BACKGROUND Portal vein thrombosis (PVT) has been mentioned as a potential obstacle to liver transplantation (LTx). OBJECTIVE To review the impact of PVT on orthotopic liver transplant (OLT) outcome. METHOD Between January 2006 and April 2009, 440 OLT were performed in Shiraz Transplant Unit of whom, 35 (7.9%) cases had old PVT with recanalization. Data were retrospectively collected regardi...

Driver fatigue remains a significant cause of motor-vehicle accidents worldwide. New technologies are increasingly utilised to improve road safety, but there are no effective on-road measures for fatigue. While simulated driving tasks are sensitive, and simple performance tasks have been used in industrial fatigue management systems (FMS) to quantify risk, little is known about the relationship...

INTRODUCTION Portal vein thrombosis (PVT) is a relatively uncommon complication after abdominal surgery. CASE REPORT We report an even more unusual case of PVT 10 days after an uncomplicated laparoscopic cholecystectomy, believed to be only the fourth reported case in the literature of this rare complication. CONCLUSION Albeit extremely rare, PVT should be included in the differential diagn...

BACKGROUND/AIMS Prognostic scores currently used in cirrhotic patients do not include thrombotic risk factors (TRFs). Predicting factors of portal vein thrombosis (PVT) development are still unknown. We wanted to describe TRFs as a function of liver disease severity using the MELD score and assess the role of local and systemic TRFs as predictors of PVT development in cirrhotic patients. METH...

Atrial fibrillation is a serious clinical problem, which is associated with systemic thrombosis such as cerebral infarction. Pulmonary vein myocardiumpromotes andmaintains atrial fibrillation. Catheter ablation is done to cure atrial fibrillation to cut down the current flow from pulmonary vein myocardium. Although pulmonary vein thrombi (PVT) are thought to be a rare complication of certain tu...

The study investigated the thermal performance of a photovoltaic (PVT) collector with twisted absorber tube and nanoparticle-enhanced phase change material (nano-PCM). PVT consisted tubes, container filled nano-PCM, (PV) panel. To assess its efficiency, five different configurations were tested using an indoor solar simulator. analyzed as follows: (a) unenhanced PV panel, (b) circular tubes (C-...

Cirrhosis has always been regarded as hemorrhagic coagulopathy caused by the reduction in the hepatic synthesis of procoagulant proteins. However, with the progression of liver disease, the cirrhotic patient undergoes a high rate of thrombotic phenomena in the portal venous system. Although the progression of liver failure produces a reduction in the synthesis of anticoagulant molecules, a test...

BACKGROUND Recent studies examining mechanisms of defibrillation have focused on prolongation of graded cellular response duration during refractory period stimulation. This mechanism assumes that defibrillation shocks interact with ventricular cells during the process of repolarization. METHODS AND RESULTS To test this assumption, we examined monophasic action potentials (MAPs) from 171 epis...

BACKGROUND Treatment of portal vein thrombosis (PVT) in patients with liver cirrhosis is not well established. AIM We intended to assess the safety and efficacy of low molecular weight heparin (LMWH) to treat PVT in cirrhotic patients. STUDY All 39 patients diagnosed with non-neoplastic PVT and cirrhosis from June 2005 to December 2006 were evaluated for anticoagulation therapy (AT). PVT wa...

Previous evidence has shown that vagal nerve activity modulates ventricular arrhythmias in patients and in animal models. However, the effects of direct vagus nerve stimulation on ventricular tachyarrhythmias brought by direct sympathetic nerve stimulation have not been elucidated. In the present study, the effects of electrical stimulation of the left cervical vagus nerve on ventricular tachyc...
