A series of zirconium-based, metal-organic frameworks (MOFs) were tested for their ability to adsorb and remove selenate and selenite anions from aqueous solutions. MOFs were tested for adsorption capacity and uptake time at different concentrations. NU-1000 was shown to have the highest adsorption capacity, and fastest uptake rates for both selenate and selenite, of all zirconium-based MOFs st...

Although supplementation with the selenocompound, sodium selenite has been shown to stimulate the concanavalin A-induced T-cell mitogenic response, the mechanisms responsible remain unclear. This study was conducted to evaluate the relationships between the induction of apoptosis, formation of tumor necrosis factor (TNF)-alpha and reactive oxygen species (ROS), activation of apoptosis signal-re...

A selenium-binding protein (SeBP) from Methanococcus vannielii was recently identified, and its gene was isolated and overexpressed in Escherichia coli [Self, W. T., Pierce, R. & Stadtman, T. C. (2004) IUBMB Life 56, 501-507]. SeBP and recombinant SeBP (rSeBP) migrated as approximately 42-kDa species on native gels and as approximately 33-kDa species on SDS gels. rSeBP consists of identical 8.8...

Objective- This study aimed at evaluation of histopathological findings of application of chitosan- nano selenium biodegradable film on full thickness excisional wound healing in rats. Design- Experimental Study Animals- Seventy-two male Wistar rats Procedures- Animals were randomized into six groups of 12 animals each. Group I: Animals with created wounds and no...

Various mechanisms have been proposed to explain the biological dissimilatory reduction of selenite (SeO3(2-)) to elemental selenium (Se(o)), although none is without controversy. Glutathione, the most abundant thiol in the eukaryotic cells, the cyanobacteria, and the alpha, beta, and gamma groups of the proteobacteria, has long been suspected to be involved in selenium metabolism. Experiments ...

Selenium has been shown to inhibit L1210 cells both in vitro and in vivo. The death of L1210 cells in vitro as indicated by trypan blue exclusion was dependent upon the form and con centration of selenium tested. Incubation of L1210 cells in buffer containing selenium at 1 jug/ml for 1 hr prior to inocula tion into mice significantly retarded the ability of the cells to propagate in vivo. Sodiu...

Abstract A total of 3,888 pigs (337×1050, PIC, Hendersonville, TN; 6.0 kg at weaning) were used in a 42-d study to determine the influence Se source on nursery pig selenium status and growth performance. At placement, pens weighed allotted 1 3 dietary treatments randomized complete block design with blocking structure including sow farm origin, date entry, average pen BW. 144 72 double-sided 5-...

Selenium has been shown to inhibit L1210 cells both in vitro and in vivo. The death of L1210 cells in vitro as indicated by trypan blue exclusion was dependent upon the form and concentration of selenium tested. Incubation of L1210 cells in buffer containing selenium at 1 microgram/ml for 1 hr prior to inoculation into mice significantly retarded the ability of the cells to propagate in vivo. S...
