BACKGROUND: Several studies have suggested that selenium may influence the natural history of autoimmune thyroiditis (AIT). Recently, IFNγ-inducible chemokines (CXCL-9, -10 and -11) were shown to be elevated in AIT patients.OBJECTIVE: This prospective, randomized, controlled study was conducted to...

An on-line system for the simultaneous determination of Se(IV), Se(VI) and selenomethionine (Se-Met) in aqueous samples was developed, consisting of separation by ion chromatography, microwave digestion and detection by hydride generation atomic absorption spectrometry. 8.3 mmol/l Na(2)HPO(4) (pH 9.2)...

Rapid microalgal metabolism of selenate to volatile dimethylselenide.

Plant, cell & environment

Plant Cell Environ. 2003 Jun;26(6):897-905. doi: 10.1046/j.1365-3040.2003.01022.x.

An axenically cultured isolate of single-celled freshwater microalgae (Chlorella sp.) metabolized toxic selenate to volatile dimethylselenide at exceptionally high rates when transferred from mineral-nutrient solution to water for 24 h. The Se-volatilization rates were orders of magnitude higher than...

Vigna radiata polysomes efficiently incorporated [(75)Se]selenomethionine, [(14)C]methionine, and [(14)C]leucine in vitro. The optimal conditions for translation were determined to be 4.8 millimolar Mg(2+), 182 millimolar K(+), and pH 7.4. The rates of incorporation of [(75)Se]selenomethionine and [(14)C]methionine were similar...
