Summary: In this study, a novel magnetic cation exchange resin (MCER resin) was developed for the selective adsorption of basic amino acids, histidine and arginine, which effectively reduced the generation of disinfection by-products (DBPs). The MCER resin exhibited high resistance to the interference of cations and had promising potential for simultaneous removal of hardness. The adsorption of histidine and arginine followed pseudo-first order and intra-particle diffusion kinetic models, and the selective adsorption mechanism was determined through electrostatic attraction, hydrogen bonding, and ion exchange.

Summary: Mass cytometry is an emerging technique for high-dimensional single-cell analysis that uses metal-isotope-tagged antibodies and a mass spectrometer for cell staining and analysis. The synthesis and characterization of a new type of metal-chelating polymer with pendant dipicolylamine chelators, suited for binding intermediate to soft metals, is described. These polymers can serve as new elemental mass tags for mass cytometry, enabling multi-parameter single-cell immunoassays.

Summary: The potential of Pd/Pt complexes for catalytic carboxylation of arenes with CO2 was investigated using computational chemistry. The influence of geometric and electronic factors of various ligands and substrates on the overall activation barrier of a potential catalytic cycle, as well as the tendency of key intermediates to dimerize and the role of the base, were studied. Pd and Pt complexes I(Pd)-L16-S1 and I(Pt)-L16-S1 were found to have low energy span values and can enable the computation of complete catalytic cycles without dimerization.

Summary: The effects of different ancillary ligands and counterions on the photophysical properties of platinum(II) complexes were investigated. It was found that changing the fourth ligand in the platinum(II) complexes resulted in varying lifetimes and quantum yields. The study also revealed that the emission of the complexes is mainly influenced by the tridentate luminophore, with minimal contribution from the ancillary ligand.

Summary: Glioma, one of the most dreadful central nervous system tumors, has a high incidence rate and remains a significant challenge for treatment. However, the development of nanomedicine provides new opportunities for long-term therapy. Various obstacles, such as the blood-brain barrier permeation, hypoxia, and complex tumor microenvironment, hinder the development of novel therapeutics. Efforts have been made to explore nanoformulations to improve permeation and address these challenges. The article provides an overview of glioma classification, pathogenic factors, current therapeutic approaches, and innovative strategies, concluding with suggestions for future improvement in diagnosis and therapy.

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.
