Summary: This study investigated the characteristics of Se enrichment in the water-soil-plant system, as well as the dietary Se status of local residents in seleniferous areas. The results showed that Se in well water mainly came from Se-enriched shales and coals, and the mobility of Se in seleniferous soils was relatively low. The concentration of Se in edible parts of crops varied widely, with cereal plants having a higher Se-enrichment ability than tuber plants. The probable dietary Se intake in high-Se areas has decreased in recent years but still exceeds the permissible value. Reducing cereal-derived dietary Se intake is an important strategy to improve the Se nutrition status in high-Se areas.

Summary: Chen et al. reported a zinc/selenium conversion battery with a high discharge working voltage of about 1.15 V. However, based on theoretical calculations, the discharge voltage of this battery should not exceed 0.71 V. In addition, the data presented by the author in Figures S11, S14, and S23 are inconsistent with previous reports and experimental results, raising doubts about their explanations and core conclusions. Finally, it is found that the main contribution to capacity and voltage comes from the conversion reaction between ZnSe and Se(TFSI)(4).

Summary: Selenium is an essential trace element involved in the synthesis of selenoproteins in higher animals, with organic selenium considered safer than inorganic selenium. While super-nutritional intake of selenium has been claimed to prevent cancer, consistent clinical results are lacking. In selenium-deficient areas, consuming selenium-rich foods may be the safest and best recommendation.

Summary: This study developed an innovative oral hydrogel microbeads-based biochemical strategy for in situ synthesis of selenoproteins, which effectively bypassed the limitations of oral protein delivery and generated therapeutic selenoproteins. The strategy was tested in mice with inflammatory bowel disease, showing significant reduction in proinflammatory cytokine secretion, modulation of immune cells, and regulation of gut microbiota composition to relieve colitis-associated symptoms and maintain intestinal homeostasis. This in situ selenoprotein synthesis strategy has the potential to be applied to various diseases associated with intestinal immunity and microbiota.

Summary: Selenium is an essential micronutrient that plays an important role in the development and physiological homoeostasis of animals and humans. This review discusses the role of selenium in the environment, plants, and animal bodies and explores different sources of selenium supplementation, focusing on Se-enriched yeast. Other potential sources such as Se-enriched insects and Se-nanoparticles are also examined for their use in animal nutrition. The scientific evidence suggests that sodium selenite and Se-yeast are the main options for inorganic and organic selenium supplementation, but further research is being conducted on alternative sources with high bioavailability and reduced environmental emissions.

Summary: In recent years, microbial conversion of inorganic selenium into a safe and efficient form of organic selenium has been a focus of research. Selenium nanoparticles derived from nanotechnology offer higher safety, absorption, and biological activity compared to other selenium forms. This paper reviews the conversion of inorganic selenium to less toxic organic selenium and the biosynthesis of selenium nanoparticles by microbes. The synthesis method, potential mechanism, and characterization of selenium in different forms are also discussed.

Summary: Selenium (Se) deficiency affects millions of people globally, and the volatilization of Se to the atmosphere may hinder its entry into the food chain. Laboratory experiments have shown that the sulfur (S) status of bacteria plays a crucial role in determining the amount of Se volatilized, shedding light on the fluxes of Se in the environment.

Summary: Selenium is an important micronutrient involved in various biological processes, and its deficiency can increase the risk of HIV infection, cancer, cardiovascular disease, and inflammatory bowel disease. Selenium has antioxidant, anticancer, immunomodulatory, hypoglycemic, and intestinal microbiota-regulating properties. The relationship between selenium status and health effects is U-shaped, and individuals with low baseline selenium levels may benefit from supplementation, while those with acceptable or high selenium levels may face potential health hazards. Selenium supplementation is beneficial in various populations and conditions, but its safety is still a subject of debate due to the narrow safety window.

Summary: Selenium is an essential micronutrient for mammals, with deficiency posing a serious threat to health. Biofortification strategies have been developed to combat selenium deficiency. While selenium supplementation is beneficial for preventing and treating chronic diseases, the effects may vary depending on individual baseline selenium status.

Summary: The biotransformation of toxic selenium ions into non-toxic species has been a focus of research in biofortification and production of selenium nanoparticles (SeNPs), with less attention given to the mechanisms of transformation. In this study, a combination of analytical techniques was used to characterize SeNPs and monitor selenium transformation in the fungus Phycomyces blakesleeanus. The results showed the formation of SeNPs and volatile methylated selenium compounds after only a few hours of incubation. Different structural forms of elemental selenium were also detected.

Summary: In this study, it was found that junctional rhythm (JR) is necessary for successful catheter ablation of AVNRT. The cycle length of JR during radiofrequency (RF) was not predictive of success. Unintended junctional beat-atrial block during faster JR was associated with slow pathway block, but it should not be intentionally targeted as it is a precursor to fast pathway block.

Summary: This study compared the effects of higher power short duration (HPSD) and lower power longer duration (LPLD) radiofrequency ablation on the risk of oesophageal thermal injury (ETI) in atrial fibrillation (AF) patients. It found that both methods had similar rates of ETI, but HPSD ablation reduced the ablation time and AF recurrence rate.

Summary: This study aims to evaluate the associations between different types of coffee and incident outcomes. Findings show that decaffeinated, ground, and instant coffee, especially at 2-3 cups/day, are associated with significant reductions in cardiovascular disease and mortality. Ground and instant coffee are also associated with reduced arrhythmia.

Summary: This study reviewed the diagnostic work-up of cardiac arrest patients with ventricular tachyarrhythmias and normal hearts. The results showed that the work-up was often incomplete, especially in younger adults. The utilization of second-line cardiac investigations, such as cardiac magnetic resonance imaging (CMR), was low, and there is a need for further study to establish a systematic diagnostic protocol.
