Taken together, these data establish that BCAR3 functions as a positive regulator of cytoskeletal remodeling and adhesion turnover in invasive breast cancer cells through its ability to influence the balance between Rac1 and RhoA signaling. Considering that BCAR3 protein levels are elevated in advanced breast cancer cell lines and enhance breast cancer cell motility, we propose that BCAR3 functions in the transition to advanced disease by triggering intracellular signaling events that are essential to the metastatic process." ], "offsets": [ [ 161, 1739 ] ] } ]

Resveratrol improves non-alcoholic fatty liver disease by activating AMP-activated protein kinase. AIM: To investigate whether resveratrol (RSV) can improve non-alcoholic fatty liver disease (NAFLD) and to find the possible mechanism. METHODS: Rats fed a high-fat diet were treated with RSV. The liver histology was observed. Hyperinsulinemic euglycemic clamp was performed to assess insulin sensitivity. Fat accumulation was induced in HepG2 cells, and the cells were treated with RSV. AMP-activated protein kinase (AMPK) phosphorylation levels were determined both in the animal study and cell study. RESULTS: Rats fed a high-fat diet developed abdominal obesity, NAFLD, and insulin resistance (IR), which were markedly improved by 10 weeks of RSV administration. RSV treatment prevented triacylglycerol (TG) accumulation in HepG2 cells that were incubated with high concentration of glucose and insulin. Both in vivo and in vitro studies showed that RSV treatment could promote the phosphorylation of AMPK, which in this study, suppressed 2 lipogenesis gene expressions, contributing to the improvement of NAFLD and IR. CONCLUSION: The results indicated that by reducing TG accumulation and improving IR, RSV could protect the liver from NAFLD. The activation of AMPK was involved in the mechanism. RSV has the therapeutic potential for preventing or treating NAFLD and IR-related metabolic disorders.

Based on the results of earlier research we hypothesized that Tourette syndrome patients might employ altered control mechanisms of attentional processes and have concurrent difficulties in allocating their attentional resources among competing tasks. Event-related brain potentials (ERPs) were recorded in a group of Tourette syndrome patients and in a matched control group during a dual task experiment. This experiment required the simultaneous detection of visual and auditory target stimuli which were manipulated to yield two different difficulty levels each of which were varied orthogonally. The behavioural parameters confirmed the intended performance differences between difficult-to-detect targets and easy-to-detect targets. This was paralleled by lower amplitudes and longer latencies of the corresponding P3b-ERP subcomponents. Although Tourette syndrome patients were unimpaired in overall performance they showed an increased interference of visual task demands with auditory target perception. In parallel they also exhibited a reduced amplitude of the P3b component to auditory targets.

Electrophysiological measures and dual-task performance in Tourette syndrome indicate deficient divided attention mechanisms. Tourette syndrome has been associated with impairments of attentional functions such as distractability, even in subjects without co-morbid attention deficit hyperactivity disorder. Based on the results of earlier research we hypothesized that Tourette syndrome patients might employ altered control mechanisms of attentional processes and have concurrent difficulties in allocating their attentional resources among competing tasks. Event-related brain potentials (ERPs) were recorded in a group of Tourette syndrome patients and in a matched control group during a dual task experiment. This experiment required the simultaneous detection of visual and auditory target stimuli which were manipulated to yield two different difficulty levels each of which were varied orthogonally. The behavioural parameters confirmed the intended performance differences between difficult-to-detect targets and easy-to-detect targets. This was paralleled by lower amplitudes and longer latencies of the corresponding P3b-ERP subcomponents. Although Tourette syndrome patients were unimpaired in overall performance they showed an increased interference of visual task demands with auditory target perception. In parallel they also exhibited a reduced amplitude of the P3b component to auditory targets. The findings show that Tourette syndrome patients are not generally impaired in their dual task performance. The allocation of attentional resources to competing tasks however, is altered. We speculate that this may be related to deficient inhibitory functions.

The NOD mouse model has clinical and histoimmunological features similar to those of human insulin-dependent diabetes mellitus (IDDM). The SEB- and LPS-treated BALB/c mouse models exhibit pathogenic similarities with human septic shock conditions. In the NOD mouse, fusidin suppressed the spontaneous development of insulitis (mean inhibition 73%) and hyperglycaemia (IDDM incidence 25% versus 0%) when administered at 40 mg/kg five times weekly for 8 consecutive weeks from the fourth week of age; concurrently treated animals exhibited reduced percentages of splenic T lymphocytes. This anti-diabetogenic effect was confirmed in the accelerated model of diabetes induced in the NOD mouse with cyclophosphamide (CY) (IDDM incidence 55% versus 21-6% using dosages of fusidin from 40 to 80 mg/kg five times weekly); protection from IDDM development was achieved even when the drug (80 mg/kg/day) was first administered 7 days after CY challenge. In contrast, fusidin did not reverse hyperglycaemia when administered to CY-treated animals within 3 days of IDDM development. In the two models of septic shock, prophylactic treatment with fusidin, 80 mg/kg given three times for 2 days prior to D-Gal/SEB or D-Gal/LPS challenge, drastically reduced the lethality compared with D-Gal/buffer-treated mice. This effect may depend on the inhibitory action of fusidin on the secretion of cytokines such as interferon-gamma and tumour necrosis factor-alpha, the serum levels of which were greatly diminished in the fusidin-treated mice (mean inhibition 50-90%). These results demonstrate that fusidin may have a role in the treatment of cell-mediated autoimmune diseases and cytokine-mediated infectious diseases in humans." ], "offsets": [ [ 101, 2148 ] ] } ]

Effects of sodium fusidate in animal models of insulin-dependent diabetes mellitus and septic shock. We have evaluated the effects of the novel immunosuppressant sodium fusidate (fusidin) in the non-obese diabetic (NOD) mouse and in D-galactosamine (D-Gal)-presensitized BALB/c mice challenged with the bacterial superantigen, Staphylococcus aureus enterotoxin B (SEB) or with the endotoxin, Escherichia coli lipopolysaccharide (LPS). The NOD mouse model has clinical and histoimmunological features similar to those of human insulin-dependent diabetes mellitus (IDDM). The SEB- and LPS-treated BALB/c mouse models exhibit pathogenic similarities with human septic shock conditions. In the NOD mouse, fusidin suppressed the spontaneous development of insulitis (mean inhibition 73%) and hyperglycaemia (IDDM incidence 25% versus 0%) when administered at 40 mg/kg five times weekly for 8 consecutive weeks from the fourth week of age; concurrently treated animals exhibited reduced percentages of splenic T lymphocytes. This anti-diabetogenic effect was confirmed in the accelerated model of diabetes induced in the NOD mouse with cyclophosphamide (CY) (IDDM incidence 55% versus 21-6% using dosages of fusidin from 40 to 80 mg/kg five times weekly); protection from IDDM development was achieved even when the drug (80 mg/kg/day) was first administered 7 days after CY challenge. In contrast, fusidin did not reverse hyperglycaemia when administered to CY-treated animals within 3 days of IDDM development. In the two models of septic shock, prophylactic treatment with fusidin, 80 mg/kg given three times for 2 days prior to D-Gal/SEB or D-Gal/LPS challenge, drastically reduced the lethality compared with D-Gal/buffer-treated mice. This effect may depend on the inhibitory action of fusidin on the secretion of cytokines such as interferon-gamma and tumour necrosis factor-alpha, the serum levels of which were greatly diminished in the fusidin-treated mice (mean inhibition 50-90%). These results demonstrate that fusidin may have a role in the treatment of cell-mediated autoimmune diseases and cytokine-mediated infectious diseases in humans.

METHODS: A systematic computer-aided search of the Medline, PsyclInfo, and Embase database. A rating system was used to assess the strength of the evidence, based on the methodologic quality of the randomized controlled trials, the relevance of the outcome measures, and the consistency of the results. RESULTS: Eleven randomized controlled trials were selected, including seven trials of high methodologic quality, as well as one parallel group controlled survey and one longitudinal study. Only three of the seven high-quality studies showed favorable results for information. There is strong evidence that a booklet increases knowledge and moderate evidence that physician-related cues increase the confidence in a booklet and adherence to exercises. There is limited evidence that a biopsychosocial booklet is more efficient than a biomedical booklet to shift patient's beliefs about physical activity, pain, and consequences of low back trouble. There is strong evidence that booklets are not efficient on absenteeism and conflicting evidence that they are efficient on healthcare use. There is no evidence that e-mail discussion or video programs alone are effective to reduce low back pain, disability, and healthcare costs. CONCLUSIONS: Information based on a biopsychosocial model is recommended in primary care to shift patient beliefs on low back pain.

Information and low back pain management: a systematic review. STUDY DESIGN: A systematic search of three electronic databases was done to identify randomized controlled trials on the effect of written or audiovisual information in low back pain.

The scrotal myocutaneous flap. The scrotum is a thermoregulatory, well-vascularized structure formed by skin and nonstriated muscle with unique elastic properties. This makes it an ideal source of tissue coverage for problem wounds in its vicinity. Two patients in which scrotal musculocutaneous flaps were used are reported: one, a paraplegic, with a recurrent ischioperineal decubitus ulcer, and another with an ulcer of the penis with exposed Dacron graft previously placed to treat Peyronie's disease. After reviewing the anatomy of the scrotum and the existent literature, we studied scrotal vascularity in a fresh specimen by transillumination.

SOURCES: Review of the literature using the MEDLINE database and review of the experience in pediatric intensive care units. SUMMARY OF THE FINDINGS: The continuous administration of analgesics and sedatives prevents the development of undersedation and is less demanding in terms of care than intermittent administration. Midazolam is the most commonly used drug for continuous sedation of critically ill children. Opioid derivatives and nonsteroidal anti-inflammatory drugs are the most widely used analgesics in critically ill children. Opioids combined with benzodiazepines, given in continuous infusion, are the drugs of choice in mechanically ventilated children, especially morphine and fentanyl. The use of protocols and monitoring through clinical scores and objective methods (e.g. bispectral index) allow adjusting medication more appropriately, preventing oversedation, undersedation, and the withdrawal syndrome. Non-pharmacological interventions, such as music therapy, noise control, adequate use of light, massage, conversation with the patient, are ancillary measures that help children to adapt to the adverse hospital environment.

Analgesia and sedation in children: practical approach for the most frequent situations. OBJECTIVES: To review the most frequent recommendations, doses and routes of administration of sedatives, analgesics, and muscle relaxants in children, as well as the methods for monitoring the level of sedation. SOURCES: Review of the literature using the MEDLINE database and review of the experience in pediatric intensive care units. SUMMARY OF THE FINDINGS: The continuous administration of analgesics and sedatives prevents the development of undersedation and is less demanding in terms of care than intermittent administration. Midazolam is the most commonly used drug for continuous sedation of critically ill children. Opioid derivatives and nonsteroidal anti-inflammatory drugs are the most widely used analgesics in critically ill children. Opioids combined with benzodiazepines, given in continuous infusion, are the drugs of choice in mechanically ventilated children, especially morphine and fentanyl. The use of protocols and monitoring through clinical scores and objective methods (e.g. bispectral index) allow adjusting medication more appropriately, preventing oversedation, undersedation, and the withdrawal syndrome. Non-pharmacological interventions, such as music therapy, noise control, adequate use of light, massage, conversation with the patient, are ancillary measures that help children to adapt to the adverse hospital environment. CONCLUSIONS: Sedation should be tailored to each child for each specific situation. Protocols that facilitate the correct selection of drugs, their appropriate administration and careful monitoring improve the quality of sedation and analgesia and avoid their adverse effects.

METHODS: The COH model (Kunming breed) was induced by injecting mice with pregnant mare serum gonadotrophin (0.4 IU/g) and human chorionic gonadotropin (1 IU/g), followed by treatment with BSHXR at three different concentrations (5.7, 11.4, and 22.8 g/kg), Bushen recipe (BSR) (5.7 g/kg), and Huoxue recipe (HXR) (5.7 g/kg). After successful mating, the pregnancy rate and implantation sites were examined on embryo day 8 (ED8), and the weight ratio of endometrium was calculated on ED4 midnight. Serum estrogen, progesterone, and endometrial PGE2 levels were measured using enzyme-linked immunosorbent assay. The endometrial microvasculature was evaluated using CD31 immunostaining. The protein and mRNA levels of the angiogenic factors in the endometrium were evaluated using western blot, immunohistochemistry, and polymerase chain reaction. RESULTS: In the COH group, the pregnancy rate and implantation sites were significantly decreased, and abnormal serum hormone levels and impaired endometrial vascular development were observed. After BSHXR treatment, the supraphysiological serum progesterone level in COH mice was restored to normalcy. Moreover, the abnormal expression of the endometrial pro-angiogenic factors, including HIF1alpha, COX2-PGE2 pathway, and the down-stream factors, namely, MMP2, MMP9, TIMP2, and FGF2 after subjecting mice to COH was significantly improved after BSHXR treatment. CONCLUSION: BSHXR could improve embryo implantation by regulating hormonal balance and modulating endometrial angiogenesis in mice, without inducing any side effects in normal pregnancy." ], "offsets": [ [ 120, 2158 ] ] } ]

Application of acetylcholine (ACh) during this catecholamine-induced response caused a repolarization, and removal of ACh induced a transient enhancement in the depolarization (rebound). These effects of ACh were abolished by atropine. Application of ACh alone and its removal had little effect on the membrane potential.

Adrenergic-cholinergic interactions on membrane potential of K+ -depolarized ventricular muscle. In guinea pig ventricular muscles exposed to K+-rich (27 mM) Tyrode solution containing 0.2 mM Ba, catecholamine elicited a slight depolarization of the resting membrane. Application of acetylcholine (ACh) during this catecholamine-induced response caused a repolarization, and removal of ACh induced a transient enhancement in the depolarization (rebound). These effects of ACh were abolished by atropine. Application of ACh alone and its removal had little effect on the membrane potential. Like the catecholamine-induced depolarization, the rebound depolarization after ACh removal was inhibited by slow channel blockers. Thus the rebound was attributed at least in part to enhanced changes in the catecholamine-sensitive conductance, i.e., a beta-receptor-mediated increase in the slow channel conductance. In driven muscles perfused with normal Tyrode solution, there was a rebound increase in twitch tension when ACh was removed in the presence of catecholamine, and this rebound was accompanied by an "extra" elevation of the action potential plateau. Thus cessation of the stimulation of myocardial muscarinic receptors may transiently lead to an enhanced activity of the beta-adrenoceptor-slow channel system in guinea pig ventricular muscle.

In this work we studied the effect of ionic strength of the incubation medium on the kinetics of the processes that accompany Ca2+-dependent induction of the mitochondrial pore by fatty acid: organelle swelling, Ca2+ release from the matrix, changes in transmembrane potential (Deltapsi) and rate of oxygen consumption, and the release of cytochrome c from the intermembrane space. Two basic incubation media were used: sucrose medium and isotonic ionic medium containing KCl without sucrose. We found that 200 muM Ca2+ and 20 muM HDA in the presence of CsA effectively induce high-amplitude swelling of mitochondria both in the case of sucrose and in the ionic incubation medium. In the presence of CsA, mitochondria can rapidly absorb Ca2+ and retain it in the matrix for a while without reducing Deltapsi. Upon incubation in the ionic medium, mitochondria retain most of the added Ca2+ in the matrix for a short time without reducing the Deltapsi. In both cases the addition of HDA to the mitochondria 2 min after the introduction of Ca2+ leads to the rapid release of these ions from the matrix and total drop in Deltapsi. The mitochondrial swelling induced by Ca2+ and HDA in non-ionic medium is accompanied by almost maximal stimulation of respiration. Under the same conditions, but during incubation of mitochondria in the ionic medium, it is necessary to add cytochrome c for significant stimulation of respiration. The mitochondrial swelling induced by Ca2+ and HDA leads to the release of cytochrome c in a larger amount in the case of ionic medium than for the sucrose medium. We conclude that high ionic strength of the incubation medium determines the massive release of cytochrome c from mitochondria and liberates it from the respiratory chain, which leads to blockade of electron transport along the respiratory chain and consequently to disruption of the energy functions of the organelles." ], "offsets": [ [ 220, 2349 ] ] } ]

Induction of Ca2+-dependent cyclosporin A-insensitive nonspecific permeability of the inner membrane of liver mitochondria and cytochrome c release by alpha,omega-hexadecanedioic acid in media of varying ionic strength. In liver mitochondria loaded with Ca2+ or Sr(2+), alpha,omega-hexadecanedioic acid (HDA) can induce nonspecific permeability of the inner membrane (mitochondrial pore) by the mechanism insensitive to cyclosporin A (CsA). In this work we studied the effect of ionic strength of the incubation medium on the kinetics of the processes that accompany Ca2+-dependent induction of the mitochondrial pore by fatty acid: organelle swelling, Ca2+ release from the matrix, changes in transmembrane potential (Deltapsi) and rate of oxygen consumption, and the release of cytochrome c from the intermembrane space. Two basic incubation media were used: sucrose medium and isotonic ionic medium containing KCl without sucrose. We found that 200 muM Ca2+ and 20 muM HDA in the presence of CsA effectively induce high-amplitude swelling of mitochondria both in the case of sucrose and in the ionic incubation medium. In the presence of CsA, mitochondria can rapidly absorb Ca2+ and retain it in the matrix for a while without reducing Deltapsi. Upon incubation in the ionic medium, mitochondria retain most of the added Ca2+ in the matrix for a short time without reducing the Deltapsi. In both cases the addition of HDA to the mitochondria 2 min after the introduction of Ca2+ leads to the rapid release of these ions from the matrix and total drop in Deltapsi. The mitochondrial swelling induced by Ca2+ and HDA in non-ionic medium is accompanied by almost maximal stimulation of respiration. Under the same conditions, but during incubation of mitochondria in the ionic medium, it is necessary to add cytochrome c for significant stimulation of respiration. The mitochondrial swelling induced by Ca2+ and HDA leads to the release of cytochrome c in a larger amount in the case of ionic medium than for the sucrose medium. We conclude that high ionic strength of the incubation medium determines the massive release of cytochrome c from mitochondria and liberates it from the respiratory chain, which leads to blockade of electron transport along the respiratory chain and consequently to disruption of the energy functions of the organelles.

We found that MHY2245 exhibited potent cytotoxicity to SKOV3 cells in a time- and concentration-dependent manner. The cytotoxicity of MHY2245 (IC50=0.32 microM) was higher than that of doxorubicin (DOX, IC50=1.38microM) against SKOV3 cells. MHY2245 significantly inhibited SIRT1 enzyme activity, reduced the expression of SIRT1, increased cell cycle arrest at G2/M phase, and induced apoptotic cell death in SKOV3 cells via expression of cytochrome c, cleaved-PARP, cleaved caspase-3, and Bax. This might be associated with blocking of the pyruvate kinase M2 (PKM2)/mTOR pathway. MHY2245 also inhibited tumor growth and reduced tumor size when SKOV3 cells were transplanted into nude mice. Our results indicate that MHY2245 exerts antitumor activity against ovarian cancer cells by blocking the PKM2/mTOR pathway.

The aim of the present study was to investigate the antitumor activity of MHY2245, a new synthetic SIRT inhibitor, on human ovarian cancer cells. We found that MHY2245 exhibited potent cytotoxicity to SKOV3 cells in a time- and concentration-dependent manner. The cytotoxicity of MHY2245 (IC50=0.32 microM) was higher than that of doxorubicin (DOX, IC50=1.38microM) against SKOV3 cells. MHY2245 significantly inhibited SIRT1 enzyme activity, reduced the expression of SIRT1, increased cell cycle arrest at G2/M phase, and induced apoptotic cell death in SKOV3 cells via expression of cytochrome c, cleaved-PARP, cleaved caspase-3, and Bax. This might be associated with blocking of the pyruvate kinase M2 (PKM2)/mTOR pathway. MHY2245 also inhibited tumor growth and reduced tumor size when SKOV3 cells were transplanted into nude mice. Our results indicate that MHY2245 exerts antitumor activity against ovarian cancer cells by blocking the PKM2/mTOR pathway. We suggest that MHY2245 is a promising anticancer agent that disrupts ovarian cancer cell metabolism.

Molecular mechanisms of mistletoe plant extract-induced apoptosis in acute lymphoblastic leukemia in vivo and in vitro. Viscum album (Mistletoe) is one of the most widely used alternative cancer therapies. Aqueous mistletoe extracts (MT) contain the three mistletoe lectins I, II and III as one predominant group of biologically active agents. Although MT is widely used, there is a lack of scientifically sound preclinical and clinical data. In this paper, we describe for the first time the in vivo efficacy and mechanism of action of MT in lymphoblastic leukemia. For this purpose, we first investigated both the cytotoxic effect and the mechanism of action of two standardized aqueous MTs (MT obtained from fir trees (MT-A); MT obtained from pine trees (MT-P)) in a human acute lymphoblastic leukemia (ALL) cell line (NALM-6).

METHODS: Fifteen patients (six men and nine women; mean age: 65 years; range: 48-83 years) with advanced Kienbock's disease, who underwent arthroscopic lunate resection between April 2008 and March 2016, were reviewed clinically and radiographically after a follow-up of >2 years (mean: 29 months; range: 24-60 months). Clinical parameters, such as wrist range of motion, grip strength, Disabilities of the Arm, Shoulder, and Hand (DASH) score, and patient-rated wrist evaluation (PRWE) score were evaluated. Radiographic parameters included radioscaphoid angle, scaphocapitate angle, carpal height ratio, ulnar-triquetrum distance, and the scaphoid-triquetrum distance. Wilcoxon's signed-rank test was used to compare measurement results. RESULTS: During the final follow-up, patients exhibited significant improvements, such as 42.9 in wrist range of motion (P = .009), 24.5% of the contralateral side in grip strength (P = .001), 26.2 points in DASH score (P = .002), and 37.8 points in PRWE score (P < .001), compared with the preoperative values.

CONCLUSIONS: Our results suggest that arthroscopic lunate excisions provided excellent postoperative pain relief and functional recovery within 2 years of follow-up. Changes in carpal alignment and stress concentration on the radial side of the carpal bones could occur in the long term; however, arthroscopic lunate excision can be a good surgical option for treating low-demand patients with advanced Kienbock's disease.

Human liver chimeric mice provide a model for hepatitis B and C virus infection and treatment. A paucity of versatile small animal models of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection has been an impediment to both furthering understanding of virus biology and testing antiviral therapies. We recently described a regulatable system for repopulating the liver of immunodeficient mice (specifically mice lacking fumaryl acetoacetate hydrolase [Fah], recombination activating gene 2 [Rag2], and the gamma-chain of the receptor for IL-2 [Il-2rgamma]) with human hepatocytes. Here we have shown that a high transplantation dose (3 x 106 to 5 x 106 human hepatocytes/mouse) generates a higher rate of liver chimerism than was previously obtained in these mice, up to 95% human hepatocyte chimerism. Mice with a high level of human liver chimerism propagated both HBV and HCV, and the HCV-infected mice were responsive to antiviral treatment. This human liver chimeric mouse model will expand the experimental possibilities for studying HBV and HCV infection, and possibly other human hepatotropic pathogens, and prove useful for antiviral drug testing.

[Study on hyperspectral characteristics of apple florescence canopy]. The present study aims to systematically analyze the hyperspectral characteristics of apple florescence canopy and explore the sensitive spectra to provide the theoretical basis for large area apple information extracting and remote sensing retrieval for nutrition diagnosis. Based on the 120 hyperspectral data of apple florescence canopy acquired with ASD Field Spec 3 portable object spectrometer, the effects of different sample numbers on hyperspectral characteristics were analyzed. Using variance analysis method, the hyperspectral characteristics of apple florescence canopy and the sensitive wave bands were obtained. The results showed that with the increase in cumulative sample numbers, the hyperspectrum curves of apple florescence became stable and smooth. At the 550 nm green peak and the 760-1,300 nm reflection plateau, the reflection rate reduced with the increase in flowering amount, while in the red valley of 670 nm, the reflection rate increased with the increase in flowering amount; At the wave bands of 350-500, 600-680 and 760-1,300 nm, the variance analysis results showed very significant differences, indicating that they were sensitive wave bands of florescence canopy.

The influence of emotions on inhibitory functioning in borderline personality disorder. BACKGROUND: Borderline personality disorder (BPD) is characterized by an emotionally unstable and impulsive cognitive and behavioral style. Inhibitory dysfunction has been hypothesized as playing a crucial role in BPD psychopathology. This study aimed to systematically investigate differential inhibitory functions in patients with BPD as compared to healthy controls, and to investigate their expected impairment in the context of aversive emotions by comparing performances in neuropsychological tasks that present both neutral and emotional material. METHOD: Unmedicated female patients with BPD (n=28) were compared with age-matched healthy female controls (n=30) in the following tasks: the emotional Stroop test (inhibition of interference), directed forgetting (intentional, resource-dependent inhibition), and an emotional variant of the negative priming task (automatic, resource-independent inhibition). RESULTS: In comparison with the controls, the BPD patients showed reduced inhibition of negative material in the directed forgetting task and in the negative priming task. No effect was found in the emotional Stroop test. Significant correlations with current affect as well as trait anxiety and anger (but not impulsiveness) were found in the BPD group specifically for negative stimuli, while no such correlations were found in the control group. In addition to inhibitory deficiencies, BPD patients had difficulties remembering positive words in the directed forgetting task. CONCLUSIONS: Our data suggest that individuals with BPD have difficulties in actively suppressing irrelevant information when it is of an aversive nature. Inhibitory dysfunction appears to be closely related to state and trait variables of unstable affect, but not to self-reported impulsiveness.

Little is known about the specific molecular events which are responsible for this increase in uptake. Therefore, we investigated whether myocardial ischemia induces the gene expression of the major cardiac facilitative glucose transporters, GLUT4 and GLUT1. We determined the expression of myocardial glucose transporter mRNAs and polypeptides after 6 h of regional ischemia in a dog model by semi-quantitative Northern blotting and immunoblotting. GLUT1 but not GLUT4 expression was significantly increased in both ischemic and non-ischemic regions from the experimental hearts when compared to surgical control and normal hearts. GLUT1 mRNA expression was increased 3.4-fold and GLUT1 polypeptide expression was increased 1.7-fold in ischemic hearts when compared to normal or surgical-control hearts. There were no significant regional differences in GLUT1 expression in either normal or ischemic hearts. However, there was a tendency for GLUT1 mRNA expression to be highest in the non-ischemic regions from the 6-h ischemia hearts.

Persistent myocardial ischemia increases GLUT1 glucose transporter expression in both ischemic and non-ischemic heart regions. Persistently ischemic myocardium exhibits increased glucose uptake which may contribute to the preservation of myocardial function and viability. Little is known about the specific molecular events which are responsible for this increase in uptake. Therefore, we investigated whether myocardial ischemia induces the gene expression of the major cardiac facilitative glucose transporters, GLUT4 and GLUT1. We determined the expression of myocardial glucose transporter mRNAs and polypeptides after 6 h of regional ischemia in a dog model by semi-quantitative Northern blotting and immunoblotting. GLUT1 but not GLUT4 expression was significantly increased in both ischemic and non-ischemic regions from the experimental hearts when compared to surgical control and normal hearts. GLUT1 mRNA expression was increased 3.4-fold and GLUT1 polypeptide expression was increased 1.7-fold in ischemic hearts when compared to normal or surgical-control hearts. There were no significant regional differences in GLUT1 expression in either normal or ischemic hearts. However, there was a tendency for GLUT1 mRNA expression to be highest in the non-ischemic regions from the 6-h ischemia hearts. These findings suggest that myocardial ischemia induces a factor or factors which stimulate GLUT1 expression in non-ischemic as well as ischemic myocardial regions. Increased GLUT1 expression may play a role in augmenting glucose uptake during ischemia.

Mitochondrial function, GSH and iron in neurodegeneration and Lewy body diseases. The cause of neuronal loss in patients with idiopathic Parkinson's disease is unknown. Oxidative stress and complex I deficiency have both been identified in the substantia nigra in Parkinson's disease but their place in the sequence of events resulting in dopaminergic cell death is uncertain. We have analysed respiratory chain activity, iron and reduced glutathione concentrations in Parkinson's disease substantia innominata and in the cingulate cortex of patients with Parkinson's disease, Alzheimer's disease and dementia with Lewy bodies to investigate their association with neuronal death and Lewy body formation. No abnormalities of mitochondrial function, iron or reduced glutathione levels were identified in Parkinson's disease substantia innominata or cingulate cortex.

The role of confounding factors such as ultraviolet radiation (UV), add another level of complexity to the study of arsenic carcinogenesis and the cancer-risk assessment on humans. We hypothesized that arsenicals are capable of overriding the growth arrest caused by UV treatment and may lead to selective proliferation. To test this hypothesis, a primary normal human epidermal keratinocyte (NHEK) cell culture model was used. One group was pre-exposed to UVB (100 mJ/cm(2)) that arrested a majority ( approximately 95%) of cells in G0/G1 (+UV) and a second group was not exposed to UV (-UV). Treatment of cells with various arsenicals [0-12 microM of inorganic arsenite (iAs), 0-2 microM of methyl oxoarsine (MMAs III) and 0-3 microM of iododimethyl arsine (DMAs III)] indicated a concentration-dependent increase in proliferation at 24 h in the order of DMAs III > MMAs III > iAs. Flow-cytometric analyses revealed differential effects on cell cycle distribution. Analysis of a battery of cell cycle proteins (cyclin D1, cdk5, PCNA, cdc25A and cdc25C) indicated exposure-specific differential expression profiles. Increased activation of JNK phosphorylation (5-10-fold) in the +UV group and the synergistic increase with methyl arsenicals suggested that JNK might be involved in cell survival and proliferative signaling. Induction of EGF levels and increased phosphorylation of the EGF receptor by arsenicals (+UV) suggested that the EGF signaling pathway might mediate arsenical-induced cell proliferation of NHEK cells. Differential activation of ERK1/2 by arsenicals (+/-UV) suggested that EGF-mediated cell proliferation by arsenicals in UV-treated NHEK cells may not involve ERK activation. Taken together, the data suggest that both UV exposure and methylation status of the arsenicals dictate the participation of key cell cycle proteins and related signaling events in arsenical-induced cell proliferation." ], "offsets": [ [ 125, 2134 ] ] } ]

The effect of arsenicals on ultraviolet-radiation-induced growth arrest and related signaling events in human keratinocytes. The molecular mechanisms mediating arsenic-induced carcinogenesis are not well understood. The role of confounding factors such as ultraviolet radiation (UV), add another level of complexity to the study of arsenic carcinogenesis and the cancer-risk assessment on humans. We hypothesized that arsenicals are capable of overriding the growth arrest caused by UV treatment and may lead to selective proliferation. To test this hypothesis, a primary normal human epidermal keratinocyte (NHEK) cell culture model was used. One group was pre-exposed to UVB (100 mJ/cm(2)) that arrested a majority ( approximately 95%) of cells in G0/G1 (+UV) and a second group was not exposed to UV (-UV). Treatment of cells with various arsenicals [0-12 microM of inorganic arsenite (iAs), 0-2 microM of methyl oxoarsine (MMAs III) and 0-3 microM of iododimethyl arsine (DMAs III)] indicated a concentration-dependent increase in proliferation at 24 h in the order of DMAs III > MMAs III > iAs. Flow-cytometric analyses revealed differential effects on cell cycle distribution. Analysis of a battery of cell cycle proteins (cyclin D1, cdk5, PCNA, cdc25A and cdc25C) indicated exposure-specific differential expression profiles. Increased activation of JNK phosphorylation (5-10-fold) in the +UV group and the synergistic increase with methyl arsenicals suggested that JNK might be involved in cell survival and proliferative signaling. Induction of EGF levels and increased phosphorylation of the EGF receptor by arsenicals (+UV) suggested that the EGF signaling pathway might mediate arsenical-induced cell proliferation of NHEK cells. Differential activation of ERK1/2 by arsenicals (+/-UV) suggested that EGF-mediated cell proliferation by arsenicals in UV-treated NHEK cells may not involve ERK activation. Taken together, the data suggest that both UV exposure and methylation status of the arsenicals dictate the participation of key cell cycle proteins and related signaling events in arsenical-induced cell proliferation.

Bacterial vaginosis and surgical site infections. Bacterial vaginosis is the most common cause of abnormal vaginal discharge or malodor, affecting up to one third of US women. Most women with bacterial vaginosis are unaware of the infection, making it difficult to diagnose in the absence of a microscopic examination of vaginal discharge or using point-of-care testing. Untreated bacterial vaginosis elevates the risk of postoperative surgical infections in women undergoing obstetric and gynecological procedures. Treatment with antimicrobial agents that target bacterial vaginosis has been shown to reduce the rate of postoperative infections following hysterectomy and surgical abortions. Furthermore, in a cost-comparison model, screening for and treatment of bacterial vaginosis prior to hysterectomy was shown to be superior to no screening in terms of infection rates and cost. The bacterial vaginosis diagnostic criteria are simple and screening tests are inexpensive; bacterial vaginosis screening is a relatively fast process in patients who present for preoperative appointments. Treatment options approved by the Food and Drug Administration include metronidazole, clindamycin, tinidazole, and secnidazole. Given the prevalence of bacterial vaginosis and the risks associated with operating on a woman with untreated bacterial vaginosis, women undergoing hysterectomy, surgical abortion, and potentially cesarean delivery should be screened for bacterial vaginosis, and those who screen positive should be treated with an appropriate antimicrobial agent.

Unusual left ventricular wall motion and a loud added sound during the isovolumic relaxation period in a patient with hypertensive heart disease. A 69 year old woman with hypertensive heart disease had a loud added sound which coincided with a sudden interruption of the early diastolic motion of the left ventricular posterior wall, as visualised by M mode echocardiography, and came just before early diastolic transmitral flow, as measured by a pulsed Doppler echocardiogram. Early diastolic motion velocity from the base to the middle of the posterior wall, assessed by pulsed Doppler tissue imaging, was markedly high and sharp, and its peak coincided with the sound. A notch, similar to that in the posterior wall motion, occurred in the left ventricular pressure curve during early diastole.

The inevitable outcome is wait lists for surgery. The objective of this study is to report cross-sectional health data collected from a broad sample of patients awaiting elective surgery and shed light on potential non-surgical treatments to improve health. RESEARCH DESIGN: Prospective cross-sectional survey of patients newly enrolled on the surgical wait list in the Vancouver Coastal Health region. Multivariate regression models were used to estimate the associations between patient characteristics and health, pain and depression. MEASURES: Health status instruments were used to measure study participants' general health, pain, and depression immediately after they were enrolled on the wait list for one of the targeted elective surgeries. RESULTS: A majority of patients reported some problems with pain or discomfort, and a large portion reported problems associated with anxiety or depression. Orthopedic patients were significantly more likely to report problems with mobility, usual activities and pain/discomfort. Neurosurgery patients were the most likely to report significant and severe depression. CONCLUSIONS: The high rates of pain and depression not only have implications for patients' immediate health, but may also affect long-term surgical outcomes.

Health of patients on the waiting list: Opportunity to improve health in Canada? INTRODUCTION: A number of countries have healthcare systems where access to elective surgery is constrained. The inevitable outcome is wait lists for surgery. The objective of this study is to report cross-sectional health data collected from a broad sample of patients awaiting elective surgery and shed light on potential non-surgical treatments to improve health. RESEARCH DESIGN: Prospective cross-sectional survey of patients newly enrolled on the surgical wait list in the Vancouver Coastal Health region. Multivariate regression models were used to estimate the associations between patient characteristics and health, pain and depression. MEASURES: Health status instruments were used to measure study participants' general health, pain, and depression immediately after they were enrolled on the wait list for one of the targeted elective surgeries. RESULTS: A majority of patients reported some problems with pain or discomfort, and a large portion reported problems associated with anxiety or depression. Orthopedic patients were significantly more likely to report problems with mobility, usual activities and pain/discomfort. Neurosurgery patients were the most likely to report significant and severe depression. CONCLUSIONS: The high rates of pain and depression not only have implications for patients' immediate health, but may also affect long-term surgical outcomes. This study draws attention to recognizing a wider array of morbidity, some potentially requiring non-surgical interventions, while patients wait for elective surgery. Policy options include re-examining the surgical triage system and expanding surgical capacity to match self-reported health.

The effect of telemetry on urban prehospital cardiac care. A three-year, controlled trial of the use of telemetry in the prehospital care of cardiac patients was conducted in a major metropolitan area. Five of the ten paramedic squads in the city used telemetry; the other five squads did not. We studied the effect of telemetry on the following: paramedics' abilities to recognize ECGs in a written test; paramedics' abilities to identify ECG arrhythmias in the field; length of time spent by paramedics in the field; survival rates of patients with ventricular fibrillation (VF) cared for by paramedics; abilities of base station physicians to interpret telemetered ECGs; and attitudes of paramedics toward using telemetry. Telemetry was not found to affect the abilities of paramedics to read ECGs in either test or field situations. Paramedics who used telemetry spent more time in the field with their patients than did paramedics who did not use telemetry (P less than .02). We found no statistically significant effect of telemetry on survival rates of VF patients. Using matched ECGs, readings by base station physicians were found to be more accurate than were those by paramedics (P less than .01). Paramedics overwhelmingly reported that telemetry did not help them to save patients' lives, but that it did help them to treat patients with certain arrhythmias. The results suggest that telemetry may not improve either paramedics' abilities to identify arrhythmias or prehospital care for all cardiac patients. The implications for emergency services researchers are discussed.

It is concluded that the inverse position of the acylamide linkage does not modify, while its replacement by an esteric group completely abolishes the desensitizing activity.

Desensitizing potency was not parallel with the stimulating effect of the compounds, e.g. the strongly pungent homovanilloyl-octylester failed to desensitize the receptors, while the less pungent homovanilloyl-dodecylamide proved to be a more potent desensitizing agent than capsaicin itself. It is concluded that the inverse position of the acylamide linkage does not modify, while its replacement by an esteric group completely abolishes the desensitizing activity. In contrast to the stimulating effect, in desensitizing action the presence of an alkyl chain is essential and its optimal length corresponds to 10-12 C atoms. On the basis of these results the possible molecular interactions at the site of action are discussed.

Using the International Retrospective Study of the Pipeline Embolization Device registry, we studied demographic, aneurysm, and procedural characteristics associated with intraparenchymal hemorrhage following Pipeline Embolization Device treatment. MATERIALS AND METHODS: We identified patients in the International Retrospective Study of the Pipeline Embolization Device registry with intraparenchymal hemorrhage unrelated to index aneurysm rupture post-Pipeline Embolization Device treatment. The rate of intraparenchymal hemorrhage was determined by baseline demographics, comorbidities, aneurysm characteristics, and procedural characteristics (including anticoagulation use, platelet testing, number of devices used, sheaths, catheters, and guidewires). Categoric variables were compared with chi(2) testing, and continuous variables were compared with the Student t test. RESULTS: Of 793 patients with 906 aneurysms, 20 (2.5%) had intraparenchymal hemorrhage. Fifteen intraparenchymal hemorrhages (75.0%) occurred within 30 days of treatment (median, 5 days; range, 0-150 days). Nine patients with intraparenchymal hemorrhage (45.0%) died, 10 (50.0%) had major neurologic morbidity, and 1 had minor neurologic morbidity (5.0%). Intraparenchymal hemorrhage was ipsilateral to the Pipeline Embolization Device in 16 patients (80%) and contralateral in 3 patients (15.0%). Variables associated with higher odds of intraparenchymal hemorrhage included treatment of ruptured aneurysms (OR, 4.44; 95% CI, 1.65-11.94; P = .005) and the use of >= 3 Pipeline Embolization Devices (OR, 4.10; 95% CI, 1.34-12.58; P = .04).

CONCLUSIONS: Spontaneous intraparenchymal hemorrhage following Pipeline Embolization Device treatment is a rare-but-devastating complication, with nearly all patients having morbidity or mortality.
