Silja Kosola, Hanna Lampela, Hannu Jalanko, Heikki Mäkisalo, Jouko Lohi, Johanna Arola, Mikko P. Pakarinen – 29 October 2012 – Controversy remains about the role of protocol liver biopsy for symptom‐free recipients and about the long‐term use of low‐dose steroids after pediatric liver transplantation (LT). We conducted a national cross‐sectional study of pediatric recipients who underwent LT between 1987 and 2007.

Jeffrey B. Halldorson, Harry J. Paarsch, Jennifer L. Dodge, Alberto M. Segre, Jennifer Lai, John Paul Roberts – 19 October 2012 – In the United States, livers for transplantation are distributed within donation service areas (DSAs). In DSAs with multiple transplant centers, competition among centers for organs and recipients may affect recipient selection and outcomes in comparison with DSAs with only 1 center. The objective of this study was to determine whether competition within a DSA is associated with posttransplant outcomes and variations in patients wait‐listed within the DSA.

Yun Wang, Luyong Zhang, Xudong Wu, Emily C. Gurley, Elaine Kennedy, Phillip B. Hylemon, William M. Pandak, Arun J. Sanyal, Huiping Zhou – 18 October 2012 – Human immunodeficiency virus (HIV) protease inhibitors (HIV PIs) are the core components of highly active antiretroviral therapy, which has been successfully used in the treatment of HIV‐1 infection in the past two decades. However, benefits of HIV PIs are compromised by clinically important adverse effects, such as dyslipidemia, insulin resistance, and cardiovascular complications.

Jeong Kyu Kim, Ji Heon Noh, Kwang Hwa Jung, Jung Woo Eun, Hyun Jin Bae, Min Gyu Kim, Young Gyoon Chang, Qingyu Shen, Won Sang Park, Jung Young Lee, Jürgen Borlak, Suk Woo Nam – 18 October 2012 – Sirtuins are nicotinamide adenine dinucleotide oxidized form (NAD+)‐dependent deacetylases and function in cellular metabolism, stress resistance, and aging. For sirtuin7 (SIRT7), a role in ribosomal gene transcription is proposed, but its function in cancer has been unclear.

Luis Fontana, Enpeng Zhao, Muhammad Amir, Hanqing Dong, Kathryn Tanaka, Mark J. Czaja – 18 October 2012 – The prevalence of the metabolic syndrome and nonalcoholic fatty liver disease (NAFLD) in humans increases with age. It is unknown whether this association is secondary to the increased incidence of risk factors for NAFLD that occurs with aging, reflects the culmination of years of exposure to lifestyle factors such as a high‐fat diet (HFD), or results from physiological changes that characterize aging.

Elizabeth C. Verna, Rita Abdelmessih, Marcela A. Salomao, Jay Lefkowitch, Roger K. Moreira, Robert S. Brown – 18 October 2012 – Cholestatic hepatitis C virus (HCV) is a rare form of recurrent HCV following liver transplantation (LT) without specific diagnostic criteria. An outcome‐based method to improve its diagnosis and a description of its prognosis are needed.

Silvia Giordano, Amedeo Columbano – 18 October 2012 – MicroRNAs (miRNAs) are evolutionarily conserved small noncoding RNAs involved in the regulation of gene expression and protein translation. Many studies have shown that they play a crucial role in driving organ and tissue differentiation during embryogenesis and in the fine‐tuning of fundamental biological processes, such as proliferation and apoptosis. Growing evidence indicates that their deregulation plays an important role in cancer onset and progression as well, where they act as oncogenes or oncosuppressors.
