In view of the significant role of Hsp70 in protecting the organism against the destructive effects of stress, and the possibility of using this protein as a marker of the infarction process in the heart, the aim of this study was to conduct an evaluation of the expression of 70kDa heat shock proteins (Hsp70) and the concentration of TBARS (thiobarbituric acid reactive substances) and nitric ox...

PURPOSE The aim of this work was an evaluation of the influence of physical exercise in high-altitude conditions (about 2000 m above sea level) on thiobarbituric acid reactive substances (TBARS) and superoxide dismutase (SOD) and catalase (CAT) activities in 10 kayakers and 10 rowers. METHODS During their training, the sportsmen performed different kinds of static and dynamic efforts. The blo...

The intense artificial sweetener sucralose has no bioconcentration properties, and no adverse acute toxic effects have been observed in standard ecotoxicity tests, suggesting negligible environmental risk. However, significant feeding and behavioural alterations have been reported in non-standard tests using aquatic crustaceans, indicating possible sublethal effects. We hypothesized that these ...

Chronic ethanol consumption leads to oxidative stress in the heart and erythrocytes of rats. As Ziziphus jujuba fruit has been shown to have potent antioxidants, such as flavonoids, we conducted this study to evaluate the effects of aqueous fruit extracts from Z. jujuba on rat hearts and erythrocytes following chronic ethanol consumption. Twenty-eight male Wistar rats were randomly divided into...

Background: This study examined the association between advanced glycation end-products (AGE) and serum markers of oxidative stress and inflammation in diabetic patients with or without diabetic foot ulcers. Methods: Eighty-two adult participants were recruited and assigned to one of three groups: 1) non-diabetic control; 2) diabetic participants without foot ulcers (DM); and 3) diabetic partic...

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...

This study investigates the effect of oral administration of an aqueous Enicostemma littorale whole plant extract on antioxidant defense in alloxan-induced diabetes in rats. A significant increase in blood glucose and increased concentration of thiobarbituric acid reactive substances (TBARS) and hydroperoxides (HP) in liver, kidney and pancreas were observed in alloxan diabetic rats. Decreased ...

The aim of this work was to determine if the inhibition or stimulation of NO synthesis modulates liver damage induced by chronic lead intoxication. Lead nitrate (3.6 mg/kg, per os) was administered one time a day for 30 days to male Wistar rats with low and high resistance to hypoxia treated simultaneously with L-arginine (600 mg/kg, i.p.) or N-nitro-L-arginine (L-NNA, 35 mg/kg, i.p.) 30 min. b...

The utilisation of Moringa oleifera leaves powder (MOLP) to improve the nutritional properties and inhibit lipid oxidation proliferation microorganisms in ground beef during cold storage was examined. effects 0.2, 0.4, 0.6, 0.8% MOLP on (proximate composition, total phenolic flavonoid content), thiobarbituric acid reactive substances (TBARS), microbial physicochemical characteristics (pH value,...

Abstract Metals and agrochemicals are among the main aquatic contaminants, being able to trigger oxidative stress in exposed organisms. The objective of this work was evaluate correlation between level biomarkers Aegla crabs (Crustacea, Anomura) with (i) set metals present streams sediment (ii) land uses three hydrographic basins. study carried out (≤ 2nd order) basins southern Brazil (Basins R...
