Terumi Takahara, Kei Furui, Jun Funaki, Yoshihide Nakayama, Hiroyuki Itoh, Chiharu Miyabayashi, Hiroshi Sato, Motoharu Seiki, Akira Ooshima, Akiharu Watanabe – 1 March 1995 – Matrix metalloproteinase‐II (MMP‐II, 72‐kd type IV collagenase, or gelatinase) is one of the gene families of zinc enzymes capable of degrading extracellular matrix molecules, and specifically of degrading type IV and V collagens, gelatin, fibronectin, and elastin.

Josep M. Barrera, Miguel Bruguera, M. Guadalupe Ercilla, Cristina Gil, Raquel Celis, M. Pilar Gil, M. Valle Del Onorato, Joan Rodés, Antoni Ordinas – 1 March 1995 – Persistent viremia after clinical or subclinical hepatitis C virus (HCV) infection is believed to occur in patients with chronic hepatitis C, but little is known about the duration of HCV replication in patients with acute hepatitis who have recovered or the relation of HCV viremia with the kinetics of antibodies to HCV (anti‐HCV).

Kenneth A. Somberg, John R. Lake, Stephen J. Tomlanovich, Jeanne M. Laberge, Vickie Feldstein, Nathan M. Bass – 1 March 1995 – Cirrhosis is frequently complicated by ascites that may become resistant to diuretic therapy. Transjugular intrahepatic portosystemic shunts (TIPS) represent a new treatment for this debilitating condition. The aim of this study was to ascertain the clinical efficacy of TIPS, as well as its impact on renal function and on hormonal parameters. Five inpatients with refractory ascites were studied prospectively before TIPS, and 3 and 14 days after TIPS.

Oliver Farges, Peter J. Morris, Margaret J. Dallman – 1 March 1995 – Liver allografts are not rejected in the fully incompatible Lewis‐RT11 (LEW) to blood group D Agouti‐RT1a (DA) rat strain combination despite an early infiltration by recipient mononucleated cells that initially display a phenotype, an ability to respond to interleukin‐2 (IL‐2) and donor‐specific cytotoxicity indistinguishable from that observed in the rejected, DA to LEW combination.

Frédéric Prat, Maria Centarti, Alain Sibille, Fatima Abou El Fadil, Luc Henry, Jean‐Yves Chapelon, Dominique Cathignol – 1 March 1995 – High‐Intensity Focused Ultrasound (HIFU) can produce radical tissue necrosis. We wanted to assess tumor destruction, proliferation, and tumorigenesis after HIFU, in an animal model of hepatic tumor. New Zealand rabbits bearing VX‐2 solitary liver tumors were treated with extracorporeal HIFU under ultrasound (US) guidance and standardized conditions. Groups differed only for the administration of either one or two consecutive HIFU procedures.

Kunitada Shimotohno – 1 March 1995 – We have built a model of the specificity pocket of the protease of hepatitis C virus on the basis of the known structures of trypsin‐like serine proteases and of the conservation pattern of the protease sequences among various hepatitis C strains. The model allowed us to predict that the substrate of this protease should have a cysteine residue in position P1. This hypothesis was subsequently proved by N‐terminal sequencing of two products of the protease.

Timothy D. Sielaff, Michael Y. Hu, Mark D. Rollins, Joseph R. Bloomer, Bruce Amiot, Wei‐Shou Hu, Frank B. Cerra – 1 March 1995 – A reproducible large animal model of fulminant hepatic failure was developed in the anesthetized dog by the administration of the amino sugar D‐galactosamine. Galactosamine in 5% dextrose in water (D5W), was given as an intravenous bolus to 10 young male dogs weighing 27 to 30 kg. Three dogs that received an equal volume of D5W alone served as controls.
