BACKGROUND To evaluate the role of thiobarbituric acid reactive substance (TBARS) and nitric oxide (NO) as biochemical biomarkers and central subfield (CST) and cube average thickness (CAT) as biomarkers for medical imaging in diabetic retinopathy. METHODS Forty consecutive cases of diabetic retinopathy and 20 healthy controls were included. Cases were divided into two groups: non proliferati...

Glucose-6-phosphate dehydrogenase (G6PD) deficient subjects are vulnerable to oxidative stress. Quercetin, a flavonoids, has been employed as a potent oxygen-free radical scavenger in order to assess the protective effects of quercetin against H2O2-induced oxidative damage in G6PD-deficient and normal human erythrocytes. Erythrocytes of G6PD-deficient (n = 10) and normal (n = 10) subjects were ...

Cadmium (Cd) is a dangerous occupational and environmental toxin. Exceeding its permissible weekly uptake in meals is a disturbing phenomenon. The aim of this study is to assess the effect of long-term uptake of cadmium chloride on selected biochemical parameters and oxidative stress biomarkers in animal models. Long-term intoxication with cadmium chloride elevated blood serum concentration of ...

The aim of this study was to determine the effects dried peach leaves powders with different methods on pH and Thiobarbituric acid reactive substances (TBARS) values, cooking, textural sensory properties beef patties. Samples were divided into six treatment groups; control (without leaf powder/ Butylhydroxytoluene (BHT)), patties BHT (0.01%), containing (PLP) in air (AP) (%1) microwave oven (Mw...

N-Phthaloyl GABA was administrated daily (50 mg/Kg body weight-i.p) to Wistar rats for 21 days and circadian rhythms of thiobarbituric acid reactive substances (TBARS) and antioxidants such as reduced glutathione (GSH), catalase (CAT) and superoxide dismutase (SOD) were studied under constant light (LL) conditions. Delayed acrophase of TBARS and advanced acrophase of antioxidants (GSH, CAT and ...

Four commercial brands of infant milk formula were investigated, and the amount of shelf lipid peroxidation was determined by measuring malondialdehyde (MDA) or, more exactly, thiobarbituric acid reactive substance (TBARS) levels, which are the end products of lipid peroxidation. TBARS level, indicated by MDA concentration, was higher in the vegetarian brands. The vegetarian brands are, as expe...

Introduction: The aim of this study was to evaluate thiobarbituric acid reactive substances (TBARS) as lipid peroxidation marker and total antioxidant capacity(TAC) in saliva of smoker and non-smoker men. Materials & Methods: This case-control study was performed on 104 men including smoker (52) and non-smoker (52) men, referred to the Oral Medicine Department in Babol Faculty o...

Oxidative stress plays a major role in the pathogenesis of diabetic mellitus. The present study was undertaken to assess lipid peroxidation by TBARS, antioxidant status using FRAP and inflammatory status using sialic acid in patients with Type2 Diabetes mellitus and healthy individuals in rural population. AnthropometricBiochemical, Fasting insulin, HOMA-IR were estimated in both groups. We obs...
