We examined the effects of red potato flakes (RPF) on serum antioxidant potential and hepatic mRNA in rats. The serum thiobarbituric acid-reactive substances concentration and hepatic superoxide dismutase mRNA level in rats fed RPF were significantly lower and higher respectively than those in control rats. These results suggest that RPF might improve the antioxidant system by enhancing hepatic...

Potentially damaging species (reactive oxygen, nitrogen and chlorine species) arise as by-products of metabolism and as physiological mediators and signalling molecules. Levels of these species are controlled by the antioxidant defence system. Several components of this system are micronutrients (e.g. vitamins C and E) or are dependent upon dietary micronutrients (e.g. CuZn and Mn superoxide di...

Abstract Pesticides are agrochemical used to increase agronomic production and higher economic profit. However, these chemical pesticides could be persistent in soil and water, collective in silt or bio-aggregates in biota relying upon their dissolvability, prompting various kinds of natural contamination. These pesticides have also shown detrimental effects such as phytotoxicity, genotox...

Few studies are focused on the antioxidant status and its changes in anorexia nervosa (AN). Based on the hypothesis that renutrition improves that status, the aim was to determine the plasma antioxidant status and the antioxidant enzymes activity at the beginning of a personalized nutritional program (T0) and after recovering normal body mass index (BMI) (T1). The relationship between changes i...

Spirulina maxima, which is used as a food additive, is a microalga rich in protein and other essential nutrients. Spirulina contains phenolic acids, tocopherols and beta-carotene which are known to exhibit antioxidant properties. The aim of the present study was to evaluate the antioxidant capacity of a Spirulina extract. The antioxidant activity of a methanolic extract of Spirulina was determi...

Milk contains plenty of enzymatic and non-enzymatic antioxidant components that probably account for the vital antioxidant protection of the infants at early stages of life against the development of complications induced by oxygen free radicals. Indigenous milk enzymes play a key role in regulating lactogenesis, including active involution of mammary gland. Moreover, they are essential constit...
