BACKGROUND & AIMS Non-alcoholic fatty liver disease (NAFLD) is believed to be a type of metabolic syndrome. MicroRNA-122 (miR-122) is the most abundant microRNA in the liver and is an important factor for the metabolism of glucose and lipids. In the present study, we examined the correlation between the hepatic and serum miR-122 expression levels and the(More)
BACKGROUND Several clinical studies have suggested a possible link between chronic hepatitis caused by hepatitis C virus (HCV) and the development of diabetes mellitus. We investigated the association between liver fibrosis and glucose intolerance in HCV-infected patients by measuring insulin sensitivity and beta-cell function. METHOD A total of 83(More)
Although there is no definitive evidence that hepatocellular carcinoma (HCC) screening in high-risk groups improves survival, many physicians screen high-risk populations with various tools such as alpha-fetoprotein (AFP) and ultrasonography (USG). The aim of this study was to clarify clinical differences between HCC patients diagnosed by surveillance and(More)
The number and ratio of both HBsAg- and HCV Ab-negative hepatocellular carcinoma (HCC-nonBC) cases have been steadily increasing in Japan. The aim of this study was to examine the frequency of detection of HCC-nonBC by screening methods and to elucidate the clinical characteristics of HCC-nonBC compared with those of hepatitis C and/or B virus-associated(More)
Noninvasive risk factors are required for predicting the development of hepatocellular carcinoma (HCC) not only in patients with cirrhosis but also in those with chronic hepatitis who are infected with hepatitis C virus (HCV). A total of 707 patients with chronic HCV infection without other risks were evaluated for the predictive value of noninvasive risk(More)
BACKGROUND To improve the diagnostic accuracy for hepatic tumors on the liver surface, we investigated the usefulness of an indocyanine green-photodynamic eye (ICG-PDE) system by comparison with Sonazoid intraoperative ultrasonography (IOUS) in 117 patients. Hepatic segmentation by ICG-PDE was also evaluated. METHODS ICG was administered preoperatively(More)
Impaired glucose tolerance influences the prognosis of hepatocellular carcinoma (HCC), but this mechanism is still not fully understood. We investigated the impact of the fasting serum levels of insulin and adiponectin on the prognosis of HCC and its recurrence. One hundred and forty patients with newly diagnosed HCC were enrolled in the prognosis study.(More)
Several reports have indicated that nuclear factor-kappaB (NF-kappaB) is constitutively activated in a variety of cancer cells including hepatoma cells and plays a key role in their growth and survival. Dehydroxymethylepoxyquinomicin (DHMEQ) derived from the structure of an antibiotic epoxyquinomicin C is a novel NF-kappaB inhibitor. In the present study,(More)
BACKGROUND AND AIM Acute exacerbation of chronic hepatitis B has to be distinguished from acute hepatitis, because treatment strategies differ between them. METHODS Mutations in the core promoter and precore region of hepatitis B virus (HBV) were determined in 36 patients with acute exacerbation of chronic hepatitis B, in whom alanine aminotransferase(More)
BACKGROUND AND OBJECTIVES To improve diagnostic accuracy of intraoperative ultrasonography (IOUS), we investigated the usefulness of new contrast medium of microbubble agent, Sonazoid as a preliminary study. METHOD We examined IOUS in 50 patients with liver tumors who underwent hepatectomy. Sonazoid was administrated intravenously and Kupffer-phase images(More)
