Leticia Fernández, Nicolás Heredia, Luis Grande, Gloria Gómez, Antonio Rimola, Alberto Marco, Emilio Gelpí, Joan Roselló‐Catafau, Carmen Peralta – 30 December 2003 – This study was designed to evaluate whether ischemic preconditioning could confer protection against liver and lung damage associated with liver transplantation. The effect of preconditioning on the xanthine/xanthine oxidase (XOD) system in liver grafts subjected to 8 and 16 hours of cold ischemia was also evaluated.

Chandan Guha, Bhupesh Parashar, Niloy J. Deb, Madhur Garg, Giridhar R. Gorla, Anupam Singh, Namita Roy‐Chowdhury, Bhadrasain Vikram, Jayanta Roy‐Chowdhury – 30 December 2003 – The treatment of inherited metabolic liver diseases by hepatocyte transplantation (HT) would be greatly facilitated if the transplanted normal hepatocytes could be induced to proliferate preferentially over the host liver cells. We hypothesized that preparative hepatic irradiation (HIR) should inhibit host hepatocyte proliferation in response to partial hepatectomy (PH).

Florence Wong, Peter Liu, Laurence Blendis – 30 December 2003 – Renal sodium retention on standing is one aspect of the abnormal renal sodium handling in preascitic, well‐compensated patients with cirrhosis. Recently, it has been shown that low doses (7.5 mg) of the angiotensin II (Ang II) receptor antagonist, losartan, can reverse renal sodium retention on high, 200‐mmol sodium/d diet in these patients and restore them to sodium balance.

Noriatsu Kanno, Gene LeSage, Jo Lynne Phinizy, Shannon Glaser, Heather Francis, Gianfranco Alpini – 30 December 2003 – Growth factor signaling, mediated by the mitogen‐activated protein kinase (MAPK) cascade, induces cell mitosis. Adenosine 3',5'‐monophosphate (cAMP) may inhibit or stimulate mitosis (depending on the cell type) through the activation of MAPK and Raf proteins. Among Raf proteins, Raf‐1 and B‐Raf differentially regulate mitosis.

Aldo D. Mottino, Jingsong Cao, Luis M. Veggi, Fernando Crocenzi, Marcelo G. Roma, Mary Vore – 30 December 2003 – Estradiol‐17β‐D‐glucuronide (E217G), an endogenous metabolite of estradiol, induces a potent dose‐dependent and reversible inhibition of bile flow in the rat. We analyzed the effect of a single dose of E217G (15 μmol/kg, intravenously) to female rats on bile flow and the endocytic retrieval and function of the canalicular multidrug resistance‐associated protein 2 (Mrp2) and the effect of pretreatment with dibutyryl‐cyclic AMP (DBcAMP; 20 μmol/kg) on these measures.
