Furth, Luca Inverardi, Juan Dominguez‐Bendala, Camillo Ricordi, David Gerber, Eugenio Gaudio, Domenico Alvaro, Lola Reid – 2 December 2011 – Multipotent stem/progenitors are present in peribiliary glands of extrahepatic biliary trees from humans of all ages and in high numbers in hepato‐pancreatic common duct, cystic duct, and hilum.

Kathryn J. Fowler, Jeffrey J. Brown, Vamsi R. Narra – 2 December 2011 – This article is a review of magnetic resonance imaging (MRI) of incidental focal liver lesions. This review provides an overview of liver MRI protocol, diffusion‐weighted imaging, and contrast agents. Additionally, the most commonly encountered benign and malignant lesions are discussed with emphasis on imaging appearance and the diagnostic performance of MRI based on a review of the literature.

Kenneth E. Sherman, David L. Thomas, Raymond T. Chung – 2 December 2011 – Liver disease continues to represent a critical mediator of morbidity and mortality in those with human immunodeficiency virus (HIV) infection. The frequent presence and overlap of concomitant injurious processes, including hepatitis C virus and hepatitis B virus infections, hepatoxicity associated with antiretroviral therapeutic agents, alcohol, and other toxins, in the setting of immunosuppression lead to rapid fibrotic progression and early development of end‐stage liver disease.

Gulam H. Syed, Aleem Siddiqui – 2 December 2011 – Hepatitis C virus (HCV) relies on host lipid metabolic pathways for its replication, assembly, secretion, and entry. HCV induces de novo lipogenesis, inhibits β‐oxidation, and lipoprotein export resulting in a lipid‐enriched cellular environment critical for its proliferation. We investigated the effects of a hypolipidemic agent, nordihydroguaiaretic acid (NDGA), on host lipid/fatty acid synthesis and HCV life cycle. NDGA negated the HCV‐induced alteration of host lipid homeostasis.

Chun‐Ming Wong, Carmen Chak‐Lui Wong, Joyce Man‐Fong Lee, Dorothy Ngo‐Yin Fan, Sandy Leung‐Kuen Au, Irene Oi‐Lin Ng – 2 December 2011 – Hepatocellular carcinoma (HCC) is a prevalent cancer with an extremely high mortality rate attributed to HCC metastasis, which is the major cause of tumor recurrence and organ failure. Presence of tumor thrombi in the portal veins (venous metastases) is a clinicopathological feature of metastatic HCCs.
