JNK3 is required for the cytoprotective effect of exendin 4.

Preservation of beta cell against apoptosis is one of the therapeutic benefits of the glucagon-like peptide-1 (GLP1) antidiabetic mimetics for preserving the functional beta cell mass exposed to diabetogenic condition including proinflammatory cytokines. The mitogen activated protein kinase 10 also called c-jun amino-terminal kinase 3 (JNK3) plays a protective role in insulin-secreting cells against death caused by cytokines. In this study, we investigated whether the JNK3 expression is associated with the protective effect elicited by the GLP1 mimetic exendin 4.

Signet ring cell adenocarcinomas: different clinical-pathological characteristics of oesophageal and gastric locations.

Aims: The incidence of oesogastric (OG) signet ring cell adenocarcinoma (SRC) is increasing in Western countries. The differential characteristics between oesophageal and gastric SRC tumours are unknown. We aimed to investigate the role of tumour location on prognosis in OG SRC.

Thermodynamics of mixing water with dimethyl sulfoxide, as seen from computer simulations.

The Helmholtz free energy, energy, and entropy of mixing of eight different models of dimethyl sulfoxide (DMSO) with four widely used water models are calculated at 298 K over the entire composition range by means of thermodynamic integration along a suitably chosen thermodynamic path, and compared with experimental data. All 32 model combinations considered are able to reproduce the experimental values rather well, within RT (free energy and energy) and R (entropy) at any composition, and quite often the deviation from the experimental data is even smaller, being in the order of the uncertainty of the calculated free energy or energy, and entropy values of 0.1 kJ/mol and 0.

Psychrobacter sanguinis: an unusual bacterium for nosocomial meningitis.

We report the first case of postneurosurgical meningitis due to Psychrobacter sanguinis, identified only by 16S rRNA analysis. Psychrobacter spp. usually live in deep sea environments and cold habitats.

Botulinum toxin treatment of pes cavovarus in a child suffering from autosomal recessive axonal Charcot-Marie-Tooth neuropathy (AR-CMT2).

In a 12-year old girl suffering from autosomal recessive axonal Charcot-Marie-Tooth (CMT) neuropathy, pes cavovarus was treated with botulinum toxin injection in the tibialis posterior. The patient underwent a clinical evaluation, video analysis of spatiotemporal gait parameters and dynamic foot plantar pressure assessment before treatment and then two weeks, three months and six months thereafter. The video gait analysis revealed a decrease in varus during the swing phase of gait.

Quality control for retinal OCT in multiple sclerosis: validation of the OSCAR-IB criteria.

Background: Retinal optical coherence tomography (OCT) permits quantification of retinal layer atrophy relevant to assessment of neurodegeneration in multiple sclerosis (MS). Measurement artefacts may limit the use of OCT to MS research.

Objective: An expert task force convened with the aim to provide guidance on the use of validated quality control (QC) criteria for the use of OCT in MS research and clinical trials.

Mercury intrusion porosimetry and assessment of cement-dentin interface of anti-washout-type mineral trioxide aggregate.

Introduction: One of the disadvantages of mineral trioxide aggregate (MTA) is washout (ie, the tendency of freshly prepared cement paste to disintegrate upon early contact with physiological fluids). A novel MTA (MTA Plus; Prevest Denpro, Jammu City, India) exhibits low washout and superior physical properties when mixed with a gel instead of water. When used as a root-end filler, MTA is in contact with both bone and root dentin.

Development of multilayer microcapsules by a phase coacervation method based on ionic interactions for textile applications.

The present study describes the development of multilayer microcapsules by 11 alternate additions of chitosan (Chi) and sodium dodecyl sulfate (SDS) in a combined emulsification and phase coacervation method based on ionic interactions. After an alkali treatment, microcapsules are applied on polyester (PET) fabric by a padding process to investigate their wash-durability on fabric. Air atmospheric plasma treatment is performed on PET fabric to modify the surface properties of the textiles.

TRα protects against atherosclerosis in male mice: identification of a novel anti-inflammatory property for TRα in mice.

Hypothyroidism is associated with an increased occurrence of atherosclerosis, suggesting some protective role for thyroid hormones (THs). Hypercholesterolemia is one of the major risk factor to develop this disease. Here, we show that the well-known TH cholesterol lowering effect was dependent on TH nuclear receptor (TR)β liver activity.

Baclofen-induced manic symptoms: case report and systematic review.

Background: The gamma-aminobutyric acid type B receptor agonist baclofen is approved for spasticity and is used off-label for diverse types of addictive disorders, notably alcohol dependence. Baclofen may induce numerous neuropsychiatric adverse drug reactions, including behavioral disinhibition. However, this precise adverse drug reaction has never been assessed using either a validated causality algorithm or a scale for manic symptoms.

Atherogenic dyslipidemia and residual cardiovascular risk in statin-treated patients.

Background And Purpose: Treatment with statins reduces the rate of cardiovascular events in high-risk patients, but residual risk persists. At least part of that risk may be attributable to atherogenic dyslipidemia characterized by low high-density lipoprotein cholesterol (≤40 mg/dL) and high triglycerides (triglycerides≥150 mg/dL).

Methods: We studied subjects with stroke or transient ischemic attack in the Prevention of Cerebrovascular and Cardiovascular Events of Ischemic Origin With Terutroban in Patients With a History of Ischemic Stroke or Transient Ischemic Attack (PERFORM; n=19,100) and Stroke Prevention by Aggressive Reduction in Cholesterol Levels (SPARCL; n=4731) trials who were treated with a statin and who had high-density lipoprotein cholesterol and triglycerides measurements 3 months after randomization (n=10,498 and 2900, respectively).

Exercise performance is regulated during repeated sprints to limit the development of peripheral fatigue beyond a critical threshold.

We hypothesized that exercise performance is adjusted during repeated sprints in order not to surpass a critical threshold of peripheral fatigue. Twelve men randomly performed three experimental sessions on different days, i.e.

Long-term outcome of children receiving percutaneous endoscopic gastrostomy feeding.

Objectives: The aim of the present study was to analyze the long-term follow-up of children receiving percutaneous endoscopic gastrostomy (PEG) in terms of survival, nutritional outcome, and weaning from enteral nutrition. The secondary objectives were to evaluate the complications related to PEG and the outcome of patients with neurological disability.

Methods: The present study was a single-center retrospective study including all of the 368 patients who underwent PEG from 1990 to 2003 in our tertiary hospital.

A central role for GRB10 in regulation of islet function in man.

Variants in the growth factor receptor-bound protein 10 (GRB10) gene were in a GWAS meta-analysis associated with reduced glucose-stimulated insulin secretion and increased risk of type 2 diabetes (T2D) if inherited from the father, but inexplicably reduced fasting glucose when inherited from the mother. GRB10 is a negative regulator of insulin signaling and imprinted in a parent-of-origin fashion in different tissues. GRB10 knock-down in human pancreatic islets showed reduced insulin and glucagon secretion, which together with changes in insulin sensitivity may explain the paradoxical reduction of glucose despite a decrease in insulin secretion.

Use of dried blood spots and inductively coupled plasma mass spectrometry for multi-element determination in blood.

The paper describes the development of an inductively coupled plasma mass spectrometry (ICP MS) method for multitrace element determination in dried blood spots (DBSs). The analytical conditions were optimized using Seronorm™ L-3 and L-1 Certified Reference Materials. The best results were obtained by sampling blood drops on a decontaminated PVDF filter membrane.

Accuracy of alpha amylase in diagnosing microaspiration in intubated critically-ill patients.

Objectives: Amylase concentration in respiratory secretions was reported to be a potentially useful marker for aspiration and pneumonia. The aim of this study was to determine accuracy of α-amylase in diagnosing microaspiration in critically ill patients.

Methods: Retrospective analysis of prospectively collected data collected in a medical ICU.

Unconventional surface plasmon resonance signals reveal quantitative inhibition of transcriptional repressor EthR by synthetic ligands.

EthR is a mycobacterial repressor that limits the bioactivation of ethionamide, a commonly used anti-tuberculosis second-line drug. Several efforts have been deployed to identify EthR inhibitors abolishing the DNA-binding activity of the repressor. This led to the demonstration that stimulating the bioactivation of Eth through EthR inhibition could be an alternative way to fight Mycobacterium tuberculosis.

Methods: All patients who underwent radical nephrectomy with inferior vena cava replacement by polytetrafluoroethylene expanded prosthesis for renal cancer associated with inferior vena cava thrombosis and a suspicion of inferior vena cava wall invasion from January 2000 to June 2011 were considered for this study. Demographic data, postoperative course, graft patency and survival data were evaluated.

PhosphoTyrosyl phosphatase activator of Plasmodium falciparum: identification of its residues involved in binding to and activation of PP2A.

In Plasmodium falciparum (Pf), the causative agent of the deadliest form of malaria, a tight regulation of phosphatase activity is crucial for the development of the parasite. In this study, we have identified and characterized PfPTPA homologous to PhosphoTyrosyl Phosphatase Activator, an activator of protein phosphatase 2A which is a major phosphatase involved in many biological processes in eukaryotic cells. The PfPTPA sequence analysis revealed that five out of six amino acids involved in interaction with PP2A in human are conserved in P.

Body representations and brain damage.

We review changes in body representation in patients with brain hemisphere damage and discuss their relationship with impaired limb movements in peripersonal space, navigation between objects/obstacles and control of the body's general posture and balance. The egocentric representation of the body's median sagittal axis (considered as the main zone around which movements are anchored) has been studied in most detail. This reference is distorted in patients with spatial neglect and involves a combination of ipsilesional translation and contralesional tilt.

Effect of oral cladribine on time to conversion to clinically definite multiple sclerosis in patients with a first demyelinating event (ORACLE MS): a phase 3 randomised trial.

Background: Patients who develop relapsing-remitting multiple sclerosis (MS) present with a first clinical demyelinating event. In this double-blind, multicentre, randomised, phase 3 study we investigated the effect of oral cladribine on conversion to clinically definite MS in patients with a first clinical demyelinating event, when given at the same doses shown to be effective in relapsing-remitting MS.

Methods: Between Oct 21, 2008, and Oct 11, 2010, we recruited patients aged 18-55 years, inclusive, from 160 hospitals, private clinics, or treatment centres in 34 countries.

Costs and benefits of tool-use on the perception of reachable space.

Previous studies have shown that using a tool modifies in a short time-scale both near-body space perception and arm-length representation in the body schema. However, to date no research has specifically investigated the effect of tool-use on an action-related perceptual task. We report here a study assessing the effect of tool-use on the perception of reachable space for perceptual estimates made in reference to either the tool or the hand.
