AIM To determine the comparative efficacy of oral anti-diabetic drugs in preventing the development of Type 2 diabetes. METHODS A systematic literature search of MEDLINE, EMBASE and Cochrane CENTRAL was conducted for randomized controlled trials evaluating oral anti-diabetic drugs in patients at high risk for developing Type 2 diabetes. Mixed-treatment comparison meta-analysis methods were us...

Inflammatory brain disease may damage cerebral vascular endothelium leading to cerebral blood flow dysregulation. The proinflammatory cytokine TNF-alpha causes oxidative stress and apoptosis in cerebral microvascular endothelial cells (CMVEC) from newborn pigs. We investigated contribution of major cellular sources of reactive oxygen species to endothelial inflammatory response. Nitric oxide sy...

An efficient method for examining the selectivity of inhibitors on two alpha-fucosidases, one from Thermotoga maritima and the other from human, was established. The X-ray crystal structure of the former enzyme makes possible the homology modeling of the human alpha-fucosidase, indicating the major difference between both enzymes in the periphery of the catalytic site. To investigate the differ...

INTRODUCTION The increasing prevalence of type 2 diabetes mellitus and the negative clinical outcomes observed with the commercially available anti-diabetic drugs have led to the investigation of new therapeutic approaches focused on controlling postprandrial glucose levels. The use of carbohydrate digestive enzyme inhibitors from natural resources could be a possible strategy to block dietary ...

Transglutaminase 2 (TGase 2) expression is increased in inflammatory diseases. We demonstrated previously that inhibitors of TGase 2 reduce nitric oxide (NO) generation in a lipopolysaccharide (LPS)-treated microglial cell line. However, the precise mechanism by which TGase 2 promotes inflammation remains unclear. We found that TGase 2 activates the transcriptional activator nuclear factor (NF)...

Although rheumatoid joint fluids contain numerous polymorphs capable of secreting neutral proteases known to be able to digest cartilage, the high level of inhibitors (mainly alpha 1-antitrypsin and alpha 2-macroglobulin) has always been considered to be more than sufficient to inhibit their activity completely. Consequently little interest has been paid to the potential role of these enzymes i...

The article justifies the need for a large arsenal of drugs to treat perennial rheumatoid arthritis. authors present randomized controlled trial data showing high efficacy tofacitinib at different doses as monotherapy, or in combination with methotrexate, other conventional synthetic disease-modifying anti-inflammatory suppressing activity and progression disease various groups patients, both n...

Abnormal vascular smooth muscle cell (VSMC) proliferation is a key feature of atherosclerosis and restenosis; however, the mechanisms regulating growth remain unclear. Herein we show that inhibition of the aldehyde-metabolizing enzyme aldose reductase (AR) inhibits NF-kappa B activation during restenosis of balloon-injured rat carotid arteries as well as VSMC proliferation due to tumor necrosis...
