Summary: This study found widespread selenium deficiency in Lusaka province, Zambia, with low selenium concentrations in both adults and children. Low socioeconomic status was associated with selenium deficiency, and there was a positive correlation between children's selenium concentrations and age. Supplementation or agronomic biofortification may be needed to address the selenium deficiency.

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 a vital element for human and animal health, playing a significant role in various bodily functions. However, excessive intake of selenium can be harmful. It supports antioxidant defense systems, hormone metabolism, reproductive functions, and neuroprotection. Optimizing selenium intake is important for preventing diseases related to selenium deficiency or excess.

Summary: Grains are an important part of the diet for rural residents in Tibet, but the lack of selenium and zinc in these grains poses a threat to their nutrition and health. A study was conducted to understand the intake of selenium and zinc from staple grains in residents along the Yarlung Zangbo River. The results showed that a majority of self-produced tsampa and flour had low selenium concentrations, and the intake of selenium and zinc from staple grains contributed only a portion of the recommended nutrient intake.

Summary: The study found that selenium deficiency was common among Chinese pregnant women, but low serum selenium levels during early pregnancy may not be a strong predictor of the risk of GDM and preterm birth. Larger population studies are needed to further investigate this relationship.

Summary: This study observed alterations in metallomic profiles in the Huntington's disease (HD) brain, which may contribute to various pathogenic mechanisms. Selenium supplementation could offer a potential therapeutic pathway for HD treatment, as selenium deficiency is widespread in regions with differing levels of neurodegeneration.

Summary: The increase in life expectancy can be attributed to the world's socioeconomic, sanitary, and nutritional conditions. A higher diversity score in diet has been shown to reduce the risk of malnutrition and improve health status. Zinc and selenium deficiencies can lead to immune system abnormalities and increased susceptibility to infections.

Summary: Selenium is a nonmetallic element that is essential for the proper functioning of plants and animals. Research indicates that selenium plays a necessary role in metabolic pathways in animals and is a key component in immune system, antioxidant homeostasis, and inflammatory mediator release. Finding the appropriate selenium dosage is crucial for eliminating physiological disorders associated with selenium imbalance.

Summary: Micronutrient deficiencies are widespread among people in sub-Saharan Africa due to limited access to micronutrient-rich food sources. Research in Ethiopia and Malawi shows geographical variation in the micronutrient composition of staple cereal grains, influenced by soil and environmental factors. Understanding these geographical effects is crucial for designing interventions to alleviate micronutrient deficiencies.

Summary: Mineral deficiencies are widespread in small ruminant herds globally and play a significant role in herd health management. This paper reports the first proven case of multiple trace element deficiencies in German sheep in decades, including primary molybdenosis, secondary copper deficiency, Ovine White Liver Disease, and selenium deficiency. The severity of these deficiencies in a small pedigree herd in Germany may be attributed to heavy metal inputs from surrounding industries, non-fertilised soil, and monoculture grass species.

Summary: The study found that selenium deficiency upregulates ATG7 expression, while miR-17-5p inhibits cardiomyocyte autophagy by targeting ATG7. Additionally, LncRNA 0003250 regulates miR-17-5p, thereby affecting ATG7 and autophagic cell death.

Summary: The study demonstrates the importance of selenium and iodine for the health of schoolchildren, with some students showing deficiencies in iodine and selenium levels. There is a positive correlation between selenium and iodine, suggesting the need to consider measuring selenium in monitoring programs.
