The effect of selenium-containing compounds (5-oxa-2,8-diselenanonane, 6-oxa-3,9-diselenaundecane) on the process brilliant nickel plating has been studied. Additives have Optimal concentrations organic additives and electrolysis modes were selected, allowing to obtain a shiny coating

Selenium compounds have a checkered history. Originally considered to be highly toxic, the tide turned in 20th century when selenium was discovered an essential trace element; indeed, is least abundant element on Earth well-defined biological role. Despite this new-found importance, organoselenium were largely curiosities because methods for their synthesis cumbersome and unpleasant often invol...

Selenium-accumulator plants synthesize selenium compounds that differ from those produced by nonaccumulators. To determine if there are any subcellular differences between accumulators and nonaccumulators in the use of selenomethionine in vitro, polysomes from Astragalus crotalariae (accumulator) and Astragalus lentiginosis (nonaccumulator) were translated in the presence of selenomethionine. P...

Organothiocyanate and organoselenocyanate compounds are of paramount importance in organic chemistry as they key intermediates to access sulfur- selenium-containing compounds. Therefore, among the different synthetic pathways get SCN- SeCN-containing molecules, original methodologies using electrophilic reagents have recently been explored. This Minireview will showcase recent advances that mad...

Shewanella sp. HN-41 was exploited for selenium nanoparticles synthesis from aqueous selenite compounds under anaerobic conditions. Various reaction conditions, including reaction time, initial biomass, and initial selenite concentration, were systematically investigated to determine their effects on particle size distribution and formation rate. The biomass concentration of Shewanella sp. HN-4...

The synthesis of the selenium-based ligand L1SeSeL1 (2,2’-diselanediylbis(N,N-bis(pyridin-2-ylmethyl)ethan-1-amine) is described along with its reactivity cobalt(II) salts. cobalt(II)-diselenide complex [Co2(L1SeSeL1)Cl4] was obtained in good yield, and spectroscopic properties closely resemble that sulfur analog. Reaction Co(II) thiocyanate results formation cobalt(III) compound [Co(L1Se)(NCS)...

AIM To study liver cell apoptosis caused by the toxicity of selenium and observe the alteration of choline compounds using in vitro 9.4T high resolution magnetic resonance spectroscopy. METHODS Twenty male Wistar rats were randomly divided into two groups. The rats in the treatment group were intraperitoneally injected with sodium selenite and the control group with distilled water. All rats ...

A higher risk of more-aggressive prostate cancer was seen in men with a certain genetic variant found in about 75 percent of the prostate cancer patients in the study. In those subjects, having a high level of selenium in the blood was associated with a two-fold greater risk of poorer outcomes than men with the lowest amounts of selenium. By contrast, the 25 percent of men with a different vari...

Angiotensin converting enzyme (ACE) catalyzes the conversion of angiotensin I (Ang I) to angiotensin II (Ang II). ACE also cleaves the terminal dipeptide of vasodilating hormone bradykinin (a nonapeptide) to inactivate this hormone. Therefore, inhibition of ACE is generally used as one of the methods for the treatment of hypertension. 'Oxidative stress' is another disease state caused by an imb...
