Article Synopsis
- The developing fetus is highly sensitive to neurotoxic metals, and this study uses placenta as a key biomarker for monitoring such exposures during pregnancy.
- Conducted as part of the Ma'anshan Birth Cohort (MABC) in China, the research analyzed the effects of both non-essential and essential metals (like arsenic, cadmium, mercury, and zinc) on cognitive development in children, involving 1,586 mother-child pairs.
- Results showed negative associations between elevated levels of certain metals, especially arsenic and cadmium, with cognitive tasks measured by the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV), with findings also indicating varied effects based on the sex of the children.

The complex hemodynamic environment within the aortic lumen plays a crucial role in the progression of aortic diseases such as aneurysms and dissections. Traditional imaging modalities often fail to provide comprehensive flow dynamics that are essential for precise risk assessment and timely intervention. The advent of time-resolved, three-dimensional (3D) phase-contrast magnetic resonance imaging (4D flow MRI) has revolutionized the evaluation of aortic diseases by allowing a detailed visualizations of flow patterns and quantification of hemodynamic parameters.

Microbial reduction of selenium oxyanions, highly soluble, mobile and toxic inorganic selenium compounds, to insoluble selenium nanoparticles (Se NPs) is a widely spread phenomenon which is of geochemical, environmental and biotechnological importance. While selenite bioreduction is known for a wide variety of microorganisms, selenate bioreduction is not so common and has mostly been documented for anaerobes, with merely a few reported cases related to aerobic or microaerobic conditions. In some biogenic Se NPs of microbial origin, the presence of sulfur was detected together with selenium in Se NPs, particularly when increased concentrations of sulfate were present in the medium.

As an alternative to the criticized antibiotics, probiotics have been adopted for their eco-friendly nature and ability to enhance host growth and immunity. Nevertheless, reports suggest ineffectiveness in commercially available probiotics since most are from non-fish sources; thus, this study was envisaged to isolate and characterize new Bacillus spp. from the gut of hybrid grouper (Epinephelus fuscoguttatus♀ × Epinephelus lanceolatus♂) which could serve as potential probiotics.
