Sándor Paku, Peter Nagy, László Kopper, Snorri S. Thorgeirsson – 26 April 2004 – The 2‐acetylaminofluorene (AAF)/partial hepatectomy (PH) model is one of the most extensively studied experimental systems for oval cell proliferation and differentiation. We have previously described the oval cells as forming ductular structures surrounded by basement membrane, representing extensions of the canals of Hering. Herein we analyze the differentiation of oval cells into hepatocytes after varying degrees of liver damage induced by AAF.

Igor M. Sauer, Max Goetz, Ingo Steffen, Gesa Walter, Daniel C. Kehr, Ruth Schwartlander, Yoon J. Hwang, Andreas Pascher, Joerg C. Gerlach, Peter Neuhaus – 26 April 2004 – The detoxification capacities of single‐pass albumin dialysis (SPAD), the molecular adsorbents recirculation system, (MARS) and continuous veno‐venous hemodiafiltration (CVVHDF) were compared in vitro. In each experiment 4,100 mL of toxin‐loaded human plasma was processed for 6.5 hours. MARS treatment (n = 6) was undertaken in combination with CVVHDF.

Meagan J. Walsh, Daina M. Vanags, Andrew D. Clouston, Michelle M. Richardson, David M. Purdie, Julie R. Jonsson, Elizabeth E. Powell – 26 April 2004 – Steatosis is increasingly recognized as a cofactor influencing the progression of fibrosis in chronic hepatitis C; however, the mechanisms by which it contributes to liver injury remain uncertain.

Christopher E. P. Goldring, Neil R. Kitteringham, Robert Elsby, Laura E. Randle, Yuri N. Clement, Dominic P. Williams, Michael McMahon, John D. Hayes, Ken Itoh, Masayuki Yamamoto, B. Kevin Park – 26 April 2004 – The transcription factor NF‐E2‐related factor 2 (Nrf2) plays an essential role in the mammalian response to chemical and oxidative stress through induction of hepatic phase II detoxification enzymes and regulation of glutathione (GSH).

Jesús Medina, Alicia G. Arroyo, Francisco Sánchez‐Madrid, Ricardo Moreno‐Otero – 26 April 2004 – Intrahepatic hypoxia may occur during the inflammatory and fibrotic processes that characterize several chronic liver diseases of viral and autoimmune origin. As a consequence, new vascular structures are formed to provide oxygen and nutrients. Angiogenesis involves a tightly regulated network of cellular and molecular mechanisms that result in the formation of functional vessels.

Guruprasad P. Aithal, Lesley Ramsay, Ann K. Daly, Nhareet Sonchit, Julian B. S. Leathart, Graeme Alexander, J. Gerald Kenna, John Caldwell, Christopher P. Day – 26 April 2004 – Diclofenac is a nonsteroidal anti‐inflammatory drug that causes rare but serious hepatotoxicity, the mechanism of which is unclear. The purpose of the present study was to explore the potential role played by the immune processes.

Paul C. Adams, Michael J. Arthur, Thomas D. Boyer, Laurie D. DeLeve, Adrian M. Di Bisceglie, Mark Hall, Theodore R. Levin, Dawn Provenzale, Leonard Seeff – 26 April 2004 – This report summarizes an AASLD Clinical Workshop that was presented at Digestive Diseases Week 2003 on screening in liver diseases. As newer diagnostic tests become available, many liver diseases and complications of liver disease can be detected at an early asymptomatic stage. In many cases, early detection can lead to earlier treatment and an improved outcome.
