Anti-apoptotic activity of human matrix metalloproteinase-2 attenuates diabetes mellitus.

Background: Chronic progression of diabetes is associated with decreased pancreatic islet mass due to apoptosis of β-cells. Patients with diabetes have increased circulating matrix metalloproteinase-2 (MMP2); however, the physiological significance has remained elusive. This study tested the hypothesis that MMP2 inhibits cell apoptosis, including islet β-cells.

Low dose of alcohol attenuates pro-atherosclerotic activity of thrombin.

Background And Aims: Thrombin, the active enzyme of the coagulation system, plays a critical role in the pathogenesis of atherosclerosis. Vascular repair promoted by stromal cell-derived factor-1 is a protective process in atherosclerosis. Consumption of low amount of alcohol is believed to reduce the risk of atherosclerotic cardiovascular disease but the mechanism is unclear.

The Associations between Circulating Bile Acids and the Muscle Volume in Patients with Non-alcoholic Fatty Liver Disease (NAFLD).

Objective Non-alcoholic fatty liver disease (NAFLD) is frequently associated with obesity, dyslipidemia and type-2 diabetes mellitus. Bile acids (BAs) bind to the farnesoid X receptor (FXR) and G protein-coupled receptor 5 (TGR5), which are involved in lipid and glucose metabolism and energy expenditure. The present study aimed to determine associations between the circulating BAs and the skeletal muscle volume (SMV), and lipid and glucose metabolism in patients with NAFLD.

Factors contributing to the development of overt encephalopathy in liver cirrhosis patients.

The aim of this study was to clarify the relationships among psychometric testing results, blood ammonia (NH3) levels, electrolyte abnormalities, and degree of inflammation, and their associations with the development of overt hepatic encephalopathy (HE) in liver cirrhosis (LC) patients. The relationships between covert HE and blood NH3, sodium (Na), and C-reactive protein (CRP) were examined in 40 LC patients. The effects of elevated NH3, hyponatremia, and elevated CRP on the development of overt HE were also investigated.
