A Review of Laboratory Methods for Measuring Oxidative Stress
Introduction: Antioxidant defense system, including enzymatic and non-enzymatic antioxidants, protects cells from oxidative damage by neutralizing oxidant compounds. Increasing the production of oxidant species and decrease activity of antioxidant system causes oxidative stress. The role of oxidative stress in the pathogenesis of human diseases and strengthening of human antioxidant defense sys...
متن کاملThe ADMA-Metformin Hypothesis: Linking the Cardiovascular Consequences of the Metabolic Syndrome and Type 2 Diabetes.
Metformin and asymmetric dimethylarginine (ADMA) are structural analogs. They have opposite effects at multiple points on complex signaling pathways that coordinate energy, molecular synthesis, growth, and metabolism with nutrient intake. Excess saturated fats and glucose may initiate the methylation of arginine residues in proteins involved in the transcription of genes mediating inflammation,...
متن کاملAsymmetric dimethylarginine and kidney disease--marker or mediator?
A symmetric dimethylarginine (ADMA) is a naturally occurring amino acid that circulates in blood and is excreted in urine (1). It is also a competitive inhibitor of all three isoforms of nitric oxide synthase (NOS). ADMA competes with arginine for the binding site of NOS with an IC50 of about 10 M depending on the prevailing concentration of arginine (2). Combine these observations and it is po...
متن کاملImpact of Indoxyl Sulfate, a Uremic Toxin, on Non-Culprit Coronary Plaque Composition Assessed on Integrated Backscatter Intravascular Ultrasound.
BACKGROUND Uremic toxin has emerged as an important determinant of cardiovascular risk. The aim of this study was to examine the relationship between serum uremic toxin and coronary plaque composition on integrated backscatter intravascular ultrasound (IB-IVUS). METHODS AND RESULTS IB-IVUS was performed in 47 patients with planned treatment for angina pectoris. Non-culprit intermediate plaque...
متن کاملAsymmetrical dimethylarginine: the Uber marker?
The traditional risk factors of hypercholesterolemia, hypertension, diabetes mellitus, and tobacco exposure identify a subset of patients at greater cardiovascular risk. A variety of clinical phenotypes, biochemical markers, and genetic polymorphisms have been proposed to explain the variance in risk not explained by the traditional factors. Notably, all of the traditional risk factors, as well...
