O anesthetized O Wistar O rats O . O Male O Wistar O rats O were O anesthetized O with O i O . O p O . O urethane B-Chemical and O connected O to O an O electrocorticogram O setup O . O After O a O short O period O of O basal O activity O recording O , O epileptic B-Disease focus O was O induced O by O injecting O 400IU O / O 2 O microl O penicillin B-Chemical - I-Chemical G I-Chemical potassium I-Chemical into O the O left O lateral O ventricle O while O the O cortical O activity O was O continuously O recorded O . O Basal O activity O , O latent O period O and O the O penicillin B-Chemical - O induced O epileptiform B-Disease activity I-Disease periods O were O then O analyzed O using O both O conventional O methods O and O spectral O analysis O . O Spectral O analyses O were O conducted O by O dividing O the O whole O spectrum O into O different O frequency O bands O including O delta O , O theta O ( O slow O and O fast O ) O , O alpha O - O sigma O , O beta O ( O 1 O and O 2 O ) O and O gamma O ( O 1 O and O 2 O ) O bands O . O Our O results O show O that O the O most O affected O frequency O bands O were O delta O , O theta O , O beta O - O 2 O and O gamma O - O 2 O bands O during O the O epileptiform B-Disease activity I-Disease and O there O were O marked O differences O in O terms O of O spectral O densities O between O three O investigated O episodes O ( O basal O activity O , O latent O period O and O epileptiform B-Disease activity I-Disease ) O . O Our O results O may O help O to O analyze O novel O data O obtained O using O similar O experimental O models O and O the O simple O analysis O method O described O here O can O be O used O in O similar O studies O to O investigate O the O basic O neuronal O mechanism O of O this O or O other O types O of O experimental O epilepsies B-Disease . O High O fat B-Chemical diet O - O fed O obese B-Disease rats O are O highly O sensitive O to O doxorubicin B-Chemical - O induced O cardiotoxicity B-Disease . O Often O , O chemotherapy O by O doxorubicin B-Chemical ( O Adriamycin B-Chemical ) O is O limited O due O to O life O threatening O cardiotoxicity B-Disease in O patients O during O and O posttherapy O . O Recently O , O we O have O shown O that O moderate O diet O restriction O remarkably O protects O against O doxorubicin B-Chemical - O induced O cardiotoxicity B-Disease . O This O cardioprotection O is O accompanied O by O decreased O cardiac O oxidative O stress O and O triglycerides B-Chemical and O increased O cardiac O fatty O - O acid O oxidation O , O ATP B-Chemical synthesis O , O and O upregulated O JAK O / O STAT3 O pathway O .

O Within O the O last O several O years O , O previously O rare O liver B-Disease tumors I-Disease have O been O seen O in O young O women O using O oral B-Chemical contraceptive I-Chemical steroids B-Chemical . O The O Registry O for O Liver B-Disease Tumors I-Disease Associated O with O Oral B-Chemical Contraceptives I-Chemical at O the O University O of O California O , O Irvine O , O has O clearly O identified O 27 O cases O . O The O recent O literature O contains O 44 O case O reports O . O Common O to O these O 71 O cases O has O been O a O histopathologic O diagnosis O of O focal B-Disease nodular I-Disease hyperplasia I-Disease , O adenoma B-Disease , O hamartoma B-Disease , O and O hepatoma B-Disease . O Significant O statistical O etiologic O factors O include O prolonged O uninterrupted O usage O of O oral B-Chemical contraceptive I-Chemical steroids B-Chemical . O Eight O deaths O and O liver O rupture B-Disease in O 18 O patients O attest O to O the O seriousness O of O this O new O potentially O lethal O adverse O phenomenon O . O Ifosfamide B-Chemical continuous O infusion O without O mesna B-Chemical . O A O phase O I O trial O of O a O 14 O - O day O cycle O . O Twenty O patients O received O 27 O courses O of O ifosfamide B-Chemical administered O as O a O 24 O - O hour O continuous O infusion O for O 14 O days O without O Mesna B-Chemical . O The O goal O of O the O study O was O to O deliver O a O dose O rate O and O total O cumulative O dose O of O ifosfamide B-Chemical that O would O be O comparable O to O standard O bolus O or O short O - O term O infusions O administered O with O Mesna B-Chemical . O Dose O escalations O proceeded O from O 200 O to O 300 O , O 400 O , O 450 O , O 500 O , O and O 550 O mg O / O m2 O / O d O . O Four O patients O developed O transient O microscopic O hematuria B-Disease at O 400 O , O 450 O , O and O 500 O mg O / O m2 O / O d O . O There O were O no O instances O of O macroscopic O hematuria B-Disease . O At O 550 O mg O / O m2 O / O d O , O three O patients O experienced O nonurologic O toxicity B-Disease ; O confusion B-Disease ( O 1 O ) O , O nausea B-Disease ( O 1 O ) O , O and O Grade O 2 O leukopenia B-Disease ( O 1 O ) O . O The O recommended O dose O of O 500 O mg O / O m2 O / O d O delivers O a O total O dose O of O 7 O g O / O m2 O per O cycle O , O which O is O comparable O to O that O delivered O in O clinical O practice O for O bolus O or O short O - O term O infusion O . O Because O few O patients O received O multiple O courses O over O time O , O the O cumulative O effects O are O indeterminate O in O the O present O trial O . O The O frequency O and O predictability O of O hematuria B-Disease are O not O precise O , O and O at O least O daily O monitoring O by O urine O Hematest O is O essential O , O adding O Mesna B-Chemical to O the O infusate O in O patients O with O persistent O hematuria B-Disease . O The O protracted O infusion O schedule O for O ifosfamide B-Chemical permits O convenient O outpatient O administration O without O Mesna B-Chemical and O reduces O the O drug O cost O of O clinical O usage O of O this O agent O by O up O to O 890 O per O cycle O . O Clinical O activity O was O demonstrated O in O a O single O patient O , O but O a O comparative O trial O of O standard O bolus O schedules O with O the O protracted O infusion O schedule O will O be O necessary O to O determine O if O the O clinical O effectiveness O of O the O drug O is O maintained O . O A O case O of O ventricular B-Disease tachycardia I-Disease related O to O caffeine B-Chemical pretreatment O . O Suboptimal O seizure B-Disease duration O is O commonly O encountered O in O electroconvulsive O therapy O practice O , O especially O in O older O patients O with O higher O seizure B-Disease thresholds O . O Intravenous O caffeine B-Chemical is O commonly O used O to O improve O seizure B-Disease duration O and O quality O in O such O patients O and O is O generally O well O tolerated O aside O from O occasional O reports O of O relatively O benign O ventricular B-Disease ectopy I-Disease . O We O describe O a O patient O with O no O previous O history O of O cardiac B-Disease disease I-Disease or O arrhythmia B-Disease who O developed O sustained O bigeminy O and O 2 O brief O runs O of O ventricular B-Disease tachycardia I-Disease after O caffeine B-Chemical administration O . O Although O intravenous O caffeine B-Chemical is O generally O well O tolerated O , O the O clinician O should O be O aware O of O the O potential O for O unpredictable O and O serious O ventricular B-Disease arrhythmias I-Disease . O Fatal O haemopericardium B-Disease and O gastrointestinal B-Disease haemorrhage I-Disease due O to O possible O interaction O of O cranberry O juice O with O warfarin B-Chemical . O We O report O a O case O of O fatal O internal O haemorrhage B-Disease in O an O elderly O man O who O consumed O only O cranberry O juice O for O two O weeks O while O maintaining O his O usual O dosage O of O warfarin B-Chemical . O We O propose O that O naturally O occurring O compounds O such O as O flavonoids B-Chemical , O which O are O present O in O fruit O juices O , O may O increase O the O potency O of O warfarin B-Chemical by O competing O for O the O enzymes O that O normally O inactivate O warfarin B-Chemical . O While O traditionally O regarded O as O foodstuffs O , O consumption O of O fruit O juices O should O be O considered O when O patients O develop O adverse O drug O reactions O . O Effect O of O increasing O intraperitoneal O infusion O rates O on O bupropion B-Chemical hydrochloride I-Chemical - O induced O seizures B-Disease in O mice O . O BACKGROUND O : O It O is O not O known O if O there O is O a O relationship O between O input O rate O and O incidence O of O bupropion B-Chemical - O induced O seizures B-Disease . O This O is O important O , O since O different O controlled O release O formulations O of O bupropion B-Chemical release O the O active O drug O at O different O rates O . O METHODS O : O We O investigated O the O effect O of O varying O the O intraperitoneal O infusion O rates O of O bupropion B-Chemical HCl I-Chemical 120 O mg O / O kg O , O a O known O convulsive B-Disease dose O 50 O ( O CD50 O ) O , O on O the O incidence O and O severity O of O bupropion B-Chemical - O induced O convulsions B-Disease in O the O Swiss O albino O mice O . O A O total O of O 69 O mice O , O approximately O 7 O weeks O of O age O , O and O weighing O 21 O . O 0 O to O 29 O . O 1 O g O were O randomly O assigned O to O bupropion B-Chemical HCl I-Chemical 120 O mg O / O kg O treatment O by O intraperitoneal O ( O IP O ) O administration O in O 7 O groups O ( O 9 O to O 10 O animals O per O group O ) O . O Bupropion B-Chemical HCl I-Chemical was O infused O through O a O surgically O implanted O IP O dosing O catheter O with O infusions O in O each O group O of O 0 O min O , O 15 O min O , O 30 O min O , O 60 O min O , O 90 O min O , O 120 O min O , O and O 240 O min O . O The O number O , O time O of O onset O , O duration O and O the O intensity O of O the O convulsions B-Disease or O absence O of O convulsions B-Disease were O recorded O . O RESULTS O : O The O results O showed O that O IP O administration O of O bupropion B-Chemical HCl I-Chemical 120 O mg O / O kg O by O bolus O injection O induced O convulsions B-Disease in O 6 O out O of O 10 O mice O ( O 60 O % O of O convulsing O mice O ) O in O group O 1 O . O Logistic O regression O analysis O revealed O that O infusion O time O was O significant O ( O p O = O 0 O . O 0004 O ; O odds O ratio O = O 0 O . O 974 O ) O and O increasing O the O IP O infusion O time O of O bupropion B-Chemical HCl I-Chemical 120 O mg O / O kg O was O associated O with O a O 91 O % O reduced O odds O of O convulsions B-Disease at O infusion O times O of O 15 O to O 90 O min O compared O to O bolus O injection O . O Further O increase O in O infusion O time O resulted O in O further O reduction O in O the O odds O of O convulsions B-Disease to O 99 O . O 8 O % O reduction O at O 240 O min O . O CONCLUSION O : O In O conclusion O , O the O demonstration O of O an O inverse O relationship O between O infusion O time O of O a O fixed O and O convulsive B-Disease dose O of O bupropion B-Chemical and O the O risk O of O convulsions B-Disease in O a O prospective O study O is O novel O .

O SELECTION O CRITERIA O : O Randomised O double O - O blind O trials O of O HT O versus O placebo O , O taken O for O at O least O one O year O by O perimenopausal O or O postmenopausal O women O . O HT O included O oestrogens B-Chemical , O with O or O without O progestogens B-Chemical , O via O oral O , O transdermal O , O subcutaneous O or O transnasal O routes O . O DATA O COLLECTION O AND O ANALYSIS O : O Two O authors O independently O assessed O trial O quality O and O extracted O data O . O MAIN O RESULTS O : O Nineteen O trials O involving O 41 O , O 904 O women O were O included O . O In O relatively O healthy O women O , O combined O continuous O HT O significantly O increased O the O risk O of O venous B-Disease thrombo I-Disease - I-Disease embolism I-Disease or O coronary O event O ( O after O one O year O ' O s O use O ) O , O stroke B-Disease ( O after O three O years O ) O , O breast B-Disease cancer I-Disease and O gallbladder B-Disease disease I-Disease .

O Acute B-Disease renal I-Disease failure I-Disease in O patients O with O AIDS B-Disease on O tenofovir B-Chemical while O receiving O prolonged O vancomycin B-Chemical course O for O osteomyelitis B-Disease . O Renal B-Disease failure I-Disease developed O after O a O prolonged O course O of O vancomycin B-Chemical therapy O in O 2 O patients O who O were O receiving O tenofovir B-Chemical disoproxil I-Chemical fumarate I-Chemical as O part O of O an O antiretroviral O regimen O . O Tenofovir B-Chemical has O been O implicated O in O the O development O of O Fanconi B-Disease syndrome I-Disease and O renal B-Disease insufficiency I-Disease because O of O its O effects O on O the O proximal O renal O tubule O . O Vancomycin B-Chemical nephrotoxicity B-Disease is O infrequent O but O may O result O from O coadministration O with O a O nephrotoxic B-Disease agent O . O Clinicians O should O be O aware O that O tenofovir B-Chemical may O raise O the O risk O of O renal B-Disease failure I-Disease during O prolonged O administration O of O vancomycin B-Chemical . O Recurrent O dysosmia B-Disease induced O by O pyrazinamide B-Chemical .

O In O rare O cases O , O alterations O in O taste O and O smell O function O have O been O reported O for O pyrazinamide B-Chemical when O combined O with O other O drugs O . O We O report O a O case O of O reversible O olfactory B-Disease disorder I-Disease related O to O pyrazinamide B-Chemical in O a O woman O , O with O a O positive O rechallenge O . O The O patient O presented O every O day O a O sensation O of O smelling O something O burning O 15 O min O after O drug O intake O .

O day O ( O - O 1 O ) O ip O ) O in O mPGES O - O 1 O + O / O + O mice O led O to O a O marked O polyuria B-Disease with O hyposmotic O urine O . O This O was O associated O with O elevated O renal O mPGES O - O 1 O protein O expression O and O increased O urine O PGE B-Chemical ( I-Chemical 2 I-Chemical ) I-Chemical excretion O . O In O contrast O , O mPGES O - O 1 O - O / O - O mice O were O largely O resistant O to O lithium B-Chemical - O induced O polyuria B-Disease and O a O urine O concentrating O defect O , O accompanied O by O nearly O complete O blockade O of O high O urine O PGE B-Chemical ( I-Chemical 2 I-Chemical ) I-Chemical and O cAMP O output O . O Immunoblotting O , O immunohistochemistry O , O and O quantitative O ( O q O ) O RT O - O PCR O consistently O detected O a O significant O decrease O in O aquaporin O - O 2 O ( O AQP2 O ) O protein O expression O in O both O the O renal O cortex O and O medulla O of O lithium B-Chemical - O treated O + O / O + O mice O .

O Fenoldopam B-Chemical mesylate I-Chemical is O a O specific O DA1 O receptor O agonist O that O lowers O blood O pressure O by O vasodilatation O . O The O hypothesis O that O fenoldopam B-Chemical could O be O used O to O induce O hypotension B-Disease and O preserve O blood O flow O to O the O kidney O was O tested O .

O METHODS O : O Several O biomedical O databases O were O searched O including O MEDLINE O , O Cochrane O and O Ovid O . O The O main O search O terms O utilized O were O case O report O and O levofloxacin B-Chemical . O The O search O was O limited O to O studies O published O in O English O . O RESULTS O : O Six O cases O of O levofloxacin B-Chemical - O induced O seizures B-Disease have O been O reported O in O the O literature O . O Drug O - O drug O interactions O related O to O the O inhibition O of O CYP1A2 O by O levofloxacin B-Chemical are O likely O involved O in O the O clinical O outcome O of O these O cases O . O CONCLUSIONS O : O Clinicians O are O exhorted O to O pay O close O attention O when O initiating O levofloxacin B-Chemical therapy O in O patients O taking O medications O with O epileptogenic O properties O that O are O CYP1A2 O substrates O . O Dextran B-Chemical - O etodolac B-Chemical conjugates O : O synthesis O , O in O vitro O and O in O vivo O evaluation O . O Etodolac B-Chemical ( O E B-Chemical ) O , O is O a O non O - O narcotic O analgesic O and O antiinflammatory O drug O . O A O biodegradable O polymer O dextran B-Chemical has O been O utilized O as O a O carrier O for O synthesis O of O etodolac B-Chemical - O dextran B-Chemical conjugates O ( O ED O ) O to O improve O its O aqueous O solubility O and O reduce O gastrointestinal O side O effects O .

O Biological O evaluation O suggested O that O conjugates O ( O ED1 O - O ED4 O ) O retained O comparable O analgesic O and O antiinflammatory O activities O with O remarkably O reduced O ulcerogenicity O as O compared O to O their O parent O drug O - O - O etodolac B-Chemical . O The O antiarrhythmic O effect O and O possible O ionic O mechanisms O of O pilocarpine B-Chemical on O animal O models O . O This O study O was O designed O to O evaluate O the O effects O of O pilocarpine B-Chemical and O explore O the O underlying O ionic O mechanism O , O using O both O aconitine B-Chemical - O induced O rat O and O ouabain B-Chemical - O induced O guinea O pig O arrhythmia B-Disease models O .

O Effect O of O Hibiscus B-Chemical rosa I-Chemical sinensis I-Chemical on O reserpine B-Chemical - O induced O neurobehavioral O and O biochemical O alterations O in O rats O . O Effect O of O methanolic O extract O of O Hibiscus B-Chemical rosa I-Chemical sinensis I-Chemical ( O 100 O - O 300 O mg O / O kg O ) O was O studied O on O reserpine B-Chemical - O induced O orofacial O dyskinesia B-Disease and O neurochemical O alterations O . O The O rats O were O treated O with O intraperitoneal O reserpine B-Chemical ( O 1 O mg O / O kg O , O ip O ) O for O 3 O days O every O other O day O . O On O day O 5 O , O vacuous O chewing O movements O and O tongue O protrusions O were O counted O for O 5 O min O . O Reserpine B-Chemical treated O rats O significantly O developed O vacuous O chewing O movements O and O tongue O protrusions O however O , O coadministration O of O Hibiscus B-Chemical rosa I-Chemical sinensis I-Chemical roots O extract O ( O 100 O , O 200 O and O 300 O mg O / O kg O , O per O orally O ) O attenuated O the O effects O . O Biochemical O analysis O of O brain O revealed O that O the O reserpine B-Chemical treatment O significantly O increased O lipid O peroxidation O and O decreased O levels O of O superoxide B-Chemical dismutase O ( O SOD O ) O , O catalase O ( O CAT O ) O and O glutathione B-Chemical reductase O ( O GSH O ) O , O an O index O of O oxidative O stress O process O .

O The O results O of O the O present O study O suggested O that O Hibiscus B-Chemical rosa I-Chemical sinensis I-Chemical had O a O protective O role O against O reserpine B-Chemical - O induced O orofacial O dyskinesia B-Disease and O oxidative O stress O . O Dynamic O response O of O blood O vessel O in O acute B-Disease renal I-Disease failure I-Disease . O In O this O study O we O postulated O that O during O acute B-Disease renal I-Disease failure I-Disease induced O by O gentamicin B-Chemical the O transient O or O dynamic O response O of O blood O vessels O could O be O affected O , O and O that O antioxidants O can O prevent O the O changes O in O dynamic O responses O of O blood O vessels O . O The O new O approach O to O ex O vivo O blood O vessel O experiments O in O which O not O only O the O end O points O of O vessels O response O within O the O time O interval O is O considered O , O but O also O dynamics O of O this O response O , O was O used O in O this O paper O . O Our O results O confirm O the O alteration O in O dynamic O response O of O blood O vessels O during O the O change O of O pressure O in O gentamicin B-Chemical - O treated O animals O . O The O beneficial O effects O of O vitamin B-Chemical C I-Chemical administration O to O gentamicin B-Chemical - O treated O animals O are O also O confirmed O through O : O lower O level O of O blood O urea B-Chemical and O creatinine B-Chemical and O higher O level O of O potassium B-Chemical . O The O pressure O dynamic O responses O of O isolated O blood O vessels O show O a O faster O pressure O change O in O gentamicin B-Chemical - O treated O animals O ( O 8 O .

O Vitamin B-Chemical C I-Chemical administration O induced O slowdown O of O pressure O change O back O to O the O control O values O . O The O pressure O dynamic O properties O , O quantitatively O defined O by O comparative O pressure O dynamic O and O total O pressure O dynamic O , O confirm O the O alteration O in O dynamic O response O of O blood O vessels O during O the O change O of O pressure O in O gentamicin B-Chemical - O treated O animals O and O beneficial O effects O of O vitamin B-Chemical C I-Chemical administration O . O Reversible O myocardial B-Disease hypertrophy I-Disease induced O by O tacrolimus B-Chemical in O a O pediatric O heart O transplant O recipient O : O case O report O . O Tacrolimus B-Chemical is O a O potent O immunosuppressant O that O is O frequently O used O in O organ O transplantation O . O However O , O adverse O effects O include O cardiac B-Disease toxicity I-Disease . O Herein O we O describe O transient O myocardial B-Disease hypertrophy I-Disease induced O by O tacrolimus B-Chemical after O heart O transplantation O . O The O hypertrophy B-Disease caused O no O clinical O symptoms O but O was O noted O because O of O elevation O of O plasma O brain O natriuretic O peptide O concentration O and O confirmed O at O echocardiography O . O Initially O , O allograft O rejection O was O feared O ; O however O , O myocardial O biopsy O samples O revealed O only O interstitial O edema B-Disease and O mild O myocardial B-Disease hypertrophy I-Disease ; O neither O cellular O nor O humoral O rejection O was O detected O . O The O blood O tacrolimus B-Chemical concentration O was O higher O than O usual O at O that O time O ; O thus O , O tacrolimus B-Chemical dosage O was O reduced O . O Myocardial B-Disease hypertrophy I-Disease completely O resolved O upon O reducing O the O target O concentration O of O tacrolimus B-Chemical and O did O not O recur O , O as O confirmed O at O echocardiography O and O myocardial O biopsy O . O Thus O , O we O conclude O that O tacrolimus B-Chemical induces O reversible O myocardial B-Disease hypertrophy I-Disease . O In O patients O receiving O tacrolimus B-Chemical therapy O , O blood O concentration O should O be O carefully O controlled O and O extreme O attention O paid O to O cardiac O involvement O . O Nimodipine B-Chemical prevents O memory B-Disease impairment I-Disease caused O by O nitroglycerin B-Chemical - O induced O hypotension B-Disease in O adult O mice O . O BACKGROUND O : O Hypotension B-Disease and O a O resultant O decrease O in O cerebral O blood O flow O have O been O implicated O in O the O development O of O cognitive B-Disease dysfunction I-Disease . O We O tested O the O hypothesis O that O nimodipine B-Chemical ( O NIMO B-Chemical ) O administered O at O the O onset O of O nitroglycerin B-Chemical ( O NTG B-Chemical ) O - O induced O hypotension B-Disease would O preserve O long O - O term O associative O memory O .

O High O - O dose O tranexamic B-Chemical Acid I-Chemical is O associated O with O nonischemic O clinical O seizures B-Disease in O cardiac O surgical O patients O . O BACKGROUND O : O In O 2 O separate O centers O , O we O observed O a O notable O increase O in O the O incidence O of O postoperative O convulsive B-Disease seizures B-Disease from O 1 O . O 3 O % O to O 3 O . O 8 O % O in O patients O having O undergone O major O cardiac O surgical O procedures O . O These O events O were O temporally O coincident O with O the O initial O use O of O high O - O dose O tranexamic B-Chemical acid I-Chemical ( O TXA B-Chemical ) O therapy O after O withdrawal O of O aprotinin O from O general O clinical O usage O . O The O purpose O of O this O review O was O to O perform O a O retrospective O analysis O to O examine O whether O there O was O a O relation O between O TXA B-Chemical usage O and O seizures B-Disease after O cardiac O surgery O . O METHODS O : O An O in O - O depth O chart O review O was O undertaken O in O all O 24 O patients O who O developed O perioperative O seizures B-Disease . O Electroencephalographic O activity O was O recorded O in O 11 O of O these O patients O , O and O all O patients O had O a O formal O neurological O evaluation O and O brain O imaging O studies O . O RESULTS O : O Twenty O - O one O of O the O 24 O patients O did O not O have O evidence O of O new O cerebral B-Disease ischemic I-Disease injury I-Disease , O but O seizures B-Disease were O likely O due O to O ischemic B-Disease brain I-Disease injury I-Disease in O 3 O patients O . O All O patients O with O seizures B-Disease did O not O have O permanent O neurological B-Disease abnormalities I-Disease . O All O 24 O patients O with O seizures B-Disease received O high O doses O of O TXA B-Chemical intraoperatively O ranging O from O 61 O to O 259 O mg O / O kg O , O had O a O mean O age O of O 69 O . O 9 O years O , O and O 21 O of O 24 O had O undergone O open O chamber O rather O than O coronary O bypass O procedures O . O All O but O one O patient O were O managed O using O cardiopulmonary O bypass O . O No O evidence O of O brain B-Disease ischemic I-Disease , O metabolic O , O or O hyperthermia B-Disease - O induced O causes O for O their O seizures B-Disease was O apparent O . O CONCLUSION O : O Our O results O suggest O that O use O of O high O - O dose O TXA B-Chemical in O older O patients O in O conjunction O with O cardiopulmonary O bypass O and O open O - O chamber O cardiac O surgery O is O associated O with O clinical O seizures B-Disease in O susceptible O patients O . O Electrocardiographic O changes O and O cardiac B-Disease arrhythmias I-Disease in O patients O receiving O psychotropic O drugs O . O Eight O patients O had O cardiac O manifestations O that O were O life O - O threatening O in O five O while O taking O psychotropic O drugs O , O either O phenothiazines B-Chemical or O tricyclic O antidepressants O . O Although O most O patients O were O receiving O several O drugs O , O Mellaril B-Chemical ( O thioridazine B-Chemical ) O appeared O to O be O responsible O for O five O cases O of O ventricular B-Disease tachycardia I-Disease , O one O of O which O was O fatal O in O a O 35 O year O old O woman O . O Supraventricular B-Disease tachycardia I-Disease developed O in O one O patient O receiving O Thorazine B-Chemical ( O chlorpromazine B-Chemical ) O . O Aventyl B-Chemical ( O nortriptyline B-Chemical ) O and O Elavil B-Chemical ( O amitriptyline B-Chemical ) O each O produced O left B-Disease bundle I-Disease branch I-Disease block I-Disease in O a O 73 O year O old O woman O . O Electrocardiographic O T O and O U O wave O abnormalities O were O present O in O most O patients O . O The O ventricular B-Disease arrhythmias I-Disease responded O to O intravenous O administration O of O lidocaine B-Chemical and O to O direct O current O electric O shock O ; O ventricular O pacing O was O required O in O some O instances O and O intravenous O administration O of O propranolol B-Chemical combined O with O ventricular O pacing O in O one O . O The O tachyarrhythmias B-Disease generally O subsided O within O 48 O hours O after O administration O of O the O drugs O was O stopped O . O Five O of O the O eight O patients O were O 50 O years O of O age O or O younger O ; O only O one O clearly O had O antecedent O heart B-Disease disease I-Disease . O Major O cardiac B-Disease arrhythmias I-Disease are O a O potential O hazard O in O patients O without O heart B-Disease disease I-Disease who O are O receiving O customary O therapeutic O doses O of O psychotropic O drugs O . O A O prospective O clinical O trial O is O suggested O to O quantify O the O risk O of O cardiac B-Disease complications I-Disease to O patients O receiving O phenothiazines B-Chemical or O tricyclic O antidepressant O drugs O . O Sensitivity O of O erythroid O progenitor O colonies O to O erythropoietin O in O azidothymidine B-Chemical treated O immunodeficient B-Disease mice O . O The O anaemia B-Disease induced O by O 3 B-Chemical ' I-Chemical - I-Chemical azido I-Chemical - I-Chemical 3 I-Chemical ' I-Chemical dideoxythymidine I-Chemical ( O AZT B-Chemical ) O is O poorly O understood O . O We O have O used O a O murine O model O of O AIDS B-Disease , O infection B-Disease of O female O C57BL O / O 6 O mice O with O LP O - O BM5 O murine O leukaemia B-Disease ( O MuLV O ) O virus O , O to O determine O if O AZT B-Chemical - O induced O anaemia B-Disease is O due O , O in O part O , O to O decreased O responsiveness O of O erythropoietic O precursors O ( O BFU O - O e O ) O to O erythropoietin O ( O EPO O ) O . O Mice O in O the O early O stage O of O LP O - O BM5 O MuLV O disease O were O given O AZT B-Chemical in O their O drinking O water O at O 1 O . O 0 O and O 2 O . O 5 O mg O / O ml O . O AZT B-Chemical produced O anaemia B-Disease in O both O groups O , O in O a O dose O - O dependent O fashion O . O Despite O the O anaemia B-Disease , O the O number O of O splenic O and O bone O marrow O BFU O - O e O in O AZT B-Chemical treated O mice O increased O up O to O five O - O fold O over O levels O observed O in O infected O untreated O animals O after O 15 O d O of O treatment O . O Colony O formation O by O splenic O and O bone O marrow O BFUe O was O stimulated O at O lower O concentrations O of O EPO O in O mice O receiving O AZT B-Chemical for O 15 O d O than O for O infected O , O untreated O mice O . O By O day O 30 O , O sensitivity O of O both O splenic O and O bone O marrow O BFU O - O e O of O treated O animals O returned O to O that O observed O from O cells O of O infected O untreated O animals O . O The O mean O plasma O levels O of O EPO O observed O in O AZT B-Chemical treated O mice O were O appropriate O for O the O degree O of O anaemia B-Disease observed O when O compared O with O phenylhydrazine B-Chemical ( O PHZ B-Chemical ) O treated O mice O . O The O numbers O of O BFU O - O e O and O the O percentage O of O bone O marrow O erythroblasts O observed O were O comparable O in O AZT B-Chemical and O PHZ B-Chemical treated O mice O with O similar O degrees O of O anaemia B-Disease . O However O , O reticulocytosis B-Disease was O inappropriate O for O the O degree O of O anaemia B-Disease observed O in O AZT B-Chemical treated O infected O mice O . O AZT B-Chemical - O induced O peripheral O anaemia B-Disease in O the O face O of O increased O numbers O of O BFU O - O e O and O increased O levels O of O plasma O EPO O suggest O a O lesion O in O terminal O differentiation O . O Sedation O depth O during O spinal O anesthesia O and O the O development O of O postoperative B-Disease delirium I-Disease in O elderly O patients O undergoing O hip B-Disease fracture I-Disease repair O . O OBJECTIVE O : O To O determine O whether O limiting O intraoperative O sedation O depth O during O spinal O anesthesia O for O hip B-Disease fracture I-Disease repair O in O elderly O patients O can O decrease O the O prevalence O of O postoperative B-Disease delirium I-Disease . O PATIENTS O AND O METHODS O : O We O performed O a O double O - O blind O , O randomized O controlled O trial O at O an O academic O medical O center O of O elderly O patients O ( O > O or O = O 65 O years O ) O without O preoperative O delirium B-Disease or O severe O dementia B-Disease who O underwent O hip B-Disease fracture I-Disease repair O under O spinal O anesthesia O with O propofol B-Chemical sedation O . O Sedation O depth O was O titrated O using O processed O electroencephalography O with O the O bispectral O index O ( O BIS O ) O , O and O patients O were O randomized O to O receive O either O deep O ( O BIS O , O approximately O 50 O ) O or O light O ( O BIS O , O > O or O = O 80 O ) O sedation O . O Postoperative B-Disease delirium I-Disease was O assessed O as O defined O by O Diagnostic O and O Statistical O Manual O of O Mental B-Disease Disorders I-Disease ( O Third O Edition O Revised O ) O criteria O using O the O Confusion O Assessment O Method O beginning O at O any O time O from O the O second O day O after O surgery O . O RESULTS O : O From O April O 2 O , O 2005 O , O through O October O 30 O , O 2008 O , O a O total O of O 114 O patients O were O randomized O . O The O prevalence O of O postoperative B-Disease delirium I-Disease was O significantly O lower O in O the O light O sedation O group O ( O 11 O / O 57 O [ O 19 O % O ] O vs O 23 O / O 57 O [ O 40 O % O ] O in O the O deep O sedation O group O ; O P O = O .

O CONCLUSION O : O The O use O of O light O propofol B-Chemical sedation O decreased O the O prevalence O of O postoperative B-Disease delirium I-Disease by O 50 O % O compared O with O deep O sedation O . O Limiting O depth O of O sedation O during O spinal O anesthesia O is O a O simple O , O safe O , O and O cost O - O effective O intervention O for O preventing O postoperative B-Disease delirium I-Disease in O elderly O patients O that O could O be O widely O and O readily O adopted O . O The O protective O role O of O Nrf2 O in O streptozotocin B-Chemical - O induced O diabetic B-Disease nephropathy I-Disease . O OBJECTIVE O : O Diabetic B-Disease nephropathy I-Disease is O one O of O the O major O causes O of O renal B-Disease failure I-Disease , O which O is O accompanied O by O the O production O of O reactive O oxygen B-Chemical species O ( O ROS O ) O . O Nrf2 O is O the O primary O transcription O factor O that O controls O the O antioxidant O response O essential O for O maintaining O cellular O redox O homeostasis O . O Here O , O we O report O our O findings O demonstrating O a O protective O role O of O Nrf2 O against O diabetic B-Disease nephropathy I-Disease . O RESEARCH O DESIGN O AND O METHODS O : O We O explore O the O protective O role O of O Nrf2 O against O diabetic B-Disease nephropathy I-Disease using O human O kidney O biopsy O tissues O from O diabetic B-Disease nephropathy I-Disease patients O , O a O streptozotocin B-Chemical - O induced O diabetic B-Disease nephropathy I-Disease model O in O Nrf2 O ( O - O / O - O ) O mice O , O and O cultured O human O mesangial O cells O . O RESULTS O : O The O glomeruli O of O human O diabetic B-Disease nephropathy I-Disease patients O were O under O oxidative O stress O and O had O elevated O Nrf2 O levels O . O In O the O animal O study O , O Nrf2 O was O demonstrated O to O be O crucial O in O ameliorating O streptozotocin B-Chemical - O induced O renal B-Disease damage I-Disease . O This O is O evident O by O Nrf2 O ( O - O / O - O ) O mice O having O higher O ROS O production O and O suffering O from O greater O oxidative O DNA O damage O and O renal B-Disease injury I-Disease compared O with O Nrf2 O ( O + O / O + O ) O mice O . O Mechanistic O studies O in O both O in O vivo O and O in O vitro O systems O showed O that O the O Nrf2 O - O mediated O protection O against O diabetic B-Disease nephropathy I-Disease is O , O at O least O , O partially O through O inhibition O of O transforming O growth O factor O - O beta1 O ( O TGF O - O beta1 O ) O and O reduction O of O extracellular O matrix O production O . O In O human O renal O mesangial O cells O , O high O glucose B-Chemical induced O ROS O production O and O activated O expression O of O Nrf2 O and O its O downstream O genes O . O Furthermore O , O activation O or O overexpression O of O Nrf2 O inhibited O the O promoter O activity O of O TGF O - O beta1 O in O a O dose O - O dependent O manner O , O whereas O knockdown O of O Nrf2 O by O siRNA O enhanced O TGF O - O beta1 O transcription O and O fibronectin O production O . O CONCLUSIONS O : O This O work O clearly O indicates O a O protective O role O of O Nrf2 O in O diabetic B-Disease nephropathy I-Disease , O suggesting O that O dietary O or O therapeutic O activation O of O Nrf2 O could O be O used O as O a O strategy O to O prevent O or O slow O down O the O progression O of O diabetic B-Disease nephropathy I-Disease . O Metformin B-Chemical prevents O experimental O gentamicin B-Chemical - O induced O nephropathy B-Disease by O a O mitochondria O - O dependent O pathway O . O The O antidiabetic O drug O metformin B-Chemical can O diminish O apoptosis O induced O by O oxidative O stress O in O endothelial O cells O and O prevent O vascular B-Disease dysfunction I-Disease even O in O nondiabetic O patients O . O Here O we O tested O whether O it O has O a O beneficial O effect O in O a O rat O model O of O gentamicin B-Chemical toxicity B-Disease . O Mitochondrial O analysis O , O respiration O intensity O , O levels O of O reactive O oxygen B-Chemical species O , O permeability O transition O , O and O cytochrome O c O release O were O assessed O 3 O and O 6 O days O after O gentamicin B-Chemical administration O . O Metformin B-Chemical treatment O fully O blocked O gentamicin B-Chemical - O mediated O acute B-Disease renal I-Disease failure I-Disease . O This O was O accompanied O by O a O lower O activity O of O N O - O acetyl O - O beta O - O D O - O glucosaminidase O , O together O with O a O decrease O of O lipid O peroxidation O and O increase O of O antioxidant O systems O . O Metformin B-Chemical also O protected O the O kidney O from O histological O damage O 6 O days O after O gentamicin B-Chemical administration O . O These O in O vivo O markers O of O kidney B-Disease dysfunction I-Disease and O their O correction O by O metformin B-Chemical were O complemented O by O in O vitro O studies O of O mitochondrial O function O . O We O found O that O gentamicin B-Chemical treatment O depleted O respiratory O components O ( O cytochrome O c O , O NADH O ) O , O probably O due O to O the O opening O of O mitochondrial O transition O pores O . O These O injuries O , O partly O mediated O by O a O rise O in O reactive O oxygen B-Chemical species O from O the O electron O transfer O chain O , O were O significantly O decreased O by O metformin B-Chemical . O Thus O , O our O study O suggests O that O pleiotropic O effects O of O metformin B-Chemical can O lessen O gentamicin B-Chemical nephrotoxicity B-Disease and O improve O mitochondrial O homeostasis O . O Risk O of O nephropathy B-Disease after O consumption O of O nonionic O contrast B-Chemical media I-Chemical by O children O undergoing O cardiac O angiography O : O a O prospective O study O . O Despite O increasing O reports O on O nonionic O contrast B-Chemical media I-Chemical - O induced O nephropathy B-Disease ( O CIN B-Disease ) O in O hospitalized O adult O patients O during O cardiac O procedures O , O the O studies O in O pediatrics O are O limited O , O with O even O less O focus O on O possible O predisposing O factors O and O preventive O measures O for O patients O undergoing O cardiac O angiography O . O This O prospective O study O determined O the O incidence O of O CIN B-Disease for O two O nonionic O contrast B-Chemical media I-Chemical ( O CM B-Chemical ) O , O iopromide B-Chemical and O iohexol B-Chemical , O among O 80 O patients O younger O than O 18 O years O and O compared O the O rates O for O this O complication O in O relation O to O the O type O and O dosage O of O CM B-Chemical and O the O presence O of O cyanosis B-Disease . O The O 80 O patients O in O the O study O consecutively O received O either O iopromide B-Chemical ( O group O A O , O n O = O 40 O ) O or O iohexol B-Chemical ( O group O B O , O n O = O 40 O ) O . O Serum O sodium B-Chemical ( O Na B-Chemical ) O , O potassium B-Chemical ( O K B-Chemical ) O , O and O creatinine B-Chemical ( O Cr B-Chemical ) O were O measured O 24 O h O before O angiography O as O baseline O values O , O then O measured O again O at O 12 O - O , O 24 O - O , O and O 48 O - O h O intervals O after O CM B-Chemical use O . O Urine O samples O for O Na B-Chemical and O Cr B-Chemical also O were O checked O at O the O same O intervals O . O Risk O of O renal B-Disease failure I-Disease , O Injury B-Disease to I-Disease the I-Disease kidney I-Disease , O Failure B-Disease of I-Disease kidney I-Disease function I-Disease , O Loss B-Disease of I-Disease kidney I-Disease function I-Disease , O and O End O - O stage O renal B-Disease damage I-Disease ( O RIFLE O criteria O ) O were O used O to O define O CIN B-Disease and O its O incidence O in O the O study O population O . O Accordingly O , O among O the O 15 O CIN B-Disease patients O ( O 18 O . O 75 O % O ) O , O 7 O . O 5 O % O of O the O patients O in O group O A O had O increased O risk O and O 3 O .

O The O effect O of O isoflurane B-Chemical - O induced O hypotension B-Disease on O glomerular O function O and O renal O blood O flow O was O investigated O in O 20 O human O subjects O . O Glomerular O filtration O rate O ( O GFR O ) O and O effective O renal O plasma O flow O ( O ERPF O ) O were O measured O by O inulin O and O para B-Chemical - I-Chemical aminohippurate I-Chemical ( O PAH B-Chemical ) O clearance O , O respectively O . O Anesthesia O was O maintained O with O fentanyl B-Chemical , O nitrous B-Chemical oxide I-Chemical , O oxygen B-Chemical , O and O isoflurane B-Chemical .

O A O cross O - O sectional O evaluation O of O the O effect O of O risperidone B-Chemical and O selective O serotonin B-Chemical reuptake O inhibitors O on O bone O mineral O density O in O boys O . O OBJECTIVE O : O The O aim O of O the O present O study O was O to O investigate O the O effect O of O risperidone B-Chemical - O induced O hyperprolactinemia B-Disease on O trabecular O bone O mineral O density O ( O BMD O ) O in O children O and O adolescents O . O METHOD O : O Medically O healthy O 7 O - O to O 17 O - O year O - O old O males O chronically O treated O , O in O a O naturalistic O setting O , O with O risperidone B-Chemical were O recruited O for O this O cross O - O sectional O study O through O child O psychiatry O outpatient O clinics O between O November O 2005 O and O June O 2007 O . O Anthropometric O measurements O and O laboratory O testing O were O conducted O . O The O clinical O diagnoses O were O based O on O chart O review O , O and O developmental O and O treatment O history O was O obtained O from O the O medical O record O . O Volumetric O BMD O of O the O ultradistal O radius O was O measured O using O peripheral O quantitative O computed O tomography O , O and O areal O BMD O of O the O lumbar O spine O was O estimated O using O dual O - O energy O x O - O ray O absorptiometry O . O RESULTS O : O Hyperprolactinemia B-Disease was O present O in O 49 O % O of O 83 O boys O ( O n O = O 41 O ) O treated O with O risperidone B-Chemical for O a O mean O of O 2 O . O 9 O years O . O Serum O testosterone B-Chemical concentration O increased O with O pubertal O status O but O was O not O affected O by O hyperprolactinemia B-Disease . O As O expected O , O bone O mineral O content O and O BMD O increased O with O sexual O maturity O . O After O adjusting O for O the O stage O of O sexual O development O and O height O and O BMI O z O scores O , O serum O prolactin O was O negatively O associated O with O trabecular O volumetric O BMD O at O the O ultradistal O radius O ( O P O < O . O 03 O ) O . O Controlling O for O relevant O covariates O , O we O also O found O treatment O with O selective O serotonin B-Chemical reuptake O inhibitors O ( O SSRIs O ) O to O be O associated O with O lower O trabecular O BMD O at O the O radius O ( O P O = O . O 03 O ) O and O BMD O z O score O at O the O lumbar O spine O ( O P O < O . O 05 O ) O . O These O findings O became O more O marked O when O the O analysis O was O restricted O to O non O - O Hispanic O white O patients O . O Of O 13 O documented O fractures B-Disease , O 3 O occurred O after O risperidone B-Chemical and O SSRIs O were O started O , O and O none O occurred O in O patients O with O hyperprolactinemia B-Disease . O CONCLUSIONS O : O This O is O the O first O study O to O link O risperidone B-Chemical - O induced O hyperprolactinemia B-Disease and O SSRI O treatment O to O lower O BMD O in O children O and O adolescents O . O Future O research O should O evaluate O the O longitudinal O course O of O this O adverse O event O to O determine O its O temporal O stability O and O whether O a O higher O fracture O rate O ensues O . O Fear O - O potentiated O startle B-Disease , O but O not O light O - O enhanced O startle B-Disease , O is O enhanced O by O anxiogenic O drugs O . O RATIONALE O AND O OBJECTIVES O : O The O light O - O enhanced O startle B-Disease paradigm O ( O LES O ) O is O suggested O to O model O anxiety B-Disease , O because O of O the O non O - O specific O cue O and O the O long O - O term O effect O . O In O contrast O , O the O fear O - O potentiated O startle B-Disease ( O FPS O ) O is O suggested O to O model O conditioned O fear O . O However O , O the O pharmacological O profiles O of O these O two O paradigms O are O very O similar O . O The O present O study O investigated O the O effects O of O putative O anxiogenic O drugs O on O LES O and O FPS O and O aimed O at O determining O the O sensitivity O of O LES O for O anxiogenic O drugs O and O to O potentially O showing O a O pharmacological O differentiation O between O these O two O paradigms O . O METHODS O : O Male O Wistar O rats O received O each O dose O of O the O alpha O ( O 2 O ) O - O adrenoceptor O antagonist O yohimbine B-Chemical ( O 0 O . O 25 O - O 1 O . O 0mg O / O kg O ) O , O the O 5 B-Chemical - I-Chemical HT I-Chemical ( O 2C O ) O receptor O agonist O m B-Chemical - I-Chemical chlorophenylpiperazine I-Chemical ( O mCPP B-Chemical , O 0 O . O 5 O - O 2 O . O 0mg O / O kg O ) O or O the O GABA B-Chemical ( O A O ) O inverse O receptor O agonist O pentylenetetrazole B-Chemical ( O PTZ B-Chemical , O 3 O - O 30mg O / O kg O ) O and O were O subsequently O tested O in O either O LES O or O FPS O . O RESULTS O : O None O of O the O drugs O enhanced O LES O , O whereas O mCPP B-Chemical increased O percentage O FPS O and O yohimbine B-Chemical increased O absolute O FPS O values O . O Furthermore O , O yohimbine B-Chemical increased O baseline O startle B-Disease amplitude O in O the O LES O , O while O mCPP B-Chemical suppressed O baseline O startle B-Disease in O both O the O LES O and O FPS O and O PTZ B-Chemical suppressed O baseline O startle B-Disease in O the O FPS O . O CONCLUSIONS O : O In O contrast O to O findings O in O the O FPS O paradigm O , O none O of O the O drugs O were O able O to O exacerbate O the O LES O response O . O Thus O , O a O clear O pharmacological O differentiation O was O found O between O LES O and O FPS O . O Rosaceiform O dermatitis B-Disease associated O with O topical O tacrolimus B-Chemical treatment O . O We O describe O herein O 3 O patients O who O developed O rosacea B-Disease - O like O dermatitis B-Disease eruptions B-Disease while O using O 0 O . O 03 O % O or O 0 O . O 1 O % O tacrolimus B-Chemical ointment O for O facial B-Disease dermatitis I-Disease . O Skin O biopsy O specimens O showed O telangiectasia B-Disease and O noncaseating O epithelioid O granulomatous O tissue O formation O in O the O papillary O to O mid O dermis O . O Continuous O topical O use O of O immunomodulators O such O as O tacrolimus B-Chemical or O pimecrolimus B-Chemical should O be O regarded O as O a O potential O cause O of O rosaceiform O dermatitis B-Disease , O although O many O cases O have O not O been O reported O . O Coenzyme B-Chemical Q10 I-Chemical treatment O ameliorates O acute O cisplatin B-Chemical nephrotoxicity B-Disease in O mice O . O The O nephroprotective O effect O of O coenzyme B-Chemical Q10 I-Chemical was O investigated O in O mice O with O acute B-Disease renal I-Disease injury I-Disease induced O by O a O single O i O . O p O . O injection O of O cisplatin B-Chemical ( O 5 O mg O / O kg O ) O . O Coenzyme B-Chemical Q10 I-Chemical treatment O ( O 10 O mg O / O kg O / O day O , O i O . O p O . O ) O was O applied O for O 6 O consecutive O days O , O starting O 1 O day O before O cisplatin B-Chemical administration O . O Coenzyme B-Chemical Q10 I-Chemical significantly O reduced O blood B-Chemical urea I-Chemical nitrogen I-Chemical and O serum O creatinine B-Chemical levels O which O were O increased O by O cisplatin B-Chemical . O Coenzyme B-Chemical Q10 I-Chemical significantly O compensated O deficits O in O the O antioxidant O defense O mechanisms O ( O reduced B-Chemical glutathione I-Chemical level O and O superoxide B-Chemical dismutase O activity O ) O , O suppressed O lipid O peroxidation O , O decreased O the O elevations O of O tumor B-Disease necrosis B-Disease factor O - O alpha O , O nitric B-Chemical oxide I-Chemical and O platinum B-Chemical ion O concentration O , O and O attenuated O the O reductions O of O selenium B-Chemical and O zinc B-Chemical ions O in O renal O tissue O resulted O from O cisplatin B-Chemical administration O . O Also O , O histopathological O renal B-Disease tissue I-Disease damage I-Disease mediated O by O cisplatin B-Chemical was O ameliorated O by O coenzyme B-Chemical Q10 I-Chemical treatment O . O Immunohistochemical O analysis O revealed O that O coenzyme B-Chemical Q10 I-Chemical significantly O decreased O the O cisplatin B-Chemical - O induced O overexpression O of O inducible O nitric B-Chemical oxide I-Chemical synthase O , O nuclear O factor O - O kappaB O , O caspase O - O 3 O and O p53 O in O renal O tissue O . O It O was O concluded O that O coenzyme B-Chemical Q10 I-Chemical represents O a O potential O therapeutic O option O to O protect O against O acute O cisplatin B-Chemical nephrotoxicity B-Disease commonly O encountered O in O clinical O practice O . O Reversible O cholestasis B-Disease with O bile B-Disease duct I-Disease injury I-Disease following O azathioprine B-Chemical therapy O . O A O case O report O . O A O 67 O - O year O - O old O patient O , O with O primary O polymyositis B-Disease and O without O previous O evidence O of O liver B-Disease disease I-Disease , O developed O clinical O and O biochemical O features O of O severe O cholestasis B-Disease 3 O months O after O initiation O of O azathioprine B-Chemical therapy O . O Liver O biopsy O showed O cholestasis B-Disease with O both O cytological O and O architectural O alterations O of O interlobular O bile O ducts O . O Azathioprine B-Chemical withdrawal O resulted O after O 7 O weeks O in O the O resolution O of O clinical O and O biochemical O abnormalities O . O It O is O believed O that O this O is O the O first O reported O case O of O reversible O azathioprine B-Chemical - O induced O cholestasis B-Disease associated O with O histological O evidence O of O bile B-Disease duct I-Disease injury I-Disease . O Dopamine B-Chemical is O not O essential O for O the O development O of O methamphetamine B-Chemical - O induced O neurotoxicity B-Disease . O It O is O widely O believed O that O dopamine B-Chemical ( O DA B-Chemical ) O mediates O methamphetamine B-Chemical ( O METH B-Chemical ) O - O induced O toxicity B-Disease to O brain O dopaminergic O neurons O , O because O drugs O that O interfere O with O DA B-Chemical neurotransmission O decrease O toxicity B-Disease , O whereas O drugs O that O increase O DA B-Chemical neurotransmission O enhance O toxicity B-Disease . O However O , O temperature O effects O of O drugs O that O have O been O used O to O manipulate O brain O DA B-Chemical neurotransmission O confound O interpretation O of O the O data O . O Here O we O show O that O the O recently O reported O ability O of O L B-Chemical - I-Chemical dihydroxyphenylalanine I-Chemical to O reverse O the O protective O effect O of O alpha B-Chemical - I-Chemical methyl I-Chemical - I-Chemical para I-Chemical - I-Chemical tyrosine I-Chemical on O METH B-Chemical - O induced O DA B-Chemical neurotoxicity B-Disease is O also O confounded O by O drug O effects O on O body O temperature O . O Further O , O we O show O that O mice O genetically O engineered O to O be O deficient O in O brain O DA B-Chemical develop O METH B-Chemical neurotoxicity B-Disease , O as O long O as O the O thermic O effects O of O METH B-Chemical are O preserved O . O In O addition O , O we O demonstrate O that O mice O genetically O engineered O to O have O unilateral O brain O DA B-Chemical deficits O develop O METH B-Chemical - O induced O dopaminergic B-Disease deficits I-Disease that O are O of O comparable O magnitude O on O both O sides O of O the O brain O . O Taken O together O , O these O findings O demonstrate O that O DA B-Chemical is O not O essential O for O the O development O of O METH B-Chemical - O induced O dopaminergic O neurotoxicity B-Disease and O suggest O that O mechanisms O independent O of O DA B-Chemical warrant O more O intense O investigation O . O Swallowing O - O induced O atrial B-Disease tachyarrhythmia I-Disease triggered O by O salbutamol B-Chemical : O case O report O and O review O of O the O literature O . O CASE O : O A O 49 O - O year O - O old O patient O experienced O chest O discomfort O while O swallowing O . O On O electrocardiogram O , O episodes O of O atrial B-Disease tachyarrhythmia I-Disease were O recorded O immediately O after O swallowing O ; O 24 O - O hour O Holter O monitoring O recorded O several O events O . O The O arrhythmia B-Disease resolved O after O therapy O with O atenolol B-Chemical , O but O recurred O a O year O later O . O The O patient O noticed O that O before O these O episodes O he O had O been O using O an O inhalator O of O salbutamol B-Chemical . O After O stopping O the O beta O - O agonist O , O and O after O a O week O with O the O atenolol B-Chemical , O the O arrhythmia B-Disease disappeared O . O DISCUSSION O : O Swallowing O - O induced O atrial B-Disease tachyarrhythmia I-Disease ( O SIAT B-Disease ) O is O a O rare O phenomenon O . O Fewer O than O 50 O cases O of O SIAT B-Disease have O been O described O in O the O literature O . O This O article O summarizes O all O the O cases O published O , O creating O a O comprehensive O review O of O the O current O knowledge O and O approach O to O SIAT B-Disease . O It O discusses O demographics O , O clinical O characteristics O and O types O of O arrhythmia B-Disease , O postulated O mechanisms O of O SIAT B-Disease , O and O different O treatment O possibilities O such O as O medications O , O surgery O , O and O radiofrequency O catheter O ablation O ( O RFCA O ) O . O CONCLUSION O : O Salbutamol B-Chemical is O presented O here O as O a O possible O trigger O for O SIAT B-Disease . O Although O it O is O difficult O to O define O causality O in O a O case O report O , O it O is O logical O to O think O that O a O beta O - O agonist O like O salbutamol B-Chemical ( O known O to O induce O tachycardia B-Disease ) O may O be O the O trigger O of O adrenergic O reflexes O originating O in O the O esophagus O while O swallowing O and O that O a O beta O - O blocker O such O as O atenolol B-Chemical ( O that O blocks O the O adrenergic O activity O ) O may O relieve O it O . O The O ability O of O insulin O treatment O to O reverse O or O prevent O the O changes O in O urinary O bladder O function O caused O by O streptozotocin B-Chemical - O induced O diabetes B-Disease mellitus I-Disease . O 1 O . O The O effects O of O insulin O treatment O on O in O vivo O and O in O vitro O urinary O bladder O function O in O streptozotocin B-Chemical - O diabetic B-Disease rats O were O investigated O .

O Diabetes B-Disease of O 2 O months O duration O resulted O in O decreases O in O body O weight O and O increases O in O fluid O consumption O , O urine O volume O , O frequency O of O micturition O , O and O average O volume O per O micturition O ; O effects O which O were O prevented O by O insulin O treatment O . O 3 O . O Insulin O treatment O also O prevented O the O increases O in O contractile O responses O of O bladder O body O strips O from O diabetic B-Disease rats O to O nerve O stimulation O , O ATP B-Chemical , O and O bethanechol B-Chemical . O 4 O . O Diabetes B-Disease of O 4 O months O duration O also O resulted O in O decreases O in O body O weight O , O and O increases O in O fluid O consumption O , O urine O volume O , O frequency O of O micturition O , O and O average O volume O per O micturition O , O effects O which O were O reversed O by O insulin O treatment O for O the O final O 2 O months O of O the O study O . O 5 O . O Insulin O treatment O reversed O the O increases O in O contractile O responses O of O bladder O body O strips O from O diabetic B-Disease rats O to O nerve O stimulation O , O ATP B-Chemical , O and O bethanechol B-Chemical . O 6 O . O The O data O indicate O that O the O effects O of O streptozotocin B-Chemical - O induced O diabetes B-Disease on O urinary O bladder O function O are O both O prevented O and O reversed O by O insulin O treatment O . O Glutamatergic O neurotransmission O mediated O by O NMDA B-Chemical receptors O in O the O inferior O colliculus O can O modulate O haloperidol B-Chemical - O induced O catalepsy B-Disease . O The O inferior O colliculus O ( O IC O ) O is O primarily O involved O in O the O processing O of O auditory O information O , O but O it O is O distinguished O from O other O auditory O nuclei O in O the O brainstem O by O its O connections O with O structures O of O the O motor O system O . O Functional O evidence O relating O the O IC O to O motor O behavior O derives O from O experiments O showing O that O activation O of O the O IC O by O electrical O stimulation O or O excitatory O amino B-Chemical acid I-Chemical microinjection O causes O freezing O , O escape O - O like O behavior O , O and O immobility O . O However O , O the O nature O of O this O immobility O is O still O unclear O . O The O present O study O examined O the O influence O of O excitatory O amino B-Chemical acid I-Chemical - O mediated O mechanisms O in O the O IC O on O the O catalepsy B-Disease induced O by O the O dopamine B-Chemical receptor O blocker O haloperidol B-Chemical administered O systemically O ( O 1 O or O 0 O . O 5 O mg O / O kg O ) O in O rats O . O Haloperidol B-Chemical - O induced O catalepsy B-Disease was O challenged O with O prior O intracollicular O microinjections O of O glutamate B-Chemical NMDA B-Chemical receptor O antagonists O , O MK B-Chemical - I-Chemical 801 I-Chemical ( O 15 O or O 30 O mmol O / O 0 O . O 5 O microl O ) O and O AP7 B-Chemical ( O 10 O or O 20 O nmol O / O 0 O . O 5 O microl O ) O , O or O of O the O NMDA B-Chemical receptor O agonist O N B-Chemical - I-Chemical methyl I-Chemical - I-Chemical d I-Chemical - I-Chemical aspartate I-Chemical ( O NMDA B-Chemical , O 20 O or O 30 O nmol O / O 0 O .

O The O results O showed O that O intracollicular O microinjection O of O MK B-Chemical - I-Chemical 801 I-Chemical and O AP7 B-Chemical previous O to O systemic O injections O of O haloperidol B-Chemical significantly O attenuated O the O catalepsy B-Disease , O as O indicated O by O a O reduced O latency O to O step O down O from O a O horizontal O bar O . O Accordingly O , O intracollicular O microinjection O of O NMDA B-Chemical increased O the O latency O to O step O down O the O bar O . O These O findings O suggest O that O glutamate B-Chemical - O mediated O mechanisms O in O the O neural O circuits O at O the O IC O level O influence O haloperidol B-Chemical - O induced O catalepsy B-Disease and O participate O in O the O regulation O of O motor O activity O . O Severe O congestive B-Disease heart I-Disease failure I-Disease patient O on O amiodarone B-Chemical presenting O with O myxedemic B-Disease coma I-Disease : O a O case O report O . O This O is O a O case O report O of O myxedema B-Disease coma I-Disease secondary O to O amiodarone B-Chemical - O induced O hypothyroidism B-Disease in O a O patient O with O severe O congestive B-Disease heart I-Disease failure I-Disease ( O CHF B-Disease ) O . O To O our O knowledge O and O after O reviewing O the O literature O there O is O one O case O report O of O myxedema B-Disease coma I-Disease during O long O term O amiodarone B-Chemical therapy O . O Myxedema B-Disease coma I-Disease is O a O life O threatening O condition O that O carries O a O mortality O reaching O as O high O as O 20 O % O with O treatment O . O The O condition O is O treated O with O intravenous O thyroxine B-Chemical ( O T4 B-Chemical ) O or O intravenous O tri B-Chemical - I-Chemical iodo I-Chemical - I-Chemical thyronine I-Chemical ( O T3 B-Chemical ) O . O Patients O with O CHF B-Disease on O amiodarone B-Chemical may O suffer O serious O morbidity O and O mortality O from O hypothyroidism B-Disease , O and O thus O may O deserve O closer O follow O up O for O thyroid O stimulating O hormone O ( O TSH O ) O levels O . O This O case O report O carries O an O important O clinical O application O given O the O frequent O usage O of O amiodarone B-Chemical among O CHF B-Disease patients O . O The O myriad O clinical O presentation O of O myxedema B-Disease coma I-Disease and O its O serious O morbidity O and O mortality O stresses O the O need O to O suspect O this O clinical O syndrome O among O CHF B-Disease patients O presenting O with O hypotension B-Disease , O weakness B-Disease or O other O unexplained O symptoms O .

O The O symptoms O of O methamphetamine B-Chemical ( O METH B-Chemical ) O - O induced O psychosis B-Disease are O similar O to O those O of O paranoid B-Disease type I-Disease schizophrenia I-Disease . O Therefore O , O we O conducted O an O analysis O of O the O association O of O the O 5 B-Chemical - I-Chemical HT6 I-Chemical gene O ( O HTR6 O ) O with O METH B-Chemical - O induced O psychosis B-Disease . O METHOD O : O Using O five O tagging O SNPs O ( O rs6693503 O , O rs1805054 O , O rs4912138 O , O rs3790757 O and O rs9659997 O ) O , O we O conducted O a O genetic O association O analysis O of O case O - O control O samples O ( O 197 O METH B-Chemical - O induced O psychosis B-Disease patients O and O 337 O controls O ) O in O the O Japanese O population O .

O During O the O scanning O period O , O subjects O performed O continuous O overt O verbal O fluency O tasks O ( O phonological O , O lexical O and O semantic O ) O . O Ketamine B-Chemical - O induced O psychopathological O symptoms O were O assessed O with O the O Positive O and O Negative O Syndrome O Scale O ( O PANSS O ) O . O Ketamine B-Chemical elicited O psychosis B-Disease like O psychopathology O . O Post O - O hoc O t O - O tests O revealed O significant O differences O between O placebo O and O ketamine B-Chemical for O the O amounts O of O words O generated O during O lexical O and O semantic O verbal O fluency O , O while O the O phonological O domain O remained O unaffected O . O Ketamine B-Chemical led O to O enhanced O cortical O activations O in O supramarginal O and O frontal O brain O regions O for O phonological O and O lexical O verbal O fluency O , O but O not O for O semantic O verbal O fluency O . O Ketamine B-Chemical induces O activation O changes O in O healthy O subjects O similar O to O those O observed O in O patients O with O schizophrenia B-Disease , O particularly O in O frontal O and O temporal O brain O regions O .

O Long O - O term O prognosis O for O transplant O - O free O survivors O of O paracetamol B-Chemical - O induced O acute B-Disease liver I-Disease failure I-Disease . O BACKGROUND O : O The O prognosis O for O transplant O - O free O survivors O of O paracetamol B-Chemical - O induced O acute B-Disease liver I-Disease failure I-Disease remains O unknown O . O AIM O : O To O examine O whether O paracetamol B-Chemical - O induced O acute B-Disease liver I-Disease failure I-Disease increases O long O - O term O mortality O . O METHODS O : O We O followed O up O all O transplant O - O free O survivors O of O paracetamol B-Chemical - O induced O acute B-Disease liver I-Disease injury I-Disease , O hospitalized O in O a O Danish O national O referral O centre O during O 1984 O - O 2004 O . O We O compared O age O - O specific O mortality O rates O from O 1 O year O post O - O discharge O through O 2008 O between O those O in O whom O the O liver B-Disease injury I-Disease led O to O an O acute B-Disease liver I-Disease failure I-Disease and O those O in O whom O it O did O not O . O RESULTS O : O We O included O 641 O patients O . O On O average O , O age O - O specific O mortality O rates O were O slightly O higher O for O the O 101 O patients O whose O paracetamol B-Chemical - O induced O liver B-Disease injury I-Disease had O caused O an O acute B-Disease liver I-Disease failure I-Disease ( O adjusted O mortality O rate O ratio O = O 1 O .

O These O observations O speak O against O long O - O term O effects O of O acute B-Disease liver I-Disease failure I-Disease . O More O likely O , O the O elevated O mortality O rate O ratio O resulted O from O incomplete O adjustment O for O the O greater O prevalence O of O substance B-Disease abuse I-Disease among O survivors O of O acute B-Disease liver I-Disease failure I-Disease . O CONCLUSIONS O : O Paracetamol B-Chemical - O induced O acute B-Disease liver I-Disease failure I-Disease did O not O affect O long O - O term O mortality O .

O Effects O of O the O hippocampal O deep O brain O stimulation O on O cortical O epileptic B-Disease discharges O in O penicillin B-Chemical - O induced O epilepsy B-Disease model O in O rats O . O AIM O : O Experimental O and O clinical O studies O have O revealed O that O hippocampal O DBS O can O control O epileptic B-Disease activity O , O but O the O mechanism O of O action O is O obscure O and O optimal O stimulation O parameters O are O not O clearly O defined O . O The O aim O was O to O evaluate O the O effects O of O high O frequency O hippocampal O stimulation O on O cortical O epileptic B-Disease activity O in O penicillin B-Chemical - O induced O epilepsy B-Disease model O . O MATERIAL O AND O METHODS O : O Twenty O - O five O Sprague O - O Dawley O rats O were O implanted O DBS O electrodes O . O In O group O - O 1 O ( O n O = O 10 O ) O hippocampal O DBS O was O off O and O in O the O group O - O 2 O ( O n O = O 10 O ) O hippocampal O DBS O was O on O ( O 185 O Hz O , O 0 O .

O DESIGN O : O The O medical O records O of O 206 O dogs O that O were O treated O with O CCNU B-Chemical at O the O Melbourne O Veterinary O Specialist O Centre O between O February O 2002 O and O December O 2007 O were O retrospectively O evaluated O . O RESULTS O : O Of O the O 206 O dogs O treated O with O CCNU B-Chemical , O 185 O met O the O inclusion O criteria O for O at O least O one O class O of O toxicity B-Disease . O CCNU B-Chemical was O used O most O commonly O in O the O treatment O of O lymphoma B-Disease , O mast B-Disease cell I-Disease tumour I-Disease , O brain B-Disease tumour I-Disease , O histiocytic B-Disease tumours I-Disease and O epitheliotropic B-Disease lymphoma I-Disease . O Throughout O treatment O , O 56 O . O 9 O % O of O dogs O experienced O neutropenia B-Disease , O 34 O . O 2 O % O experienced O anaemia B-Disease and O 14 O . O 2 O % O experienced O thrombocytopenia B-Disease . O Gastrointestinal B-Disease toxicosis I-Disease was O detected O in O 37 O . O 8 O % O of O dogs O , O the O most O common O sign O of O which O was O vomiting B-Disease ( O 24 O . O 3 O % O ) O .

O 8 O % O of O dogs O , O respectively O . O The O incidence O of O hepatic B-Disease failure I-Disease was O 1 O . O 2 O % O . O CONCLUSIONS O : O CCNU B-Chemical - O associated O toxicity B-Disease in O dogs O is O common O , O but O is O usually O not O life O threatening O . O Central O vein B-Disease thrombosis I-Disease and O topical O dipivalyl B-Chemical epinephrine I-Chemical . O A O report O is O given O on O an O 83 O - O year O - O old O female O who O acquired O central O vein B-Disease thrombosis I-Disease in O her O seeing O eye O one O day O after O having O started O topical O medication O with O dipivalyl B-Chemical epinephrine I-Chemical for O advanced O glaucoma B-Disease discovered O in O the O other O eye O . O From O present O knowledge O about O the O effects O of O adrenergic O eye O drops O on O ocular O blood O circulation O , O it O is O difficult O to O suggest O an O association O between O the O two O events O , O which O may O be O coincidental O only O . O Benzylacyclouridine B-Chemical reverses O azidothymidine B-Chemical - O induced O marrow B-Disease suppression I-Disease without O impairment O of O anti O - O human O immunodeficiency B-Disease virus O activity O . O Increased O extracellular O concentrations O of O uridine B-Chemical ( O Urd B-Chemical ) O have O been O reported O to O reduce O , O in O vitro O , O azidothymidine B-Chemical ( O AZT B-Chemical ) O - O induced O inhibition O of O human O granulocyte O - O macrophage O progenitor O cells O without O impairment O of O its O antihuman O immunodeficiency B-Disease virus O ( O HIV O ) O activity O . O Because O of O the O clinical O toxicities B-Disease associated O with O chronic O Urd B-Chemical administration O , O the O ability O of O benzylacyclouridine B-Chemical ( O BAU B-Chemical ) O to O effect O , O in O vivo O , O AZT B-Chemical - O induced O anemia B-Disease and O leukopenia B-Disease was O assessed O . O This O agent O inhibits O Urd B-Chemical catabolism O and O , O in O vivo O , O increases O the O plasma O concentration O of O Urd B-Chemical in O a O dose O - O dependent O manner O , O without O Urd B-Chemical - O related O toxicity B-Disease . O In O mice O rendered O anemic B-Disease and O leukopenic B-Disease by O the O administration O of O AZT B-Chemical for O 28 O days O in O drinking O water O ( O 1 O . O 5 O mg O / O mL O ) O , O the O continued O administration O of O AZT B-Chemical plus O daily O BAU B-Chemical ( O 300 O mg O / O kg O , O orally O ) O partially O reversed O AZT B-Chemical - O induced O anemia B-Disease and O leukopenia B-Disease ( O P O less O than O . O 05 O ) O , O increased O peripheral O reticulocytes O ( O to O 4 O . O 9 O % O , O P O less O than O . O 01 O ) O , O increased O cellularity O in O the O marrow O , O and O improved O megaloblastosis B-Disease . O When O coadministered O with O AZT B-Chemical from O the O onset O of O drug O administration O , O BAU B-Chemical reduced O AZT B-Chemical - O induced O marrow B-Disease toxicity I-Disease . O In O vitro O , O at O a O concentration O of O 100 O mumol O / O L O , O BAU B-Chemical possesses O minimal O anti O - O HIV O activity O and O has O no O effect O on O the O ability O of O AZT B-Chemical to O reverse O the O HIV O - O induced O cytopathic O effect O in O MT4 O cells O . O The O clinical O and O biochemical O implications O of O these O findings O are O discussed O . O Lethal O anuria B-Disease complicating O high O dose O ifosfamide B-Chemical chemotherapy O in O a O breast B-Disease cancer I-Disease patient O with O an O impaired B-Disease renal I-Disease function I-Disease . O A O sixty O - O year O - O old O woman O with O advanced O breast B-Disease cancer I-Disease , O previously O treated O with O cisplatin B-Chemical , O developed O an O irreversible O lethal O renal B-Disease failure I-Disease with O anuria B-Disease , O the O day O after O 5 O g O / O m2 O bolus O ifosfamide B-Chemical . O Postrenal B-Disease failure I-Disease was O excluded O by O echography O . O A O prerenal O component O could O have O contributed O to O renal B-Disease failure I-Disease because O of O a O transient O hypotension B-Disease , O due O to O an O increasing O ascitis O , O occurring O just O before O anuria B-Disease . O However O , O correction O of O the O hemodynamic O parameters O did O not O improve O renal O function O . O Ifosfamide B-Chemical is O a O known O nephrotoxic B-Disease drug O with O demonstrated O tubulopathies B-Disease . O We O strongly O suspect O that O this O lethal O anuria B-Disease was O mainly O due O to O ifosfamide B-Chemical , O occurring O in O a O patient O having O received O previous O cisplatin B-Chemical chemotherapy O and O with O poor O kidney O perfusion O due O to O transient O hypotension B-Disease . O We O recommend O careful O use O of O ifosfamide B-Chemical in O patients O pretreated O with O nephrotoxic B-Disease chemotherapy O and O inadequate O renal O perfusion O . O Nociceptive O effects O induced O by O intrathecal O administration O of O prostaglandin B-Chemical D2 I-Chemical , I-Chemical E2 I-Chemical , I-Chemical or I-Chemical F2 I-Chemical alpha I-Chemical to O conscious O mice O . O The O effects O of O intrathecal O administration O of O prostaglandins B-Chemical on O pain B-Disease responses O in O conscious O mice O were O evaluated O by O using O hot O plate O and O acetic B-Chemical acid I-Chemical writhing O tests O . O Prostaglandin B-Chemical D2 I-Chemical ( O 0 O . O 5 O - O 3 O ng O / O mouse O ) O had O a O hyperalgesic B-Disease action O on O the O response O to O a O hot O plate O during O a O 3 O - O 60 O min O period O after O injection O . O Prostaglandin B-Chemical E2 I-Chemical showed O a O hyperalgesic B-Disease effect O at O doses O of O 1 O pg B-Chemical to O 10 O ng O / O mouse O , O but O the O effect O lasted O shorter O ( O 3 O - O 30 O min O ) O than O that O of O prostaglandin B-Chemical D2 I-Chemical . O Similar O results O were O obtained O by O acetic B-Chemical acid I-Chemical writhing O tests O . O The O hyperalgesic B-Disease effect O of O prostaglandin B-Chemical D2 I-Chemical was O blocked O by O simultaneous O injection O of O a O substance O P O antagonist O ( O greater O than O or O equal O to O 100 O ng O ) O but O not O by O AH6809 B-Chemical , O a O prostanoid O EP1 O - O receptor O antagonist O . O Conversely O , O prostaglandin B-Chemical E2 I-Chemical - O induced O hyperalgesia B-Disease was O blocked O by O AH6809 B-Chemical ( O greater O than O or O equal O to O 500 O ng O ) O but O not O by O the O substance O P O antagonist O . O Prostaglandin B-Chemical F2 I-Chemical alpha I-Chemical had O little O effect O on O pain B-Disease responses O . O These O results O demonstrate O that O both O prostaglandin B-Chemical D2 I-Chemical and O prostaglandin B-Chemical E2 I-Chemical exert O hyperalgesia B-Disease in O the O spinal O cord O , O but O in O different O ways O . O D B-Chemical - I-Chemical penicillamine I-Chemical in O the O treatment O of O localized B-Disease scleroderma I-Disease . O Localized B-Disease scleroderma I-Disease has O no O recognized O internal O organ O involvement O but O may O be O disfiguring O and O disabling O when O the O cutaneous O lesions O are O extensive O or O affect O children O . O There O is O no O accepted O or O proven O treatment O for O localized B-Disease scleroderma I-Disease . O Case O reports O of O 11 O patients O with O severe O , O extensive O localized B-Disease scleroderma I-Disease who O were O treated O with O D B-Chemical - I-Chemical penicillamine I-Chemical are O summarized O in O this O article O . O This O drug O was O judged O to O have O a O favorable O effect O on O the O disease O course O in O 7 O ( O 64 O % O ) O of O 11 O patients O . O Improvement O began O within O 3 O to O 6 O months O and O consisted O of O cessation O of O active O cutaneous O lesions O in O all O 7 O patients O , O skin O softening O in O 5 O , O and O more O normal O growth O of O the O affected O limb O in O 2 O of O 3 O children O . O Joint O stiffness O and O contractures B-Disease also O improved O . O The O dose O of O D B-Chemical - I-Chemical penicillamine I-Chemical associated O with O a O favorable O response O was O as O low O as O 2 O to O 5 O mg O / O kg O per O day O given O over O a O period O ranging O from O 15 O to O 53 O months O . O D B-Chemical - I-Chemical Penicillamine I-Chemical caused O nephrotic B-Disease syndrome I-Disease in O 1 O patient O and O milder O reversible O proteinuria B-Disease in O 3 O other O patients O ; O none O developed O renal B-Disease insufficiency I-Disease . O These O data O suggest O that O D B-Chemical - I-Chemical penicillamine I-Chemical may O be O effective O in O severe O cases O of O localized B-Disease scleroderma I-Disease . O Cerebral B-Disease sinus I-Disease thrombosis I-Disease as O a O potential O hazard O of O antifibrinolytic O treatment O in O menorrhagia B-Disease . O We O describe O a O 42 O - O year O - O old O woman O who O developed O superior O sagittal B-Disease and I-Disease left I-Disease transverse I-Disease sinus I-Disease thrombosis I-Disease associated O with O prolonged O epsilon B-Chemical - I-Chemical aminocaproic I-Chemical acid I-Chemical therapy O for O menorrhagia B-Disease . O This O antifibrinolytic O agent O has O been O used O in O women O with O menorrhagia B-Disease to O promote O clotting O and O reduce O blood B-Disease loss I-Disease . O Although O increased O risk O of O thromboembolic B-Disease disease I-Disease has O been O reported O during O treatment O with O epsilon B-Chemical - I-Chemical aminocaproic I-Chemical acid I-Chemical , O cerebral B-Disease sinus I-Disease thrombosis I-Disease has O not O been O previously O described O . O Careful O use O of O epsilon B-Chemical - I-Chemical aminocaproic I-Chemical acid I-Chemical therapy O is O recommended O . O Seizure B-Disease activity O with O imipenem B-Chemical therapy O : O incidence O and O risk O factors O . O Two O elderly O patients O with O a O history O of O either O cerebral B-Disease vascular I-Disease accident I-Disease ( O CVA B-Disease ) O or O head B-Disease trauma I-Disease and O no O evidence O of O renal B-Disease disease I-Disease developed O seizures B-Disease while O receiving O maximum O doses O of O imipenem B-Chemical / I-Chemical cilastatin I-Chemical . O Neither O patient O had O reported O previous O seizures B-Disease or O seizure B-Disease - O like O activity O nor O was O receiving O anticonvulsant O agents O . O All O seizures B-Disease were O controlled O with O therapeutic O doses O of O phenytoin B-Chemical . O Both O patients O had O received O maximum O doses O of O other O beta B-Chemical - I-Chemical lactam I-Chemical antibiotics O without O evidence O of O seizure B-Disease activity O . O Midline O B3 O serotonin B-Chemical nerves O in O rat O medulla O are O involved O in O hypotensive B-Disease effect O of O methyldopa B-Chemical . O Previous O experiments O in O this O laboratory O have O shown O that O microinjection O of O methyldopa B-Chemical onto O the O ventrolateral O cells O of O the O B3 O serotonin B-Chemical neurons O in O the O medulla O elicits O a O hypotensive B-Disease response O mediated O by O a O projection O descending O into O the O spinal O cord O . O The O present O experiments O were O designed O to O investigate O the O role O of O the O midline O cells O of O the O B3 O serotonin B-Chemical neurons O in O the O medulla O , O coinciding O with O the O raphe O magnus O . O In O spontaneously O hypertensive B-Disease , O stroke B-Disease - O prone O rats O , O microinjection O of O methyldopa B-Chemical into O the O area O of O the O midline O B3 O serotonin B-Chemical cell O group O in O the O ventral O medulla O caused O a O potent O hypotension B-Disease of O 30 O - O 40 O mm O Hg O , O which O was O maximal O 2 O - O 3 O h O after O administration O and O was O abolished O by O the O serotonin B-Chemical neurotoxin O 5 B-Chemical , I-Chemical 7 I-Chemical - I-Chemical dihydroxytryptamine I-Chemical ( O 5 B-Chemical , I-Chemical 7 I-Chemical - I-Chemical DHT I-Chemical ) O injected O intracerebroventricularly O . O However O , O intraspinal O injection O of O 5 B-Chemical , I-Chemical 7 I-Chemical - I-Chemical DHT I-Chemical to O produce O a O more O selective O lesion O of O only O descending O serotonin B-Chemical projections O in O the O spinal O cord O did O not O affect O this O hypotension B-Disease .

O It O is O concluded O therefore O that O , O unlike O the O ventrolateral O B3 O cells O which O mediate O a O methyldopa B-Chemical - O induced O hypotension B-Disease via O descending O projections O , O the O midline O serotonin B-Chemical B3 O cells O in O the O medulla O contribute O to O the O hypotensive B-Disease action O of O methyldopa B-Chemical , O either O by O way O of O an O ascending O projection O which O does O not O pass O through O the O median O forebrain O bundle O , O or O through O a O projection O restricted O to O the O caudal O brainstem O .

O These O data O suggest O naloxone B-Chemical reverses O respiratory B-Disease paralysis I-Disease produced O by O thiopental B-Chemical and O involves O GABA B-Chemical in O its O action O . O Diazepam B-Chemical facilitates O reflex O bradycardia B-Disease in O conscious O rats O . O The O effects O of O diazepam B-Chemical on O cardiovascular O function O were O assessed O in O conscious O rats O . O Intravenous O administration O of O diazepam B-Chemical ( O 1 O - O 30 O mg O kg O - O 1 O ) O produced O a O dose O - O dependent O decrease O in O both O the O mean O arterial O pressure O and O the O heart O rate O .

O Intravenous O pretreatment O of O the O rats O with O diazepam B-Chemical , O although O causing O no O change O in O the O adrenaline B-Chemical - O induced O pressor O effect O , O did O enhance O the O adrenaline B-Chemical - O induced O reflex O bradycardia B-Disease . O However O , O the O diazepam B-Chemical enhancement O of O adrenaline B-Chemical - O induced O reflex O bradycardia B-Disease was O antagonized O by O pretreatment O of O rats O with O an O intravenous O dose O of O picrotoxin B-Chemical ( O an O agent O blocks O chloride B-Chemical channels O by O binding O to O sites O associated O with O the O benzodiazepine B-Chemical - O GABA B-Chemical - O chloride B-Chemical channel O macromolecular O complex O ) O . O The O data O indicate O that O diazepam B-Chemical acts O through O the O benzodiazepine B-Chemical - O GABA B-Chemical - O chloride B-Chemical channel O macromolecular O complex O within O the O central O nervous O system O to O facilitate O reflex O bradycardia B-Disease mediated O through O baroreceptor O reflexes O in O response O to O an O acute O increase O in O arterial O pressure O . O Initial O potassium B-Chemical loss O and O hypokalaemia B-Disease during O chlorthalidone B-Chemical administration O in O patients O with O essential O hypertension B-Disease : O the O influence O of O dietary O sodium B-Chemical restriction O . O To O investigate O the O initial O potassium B-Chemical loss O and O development O of O hypokalaemia B-Disease during O the O administration O of O an O oral O diuretic O , O metabolic O balance O studies O were O performed O in O ten O patients O with O essential O hypertension B-Disease who O had O shown O hypokalaemia B-Disease under O prior O oral O diuretic O treatment O . O Chlorthalidone B-Chemical ( O 50 O mg O daily O ) O was O given O for O 14 O days O . O Six O patients O received O a O normal O - O sodium B-Chemical diet O and O four O a O low O - O sodium B-Chemical ( O 17 O mmol O / O day O ) O diet O . O All O patients O had O a O normal O initial O total O body O potassium B-Chemical ( O 40K O ) O . O The O electrolyte O balances O , O weight O , O bromide O space O , O plasma O renin O activity O , O and O aldosterone B-Chemical secretion O rate O were O measured O . O In O both O groups O a O potassium B-Chemical deficit O developed O , O with O proportionally O larger O losses O from O the O extracellular O than O from O the O intracellular O compartment O . O In O the O normal O - O sodium B-Chemical group O the O highest O mean O potassium B-Chemical deficit O was O 176 O mmol O on O day O 9 O , O after O which O some O potassium B-Chemical was O regained O ; O in O the O low O - O sodium B-Chemical group O the O highest O deficit O was O 276 O mmol O on O day O 13 O . O The O normal O - O sodium B-Chemical group O showed O an O immediate O but O temporary O rise O of O the O renin O and O aldosterone B-Chemical levels O ; O in O the O low O - O sodium B-Chemical group O renin O and O aldosterone B-Chemical increased O more O slowly O but O remained O elevated O . O It O is O concluded O that O dietary O sodium B-Chemical restriction O increases O diuretic O - O induced O potassium B-Chemical loss O , O presumably O by O an O increased O activity O of O the O renin O - O angiotensin B-Chemical - O aldosterone B-Chemical system O , O while O sodium B-Chemical delivery O to O the O distal O renal O tubules O remains O sufficiently O high O to O allow O increased O potassium B-Chemical secretion O . O Reversal O of O neuroleptic O - O induced O catalepsy B-Disease by O novel O aryl B-Chemical - I-Chemical piperazine I-Chemical anxiolytic O drugs O . O The O novel O anxiolytic O drug O , O buspirone B-Chemical , O reverses O catalepsy B-Disease induced O by O haloperidol B-Chemical . O A O series O of O aryl B-Chemical - I-Chemical piperazine I-Chemical analogues O of O buspirone B-Chemical and O other O 5 B-Chemical - I-Chemical hydroxytryptaminergic I-Chemical agonists I-Chemical were O tested O for O their O ability O to O reverse O haloperidol B-Chemical induced O catalepsy B-Disease .

O The O effects O on O renal O function O on O two O different O immunosuppressive O protocols O were O evaluated O retrospectively O in O two O subsequent O groups O of O heart O transplant O recipients O . O In O group O I O , O cyclosporine B-Chemical was O given O before O the O procedure O at O a O loading O dose O of O 17 O . O 5 O mg O / O kg O and O then O continued O after O the O procedure O to O keep O a O whole O blood O level O about O 1000 O ng O / O ml O . O In O group O II O , O cyclosporine B-Chemical was O started O only O after O the O procedure O at O a O lower O dosage O and O was O complemented O by O azathioprine B-Chemical , O which O was O used O for O the O first O postoperative O week O . O Group O II O showed O a O better O perioperative O renal O function O as O determined O by O serum O blood O urea B-Chemical nitrogen I-Chemical and O serum O creatinine B-Chemical levels O . O Group O II O also O showed O a O significant O decrease O of O chronic O nephrotoxicity B-Disease secondary O to O long O - O term O therapy O with O cyclosporine B-Chemical . O Despite O this O improvement O in O late O renal O function O , O group O II O still O shows O a O slow O rise O in O serum O creatinine B-Chemical . O We O think O that O even O these O lower O dosages O of O cyclosporine B-Chemical can O cause O chronic O nephrotoxicity B-Disease and O that O further O modification O of O the O immunosuppressive O regimen O is O required O to O completely O abolish O this O toxic O side O effect O . O Ethopropazine B-Chemical and O benztropine B-Chemical in O neuroleptic O - O induced O parkinsonism B-Disease . O In O a O 12 O - O week O controlled O study O ethopropazine B-Chemical was O compared O to O benztropine B-Chemical in O the O treatment O of O parkinsonism B-Disease induced O by O fluphenazine B-Chemical enanthate I-Chemical in O 60 O schizophrenic B-Disease outpatients O . O Ethopropazine B-Chemical and O benztropine B-Chemical were O found O to O be O equally O effective O in O controlling O parkinsonian B-Disease symptoms I-Disease and O were O as O efficacious O as O procyclidine B-Chemical , O their O previous O antiparkinsonian O drug O .

O Relative O efficacy O and O toxicity B-Disease of O netilmicin B-Chemical and O tobramycin B-Chemical in O oncology O patients O . O We O prospectively O compared O the O efficacy O and O safety O of O netilmicin B-Chemical sulfate I-Chemical or O tobramycin B-Chemical sulfate I-Chemical in O conjunction O with O piperacillin B-Chemical sodium I-Chemical in O 118 O immunocompromised O patients O with O presumed O severe O infections B-Disease . O The O two O treatment O regimens O were O equally O efficacious O . O Nephrotoxicity B-Disease occurred O in O a O similar O proportion O in O patients O treated O with O netilmicin B-Chemical and O tobramycin B-Chemical ( O 17 O % O vs O 11 O % O ) O . O Ototoxicity B-Disease occurred O in O four O ( O 9 O .

O Aspirin B-Chemical or O salicylate B-Chemical ingestion O had O occurred O in O only O one O of O the O 20 O cases O ( O 5 O % O ) O , O and O paracetamol B-Chemical ( O acetaminophen B-Chemical ) O had O been O administered O in O only O six O of O the O cases O ( O 30 O % O ) O . O Pathologic O confirmation O of O the O diagnosis O of O Reye B-Disease syndrome I-Disease was O accomplished O in O 90 O % O of O the O cases O . O The O incidence O of O Reye B-Disease syndrome I-Disease in O New O South O Wales O , O Australia O , O is O estimated O from O this O study O to O be O approximately O nine O cases O per O 1 O million O children O compared O with O recent O US O data O of O ten O to O 20 O cases O per O 1 O million O children O and O three O to O seven O cases O per O 1 O million O children O in O Great O Britain O .

O Bromocriptine B-Chemical given O in O high O doses O has O been O associated O with O psychosis B-Disease in O patients O receiving O the O drug O for O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease . O These O cases O demonstrate O that O bromocriptine B-Chemical may O cause O psychosis B-Disease even O when O given O in O low O doses O . O Hyperglycemic B-Disease acidotic I-Disease coma I-Disease and O death O in O Kearns B-Disease - I-Disease Sayre I-Disease syndrome I-Disease . O This O paper O presents O the O clinical O and O metabolic O findings O in O two O young O boys O with O long O - O standing O Kearns B-Disease - I-Disease Sayre I-Disease syndrome I-Disease . O Following O short O exposure O to O oral O prednisone B-Chemical , O both O boys O developed O lethargy B-Disease , O increasing O somnolence B-Disease , O polydipsia B-Disease , O polyphagia B-Disease , O and O polyuria B-Disease . O Both O presented O in O the O emergency O room O with O profound O coma B-Disease , O hypotension B-Disease , O severe O hyperglycemia B-Disease , O and O acidosis B-Disease . O Nonketotic O lactic B-Disease acidosis I-Disease was O present O in O one O and O ketosis B-Disease without O a O known O serum O lactate B-Chemical level O was O present O in O the O other O . O Respiratory B-Disease failure I-Disease rapidly O ensued O and O both O patients O expired O in O spite O of O efforts O at O resuscitation O . O We O believe O these O two O cases O represent O a O newly O described O and O catastrophic O metabolic B-Disease - I-Disease endocrine I-Disease failure I-Disease in O the O Kearns B-Disease - I-Disease Sayre I-Disease syndrome I-Disease . O Experimental O cyclosporine B-Chemical nephrotoxicity B-Disease : O risk O of O concomitant O chemotherapy O . O The O role O of O cyclosporine B-Chemical ( O CSA B-Chemical ) O alone O or O in O combination O with O various O chemotherapeutics O in O the O development O of O renal B-Disease toxicity I-Disease was O evaluated O in O rats O . O Administration O of O 20 O mg O / O kg O / O day O CSA B-Chemical for O 4 O weeks O caused O renal O functional O and O structural O changes O similar O to O those O reported O in O man O . O The O combined O administration O of O CSA B-Chemical and O various O chemotherapeutic O drugs O with O a O nephrotoxic B-Disease potential O , O such O as O gentamicin B-Chemical ( O at O therapeutic O doses O ) O , O amphothericin B-Chemical B I-Chemical and O ketoconazole B-Chemical , O which O are O frequently O used O in O immunosuppressed O patients O , O did O not O aggravate O the O CSA B-Chemical induced O toxicity B-Disease in O the O rat O model O . O Gentamicin B-Chemical at O toxic O doses O , O however O , O increased O CSA B-Chemical nephrotoxicity B-Disease . O Thus O , O the O nephrotoxicity B-Disease induced O by O CSA B-Chemical has O a O different O pathogenetic O mechanism O . O Diuretics O , O potassium B-Chemical and O arrhythmias B-Disease in O hypertensive B-Disease coronary B-Disease disease I-Disease . O It O has O been O proposed O that O modest O changes O in O plasma O potassium B-Chemical can O alter O the O tendency O towards O cardiac B-Disease arrhythmias I-Disease . O If O this O were O so O , O patients O with O coronary B-Disease artery I-Disease disease I-Disease might O be O especially O susceptible O . O Thus O , O myocardial O electrical O excitability O was O measured O in O patients O with O mild O essential O hypertension B-Disease and O known O coronary B-Disease artery I-Disease disease I-Disease after O 8 O weeks O of O treatment O with O a O potassium B-Chemical - O conserving O diuretic O ( O amiloride B-Chemical ) O and O a O similar O period O on O a O potassium B-Chemical - O losing O diuretic O ( O chlorthalidone B-Chemical ) O in O a O randomised O study O . O Plasma O potassium B-Chemical concentrations O were O on O average O 1 O mmol O / O L O lower O during O the O chlorthalidone B-Chemical phase O compared O to O amiloride B-Chemical therapy O . O Blood O pressure O and O volume O states O as O assessed O by O bodyweight O , O plasma O renin O and O noradrenaline B-Chemical ( O norepinephrine B-Chemical ) O concentrations O were O similar O on O the O 2 O regimens O . O Compared O to O amiloride B-Chemical treatment O , O the O chlorthalidone B-Chemical phase O was O associated O with O an O increased O frequency O of O ventricular B-Disease ectopic I-Disease beats I-Disease ( O 24 O - O hour O Holter O monitoring O ) O and O a O higher O Lown O grading O , O increased O upslope O and O duration O of O the O monophasic O action O potential O , O prolonged O ventricular O effective O refractory O period O , O and O increased O electrical O instability O during O programmed O ventricular O stimulation O . O The O above O results O indicate O that O because O potassium B-Chemical - O losing O diuretic O therapy O can O increase O myocardial O electrical O excitability O in O patients O with O ischaemic B-Disease heart I-Disease disease I-Disease , O even O minor O falls O in O plasma O potassium B-Chemical concentrations O are O probably O best O avoided O in O such O patients O . O Transketolase O abnormality O in O tolazamide B-Chemical - O induced O Wernicke B-Disease ' I-Disease s I-Disease encephalopathy I-Disease . O We O studied O a O thiamine B-Chemical - O dependent O enzyme O , O transketolase O , O from O fibroblasts O of O a O diabetic B-Disease patient O who O developed O Wernicke B-Disease ' I-Disease s I-Disease encephalopathy I-Disease when O treated O with O tolazamide B-Chemical , O in O order O to O delineate O if O this O patient O also O had O transketolase O abnormality O [ O high O Km O for O thiamine B-Chemical pyrophosphate I-Chemical ( O TPP B-Chemical ) O ] O , O as O previously O reported O in O postalcoholic O Wernicke B-Disease - I-Disease Korsakoff I-Disease syndrome I-Disease . O In O addition O to O this O patient O , O we O also O studied O this O enzyme O from O three O diabetic B-Disease kindreds O without O any O history O of O Wernicke B-Disease ' I-Disease s I-Disease encephalopathy I-Disease and O from O four O normal O controls O . O We O found O that O the O above O - O mentioned O patient O and O one O of O the O diabetic B-Disease kindreds O with O no O history O of O Wernicke B-Disease ' I-Disease s I-Disease encephalopathy I-Disease had O abnormal O transketolase O as O determined O by O its O Km O for O TPP B-Chemical . O These O data O suggest O a O similarity O between O postalcoholic O Wernicke B-Disease - I-Disease Korsakoff I-Disease syndrome I-Disease and O the O patient O with O tolazamide B-Chemical - O induced O Wernicke B-Disease ' I-Disease s I-Disease encephalopathy I-Disease from O the O standpoint O of O transketolase O abnormality O . O Bradycardia B-Disease due O to O trihexyphenidyl B-Chemical hydrochloride I-Chemical . O A O chronic O schizophrenic B-Disease patient O was O treated O with O an O anticholinergic O drug O , O trihexyphenidyl B-Chemical hydrochloride I-Chemical . O The O patient O developed O , O paradoxically O , O sinus O bradycardia B-Disease . O The O reaction O was O specific O to O trihexyphenidyl B-Chemical and O not O to O other O anticholinergic O drugs O . O This O antidyskinetic O drug O is O widely O used O in O clinical O psychiatric B-Disease practice O and O physicians O should O be O aware O of O this O side O effect O . O Post O - O operative O rigidity B-Disease after O fentanyl B-Chemical administration O . O A O case O of O thoraco O - O abdominal O rigidity B-Disease leading O to O respiratory B-Disease failure I-Disease is O described O in O the O post O - O operative O period O in O an O elderly O patient O who O received O a O moderate O dose O of O fentanyl B-Chemical . O This O was O successfully O reversed O by O naloxone B-Chemical . O The O mechanisms O possibly O implicated O in O this O accident O are O discussed O . O Anti O - O carcinogenic B-Disease action O of O phenobarbital B-Chemical given O simultaneously O with O diethylnitrosamine B-Chemical in O the O rat O . O The O present O work O has O been O planned O in O order O to O elucidate O the O effect O of O phenobarbital B-Chemical ( O PB B-Chemical : O 15 O mg O per O rat O of O ingested O dose O ) O on O carcinogenesis B-Disease when O it O is O administered O simultaneously O with O diethylnitrosamine B-Chemical ( O DEN B-Chemical : O 10 O mg O / O kg O / O day O ) O . O Wistar O rats O ( O 180 O g O ) O were O treated O by O DEN B-Chemical alone O or O by O DEN B-Chemical + O PB B-Chemical during O 2 O , O 4 O and O 6 O weeks O according O to O our O schedule O for O hepatocarcinogenesis B-Disease . O After O the O end O of O the O treatment O , O the O number O and O the O size O of O induced O PAS O positive O preneoplastic B-Disease foci I-Disease was O significantly O reduced O when O PB B-Chemical was O given O simultaneously O with O DEN B-Chemical for O 4 O and O 6 O weeks O .

O When O the O treatment O last O only O 2 O weeks O , O the O presence O of O PB B-Chemical did O not O change O significantly O the O last O parameters O . O In O DEN B-Chemical + O PB B-Chemical treated O rats O , O the O survival O was O prolonged O and O the O tumor B-Disease incidence O decreased O as O compared O with O the O results O obtained O by O DEN B-Chemical alone O . O It O is O concluded O that O PB B-Chemical , O which O promotes O carcinogenesis B-Disease when O administered O after O the O DEN B-Chemical treatment O , O reduces O the O carcinogen O effect O when O given O simultaneously O with O DEN B-Chemical . O This O ' O anti O - O carcinogen O ' O effect O acts O on O the O initiation O as O well O as O on O the O promotion O of O the O precancerous B-Disease lesions I-Disease .

O Bilateral B-Disease optic I-Disease neuropathy I-Disease due O to O combined O ethambutol B-Chemical and O isoniazid B-Chemical treatment O . O The O case O of O a O 40 O - O year O - O old O patient O who O underwent O an O unsuccessful O cadaver O kidney O transplantation O and O was O treated O with O ethambutol B-Chemical and O isoniazid B-Chemical is O reported O . O A O bilateral B-Disease retrobulbar I-Disease neuropathy I-Disease with O an O unusual O central O bitemporal O hemianopic O scotoma B-Disease was O found O .

O The O hazards O of O optic O nerve O toxicity B-Disease due O to O ethambutol B-Chemical are O known O . O We O emphasize O the O potential O danger O in O the O use O of O ethambutol B-Chemical and O isoniazid B-Chemical . O A O prospective O study O of O adverse O reactions O associated O with O vancomycin B-Chemical therapy O . O A O prospective O evaluation O of O the O efficacy O and O safety O of O vancomycin B-Chemical was O conducted O in O 54 O consecutive O patients O over O a O 16 O - O month O period O .

O Plasma O and O urinary O lipids O and O lipoproteins O during O the O development O of O nephrotic B-Disease syndrome I-Disease induced O in O the O rat O by O puromycin B-Chemical aminonucleoside I-Chemical . O This O study O was O undertaken O to O ascertain O whether O the O alterations O of O plasma O lipoproteins O found O in O nephrotic B-Disease syndrome I-Disease induced O by O puromycin B-Chemical aminonucleoside I-Chemical were O due O to O nephrotic B-Disease syndrome I-Disease per O se O , O or O , O at O least O in O part O , O to O the O aminonucleoside B-Chemical . O The O purpose O of O the O present O study O was O to O investigate O the O changes O in O plasma O and O urinary O lipoproteins O during O the O administration O of O puromycin B-Chemical aminonucleoside I-Chemical ( O 20 O mg O / O kg O for O 7 O days O ) O and O the O subsequent O development O of O nephrotic B-Disease syndrome I-Disease . O Since O massive O albuminuria B-Disease occurred O after O 6 O days O of O treatment O , O the O time O - O course O study O was O divided O into O two O stages O : O pre O - O nephrotic B-Disease stage O ( O day O 1 O - O 5 O ) O and O nephrotic B-Disease stage O ( O day O 6 O - O 11 O ) O . O In O pre O - O nephrotic B-Disease stage O the O plasma O level O of O fatty B-Chemical acids I-Chemical , O triacylglycerol B-Chemical and O VLDL O decreased O while O that O of O phospholipid O , O cholesteryl B-Chemical esters I-Chemical and O HDL O remained O constant O . O Plasma O apolipoprotein O A O - O I O tended O to O increase O ( O 40 O % O increase O at O day O 5 O ) O . O At O the O beginning O of O nephrotic B-Disease stage O ( O day O 6 O ) O the O concentration O of O plasma O albumin O dropped O to O a O very O low O level O , O while O that O of O apolipoprotein O A O - O I O increased O abruptly O ( O 4 O - O fold O increase O ) O and O continued O to O rise O , O although O less O steeply O , O in O the O following O days O . O The O plasma O concentration O of O HDL O followed O the O same O pattern O . O Plasma O VLDL O and O LDL O increased O at O a O later O stage O ( O day O 9 O ) O . O Plasma O apolipoprotein O A O - O I O was O found O not O only O in O HDL O ( O 1 O . O 063 O - O 1 O . O 210 O g O / O ml O ) O but O also O in O the O LDL O density O class O ( O 1 O .

O In O the O pre O - O nephrotic B-Disease stage O lipoproteinuria O was O negligible O , O while O in O the O early O nephrotic B-Disease stage O the O urinary O loss O of O plasma O lipoproteins O consisted O mainly O of O HDL O . O These O observations O indicate O that O puromycin B-Chemical aminonucleoside I-Chemical alters O plasma O lipoproteins O by O lowering O VLDL O and O increasing O HDL O . O It O is O likely O that O the O early O and O striking O increase O of O plasma O HDL O found O in O nephrotic B-Disease rats O is O related O to O a O direct O effect O of O the O drug O on O HDL O metabolism O .

O Rats O treated O by O unloaded O NP O behaved O as O controls O . O These O results O demonstrate O that O , O in O these O experimental O conditions O , O DXNP O killed O less O animals O than O free O DX B-Chemical , O despite O of O an O enhanced O renal B-Disease toxicity I-Disease of O the O former O .

O OBJECTIVE O : O To O evaluate O the O possible O protective O effects O of O misoprostol B-Chemical on O renal O function O in O hospitalized O elderly O patients O treated O with O indomethacin B-Chemical . O METHODS O : O Forty O - O five O hospitalized O elderly O patients O ( O > O 65 O years O old O ) O who O required O therapy O with O nonsteroidal O antiinflammatory O drugs O ( O NSAID O ) O were O randomly O assigned O to O receive O either O indomethacin B-Chemical , O 150 O mg O / O day O ( O Group O A O ) O , O or O indomethacin B-Chemical 150 O mg O / O day O plus O misoprostol B-Chemical at O 0 O . O 6 O mg O / O day O ( O Group O B O ) O . O Laboratory O variables O of O renal O function O [ O serum O creatinine B-Chemical , O blood B-Chemical urea I-Chemical nitrogen I-Chemical ( O BUN B-Chemical ) O and O electrolytes O ] O were O evaluated O before O initiation O of O therapy O and O every O 2 O days O , O until O termination O of O the O study O ( O a O period O of O at O least O 6 O days O ) O . O Response O to O treatment O was O estimated O by O the O visual O analog O scale O for O severity O of O pain B-Disease . O RESULTS O : O Forty O - O two O patients O completed O the O study O , O 22 O in O Group O A O and O 20 O in O Group O B O . O BUN B-Chemical and O creatinine B-Chemical increased O by O > O 50 O % O of O baseline O levels O in O 54 O and O 45 O % O of O Group O A O patients O , O respectively O , O compared O to O only O 20 O and O 10 O % O of O Group O B O patients O ( O p O < O 0 O .

O The O mean O increments O in O BUN B-Chemical , O creatinine B-Chemical , O and O K B-Chemical were O reduced O by O 63 O , O 80 O , O and O 42 O % O , O respectively O , O in O Group O B O patients O compared O to O Group O A O . O Response O to O treatment O did O not O differ O significantly O between O the O 2 O groups O . O CONCLUSION O : O Hospitalized O elderly O patients O are O at O risk O for O developing O indomethacin B-Chemical related O renal B-Disease dysfunction I-Disease . O Addition O of O misoprostol B-Chemical can O minimize O this O renal B-Disease impairment I-Disease without O affecting O pain B-Disease control O .

O However O , O there O are O no O reports O describing O the O effects O of O chronic O abuse O . O This O report O describes O a O case O of O cognitive B-Disease deterioration I-Disease resulting O from O prolonged O use O of O DM B-Chemical . O Effects O of O ouabain B-Chemical on O myocardial O oxygen B-Chemical supply O and O demand O in O patients O with O chronic O coronary B-Disease artery I-Disease disease I-Disease . O A O hemodynamic O , O volumetric O , O and O metabolic O study O in O patients O without O heart B-Disease failure I-Disease . O The O effects O of O digitalis B-Chemical glycosides I-Chemical on O myocardial O oxygen B-Chemical supply O and O demand O are O of O particular O interest O in O the O presence O of O obstructive O coronary B-Disease artery I-Disease disease I-Disease , O but O have O not O been O measured O previously O in O man O . O We O assessed O the O effects O of O ouabain B-Chemical ( O 0 O .

O Because O the O protocol O was O long O and O involved O interventions O which O might O affect O the O determinations O , O we O also O studied O in O nine O patients O using O an O identical O protocol O except O that O ouabain B-Chemical administration O was O omitted O . O Left O ventricular O end O - O diastolic O pressure O and O left O ventricular O end O - O diastolic O volume O fell O in O each O patient O given O ouabain B-Chemical , O even O though O they O were O initially O elevated O in O only O two O patients O . O Left O ventricular O end O - O diastolic O pressure O fell O from O 11 O . O 5 O + O / O - O 1 O . O 4 O ( O mean O + O / O - O SE O ) O to O 5 O . O 6 O + O / O - O 0 O . O 9 O mm O Hg O ( O P O less O than O 0 O .

O No O significant O change O in O myocardial O oxygen B-Chemical consumption O occurred O after O ouabain B-Chemical administration O but O this O may O be O related O to O a O greater O decrease O in O mean O arterial O pressure O in O the O ouabain B-Chemical patients O than O in O the O control O patients O . O We O conclude O that O in O patients O with O chronic O coronary B-Disease artery I-Disease disease I-Disease who O are O not O in O clinical O congestive B-Disease heart I-Disease failure I-Disease left B-Disease ventricular I-Disease end I-Disease - I-Disease diastolic I-Disease volume I-Disease falls I-Disease after O ouabain B-Chemical administration O even O when O it O is O initially O normal O . O Though O this O fall O would O be O associated O with O a O decrease O in O wall O tension O , O and O , O therefore O , O of O myocardial O oxygen B-Chemical consumption O , O it O may O not O be O of O sufficient O magnitude O to O prevent O a O net O increase O in O myocardial O oxygen B-Chemical consumption O . O Nevertheless O , O compensatory O mechanisms O prevent O a O deterioration O of O resting O myocardial O metabolism O . O Dexamethasone B-Chemical - O induced O ocular B-Disease hypertension I-Disease in O perfusion O - O cultured O human O eyes O . O PURPOSE O : O Glucocorticoid O administration O can O lead O to O the O development O of O ocular B-Disease hypertension I-Disease and O corticosteroid B-Disease glaucoma I-Disease in O a O subset O of O the O population O through O a O decrease O in O the O aqueous O humor O outflow O facility O . O The O purpose O of O this O study O was O to O determine O whether O glucocorticoid O treatment O can O directly O affect O the O outflow O facility O of O isolated O , O perfusion O - O cultured O human O eyes O . O METHODS O : O The O anterior O segments O of O human O donor O eyes O from O regional O eye O banks O were O placed O in O a O constant O flow O , O variable O pressure O perfusion O culture O system O . O Paired O eyes O were O perfused O in O serum O - O free O media O with O or O without O 10 O ( O - O 7 O ) O M O dexamethasone B-Chemical for O 12 O days O . O Intraocular O pressure O was O monitored O daily O . O After O incubation O , O the O eyes O were O morphologically O characterized O by O light O microscopy O , O transmission O and O scanning O electron O microscopy O , O and O scanning O laser O confocal O microscopy O . O RESULTS O : O A O significant O increase O in O intraocular O pressure O developed O in O 13 O of O the O 44 O pairs O of O eyes O perfused O with O dexamethasone B-Chemical with O an O average O pressure O rise O of O 17 O .

O The O contralateral O control O eyes O , O which O did O not O receive O dexamethasone B-Chemical , O maintained O a O stable O intraocular O pressure O during O the O same O period O . O The O outflow O pathway O of O the O untreated O eyes O appeared O morphologically O normal O . O In O contrast O , O the O dexamethasone B-Chemical - O treated O hypertensive B-Disease eyes I-Disease had O thickened O trabecular O beams O , O decreased O intertrabecular O spaces O , O thickened O juxtacanalicular O tissue O , O activated O trabecular O meshwork O cells O , O and O increased O amounts O of O amorphogranular O extracellular O material O , O especially O in O the O juxtacanalicular O tissue O and O beneath O the O endothelial O lining O of O the O canal O of O Schlemm O . O The O dexamethasone B-Chemical - O treated O nonresponder O eyes O appeared O to O be O morphologically O similar O to O the O untreated O eyes O , O although O several O subtle O dexamethasone B-Chemical - O induced O morphologic O changes O were O evident O . O CONCLUSION O : O Dexamethasone B-Chemical treatment O of O isolated O , O perfusion O - O cultured O human O eyes O led O to O the O generation O of O ocular B-Disease hypertension I-Disease in O approximately O 30 O % O of O the O dexamethasone B-Chemical - O treated O eyes O . O Steroid B-Chemical treatment O resulted O in O morphologic O changes O in O the O trabecular O meshwork O similar O to O those O reported O for O corticosteroid B-Disease glaucoma I-Disease and O open B-Disease angle I-Disease glaucoma I-Disease . O This O system O may O provide O an O acute O model O in O which O to O study O the O pathogenic O mechanisms O involved O in O steroid B-Disease glaucoma I-Disease and O primary B-Disease open I-Disease angle I-Disease glaucoma I-Disease .

O ( O ABSTRACT O TRUNCATED O AT O 250 O WORDS O ) O Prolonged O paralysis B-Disease due O to O nondepolarizing B-Chemical neuromuscular I-Chemical blocking I-Chemical agents I-Chemical and O corticosteroids B-Chemical . O The O long O - O term O use O of O nondepolarizing B-Chemical neuromuscular I-Chemical blocking I-Chemical agents I-Chemical ( O ND B-Chemical - I-Chemical NMBA I-Chemical ) O has O recently O been O implicated O as O a O cause O of O prolonged O muscle B-Disease weakness I-Disease , O although O the O site O of O the O lesion O and O the O predisposing O factors O have O been O unclear O . O We O report O 3 O patients O ( O age O 37 O - O 52 O years O ) O with O acute O respiratory B-Disease insufficiency I-Disease who O developed O prolonged O weakness B-Disease following O the O discontinuation O of O ND B-Chemical - I-Chemical NMBAs I-Chemical . O Two O patients O also O received O intravenous O corticosteroids B-Chemical . O Renal O function O was O normal O but O hepatic O function O was O impaired O in O all O patients O , O and O all O had O acidosis B-Disease . O Electrophysiologic O studies O revealed O low O amplitude O compound O motor O action O potentials O , O normal O sensory O studies O , O and O fibrillations O . O Repetitive O stimulation O at O 2 O Hz O showed O a O decremental O response O in O 2 O patients O . O The O serum O vecuronium B-Chemical level O measured O in O 1 O patient O 14 O days O after O the O drug O had O been O discontinued O was O 172 O ng O / O mL O . O A O muscle O biopsy O in O this O patient O showed O loss B-Disease of I-Disease thick I-Disease , I-Disease myosin I-Disease filaments I-Disease . O The O weakness B-Disease in O these O patients O is O due O to O pathology B-Disease at I-Disease both I-Disease the I-Disease neuromuscular I-Disease junction I-Disease ( O most O likely O due O to O ND B-Chemical - I-Chemical NMBA I-Chemical ) O and O muscle O ( O most O likely O due O to O corticosteroids B-Chemical ) O . O Hepatic B-Disease dysfunction I-Disease and O acidosis B-Disease are O contributing O risk O factors O . O Failure O of O ancrod O in O the O treatment O of O heparin B-Chemical - O induced O arterial O thrombosis B-Disease . O The O morbidity O and O mortality O associated O with O heparin B-Chemical - O induced O thrombosis B-Disease remain O high O despite O numerous O empirical O therapies O .

O The O authors O present O a O case O of O failure O of O ancrod O treatment O in O a O patient O with O heparin B-Chemical - O induced O thrombosis B-Disease . O Water B-Disease intoxication I-Disease associated O with O oxytocin B-Chemical administration O during O saline O - O induced O abortion B-Disease . O Four O cases O of O water B-Disease intoxication I-Disease in O connection O with O oxytocin B-Chemical administration O during O saline O - O induced O abortions B-Disease are O described O . O The O mechanism O of O water B-Disease intoxication I-Disease is O discussed O in O regard O to O these O cases O .

O They O were O then O treated O chronically O with O L B-Chemical - I-Chemical DOPA I-Chemical / I-Chemical benserazide I-Chemical 50 O / O 12 O . O 5 O mg O / O kg O given O orally O daily O for O 2 O months O . O This O dose O produced O a O striking O antiparkinsonian O effect O , O but O all O animals O manifested O dyskinesia B-Disease . O A O series O of O agents O acting O primarily O on O neurotransmitters O other O than O dopamine B-Chemical were O then O tested O in O combination O with O L B-Chemical - I-Chemical DOPA I-Chemical to O see O if O the O dyskinetic B-Disease movements O would O be O modified O . O Several O drugs O , O including O clonidine B-Chemical , O physostigmine B-Chemical , O methysergide B-Chemical , O 5 B-Chemical - I-Chemical MDOT I-Chemical , O propranolol B-Chemical , O and O MK B-Chemical - I-Chemical 801 I-Chemical , O markedly O reduced O the O dyskinetic B-Disease movements O but O at O the O cost O of O a O return O of O parkinsonian B-Disease symptomatology O . O However O , O yohimbine B-Chemical and O meperidine B-Chemical reduced O predominantly O the O dyskinetic B-Disease movements O . O Baclofen B-Chemical was O also O useful O in O one O monkey O against O a O more O dystonic B-Disease form O of O dyskinesia B-Disease . O Atropine B-Chemical converted O the O dystonic B-Disease movements O into O chorea B-Disease . O Hallucinations B-Disease and O ifosfamide B-Chemical - O induced O neurotoxicity B-Disease . O BACKGROUND O : O Hallucinations B-Disease as O a O symptom O of O central O neurotoxicity B-Disease are O a O known O but O poorly O described O side O effect O of O ifosfamide B-Chemical . O Most O cases O of O ifosfamide B-Chemical - O induced O hallucinations B-Disease have O been O reported O with O other O mental O status O changes O . O METHODS O : O The O authors O interviewed O six O persons O with O ifosfamide B-Chemical - O induced O hallucinations B-Disease in O the O presence O of O a O clear O sensorium O . O All O patients O were O receiving O high O - O dose O ifosfamide B-Chemical as O part O of O their O bone O marrow O transplant O procedure O . O RESULTS O : O Hallucinations B-Disease occurred O only O when O the O patient O ' O s O eyes O were O closed O and O , O in O all O but O one O case O , O were O reported O as O disturbing O or O frightening O . O Underreporting O of O these O hallucinations B-Disease by O patients O is O likely O . O CONCLUSIONS O : O Hallucinations B-Disease may O be O the O sole O or O first O manifestation O of O neurotoxicity B-Disease . O The O incidence O may O be O dose O and O infusion O - O time O related O . O The O clinician O should O be O alerted O for O possible O ifosfamide B-Chemical - O induced O hallucinations B-Disease , O which O may O occur O without O other O signs O of O neurotoxicity B-Disease . O " O Eyes O - O closed O " O hallucinatory B-Disease experiences O appear O to O be O an O unusual O feature O of O this O presentation O . O Patients O anxious O about O this O experience O respond O well O to O support O and O education O about O this O occurrence O . O Optimal O pharmacologic O management O of O disturbed O patients O is O unclear O . O If O agitation B-Disease becomes O marked O , O high O - O potency O neuroleptics O ( O i O . O e O . O , O haloperidol B-Chemical ) O may O be O effective O . O Photodistributed O nifedipine B-Chemical - O induced O facial O telangiectasia B-Disease . O Five O months O after O starting O nifedipine B-Chemical ( O Adalat B-Chemical ) O , O two O patients O developed O photodistributed O facial O telangiectasia B-Disease , O which O became O more O noticeable O with O time O . O Neither O patient O complained O of O photosensitivity O or O flushing B-Disease . O Both O patients O reported O a O significant O cosmetic O improvement O after O discontinuing O the O drug O . O One O commenced O the O closely O related O drug O amlodipine B-Chemical 3 O years O later O , O with O recurrence O of O telangiectasia B-Disease . O The O photodistribution O of O the O telangiectasia B-Disease suggests O a O significant O drug O / O light O interaction O . O Penicillamine B-Chemical - O induced O rapidly O progressive O glomerulonephritis B-Disease in O a O patient O with O rheumatoid B-Disease arthritis I-Disease . O A O 67 O - O year O - O old O woman O with O rheumatoid B-Disease arthritis I-Disease presented O rapidly O progressive O glomerulonephritis B-Disease ( O RPGN B-Disease ) O after O 5 O months O of O D B-Chemical - I-Chemical penicillamine I-Chemical ( O 250 O mg O / O day O ) O treatment O . O Light O microscopy O study O showed O severe O glomerulonephritis B-Disease with O crescent O formation O in O 60 O % O of O the O glomeruli O and O infiltration O of O inflammatory O cells O in O the O wall O of O an O arteriole O . O Immunofluorescence O revealed O scanty O granular O IgG O , O IgA O and O C3 O deposits O along O the O capillary O walls O and O mesangium O . O The O patient O was O treated O with O steroid B-Chemical pulse O , O plasmapheresis O , O cyclophosphamide B-Chemical and O antiplatelet B-Chemical agents I-Chemical . O A O complete O recovery O of O renal O function O was O achieved O in O a O few O weeks O . O This O new O case O of O RPGN B-Disease in O the O course O of O D B-Chemical - I-Chemical penicillamine I-Chemical treatment O emphasizes O the O need O for O frequent O monitoring O of O renal O function O and O evaluation O of O urinary O sediment O and O proteinuria B-Disease in O these O patients O . O The O prompt O discontinuation O of O D B-Chemical - I-Chemical penicillamine I-Chemical and O vigorous O treatment O measures O could O allow O for O a O good O prognosis O as O in O this O case O . O A O case O of O polymyositis B-Disease in O a O patient O with O primary B-Disease biliary I-Disease cirrhosis I-Disease treated O with O D B-Chemical - I-Chemical penicillamine I-Chemical . O Although O D B-Chemical - I-Chemical penicillamine I-Chemical has O been O used O for O many O rheumatologic B-Disease diseases I-Disease , O toxicity B-Disease limits O its O usefulness O in O many O patients O . O Polymyositis B-Disease / O dermatomyositis B-Disease can O develop O as O one O of O the O autoimmune O complications O of O D B-Chemical - I-Chemical penicillamine I-Chemical treatment O , O but O its O exact O pathogenesis O remains O unclear O . O We O report O a O patient O with O primary B-Disease biliary I-Disease cirrhosis I-Disease , O who O developed O polymyositis B-Disease while O receiving O D B-Chemical - I-Chemical penicillamine I-Chemical therapy O . O We O described O the O special O clinical O course O of O the O patient O . O Patients O receiving O D B-Chemical - I-Chemical penicillamine I-Chemical therapy O should O be O followed O carefully O for O the O development O of O autoimmune O complications O like O polymyositis B-Disease / O dermatomyositis B-Disease . O Hyperalgesia B-Disease and O myoclonus B-Disease in O terminal O cancer B-Disease patients O treated O with O continuous O intravenous O morphine B-Chemical . O Eight O cancer B-Disease patients O in O the O terminal O stages O of O the O disease O treated O with O high O doses O of O intravenous O morphine B-Chemical developed O hyperalgesia B-Disease . O All O cases O were O retrospectively O sampled O from O three O different O hospitals O in O Copenhagen O . O Five O patients O developed O universal O hyperalgesia B-Disease and O hyperesthesia B-Disease which O in O 2 O cases O were O accompanied O by O myoclonus B-Disease . O In O 3 O patients O a O pre O - O existing O neuralgia B-Disease increased O to O excruciating O intensity O and O in O 2 O of O these O cases O myoclonus B-Disease occurred O simultaneously O . O Although O only O few O clinical O descriptions O of O the O relationship O between O hyperalgesia B-Disease / O myoclonus B-Disease and O high O doses O of O morphine B-Chemical are O available O , O experimental O support O from O animal O studies O indicates O that O morphine B-Chemical , O or O its O metabolites O , O plays O a O causative O role O for O the O observed O behavioural O syndrome O . O The O possible O mechanisms O are O discussed O and O treatment O proposals O given O suggesting O the O use O of O more O efficacious O opioids O with O less O excitatory O potency O in O these O situations O . O Liposomal O daunorubicin B-Chemical in O advanced O Kaposi B-Disease ' I-Disease s I-Disease sarcoma I-Disease : O a O phase O II O study O . O We O report O a O non O - O randomized O Phase O II O clinical O trial O to O assess O the O efficacy O and O safety O of O liposomal O daunorubicin B-Chemical ( O DaunoXome O ) O in O the O treatment O of O AIDS B-Disease related O Kaposi B-Disease ' I-Disease s I-Disease sarcoma I-Disease . O Eleven O homosexual O men O with O advanced O Kaposi B-Disease ' I-Disease s I-Disease sarcoma I-Disease were O entered O in O the O trial O . O Changes O in O size O , O colour O and O associated O oedema B-Disease of O selected O ' O target O ' O lesions O were O measured O . O Clinical O , O biochemical O and O haematological O toxicities B-Disease were O assessed O . O Ten O subjects O were O evaluated O . O A O partial O response O was O achieved O in O four O , O of O whom O two O subsequently O relapsed O . O Stabilization O of O Kaposi B-Disease ' I-Disease s I-Disease sarcoma I-Disease occurred O in O the O remaining O six O , O maintained O until O the O end O of O the O trial O period O in O four O . O The O drug O was O generally O well O tolerated O , O with O few O mild O symptoms O of O toxicity B-Disease . O The O main O problem O encountered O was O haematological O toxicity B-Disease , O with O three O subjects O experiencing O severe O neutropenia B-Disease ( O neutrophil O count O < O 0 O . O 5 O x O 10 O ( O 9 O ) O / O l O ) O . O There O was O no O evidence O of O cardiotoxicity B-Disease . O In O this O small O patient O sample O , O liposomal O daunorubicin B-Chemical was O an O effective O and O well O tolerated O agent O in O the O treatment O of O Kaposi B-Disease ' I-Disease s I-Disease sarcoma I-Disease . O Long O - O term O effects O of O vincristine B-Chemical on O the O peripheral O nervous O system O . O Forty O patients O with O Non B-Disease - I-Disease Hodgkin I-Disease ' I-Disease s I-Disease Lymphoma I-Disease treated O with O vincristine B-Chemical between O 1984 O and O 1990 O ( O cumulative O dose O 12 O mg O in O 18 O - O 24 O weeks O ) O were O investigated O in O order O to O evaluate O the O long O term O effects O of O vincristine B-Chemical on O the O peripheral O nervous O system O . O The O patients O were O interviewed O with O emphasis O on O neuropathic B-Disease symptoms I-Disease . O Physical O and O quantitative O sensory O examination O with O determination O of O vibratory O perception O and O thermal O discrimination O thresholds O were O performed O , O four O to O 77 O months O ( O median O 34 O months O ) O after O vincristine B-Chemical treatment O . O Twenty O - O seven O patients O reported O neuropathic B-Disease symptoms I-Disease . O In O 13 O of O these O 27 O patients O symptoms O were O still O present O at O the O time O of O examination O . O In O these O patients O sensory O signs O and O symptoms O predominated O . O In O the O other O 14 O patients O symptoms O had O been O present O in O the O past O . O Symptoms O persisted O maximally O 40 O months O since O cessation O of O therapy O . O There O was O no O age O difference O between O patients O with O and O without O complaints O at O the O time O of O examination O . O Normal O reflexes O were O found O in O two O third O of O patients O . O Neuropathic O complaints O were O not O very O troublesome O on O the O long O term O . O It O is O concluded O that O with O the O above O mentioned O vincristine B-Chemical dose O schedule O signs O and O symptoms O of O vincristine B-Chemical neuropathy B-Disease are O reversible O for O a O great O deal O and O prognosis O is O fairly O good O . O Hepatic O adenomas B-Disease and O focal B-Disease nodular I-Disease hyperplasia I-Disease of O the O liver O in O young O women O on O oral B-Chemical contraceptives I-Chemical : O case O reports O . O Two O cases O of O hepatic O adenoma B-Disease and O one O of O focal B-Disease nodular I-Disease hyperplasia I-Disease presumably O associated O with O the O use O of O oral B-Chemical contraceptives I-Chemical , O are O reported O . O Special O reference O is O made O to O their O clinical O presentation O , O which O may O be O totally O asymptomatic O . O Liver O - O function O tests O are O of O little O diagnostic O value O , O but O valuable O information O may O be O obtained O from O both O liver O scanning O and O hepatic O angiography O . O Histologic O differences O and O clinical O similarities O between O hepatic O adenoma B-Disease and O focal B-Disease nodular I-Disease hyperplasia I-Disease of O the O liver O are O discussed O . O Loss O of O glutamate B-Chemical decarboxylase O mRNA O - O containing O neurons O in O the O rat O dentate O gyrus O following O pilocarpine B-Chemical - O induced O seizures B-Disease . O In O situ O hybridization O methods O were O used O to O determine O if O glutamic B-Chemical acid I-Chemical decarboxylase O ( O GAD O ) O mRNA O - O containing O neurons O within O the O hilus O of O the O dentate O gyrus O are O vulnerable O to O seizure B-Disease - O induced O damage O in O a O model O of O chronic O seizures B-Disease . O Sprague O - O Dawley O rats O were O injected O intraperitoneally O with O pilocarpine B-Chemical , O and O the O hippocampal O formation O was O studied O histologically O at O 1 O , O 2 O , O 4 O , O and O 8 O week O intervals O after O pilocarpine B-Chemical - O induced O seizures B-Disease . O In O situ O hybridization O histochemistry O , O using O a O digoxigenin B-Chemical - O labeled O GAD O cRNA O probe O , O demonstrated O a O substantial O decrease O in O the O number O of O GAD O mRNA O - O containing O neurons O in O the O hilus O of O the O dentate O gyrus O in O the O pilocarpine B-Chemical - O treated O rats O as O compared O to O controls O at O all O time O intervals O . O Additional O neuronanatomical O studies O , O including O cresyl B-Chemical violet I-Chemical staining O , O neuronal B-Disease degeneration I-Disease methods O , O and O histochemical O localization O of O glial O fibrillary O acidic O protein O , O suggested O that O the O decrease O in O the O number O of O GAD O mRNA O - O containing O neurons O was O related O to O neuronal B-Disease loss I-Disease rather O than O to O a O decrease O in O GAD O mRNA O levels O . O The O loss O of O GAD O mRNA O - O containing O neurons O in O the O hilus O contrasted O with O the O relative O preservation O of O labeled O putative O basket O cells O along O the O inner O margin O of O the O granule O cell O layer O . O Quantitative O analyses O of O labeled O neurons O in O three O regions O of O the O dentate O gyrus O in O the O 1 O and O 2 O week O groups O showed O statistically O significant O decreases O in O the O mean O number O of O GAD O mRNA O - O containing O neurons O in O the O hilus O of O both O groups O of O experimental O animals O . O No O significant O differences O were O found O in O the O molecular O layer O or O the O granule O cell O layer O , O which O included O labeled O neurons O along O the O lower O margin O of O the O granule O cell O layer O . O The O results O indicate O that O , O in O this O model O , O a O subpopulation O of O GAD O mRNA O - O containing O neurons O within O the O dentate O gyrus O is O selectively O vulnerable O to O seizure B-Disease - O induced O damage O . O Such O differential O vulnerability O appears O to O be O another O indication O of O the O heterogeneity O of O GABA B-Chemical neurons O . O Effects O of O deliberate O hypotension B-Disease induced O by O labetalol B-Chemical with O isoflurane B-Chemical on O neuropsychological O function O . O The O effect O of O deliberate O hypotension B-Disease on O brain O function O measured O by O neuropsychological O tests O was O studied O in O 41 O adult O patients O . O Twenty O - O four O patients O were O anaesthetized O for O middle O - O ear O surgery O with O deliberate O hypotension B-Disease induced O by O labetalol B-Chemical with O isoflurane B-Chemical ( O hypotensive B-Disease group O ) O . O Seventeen O patients O without O hypotension B-Disease served O as O a O control O group O . O The O mean O arterial O pressure O was O 77 O + O / O - O 2 O mmHg O ( O 10 O . O 3 O + O / O - O 0 O . O 3 O kPa O ) O before O hypotension B-Disease and O 50 O + O / O - O 0 O mmHg O ( O 6 O . O 7 O + O / O - O 0 O . O 0 O kPa O ) O during O hypotension B-Disease in O the O hypotensive B-Disease group O , O and O 86 O + O / O - O 2 O mmHg O ( O 11 O . O 5 O + O / O - O 0 O . O 3 O kPa O ) O during O anaesthesia O in O the O control O group O . O The O following O psychological O tests O were O performed O : O four O subtests O of O the O Wechsler O Adult O Intelligence O Scale O ( O similarities O , O digit O span O , O vocabulary O and O digit O symbol O ) O , O Trail O - O Making O tests O A O and O B O , O Zung O tests O ( O self O - O rating O anxiety B-Disease scale O and O self O - O rating O depression B-Disease scale O ) O and O two O - O part O memory O test O battery O with O immediate O and O delayed O recall O . O The O tests O were O performed O preoperatively O and O 2 O days O postoperatively O . O There O were O no O statistically O significant O differences O between O the O groups O in O any O of O the O tests O in O the O changes O from O preoperative O value O to O postoperative O value O . O The O results O indicate O that O hypotension B-Disease induced O by O labetalol B-Chemical with O isoflurane B-Chemical has O no O significant O harmful O effects O on O mental O functions O compared O to O normotensive O anaesthesia O . O Apparent O cure O of O rheumatoid B-Disease arthritis I-Disease by O bone O marrow O transplantation O . O We O describe O the O induction O of O sustained O remissions O and O possible O cure O of O severe O erosive O rheumatoid B-Disease arthritis I-Disease ( O RA B-Disease ) O by O bone O marrow O transplantation O ( O BMT O ) O in O 2 O patients O . O BMT O was O used O to O treat O severe O aplastic B-Disease anemia I-Disease which O was O caused O by O gold B-Chemical in O one O case O and O D B-Chemical - I-Chemical penicillamine I-Chemical in O the O other O . O In O the O 8 O and O 6 O years O since O the O transplants O ( O representing O 8 O and O 4 O years O since O cessation O of O all O immunosuppressive O therapy O , O respectively O ) O , O the O RA B-Disease in O each O case O has O been O completely O quiescent O . O Although O short O term O remission O of O severe O RA B-Disease following O BMT O has O been O reported O , O these O are O the O first O cases O for O which O prolonged O followup O has O been O available O . O This O experience O raises O the O question O of O the O role O of O BMT O itself O as O a O therapeutic O option O for O patients O with O uncontrolled O destructive O synovitis B-Disease . O Seizures B-Disease induced O by O combined O levomepromazine B-Chemical - O fluvoxamine B-Chemical treatment O . O We O report O a O case O of O combined O levomepromazine B-Chemical - O fluvoxamine B-Chemical treatment O - O induced O seizures B-Disease . O It O seems O that O combined O treatment O of O fluvoxamine B-Chemical with O phenothiazines B-Chemical may O possess O proconvulsive O activity O . O Case O report O : O pentamidine B-Chemical and O polymorphic O ventricular B-Disease tachycardia I-Disease revisited O . O Pentamidine B-Chemical isethionate I-Chemical has O been O associated O with O ventricular B-Disease tachyarrhythmias I-Disease , O including O torsade B-Disease de I-Disease pointes I-Disease . O This O article O reports O two O cases O of O this O complication O and O reviews O all O reported O cases O to O date O . O Pentamidine B-Chemical - O induced O torsade B-Disease de I-Disease pointes I-Disease may O be O related O to O serum O magnesium B-Chemical levels O and O hypomagnesemia B-Disease may O synergistically O induce O torsade O . O Torsade B-Disease de I-Disease pointes I-Disease occurred O after O an O average O of O 10 O days O of O treatment O with O pentamidine B-Chemical . O In O these O patients O , O no O other O acute O side O effects O of O pentamidine B-Chemical were O observed O . O Torsade B-Disease de I-Disease pointes I-Disease can O be O treated O when O recognized O early O , O possibly O without O discontinuation O of O pentamidine B-Chemical . O When O QTc B-Disease interval I-Disease prolongation I-Disease is O observed O , O early O magnesium B-Chemical supplementation O is O advocated O . O Efficacy O and O tolerability O of O lovastatin B-Chemical in O 3390 O women O with O moderate O hypercholesterolemia B-Disease . O OBJECTIVE O : O To O evaluate O the O efficacy O and O safety O of O lovastatin B-Chemical in O women O with O moderate O hypercholesterolemia B-Disease . O DESIGN O : O The O Expanded O Clinical O Evaluation O of O Lovastatin B-Chemical ( O EXCEL O ) O Study O , O a O multicenter O , O double O - O blind O , O diet O - O and O placebo O - O controlled O trial O , O in O which O participants O were O randomly O assigned O to O receive O placebo O or O lovastatin B-Chemical at O doses O of O 20 O or O 40 O mg O once O daily O , O or O 20 O or O 40 O mg O twice O daily O for O 48 O weeks O . O SETTING O : O Ambulatory O patients O recruited O by O 362 O participating O centers O throughout O the O United O States O . O PATIENTS O : O Women O ( O n O = O 3390 O ) O from O the O total O cohort O of O 8245 O volunteers O . O MEASUREMENTS O : O Plasma O total O , O low O - O density O lipoprotein O ( O LDL O ) O , O and O high O - O density O lipoprotein O ( O HDL O ) O cholesterol B-Chemical , O and O triglycerides B-Chemical ; O and O laboratory O and O clinical O evidence O of O adverse O events O monitored O periodically O throughout O the O study O . O RESULTS O : O Among O women O , O lovastatin B-Chemical ( O 20 O to O 80 O mg O / O d O ) O produced O sustained O ( O 12 O - O to O 48 O - O week O ) O , O dose O - O related O changes O ( O P O < O 0 O . O 001 O ) O : O decreases O in O LDL O cholesterol B-Chemical ( O 24 O % O to O 40 O % O ) O and O triglycerides B-Chemical ( O 9 O % O to O 18 O % O ) O , O and O increases O in O HDL O cholesterol B-Chemical ( O 6 O . O 7 O % O to O 8 O . O 6 O % O ) O . O Depending O on O the O dose O , O from O 82 O % O to O 95 O % O of O lovastatin B-Chemical - O treated O women O achieved O the O National O Cholesterol B-Chemical Education O Program O goal O of O LDL O cholesterol B-Chemical levels O less O than O 4 O . O 14 O mmol O / O L O ( O 160 O mg O / O dL O ) O , O and O 40 O % O to O 87 O % O achieved O the O goal O of O 3 O . O 36 O mmol O / O L O ( O 130 O mg O / O dL O ) O . O Successive O transaminase O elevations O greater O than O three O times O the O upper O limit O of O normal O occurred O in O 0 O . O 1 O % O of O women O and O were O dose O dependent O above O the O 20 O - O mg O dose O . O Myopathy B-Disease , O defined O as O muscle O symptoms O with O creatine B-Chemical kinase O elevations O greater O than O 10 O times O the O upper O limit O of O normal O , O was O rare O and O associated O with O the O highest O recommended O daily O dose O of O lovastatin B-Chemical ( O 80 O mg O ) O . O Estrogen O - O replacement O therapy O appeared O to O have O no O effect O on O either O the O efficacy O or O safety O profile O of O lovastatin B-Chemical . O CONCLUSION O : O Lovastatin B-Chemical is O highly O effective O and O generally O well O tolerated O as O therapy O for O primary O hypercholesterolemia B-Disease in O women O . O Tetany B-Disease and O rhabdomyolysis B-Disease due O to O surreptitious O furosemide B-Chemical - O - O importance O of O magnesium B-Chemical supplementation O . O Diuretics O may O induce O hypokalemia B-Disease , O hypocalcemia B-Disease and O hypomagnesemia B-Disease . O While O severe O hypokalemia B-Disease may O cause O muscle B-Disease weakness I-Disease , O severe O hypomagnesemia B-Disease is O associated O with O muscle B-Disease spasms I-Disease and O tetany B-Disease which O cannot O be O corrected O by O potassium B-Chemical and O calcium B-Chemical supplementation O alone O ( O 1 O , O 2 O ) O . O Surreptitious O diuretic O ingestion O has O been O described O , O mainly O in O women O who O are O concerned O that O they O are O obese B-Disease or O edematous B-Disease . O Symptomatic O hypokalemia B-Disease has O been O reported O in O such O patients O ( O 3 O - O 7 O ) O and O in O one O case O hypocalcemia B-Disease was O observed O ( O 8 O ) O , O but O the O effects O of O magnesium B-Chemical depletion O were O not O noted O in O these O patients O . O Ciprofloxacin B-Chemical - O induced O nephrotoxicity B-Disease in O patients O with O cancer B-Disease . O Nephrotoxicity B-Disease associated O with O ciprofloxacin B-Chemical is O uncommon O . O Five O patients O with O cancer B-Disease who O developed O acute B-Disease renal I-Disease failure I-Disease that O followed O treatment O with O ciprofloxacin B-Chemical are O described O and O an O additional O 15 O cases O reported O in O the O literature O are O reviewed O . O Other O than O elevation O of O serum O creatinine B-Chemical levels O , O characteristic O clinical O manifestations O and O abnormal O laboratory O findings O are O not O frequently O present O . O Allergic O interstitial B-Disease nephritis I-Disease is O believed O to O be O the O underlying O pathological O - O process O . O Definitive O diagnosis O requires O performance O of O renal O biopsy O , O although O this O is O not O always O feasible O . O An O improvement O in O renal O function O that O followed O the O discontinuation O of O the O offending O antibiotic O supports O the O presumptive O diagnosis O of O ciprofloxacin B-Chemical - O induced O acute B-Disease renal I-Disease failure I-Disease . O Venous B-Disease complications I-Disease of O midazolam B-Chemical versus O diazepam B-Chemical . O Although O some O studies O have O suggested O fewer O venous B-Disease complications I-Disease are O associated O with O midazolam B-Chemical than O with O diazepam B-Chemical for O endoscopic O procedures O , O this O variable O has O not O been O well O documented O . O We O prospectively O evaluated O the O incidence O of O venous B-Disease complications I-Disease after O intravenous O injection O of O diazepam B-Chemical or O midazolam B-Chemical in O 122 O consecutive O patients O undergoing O colonoscopy O and O esophagogastroduodenoscopy O . O Overall O , O venous B-Disease complications I-Disease were O more O frequent O with O diazepam B-Chemical ( O 22 O of O 62 O patients O ) O than O with O midazolam B-Chemical ( O 4 O of O 60 O patients O ) O ( O p O < O 0 O . O 001 O ) O . O A O palpable O venous O cord O was O present O in O 23 O % O ( O 14 O of O 62 O ) O of O patients O in O the O diazepam B-Chemical group O , O compared O with O 2 O % O ( O 1 O of O 60 O patients O ) O in O the O midazolam B-Chemical group O ( O p O < O 0 O . O 002 O ) O . O Pain B-Disease at O the O injection O site O occurred O in O 35 O % O ( O 22 O of O 62 O ) O of O patients O in O the O diazepam B-Chemical group O compared O with O 7 O % O ( O 4 O of O 60 O patients O ) O in O the O midazolam B-Chemical group O ( O p O < O 0 O .

O Changes O in O peroxisomes O in O preneoplastic O liver O and O hepatoma B-Disease of O mice O induced O by O alpha B-Chemical - I-Chemical benzene I-Chemical hexachloride I-Chemical . O Peroxisomes O in O hepatomas B-Disease and O hyperplastic O preneoplastic O liver B-Disease lesions I-Disease induced O in O mice O by O 500 O ppm O alpha B-Chemical - I-Chemical benzene I-Chemical hexachloride I-Chemical were O examined O histochemically O and O electron O microscopically O . O Although O most O of O the O hepatomas B-Disease were O well O - O differentiated O tumors B-Disease and O contained O a O considerable O number O of O peroxisomes O , O the O tumor B-Disease cells O did O not O respond O to O ethyl B-Chemical - I-Chemical alpha I-Chemical - I-Chemical p I-Chemical - I-Chemical chlorophenoxyisobutyrate I-Chemical with O proliferation O of O peroxisomes O . O At O the O 16th O week O of O carcinogen O feeding O , O hyperplastic O nodules O appeared O and O advanced O to O further O stages O .

O Contribution O of O the O sympathetic O nervous O system O to O salt O - O sensitivity O in O lifetime O captopril B-Chemical - O treated O spontaneously O hypertensive B-Disease rats O . O OBJECTIVE O : O To O test O the O hypothesis O that O , O in O lifetime O captopril B-Chemical - O treated O spontaneously O hypertensive B-Disease rats O ( O SHR O ) O , O the O sympathetic O nervous O system O contributes O importantly O to O the O hypertensive B-Disease effect O of O dietary B-Chemical sodium I-Chemical chloride I-Chemical supplementation O . O METHODS O : O Male O SHR O ( O aged O 6 O weeks O ) O that O had O been O treated O from O conception O onward O with O either O captopril B-Chemical or O vehicle O remained O on O a O basal O sodium B-Chemical chloride I-Chemical diet O or O were O fed O a O high O sodium B-Chemical chloride I-Chemical diet O . O After O 2 O weeks O , O the O rats O were O subjected O to O ganglionic O blockade O and O 2 O days O later O , O an O infusion O of O clonidine B-Chemical . O RESULTS O : O Lifetime O captopril B-Chemical treatment O significantly O lowered O mean O arterial O pressure O in O both O groups O . O Intravenous O infusion O of O the O ganglionic O blocker O hexamethonium B-Chemical resulted O in O a O rapid O decline O in O MAP O that O eliminated O the O dietary B-Chemical sodium I-Chemical chloride I-Chemical - O induced O increase B-Disease in I-Disease MAP I-Disease in O both O groups O . O Infusion O of O the O central O nervous O system O alpha2 B-Chemical - I-Chemical adrenergic I-Chemical receptor I-Chemical agonist I-Chemical clonidine B-Chemical also O resulted O in O a O greater O reduction O in O MAP O in O both O groups O of O SHR O that O were O fed O the O high O ( O compared O with O the O basal O ) O sodium B-Chemical chloride I-Chemical diet O . O CONCLUSIONS O : O In O both O lifetime O captopril B-Chemical - O treated O and O control O SHR O , O the O sympathetic O nervous O system O contributes O to O the O pressor O effects O of O a O high O sodium B-Chemical chloride I-Chemical diet O . O Angioedema B-Disease associated O with O droperidol B-Chemical administration O . O Angioedema B-Disease , O also O known O as O angioneurotic B-Disease edema I-Disease or O Quincke B-Disease ' I-Disease s I-Disease disease I-Disease , O is O a O well O - O demarcated O , O localized O edema B-Disease involving O the O subcutaneous O tissues O that O may O cause O upper B-Disease - I-Disease airway I-Disease obstruction I-Disease . O We O report O the O case O of O a O previously O healthy O 19 O - O year O - O old O man O with O no O known O drug B-Disease allergies I-Disease in O whom O angioedema B-Disease with O significant O tongue B-Disease swelling I-Disease and O protrusion O developed O within O 10 O minutes O of O the O administration O of O a O single O IV O dose O of O droperidol B-Chemical . O Late O cardiotoxicity B-Disease after O treatment O for O a O malignant O bone B-Disease tumor I-Disease . O Cardiac O function O was O assessed O in O long O - O term O survivors O of O malignant O bone B-Disease tumors I-Disease who O were O treated O according O to O Rosen B-Chemical ' I-Chemical s I-Chemical T5 I-Chemical or I-Chemical T10 I-Chemical protocol I-Chemical , O both O including O doxorubicin B-Chemical . O Thirty O - O one O patients O , O age O 10 O - O 45 O years O ( O median O age O 17 O . O 8 O years O ) O were O evaluated O 2 O . O 3 O - O 14 O . O 1 O years O ( O median O 8 O . O 9 O years O ) O following O completion O of O treatment O . O Cumulative O doses O of O doxorubicin B-Chemical were O 225 O - O 550 O mg O / O m2 O ( O median O dose O 360 O ) O . O The O evaluation O consisted O of O a O history O , O physical O examination O , O electrocardiogram O ( O ECG O ) O , O signal O averaged O ECG O , O 24 O - O hour O ambulatory O ECG O , O echocardiography O and O radionuclide O angiography O . O Eighteen O of O 31 O ( O 58 O % O ) O patients O showed O cardiac B-Disease toxicity I-Disease , O defined O as O having O one O or O more O of O the O following O abnormalities O : O late O potentials O , O complex O ventricular B-Disease arrhythmias I-Disease , O left O ventricular B-Disease dilation I-Disease , O decreased O shortening O fraction O , O or O decreased O ejection O fraction O . O The O incidence O of O cardiac B-Disease abnormalities I-Disease increased O with O length O of O follow O - O up O ( O P O < O or O = O . O 05 O ) O . O No O correlation O could O be O demonstrated O between O cumulative O dose O of O doxorubicin B-Chemical and O cardiac O status O , O except O for O heart O rate O variability O . O When O adjusted O to O body O surface O area O , O the O left O ventricular O posterior O wall O thickness O ( O LVPW O index O ) O was O decreased O in O all O patients O . O The O incidence O of O doxorubicin B-Chemical - O induced O cardiotoxicity B-Disease is O high O and O increases O with O follow O - O up O , O irrespective O of O cumulative O dose O . O Life O - O long O cardiac O follow O - O up O in O these O patients O is O warranted O . O The O results O of O our O study O suggest O that O heart O rate O variability O and O LVPW O index O could O be O sensitive O indicators O for O cardiotoxicity B-Disease . O Acute O blood O pressure O elevations O with O caffeine B-Chemical in O men O with O borderline O systemic O hypertension B-Disease . O Whether O the O vasoconstrictive O actions O of O caffeine B-Chemical are O enhanced O in O hypertensive B-Disease persons O has O not O been O demonstrated O . O Thus O , O caffeine B-Chemical ( O 3 O . O 3 O mg O / O kg O ) O versus O placebo O was O tested O in O 48 O healthy O men O ( O aged O 20 O to O 35 O years O ) O selected O after O screening O on O 2 O separate O occasions O . O Borderline O hypertensive B-Disease men O ( O n O = O 24 O ) O were O selected O with O screening O systolic O blood O pressure O ( O BP O ) O of O 140 O to O 160 O mm O Hg O and O / O or O diastolic O BP O 90 O to O 99 O mm O Hg O . O Low O - O risk O controls O ( O n O = O 24 O ) O reported O no O parental O history O of O hypertension B-Disease and O had O screening O BP O < O 130 O / O 85 O mm O Hg O . O Participants O were O then O tested O on O 2 O occasions O after O 12 O - O hour O abstinence O from O caffeine B-Chemical in O each O of O 2 O protocols O ; O this O required O a O total O of O 4 O laboratory O visits O . O Caffeine B-Chemical - O induced O changes O in O diastolic O BP O were O 2 O to O 3 O times O larger O in O borderline O subjects O than O in O controls O ( O + O 8 O . O 4 O vs O + O 3 O . O 8 O mm O Hg O , O p O < O 0 O . O 0001 O ) O , O and O were O attributable O to O larger O changes O in O impedance O - O derived O measures O of O systemic O vascular O resistance O ( O + O 135 O vs O + O 45 O dynes O . O s O . O cm O - O 5 O , O p O < O 0 O . O 004 O ) O . O These O findings O were O consistent O and O reached O significance O in O both O protocols O . O The O percentage O of O borderline O subjects O in O whom O diastolic O BP O changes O exceeded O the O median O control O response O was O 96 O % O . O Consequently O , O whereas O all O participants O exhibited O normotensive O levels O during O the O resting O predrug O baseline O , O 33 O % O of O borderline O subjects O achieved O hypertensive B-Disease BP O levels O after O caffeine B-Chemical ingestion O . O Thus O , O in O borderline O hypertensive B-Disease men O , O exaggerated O responses O to O caffeine B-Chemical were O : O selective O for O diastolic O BP O , O consistent O with O greater O vasoconstriction O , O replicated O in O 2 O protocols O , O and O representative O of O nearly O all O borderline O hypertensives B-Disease . O We O suspect O that O the O potential O for O caffeine B-Chemical to O stabilize O high O resistance O states O in O susceptible O persons O suggests O that O its O use O may O facilitate O their O disease O progression O , O as O well O as O hinder O accurate O diagnosis O and O treatment O . O Absence O of O effect O of O sertraline B-Chemical on O time O - O based O sensitization O of O cognitive B-Disease impairment I-Disease with O haloperidol B-Chemical . O This O double O - O blind O , O randomized O , O placebo O - O controlled O study O evaluated O the O effects O of O haloperidol B-Chemical alone O and O haloperidol B-Chemical plus O sertraline B-Chemical on O cognitive O and O psychomotor O function O in O 24 O healthy O male O subjects O . O METHOD O : O All O subjects O received O placebo O on O Day O 1 O and O haloperidol B-Chemical 2 O mg O on O Days O 2 O and O 25 O . O From O Days O 9 O to O 25 O , O subjects O were O randomly O assigned O to O either O sertraline B-Chemical ( O 12 O subjects O ) O or O placebo O ( O 12 O subjects O ) O ; O the O sertraline B-Chemical dose O was O titrated O from O 50 O to O 200 O mg O / O day O from O Days O 9 O to O 16 O , O and O remained O at O 200 O mg O / O day O for O the O final O 10 O days O of O the O drug O administration O period O . O Cognitive O function O testing O was O performed O before O dosing O and O over O a O 24 O - O hour O period O after O dosing O on O Days O 1 O , O 2 O , O and O 25 O . O RESULTS O : O Impairment B-Disease of I-Disease cognitive I-Disease function I-Disease was O observed O 6 O to O 8 O hours O after O administration O of O haloperidol B-Chemical on O Day O 2 O but O was O not O evident O 23 O hours O after O dosing O . O When O single O - O dose O haloperidol B-Chemical was O given O again O 25 O days O later O , O greater O impairment O with O earlier O onset O was O noted O in O several O tests O in O both O treatment O groups O , O suggesting O enhancement O of O this O effect O . O There O was O no O indication O that O sertraline B-Chemical exacerbated O the O impairment O produced O by O haloperidol B-Chemical since O an O equivalent O effect O also O occurred O in O the O placebo O group O . O Three O subjects O ( O 2 O on O sertraline B-Chemical and O 1 O on O placebo O ) O withdrew O from O the O study O because O of O side O effects O . O Ten O subjects O in O each O group O reported O side O effects O related O to O treatment O . O The O side O effect O profiles O of O sertraline B-Chemical and O of O placebo O were O similar O . O CONCLUSION O : O Haloperidol B-Chemical produced O a O clear O profile O of O cognitive B-Disease impairment I-Disease that O was O not O worsened O by O concomitant O sertraline B-Chemical administration O . O Coexistence O of O cerebral B-Disease venous I-Disease sinus I-Disease and I-Disease internal I-Disease carotid I-Disease artery I-Disease thrombosis I-Disease associated O with O exogenous O sex O hormones O . O A O case O report O . O A O forty O - O six O year O - O old O premenopausal O woman O developed O headache B-Disease , O nausea B-Disease and O vomiting B-Disease , O left O hemiparesis B-Disease and O seizure B-Disease two O days O after O parenteral O use O of O progesterone B-Chemical and O estradiol B-Chemical . O Diabetes B-Disease mellitus I-Disease ( O DM B-Disease ) O was O found O during O admission O . O Computed O tomography O showed O a O hemorrhagic B-Disease infarct I-Disease in O the O right O frontal O lobe O and O increased O density O in O the O superior O sagittal O sinus O ( O SSS O ) O . O Left O carotid O angiography O found O occlusion B-Disease of I-Disease the I-Disease left I-Disease internal I-Disease carotid I-Disease artery I-Disease ( O ICA O ) O . O Right O carotid O angiograms O failed O to O show O the O SSS O and O inferior O sagittal O sinus O , O suggestive O of O venous B-Disease sinus I-Disease thrombosis I-Disease . O Coexistence O of O the O cerebral B-Disease artery I-Disease and I-Disease the I-Disease venous I-Disease sinus I-Disease occlusion I-Disease has O been O described O infrequently O . O In O this O case O , O the O authors O postulate O that O the O use O of O estradiol B-Chemical and O progesterone B-Chemical and O the O underlying O DM B-Disease increased O vascular O thrombogenicity O , O which O provided O a O common O denominator O for O thrombosis B-Disease of I-Disease both I-Disease the I-Disease ICA I-Disease and I-Disease the I-Disease venous I-Disease sinus I-Disease . O Chemotherapy O of O advanced O inoperable O non B-Disease - I-Disease small I-Disease cell I-Disease lung I-Disease cancer I-Disease with O paclitaxel B-Chemical : O a O phase O II O trial O . O Paclitaxel B-Chemical ( O Taxol B-Chemical ; O Bristol O - O Myers O Squibb O Company O , O Princeton O , O NJ O ) O has O demonstrated O significant O antineoplastic O activity O against O different O tumor B-Disease types O , O notably O ovarian B-Disease and I-Disease breast I-Disease carcinoma I-Disease . O Two O phase O II O trials O of O 24 O - O hour O paclitaxel B-Chemical infusions O in O chemotherapy O - O naive O patients O with O stage O IIIB O or O IV O non B-Disease - I-Disease small I-Disease cell I-Disease lung I-Disease cancer I-Disease ( O NSCLC B-Disease ) O reported O response O rates O of O 21 O % O and O 24 O % O . O Leukopenia B-Disease was O dose O limiting O : O as O many O as O 62 O . O 5 O % O of O patients O experienced O grade O 4 O leukopenia B-Disease . O We O investigated O the O efficacy O and O toxicity B-Disease of O a O 3 O - O hour O paclitaxel B-Chemical infusion O in O a O phase O II O trial O in O patients O with O inoperable O stage O IIIB O or O IV O NSCLC B-Disease . O The O 58 O patients O treated O ( O 41 O men O and O 17 O women O ) O had O a O median O age O of O 59 O years O ( O age O range O , O 25 O to O 75 O ) O and O a O performance O status O of O 0 O through O 2 O . O Most O patients O ( O 72 O . O 4 O % O ) O had O stage O IV O NSCLC B-Disease . O Paclitaxel B-Chemical 225 O mg O / O m2 O was O infused O over O 3 O hours O every O 3 O weeks O with O standard O prophylactic O premedication O . O Of O 50 O patients O evaluable O for O response O , O 12 O ( O 24 O % O ) O had O partial O remission O , O 26 O ( O 52 O % O ) O had O no O change O , O and O 12 O had O disease O progression O ( O 24 O % O ) O . O Hematologic O toxicities B-Disease were O mild O : O only O one O patient O ( O 2 O % O ) O developed O grade O 3 O or O 4 O neutropenia B-Disease , O while O 29 O % O had O grade O 1 O or O 2 O . O Grade O 1 O or O 2 O polyneuropathy B-Disease affected O 56 O % O of O patients O while O only O one O ( O 2 O % O ) O experienced O severe O polyneuropathy B-Disease . O Similarly O , O grade O 1 O or O 2 O myalgia B-Disease / O arthralgia B-Disease was O observed O in O 63 O . O 2 O % O of O patients O , O but O only O 14 O . O 3 O % O experienced O grade O 3 O or O 4 O . O Nausea B-Disease and O vomiting B-Disease were O infrequent O , O with O 14 O % O of O patients O experiencing O grade O 1 O or O 2 O and O only O 2 O % O experiencing O grade O 3 O or O 4 O . O Paclitaxel B-Chemical is O thus O an O active O single O agent O in O this O patient O population O , O with O a O 3 O - O hour O infusion O proving O comparably O effective O to O a O 24 O - O hour O infusion O and O superior O in O terms O of O the O incidence O of O hematologic O and O nonhematologic O toxicity B-Disease . O Further O phase O II O studies O with O paclitaxel B-Chemical combined O with O other O drugs O active O against O NSCLC B-Disease are O indicated O , O and O phase O III O studies O comparing O paclitaxel B-Chemical with O standard O chemotherapy O remain O to O be O completed O . O Paclitaxel B-Chemical combined O with O carboplatin B-Chemical in O the O first O - O line O treatment O of O advanced O ovarian B-Disease cancer I-Disease . O In O a O phase O I O study O to O determine O the O maximum O tolerated O dose O of O paclitaxel B-Chemical ( O Taxol B-Chemical ; O Bristol O - O Myers O Squibb O Company O , O Princeton O , O NJ O ) O given O as O a O 3 O - O hour O infusion O in O combination O with O carboplatin B-Chemical administered O every O 21 O days O to O women O with O advanced O ovarian B-Disease cancer I-Disease , O paclitaxel B-Chemical doses O were O escalated O as O follows O : O level O 1 O , O 135 O mg O / O m2 O ; O level O 2 O , O 160 O mg O / O m2 O ; O level O 3 O , O 185 O mg O / O m2 O ; O and O level O 4 O , O 210 O mg O / O m2 O . O The O fixed O dose O of O carboplatin B-Chemical at O levels O 1 O through O 4 O was O given O to O achieve O an O area O under O the O concentration O - O time O curve O ( O AUC O ) O of O 5 O using O the O Calvert O formula O . O In O levels O 5 O and O 6 O the O carboplatin B-Chemical dose O was O targeted O at O AUCs O of O 6 O and O 7 O . O 5 O , O respectively O , O combined O with O a O fixed O paclitaxel B-Chemical dose O of O 185 O mg O / O m2 O . O To O date O , O 30 O previously O untreated O patients O , O all O with O a O good O performance O status O ( O Eastern O Cooperative O Oncology O Group O 0 O to O 2 O ) O have O been O entered O into O this O ongoing O study O . O The O dose O - O limiting O toxicity B-Disease of O the O combination O was O myelosuppression B-Disease ( O leukopenia B-Disease , O granulocytopenia B-Disease , O and O thrombocytopenia B-Disease ) O . O Neurotoxicity B-Disease was O largely O moderate O . O So O far O , O 14 O patients O are O evaluable O for O response O ; O of O these O , O eight O ( O 57 O % O ) O showed O objective O ( O complete O or O partial O ) O response O and O disease O stabilized O in O six O patients O . O No O patient O had O disease O progression O . O We O conclude O that O the O combination O of O paclitaxel B-Chemical 185 O mg O / O m2 O administered O as O a O 3 O - O hour O infusion O followed O immediately O by O a O 1 O - O hour O infusion O of O carboplatin B-Chemical at O an O AUC O of O 6 O can O be O administered O safely O in O a O 21 O - O day O schedule O in O the O outpatient O setting O . O The O recommended O dose O for O phase O III O studies O is O paclitaxel B-Chemical 185 O mg O / O m2 O and O carboplatin B-Chemical AUC O 6 O . O Effects O of O acute O steroid B-Chemical administration O on O ventilatory O and O peripheral O muscles O in O rats O . O Occasional O case O reports O have O shown O that O acute O myopathy B-Disease may O occur O in O patients O treated O with O massive O doses O of O corticosteroids B-Chemical . O The O mechanism O of O this O myopathy B-Disease is O poorly O understood O . O Therefore O , O 60 O male O rats O were O randomly O assigned O to O receive O daily O injection O of O saline O ( O C O ) O , O methylprednisolone B-Chemical ( O M B-Chemical ) O , O or O triamcinolone B-Chemical ( O T B-Chemical ) O 80 O mg O / O kg O / O d O for O 5 O d O . O Nutritional O intake O , O measured O daily O in O 15 O animals O , O showed O a O significant O reduction B-Disease of I-Disease food I-Disease intake I-Disease in O the O steroid B-Chemical - O treated O groups O ( O - O 50 O and O - O 79 O % O in O M B-Chemical and O T B-Chemical , O respectively O ) O . O This O was O associated O with O a O similar O loss B-Disease in I-Disease body I-Disease weight I-Disease . O In O the O 45 O remaining O animals O , O diaphragm O contractility O and O histopathologic O features O of O several O muscles O were O studied O . O Weights O of O respiratory O and O peripheral O muscles O were O similarly O decreased O after O steroid B-Chemical treatment O . O Maximal O twitches O of O the O diaphragm O were O lower O in O the O C O group O ( O 653 O + O / O - O 174 O g O / O cm O ( O 2 O ) O ) O than O in O the O M B-Chemical group O ( O 837 O + O / O - O 171 O g O / O cm O ( O 2 O ) O ; O p O < O 0 O . O 05 O ) O and O the O T B-Chemical group O ( O 765 O + O / O - O 145 O g O / O cm O ( O 2 O ) O , O NS O ) O . O Half O - O relaxation O time O was O prolonged O in O both O steroid B-Chemical groups O , O and O time O to O peak O tension O was O longer O with O M B-Chemical , O whereas O tetanic B-Disease tensions O were O similar O . O Steroid B-Chemical treatment O also O induced O a O leftward O shift O of O the O force O - O frequency O curve O at O 25 O and O 50 O Hz O when O compared O with O saline O treatment O ( O p O < O 0 O . O 05 O ) O . O ATPase O staining O of O the O diaphragm O , O scalenus O medius O , O and O gastrocnemius O showed O type O IIb O fiber O atrophy B-Disease in O the O steroid B-Chemical groups O and O also O diaphragmatic O type O IIa O atrophy B-Disease with O T B-Chemical , O whereas O histologic O examinations O revealed O a O normal O muscular O pattern O with O absence O of O necrosis B-Disease . O Finally O , O a O pair O - O fed O ( O PF O ) O study O , O performed O in O 18 O rats O ( O C O , O T B-Chemical , O and O PF O ) O , O showed O that O muscle B-Disease atrophy I-Disease was O considerably O less O pronounced O in O PF O animals O than O in O T B-Chemical - O treated O animals O . O We O conclude O that O ( O 1 O ) O short O - O term O treatment O with O massive O doses O of O steroids B-Chemical induced O severe O respiratory O and O limb O muscle O wasting O ; O ( O 2 O ) O both O types O of O steroids B-Chemical induced O predominantly O type O IIb O atrophy B-Disease , O resulting O in O the O expected O alterations O in O diaphragm O contractile O properties O ; O ( O 3 O ) O neither O steroid B-Chemical caused O muscle O necrosis B-Disease ; O ( O 4 O ) O type O IIb O atrophy B-Disease was O not O caused O by O acute O nutritional O deprivation O alone O . O Continuous O subcutaneous O administration O of O mesna B-Chemical to O prevent O ifosfamide B-Chemical - O induced O hemorrhagic B-Disease cystitis I-Disease . O Hemorrhagic B-Disease cystitis I-Disease is O a O major O potential O toxicity B-Disease of O ifosfamide B-Chemical that O can O be O prevented O by O administering O mesna B-Chemical along O with O the O cytotoxic O agent O . O Mesna B-Chemical is O generally O administered O by O the O intravenous O route O , O although O experience O with O oral O delivery O of O the O drug O has O increased O . O The O continuous O subcutaneous O administration O of O mesna B-Chemical has O the O advantage O of O not O requiring O intravenous O access O . O In O addition O , O subcutaneous O delivery O of O the O neutralizing O agent O will O not O be O associated O with O the O risk O of O inadequate O urinary O mesna B-Chemical concentrations O , O such O as O in O a O patient O taking O oral O mesna B-Chemical who O experiences O severe O ifosfamide B-Chemical - O induced O emesis B-Disease and O is O unable O to O absorb O the O drug O . O Limited O clinical O experience O with O continuous O subcutaneous O mesna B-Chemical administration O suggests O it O is O a O safe O , O practical O , O and O economic O method O of O drug O delivery O that O permits O ifosfamide B-Chemical to O be O administered O successfully O in O the O outpatient O setting O . O Leg B-Disease and I-Disease back I-Disease pain I-Disease after O spinal O anaesthesia O involving O hyperbaric O 5 O % O lignocaine B-Chemical .

O Five O of O the O 13 O patients O ( O 38 O % O ) O with O pain B-Disease and O seven O of O the O 41 O patients O ( O 17 O % O ) O without O pain B-Disease admitted O to O a O high O alcohol B-Chemical intake O , O which O might O be O a O contributing O factor O . O Leg B-Disease and I-Disease / I-Disease or I-Disease back I-Disease pain I-Disease is O associated O with O the O intrathecal O use O of O hyperbaric O 5 O % O lignocaine B-Chemical . O The O use O of O serum O cholinesterase O in O succinylcholine B-Chemical apnoea B-Disease . O Fifteen O patients O demonstrating O unexpected O prolonged O apnoea B-Disease lasting O several O hours O after O succinylcholine B-Chemical have O been O treated O by O a O new O preparation O of O human O serum O cholinesterase O . O Adequate O spontaneous O respiration O was O re O - O established O in O an O average O period O of O ten O minutes O after O the O injection O . O In O 12 O patients O biochemical O genetic O examinations O confirmed O the O presence O of O an O atypical O serum O cholinesterase O . O In O three O patients O none O of O the O usual O variants O were O found O . O It O is O therefore O supposed O that O other O unknown O variants O of O serum O cholinesterase O exist O which O cannot O hydrolyze O succinylcholine B-Chemical . O The O use O of O serum O cholinesterase O in O succinylcholine B-Chemical apnoea B-Disease provided O considerable O relief O to O both O patient O and O anaesthetist O . O Increased O sulfation O and O decreased O 7alpha O - O hydroxylation O of O deoxycholic B-Chemical acid I-Chemical in O ethinyl B-Chemical estradiol I-Chemical - O induced O cholestasis B-Disease in O rats O . O Deoxycholic B-Chemical acid I-Chemical conjugation O , O transport O capacity O , O and O metabolism O were O compared O in O control O and O ethinyl B-Chemical estradiol I-Chemical - O treated O rats O . O Control O rats O were O found O to O have O a O lower O capacity O to O transport O deoxycholic B-Chemical acid I-Chemical than O taurodeoxycholic B-Chemical acid I-Chemical , O and O both O were O decreased O by O ethinyl B-Chemical estradiol I-Chemical treatment O . O During O [ O 24 O - O 14C O ] O sodium B-Chemical deoxycholate I-Chemical infusion O , O [ O 14C O ] O biliary O bile B-Chemical acid I-Chemical secretion O increased O , O but O bile O flow O did O not O change O significantly O in O either O control O or O ethinyl B-Chemical estradiol I-Chemical - O treated O rats O . O Ethinyl B-Chemical estradiol I-Chemical - O treated O animals O excreted O significantly O less O 14C O as O taurocholic B-Chemical acid I-Chemical than O did O control O animals O , O consistent O with O an O impairment O of O 7alpha O - O hydroxylation O of O taurodeoxycholic B-Chemical acid I-Chemical . O Ethinyl B-Chemical estradiol I-Chemical treatment O did O not O impair O conjugation O of O deoxycholic B-Chemical acid I-Chemical , O but O did O result O in O an O increase O in O sulfation O of O taurodeoxycholic B-Chemical acid I-Chemical from O 1 O . O 5 O % O in O controls O to O nearly O 4 O . O 0 O % O ( O P O less O than O 0 O . O 01 O ) O . O These O results O are O consistent O with O the O hypothesis O that O the O rat O has O a O poorer O tolerance O for O deoxycholic B-Chemical acid I-Chemical than O do O certain O other O species O . O Furthermore O , O the O rat O converts O deoxycholic B-Chemical acid I-Chemical , O a O poor O choleretic O , O to O taurocholic B-Chemical acid I-Chemical , O a O good O choleretic O . O When O this O conversion O is O impaired O with O ethinyl B-Chemical estradiol I-Chemical treatment O , O sulfation O may O be O an O important O alternate O pathway O for O excretion O of O this O potentially O harmful O bile B-Chemical acid I-Chemical . O Influence O of O diet O free O of O NAD B-Chemical - O precursors O on O acetaminophen B-Chemical hepatotoxicity B-Disease in O mice O . O Recently O , O we O demonstrated O the O hepatoprotective O effects O of O nicotinic B-Chemical acid I-Chemical amide I-Chemical , O a O selective O inhibitor O of O poly B-Chemical ( I-Chemical ADP I-Chemical - I-Chemical ribose I-Chemical ) I-Chemical polymerase O ( O PARP O ; O EC O 2 O .

O The O present O study O investigates O the O effects O of O a O diet O free O of O precursors O of O NAD B-Chemical , O the O substrate O on O which O PARP O acts O , O in O female O NMRI O mice O with O AAP B-Chemical hepatitis B-Disease and O evaluates O the O influence O of O simultaneous O ethanol B-Chemical consumption O in O these O animals O . O Liver B-Disease injuries I-Disease were O quantified O as O serum O activities O of O glutamate B-Chemical - O oxaloacetate B-Chemical transaminase O ( O GOT O ) O and O glutamate B-Chemical - O pyruvate B-Chemical transaminase O ( O GPT O ) O . O While O AAP B-Chemical caused O a O 117 O - O fold O elevation O of O serum O transaminase O activities O in O mice O kept O on O a O standard O laboratory O diet O , O which O was O significantly O exacerbated O by O ethanol B-Chemical and O inhibited O by O nicotinic B-Chemical acid I-Chemical amide I-Chemical ( O NAA B-Chemical ) O , O adverse O effects O were O noted O in O animals O fed O a O diet O free O of O precursors O of O NAD B-Chemical . O In O these O animals O , O only O minor O increases O of O serum O transaminase O activities O were O measured O in O the O presence O of O AAP B-Chemical , O and O unlike O the O exacerbation O caused O by O ethanol B-Chemical in O mice O on O a O standard O diet O , O the O liver B-Disease damage I-Disease was O inhibited O by O 50 O % O by O ethanol B-Chemical . O A O further O 64 O % O reduction O of O hepatitis B-Disease was O observed O , O when O NAA B-Chemical was O given O to O ethanol B-Chemical / O AAP B-Chemical - O mice O . O Our O results O provide O evidence O that O the O AAP B-Chemical - O induced O hepatitis B-Disease and O its O exacerbation O by O ethanol B-Chemical can O either O be O reduced O by O end O - O product O inhibition O of O PARP O by O NAA B-Chemical or O by O dietary O depletion O of O the O enzyme O ' O s O substrate O NAD B-Chemical . O We O see O the O main O application O of O NAA B-Chemical as O for O the O combinational O use O in O pharmaceutical O preparations O of O acetaminophen B-Chemical in O order O to O avoid O hepatic B-Disease damage I-Disease in O patients O treated O with O this O widely O used O analgesic O . O Nightmares O and O hallucinations B-Disease after O long O - O term O intake O of O tramadol B-Chemical combined O with O antidepressants O . O Tramadol B-Chemical is O a O weak O opioid O with O effects O on O adrenergic O and O serotonergic O neurotransmission O that O is O used O to O treat O cancer B-Disease pain B-Disease and O chronic O non O malignant O pain B-Disease . O This O drug O was O initiated O in O association O with O paroxetine B-Chemical and O dosulepine B-Chemical hydrochloride I-Chemical in O a O tetraparetic B-Disease patient O with O chronic B-Disease pain I-Disease . O Fifty O - O six O days O after O initiation O of O the O treatment O the O patient O presented O hallucinations B-Disease that O only O stopped O after O the O withdrawal O of O psycho O - O active O drugs O and O tramadol B-Chemical . O The O case O report O questions O the O long O term O use O of O pain B-Disease killers O combined O with O psycho O - O active O drugs O in O chronic O non O malignant O pain B-Disease , O especially O if O pain B-Disease is O under O control O . O Effect O of O calcium B-Chemical chloride I-Chemical and O 4 B-Chemical - I-Chemical aminopyridine I-Chemical therapy O on O desipramine B-Chemical toxicity B-Disease in O rats O . O BACKGROUND O : O Hypotension B-Disease is O a O major O contributor O to O mortality O in O tricyclic O antidepressant O overdose B-Disease . O Recent O data O suggest O that O tricyclic O antidepressants O inhibit O calcium B-Chemical influx O in O some O tissues O . O This O study O addressed O the O potential O role O of O calcium B-Chemical channel O blockade O in O tricyclic O antidepressant O - O induced O hypotension B-Disease . O METHODS O : O Two O interventions O were O studied O that O have O been O shown O previously O to O improve O blood O pressure O with O calcium B-Chemical channel O blocker O overdose B-Disease . O CaCl2 B-Chemical and O 4 B-Chemical - I-Chemical aminopyridine I-Chemical . O Anesthetized O rats O received O the O tricyclic O antidepressant O desipramine B-Chemical IP O to O produce O hypotension B-Disease , O QRS O prolongation O , O and O bradycardia B-Disease . O Fifteen O min O later O , O animals O received O CaCl2 B-Chemical , O NaHCO3 B-Chemical , O or O saline O . O In O a O second O experiment O , O rats O received O tricyclic O antidepressant O desipramine B-Chemical IP O followed O in O 15 O min O by O 4 B-Chemical - I-Chemical aminopyridine I-Chemical or O saline O . O RESULTS O : O NaHCO3 B-Chemical briefly O ( O 5 O min O ) O reversed O hypotension B-Disease and O QRS O prolongation O . O CaCl2 B-Chemical and O 4 B-Chemical - I-Chemical aminopyridine I-Chemical failed O to O improve O blood O pressure O .

O 03 O ) O in O the O CaCl2 B-Chemical group O was O higher O than O the O other O groups O . O CONCLUSION O : O The O administration O of O CaCl2 B-Chemical or O 4 B-Chemical - I-Chemical aminopyridine I-Chemical did O not O reverse O tricyclic O antidepressant O - O induced O hypotension B-Disease in O rats O . O CaCl2 B-Chemical therapy O may O possibly O worsen O both O cardiovascular B-Disease and I-Disease central I-Disease nervous I-Disease system I-Disease toxicity I-Disease . O These O findings O do O not O support O a O role O for O calcium B-Chemical channel O inhibition O in O the O pathogenesis O of O tricyclic O antidepressant O - O induced O hypotension B-Disease . O Valsartan B-Chemical , O a O new O angiotensin B-Chemical II I-Chemical antagonist O for O the O treatment O of O essential O hypertension B-Disease : O a O comparative O study O of O the O efficacy O and O safety O against O amlodipine B-Chemical . O OBJECTIVE O : O To O compare O the O antihypertensive O efficacy O of O a O new O angiotensin B-Chemical II I-Chemical antagonist O , O valsartan B-Chemical , O with O a O reference O therapy O , O amlodipine B-Chemical . O METHODS O : O One O hundred O sixty O - O eight O adult O outpatients O with O mild O to O moderate O hypertension B-Disease were O randomly O allocated O in O double O - O blind O fashion O and O equal O number O to O receive O 80 O mg O valsartan B-Chemical or O 5 O mg O amlodipine B-Chemical for O 12 O weeks O . O After O 8 O weeks O of O therapy O , O in O patients O whose O blood O pressure O remained O uncontrolled O , O 5 O mg O amlodipine B-Chemical was O added O to O the O initial O therapy O . O Patients O were O assessed O at O 4 O , O 8 O , O and O 12 O weeks O . O The O primary O efficacy O variable O was O change O from O baseline O in O mean O sitting O diastolic O blood O pressure O at O 8 O weeks O . O Secondary O variables O included O change O in O sitting O systolic O blood O pressure O and O responder O rates O . O RESULTS O : O Both O valsartan B-Chemical and O amlodipine B-Chemical were O effective O at O lowering O blood O pressure O at O 4 O , O 8 O , O and O 12 O weeks O . O Similar O decreases O were O observed O in O both O groups O , O with O no O statistically O significant O differences O between O the O groups O for O any O variable O analyzed O . O For O the O primary O variable O the O difference O was O 0 O . O 5 O mm O Hg O in O favor O of O valsartan B-Chemical ( O p O = O 0 O . O 68 O ; O 95 O % O confidence O interval O , O - O 2 O . O 7 O to O 1 O . O 7 O ) O . O Responder O rates O at O 8 O weeks O were O 66 O . O 7 O % O for O valsartan B-Chemical and O 60 O . O 2 O % O for O amlodipine B-Chemical ( O p O = O 0 O .

O 3 O % O for O 10 O mg O amlodipine B-Chemical ) O . O CONCLUSIONS O : O The O data O show O that O valsartan B-Chemical is O at O least O as O effective O as O amlodipine B-Chemical in O the O treatment O of O mild O to O moderate O hypertension B-Disease . O The O results O also O show O valsartan B-Chemical to O be O well O tolerated O and O suggest O that O it O is O not O associated O with O side O effects O characteristic O of O this O comparator O class O , O dihydropyridine B-Chemical calcium B-Chemical antagonists O . O A O measure O of O pupillary B-Disease oscillation I-Disease as O a O marker O of O cocaine B-Chemical - O induced O paranoia B-Disease . O Cocaine B-Chemical - O induced O paranoia B-Disease ( O CIP B-Disease ) O remains O an O important O drug O - O induced O model O of O idiopathic O paranoia B-Disease for O which O no O psychophysiologic O marker O has O yet O emerged O . O Measures O of O pupillary B-Disease oscillation I-Disease were O able O to O significantly O distinguish O a O group O of O abstinent O crack B-Chemical cocaine I-Chemical abusers O endorsing O past O CIP B-Disease ( O n O = O 32 O ) O from O another O group O of O crack B-Chemical addicts O who O denied O past O CIP B-Disease ( O n O = O 29 O ) O . O Serotonin B-Disease syndrome I-Disease from O venlafaxine B-Chemical - O tranylcypromine B-Chemical interaction O . O Excessive O stimulation O of O serotonin B-Chemical 5HT1A O receptors O causes O a O syndrome O of O serotonin B-Chemical excess O that O consists O of O shivering O , O muscle B-Disease rigidity I-Disease , O salivation B-Disease , O confusion B-Disease , O agitation B-Disease and O hyperthermia B-Disease . O The O most O common O cause O of O this O syndrome O is O an O interaction O between O a O monoamine O oxidase O inhibitor O ( O MAOI O ) O and O a O specific O serotonin B-Chemical reuptake O inhibitor O . O Venlafaxine B-Chemical is O a O new O antidepressant O agent O that O inhibits O the O reuptake O of O serotonin B-Chemical and O norepinephrine B-Chemical . O We O report O a O venlafaxine B-Chemical - O MAOI O interaction O that O resulted O in O the O serotonin B-Disease syndrome I-Disease in O a O 23 O - O y O - O old O male O who O was O taking O tranylcypromine B-Chemical for O depression B-Disease . O He O had O been O well O until O the O morning O of O presentation O when O he O took O 1 O / O 2 O tab O of O venlafaxine B-Chemical . O Within O 2 O h O he O became O confused O with O jerking O movements O of O his O extremities O , O tremors B-Disease and O rigidity B-Disease . O He O was O brought O directly O to O a O hospital O where O he O was O found O to O be O agitated O and O confused O with O shivering O , O myoclonic B-Disease jerks I-Disease , O rigidity B-Disease , O salivation B-Disease and O diaphoresis O . O His O pupils O were O 7 O mm O and O sluggishly O reactive O to O light O . O Vital O signs O were O : O blood O pressure O 120 O / O 67 O mm O Hg O , O heart O rate O 127 O / O min O , O respiratory O rate O 28 O / O min O , O and O temperature O 97 O F O . O After O 180 O mg O of O diazepam B-Chemical i O . O v O . O he O remained O tremulous O with O muscle B-Disease rigidity I-Disease and O clenched O jaws O . O He O was O intubated O for O airway O protection O and O because O of O hypoventilation B-Disease , O and O was O paralyzed B-Disease to O control O muscle B-Disease rigidity I-Disease . O His O subsequent O course O was O remarkable O for O non O - O immune O thrombocytopenia B-Disease which O resolved O . O The O patient O ' O s O maximal O temperature O was O 101 O . O 2 O F O and O his O CPK O remained O < O 500 O units O / O L O with O no O other O evidence O of O rhabdomyolysis B-Disease . O His O mental O status O normalized O and O he O was O transferred O to O a O psychiatry O ward O . O This O patient O survived O without O sequelae O due O to O the O aggressive O sedation O and O neuromuscular O paralysis B-Disease . O Cyclophosphamide B-Chemical associated O bladder B-Disease cancer I-Disease - O - O a O highly O aggressive O disease O : O analysis O of O 12 O cases O . O PURPOSE O : O We O gained O knowledge O of O the O etiology O , O treatment O and O prevention O of O cyclophosphamide B-Chemical associated O urothelial B-Disease cancer I-Disease . O MATERIALS O AND O METHODS O : O The O medical O records O of O 6 O men O and O 6 O women O ( O mean O age O 55 O years O ) O with O cyclophosphamide B-Chemical associated O bladder B-Disease cancer I-Disease were O reviewed O . O RESULTS O : O All O tumors B-Disease were O grade O 3 O or O 4 O transitional O cell O carcinoma B-Disease . O Of O the O 5 O patients O initially O treated O with O endoscopic O resection O alone O only O 1 O is O alive O without O disease O . O Of O the O 6 O patients O who O underwent O early O cystectomy O 4 O were O alive O at O 24 O to O 111 O months O . O The O remaining O patient O with O extensive O cancer B-Disease underwent O partial O cystectomy O for O palliation O and O died O 3 O months O later O . O CONCLUSIONS O : O Cyclophosphamide B-Chemical associated O bladder B-Disease tumor I-Disease is O an O aggressive O disease O . O However O , O long O - O term O survival O is O possible O when O radical O cystectomy O is O performed O for O bladder B-Disease tumors I-Disease with O any O sign O of O invasion O and O for O recurrent O high O grade O disease O , O even O when O noninvasive O . O A O phase O I O clinical O study O of O the O antipurine B-Chemical antifolate O lometrexol B-Chemical ( O DDATHF B-Chemical ) O given O with O oral O folic B-Chemical acid I-Chemical . O Lometrexol B-Chemical is O an O antifolate O which O inhibits O glycinamide B-Chemical ribonucleotide I-Chemical formyltransferase O ( O GARFT O ) O , O an O enzyme O essential O for O de O novo O purine B-Chemical synthesis O . O Extensive O experimental O and O limited O clinical O data O have O shown O that O lometrexol B-Chemical has O activity O against O tumours B-Disease which O are O refractory O to O other O drugs O , O notably O methotrexate B-Chemical . O However O , O the O initial O clinical O development O of O lometrexol B-Chemical was O curtailed O because O of O severe O and O cumulative O antiproliferative O toxicities B-Disease . O Preclinical O murine O studies O demonstrated O that O the O toxicity B-Disease of O lometrexol B-Chemical can O be O prevented O by O low O dose O folic B-Chemical acid I-Chemical administration O , O i O . O e O . O for O 7 O days O prior O to O and O 7 O days O following O a O single O bolus O dose O . O This O observation O prompted O a O Phase O I O clinical O study O of O lometrexol B-Chemical given O with O folic B-Chemical acid I-Chemical supplementation O which O has O confirmed O that O the O toxicity B-Disease of O lometrexol B-Chemical can O be O markedly O reduced O by O folic B-Chemical acid I-Chemical supplementation O . O Thrombocytopenia B-Disease and O mucositis B-Disease were O the O major O toxicities B-Disease . O There O was O no O clear O relationship O between O clinical O toxicity B-Disease and O the O extent O of O plasma O folate B-Chemical elevation O . O Associated O studies O demonstrated O that O lometrexol B-Chemical plasma O pharmacokinetics O were O not O altered O by O folic B-Chemical acid I-Chemical administration O indicating O that O supplementation O is O unlikely O to O reduce O toxicity B-Disease by O enhancing O lometrexol B-Chemical plasma O clearance O . O The O work O described O in O this O report O has O identified O for O the O first O time O a O clinically O acceptable O schedule O for O the O administration O of O a O GARFT O inhibitor O . O This O information O will O facilitate O the O future O evaluation O of O this O class O of O compounds O in O cancer B-Disease therapy O . O Fatal O excited O delirium B-Disease following O cocaine B-Chemical use O : O epidemiologic O findings O provide O new O evidence O for O mechanisms O of O cocaine B-Chemical toxicity B-Disease . O We O describe O an O outbreak O of O deaths O from O cocaine B-Chemical - O induced O excited O delirium B-Disease ( O EDDs B-Disease ) O in O Dade O County O , O Florida O between O 1979 O and O 1990 O . O From O a O registry O of O all O cocaine B-Chemical - O related O deaths O in O Dade O County O , O Florida O , O from O 1969 O - O 1990 O , O 58 O EDDs B-Disease were O compared O with O 125 O victims O of O accidental O cocaine B-Chemical overdose B-Disease without O excited O delirium B-Disease . O Compared O with O controls O , O EDDs B-Disease were O more O frequently O black O , O male O , O and O younger O . O They O were O less O likely O to O have O a O low O body O mass O index O , O and O more O likely O to O have O died O in O police O custody O , O to O have O received O medical O treatment O immediately O before O death O , O to O have O survived O for O a O longer O period O , O to O have O developed O hyperthermia B-Disease , O and O to O have O died O in O summer O months O . O EDDs B-Disease had O concentrations O of O cocaine B-Chemical and O benzoylecgonine B-Chemical in O autopsy O blood O that O were O similar O to O those O for O controls O . O The O epidemiologic O findings O are O most O consistent O with O the O hypothesis O that O chronic O cocaine B-Chemical use O disrupts O dopaminergic O function O and O , O when O coupled O with O recent O cocaine B-Chemical use O , O may O precipitate O agitation B-Disease , O delirium B-Disease , O aberrant O thermoregulation O , O rhabdomyolysis B-Disease , O and O sudden B-Disease death I-Disease . O Pemoline B-Chemical induced O acute O choreoathetosis B-Disease : O case O report O and O review O of O the O literature O . O BACKGROUND O : O Pemoline B-Chemical is O an O oxazolidine B-Chemical derivative O that O is O structurally O different O from O amphetamines B-Chemical and O used O in O the O treatment O of O attention B-Disease deficit I-Disease disorder I-Disease . O Pemoline B-Chemical has O not O been O commonly O associated O in O the O literature O as O a O cause O of O acute O movement B-Disease disorders I-Disease . O The O following O case O describes O two O children O acutely O poisoned O with O pemoline B-Chemical who O experienced O profound O choreoathetosis B-Disease . O CASE O REPORT O : O Two O , O 3 O - O year O - O old O male O , O identical O twin O siblings O presented O to O the O emergency O department O after O found O playing O with O a O an O empty O bottle O of O pemoline B-Chemical originally O containing O 59 O tablets O . O The O children O had O a O medical O history O significant O for O attention B-Disease deficit I-Disease disorder I-Disease previously O treated O with O methylphenidate B-Chemical without O success O . O This O was O their O first O day O of O pemoline B-Chemical therapy O . O The O choreoathetoid B-Disease movements O began O 45 O min O to O 1 O h O after O ingestion O . O The O children O gave O no O history O of O prior O movement B-Disease disorders I-Disease and O there O was O no O family O history O of O movement B-Disease disorders I-Disease . O The O children O received O gastrointestinal O decontamination O and O high O doses O of O intravenous O benzodiazepines B-Chemical in O an O attempt O to O control O the O choreoathetoid B-Disease movements O . O Despite O treatment O , O the O children O continued O to O have O choreoathetosis B-Disease for O approximately O 24 O hours O . O Forty O - O eight O hours O after O admission O , O the O children O appeared O to O be O at O their O baseline O and O were O discharged O home O . O CONCLUSION O : O Pemoline B-Chemical associated O movement B-Disease disorder I-Disease has O been O rarely O reported O in O the O acute O toxicology O literature O . O The O possibility O of O choreoathetoid B-Disease movements O should O be O considered O in O patients O presenting O after O pemoline B-Chemical overdose B-Disease . O Effect O of O myopic O excimer O laser O photorefractive O keratectomy O on O the O electrophysiologic O function O of O the O retina O and O optic O nerve O . O PURPOSE O : O To O assess O by O electrophysiologic O testing O the O effect O of O photorefractive O keratectomy O ( O PRK O ) O on O the O retina O and O optic O nerve O . O SETTING O : O Eye O Clinic O , O S O . O Salvatore O Hospital O , O L O ' O Aquila O University O , O Italy O . O METHODS O : O Standard O pattern O electroretinograms O ( O P O - O ERGs O ) O and O standard O pattern O visual O evoked O potentials O ( O P O - O VEPs O ) O were O done O in O 25 O eyes O of O 25 O patients O who O had O myopic O PRK O for O an O attempted O correction O between O 5 O . O 00 O and O 15 O . O 00 O diopters O ( O D O ) O ( O mean O 8 O . O 00 O D O ) O . O Testing O was O done O preoperatively O and O 3 O , O 6 O , O 12 O , O and O 18 O months O postoperatively O . O The O contralateral O eyes O served O as O controls O . O During O the O follow O - O up O , O 3 O patients O ( O 12 O % O ) O developed O steroid B-Chemical - O induced O elevated B-Disease intraocular I-Disease pressure I-Disease ( O IOP O ) O that O resolved O after O corticosteroid B-Chemical therapy O was O discontinued O . O RESULTS O : O No O statistically O significant O differences O were O seen O between O treated O and O control O eyes O nor O between O treated O eyes O preoperatively O and O postoperatively O . O CONCLUSION O : O Myopic O excimer O laser O PRK O did O not O seem O to O affect O the O posterior O segment O . O The O transient O steroid B-Chemical - O induced O IOP B-Disease rise I-Disease did O not O seem O to O cause O functional O impairment O . O Neutrophil O superoxide B-Chemical and O hydrogen B-Chemical peroxide I-Chemical production O in O patients O with O acute B-Disease liver I-Disease failure I-Disease . O Defects O in O superoxide B-Chemical and O hydrogen B-Chemical peroxide I-Chemical production O may O be O implicated O in O the O high O incidence O of O bacterial B-Disease infections I-Disease in O patients O with O acute B-Disease liver I-Disease failure I-Disease ( O ALF B-Disease ) O . O In O the O present O study O , O oxygen B-Chemical radical O production O in O patients O with O ALF B-Disease due O to O paracetamol B-Chemical overdose B-Disease was O compared O with O that O of O healthy O volunteers O . O Neutrophils O from O 14 O ALF B-Disease patients O were O stimulated O via O the O complement O receptors O using O zymosan O opsonized O with O ALF B-Disease or O control O serum O .

O In O addition O to O its O use O as O a O stabilizer O / O rigidifier O of O membranes O , O cholesteryl B-Chemical hemisuccinate I-Chemical , O tris B-Chemical salt I-Chemical ( O CS B-Chemical ) O administration O has O also O been O shown O to O protect O rats O from O the O hepatotoxic B-Disease effects O of O carbon B-Chemical tetrachloride I-Chemical ( O CCl4 B-Chemical ) O . O To O further O our O understanding O of O the O mechanism O of O CS B-Chemical cytoprotection O , O we O examined O in O rats O and O mice O the O protective O abilities O of O CS B-Chemical and O the O non O - O hydrolyzable O ether O form O of O CS B-Chemical , O gamma B-Chemical - I-Chemical cholesteryloxybutyric I-Chemical acid I-Chemical , O tris B-Chemical salt I-Chemical ( O CSE B-Chemical ) O against O acetaminophen B-Chemical - O , O adriamycin B-Chemical - O , O carbon B-Chemical tetrachloride I-Chemical - O , O chloroform B-Chemical - O and O galactosamine B-Chemical - O induced O toxicity B-Disease . O The O results O of O these O studies O demonstrated O that O CS B-Chemical - O mediated O protection O is O not O selective O for O a O particular O species O , O organ O system O or O toxic O chemical O .

O A O murine O model O of O adenomyosis B-Disease : O the O effects O of O hyperprolactinemia B-Disease induced O by O fluoxetine B-Chemical hydrochloride I-Chemical , O a O selective O serotonin B-Chemical reuptake O inhibitor O , O on O adenomyosis B-Disease induction O in O Wistar O albino O rats O . O OBJECTIVE O : O The O aim O of O this O study O was O to O investigate O whether O fluoxetine B-Chemical given O to O castrated O and O noncastrated O rats O caused O hyperprolactinemia B-Disease and O its O effects O with O respect O to O adenomyosis B-Disease . O DESIGN O : O Fluoxetine B-Chemical , O a O serotonin B-Chemical reuptake O inhibitor O , O was O given O to O Wistar O Albino O rats O for O 98 O days O to O produce O hyperprolactinemia B-Disease . O The O drug O was O given O to O two O groups O consisting O of O castrated O and O noncastrated O rats O and O compared O to O two O groups O of O castrated O and O noncastrated O controls O . O Prolactin O levels O were O measured O and O the O uteri O of O the O rats O were O removed O for O histopathological O analysis O at O the O end O of O 98 O days O . O SETTING O : O Marmara O University O School O of O Medicine O , O Department O of O Histology O and O Embryology O , O Zeynep O Kamil O Women O and O Children O ' O s O Hospital O . O MAIN O OUTCOME O MEASURES O : O Serum O prolactin O levels O , O uterine O histopathology O . O RESULTS O : O The O prolactin O levels O of O castrated O and O noncastrated O groups O treated O with O fluoxetine B-Chemical were O statistically O significantly O higher O when O compared O to O their O respective O control O groups O . O Histological O studies O revealed O 11 O cases O of O adenomyosis B-Disease , O all O within O the O noncastrated O group O receiving O fluoxetine B-Chemical . O CONCLUSION O : O It O was O suggested O that O high O serum O prolactin O levels O cause O degeneration O of O myometrial O cells O in O the O presence O of O ovarian O steroids B-Chemical that O results O in O a O myometrial O invasion O by O endometrial O stroma O . O This O invasion O eventually O progresses O to O adenomyosis B-Disease . O Postinfarction O ventricular B-Disease septal I-Disease defect I-Disease associated O with O long O - O term O steroid B-Chemical therapy O . O Two O cases O of O postinfarction O ventricular B-Disease septal I-Disease rupture I-Disease in O patients O on O long O - O term O steroid B-Chemical therapy O are O presented O and O the O favourable O outcome O in O both O cases O described O . O A O possible O association O between O steroid B-Chemical therapy O and O subsequent O postinfarction O septal B-Disease rupture I-Disease is O discussed O . O Neuroactive O steroids B-Chemical protect O against O pilocarpine B-Chemical - O and O kainic B-Chemical acid I-Chemical - O induced O limbic O seizures B-Disease and O status B-Disease epilepticus I-Disease in O mice O . O Several O structurally O related O metabolites O of O progesterone B-Chemical ( O 3 B-Chemical alpha I-Chemical - I-Chemical hydroxy I-Chemical pregnane I-Chemical - I-Chemical 20 I-Chemical - I-Chemical ones I-Chemical ) O and O deoxycorticosterone B-Chemical ( O 3 B-Chemical alpha I-Chemical - I-Chemical hydroxy I-Chemical pregnane I-Chemical - I-Chemical 21 I-Chemical - I-Chemical diol I-Chemical - I-Chemical 20 I-Chemical - I-Chemical ones I-Chemical ) O and O their O 3 O beta O - O epimers O were O evaluated O for O protective O activity O against O pilocarpine B-Chemical - O , O kainic B-Chemical acid I-Chemical - O and O N B-Chemical - I-Chemical methyl I-Chemical - I-Chemical D I-Chemical - I-Chemical aspartate I-Chemical ( O NMDA B-Chemical ) O - O induced O seizures B-Disease in O mice O . O Steroids B-Chemical with O the O 3 O - O hydroxy O group O in O the O alpha O - O position O and O 5 O - O H O in O the O alpha O - O or O beta O - O configurations O were O highly O effective O in O protecting O against O pilocarpine B-Chemical ( O 416 O mg O / O kg O , O s O .

O 8 O - O 63 O . O 5 O , O i O . O p O . O ) O . O Although O the O neuroactive O steroids B-Chemical were O considerably O less O potent O than O the O benzodiazepine B-Chemical clonazepam B-Chemical in O protecting O against O pilocarpine B-Chemical seizures B-Disease , O steroids B-Chemical with O the O 5 O alpha O , O 3 O alpha O - O configuration O had O comparable O or O higher O protective O index O values O ( O TD50 O for O motor O impairment O divided O by O ED50 O for O seizure B-Disease protection O ) O than O clonazepam B-Chemical , O indicating O that O some O neuroactive O steroids B-Chemical may O have O lower O relative O toxicity B-Disease . O Steroids B-Chemical with O the O 5 O alpha O , O 3 O alpha O - O or O 5 O beta O , O 3 O alpha O - O configurations O also O produced O a O dose O - O dependent O delay O in O the O onset O of O limbic O seizures B-Disease induced O by O kainic B-Chemical acid I-Chemical ( O 32 O mg O / O kg O , O s O . O c O . O ) O , O but O did O not O completely O protect O against O the O seizures B-Disease . O However O , O when O a O second O dose O of O the O steroid B-Chemical was O administered O 1 O hr O after O the O first O dose O , O complete O protection O from O the O kainic B-Chemical acid I-Chemical - O induced O limbic O seizures B-Disease and O status B-Disease epilepticus I-Disease was O obtained O . O The O steroids B-Chemical also O caused O a O dose O - O dependent O delay O in O NMDA B-Chemical ( O 257 O mg O / O kg O , O s O . O c O . O ) O - O induced O lethality O , O but O did O not O completely O protect O against O NMDA B-Chemical seizures B-Disease or O lethality O . O We O conclude O that O neuroactive O steroids B-Chemical are O highly O effective O in O protecting O against O pilocarpine B-Chemical - O and O kainic B-Chemical acid I-Chemical - O induced O seizures B-Disease and O status B-Disease epilepticus I-Disease in O mice O , O and O may O be O of O utility O in O the O treatment O of O some O forms O of O status B-Disease epilepticus I-Disease in O humans O . O Hepatic O and O extrahepatic O angiotensinogen O gene O expression O in O rats O with O acute O nephrotic B-Disease syndrome I-Disease . O Plasma O concentration O and O urine O excretion O of O the O renin O - O angiotensin B-Chemical system O proteins O are O altered O in O rats O with O nephrotic B-Disease syndrome I-Disease ( O NS B-Disease ) O . O In O this O work O the O messenger O ribonucleic O acid O ( O mRNA O ) O levels O of O angiotensinogen O ( O Ao O ) O were O analyzed O with O the O slot O - O blot O hybridization O technique O in O liver O and O other O extrahepatic O tissues O : O kidney O , O heart O , O brain O , O and O adrenal O gland O from O control O , O nephrotic B-Disease , O and O pair O - O fed O ( O PF O ) O rats O . O NS B-Disease was O induced O by O a O single O injection O of O puromycin B-Chemical amino I-Chemical - I-Chemical nucleoside I-Chemical ( O PAN B-Chemical ) O . O Although O a O great O urinary O excretion O and O half O - O normal O plasma O levels O of O Ao O were O observed O on O day O 6 O after O PAN B-Chemical injection O , O when O NS B-Disease was O clearly O established O , O hepatic O Ao O mRNA O levels O did O not O change O . O Furthermore O , O the O Ao O mRNA O levels O did O not O change O in O any O of O the O extrahepatic O tissues O studied O on O day O 6 O , O nor O did O its O hepatic O levels O at O days O 1 O , O 3 O , O 5 O , O or O 7 O after O PAN B-Chemical injection O . O These O data O suggest O that O the O hepatic O and O extrahepatic O Ao O mRNA O levels O are O unaltered O during O the O development O of O the O acute O NS B-Disease induced O by O PAN B-Chemical . O Neuroleptic B-Disease malignant I-Disease syndrome I-Disease with O risperidone B-Chemical . O Neuroleptic B-Disease malignant I-Disease syndrome I-Disease is O thought O to O be O a O result O of O dopamine B-Chemical D2 O receptor O blockade O in O the O striatum O of O the O basal O ganglia O . O Risperidone B-Chemical , O a O benzisoxazole B-Chemical derivative O antipsychotic O , O has O high O serotonin B-Chemical 5 O - O HT2 O receptor O blockade O and O dose O - O related O D2 O receptor O blockade O . O The O high O ratio O is O believed O to O impart O the O low O frequency O of O extrapyramidal B-Disease symptoms I-Disease with O risperidone B-Chemical at O low O dosages O . O With O this O low O frequency O of O extrapyramidal B-Disease symptoms I-Disease , O it O was O thought O the O frequency O of O neuroleptic B-Disease malignant I-Disease syndrome I-Disease might O also O be O lowered O . O A O 73 O - O year O - O old O woman O developed O neuroleptic B-Disease malignant I-Disease syndrome I-Disease after O monotherapy O with O risperidone B-Chemical . O The O syndrome O reversed O after O discontinuing O risperidone B-Chemical and O starting O treatment O with O dantrolene B-Chemical and O bromocriptine B-Chemical . O It O appears O that O the O protection O from O extrapyramidal O side O effects O observed O with O risperidone B-Chemical does O not O ensure O protection O from O neuroleptic B-Disease malignant I-Disease syndrome I-Disease . O The O attenuating O effect O of O carteolol B-Chemical hydrochloride I-Chemical , O a O beta O - O adrenoceptor O antagonist O , O on O neuroleptic O - O induced O catalepsy B-Disease in O rats O . O It O is O known O that O beta O - O adrenoceptor O antagonists O are O effective O in O the O treatment O of O akathisia B-Disease , O one O of O the O extrapyramidal O side O effects O that O occur O during O neuroleptic O treatment O . O Neuroleptic O - O induced O catalepsy B-Disease , O a O model O of O neuroleptic O - O induced O extrapyramidal O side O effects O , O was O considered O suitable O as O a O model O for O predicting O neuroleptic O - O induced O akathisia B-Disease in O humans O , O although O neuroleptic O - O induced O catalepsy B-Disease was O not O considered O a O specific O test O for O neuroleptic O - O induced O akathisia B-Disease . O Therefore O , O the O effects O of O carteolol B-Chemical , O a O beta O - O adrenoceptor O antagonist O , O on O haloperidol B-Chemical - O induced O catalepsy B-Disease in O rats O were O behaviorally O studied O and O compared O with O those O of O propranolol B-Chemical and O biperiden B-Chemical , O a O muscarinic O receptor O antagonist O . O Carteolol B-Chemical , O as O well O as O propranolol B-Chemical and O biperiden B-Chemical , O inhibited O the O haloperidol B-Chemical - O induced O catalepsy B-Disease . O The O inhibitory O effect O of O carteolol B-Chemical was O almost O comparable O to O that O of O propranolol B-Chemical , O but O was O weaker O than O that O of O biperiden B-Chemical . O Carteolol B-Chemical did O not O evoke O postsynaptic O dopamine B-Chemical receptor O - O stimulating O behavioral O signs O such O as O stereotypy O and O hyperlocomotion B-Disease in O rats O . O Carteolol B-Chemical did O not O antagonize O the O inhibitory O effects O of O haloperidol B-Chemical on O apomorphine B-Chemical - O induced O stereotypy O and O locomotor O activity O in O rats O . O In O addition O , O carteolol B-Chemical did O not O evoke O 5 O - O HT1A O receptor O - O stimulating O behavioral O signs O such O as O flat O body O posture O and O forepaw O treading O and O did O not O inhibit O 5 B-Chemical - I-Chemical hydroxytryptophan I-Chemical - O induced O head O twitch O in O rats O . O Finally O , O carteolol B-Chemical did O not O inhibit O physostigmine B-Chemical - O induced O lethality O in O rats O . O These O results O strongly O suggest O that O carteolol B-Chemical improves O haloperidol B-Chemical - O induced O catalepsy B-Disease via O its O beta O - O adrenoceptor O antagonistic O activity O and O is O expected O to O be O effective O in O the O treatment O of O akathisia B-Disease without O attenuating O neuroleptic O - O induced O antipsychotic O effects O due O to O its O postsynaptic O dopamine B-Chemical receptor O antagonistic O activity O . O Granulosa B-Disease cell I-Disease tumor I-Disease of I-Disease the I-Disease ovary I-Disease associated O with O antecedent O tamoxifen B-Chemical use O . O BACKGROUND O : O Increased O attention O has O been O focused O recently O on O the O estrogenic O effects O of O tamoxifen B-Chemical . O Review O of O the O literature O reveals O an O association O between O tamoxifen B-Chemical use O and O gynecologic O tumors B-Disease . O CASE O : O A O 52 O - O year O - O old O postmenopausal O woman O was O treated O with O tamoxifen B-Chemical for O stage O II O estrogen B-Chemical receptor O - O positive O breast B-Disease carcinoma I-Disease . O Her O aspartate B-Chemical transaminase O and O alanine B-Chemical transaminase O levels O increase O markedly O after O 6 O months O of O tamoxifen B-Chemical use O . O After O an O additional O 17 O months O of O elevated O serum O transaminases O , O the O patient O was O found O to O have O a O stage O Ic O granulosa B-Disease cell I-Disease tumor I-Disease of I-Disease the I-Disease ovary I-Disease . O CONCLUSION O : O Patients O with O tamoxifen B-Chemical - O induced O liver B-Disease dysfunction I-Disease may O be O at O increased O risk O for O granulosa B-Disease cell I-Disease tumors I-Disease because O of O alterations O in O tamoxifen B-Chemical metabolism O . O Lifetime O treatment O of O mice O with O azidothymidine B-Chemical ( O AZT B-Chemical ) O produces O myelodysplasia B-Disease . O AZT B-Chemical has O induced O a O macrocytic B-Disease anemia I-Disease in O AIDS B-Disease patients O on O long O term O AZT B-Chemical therapy O . O It O is O generally O assumed O that O DNA O elongation O is O stopped O by O the O insertion O of O AZT B-Chemical into O the O chain O in O place O of O thymidine B-Chemical thus O preventing O the O phosphate B-Chemical hydroxyl O linkages O and O therefore O suppresses O hemopoietic O progenitor O cell O proliferation O in O an O early O stage O of O differentiation O . O CBA O / O Ca O male O mice O started O on O AZT B-Chemical 0 O . O 75 O mg O / O ml O H2O O at O 84 O days O of O age O and O kept O on O it O for O 687 O days O when O dosage O reduced O to O 0 O . O 5 O mg O / O ml O H2O O for O a O group O , O another O group O removed O from O AZT B-Chemical to O see O recovery O , O and O third O group O remained O on O 0 O . O 75 O mg O . O At O 687 O days O mice O that O had O been O on O 0 O . O 75 O mg O had O average O platelet O counts O of O 2 O . O 5 O x O 10 O ( O 6 O ) O . O Histological O examination O on O 9 O of O 10 O mice O with O such O thrombocytopenia B-Disease showed O changes O compatible O with O myelodysplastic B-Disease syndrome I-Disease ( O MDS B-Disease ) O . O A O variety O of O histological O patterns O was O observed O . O There O were O two O cases O of O hypocellular O myelodysplasia B-Disease , O two O cases O of O hypersegmented O myelodysplastic B-Disease granulocytosis O , O two O cases O of O hypercellular O marrow O with O abnormal O megakaryocytes O with O bizarre O nuclei O , O one O case O of O megakaryocytic O myelosis O associated O with O a O hyperplastic B-Disease marrow I-Disease , O dysmyelopoiesis B-Disease and O a O hypocellular B-Disease marrow I-Disease and O two O cases O of O myelodysplasia B-Disease with O dyserythropoiesis B-Disease , O hemosiderosis B-Disease and O a O hypocellular B-Disease marrow I-Disease . O Above O mentioned O AZT B-Chemical incorporation O may O have O induced O an O ineffective O hemopoiesis O in O the O primitive O hemopoietic O progenitor O cells O , O which O is O known O to O be O seen O commonly O in O the O myelodysplastic B-Disease syndrome I-Disease . O Biphasic O response O of O the O SA O node O of O the O dog O heart O in O vivo O to O selective O administration O of O ketamine B-Chemical . O Effect O of O ketamine B-Chemical on O the O SA O node O of O the O dog O heart O was O studied O in O vivo O using O a O selective O perfusion O technique O of O the O SA O node O artery O . O Injections O of O ketamine B-Chemical in O doses O from O 100 O microgram O to O 3 O mg O into O the O artery O produced O a O depression B-Disease of O the O SA O nodal O activity O by O a O direct O action O . O This O depression B-Disease was O followed O by O the O sudden O appearance O of O a O stimulatory O phase O . O Bilateral O vagotomy O and O sympathectomy O or O prior O administration O of O a O ganglion O blocker O failed O to O inhibit O the O occurrence O of O the O ketamine B-Chemical - O induced O tachycardia B-Disease , O while O it O was O completely O abolished O in O the O reserpinized O dogs O or O by O a O prior O injection O of O a O beta O - O blocking O agent O into O the O SA O node O artery O . O This O may O indicate O that O an O activation O of O the O peripheral O adrenergic O mechanism O plays O an O important O role O in O the O induction O of O the O excitatory O effect O of O ketamine B-Chemical injected O in O the O SA O node O artery O . O Over O expression O of O vascular O endothelial O growth O factor O and O its O receptor O during O the O development O of O estrogen B-Chemical - O induced O rat O pituitary B-Disease tumors I-Disease may O mediate O estrogen B-Chemical - O initiated O tumor B-Disease angiogenesis O . O Estrogens B-Chemical , O which O have O been O associated O with O several O types O of O human O and O animal O cancers B-Disease , O can O induce O tumor B-Disease angiogenesis O in O the O pituitary O of O Fischer O 344 O rats O . O The O mechanistic O details O of O tumor B-Disease angiogenesis O induction O , O during O estrogen B-Chemical carcinogenesis B-Disease , O are O still O unknown O . O To O elucidate O the O role O of O estrogen B-Chemical in O the O regulation O of O tumor B-Disease angiogenesis O in O the O pituitary O of O female O rats O , O the O density O of O blood O vessels O was O analysed O using O factor O VIII O related O antigen O ( O FVIIIRAg O ) O immunohistochemistry O and O the O expression O of O vascular O endothelial O growth O factor O / O vascular O permeability O factor O ( O VEGF O / O VPF O ) O was O examined O by O Western O blot O and O immunohistochemical O analysis O . O The O expression O of O VEGF O receptor O ( O VEGFR O - O 2 O / O Flk O - O 1 O / O KDR O ) O was O also O examined O by O immunohistochemistry O . O The O results O demonstrated O that O 17beta B-Chemical - I-Chemical estradiol I-Chemical ( O E2 B-Chemical ) O induces O neovascularization O , O as O well O as O the O growth O and O enlargement O of O blood O vessels O after O 7 O days O of O exposure O . O The O high O tumor B-Disease angiogenic O potential O was O associated O with O an O elevated O VEGF O / O VPF O protein O expression O in O the O E2 B-Chemical exposed O pituitary O of O ovariectomized O ( O OVEX O ) O rats O . O VEGF O / O VPF O and O FVIIIRAg O immunohistochemistry O and O endothelial O specific O lectin O ( O UEA1 O ) O binding O studies O , O indicate O that O the O elevation O of O VEGF O protein O expression O initially O occurred O in O both O blood O vessels O and O non O - O endothelial O cells O . O After O 15 O days O of O E2 B-Chemical exposure O , O VEGF O / O VPF O protein O expression O , O in O the O non O - O endothelial O cell O population O , O sharply O declined O and O was O restricted O to O the O blood O vessels O . O The O function O of O non O - O endothelial O - O derived O VEGF O is O not O clear O . O Furthermore O , O immunohistochemical O studies O demonstrated O that O VEGFR O - O 2 O ( O flk O - O 1 O / O KDR O ) O , O expression O was O elevated O significantly O in O the O endothelial O cells O of O microblood O vessels O after O 7 O days O of O E2 B-Chemical exposure O . O These O findings O suggest O that O over O expression O of O VEGF O and O its O receptor O ( O VEGFR O - O 2 O ) O may O play O an O important O role O in O the O initial O step O of O the O regulation O of O estrogen B-Chemical induced O tumor B-Disease angiogenesis O in O the O rat O pituitary O . O Persistent O nephrogenic B-Disease diabetes I-Disease insipidus I-Disease following O lithium B-Chemical therapy O . O We O report O the O case O of O a O patient O who O developed O severe O hypernatraemic O dehydration B-Disease following O a O head B-Disease injury I-Disease . O Ten O years O previously O he O had O been O diagnosed O to O have O lithium B-Chemical - O induced O nephrogenic B-Disease diabetes I-Disease insipidus I-Disease , O and O lithium B-Chemical therapy O had O been O discontinued O . O He O remained O thirsty O and O polyuric B-Disease despite O cessation O of O lithium B-Chemical and O investigations O on O admission O showed O him O to O have O normal O osmoregulated O thirst O and O vasopressin B-Chemical secretion O , O with O clear O evidence O of O nephrogenic B-Disease diabetes I-Disease insipidus I-Disease . O Lithium B-Chemical induced O nephrogenic B-Disease diabetes I-Disease insipidus I-Disease is O considered O to O be O reversible O on O cessation O of O therapy O but O polyuria B-Disease persisted O in O this O patient O for O ten O years O after O lithium B-Chemical was O stopped O .

O Posteroventral O medial O pallidotomy O in O advanced O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease . O BACKGROUND O : O Posteroventral O medial O pallidotomy O sometimes O produces O striking O improvement O in O patients O with O advanced O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease , O but O the O studies O to O date O have O involved O small O numbers O of O patients O and O short O - O term O follow O - O up O . O METHODS O : O Forty O patients O with O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease underwent O serial O , O detailed O assessments O both O after O drug O withdrawal O ( O " O off O " O period O ) O and O while O taking O their O optimal O medical O regimens O ( O " O on O " O period O ) O . O All O patients O were O examined O preoperatively O and O 39 O were O examined O at O six O months O ; O 27 O of O the O patients O were O also O examined O at O one O year O , O and O 11 O at O two O years O . O RESULTS O : O The O percent O improvements O at O six O months O were O as O follows O : O off O - O period O score O for O overall O motor O function O , O 28 O percent O ( O 95 O percent O confidence O interval O , O 19 O to O 38 O percent O ) O , O with O most O of O the O improvement O in O the O contralateral O limbs O ; O off O - O period O score O for O activities O of O daily O living O , O 29 O percent O ( O 95 O percent O confidence O interval O , O 19 O to O 39 O percent O ) O ; O on O - O period O score O for O contralateral O dyskinesias B-Disease , O 82 O percent O ( O 95 O percent O confidence O interval O , O 72 O to O 91 O percent O ) O ; O and O on O - O period O score O for O ipsilateral O dyskinesias B-Disease , O 44 O percent O ( O 95 O percent O confidence O interval O , O 29 O to O 59 O percent O ) O . O The O improvements O in O dyskinesias B-Disease and O the O total O scores O for O off O - O period O parkinsonism B-Disease , O contralateral O bradykinesia B-Disease , O and O rigidity B-Disease were O sustained O in O the O 11 O patients O examined O at O two O years O . O The O improvement O in O ipsilateral O dyskinesias B-Disease was O lost O after O one O year O , O and O the O improvements O in O postural O stability O and O gait O lasted O only O three O to O six O months O . O Approximately O half O the O patients O who O had O been O dependent O on O assistance O in O activities O of O daily O living O in O the O off O period O before O surgery O became O independent O after O surgery O . O The O complications O of O surgery O were O generally O well O tolerated O , O and O there O were O no O significant O changes O in O the O use O of O medication O . O CONCLUSIONS O : O In O late O - O stage O Parkinson B-Disease ' I-Disease s I-Disease disease I-Disease , O pallidotomy O significantly O reduces O levodopa B-Chemical - O induced O dyskinesias B-Disease and O off O - O period O disability O . O Much O of O the O benefit O is O sustained O at O two O years O , O although O some O improvements O , O such O as O those O on O the O ipsilateral O side O and O in O axial O symptoms O , O wane O within O the O first O year O . O The O on O - O period O symptoms O that O are O resistant O to O dopaminergic O therapy O do O not O respond O to O pallidotomy O . O Clarithromycin B-Chemical - O induced O ventricular B-Disease tachycardia I-Disease . O Clarithromycin B-Chemical is O a O relatively O new O macrolide B-Chemical antibiotic O that O offers O twice O - O daily O dosing O . O It O differs O from O erythromycin B-Chemical only O in O the O methylation O of O the O hydroxyl O group O at O position O 6 O . O Although O the O side O - O effect O profile O of O erythromycin B-Chemical is O established O , O including O gastroenteritis B-Disease and O interactions O with O other O drugs O subject O to O hepatic O mixed O - O function O oxidase O metabolism O , O experience O with O the O newer O macrolides B-Chemical is O still O being O recorded O .

O Four O patients O with O rheumatoid B-Disease arthritis I-Disease developed O heavy O proteinuria B-Disease after O five O to O 12 O months O of O treatment O with O D B-Chemical - I-Chemical penicillamine I-Chemical . O Light O microscopy O of O renal O biopsy O samples O showed O minimal O glomerular O capillary O wall O thickening O and O mesangial O matrix O increase O , O or O no O departure O from O normal O . O Electron O microscopy O , O however O , O revealed O subepithelial O electron O - O dense O deposits O , O fusion O of O epithelial O cell O foot O processes O , O and O evidence O of O mesangial O cell O hyperactivity O .

O The O findings O were O similar O to O those O in O early O membranous B-Disease glomerulonephritis I-Disease , O differences O being O observed O however O in O the O results O of O staining O for O the O early O - O acting O complement O components O C1q O and O C4 O . O It O is O tentatively O concluded O that O complement O was O activated O by O the O classical O pathway O . O Experimental O cranial O pain B-Disease elicited O by O capsaicin B-Chemical : O a O PET O study O . O Using O a O positron O emission O tomography O ( O PET O ) O study O it O was O shown O recently O that O in O migraine B-Disease without O aura O certain O areas O in O the O brain O stem O were O activated O during O the O headache B-Disease state O , O but O not O in O the O headache B-Disease free O interval O . O It O was O suggested O that O this O brain O stem O activation O is O inherent O to O the O migraine B-Disease attack O itself O and O represents O the O so O called O ' O migraine B-Disease generator O ' O . O To O test O this O hypothesis O we O performed O an O experimental O pain B-Disease study O in O seven O healthy O volunteers O , O using O the O same O positioning O in O the O PET O scanner O as O in O the O migraine B-Disease patients O . O A O small O amount O of O capsaicin B-Chemical was O administered O subcutaneously O in O the O right O forehead O to O evoke O a O burning O painful B-Disease sensation O in O the O first O division O of O the O trigeminal O nerve O .

O Sixty O - O five O patients O , O 34 O women O and O 31 O men O , O ages O 36 O to O 80 O years O , O received O either O normal O saline O before O and O after O TDI O ( O group O 1 O ) O , O 125 O mg O i O .

O Patients O were O observed O for O 72 O hours O and O reactions O were O recorded O and O graded O according O to O severity O . O Fifty O - O eight O percent O of O group O 1 O patients O , O 33 O % O of O group O 2 O , O and O 26 O % O of O group O 3 O had O reactions O to O TDI O . O The O severity O of O reactions O ( O minimal O , O mild O , O and O moderate O , O respectively O ) O was O as O follows O : O group O 1 O - O - O 6 O , O 6 O , O and O 2 O ; O group O 2 O - O - O 1 O , O 5 O , O and O 0 O ; O group O 3 O - O - O 5 O , O 1 O , O and O 0 O . O Data O were O analyzed O by O the O two O - O sided O Fisher O ' O s O exact O test O using O 95 O % O confidence O intervals O with O the O approximation O of O Woolf O . O These O data O demonstrate O that O administration O of O MP B-Chemical before O and O after O TDI O reduces O the O frequency O and O severity O of O the O arthralgia B-Disease - O myalgia B-Disease syndrome O . O We O conclude O that O 125 O mg O i O . O v O . O MP B-Chemical should O be O given O routinely O before O and O after O TDI O of O iron B-Chemical dextran I-Chemical .

O The O patient O was O in O near O syncope B-Disease and O had O QT B-Disease - I-Disease interval I-Disease prolongation I-Disease . O After O discontinuing O cisapride B-Chemical , O the O QT O interval O returned O to O normal O and O symptoms O did O not O recur O . O We O suggest O that O caution O be O taken O when O cisapride B-Chemical is O prescribed O with O any O potent O inhibitor O of O CYP3A4 O , O including O diltiazem B-Chemical .

O Since O tamoxifen B-Chemical is O widely O used O in O breast B-Disease cancer I-Disease treatment O and O has O been O proposed O for O the O prevention O of O breast B-Disease cancer I-Disease , O its O endometrial O iatrogenic O effects O must O be O carefully O examined O . O We O have O investigated O the O association O between O endometrial B-Disease cancer I-Disease and O tamoxifen B-Chemical use O or O other O treatments O in O women O treated O for O breast B-Disease cancer I-Disease in O a O case O - O control O study O .

O Pelvic O radiotherapy O may O be O an O additional O iatrogenic O factor O for O women O with O breast B-Disease cancer I-Disease . O Endometrial B-Disease cancers I-Disease diagnosed O in O women O treated O with O tamoxifen B-Chemical have O poorer O prognosis O . O Women O who O receive O tamoxifen B-Chemical for O breast B-Disease cancer I-Disease should O be O offered O gynaecological O surveillance O during O and O after O treatment O . O A O long O - O term O evaluation O of O the O risk O - O benefit O ratio O of O tamoxifen B-Chemical as O a O preventive O treatment O for O breast B-Disease cancer I-Disease is O clearly O warranted O . O Contribution O of O the O glycine B-Chemical site O of O NMDA B-Chemical receptors O in O rostral O and O intermediate O - O caudal O parts O of O the O striatum O to O the O regulation O of O muscle O tone O in O rats O . O The O aim O of O the O present O study O was O to O assess O the O contribution O of O the O glycine B-Chemical site O of O NMDA B-Chemical receptors O in O the O striatum O to O the O regulation O of O muscle O tone O . O Muscle O tone O was O examined O using O a O combined O mechanoand O electromyographic O method O , O which O measured O simultaneously O the O muscle O resistance O ( O MMG O ) O of O the O rat O ' O s O hind O foot O to O passive O extension O and O flexion O in O the O ankle O joint O and O the O electromyographic O activity O ( O EMG O ) O of O the O antagonistic O muscles O of O that O joint O : O gastrocnemius O and O tibialis O anterior O .

O 5 O microl O into O the O intermediate O - O caudal O region O of O the O striatum O of O rats O not O pretreated O with O haloperidol B-Chemical had O no O effect O on O the O muscle O tone O . O The O present O results O suggest O that O blockade O of O the O glycine B-Chemical site O of O NMDA B-Chemical receptors O in O the O rostral O part O of O the O striatum O may O be O mainly O responsible O for O the O antiparkinsonian O action O of O this O drug O . O Carboplatin B-Chemical toxic O effects O on O the O peripheral O nervous O system O of O the O rat O . O BACKGROUND O : O The O most O striking O of O carboplatin B-Chemical ' O s O advantages O ( O CBDCA B-Chemical ) O over O cisplatin B-Chemical ( O CDDP B-Chemical ) O is O its O markedly O reduced O rate O of O neurotoxic B-Disease effects O . O However O , O the O use O of O CBDCA B-Chemical higher O - O intensity O schedules O and O the O association O with O other O neurotoxic B-Disease drugs O in O polychemotherapy O may O cause O some O concern O about O its O safety O with O respect O to O peripheral B-Disease nervous I-Disease system I-Disease damage I-Disease . O MATERIALS O AND O METHODS O : O Two O different O schedules O of O CBDCA B-Chemical administration O ( O 10 O mg O / O kg O and O 15 O mg O / O kg O i O . O p O . O twice O a O week O for O nine O times O ) O were O evaluated O in O Wistar O rats O . O Neurotoxicity B-Disease was O assessed O for O behavioral O ( O tail O - O flick O test O ) O , O neurophysiological O ( O nerve O conduction O velocity O in O the O tail O nerve O ) O , O morphological O , O morphometrical O and O analytical O effects O . O RESULTS O : O CBDCA B-Chemical administration O induced O dose O - O dependent O peripheral B-Disease neurotoxicity I-Disease . O Pain B-Disease perception O and O nerve O conduction O velocity O in O the O tail O were O significantly O impaired O , O particularly O after O the O high O - O dose O treatment O . O The O dorsal O root O ganglia O sensory O neurons O and O , O to O a O lesser O extent O , O satellite O cells O showed O the O same O changes O as O those O induced O by O CDDP B-Chemical , O mainly O affecting O the O nucleus O and O nucleolus O of O ganglionic O sensory O neurons O . O Moreover O , O significant O amounts O of O platinum B-Chemical were O detected O in O the O dorsal O root O ganglia O and O kidney O after O CBDCA B-Chemical treatment O . O CONCLUSIONS O : O CBDCA B-Chemical is O neurotoxic B-Disease in O our O model O , O and O the O type O of O pathological O changes O it O induces O are O so O closely O similar O to O those O caused O by O CDDP B-Chemical that O it O is O probable O that O neurotoxicity B-Disease is O induced O in O the O two O drugs O by O the O same O mechanism O . O This O model O can O be O used O alone O or O in O combination O with O other O drugs O to O explore O the O effect O of O CBDCA B-Chemical on O the O peripheral O nervous O system O . O Effects O of O cisapride B-Chemical on O symptoms O and O postcibal O small O - O bowel O motor O function O in O patients O with O irritable B-Disease bowel I-Disease syndrome I-Disease . O BACKGROUND O : O Irritable B-Disease bowel I-Disease syndrome I-Disease is O a O common O cause O of O abdominal B-Disease pain I-Disease and O discomfort O and O may O be O related O to O disordered B-Disease gastrointestinal I-Disease motility I-Disease .

O Prevention O of O breast B-Disease cancer I-Disease with O tamoxifen B-Chemical : O preliminary O findings O from O the O Italian O randomised O trial O among O hysterectomised O women O . O Italian O Tamoxifen B-Chemical Prevention O Study O . O BACKGROUND O : O Tamoxifen B-Chemical is O a O candidate O chemopreventive O agent O in O breast B-Disease cancer I-Disease , O although O the O drug O may O be O associated O with O the O development O of O endometrial B-Disease cancer I-Disease . O Therefore O we O did O a O trial O in O hysterectomised O women O of O tamoxifen B-Chemical as O a O chemopreventive O . O METHODS O : O In O October O , O 1992 O , O we O started O a O double O - O blind O placebo O - O controlled O , O randomised O trial O of O tamoxifen B-Chemical in O women O ( O mainly O in O Italy O ) O who O did O not O have O breast B-Disease cancer I-Disease and O who O had O had O a O hysterectomy O . O Women O were O randomised O to O receive O tamoxifen B-Chemical 20 O mg O per O day O or O placebo O , O both O orally O for O 5 O years O . O The O original O plan O was O to O follow O the O intervention O phase O by O 5 O years O ' O follow O - O up O . O In O June O , O 1997 O , O the O trialists O and O the O data O - O monitoring O committee O decided O to O end O recruitment O primarily O because O of O the O number O of O women O dropping O out O of O the O study O . O Recruitment O ended O on O July O 11 O , O 1997 O , O and O the O study O will O continue O as O planned O . O The O primary O endpoints O are O the O occurrence O of O and O deaths O from O breast B-Disease cancer I-Disease . O This O preliminary O interim O analysis O is O based O on O intention O - O to O - O treat O . O FINDINGS O : O 5408 O women O were O randomised O ; O participating O women O have O a O median O follow O - O up O of O 46 O months O for O major O endpoints O . O 41 O cases O of O breast B-Disease cancer I-Disease occurred O so O far O ; O there O have O been O no O deaths O from O breast B-Disease cancer I-Disease . O There O is O no O difference O in O breast B-Disease - I-Disease cancer I-Disease frequency O between O the O placebo O ( O 22 O cases O ) O and O tamoxifen B-Chemical ( O 19 O ) O arms O . O There O is O a O statistically O significant O reduction O of O breast B-Disease cancer I-Disease among O women O receiving O tamoxifen B-Chemical who O also O used O hormone O - O replacement O therapy O during O the O trial O : O among O 390 O women O on O such O therapy O and O allocated O to O placebo O , O we O found O eight O cases O of O breast B-Disease cancer I-Disease compared O with O one O case O among O 362 O women O allocated O to O tamoxifen B-Chemical . O Compared O with O the O placebo O group O , O there O was O a O significantly O increased O risk O of O vascular B-Disease events I-Disease and O hypertriglyceridaemia B-Disease among O women O on O tamoxifen B-Chemical . O INTERPRETATION O : O Although O this O preliminary O analysis O has O low O power O , O in O this O cohort O of O women O at O low O - O to O - O normal O risk O of O breast B-Disease cancer I-Disease , O the O postulated O protective O effects O of O tamoxifen B-Chemical are O not O yet O apparent O . O Women O using O hormone O - O replacement O therapy O appear O to O have O benefited O from O use O of O tamoxifen B-Chemical . O There O were O no O deaths O from O breast B-Disease cancer I-Disease recorded O in O women O in O the O study O . O It O is O essential O to O continue O follow O - O up O to O quantify O the O long O - O term O risks O and O benefits O of O tamoxifen B-Chemical therapy O . O Epileptogenic O activity O of O folic B-Chemical acid I-Chemical after O drug O induces O SLE B-Disease ( O folic B-Chemical acid I-Chemical and O epilepsy B-Disease ) O OBJECTIVE O : O To O study O the O effect O of O folic B-Chemical acid I-Chemical - O containing O multivitamin O supplementation O in O epileptic B-Disease women O before O and O during O pregnancy O in O order O to O determine O the O rate O of O structural O birth B-Disease defects I-Disease and O epilepsy B-Disease - O related O side O effects O . O STUDY O DESIGN O : O First O a O randomised O trial O , O later O periconception O care O including O in O total O 12225 O females O . O RESULTS O : O Of O 60 O epileptic B-Disease women O with O periconceptional O folic B-Chemical acid I-Chemical ( O 0 O . O 8 O mg O ) O - O containing O multivitamin O supplementation O , O no O one O developed O epilepsy B-Disease - O related O side O effects O during O the O periconception O period O . O One O epileptic B-Disease woman O delivered O a O newborn O with O cleft B-Disease lip I-Disease and I-Disease palate I-Disease . O Another O patient O exhibited O with O a O cluster O of O seizures B-Disease after O the O periconception O period O using O another O multivitamin O . O This O 22 O - O year O - O old O epileptic B-Disease woman O was O treated O continuously O by O carbamazepine B-Chemical and O a O folic B-Chemical acid I-Chemical ( O 1 O mg O ) O - O containing O multivitamin O from O the O 20th O week O of O gestation O . O She O developed O status B-Disease epilepticus I-Disease and O later O symptoms O of O systemic B-Disease lupus I-Disease erythematodes I-Disease . O Her O pregnancy O ended O with O stillbirth B-Disease . O CONCLUSIONS O : O The O epileptic B-Disease pregnant O patient O ' O s O autoimmune B-Disease disease I-Disease ( O probably O drug O - O induced O lupus B-Disease ) O could O damage O the O blood O - O brain O barrier O , O therefore O the O therapeutic O dose O ( O > O or O = O 1 O mg O ) O of O folic B-Chemical acid I-Chemical triggered O a O cluster O of O seizures B-Disease . O Physiological O dose O ( O < O 1 O mg O ) O of O folic B-Chemical acid I-Chemical both O in O healthy O and O 60 O epileptic B-Disease women O , O all O without O any O autoimmune B-Disease disease I-Disease , O did O not O increase O the O risk O for O epileptic B-Disease seizures I-Disease . O Stroke B-Disease and O cocaine B-Chemical or O amphetamine B-Chemical use O . O The O association O of O cocaine B-Chemical and O amphetamine B-Chemical use O with O hemorrhagic O and O ischemic B-Disease stroke B-Disease is O based O almost O solely O on O data O from O case O series O . O The O limited O number O of O epidemiologic O studies O of O stroke B-Disease and O use O of O cocaine B-Chemical and O / O or O amphetamine B-Chemical have O been O done O in O settings O that O serve O mostly O the O poor O and O / O or O minorities O . O This O case O - O control O study O was O conducted O in O the O defined O population O comprising O members O of O Kaiser O Permanente O of O Northern O and O Southern O California O . O We O attempted O to O identify O all O incident O strokes B-Disease in O women O ages O 15 O - O 44 O years O during O a O 3 O - O year O period O using O hospital O admission O and O discharge O records O , O emergency O department O logs O , O and O payment O requests O for O out O - O of O - O plan O hospitalizations O . O We O selected O controls O , O matched O on O age O and O facility O of O usual O care O , O at O random O from O healthy O members O of O the O health O plan O . O We O obtained O information O in O face O - O to O - O face O interviews O . O There O were O 347 O confirmed O stroke B-Disease cases O and O 1 O , O 021 O controls O . O The O univariate O matched O odds O ratio O for O stroke B-Disease in O women O who O admitted O to O using O cocaine B-Chemical and O / O or O amphetamine B-Chemical was O 8 O . O 5 O ( O 95 O % O confidence O interval O = O 3 O . O 6 O - O 20 O . O 0 O ) O . O After O further O adjustment O for O potential O confounders O , O the O odds O ratio O in O women O who O reported O using O cocaine B-Chemical and O / O or O amphetamine B-Chemical was O 7 O . O 0 O ( O 95 O % O confidence O interval O = O 2 O . O 8 O - O 17 O . O 9 O ) O . O The O use O of O cocaine B-Chemical and O / O or O amphetamine B-Chemical is O a O strong O risk O factor O for O stroke B-Disease in O this O socioeconomically O heterogeneous O , O insured O urban O population O . O Acute B-Disease renal I-Disease failure I-Disease subsequent O to O the O administration O of O rifampicin B-Chemical . O A O follow O - O up O study O of O cases O reported O earlier O . O A O clinical O presentation O is O made O of O a O 2 O - O 3 O year O follow O - O up O of O six O cases O of O acute B-Disease renal I-Disease failure I-Disease that O have O been O reported O earlier O . O The O patients O had O developed O transient O renal B-Disease failure I-Disease after O the O intermittent O administration O of O rifampicin B-Chemical . O The O stage O of O olig O - O anuria B-Disease lasted O for O 1 O - O 3 O weeks O , O and O five O of O the O patients O were O treated O by O hemodialysis O . O Two O of O the O patients O died O due O to O unrelated O causes O during O the O follow O - O up O period O . O The O four O patients O re O - O examined O were O clinically O cured O . O Pathologic O findings O by O light O microscopy O and O immunofluorescence O at O biopsy O were O scarce O . O Nothing O abnormal O was O seen O by O electron O microscopy O in O two O of O the O cases O studied O . O Renal O function O was O normal O . O In O three O cases O the O excretion O at O 131I O - O hippuran O renography O was O slightly O slowed O . O Although O in O the O acute O stage O the O renal B-Disease lesions I-Disease histologically O appeared O toxic O , O evidence O suggestive O of O an O immunological O mechanism O cannot O be O excluded O . O Chronic O effects O of O a O novel O synthetic O anthracycline B-Chemical derivative O ( O SM B-Chemical - I-Chemical 5887 I-Chemical ) O on O normal O heart O and O doxorubicin B-Chemical - O induced O cardiomyopathy B-Disease in O beagle O dogs O . O This O study O was O designed O to O investigate O the O chronic O cardiotoxic B-Disease potential O of O SM B-Chemical - I-Chemical 5887 I-Chemical and O a O possible O deteriorating O effect O of O SM B-Chemical - I-Chemical 5887 I-Chemical on O low O - O grade O cardiotoxicity B-Disease pre O - O induced O by O doxorubicin B-Chemical in O beagle O dogs O . O In O the O chronic O treatment O , O beagle O dogs O of O each O sex O were O given O intravenously O once O every O 3 O weeks O , O either O a O sublethal O dose O of O doxorubicin B-Chemical ( O 1 O . O 5 O mg O / O kg O ) O or O SM B-Chemical - I-Chemical 5887 I-Chemical ( O 2 O . O 5 O mg O / O kg O ) O . O The O experiment O was O terminated O 3 O weeks O after O the O ninth O dosing O . O Animals O which O received O over O six O courses O of O doxorubicin B-Chemical demonstrated O the O electrocardiogram O ( O ECG O ) O changes O , O decrease O of O blood O pressure O and O high O - O grade O histopathological O cardiomyopathy B-Disease , O while O animals O which O were O terminally O sacrificed O after O the O SM B-Chemical - I-Chemical 5887 I-Chemical administration O did O not O show O any O changes O in O ECG O , O blood O pressure O and O histopathological O examinations O . O To O examine O a O possibly O deteriorating O cardiotoxic B-Disease effect O of O SM B-Chemical - I-Chemical 5887 I-Chemical , O low O - O grade O cardiomyopathy B-Disease was O induced O in O dogs O by O four O courses O of O doxorubicin B-Chemical ( O 1 O . O 5 O mg O / O kg O ) O . O Nine O weeks O after O pre O - O treatment O , O dogs O were O given O four O courses O of O either O doxorubicin B-Chemical ( O 1 O . O 5 O mg O / O kg O ) O or O SM B-Chemical - I-Chemical 5887 I-Chemical ( O 2 O . O 5 O mg O / O kg O ) O once O every O 3 O weeks O . O The O low O - O grade O cardiotoxic B-Disease changes O were O enhanced O by O the O additional O doxorubicin B-Chemical treatment O . O On O the O contrary O , O the O SM B-Chemical - I-Chemical 5887 I-Chemical treatment O did O not O progress O the O grade O of O cardiomyopathy B-Disease . O In O conclusion O , O SM B-Chemical - I-Chemical 5887 I-Chemical does O not O have O any O potential O of O chronic O cardiotoxicity B-Disease and O deteriorating O effect O on O doxorubicin B-Chemical - O induced O cardiotoxicity B-Disease in O dogs O . O Risk O for O valvular B-Disease heart I-Disease disease I-Disease among O users O of O fenfluramine B-Chemical and O dexfenfluramine B-Chemical who O underwent O echocardiography O before O use O of O medication O . O BACKGROUND O : O Because O uncontrolled O echocardiographic O surveys O suggested O that O up O to O 30 O % O to O 38 O % O of O users O of O fenfluramine B-Chemical and O dexfenfluramine B-Chemical had O valvular B-Disease disease I-Disease , O these O drugs O were O withdrawn O from O the O market O . O OBJECTIVE O : O To O determine O the O risk O for O new O or O worsening O valvular B-Disease abnormalities I-Disease among O users O of O fenfluramine B-Chemical or O dexfenfluramine B-Chemical who O underwent O echocardiography O before O they O began O to O take O these O medications O . O DESIGN O : O Cohort O study O . O SETTING O : O Academic O primary O care O practices O . O PATIENTS O : O 46 O patients O who O used O fenfluramine B-Chemical or O dexfenfluramine B-Chemical for O 14 O days O or O more O and O had O echocardiograms O obtained O before O therapy O .

O MATERIALS O AND O METHODS O : O Patients O undergoing O treatment O with O i O . O v O . O tobramycin B-Chemical ( O 4 O mg O / O kg O / O day O ) O were O randomised O to O two O groups O .

O CONCLUSION O : O This O small O study O suggests O that O a O once O - O daily O dosing O regimen O of O tobramycin B-Chemical is O at O least O as O effective O as O and O is O no O more O and O possibly O less O toxic O than O the O twice O - O daily O regimen O .

O Enhanced O bradycardia B-Disease induced O by O beta O - O adrenoceptor O antagonists O in O rats O pretreated O with O isoniazid B-Chemical . O High O doses O of O isoniazid B-Chemical increase O hypotension B-Disease induced O by O vasodilators O and O change O the O accompanying O reflex O tachycardia B-Disease to O bradycardia B-Disease , O an O interaction O attributed O to O decreased O synthesis O of O brain O gamma B-Chemical - I-Chemical aminobutyric I-Chemical acid I-Chemical ( O GABA B-Chemical ) O . O In O the O present O study O , O the O possible O enhancement O by O isoniazid B-Chemical of O bradycardia B-Disease induced O by O beta O - O adrenoceptor O antagonists O was O determined O in O rats O anaesthetised O with O chloralose B-Chemical - O urethane B-Chemical . O Isoniazid B-Chemical significantly O increased O bradycardia B-Disease after O propranolol B-Chemical , O pindolol B-Chemical , O labetalol B-Chemical and O atenolol B-Chemical , O as O well O as O after O clonidine B-Chemical , O but O not O after O hexamethonium B-Chemical or O carbachol B-Chemical . O Enhancement O was O not O observed O in O rats O pretreated O with O methylatropine B-Chemical or O previously O vagotomised O . O These O results O are O compatible O with O interference O by O isoniazid B-Chemical with O GABAergic O inhibition O of O cardiac O parasympathetic O tone O . O Such O interference O could O be O exerted O centrally O , O possibly O at O the O nucleus O ambiguus O , O or O peripherally O at O the O sinus O node O . O Structural B-Disease and I-Disease functional I-Disease impairment I-Disease of I-Disease mitochondria I-Disease in O adriamycin B-Chemical - O induced O cardiomyopathy B-Disease in O mice O : O suppression O of O cytochrome O c O oxidase O II O gene O expression O . O The O use O of O adriamycin B-Chemical ( O ADR B-Chemical ) O in O cancer B-Disease chemotherapy O has O been O limited O due O to O its O cumulative O cardiovascular B-Disease toxicity I-Disease . O Earlier O observations O that O ADR B-Chemical interacts O with O mitochondrial O cytochrome O c O oxidase O ( O COX O ) O and O suppresses O its O enzyme O activity O led O us O to O investigate O ADR B-Chemical ' O s O action O on O the O cardiovascular O functions O and O heart O mitochondrial O morphology O in O Balb O - O c O mice O i O . O p O . O treated O with O ADR B-Chemical for O several O weeks O . O At O various O times O during O treatment O , O the O animals O were O assessed O for O cardiovascular O functions O by O electrocardiography O and O for O heart O tissue O damage O by O electron O microscopy O . O In O parallel O , O total O RNA O was O extracted O from O samples O of O dissected O heart O and O analyzed O by O Northern O blot O hybridization O to O determine O the O steady O - O state O level O of O three O RNA O transcripts O encoded O by O the O COXII O , O COXIII O , O and O COXIV O genes O . O Similarly O , O samples O obtained O from O the O liver O of O the O same O animals O were O analyzed O for O comparative O studies O . O Our O results O indicated O that O 1 O ) O treatment O of O mice O with O ADR B-Chemical caused O cardiovascular B-Disease arrhythmias I-Disease characterized O by O bradycardia B-Disease , O extension O of O ventricular O depolarization O time O ( O tQRS O ) O , O and O failure O of O QRS O at O high O concentrations O ( O 10 O - O 14 O mg O / O kg O body O weight O cumulative O dose O ) O ; O 2 O ) O the O heart O mitochondria O underwent O swelling B-Disease , O fusion O , O dissolution O , O and O / O or O disruption O of O mitochondrial O cristae O after O several O weeks O of O treatment O . O Such O abnormalities O were O not O observed O in O the O mitochondria O of O liver O tissue O ; O and O 3 O ) O among O the O three O genes O of O COX O enzyme O examined O , O only O COXII O gene O expression O was O suppressed O by O ADR B-Chemical treatment O , O mainly O after O 8 O weeks O in O both O heart O and O liver O . O Knowing O that O heart O mitochondria O represent O almost O 40 O % O of O heart O muscle O by O weight O , O we O conclude O that O the O deteriorating O effects O of O ADR B-Chemical on O cardiovascular O function O involve O mitochondrial B-Disease structural I-Disease and I-Disease functional I-Disease impairment I-Disease . O Gene O expression O studies O in O isolated O mitochondria O : O Solanum B tuberosum I rps10 O is O recognized O by O cognate O potato B but O not O by O the O transcription O , O splicing O and O editing O machinery O of O wheat B mitochondria O Abstract O The O complex O gene O expression O mechanisms O that O occur O in O plant O mitochondria O , O such O as O RNA O editing O and O splicing O , O are O not O yet O well O understood O . O RNA O editing O in O higher O plant O mitochondria O is O a O highly O specific O process O which O modifies O mRNA O sequences O by O C O - O to O - O U O conversions O . O It O has O been O suggested O that O in O some O cases O this O process O is O required O for O splicing O . O Here O , O we O use O an O experimental O model O based O on O the O introduction O of O DNA O into O isolated O mitochondria O by O electroporation O to O study O organellar O gene O expression O events O . O Our O aim O was O to O compare O processing O and O editing O of O potato B small O ribosomal O protein O 10 O gene O ( O rps10 O ) O transcripts O in O heterologous O ( O wheat B mitochondria O ) O and O homologous O ( O potato B mitochondria O ) O contexts O . O rps10 O is O a O suitable O model O because O it O contains O a O group O II O intron O , O is O absent O in O wheat B mitochondria O but O is O actively O expressed O in O potato B mitochondria O , O where O transcripts O are O spliced O and O undergo O five O C O - O to O - O U O editing O events O . O For O this O purpose O , O conditions O for O electroporating O isolated O potato B mitochondria O were O established O . O rps10 O was O placed O under O the O control O of O either O potato B or O wheat B cox2 O promoters O . O We O found O that O rps10 O was O only O transcribed O under O the O control O of O a O cognate O promoter O . O In O wheat B mitochondria O , O rps10 O transcripts O were O neither O spliced O nor O edited O while O they O are O correctly O processed O in O potato B mitochondria O . O Interestingly O , O a O wheat B editing O site O grafted O into O rps10 O was O not O recognized O by O wheat B mitochondria O but O was O correctly O edited O in O potato B mitochondria O . O Taken O together O , O these O results O suggest O that O editing O might O occur O only O when O the O transcripts O are O engaged O in O processing O and O that O they O would O not O be O available O to O editing O factors O outside O of O a O putative O RNA O maturation O machinery O complex O . O INTRODUCTION O Gene O expression O in O plant O mitochondria O is O a O complex O process O involving O multiple O steps O such O as O transcription O , O cis O - O and O trans O - O splicing O , O RNA O trimming O and O RNA O editing O on O the O way O to O translation O ( O 1 O ) O . O RNA O editing O has O been O found O in O a O variety O of O organisms O and O occurs O through O different O mechanisms O such O as O insertion O or O deletion O of O nucleotides O , O or O base O conversions O [ O for O details O see O reference O ( O 2 O ) O ] O . O In O higher O plant O organelles O , O RNA O editing O is O an O important O post O - O transcriptional O event O characterized O by O C O - O to O - O U O changes O via O a O deamination O mechanism O ( O 3 O - O 5 O ) O . O In O Arabidopsis B thaliana I 456 O C O - O to O - O U O editing O events O have O been O described O ( O 6 O ) O . O RNA O editing O occurs O mostly O in O the O coding O regions O which O alter O the O identity O of O the O encoded O amino O acid O , O but O some O editing O events O occur O in O highly O structured O regions O of O introns O ( O 7 O , O 8 O ) O . O Like O other O maturation O processes O , O RNA O editing O is O an O essential O post O - O transcriptional O event O in O plant O mitochondrial O gene O expression O ( O 9 O - O 11 O ) O required O for O the O synthesis O of O functional O proteins O ( O 12 O , O 13 O ) O . O The O introduction O of O foreign O DNA O into O isolated O mitochondria O is O a O novel O experimental O model O which O has O provided O important O information O on O RNA O editing O and O RNA O splicing O enabling O the O use O of O a O site O - O directed O mutagenesis O approach O ( O 14 O , O 15 O ) O . O Using O a O cognate O cox2 O chimeric O gene O construct O , O the O cis O - O recognition O elements O required O for O plant O mitochondria O RNA O editing O have O been O determined O ( O 16 O , O 17 O ) O . O Using O the O same O approach O , O Staudinger O and O Kempken O ( O 18 O ) O have O reported O that O transcripts O from O A B . I thaliana I cox2 O , O but O not O Sorghum B bicolor I atp6 O , O are O edited O when O the O genes O are O introduced O into O maize B mitochondria O . O Interestingly O , O higher O plant O mitochondrial O genomes O differ O in O their O gene O contents O due O to O an O evolutionary O information O transfer O from O the O organelle O to O the O nucleus O ( O 19 O ) O . O Of O particular O interest O is O the O situation O of O the O small O ribosomal O protein O 10 O gene O ( O rps10 O ) O , O a O group O II O intron O - O bearing O gene O which O is O encoded O in O Solanum B tuberosum I mitochondrial O DNA O but O is O absent O from O the O wheat B mitochondrial O genome O ( O 20 O ) O . O Higher O plant O mitochondria O contain O group O II O introns O either O in O cis O - O or O trans O - O configuration O ( O 1 O ) O which O can O be O folded O in O a O characteristic O secondary O structure O ( O 21 O ) O . O Intron O removal O in O plant O mitochondrial O mRNAs O is O not O well O documented O because O such O introns O are O unable O to O self O - O splice O . O Previously O , O we O described O that O electroporated O cox2 O constructs O were O a O good O model O for O the O study O of O the O splicing O process O . O Using O this O model O , O we O found O that O editing O and O splicing O of O cox2 O transcripts O were O not O linked O in O wheat B mitochondria O ( O 15 O ) O . O To O challenge O the O ability O of O mitochondrial O gene O expression O machinery O to O recognize O genetic O information O which O has O been O lost O during O evolution O , O we O decided O to O introduce O the O S B . I tuberosum I non O - O cognate O rps10 O gene O into O wheat B mitochondria O . O Five O C O residues O are O changed O to O U O in O potato B mitochondria O rps10 O transcripts O by O editing O . O Two O of O them O have O been O postulated O as O being O necessary O for O acquisition O of O a O proper O secondary O and O / O or O tertiary O structure O for O splicing O . O To O test O this O hypothesis O , O it O was O necessary O to O set O up O the O conditions O for O electroporation O of O foreign O DNA O into O S B . I tuberosum I mitochondria O . O Here O , O we O show O that O a O potato B rps10 O construct O is O transcribed O when O introduced O into O wheat B mitochondria O , O but O transcripts O are O not O recognized O by O the O post O - O transcriptional O processing O machinery O . O In O contrast O , O a O rps10 O construct O is O correctly O expressed O and O processed O in O cognate O potato B mitochondria O . O Moreover O , O we O present O evidence O that O transcript O editing O might O be O linked O to O overall O RNA O processing O . O This O is O the O first O report O on O DNA O electroporation O into O potato B mitochondria O .

I tuberosum I cox2 O gene O , O a O KpnI O / O SpeI O fragment O containing O the O 727 O bp O upstream O region O and O the O complete O coding O region O was O used O to O replace O the O wheat B gene O from O pCOXII O . O As O for O pCOXII O , O a O NsiI O site O was O inserted O at O the O ATG O start O codon O and O a O 23 O bp O fragment O was O inserted O at O position O - O 20 O .

I aestivum I or O S B . I tuberosum I promoters O .

O In O potato B , O the O mature O product O is O barely O detectable O . O In O contrast O to O wheat B mitochondria O , O the O 821 O nt O mature O transcript O was O only O detected O when O the O electroporated O potato B mitochondria O were O incubated O in O the O presence O of O fatty O acid O - O free O BSA O . O A O cognate O rps10 O construct O is O correctly O expressed O , O edited O and O processed O in O potato B mitochondria O The O construct O expressing O potato B rps10 O under O the O control O of O potato B cox2 O promoter O was O introduced O into O S B . I tuberosum I isolated O mitochondria O . O After O incubation O , O the O precursor O and O mature O transcripts O were O amplified O by O RT O - O PCR O ( O Figure O 5A O ) O and O sequenced O .

O A O cognate O editing O site O in O a O non O - O native O context O is O not O recognized O by O wheat B mitochondria O but O is O recognized O in O heterologous O mitochondria O To O test O whether O wheat B mitochondria O are O able O to O edit O a O cognate O site O when O placed O in O the O context O of O a O potato B transcript O , O we O introduced O the O C259 O - O 16 O / O + O 6 O region O from O wheat B cox2 O into O potato B rps10 O exon O 1 O or O intron O ( O Figure O 6A O , O construct O MA O and O ME6 O , O respectively O ) O . O As O reported O previously O , O the O 23 O nt O region O forming O the O C259 O editing O site O from O wheat B cox2 O was O efficiently O edited O when O grafted O into O a O different O context O in O a O wheat B transcript O ( O 17 O ) O . O Wild O - O type O rps10 O ( O pRPS10W O ) O and O the O MA O and O ME6 O mutants O were O expressed O in O wheat B mitochondria O but O no O splicing O was O observed O ( O Figure O 6B O ) O . O Unexpectedly O , O wheat B mitochondria O appear O to O be O unable O to O edit O the O cognate O C259 O site O when O the O - O 16 O / O + O 6 O region O is O located O on O a O potato B rps10 O precursor O . O The O control O CM O construct O , O containing O the O C259 O site O grafted O in O a O different O context O but O in O its O own O cox2 O gene O , O was O expressed O , O spliced O and O edited O as O expected O [ O ( O 17 O ) O , O Figure O 6B O and O D O ] O . O To O compare O the O editing O status O of O RNAs O at O the O same O stage O of O processing O , O the O editing O status O of O the O inserted O C259 O site O in O precursor O cox2 O transcripts O is O shown O ( O Figure O 6D O ) O . O The O analogous O MAb O and O ME6b O constructs O , O containing O the O S B . I tuberosum I cox2 O promoter O and O the O C259 O region O inserted O into O rps10 O exon O 1 O and O intron O were O used O to O electroporate O potato B mitochondria O . O As O shown O in O Figure O 6C O , O MAb O and O ME6b O were O expressed O and O spliced O at O the O same O level O as O the O control O in O the O homologous O context O , O indicating O that O insertion O does O not O affect O the O splicing O process O . O Interestingly O , O while O C259 O insertion O was O not O recognized O in O wheat B mitochondria O ( O Figure O 6D O ) O , O the O potato B RNA O editing O machinery O edited O the O inserted O C259 O region O ( O Figure O 6E O ) O . O The O C259 O region O inserted O in O the O rps10 O intron O ( O construct O ME6b O ) O was O also O edited O , O although O at O a O very O low O level O , O showing O that O editing O may O precede O intron O removal O ( O not O shown O ) O . O DISCUSSION O Plant O mitochondria O undergo O complex O expression O mechanisms O which O are O poorly O understood O . O Most O studies O are O based O on O analysis O of O in O vivo O mature O or O intermediate O gene O products O giving O clues O on O possible O mechanisms O and O suggesting O pathways O operating O in O gene O expression O . O Direct O tests O using O in O vitro O approaches O have O been O fruitful O ( O 4 O , O 5 O , O 24 O ) O , O but O are O hampered O by O the O difficulty O of O obtaining O active O mitochondrial O extracts O . O Previously O , O we O devised O an O experimental O model O based O on O electroporation O of O isolated O mitochondria O that O allows O us O to O test O gene O expression O of O wild O - O type O and O mutant O genes O . O This O approach O has O been O very O useful O in O elucidating O the O process O of O RNA O maturation O in O plant O mitochondria O , O in O particular O splicing O and O editing O ( O 14 O , O 15 O ) O . O The O aim O of O this O work O was O to O analyse O different O gene O expression O events O when O a O foreign O gene O was O expressed O in O a O heterologous O context O . O rps10 O was O chosen O precisely O because O this O genetic O information O is O lacking O in O wheat B mitochondria O but O is O active O in O potato B mitochondria O ( O 20 O , O 23 O , O 25 O ) O . O Moreover O , O rps10 O transcripts O undergo O five O C O - O to O - O U O editing O events O in O potato B mitochondria O and O rps10 O contains O an O intron O , O thus O facilitating O the O analysis O of O post O - O transcriptional O processing O . O To O best O evaluate O the O expression O of O rps10 O in O the O non O - O cognate O mitochondria O , O it O was O necessary O to O set O up O electroporation O conditions O for O introducing O foreign O DNA O into O S B . I tuberosum I mitochondria O . O Potato B tuber O mitochondria O were O able O to O incorporate O DNA O essentially O under O the O same O conditions O described O for O wheat B embryo O organelles O ( O 14 O ) O , O except O that O the O optimal O voltage O range O was O larger O . O A O major O difference O to O wheat B was O that O isolated O potato B mitochondria O were O viable O for O 3 O - O 4 O h O as O measured O by O oxygen O consumption O ( O data O not O shown O ) O . O Thus O , O to O observe O transcript O maturation O after O electroporation O the O incubation O mixture O needed O to O be O supplemented O with O fatty O acid O - O free O BSA O ( O see O Figure O 4 O ) O . O This O behaviour O probably O reflects O the O uncoupling O of O oxidative O phosphorylation O by O fatty O acids O during O incubation O of O potato B mitochondria O ( O 26 O ) O . O In O fact O , O previously O we O found O that O proper O gene O expression O in O isolated O mitochondria O requires O a O functional O organelle O able O to O generate O ATP O from O ADP O and O succinate O ( O 14 O ) O . O An O interesting O observation O was O that O neither O the O wheat B nor O the O potato B cox2 O promoters O were O recognized O in O a O heterologous O context O ( O Figure O 4A O and O B O ) O . O This O situation O might O by O explained O by O the O fact O that O potato B and O wheat B promoter O sequences O have O no O recognizable O homologous O motifs O . O Plant O mitochondria O promoters O are O characterized O by O a O conserved O core O CRTA O sequence O with O differences O in O the O extent O and O the O composition O of O sequences O around O the O consensus O motif O ( O 27 O , O 28 O ) O . O While O the O transcription O initiation O site O in O wheat B mitochondria O is O located O at O position O - O 170 O ( O 29 O ) O , O the O potato B promoter O has O not O yet O been O described O . O Transcription O may O be O initiated O at O numerous O sites O suggesting O a O relaxed O promoter O recognition O by O the O transcription O machinery O ( O 28 O ) O . O However O , O the O lack O of O crossed O recognition O of O cox2 O promoters O in O wheat B and O potato B is O not O a O general O situation O since O the O A B . I thaliana I cox2 O gene O is O expressed O and O spliced O when O introduced O into O maize B mitochondria O , O indicating O that O the O Arabidopsis B gene O shares O some O signals O with O maize B cox2 O promoter O that O are O sufficient O for O transcription O ( O 18 O ) O . O The O sites O required O for O transcript O initiation O have O been O recently O described O in O A B . I thaliana I mitochondrial O genes O ( O 28 O ) O . O Three O regions O were O described O as O important O for O transcription O initiation O . O We O found O no O such O homologous O sequences O in O the O potato B cox2 O upstream O region O indicating O that O the O two O dicot O promoters O do O not O have O the O same O origin O . O This O in O turn O may O reflect O the O natural O history O of O this O particular O mitochondrial O gene O evolving O in O its O own O context O . O It O should O be O mentioned O that O the O presence O of O a O conserved O sequence O is O not O sufficient O for O expression O since O a O region O that O acts O as O promoter O in O Arabidopsis B , O potato B and O Oenothera O is O inactive O in O vivo O in O pea B ( O 30 O ) O . O Further O studies O will O be O required O to O understand O the O transcriptional O events O in O plant O mitochondria O . O Electroporation O of O foreign O DNA O into O isolated O mitochondria O provides O an O interesting O functional O model O , O complementary O to O in O vitro O transcription O assay O , O for O answering O these O questions O . O The O potato B rps10 O gene O controlled O by O a O T B . I aestivum I promoter O ( O Figure O 1A O ) O was O transcribed O as O a O 1204 O nt O precursor O in O wheat B mitochondria O , O but O no O traces O of O mature O RNA O were O observed O . O Moreover O , O the O five O C O residues O reported O as O RNA O editing O targets O in O vivo O ( O 23 O ) O remain O unchanged O , O indicating O that O rps10 O transcript O was O not O recognized O by O the O wheat B splicing O and O editing O machinery O . O A O control O using O the O cognate O cox2 O construct O demonstrates O that O electroporated O organelles O were O competent O for O splicing O and O editing O ( O Figure O 1B O and O C O ) O . O Some O editing O events O occur O in O highly O structured O domains O of O introns O . O Because O in O some O cases O , O editing O corrects O A O - O C O mispairing O improving O conformation O of O the O intron O , O it O has O been O proposed O that O the O C O - O to O - O U O change O might O be O necessary O for O efficient O splicing O ( O 8 O , O 9 O , O 23 O , O 31 O ) O . O Based O on O the O canonical O structure O of O group O II O mitochondrial O introns O ( O 21 O ) O , O two O editing O sites O , O C2 O located O at O the O Intron O Binding O Site O 2 O ( O IBS2 O ) O and O C3 O located O in O the O intron O , O nine O residues O downstream O from O the O end O of O exon O 1 O in O S B . I tuberosum I rps10 O are O of O particular O interest O . O It O has O been O predicted O that O both O edited O residues O participate O in O base O - O pair O interactions O in O the O putative O secondary O structure O . O Of O particular O interest O is O the O site O C3 O located O in O intron O domain O I O ( O 23 O ) O . O This O position O may O be O crucial O for O splicing O as O inferred O from O mutants O of O a O yeast B mitochondrial O intron O ( O 32 O ) O . O We O addressed O this O question O by O introducing O rps10 O mutant O genes O presenting O C2 O , O C3 O or O both O positions O in O the O edited O form O into O mitochondria O . O As O shown O in O Figure O 2 O , O transcription O was O as O efficient O as O for O the O cognate O cox2 O construct O but O neither O wild O - O type O rps10 O nor O the O C O - O U O mutants O underwent O splicing O . O These O results O clearly O demonstrate O that O C2 O and O C3 O editing O is O not O sufficient O for O splicing O of O rps10 O precursor O in O wheat B mitochondria O and O lead O us O to O conclude O that O splicing O failure O is O probably O linked O to O the O lack O of O trans O - O recognition O elements O . O One O may O speculate O that O these O trans O - O acting O factors O , O for O instance O nuclear O - O encoded O maturases O , O were O lost O after O rps10 O was O transferred O to O the O nucleus O in O monocots O ( O 20 O , O 25 O ) O . O The O C O - O to O - O U O mutants O were O also O tested O in O potato B mitochondria O ; O no O significant O differences O were O detected O in O splicing O efficiency O when O compared O to O the O unedited O construct O ( O D O . O Choury O , O unpublished O data O ) O . O It O should O be O noted O that O the O lack O of O splicing O in O wheat B mitochondria O is O not O a O general O feature O of O potato B introns O , O since O the O potato B cox2 O intron O is O removed O efficiently O ( O Figure O 4B O ) O . O This O is O consistent O with O the O hypothesis O that O potato B and O wheat B mitochondria O have O similar O trans O - O acting O factors O for O cox2 O intron O removal O . O A O possible O link O between O intron O removal O and O editing O has O been O proposed O for O splicing O of O nad1e O and O nad5III O trans O - O introns O where O domain O six O may O require O editing O to O be O structured O in O a O catalytic O competent O secondary O conformation O ( O 8 O ) O . O In O rice B , O failure O of O RNA O maturation O and O editing O has O been O correlated O with O cytoplasmic O male O sterile O phenotype O . O In O this O model O , O the O absence O of O the O nuclear O gene O Rf O - O 1 O affects O B O - O atp6 O RNA O cleavage O and O editing O ( O 33 O ) O . O In O organello O studies O have O shown O that O S B . I bicolor I atp6 O - O 1 O gene O was O transcribed O but O not O edited O when O introduced O into O maize B mitochondria O ( O 18 O ) O . O However O , O partially O edited O molecules O were O detected O in O sorghum B - O maize B atp6 O chimeric O transcripts O when O they O included O the O maize B atp6 O 5 O ' O - O untranslated O sequence O , O suggesting O that O the O 5 O ' O non O - O coding O region O provides O a O structural O motif O or O binding O site O for O a O transcript O - O specific O editing O factor O ( O 34 O ) O . O Unfortunately O , O no O data O on O atp6 O processing O was O reported O to O determine O whether O this O region O is O directly O involved O in O editing O or O some O other O maturation O event O . O Since O wheat B mitochondria O do O not O have O rps10 O encoded O in O the O mitochondrial O genome O ( O 20 O ) O , O it O was O interesting O to O test O whether O wheat B mitochondria O were O able O to O recognize O editing O sites O which O had O been O lost O during O evolution O . O In O other O words O , O whether O the O mitochondrial O trans O - O recognition O elements O are O specific O for O each O site O or O whether O they O are O operating O on O a O subset O of O editing O sites O . O This O question O is O important O since O to O date O the O factors O responsible O for O RNA O editing O in O plant O mitochondria O remain O unknown O . O Solving O this O issue O may O provide O clues O to O uncover O such O factors O . O As O described O above O , O the O rps10 O transcript O was O not O processed O in O wheat B but O it O was O correctly O spliced O in O cognate O mitochondria O ( O Figure O 5A O ) O . O Indeed O , O the O mature O transcript O had O identical O exon1 O and O exon2 O junction O as O found O in O endogenous O rps10 O mRNA O ( O data O not O shown O ) O . O More O importantly O , O all O editing O sites O , O C1 O , O C2 O , O C4 O and O C5 O were O significantly O converted O to O Us O ( O Figure O 5B O ) O . O The O fact O that O the O four O editing O sites O were O found O either O edited O or O unedited O in O spliced O rps10 O mRNA O is O an O indication O that O editing O does O not O precede O splicing O as O was O previously O found O for O cox2 O in O wheat B ( O 15 O ) O . O It O may O be O argued O that O the O absence O of O splicing O precluded O editing O . O This O possibility O can O be O discarded O since O potato B rps10 O precursor O mRNA O was O found O to O be O edited O in O vivo O ( O 23 O ) O . O These O data O clearly O show O that O splicing O is O not O required O for O rps10 O editing O , O similar O to O previous O findings O for O cox2 O mRNA O and O also O in O cox2 O mutant O derivatives O unable O to O remove O the O intron O ( O 15 O ) O . O This O led O us O to O postulate O that O the O inability O of O wheat B mitochondria O to O recognize O rps10 O editing O sites O is O likely O due O to O the O fact O that O wheat B mitochondria O have O lost O the O editing O trans O - O recognition O elements O which O become O dispensable O after O transfer O of O rps10 O to O the O nucleus O . O To O test O this O possibility O , O rps10 O chimeric O plasmids O containing O editing O site O C259 O from O wheat B cox2 O inserted O either O in O exon1 O or O the O intron O were O constructed O . O Site O C259 O is O formed O by O 23 O nt O corresponding O to O the O - O 16 O / O + O 6 O sequence O embedding O the O target O C O . O Previously O we O found O that O this O small O region O could O be O recognized O by O the O RNA O editing O machinery O when O placed O outside O of O its O natural O context O ( O 16 O , O 17 O ) O . O The O wheat B C259 O editing O site O in O the O chimeric O construct O was O correctly O edited O by O potato B mitochondria O . O This O result O is O not O unexpected O since O the O corresponding O region O in O endogenous O potato B cox2 O mRNA O , O which O presents O two O differences O at O positions O - O 3 O ( O C O instead O of O A O ) O and O - O 7 O ( O G O instead O of O A O ) O , O is O edited O . O Furthermore O , O these O positions O were O not O crucial O for O editing O of O C259 O ( O 17 O ) O . O Surprisingly O , O the O C259 O editing O site O grafted O in O rps10 O was O not O recognized O by O the O wheat B editing O machinery O . O We O cannot O exclude O the O possibility O that O editing O efficiency O in O precursor O molecules O is O very O low O and O so O is O undetectable O when O sequencing O RT O - O PCR O products O representing O a O pool O of O transcripts O . O However O , O analysis O of O the O same O region O in O cox2 O precursors O indicates O that O this O was O not O the O case O since O significant O C O - O to O - O U O conversion O was O observed O ( O Figure O 6D O ) O . O These O observations O lead O us O to O postulate O that O editing O is O occurring O only O when O the O transcript O is O engaged O in O post O - O transcriptional O processing O , O suggesting O that O rps10 O transcripts O are O not O available O to O editing O factors O independently O of O the O RNA O maturation O machinery O . O The O fact O that O the O wheat B editing O site O C259 O inserted O in O chimeric O rps10 O transcripts O was O not O recognized O by O wheat B mitochondria O is O a O strong O argument O for O this O hypothesis O . O One O might O speculate O that O in O plant O mitochondria O , O transcripts O have O to O be O engaged O in O a O kind O of O multiprotein O processing O complex O . O A O failure O to O be O recognized O at O some O early O stage O will O lead O to O their O accumulation O as O unmodified O precursors O . O Rap1p O and O other O transcriptional O regulators O can O function O in O defining O distinct O domains O of O gene O expression O Abstract O Barrier O elements O that O are O able O to O block O the O propagation O of O transcriptional O silencing O in O yeast B are O functionally O similar O to O chromatin O boundary O / O insulator O elements O in O metazoans O that O delimit O functional O chromosomal O domains O . O We O show O that O the O upstream O activating O sequences O of O many O highly O expressed O ribosome O protein O genes O and O glycolytic O genes O exhibit O barrier O activity O . O Analyses O of O these O barriers O indicate O that O binding O sites O for O transcriptional O regulators O Rap1p O , O Abf1p O , O Reb1p O , O Adr1p O and O Gcn4p O may O participate O in O barrier O function O . O We O also O present O evidence O suggesting O that O Rap1p O is O directly O involved O in O barrier O activity O , O and O its O barrier O function O correlates O with O local O changes O in O chromatin O structure O . O We O further O demonstrate O that O tethering O the O transcriptional O activation O domain O of O Rap1p O to O DNA O is O sufficient O to O recapitulate O barrier O activity O .

O Domains O permissive O for O gene O expression O are O usually O defined O as O euchromatin O or O active O chromatin O , O and O domains O that O repress O gene O expression O heterochromatin O or O silent O chromatin O . O The O HML O and O HMR O loci O in O Saccharomyces B cerevisiae I are O silent O chromatin O domains O ( O 1 O ) O . O Compared O to O active O chromatin O , O silent O chromatin O is O more O compact O and O its O histone O components O are O hypoacetylated O ( O 2 O ) O . O The O SIR O complex O consisting O of O Sir2p O through O Sir4p O is O an O integral O part O of O yeast B silent O chromatin O . O Sir3p O and O Sir4p O interact O with O the O N O - O terminal O tails O of O histones O H3 O and O H4 O providing O the O structural O basis O of O silent O chromatin O ( O 1 O ) O . O Sir2p O was O recently O found O to O be O an O NAD O - O dependent O histone O deacetylase O and O was O suggested O to O be O responsible O for O histone O hypoacetylation O in O silent O chromatin O ( O 3 O ) O . O Silent O chromatin O is O initiated O at O small O cis O - O acting O DNA O elements O known O as O the O E O and O I O silencers O flanking O each O of O the O HM O loci O ( O 4 O ) O . O Increasing O evidence O indicates O that O histone O deacetylation O is O key O to O the O propagation O of O silent O chromatin O ( O 4 O ) O . O In O vertebrates O and O fission O yeast B , O spread O of O silent O chromatin O involves O a O chain O of O events O of O histone O H3 O deacetylation O - O - O > O H3 O methylation O - O - O > O binding O of O methylated O H3 O by O HP1 O ( O heterochromatin O protein O 1 O ) O or O swi6 O ( O 4 O ) O . O In O S B . I cerevisiae I , O there O is O evidence O that O Sir3p O ( O hence O the O SIR O complex O ) O has O much O higher O affinity O to O unacetylated O histone O H4 O than O acetylated O H4 O ( O 5 O ) O . O Based O on O this O and O the O fact O that O Sir2p O is O a O histone O deacetylase O , O a O refined O model O for O the O propagation O of O silent O chromatin O can O be O proposed O . O In O this O model O , O Sir2p O recruited O to O the O silencer O deacetylates O histones O in O an O adjacent O nucleosome O enabling O it O to O bind O another O SIR O complex O with O high O affinity O . O The O nucleosome O - O bound O SIR O complex O in O turn O deacetylates O the O neighboring O nucleosome O allowing O it O to O recruit O a O new O SIR O complex O . O In O this O manner O , O the O SIR O complex O promotes O its O own O propagation O along O an O array O of O nucleosomes O ( O 4 O ) O . O The O fact O that O transcriptionally O silent O chromatin O can O encroach O upon O active O chromatin O poses O the O question O of O how O interspersed O domains O of O silent O and O active O chromatin O are O demarcated O . O Studies O of O the O Drosophila O and O vertebrate O genomes O demonstrated O that O some O domains O are O delimited O by O boundary O or O insulator O elements O ( O 6 O ) O . O These O elements O are O specialized O DNA O sequences O that O act O as O barriers O to O enhancers O and O / O or O silent O chromatin O . O One O of O the O best O characterized O insulators O is O the O chicken B HS4 O insulator O at O the O beta O - O globin O locus O . O Histones O surrounding O this O insulator O are O hyperacetylated O indicating O the O presence O of O histone O acetyltransferase O ( O HAT O ) O activity O at O the O insulator O ( O 6 O ) O . O Recently O , O sequences O that O could O block O the O spread O of O silent O chromatin O have O been O discovered O in O S B . I cerevisiae I ( O 7 O , O 8 O ) O . O These O sequences O ( O referred O to O as O silent O chromatin O barriers O ) O include O sub O - O telomeric O anti O - O silencing O regions O ( O STARs O ) O , O the O right O boundary O of O HMR O , O and O the O upstream O activating O sequence O ( O UAS O ) O of O the O highly O expressed O TEF2 O gene O ( O 9 O - O 11 O ) O . O The O mechanisms O underlying O barrier O functions O in O yeast B are O not O known O . O TEF2 O - O UAS O contains O three O tandem O repressor O activator O protein O 1 O ( O Rap1p O ) O - O binding O sites O that O are O necessary O and O sufficient O for O its O barrier O function O ( O 11 O ) O . O Rap1p O is O an O abundant O sequence O - O specific O DNA O - O binding O protein O ( O 12 O ) O . O Variants O of O the O 13 O bp O consensus O sequence O for O Rap1p O binding O ( O ACACC O CRYACAYM O ) O ( O 13 O ) O lie O not O only O in O the O UASs O of O numerous O genes O but O also O in O the O silencers O of O the O HM O loci O and O in O telomeric O C1 O - O 3A O repeats O . O Accordingly O , O Rap1p O functions O as O a O global O regulator O of O transcriptional O activation O and O repression O , O silencing O , O as O well O as O telomere O length O ( O 12 O ) O . O Rap1p O performs O these O diverse O functions O by O interacting O with O different O factors O in O respective O contexts O . O As O an O activator O , O Rap1p O binds O to O the O promoters O of O 362 O ORFs O ( O 13 O ) O and O can O function O via O at O least O three O mechanisms O . O First O , O Rap1p O binding O can O ' O open O up O ' O local O chromatin O structure O at O a O promoter O to O help O another O activator O to O bind O ( O 14 O ) O . O Secondly O , O Rap1p O bound O to O DNA O can O help O Gcr1p O bind O to O an O adjacent O site O in O the O promoter O through O physical O interaction O ( O 15 O ) O . O Thirdly O , O Rap1p O is O involved O in O the O recruitment O of O the O NuA4 O HAT O complex O and O TFIID O to O ribosome O protein O genes O ( O RPGs O ) O ( O 16 O , O 17 O ) O . O As O a O silencing O factor O , O Rap1p O binds O to O silencers O or O telomeric O repeats O and O recruits O Sir3p O / O Sir4p O through O direct O interactions O ( O 18 O ) O . O Rap1p O also O interacts O with O telomere O - O specific O proteins O in O executing O its O role O in O regulating O telomere O length O ( O 19 O ) O . O It O is O puzzling O that O a O protein O that O helps O establish O silent O chromatin O could O also O act O as O a O barrier O to O its O propagation O . O In O this O study O , O we O found O that O in O addition O to O TEF2 O - O UAS O , O UASs O of O many O yeast B genes O exhibit O barrier O activity O . O Analyses O of O these O UASs O indicate O that O binding O sites O for O transcriptional O regulators O Abf1p O , O Reb1p O , O Adr1p O , O Gcn4p O , O as O well O as O Rap1p O , O may O participate O in O barrier O function O . O These O UASs O are O dispersed O across O the O genome O and O might O play O a O role O in O defining O functional O chromosomal O domains O . O Moreover O , O we O demonstrated O that O targeting O the O activation O domain O of O Rap1p O , O Adr1p O or O Gcn4p O alone O , O led O to O barrier O function O . O Since O the O activation O domain O of O an O activator O was O usually O involved O in O interacting O with O co O - O activators O and O / O or O components O of O the O transcriptional O machinery O , O these O data O indicated O that O other O factors O might O also O be O involved O in O barrier O function O . O MATERIALS O AND O METHODS O Plasmids O and O strains O Plasmids O 1 O - O 53 O were O used O to O make O strains O 1 O - O 53 O , O respectively O ( O see O Figs O 1 O - O 6 O ) O .

O RESULTS O UASs O of O many O highly O expressed O genes O can O function O as O barriers O to O the O spread O of O silencing O We O have O previously O shown O that O TEF2 O - O UAS O was O able O to O block O the O spread O of O silencing O in O a O silencer O - O blocking O assay O ( O 11 O ) O . O Such O an O assay O tested O if O a O sequence O had O the O ability O to O prevent O a O silencer O from O silencing O a O reporter O gene O when O it O was O positioned O between O the O silencer O and O the O reporter O . O In O this O report O we O used O a O new O silencer O - O blocking O assay O to O identify O more O barrier O elements O . O This O assay O employed O the O URA3 O gene O and O an O inverted O HML O - O I O that O could O silence O sequences O to O the O right O of O HML O ( O 20 O ) O ( O Fig O . O 1 O , O strain O 1 O ) O . O URA3 O expression O makes O cells O sensitive O to O 5 O - O fluoroorotic O acid O ( O FOA O ) O thus O URA3 O silencing O could O be O measured O by O cell O growth O on O FOA O medium O ( O Fig O . O 1 O , O strain O 1 O ) O . O As O expected O , O TEF2 O - O UAS O and O another O known O barrier O element O , O HMR O - O tRNA O gene O ( O 21 O ) O exhibited O barrier O activity O in O this O assay O as O indicated O by O the O lack O of O silencing O of O URA3 O in O strains O 2 O and O 29 O ( O Fig O . O 1 O ) O . O TEF2 O encoding O translation O elongation O factor O 1 O alpha O is O one O of O the O most O highly O expressed O genes O in O yeast B ( O 27 O ) O . O Other O highly O expressed O genes O include O ribosome O protein O genes O ( O RPGs O ) O and O genes O coding O for O glycolytic O enzymes O ( O 27 O ) O . O The O coordinated O regulation O of O most O of O these O genes O requires O the O so O - O called O general O regulatory O factors O Rap1p O , O Abf1p O and O Reb1p O ( O 28 O , O 29 O ) O . O Using O the O above O silencer O - O blocking O assay O , O we O tested O if O the O UASs O of O other O highly O expressed O genes O could O also O block O URA3 O silencing O ( O Fig O . O 1 O ) O . O Seventeen O new O barrier O elements O were O identified O from O a O total O of O 26 O UASs O tested O . O These O 17 O elements O were O UASs O of O eight O RPGs O ( O see O Fig O . O 1 O , O strains O 3 O - O 10 O ) O , O eight O glycolytic O genes O ( O strains O 18 O - O 25 O ) O and O the O HIS3 O gene O ( O strain O 26 O ) O . O All O 17 O elements O except O ADH2 O - O UAS O and O HIS3 O - O UAS O exhibited O very O strong O barrier O activity O as O evidenced O by O the O absence O of O URA3 O - O silencing O in O strains O 3 O - O 10 O and O 18 O - O 24 O ( O Fig O . O 1 O ) O . O Seven O of O the O eight O RPG O - O UASs O that O had O barrier O activity O , O contained O a O single O or O a O pair O of O tandem O Rap1p O - O binding O sites O ( O Fig O . O 1 O , O strains O 3 O - O 9 O ) O . O Three O of O them O also O contained O an O Abf1p O or O Reb1p O site O ( O strains O 6 O , O 8 O and O 9 O ) O . O One O barrier O RPG O - O UAS O ( O strain O 10 O ) O had O only O a O predicted O Abf1p O site O . O Of O the O seven O RPG O - O UASs O that O had O no O barrier O activity O ( O Fig O . O 1 O , O 11 O - O 17 O ) O , O only O two O bore O no O site O for O Rap1p O , O Abf1p O or O Reb1p O ( O 11 O and O 12 O ) O . O The O remaining O five O each O contained O one O to O three O Rap1p O sites O ( O strains O 13 O - O 17 O ) O . O RPL15A O - O UAS O ( O 17 O ) O also O contained O an O Abf1p O site O . O For O most O of O the O 15 O RPG O - O UASs O tested O ( O 3 O - O 17 O ) O , O the O presence O or O absence O of O predicted O Rap1p O sites O correlated O with O the O presence O or O absence O of O Rap1p O association O in O vivo O as O previously O examined O by O chromatin O immunoprecipitation O assays O ( O 13 O ) O . O Exceptions O were O the O UASs O of O RPS24B O , O RPS28A O and O RPL15A O ( O 13 O ) O . O Of O the O eight O UASs O of O glycolytic O genes O tested O ( O Fig O . O 1 O , O strains O 18 O - O 25 O ) O , O seven O exhibited O strong O barrier O activity O ( O 18 O - O 24 O ) O and O one O had O weaker O but O detectable O barrier O activity O ( O strain O 25 O ) O . O Glycolytic O genes O are O among O the O most O highly O expressed O genes O and O their O high O expression O depends O on O the O functions O of O Rap1p O , O Abf1p O or O Reb1p O as O well O as O Gcr1p O ( O 29 O , O 30 O ) O . O The O seven O strong O glycolytic O barriers O all O consist O of O one O or O two O Rap1p O sites O plus O one O or O two O Reb1p O or O Abf1p O sites O ( O Fig O . O 1 O , O strains O 18 O - O 24 O ) O . O In O addition O , O one O or O more O Gcr1p O - O binding O sites O are O found O adjacent O to O each O Rap1p O site O . O It O was O proposed O that O the O function O of O Rap1p O was O to O facilitate O the O binding O of O Gcr1p O to O the O UAS O ( O 15 O ) O . O Abf1p O or O Reb1p O was O shown O to O play O a O role O similar O to O that O of O Rap1p O in O activating O glycolytic O genes O ( O 31 O - O 33 O ) O . O Although O the O above O data O reinforced O the O notion O that O certain O Rap1p O - O binding O UASs O could O serve O as O barriers O to O silencing O , O they O raised O new O questions O about O the O essential O components O of O a O barrier O element O . O For O example O , O some O of O the O UASs O that O contained O only O a O single O Rap1p O site O had O barrier O activity O ( O e O . O g O . O RPL19B O - O UAS O , O strain O 3 O ) O whereas O others O that O contained O two O or O three O sites O had O no O activity O ( O e O . O g O . O RPL39 O , O strain O 16 O ) O . O One O explanation O was O that O sequences O flanking O the O Rap1p O site O ( O s O ) O in O a O particular O UAS O could O positively O or O negatively O influence O barrier O function O . O Moreover O , O the O presence O of O Abf1p O or O Reb1p O sites O in O 11 O of O the O 17 O new O barriers O made O us O wonder O if O they O also O participated O in O barrier O function O . O We O began O to O address O these O issues O by O analyzing O three O new O barrier O elements O ( O Fig O . O 2 O ) O . O RPS10A O - O UAS O containing O an O Abf1p O - O binding O site O and O a O pair O of O Rap1p O sites O was O divided O into O three O fragments O that O were O tested O in O a O silencer O - O blocking O assay O ( O Fig O . O 2 O , O strains O 30 O - O 32 O ) O . O It O was O clear O that O only O the O fragment O containing O Rap1p O sites O functioned O as O a O barrier O ( O strain O 31 O ) O . O TPI1 O - O UAS O bearing O a O Reb1p O site O and O a O Rap1p O site O was O divided O into O two O parts O with O one O containing O the O Rap1p O site O ( O Fig O . O 2 O , O strain O 34 O ) O and O the O other O Reb1p O site O ( O strain O 33 O ) O . O Neither O of O these O fragments O alone O retained O barrier O activity O indicating O that O concerted O action O of O Reb1p O and O Rap1p O was O required O for O barrier O activity O . O Duplicating O the O Reb1p O - O bearing O part O of O TPI1 O - O UAS O didn O ' O t O restore O barrier O activity O ( O strain O 35 O ) O . O However O , O triplicating O the O Rap1p O - O containing O part O did O re O - O create O barrier O function O ( O strain O 36 O ) O . O RPS28A O - O UAS O bore O , O in O addition O to O a O Rap1p O site O , O an O Abf1p O site O and O an O adjacent O T O - O rich O region O that O are O required O for O efficient O transcription O of O RPS28A O ( O 34 O ) O . O A O sequence O of O RPS28A O - O UAS O deleted O for O a O fragment O bearing O the O Rap1p O site O lost O the O barrier O activity O ( O Fig O . O 2 O , O strain O 37 O ) O . O However O , O duplicating O this O sequence O restored O barrier O activity O ( O strain O 38 O ) O . O The O above O results O indicated O again O that O Rap1p O sites O could O form O barriers O ( O strains O 31 O and O 36 O ) O . O On O the O other O hand O , O they O also O suggested O that O synergistic O actions O of O Abf1p O sites O ( O strain O 38 O ) O , O Reb1p O site O + O Rap1p O site O ( O strain O 18 O ) O , O or O Abf1p O site O + O Rap1p O site O ( O strain O 16 O ) O could O all O lead O to O barrier O function O . O This O was O not O very O surprising O since O Rap1p O , O Abf1p O and O Reb1p O could O perform O similar O and O sometimes O interchangeable O functions O in O gene O regulation O ( O 16 O , O 35 O , O 36 O ) O . O Note O , O however O , O we O haven O ' O t O ruled O out O the O possibility O that O other O factors O ( O e O . O g O . O Gcr1p O ) O or O structure O features O of O DNA O ( O e O . O g O . O T O - O tracks O ) O were O also O involved O in O barrier O function O . O It O was O interesting O that O ADH2 O - O UAS O and O HIS3 O - O UAS O bearing O no O site O for O Rap1p O , O Abf1p O or O Reb1p O exhibited O detectable O barrier O activity O ( O Fig O . O 1 O , O strains O 25 O and O 26 O ) O . O However O , O binding O sites O for O other O transcriptional O activators O existed O in O these O UASs O . O The O major O regulator O that O binds O to O ADH2 O - O UAS O is O Adr1p O ( O 37 O ) O . O On O the O other O hand O , O Gcn4p O binds O to O multiple O sites O in O HIS3 O - O UAS O and O activates O HIS3 O transcription O ( O 38 O ) O . O The O possible O involvement O of O Adr1p O or O Gcn4p O in O barrier O function O was O examined O below O . O Note O Adr1p O function O was O subject O to O glucose O repression O ( O 37 O ) O , O which O might O explain O why O ADH2 O - O UAS O only O exhibited O limited O barrier O activity O since O glucose O was O used O in O the O media O used O in O our O assay O . O Effect O of O mutating O Rap1p O - O binding O sites O in O TEF2 O - O UAS O on O barrier O function O Although O we O had O shown O that O the O three O Rap1p O - O binding O sites O in O TEF2 O - O UAS O were O necessary O and O sufficient O for O its O barrier O activity O ( O 11 O ) O , O we O had O not O shown O if O binding O of O Rap1p O to O these O sites O was O required O . O To O address O this O we O performed O mutational O analysis O of O TEF2 O - O UAS O . O As O shown O in O Figure O 3A O and O B O , O the O three O Rap1p O - O binding O sites O in O TEF2 O - O UAS O ( O designated O as O R1 O , O R2 O and O R3 O ) O were O all O able O to O bind O Rap1p O in O an O EMSA O ( O Fig O . O 3B O ) O . O Single O or O double O C O - O - O > O A O mutations O were O introduced O into O R1 O , O R2 O and O R3 O resulting O in O m1 O , O m2 O and O m3 O , O respectively O ( O Fig O . O 3A O ) O . O The O m2 O and O m3 O sites O had O both O lost O the O ability O to O bind O Rap1p O , O whereas O m1 O still O bound O Rap1p O ( O Fig O . O 3B O ) O , O which O could O be O predicted O from O the O specific O mutations O in O each O site O ( O Fig O . O 3A O , O compare O m1 O , O m2 O and O m3 O to O the O consensus O sequence O ) O . O We O then O tested O a O mutated O TEF2 O - O UAS O containing O m1 O , O m2 O and O m3 O in O a O silencer O - O blocking O assay O using O the O HML O - O E O silencer O and O the O HML O alpha O genes O ( O Fig O . O 3C O ) O . O In O this O assay O , O the O HML O - O I O silencer O was O deleted O but O the O HML O - O E O silencer O was O sufficient O to O silence O the O HML O alpha O genes O ( O Fig O . O 3C O , O strain O 39 O ) O ( O 11 O ) O . O Silencing O in O strain O 39 O ( O a O - O type O ) O was O measured O by O its O ability O to O mate O with O an O alpha O - O type O strain O ( O Fig O . O 3C O ) O . O As O predicted O , O the O wild O - O type O TEF2 O - O UAS O blocked O HML O alpha O silencing O ( O 11 O ) O ( O Fig O . O 3C O , O strain O 40 O ) O . O On O the O other O hand O , O the O mutated O TEF2 O - O UAS O containing O m1 O , O m2 O and O m3 O had O lost O barrier O activity O ( O Fig O . O 3C O , O compare O the O mating O efficiencies O of O strains O 41 O and O 40 O ) O . O Therefore O , O mutations O that O prevented O Rap1p O from O binding O two O of O the O three O sites O in O TEF2 O - O UAS O abolished O its O barrier O activity O , O indicating O that O association O of O Rap1p O with O TEF2 O - O UAS O at O more O than O one O site O was O required O for O barrier O function O . O The O barrier O TEF2 O - O UAS O alters O local O chromatin O structure O In O eukaryotic O cells O , O the O topology O of O local O DNA O reflects O the O chromatin O structure O in O which O it O resides O . O We O had O previously O developed O a O DNA O topology O - O based O assay O to O examine O chromatin O structure O in O vivo O , O which O involved O excising O a O chromosomal O region O of O interest O from O its O genomic O location O as O a O circle O using O site O - O specific O recombination O ( O 39 O ) O . O Using O this O strategy O , O we O demonstrated O that O DNA O in O silenced O chromatin O was O more O negatively O supercoiled O than O that O in O active O chromatin O ( O 39 O ) O . O In O this O report O we O used O the O topology O assay O to O address O if O barrier O elements O altered O local O chromatin O structure O as O Drosophila B or O chicken B insulators O did O ( O 40 O , O 41 O ) O . O Various O sequences O ( O designated O X O ) O from O UASs O of O TEF2 O , O AgTEF O ( O TEF O gene O from O Ashbya B gossypii I ) O and O ADE2 O were O inserted O between O HML O - O E O and O HML O alpha O at O HML O Delta O I O ( O HML O locus O deleted O for O the O I O silencer O ) O flanked O by O the O FRT O sites O for O the O Flp1p O site O - O specific O recombinase O ( O Fig O . O 4A O and O B O ) O . O The O FLP1 O gene O was O under O the O control O of O the O inducible O GAL10 O promoter O ( O 39 O ) O . O The O mating O efficiency O of O each O strain O measured O silencing O of O HML O alpha O ( O Fig O . O 4C O ) O . O In O strains O 40 O , O 42 O , O 44 O and O 47 O , O silencing O was O restricted O to O the O left O of O the O X O insertions O and O HML O alpha O was O derepressed O ( O Fig O . O 4C O ) O . O Consistently O , O the O proportion O of O silent O chromatin O in O the O region O flanked O by O the O FRT O sites O in O each O of O these O strains O was O decreased O , O as O indicated O by O the O reduced O negative O supercoiling O of O the O excised O circle O ( O 11 O ) O ( O data O not O shown O ) O . O Note O that O the O above O effect O of O a O barrier O on O HML O chromatin O reflected O both O change O in O the O scope O of O silencing O caused O by O the O barrier O activity O and O alteration O ( O if O any O ) O in O chromatin O structure O at O the O barrier O independent O of O the O silencing O state O of O the O locus O . O To O exclusively O examine O the O latter O , O we O analyzed O the O topology O of O HML O DNA O in O a O silencing O - O deficient O background O . O The O SIR3 O gene O in O strains O described O in O Figure O 4B O was O disrupted O rendering O them O defective O in O silencing O ( O strains O 40 O ' O - O 48 O ' O in O Fig O . O 4D O ) O . O Recombination O mediated O by O Flp1p O in O these O strains O led O to O the O excision O of O a O group O of O chromosomal O circles O that O differed O only O in O the O X O insertion O . O The O supercoiling O of O these O circles O was O analyzed O as O a O function O of O the O length O of O the O insertion O ( O Fig O . O 4D O ) O . O If O an O insertion O simply O lengthened O a O circle O without O causing O abnormal O changes O in O nucleosomal O structure O and O / O or O density O , O the O topoisomers O of O this O circle O would O migrate O slower O relative O to O those O of O a O similar O circle O with O a O smaller O size O . O Otherwise O , O migration O of O the O topoisomers O would O deviate O from O that O predicted O based O on O the O size O of O the O circle O . O As O shown O in O Figure O 4D O , O the O circle O from O strain O 40 O ' O bearing O a O 104 O bp O barrier O element O migrated O faster O rather O than O slower O than O the O circle O from O strain O 46 O ' O bearing O a O 91 O bp O non O - O barrier O element O . O Circles O bearing O other O barrier O elements O also O exhibited O unexpected O faster O migration O ( O compare O strains O 44 O ' O to O 45 O ' O , O 47 O ' O to O 43 O ' O , O 42 O ' O to O 48 O ' O , O respectively O ) O . O Therefore O , O these O data O indicated O that O barrier O function O correlated O with O altered O topology O of O local O DNA O . O This O was O further O demonstrated O by O that O mutations O in O TEF2 O - O UAS O that O abolished O its O barrier O activity O also O abolished O its O effect O on O DNA O topology O ( O Fig O . O 4D O , O compare O 41 O ' O to O 40 O ' O ; O note O that O circles O from O both O strains O had O the O same O size O ) O . O Since O in O our O gel O assay O more O negatively O supercoiled O DNA O migrate O slower O , O we O concluded O that O every O fragment O with O barrier O activity O caused O a O reduction O in O negative O supercoiling O of O approximately O one O to O two O turns O in O HML O Delta O I O DNA O ( O Fig O . O 4D O , O compare O the O centers O of O distributions O of O topoisomers O in O pairs O of O lanes O , O e O . O g O . O 40 O ' O and O 41 O ' O ) O . O The O topology O of O eukaryotic O DNA O reflects O mainly O the O wrapping O of O DNA O into O nucleosomes O ( O approximately O one O negative O superhelical O turn O is O associated O with O each O nucleosome O ) O ( O 42 O ) O . O Therefore O , O removal O of O one O nucleosome O would O eliminate O approximately O one O turn O . O On O the O other O hand O , O histone O acetylation O can O reduce O negative O supercoiling O associated O with O a O nucleosome O by O approximately O 0 O . O 2 O turns O ( O 43 O ) O . O Therefore O , O acetylating O five O nucleosomes O would O reduce O negative O supercoiling O by O approximately O one O turn O . O Consequently O , O the O linking O number O change O of O one O to O two O brought O about O by O TEF2 O - O UAS O can O be O accounted O for O by O either O the O loss O of O one O to O two O nucleosomes O or O acetylation O of O five O to O 10 O nucleosomes O . O Further O experiments O are O under O way O to O clarify O the O nature O of O change O in O chromatin O induced O by O a O barrier O . O Targeting O the O transcription O activation O domain O of O Rap1p O recapitulates O its O barrier O activity O The O multifunctional O Rap1p O can O be O divided O into O at O least O four O functional O domains O ( O Fig O . O 5A O ) O ( O 12 O ) O . O We O were O interested O in O defining O which O of O these O domains O might O be O involved O in O the O barrier O activity O of O Rap1p O . O To O this O end O , O we O fused O various O parts O of O Rap1p O to O the O bacterial O LexA O protein O and O tested O if O targeting O any O of O the O fusion O proteins O to O LexA O - O binding O sites O could O re O - O create O a O barrier O to O silencing O ( O Fig O . O 5A O ) O . O The O LexA O - O RAP1 O fusion O genes O were O carried O on O 2 O micro O m O based O plasmids O marked O by O LEU2 O ( O designated O L1 O - O L6 O , O Fig O . O 5A O ) O . O When O introduced O into O strain O 50 O in O which O two O LexA O - O binding O sites O had O been O inserted O between O the O inverted O HML O - O I O and O URA3 O , O LexA O alone O had O no O effect O on O URA3 O silencing O ( O Fig O . O 5A O , O plasmid O L1 O ) O . O Targeting O the O DNA O binding O domain O , O DNA O bending O domain O , O silencing O domain O , O or O the O activating O + O silencing O domain O of O Rap1p O also O did O not O affect O URA3 O silencing O ( O L2 O - O L5 O ) O . O On O the O other O hand O , O targeting O the O activation O domain O alone O recapitulated O the O barrier O activity O of O Rap1p O ( O L6 O ) O . O These O results O indicated O that O the O activation O domain O of O Rap1p O was O involved O in O barrier O activity O . O The O inability O of O the O Rap1p O - O silencing O domain O to O block O URA3 O silencing O in O our O assay O did O not O necessarily O mean O that O this O domain O had O no O barrier O function O , O since O such O a O function O might O be O suppressed O by O much O stronger O silencing O activity O associated O with O the O silencing O domain O . O Was O the O lack O of O barrier O function O of O fusion O constructs O L2 O - O L5 O due O to O a O lack O of O expression O of O these O proteins O ? O To O address O this O possibility O , O we O examined O the O levels O of O L1 O - O L6 O proteins O as O well O as O L7 O and O L8 O proteins O described O in O Figure O 5B O by O western O blotting O using O an O antibody O against O LexA O . O As O shown O in O Figure O 5C O , O L5 O was O expressed O at O a O level O comparable O to O L6 O , O and O L4 O was O expressed O at O a O higher O level O than O L6 O . O Therefore O , O the O lack O of O barrier O function O of O L4 O and O L6 O was O not O the O result O of O their O lack O of O expression O . O On O the O other O hand O , O the O level O of O L2 O or O L3 O was O significantly O lower O than O that O of O L6 O , O hence O the O lack O of O barrier O function O of O L2 O and O L3 O might O be O due O to O their O insufficient O expression O . O As O an O important O control O for O the O above O targeting O experiments O , O we O showed O that O plasmids O L1 O - O L6 O ( O Fig O . O 5A O ) O as O well O as O L7 O and O L8 O ( O Fig O . O 5B O ) O bearing O LexA O - O fusion O genes O had O no O effect O on O URA3 O silencing O in O strain O 1 O ( O Fig O . O 1 O ) O in O which O there O was O no O binding O site O for O LexA O present O between O HML O - O I O and O URA3 O ( O data O not O shown O ) O . O Hence O , O the O effect O of O the O fusion O proteins O on O URA3 O silencing O was O the O result O of O their O targeting O to O specific O loci O , O not O the O consequence O of O non O - O specific O , O indirect O functions O ( O if O any O ) O of O these O proteins O . O Targeted O activation O domain O of O Adr1p O or O Gcn4p O can O also O act O as O a O barrier O factor O We O have O shown O above O that O ADH2 O - O UAS O bearing O Adr1p O - O binding O sites O and O HIS3 O - O UAS O bearing O Gcn4p O sites O both O had O detectable O barrier O activity O ( O Fig O . O 1 O , O strains O 25 O and O 26 O ) O . O Given O that O tethering O the O activation O domain O of O Rap1p O is O sufficient O for O barrier O function O , O we O tested O if O targeting O the O activation O domain O of O Adr1p O or O Gcn4p O could O also O establish O a O barrier O . O Adr1p O contains O four O separate O activation O domains O ( O TADI O - O TADIV O ) O that O can O contact O Ada2p O , O Gcn5p O and O / O or O TFIIB O ( O 45 O ) O . O TAD O III O ( O 415 O - O 467 O ) O interacts O with O only O Gcn5p O but O not O Ada2p O or O TFIIB O . O We O fused O this O domain O of O Adr1p O and O the O activation O domain O of O Gcn4p O ( O 102 O - O 149 O ) O to O LexA O , O respectively O ( O Fig O . O 5B O , O L7 O and O L8 O ) O . O Targeting O these O fusion O proteins O to O two O LexA O - O binding O sites O between O HML O - O I O and O URA3 O in O strain O 50 O dramatically O reduced O URA3 O silencing O ( O Fig O . O 5B O , O compare O L7 O and O L8 O to O L1 O ) O . O Therefore O , O like O LexA O - O Rap1p O ( O 627 O - O 695 O ) O , O both O LexA O - O Adr1p O ( O 415 O - O 467 O ) O and O LexA O - O Gcn4p O ( O 102 O - O 149 O ) O also O had O barrier O activity O . O Barrier O function O of O these O fusion O proteins O was O significantly O decreased O in O strain O 51 O in O which O only O one O LexA O site O was O inserted O between O HML O - O I O and O URA3 O ( O compare O strains O 50 O and O 51 O carrying O plasmid O L7 O ) O , O indicating O that O the O potency O of O such O barriers O was O dependent O on O the O amount O of O tethered O fusion O proteins O . O DISCUSSION O We O have O shown O in O this O report O that O UASs O of O many O highly O expressed O genes O could O function O as O barriers O to O the O spread O of O transcriptional O silencing O . O These O newly O identified O barrier O elements O together O with O previously O described O barrier O elements O ( O STARs O , O HMR O - O tRNA O gene O , O TEF2 O - O UAS O and O CHA1 O - O UAS O ) O ( O 9 O - O 11 O , O 21 O ) O are O scattered O across O the O yeast B genome O and O may O play O a O role O in O dividing O the O genome O into O functional O domains O . O Analyses O of O the O barrier O UASs O suggest O that O binding O sites O for O transcriptional O regulators O Rap1p O , O Abf1p O , O Reb1p O , O Adr1p O and O Gcn4p O can O participate O in O barrier O function O . O Barrier O activity O often O requires O concerted O actions O of O more O than O one O factor O - O binding O site O . O Our O mutational O analysis O of O TEF2 O - O UAS O suggests O a O direct O involvement O of O Rap1p O in O its O barrier O function O . O It O is O noteworthy O that O not O all O UASs O of O highly O expressed O genes O have O barrier O activity O . O Many O non O - O barrier O UASs O also O consist O of O multiple O regulator O binding O sites O , O therefore O other O unknown O factors O might O determine O whether O a O UAS O could O act O as O a O barrier O . O How O Rap1p O and O the O other O transcriptional O regulators O act O to O block O silencing O is O not O clear O . O Since O they O can O all O act O as O transcriptional O activators O , O one O natural O explanation O is O that O they O may O overcome O the O silencing O effect O of O a O silencer O and O directly O activate O the O reporter O gene O . O However O , O it O has O been O well O documented O that O Rap1p O and O the O other O transcriptional O regulators O usually O act O at O relatively O short O distances O ( O less O than O ~ O 600 O bp O upstream O of O the O translation O start O codon O ) O ( O 28 O , O 29 O , O 46 O ) O , O but O the O binding O sites O for O these O regulators O were O > O 800 O bp O from O the O translation O start O codon O in O most O of O the O silencing O - O blocking O tests O in O this O report O ( O Figs O 1 O and O 2 O ) O . O In O the O test O shown O in O Figure O 6 O , O TEF2 O - O UAS O blocked O ADE2 O silencing O when O it O was O ~ O 2 O kb O downstream O from O the O translation O start O codon O of O the O gene O . O Moreover O , O Fourel O et O al O . O ( O 44 O ) O demonstrated O that O the O barrier O function O ( O or O anti O - O silencing O function O ) O of O an O activator O was O independent O of O its O role O in O activating O transcription O . O Therefore O , O it O is O unlikely O that O the O ability O of O a O UAS O to O prevent O gene O silencing O is O due O to O its O direct O activation O of O the O gene O . O In O light O of O this O , O our O results O are O in O agreement O with O the O notion O that O transcriptional O regulators O can O also O participate O in O defining O the O boundaries O of O functional O chromosomal O domains O . O A O few O models O have O been O proposed O for O the O barrier O functions O of O transcriptional O regulators O . O One O model O proposed O that O binding O of O a O regulator O to O a O barrier O led O to O the O formation O of O a O nucleosome O - O free O region O thereby O disrupting O a O continuous O nucleosome O array O ( O 11 O ) O . O Since O the O SIR O complexes O spread O by O self O - O interaction O and O interacting O with O adjacent O nucleosmes O in O a O stepwise O fashion O ( O 4 O ) O , O a O nucleosome O - O free O gap O could O present O a O barrier O to O the O spreading O SIR O complex O . O This O ' O nucleosome O gap O ' O hypothesis O is O consistent O with O that O certain O barrier O factors O such O as O Rap1p O and O Reb1p O could O indeed O prevent O nucleosome O formation O around O their O binding O sites O ( O 14 O ) O and O the O barrier O function O of O TEF2 O - O UAS O correlated O with O its O ability O to O alter O local O chromatin O structure O ( O this O report O ) O . O In O fact O , O many O insulator O / O boundary O elements O in O higher O organisms O have O also O been O shown O to O alter O local O chromatin O structure O . O For O instance O , O the O chicken B beta O - O globin O insulator O was O linked O to O changes O in O nucleosome O positioning O , O and O the O Drosophila B scs O and O scs O ' O boundary O elements O are O associated O with O unusual O chromatin O structures O that O are O hypersensitive O to O nucleases O ( O 40 O , O 41 O ) O . O However O , O it O is O not O clear O whether O any O chromatin O change O associated O with O barrier O function O in O yeast B or O insulator O function O in O higher O cells O is O the O cause O or O effect O of O the O function O . O Another O model O for O barrier O action O proposed O by O R O . O Kamakaka O and O colleagues O ( O 21 O ) O proposed O that O barrier O factors O recruit O chromatin O modifying O and O / O or O remodeling O complexes O to O counteract O the O more O compact O , O hypoacetylated O silent O chromatin O . O In O agreement O with O this O hypothesis O , O targeted O HATs O SAS2 O , O GCN5 O and O ESA1 O all O had O barrier O activity O ( O 21 O ; O Y O . O - O H O . O Chiu O , O Q O . O Yu O and O X O . O Bi O , O unpublished O results O ) O . O Interestingly O , O Rap1p O , O Adr1p O , O Gcn4p O and O Abf1p O share O the O ability O to O recruit O HAT O complexes O NuA4 O and O / O or O SAGA O to O target O genes O ( O 16 O , O 45 O , O 47 O - O 49 O ) O . O Therefore O , O these O factors O that O are O capable O of O binding O to O the O newly O identified O barriers O may O function O as O barrier O factors O by O recruiting O HAT O complexes O . O In O fact O , O recruitment O of O HAT O activity O has O also O been O suggested O to O be O the O mechanism O underlying O the O function O of O the O chicken B beta O - O globin O insulator O ( O 6 O ) O , O although O it O was O not O known O what O HAT O might O be O involved O . O Our O demonstration O that O tethering O the O activation O domain O of O Rap1p O , O Adr1p O or O Gcn4p O alone O recapitulates O barrier O activity O is O consistent O with O the O above O HAT O model O for O barrier O function O , O since O at O least O the O activation O domain O of O Adr1p O has O been O shown O to O directly O interact O with O HAT O complexes O ( O 45 O ) O . O However O , O we O haven O ' O t O ruled O out O the O possibility O that O the O barrier O function O of O the O targeted O activation O domain O of O Rap1p O , O Adr1p O or O Gcn4p O is O not O related O to O the O barrier O function O of O the O native O protein O . O Note O that O the O ' O nucleosome O gap O ' O model O and O the O HAT O model O are O not O mutually O exclusive O since O the O nucleosome O gap O could O result O from O destabilization O of O nucelosomes O caused O by O HAT O function O . O A O recent O intriguing O study O showed O that O targeting O proteins O of O the O nuclear O pore O complex O ( O NPC O ) O could O also O establish O a O boundary O for O silent O chromatin O , O and O that O tethering O to O NPC O was O required O for O boundary O activity O ( O 50 O ) O . O This O led O to O a O revisit O to O the O looping O model O for O the O function O of O boundary O / O insulator O elements O ( O 51 O ) O . O However O , O an O alternative O explanation O was O that O the O NPC O compartment O could O simply O be O rich O in O transcriptional O activating O factors O or O poor O in O silencing O factors O like O the O SIR O proteins O ( O 50 O ) O . O In O summary O , O results O from O this O and O other O studies O indicate O that O factors O previously O identified O as O positive O and O / O or O negative O regulators O of O gene O activation O could O also O function O in O demarcating O distinct O domains O of O gene O activity O . O How O these O factors O carry O out O their O boundary O function O is O not O resolved O but O recruitment O of O other O factors O ( O e O . O g O . O chromatin O modifying O complexes O ) O is O likely O to O be O involved O .

O Methods O The O Blue O Mountains O Eye O Study O ( O BMES O ) O is O a O population O - O based O cohort O study O of O common O eye O diseases O and O other O health O outcomes O . O The O study O involved O eligible O permanent O residents O aged O 49 O years O and O older O , O living O in O two O postcode O areas O in O the O Blue O Mountains O , O west O of O Sydney O , O Australia O .

O Cortical O cataract O and O PSC O were O assessed O from O the O retroillumination O photographs O by O estimating O the O percentage O of O the O circular O grid O involved O . O Cortical O cataract O was O defined O when O cortical O opacity O involved O at O least O 5 O % O of O the O total O lens O area O .

O Data O analysis O was O performed O using O the O Statistical O Analysis O System O ( O SAS O , O SAS O Institute O , O Cary O , O NC O , O USA O ) O . O Age O - O adjusted O prevalence O was O calculated O using O direct O standardization O of O the O cross O - O section O II O population O to O the O cross O - O section O I O population O .

O Discussion O Findings O from O two O surveys O of O BMES O cross O - O sectional O populations O with O similar O age O and O gender O distribution O showed O that O the O prevalence O of O cortical O cataract O and O PSC O remained O stable O , O while O the O prevalence O of O nuclear O cataract O appeared O to O have O increased O . O Comparison O of O age O - O specific O prevalence O , O with O totally O independent O samples O within O each O age O group O , O confirmed O the O robustness O of O our O findings O from O the O two O survey O samples O . O Although O lens O photographs O taken O from O the O two O surveys O were O graded O for O nuclear O cataract O by O the O same O graders O , O who O documented O a O high O inter O - O and O intra O - O grader O reliability O , O we O cannot O exclude O the O possibility O that O variations O in O photography O , O performed O by O different O photographers O , O may O have O contributed O to O the O observed O difference O in O nuclear O cataract O prevalence O . O However O , O the O overall O prevalence O of O any O cataract O ( O including O cataract O surgery O ) O was O relatively O stable O over O the O 6 O - O year O period O . O Although O different O population O - O based O studies O used O different O grading O systems O to O assess O cataract O [ O 15 O ] O , O the O overall O prevalence O of O the O three O cataract O types O were O similar O across O different O study O populations O [ O 12 O , O 16 O - O 23 O ] O . O Most O studies O have O suggested O that O nuclear O cataract O is O the O most O prevalent O type O of O cataract O , O followed O by O cortical O cataract O [ O 16 O - O 20 O ] O . O Ours O and O other O studies O reported O that O cortical O cataract O was O the O most O prevalent O type O [ O 12 O , O 21 O - O 23 O ] O . O Our O age O - O specific O prevalence O data O show O a O reduction O of O 15 O . O 9 O % O in O cortical O cataract O prevalence O for O the O 80 O - O 84 O year O age O group O , O concordant O with O an O increase O in O cataract O surgery O prevalence O by O 9 O % O in O those O aged O 80 O + O years O observed O in O the O same O study O population O [ O 10 O ] O . O Although O cortical O cataract O is O thought O to O be O the O least O likely O cataract O type O leading O to O a O cataract O surgery O , O this O may O not O be O the O case O in O all O older O persons B . O A O relatively O stable O cortical O cataract O and O PSC O prevalence O over O the O 6 O - O year O period O is O expected O . O We O cannot O offer O a O definitive O explanation O for O the O increase O in O nuclear O cataract O prevalence O . O A O possible O explanation O could O be O that O a O moderate O level O of O nuclear O cataract O causes O less O visual O disturbance O than O the O other O two O types O of O cataract O , O thus O for O the O oldest O age O groups O , O persons B with O nuclear O cataract O could O have O been O less O likely O to O have O surgery O unless O it O is O very O dense O or O co O - O existing O with O cortical O cataract O or O PSC O . O Previous O studies O have O shown O that O functional O vision O and O reading O performance O were O high O in O patients B undergoing O cataract O surgery O who O had O nuclear O cataract O only O compared O to O those O with O mixed O type O of O cataract O ( O nuclear O and O cortical O ) O or O PSC O [ O 24 O , O 25 O ] O . O In O addition O , O the O overall O prevalence O of O any O cataract O ( O including O cataract O surgery O ) O was O similar O in O the O two O cross O - O sections O , O which O appears O to O support O our O speculation O that O in O the O oldest O age O group O , O nuclear O cataract O may O have O been O less O likely O to O be O operated O than O the O other O two O types O of O cataract O . O This O could O have O resulted O in O an O increased O nuclear O cataract O prevalence O ( O due O to O less O being O operated O ) O , O compensated O by O the O decreased O prevalence O of O cortical O cataract O and O PSC O ( O due O to O these O being O more O likely O to O be O operated O ) O , O leading O to O stable O overall O prevalence O of O any O cataract O . O Possible O selection O bias O arising O from O selective O survival O among O persons B without O cataract O could O have O led O to O underestimation O of O cataract O prevalence O in O both O surveys O . O We O assume O that O such O an O underestimation O occurred O equally O in O both O surveys O , O and O thus O should O not O have O influenced O our O assessment O of O temporal O changes O . O Measurement O error O could O also O have O partially O contributed O to O the O observed O difference O in O nuclear O cataract O prevalence O . O Assessment O of O nuclear O cataract O from O photographs O is O a O potentially O subjective O process O that O can O be O influenced O by O variations O in O photography O ( O light O exposure O , O focus O and O the O slit O - O lamp O angle O when O the O photograph O was O taken O ) O and O grading O . O Although O we O used O the O same O Topcon O slit O - O lamp O camera O and O the O same O two O graders O who O graded O photos O from O both O surveys O , O we O are O still O not O able O to O exclude O the O possibility O of O a O partial O influence O from O photographic O variation O on O this O result O . O A O similar O gender O difference O ( O women B having O a O higher O rate O than O men B ) O in O cortical O cataract O prevalence O was O observed O in O both O surveys O . O Our O findings O are O in O keeping O with O observations O from O the O Beaver O Dam O Eye O Study O [ O 18 O ] O , O the O Barbados O Eye O Study O [ O 22 O ] O and O the O Lens O Opacities O Case O - O Control O Group O [ O 26 O ] O . O It O has O been O suggested O that O the O difference O could O be O related O to O hormonal O factors O [ O 18 O , O 22 O ] O . O A O previous O study O on O biochemical O factors O and O cataract O showed O that O a O lower O level O of O iron O was O associated O with O an O increased O risk O of O cortical O cataract O [ O 27 O ] O . O No O interaction O between O sex O and O biochemical O factors O were O detected O and O no O gender O difference O was O assessed O in O this O study O [ O 27 O ] O . O The O gender O difference O seen O in O cortical O cataract O could O be O related O to O relatively O low O iron O levels O and O low O hemoglobin O concentration O usually O seen O in O women B [ O 28 O ] O . O Diabetes O is O a O known O risk O factor O for O cortical O cataract O but O in O this O particular O population O diabetes O is O more O prevalent O in O men B than O women B in O all O age O groups O [ O 29 O ] O . O Differential O exposures O to O cataract O risk O factors O or O different O dietary O or O lifestyle O patterns O between O men B and O women B may O also O be O related O to O these O observations O and O warrant O further O study O . O Conclusion O In O summary O , O in O two O population O - O based O surveys O 6 O years O apart O , O we O have O documented O a O relatively O stable O prevalence O of O cortical O cataract O and O PSC O over O the O period O . O The O observed O overall O increased O nuclear O cataract O prevalence O by O 5 O % O over O a O 6 O - O year O period O needs O confirmation O by O future O studies O , O and O reasons O for O such O an O increase O deserve O further O study O .

O INTRODUCTION O The O quadruplex O structures O formed O by O guanine O - O rich O nucleic O acid O sequences O have O received O significant O attention O recently O because O of O increasing O evidence O for O their O role O in O important O biological O processes O and O as O therapeutic O targets O ( O 1 O - O 5 O ) O . O The O G O - O quadruplex O structure O , O also O known O as O a O G O - O quartet O , O is O formed O by O repeated O folding O of O either O the O single O polynucleotide O molecule O or O by O association O of O two O or O four O molecules O . O The O structure O consists O of O stacked O G O - O tetrads O , O which O are O square O co O - O planar O arrays O of O four O guanine O bases O each O ( O 6 O ) O . O G O - O quadruplex O is O stabilized O with O cyclic O Hoogsteen O hydrogen O bonding O between O the O four O guanines O within O each O tetrad O . O The O present O work O focuses O only O on O the O unimolecular O quadruplexes O , O since O it O is O more O likely O to O be O encountered O in O physiological O conditions O ( O 7 O , O 8 O ) O . O Guanine O - O rich O sequences O capable O of O forming O G O - O quadruplexes O are O found O in O telomeres O , O promoter O regions O , O transcribed O and O other O biologically O important O regions O of O the O mammalian O genomes O . O G O - O quadruplex O DNA O has O been O suggested O to O regulate O DNA O replication O in O retinoblastoma O susceptibility O gene O ( O Rb O ) O region O ( O 9 O ) O . O This O structure O may O control O cellular O proliferation O at O telomeric O level O and O by O transcriptional O regulation O of O oncogenes O like O c O - O myc O ( O 2 O , O 10 O , O 11 O ) O and O c O - O kit O ( O 12 O ) O . O Formation O of O G O - O quadruplex O seems O to O be O regulated O through O interactions O with O cellular O proteins O . O While O some O proteins O help O stabilize O the O structure O ( O 13 O ) O , O others O are O known O to O resolve O it O ( O 1 O , O 4 O , O 14 O , O 15 O ) O . O Proteins O and O chemicals O that O stabilize O the O G O - O quadruplex O structure O can O inhibit O telomerase O action O and O , O therefore O , O are O being O evaluated O as O anticancer O therapeutic O agents O ( O 16 O - O 20 O ) O . O Chemical O compounds O that O inhibit O G O - O quadruplex O helicase O activity O may O also O be O capable O of O regulating O cellular O proliferation O ( O 4 O ) O . O G O - O quadruplexes O are O also O being O eyed O as O potential O antimicrobial O agents O due O to O their O ability O to O transport O monovalent O anions O ( O 21 O ) O . O G O - O quadruplex O motifs O in O the O RNA O have O been O shown O to O play O significant O roles O in O mRNA O turnover O ( O 1 O ) O , O FMRP O binding O ( O 22 O ) O , O translation O initiation O ( O 23 O ) O as O well O as O repression O ( O 24 O ) O . O We O have O shown O previously O that O a O G O - O rich O sequence O ( O GRS O ) O can O mediate O 3 O ' O end O processing O of O mammalian O pre O - O mRNAs O by O interacting O with O DSEF O - O 1 O / O hnRNPH O / O H O ' O protein O ( O 25 O - O 27 O ) O . O Members O of O the O hnRNP O H O protein O family O recognize O G O - O rich O motifs O capable O of O forming O G O - O quadruplexes O and O are O known O to O regulate O polyadenylation O and O splicing O events O in O mammalian O transcripts O ( O 28 O - O 30 O ) O . O Regulated O RNA O processing O is O an O essential O component O of O differential O gene O expression O which O is O central O to O many O important O biologically O processes O . O More O than O half O of O human B genes O are O known O to O have O alternative O polyadenylation O ( O 31 O ) O . O Over O two O - O thirds O of O human B genes O are O thought O to O undergo O alternative O splicing O ( O 32 O ) O . O Sequences O capable O of O forming O G O - O quadruplexes O found O in O the O vicinity O of O polyadenylation O and O splice O sites O act O as O regulators O by O interacting O with O hnRNP O F O and O H O proteins O ( O 25 O - O 27 O , O 30 O , O 33 O ) O . O Whether O quadruplex O structure O directly O plays O a O role O in O regulating O RNA O processing O events O requires O investigation O . O Computational O approaches O to O study O G O - O quadruplexes O in O the O mammalian O genomes O allow O large O - O scale O and O detailed O analysis O of O mammalian O genes O . O Although O , O G O - O quadruplexes O have O been O surveyed O in O the O human B genome O with O such O techniques O ( O 34 O , O 35 O ) O , O there O are O no O known O user O - O friendly O computational O tools O easily O accessible O to O the O public O . O We O had O previously O built O a O database O of O mapped O G O - O quadruplex O sequences O in O selected O alternatively O processed O human B and O mouse B genes O ( O 36 O ) O . O Our O preliminary O analysis O of O the O database O suggests O prevalence O of O such O motifs O near O alternative O splice O and O poly O ( O A O ) O sites O . O We O have O now O developed O a O web O - O based O server O , O QGRS O Mapper O , O that O generates O detailed O information O on O composition O and O distribution O of O putative O quadruplex O forming O G O - O rich O sequences O ( O QGRS O ) O in O any O NCBI O nucleotide O sequence O identified O or O provided O by O the O user O . O The O program O is O also O designed O to O handle O the O analysis O of O mammalian O pre O - O mRNA O sequences O , O including O those O that O are O alternatively O processed O ( O alternatively O spliced O or O alternatively O polyadenylated O ) O . O Researchers O interested O in O predicting O the O ability O of O a O nucleotide O sequence O to O form O G O - O quadruplex O structure O will O find O QGRS O Mapper O to O be O a O user O - O friendly O application O that O provides O many O options O for O analysis O . O The O user O can O define O the O minimum O number O of O tetrads O , O maximum O length O of O the O G O - O quadruplex O motif O , O and O size O as O well O as O composition O of O the O loops O . O The O program O can O map O unimolecular O QGRS O in O the O entire O nucleotide O sequence O provided O in O the O raw O or O FASTA O format O by O the O user O . O This O method O can O be O used O for O the O analysis O of O genomic O sequences O , O e O . O g O . O promoter O and O telomeric O regions O , O as O well O as O RNA O sequences O . O It O is O also O useful O for O predicting O G O - O quadruplex O structures O in O oligonucleotides O . O Alternatively O , O the O program O provides O options O to O search O the O entire O NCBI O Gene O Entrez O , O RefSeq O and O GenBank O databases O in O order O to O retrieve O the O desired O gene O / O nucleotide O sequence O entries O for O analysis O of O their O transcribed O regions O . O Furthermore O , O QGRS O Mapper O is O a O unique O tool O for O mapping O G O - O quadruplex O forming O sequences O in O the O context O of O RNA O processing O sites O . O This O feature O is O very O useful O for O investigating O the O functional O relevance O of O G O - O quadruplex O structure O , O in O particular O its O role O in O regulating O the O gene O expression O by O alternative O processing O . O In O addition O to O providing O data O on O composition O and O locations O of O QGRS O relative O to O the O processing O sites O in O the O pre O - O mRNA O sequence O , O QGRS O Mapper O offers O interactive O graphic O representation O of O the O data O . O The O user O can O also O use O a O graphics O module O to O visualize O QGRS O distribution O patterns O among O all O the O alternative O RNA O products O of O a O gene O simultaneously O on O a O single O screen O . O METHODS O QGRS O definition O The O main O goal O of O the O QGRS O Mapper O program O is O to O predict O the O presence O of O QGRS O in O nucleotide O entries O . O These O putative O G O - O quadruplexes O are O identified O using O the O following O motif O . O GxNy1GxNy2GxNy3Gx O Here O x O = O number O of O guanine O tetrads O in O the O G O - O quadruplex O and O y1 O , O y2 O , O y3 O = O length O of O gaps O ( O i O . O e O . O the O length O of O the O loops O connecting O the O guanine O tetrads O ) O . O The O motif O consists O of O four O equal O length O sets O of O guanines O ( O which O we O call O G O - O groups O ) O , O separated O by O arbitrary O nucleotide O sequences O , O with O the O following O restrictions O . O The O sequence O must O contain O at O least O two O tetrads O ( O i O . O e O . O x O > O = O 2 O ) O . O Although O structures O with O three O or O more O G O - O tetrads O are O considered O to O be O more O stable O , O many O nucleotide O sequences O are O known O to O form O quadruplexes O with O two O G O - O tetrads O ( O 37 O , O 38 O ) O . O QGRS O Mapper O is O meant O to O be O a O flexible O and O comprehensive O tool O for O investigating O G O - O quadruplexes O ; O hence O it O considers O sequences O with O two O tetrads O . O By O default O , O only O QGRS O of O maximum O length O of O 30 O bases O are O considered O . O However O , O the O program O gives O the O user O the O option O to O search O for O sequences O up O to O 45 O bases O . O This O restriction O on O the O length O of O the O sequences O being O considered O is O in O agreement O with O recent O literature O ( O 34 O , O 35 O ) O . O The O maximum O length O of O 30 O bases O restricts O G O - O groups O to O a O maximum O size O of O 6 O . O The O gaps O or O loops O between O the O G O - O groups O may O be O arbitrary O in O composition O or O length O ( O within O the O overall O restrictions O on O the O length O of O QGRS O ) O . O The O program O gives O the O user O the O option O to O search O for O QGRS O having O loops O with O a O specified O length O range O ( O e O . O g O . O the O user O can O search O for O QGRS O with O loops O of O lengths O between O 1 O and O 4 O ) O . O The O user O can O also O specify O a O string O that O one O or O more O loops O of O each O QGRS O must O contain O . O This O string O can O be O given O as O a O regular O expression O . O For O example O , O entering O the O regular O expression O ' O T O { O 3 O , O 5 O } O ' O will O search O for O QGRS O having O one O or O more O loops O that O contain O three O to O five O consecutive O T O ' O s O . O Also O , O at O most O one O of O the O gaps O is O allowed O to O be O of O zero O length O Table O 1 O shows O some O examples O of O valid O QGRS O . O The O guanine O groups O which O form O the O tetrads O are O underlined O . O The O first O sequence O has O four O tetrads O and O equal O length O gaps O . O This O would O seem O to O provide O a O G O - O quadruplex O that O is O the O most O stable O of O the O three O sequences O . O The O second O sequence O is O notable O for O the O significant O differences O in O the O size O of O its O loops O . O The O third O sequence O has O two O tetrads O , O even O though O three O of O the O G O - O groups O could O have O included O another O G O ( O since O all O G O - O groups O must O be O equal O in O size O ) O . O G O - O scores O We O have O devised O a O scoring O system O that O evaluates O a O QGRS O for O its O likelihood O to O form O a O stable O G O - O quadruplex O . O Higher O scoring O sequences O will O make O better O candidates O for O G O - O quadruplexes O . O The O scoring O method O uses O the O following O principles O which O are O based O on O previous O studies O ( O 34 O , O 35 O , O 39 O - O 42 O ) O . O Shorter O loops O are O more O common O than O longer O loops O . O G O - O quadruplexes O tend O to O have O loops O roughly O equal O in O size O . O The O greater O the O number O of O guanine O tetrads O , O the O more O stable O the O quadruplex O . O The O computed O G O - O scores O are O dependent O on O the O user O selected O maximum O QGRS O length O . O The O highest O possible O G O - O score O , O using O the O default O maximum O QGRS O length O of O 30 O , O is O 105 O . O Here O is O a O sequence O attaining O that O score O : O GGGGGGTGGGGGGTGGGGGG O . O Eliminating O QGRS O overlaps O Two O QGRS O are O said O to O overlap O if O their O positions O in O the O nucleotide O sequence O overlap O . O QGRS O Mapper O will O start O with O a O nucleotide O sequence O , O find O all O QGRS O occurring O in O the O sequence O and O then O produce O a O non O - O overlapping O set O of O QGRS O . O Overlaps O are O eliminated O by O selecting O the O higher O scoring O QGRS O . O In O the O non O - O overlapping O view O , O only O this O sequence O will O be O displayed O , O although O the O user O can O request O that O all O overlapping O sequences O be O displayed O . O Please O see O supplementary O materials O at O NAR O online O for O more O details O on O the O elimination O of O overlapping O QGRS O . O FEATURES O Design O and O implementation O QGRS O Mapper O is O a O web O - O based O program O , O written O in O PHP O , O with O Java O being O used O for O some O of O its O graphics O . O The O program O takes O a O nucleotide O sequence O from O NCBI O ( O or O as O provided O by O the O user O ) O and O analyzes O it O for O the O presence O of O putative O G O - O quadruplexes O . O The O structure O of O QGRS O Mapper O is O summarized O in O Table O 2 O . O Search O and O analysis O QGRS O Mapper O allows O the O user O to O search O for O putative O G O - O quadruplexes O in O a O variety O of O ways O . O It O is O possible O to O enter O a O nucleotide O sequence O in O raw O or O FASTA O format O for O analysis O . O One O can O search O and O analyze O gene O sequences O by O Gene O ID O , O Gene O name O or O symbol O , O accession O number O or O GI O number O for O an O NCBI O nucleotide O sequence O entry O . O The O user O can O opt O to O change O the O maximum O length O of O QGRS O that O will O be O searched O for O ( O the O default O maximum O length O being O 30 O ) O and O change O the O minimum O sized O G O - O group O ( O which O is O two O by O default O ) O . O Also O , O the O user O can O specify O that O the O loops O in O the O QGRS O fall O within O a O given O size O range O and O that O one O or O more O loops O of O the O QGRS O contain O a O given O string O ( O for O which O the O user O may O enter O a O regular O expression O ) O . O The O web O page O for O QGRS O analysis O can O be O seen O in O Figure O 1 O . O After O entering O a O sequence O in O raw O or O FASTA O format O , O QGRS O Mapper O will O search O the O sequence O for O occurrences O of O QGRS O . O The O user O may O enter O any O combination O of O the O letters O A O , O C O , O T O , O G O , O U O , O N O . O The O Gene O ID O field O allows O the O user O to O search O the O NCBI O Entrez O Gene O database O . O QGRS O Mapper O will O connect O to O NCBI O , O download O and O parse O the O gene O entry O , O and O then O analyze O the O transcribed O region O of O its O nucleotide O sequence O for O the O presence O of O QGRS O . O For O example O , O entering O the O gene O ID O 403437 O results O in O downloading O the O Brca1 O gene O sequence O for O Canis B familiaris I . O Using O the O default O QGRS O search O parameters O , O QGRS O Mapper O finds O 156 O non O - O overlapping O QGRS O and O 3394 O overlapping O QGRS O in O the O transcribed O region O of O this O gene O . O The O Gene O Name O or O Gene O Symbol O field O also O allows O the O user O to O search O the O NCBI O databases O for O all O such O genes O . O Entering O the O gene O name O Bcl2 O results O in O nine O different O hits O which O are O displayed O in O Table O 3 O . O All O nine O of O these O entries O can O be O analyzed O for O the O occurrence O of O QGRS O . O Clicking O on O the O Gene O ID O takes O the O user O to O the O respective O Entrez O Gene O entry O . O Clicking O on O the O last O column O initiates O analysis O of O the O selection O by O QGRS O Mapper O . O Similarly O , O the O user O can O also O enter O an O NCBI O accession O number O to O search O for O gene O sequences O . O For O example O , O searching O the O accession O number O AF312033 O results O in O 12 O hits O being O displayed O for O this O GenBank O nucleotide O sequence O entry O . O The O search O phase O of O the O program O is O followed O by O an O analysis O of O the O QGRS O contained O in O the O query O sequence O . O In O this O phase O of O QGRS O Mapper O , O the O sequence O data O downloaded O previously O is O analyzed O to O identify O and O map O all O QGRS O relative O to O locations O such O as O splice O sites O in O exons O / O introns O , O and O poly O ( O A O ) O site O ( O if O these O locations O are O known O ) O . O Furthermore O the O QGRS O are O scored O by O the O method O described O above O . O The O computed O G O - O score O is O used O to O eliminate O overlapping O QGRS O . O At O times O , O QGRS O Mapper O must O analyze O a O considerable O amount O of O data O . O For O example O , O the O mouse B version O of O the O gene O PTPRU O , O which O is O 69822 O bases O long O , O contains O 94681 O QGRS O of O length O up O to O 45 O bases O . O QGRS O Mapper O will O find O , O analyze O and O map O all O of O these O sequences O . O During O this O analysis O a O message O is O displayed O indicating O the O estimated O time O left O to O completion O . O QGRS O Mapper O output O After O the O analysis O of O overlaps O is O completed O , O QGRS O Mapper O displays O a O summary O of O its O findings O , O in O the O Gene O View O . O This O summary O includes O basic O gene O information O such O as O the O gene O ID O , O gene O symbol O , O gene O name O , O a O link O to O the O NCBI O entry O , O organism O name O , O chromosome O number O and O number O of O products O and O poly O ( O A O ) O signals O . O Information O is O also O given O for O each O product O , O such O as O the O number O of O exons O and O introns O , O number O of O QGRS O ( O non O - O overlapping O and O overlapping O ) O , O number O of O QGRS O found O near O RNA O processing O sites O , O and O a O visual O map O of O the O product O . O As O an O example O , O the O Gene O View O for O the O human B GREB1 O is O displayed O in O Figure O 2 O , O showing O the O table O of O gene O information O and O product O information O for O the O first O product O ( O the O output O for O all O products O may O be O seen O in O the O supplementary O material O ) O . O At O this O stage O in O the O analysis O the O user O can O choose O among O three O further O displays O : O ' O Data O View O ' O , O ' O Data O View O ( O with O overlaps O ) O ' O and O ' O Graphics O View O ' O . O This O can O be O done O for O the O entire O gene O or O for O any O particular O product O . O In O the O Data O View O , O a O table O is O displayed O showing O information O for O each O of O the O set O of O non O - O overlapping O QGRS O . O This O table O displays O the O position O of O the O QGRS O , O which O exon O / O intron O it O appears O in O , O its O distance O from O 3 O ' O and O 5 O ' O splice O sites O , O the O QGRS O sequence O ( O with O each O G O - O group O underlined O ) O and O the O corresponding O G O - O score O . O Similar O display O is O also O shown O for O each O QGRS O mapped O to O poly O ( O A O ) O region O in O the O product O . O If O the O user O requests O the O Data O View O for O the O entire O gene O , O then O the O QGRS O information O is O shown O for O each O product O . O The O ' O Data O View O ( O with O overlaps O ) O ' O gives O the O same O information O but O shows O the O locations O of O all O QGRS O . O Figure O 3 O shows O the O Data O View O for O product O 1 O of O the O GREB1 O gene O . O The O user O can O also O choose O the O Graphics O View O to O give O a O visual O display O of O the O location O of O QGRS O . O This O allows O the O user O to O see O the O location O of O QGRS O relative O to O exons O and O introns O ( O if O that O information O is O available O ) O . O The O Graphics O View O has O the O following O components O . O A O graphic O display O of O the O entire O gene O ( O showing O the O location O of O the O exons O ) O . O This O display O includes O a O sliding O window O that O can O be O used O to O focus O on O any O particular O segment O of O the O gene O .

O A O Canadian O review O on O drug O therapy O guidelines O found O significant O variation O in O quality O depending O on O the O developer O [ O 13 O ] O . O Approximately O 25 O % O of O guidelines O were O not O recommended O for O use O in O practice O by O the O appraisers O ' O criteria O [ O 13 O ] O . O As O an O example O of O the O volume O of O clinical O practice O guidelines O available O , O eleven O recent O guidelines O on O community O acquired O pneumonia O exist O [ O 15 O ] O . O To O add O to O the O complexities O involved O with O keeping O current O with O pharmacotherapeutic O management O strategies O , O as O of O 2000 O , O there O were O over O 22 O , O 000 O drug O products O approved O for O sale O in O Canada O for O human B use O [ O 16 O ] O . O There O is O also O considerable O debate O regarding O what O constitutes O " O evidence O " O in O practice O , O which O contributes O to O confusion O for O clinicians O [ O 17 O , O 18 O ] O . O Sim O et O al O . O succinctly O describe O the O gap O between O evidence O and O action O as O difficulties O with O obtaining O , O systematically O reviewing O , O applying O in O context O , O and O measuring O the O outcome O following O application O of O evidence O [ O 19 O ] O . O Maintaining O competence O - O nurse O practitioners O as O a O new O group O of O prescribers O Competencies O for O nurse O practitioners O ( O NPs O ) O on O a O local O and O international O level O include O critically O appraising O and O applying O literature O and O research O findings O in O practice O [ O 20 O - O 23 O ] O . O The O Canadian O Nurses O Association O ( O CNA O ) O has O developed O the O Canadian O Nurse O Practitioner O Core O Competency O Framework O that O describes O the O knowledge O , O skills O , O judgment O , O and O attributes O required O for O practice O . O Evidence O based O practice O is O integral O to O pharmacotherapeutic O interventions O and O prescribing O competencies O [ O 23 O ] O . O The O National O Prescribing O Centre O , O an O organization O of O the O National O Health O Service O in O the O UK O , O describes O several O competencies O around O information O needs O relevant O to O prescribing O and O emphasis O is O placed O on O using O relevant O and O up O to O date O information O in O various O formats O ( O e O . O g O . O print O , O electronic O , O verbal O ) O . O Several O related O competencies O include O understanding O advantages O and O disadvantages O of O information O sources O and O the O currency O of O resources O [ O 21 O ] O . O Researchers O in O the O US O developed O NP O informatics O competencies O for O integration O into O advanced O nursing O practice O curricula O [ O 24 O ] O . O Competencies O related O to O informatics O knowledge O include O critical O analysis O of O data O and O information O for O use O in O evidence O based O practice O , O evaluating O and O applying O relevant O information O , O synthesizing O best O evidence O , O and O using O optimal O search O strategies O to O locate O clinically O sound O and O useful O studies O from O information O resources O [ O 24 O ] O . O Achieving O and O maintaining O competence O in O these O domains O as O well O as O a O solid O foundation O in O pharmacology O is O necessary O to O support O NPs O in O their O relatively O new O role O as O a O prescriber O [ O 25 O - O 27 O ] O . O Knowledge O management O and O information O seeking O behaviours O among O nurse O practitioners O and O physicians O Information O seeking O behaviours O of O physicians O are O better O documented O than O NPs O [ O 11 O ] O . O Information O related O to O diagnosis O is O important O to O both O groups O but O drug O therapy O queries O may O occur O more O frequently O with O NPs O [ O 28 O - O 33 O ] O . O Research O on O nurses O ' O behaviours O related O to O information O seeking O is O available O from O the O hospital O setting O [ O 33 O - O 35 O ] O but O the O generalizability O of O these O behaviours O to O NPs O with O a O prescribing O role O is O unclear O . O Differences O in O nursing O roles O , O responsibilities O , O and O legislation O , O including O prescriptive O authority O , O exist O depending O on O the O country O of O practice O . O Nurse O practitioners O and O their O collaborating O physician O partners O in O Nova O Scotia O Nova O Scotia O is O a O Canadian O province O with O a O population O of O approximately O 942 O , O 000 O [ O 36 O ] O . O The O province O is O divided O into O six O health O zones O that O include O nine O district O health O authorities O , O one O of O which O includes O the O provincial O capital O and O is O considered O to O be O urban O [ O 37 O , O 38 O ] O . O Health O care O service O delivery O is O challenging O due O to O many O factors O including O the O rural O nature O of O the O province O , O which O is O estimated O to O be O 60 O % O of O population O [ O 37 O , O 39 O ] O . O Starting O in O 1998 O , O the O Nova O Scotia O Department O of O Health O led O an O initiative O to O explore O different O methods O of O delivering O , O managing O , O and O funding O primary O care O services O . O The O Strengthening O Primary O Care O in O Nova O Scotia O Communities O Initiative O ( O SPCI O ) O was O established O with O the O selection O of O four O primary O care O demonstration O sites O where O a O primary O health O care O NP O was O hired O to O practice O collaboratively O with O one O or O more O family O / O general O physicians O and O other O members O of O an O interdisciplinary O team O . O Each O demonstration O site O adopted O alternative O ( O non O fee O - O for O - O service O ) O physician O payment O mechanisms O and O used O electronic O patient B records O ( O EPRs O ) O to O support O service O delivery O [ O 41 O ] O . O Demonstration O sites O participated O in O project O evaluation O components O that O included O , O but O were O not O limited O to O , O NP O roles O , O alternative O fee O structures O , O consumer O satisfaction O , O and O implementation O and O integration O of O EPRs O [ O 41 O , O 42 O ] O . O Legislation O to O allow O NPs O to O practice O collaboratively O with O physicians O in O Nova O Scotia O was O passed O in O 2002 O , O part O way O through O the O SPCI O project O [ O 39 O ] O . O Prescriptive O authority O granted O through O legislation O authorizes O NPs O to O prescribe O from O a O schedule O of O drugs O [ O 43 O , O 44 O ] O . O At O the O time O of O conducting O this O research O project O , O 16 O primary O health O care O NPs O were O in O active O practice O [ O 43 O ] O . O The O EPR O component O of O the O SPCI O project O evaluation O provided O information O on O the O use O of O technologies O in O the O community O context O . O Results O from O the O implementation O process O indicated O that O considerable O attention O is O required O for O technology O literacy O , O time O for O training O , O and O selection O of O software O for O EPRs O [ O 41 O ] O . O Although O the O majority O of O community O - O based O , O non O - O institutional O clinical O practice O settings O in O Nova O Scotia O primarily O operate O with O paper O - O based O charting O systems O , O there O is O a O movement O toward O integrating O electronic O technologies O , O including O the O EPR O , O in O practice O among O health O care O providers O , O administrators O , O and O the O provincial O government O . O In O addition O to O recording O patient B visit O information O , O a O component O of O the O EPR O package O serves O to O provide O drug O information O resources O . O Drug O therapy O information O resources O for O NPs O and O nurse O prescribers O have O frequently O been O described O as O essential O in O supporting O practice O [ O 25 O , O 28 O , O 29 O ] O . O The O role O of O NPs O is O relatively O new O in O Canada O [ O 39 O ] O and O there O is O limited O information O available O to O indicate O the O type O of O resources O ( O e O . O g O . O print O , O electronic O , O EPR O based O ) O these O prescribers O use O for O drug O and O therapeutic O information O queries O at O the O point O of O care O . O It O is O unknown O as O to O whether O differences O exist O regarding O types O of O resources O used O , O drug O information O needs O , O and O utilization O patterns O among O NPs O and O collaborating O physician O partners O . O Some O research O has O suggested O that O the O degree O of O multidisciplinary O team O functioning O relates O to O the O adoption O of O technology O or O innovations O in O practice O but O more O research O is O required O to O determine O the O extent O of O these O relationships O [ O 45 O , O 46 O ] O . O The O use O of O EPR O technology O is O increasing O in O Nova O Scotia O but O little O information O is O available O regarding O the O readiness O of O practitioners O for O use O of O specific O features O such O as O drug O information O resources O . O Based O on O the O EPR O related O results O of O the O SPCI O evaluation O , O use O of O these O functions O could O be O challenging O without O proper O facilitation O . O The O purpose O of O the O survey O for O this O research O was O to O describe O drug O information O resources O used O by O NPs O and O their O collaborating O physician O partners O at O the O point O of O care O . O The O results O of O the O survey O will O be O used O to O guide O further O technology O implementation O strategies O and O stimulate O further O discussion O around O drug O information O resource O usage O at O the O point O of O care O . O Methods O Survey O development O Survey O development O involved O three O stages O including O identification O of O important O content O areas O , O development O of O draft O questions O , O and O survey O refinement O . O Identifying O important O content O areas O for O inclusion O in O the O survey O involved O conducting O a O comprehensive O English O language O literature O search O , O consultation O with O relevant O stakeholders O ( O e O . O g O . O members O of O the O Nova O Scotia O Department O of O Health O ) O , O and O input O from O subject O matter O experts O at O Dalhousie O University O . O The O literature O review O was O conducted O using O the O following O bibliographic O databases O : O PubMed O , O Cumulative O Index O to O Nursing O and O Allied O Health O Literature O ( O CINAHL O ) O , O International O Pharmaceutical O Abstracts O ( O IPA O ) O , O and O Web O of O Science O Citation O Databases O . O Hand O and O electronic O searching O of O relevant O journals O was O also O conducted O . O Broad O search O terms O were O used O without O limits O on O publication O date O or O place O as O nurse O practitioner O titles O , O roles O and O scopes O of O practice O , O and O terminology O regarding O technology O vary O nationally O and O internationally O . O Some O examples O of O terms O used O included O nurse O practitioner O , O nurse O prescriber O , O nurse O clinicians O , O district O nurse O , O health O visitor O , O drug O information O resources O , O drug O information O services O , O information O needs O , O and O information O technology O . O The O draft O survey O was O reviewed O by O the O research O team O to O reduce O the O number O of O items O and O improve O clarity O . O The O layout O of O the O questionnaire O was O carefully O examined O to O ensure O that O it O was O easy O to O follow O and O complete O . O Research O results O from O a O previous O investigation O of O Nova O Scotian O physicians O ' O behaviours O regarding O drug O information O were O also O used O to O further O revise O the O survey O [ O 47 O ] O . O This O draft O questionnaire O was O pilot O tested O by O two O out O of O province O NPs O and O one O physician O . O The O results O of O the O pilot O were O used O to O make O final O revisions O to O the O survey O . O Based O on O pilot O - O testing O feedback O and O investigator O consensus O , O the O final O survey O was O divided O into O 2 O versions O , O one O for O personal O digital O assistant O ( O PDA O ) O users O and O one O for O computer O users O . O The O 10 O page O surveys O for O PDA O and O computer O users O had O 5 O or O 6 O sections O , O respectively O , O and O 37 O questions O , O many O with O multiple O parts O . O The O survey O content O included O demographics O , O computer O or O PDA O use O and O experience O , O drug O and O therapeutic O resource O use O and O preferences O , O PDA O future O use O , O perceived O barriers O and O facilitators O to O PDA O use O , O and O technology O training O preferences O . O Section O one O contained O demographic O questions O such O as O gender O , O age O , O job O title O , O volume O of O patients B , O and O EPR O availability O in O the O practice O setting O . O Section O two O was O designed O to O determine O PDA O or O computer O use O and O experience O in O the O practice O setting O with O questions O regarding O length O of O use O , O costs O , O and O work O versus O home O usage O . O This O section O also O addressed O usage O and O rating O of O different O drug O information O resources O . O Resource O ratings O were O based O on O the O frequency O of O usage O , O usefulness O , O accessibility O , O credibility O , O and O current O / O timeliness O . O Resources O were O grouped O as O print O ( O i O . O e O . O books O , O journals O , O and O clinical O practice O guidelines O ) O , O online O / O electronic O resources O , O and O health O professionals O and O other O . O Respondents O used O 5 O - O point O Likert O scales O ( O strongly O agree O to O strongly O disagree O ) O for O rating O opinions O related O to O resources O . O A O rating O of O 6 O ( O not O applicable O , O I O do O not O use O this O resource O ) O was O also O included O for O respondents O who O did O not O use O a O particular O resource O . O Frequency O of O searching O for O specific O information O was O rated O on O a O 3 O - O point O Likert O scale O ( O frequently O to O never O ) O . O The O final O sections O of O the O survey O included O categorical O , O open O - O ended O , O and O Likert O scale O questions O regarding O preferred O resources O , O technology O barriers O , O PDA O future O use O , O and O technology O training O preferences O . O Copies O of O the O surveys O are O attached O as O an O appendix O in O PDF O format O [ O see O additional O file O 1 O and O 2 O ] O or O can O also O be O accessed O from O the O Initiative O for O Medication O Management O , O Policy O Analysis O , O Research O & O Training O ( O IMPART O ) O website O [ O 48 O ] O . O Ethics O approval O for O the O survey O was O granted O through O Dalhousie O University O Research O Ethics O Board O on O February O 3 O , O 2005 O . O Survey O population O Licensed O , O actively O practicing O , O primary O health O care O NPs O ( O n O = O 16 O ) O and O their O collaborating O physician O partners O ( O n O = O 21 O ) O were O eligible O to O participate O . O Survey O procedures O The O survey O recruitment O procedures O were O based O on O the O methods O of O Dillman O [ O 49 O ] O and O Salant O and O Dillman O [ O 50 O ] O . O Survey O packages O contained O a O cover O letter O , O separate O surveys O for O PDA O and O computer O users O , O and O a O return O self O - O addressed O stamped O envelope O . O The O covering O letter O instructed O respondents O to O self O - O select O the O appropriate O survey O ( O either O PDA O or O computer O ) O based O on O their O drug O information O seeking O behaviours O . O Participants B who O had O used O a O PDA O at O any O time O were O instructed O to O complete O the O PDA O version O of O the O survey O . O Those O who O had O never O used O a O PDA O for O drug O information O were O instructed O to O complete O the O computer O version O of O the O survey O . O Several O strategies O were O used O to O optimize O response O rate O and O included O : O personalized O cover O letters O , O coloured O paper O for O surveys O , O stamped O return O envelopes O , O follow O - O up O mailing O , O and O a O priority O post O mailing O [ O 51 O ] O . O The O covering O letter O included O coloured O logos O of O Dalhousie O University O and O the O Nova O Scotia O Department O of O Health O representing O the O investigator O affiliations O and O endorsement O of O the O project O . O A O master O mailing O list O with O names O and O addresses O of O NPs O and O their O collaborating O physician O partners O was O created O . O To O maintain O confidentiality O of O respondents O , O a O number O placed O on O the O bottom O right O corner O of O each O survey O corresponded O to O a O name O on O the O confidential O master O mailing O sheet O .

O The O clinicians O in O our O sample O perceived O the O Canadian O compendium O , O the O CPS O , O to O be O useful O , O accessible O , O credible O , O and O current O / O timely O . O The O CPS O , O is O described O as O " O the O Canadian O drug O reference O for O health O professionals O " O and O is O intended O to O provide O a O central O source O of O drug O information O on O drug O products O available O in O Canada O [ O 52 O ] O . O It O is O available O in O print O ( O English O and O French O ) O and O became O available O online O in O June O 2004 O . O The O CPS O includes O drug O monographs O for O commonly O used O products O approved O for O use O in O Canada O , O but O it O does O not O include O all O drugs O available O on O the O Canadian O market O [ O 57 O ] O . O The O majority O of O these O product O monographs O are O based O on O monographs O submitted O by O pharmaceutical O manufacturers O and O approved O by O Health O Canada O . O Some O of O the O monographs O are O written O by O the O Canadian O Pharmacists O Association O and O are O described O as O being O evidence O - O based O [ O 52 O ] O . O The O CPS O also O includes O more O than O 100 O pages O of O clinical O tools O [ O 52 O ] O .

O The O accuracy O of O particular O components O of O CPS O monographs O has O also O been O investigated O . O A O review O of O overdose O management O in O 119 O monographs O from O the O 2001 O CPS O revealed O considerable O variability O in O the O utility O of O information O with O 50 O % O of O the O monographs O containing O misleading O or O dangerous O advice O [ O 59 O ] O .

O Some O authors O have O criticized O references O that O are O similar O to O the O CPS O as O being O inadequate O with O regard O to O inclusion O of O evidence O based O information O [ O 60 O ] O . O The O NPs O in O our O sample O also O rated O Therapeutic O Choices O highly O for O all O characteristics O . O This O finding O is O most O likely O attributable O to O the O fact O that O it O is O a O recommended O resource O for O coursework O associated O with O the O Dalhousie O NP O university O program O curriculum O .

O Health O professionals O Reliance O on O other O health O professionals O , O especially O pharmacists O and O physicians O , O as O a O resource O for O information O was O evident O from O our O study O and O concurs O with O the O findings O of O others O [ O 28 O , O 32 O , O 55 O , O 61 O ] O . O Nurse O practitioners O have O reported O that O collaborative O relationships O with O pharmacists O increase O NP O role O satisfaction O [ O 61 O ] O .

O Some O qualitative O feedback O does O however O support O this O notion O . O As O an O example O , O in O response O to O a O request O for O a O rationale O for O not O using O computers O one O physician O commented O : O " O Retro O tech O [ O sic O ] O / O old O fashion O .

O Barriers O that O were O identified O with O our O sample O regarding O the O use O of O handheld O technologies O such O as O PDAs O included O cost O , O time O , O and O issues O related O to O technology O literacy O . O Several O people B questioned O the O value O of O PDAs O . O One O GP O stated O when O referring O to O a O PDA O : O " O So O far O I O have O not O discovered O a O use O for O one O " O . O Other O respondents O reinforced O their O preferences O for O other O resources O ( O e O . O g O . O books O ) O and O resistance O to O technology O . O When O responding O to O barriers O for O the O use O of O PDAs O , O one O NP O commented O , O " O My O huge O dislike O for O machinery O that O frequently O requires O updating O and O patience O " O .

O Facilitators O to O the O use O of O PDAs O mainly O included O convenience O factors O such O as O having O resources O all O in O one O place O , O faster O means O to O get O information O , O and O portability O . O Our O sample O was O not O in O agreement O with O some O convenience O factors O in O that O they O did O not O feel O that O PDAs O would O decrease O paperwork O . O Practitioners O from O our O sample O felt O relatively O neutral O about O PDAs O improving O patient B ' O s O health O outcomes O with O 41 O % O responding O in O this O manner O . O Results O from O a O sample O of O primary O care O practitioners O in O the O US O revealed O that O 76 O % O agreed O that O the O use O of O handheld O devices O for O electronic O prescribing O would O substantially O reduce O medical O errors O and O improve O the O quality O of O health O care O [ O 67 O ] O . O Our O study O also O suggests O that O resources O such O as O the O Cochrane O Library O and O its O Database O of O Systematic O Reviews O were O not O frequently O used O . O This O finding O is O similar O to O that O of O other O investigators O [ O 30 O , O 35 O , O 64 O ] O . O Despite O the O desire O of O some O clinicians O to O use O these O resources O , O lack O of O confidence O and O ability O to O use O them O appropriately O has O been O found O [ O 30 O , O 64 O , O 68 O , O 69 O ] O . O Our O study O suggests O that O although O this O resource O is O perceived O as O credible O , O current O / O timely O , O and O useful O , O it O is O also O perceived O to O be O somewhat O inaccessible O . O The O Cochrane O Library O is O available O to O the O health O professionals O ( O e O . O g O .

O This O is O exemplified O by O one O respondent O ' O s O statement O " O knowledge O regarding O good O software O programs O " O as O a O barrier O to O the O use O of O PDAs O . O Pharmaceutical O industry O The O influence O of O the O pharmaceutical O industry O on O physician O prescribing O and O research O outcomes O has O been O documented O [ O 81 O , O 82 O ] O . O Although O NP O use O of O industry O representatives O as O a O source O of O pharmacological O information O has O been O documented O , O the O influence O on O prescribing O is O largely O uninvestigated O [ O 32 O , O 61 O , O 83 O - O 85 O ] O . O The O CNA O competency O framework O includes O a O statement O regarding O prescribing O and O industry O relations O [ O 23 O ] O . O In O our O study O , O the O physician O and O NP O rankings O of O industry O representatives O were O similar O .

O Following O academic O detailing O , O physician O and O NP O rankings O of O pharmaceutical O industry O representatives O were O second O or O third O for O frequency O of O use O , O usefulness O , O accessibility O , O credibility O , O and O current O / O timeliness O . O Limitations O We O do O not O have O demographics O or O information O regarding O the O reasons O why O survey O recipients O did O not O respond O . O As O per O ethical O requirements O to O maintain O confidentiality O of O respondents O , O we O were O not O able O to O match O respondents O from O their O respective O place O of O practice O and O therefore O cannot O conclude O whether O the O practitioners O within O a O practice O setting O influenced O the O others O ' O responses O . O The O sample O size O of O the O survey O is O small O although O it O includes O 88 O % O response O from O community O based O NPs O in O Nova O Scotia O . O The O generalizability O of O the O results O is O limited O due O to O the O variations O in O NP O scopes O of O practice O nationally O and O internationally O . O It O is O unknown O whether O the O findings O are O generalizable O to O nonresponding O physicians O within O Nova O Scotia O collaborating O with O NPs O or O to O physicians O not O in O collaborative O practices O with O NPs O as O they O were O not O included O as O a O part O of O the O sample O . O Due O to O multiple O statistical O comparisons O ( O Mann O Whitney O U O ) O , O the O results O comparing O NP O and O physician O ratings O of O results O should O be O interpreted O with O caution O . O Conclusion O Respondent O ratings O of O resources O and O preferences O for O resource O use O were O consistent O with O self O - O reported O means O of O conducting O searches O for O specific O drug O information O queries O .

O INTRODUCTION O The O p53 O tumor O suppressor O gene O remains O the O most O frequently O altered O gene O in O human B tumors O . O Several O p53 O mutation O databases O have O been O reported O previously O ( O 1 O - O 3 O ) O , O and O to O date O , O more O than O 1500 O different O p53 O mutants O have O been O described O ( O 4 O ) O . O Functional O inactivation O of O p53 O is O usually O due O to O gene O mutation O , O deletion O or O protein O degradation O . O In O general O , O the O majority O of O p53 O mutations O in O human B neoplasia O are O missense O mutations O affecting O the O DNA O - O binding O domain O ( O DBD O ) O . O Unlike O other O human B cancers O , O p53 O in O neuroblastoma O ( O NB O ) O is O rarely O mutated O in O the O primary O tumor O at O diagnosis O but O high O levels O of O wild O - O type O p53 O ( O wt O p53 O ) O protein O expression O have O been O found O in O the O cytoplasm O of O undifferentiated O tumors O ( O 5 O , O 6 O ) O . O More O recently O , O in O normal O unstressed O cells O , O wt O p53 O protein O was O found O to O be O retained O in O the O cytoplasm O as O a O latent O form O , O in O huge O , O p53 O - O associated O protein O complexes O known O as O ' O Parc O ' O ( O 7 O ) O . O The O steady O - O state O concentration O of O p53 O in O normal O unstressed O cells O is O usually O very O low O because O of O the O short O half O - O life O of O the O wild O - O type O ( O wt O ) O protein O . O Overexpression O of O p53 O in O most O of O the O transformed O cells O containing O a O missense O mutation O within O the O p53 O gene O appears O to O be O due O to O the O increased O stability O of O mutated O p53 O ( O 8 O ) O . O In O unstressed O NB O cells O , O high O wt O p53 O expression O may O reflect O the O embryonic O origin O of O NBs O , O in O which O precursor O cells O fail O to O mature O ( O 9 O ) O . O p53 O mutations O are O unusual O in O human B NB O but O , O when O they O do O occur O , O are O found O in O post O - O chemotherapy O tumors O . O In O this O respect O , O Tweddle O et O al O . O ( O 10 O ) O described O how O two O NB O cell O lines O derived O from O the O same O patient B can O elicit O a O different O p53 O status O : O wt O p53 O for O SK O - O N O - O BE O ( O 1a O ) O established O before O treatment O , O and O mutated O p53 O for O SK O - O N O - O BE O ( O 2c O ) O established O after O relapse O of O the O patient B under O treatment O with O cytotoxic O agents O such O as O cyclophosphamide O , O doxorubicin O , O vincristine O and O radiotherapy O . O In O NB O cell O lines O , O p53 O mutation O has O been O found O in O multidrug O - O resistant O cells O ( O 11 O ) O .

O This O led O us O to O hypothesize O that O the O shorter O protein O expressed O by O the O SK O - O N O - O AS O cell O line O could O be O the O p53 O beta O isoform O .

O None O of O the O mutant O cells O , O regardless O of O the O type O of O mutation O , O was O able O to O induce O p21 O / O WAF1 O protein O accumulation O , O unlike O the O 3 O p53 O wild O - O type O cells O ( O SH O - O SY5Y O , O IMR O - O 32 O and O LAN O - O 5 O ) O . O Genomic O status O of O TP53 O region O in O the O various O cell O lines O According O to O Knudson O ' O s O ' O two O hit O ' O model O of O tumor O suppressor O gene O functional O inactivation O , O the O mutation O of O one O allele O is O supposed O to O be O associated O with O a O deletion O of O the O second O allele O . O To O assess O this O genetic O mechanism O , O we O performed O FISH O experiments O to O search O for O deletions O of O one O copy O of O the O TP53 O region O , O especially O in O cell O lines O with O a O mutated O TP53 O gene O . O For O this O purpose O , O metaphase O preparations O of O the O studied O cell O lines O were O cohybridized O with O a O p53 O DNA O probe O labeled O in O red O ( O BAC O clone O RP11 O - O 199F11 O ) O as O described O previously O ( O 25 O ) O and O a O chromosome O 17 O - O specific O centromeric O probe O labeled O in O green O . O The O three O cell O lines O shown O previously O to O express O a O wt O p53 O protein O ( O LAN5 O , O IMR32 O and O SH O - O SY5Y O ) O , O displayed O as O expected O two O signals O with O each O probe O , O confirming O the O presence O of O both O TP53 O alleles O in O these O cells O ( O Figure O 8 O and O Table O 3 O ) O . O Conversely O , O IGR O - O N O - O 91 O and O SK O - O N O - O AS O cell O lines O displayed O only O one O fluorescent O signal O for O each O probe O , O suggesting O a O whole O chromosome O 17 O lost O , O or O at O least O losses O of O the O 17p O arm O and O the O centromeric O region O . O The O SK O - O N O - O BE O ( O 2 O ) O cell O line O has O been O described O as O containing O only O one O chromosome O 17 O and O one O TP53 O signal O ( O 10 O ) O . O In O our O analysis O , O only O 10 O % O of O the O cells O displayed O this O characteristic O , O whilst O most O of O the O cells O had O two O copies O of O both O ( O Figure O 8 O and O Table O 3 O ) O . O p53 O sequencing O , O however O , O confirmed O the O previously O described O mutation O , O and O the O absence O of O a O normal O allele O , O suggesting O that O the O cells O used O in O our O study O had O acquired O , O during O culture O , O an O uniparental O disomy O for O the O TP53 O - O mutated O chromosome O 17 O . O Finally O , O the O other O two O cell O lines O ( O LAN O - O 1 O and O IGR O - O NB8 O ) O displayed O highly O variable O genetic O heterogeneity O from O one O cell O to O the O next O ( O Table O 3 O ) O . O Surprisingly O , O although O p53 O transcripts O are O extremely O faintly O expressed O in O LAN O - O 1 O cell O line O , O all O cells O showed O several O FISH O signals O with O the O 167 O kb O BAC O probe O used O here O . O To O understand O this O apparent O contradiction O , O an O array O - O CGH O experiment O was O performed O on O an O oligo O - O array O Agilent O , O which O indicated O a O 133 O kb O interstitial O deletion O corresponding O to O the O p53 O coding O region O and O the O 97 O kb O upstream O region O . O Accordingly O , O the O fluorescent O spots O observed O in O FISH O experiments O on O LAN O - O 1 O cells O should O be O related O to O the O hybridization O of O the O 57 O kb O region O downstream O of O p53 O gene O present O in O the O BAC O probe O . O IGRN O - O B8 O cell O line O displayed O a O number O of O signals O of O both O colors O ranging O from O 0 O to O 4 O , O with O 87 O % O of O cells O displaying O a O loss O for O one O TP53 O allele O . O Despite O this O genomic O variability O , O analysis O of O the O p53 O protein O showed O a O single O shortened O form O in O IGR O - O N O - O B8 O cell O line O ( O Figure O 1 O ) O .

O DISCUSSION O The O p53 O gene O , O the O ' O genome O guardian O ' O , O is O mutated O in O over O 50 O % O of O human B cancers O , O with O the O most O common O mutations O being O missense O mutations O ( O > O 2 O / O 3 O of O mutations O ) O ( O 26 O ) O . O In O human B neuroblastoma O tumors O , O p53 O mutations O are O rarely O present O at O the O time O of O diagnosis O ( O 5 O , O 27 O ) O ; O however O , O oncogenic O p53 O mutations O can O be O found O in O advanced O neuroblastomas O that O often O relapse O following O high O - O dose O chemotherapy O ( O 10 O ) O . O In O contrast O , O in O breast O cancers O , O it O has O been O reported O that O p53 O mutations O might O improve O response O to O high O - O dose O chemotherapy O including O therapy O with O epirubicin O and O cyclophosphamide O ( O 28 O ) O . O An O investigation O into O the O p53 O genomic O status O and O functions O of O eight O human B NB O lines O revealed O that O all O five O of O the O mutated O cell O lines O had O distinct O genetic O characteristics O as O is O schematically O represented O in O Figure O 9 O : O SK O - O N O - O BE O ( O 2 O ) O with O a O single O missense O mutation O in O the O p53 O gene O , O encoding O a O highly O stable O full O - O length O protein O . O SK O - O N O - O AS O and O IGR O - O NB8 O proteins O , O although O they O have O intact O transactivation O and O DBDs O , O were O truncated O at O the O C O - O terminus O generating O 341 O and O 326 O amino O acids O respectively O ; O they O therefore O lack O the O tetramerization O domain O that O is O essential O for O an O active O conformation O . O Very O recently O , O Bourdon O et O al O . O ( O 22 O ) O reported O the O putative O occurrence O of O beta O and O gamma O isoforms O from O different O tissues O due O to O alternate O splicing O that O indicates O the O similarity O to O those O of O p73 O and O p63 O as O identified O previously O by O Daniel O Caput O and O co O - O workers O ( O 29 O ) O . O In O the O p53 O isoforms O scheme O proposed O by O Bourdon O et O al O . O ( O 22 O ) O , O the O SK O - O N O - O AS O cell O line O that O elicits O p53i9 O protein O expression O is O consistent O with O the O p53 O beta O isoform O . O Genomic O analysis O reveals O that O the O only O occurrence O of O the O p53 O beta O isoform O in O SK O - O N O - O AS O results O from O a O deletion O spanning O the O intron O 9 O / O exon O 10 O junction O . O Similar O to O the O p53 O beta O isoform O in O SK O - O N O - O AS O , O the O p53 O in O IGR O - O NB8 O that O lacks O 67 O amino O acids O at O C O - O terminus O was O , O alone O , O unable O to O induce O p21 O / O WAF1 O promoter O activation O except O with O endogenous O wt O - O p53 O on O SH O - O SY5Y O cells O where O transfection O with O IGR O - O NB8 O significantly O augmented O the O transcriptional O activation O of O the O p21 O / O Waf O - O 1 O promoter O ( O Figure O 5A O ) O . O Studies O by O other O authors O have O reported O the O interaction O between O the O C O - O terminal O domain O and O another O region O that O impedes O the O active O conformation O of O p53 O , O suggesting O an O allosteric O model O for O p53 O activity O regulation O ( O 30 O ) O . O Such O events O have O been O demonstrated O for O the O 342 O - O stop O mutant O , O generated O by O mutagenesis O , O which O can O modulate O transactivation O , O growth O and O apoptosis O ( O 31 O ) O . O Moreover O , O Harms O and O Chen O ( O 32 O ) O reported O that O the O C O - O terminal O basic O domain O inhibits O induction O of O the O proapoptotic O target O gene O insulin O - O like O growth O factor O binding O protein O 3 O , O suggesting O that O IGR O - O NB8 O might O induce O this O gene O . O IGR O - O N O - O 91 O had O an O abnormally O high O molecular O weight O protein O due O to O the O duplication O of O wild O - O type O exons O 7 O - O 8 O - O 9 O , O thus O affecting O the O DBD O and O OD O ; O and O LAN O - O 1 O , O with O a O mutation O at O codon O 182 O ( O Cys O - O - O > O stop O ) O concurred O with O an O earlier O report O showing O extremely O low O levels O of O mRNA O and O undetectable O protein O expression O ( O 9 O ) O . O Notably O , O all O the O p53 O variants O , O including O SK O - O N O - O AS O ( O beta O isoform O ) O and O IGR O - O NB8 O ( O C O - O terminal O truncated O p53 O ) O , O elicited O a O total O lack O of O p21 O promoter O activation O . O In O particular O , O the O p53 O beta O isoform O was O unable O to O induce O endogenous O p21 O expression O in O SK O - O N O - O AS O ( O Figure O 6 O ) O , O concurring O with O data O obtained O from O in O vitro O transfection O experiments O in O H1299 O cells O by O Bourdon O et O al O . O ( O 22 O ) O . O For O the O IGR O - O N O - O 91 O cells O , O although O p53 O was O mutated O and O unable O to O transactivate O the O p21 O / O WAF1 O promoter O , O the O FASAY O global O test O was O not O conclusive O since O ~ O 80 O % O of O colonies O were O white O and O nearly O 20 O % O ( O see O also O Table O 2 O ) O , O though O not O enough O , O were O red O . O Moreover O , O in O this O particular O line O , O standard O sequencing O on O cDNA O using O primers O located O within O each O exon O as O used O for O routine O tumor O analysis O was O unable O to O detect O any O anomalies O in O p53 O genetic O status O ( O data O not O shown O ) O . O These O results O enlighten O the O limit O of O the O conventional O tests O to O detect O a O transcription O inactivation O of O p53 O brought O by O duplication O within O the O DBD O . O Analysis O of O p53 O genomic O status O was O explored O by O FISH O experiments O , O in O search O for O a O potential O biallelic O inactivation O of O p53 O , O with O a O mutation O of O one O allele O and O a O deletion O of O the O second O one O . O This O situation O was O indeed O clearly O observed O in O IGR O - O N O - O 91 O and O SK O - O N O - O AS O cell O lines O , O with O an O unambiguous O loss O of O one O chromosome O 17p O arm O in O all O cells O of O both O . O SK O - O N O - O BE O ( O 2 O ) O , O LAN O - O 1 O and O IGR O - O NB O - O 8 O cell O lines O showed O a O more O complex O genomic O situation O which O should O be O relevant O of O variable O copy O numbers O of O chromosome O 17 O bearing O in O most O cases O ( O LAN O - O 1 O ) O or O in O all O cases O [ O SKN O - O BE O ( O 2 O ) O , O IGR O - O NB8 O ] O the O mutated O characteristic O p53 O allele O . O Our O data O therefore O clearly O demonstrate O that O each O technique O has O a O role O and O a O combination O of O techniques O is O required O in O order O to O correctly O define O the O p53 O phenotype O and O genotype O in O tumor O and O particularly O in O NB O cells O . O Our O data O enlighten O a O high O frequency O of O the O C O - O terminal O abnormalities O ( O 3 O / O 5 O mutated O ) O in O NB O cell O lines O . O For O SK O - O N O - O AS O and O IGR O - O NB8 O , O a O part O of O the O oligomerization O domain O was O lost O and O IGR O - O N O - O 91 O gained O an O extra O oligomerization O domain O . O According O to O FASAY O assay O the O p53 O expressed O in O IGR O - O N O - O 91 O still O specifically O bind O DNA O but O not O the O p53 O expressed O in O SK O - O N O - O AS O and O IGR O - O NB8 O in O agreement O with O previous O published O data O obtained O by O electrophoretic O mobility O shift O assay O ( O 33 O ) O . O With O regards O to O biological O relevance O , O different O mutants O within O the O DBD O vary O in O their O oncogenicity O . O They O are O classified O into O two O types O depending O of O the O location O of O the O mutation O , O mutations O of O class O I O occur O in O the O DNA O contact O areas O , O while O class O II O mutations O occur O in O areas O important O for O the O conformational O stability O of O p53 O protein O ( O 30 O ) O . O Although O both O class O I O and O class O II O mutants O have O loss O its O ability O to O specifically O bind O DNA O , O class O II O mutations O have O been O shown O to O be O more O oncogenic O than O class O I O .

O The O biological O role O of O the O C O - O terminal O mutants O needs O now O to O be O thoroughly O investigated O in O NB O tumors O . O MUC1 O alters O oncogenic O events O and O transcription O in O human B breast O cancer O cells O Abstract O Introduction O MUC1 O is O an O oncoprotein O whose O overexpression O correlates O with O aggressiveness O of O tumors O and O poor O survival O of O cancer O patients B . O Many O of O the O oncogenic O effects O of O MUC1 O are O believed O to O occur O through O interaction O of O its O cytoplasmic O tail O with O signaling O molecules O . O As O expected O for O a O protein O with O oncogenic O functions O , O MUC1 O is O linked O to O regulation O of O proliferation O , O apoptosis O , O invasion O , O and O transcription O . O Methods O To O clarify O the O role O of O MUC1 O in O cancer O , O we O transfected O two O breast O cancer O cell O lines O ( O MDA O - O MB O - O 468 O and O BT O - O 20 O ) O with O small O interfering O ( O si O ) O RNA O directed O against O MUC1 O and O analyzed O transcriptional O responses O and O oncogenic O events O ( O proliferation O , O apoptosis O and O invasion O ) O . O Results O Transcription O of O several O genes O was O altered O after O transfection O of O MUC1 O siRNA O , O including O decreased O MAP2K1 O ( O MEK1 O ) O , O JUN O , O PDGFA O , O CDC25A O , O VEGF O and O ITGAV O ( O integrin O alpha O v O ) O , O and O increased O TNF O , O RAF1 O , O and O MMP2 O . O Additional O changes O were O seen O at O the O protein O level O , O such O as O increased O expression O of O c O - O Myc O , O heightened O phosphorylation O of O AKT O , O and O decreased O activation O of O MEK1 O / O 2 O and O ERK1 O / O 2 O . O These O were O correlated O with O cellular O events O , O as O MUC1 O siRNA O in O the O MDA O - O MB O - O 468 O line O decreased O proliferation O and O invasion O , O and O increased O stress O - O induced O apoptosis O . O Intriguingly O , O BT O - O 20 O cells O displayed O similar O levels O of O apoptosis O regardless O of O siRNA O , O and O actually O increased O proliferation O after O MUC1 O siRNA O . O Conclusion O These O results O further O the O growing O knowledge O of O the O role O of O MUC1 O in O transcription O , O and O suggest O that O the O regulation O of O MUC1 O in O breast O cancer O may O be O more O complex O than O previously O appreciated O . O The O differences O between O these O two O cell O lines O emphasize O the O importance O of O understanding O the O context O of O cell O - O specific O signaling O events O when O analyzing O the O oncogenic O functions O of O MUC1 O , O and O caution O against O generalizing O the O results O of O individual O cell O lines O without O adequate O confirmation O in O intact O biological O systems O . O Introduction O MUC1 O is O the O founding O member O of O the O mucin O family O : O proteins O characterized O by O heavy O O O - O glycosylation O centering O around O a O variable O number O of O tandem O repeats O that O are O rich O in O serine O and O threonine O residues O [ O 1 O , O 2 O ] O . O MUC1 O is O a O transmembrane O heterodimer O with O one O subunit O solely O extracellular O ( O MUC1 O - O EX O ) O , O and O the O other O subunit O composed O of O a O short O extracellular O stem O , O a O single O transmembrane O domain O , O and O the O cytoplasmic O tail O ( O together O called O the O MUC1 O - O CT O ) O . O MUC1 O possesses O both O pro O - O and O anti O - O adhesive O capacities O , O as O the O MUC1 O - O EX O provides O binding O sites O for O a O variety O of O adhesion O proteins O , O while O its O large O size O and O extended O structure O prevents O cell O - O cell O contact O [ O 3 O - O 5 O ] O . O Initially O described O as O a O tumor O antigen O overexpressed O in O > O 90 O % O of O breast O cancers O , O MUC1 O is O now O known O to O be O an O oncogene O with O roles O in O both O tumor O formation O and O progression O [ O 1 O , O 6 O ] O . O Mouse B studies O have O been O integral O to O the O current O understanding O of O MUC1 O in O cancer O . O Muc1 O knockout O mice B ( O Muc1 O - O / O - O ; O MUC1 O is O human B ; O Muc1 O is O mouse B ) O show O a O reduction O in O tumorigenic O phenotype O when O crossed O onto O mice B overexpressing O the O Wnt O - O 1 O [ O 7 O ] O or O polyomavirus O middle O T O antigen O [ O 8 O ] O oncogenes O in O the O mammary O gland O . O In O contrast O , O MUC1 O overexpression O in O the O mammary O gland O drives O tumor O formation O [ O 9 O ] O , O indicating O that O MUC1 O is O a O true O oncogene O . O Many O of O the O oncogenic O effects O of O MUC1 O stem O from O its O cytoplasmic O tail O , O which O binds O to O several O proteins O implicated O in O cancer O , O including O c O - O Src O [ O 10 O , O 11 O ] O and O the O epidermal O growth O factor O receptor O ( O EGFR O ) O family O [ O 12 O , O 13 O ] O . O MUC1 O stimulates O mitogen O activated O protein O kinase O ( O MAPK O ) O signaling O through O the O extracellular O signal O regulated O kinases O ( O ERK1 O / O 2 O ) O [ O 12 O , O 14 O ] O ; O this O can O occur O through O MUC1 O association O with O Grb2 O and O son O of O sevenless O to O activate O Ras O [ O 15 O ] O . O ERK1 O / O 2 O signaling O is O commonly O stimulated O by O the O Ras O - O Raf O - O MEK O ( O MAPK O and O ERK O kinase O ) O cascade O downstream O of O mitogens O such O as O EGFR O [ O 16 O ] O , O and O regulates O transcription O via O factors O like O the O activator O protein O - O 1 O complex O . O Loss O of O MUC1 O can O reduce O EGFR O expression O [ O 17 O ] O , O providing O another O means O of O affecting O MAPK O signaling O . O Our O results O describe O a O novel O mechanism O by O which O MUC1 O regulates O the O ERK1 O / O 2 O pathway O , O through O modulating O transcription O of O the O genes O encoding O MEK1 O , O Raf O - O 1 O , O and O c O - O Jun O . O MUC1 O expression O correlates O with O increased O survival O in O response O to O cytotoxic O or O oxidative O agents O [ O 18 O - O 21 O ] O , O and O can O activate O the O phosphoinositol O - O 3 O kinase O - O AKT O pathway O as O part O of O an O anti O - O apoptotic O response O [ O 18 O ] O .

O Discussion O This O report O describes O both O the O transcriptional O alterations O seen O after O transfection O with O MUC1 O siRNA O in O human B breast O cancer O cells O and O the O effects O on O events O such O as O apoptosis O and O proliferation O . O The O two O cell O lines O used O ( O MDA O - O MB O - O 468 O and O BT O - O 20 O ) O were O chosen O for O high O expression O of O MUC1 O and O a O substantial O ( O 50 O % O to O 75 O % O ) O , O consistent O decrease O in O MUC1 O expression O after O siRNA O . O Both O lines O have O epithelial O morphology O , O form O tumors O slowly O in O nude B mice I [ O 37 O ] O , O have O mutant O p53 O [ O 39 O , O 40 O ] O , O express O EGFR O [ O 37 O ] O , O and O lack O estrogen O receptor O alpha O [ O 41 O ] O . O One O striking O difference O between O these O lines O , O however O , O is O their O response O to O MUC1 O siRNA O . O MDA O - O MB O - O 468 O cells O behave O as O expected O for O loss O of O an O oncogene O : O MUC1 O siRNA O correlates O with O increased O apoptosis O in O response O to O stress O , O decreased O proliferation O , O and O reduced O invasion O . O In O contrast O , O BT O . O siMUC1 O cells O proliferate O more O rapidly O than O BT O . O siLuc O cells O with O little O effect O on O apoptosis O . O Much O of O the O phenotype O of O these O cells O can O be O understood O in O light O of O protein O levels O and O transcriptional O activity O after O MUC1 O siRNA O . O As O mentioned O , O both O MDA O - O MB O - O 468 O and O BT O - O 20 O display O increased O pAKT O after O MUC1 O siRNA O , O but O the O ratio O of O active O to O total O AKT O is O considerably O higher O in O the O BT O - O 20 O line O , O which O may O help O these O cells O resist O the O increased O apoptosis O expected O with O loss O of O MUC1 O . O Myc O levels O are O also O higher O in O both O cell O lines O after O MUC1 O siRNA O , O although O the O ability O of O Myc O to O promote O proliferation O and O apoptosis O in O different O cellular O contexts O [ O 42 O ] O complicates O the O interpretation O of O this O finding O . O Both O cell O lines O show O reduced O transcription O of O VEGF O , O PDGFA O , O PDGFB O , O and O MAP2K1 O ( O MEK1 O ) O after O MUC1 O siRNA O . O The O genes O encoding O vascular O endothelial O growth O factor O ( O VEGF O ) O and O the O A O and O B O chains O of O platelet O - O derived O growth O factor O ( O PDGF O - O A O and O PDGF O - O B O ) O are O interesting O as O these O proteins O have O been O heavily O implicated O in O angiogenesis O , O suggesting O a O novel O function O for O MUC1 O in O regulating O this O process O . O Vascular O endothelial O growth O factor O expression O in O cancer O is O linked O to O tumor O growth O and O metastasis O [ O 43 O , O 44 O ] O ; O platelet O - O derived O growth O factor O is O also O angiogenic O , O but O has O an O additional O role O in O stimulating O desmoplasia O [ O 45 O ] O . O Reduced O transcription O of O these O genes O after O MUC1 O siRNA O suggests O that O MUC1 O may O foster O angiogenesis O and O stromal O proliferation O , O although O this O must O be O confirmed O in O a O more O appropriate O model O system O . O Decreased O MAP2K1 O ( O MEK1 O ) O transcription O after O MUC1 O siRNA O provides O a O novel O mechanism O by O which O MUC1 O can O affect O the O ERK1 O / O 2 O MAPK O pathway O . O MUC1 O has O often O been O linked O to O the O Ras O - O Raf O - O MEK O - O ERK O cascade O [ O 12 O , O 34 O - O 36 O , O 46 O ] O , O and O at O least O two O mechanisms O by O which O MUC1 O can O alter O MAPK O signaling O have O been O described O : O MUC1 O interaction O with O and O phosphorylation O by O the O EGFR O family O [ O 12 O , O 13 O ] O , O and O MUC1 O binding O to O the O Grb2 O / O Sos O complex O that O activates O Ras O [ O 46 O ] O . O Reduction O of O MEK1 O levels O after O MUC1 O siRNA O agrees O with O the O role O of O MUC1 O in O strengthening O MAPK O signaling O , O and O indicates O that O MUC1 O can O regulate O both O the O transcription O and O activity O of O members O of O this O pathway O . O Two O additional O MAPK O pathway O members O are O altered O specifically O in O BT O . O siMUC1 O , O with O no O corresponding O change O in O 468 O . O siMUC1 O cells O . O These O genes O are O RAF1 O and O JUN O which O are O increased O and O decreased O , O respectively O , O after O MUC1 O siRNA O . O Raf O - O 1 O and O c O - O Jun O both O function O outside O of O the O ERK1 O / O 2 O MAPK O pathway O , O which O may O explain O the O seeming O paradox O of O increased O RAF1 O transcription O with O simultaneous O decreases O in O MAP2K1 O and O JUN O . O Specifically O , O Raf O - O 1 O can O inhibit O ASK1 O ( O apoptosis O signal O - O regulated O kinase O 1 O ) O upstream O of O p38 O and O JNK O ( O Jun O N O - O terminal O kinase O ) O [ O 38 O ] O . O ASK1 O phosphorylates O JNK O in O response O to O stress O , O resulting O in O activation O of O c O - O Jun O and O stimulation O of O apoptosis O [ O 47 O ] O , O indicating O that O the O coordinate O up O - O regulation O of O RAF1 O and O down O - O regulation O of O JUN O may O provide O a O potent O anti O - O apoptotic O effect O in O BT O . O siMUC1 O . O Regulation O of O life O and O death O is O also O a O hallmark O of O the O CDC25A O and O TNF O gene O products O . O CDC25A O is O a O phosphatase O that O stimulates O cell O cycle O progression O [ O 48 O ] O , O thus O the O effects O of O its O decrease O in O BT O . O siMUC1 O are O unclear O in O light O of O the O increased O proliferation O of O these O cells O . O However O , O the O CDC25 O proteins O ( O A O , O B O , O and O C O ) O were O recently O shown O to O have O greater O functional O overlap O than O was O previously O thought O [ O 49 O ] O , O suggesting O that O the O other O two O isoforms O may O compensate O for O reduced O CDC25A O levels O . O TNF O encodes O tumor O necrosis O factor O ( O TNF O ) O alpha O , O known O for O its O potent O , O cell O type O - O specific O control O of O life O and O death O . O In O tumor O cells O , O TNF O alpha O expression O can O promote O proliferation O and O inhibit O apoptosis O [ O 50 O ] O , O suggesting O that O increased O TNF O transcription O in O BT O . O siMUC1 O could O contribute O to O the O increased O proliferation O seen O in O these O cells O . O Interestingly O , O the O increase O in O TNF O is O accompanied O by O decreased O transcription O of O TIMP3 O , O encoding O tissue O inhibitor O of O metalloproteinases O ( O TIMP O ) O 3 O . O The O TIMP O family O disrupts O the O function O of O matrix O metalloproteinases O ( O MMPs O ) O , O generally O resulting O in O decreased O invasion O [ O 51 O ] O . O TIMP3 O is O unique O in O that O it O can O also O inhibit O TNF O alpha O converting O enzyme O ( O TACE O ) O , O which O activates O TNF O alpha O by O cleaving O it O from O the O cell O surface O [ O 50 O ] O . O Reduced O expression O of O TIMP3 O would O , O therefore O , O foster O signaling O through O TNF O alpha O by O releasing O inhibition O of O TNF O alpha O converting O enzyme O . O In O agreement O with O this O , O TIMP3 O can O promote O apoptosis O [ O 52 O ] O ; O thus O , O its O down O - O regulation O in O BT O . O siMUC1 O provides O another O mechanism O by O which O these O cells O are O able O to O resist O the O increased O apoptosis O expected O with O loss O of O MUC1 O . O Another O TIMP O target O responds O to O MUC1 O siRNA O , O as O 468 O . O siMUC1 O cells O show O significantly O increased O expression O of O MMP2 O ( O encoding O MMP O - O 2 O / O gelatinase O A O ) O , O the O product O of O which O degrades O type O IV O collagen O [ O 52 O ] O . O In O breast O cancer O , O the O ratio O of O active O to O latent O MMP O - O 2 O increases O with O tumor O progression O ; O MMP O - O 2 O may O facilitate O both O angiogenesis O and O metastasis O [ O 52 O ] O . O Its O increase O after O loss O of O MUC1 O is O , O therefore O , O unexpected O , O but O at O least O two O factors O may O clarify O this O result O . O First O , O though O MMP O - O 2 O levels O are O increased O in O mouse B mammary O tumors O , O its O expression O is O confined O to O the O stroma O [ O 53 O ] O , O suggesting O that O increased O MMP2 O transcription O after O loss O of O the O epithelium O - O specific O MUC1 O might O reflect O a O shift O towards O a O more O mesenchymal O phenotype O . O Second O , O MMP O - O 2 O levels O are O increased O by O overexpression O of O erbB2 O [ O 52 O ] O ; O previous O studies O have O shown O that O erbB2 O and O Muc1 O expression O are O mutually O exclusive O in O mammary O tumors O [ O 27 O ] O , O implying O that O MMP2 O might O be O part O of O a O transcriptional O profile O linked O to O low O MUC1 O levels O . O It O is O intriguing O that O , O despite O increased O MMP2 O transcription O , O invasion O is O decreased O in O 468 O . O siMUC1 O cells O , O even O on O collagen O IV O . O This O may O reflect O insufficient O activation O of O MMP O - O 2 O , O as O the O precursor O protein O must O be O cleaved O for O enzymatic O function O [ O 52 O ] O . O Alternatively O , O the O slowed O invasion O of O these O cells O may O relate O to O impaired O adhesion O resulting O from O decreased O transcription O of O ITGAV O and O ITGB1 O ( O alpha O v O and O beta O 1 O integrins O , O respectively O ) O . O Integrin O signaling O is O tied O to O life O - O or O - O death O decisions O in O epithelial O cells O , O and O integrin O expression O is O vital O for O processes O from O wound O healing O to O metastasis O [ O 54 O ] O . O Integrin O alpha O v O beta O 3 O is O implicated O in O facilitating O metastasis O of O breast O cancer O cells O to O bone O [ O 55 O ] O ; O decreased O transcription O of O ITGAV O after O MUC1 O siRNA O may O , O therefore O , O suggest O that O MUC1 O is O involved O in O this O lethal O process O as O well O . O The O MUC1 O oncogene O has O been O linked O to O apoptosis O [ O 18 O , O 20 O , O 26 O ] O , O proliferation O [ O 17 O ] O , O and O transcription O [ O 21 O , O 23 O - O 25 O ] O in O cancer O . O However O , O the O two O cell O lines O chosen O for O our O study O display O very O different O responses O to O MUC1 O siRNA O , O indicating O that O regulation O of O MUC1 O in O breast O cancer O is O likely O quite O complex O and O cautioning O against O over O - O generalization O of O results O from O individual O cell O lines O . O Previous O reports O suggest O that O , O though O most O studies O outline O a O clearly O oncogenic O role O for O MUC1 O in O breast O cancer O , O the O exact O details O may O vary O depending O on O factors O such O as O cell O type O and O signaling O context O . O For O example O , O MUC1 O stimulates O Fas O - O mediated O apoptosis O in O CHO O cells O [ O 26 O ] O , O quite O unlike O the O inhibition O of O apoptosis O seen O in O other O cell O lines O . O Similarly O , O though O MUC1 O drives O mammary O oncogenesis O in O its O own O right O [ O 9 O ] O and O facilitates O tumorigenesis O driven O by O other O oncogenes O [ O 7 O , O 8 O ] O , O Muc1 O is O selectively O down O - O regulated O in O c O - O neu O - O induced O mouse B mammary O tumors O [ O 27 O ] O , O indicating O that O the O context O of O oncogenic O signaling O is O vital O to O understanding O the O function O of O MUC1 O . O Thus O , O it O is O important O to O consider O the O relative O levels O of O knockdown O of O MUC1 O in O the O two O cell O lines O : O BT O - O 20 O cells O reduce O MUC1 O expression O after O siRNA O less O strongly O than O do O MDA O - O MB O - O 468 O ( O 50 O % O versus O 75 O % O knockdown O , O respectively O ) O . O As O MUC1 O serves O as O a O scaffold O [ O 11 O ] O , O overexpression O of O MUC1 O relative O to O its O associated O signaling O proteins O might O create O a O dilution O effect O , O sequestering O signal O transducers O away O from O each O other O ; O this O would O be O relieved O by O MUC1 O siRNA O . O Thus O , O enough O MUC1 O may O be O retained O in O BT O . O siMUC1 O cells O for O its O oncogenic O effects O , O while O signaling O complex O formation O would O be O enhanced O by O lowering O the O amount O of O MUC1 O relative O to O other O signaling O proteins O . O Conclusion O The O contrast O between O the O MDA O - O MB O - O 468 O and O BT O - O 20 O lines O in O response O to O MUC1 O siRNA O serves O as O a O reminder O that O simplified O models O such O as O cell O lines O fail O to O encompass O the O complexity O of O intact O biological O systems O . O This O report O describes O transcriptional O alterations O seen O after O MUC1 O knockdown O : O decreased O transcription O of O MAP2K1 O , O VEGF O , O PDGFA O , O ITGAV O , O TIMP3 O , O CDC25A O , O and O JUN O , O and O increased O transcription O of O MMP2 O , O TNF O , O and O RAF1 O . O The O alterations O in O MAP2K1 O , O RAF1 O , O and O JUN O represent O a O novel O means O by O which O MUC1 O can O affect O ERK1 O / O 2 O signaling O : O transcriptional O regulation O of O MAPK O pathway O members O . O Oncogenic O events O are O also O altered O in O both O cell O lines O after O MUC1 O siRNA O .

O Here O , O we O have O determined O the O crystal O structure O of O RdgC O from O Pseudomonas B aeruginosa I . O The O J O - O shaped O monomer O has O a O unique O fold O and O can O be O divided O into O three O structural O domains O : O tip O domain O , O center O domain O and O base O domain O .

O INTRODUCTION O Homologous O recombination O systems O contribute O to O the O maintenance O of O genome O integrity O and O are O essential O for O the O repair O of O stalled O replication O forks O ( O 1 O ) O . O Genetic O studies O of O the O recombination O - O dependent O growth O C O ( O rdgC O ) O gene O in O bacterial O systems O have O suggested O that O it O is O involved O in O DNA O replication O and O recombination O ( O 2 O , O 3 O ) O .

O The O net O charge O of O a O dimer O would O be O - O 12 O ( O or O - O 8 O ) O , O if O we O assume O none O ( O or O all O ) O of O histidines O to O be O positively O charged O . O The O electrostatic O potential O at O the O molecular O surface O of O RdgC O dimer O shows O that O the O charge O distribution O on O the O protein O surface O is O highly O nonuniform O ( O Figure O 4A O ) O . O Since O the O inner O surface O of O the O RdgC O dimer O is O rich O in O conserved O , O positively O charged O residues O and O the O diameter O of O the O central O hole O ( O ~ O 30 O A O ) O is O approximately O similar O to O that O of O other O toroidal O DNA O - O binding O proteins O ( O 26 O ) O , O it O appears O likely O that O RdgC O dimers O bind O dsDNA O through O the O central O hole O . O Despite O extensive O co O - O crystallization O and O soaking O trials O with O linear O dsDNAs O of O different O lengths O ( O 14 O - O mer O , O 16 O - O mer O and O 18 O - O mer O ) O , O we O could O not O locate O the O bound O DNA O experimentally O . O We O attribute O this O difficulty O to O the O nature O of O sequence O - O nonspecific O DNA O binding O by O RdgC O . O Therefore O , O we O built O a O crude O model O of O a O DNA O complex O of O the O RdgC O dimer O by O fitting O dsDNA O into O the O central O hole O ( O Figure O 4B O ) O .

O This O is O consistent O with O an O apparent O lack O of O an O ATP O - O binding O pocket O in O the O RdgC O dimer O structure O . O In O order O to O identify O the O residues O that O are O important O for O dsDNA O binding O , O we O carried O out O mutational O analyses O . O The O residues O for O mutagenesis O were O selected O on O the O basis O of O the O modeled O complex O between O RdgC O dimer O and O dsDNA O , O together O with O sequence O conservation O ( O Figure O 4C O ) O . O We O prepared O eleven O point O mutants O ( O R4A O , O K70D O , O R81D O , O F120A O , O R122D O , O K146A O , O R198A O , O R208A O , O R211D O , O Q212A O and O R252A O ) O . O These O eleven O mutated O residues O are O well O conserved O among O RdgC O proteins O . O Eight O mutants O ( O R4A O , O K70D O , O R81D O , O R122D O , O K146A O , O R198A O , O R208A O and O R252A O ) O had O a O lower O affinity O for O dsDNA O than O the O wild O - O type O RdgC O ( O Figure O 4D O ) O . O These O eight O mutated O residues O are O indicated O by O blue O squares O below O the O aligned O sequences O in O Figure O 3 O . O This O result O indicates O that O dsDNA O binds O to O the O inside O surface O around O the O central O hole O of O the O RdgC O dimer O , O since O the O mutated O residues O are O located O on O the O inner O surface O of O the O RdgC O dimer O . O It O is O worth O mentioning O that O a O single O mutation O introduces O two O alterations O per O RdgC O dimer O . O The O three O mutants O ( O F120A O , O R211D O and O Q212A O ) O were O prepared O to O investigate O whether O dimerization O of O RdgC O is O crucial O for O dsDNA O binding O . O Phe120 O is O a O key O residue O located O in O the O inter O - O subunit O interface O A O ( O Figure O 2B O ) O , O while O Arg211 O makes O hydrogen O bonds O in O the O interface O B O ( O Figure O 2D O ) O and O Gln212 O is O involved O in O both O intra O - O and O inter O - O subunit O interactions O ( O Figure O 2D O ) O . O dsDNA O binding O by O the O F120A O mutant O is O considerably O weakened O , O compared O to O either O the O R211D O or O Q212A O mutant O ( O Figure O 4D O ) O . O This O result O suggests O that O destabilization O of O the O ring O - O shaped O architecture O of O the O RdgC O dimer O is O deleterious O for O tight O dsDNA O binding O and O that O interface O A O is O probably O more O important O than O interface O B O for O dsDNA O binding O . O dsDNA O - O binding O affinity O of O the O Q212A O mutant O was O lower O than O the O wild O type O ( O Figure O 4D O ) O , O whereas O that O of O the O R211D O mutant O was O comparable O to O the O wild O type O ( O Figure O 4D O ) O . O This O result O suggests O that O disruption O of O the O inter O - O subunit O interface O B O is O also O detrimental O for O dsDNA O binding O but O to O a O smaller O extent O than O disruption O of O the O interface O A O . O It O further O suggests O that O the O side O chain O of O Arg211 O is O not O involved O in O recognizing O dsDNA O . O It O is O interesting O that O the O DNA O complex O for O wild O type O forms O a O distinct O band O ( O lane O 3 O in O Figure O 4D O ) O , O as O opposed O to O a O more O diffuse O band O as O one O would O expect O if O the O complexes O contained O different O numbers O of O RdgC O dimers O .

O RdgC O inhibition O of O the O RecA O function O by O a O simple O competition O mechanism O at O the O cellular O concentration O of O RdgC O clearly O requires O a O much O higher O affinity O for O DNA O by O RdgC O than O RecA O . O Possible O protein O - O protein O interactions O between O RdgC O dimers O might O have O a O profound O effect O on O the O affinity O for O DNA O , O when O a O large O number O of O RdgC O dimers O are O bound O on O a O duplex O DNA O . O If O only O one O of O the O two O inter O - O subunit O interfaces O can O open O up O and O the O 2 O - O fold O symmetry O axes O of O the O RdgC O dimers O are O misaligned O sufficiently O , O the O escape O of O DNA O from O a O linear O array O of O interacting O RdgC O dimers O would O be O extremely O difficult O . O Alternatively O , O both O inter O - O subunit O interfaces O of O each O dimer O may O open O up O simultaneously O . O A O line O of O indirect O evidence O for O the O possible O protein O - O protein O interactions O between O RdgC O dimers O is O provided O by O the O cooperative O binding O of O RdgC O to O DNA O ( O 7 O ) O . O Cooperativity O of O RdgC O binding O may O be O caused O by O local O and O distant O protein O - O protein O interactions O ( O 7 O ) O . O A O kind O of O side O - O by O - O side O interaction O between O two O adjacent O molecules O of O RdgC O dimer O is O present O in O the O crystal O , O burying O an O accessible O surface O area O of O ~ O 750 O A O 2 O at O the O interface O .

O This O may O explain O the O observed O DNA O bending O by O RdgC O , O which O was O speculated O to O be O a O necessary O step O in O the O working O mechanism O of O RdgC O , O if O one O can O assume O that O the O strong O protein O - O protein O interactions O in O the O crystal O were O relevant O for O protein O - O protein O interactions O in O solution O ( O 7 O ) O . O RdgC O protein O was O shown O to O have O a O potent O effect O on O RecA O protein O - O promoted O DNA O strand O exchange O in O E B . I coli I ( O 1 O ) O . O In O a O series O of O experiments O , O RdgC O was O added O after O RecA O filaments O had O formed O on O the O ssDNA O and O 5 O min O after O the O linear O dsDNA O was O added O .

O This O suggests O that O the O binding O affinity O of O RdgC O to O dsDNA O is O considerably O higher O than O that O of O RecA O . O The O high O affinity O of O RdgC O could O be O explained O by O its O ring O shape O and O the O suggested O mode O of O DNA O binding O . O Tetrameric O species O of O E B .

O Higher O affinity O for O DNA O of O the O tetrameric O species O could O be O understood O , O if O the O formation O of O a O tetramer O in O solution O involves O a O protein O - O protein O interaction O similar O to O the O side O - O by O - O side O interaction O between O two O adjacent O RdgC O dimers O in O the O crystal O , O although O there O is O no O experimental O evidence O . O Obviously O , O there O are O still O many O open O questions O that O need O to O be O addressed O in O future O biochemical O experiments O . O SUMMARY O The O crystal O structure O of O RdgC O , O a O recombination O - O associated O DNA O - O binding O protein O , O determined O in O this O study O reveals O that O the O polypeptide O chain O is O uniquely O folded O and O two O monomers O associate O to O form O a O ring O - O shaped O dimer O with O a O central O hole O of O ~ O 30 O A O diameter O . O The O inner O surface O around O the O central O hole O is O rich O in O positively O charged O residues O . O These O structural O features O suggest O that O dsDNA O runs O through O the O central O hole O when O it O binds O to O RdgC O dimers O . O This O idea O is O supported O by O our O mutational O studies O , O which O indicate O that O the O conserved O , O positively O charged O residues O around O the O central O hole O are O important O for O dsDNA O binding O . O The O toroidal O architecture O of O the O RdgC O dimer O provides O a O sound O framework O for O a O better O understanding O of O its O role O in O homologous O recombination O .

O Closure O of O port O sites O , O especially O those O measuring O 10 O mm O or O more O , O has O been O recommended O to O avoid O such O an O event O . O Case O presentation O We O herein O report O the O only O case O of O a O port O site O hernia O among O a O series O 52 O consecutive O cases O of O laparoscopy O - O assisted O distal O gastrectomy O ( O LADG O ) O carried O out O by O our O unit O between O July O 2002 O and O March O 2007 O . O In O this O case O the O small O bowel O herniated O and O incarcerated O through O the O port O site O on O day O 4 O after O LADG O despite O closure O of O the O fascia O . O Initial O manifestations O experienced O by O the O patient B , O possibly O due O to O obstruction O , O and O including O mild O abdominal O pain O and O nausea O , O occurred O on O the O third O day O postoperatively O . O The O definitive O diagnosis O was O made O on O day O 4 O based O on O symptoms O related O to O leakage O from O the O duodenal O stump O , O which O was O considered O to O have O developed O after O severe O obstruction O of O the O bowel O . O Re O - O operation O for O reduction O of O the O incarcerated O bowel O and O tube O duodenostomy O with O peritoneal O drainage O were O required O to O manage O this O complication O . O Conclusion O We O present O this O case O report O and O review O of O literature O to O discuss O further O regarding O methods O of O fascial O closure O after O laparoscopic O surgery O . O Introduction O Bowel O herniation O through O the O fascial O defect O created O by O the O entry O of O trocars O is O now O recognized O as O a O rare O but O potentially O serious O complication O of O laparoscopic O surgery O [ O 1 O ] O . O Although O port O site O herniation O is O an O infrequent O complication O , O there O are O still O some O reports O of O port O site O herniation O after O these O procedures O , O even O with O closure O of O trocar O sites O [ O 1 O , O 2 O ] O . O The O following O report O describes O a O case O of O a O trocar O site O hernia O that O evolved O into O leakage O from O the O duodenal O stump O after O laparoscopy O - O assisted O distal O gastrectomy O ( O LADG O ) O . O Progression O occurred O because O of O complete O obstruction O of O the O incarcerated O bowel O after O a O Roux O - O en O - O Y O reconstruction O . O We O describe O the O significance O of O complete O closure O of O the O fascial O defect O at O the O trocar O site O including O the O peritoneum O in O the O prevention O of O this O condition O , O as O well O as O the O importance O of O early O diagnosis O to O avoid O serious O subsequent O events O . O Case O presentation O An O 80 O - O year O - O old O man B was O found O to O have O early O gastric O cancer O during O his O yearly O check O - O up O by O gastrointestinal O endoscopy O . O He O was O 158 O cm O in O height O and O weighed O 62 O kg O . O Gastrointestinal O endoscopy O showed O a O depressed O lesion O that O was O diagnosed O as O early O gastric O cancer O by O pathological O examination O of O biopsy O specimens O . O He O underwent O LADG O with O regional O lymph O node O dissection O ( O D1 O including O the O nodes O surrounding O the O origin O of O left O gastric O artery O ) O . O A O 12 O - O mm O trocar O for O the O laparoscope O was O placed O in O the O umbilicus O . O Pneumoperitoneum O was O then O established O with O carbon O dioxide O and O the O intraperitoneal O pressure O was O maintained O at O 10 O mm O Hg O . O Two O more O 12 O - O mm O trocars O were O inserted O in O the O midclavicular O line O below O the O costal O margin O and O 2 O cm O above O the O umbilicus O on O each O of O both O flanks O and O were O used O for O active O surgical O instruments O . O All O trocars O used O were O the O non O - O bladed O type O . O The O specimen O was O removed O through O a O small O medial O incision O which O was O 55 O mm O in O length O placed O after O resection O of O the O stomach O , O and O then O Roux O - O en O - O Y O reconstruction O ( O RY O ) O was O carried O out O ( O Fig O . O 1 O ) O . O A O tubular O shaped O drainage O tube O 10 O mm O in O diameter O was O inserted O and O placed O through O the O upper O trocar O site O made O on O the O right O flank O . O Wound O defect O at O the O umbilical O port O site O was O sutured O completely O including O the O peritoneum O with O 0 O absorbable O suture O and O fascial O incisions O at O all O other O trocar O insertion O sites O were O closed O with O 2 O - O 0 O absorbable O sutures O . O Surgical O duration O was O 263 O min O , O and O the O volume O of O blood O loss O was O less O than O 50 O mL O with O no O blood O transfusion O . O Postoperatively O , O the O patient B complained O of O an O acidic O feeling O in O his O stomach O ; O however O , O there O were O no O remarkable O abnormalities O on O biochemical O examination O of O serum O . O Radiological O findings O did O not O suggest O bowel O obstruction O until O 3 O days O postoperatively O , O although O mild O symptoms O such O as O general O malaise O and O vague O abdominal O pain O were O reported O on O day O three O . O However O , O on O day O 4 O , O the O patient B started O to O complain O of O upper O abdominal O pain O and O developed O a O high O grade O fever O ( O 38 O degrees O C O ) O . O Complete O obstruction O of O the O small O bowel O and O leakage O of O contrast O media O were O demonstrated O by O Gastrografin O swallow O and O subsequent O abdominal O computed O tomography O ( O CT O ) O . O CT O also O showed O a O mass O lesion O at O the O trocar O insertion O site O on O the O upper O left O flank O , O suggesting O herniation O through O the O port O site O ( O Fig O . O 2 O ) O . O Marked O dilatation O of O the O duodenum O including O the O horizontal O part O and O second O portion O was O observed O . O A O diagnosis O of O staple O failure O of O the O stump O of O the O duodenum O and O port O - O site O herniation O of O the O small O bowel O was O made O , O and O exploratory O laparotomy O was O carried O out O . O A O small O medial O incision O that O had O been O made O at O the O initial O surgery O was O extended O downward O to O the O umbilicus O to O open O the O peritoneal O cavity O . O As O we O expected O , O the O small O bowel O was O incarcerated O into O the O peritoneal O defect O in O the O abdominal O wall O created O by O the O trocar O placed O in O the O left O upper O flank O leading O to O complete O obstruction O of O the O bowel O ( O Fig O . O 3 O ) O . O Part O of O the O jejunum O 30 O cm O distal O from O the O ligament O of O Treitz O herniated O around O the O fascial O stitch O , O which O still O existed O at O the O time O of O the O re O - O exploration O . O The O peritoneal O cavity O was O contaminated O with O intestinal O juice O . O Close O examination O after O reduction O of O the O incarcerated O bowel O did O not O demonstrate O necrosis O of O the O intestine O , O and O thus O , O we O decided O not O to O resect O this O lesion O . O Leakage O of O intestinal O juice O through O a O pinhole O fistula O at O the O duodenal O stump O was O also O observed O . O Tube O duodenostomy O was O performed O with O an O omental O patch O used O for O closure O of O the O fistula O . O The O peritoneal O defect O was O also O closed O . O The O postoperative O course O was O fairly O good O without O high O output O of O the O intestinal O juice O leakage O or O sepsis O . O The O patient B remained O in O the O intensive O care O unit O for O 5 O days O after O re O - O operation O , O and O was O then O transferred O to O the O general O ward O . O Discussion O Port O - O site O herniation O , O which O is O one O of O the O major O complications O after O laparoscopic O procedures O [ O 1 O ] O , O sometimes O develops O into O serious O complications O , O such O as O bowel O obstruction O due O to O incarceration O into O the O fascial O defect O at O the O port O site O . O Boughey O et O al O . O have O reported O four O cases O of O Richter O ' O s O hernia O that O occurred O at O a O port O site O after O laparoscopic O surgery O [ O 1 O ] O . O They O reviewed O previous O reports O and O found O the O incidence O to O be O 0 O . O 2 O to O 3 O % O . O A O report O describes O the O incidence O of O hernia O as O 0 O . O 23 O % O for O 10 O - O mm O trocar O use O , O rising O to O 3 O . O 1 O % O for O the O 12 O - O mm O trocar O [ O 2 O ] O suggesting O that O the O wound O created O by O a O larger O port O carries O a O greater O risk O of O herniation O . O Most O surgeons O now O routinely O close O the O fascia O of O port O sites O to O prevent O this O complication O [ O 2 O ] O . O According O to O previous O reports O , O port O site O herniation O apparently O happens O more O often O with O the O use O of O bladed O type O trocars O than O non O - O bladed O type O trocars O [ O 3 O ] O . O Indeed O , O Kolata O demonstrated O that O the O wounds O made O by O the O non O - O bladed O trocar O were O narrower O than O those O created O by O cutting O tip O trocars O in O a O pig B experimental O model O [ O 4 O ] O . O Several O reports O even O concluded O that O port O sites O created O by O non O - O bladed O trocars O do O not O require O fascial O closure O [ O 3 O ] O . O However O , O the O current O case O suggests O that O thick O preperitoneum O is O a O potential O space O that O allows O for O the O development O of O bowel O herniation O even O with O the O use O of O non O - O bladed O type O trocars O . O A O previous O report O also O described O port O - O site O herniation O , O despite O the O closure O of O the O superficial O layer O of O the O fascial O defect O [ O 5 O ] O . O The O current O case O did O not O demonstrate O any O of O the O risk O factors O suggested O previously O [ O 6 O ] O ; O 1 O ) O enlargement O of O a O port O site O to O remove O specimen O ; O 2 O ) O glucose O intolerance O ; O 3 O ) O obesity O ; O or O 4 O ) O extensive O manipulation O of O the O trocar O during O relatively O prolonged O surgical O duration O , O which O might O have O enlarged O the O trocar O site O and O thus O induced O bowel O herniation O . O Therefore O , O we O recommend O closing O the O fascial O defect O , O including O the O peritoneum O , O especially O if O the O trocar O size O is O more O than O 10 O - O mm O and O in O the O presence O of O any O of O the O risk O factors O described O above O . O However O , O it O is O sometimes O difficult O to O completely O close O the O defect O , O including O the O peritoneum O , O especially O in O obese O patients B . O Shaher O reviewed O different O wound O closure O techniques O by O a O literature O search O [ O 7 O ] O . O In O this O review O , O old O methods O using O classical O instruments O including O Deschamps O needle O are O also O useful O as O well O as O special O wound O devices O designed O for O port O site O closure O . O Elashry O et O al O . O described O a O prospective O randomized O study O demonstrating O that O the O Carter O - O Thomason O device O was O faster O and O resulted O in O fewer O port O - O closure O - O related O complications O among O eight O different O techniques O tested O [ O 8 O ] O . O Insertion O of O a O SURGICEL O plug O into O the O muscular O layer O of O trocar O wounds O has O also O been O proposed O by O Chiu O et O al O [ O 9 O ] O . O Alternatively O , O tangential O insertion O of O a O trocar O through O the O abdominal O wall O might O be O effective O in O reducing O the O size O of O fascial O defects O . O Moreover O , O recent O publications O have O demonstrated O that O radially O expanding O type O trocars O could O be O useful O to O avoid O the O necessity O of O closing O the O fascial O defect O [ O 10 O ] O . O Symptoms O of O trocar O - O site O herniation O vary O depending O on O the O severity O of O bowel O obstruction O . O Mild O symptoms O such O as O slight O nausea O and O vague O abdominal O pain O , O both O of O which O are O most O frequently O seen O in O the O early O normal O postoperative O course O after O abdominal O surgery O , O could O be O the O first O and O only O complaints O at O the O early O stage O of O this O complication O . O Thus O , O the O diagnosis O may O be O delayed O . O In O our O case O , O mild O abdominal O pain O with O general O malaise O might O have O been O symptoms O related O to O the O early O stage O of O the O onset O . O Abdominal O CT O showing O the O enlarged O duodenum O also O suggested O that O leakage O from O the O duodenal O stump O occurred O due O to O the O obstruction O of O the O distal O bowel O . O Thus O , O severe O complication O might O have O been O avoided O , O if O early O diagnosis O had O been O made O . O Although O the O benefit O of O Roux O - O en O - O Y O is O apparent O [ O 11 O ] O , O the O duodenal O stump O could O be O vulnerable O to O leakage O due O to O increased O intrabowel O pressure O . O Therefore O , O careful O management O of O the O postoperative O course O is O warranted O , O especially O after O procedures O involving O division O of O the O bowel O such O as O LADG O . O Moreover O , O special O attention O should O be O paid O in O patients B with O risk O factors O for O port O site O hernia O such O as O obesity O , O aggressive O manipulation O through O the O port O sites O , O and O prolonged O surgery O . O Conclusion O Port O - O site O herniation O is O a O potentially O dangerous O complication O after O laparoscopic O procedures O . O Careful O management O of O the O postoperative O course O is O recommended O especially O for O patients B with O risk O factors O such O as O obesity O and O extensive O manipulation O of O the O trocar O during O prolonged O surgical O duration O .

O Principal O - O component O analyses O did O not O improve O the O ability O to O identify O chromosomal O regions O of O co O - O localized O gene O expressions O . O Background O There O is O a O breadth O of O information O being O generated O by O the O Human B Genome O Project O and O the O interpretation O of O these O data O has O been O a O major O area O of O research O . O For O simple O Mendelian O disorders O , O the O identification O of O genetic O effects O is O fairly O straightforward O due O to O understanding O the O biology O that O drives O these O disorders O . O However O , O for O complex O oligogenic O or O polygenic O disorders O , O understanding O all O the O interconnections O between O genes O influencing O a O trait O is O a O difficult O task O because O the O understanding O of O the O biology O of O many O of O these O disorders O is O still O evolving O .

O In O an O effort O to O dissect O some O of O these O complexities O , O we O performed O linkage O analysis O of O gene O expression O transcripts O of O members O of O Centre O d O ' O Etude O du O Polymorphisme O Humain O ( O CEPH O ) O Utah O families O to O determine O the O heritability O of O transcripts O and O the O evidence O for O regulatory O quantitative O trait O loci O ( O QTLs O ) O and O we O performed O pairwise O bivariate O linkage O analysis O and O principal O - O component O analysis O ( O PCA O ) O for O data O - O reduction O to O evaluate O the O evidence O for O shared O genetic O effects O .

O For O transcripts O with O co O - O localized O QTLs O , O we O performed O bivariate O linkage O analysis O to O identify O shared O genetic O effects O .

O Chromosome O 13q34 O region O We O performed O analysis O in O an O additional O chromosome O region O of O co O - O localized O transcripts O , O 13q34 O region O , O and O noted O similar O results O . O Using O univariate O analysis O , O 12 O transcripts O co O - O localized O in O this O region O ; O and O bivariate O analysis O revealed O an O intricate O network O of O correlated O traits O ( O Table O 2 O and O Figure O 2 O ) O . O Using O PCA O , O we O obtained O five O factors O , O three O of O them O with O significant O heritability O . O Similar O to O our O previous O findings O on O chomosome O 4 O , O PCA O factors O did O not O improve O the O magnitude O of O the O LOD O scores O when O compared O to O univariate O analysis O . O Discussion O In O this O study O , O we O identified O co O - O localized O QTLs O of O individual O transcripts O and O compared O the O univariate O and O bivariate O linkage O results O using O single O transcripts O to O those O using O factors O obtained O from O PCA O . O By O using O factors O that O accounted O for O the O variance O of O multiple O transcripts O with O co O - O localized O QTLs O , O we O attempted O to O reduce O the O number O of O linkage O analyses O performed O as O well O as O possibly O identifying O previously O unknown O patterns O of O associated O gene O expression O profiles O . O The O PCA O did O in O fact O reduce O the O number O of O linkage O analyses O performed O , O but O it O did O not O improve O the O magnitude O of O signals O in O the O target O QTLs O as O compared O with O univariate O or O bivariate O analyses O . O In O fact O , O in O at O least O one O case O , O PCA O was O unable O to O detect O a O linkage O signal O for O the O main O gene O transcript O loading O in O the O factor O ( O Table O 1 O , O Group O 1 O , O Factor O 2 O ) O . O We O also O performed O pairwise O bivariate O genetic O analysis O on O those O transcripts O that O co O - O localized O to O the O same O genomic O region O , O presumably O because O this O area O of O the O genome O harbored O genes O involved O in O the O regulation O of O these O transcripts O [ O 2 O ] O . O We O detected O significant O genetic O correlation O of O these O co O - O localized O transcripts O , O indicating O potential O gene O networks O operating O in O these O regions O . O However O , O in O most O cases O , O bivariate O linkage O analysis O did O not O improve O the O magnitude O of O the O LOD O score O compared O to O univariate O analysis O . O Most O traits O were O highly O correlated O ( O rho O G O > O 0 O . O 60 O ) O , O and O therefore O they O may O provide O redundant O information O that O may O reduce O the O power O for O detection O of O the O bivariate O signal O [ O 8 O ] O . O In O addition O , O because O rho O G O is O a O test O of O the O overall O additive O genetic O correlation O among O two O traits O and O not O the O QTL O - O specific O pleiotropy O , O it O is O possible O that O the O co O - O localized O linkage O signals O are O not O in O fact O genetically O correlated O . O Further O analysis O is O required O to O address O these O issues O . O The O chromosome O regions O selected O for O detailed O analyses O were O arbitrarily O chosen O as O we O identified O multiple O other O regions O with O co O - O localized O linkage O of O gene O expressions O . O The O results O from O our O univariate O genome O scan O differ O markedly O from O those O reported O by O Morley O et O al O . O [ O 2 O ] O because O we O included O a O smaller O sample O of O individuals O so O that O adjustment O for O covariate O effects O of O age O could O be O made O . O Our O analysis O strategy O also O adjusted O for O the O effects O of O age O and O sex O , O which O could O also O add O to O the O observed O differences O [ O 13 O ] O . O Finally O , O our O definition O of O genome O window O size O for O co O - O localized O gene O expressions O was O twice O larger O than O the O one O described O in O the O study O of O Morley O et O al O .

O Introduction O Selective O serotonin O ( O 5 O - O HT O ; O 5 O - O hydroxytryptamine O ) O reuptake O inhibitors O ( O SSRIs O ) O have O emerged O as O a O major O therapeutic O advance O in O psychopharmacology O . O SSRIs O are O the O treatment O of O choice O for O many O indications O , O including O major O depressive O disorder O , O dysthymia O , O panic O disorder O , O obsessive O - O compulsive O disorder O , O eating O disorders O , O and O premenstrual O dysphoric O disorder O . O In O contrast O , O it O is O well O known O that O their O pharmacology O is O quite O heterogeneous O , O although O all O of O them O block O 5 O - O HT O transporters O , O thus O increasing O 5 O - O HT O levels O throughout O the O central O nervous O system O ( O CNS O ) O [ O 1 O ] O - O [ O 9 O ] O . O Accumulating O evidence O suggests O that O sigma O - O 1 O receptors O , O which O are O intracellular O endoplasmic O reticulum O ( O ER O ) O proteins O , O are O involved O in O both O the O neuroplasticity O and O pathophysiology O of O neuropsychiatric O diseases O such O as O major O depressive O disorder O , O anxiety O , O schizophrenia O , O and O Alzheimer O ' O s O disease O [ O 10 O ] O - O [ O 18 O ] O . O Previously O , O we O reported O that O some O SSRIs O possess O high O to O moderate O affinities O for O sigma O - O 1 O receptors O in O the O rat B brain O . O The O rank O order O of O SSRIs O affinities O for O sigma O - O 1 O receptors O is O fluvoxamine O ( O Ki O = O 36 O nM O ) O > O sertraline O ( O Ki O = O 57 O nM O ) O > O > O paroxetine O ( O Ki O = O 1893 O nM O ) O [ O 19 O ] O . O Recently O , O we O reported O that O fluvoxamine O , O but O not O paroxetine O , O significantly O ameliorated O cognitive O deficits O in O mice B after O repeated O phencyclidine O administration O , O and O that O the O effects O of O fluvoxamine O were O antagonized O by O co O - O administration O of O the O selective O sigma O - O 1 O receptor O antagonist O NE O - O 100 O [ O 20 O ] O , O suggesting O that O sigma O - O 1 O receptors O are O involved O in O the O mechanism O of O action O of O fluvoxamine O [ O 9 O ] O . O Interestingly O , O it O has O been O demonstrated O that O sigma O - O 1 O receptor O agonists O including O fluvoxamine O could O potentiate O nerve O growth O factor O ( O NGF O ) O - O induced O neurite O outgrowth O in O PC12 O cells O , O and O that O NE O - O 100 O blocked O the O potentiation O by O sigma O - O 1 O receptor O agonists O , O suggesting O sigma O - O 1 O receptors O are O involved O in O neuroplasticity O [ O 21 O ] O . O However O , O the O precise O cellular O mechanisms O underlying O the O potentiation O by O sigma O - O 1 O receptor O agonists O are O not O fully O understood O [ O 13 O ] O , O [ O 21 O ] O . O It O is O therefore O of O great O interest O to O study O the O precise O cellular O mechanisms O underlying O the O enhancement O by O fluvoxamine O on O NGF O - O induced O neurite O sprouting O in O PC12 O cells O . O In O the O present O study O , O we O examined O the O effects O of O three O SSRIs O ( O fluvoxamine O , O sertraline O , O paroxetine O ) O , O as O well O as O the O effects O of O a O sigma O - O 1 O receptor O agonist O ( O 4 O - O phenyl O - O 1 O - O ( O 4 O - O phenylbutyl O ) O piperidine O ( O PPBP O ) O , O dehydroepiandrostero O - O sulphate O ( O DHEA O ) O - O sulfate O ) O [ O 9 O ] O , O [ O 22 O ] O - O [ O 28 O ] O and O the O selective O sigma O - O 1 O receptor O agonist O SA4503 O [ O 29 O ] O , O [ O 30 O ] O , O on O NGF O - O induced O neurite O outgrowth O in O PC12 O cells O . O Furthermore O , O it O is O also O known O that O sigma O - O 1 O receptors O have O been O shown O to O interact O with O IP3 O receptors O ( O 17 O , O 18 O ) O . O Therefore O , O we O examined O the O effects O of O NE O - O 100 O and O xestospongin O C O ( O a O selective O inositol O 1 O , O 4 O , O 5 O - O triphosphate O ( O IP3 O ) O receptor O antagonist O ) O [ O 31 O ] O in O order O to O investigate O the O roles O of O sigma O - O 1 O receptors O and O IP3 O receptors O in O the O mechanisms O underlying O the O enhancement O of O NGF O - O induced O neurite O outgrowth O by O SA4503 O . O Moreover O , O we O examined O the O effects O of O specific O inhibitors O of O several O cellular O signaling O targets O on O the O enhancement O of O NGF O - O induced O neurite O outgrowth O by O SA4503 O , O since O several O signal O transduction O molecules O have O been O implicated O in O NGF O - O induced O neurite O outgrowth O [ O 32 O ] O .

O In O contrast O , O these O inhibitors O alone O did O not O alter O NGF O - O induced O neurite O outgrowth O in O PC12 O cells O ( O Figure O 7 O ) O . O Discussion O In O the O present O study O , O we O found O that O fluvoxamine O ( O but O not O sertraline O or O paroxetine O ) O and O the O sigma O - O 1 O receptor O agonists O ( O SA4503 O , O PPBP O , O DHEA O - O sulfate O ) O could O potentiate O NGF O - O induced O neurite O outgrowth O in O PC12 O cells O , O and O that O the O effects O of O these O drugs O were O blocked O by O co O - O incubation O with O the O selective O sigma O - O 1 O receptor O antagonist O NE O - O 100 O . O These O findings O suggest O that O agonism O at O sigma O - O 1 O receptors O for O these O drugs O is O involved O in O the O mechanisms O underlying O the O drugs O ' O potentiation O of O NGF O - O induced O neurite O outgrowth O . O As O shown O in O Figure O 1 O , O NGF O increased O the O number O of O cells O with O neurite O outgrowth O in O PC12 O , O in O a O concentration O dependent O manner O . O To O examine O whether O or O not O the O NGF O levels O are O altered O by O incubation O with O sigma O - O 1 O receptor O agonists O , O we O measured O the O levels O of O NGF O in O PC12 O cells O with O or O without O sigma O - O 1 O receptor O agonist O SA4503 O . O No O differences O of O NGF O levels O were O shown O in O the O between O control O group O and O SA4503 O - O treated O group O ( O data O not O shown O ) O . O It O is O , O therefore O , O unlikely O that O the O potentaition O of O NGF O - O induced O neurite O outgrowth O by O sigma O - O 1 O receptor O agonists O might O be O due O to O increased O levels O of O NGF O . O Unlike O fluvoxamine O , O sertraline O , O which O has O a O moderate O affinity O for O sigma O - O 1 O receptors O , O did O not O alter O NGF O - O induced O neurite O outgrowth O . O The O reasons O underlying O this O discrepancy O between O these O two O SSRIs O are O currently O unclear O . O One O possibility O may O involve O the O difference O in O pharmacological O actions O ( O agonist O vs O . O antagonist O ) O between O these O SSRIs O at O sigma O - O 1 O receptors O . O Interestingly O , O we O recently O found O that O , O in O a O novel O object O recognition O test O , O phencyclidine O - O induced O cognitive O deficits O could O be O significantly O improved O by O subsequent O subchronic O ( O 14 O days O ) O administration O of O fluvoxamine O , O but O not O of O sertraline O , O suggesting O that O sigma O - O 1 O receptor O agonism O is O involved O in O fluvoxamine O ' O s O mechanism O of O action O [ O 9 O ] O , O Ishima O et O al O . O , O submitted O . O Taken O together O , O these O findings O suggest O that O fluvoxamine O and O sertraline O may O function O as O an O agonist O and O an O antagonist O at O sigma O - O 1 O receptors O , O respectively O , O although O further O study O is O necessary O . O Another O possibility O may O be O that O other O pharmacological O activities O of O sertraline O mask O the O effects O of O sigma O - O 1 O receptor O agonism O . O In O this O study O , O we O also O found O that O high O concentration O ( O 10 O micro O M O ) O of O paroxetine O and O sertraline O , O but O not O fluvoxamine O , O showed O cytotoxicity O in O PC12 O cells O , O suggesting O that O fluvoxamine O may O be O a O safe O drug O than O paroxetine O and O sertraline O . O Sigma O - O 1 O receptors O have O been O shown O to O affect O intracellular O Ca2 O + O signaling O , O although O the O precise O molecular O and O cellular O mechanisms O underlying O this O effect O are O unknown O . O Sigma O - O 1 O receptors O bind O to O IP3 O receptors O in O ER O , O and O sigma O - O 1 O receptors O regulate O Ca2 O + O release O from O intracellular O Ca2 O + O storage O sites O [ O 12 O ] O . O Very O recently O , O Hayashi O and O Su O [ O 17 O ] O reported O that O sigma O - O 1 O receptors O function O as O novel O ligand O - O operated O chaperones O that O specifically O target O mitochondrion O - O associated O ER O membrane O . O Furthermore O , O sigma O - O 1 O receptors O form O Ca2 O + O - O sensitive O chaperone O machinery O with O another O chaperone O , O BiP O , O and O prolong O Ca2 O + O signaling O from O ER O into O mitochondria O by O stabilizing O IP3 O receptors O at O mitochondrion O - O associated O ER O membrane O [ O 17 O ] O . O In O this O study O , O we O found O that O the O IP3 O receptor O antagonist O xestospongin O C O significantly O blocked O the O potentiation O of O NGF O - O induced O neurite O outgrowth O by O SA4503 O , O suggesting O the O role O of O IP3 O receptors O on O sigma O - O 1 O receptor O - O mediated O potentiation O of O NGF O - O induced O neurite O outgrowth O . O Therefore O , O it O is O likely O that O stimulation O at O sigma O - O 1 O receptors O by O sigma O - O 1 O receptor O agonists O and O subsequent O interaction O with O IP3 O receptors O are O involved O in O the O mechanism O underlying O the O potentiation O of O NGF O - O induced O neurite O outgrowth O by O sigma O - O 1 O receptor O agonists O . O NGF O binds O to O the O high O - O affinity O tyrosine O receptor O TrkA O , O initiating O several O signaling O pathways O affecting O both O morphological O and O transcriptional O targets O [ O 32 O ] O , O [ O 36 O ] O , O [ O 37 O ] O . O The O signaling O molecules O , O including O PLC O - O gamma O , O PI3K O , O p38 O MAPK O , O and O JNK O , O are O activated O upon O the O addition O of O NGF O [ O 38 O ] O . O PLC O - O gamma O catalyzes O the O hydrolysis O of O phosphatidylinositol O - O 4 O , O 5 O - O bisphosphate O ( O PIP2 O ) O to O diacylglycerol O ( O DAG O ) O and O inositol O triphosphate O ( O IP3 O ) O . O DAG O activates O protein O kinase O C O , O and O IP3 O promotes O transient O release O of O Ca2 O + O from O the O ER O [ O 39 O ] O . O The O pathway O via O PLC O - O gamma O is O responsible O for O NGF O - O induced O cell O differentiation O [ O 40 O ] O and O neurite O outgrowth O [ O 41 O ] O . O Furthermore O , O stimulation O of O PI3K O is O reported O to O be O involved O in O the O promotion O of O neurite O outgrowth O in O PC12 O cells O [ O 42 O ] O . O In O this O study O , O we O found O that O the O PLC O - O gamma O inhibitor O U73122 O and O the O PI3K O inhibitor O LY294002 O significantly O blocked O the O potentiation O of O NGF O - O induced O neurite O outgrowth O by O SA4503 O . O Moreover O , O we O found O that O both O the O p38MAPK O inhibitor O SB203580 O and O the O JNK O inhibitor O SP600125 O significantly O blocked O the O potentiation O of O NGF O - O induced O neurite O outgrowth O by O SA4503 O . O In O addition O , O it O is O also O interesting O that O neurite O outgrowth O induced O by O low O concentration O ( O 2 O . O 5 O ng O / O ml O ) O of O NGF O was O not O blocked O by O these O inihibitors O , O consistent O with O a O previous O report O [ O 43 O ] O , O [ O 44 O ] O , O suggesting O the O existence O of O novel O pathway O ( O s O ) O for O NGF O - O induced O neurite O outgrowth O . O These O findings O suggest O that O the O PLC O - O gamma O , O PI3K O , O p38MAPK O , O and O JNK O signaling O pathways O are O involved O in O the O potentiation O of O NGF O - O induced O neurite O outgrowth O by O sigma O - O 1 O receptor O agonists O ( O Figure O 8 O ) O . O In O addition O , O we O found O that O the O specific O inhibitors O for O the O Raf O / O Ras O / O MEK O / O MAPK O pathways O significantly O blocked O the O potentiation O of O NGF O - O induced O neurite O outgrowth O by O SA4503 O , O suggesting O that O these O pathways O are O involved O in O the O potentiation O of O NGF O - O induced O neurite O outgrowth O by O sigma O - O 1 O receptor O agonists O ( O Figure O 8 O ) O . O Our O recent O positron O emission O tomography O ( O PET O ) O study O demonstrated O that O , O after O a O single O oral O administration O , O fluvoxamine O bound O to O sigma O - O 1 O receptors O in O the O living O human B brain O [ O 45 O ] O . O This O finding O suggests O that O sigma O - O 1 O receptors O are O involved O in O the O mechanism O of O action O of O fluvoxamine O in O the O human B brain O [ O 45 O ] O . O Taken O together O , O the O past O and O present O findings O suggest O that O , O unlike O paroxetine O and O sertraline O , O the O SSRI O fluvoxamine O , O with O its O sigma O - O 1 O receptor O agonistic O activity O , O might O be O a O unique O therapeutic O drug O for O neuropsychiatric O diseases O . O In O conclusion O , O the O present O results O suggest O that O , O as O a O sigma O - O 1 O receptor O agonist O , O fluvoxamine O could O potentiate O the O NGF O - O induced O neurite O outgrowth O in O PC12 O cells O . O Furthermore O , O it O is O likely O that O interaction O with O IP3 O receptors O and O several O subsequent O signaling O molecules O are O involved O in O the O mechanism O underlying O the O pharmacological O action O of O sigma O - O 1 O receptor O agonists O . O Therefore O , O it O is O likely O that O sigma O - O 1 O receptor O agonists O such O as O fluvoxamine O and O DHEA O - O sulfate O , O which O are O available O around O the O world O , O would O be O unique O therapeutic O drugs O for O neuropsychiatric O diseases O . O A O novel O , O non O - O invasive O , O online O - O monitoring O , O versatile O and O easy O plant O - O based O probe O for O measuring O leaf O water O status O Abstract O A O high O - O precision O pressure O probe O is O described O which O allows O non O - O invasive O online O - O monitoring O of O the O water O relations O of O intact O leaves O . O Real O - O time O recording O of O the O leaf O water O status O occurred O by O data O transfer O to O an O Internet O server O . O The O leaf O patch O clamp O pressure O probe O measures O the O attenuated O pressure O , O Pp O , O of O a O leaf O patch O in O response O to O a O constant O clamp O pressure O , O Pclamp O . O Pp O is O sensed O by O a O miniaturized O silicone O pressure O sensor O integrated O into O the O device O . O The O magnitude O of O Pp O is O dictated O by O the O transfer O function O of O the O leaf O , O Tf O , O which O is O a O function O of O leaf O patch O volume O and O ultimately O of O cell O turgor O pressure O , O Pc O , O as O shown O theoretically O . O The O power O function O Tf O = O f O ( O Pc O ) O theoretically O derived O was O experimentally O confirmed O by O concomitant O Pp O and O Pc O measurements O on O intact O leaflets O of O the O liana O Tetrastigma B voinierianum I under O greenhouse O conditions O . O Simultaneous O Pp O recordings O on O leaflets O up O to O 10 O m O height O above O ground O demonstrated O that O changes O in O Tf O induced O by O Pc O changes O due O to O changes O of O microclimate O and O / O or O of O the O irrigation O regime O were O sensitively O reflected O in O corresponding O changes O of O Pp O . O Analysis O of O the O data O show O that O transpirational O water O loss O during O the O morning O hours O was O associated O with O a O transient O rise O in O turgor O pressure O gradients O within O the O leaflets O . O Subsequent O recovery O of O turgescence O during O the O afternoon O was O much O faster O than O the O preceding O transpiration O - O induced O water O loss O if O the O plants O were O well O irrigated O . O Our O data O show O the O enormous O potential O of O the O leaf O patch O clamp O pressure O probe O for O leaf O water O studies O including O unravelling O of O the O hydraulic O communication O between O neighbouring O leaves O and O over O long O distances O within O tall O plants O ( O trees O ) O . O Introduction O Optimum O water O supply O , O particularly O at O peak O needs O of O the O plants O , O is O an O important O issue O for O greenhouse O and O field O vegetable O production O . O In O a O greenhouse O on O a O sunny O day O , O evaporation O and O transpiration O ( O so O - O called O evapotranspiration O ) O can O occur O so O rapidly O that O water O loss O can O cause O plant O damage O before O wilting O symptoms O are O visible O . O Even O at O lower O temperatures O the O restricted O rooting O in O greenhouses O leads O frequently O to O plant O water O deficiency O . O Thus O , O no O matter O how O slight O , O drought O stress O will O result O in O a O significant O reduction O in O growth O and O , O in O turn O , O of O harvest O yield O . O On O the O other O hand O , O over O - O irrigation O must O be O avoided O and O the O appropriate O method O of O watering O must O be O selected O because O wet O soils O and O permanent O moisture O on O plant O organs O promote O the O incidence O of O root O mould O , O grey O mould O ( O Botrytis O blight O ) O , O formation O of O leaf O oedema O , O and O other O plant O diseases O ( O Sherf O and O MacNab O , O 1986 O ) O . O Conservation O of O water O is O another O important O issue O in O semi O - O arid O and O arid O regions O where O water O is O scarce O . O The O advent O of O ( O subsurface O ) O drip O irrigation O has O considerably O reduced O water O consumption O of O agricultural O , O horticultural O , O and O greenhouse O crops O , O but O has O also O highlighted O the O need O for O sensors O monitoring O water O deficiency O of O plants O directly O and O online O ( O Jones O , O 2004 O ) O . O In O plant O physiology O and O agriculture O the O pressure O bomb O technique O pioneered O by O Scholander O et O al O . O ( O 1965 O ) O is O a O widely O accepted O reference O technique O for O measuring O leaf O water O status O . O However O , O the O method O is O massively O invasive O , O slow O , O labour O - O intensive O ( O and O therefore O expensive O ) O , O unsuitable O for O automation O , O and O gives O only O spot O measurements O . O Furthermore O , O interpretation O of O the O data O is O still O a O matter O of O debate O ( O Zimmermann O U O et O al O . O , O 2004 O ; O Zimmermann O D O et O al O . O , O 2007 O ) O . O Leaf O thickness O is O also O sometimes O used O as O an O indicator O for O water O stress O ( O Burquez O , O 1987 O ; O McBurney O , O 1992 O ; O Malone O , O 1993 O ) O . O Leaf O thickness O monitoring O devices O are O commercially O available O . O They O are O non O - O invasive O and O suitable O for O online O measurements O , O but O have O the O disadvantage O that O changes O in O water O status O are O frequently O not O reflected O sensitively O in O changes O of O leaf O thickness O . O The O pressure O probe O technique O pioneered O by O Zimmermann O , O Tomos O , O and O others O ( O Zimmermann O et O al O . O , O 1969 O , O 2004 O ; O Tomos O , O 1988 O ; O Balling O and O Zimmermann O , O 1990 O ) O , O on O the O other O hand O , O is O a O well O established O technology O for O measuring O turgor O and O xylem O pressure O on O the O levels O of O individual O cells O and O xylem O vessels O , O respectively O . O This O technique O is O not O suitable O for O automation O . O Moreover O , O the O probe O technique O requires O rather O sophisticated O equipment O and O a O high O level O of O technical O skill O . O These O disadvantages O are O also O shared O by O the O ball O tonometry O , O a O method O which O allows O non O - O invasive O monitoring O of O cell O turgor O pressure O by O application O of O an O external O pressure O ( O Lintilhac O et O al O . O , O 2000 O ; O Geitmann O , O 2006 O ) O . O Other O water O stress O monitoring O devices O are O described O in O the O literature O , O but O all O of O them O have O various O disadvantages O which O prevented O their O implementation O for O leaf O water O status O measurements O in O greenhouses O or O in O the O field O ( O see O , O for O example O , O the O review O article O of O Jones O , O 2004 O , O and O also O Grant O et O al O . O , O 2007 O ) O . O In O this O communication O a O novel O , O non O - O invasive O , O online O - O monitoring O plant O - O based O probe O is O described O that O meets O the O demands O of O controlling O horticultural O and O agricultural O water O applications O . O The O probe O is O characterized O by O high O precision O , O operating O convenience O , O minimum O costs O , O and O by O automation O suitability O . O Data O can O be O transferred O wireless O to O a O personal O computer O or O to O an O Internet O server O via O a O mobile O phone O network O for O real O - O time O evaluation O and O for O the O automatic O regulation O of O irrigation O . O The O technology O includes O a O miniaturized O silicone O pressure O sensor O integrated O into O a O spring O clamp O that O is O clamped O to O a O patch O of O an O intact O plant O leaf O . O The O patch O clamp O pressure O probe O measures O the O attenuated O pressure O response O of O the O leaf O patch O upon O the O application O of O a O constant O , O clamped O pressure O . O The O attenuation O of O the O applied O pressure O depends O on O the O transfer O function O of O the O leaf O . O The O magnitude O of O the O transfer O function O depends O on O two O terms O , O a O turgor O pressure O - O independent O term O ( O related O to O the O compression O of O the O cuticle O , O cell O walls O , O and O other O structural O elements O ) O and O a O turgor O pressure O - O dependent O term O . O Theory O shows O that O the O turgor O pressure O - O dependent O part O of O the O transfer O function O Tf O is O a O power O function O of O the O cell O turgor O pressure O , O Pc O , O and O predicts O that O Tf O assumes O values O close O to O zero O if O Pc O is O high O and O , O vice O versa O , O values O close O to O unity O if O Pc O is O low O . O This O could O be O verified O by O combined O turgor O pressure O probe O and O leaf O patch O clamp O pressure O probe O measurements O on O leaflets O of O the O liana O Tetrastigma B voinierianum I . O The O 10 O - O m O tall O liana O growing O in O a O tropical O greenhouse O was O selected O for O the O first O studies O because O a O comprehensive O data O set O about O diurnal O changes O in O xylem O and O turgor O pressure O gradients O under O various O environmental O conditions O existed O for O this O greenhouse O plant O ( O Benkert O et O al O . O , O 1995 O ; O Th O u O rmer O et O al O . O , O 1999 O ; O see O also O Zimmermann O et O al O . O , O 2004 O ) O . O Measurements O of O diurnal O changes O of O the O patch O clamp O pressure O performed O here O yielded O results O which O were O consistent O with O the O previous O pressure O probe O work O on O the O liana O . O The O data O also O demonstrated O that O changes O in O the O irrigation O regime O and O in O microclimate O can O be O sensed O by O this O novel O probe O very O sensitively O and O that O use O of O several O probes O allowed O the O study O of O the O diurnal O water O transport O at O multiple O scales O from O single O leaves O to O the O whole O organism O ( O Meinzer O et O al O . O , O 2001 O ) O . O This O can O be O done O without O knowledge O of O the O turgor O pressure O because O the O transfer O function O is O a O direct O measure O of O leaf O water O status O . O Materials O and O methods O Plant O material O Experiments O were O performed O on O two O specimens O of O the O liana O Tetrastigma B voinierianum I , O growing O in O the O c O . O 12 O m O tall O tropical O greenhouse O of O the O University O of O Salzburg O , O Austria O . O The O ground O ascended O by O about O 5 O m O towards O the O backstage O of O the O greenhouse O . O The O height O of O the O plant O in O this O area O was O about O 4 O .

O However O , O the O stem O and O the O branches O of O the O two O plants O were O considerably O longer O , O because O the O plants O had O grown O vertically O upwards O and O then O part O of O the O way O downwards O . O First O measurements O were O performed O during O the O last O week O of O May O , O 2007 O . O This O week O was O very O sunny O and O warm O . O Experiments O were O repeated O during O the O last O week O of O August O and O the O first O week O of O September O , O 2007 O . O At O this O time O of O the O year O the O weather O conditions O were O quite O poor O . O The O weeks O were O rainy O , O sunshine O occurred O only O occasionally O . O On O average O , O the O sky O was O very O cloudy O . O Due O to O the O variable O weather O conditions O the O ambient O temperature O , O T O , O in O the O greenhouse O usually O varied O between O 19 O degrees O C O and O 27 O degrees O C O . O By O contrast O , O during O the O hot O week O in O May O temperatures O at O the O top O of O the O plants O could O reach O up O to O 44 O degrees O C O . O The O greenhouse O was O illuminated O between O 07 O . O 30 O h O and O 19 O . O 00 O h O ( O CET O = O Central O European O Time O ) O . O During O the O day O - O time O , O the O artificial O illumination O was O switched O off O automatically O once O the O natural O irradiance O exceeded O about O 45 O mu O mol O photons O m O - O 2 O s O - O 1 O at O ground O level O . O At O full O sunshine O , O the O light O intensity O was O limited O by O automatically O operating O blinds O . O The O relative O humidity O ( O r O . O h O . O ) O of O the O air O was O regulated O by O overhead O misters O . O Despite O attempts O to O keep O the O r O . O h O . O above O 60 O - O 70 O % O large O axial O r O . O h O . O gradients O along O the O stem O of O the O liana O were O observed O during O sunny O days O ( O see O below O ) O . O The O ambient O temperature O and O relative O humidity O at O the O measuring O sites O were O determined O by O using O thermistors O ( O Tinytag O ; O RS O Components O GmbH O , O M O o O rfelden O - O Walldorf O , O Germany O ) O . O Leaf O patch O clamp O pressure O probe O and O data O acquisition O The O pressure O sensor O chip O allows O pressure O measurements O up O to O 100 O kPa O . O The O sensor O consists O of O a O miniature O piezoresistive O Wheatstone O bridge O . O The O sensors O used O in O this O work O were O purchased O from O the O company O ' O Raumedic O ' O ( O Helmbrechts O , O Germany O ) O and O from O the O company O ' O Keller O ' O ( O AG O , O Druckmesstechnik O ; O Winterthur O , O Switzerland O ) O . O However O , O it O has O to O be O pointed O out O that O any O other O miniaturized O pressure O or O force O sensor O could O be O used O . O The O sensor O chip O was O integrated O into O one O of O the O planar O circular O pads O of O a O spring O clamp O shown O schematically O in O Fig O . O 1 O . O The O spring O clamp O consisted O of O two O curved O arms O bridged O by O a O spring O in O the O middle O ( O Wolfcraft O GmbH O ; O microfix O S O ( O B3630Fz60 O ) O , O Kempenich O , O Germany O ) O . O The O clamp O pressure O exerted O by O the O spring O on O the O leaf O , O Pclamp O , O could O be O varied O by O a O stiff O strap O ( O made O of O synthetic O material O ) O spanned O between O the O arms O of O the O spring O clip O at O the O handhold O site O ( O Fig O . O 1 O ) O . O The O length O of O the O strap O and O thus O the O spring O load O acting O on O the O leaflet O between O the O two O pads O could O be O varied O by O regularly O punched O holes O ( O as O in O a O belt O ) O . O Calibration O of O the O sensor O chips O was O performed O by O pressurization O in O a O pressure O chamber O equipped O with O an O integrated O manometer O ( O LEO O 1 O , O Keller O AG O , O Winterthur O , O Switzerland O ) O . O The O readings O of O all O sensors O used O in O this O study O increased O linearly O with O pressure O in O the O range O between O 0 O kPa O and O 100 O kPa O . O The O pressure O sensitivity O of O the O various O sensors O was O found O to O be O almost O identical O for O all O probes O . O Before O use O the O probes O were O also O tested O for O temperature O - O sensitivity O in O an O accessible O climate O chamber O because O it O is O well O - O known O that O silicone O - O embedded O sensors O tend O to O become O temperature O - O sensitive O during O storage O . O Probes O were O subject O to O temperature O regimes O ranging O from O 10 O degrees O C O to O 35 O degrees O C O . O Probes O were O not O used O if O the O temperature O treatment O induced O a O pressure O change O larger O than O 0 O . O 5 O kPa O . O The O signals O of O the O leaf O patch O clamp O pressure O probe O were O transmitted O by O a O telemetry O system O ( O teleBITcom O gmbh O , O Teltow O , O Germany O ) O . O The O operating O distance O between O the O battery O - O powered O wireless O telemetric O transmitter O and O the O receiver O base O station O was O up O to O 400 O m O . O Each O transmitter O read O , O amplified O , O and O converted O the O analogue O signals O of O the O pressure O sensor O into O digitalized O signals O . O The O data O were O sent O together O with O the O transmitter O ID O - O code O every O 90 O s O via O the O ISM O band O of O 433 O MHz O to O the O receiver O base O station O which O logged O and O transferred O the O data O to O a O personal O computer O or O to O a O GPRS O modem O linked O to O an O Internet O server O ( O NTBB O Systemtechnik O GmbH O , O Zeuthen O , O Germany O ) O for O analysis O and O archival O storage O . O For O sensor O calibration O and O data O recording O the O SENBIT O software O ( O teleBITcom O gmbh O , O Teltow O , O Germany O ) O was O used O . O The O software O allowed O communication O with O up O to O 32 O sensors O at O regular O short O intervals O ( O 90 O s O to O 5 O min O ) O . O In O this O study O , O up O to O 10 O sensor O / O transmitter O units O were O installed O at O different O heights O on O the O two O lianas O . O Data O transfer O to O the O Internet O server O operated O without O any O problem O during O the O entire O experimental O period O . O However O , O for O safety O reasons O hard O - O wired O conventional O data O acquisition O was O also O performed O using O dataloggers O ( O Raumedic O , O Helmbrechts O , O Germany O ) O . O The O dataloggers O were O controlled O by O a O computer O program O that O provided O functions O for O data O storage O and O sensor O calibration O . O Data O were O transferred O regularly O from O the O dataloggers O to O a O personal O computer O . O Cell O turgor O pressure O probe O Turgor O pressure O measurements O were O performed O on O leaflets O of O the O 10 O - O m O tall O liana O at O c O . O 0 O . O 2 O m O height O above O the O roots O . O The O construction O and O function O of O the O cell O turgor O pressure O probe O has O been O described O elsewhere O ( O Zimmermann O et O al O . O , O 1969 O , O 2004 O ) O . O Briefly O , O the O microcapillary O was O filled O with O oil O up O to O the O very O tip O and O was O then O inserted O into O the O upper O leaflet O surface O between O the O main O vein O and O the O leaflet O edge O . O Insertion O was O made O under O a O small O overpressure O ( O about O 20 O kPa O ) O achieved O by O appropriate O displacement O of O the O metal O rod O in O the O probe O in O order O to O avoid O tip O clogging O . O Penetration O was O stopped O upon O reaching O the O mesophyll O cell O layer O and O formation O of O a O stable O oil O / O sap O meniscus O within O the O tip O region O of O the O microcapillary O of O the O probe O . O During O the O measurements O it O was O regularly O proved O whether O the O tip O was O clogged O or O not O by O appropriate O displacement O of O the O metal O rod O . O Theoretical O background O The O input O pressure O , O Pin O , O experienced O by O the O cells O in O a O leaf O patch O is O equal O to O the O clamp O pressure O , O Pclamp O , O only O if O the O pressure O signal O is O transferred O lossless O to O the O cells O in O the O leaves O . O However O , O losses O usually O occur O due O to O the O compressibility O and O the O deformability O of O the O silicone O of O the O pressure O sensor O as O well O as O of O the O compressibility O of O the O cuticle O and O other O structural O elements O of O the O leaf O . O Therefore O , O theory O shows O that O only O a O fraction O of O Pclamp O may O arrive O at O the O cells O , O i O . O e O . O that O the O attenuation O factor O , O Fa O = O Pin O / O Pclamp O , O is O smaller O than O unity O . O Fa O depends O on O the O individual O leaf O properties O . O Fa O can O be O assumed O to O be O constant O ( O and O leaf O thickness O changes O are O negligible O ) O if O the O structural O elements O are O completely O pre O - O compressed O by O application O of O an O appropriate O Pclamp O . O If O Pclamp O is O kept O constant O during O the O following O experimental O period O , O Pin O is O constant O and O the O output O pressure O , O Pp O , O is O only O determined O by O the O cell O transfer O function O , O Tf O ( O V O ) O , O where O V O is O the O leaf O patch O volume O . O In O other O words O , O Tf O ( O V O ) O determines O the O fraction O of O Pin O sensed O by O the O probe O . O It O is O dimensionless O and O assumes O values O between O zero O and O unity O : O ( O 1 O ) O Tf O depends O on O the O volume O of O the O leaf O patch O , O V O , O at O constant O ambient O temperature O , O T O : O ( O 2 O ) O delta O V O depends O on O changes O in O cell O turgor O pressure O , O delta O Pc O , O as O follows O : O ( O 3 O ) O where O op O is O the O average O volumetric O elastic O modulus O of O the O clamped O tissue O ( O Philip O , O 1958 O ) O . O op O is O a O very O complex O parameter O and O will O be O dictated O by O the O turgor O pressure O in O the O turgescent O state O . O For O a O first O approximation O it O is O assumed O that O op O increases O linearly O with O Pc O ( O support O for O this O assumption O is O given O by O Zimmermann O and O Steudle O , O 1978 O ; O Zimmermann O and O H O u O sken O , O 1980 O ; O Wendler O et O al O . O , O 1983 O ) O : O ( O 4 O ) O where O a O and O b O are O constants O for O individual O leaf O properties O . O Because O of O the O viscoelastic O properties O of O the O cell O wall O , O the O magnitude O of O the O constants O depends O on O the O duration O of O the O external O pressure O application O ( O Zimmermann O and O H O u O sken O , O 1980 O ) O . O The O constants O are O relatively O large O if O rapid O turgor O pressure O changes O are O induced O ( O e O . O g O . O by O using O the O cell O turgor O pressure O probe O ) O , O whereas O slow O turgor O pressure O changes O ( O e O . O g O . O under O transpirational O conditions O ) O result O in O small O values O . O Combining O equations O 2 O - O 4 O leads O to O equation O 5 O . O ( O 5 O ) O Equation O 5 O can O be O integrated O by O assuming O for O a O first O approximation O that O at O Pc O = O 0 O Tf O = O 1 O and O that O the O internal O osmotic O pressure O of O the O cells O remained O constant O . O After O appropriate O re O - O arrangements O equation O 6 O is O obtained O : O ( O 6 O ) O and O , O respectively O , O if O the O denominator O is O replaced O by O equation O 4 O : O ( O 7 O ) O Introducing O equation O 6 O into O equation O 1 O yields O the O wanted O relationship O between O the O parameters O Pp O and O Pin O : O ( O 8 O ) O Equation O 8 O can O be O verified O experimentally O . O Inspection O of O the O equation O shows O that O the O patch O clamp O pressure O , O Pp O , O is O a O power O function O of O the O turgor O pressure O , O Pc O . O The O exponent O of O the O function O is O equal O to O or O smaller O than O unity O . O If O a O = O 1 O and O b O < O < O Pc O , O equation O 8 O turns O into O Pp O = O b O / O Pc O , O i O . O e O . O both O parameters O are O directly O reciprocally O coupled O with O each O other O . O Thus O Tf O assumes O low O values O if O Pc O is O high O and O , O vice O versa O , O a O value O close O to O unity O if O Pc O is O close O to O zero O . O Using O appropriate O values O for O a O and O b O for O a O given O leaf O ( O see O below O ) O it O can O be O shown O that O below O Pc O = O 100 O kPa O , O Pp O increases O dramatically O . O This O means O that O the O transfer O function O responds O very O sensitively O upon O loss O of O complete O turgor O pressure O . O In O the O derivation O of O equation O 8 O it O was O assumed O that O op O is O temperature O - O independent O . O However O , O temperature O effects O on O cell O elasticity O are O well O - O known O , O although O they O are O not O very O large O in O the O temperature O range O investigated O here O ( O see O , O for O example O , O Petersen O et O al O . O , O 1982 O ; O Niklas O , O 1992 O ; O Hogan O and O Niklas O , O 2004 O ; O Edelmann O et O al O . O , O 2005 O ) O . O Temperature O effects O on O op O cannot O be O excluded O if O different O values O for O the O Pclamp O , O and O , O in O turn O , O for O the O input O pressure O , O Pin O , O are O selected O , O as O well O as O if O significantly O different O values O for O the O constants O a O and O b O are O assumed O for O optimum O fitting O of O the O Pp O = O f O ( O Pc O ) O curves O .

O However O , O Pp O values O measured O at O the O same O height O are O still O comparable O and O give O information O about O the O turgescence O , O i O . O e O . O about O the O water O status O of O the O leaf O cells O . O Results O The O leaf O patch O clamp O pressure O probe O was O clamped O about O 2 O cm O away O from O the O edge O of O a O leaflet O of O the O compound O leaves O . O Leaflets O of O similar O size O ( O 176 O + O / O - O 58 O cm2 O , O n O = O 12 O ) O were O used O . O Inspection O of O the O leaf O patches O after O removal O of O the O probes O under O the O microscope O revealed O no O changes O in O leaflet O appearance O beneath O the O pads O , O even O after O several O weeks O . O Lesions O on O the O leaves O were O never O found O . O Only O occasionally O were O very O slight O impressions O of O the O pads O on O the O leaflet O surface O observed O . O Clamping O of O the O leaves O could O be O performed O at O any O time O of O the O day O . O Clamp O pressures O , O Pclamp O , O applied O to O the O leaves O were O of O the O order O of O 80 O - O 200 O kPa O . O The O optimum O value O for O Pclamp O of O a O given O leaf O has O to O be O found O empirically O . O Experience O shows O that O Pclamp O values O could O be O considered O as O optimal O if O the O output O pressure O Pp O assumed O values O between O 10 O kPa O and O 25 O kPa O upon O clamping O in O the O early O morning O ( O when O turgor O pressure O was O high O ) O or O between O 50 O kPa O and O 70 O kPa O upon O clamping O around O noon O or O towards O early O afternoon O ( O when O turgor O pressure O was O usually O low O ) O . O The O magnitude O of O Pp O depended O on O the O compressibility O and O deformability O properties O of O the O individual O leaves O which O may O vary O considerably O due O to O age O , O morphology O , O leaf O thickness O , O abiotic O factors O etc O . O The O magnitude O of O Pclamp O had O no O effect O on O the O diurnal O profiles O of O Pp O , O in O response O to O changes O in O microclimate O and O / O or O changes O in O the O irrigation O regime O . O Probes O clamped O on O the O same O leaflet O or O nearby O leaflets O of O leaves O responded O almost O identically O upon O temporary O changes O in O transpiration O and O / O or O water O supply O even O if O the O Pclamp O values O were O different O due O to O different O leaf O thickness O as O well O as O local O compressibility O and O deformability O properties O ( O data O not O shown O ) O . O This O was O found O over O the O entire O height O of O the O plants O .

O Non O - O uniform O contact O resulted O in O a O reduced O pressure O response O of O the O probe O ( O data O not O shown O ) O . O Thus O , O in O order O to O obtain O maximum O resolution O of O microclimate O - O induced O and O / O or O plant O - O based O effects O on O the O Pp O values O , O it O was O crucial O that O the O probe O was O placed O on O relatively O smooth O areas O , O i O .

O It O also O turned O out O that O areas O with O lesions O or O covered O with O dust O should O be O avoided O .

O Patch O clamp O pressure O versus O cell O turgor O pressure O measurements O The O leaf O patch O clamp O pressure O probe O measures O the O pressure O transfer O function O of O a O defined O leaflet O area O . O The O above O theoretical O considerations O have O shown O that O the O transfer O function O is O mainly O determined O by O turgor O pressure O provided O that O the O structural O elements O do O not O contribute O or O constantly O contribute O to O the O pressure O signal O transfer O .

O Measurements O were O performed O after O several O days O of O irrigation O .

O For O this O reason O , O measurements O with O the O Scholander O pressure O chamber O were O not O very O reliable O . O It O was O extremely O difficult O to O determine O exactly O the O balancing O pressure O at O which O water O appears O at O the O cut O end O of O the O petiole O of O the O leaf O .

O Changes O in O Pc O after O sunrise O preceded O changes O in O Pp O , O most O likely O due O to O the O different O measuring O sites O on O the O leaflets O . O After O the O onset O of O transpiration O the O loss O of O turgor O pressure O of O cells O located O at O the O periphery O of O the O leaflets O ( O where O Pp O is O recorded O ) O is O apparently O immediately O compensated O by O water O shifting O from O the O xylem O and O the O cells O located O close O to O the O main O vein O ( O where O Pc O is O measured O ) O . O Consistent O with O this O explanation O , O towards O the O afternoon O when O all O cells O throughout O the O leaflets O exhibit O low O turgor O pressure O , O the O increase O in O Pc O and O the O decrease O in O Pp O occurred O nearly O concomitantly O .

O Turgor O pressure O measurements O at O 5 O m O height O failed O because O of O abundant O mucilage O in O the O leaflet O tissue O at O this O time O of O the O year O .

O Discussion O The O results O presented O here O demonstrate O that O the O novel O patch O clamp O pressure O probe O is O a O very O sensitive O , O versatile O , O and O easy O - O to O - O handle O plant O - O based O tool O for O online O monitoring O of O the O effects O of O evapotranspiration O and O / O or O of O irrigation O regimes O on O the O water O relations O of O leaves O ( O Figs O 2 O , O 3 O ) O . O The O probe O measures O the O output O signal O upon O application O of O a O constantly O clamped O pressure O , O i O . O e O . O the O pressure O transfer O function O of O leaf O patches O . O Since O the O application O of O the O probe O is O not O restricted O to O special O leaves O , O patch O clamp O pressure O measurements O will O readily O show O which O crop O varieties O can O be O grown O with O the O least O water O for O the O most O yield O . O It O has O also O been O demonstated O here O that O the O plant O - O based O data O can O be O sent O by O small O telemetric O units O connected O to O the O patch O clamp O pressure O probes O to O a O receiver O base O station O which O logs O and O stores O the O data O pending O transfer O to O a O GPRS O modem O linked O to O an O Internet O server O . O The O telemetric O systems O operated O faultlessly O . O This O is O a O very O important O result O because O there O is O agreement O between O scientists O and O growers O ( O Jones O , O 2004 O ) O that O control O of O irrigation O must O be O tied O to O remote O sensing O devices O in O order O to O reduce O manpower O and O to O conserve O water O . O The O patch O clamp O pressure O probe O technique O introduced O here O meets O these O demands O . O A O further O advantage O is O that O the O probe O is O cheap O and O easy O to O handle O . O Some O care O is O required O only O when O clamping O the O leaf O . O Leaves O must O be O clean O and O any O rough O surface O topography O must O be O avoided O . O This O implies O that O the O dimensions O of O the O pads O of O the O spring O clamp O must O be O adjusted O to O the O size O of O the O intercostal O area O since O non O - O uniform O contact O between O leaf O surface O and O pads O lowered O the O output O pressure O signal O . O Experience O collected O with O patch O clamp O pressure O measurements O on O T B . I voinierianum I and O on O preliminary O results O of O other O plants O ( O e O . O g O . O grapevines O , O bananas B , O Eucalyptus O , O and O Arabidopsis O ) O showed O that O a O smooth O intercostal O leaf O area O for O clamping O can O readily O be O found O . O Equally O , O optimum O values O for O the O clamp O pressure O can O also O be O relatively O quickly O selected O empirically O if O the O guidelines O mentioned O above O are O followed O . O For O many O purposes O calibration O of O the O leaf O patch O clamp O pressure O probe O against O the O cell O turgor O pressure O probe O is O not O stringent O . O It O may O be O sufficient O to O know O that O the O transfer O function O assumes O small O values O at O full O turgescence O and O is O nearly O unity O at O low O turgescence O . O However O , O for O scientific O reasons O and O for O the O application O of O the O probe O in O basic O research O , O the O dependency O of O the O transfer O function O on O cell O turgor O pressure O might O be O of O great O interest O . O The O theoretical O considerations O have O demonstrated O that O the O relationship O between O the O transfer O function O and O the O turgor O pressure O can O obviously O be O described O by O equation O 8 O , O i O . O e O . O by O a O power O function O . O Concomitant O measurements O of O turgor O pressure O and O patch O clamp O pressure O have O confirmed O the O theoretical O considerations O ( O Fig O . O 5 O ) O . O Analogous O recordings O of O turgor O pressure O and O patch O clamp O pressure O on O grapevines O , O bananas B , O and O Eucalyptus B trees O also O yielded O results O ( O D O Zimmermann O , O unpublished O results O ) O which O were O consistent O with O the O predictions O of O equation O 8 O . O Patch O clamp O pressure O measurements O allow O , O therefore O , O calculation O of O turgor O pressures O if O the O constants O a O and O b O defined O by O equation O 4 O are O known O . O These O parameters O can O be O obtained O by O numerical O fitting O of O Pp O versus O Pc O curves O . O Online O patch O clamp O pressure O measurements O open O up O new O possibilities O to O unravel O the O hydraulic O communication O among O leaves O , O including O tall O trees O . O It O is O shown O here O that O the O patch O clamp O pressure O can O simultaneously O be O monitored O in O shaded O or O sun O - O exposed O leaflets O at O different O heights O under O greenhouse O conditions O by O using O several O probes O . O It O was O even O possible O to O measure O the O turgor O pressure O at O different O sites O on O the O leaf O . O Therefore O , O water O shifting O between O leaf O cells O via O the O apoplastic O and O symplastic O pathways O can O be O studied O . O Physically O sound O theories O are O available O ( O Molz O and O Ikenberry O , O 1974 O ; O Molz O et O al O . O , O 1979 O ) O , O but O experimental O facts O are O not O available O or O are O mainly O based O on O speculations O ( O Steudle O and O French O , O 1996 O ) O . O The O first O evidence O for O the O dynamics O of O the O hydraulic O communication O between O leaflets O at O different O height O and O within O leaflets O is O given O here O . O Th O u O rmer O et O al O . O ( O 1999 O ) O have O shown O by O using O the O xylem O and O turgor O pressure O probe O that O the O decrease O in O local O xylem O pressure O after O daybreak O from O positive O , O sub O - O atmospheric O or O slightly O above O - O atmospheric O values O to O negative O values O was O associated O with O an O almost O 1 O : O 1 O decrease O in O turgor O pressure O of O the O cells O located O close O to O the O main O vein O of O the O leaflets O ( O see O also O Zimmermann O et O al O . O , O 2004 O ) O . O Similarly O , O in O the O afternoon O , O the O increase O of O xylem O pressure O in O non O - O cavitated O vessels O towards O more O positive O values O correlated O with O a O 1 O : O 1 O increase O in O cell O turgor O pressure O . O Obviously O , O changes O in O transpiration O resulted O in O a O very O rapid O establishment O of O a O new O local O water O equilibrium O state O between O the O xylem O and O the O turgor O pressure O of O the O adjacent O cells O . O The O turgor O pressure O measurements O of O Th O u O rmer O et O al O . O ( O 1999 O ) O were O performed O at O 1 O m O and O 5 O m O height O . O No O significant O differences O in O the O turgor O pressure O values O were O found O over O the O day O . O The O turgor O pressure O measurements O at O 0 O . O 2 O m O height O reported O here O confirmed O the O finding O of O Th O u O rmer O et O al O . O ( O 1999 O ) O that O the O turgor O pressure O in O the O cells O located O near O the O main O vein O dropped O immediately O upon O daybreak O . O However O , O our O patch O clamp O pressure O measurements O at O the O periphery O of O the O leaflets O imply O that O the O turgor O pressure O of O these O cells O apparently O had O a O significantly O delayed O response O upon O the O onset O of O transpiration O . O This O finding O can O be O taken O as O evidence O that O turgor O pressure O gradients O are O temporarily O generated O within O the O leaf O during O the O early O morning O hours O . O This O delay O in O the O response O of O patch O clamp O pressure O after O daybreak O was O c O . O 1 O h O for O leaves O at O the O top O , O but O c O . O 2 O . O 5 O h O for O leaves O at O the O base O . O The O data O suggest O that O with O progression O of O the O day O the O gradients O collapsed O first O at O the O top O of O the O liana O , O where O transpiration O was O high O , O before O it O occurred O in O leaves O further O down O . O During O the O afternoon O hours O the O increase O in O the O turgor O pressure O values O measured O close O to O the O main O vein O coincided O with O the O values O measured O by O the O patch O clamp O pressure O probe O ( O Fig O . O 5 O ) O . O The O unbalanced O osmotic O pressure O throughout O the O leaflets O obviously O favoured O simultaneous O turgor O pressure O regeneration O in O all O leaflet O cells O . O The O process O seemed O to O be O very O similar O to O the O refilling O of O the O cells O of O the O resurrection O plant O Myrothamnus B flabellifolia I with O water O after O desiccation O ( O Wagner O et O al O . O , O 2000 O ) O . O Uniform O radial O refilling O of O cells O with O water O in O this O species O is O also O driven O by O the O unbalanced O osmotic O pressure O throughout O the O tissue O . O As O indicated O by O Fig O . O 4A O and O B O , O restoration O of O full O turgescence O in O T B . I voinierianum I was O faster O than O the O preceding O turgor O pressure O loss O if O the O lianas O were O well O - O watered O . O By O contrast O , O limitations O in O water O supply O resulted O in O the O coincidence O of O the O phases O of O turgor O pressure O loss O and O regeneration O . O Interestingly O , O watering O of O the O lianas O after O non O - O irrigation O seemed O to O lead O preferentially O to O water O shifting O to O the O top O of O the O plant O , O because O , O after O 3 O d O of O irrigation O , O turgor O pressure O regeneration O during O the O afternoon O was O very O fast O again O at O 10 O m O height O ( O Fig O . O 4F O ) O , O but O not O at O 5 O m O height O ( O Fig O . O 4E O ) O . O Rapid O water O movement O to O the O top O is O expected O if O hydrostatic O pressure O , O osmotic O pressure O , O and O / O or O gel O - O based O gradients O throughout O the O vessels O exist O or O are O generated O rapidly O in O the O afternoon O when O cavitation O has O occurred O . O This O was O demonstrated O by O Benkert O et O al O . O ( O 1995 O ) O and O Th O u O rmer O et O al O . O ( O 1999 O ) O by O using O the O xylem O pressure O probe O . O Continuous O xylem O pressure O gradients O during O the O morning O hours O can O also O explain O why O changes O in O Pp O at O lower O heights O were O frequently O found O which O could O not O be O correlated O with O changes O in O local O temperature O or O relative O humidity O . O Water O loss O at O the O top O of O the O plant O induces O a O drop O in O xylem O pressure O which O is O transferred O rapidly O to O the O basal O leaves O where O it O induces O a O temporary O turgor O pressure O loss O that O is O soon O compensated O by O water O uptake O from O the O roots O ( O arrow O in O Fig O . O 2 O ) O . O Even O though O more O work O is O required O , O the O present O study O shows O that O the O leaf O patch O clamp O pressure O probe O is O a O promising O tool O to O elucidate O short O - O and O long O - O distance O water O transport O in O T B .

O Materials O and O Methods O Patients B A O total O of O 223 O patients B with O locally O advanced O non O - O inflammatory O breast O cancer O ( O T3 O - O 4 O and O / O or O N2 O ) O were O randomly O allocated O to O primary O treatment O either O with O epirubicin O 90 O mg O / O m2 O or O paclitaxel O 200 O mg O / O m2 O .

O CHEK2 O Mutant O ' O s O Capability O to O Form O Dimers O To O investigate O whether O the O identified O CHEK2 O mutations O affect O the O ability O of O the O Chk2 O protein O to O form O dimers O , O co O - O transfection O and O immunopresipitation O of O V5 O - O tagged O mutants O and O Xpress O - O tagged O wild O - O type O Chk2 O were O performed O using O CHEK2 O low O - O expressing O U O - O 2 O - O OS O cells O . O As O we O identified O the O previously O characterized O CHEK2 O germline O mutants O variants O Arg117His O ( O n O = O 2 O and O Ile157Thr O ( O n O = O 1 O ) O among O patients B allocated O to O primary O treatment O with O paclitaxel O in O our O ongoing O study O , O these O mutants O were O evaluated O together O with O Arg95Ter O and O Ile364Thr O . O The O results O presented O in O Figure O 2 O show O that O all O Chk2 O variants O carrying O a O point O mutation O were O able O to O form O dimers O with O wild O - O type O Chk2 O , O whereas O the O Arg95Ter O variant O was O not O . O Kinase O Activity O of O CHEK2 O Mutants O To O investigate O whether O the O identified O CHEK2 O mutants O retained O the O wild O - O type O kinase O activity O , O an O in O vitro O Chk2 O kinase O assay O with O respect O to O Chk2 O autophosphorylation O and O Cdc25 O substrate O phosphorylation O was O performed O . O The O U O - O 2 O - O OS O cells O were O preferred O for O this O assay O because O they O were O previously O found O to O express O only O low O levels O of O endogenous O Chk2 O [ O 44 O ] O . O This O was O confirmed O by O us O using O an O antibody O recognizing O endogenous O protein O ( O data O not O shown O ) O . O These O cells O have O previously O been O used O by O other O investigators O to O study O Chk2 O kinase O activity O [ O 44 O ] O , O [ O 45 O ] O , O [ O 46 O ] O . O The O two O mutants O Arg117Gly O and O Ile157Thr O were O previously O tested O for O in O vitro O kinase O activity O [ O 47 O ] O , O but O were O both O included O here O , O together O with O wild O - O type O CHEK2 O as O controls O . O Compared O to O wild O - O type O Chk2 O , O the O Ile157Thr O mutant O retained O wild O - O type O kinase O activity O . O The O mutant O Ile364Thr O showed O partially O reduced O kinase O activity O both O in O term O of O Cdc25 O - O phosphorylation O and O autophosphorylation O ( O Figure O 3 O ) O . O In O contrast O , O the O mutant O Arg117Gly O showed O strongly O reduced O kinase O activity O while O the O Arg95Ter O mutant O was O totally O devoid O of O any O Chk2 O kinase O activity O . O The O activity O recorded O for O Ile157Thr O and O Arg117Gly O was O consistent O with O previously O reported O results O for O these O two O mutants O [ O 47 O ] O . O Notably O , O there O was O an O internal O consistency O with O respect O to O percentage O activity O reduction O comparing O individual O mutants O with O respect O to O autophosphorylation O and O phosphorylation O of O Cdc25 O ( O Figure O 3 O ) O . O Since O enzymatically O active O Chk2 O exists O as O dimers O , O it O was O important O to O determine O the O effect O of O Chk2 O mutants O on O wild O - O type O / O mutant O heterodimer O kinase O activity O . O The O effect O on O Chk2 O kinase O activities O ( O Chk2 O autophosphorylation O and O Cdc25 O substrate O phosphorylation O ) O of O the O individual O mutants O were O therefore O determined O after O co O - O transfection O with O wild O - O type O Chk2 O as O described O in O Materials O and O Methods O . O The O results O from O this O co O - O transfection O - O kinase O assay O ( O Figure O 4 O ) O were O similar O to O those O of O the O single O - O transfection O assay O ( O Figure O 3 O ) O except O in O the O case O of O the O Arg117Gly O mutant O , O which O expressed O a O substantial O kinase O activity O when O complexed O with O wild O - O type O Chk2 O . O This O is O consistent O with O previous O data O indicating O that O the O Arg117Gly O mutant O has O neglectable O kinase O activity O itself O but O dimerizes O efficiently O to O Chk2 O wild O - O type O without O strongly O affecting O the O wild O - O type O Chk2 O activity O . O Hence O , O the O activity O detected O is O probably O caused O by O the O co O - O transfected O and O co O - O precipitated O wild O - O type O protein O . O To O rule O out O the O possibility O that O endogenously O expressed O wild O - O type O Chk2 O contributed O to O observed O Arg117Gly O kinase O activity O shown O in O Figure O 4 O , O we O compared O the O Arg117Gly O variant O activity O in O the O presence O or O absence O of O co O - O transfected O wild O - O type O Chk2 O to O the O activities O of O Arg95Ter O under O the O same O conditions O . O The O Arg95Ter O variant O does O not O form O dimers O with O wild O - O type O Chk2 O . O As O seen O in O Figure O 5 O , O Arg117Gly O , O which O forms O dimers O with O Chk2 O wild O - O type O , O allows O increased O activity O when O co O - O transfected O with O wild O - O type O as O compared O to O the O corresponding O activity O for O the O Arg95Ter O mutant O . O The O fact O that O Arg117Gly O , O when O transfected O alone O , O displays O very O similar O activity O as O Arg95Ter O or O negative O control O ( O background O levels O ) O , O strongly O indicates O that O the O contribution O of O endogenous O Chk2 O , O which O , O similarly O to O exogenously O expressed O wild O - O type O Chk2 O co O - O precipitate O with O Arg117Gly O is O non O - O significant O . O Family O Cancer O Incidence O in O Relation O to O CHEK2 O Germline O Mutations O Following O an O initial O report O of O a O family O with O a O CHEK2 O germline O mutation O expressing O an O increased O cancer O incidence O resembling O the O Li O - O Fraumeni O syndrome O [ O 24 O ] O , O recent O studies O have O revealed O the O more O common O CHEK2 O mutations O to O be O associated O with O a O moderately O increased O risk O of O breast O and O colorectal O cancers O . O We O hypothesized O that O CHEK2 O mutations O having O a O detrimental O effect O on O drug O sensitivity O could O be O associated O with O a O more O aggressive O , O Li O - O Fraumeni O or O a O Li O - O Fraumeni O - O like O ( O LFL O ) O cancer O syndrome O [ O 48 O ] O . O Except O from O the O patient B harboring O the O Ile364Thr O mutation O who O did O not O have O any O known O congestion O of O cancer O disease O in O the O family O , O a O detailed O assessment O of O family O cancer O history O was O performed O for O each O patient B harboring O a O germline O CHEK2 O mutation O .

O It O should O be O noted O , O however O , O that O two O brothers O of O her O fathers O mother O had O prostate O cancer O , O and O two O siblings O of O his O father O having O hepatocellular O carcinoma O and O bladder O cancer O , O respectively O ) O , O while O the O other O expressed O a O disease O pattern O resembling O what O has O been O seen O with O the O more O common O CHEK2 O mutations O , O like O del1100C O [ O 25 O ] O . O Discussion O TP53 O plays O a O key O role O as O a O tumor O suppressor O gene O . O Its O protein O product O activates O processes O such O as O growth O arrest O , O DNA O repair O , O apoptosis O and O / O or O senescence O in O response O to O genotoxic O damage O as O well O as O oncogene O activity O [ O 49 O ] O , O [ O 50 O ] O . O Despite O being O extensively O studied O , O critical O issues O regarding O regulation O of O the O p53 O protein O remain O poorly O understood O , O and O conflicting O evidence O obtained O in O different O experimental O systems O make O the O clinical O relevance O of O experimental O data O questionable O . O Chemoresistance O is O the O main O obstacle O to O cancer O cure O in O most O malignancies O , O including O breast O cancer O . O Previously O , O we O found O TP53 O mutations O affecting O the O L2 O / O L3 O DNA O binding O domain O to O be O associated O with O lack O of O responsiveness O to O doxorubicin O monotherapy O [ O 13 O ] O as O well O as O mitomycin O and O 5 O - O fluoro O - O uracil O in O concert O [ O 14 O ] O . O However O , O some O tumors O revealed O therapy O resistance O despite O harboring O wild O - O type O TP53 O . O Postulating O that O these O tumors O may O harbor O genetic O disturbances O in O genes O playing O a O key O role O in O the O p53 O pathway O , O we O here O sequenced O TP53 O along O with O CHEK2 O and O p14 O ( O ARF O ) O , O the O latter O two O known O to O play O a O critical O role O as O p53 O activators O , O in O tumors O from O 109 O patients B treated O with O epirubicin O monotherapy O . O Our O results O confirm O TP53 O mutations O , O in O particular O those O affecting O the O L2 O / O L3 O domains O , O to O be O associated O with O drug O resistance O . O Most O importantly O , O we O also O found O CHEK2 O mutations O generating O a O non O - O functional O protein O in O our O in O vitro O assays O to O be O associated O with O drug O resistance O . O In O contrast O , O none O of O our O tumors O harbored O either O mutations O or O expressed O promoter O hypermethylations O affecting O the O p14 O . O Based O on O in O vitro O assays O , O we O were O able O to O classify O the O different O Chk2 O mutants O with O respect O to O dimerization O capability O as O well O as O kinase O activity O ( O Chk2 O autophosphorylation O and O Cdc25 O substrate O phosphorylation O ) O . O In O addition O , O the O kinase O activities O of O the O Chk2 O wild O - O type O / O mutant O complexes O were O monitored O in O co O - O transfection O experiments O . O Notably O , O each O point O mutation O ( O except O for O Arg117Gly O ) O revealed O similar O relative O kinase O efficacy O whether O co O - O transfected O with O wild O - O type O Chk2 O or O not O ( O Figure O 3 O and O 4 O ) O . O Cells O co O - O transfected O with O Arg117Gly O and O wild O - O type O Chk2 O revealed O kinase O activity O , O probably O due O to O the O contribution O of O the O wild O type O protein O in O Chk2 O mutant O - O wild O - O type O heterodimers O . O In O contrast O , O cells O transfected O with O Arg95Ter O revealed O no O kinase O activity O whether O co O - O transfected O with O wild O - O type O Chk2 O or O not O , O clearly O distinguishing O this O mutation O from O the O others O ( O Figure O 3 O and O 5 O ) O . O All O in O vitro O assays O were O based O on O transfection O of O the O U O - O 2 O - O OS O cell O line O , O a O cell O line O known O to O express O wild O - O type O Chk2 O at O low O levels O , O and O previously O used O by O other O investigators O to O study O Chk2 O activity O [ O 44 O ] O , O [ O 45 O ] O , O [ O 46 O ] O . O Since O we O were O not O able O to O obtain O satisfactory O technical O quality O of O the O kinase O assay O in O cell O lines O negative O for O Chk2 O ( O HCT O 15 O and O HCT O 116 O ) O , O we O assessed O potential O background O kinase O activity O due O to O endogenous O Chk2 O by O performing O western O blot O analysis O revealing O the O endogenous O levels O of O Chk2 O in O U O - O 2 O - O OS O cells O to O be O non O - O significant O compared O to O the O exogenously O expressed O Chk2 O levels O ( O data O not O shown O ) O . O We O also O performed O a O separate O kinase O assay O , O directly O comparing O the O effect O of O binding O partners O for O the O dimerizing O Arg117Gly O and O the O non O - O dimerizing O Arg95Ter O . O This O assay O also O revealed O the O contribution O of O endogenous O Chk2 O to O be O non O - O significant O ( O Figure O 5 O ) O . O Taking O our O in O vitro O findings O together O with O in O vivo O observations O , O our O present O data O confirm O that O the O functionally O defective O CHEK2 O Arg95Ter O mutation O , O together O with O LOH O , O is O associated O with O resistance O to O anthracycline O therapy O . O In O contrast O , O the O patient B harboring O the O Ile364Thr O mutation O , O moderately O reducing O phosphorylation O activity O , O responded O well O to O therapy O . O The O other O missense O mutations O ; O Arg117Gly O and O Ile157Thr O were O observed O among O patients B receiving O paclitaxel O therapy O only O ; O thus O , O their O influence O on O anthracycline O sensitivity O in O vivo O could O not O be O addressed O . O Yet O , O based O on O the O finding O that O the O Arg117Gly O mutant O expressed O no O intrinsic O activity O , O but O readily O dimerized O to O the O wild O - O type O protein O without O abolishing O its O activity O , O we O hypothesize O that O this O mutation O and O , O probably O , O other O yet O unidentified O CHEK2 O mutations O with O a O similar O lack O of O intrinsic O kinase O activity O , O may O cause O resistance O to O anthracycline O therapy O if O combined O with O LOH O in O breast O cancer O . O Our O present O findings O have O two O major O implications O . O First O , O we O confirm O that O mutations O in O genes O encoding O proteins O located O within O the O same O functional O pathway O may O substitute O for O each O other O with O respect O to O drug O sensitivity O , O revealing O for O the O first O time O a O functional O pathway O critical O to O chemotherapy O response O in O vivo O . O Second O , O the O identification O of O mutations O in O the O CHEK2 O but O not O in O the O p14 O ( O ARF O ) O gene O in O resistant O tumors O suggests O that O Chk2 O mediated O phosphorylation O of O p53 O is O a O critical O event O in O executing O anti O - O tumor O effect O as O a O response O to O DNA O damaging O agents O in O breast O cancer O . O This O adds O to O our O understanding O not O only O of O the O function O of O p53 O but O Chk2 O as O well O . O p53 O undergoes O phosphorylation O at O multiple O sites O by O different O kinases O , O including O Chk2 O [ O 51 O ] O . O While O activation O of O the O ATM O leading O to O direct O ( O Ser O 15 O ) O and O Chk2 O - O mediated O ( O Ser O 20 O ) O phosphorylation O of O p53 O is O considered O an O important O mechanism O for O triggering O p53 O activation O in O response O to O DNA O damage O [ O 52 O ] O , O some O reports O suggest O ATM O [ O 53 O ] O and O even O Chk2 O [ O 23 O ] O to O be O redundant O to O this O function O . O Importantly O , O Chk2 O has O been O shown O capable O of O inducing O ATM O - O independent O apoptosis O in O vitro O [ O 21 O ] O . O While O Chk2 O phosphorylates O p53 O at O Ser O 20 O , O thereby O stabilizing O p53 O by O preventing O MDM2 O binding O [ O 19 O ] O , O Chk2 O also O phosphorylates O p53 O at O six O additional O sites O , O including O Ser O 313 O and O Ser O 314 O located O in O the O nuclear O localization O signal O domain O of O p53 O [ O 51 O ] O . O In O addition O , O Chk2 O phosphorylates O other O important O targets O like O BRCA1 O , O Cdc25A O and O Cdc25C O involved O in O DNA O repair O , O G1 O and O G2 O arrest O , O respectively O [ O 54 O ] O . O Despite O the O wide O range O of O known O Chk2 O substrates O relevant O for O DNA O repair O and O cell O cycle O control O , O our O present O findings O that O CHEK2 O mutations O leading O to O non O - O functional O Chk2 O protein O may O substitute O for O p53 O mutations O strongly O advocate O a O role O for O Chk2 O with O respect O to O drug O sensitivity O executed O through O p53 O activation O . O Notably O , O one O of O the O tumors O ( O Epi203 O ) O with O the O Arg95Ter O CHEK2 O mutation O in O addition O harbored O a O somatic O TP53 O mutation O , O Arg175His O , O with O allelic O imbalance O for O the O TP53 O gene O ( O Table O 2 O ) O . O Importantly O , O among O another O four O patients B in O this O study O ( O Epi063 O , O Epi071 O , O Epi087 O , O Epi153 O ) O and O one O patient B from O our O previous O doxorubicin O protocol O [ O 13 O ] O harboring O the O Arg175His O mutation O together O with O allelic O imbalance O for O TP53 O , O all O five O of O these O patients B responded O to O anthracycline O therapy O either O with O a O partial O response O or O stable O disease O . O In O contrast O , O Epi132 O and O the O only O patient B for O whom O we O previously O identified O a O non O - O functional O CHEK2 O mutation O ( O 1368InsA O ; O coding O for O a O non O - O functional O protein O translate O with O cytoplasmic O location O [ O 26 O ] O ) O expressed O resistance O to O epirubicin O and O doxorubicin O , O respectively O . O Arg175His O is O a O p53 O " O hot O - O spot O " O structural O mutation O reported O to O have O defects O with O respect O to O transcriptional O activation O and O also O to O negatively O interact O with O wild O - O type O p53 O [ O 55 O ] O . O While O this O mutation O has O been O shown O to O enhance O chemoresistance O upon O transfection O into O p53 O null O Saos O - O 2 O cells O [ O 56 O ] O , O these O osteosarcoma O - O derived O cells O may O not O necessarily O be O representative O for O breast O cancers O in O vivo O . O Recent O evidence O strongly O support O p53 O to O be O involved O also O in O non O - O transcriptional O mediated O apoptosis O by O interacting O with O the O Bcl O - O 2 O / O Bax O system O [ O 57 O ] O , O and O transcription O - O defect O structural O p53 O mutants O have O been O shown O to O execute O non O - O transcriptional O apoptosis O in O experimental O systems O [ O 58 O ] O . O Concomitant O inactivation O of O Chk2 O and O p53 O in O breast O cancer O has O been O recorded O by O others O [ O 59 O ] O , O and O the O finding O that O a O somatic O mutation O may O generate O a O " O growth O advantage O " O in O tumor O cells O already O harboring O a O germline O CHEK2 O mutation O may O not O implicate O an O effect O on O drug O sensitivity O in O tumors O not O yet O exposed O to O cytotoxic O compounds O . O Rather O , O it O may O indicate O a O growth O advantage O , O probably O related O to O loss O of O p21 O function O . O Notably O , O in O a O previous O study O we O found O the O p21 O polymorphism O G251A O to O be O associated O with O an O increased O risk O of O developing O large O breast O cancers O but O to O have O no O effect O on O drug O sensitivity O [ O 60 O ] O , O indicating O that O growth O rate O and O drug O resistance O may O be O regulated O independently O .

O As O mentioned O above O , O removing O TP53 O mutated O tumors O including O the O double O - O mutated O Epi203 O from O statistical O analysis O , O CHEK2 O mutation O status O still O predicted O for O resistance O to O anthracycline O therapy O . O In O addition O , O removing O the O tumors O harboring O the O Arg175His O mutation O from O the O p53 O " O L2 O / O L3 O " O group O strengthened O the O correlation O to O lack O of O treatment O response O to O epirubicin O ( O p O = O 0 O . O 0005 O ) O . O Comparing O the O effects O of O mutations O in O the O CHEK2 O gene O to O TP53 O mutations O indirectly O underlines O the O importance O of O the O role O of O Chk2 O to O chemoresistance O . O Our O present O findings O as O well O as O results O from O our O previous O studies O [ O 13 O ] O , O [ O 14 O ] O revealed O that O about O 50 O % O of O the O patients B with O tumors O harboring O TP53 O L2 O / O L3 O mutations O to O be O non O - O responders O to O primary O therapy O . O In O contrast O , O all O our O three O patients B harboring O a O non O - O functional O CHEK2 O mutation O ( O the O two O Arg95Ter O mutated O patients B here O and O our O previous O patient B harboring O the O 1368InsA O ) O expressed O primary O resistance O to O therapy O . O We O previously O hypothesized O that O therapy O response O in O tumors O harboring O TP53 O L2 O / O L3 O mutations O could O be O due O to O redundant O pathways O acting O in O concert O [ O 3 O ] O . O Although O no O definite O conclusion O should O be O drawn O from O a O limited O number O of O observation O , O the O fact O that O Chk2 O not O only O phosphorylates O p53 O but O also O phosphorylates O other O substrates O such O as O Cdc25A O and O Cdc25C O [ O 54 O ] O and O E2F1 O in O response O to O etoposide O - O induced O DNA O damage O [ O 61 O ] O may O indicate O that O inactivation O of O redundant O pathways O could O take O place O in O parallel O . O The O literature O remains O inconsistent O with O respect O to O whether O the O border O amino O acids O 163 O , O 195 O , O 236 O and O 251 O should O be O included O in O the O p53 O L2 O and O L3 O domains O [ O 12 O ] O . O Taking O a O conservative O approach O , O we O classified O patient B Epi56 O , O harboring O a O mutation O in O codon O 163 O , O as O a O L2 O / O L3 O mutant O . O The O patient B harboring O this O mutation O responded O to O therapy O ( O PR O ) O . O If O this O mutation O was O classified O as O outside O the O L2 O domain O , O our O p O - O value O had O been O strengthened O from O p O = O 0 O . O 0136 O to O p O = O 0 O . O 0096 O . O Germline O mutations O in O TP53 O cause O the O Li O - O Fraumeni O and O Li O - O Fraumeni O - O like O cancer O disposition O syndromes O . O However O , O while O the O germline O and O somatic O mutations O associated O with O these O syndromes O reveal O a O preference O for O the O same O codons O [ O 48 O ] O , O TP53 O mutations O affecting O the O DNA O - O binding O domains O seem O associated O with O a O poor O prognosis O [ O 62 O ] O , O [ O 63 O ] O , O [ O 64 O ] O and O , O in O particular O , O drug O resistance O [ O 14 O ] O , O [ O 40 O ] O in O breast O cancer O . O Thus O , O tumor O suppression O and O tumor O cell O response O to O chemotherapeutics O may O involve O different O parts O of O p53 O protein O function O . O Following O an O initial O report O identifying O a O CHEK2 O mutation O in O a O family O expressing O characteristics O of O the O Li O - O Fraumeni O syndrome O [ O 65 O ] O , O recent O evidence O has O linked O CHEK2 O founder O mutations O to O a O moderately O increased O risk O of O breast O - O and O colorectal O cancers O with O some O additional O disposition O for O other O malignancies O as O well O [ O 66 O ] O . O However O , O cancer O incidence O and O phenotypes O did O not O reveal O an O aggressive O Li O - O Fraumeni O or O Li O - O Fraumeni O - O like O tumor O pattern O . O Similar O to O the O two O patients B in O our O paclitaxel O treatment O arm O harboring O the O rare O but O previously O characterized O mutation O Arg117Gly O and O the O patient B with O the O Ile157Thr O mutation O , O they O expressed O a O moderately O increased O risk O of O breast O and O gastrointestinal O cancers O ( O Fig O . O 6 O ) O . O Thus O , O CHEK2 O resembles O TP53 O in O as O much O as O there O seems O to O be O no O direct O correlation O between O effects O of O individual O mutations O with O respect O to O tumor O suppression O and O drug O resistance O . O Our O finding O that O TP53 O mutations O located O to O the O DNA O - O binding O domains O predicts O drug O resistance O may O indicate O transcriptional O mechanisms O to O be O involved O in O drug O - O induced O cell O death O . O p53 O induced O apoptosis O has O been O associated O with O transcriptional O induction O of O genes O including O Puma O and O Noxa O as O well O as O Bax O in O experimental O systems O [ O 55 O ] O , O [ O 67 O ] O , O [ O 68 O ] O . O Yet O , O recent O evidence O has O revealed O p53 O to O induce O apoptosis O through O non O - O transcriptional O mechanisms O by O direct O protein O interactions O with O members O of O the O Bcl O - O 2 O / O Bax O system O and O mitochondrial O release O of O cytochrom O c O [ O 57 O ] O , O [ O 69 O ] O . O In O deed O , O there O is O evidence O that O the O DNA O - O binding O domains O , O in O particular O the O L3 O part O of O the O protein O , O may O be O critical O also O to O transcriptional O - O independent O apoptosis O [ O 70 O ] O . O Of O particular O note O is O the O finding O that O Chk2 O may O regulate O transcriptional O - O independent O p53 O - O mediated O apoptosis O in O response O to O DNA O - O damage O created O through O ionizing O irradiation O [ O 71 O ] O . O Interestingly O , O Krajewski O et O al O [ O 72 O ] O reported O low O expression O of O Bax O assessed O by O immunostaining O to O be O associated O with O a O low O response O to O chemotherapy O in O metastatic O breast O cancer O . O Although O no O conclusion O should O be O drawn O at O this O stage O , O together O these O findings O are O consistent O with O the O challenging O hypothesis O that O transcription O - O independent O activation O of O Bax O following O Chk2 O - O phosphorylation O may O represent O a O key O pathway O in O p53 O dependent O cell O death O in O breast O cancer O in O vivo O . O p14 O acts O by O releasing O p53 O from O MDM2 O binding O , O and O has O been O related O to O oncogene O - O induced O p53 O activation O [ O 73 O ] O . O Recently O , O p14 O was O shown O to O affect O p53 O by O additional O mechanisms O , O including O acetylations O [ O 74 O ] O , O response O to O ionizing O radiation O in O human B fibroblasts O [ O 75 O ] O , O and O tumor O - O suppression O following O ionizing O radiation O in O mice B [ O 76 O ] O , O [ O 77 O ] O . O These O findings O further O links O the O retinoblastoma O and O p53 O pathways O [ O 28 O ] O . O As O such O , O we O believe O the O negative O finding O with O respect O to O its O role O in O chemoresistance O adds O important O information O . O Contrasting O earlier O findings O by O us O and O others O [ O 15 O ] O , O a O recent O study O revealed O TP53 O mutations O to O be O associated O with O increased O likelihood O of O having O a O complete O response O to O chemotherapy O [ O 16 O ] O . O These O results O may O not O necessarily O be O at O conflict O . O In O the O latter O study O , O patients B received O treatment O with O a O " O dose O - O dense O " O chemotherapy O regimen O ; O if O confirmed O , O the O combined O data O may O outline O a O therapeutic O indication O for O aggressive O dose O - O dense O therapy O based O on O tumor O TP53 O / O CHEK2 O status O . O So O far O attempts O to O identify O single O markers O and O , O more O recently O , O gene O expression O arrays O predicting O chemoresistance O have O not O proved O successful O ( O see O refs O in O [ O 9 O ] O , O [ O 10 O ] O ) O . O The O findings O presented O here O reveal O for O the O first O time O defects O in O a O functional O gene O cascade O to O be O associated O with O drug O resistance O in O a O human B cancer O in O vivo O . O Moreover O , O the O findings O are O made O in O breast O cancer O , O the O most O frequent O malignant O disease O among O women O in O the O industrialized O world O , O and O relate O to O resistance O to O anthracyclines O , O the O type O of O cytotoxic O compounds O most O frequently O employed O for O this O malignancy O . O While O the O only O study O we O are O aware O of O comparing O TP53 O mutation O status O in O primaries O and O their O distant O metastases O suggested O an O increasing O fraction O of O tumors O to O express O mutated O TP53 O during O progression O [ O 78 O ] O , O we O do O not O know O the O potential O contribution O of O either O TP53 O or O CHEK2 O mutations O to O drug O resistance O in O micrometastases O or O in O metastatic O disease O . O Yet O the O finding O that O one O of O our O non O - O functional O CHEK2 O mutations O associated O with O chemoresistance O ( O 1368InsA O ) O occurred O as O a O somatic O , O not O germline O mutation O , O suggest O such O mutations O may O be O selected O for O during O tumor O progression O . O We O propose O the O findings O presented O here O provide O important O beacons O identifying O a O functional O pathway O [ O 3 O ] O likely O to O be O disturbed O through O different O mechanisms O in O relation O to O therapy O resistance O in O advanced O disease O . O In O conclusion O , O we O believe O our O findings O here O that O mutations O in O the O TP53 O and O CHEK2 O genes O each O may O cause O resistance O to O anthracycline O therapy O in O primary O tumors O to O have O wide O implications O to O future O research O in O this O area O . O While O results O from O experimental O systems O are O mandatory O generating O hypotheses O , O conflicting O data O from O in O vitro O studies O underlines O the O pivotal O role O of O identifying O defects O associated O with O therapy O resistance O in O vivo O . O Either O through O mutations O of O the O genes O themselves O , O or O inactivation O of O this O functional O cascade O through O co O - O factors O , O we O believe O identification O of O the O Chk2 O - O p53 O axis O as O critical O to O anthracycline O therapy O response O provides O a O functional O clue O for O further O investigations O in O this O area O . O Host O immunity O in O the O protective O response O to O vaccination O with O heat O - O killed O Burkholderia B mallei I Abstract O Background O We O performed O initial O cell O , O cytokine O and O complement O depletion O studies O to O investigate O the O possible O role O of O these O effectors O in O response O to O vaccination O with O heat O - O killed O Burkholderia B mallei I in O a O susceptible O BALB O / O c O mouse B model O of O infection O . O Results O While O protection O with O heat O - O killed O bacilli O did O not O result O in O sterilizing O immunity O , O limited O protection O was O afforded O against O an O otherwise O lethal O infection O and O provided O insight O into O potential O host O protective O mechanisms O . O Our O results O demonstrated O that O mice B depleted O of O either O B O cells O , O TNF O - O alpha O or O IFN O - O gamma O exhibited O decreased O survival O rates O , O indicating O a O role O for O these O effectors O in O obtaining O partial O protection O from O a O lethal O challenge O by O the O intraperitoneal O route O . O Additionally O , O complement O depletion O had O no O effect O on O immunoglobulin O production O when O compared O to O non O - O complement O depleted O controls O infected O intranasally O . O Conclusion O The O data O provide O a O basis O for O future O studies O of O protection O via O vaccination O using O either O subunit O or O whole O - O organism O vaccine O preparations O from O lethal O infection O in O the O experimental O BALB O / O c O mouse B model O .

O Background O Burkholderia B mallei I , O the O etiologic O agent O of O glanders O , O is O a O gram O - O negative O , O capsulated O , O non O - O motile O , O facultative O intracelluar O bacterium O .

O However O , O glanders O is O endemic O among O domestic O animals O in O Africa O , O Asia O , O the O Middle O East O , O and O Central O and O South O America O .

O The O group O D O enterococci O include O three O main O species O S B . I faecalis I , O S B . I faecium I , O and O S B . I durans I . O S B . I faecium I cause O a O minority O of O all O cases O of O enterococcal O endocarditis O , O in O those O instances O in O which O enterococci O have O been O speciated O [ O 3 O ] O , O but O they O have O been O more O resistant O both O to O penicillin O and O penicillin O - O aminoglycoside O combinations O than O S B .

O Synergy O was O readily O demonstrable O against O this O organism O by O penicillin O - O streptomycin O and O penicillin O - O gentamicin O combinations O in O vitro O , O but O not O by O penicillin O - O tobramycin O . O DISCUSSION O Among O streptococci O , O the O enterococci O are O unusual O in O their O relative O resistance O to O a O broad O spectrum O of O antimicrobial O agents O , O and O single O - O agent O therapy O is O rarely O bactericidal O against O them O [ O 2 O ] O . O Since O Hunter O ' O s O original O observations O in O 1947 O , O it O has O become O increasingly O clear O that O effective O synergistic O combinations O of O antibiotics O are O necessary O to O successfully O treat O enterococcal O endocarditis O [ O 1 O ] O . O Although O S B . I faecalis I represents O the O majority O of O clinical O enterococcal O isolates O , O S B . I faecium I nonetheless O comprises O 5 O - O 10 O percent O of O these O isolates O in O some O series O [ O 3 O , O 4 O ] O . O Moreover O , O major O differences O exist O in O antimicrobial O susceptibility O and O resistance O to O penicillin O - O aminoglycoside O synergism O between O these O two O enterococcal O species O . O The O MIC O of O penicillin O against O S B . I faecium I is O higher O and O this O organism O is O more O resistant O to O a O number O of O different O combinations O of O penicillin O and O various O aminoglycosides O than O is O S B . I faecalis I [ O 6 O ] O . O The O mechanisms O of O resistance O exhibited O by O enterococci O to O penicillin O - O aminoglycoside O synergy O have O been O investigated O . O Clinically O achievable O levels O of O amino O 246 O S B . I FAECIUM B ENDOCARDITIS O glycosides O are O generally O ineffective O against O enterococci O . O This O intrinsic O low O - O level O resistance O ( O MIC O c O 250 O isg O / O ml O ) O is O thought O to O be O the O result O of O poor O antibiotic O penetration O of O the O bacterial O cell O wall O . O However O , O in O the O presence O of O antibiotics O that O interfere O with O cell O wall O synthesis O , O there O is O enhanced O aminoglycoside O uptake O [ O 7 O ] O . O In O concert O , O these O events O are O the O basis O for O penicillin O - O aminoglycoside O synergism O . O Ribosomal O resistance O of O the O 30S O subunit O to O streptomycin O and O defective O uptake O of O gentamicin O in O the O presence O of O penicillin O have O been O reported O mechanisms O of O resistance O among O enterococcal O isolates O [ O 8 O , O 9 O ] O . O However O , O in O the O majority O of O instances O , O failure O of O synergy O involves O plasmid O - O mediated O production O of O aminoglycoside O - O modifying O enzymes O . O For O streptomycin O and O kanamycin O , O plasmid O - O mediated O enzymatic O inactivation O confers O high O - O level O resistance O ( O MIC O > O 2 O , O 000 O Ag O / O ml O ) O and O correlates O with O failure O of O these O aminoglycosides O to O exert O a O synergistic O effect O when O combined O with O penicillin O [ O 10 O , O 11 O ] O . O Plasmid O - O mediated O modifying O enzymes O have O been O found O in O both O S B . I faecalis I and O S B . I faecium I ' O [ O 12 O ] O . O Currently O , O approximately O one O - O half O of O clinical O enterococcal O isolates O demonstrate O high O - O level O resistance O to O streptomycin O and O kanamycin O [ O 13 O ] O . O Combinations O of O penicillin O with O kanamycin O , O tobramycin O , O sisomicin O , O and O netilmicin O have O consistently O failed O to O demonstrate O synergistic O killing O of O S B . I faecium I in O vitro O [ O 6 O ] O . O This O failure O of O synergy O occurs O even O when O high O - O level O resistance O to O these O aminoglycosides O is O not O present O . O The O mechanism O of O resistance O appears O to O be O related O to O the O production O of O an O inactivating O enzyme O that O acetylates O the O aminoglycoside O substrate O at O the O 6 O ' O position1 O [ O 14 O ] O . O The O genetic O basis O for O production O of O this O enzyme O has O not O been O well O - O defined O and O plasmid O transfer O experiments O have O thus O far O been O unsucessful O in O demonstrating O the O encodement O of O this O enzyme O by O extrachromosomal O DNA O [ O 14 O ] O . O Moellering O et O al O . O demonstrated O in O vivo O , O utilizing O the O rabbit B model O of O endocarditis O , O that O penicillin O and O netilmicin O were O not O efficacious O in O the O treatment O of O endocarditis O caused O by O a O low O - O level O aminoglycoside O - O resistant O strain O of O S B . I faecium I [ O 6 O ] O . O Although O combinations O of O penicillin O with O tobramycin O , O kanamycin O , O or O sisomicin O were O not O evaluated O , O the O authors O postulated O that O the O same O ineffectual O result O would O have O occurred O . O In O the O present O case O , O the O recurrence O of O S B . I faecium I endocarditis O after O six O weeks O of O therapy O with O ampicillin O and O tobramycin O confirms O the O therapeutic O and O clinical O significance O of O their O data O , O and O emphasizes O that O tobramycin O is O not O an O aminoglycoside O to O be O used O for O treatment O of O serious O S B . I faecium I infections O . O Bacterial O tolerance O has O been O suggested O as O a O possible O basis O for O therapeutic O failures O , O particularly O in O the O treatment O of O infections O caused O by O Staphylococcus B aureus I with O defects O in O the O production O of O autolysins O . O MBCs O are O generally O several O - O fold O higher O than O MICs O and O this O phenomenon O appears O to O be O associated O with O the O autolysin O defect O [ O 5 O ] O . O Lorian O has O also O described O the O formation O of O numerous O aberrant O cross O - O walls O by O S B . I faecalis I grown O in O the O presence O of O subinhibitory O concentrations O of O penicillin O [ O 15 O ] O . O MBCs O were O only O slightly O higher O than O MICs O for O the O three O S B . I faecium I variants O obtained O from O our O patient B , O and O they O did O not O appear O to O be O tolerant O strains O of O S B . I faecium I . O There O was O no O evidence O that O any O of O the O morphological O variants O isolated O were O unusually O resistant O to O antibiotics O . O Therefore O , O subsequent O failure O of O therapy O could O not O be O explained O on O the O basis O of O antibiotic O resistance O patterns O . O The O initial O failure O of O ampicillin O and O tobramycin O therapy O may O have O allowed O the O infecting O organism O to O become O better O established O and O more O difficult O to O eradicate O from O the O valve O .

O persistent O focus O of O infection O causing O the O LAD O lesion O seen O by O arteriography O may O have O slowly O resolved O and O accounted O for O the O apparent O failure O to O respond O to O synergistic O combinations O of O antibiotics O .

O Relapse O of O endocarditis O might O have O been O anticipated O on O the O basis O of O previous O experimental O data O showing O lack O of O synergy O when O tobramycin O is O used O against O this O organism O .

O 2249 O Nucleic O Acids O Research O of O introns O present O in O individual O hybrid O molecules O was O observed O . O The O reason O for O this O may O be O due O to O size O heterogeneity O of O the O a2 O mRNA O used O as O a O complementary O probe O . O Although O the O a2 O mRNA O was O extensively O purified O ( O 2 O ) O , O some O degradation O was O likely O present O .

O The O most O likely O a2 O genetic O regions O containing O such O introns O are O exons O " O g O " O and O " O m O " O . O Small O " O protrusions O " O were O sometimes O observed O within O these O exons O that O could O represent O small O introns O . O Very O small O introns O have O been O reported O for O tRNA O genes O ( O 12 O , O 13 O ) O , O and O it O will O be O necessary O to O sequence O these O regions O of O SpC3 O to O determine O if O such O introns O are O present O within O the O a2 O sheep B genome O . O The O existence O of O mRNAs O comprised O of O sequences O complementary O to O noncontiguous O regions O in O a O DNA O genome O was O first O described O for O adenovirus B ( O 14 O , O 15 O ) O and O simian O virus O ( O 16 O , O 17 O ) O genes O . O Similar O observations O were O soon O reported O for O eukaryotic O genes O , O including O serum O albumin O ( O 18 O ) O , O conalbumin O ( O 19 O ) O , O fibroin O ( O 20 O ) O , O s O globin O ( O 21 O , O 22 O ) O , O growth O hormones O ( O 23 O , O 24 O ) O , O immunoglobulin O ( O 25 O ) O , O lysozyme O ( O 26 O ) O , O ovalbumin O ( O 27 O - O 29 O ) O , O ovomucoid O ( O 30 O ) O , O rRNA O ( O 31 O - O 34 O ) O , O tRNA O ( O 12 O , O 13 O ) O , O and O vitellogenin O ( O 35 O ) O . O The O precise O number O or O occurrence O of O introns O within O these O genes O does O not O seem O to O follow O any O clear O pattern O . O However O , O the O genes O for O albumin O , O conalbumin O , O lysozyme O , O ovalbumin O , O and O ovomucoid O exhibit O a O structural O organization O comparable O to O the O a2 O collagen O gene O . O All O of O these O genes O are O composed O of O numerous O small O exons O , O usually O less O than O 250 O base O pairs O , O and O introns O which O show O a O large O size O variation O within O an O individual O gene O . O Within O all O of O these O genomes O , O the O DNA O regions O required O for O coding O structural O formation O are O 4 O to O 7 O times O longer O than O the O corresponding O mRNA O coding O sequences O . O As O with O the O a2 O collagen O gene O , O a O large O unique O exon O at O the O extreme O 3 O ' O end O is O also O present O in O the O ovalbumin O gene O ( O 36 O , O 37 O ) O . O In O the O a2 O gene O , O this O exon O was O 800 O to O 900 O nucleotides O in O length O , O while O in O the O ovalbumin O gene O the O exon O contained O 1 O , O 030 O base O pairs O . O Interestingly O , O this O ovalbumin O exon O contained O 634 O - O 650 O base O pairs O ot O DNA O sequence O to O the O 3 O ' O side O of O the O terminator O triplet O , O suggesting O the O ovalbumin O mRNA O has O a O large O untranslated O region O at O the O 3 O ' O end O . O The O consistent O appearance O of O a O small O non O - O hybridized O tail O , O approximately O 100 O nucleotides O in O length O , O in O the O region O where O the O right O arm O of O the O phage O was O ligated O to O the O sheep B genomic O insert O of O SpC3 O very O likely O corresponded O to O the O 3 O ' O poly O A O sequence O of O the O a2 O mRNA O . O This O would O suggest O that O the O a2 O mRNA O coding O sequence O terminates O very O near O or O at O this O point O in O the O genome O . O Previously O published O biochemical O evidence O ( O 2 O ) O obtained O from O restriction O mapping O and O Southern O blot O analysis O using O [ O 32P O ] O - O labeled O chick O a2 O cDNA O probe O supports O 2250 O Nucleic O Acids O Research O this O observation O . O It O is O unclear O what O role O introns O play O in O genetic O expression O . O However O , O it O is O known O that O these O sequences O are O tranncribed O as O part O of O larger O precursor O mRNAs O and O the O introns O are O then O excised O and O the O fragmented O mRNA O chains O covalently O rejoined O ( O 38 O ) O . O Some O evidence O has O recently O accumulated O demonstrating O the O existence O of O precursor O a2 O mRNAs O ( O 39 O , O 40 O ) O . O However O , O if O the O introns O in O the O a2 O gene O are O transcribed O in O their O entirety O , O as O has O been O demonstrated O for O the O introns O in O ovalbumin O and O globin O ( O 41 O , O 42 O ) O , O much O larger O precursor O a2 O mRNAs O may O exist O than O those O reported O to O date O . O For O if O the O re O mainder O of O the O a2 O collagen O gene O has O a O structural O organization O comparable O to O the O 60 O % O 3 O ' O portion O that O has O been O analyzed O , O it O is O probable O that O the O a2 O collagen O gene O in O its O entirety O is O dispersed O throughout O a O 30 O kb O DNA O segment O .

O Conclusion O Lower O median O nerve O lesion O , O simulated O by O a O nerve O block O at O the O wrist O , O compromise O normal O motor O function O of O the O thumb O . O A O median O nerve O block O results O in O force O deficits O in O all O directions O , O with O the O most O severe O impairment O in O abduction O and O flexion O . O From O our O results O , O such O a O means O of O motor O function O assessment O can O potentially O be O applied O to O functionally O evaluate O peripheral O neuropathies O . O Introduction O The O thumb O has O unique O anatomical O and O biomechanical O characteristics O that O are O required O to O perform O many O manipulative O tasks O . O Thumb O motor O dysfunction O resulting O from O neuromuscular O and O musculoskeletal O pathologies O severely O hinders O the O performance O of O these O daily O tasks O . O Clinical O treatment O , O prevention O protocols O , O and O rehabilitation O efficacy O requires O a O thorough O understanding O of O thumb O motor O capabilities O , O as O well O as O its O associated O functional O deficit O . O Investigations O of O underlying O pathological O mechanism O of O the O thumb O help O advance O clinical O treatments O such O as O tendon O transfers O [ O 1 O ] O , O functional O electrical O stimulation O [ O 2 O ] O and O plasticity O suppression O [ O 3 O ] O . O Measurement O of O strength O during O maximum O voluntary O contraction O is O a O simple O and O direct O means O of O assessing O neuromuscular O function O . O Popular O instruments O used O for O quantitative O assessment O of O thumb O strength O are O pinch O dynamometers O . O The O pinch O output O , O however O , O provides O limited O information O about O thumb O motor O function O in O that O it O offers O a O single O generic O force O in O one O specific O direction O . O Each O muscle O / O tendon O within O the O thumb O has O a O distinct O anatomical O origin O and O insertion O , O suggesting O its O external O force O potential O in O a O particular O direction O [ O 4 O - O 6 O ] O . O Hence O , O evaluation O of O strengths O in O multiple O directions O offers O insight O concerning O the O motor O capacity O of O individual O muscles O . O Force O production O of O a O digit O has O been O measured O in O various O directions O such O as O flexion O / O extension O [ O 7 O , O 8 O ] O , O abduction O / O adduction O [ O 9 O - O 14 O ] O , O or O in O combined O directions O [ O 15 O , O 16 O ] O . O Bourbonnais O et O al O . O developed O an O apparatus O to O measure O thumb O force O production O in O eight O directions O in O the O transverse O plane O of O the O thumb O and O investigated O force O dependence O on O the O direction O of O effort O [ O 15 O ] O . O Yokogawa O and O Hara O measured O index O fingertip O forces O in O various O directions O within O the O flexion O / O extension O plane O [ O 8 O ] O . O Recently O , O we O developed O experimental O apparatuses O to O measure O multi O - O directional O forces O of O a O digit O in O its O transverse O plane O [ O 17 O - O 19 O ] O . O From O these O multi O - O directional O forces O we O constructed O force O envelopes O representative O of O the O characteristic O force O output O pattern O of O a O digit O [ O 17 O - O 19 O ] O . O Disorders O resulting O from O traumatic O injuries O to O and O various O diseases O of O these O nerves O are O common O in O clinical O practice O . O Clinical O manifestations O of O hand O dysfunction O are O distinctive O depending O on O the O nerve O involved O . O For O example O , O thenar O atrophy O is O a O major O clinical O observation O affecting O thumb O function O at O the O later O stages O of O compression O neuropathy O of O the O median O nerve O . O Several O studies O have O been O conducted O to O investigate O the O effects O of O simulated O peripheral O neuropathies O using O local O anesthetization O [ O 5 O , O 16 O , O 20 O , O 21 O ] O . O Kozin O et O al O . O [ O 21 O ] O studied O the O effects O of O median O and O ulnar O nerve O blocks O on O grip O and O pinch O strength O and O showed O significant O decreases O following O nerve O blockage O [ O 21 O ] O . O Boatright O and O Kiebzak O [ O 20 O ] O investigated O the O effects O of O median O nerve O block O on O thumb O abduction O strength O . O Kaufman O et O al O . O [ O 5 O ] O measured O isometric O thumb O forces O in O eight O directions O together O with O electromyographic O signals O of O thumb O muscles O after O block O of O the O median O nerve O . O Labosky O and O Waggy O [ O 22 O ] O studied O the O strength O related O to O grip O , O pinch O , O thumb O adduction O , O thumb O abduction O , O and O finger O flexion O after O radial O nerve O block O [ O 22 O ] O . O Kuxhaus O studied O the O three O dimensional O feasible O force O set O at O the O thumb O - O tip O before O and O after O ulnar O nerve O block O and O reported O this O to O be O a O reproducible O and O sensitive O means O to O detect O impairment O . O The O purpose O of O this O study O was O to O utilize O our O developed O apparatus O and O protocols O to O investigate O the O effects O of O lower O median O nerve O lesion O on O thumb O motor O function O . O The O lesion O was O simulated O by O blocking O the O median O nerve O at O the O wrist O using O an O anesthetic O . O We O hypothesized O that O a O median O nerve O block O would O cause O ( O 1 O ) O a O decrease O in O force O production O , O which O would O be O direction O - O dependent O with O the O most O severe O reduction O in O the O abduction O direction O , O and O ( O 2 O ) O a O decrease O in O the O force O envelope O area O and O force O quadrant O area O , O with O the O greatest O decrease O in O the O abduction O quadrant O . O Methods O Subjects O Six O healthy O male O subjects O ( O mean O age O : O 26 O . O 9 O + O / O - O 5 O . O 1 O years O ) O participated O in O this O study O . O The O subjects O had O no O previous O history O of O neuromuscular O or O musculoskeletal O disorders O of O the O upper O extremities O . O Each O subject O signed O an O informed O consent O form O approved O by O the O Institutional O Review O Board O prior O to O participating O in O the O experiment O . O Median O nerve O block O Injections O were O performed O under O aseptic O conditions O while O the O subjects O sat O with O the O forearm O supinated O and O the O wrist O slightly O extended O . O After O the O skin O at O the O palmer O area O of O the O wrist O was O cleaned O with O alcohol O , O 4 O mL O of O 0 O . O 5 O % O bupivacaine O hydrochloride O ( O Astra O Pharmaceuticals O , O Westborough O , O MA O , O USA O ) O was O injected O into O the O carpal O tunnel O with O a O sterile O 25 O - O gauge O short O - O bevel O needle O . O The O needle O was O inserted O through O the O transverse O carpal O ligament O in O line O with O the O radial O border O of O the O fourth O digit O slightly O ulnar O to O the O palmaris O longus O tendon O at O the O level O of O the O distal O wrist O crease O . O Forty O minutes O was O allowed O for O the O median O nerve O block O to O reach O complete O effectiveness O [ O 23 O ] O and O was O verified O using O the O Semmes O - O Weinstein O monofilament O test O . O The O average O monofilament O score O was O 2 O . O 85 O across O the O five O digits O before O nerve O block O . O About O 40 O minutes O after O nerve O injection O , O little O sensory O impairment O occurred O in O the O ulnar O distribution O ( O score O = O 3 O . O 22 O ) O , O while O the O sensory O score O in O the O median O distribution O was O greater O than O 6 O . O 15 O . O The O effects O of O nerve O block O lasted O more O than O 6 O hours O with O all O subjects O regaining O normal O hand O function O within O 12 O hours O . O Testing O apparatus O The O experimental O apparatus O was O designed O and O constructed O to O measure O maximum O voluntary O contraction O forces O of O any O digit O at O any O point O along O the O digit O . O Force O application O was O possible O in O any O direction O within O the O transverse O plane O of O the O longitudinal O axis O of O the O digit O . O The O apparatus O consisted O of O position O control O accessories O , O a O force O transducer O , O and O a O custom O fitted O aluminum O ring O attached O to O the O transducer O ( O Figure O 1A O , O 1B O ) O . O The O transducer O ( O Mini40 O , O ATI O Industrial O Automation O , O NC O , O USA O ) O , O capable O of O measuring O 6 O degrees O of O freedom O forces O and O moments O , O was O attached O to O a O mounting O clamp O via O an O aluminum O adapter O plate O while O the O aluminum O ring O was O secured O to O the O tool O side O of O the O transducer O using O a O custom O adapter O . O The O ring O served O as O a O connection O anchor O for O the O transducer O and O the O digit O . O The O force O transducer O and O ring O attachment O were O positioned O in O a O desired O orientation O using O an O aluminum O slide O rail O , O tubing O , O and O lockable O mounting O clamps O ( O 80 O / O 20 O Inc O . O , O Columbia O City O , O IN O , O USA O ) O . O The O slide O rail O was O secured O to O an O aluminum O base O plate O . O Foam O padded O wooden O blocks O with O two O locking O straps O secured O the O arm O to O the O base O plate O . O The O analog O outputs O from O the O transducer O were O digitized O using O a O 16 O - O bit O analog O - O to O - O digital O converter O ( O PCI O - O 6031 O , O National O Instruments O , O TX O , O USA O ) O . O The O X O ( O abduction O / O adduction O ) O and O Y O ( O flexion O / O extension O ) O force O components O in O the O transverse O plane O were O displayed O on O the O screen O while O the O subject O performed O a O force O production O task O . O The O resolutions O of O the O force O transducer O in O its O axial O ( O flexion O / O extension O ) O and O horizontal O ( O abduction O / O adduction O ) O directions O were O 0 O . O 16 O N O and O 0 O . O 08 O N O , O respectively O . O A O personal O computer O equipped O with O LabVIEW O ( O National O Instrument O , O TX O , O USA O ) O was O used O for O force O data O acquisition O , O display O , O and O processing O . O Experimental O procedures O Each O subject O was O tested O before O and O after O median O nerve O block O . O The O nerve O block O procedures O were O performed O immediately O after O the O completion O of O the O first O testing O session O . O Post O - O block O testing O started O after O the O verification O of O complete O median O nerve O block O , O approximately O 40 O minutes O after O the O injection O . O During O each O test O , O the O subject O was O seated O in O a O chair O adjacent O to O the O testing O station O modified O with O a O wooden O board O to O align O their O back O vertically O throughout O the O trials O . O The O subjects O rested O their O forearm O on O padded O wooden O blocks O positioning O their O shoulder O in O approximately O 60 O degrees O of O frontal O plane O abduction O . O Nylon O straps O fitted O with O plastic O snap O locking O mechanisms O secured O the O forearm O and O minimized O the O intervention O of O the O elbow O and O shoulder O during O thumb O force O application O . O Subjects O grasped O a O vertical O dowel O secured O to O the O distal O end O of O the O wooden O blocks O in O a O midprone O position O . O Formable O thermoplastic O braces O were O used O to O fix O the O elbow O in O 90 O degrees O of O flexion O , O and O the O wrist O in O 20 O degrees O of O extension O and O 0 O degrees O of O ulnar O deviation O . O A O metallic O brace O was O used O to O fix O the O interphalangeal O joint O of O the O thumb O in O full O extension O . O The O aluminum O ring O was O placed O around O the O middle O of O the O proximal O phalanx O and O oriented O to O accommodate O comfortable O thumb O position O with O the O metacarpophalangeal O joint O flexed O approximately O 15 O degrees O . O Prior O to O testing O , O a O line O was O drawn O on O the O proximal O phalange O at O the O midpoint O between O the O interphalangeal O and O metacarpophalangeal O joints O . O The O alignment O of O the O ring O with O the O circumferential O line O standardized O the O location O of O force O application O within O and O between O subjects O . O As O force O application O was O at O the O middle O of O the O proximal O phalanx O , O mechanical O action O pertains O to O both O the O metacarpophalangeal O and O carpometacarpal O joints O . O We O chose O the O terminology O of O flexion O / O extension O and O adduction O / O adduction O based O on O the O mechanical O action O with O respect O to O the O metacarpophalangeal O joint O . O With O the O thumb O in O the O ring O ( O Figure O 1B O ) O , O extension O and O flexion O occurred O in O parallel O with O the O palm O , O and O abduction O and O adduction O occurred O in O a O plane O perpendicular O to O the O palm O . O Each O subject O performed O 15 O circumferential O MVC O trials O with O randomized O starting O directions O ( O Figure O 1C O ) O . O The O subject O was O allotted O 15 O seconds O to O complete O each O circumferential O trial O , O and O was O instructed O to O use O the O entire O time O allotted O to O traverse O the O perimeter O of O the O ring O once O . O A O dot O generated O on O the O computer O screen O was O programmed O to O traverse O a O circle O within O 15 O seconds O to O provide O the O subject O with O directional O feedback O of O their O force O application O . O Subjects O were O given O 60 O seconds O of O rest O between O each O circumferential O trial O . O Each O subject O was O familiarized O with O the O task O with O a O few O practice O trials O . O Data O were O collected O from O each O subject O at O 100 O samples O per O second O producing O a O total O of O 22 O , O 500 O pairs O of O force O components O from O the O 15 O circumferential O trials O . O Our O previous O study O [ O 19 O ] O indicated O that O the O testing O protocol O did O not O cause O noticeable O fatigue O . O Force O envelope O and O quadrants O Data O from O multiple O circumferential O trials O were O accumulated O to O construct O a O force O envelope O . O The O procedures O to O generate O a O force O envelope O were O as O follows O : O Cartesian O force O coordinates O ( O Xi O , O Yi O ) O were O transformed O into O polar O coordinates O ( O R O alpha O , O alpha O ) O , O where O R O alpha O was O the O force O magnitude O at O an O angular O position O alpha O . O Each O alpha O was O rounded O to O the O nearest O integer O ranging O from O 0 O to O 359 O degrees O . O The O maximum O , O F O alpha O , O was O determined O from O a O string O of O N O data O points O along O each O radial O line O defined O by O alpha O . O At O the O completion O of O the O 15 O trials O , O there O were O , O on O average O , O N O = O 63 O data O points O on O each O radial O line O of O alpha O based O on O the O distribution O off O the O 22 O , O 500 O data O points O around O 360 O degrees O . O A O moving O average O with O an O interval O of O 10 O degrees O was O applied O to O the O maximal O series O data O F O alpha O ( O alpha O = O 0 O , O 1 O , O 2 O , O . O . O . O , O 359 O ) O to O obtain O filtered O maximal O forces O . O These O forces O formed O a O force O envelope O . O The O area O formed O by O a O force O envelope O was O divided O into O adduction O - O extension O , O extension O - O abduction O , O abduction O - O flexion O , O and O flexion O - O adduction O quadrants O by O radial O lines O oriented O at O 0 O degrees O , O 90 O degrees O , O 180 O degrees O , O and O 270 O degrees O A O quadrant O force O was O represented O using O the O mean O magnitude O of O the O forces O in O that O quadrant O . O The O areas O of O the O entire O envelope O and O each O quadrant O were O calculated O by O summing O the O areas O of O individual O arc O sections O formed O by O the O polar O coordinates O of O the O force O envelope O . O ( O Figure O 2 O ) O .

O Results O Force O envelope O and O directional O forces O Figure O 3 O shows O the O force O envelopes O produced O by O each O subject O ( O A O to O F O ) O before O and O after O median O nerve O block O . O The O post O - O block O force O envelope O was O inside O the O pre O - O block O envelope O for O each O subject O , O indicating O a O decrease O in O force O magnitude O in O all O directions O after O nerve O block O . O Figure O 4 O shows O the O average O pre O - O and O post O - O block O force O envelope O across O all O subjects O . O Force O magnitudes O were O significantly O reduced O after O nerve O block O ( O p O < O 0 O . O 001 O ) O resulting O in O significantly O smaller O force O envelopes O . O The O average O decrease O across O all O directions O was O 27 O . O 9 O % O . O A O maximum O decrease O of O 42 O .

O 3 O % O area O decrease O in O the O flexion O quadrant O . O Discussion O In O this O study O we O simulated O a O lower O median O nerve O lesion O and O evaluated O the O resultant O thumb O motor O function O deficit O . O Our O internal O control O via O pre O - O and O post O - O block O design O offered O a O particular O advantage O of O investigating O the O mechanical O role O of O muscles O innervated O by O a O targeted O nerve O . O The O testing O and O analytical O methods O employed O have O provided O advanced O quantification O of O thumb O motor O function O . O The O results O have O confirmed O our O initial O hypotheses O that O greatest O force O decreases O occurred O in O directions O related O to O abduction O , O and O that O the O post O - O block O thumb O force O envelope O area O was O smaller O than O the O pre O - O block O force O envelope O area O . O Preferential O force O attenuation O in O the O quadrants O of O abduction O and O flexion O after O median O nerve O block O are O in O agreement O with O anatomical O and O neuromuscular O features O of O the O thumb O . O The O median O nerve O innervates O the O abductor O pollicis O brevis O , O the O opponens O pollicis O and O superficial O head O of O the O flexor O pollicis O brevis O , O all O of O which O contribute O to O the O abduction O and O flexion O of O the O thumb O [ O 4 O ] O ; O therefore O , O denervation O of O these O muscles O after O median O nerve O block O would O cause O the O greatest O force O deficit O related O to O median O nerve O function O [ O 5 O ] O . O Additionally O , O as O force O application O moved O towards O adduction O , O the O force O deficit O decreased O as O neuromuscular O control O shifted O from O the O median O nerve O to O the O ulnar O nerve O via O the O first O dorsal O interosseous O and O adductor O pollicis O brevis O . O Force O deficit O in O extension O was O also O comparably O small O as O extension O forces O are O mainly O produced O by O the O extensors O pollicis O brevis O and O longus O originating O in O the O forearm O . O Our O reported O force O decreases O following O a O median O nerve O block O ( O 40 O . O 9 O % O in O abduction O , O 34 O . O 1 O % O in O flexion O ) O were O smaller O than O those O reported O in O the O literature O . O Kozin O et O al O . O [ O 21 O ] O reported O a O 60 O % O decrease O in O pinch O strength O after O a O median O nerve O block O using O mepivicaine O hydrochloride O [ O 21 O ] O . O Boatright O and O Kiebzak O [ O 20 O ] O reported O an O approximate O 70 O % O decrease O in O thumb O abduction O strength O after O median O nerve O block O using O Lidocaine O [ O 20 O ] O . O Kaufman O et O al O . O [ O 5 O ] O stated O that O a O median O nerve O block O with O Lidocaine O almost O completely O diminished O force O production O in O the O abduction O direction O [ O 5 O ] O . O The O discrepancy O may O be O due O to O the O anesthetic O used O and O strength O testing O method O . O Although O the O sensory O block O appeared O to O be O complete O for O each O method O , O the O motor O capabilities O of O the O muscles O associated O with O the O median O nerve O might O or O might O not O be O completely O eliminated O . O Such O a O result O is O largely O dependent O on O a O particular O anesthetic O , O its O concentration O and O dosage O , O as O well O as O the O efficacy O of O the O injection O technique O at O immersing O the O nerve O . O The O methods O of O strength O testing O may O also O help O explain O the O different O magnitudes O of O strength O deficit O after O the O nerve O block O . O All O previous O results O were O based O on O forces O obtained O in O discrete O direction O ( O s O ) O , O and O focused O exertions O , O while O the O current O study O utilized O a O method O of O force O production O in O a O continuous O , O circumferential O and O dynamic O manner O . O Furthermore O , O thumb O motor O performance O can O be O maintained O despite O the O absence O of O certain O individual O muscles O . O For O example O , O Britto O and O Elliot O reported O that O the O loss O of O abductor O pollicis O longus O and O extensor O pollicis O brevis O in O their O two O patients B did O not O show O functional O compromise O of O strength O and O grip O strength O [ O 24 O ] O . O In O a O broader O sense O , O the O neuromuscular O system O has O remarkable O capabilities O to O accomplish O the O same O motor O function O goal O using O different O effectors O and O different O goals O using O the O same O effectors O , O a O phenomenon O so O called O " O motor O equivalence O " O [ O 25 O ] O . O An O unexpected O finding O from O this O study O was O that O the O force O deficit O occurred O in O all O directions O ( O Figure O 4 O ) O . O In O other O words O , O the O median O nerve O block O caused O reduced O force O production O by O those O muscles O not O associated O with O the O median O nerve O . O Several O potential O explanations O exist O to O describe O such O a O phenomenon O . O First O , O the O injection O into O the O carpal O tunnel O at O the O wrist O , O although O localized O , O potentially O diffused O into O the O intrinsic O fascia O of O the O hand O partially O compromising O function O of O the O ulnar O nerve O , O which O innervates O the O adductor O pollicis O . O Although O Semmes O - O Weinstein O monofilament O testing O confirmed O the O continued O sensation O of O the O digits O within O the O ulnar O nerve O distribution O , O it O is O not O inconceivable O that O the O injection O could O have O contaminated O the O ulnar O innervated O muscles O , O the O first O dorsal O interosseous O and O deep O head O of O the O flexor O pollicis O brevis O [ O 20 O ] O . O Secondly O , O thumb O force O in O any O direction O is O produced O by O synergistic O activation O of O the O many O intrinsic O muscles O , O and O as O a O result O , O the O muscular O deficiency O associated O with O one O direction O may O hinder O the O force O production O in O other O directions O by O other O muscles O [ O 5 O , O 22 O ] O . O For O example O , O Kaufman O et O al O . O demonstrated O that O thumb O muscles O not O innervated O by O the O median O nerve O displayed O lower O electromyographical O activation O and O shifted O the O direction O of O maximum O activation O after O a O median O nerve O block O [ O 5 O ] O . O Labosky O and O Waggy O showed O that O a O radial O nerve O block O caused O a O 53 O % O decrease O in O thumb O abduction O strength O because O of O the O lack O of O stabilization O of O the O radial O innervated O extensor O muscles O [ O 22 O ] O . O Consequently O , O deficiency O of O median O innervated O muscles O inherently O limits O force O production O in O other O directions O as O neuromuscular O switching O is O necessary O to O produce O force O in O changing O directions O . O The O median O innervated O muscles O are O the O dominant O abductors O of O the O thumb O metacarpophalangeal O and O carpometacarpal O joint O . O The O more O than O 50 O % O residual O abduction O force O found O in O this O study O suggests O that O the O injection O did O not O totally O block O the O motor O function O of O these O muscles O , O even O though O a O complete O sensory O loss O was O verified O . O This O concurs O with O clinical O observations O of O median O compression O neuropathy O . O Individuals O with O carpal O tunnel O syndrome O complain O of O sensory O dysfunction O early O in O the O disease O process O ( O at O the O beginning O ) O , O while O motor O signs O of O thenar O wasting O and O thumb O weakness O occur O as O the O disease O advances O . O The O concept O that O the O motor O deficit O is O more O resistant O to O peripheral O median O neuropathy O than O sensory O loss O has O been O well O documented O [ O 23 O , O 26 O , O 27 O ] O . O Butterworth O et O al O . O studied O the O temporal O effects O on O sensory O and O motor O blockade O after O injection O of O bupivacaine O or O mepivacaine O , O and O found O that O sensory O loss O was O complete O but O about O a O 20 O % O compound O motor O action O potential O remained O after O 40 O minutes O [ O 23 O ] O . O In O conclusion O , O we O have O incorporated O a O method O for O assessing O thumb O motor O deficit O based O on O strength O measurement O with O a O standard O local O anesthetic O to O investigate O the O effects O of O a O simulated O median O neuropathy O on O thumb O motor O function O . O Median O nerve O block O results O in O force O deficits O in O all O directions O , O with O the O most O severe O impairment O in O abduction O and O flexion O . O Future O endeavors O using O this O methodology O can O potentially O further O elucidate O underlying O pathomechanisms O of O peripheral O neuropathies O in O all O digits O of O the O hand O . O
