BACKGROUND As survival and outcomes continue to improve in neonates born prematurely, there is an increasing need to promptly identify and treat pulmonary hypertension (PHT) in this population. Several echocardiographic indices have been used to evaluate for PHT. There is no clear consensus on how to utilize these parameters specifically for the evaluation of PHT in infants with chronic lung di...

Pseudomonas syringae is a phytopathogenic bacterium widely spread on terrestrial plants. Sulfodiaminophosphinyl tripeptide Phaseolotoxins (PHTs), produced by P. syringae pv. phaseolicola and P. syringae pv. actinidiae, represent a kind of antimetabolic phytotoxins. PHTs inhibit host cell Ornithine transcarbamylase (OTCase) activity and induce Arginine auxotrophic phenotype. The biosynthesis of ...

BACKGROUND Pulmonary hypertension (PHT) is a significant cause of mortality in patients with sickle cell disease (SCD). Few studies on PHT in SCD have been carried out in children. This study aimed to estimate the prevalence of PHT in children with sickle cell anaemia (SCA) and determine its clinical and laboratory correlates. METHODS In this cross sectional study, evaluation involved obtaini...

INTRODUCTION Pulmonary hypertension (PHT) has been reported to occur in a considerable proportion of patients with end-stage renal disease (ESRD). It is a progressive condition of the pulmonary circulation that poses prognostic importance. In this study, we sought to investigate the prevalence and the predictors of PHT among ESRD patients undergoing renal transplantation. PATIENTS AND METHODS...

In this study, we investigated the relative efficacy of different classes of commonly used anti-epileptic drugs (AEDs) with different mechanisms of action, individually and in combination, to suppress epileptiform discharges in an in vitro model. Extracellular field potential were recorded in 450 μm thick transverse hippocampal slices prepared from juvenile Wistar rats, in which "epileptiform d...

BACKGROUND Upper gastrointestinal bleeding (UGIB) has been classified into portal and non-portal hypertension (PHT) bleeding causes. Differentiating the two major categories of UGIB is therefore important for selection of the appropriate empirical treatment. OBJECTIVE To evaluate the potential of certain clinical parameters for predicting the cause of UGIB. MATERIAL AND METHOD The records o...

BACKGROUND Limited data are available on the impact of prehospital thrombolysis (PHT) in the "real-world" setting. METHODS AND RESULTS Of 443 intensive care units in France, 369 (83%) prospectively collected all cases of infarction (< or =48 hours of symptom onset) in November 2000; 1922 patients (median age, 67 years; 73% men) with ST-segment-elevation infarction were included, of whom 180 (...

BACKGROUND The severity of aortic regurgitation can be estimated using pressure half time (PHT) of the aortic regurgitation flow velocity, but the correlation between regurgitant fraction and PHT is weak. AIM To test the hypothesis that the association between PHT and regurgitant fraction is substantially influenced by left ventricular relaxation. METHODS In 63 patients with aortic regurgit...

Given uncertainty in the processes involved polar amplification, elucidating role of poleward heat and moisture transport is crucial. The Polar Amplification Model Intercomparison Project (PAMIP) permits robust separation effects sea ice loss from surface warming under climate change. We utilize a moist isentropic circulation framework that accounts for transport, condensation, eddy order to an...

BACKGROUND Emerging evidence shows that anti-inflammatory strategies targeting inflammatory monocyte subset could reduce excessive inflammation and improve cardiovascular outcomes. Functional expression of voltage-gated sodium channels (VGSCs) have been demonstrated in monocytes and macrophages. We hypothesized that mononuclear phagocyte VGSCs are a target for monocyte/macrophage phenotypic swi...
