Kwang‐Woong Lee, Jae Won Joh, Sung Joo Kim, Seong Ho Choi, Jin Seok Heo, Hwan Hyo Lee, Jean Wan Park, Suk‐Koo Lee – 30 August 2004 – Biliary complications after living donor liver transplantation (LDLT) continue to be problematic. For reducing the biliary complications, the authors applied an intrahepatic Glissonian approach to the recipient hepatectomy. We called this Glissonian dissection technique at the high hilar level high hilar dissection (HHD). In this study, we introduced this HHD technique and evaluated its outcome in 31 recipients of a living donor liver transplant (LDLT).

Anna Feliu, Eugeni Gay, Montserrat García‐Retortillo, Juan Carlos Saiz, Xavier Forns – 30 August 2004 – Liver cirrhosis caused by chronic hepatitis C virus (HCV) infection is the main indication for liver transplantation (LT). There is little information on HCV genetic evolution following transplantation. The aim of this study was to carefully assess early evolution of HCV quasispecies in a cohort of 18 liver transplant recipients followed prospectively.

Renate G. van der Molen, Dave Sprengers, Rekha S. Binda, Esther C. de Jong, Hubert G. M. Niesters, Johannes G. Kusters, Jaap Kwekkeboom, Harry L. A. Janssen – 30 August 2004 – Dendritic cells (DC) play an important role in the induction of T‐cell responses. We hypothesize that the hampered antiviral T‐cell response in chronic hepatitis B patients is a result of impaired dendritic cell function.

Aránzazu Sánchez, Valentina M. Factor, Luis A. Espinoza, Insa S. Schroeder, Snorri S. Thorgeirsson – 30 August 2004 – Hepatic stem cells are activated after liver damage and have a critical role in tissue homeostasis and repair. Characterization of molecular and cellular events accompanying the expansion and differentiation of liver stem cells is essential for understanding the basic biology of stem cells and for facilitating clinical application of the stem cells.

Akihide Kamiya, Frank J. Gonzalez – 30 August 2004 – Fetal hepatic maturation consists of multisteps and is regulated by several cytokines and cell–cell or cell–matrices interactions. In the mid‐to‐late fetal stage, hepatocytes have few metabolic functions associated with adult liver homeostasis. Cultured fetal hepatocytes acquire the expression of several mature liver‐specific genes through stimulation with hepatic maturation factor oncostatin M (OSM) and matrigel. Tumor necrosis factor‐α (TNFα) regulates fetal hepatic maturation stimulated by OSM and matrigel.

Natalia A. Osna, James Haorah, Viatcheslav M. Krutik, Terrence M. Donohue – 30 August 2004 – The proteasome is an important multicatalytic enzyme complex that degrades misfolded and oxidized proteins, signal transduction factors, and antigenic peptides for presentation. We investigated the in vitro effects of peroxynitrite (PN) on the peptidase activity of both crude 20S and 26S and purified 20S proteasome preparations from rat liver as well as proteasome activity in Hep G2 cells and in mouse liver.

Kyrsten D. Fairbanks, Paul J. Thuluvath – 30 August 2004 – The long‐term use of calcineurin inhibitors (CIs) is associated with significant morbidity in liver transplant recipients. Although mycophenolate mofetil (MMF) is well tolerated, two small studies reported an unacceptable rate of acute allograft rejection in liver transplant recipients receiving MMF monotherapy. In this study, we retrospectively investigated the safety and efficacy of MMF monotherapy in liver transplant recipients. We reviewed the medical records of all patients who underwent liver transplant at our institution.

Raymond Reding, Hugh F.S. Davies – 30 August 2004 – Ever since the demonstration that allografts are rejected through immune reactions of the host, clinical therapies for organ allografts have relied on immune suppression to prevent these destructive events. A growing body of clinical and experimental data suggests that allografts elicit multiple, interactive immune responses. The result is not inevitably graft rejection, and “spontaneous” acceptance of fully allogeneic liver grafts occurs in rodents without immunosuppression.
