Location and properties of respiratory neurones with putative intrinsic bursting properties in the rat in situ (2009)

Using the in situ arterially perfused preparations of both neonatal and juvenile rats, we provide the first description of the location, morphology and transmitter content of a population of respiratory neurones that retains a bursting behaviour after ionotropic receptor blockade. All burster neurones exhibited an inspiratory discharge during eupnoeic respiration. These neurones were predominantly glutamatergic, and were located within a region of the ventral respiratory column that encompasses the pre-Bötzinger complex and the more caudally located ventral respiratory group. Bursting behaviour was both voltage and persistent sodium current dependent and could be stimulated by sodium cyanide to activate this persistent sodium current. The population of burster neurones may overlap with that previously described in the neonatal slice in vitro. Based upon the present and previous findings, we hypothesize that this burster discharge may be released when the brain is subject to severe hypoxia or ischaemia, and that this burster discharge could underlie gasping.
Atmospheric pressure chemical ionization of explosives using alternating current corona discharge ion source (2015)

Ensuring public safety and security in today's mobile society requires robust detection technologies that are field-deployable and offer ever-improving sensitivity and specificity. Atmospheric pressure ionization is well suited to field-based sampling but pumping requirements to offset high gas loads can restrict an instrument's deployability and detection sensitivity. In the Special Feature, Usmanov and co-workers describe improved detection for nitrogen-containing explosive compounds using Atmospheric Pressure Chemical Ionization with an alternating current corona discharge source. An electromolded capillary yields a more stable ac corona allowing it to be positioned within 1mm from the inlet for detection limits in the tens of pg.
Abstract 1328: Exploring the pharmacokinetic-pharmacodynamic relationships of AZD3229, a novel and selective inhibitor of cKIT, in a range of mouse xenograft models of gastrointestinal stromal tumors (2019)

Abstract cKIT belongs a family of transmembrane tyrosine kinase growth factor receptors and gain of function mutations result in constitutive c-KIT activation that provide an important pathogenic role in gastrointestinal stromal tumors (GIST). AZD3229 is a highly potent and selective oral best-in-class KIT inhibitor that is active against a wide spectrum of primary and secondary KIT mutations that are known to confer resistance to standard of care agents. AZD3229 demonstrates rapid, extensive and sustained inhibition of KIT signaling in preclinical xenograft models with KIT primary exon 11 del mutations and primary/secondary ATP-binding pocket mutations (GIST 430/654A and patient-derived xenograft (PDX) model of KIT V654A, HGiXF-106) and A-loop mutations (PDX model of KIT Y823D, HGiXF-105 and Ba/F3 KIT D816H). In these models, AZD3229 results in anti-tumour activity (tumour regressions ranging from -60% to -99 % TGI) when dosed orally up to 20 mg/kg BID. The objective of this PK-PD modeling work was to (1) establish the PK-PD-Efficacy relationship for AZD3229 across the four cell-lines and PDX mouse models tested; (2) to confirm the extent and duration of pKIT inhibition required for optimal efficacy, as defined by tumor regressions. Inhibition of KIT phosphorylation observed with AZD3229 shows a direct relationship to free mouse plasma concentration and an estimated in vivo EC90 was estimated for each model (Ba/F3 D816H = 20 nM; GIST 430/V654A= 43 nM; HGiX-106 = 76 nM; HGiX-105 = 4 nM). No change in the extent of inhibition of KIT phosphorylation was observed on repeat dosing. Optimal efficacy is observed when sustained inhibition of pKIT, &amp;gt;90% is achieved over the dosing interval. Conclusion: Exploring the in vivo activity and PK-PD relationship in multiple cell-line derived xenograft and PDX models harboring different mutations provides a benchmark from which to anchor human dose predictions that partly reflect the spectrum of responses likely to be seen in GIST patients.

Higher Electrical Stimulus Intensities Are Required to Activate Chronically Compressed Nerve Roots (1998)

When instrumentation is placed at spinal levels where there is preexisting chronic lumbosacral radiculopathy, holes and screws may need to be stimulated at higher intensities to exclude pedicular perforation and prevent further iatrogenic nerve root injury.
Inheritance, Biochemical Abnormalities, and Clinical Features of Feline Mucolipidosis II: The First Animal Model of Human I-Cell Disease (2003)

Mucolipidosis II (ML II), also called I-cell disease, is a unique lysosomal storage disease caused by deficient activity of the enzyme N-acetylglucosamine-1-phosphotransferase, which leads to a failure to internalize enzymes into lysosomes. We report on a colony of domestic shorthair cats with ML II that was established from a half-sibling male of an affected cat. Ten male and 9 female kittens out of 89 kittens in 26 litters born to clinically normal parents were affected; this is consistent with an autosomal recessive mode of inheritance. The activities of three lysosomal enzymes from affected kittens, compared to normal adult control cats, were high in serum (11-73 times normal) but low in cultured fibroblasts (9-56% of normal range) that contained inclusion bodies (I-cells), reflecting the unique enzyme defect in ML II. Serum lysosomal enzyme activities of adult obligate carriers were intermediate between normal and affected values. Clinical features in affected kittens were observed from birth and included failure to thrive, behavioral dullness, facial dysmorphia, and ataxia. Radiographic lesions included metaphyseal flaring, radial bowing, joint laxity, and vertebral fusion. In contrast to human ML II, diffuse retinal degeneration leading to blindness by 4 months of age was seen in affected kittens. All clinical signs were progressive and euthanasia or death invariably occurred within the first few days to 7 months of life, often due to upper respiratory disease or cardiac failure. The clinical and radiographic features, lysosomal enzyme activities, and mode of inheritance are homologous with ML II in humans. Feline ML II is currently the only animal model in which to study the pathogenesis of and therapeutic interventions for this unique storage disease.
Dipeptidyl peptidase IV (DP IV) activity in serum and on lymphocytes of MRL/Mp-lpr/lprmice correlates with disease onset (1994)

DP IV (CD26), a serine protease expressed on activated T cells, participates in immune responses in vivo as well as in vitro. We measured cell surface and serum DP IV in mice of the autoimmune MRL/Mp-lpr/lpr (MRL/l) strain, which is characterized by massive T cell proliferation and production of anti-nuclear autoantibodies. The mass of inguinal lymph nodes correlated with serum DP IV activity. Furthermore, serum DP IV activity increased markedly in parallel with the acceleration of lymph node swelling and anti-nDNA antibody production. Serum DP IV activity in 16-week-old MRL/l mice reached levels up to three higher than those in age-matched MRL/Mp- +/+ mice or BALB/c mice. Immunohistochemical staining and flow cytometric analysis identified DV IV on surfaces of lymphocytes from the enlarged lymph nodes of MRL/l mice. Subcutaneous injection of the mechanism-based inhibitor, Pro-boroPro, reduced protease activity in serum and cell suspensions prepared from spleen and lymph nodes, confirming the identity of the enzyme as DP IV. These results indicate that the massively accumulating lymphocytes of MRL/l mice have a property characteristic of activated T cells, although they express little surface CD4 or CD8 and do not produce IL-2. DP IV may participate in the role these cells play in the pathogenesis of MRL/l autoimmune disease.
A novel nuclear receptor/coregulator complex controls C. elegans lipid metabolism, larval development, and aging (2004)

Environmental cues transduced by an endocrine network converge on Caenorhabditis elegans nuclear receptor DAF-12 to mediate arrest at dauer diapause or continuous larval development. In adults, DAF-12 selects long-lived or short-lived modes. How these organismal choices are molecularly specified is unknown. Here we show that coregulator DIN-1 and DAF-12 physically and genetically interact to instruct organismal fates. Homologous to human corepressor SHARP, DIN-1 comes in long (L) and short (S) isoforms, which are nuclear localized but have distinct functions. DIN-1L has embryonic and larval developmental roles. DIN-1S, along with DAF-12, regulates lipid metabolism, larval stage-specific programs, diapause, and longevity. Epistasis experiments reveal that din-1S acts in the dauer pathways downstream of lipophilic hormone, insulin/IGF, and TGFbeta signaling, the same point as daf-12. We propose that the DIN-1S/DAF-12 complex serves as a molecular switch that implements slow life history alternatives in response to diminished hormonal signals.

Malignant rhabdoid-tumor cell line showing neural and smooth-muscle-cell phenotypes (1999)

Malignant rhabdoid tumor (MRT) is a rare and extremely aggressive malignant tumor in childhood. In this study, an MRT cell line, designated KP-MRT-NS, was established from the ascitic fluid taken from an 11-month-old girl, whose tumor had originated from the left kidney. Ultrastructural findings demonstrated the typical aggregation of whorls of intermediate filaments. Chromosome constitution was described as 46, XX, add (10)(q26)[17]/46, idem, dis (1;2)(q22;q31)[3] based on ISCN (1995) and a del (22)(q11.2) was not found in this cell line. The origin of MRT is controversial, various cellular origins having been proposed because of the phenotypic diversity of MRT. Therefore, in this study, to clarify the origin of MRT, the expressions of cytoplasmic proteins including smooth-muscle-specific proteins (alpha-smooth-muscle actin, basic calponin, smooth-muscle-myosin-heavy-chain isoforms of SM1 and SM2) in the primary-MRT tissue and cell line were analyzed. In the primary-tumor tissue, the expressions of neurofilament, vimentin and alpha-smooth-muscle actin were demonstrated by indirect immunofluorescence. In the KP-MRT-NS cell line, the expression of neurofilament, alpha-smooth-muscle actin, basic calponin and smooth-muscle-myosin heavy chain of SM1 and SM2 isoforms was revealed by immunofluorescence, Western blot and/or reverse transcriptase-polymerase chain reaction (RT-PCR). MyoD1 mRNA, determined as a skeletal-muscle-cell lineage marker, was not expressed in the primary-tumor tissue or in the KP-MRT-NS cell line. According to our findings, the MRT cells are of both neural and smooth-muscle cell phenotypes, and support the neural-crest origin of MRT.
HER2-targeted therapy influences CTC status in metastatic breast cancer (2020)

HER2-targeted therapy seems to reduce the overall CTC count in patients with MBC. This should be taken into account when CTC status is used as an indicator for aggressive or indolent metastatic tumor disease.
Dietary perturbation of calcium metabolism in normal man: compartmental analysis (1969)

The effect of dietary calcium intake on calcium metabolism was studied in eight normal volunteers by multicompartmental analysis of radiocalcium and balance data. In paired studies of six normal subjects on normal and high or low calcium intakes, necessary and sufficient criteria were used to determine changes in calcium metabolic parameters produced by alterations in dietary calcium. These changes involved gastrointestinal calcium absorption rate, renal and endogenous fecal rate constants, and bone resorption rate. Bone accretion rate and compartment sizes need not change between the paired studies. The changes of parameters involving kidney, gut, and bone were in a direction to support calcium homeostasis and were compatible with the pattern of changes produced by parathyroid hormone. However, the source of the stimulus for hormone secretion was not apparent since plasma calcium concentrations showed no significant difference between paired studies. The implications of these findings relative to control of hormone secretion, calcium regulatory mechanisms, and metabolic bone disease are discussed.
201 Comparative Evaluation of Percutaneous Radiofrequency Rhizotomy, Stereotactic Radiosurgery and Microvascular Decompression in the Management of Refractory Trigeminal Neuralgia (2012)

INTRODUCTION: Choosing the optimal treatment modality for refractory trigeminal neuralgia (TN) is multifactorial, and has not been well defined in the literature. In this review we specifically explore the role of three factors in determining the treatment modality: age, recurrence rate, and cost. METHODS: Retrospective chart review of patients who underwent percutaneous Radiofrequency Rhizotomy (RFR), Stereotactic Radiosurgery (SRS) and Microvascular Decompressions (MVD) for trigeminal neuralgia between the periods of 2003 to 2011. RESULTS: A total of 95 procedures were identified, including 46 MVDs, 27 RFR, and 22 SRS. The average age of patients who had: (1) MVD was 52 ± 12 (24-75), (2) SRS was 67 ± 15 (25-85), and (3) RFR was 71 ± 11 (51-89). Preliminary results suggest recurrence of symptoms in 3/46 patients treated with MVD, 3/21 treated with RF, and none in the patients initially treated with SRS. The total charges for the 3 procedures were (mean ± SD): 56 ± 2.5 × 1000, 1.3 ± 0.8 × 1000, and 44 ± 1.6 × 1000 US dollars, for MVD, RS, and SRS respectively. Actual payments varied depending on health insurance coverage. CONCLUSION: Despite their unique advantages, the charges for the three procedures vary considerably. MVD was the most expensive procedure, and was least likely associated with facial numbness. SRS and RFR were recommended for older patients. SRS is expensive, and requires several weeks before symptomatic improvement. RFR is associated with immediate response, performed as an outpatient, and is the cheapest of the three procedures; however it is associated with the highest rate of recurrence.
Effect of Dietary Starch, Fat, and Bicarbonate Content on Exercise Responses and Serum Creatine Kinase Activity in Equine Recurrent Exertional Rhabdomyolysis (2003)

To determine the effect of dietary starch, bicarbonate, and fat content on metabolic responses and serum creatine kinase (CK) activity in exercising Thoroughbreds with recurrent exertional rhabdomyolysis (RER), 5 RER horses were fed 3 isocaloric diets (28.8 Mcal/d [120.5 MJ/d]) for 3 weeks in a crossover design and exercised for 30 minutes on a treadmill 5 days/wk. On the last day of each diet, an incremental standardized exercise test (SET) was performed. The starch diet contained 40% digestible energy (DE) as starch and 5% as fat: the bicarbonate-starch diet was identical but was supplemented with sodium bicarbonate (4.2% of the pellet): and the fat diet provided 7% DE as starch and 20% as fat. Serum CK activity before the SET was similar among the diets. Serum CK activity (log transformed) after submaximal exercise differed dramatically among the diets and was greatest on the bicarbonate-starch diet (6.51 +/- 1.5) and lowest on the fat diet (5.71 +/- 0.6). Appreciable differences were observed in the severity of RER among individual horses. Postexercise plasma pH, bicarbonate concentration, and lactate concentration did not differ among the diets. Resting heart rates before the SET were markedly lower on the fat diet than on the starch diet. Muscle lactate and glycogen concentrations before and after the SET did not differ markedly among the diets. A high-fat, low-starch diet results in dramatically lower postexercise CK activity in severely affected RER horses than does a low-fat, high-starch diet without measurably altering muscle lactate and glycogen concentrations. Dietary bicarbonate supplementation at the concentration administered in this study did not prevent increased serum CK activity on a high-starch diet.
Renin Response to 12-Hydroxyeicosatetraenoic Acid Is Increased in Diabetic Rats (1995)

Eicosanoids (prostaglandins) can alter renin secretion and angiotensin (ANG) II action. We have studied the effects of both prostacyclin and a lipoxygenase (LO) product, 12-hydroxyeicosatetraenoic acid (12-HETE), on renin in normal and streptozotocin-induced diabetic rats. 12-HETE is not only a potent inhibitor of basal renin secretion but also a key mediator of ANG II-induced renin inhibition. We have also examined the effects of ANG II on 12-HETE formation in normal and diabetic animals. Both plasma (3.9 +/- 0.9 vs. 0.8 +/- 0.1 ng ANG I.ml-1.h-1, P < 0.01) and tissue (38 +/- 6 vs. 21 +/- 2 ng ANG I.mg tissue-1.h-1, P < 0.05) renin activity levels were markedly reduced in diabetic animals. Iloprost (10(-6) mol/l), a stable analog of prostacyclin, had similar stimulatory effects on renin secretion in both normal and diabetic tissues, but the response was enhanced by LO inhibition in diabetic tissue. 12-HETE (10(-7) mol/l) had an exaggerated effect on renin inhibition in diabetic tissue (78 +/- 2% normal vs. 65 +/- 4% diabetic, P < 0.05). Similarly, ANG II (10(-8) mol/l) inhibition of renin was significantly enhanced in diabetic rats (P < 0.001). However, ANG II did not produce an exaggerated increase in 12-HETE in diabetic renal tissue. Insulin reversed the inhibitory effects of ANG II on renin in normal rats, but it blunted the effect of ANG II in diabetic rats. These studies suggest that, while the capacity of renal cortical tissue to synthesize 12-HETE in response to ANG II is not altered, 12-HETE and ANG II actions are exaggerated in diabetes, and this may contribute to reduced renin production.
[Effects of porcelain fused to metal on the accuracy of fit of various alloys]. (1991)

One high gold and five low gold porcelain bonding alloys were examined for dimensional changes after fusion of the porcelain. With the same processing techniques applied, the individual firings resulted in varying changes in the accuracy of fit of the tested alloys. Averaging at -0.09 mm Bond-on 4 showed the greatest marginal discrepancies and this was the only alloy that displayed a statistically significant difference to Degudent U.
The helicase Ded1p controls use of near-cognate translation initiation codons in 5' UTRs. (2018)

The conserved and essential DEAD-box RNA helicase Ded1p from yeast and its mammalian orthologue DDX3 are critical for the initiation of translation1. Mutations in DDX3 are linked to tumorigenesis2-4 and intellectual disability5, and the enzyme is targeted by a range of viruses6. How Ded1p and its orthologues engage RNAs during the initiation of translation is unknown. Here we show, by integrating transcriptome-wide analyses of translation, RNA structure and Ded1p-RNA binding, that the effects of Ded1p on the initiation of translation are connected to near-cognate initiation codons in 5' untranslated regions. Ded1p associates with the translation pre-initiation complex at the mRNA entry channel and repressing the activity of Ded1p leads to the accumulation of RNA structure in 5' untranslated regions, the initiation of translation from near-cognate start codons immediately upstream of these structures and decreased protein synthesis from the corresponding main open reading frames. The data reveal a program for the regulation of translation that links Ded1p, the activation of near-cognate start codons and mRNA structure. This program has a role in meiosis, in which a marked decrease in the levels of Ded1p is accompanied by the activation of the alternative translation initiation sites that are seen when the activity of Ded1p is repressed. Our observations indicate that Ded1p affects translation initiation by controlling the use of near-cognate initiation codons that are proximal to mRNA structure in 5' untranslated regions.
Multimodal Diaries (2007)

Time management is an important aspect of a successful professional life. In order to have a better understanding of where our time goes, we propose a system that summarizes the user's daily activity (e.g. sleeping, walking, working on the pc, talking, ...) using all-day multimodal data recordings. Two main novelties are proposed: (i) a system that combines both physical and contextual awareness hardware and software. It records synchronized audio, video, body sensors, GPS and computer monitoring data. (ii) A semi-supervised temporal clustering (SSTC) algorithm that accurately and efficiently groups large amounts of multimodal data into different activities. The effectiveness and accuracy of our SSTC is demonstrated in synthetic and real examples of activity segmentation from multimodal data gathered over long periods of time.
Ability of 3 Different Meningococcal C Conjugate Vaccines to Induce Immunologic Memory after a Single Dose in UK Toddlers (2001)

To test for immunologic memory after a single dose of meningococcal C conjugate (MCC) vaccine in toddlers, 226 children 12-18 months old were randomized to receive 1 of 3 MCC vaccines, with a C polysaccharide booster 6 months later. The protein conjugate was diphtheria mutant toxoid in 2 vaccines (MCC-CRM(197)) and was tetanus toxoid in the third (MCC-TT). One month after the MCC vaccines, 91%-100% of children had serum bactericidal antibody (SBA) titers > or =8, and 89%-100% had a > or =4-fold increase. Geometric mean titer (GMT) increased from <4 to 215 (95% confidence interval [CI], 166-279). MCC-TT induced higher SBA GMTs (P<.001) and higher proportions with SBA > or =8 (P=.02) than did the MCC-CRM(197) vaccines. By 6 months, GMTs had decreased to 55.1 (95% CI, 40-76), but IgG antibody avidity increased (P<.001). Induction of immunologic memory was confirmed by a GMT of 1977 (range, 1535-2547) after the polysaccharide booster and a further increase in avidity. This evidence justified the use of a single dose in a catch-up immunization program for children 1-18 years old.
