Selenium (Se) is an essential trace mineral required for growth, development, immune function, and metabolism. Selenium exerts its biological effects as an integral component of selenoproteins (SePs). Deficiency or low Se status leads to marked changes in many biochemical pathways and a range of pathologies and disorders which are associated with SeP function. Animals, and presumably humans, ar...

Many of the benefits of the antioxidant selenium can be attributed to its incorporation into selenoenzymes as the 21st amino acid, selenocysteine. Selenocysteine incorporation occurs cotranslationally at UGA codons in a subset of messages in prokaryotes, eukaryotes, and archaea. UGA codons are recoded to specify selenocysteine, rather than termination, by the presence of specialized cisand tran...

This study was conducted to determine the effects of either dietary Se source or dose on the Se status of horses. Twenty-five mature horses were blocked by BW and randomly allocated to 1 of 5 dietary treatments that comprised the same basal diet that differed only in Se source or dose. Treatments were as follows: negative control (0.085 mg of Se/kg of DM), 3 different dietary concentrations of ...

The effect of dietary riboflavin (B2) supplementation and selenium (Se) source on the performance and Se metabolism of weanling pigs was studied. Pigs fed a B2-supplemented (10 mg/kg) casein-glucose diet for 18 d gained faster than pigs fed the B2-unsupplemented diet. Percentage active erythrocyte glutathione reductase (GR) declined rapidly when pigs were placed on the B2-unsupplemented diet an...

Testing is one of the important aspects of Software Engineering and there is wide availability of open source software testing tools in this category of which Selenium, Sikuli and Watir are usually used open source automated testing tools. This paper presents the comparative analysis of these different tools in terms of their recording capabilities, Data Driven Testing, Efficiency, Languages Su...
