Jeffrey B. Schwimmer, Cynthia Behling, Robert Newbury, Reena Deutsch, Caroline Nievergelt, Nicholas J. Schork, Joel E. Lavine – 22 August 2005 – Nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) are common in children and adolescents. However, standard histological criteria for pediatric NAFLD and NASH are undeveloped. We reviewed consecutive patients ages 2 to 18 years with biopsy‐proven NAFLD diagnosed between 1997 and 2003. Biopsies were evaluated by two pathologists for individual features of steatohepatitis.

Ruben R. Plentz, Brigitte Schlegelberger, Peer Flemming, Michael Gebel, Hans Kreipe, Michael P. Manns, K. Lenhard Rudolph, Ludwig Wilkens – 22 August 2005 – Chromosomal instability (CIN) leads to an increase in aneuploidy and chromosomal aberrations in human hepatocellular carcinoma (HCC). Telomere shortening appears as one mechanism fostering the development of CIN. Whether telomere shortening correlates to specific genetic changes that characterize a certain type of cancer has yet to be established.

Darius Moradpour, Volker Brass, Francois Penin – 22 August 2005 – Hepatitis C virus (HCV) is a human pathogen affecting nearly 3% of the world's population. Chronic infections can lead to cirrhosis and liver cancer. The RNA replication machine of HCV is a multi‐subunit membrane‐associated complex. The nonstructural protein NS5A is an active component of HCV replicase, as well as a pivotal regulator of replication and a modulator of cellular processes ranging from innate immunity to dysregulated cell growth.

Tracy Chen, Linda L. Pearce, Jim Peterson, Detcho Stoyanovsky, Timothy R. Billiar – 22 August 2005 – Nitric oxide (NO) can be either cytoprotective or cytotoxic in hepatocytes, depending on conditions within the cell. We hypothesized that redox status is a determinant of NO effects on cell viability.
