Summary: This study demonstrates the use of selenium nanoparticles (SeNPs) to increase biomass productivity and lipid production, as well as enhance cadmium tolerance in microalgae. SeNPs improve cell growth and cadmium tolerance by upregulating photosynthesis, the TCA cycle, and the antioxidant system, reducing cadmium uptake and translocation, and decreasing oxidative stress levels. The presence of both SeNPs and cadmium stress leads to higher energy yield and lipid content.

Summary: The study demonstrated that the application of exogenous Se or Cd in rice reduces the uptake and transport of the other element. When the molar ratio of Se/Cd was higher than 1, Cd absorption in rice reached the lowest level, while Se absorption was lowest when Cd/Se ratio was greater than 20. Additionally, a 1:1 Se/Cd ratio was observed in roots, indicating that the addition of exogenous Cd or Se promotes the enrichment of the other element in roots.

Summary: It has been reported that selenium has an antagonistic effect on heavy metals in animals. This study aimed to investigate whether selenium could protect against the pulmonary toxicity of cadmium and lead. The results showed that moderate selenium intake attenuated the harmful effects of cadmium and lead on lung function.

Summary: The study demonstrated that selenium has a protective effect against cadmium-induced oxidative stress and autophagy in the brain. Selenium treatment can inhibit cadmium-induced degenerative changes in cells and restore the balance of the redox system. Furthermore, selenium can also suppress cadmium-induced autophagy and activation of the Nrf2 signaling pathway.

Summary: Cadmium has a significant impact on agricultural production, but selenium can alleviate its toxicity. This study aimed to investigate the effects of selenium on cadmium-induced heart injury and found that selenium may protect the heart from cadmium-induced pyroptosis, autophagy, and apoptosis by interfering with the PI3K/AKT/PTEN signaling pathway.

Summary: It was found that under Cd stress, rice grain quality and quantity are compromised, affecting human health. Previous research has shown that Selenium (Se) can mitigate Cd stress in rice, but its role in rescuing Cd-induced damage in the reproductive parts of rice plants has not been studied. This study investigated the mechanism of Se-mediated alleviation of Cd-stress induced damage to pollen viability, germination rate, and grain chalkiness. The results showed that Se supplementation decreased ROS accumulation in the reproductive parts, improved pollen viability and germination rate, and prevented Cd translocation from leaves to grains. Therefore, foliar spray of Se could be a cost-effective strategy to prevent Cd-induced yield loss and quality reduction in rice.

Summary: The study found an inverse relationship between plasma selenium levels and RCC, while a direct relationship was observed between red blood cell cadmium levels and RCC. Low plasma selenium levels may interact with high total urinary arsenic levels or high red blood cell cadmium concentration to increase the risk of RCC. The multiplicative interaction between low eGFR and high red blood cell cadmium concentration may further increase the risk of RCC.

Summary: This study investigates the interactive effects of iron plaque, selenium, and cadmium on the uptake of selenium and cadmium in rice seedlings. The formation of iron plaque reduces cadmium uptake by inhibiting its adsorption onto the root surface and increasing its retention in the iron plaque. The root system is also found to play a role in inhibiting cadmium uptake, mediated by selenium. This research provides new insights into the remediation of cadmium-contaminated and cadmium-contaminated seleniferous areas.

Summary: In this study, a high surface area nanoporous carbon derived from MOF-5 was used as a hard template for the synthesis of TiO2 nanoparticles by nanocasting. The interconnected mesoporous network of the carbon template led to the formation of brookite and anatase TiO2 with highly developed mesoporous and macroporous structures. Furthermore, the fabricated brookite and anatase showed enhanced photocatalytic efficiency in visible light due to increased light harvesting ability and reduced band gap energy.
