Screening for Wilson disease in acute liver failure: A comparison of currently available diagnostic tests

Jessica D. Korman, Irene Volenberg, Jody Balko, Joe Webster, Frank V. Schiodt, Robert H. Squires, Robert J. Fontana, William M. Lee, Michael L. Schilsky, Pediatric and Adult Acute Liver Failure Study Groups – 26 September 2008 – Acute liver failure (ALF) due to Wilson disease (WD) is invariably fatal without emergency liver transplantation. Therefore, rapid diagnosis of WD should aid prompt transplant listing.

Calcium influx mechanisms underlying calcium oscillations in rat hepatocytes

Bertina F. Jones, Rebecca R. Boyles, Sung‐Yong Hwang, Gary S. Bird, James W. Putney – 26 September 2008 – The process of capacitative or store‐operated Ca2+ entry has been extensively investigated, and recently two major molecular players in this process have been described. Stromal interacting molecule (STIM) 1 acts as a sensor for the level of Ca2+ stored in the endoplasmic reticulum, and Orai proteins constitute pore‐forming subunits of the store‐operated channels.

Surface markers for the murine oval cell response

Craig Dorrell, Laura Erker, Kelsea M. Lanxon‐Cookson, Stephanie L. Abraham, Tristan Victoroff, Simon Ro, Pamela S. Canaday, Philip R. Streeter, Markus Grompe – 26 September 2008 – The biology of progenitor activation in the liver is of considerable medical and scientific interest. The powerful genetic tools available for the mouse make it an ideal model system to study this complex process involving many different cell types. However, reagents for the isolation and study of distinct hepatic subpopulations have been quite limited compared to those available for hematopoietic cells.

A mutation in the canalicular phospholipid transporter gene, ABCB4, is associated with cholestasis, ductopenia, and cirrhosis in adults

Daniel Gotthardt, Heiko Runz, Verena Keitel, Christine Fischer, Christa Flechtenmacher, Michael Wirtenberger, Karl Heinz Weiss, Sandra Imparato, Annika Braun, Kari Hemminki, Wolfgang Stremmel, Franz Rüschendorf, Adolf Stiehl, Ralf Kubitz, Barbara Burwinkel, Peter Schirmacher, A. S. Knisely, Johannes Zschocke, Peter Sauer – 26 September 2008 – Cholestatic liver disease (CLD) is a major cause of progressive liver damage and liver failure. Several forms of biliary cirrhosis are caused by mutations in specific genes.

Hepatitis C is a predictor of acute liver injury among hospitalizations for acetaminophen overdose in the United States: A nationwide analysis

Geoffrey C. Nguyen, Justina Sam, Paul J. Thuluvath – 26 September 2008 – Acute liver injury (ALI) following acetaminophen overdose (AO) occurs in less than 10% of cases, but that risk is increased among alcoholics and those with chronic alcoholic liver disease. We sought to assess whether coexistent hepatitis C virus (HCV) infection potentiated the hepatotoxic effects of acetaminophen. We queried the Nationwide Inpatient Sample (1998‐2005), a 20% sample of U.S.

Bone marrow–derived immune cells mediate sensitization to liver injury in a myeloid differentiation factor 88–dependent fashion

Istvan Hritz, Arumugam Velayudham, Angela Dolganiuc, Karen Kodys, Pranoti Mandrekar, Evelyn Kurt‐Jones, Gyongyi Szabo – 26 September 2008 – Toll‐like receptors (TLRs) expressed on both immune cells and hepatocytes recognize microbial danger signals and regulate immune responses. Previous studies showed that TLR9 and TLR2 mediate Propionibacterium acnes–induced sensitization to lipopolysaccharide‐triggered acute liver injury in mice. Ligand‐specific activation of TLR2 and TLR9 are dependent on the common TLR adaptor, myeloid differentiation factor 88 (MyD88).

Functional magnetic resonance imaging monitoring of pathological changes in rodent livers during hyperoxia and hypercapnia

Hila Barash, Eitan Gross, Yifat Edrei, Orit Pappo, Gadi Spira, Israel Vlodavsky, Eithan Galun, Idit Matot, Rinat Abramovitch – 26 September 2008 – Liver diseases and regeneration are associated with hemodynamic changes denoting pathological alterations. Determining and monitoring physiological and pathological liver changes is essential for diagnostic and therapeutic objectives. Our aim was to determine the feasibility of functional magnetic resonance imaging (fMRI) during hypercapnia and hyperoxia for monitoring liver pathology.

The hepatic apelin system: A new therapeutic target for liver disease

Alessandro Principe, Pedro Melgar‐Lesmes, Guillermo Fernández‐Varo, Luis Ruiz del Arbol, Josefa Ros, Manuel Morales‐Ruiz, Mauro Bernardi, Vicente Arroyo, Wladimiro Jiménez – 26 September 2008 – Apelin is a peptide that plays an important role in heart physiology and pathophysiology, inflammation, and angiogenesis. We evaluated whether the endogenous apelin system is involved in the pathogenesis of the hepatic remodeling and cardiovascular and renal complications occurring in advanced liver disease.
