Portal vein thrombus has been detected in patients with liver cirrhosis, pancreatitis, ulcerative colitis, septicemia, myeloproliferative disorder, and neoplasm. The formation of portal tumor thrombus by hepatocellular carcinoma is well recognized, because of its high incidence, and subsequent development of portal hypertension such as rupture of varices, ascites and liver failure indicates the...

The portal vein carries approximately 1 500ml/min of blood from the small and large bowel, spleen and stomach to the liver. Any obstruction or increased resistance to flow, or, rarely, pathological increases in portal blood flow, may lead to portal hypertension. The causes of portal hypertension are categorised as prehepatic, intrahepatic and posthepatic. Although the differential diagnosis is ...

User satisfaction with general information system (IS) and certain types of information technology (IT) applications has been thoroughly studied in IS research. With the widespread and increasing use of portal technology, however, there is a need to conduct a user satisfaction study on portal use -in particular, the business-to-employee (b2e) portal. In this paper, we propose a conceptual model...

Non-cirrhotic portal hypertension is an unusual but potentially serious liver disorder in human immunodeficiency virus-infected patients with prolonged exposure to didanosine. Due to its rarity, the diagnosis is often delayed. It is postulated that didanosine contributes to obliterative portal venopathy and causes portal hypertension. Affected patients may present with abnormal liver function o...

Previously we have shown that our routine portal imaging (PI) of the craniofacial region in pediatric brain tumor patients contributed an additional 2%-3% of the prescribed dose and up to 200 cGy to the planning target volume (PTV) and nearby organs at risk (OARs). The purpose of this study is to quantify the reduction in dose to PTV and OARs from portal imaging (PI) of the craniofacial region ...

Open Text’s acquisition of Vignette in July 2009 and Oracle’s pending acquisition of Sun Microsystems continue the horizontal portal market’s trend toward vendor consolidation. Most new horizontal portal projects are being launched based on a narrowing list of horizontal portal vendors. Some open-source horizontal portal and portal-as-a-service options provide alternatives for enterprises unwil...

We present a Grid Portal for solving satisfiability problems: http://orca.cs.ucsb.edu/sat portal . The portal provides a trivial interface which allows the use of a sophisticated and complex grid application GridSAT [6] running a large set of distributed computational resources hosted in different national computing centers. In this paper we describe the design goals of the portal and how it ha...

Portal hypertension (PHT) is a common and serious clinical syndrome often associated with chronic liver diseases. Portal hypertension may be defined as portal pressure gradients of 12 mmHg or more in the veins of the portal system caused by obstruction in the liver from intrahepatic or extrahepatic portal venous compression or occlusion (often associated with chronic liver disease), causing enl...

BACKGROUND Associating liver partition with portal vein ligation for staged hepatectomy induces more extensive liver hypertrophy than ligation alone; however, the mechanisms underlying the accelerated liver regrowth and the functional quality of the hypertrophic liver are presently elusive. This study, therefore, investigated the effect of parenchymal transection on liver volume and function af...
