BACKGROUND The formation of free radicals in human skin by solar ultraviolet radiation is considered to be the main reason for extrinsic skin aging. The antioxidants in human tissue represent an efficient protection system against the destructive action of these reactive free radicals. In this study, the parameters of the skin, epidermal thickness, stratum corneum moisture, elasticity and wrink...

the objective of this study was to produce fish protein hydrolysate (fph) with the most antioxidant activity, by enzymatic hydrolysis from (carassius carassius). the protein of crucian carp a low value fish was hydrolyzed by alcalase 2.4l and the optimal hydrolysis parameters of strongest antioxidant capacity of peptides were obtained using response surface methodology (rsm) by the central rota...

BACKGROUND Orthodox Christian believers fast abstaining from meat, eggs, dairy products or even fish and oil in certain days of the fasting period, three times a year. AIM The present study aimed to investigate the impact of a 48-day fast before Easter in blood count parameters, coagulation and antioxidant status. MATERIAL AND METHODS A total of 35 healthy volunteers, 19-66 years old, were ...

Possible anticancer mechanisms exerted by polyphenolic compounds contained in fruits and vegetables include antioxidant activity, the inhibition of proliferation, and the induction of apoptosis in cancer cells. This study examined the effects of four isolated polyphenolic extracts from red muscadine grapes (Vitis rotundifolia) on vital cell parameters and the induction of apoptosis in Caco-2 co...

Moringa oleifera Lam. (Moringaceae) is highly valued plant reported to have various biological activities. Considering the antioxidant properties of Moringa oleifera (MO), the chemopreventive property of hydro-ethanolic extract of drumsticks was evaluated on DMBA induced renal carcinogenicity. Groups of 10 male mice were preadministered with MO (200 and 400mg/kg body weight) and standard (0.5%B...

In this paper it is studied the ways by which the radical cation chromophore of chlorpromazine, produced through a reaction between chlorpromazine maleate and potassium persulfate in hydrochloric acid medium, can be applied in realization an evaluation method of the antioxidant activity. The chlorpromazine radical cation is a radical with biological relevance, being involved in oxidative proces...

this study was conducted to evaluate the burn wound healing and antioxidant activity of methanolic and aqueous extracts of galium odoratum (l.) scop. in rats. second degree burn wounds were induced in six groups of six rats each. groups 1 and 2 received eucerin and silver sulfadiazine as control and reference standard and groups 3, 4, 5 and 6 were given methanolic and aqueous extracts of 15% an...

The present investigation was executed with an objective to study the effects of Co stress in Arachis hypogaea L. with special emphasis on antioxidant enzymes activities which are the defense mechanism to any type of abiotic stress. In this we have analysed the effect of cobalt (Co) stress on antioxidant enzyme activities (catalase, peroxidase and polyphenol oxidase) of Arachis hypogaea L. were...

The various risk factors for peripheral arterial disease (PAD) are almost identical to those for atherosclerosis and include abnormal levels of lipids or lipoproteins. Lipid peroxidation parameters and total antioxidant capacity in the serum of male patients with PAD before surgery as well as 3-5 days and 7-10 days after surgery were measured. We also compared these parameters with those in a g...

Background and Objective: Acrylamide is a highly soluble, widely- produced industrial and cytotoxic material. Some substances with antioxidant properties can ameliorate the deleterious effect of acrylamide. Vitamin C is necessary for the normal functioning of all cells and scavenging the free radicals due to the antioxidant properties. The present study was aimed to evaluate the effect of vitam...
