The paraventricular nucleus of the thalamus (PVT) projects to the central nucleus of the amygdala and recent experimental evidence indicates a role for the PVT in conditioned fear. Furthermore, the PVT contains a high density of orexin receptors and fibers and acute injections of orexin antagonist into the PVT produce anxiolytic effects. The present study was done to determine if administration...

The present invention relates generally to the integrated circuits(ICs) & in particular to process, voltage & temperature(PVT) variations in an ICs. PVT variations are critical factor that hamper performance of Ics forexample PVT variations can result in a change in setup &hold times of synchronous circuits. Different components of asynchronous circuit are driven by a common system clock. There...

Forty-five consecutive patients with polymorphous ventricular tachycardia (PVT) were studied. The arrhythmia proved to be of a drug-related cause in 27 and due to an electrolyte disorder in four patients. Coexistent cardiac diseases without metabolic or drug-related abnormalities included ischemic heart disease in three, cardiomyopathy in three, and mitral valve prolapse in two. PVT was exercis...

Extinction promotes abstinence from drug seeking. Extinction expression is an active process, dependent on infralimbic prefrontal cortex (ilPFC). However, the neurocircuitry mediating extinction expression is unknown. Here we studied the neural mechanisms for expression of extinction of alcoholic beer seeking in rats. We first examined the pattern of activation in prefrontal cortex projections ...

The presence of occlusive portal vein thrombosis (PVT) greatly changes the natural history of liver cirrhosis, because it not only significantly increases the incidence of variceal rebleeding but also negatively influences the survival. However, due to the absence of strong evidence, no standard treatment algorithm for the secondary prophylaxis of variceal bleeding in cirrhotic patients with no...

BACKGROUND Treatment of non-malignant portal vein thrombosis (PVT) in patients with cirrhosis has been neglected in the past because of the fear of bleeding complications when using anticoagulation and due to the technical difficulties associated with the implantation of the transjugular intrahepatic portosystemic shunt (TIPS). However, PVT has a negative impact on outcome and compromises liver...

Portal vein thrombosis (PVT) is considered a common complication of liver cirrhosis. Its prevalence increases with liver disease severity, reaching 25% in patients awaiting liver transplantation (LT). The majority of patients with cirrhosis are diagnosed incidentally with PVT during routine ultrasound in their cirrhosis follow-up. Doppler ultrasound is the recommended first-line investigation. ...

background portal vein thrombosis (pvt) is one of the most common causes of extrahepatic portal hypertension in children, which may follow neonatal umbilical vein catheterization. the incidence rates of catheter-related pvt, in infants and children vary in different studies. this study aimed to determine pvt incidence in the children under 3 years old with a history of neonatal umbilical vein c...

Cirrhosis can occur with the development of portal vein thrombosis (PVT). PVT may aggravate portal hypertension, and it can lead to hepatic decompensation. The international guideline recommends for anticoagulation treatment to be maintained for at least 3 months in all patients with acute PVT. Low-molecular-weight-heparin and changing to warfarin is the usual anticoagulation treatment. However...

1. Hospital Santa Catarina de Blumenau, Blumenau, SC, Brazil. Mailing Address: Dr. Maurício Fabro. Rua Tobias Barreto, 266, ap. 304, Vila Nova. Blumenau, SC, Brazil, 89035-070. E-mail: [email protected]. There is no defined treatment for PVT, and possible treatment strategies include use of anticoagulant drugs, NSAIDs, elastic socks and rest. However, the different therapies have shown ...
