Jae‐Hwi Jang, Andreas Rickenbacher, Bostjan Humar, Achim Weber, Dimitri Aristotle Raptis, Kuno Lehmann, Bruno Stieger, Wolfgang Moritz, Christopher Soll, Panco Georgiev, David Fischer, Endre Laczko, Rolf Graf, Pierre‐Alain Clavien – 30 January 2012 – Obstructive cholestasis induces liver injury, postoperative complications, and mortality after surgery. Adaptive control of cholestasis, including bile salt homeostasis, is necessary for recovery and survival. Peripheral serotonin is a cytoprotective neurotransmitter also associated with liver regeneration.

Kenichi Harada, Shinji Shimoda, Yasushi Kimura, Yasunori Sato, Hiroko Ikeda, Saya Igarashi, Xiang‐Shan Ren, Hirohide Sato, Yasuni Nakanuma – 30 January 2012 – IgG4 reactions consisting of marked infiltration by immunoglobulin G4 (IgG4)‐positive plasma cells in affected organs is found in cancer patients as well as patients with IgG4‐related diseases. Notably, extrahepatic cholangiocarcinomas accompanying marked IgG4 reactions clinicopathologically mimic IgG4‐related sclerosing cholangitis.

Caroline Scholtes, Christophe Ramière, Dominique Rainteau, Laure Perrin‐Cocon, Claude Wolf, Lydie Humbert, Martine Carreras, Aurélie Guironnet‐Paquet, Fabien Zoulim, Ralf Bartenschlager, Vincent Lotteau, Patrice André, Olivier Diaz – 30 January 2012 – Hepatitis C virus (HCV) particles associate viral and lipoprotein moieties to form hybrid lipoviral particles (LVPs). Cell culture–produced HCV (HCVcc) and ex vivo–characterized LVPs primarily differ by their apolipoprotein (apo) B content, which is low for HCVcc, but high for LVPs.

Sarwa Darwish Murad, W. Ray Kim, Terry Therneau, Gregory J. Gores, Charles B. Rosen, James A. Martenson, Steven R. Alberts, Julie K. Heimbach – 30 January 2012 – We have previously reported excellent outcomes with liver transplantation for selected patients with early‐stage perihilar cholangiocarcinoma (CCA) following neoadjuvant chemoradiotherapy. Our aim was to identify predictors of dropout before transplantation and predictors of cancer recurrence after transplantation.

Haofeng Ji, Xiu‐da Shen, Yu Zhang, Feng Gao, Cynthia Y. Huang, William W. Chang, Coney Lee, Bibo Ke, Ronald W. Busuttil, Jerzy W. Kupiec‐Weglinski – 30 January 2012 – Hepatic ischemia/reperfusion injury (IRI) occurs in multiple clinical settings, including liver transplantation. The cyclic adenosine monophosphate (cAMP)–dependent protein kinase A (PKA) pathway inhibits hepatocellular apoptosis and regulates toll‐like receptor 4–triggered inflammation responses in vitro.

Sanjeev K. Akkina, Sumeet K. Asrani, Yi Peng, Peter Stock, W. Ray Kim, Ajay K. Israni – 28 January 2012 – Because of the shortage of deceased donor organs, transplant centers accept organs from marginal deceased donors, including older donors. Organ‐specific donor risk indices have been developed to predict graft survival with various combinations of donor and recipient characteristics. Here we review the kidney donor risk index (KDRI) and the liver donor risk index (LDRI) and compare and contrast their strengths, limitations, and potential uses.
