Non-alcoholic fatty liver disease (NAFLD) is a dominant cause of chronic liver disease, but the exact mechanism of progression from simple steatosis to nonalcoholic steatohepatitis (NASH) remains unknown. Here, we investigated the role of exosomes in NAFLD progression. Exosomes were isolated from a human hepatoma cell line treated with palmitic acid (PA) and their miRNA profiles examined by microarray. The human hepatic stellate cell (HSC) line (LX-2) was then treated with exosome isolated from

Chronic ethanol consumption can cause sustained hepatocellular injury and inhibit the subsequent regenerative response. These effects of ethanol may be mediated by impaired hepatocyte survival mechanisms. The present study examines the effects of ethanol on survival signaling in the intact liver. Adult Long Evans rats were maintained on ethanol-containing or isocaloric control liquid diets for 8 weeks, after which the livers were harvested to measure mRNA levels, protein expression, and kinase o

BACKGROUND: Although the pathogenesis of non-alcoholic fatty liver disease (NAFLD) remains poorly understood, metabolic syndrome associated with insulin resistance is the most reproducible factor in the development of NAFLD. Fat accumulation in hepatocytes results from an imbalance in the input, output and oxidation of fatty acid. Peroxisomes contain a battery of fatty acid oxidizing enzymes, the first of which, acyl-CoA oxidase (AOX), initiates the beta-oxidation spiral. One of the mammalian pe

Breast cancer is the most common cancer among women worldwide, and it is a main cause of death in women. As with breast cancer, metabolic components are important risk factors for the development of nonalcoholic fatty liver disease (NAFLD). In this retrospective cohort study, we aimed to determine the prevalence of NAFLD in patients with breast cancer and the impact of NAFLD on the prognosis of breast cancer.Patients with breast cancer were enrolled in the study from January 2007 to June 2017. H

Terlipressin-induced hyponatremia occurred frequently, especially in young patients with good liver function and higher Na level. Caution is required when administering terlipressin to patients with low body mass index.

INTRODUCTION: Because nonalcoholic fatty liver disease (NAFLD) is becoming a leading cause of chronic liver disease, noninvasive evaluations of its severity are immediately needed. This prospective cross-sectional study evaluated the effectiveness of noninvasive assessments of hepatic steatosis, fibrosis, and steatohepatitis. METHODS: Patients underwent laboratory tests, liver biopsy, transient elastography, and MRI. Multiparametric MR was used to measure MRI proton density fat fraction, MR spec

The paradigm for the treatment of chronic hepatitis C (CHC) has been changed due to the development of direct acting antivirals (DAAs) of hepatitis C virus (HCV). The high sustained virologic response rate and ease of administration makes the DAAs approach ideal to contribute to the complete eradication of HCV. Currently, treatment options for individual patients vary depending on the genotype or subtype of HCV, presence or absence of liver cirrhosis, previous experience of antiviral treatment o

Potent antiviral agents effectively reduce liver-related events in patients with chronic hepatitis B. This study aimed to determine whether alanine aminotransferase normalization using potent antiviral agents was related to hepatocellular carcinoma development. From 2007 to 2017, we included 610 patients with chronic hepatitis B who received entecavir or tenofovir disoproxil fumarate. The patients were divided into the alanine aminotransferase normalization group (Gr.1) and non-normalization gro

BACKGROUND AND AIMS: Although both corticosteroids and pentoxifylline are currently recommended drugs for the treatment of patients with severe alcoholic hepatitis, their effectiveness in reducing mortality remains unclear. In this systematic review, we aimed to evaluate the therapeutic and adverse effects of corticosteroids, pentoxifylline, and combination by using Cochrane methodology and therefore determine optimal treatment for severe alcoholic hepatitis. METHODS: We searched MEDLINE, EMBASE

Noninvasive techniques for evaluating the severity of nonalcoholic fatty liver disease (NAFLD) have shown limited diagnostic performance. MicroRNAs (miRNAs) are useful biomarkers for diagnosing and monitoring the progression and treatment response to several diseases. Here, we evaluated whether serum exosomal miRNAs could be used for the diagnosis and prognosis of NAFLD severity. Exosomal miRNAs were isolated from the sera of 41 patients with NAFLD (diagnosed using liver biopsy) for microarray p

A genotypic shift of the HAV was identified in Korean AHA subjects, and genotype IIIA HAV has become endemic. Although there were significant differences in the biochemical responses of AHA between genotype IA and genotype IIIA patients, we did not detect any differences in clinical outcomes such as complications or mortality.

Early detection of antiviral resistant mutants is of clinical importance in patients receiving antiviral treatment. The ideal assay is sensitive, specific, accurate, reproducible and easy to perform, attains a high throughput and is able to detect mixed and novel mutations. Advantages and disadvantages of sequencing, line probe assay, DNA chip technology, peptide nucleic acid cramping, fluorescent biprobe hybridization and a new technique based on matrix-assisted laser desorption/ionization time

Clevudine shows high rates of virologic and biochemical responses in patients with chronic hepatitis B. However, the efficacy and safety of clevudine in patients with cirrhosis are unknown. The aims of this study were to evaluate the safety and to assess the virologic and the biochemical responses to clevudine in patients with cirrhosis with chronic hepatitis B virus (HBV) infection. We reviewed data from treatment-naïve patients with chronic hepatitis B with and without cirrhosis who started cl
