Harm Hoekstra, Carlijn I. Buis, Robert C. Verdonk, Christian S. van der Hilst, Eric J. van der Jagt, Elizabeth B. Haagsma, Robert J. Porte – 29 July 2009 – Biliary reconstruction using Roux‐en‐Y choledochojejunostomy has been suggested as a risk factor for the development of nonanastomotic biliary strictures (NAS) after liver transplantation. Roux‐en‐Y reconstruction, however, is preferentially used in patients transplanted for primary sclerosing cholangitis (PSC), and the disease itself is also associated with a higher incidence of NAS.

André A. S. Dick, Austin L. Spitzer, Catherine F. Seifert, Alysun Deckert, Robert L. Carithers, Jorge D. Reyes, James D. Perkins – 29 July 2009 – Controversies exist regarding the morbidity and mortality of patients undergoing liver transplantation at the extremes of the body mass index (BMI). A review of the United Network for Organ Sharing database from 1987 through 2007 revealed 73,538 adult liver transplants.

Leo L. Studach, Lova Rakotomalala, Wen‐Horng Wang, Ronald L. Hullinger, Stefano Cairo, Marie‐Annick Buendia, Ourania M. Andrisani – 29 July 2009 – Chronic hepatitis B virus (HBV) infection is linked to development of hepatocellular carcinoma (HCC). The HBV X protein (pX) is implicated in HCC pathogenesis acting as a weak oncogene or a cofactor in hepatocarcinogenesis. pX induces DNA re‐replication, DNA damage, and partial polyploidy in a poorly differentiated, immortalized hepatocyte cell line.

Herdis Bender, Monique Y. Wiesinger, Carolin Nordhoff, Caroline Schoenherr, Claude Haan, Stephan Ludwig, Ralf Weiskirchen, Nobuyuki Kato, Peter C. Heinrich, Serge Haan – 29 July 2009 – Interleukin‐27 (IL‐27) is a cytokine belonging to the IL‐6/IL‐12 cytokine family. It is secreted by antigen‐presenting cells, strongly acts on T cells, and also stimulates innate immune cells. In most studies, the effects of IL‐27 on T cells were investigated; however, not much is known about possible effects of IL‐27 on other cell types.

Lu, M. Luz Martínez‐Chantar, José M. Mato – 29 July 2009 – Hepatic S‐adenosylmethionine (SAMe) is maintained constant by the action of methionine adenosyltransferase I/III (MATI/III), which converts methionine into SAMe and glycine N‐methyltransferase (GNMT), which eliminates excess SAMe to avoid aberrant methylation reactions.
