INTRODUCTION: Von Willebrand factor propeptide (VWF:Ag II) is proposed to be a more sensitive marker of acute endothelial activation than von Willebrand factor antigen (VWF:Ag). Simultaneous data on VWF:Ag and VWF:Ag II profiles are very limited following TIA and ischaemic stroke. METHODS: In this prospective, observational, case-control study, plasma VWF:Ag and VWF:Ag II levels were quantified in 164 patients≤4weeks of TIA or ischaemic stroke (baseline), and then ≥14days (14d) and ≥90days (90d) later, and compared with those from 27 healthy controls...

OBJECTIVES: Whereas left-sided congenital diaphragmatic hernias (L-CDH) have been extensively studied and their prognostic parameters delineated, right-sided hernias (R-CDH) have not. Published results remain inconclusive. The aim of this study is to evaluate if proven prognostic indicators of postnatal survival in the fetus with L-CDH apply to the fetus with R-CDH. METHODS: Retrospective single-center study of R-CDH fetuses with available prenatal studies assessed for fetal lung volume by means of ultrasound-measured observed versus expected (O/E) lung area to head circumference (LHR) and magnetic resonance-calculated O/E total lung volume (TLV) in a 12-year time period...

The catalytic solvolysis of Norway spruce (Picea abies L.) lignin in a formic acid/water media was explored at different temperatures and reaction times (283-397°C and 21-700min, respectively). Non-catalyzed experiments were compared with the effect of three different type of bifunctional catalysts (Pd/Al2O3, Rh/Al2O3 and Ru/Al2O3) and a solid Lewis acid (γ-Al2O3). We demonstrated that surface response methodology (RSM) and principal component analysis (PCA) were an adequate tool to: (i) evaluate the effect of the catalysts, temperature and reaction time in the oil yield, oil quality (H/C and O/C ratios, and Mw) and composition of the oil, (ii) establish the differences and/or similarities between the three bifunctional catalyst and (iii) to determine the role of the noble metal and the alumina support in the reaction system...

Survivin is a member of the inhibitor of apoptosis (IAP) family. The function of the survivin protein is to inhibit caspase activation, thereby leading to negative regulation of apoptosis or programmed cell death. This has been shown by the disruption of survivin induction pathways leading to an increased apoptosis and decreased tumour growth. These data suggest that survivin may provide a new target for cancer treatment, which would distinguish transformed cells from normal cells. In the present study, we aimed to investigate exon 1 of the survivin gene by means of methylation-specific PCR and evaluate its impact on survivin protein expression following DNA isolation and bisulphite modification in paraffin-embedded normal and tumour tissues of lung cancer patients with squamous cell carcinoma...

AIM: The electroneutral Na(+) ,HCO3(-) -cotransporter NBCn1 and Na(+) /H(+) -exchanger NHE1 regulate acid-base balance in vascular smooth muscle cells (VSMCs) and modify artery function and structure. Pathological conditions-notably ischemia-can dramatically perturb intracellular (i) and extracellular (o) pH and [Na(+) ]. We examined effects of low [Na(+) ]o and pHo on NBCn1 and NHE1 activity in VSMCs of small arteries. METHODS: We measured pHi by 2',7'-bis-(2-carboxyethyl)-5-(and-6)-carboxyfluorescein-based fluorescence microscopy of mouse mesenteric arteries and induced intracellular acidification by NH4(+) -prepulse technique...

The role of molecular oxygen dissolved in the solvent is often discussed as being an influential factor on particle oxidation during pulsed laser ablation in liquids. However, the formation of the particles during laser synthesis takes place under extreme conditions that enable the decomposition of the liquid medium. Reactive species of the solvent may then affect particle formation due to a chemical reaction in the reactive plasma. Experimental results show a difference between the role of dissolved molecular oxygen and the contribution from the oxygen in water molecules...

The recurrence rate of coronary stent thrombosis (ST) is high. Patients with ST often demonstrate high on-treatment platelet reactivity (HPR). It is suggested that patients at high risk of atherothrombotic events, that is patients with ST, could benefit from tailored antiplatelet therapy (APT). This study evaluated whether tailored APT, based on platelet function testing, reduced the rate of cardiac death and/or recurrent ST at 1 year after ST, compared with a historical cohort of patients with ST without tailored APT...

We propose a methodology to predict the cardiac epicardial and mediastinal fat volumes in computed tomography images using regression algorithms. The obtained results indicate that it is feasible to predict these fats with a high degree of correlation, thus alleviating the requirement for manual or automatic segmentation of both fat volumes. Instead, segmenting just one of them suffices, while the volume of the other may be predicted fairly precisely. The correlation coefficient obtained by the Rotation Forest algorithm using MLP Regressor for predicting the mediastinal fat based on the epicardial fat was 0...
