BACKGROUND There are no previous studies investigating the effect of all dietary antioxidants in relation to myocardial infarction. The total antioxidant capacity of diet takes into account all antioxidants and synergistic effects between them. The aim of this study was to examine how total antioxidant capacity of diet and antioxidant-containing foods were associated with incident myocardial in...

It would be desirable to establish and standardize methods that can measure the total antioxidant capacity level directly from vegetable extracts containing phenolics. Antioxidant capacity assays may be broadly classified as electron transfer (ET)- and hydrogen atom transfer (HAT)-based assays. The majority of HAT assays are kinetics-based, and involve a competitive reaction scheme in which ant...

The green synthesis of metallic nanoparticles is an active research area in nanotechnology. In the present study, antioxidant potential, total reducing capacity and silver nanoparticles' (Ag NPs) synthetic potential of methanolic leaf extracts of seven plant species were evaluated and compared. Antioxidant capacity, expressed as µmol Trolox equivalents g-1 DW (µmol TE g-1 DW), ranged from 116.0...

background: fat-rich diet may alter oocyte development and maturation and embryonic development by inducing oxidative stress (os) in follicular environment. objective: to investigate the relationship between fat intake and oxidative stress with oocyte competence and embryo quality. materials and methods: in observational study follicular fluid was collected from 236 women undergoing assisted re...

background: a high percentage of patients admitted to the intensive care unit (icu) have systemic inflammatory response syndrome (sirs) criteria. free radicals play an important role in initiation and development of sirs. the purpose of this study was to assess and compare the molecular changes of cellular antioxidant power in patients with sirs who received enteral nutrition (en) or en combine...

different contraceptive methods are used by breastfeeding mothers. in general, these methods are classified into two major groups, hormonal and non-hormonal. a number of studies have shown that combined oral contraceptive pills may adversely affect the quality and the quantity of human milk. in other studies it has been shown that estrogen and progesterone seem to reduce the risk of cardiac and...

background there is currently great concern about the possible adverse effect of microwave radiation from cell phones. in addition, noise is one of the physical pollutants of modern societies. objectives the present study aimed to examine the separate and simultaneous effects of cell phone microwaves, noise, and their effects on sperm parameters and total antioxidant capacity in adult male rats...

The aim of this investigation was to assess the influence of beers with different antioxidant potentials on plasma lipid metabolism, plasma antioxidant capacity, and bile excretion of rats fed cholesterol-containing and cholesterol-free diets. Four types of beers were investigated in vitro. Two of them (designated as BeerHigh and BeerLow) with the highest and lowest antioxidant potentials (34.5...

  Purpose: The aim of this study was to investigate the effect of four weeks supplementation of   vitamin C on serum levels of total antioxidant capacity and malondialdehyde among inactive   men after an eccentric exercise.   Materials and Methods: Twenty non-athletic healthy volunteer men (24 ± 1.6 years old,   22.59 ± 2.62 body fat percentage and 48.96 ± 3.58 mL/kg/min maximum oxygen uptake) ...
