A previous communication [1] described the preparation of the double selenates of lanthanum and the alkali metals; the La-Li compound has the formula La2(SeO4)3 · Li2SeO4 · 8H2O. Subsequent reports [2–4] have shown that it was not possible to prepare the Ce-Li, Pr-Li, Nd-Li and Sm-Li double s...

Polarized Raman spectra were measured in single crystals of lithium sulfate doped with different concentrations of lithium selenate. Weak features observed in the Ag scattering geometry on the low-frequency side of the sulfate ionν1 mode were identified as originating in theν1 andν3 intramole...

Three rare-earth oxide selenates Ln2O2SeO4 (Ln = La, Pr, Nd) have been prepared via double-exchange solid-state reactions between respective LnOCl oxyhalides and potassium selenate. This approach succeeded to obtain single-phase specimens of La2O2SeO4 and Nd2O2SeO4, previously known as transient...

l-Tryptophanium hydrogen selenite was synthesised and structurally characterised at room and low temperature. The aminoacid is positively charged with the amine and carboxylic group protonated. It adopts a staggered conformation with the N1 gauche to C4 that is gauche to C1. The anion displays a...

Process of dehydration in polycrystalline hydrogen selenites of alkali metals MeHSeO3 (Me=Li, Na, K, Cs) has been studied by the method of a proton magnetic resonance. It is shown that the method allows not only to designate a temperature interval of dehydration, but also to observe the dynamics...

The study was conducted to compare effects of different dietary Se sources (sodium selenite [NaSe], Se-enriched yeast [Se yeast] or L-selenomethionine [SeMet]) and one Se-deficient control diet on the expression of selected genes, hematological and clinical biochemical parameters, and muscle mor...

Selenium (Se) is an essential micronutrient, but also a potential toxin, which may be absorbed in excess. Relatively little is known about selenium embryotoxicity in zebrafish. In this study, we evaluated the effect of selenite exposure in zebrafish embryos. Selenite treatment decreased survival...

AimsSelenium is an essential element possessing antioxidant properties and the treatment with it has displayed protective effects against toxicity of different substances occurring in the environment and food as well as against the side effects of some drugs. Lithium is used in medicine although...

A field study in periparturient sows fed different dietary concentrations of either sodium selenite or L-selenomethionine (SeMet) was conducted to evaluate feed intake, haematological and biochemical parameters as well as to describe some key selenium (Se) species, namely selenoprotein P (SelP),...

BackgroundSelenium is an essential element which shows protective properties against diverse harmful factors. Lithium compounds are widely used in medicine, but, in spite of undoubted beneficial effects, treatment with these compounds may lead to severe side effects, including renal, gastrointes...

PurposeWe examined in a longitudinal study the role of sodium selenite in sepsis patients in strengthening the immune performance in whole blood samples using immune functional assays.

BackgroundSelenium is an essential element of antioxidant properties. Lithium is widely used in medicine but its administration can cause numerous side effects including oxidative stress. The present study aimed at evaluating if sodium selenite could influence chosen anti- and pro-oxidant parame...

Lithium ionic sieve precursor Li2TiO3 was synthesized by a solid-phase reaction with Li2CO3 and TiO2 as the raw materials. The effect of the roasting temperature, the roasting time and the molar ratio of Li2CO3/TiO2 on the synthesis of precursor were investigated respectively. The precursor was ...
