Determination of the relative contribution of uric acid level increases to the total measured antioxidative activity could be very useful for testing antioxidative products and their effect on human health. The aim of this report is to present a simple spectrophotometric method that combines the measurement of total antioxidative capacity of a sample by ferric reducing/antioxidative power (FRAP...

The aim of this review is to study the main spectrophotometric methods used to evaluate total antioxidant capacity (TAC) in serum samples of dogs. Total antioxidant capacity (TAC) is an analyte frequently used to assess the antioxidant status of biological samples and can evaluate the antioxidant response against the free radicals produced in a given disease. Trolox equivalent antioxidant capac...

background: cryopreservation of pre-antral follicles is a hopeful technique to preserve female fertility. the aim of the present study was to evaluate reactive oxygen species (ros) and total antioxidant capacity (tac) levels of mouse vitrified pre-antral follicles in the presence of alpha lipoic acid (ala). methods: isolated pre-antral follicles (140–150 µm in diameter) were divided into vitrif...

inflammation and pain induced by delayed onset muscle soreness (doms) can be induced by eccentric exercise or an unaccustomed activity. the condition can causes problems in exercising and for athletes. the purpose of this study was to assess the effect of 150mg curcumin supplementation immediately after intensive eccentric exercise. evaluations were made for total antioxidant capacity (tac), mu...

background: brucella species can cause infection in a wide range of animals and human beings. oxidative events against brucella infection are not well elucidated. it is possible that brucellosis may be related to increased free radical production and antioxidant depletion. thus, the aim of this study was to determine the total antioxidant capacity (tac) before and after treatment of patients wi...

The objective of this article was to review the effects of xenobiotics on total antioxidant capacity (TAC). Measurement of TAC is appropriate for evaluation of the total antioxidant defenses of blood, cells, and different kinds of tissues and organs. TAC is reduced by alcoholism, smoking, and exposure to radiation, herbicides, carbon monoxide, carbon tetrachloride, lead, arsenic, mercury, cadmi...

BACKGROUND: Antioxidant molecules, which scavenge free radical species to prevent or delay oxidative damage of important macromolecules, membrane lipids and lipoproteins, are prevalent in plasma and other biological fluids. Among them, bilirubin, uric acid and protein thiols are the major endogenous antioxidants, while vitamins C and E, as well as a number of food-derived (poly)aromatic substan...
