D E Jones, J V Metcalf, J D Collier, M F Bassendine, O F James – 30 December 2003 – In this study we have determined the incidence of hepatocellular carcinoma (HCC) development in primary biliary cirrhosis (PBC) and its effects on patient survival. Six hundred and sixty seven patients with liver histology compatible with or diagnostic of PBC were seen over a 20‐year period.

M Louha, K Poussin, N Ganne, H Zylberberg, B Nalpas, J Nicolet, F Capron, O Soubrane, C Vons, S Pol, M Beaugrand, P Berthelot, D Franco, J C Trinchet, C Brechot, P Paterlini – 30 December 2003 – The prognosis for patients with primary liver cancer (PLC) often depends on tumor recurrence and the development of extrahepatic metastases, particularly after liver transplantation. We have developed a sensitive test to detect both spontaneous circulation of tumor cells and the spread of liver cells due to chemoembolization and alcoholization.
Y Ilan, V K Jona, K Sengupta, A Davidson, M S Horwitz, N Roy‐Chowdhury, J Roy‐Chowdhury – 30 December 2003 – The host immune response limits the duration of expression of adenovirally transduced genes and precludes long‐term gene expression upon re‐administration of the virus. In this study we wished to evaluate whether short‐term immunosuppression of the host, at the time of recombinant virus administration, would allow expression of the therapeutic gene product upon virus reinjection. Gunn rats were used as recipients of recombinant adenoviruses expressing human BUGT (Ad‐hBUGT) or E.
T Kawahara, S Kasai, H Yagita, M Sawa, K Kato, M Azuma, A Nakajima, K Okumura, S Futagawa, M Mito – 30 December 2003 – Cytolytic induction of T cells requires both the T‐cell receptor (TCR)‐mediated antigenic stimulation and the CD28‐mediated co‐stimulatory signal. Blockade of the interactions between CD28 and its ligands, CD80 and CD86, prolongs the survival of allografts in some transplantation models.
M L Shiffman, C M Hofmann, E B Thompson, A Ferreira‐Gonzalez, M J Contos, A Koshy, V A Luketic, A J Sanyal, A S Mills, C T Garrett – 30 December 2003 – The present study was conducted to evaluate the relationship between biochemical, virological, and histological response during the course of interferon therapy. Ninety consecutive patients with well‐documented chronic hepatitis C virus (HCV) were treated with 5 MU of interferon alfa‐2b three times weekly for 6 months. Liver biopsy was performed, and serum HCV RNA titer was measured before and at the completion of interferon treatment.
H Nakano, H Nagasaki, A Barama, K Boudjema, D Jaeck, K Kumada, M Tatsuno, Y Baek, N Kitamura, T Suzuki, M Yamaguchi – 30 December 2003 – Abundant fat in the liver has been implicated in poor outcome after liver transplantation or liver surgery, but the reasons for this association are still unclear. The aim of the present study was to examine mechanisms that may be involved in hepatic dysfunction after ischemia‐reperfusion (I/R) of the steatotic rat liver. Steatosis was produced by a choline‐methionine‐deficient (CMDD) diet.
J Napoli, D Prentice, C Niinami, G A Bishop, P Desmond, G W McCaughan – 30 December 2003 – Chronic hepatic regeneration constitutes an important part of the cirrhotic process. The factors regulating chronic hepatic regeneration, however, remain unclear.
A Tsukahara, S Seki, T Iiai, T Moroda, H Watanabe, S Suzuki, T Tada, H Hiraide, K Hatakeyama, T Abo – 30 December 2003 – Mouse liver contains both IL‐2Rβ‐ (or low positive) high T‐cell receptor (TCR(hi)) cells and IL‐2Rβ+ intermediate TCR (TCR(int)) cells. TCR(int) cells consist of natural killer 1.1 (NK1)+ and NK1‐ subsets. NK1‐ TCR(int) cells increase constantly with age whereas TCR(hi) cells decrease. NK1+ TCR(int) cell proportions in the liver increase until middle age and decrease thereafter.
