This study aimed to test the role of hydrogen sulfide (H2S) in responses regarding nitric oxide- (NO) and sulfur (S)-mediated improvement photosynthesis growth under cadmium (Cd) stress mustard (Brassica juncea L. cv. Giriraj), integrate mechanisms S, nitrogen (N), antioxidant metabolism. The plants grown with Cd (200 mg kg−1 soil) exhibited reduced assimilation S N diminished photosynthetic pe...

Persons afflicted with protein malnutrition are generally deficient in a variety of essential micronutrients like zinc, copper, iron, and selenium, which in turn affects number of metabolic processes in the body. To evaluate the protective effects of zinc on the enzymes involved in oxidative stress induced in liver of protein-deficient rats, the current study was designed. Zinc sulfate at a dos...

BACKGROUND Oxidative stress, as measured by 8-iso-prostaglandin F(2)(alpha) (8-iso-PGF(2)(alpha)), and depleted antioxidant defenses were shown in stable cystic fibrosis (CF) patients. The plasma fatty acid status of CF patients was linked to oxidative stress after respiratory exacerbations. OBJECTIVE We examined changes in plasma 8-iso-PGF(2)(alpha), antioxidant defenses, plasma fatty acid s...

We studied the effects of mexidol (3-oxy-6-methyl-2-ethylpiridine succinate) on antioxidant glutathione system in rat brain mitochondria experimental Parkinson’s disease induced by rotenone administration. Wistar rats were divided into following groups 6 each: I - intact (control); II (3 mg/kg per day) was injected subcutaneously for 2 weeks; III after intoxication, (50 intraperitoneally weeks....

Using prebiotics as functional ingredients in aquafeed is an emerging approach to prevent disease and improve fish production. This study explored the effect of supplementing with selenium-enriched prebiotic on growth performance, plasma lysozyme activity, oxidative enzymes activities various tissues rainbow trout, Oncorhynchus mykiss. The scale intestinal microbiomes were also characterized. A...

Blood glutathione peroxidase (GSH-Px) levels in 709 normal dromedary camels (442 females and 267 males) were assessed in the Canary Islands. All animals were intensively reared, and three different nutritional systems were evaluated, depending on selenium content of the diet. Mean GSH-Px level in the total population was 288.5+/-157.2 IU x g(-1) Hb. Reference ranges were estimated and enzymatic...

Objectives: Alteration in lipid profiles and increased levels of oxidative stress have been implicated in the cardiotoxicity induced by arsenic. Selenium and vitamin E against metal-induced cytotoxicity have been showed protective effects and well documented. However, the effectiveness of them to reduce arsenic-induced cardiotoxicity in has not yet been evaluated. So, the present work was under...

Antioxidant properties of ghrelin have been recently reported on various oxidative stresses in limited tissues. This study was set to examine the possible antioxidative effects of ghrelin in rat ovarian tissue. Twenty eight female adult Wistar rats were randomly allocated into control and treatment groups. Treatment group (n=14) received 2nmol of ghrelin as subcutaneous injection for 14 consecu...

BACKGROUND High dietary intake of selenium or soybean isoflavones reduces prostate cancer risk. These components each affect androgen-regulated gene expression. The objective of this work was to determine the combined effects of selenium and isoflavones on androgen-regulated gene expression in rat prostate. METHODS Male Noble rats were exposed from conception until 200 days of age to diets co...
