Omar Cauli, Regina Rodrigo, Blanca Piedrafita, Jordi Boix, Vicente Felipo – 27 July 2007 – One of the neurological alterations in patients with minimal or overt hepatic encephalopathy is cognitive impairment. This impairment is reproduced in rats with chronic liver failure due to portacaval shunt (PCS). These rats show decreased ability to learn a conditional discrimination task in a Y‐maze, likely due to reduced function of the glutamate–nitric oxide (NO)–cyclic guanosine monophosphate (cGMP) pathway in brain.

Hong‐Lei Weng, Loredana Ciuclan, Yan Liu, Jafar Hamzavi, Patricio Godoy, Haristi Gaitantzi, Stefan Kanzler, Rainer Heuchel, Uwe Ueberham, Rolf Gebhardt, Katja Breitkopf, Steven Dooley – 26 July 2007 – Connective tissue growth factor (CTGF) is important for transforming growth factor‐β (TGF‐β)–induced liver fibrogenesis. Hepatic stellate cells have been recognized as its major cellular source in the liver. Here we demonstrate the induction of CTGF expression in hepatocytes of damaged livers and identify a molecular mechanism responsible for it.

Katja Derkow, Christoph Loddenkemper, Justine Mintern, Nils Kruse, Katja Klugewitz, Thomas Berg, Bertram Wiedenmann, Hidde L. Ploegh, Eckart Schott – 26 July 2007 – The pathogenesis of autoimmune liver diseases is poorly understood. Animal models are necessary to investigate antigen presentation and priming of T‐cells in the context of autoimmunity in the liver. Transgenic mouse models were generated in which the model antigen ovalbumin is expressed in hepatocytes (TF‐OVA) or cholangiocytes (ASBT‐OVA).

Yen‐Shen Lu, Yoko Kashida, Samuel K. Kulp, Yu‐Chieh Wang, Dasheng Wang, Jui‐Hsiang Hung, Monica Tang, Zhong‐Zhe Lin, Te‐Jung Chen, Ann‐Lii Cheng, Ching‐Shih Chen – 25 July 2007 – Hepatocellular carcinoma (HCC) is a leading cause of cancer death worldwide, yet effective therapeutic options for advanced HCC are limited. This study was aimed at assessing the antitumor effect of a novel phenylbutyrate‐derived histone deacetylase (HDAC) inhibitor, OSU‐HDAC42, vis‐à‐vis suberoylanilide hydroxamic acid (SAHA), in in vitro and in vivo models of human HCC.

Patricia E. Ganey, James P. Luyendyk, Sandra W. Newport, Theresa M. Eagle, Jane F. Maddox, Nigel Mackman, Robert A. Roth – 25 July 2007 – Acetaminophen (N‐acetyl‐p‐aminophenol [APAP]) is one of the leading causes of acute liver failure, and APAP hepatotoxicity is associated with coagulopathy in humans. We tested the hypothesis that activation of the coagulation system and downstream protease‐activated receptor (PAR)‐1 signaling contribute to APAP‐induced liver injury.

Jordan J. Feld, Melissa Ayers, Dahlia El‐Ashry, Tony Mazzulli, Raymond Tellier, E. Jenny Heathcote – 25 July 2007 – After hepatitis B e antigen (HBeAg) seroconversion, hepatitis B may become inactive or progress to HBeAg‐negative hepatitis with persistent or intermittent alanine aminotransferase (ALT) elevation. The aim of this study was to prospectively identify factors predictive of the clinical course in HBeAg‐negative chronic hepatitis B (CHB). Patients were stratified by ALT and HBeAg status and followed every 3 months for up to 5 years.

Puneet Puri, Rebecca A. Baillie, Michelle M. Wiest, Faridoddin Mirshahi, Jayanta Choudhury, Onpan Cheung, Carol Sargeant, Melissa J. Contos, Arun J. Sanyal – 25 July 2007 – The spectrum of nonalcoholic fatty liver disease (NAFLD) includes a nonalcoholic fatty liver (NAFL) and nonalcoholic steatohepatitis (NASH). The specific types and amounts of lipids that accumulate in NAFLD are not fully defined.

Maureen M. J. Guichelaar, Jeffrey Schmoll, Michael Malinchoc, J. Eileen Hay – 25 July 2007 – With early posttransplant bone loss, orthotopic liver transplantation (OLT) recipients experience a high rate of fracturing and some avascular necrosis (AVN), but little is known about the incidence of and predictive factors for these skeletal complications.
