INTRODUCTION Hepatic portal venous gas is the presence of gas within the portal venous system that can result from a variety of insults to the gastrointestinal system, and which may be a diagnostic clue to ominous abdominal pathologies, such as acute bowel ischemia or necrosis. CASE We report a case of a 71-year-old man with acute onset abdominal pain whose initial radiologic testing showed e...

Software evolution is an essential concept underlying the engineering of corporate portals. Due to the complexity of such systems, it requires great effort and is not advisable to design and implement a feature-complete corporate solution. The concept of evolutionary portal development helps portal engineers to cope with design complexity. While the technical perspective on component based soft...

A 64-year-male underwent a liver biopsy based on clinical concern for primary biliary cirrhosis. The biopsy, which yielded normal results, was uneventful, with no immediate postbiopsy complications. A later MRI demonstrated early opacification of the right portal vein on arterial-phase imaging, suggesting communication between the right hepatic artery and the right portal vein. A conservative, ...

Many Grid portal architectures have three layers: browser, portal and Grid environment. We design a multi-layer Grid portal architecture, which introduced Mobile Agent; the mobile agents can gain the different information of the Grid resources. This paper analyzes the multi-layer architecture of Grid portal, presents the security strategy and introduces the function of different mobile agent.

This study investigates the status of portal implementation in the academic world. A two-stage cluster analysis was used to divide the sample colleges and universities into three groups (Internal Focus Implementers, External Focus Implementers and Starters) based on the portal features implemented by each school. The differences among the three groups were assessed based on the type of school a...

INTRODUCTION We report for the first time a unique case of VACTERL (vertebral anomalies, anal atresia or imperforate anus, cardiac anomalies, tracheoesophageal fistula, renal and limb defect) spectrum associated with portal hypertension. The occurrence of both VACTERL spectrum and extrahepatic portal hypertension in a patient has not been reported in the literature. We examined whether or not t...

BACKGROUND Portal hypertension is a clinical syndrome associated with the development of a hyperdynamic circulation and gastroesophageal varices. Aim. To evaluate the antioxidant effect of N-acetylcysteine on portal hypertensive rats. MATERIAL AND METHODS Portal hypertension was induced by partial portal vein ligation (PPVL). Oxidative damage in the stomach was measured by lipoperoxidation tr...

BACKGROUND Mean portal vein diameter is considered as the best indicator for portal hypertension. However, the cutoff point differs from study to study (above 10-15 mm) despite the existence of normal mean portal vein diameter between 10-15 mm in different settings.This implies the existence of limited evidence on normal portal vein diameter for all populations in all countries prior to setting...

The aim of the present study was to improve upon the traditional model of pre-hepatic portal hypertension in rats, and simulate the anhepatic phase of orthotopic liver transplantation without veno-venous bypass. A reversible model of portal hypertension was induced by portal vein ligation, with a label ring ligated along the portal vein. A total of 135 male Wistar rats were divided into three g...

RATIONALE Portal vein thrombosis is a complication after liver transplantation and cavernous transformation of the portal vein (CTPV) is a result of portal vein thrombosis, with symptoms of portal hypertension revealed by an enhanced CT scan. Meso-Rex bypass is an artificial shunt connecting the left portal vein to the superior mesenteric vein and is mainly used for idiopathic cavernomas. This ...
