Summary: This study aimed to compare the bio-efficacy of different inorganic and organic Se compounds, with results showing that the bio-efficacy of organic Se supplements for chickens depends on the proportion of SeMet, and there is bioequivalence between pure forms of organic Se and between L-SeMet and OH-SeMet.

Summary: This study aims to determine the amount of selenium transferred to milk and blood of dairy cows when fed with hydroxy-selenomethionine (OH-SeMet) compared to unsupplemented and seleno-yeast (SY) groups. The results showed that organic selenium supplementation increased selenium concentrations in milk and plasma, and OH-SeMet was more effective than SY in improving milk quality.

Summary: This article summarizes the synthetic methodologies of selenium-containing peptides and provides a brief description of their chemistry and biological activities. These methodologies enable the access to various natural and unnatural selenium-containing peptides that have been used in a range of applications, from modulating protein characteristics to structure-activity relationship studies for applications in nutraceuticals and drug development.

Summary: This study assessed the effects of 10-HDA on the growth performance, antioxidant capacity, and immunity of broiler chickens. The results showed that a diet supplemented with 10-HDA significantly improved the average daily gain, immunocompetence, and antioxidant capacity of the broiler chickens.

Summary: This study found that supplementing hydroxy selenomethionine (OH-SeMet) can increase selenium deposition in breast muscle, improve meat quality, enhance antioxidant capability, and regulate selenoprotein encoding gene expression in native yellow-feathered broiler birds.

Summary: This review synthesizes current knowledge on selenium transport and metabolism in plants, emphasizing the importance of selenium for biofortification and phytoremediation. Plant uptake and translocation of selenium are largely achieved through sulfur transport proteins, with selenium metabolism closely following the sulfur metabolic pathway. Unique aspects of selenium transport and metabolism in selenium hyperaccumulators are also discussed, highlighting their potential applications for biofortification and phytoremediation.

Summary: Through studying Se kinetics in humans before and after supplementation with SeMet, it was found that Se absorption increased but not all absorbed Se was excreted in urine. The size of some Se plasma pools increased after supplementation, indicating a net incorporation of SeMet into various body pools.

Summary: Lactic acid bacteria (LAB) exhibit resistance to sodium selenite concentrations above 100 mg/L. This study confirmed the presence of selenocysteine in Enterococcus faecium ABMC-05. The microorganism was cultured in a medium with a minimum inhibitory concentration of 184 mg/L sodium selenite, and the absorption of selenium and its conversion into selenocysteine were determined using ICP-OES and RP-HPLC, respectively. PCR analysis revealed the presence of the cysK gene and the absence of the selD and selA genes. The results demonstrate that this microorganism produces selenocysteine through a pathway independent of SelA and SelD, unlike other LAB.

Summary: This study found that the metabolism and accumulation of selenomethionine in rats is different from that of selenocysteine. At the selenium requirement for maximal glutathione peroxidase activity, selenocysteine is the major selenium species, while at higher intakes of selenomethionine, it is metabolized into low molecular weight selenosugars and selenosugar-decorated proteins. Additionally, compared to selenite, selenomethionine leads to less binding of inorganic selenium to liver proteins.

Summary: This study successfully redirected selenium flow in rice by overexpressing the genes encoding selenocysteine lyase and selenocysteine methyltransferase. Transgenic plants showed lower sensitivity to selenium stress and increased tolerance to selenate and selenite, as well as improved selenium elimination capabilities. These findings suggest that genetically modified plants have the potential to restore selenium-contaminated environments.

Summary: This study investigated the removal of organoselenium from wastewater using nanoscale zerovalent iron particles immobilized on coconut shell-based granular activated carbon. The results showed that the composite adsorbent had a strong affinity for adsorbing selenomethionine and selenocysteine, with removal efficiencies of 78.2% and 99.9% respectively. Kinetic and isotherm models supported the efficient adsorption of the organoselenium by the composite adsorbent.

Summary: This study aimed to evaluate the efficacy of synthetic methionine sources and determine the differences in growth rate of broiler chickens fed at or below requirements. Through database analysis and model fitting, it was found that there were no significant differences between linear and quadratic plateau models in determining methionine or sulfur amino acid requirements during different growth phases. Additionally, there was no difference in body weight gain response of broiler chickens to the two sources when fed at or below requirements for any of the growth phases.

Summary: This study investigates the effect of 4-phenylbutyric acid (4-PBA), a chemical chaperone that reduces endoplasmic reticulum (ER) stress, on broiler chickens under heat stress (HS). The results show that 4-PBA supplementation alleviates HS-induced ER stress response in skeletal muscle and decreases body temperature elevation in HS birds. Furthermore, 4-PBA prevents HS-induced gene elevation of ER stress markers in the skeletal muscle.
