Summary: This study successfully synthesized nano-hydroxyapatite biomimetically and found that the morphology, crystallinity, and specific surface area of the synthesized CS/HAP nanorods influenced their U(VI) adsorption efficiency. The CS/HAP-40 with smaller particle size, lower crystallinity, and larger specific surface area exhibited higher removal efficiency for U(VI). Additionally, the removal mechanism of U(VI) in acidic and alkaline solutions differed.

Summary: In this study, composite structures made of hydroxyapatite scaffold impregnated with a collagen slurry were designed to mimic bone tissue structure, with the addition of magnesium and silicon ions enhancing mechanical and biological properties. An innovative freeze-drying approach was developed to create open-pore structures for tissue regeneration. The biodegradation behavior of the scaffolds, particularly HA-Mg_Coll scaffolds, showed moderate weight loss and mechanical performance reduction due to collagen dissolution, while also protecting the ceramic structure until degradation, making them suitable candidates for bone remodeling.

Summary: Three magnetic biochar-supported nano-hydroxyapatite materials were prepared with different magnetic sources, exhibiting excellent reusability and adsorption ability. The composite with nickel chloride as the magnetic source achieved a maximum adsorption capacity of 1723.5 mg/g, meeting the discharge limit standard for uranium-containing wastewater in China. The composite showed high removal efficiencies for uranium in different water systems, surpassing 90.2%, and maintained its magnetism after eight cycles of reuse. The strong chemical reactions between active sites and uranium were responsible for its outstanding adsorption ability.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
