Organic milk production has increased rapidly in many European countries during the last decade but the merits of organic dairy products are still disputed. Little unbiased information exists regarding any essential differences in gross composition or other parameters of technological and/or nutritional interest. In order to gather more basic information regarding organic milk, raw milk samples...

The purpose of this study was to compare the effect and toxicity of organic selenium (Pro-Se) with inorganic selenium (IOSe) in preventing asthma in ovalbumin-induced asthmatic mice. After the mice were treated orally with Pro-Se and IOSe, respectively, the plasma Se levels, Se accumulation in liver and kidney, tumor necrosis factor alpha (TNF- α ), interleukin 1 beta (IL-1 β ), oxidative stres...

Radioprotective agents like selenium are used to reduce the damage caused by radiation in healthy tissues. The aim of this study was to evaluate the effect of sodium selenite on the development of the molars of offspring of rats irradiated during odontogenesis. Twenty pregnant rats were randomly divided into 4 groups: control, irradiated, selenium and selenium/irradiated. The selenium and selen...

This study was conducted to determine the effects of vitamin E selenium ( Na2-SeO3) and organic selenium (Sel-Plex) on performance of broiler reared under chronic heat stress during summer season (30.043.5°C). A total of 180 one-day-old broiler chicks were randomly assigned to three selenium treatments, and two stocking density with two replicates of 15 birds each. The birds with a 3 x 2 factor...

The aim of this study was to evaluate the biological and chemical response of Allium cepa L. exposed to inorganic selenium compounds. Besides the investigation of the total content of selenium as well as its chemical speciation, the Allium test was used to evaluate the growth of onion roots and mitotic activity in the roots' meristem. The total content of selenium was determined by inductively ...

Linseed is well known for abundant content of α-linolenic acid why it has been widely used as a source of n-3 fatty acid. Higher ratio of polyunsaturated fatty acids can increase lipid peroxidation. Selenium (Se) plays a key role in antioxidant enzymes and can therefore be regarded for use in attempts focused on protection of fatty acids from oxidation. The organic Se has been shown to have hig...

To investigate whether selenium (Se) accumulation in plants provides a chemical defense against generalist insect herbivores, the feeding preference and performance of a mix of orthopteran species were investigated. The selenium hyperaccumulator Stanleya pinnata and accumulator Brassica juncea were used in herbivory studies in the laboratory, and S. pinnata was also used in a manipulative field...

Selenium is an integral part of the human antioxidant system. Both hemodialysis (HD) and peritoneal dialysis (PD) patients are deficient in selenium and its subsequent enzymes, compared to a healthy population. Few selenium supplementation trials have been conducted to evaluate its effect on enzymes, markers of peroxidation and clinical health outcomes in dialysis patients. Introduction Seleniu...

Selenium, a trace mineral complement is used as cofactor of antioxidant enzymes that protects fishes against environmental stress agents and enhances performance in fishes. In this study the different levels of organic and inorganic source of  selenium were included in juvenile rainbow trout diet to evaluate feed conversion ratio (FCR), specific growth rate (SGR), weight gain percent (WG), cond...
