Since little is known about the effect of selenium on the fatty acid profiles (FAP) of human breast milk, the purpose of this study was to measure the effect of habitual dietary selenium (Se) intake on this profile in plasma and breast milk. Subjects were lactating women from three locations in China where habitual selenium intakes are extremely low (Xichang), adequate (Beijing), or extremely h...

A pot culture experiment was carried out to assess the effect of sulfur stress on growth, oxidative status, and antioxidative metabolism. Onion plants were treated with three different levels of sulfur, namely, 1.0, 4.0, and 8.0 mM S L(-1). Plants raised with 4.0 mM S L(-1) represent sufficient growth for the best vegetative yield. Plants supplied with 1.0 and 8.0 mM S L(-1) showed retarded gro...

The aim of the study was to determine the effect of a 5 min head-out ice-cold water bath on the oxidant-antioxidant balance in response to exercise. The crossover study included the subjects (n = 24; aged 28.7 ± 7.3 years) who performed two identical stationary cycling bouts for 30 min and recovered for 10 min at room temperature (RT = 20°C; session 1) or in a pool with ice-cold water (ICW = 3°...

Effects of Pongamia pinnata, an indigenous plant used in Ayurvedic Medicine in India on the temporal variations of circulatory lipid peroxidation products and antioxidants in ammonium chloride-(AC)-induced hyperammonemic rats has been studied. Experimental rats were divided into control, AC-treated, those treated with AC + ethanolic leaf extract of P. pinnata (PPEt), and PPEt-treated. The...

background:  the development of nanotechnology has been a boon to mankind as its significance paved the way for several applications in therapeutics. this study was to evaluate the anti-arthritic capability of nano selenium-lovastatin mixture (lov-se) against inflammatory cascade in arthritic irradiated rats. materials and methods: animal model of arthritis was organized by subcutaneous injecti...

Several decades after the discovery of selenium as an essential trace element in vertebrates approximately 20 eukaryotic and more than 15 prokaryotic selenoproteins containing the 21st proteinogenic amino acid, selenocysteine, have been identified, partially characterized or cloned from several species. Many of these proteins are involved in redox reactions with selenocysteine acting as an esse...

The goal of the experiment was to compare the effect of supplementation of inorganic and the new organically bound (lactate-protein selenium complex) form of selenium (Se) in feed for goats. The 31 goats were split into three groups: control (C) without Se supplementation, AN group administered sodium selenite, ORG group administered lactate-protein selenium complex (Selene Chelate, Agrobac, Cz...

Liver function tests, thyroxin and triiodothyronine levels, and hepatic 5’deiodinase and glutathione peroxidase enzyme activities were measured. Triiodothyronine levels in the carbon tetrachloride group and carbon tetrachloride + selenium group were significantly lower than in the control group (P<0.01, P<0.05, respectively). In the carbon tetrachloride + selenium group, the level of triiodothy...

Oxidative stress has been implicated in pesticide-induced neurotoxicity, based on its role in the cascade of biochemical changes that lead to dopaminergic neuronal cell death. We have, therefore, examined the role of oxidative stress caused by the pesticides endosulfan and zineb in human neuroblastoma cells (SH-SY5Y) in culture. Upon treatment with 50-200 μM concentrations of either of these pe...

This report describes a four-day-old, full-term Connemara colt, presented for the evaluation of a progressive inability to rise unassisted. A diagnosis of nutritional muscular dystrophy was made based on muscular weakness, elevated muscle enzymes and low vitamin E, selenium and glutathione peroxidase activity. The foal was treated with intramuscular vitamin E-selenium and made a full recovery.
