Arsenic is a well-documented human carcinogen, and contamination with this heavy metal is of global concern, presenting a major issue in environmental health. However, the mechanism by which arsenic induces cancer is unknown, in large part due to the lack of an appropriate animal model. In the present set of experiments, we focused on dimethylarsinic acid(More)
Although histopathological examination by “invasive” liver biopsy remains the gold standard for evaluating disease progression in chronic liver disease, noninvasive tools have appeared and have led to great progress in diagnosing the stage of hepatic fibrosis. The aim of this study was to assess the value of real-time tissue elastography, using an(More)
AIM Percutaneous radiofrequency ablation (P-RFA) therapy is a widely applied treatment for small hepatocellular carcinoma (HCC); however, local recurrence is a major issue of HCC located at the surface of the liver (surface HCC). The aim of this study was to compare the outcome of laparoscopic hepatic resection (LH) and P-RFA for surface HCC in case-control(More)
Several noninvasive tests have been proposed to predict cirrhosis in patients with chronic hepatitis C, but not in patients with non-alcoholic steatohepatitis (NASH). We assessed whether noninvasive laboratory tests designed to predict the risk of cirrhosis in patients with chronic hepatitis C virus (HCV) infection could be used in patients with NASH. The(More)
Cytoglobin (CYGB) is ubiquitously expressed in the cytoplasm of fibroblastic cells in many organs, including hepatic stellate cells. As yet, there is no specific marker with which to distinguish stellate cells from myofibroblasts in the human liver. To investigate whether CYGB can be utilized to distinguish hepatic stellate cells from myofibroblasts in(More)
BACKGROUND/AIMS Inflammatory pseudotumor of the liver is rare, and patients with inflammatory pseudotumor frequently undergo unnecessary surgical resection as a result of misdiagnosis of malignancy. In this study, we therefore investigated inflammatory pseudotumor clinicopathologically to clarify its characteristics. METHODOLOGY Twenty patients including(More)
AIM   The usefulness of transient elastography remains to be validated in chronic hepatitis B, particularly as a tool for monitoring the degree of liver fibrosis during treatment. METHODS   The subjects were 50 patients with chronic hepatitis B virus infection. Liver biopsy was performed in 38 patients, and in 12 patients with platelet counts of 50 ×(More)
AIM The association between sarcopenia and nutritional status is thought to be an important problem in patients with cirrhosis. In this study, we investigated whether nutritional factors were related to sarcopenia in patients with liver cirrhosis. METHODS The subjects were 50 patients with cirrhosis aged 41 years or older. In this study, the subjects were(More)
Gastroparesis, a gastrointestinal autonomic neuropathy, is a common adverse reaction in chronic hepatitis C (CHC) patients receiving interferon therapy. Current therapeutic options are limited. We evaluated the efficacy of mosapride for IFN-induced gastroparesis. Twenty-four consecutive CHC patients were randomly assigned to either the control group, which(More)
Hepatocellular carcinoma (HCC) develops several years after the eradication of hepatitis C virus (HCV) by interferon therapy. Risk factors for the development of HCC are only partly understood. To elucidate the role of occult hepatitis B virus (HBV) infection in hepatocarcinogenesis in patients with sustained virologic response, the prevalences of(More)
