Rolando Hernández‐Muñoz, Mauricio Díaz‐Muñoz, Juan A. Suárez‐Cuenca, Cristina Trejo‐Solís, Verónica López, Lourdes Sánchez‐Sevilla, Lucía Yáñez, Victoria Chagoya De Sánchez – 30 December 2003 – Cirrhosis is one of the most common causes of mortality worldwide, because hepatic dysfunction constitutes a potentially lethal condition. Having demonstrated the hepatoprotective effect of adenosine against CCl4‐induced cirrhosis, the present study was aimed at assessing adenosine's effect on an already‐established micronodular cirrhosis.

Motoko Sasaki, Judy Van De Water, Thomas P. Kenny, Michael L. Gallo, Patrick S. C. Leung, Yasuni Nakanuma, Aftab A. Ansari, Ross L. Coppel, James Neuberger, M. Eric Gershwin – 30 December 2003 – The immunodominant antimitochondrial antibody (AMA) response in primary biliary cirrhosis (PBC) is directed against the E2 component of pyruvate dehydrogenase (PDC‐E2).

Shinichi Ueno, Gen Tanabe, Katsumi Sako, Takuya Hiwaki, Hirohumi Hokotate, Yoshihiko Fukukura, Yoshirou Baba, Yasushi Imamura, Takashi Aikou – 30 December 2003 – To reliably estimate the prognoses of patients with hepatocellular carcinoma (HCC), both liver function and tumor‐related factors should be accounted for. However, there are few worldwide staging systems that assess prognostic value in the context of selecting individual patients for randomized stratification in therapeutic and clinical trials.

Emanuela Cova, Ai‐Yu Gong, Raul A. Marinelli, Nicholas F. LaRusso – 30 December 2003 – In recent studies using freshly isolated rat cholangiocytes, we established that water crosses the cholangiocyte membrane by a channel‐mediated mechanism involving aquaporins, a family of water‐channel proteins. Our goal was to address the importance of channel‐mediated water transport in ductal bile formation by employing a physiologic experimental model, the enclosed, polarized rat intrahepatic bile duct unit (IBDU).

Hsiang Ju Lin, Leonard B. Seeff, Luiz Barbosa, F. Blaine Hollinger – 30 December 2003 – A total of 240 stored serum specimens from 30 transfusion recipients and 120 blood donors from the Transfusion‐Transmitted Viruses Study (TTVS) were evaluated with the objective of establishing transmission of hepatitis C virus (HCV) by specific blood donors. Phylogenetic analysis of hypervariable region 1 (HVR1) and HCV genotyping were performed on the genomic region encoding amino acids 329 to 410. Amino acid distances between HVR1 sequences were calculated by the Kimura formula.

Kenichi Ikejima, Hajime Honda, Mutsuko Yoshikawa, Miyoko Hirose, Tsuneo Kitamura, Yoshiyuki Takei, Nobuhiro Sato – 30 December 2003 – Lines of evidence suggested a possible link between leptin and hepatic fibrosis; however, whether leptin modulates the fibrogenesis in the liver remains unclear. The purpose of this study, therefore, was to evaluate the effect of leptin on inflammatory and profibrogenic responses in the liver caused by hepatotoxic chemicals.

Tuan H. Vu, Kurenai Tanji, Stephen A. Holve, Eduardo Bonilla, Ronald J. Sokol, Russell D. Snyder, Stephany Fiore, Gail H. Deutsch, Salvatore DiMauro, Darryl De Vivo – 30 December 2003 – Navajo neurohepatopathy (NNH) is an autosomal recessive disease of full‐blooded Navajo children living in the Navajo Reservation of southwestern United States. Clinical features of NNH include peripheral and central nervous system involvement, acral mutilation, corneal scarring or ulceration, liver failure, and metabolic and immunologic derangement.

Miguel R. Arguedas, Anita Johnson, Mohamad A. Eloubeidi, Michael B. Fallon – 30 December 2003 – Hepatitis A virus (HAV) vaccination is recommended in chronic liver disease because of an increased morbidity and mortality associated with HAV superinfection. However, data regarding the efficacy of HAV vaccination in patients with advanced chronic liver disease is limited. We assessed the efficacy of a standard HAV vaccination schedule in decompensated chronic liver disease in comparison with compensated disease and defined clinical predictors associated with seroconversion.
