In order to determine the role of the coupling interval of a premature ventricular contraction (PVC) in the development of paroxysmal ventricular tachycardia (PVT) during the early phase of acute myocardial infarction in man, 52 male patients with documented acute myocardial infarction had 24-hour Holter monitoring commenced within 24 hours of the onset of prolonged chest pain. Review of the ta...

Portal vein (PV) thrombosis (PVT) is a rare condition with development of thrombosis in the PV and its branches. Further extension to the splenic and superior mesenteric vein (SMV) causes intestinal infarction, with a reported mortality of up to 50%. A variety of treatments for PVT exist including anticoagulation, thrombolysis, surgical thrombectomy, insertion of shunts, bypass surgery, and liv...

Equations of state are useful for description of fluid properties such as pressure-volumetemperature (PVT). However, the success estimation of such correlations depends mainly on the range of data which have originated. Therefore new models are highly required. In this work a new method is proposed based on Artificial Neural Network (ANN) for estimation of PVT properties of compounds. The data ...

The hallmark manifestations of Cushing's syndrome (CS) are well known, but hypercoagulability is perhaps least recognized. Patients with CS are at increased risk of both spontaneous and postoperative thromboembolism, with the significant majority of events occurring in the lower extremity and pulmonary venous circulations. We present a case of portal vein thrombosis (PVT) occurring in the setti...

A prior report found unusually high rates of performance validity test (PVT) failure in undergraduate research participants (31%-56%). The present study examined 110 undergraduate volunteers in three conditions (positive, neutral, or negative demand characteristics) in either an easy to hard or a hard to easy progression of neuropsychological tests using the Word Memory Test PVT. Neither demand...

Performance validity tests (PVTs) have been shown to relate to neuropsychological performance, but no studies have looked at the ecological validity of these measures. Data from 131 veterans with a history of mild traumatic brain injury from a multicenter Veterans Administration consortium were examined to determine the relation between scores on a self-report version of the Mayo-Portland Adapt...

Ischemic stroke is a serious clinical problem that crucially needs to be prevented. The three major pathophysiological mechanisms leading to ischemic strokes are cardiac embolisms, atherosclerotic large-vessel disease, and intracranial small-vessel disease. Left atrial appendage (LAA) thrombi in patients with an atrial fibrillation (AF) are the well-studied cardiac thrombi known to cause ischem...

Industrial process heating applications in the temperature range of 50°–250 °C consumes about 35% global fossil fuels, wherein solar thermal is envisaged as an alternative option. Outlet temperatures both flat-plate collector (FPC) and photovoltaic (PVT) are not high enough to serve industrial processes. In this article, a assisted (SAPH) system, FPC integrated series with PVT, has been designe...

BACKGROUND Cocaine- and amphetamine-regulated transcript (CART) has been demonstrated to play a role in regulating the rewarding and reinforcing effects of various drugs of abuse. A recent study demonstrated that i.c.v. administration of CART negatively modulates reinstatement of alcohol seeking, however, the site(s) of action remains unclear. We investigated the paraventricular thalamus (PVT) ...

Introduction Elbow injury, especially Ulnar Collateral Ligament (UCL) tear, is very common in baseball pitching. This is often attributed to high valgus torques repetitively stressing the ligament. The goal of this study was to research the effect of Elbow Flexion (EF) and arm External Rotation (ER) angle on Peak Valgus Torque (PVT) as well as ball velocity, using a three-folded approach. Metho...
