Determination of selenium by GFAAS in slurries of fish feces to estimate the bioavailability of this micronutrient in feed used in pisciculture
(Elsevier B.V., 2007-07-01)
This paper presents a simple, fast and sensitive method to determine selenium in samples of feces and of fish feed by graphite furnace atomic absorption spectrometry (GFAAS) through the direct introduction of slurries of ...
Chemoenzymatic approaches to obtain chiral-centered selenium compounds
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012-12)
The synthesis of chiral-centered selenium compounds is presented. Enantioselective oxidations of these organoselenium compounds were performed using a wide range of biocatalysts, including Baeyer-Villiger monooxygenases, ...
Crystallization at room temperature from amorphous to trigonal selenium as a byproduct of the synthesis of water dispersible zinc selenide
(Elsevier B.V., 2012-11-15)
Zinc selenide is a semiconductor material that has been synthesized in aqueous media. However, this synthesis can yield some byproducts, which has been little exploited in literature of this area; one of these byproducts ...

Influence of HIV infection and the use of antiretroviral therapy on selenium and selenomethionine concentrations and antioxidant protection
(2016-12-01)
Objective The aim of the present study was to evaluate whether HIV infection and antiretroviral therapy (ART) use are associated with oxidative stress, concentrations of selenium and selenomethionine, and antioxidant ...
Zinc and selenium status in critically ill patients according to severity stratification
(2018-01-01)
Objective The aim of this study was to evaluate the concentrations of zinc and selenium in different biological materials and to associate them with the clinical severity score according to the Simplified Acute Physiology ...
Synthesis of selenium-linked neoglycoconjugates and pseudodisaccharides
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The introduction of organoselenium moieties within the structure of carbohydrates has received attention recently. Herein, we report on the synthesis of selenium-containing neoglycoconjugates and pseudodisaccharides by the ...
