Arun Thenappan, Vivek Shukla, Feras J. Abdul Khalek, Ying Li, Kirti Shetty, Pu Liu, Lu Li, Randy L. Johnson, Lynt Johnson, Lopa Mishra – 14 December 2010 – Liver regeneration, following partial hepatectomy (PHx), occurs through precisely controlled and synchronized cell proliferation, in which quiescent hepatocytes undergo one to two rounds of replication, with restoration of liver mass and function. We previously demonstrated that loss of the Smad3/4 adaptor protein β‐2 spectrin (β2SP) is associated with faster entry into S phase, and hepatocellular cancer formation.

Kyu Sik Jung, Seung Up Kim, Sang Hoon Ahn, Young Nyun Park, Do Young Kim, Jun Yong Park, Chae Yoon Chon, Eun Hee Choi, Kwang‐Hyub Han – 14 December 2010 – Liver stiffness measurement (LSM) using FibroScan accurately assesses the degree of liver fibrosis and the risk of hepatocellular carcinoma (HCC) development in patients with chronic hepatitis C. This study investigated the usefulness of LSM as a predictor of HCC development in patients with chronic hepatitis B (CHB).

Tiangang Li, Michelle Matozel, Shannon Boehme, Bo Kong, Lisa‐Mari Nilsson, Grace Guo, Ewa Ellis, John Y. L. Chiang – 14 December 2010 – We reported previously that mice overexpressing cytochrome P450 7a1 (Cyp7a1; Cyp7a1‐tg mice) are protected against high fat diet–induced hypercholesterolemia, obesity, and insulin resistance. Here, we investigated the underlying mechanism of bile acid signaling in maintaining cholesterol homeostasis in Cyp7a1‐tg mice. Cyp7a1‐tg mice had two‐fold higher Cyp7a1 activity and bile acid pool than did wild‐type mice.

Hitendra Garg, Shiv Kumar Sarin, Manoj Kumar, Vishal Garg, Barjesh Chander Sharma, Ashish Kumar – 14 December 2010 – Spontaneous reactivation of chronic hepatitis B (CHB) is an important cause of acute‐on‐chronic liver failure (ACLF). Antiviral drugs may help reduce the high morbidity and mortality in such patients, especially in places where liver transplant is not available. The aim was to evaluate the efficacy of tenofovir and to determine the predictors of mortality in patients with spontaneous reactivation of CHB with ACLF.

Vicenzo Mazzaferro – 14 December 2010

Vivek Shukla, Cyrille Cuenin, Nileshkumar Dubey, Zdenko Herceg – 13 December 2010 – Organ regeneration after toxin challenge or physical injury requires a prompt and balanced cell‐proliferative response; a well‐orchestrated cascade of gene expression is needed to regulate transcription factors and proteins involved in cell cycle progression and cell proliferation.

Tetsuji Yoneyama, Katsuhiro Asonuma, Hideaki Okajima, Kwang‐Jong Lee, Hidekazu Yamamoto, Takayuki Takeichi, Yoshiharu Nakayama, Yukihiro Inomata – 13 December 2010 – In the clinical setting of living donor liver transplantation (LDLT), it is common to find a discrepancy between the graft volume estimated by preoperative computed tomography volumetry and the actual graft weight (AGW) measured on the back‐table. In this study, we attempt to find the coefficient factor that correlates the estimated graft volume to the AGW.

Dominique Thabut, Richard Moreau, Didier Lebrec – 13 December 2010 – Severe portal hypertension is responsible for complications and death. Although measurement of the hepatic venous pressure gradient is the most accurate method for evaluating the presence and severity of portal hypertension, this technique is considered invasive and is not routinely performed in all centers. Several noninvasive techniques have been proposed to measure portal hypertension.
