Cecília M. P. Rodrigues, Susana Solá, Dora Brites – 30 December 2003 – Increased levels of unconjugated bilirubin, the end‐product of heme catabolism, are detrimental to the central nervous system. To examine the role of apoptosis in bilirubin‐induced toxicity and to characterize the biochemical pathway of cell death, we exposed developing rat brain neurons to purified unconjugated bilirubin at concentrations below and above saturation of human serum albumin. Isolated neurons treated with bilirubin showed increased levels of apoptosis.

Hajime Honda, Kenichi Ikejima, Miyoko Hirose, Mutsuko Yoshikawa, Tie Lang, Nobuyuki Enomoto, Tsuneo Kitamura, Yoshiyuki Takei, Nobuhiro Sato – 30 December 2003 – In this study, we investigated hepatic fibrogenesis caused by long‐term thioacetamide (TAA) administration in ob/ob mice, a naturally occurring leptin deficient animal. In the lean littermates, prominent hepatic fibrosis, as well as positive staining for α smooth muscle actin (α‐SMA), was induced by treatment with TAA (200 μg/g, IP, 3 times per week) for 4 to 8 weeks as expected.

Gardner – 30 December 2003 – Elevated alanine transaminase (ALT) levels and low serum hepatitis B virus (HBV) DNA predict a higher likelihood of hepatitis B e antigen (HBeAg) loss in patients with chronic hepatitis B treated with interferon. Predictors of HBeAg loss in patients treated with lamivudine are not known.

Keiji Hirata, Jean‐François Dufour, Kazunori Shibao, Roy Knickelbein, Allison F. O'Neill, Hans‐Peter Bode, Doris Cassio, Marie V. St‐Pierre, Nicholas F. LaRusso, M. Fatima Leite, Michael H. Nathanson – 30 December 2003 – Cytosolic Ca2+ (Cai2+) regulates secretion of bicarbonate and other ions in the cholangiocyte. In other cell types, this second messenger acts through Ca2+ waves, Ca2+ oscillations, and other subcellular Ca2+ signaling patterns, but little is known about the subcellular organization of Ca2+ signaling in cholangiocytes.
