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-...

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...

Portal vein thrombosis (PVT) not associated with hepatocellular carcinoma is considered a frequent complication of liver cirrhosis but, unlike PVT occurring in non-cirrhotic patients, very few data are available on its natural history and management. The reduced portal blood flow velocity is the main determinant of PVT but, as in other venous thromboses, multiple factors local and systemic, inh...

This study evaluated the electrical performance of a photovoltaic-thermal (PVT) system using water as cooling fluid (PVT/w), with adaptation, in photovoltaic module device for heating without direct contact cell and air secondary working fluid. The PVT/w forced natural circulation was compared regime thermal accumulation hot supply by boiler reservoir relative to same PV panel original factory ...

Recent work has established that the paraventricular thalamus (PVT) is a central node in the brain reward-seeking pathway. This role is mediated in part through projections from hypothalamic peptide transmitter systems such as cocaine- and amphetamine-regulated transcript (CART). Consistent with this proposition, we previously found that inactivation of the PVT or infusions of CART into the PVT...

AIMS Left-sided prosthetic valve thrombosis (PVT) occurs frequently in developing countries and causes major morbidity and mortality. Fibrinolytic therapy (FT) is most commonly used as treatment, but increases the risk of stroke and bleeding. Urgent surgery may be more efficacious and cause fewer complications. Our aim was to compare the efficacy and safety of urgent surgery and FT for the trea...

Pressure-Volume-Temperature (PVT) properties are very important in the reservoir engineering computations. There are many approaches for predicting various PVT properties based on empirical correlations and statistical regression models. Last decade, researchers utilized neural networks to develop more accurate PVT correlations. These achievements of neural networks open the door to data mining...

Portal venous thrombosis (PVT) is a condition associated with high morbidity. The etiologies of PVT include intra-abdominal inflammation or infection, surgical intervention, abdominal malignancies such as hepatocellular carcinoma (HCC) and pancreatic carcinoma, or abnormality in coagulation caused by various reasons such as liver cirrhosis. Management of PVT should be based on its etiology and ...
