Higher Grades and Repeated Recurrence of Hepatic Encephalopathy May Be Related to High Serum Manganese Levels.

Hepatic encephalopathy is a serious complication of liver failure. Until now, the precise pathophysiologic mechanisms are not fully determined. It has been demonstrated that manganese plays an important role in the pathogenesis of hepatic encephalopathy.

Gastroenterologists and interventional radiologists: friends or foes? A multidisciplinary approach for solving gastrointestinal problems.

While endoscopy used to have more therapeutic abilities than radiology, interventional radiology is now racing to lead the minimally invasive diagnostic and therapeutic techniques in medicine as well as surgery. Expecting the new epidemic of hepatocellular carcinoma, radiologists and gastroenterologists are on the run competing in many procedures that are needed. While some radiologists worry about non-radiologists who "intervene" in radiology, many gastroenterologists defend their specialty.

GB virus C/hepatitis G virus in serum and liver of patients with chronic C and non B non C hepatitis: molecular and immunological aspects.

GB virus C/hepatitis G Virus (HGV) is a single-stranded RNA virus that is transmitted parenteraly. This study investigates GB virus C in 62 patients with chronic hepatitis C (CHC) and non B non C hepatitis (CNBNC). The viral E2 protein was examined in the sera of the patients (using western blott assay) while viral replication in the liver was examined by detecting the negative strand of HGV-RNA and its E2 protein in liver tissue using in situ hybridization and immunohistochemical staining respectively.
