During previous studies of susceptibility to hepatitis B virus (HBV) infection, HBV DNA was detected in 2/6 wild-caught baboons. In the present study, HBV DNA was amplified from 15/69 wild-caught baboons. All animals were negative for HBV surface antigen and antibody against HBV core antigen. Liver tissue from 1 baboon was immunohistochemically negative for HBV surface antigen but positive for ...

Hepatitis B (HBV) and C (HCV) viruses are major public health problems worldwide and are a serious cause of liver disease that may silently progress toward cirrhosis and hepatocellular carcinoma. The epidemiology of HBV and HCV infection in Morocco was studied. A large screening of HBsAg and HCVab was performed by third generation ELISA. Hepatitis B and C are parenterally transmitted with respe...

BACKGROUND The association between hepatitis B virus (HBV) mutations and hepatocarcinogenesis remains controversial because of conflicting data in the literature. We conducted a meta-analysis of case-control and cohort studies to examine HBV PreS, enhancer II (EnhII), basal core promoter (BCP), and precore mutations in relation to the risk of hepatocellular carcinoma (HCC). METHODS We searche...

In this article we study cooperative multi-choice games with limited cooperation possibilities, represented by an undirected forest on the player set. Players in the game can cooperate if they are connected in the forest. We introduce a new (single-valued) solution concept which is a generalization of the average tree solution defined and characterized by Herings et al. [2008] for TU-games play...
