Objectives. To develop a new method for determining total antioxidants in serum and to evaluate the total antioxidant capacity of organisms. Design and Methods. Sodium hyposulfite (Na2S2O3) and serum were used to evaluate the linearity and precision of the potassium permanganate agar method. The area of serum diffusion in samples from 30 intensive care unit (ICU) patients compared with 44 healt...

Background: Vitiligo is an acquired, idiopathic disorder characterized by milky white patches devoid of identifiable melanocytes. Despite much research, the precise etiology of vitiligo is not clear, but it has become quite clear in recent years that complex genetic, neural, immunological and autocytotoxic mechanisms play a role in its pathogenesis. In recent studies, a defective antioxidant de...

Ethanolic extract of leaves of Elaeocarpus ganitrus was analyzed for their total antioxidant capacity, reducing power, metal chelating, ABTS+ (2, 2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) radical scavenging and hydroxyl radical scavenging activities. The extract at 500 ?g/ml showed maximum Iron chelating activity (76.70%) followed by the scavenging of the ABTS+ radical (55.77%) at the sa...

The manipulation of egg content is one of the few ways by which female birds can alter offspring quality before hatch. Lipid-soluble vitamins and carotenoids are potent antioxidants. Female birds deposit these antioxidants into eggs in variable amounts according to environmental and social conditions, and the quantities deposited into eggs can have effects on offspring health and immunological ...

Oxidative damage has been proposed as one of the possible mechanism involved in the nephrotic syndrome. Strengthening the defense system by antioxidants may provide protection against oxidative damage. Therefore, this study was carried out to investigate oxidant and antioxidant status with copper, zinc and homocysteine in nephrotic syndrome patients and the effect of antioxidants, minerals and ...

Melatonin and gamma-aminobutyric acid (GABA) have been shown to regulate sleep. The nocturnal concentrations of melatonin, GABA and total antioxidants may relate to insomnia in stroke patients. In this prospective single-center non-randomized controlled clinical trial performed in the China Rehabilitation Research Center, we analyzed the relationship of nocturnal concentrations of melatonin, GA...

Micronutrients support immune functions and are essential for optimized health production of animals. This study was conducted to evaluate the effect vitamin E C, alone or in combinations, on growth antioxidant capacity neonate dairy calves. For this purpose, eighteen female Holstein Friesian calves were selected. Experimental treatments were; T0 control (milk without supplementation), T1 suppl...
