The study investigated the factors that might significantly affect web portal usability. Results of the study were intended to serve as inputs for faculty web portal development of the University of the East-Manila. Descriptive statistics utilized questionnaire data from 82 faculty members. The data showed that most of the respondents were relatively young, were Master’s degree holders, were sk...

To evaluate the effect of portal hypertension and diminished portal venous blood flow to the liver on hepatic regeneration, male rats were subjected to partial portal vein ligation and subsequently to a two-thirds partial hepatectomy. The levels of ornithine decarboxylase activity at 6 h after partial hepatectomy were greater (p less than 0.001) in the rats with prior partial portal vein ligati...

Information Portals have gathered lot of attention among many organizations interested in a single point of access to their information and services. But developing portals from scratch is sometimes too expensive, so many vendors have proposed frameworks to make it affordable. Notwithstanding the frameworks the market offers seem stuck in a simplicity vs. flexibility trade off imposed by the We...

This article presents a model for Internet portal management. The model allows portal implementers to monitor and reflect on their portal implementation process and to identify appropriate strategies to improve their community building efforts. The portal management model (PMM) is a lifecycle model that contains four stages. Each stage is identified and described by a number of characteristics ...

The current study sought to ascertain whether portal vein glucose sensing is mediated by a metabolic fuel sensor analogous to other metabolic sensors presumed to mediate hypoglycemic detection (e.g., hypothalamic metabosensors). We examined the impact of selectively elevating portal vein concentrations of lactate, pyruvate, or beta-hydroxybutyrate (BHB) on the sympathoadrenal response to insuli...

BACKGROUND/AIMS In liver anatomy and surgery, is portal and hepatic vein segmentation (French segmentation) to be preferred over arteriobiliary segmentation (Healey and Schroy, North American segmentation)? METHODS Several embryological arguments and an analysis of anatomical data from a personal collection of 110 vasculobiliary casts were made. RESULTS Embryological arguments: Portal vein ...

BACKGROUND & AIMS The potential use of losartan, an angiotensin II type 1 receptor blocker, in the treatment of portal hypertension is still under debate. This randomized controlled trial compared the effects of losartan vs. propranolol on portal and systemic hemodynamics in patients with cirrhosis. METHODS Twenty-seven compensated patients were randomized to receive losartan 25 mg/day (n = 1...

BACKGROUND/AIM Endothelin-1 plays an important role in the regulation of portal hypertension; endothelin antagonists have been extensively studied in portal hypertensive animals. We aimed to evaluate the efficacy of highly selective endothelin antagonists in partial portal vein ligated (PPVL) rats. METHODS Four groups of 7 male Sprague-Dawley rats were administered orally ABT-627 (ET(A)-selec...

This study is aimed to investigate the effects of Sal B on portal hypertension (PH). PH with chronic hepatitis was induced by carbon tetrachloride (CCl(4)) in rats. The model was confirmed with elevated portal pressures and increased serum CD163 levels. The inducible nitric oxide synthase (iNOS) or heme oxygenase-1 (HO-1) in portal triads was assessed. The isolated portal perfused rat liver (IP...
