Toxicity of Aqueous L-Selenomethionine and Tert-Butyl Hydroperoxide Exposure to Zebrafish (Danio rerio) Embryos Following Tert-Butyl Hydroquinone Treatment

Toxics, 2019
Aqueous L-selenomethionine (SeMet) embryo exposures represent a rapid and simplified method for investigating the embryotoxic effects of SeMet. Using zebrafish (Danio rerio) as a model organism, the objective of the present study was to characterize the ...

The High-Affinity E. coli Methionine ABC Transporter: Structure and Allosteric Regulation [PDF]

, 2008
The crystal structure of the high-affinity Escherichia coli MetNI methionine uptake transporter, a member of the adenosine triphosphate (ATP)–binding cassette (ABC) family, has been solved to 3.7 angstrom resolution.

Assessment of platelet production with 75Se selenomethionine [PDF]

BMJ, 1969
Incorporation of intravenously injected (75)Se selenomethionine into platelets has been found to vary with alterations in the rate of platelet production. It appears to label newly produced platelets during their formation in megakaryocytes and provides a method by which thrombopoiesis may be studied in vivo.

Role of the IL-6/STAT3 Signaling Axis in the Protective Effect of Selenomethionine Against Zearalenone-Induced Hepatic Inflammatory Injury in Rabbits

Toxins
Zearalenone (ZEA), a mycotoxin primarily generated by the Fusarium species, constitutes a prevalent contaminant in both human and animal feedstuffs. Chronic exposure to this mycotoxin induces hepatic inflammatory responses in livestock species including ...

Selenium Biotransformations in an Engineered Aquatic Ecosystem for Bioremediation of Agricultural Wastewater via Brine Shrimp Production [PDF]

, 2013
An engineered aquatic ecosystem was specifically designed to bioremediate selenium (Se), occurring as oxidized inorganic selenate from hypersalinized agricultural drainage water while producing brine shrimp enriched in organic Se and omega-3 and omega-6 ...

Fortification of White Wines with Antioxidants and Se: Impacts on Browning Development and Phenolic Content

Beverages
The present study explores the efficiency of selenomethionine (Semeth), an organic form of Se, as an antioxidant compared with commonly used antioxidants (ascorbic acid, glutathione, and potassium metabisulfite) in preventing oxidative browning in Greek ...

Absorption and Biotransformation of Selenomethionine and Selenomethionine-Oxide by Wheat Seedlings (Triticum aestivum L.)

Plants
An in-depth understanding of Se uptake and metabolism in plants is necessary for developing Se biofortification strategies. Thus, hydroponic experiments were conducted to investigate the associated processes and mechanisms of organic Se (selenomethionine (SeMet) and selenomethionine-oxide (SeOMet)) uptake, translocation, transformation and their ...
