We used an RIA and inhibition of enzyme activity to monitor the changes in mass and catalytic concentrations of the aspartate aminotransferase (EC 2.6.1.1;AST) isoenzymes in serum after myocardial infarction. Cytosolic (c-AST) and mitochondrial (m-AST) forms of AST were present in sera from all 38 of our patients. Although the immunological and catalytic concentrations of both isoenzymes correl...
PURPOSE Endothelial dysfunction (ED) is a pivotal phenomenon in the development of cardiovascular disease (CVD) in patients receiving hemodialysis (HD). Indoxyl sulfate (IS) is a known uremic toxin that induces ED in patients with chronic kidney disease. The aim of this study was to investigate whether AST-120, an absorbent of IS, improves microvascular or macrovascular ED in HD patients. MAT...
Various serum biomarkers have been developed for predicting head and neck squamous cell carcinoma (HNSCC) prognosis. However, none of them have been proven to be clinically significant. A recent study reported that the ratio of aspartate aminotransaminase (AST) to alanine aminotransaminase (ALT) had a prognostic effect on non-metastatic cancers. This study aimed to examine the effect of the AST...
BACKGROUND Our ongoing research has revealed that total saponins extracted from the medicinal herb Radix Astragali (AST) exhibits significant growth-inhibitory and proapoptotic effects in human cancer cells. In the present study, the potential of AST in controlling angiogenesis was further investigated with elaboration of the underlying molecular mechanism in human colon cancer cell and tumor x...
CONTEXT Paracetamol (acetaminophen or APAP) is the most common pharmaceutical exposure in the US. Elevations in aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels indicate hepatic toxicity. AST and ALT levels rise in similar proportions but later decline at different rates, with AST falling more rapidly than ALT. OBJECTIVE To determine whether the AST/ALT ratio can ind...
background: hepatic steatosis due to estrogen therapyincreases the activity of inflammatory markers, particularly theactivity of tnfα which in turn induces more lipogenesis.omega-3 fatty acids are among the negative regulators of hepaticlipogenesis. objectives: in this research, the preventive effectof omega-3 fatty acids on estrogen-induced steatosis in rats wasevaluated. methods:2 mg/kg. bw/s...
Neuropeptides of the cockroach allatostatin (AST) family are known for their ability to inhibit the production of juvenile hormone by the corpora allata of cockroaches. Since their discovery, they have also been shown to modulate myotropic activity in a range of insect species as well as to act as neurotransmitters in Crustaceans and possibly in insects. The midgut of cockroaches contains numer...
