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 ...

This paper presents numerical and experimental analyses aimed at evaluating the technical and economic feasibility of photovoltaic/thermal (PVT) collectors. An experimental setup was purposely designed and constructed in order to compare the electrical performance of a PVT solar field with the one achieved by an identical solar field consisting of conventional photovoltaic (PV) panels. The expe...

Pulmonary vein thrombosis (PVT) is a challenging diagnosis and has been described in association with or as a complication of pulmonary tumors, lung surgeries, atrial myxoma, and after radiofrequency catheter ablation for atrial fibrillation. There are not many reported cases of PVT associated with medication use. We present a case of a 53-year-old male with a history of severe persistent asthm...

In deeply scaled CMOS technologies, two major non-ideal factors are threatening the survival of the CMOS; i) PVT (process, voltage, and temperature) variations and ii) leakage power consumption. In this paper, we propose a novel postsilicon tuning methodology to scale optimum voltage and frequency “dynamically”. The proposed design technique will use our PVT sensor circuits to monitor the varia...

A common complication of prosthetic heart valves is thrombosis. Although the incidence of prosthetic valve thrombosis (PVT) in the tricuspid position is high, there are not enough data on the management of it, in contrast to left-sided PVT. Here, we describe three cases of tricuspid PVT with three different management approaches: thrombolytic therapy; close observation with oral anticoagulants;...
