Cardiovascular disease is the major cause of mortality in patients receiving hemodialysis for chronic renal failure. Increased lipid peroxidation and depletion of chain-breaking antioxidants may contribute to increased risk of atherosclerosis. We have therefore assessed the effect of a single episode of hemodialysis on antioxidant status in 22 patients and control subjects. Overall, total antio...
We aimed to investigate markers of oxidative stress and levels of endogenous and dietary antioxidants in 16 elite female soccer players in response to a 90-min game (average intensity 82+/-3% HRpeak). Blood samples were taken before, immediately and 21 h after the game. Plasma-oxidized glutathione, the ratio of reduced to oxidized glutathione (GSH:GSSG) and lipid peroxidation measured by d-ROMs...
Blackberry processing generates up to 20% of residues composed mainly of peel, seeds and pulp that are abundant in flavonoids. The objective of this study was to optimize the ultrasound conditions, in a closed system, for antioxidants extraction, using the response surface methodology. Blackberry (Rubus fructicosus) residues were analyzed for total phenolics, total anthocyanins, and antioxidant...
Fruit from three genotypes (‘B-76’, ‘B-59’ and ‘SHF-3A’) of deerberry [Vaccinium stamineum L.] were evaluated for fruit quality, total anthocyanin and phenolic contents, antioxidants, antioxidant capacity, and antioxidant enzyme activity. The fruit soluble solids, titratable acids, total anthocyanins, and total phenolic contents varied with genotypes. Cyanidin 3-galactoside and cyanidin 3-arabi...
Drought is an important environmental constraint limiting the productivity of many crops worldwide. Experiments were conducted to investigate the effects of foliar spray of natural extract (garlic extract) on drought stress in two cultivars of soybean (Glycine max) plants. Drought stress caused significant decrease in growth parameters (shoot and root length, area of leaves, fresh and dry weigh...
The aim of this study was to evaluate the influence triplicate blend natural antioxidants on sensorial, physicochemical and microbiological characteristics cooked sausage. Three antioxidants: sodium L-ascorbate (x1), dihydroquercetin isolate from Larix sibirica Ledeb (x2) lyophilized ethanol (30%) extract dry distilled rose ( Rosa damascena Mill) petals (x3) were studied in doses 0, 0.05 0.1 g/...
In samples of different tea brands the content biologically active substances (total water-soluble antioxidants content, ascorbic acid, rutin, polyphenols, anthocyanins) was determined. The antioxidant biological availability studied evaluated. Green Tea with Lemon and Ceylon Baikhovi Black Spiced is characterized by similar levels bioavailability. After consumption both beverages, there a defi...
Background: Blood lipids can influence fat-soluble antioxidant concentrations and confound their interpretation as indicators of antioxidant intake status and disease risk. Objectives: The objectives were to identify lipoproteins that can confound the interpretation of serum fat-soluble antioxidants, to evaluate the amount of the confounding, and to recommend a method for standardizing blood co...
