Pavel Taimr, Hajime Higuchi, Eva Kocova, Richard A. Rippe, Scott Friedman, Gregory J. Gores – 30 December 2003 – Apoptosis has emerged as an important mechanism to reduce numbers of activated stellate cells during the resolution phase of hepatic fibrosis. These observations suggest that activated stellate cells may be more susceptible to apoptotic stimuli than their quiescent counterparts.

Qi Qian, Airong Li, Bernard F. King, Patrick S. Kamath, Donna J. Lager, John Huston, Clarence Shub, Sonia Davila, Stefan Somlo, Vicente E. Torres – 30 December 2003 – Most reports on the natural history, manifestations, and treatment of polycystic liver disease are based on the disease as it manifests in patients with autosomal dominant polycystic kidney disease (ADPKD). The purpose of this study was to develop a clinical profile of isolated autosomal dominant polycystic liver disease (ADPLD) using nonaffected family members as controls.

The aim of the present study was to assess both morphologic and functional alterations in the mitochondria of troglitazone‐treated hepatocytes. A polarized human hepatocyte cell line, OUMS‐29, was used in this study.

Rita Carini, Maria Grazia De Cesaris, Roberta Splendore, Cinzia Domenicotti, Maria Paola Nitti, Maria Adelaide Pronzato, Emanuele Albano – 30 December 2003 – Atrial natriuretic peptide (ANP) reduces ischemia and/or reperfusion damage in several organs, but the mechanisms involved are largely unknown. We used freshly isolated rat hepatocytes to investigate the mechanisms by which ANP enhances hepatocyte resistance to hypoxia.

Agustín Albillos, Antonio de la Hera, Mónica González, Jose‐Luis Moya, Jose‐Luis Calleja, Jorge Monserrat, Luis Ruiz‐del‐Arbol, Melchor Alvarez‐Mon – 30 December 2003 – Intestinal bacterial overgrowth and translocation, both common in cirrhosis with ascites, may lead to the activation of monocytes and lymphocytes, increased levels of proinflammatory cytokines, and enhanced synthesis of nitric oxide present in cirrhosis. Bacterial endotoxin promotes the synthesis of lipopolysaccharide (LPS)‐binding protein (LBP), and forms a LPS‐LBP complex that binds to CD14.

Rolf J. Schauer, Alexander L. Gerbes, Daniel Vonier, Mark op den Winkel, Peter Fraunberger, Manfred Bilzer – 30 December 2003 – Ischemic preconditioning (IP) triggers protection of the liver from prolonged subsequent ischemia. However, the underlying protective mechanisms are largely unknown. We investigated whether and how IP protects the liver against reperfusion injury caused by Kupffer cell (KC)‐derived oxidants.

Atsushi Kato, Tomohisa Okaya, Alex B. Lentsch – 30 December 2003 – Hepatic ischemia/reperfusion injury involves a complex inflammatory cascade resulting in neutrophil‐mediated injury of hepatocytes. Previous studies from our laboratory have established that exogenous administration of the anti‐inflammatory cytokines interleukin 10 (IL‐10) and IL‐13 can ameliorate the inflammatory response and significantly reduce hepatocellular injury.
