Summary: By comparing the molecular composition and environmental significance of different soil organic matter (SOM) fractions, we found that only HA and BE fractions were successful in capturing the overall processes of soil carbon (C) dynamics. Different SOM fractions can be used complementary to each other to study the environmental and ecological effects of forest stand conversion on soil C dynamics.

Summary: The study investigated the interaction between river sediments from cold regions and typical antibiotics, focusing on the fluorescence quenching of different substances. Results showed that tetracycline addition promoted the fluorescence quenching of protein-like, marine humic acid, and humic acid-like substances in the sediment. The complex formed during the quenching reaction varied in strength depending on the type of substance, and tetracycline also affected the secondary structure of protein-like substrates in the sediment organic matter.

Summary: This study aimed to explore the feasibility of ultrafiltration (UF) and polyethylene glycol (PEG) precipitation for macroprolactin screening, as well as the incidence and clinical characteristics of Chinese patients with macroprolactinemia. The results showed a high correlation between UF and PEG precipitation, with PEG precipitation having smaller variation and substantial diagnostic consistency with gel filtration chromatography (GFC). The incidence of macroprolactinemia in Chinese patients with hyperprolactinemia (HPRL) was found to be low in this study. We recommend using PEG precipitation screening only for patients clinically suspected of having macroprolactinemia.

Summary: This study analyzed the quantitative and qualitative properties of dissolved organic matter using fluorescence spectroscopy in different sand column systems. The findings showed the presence of two fluorescent DOM fractions and a correlation between DOM, fDOM, and SUVA at 254 nm in indoor systems. In outdoor columns, while the removal of DOM and fDOM was high, there was an increase in aromaticity. Dissolved oxygen consumption was influenced by organic content in sand and not residence times. Bank filtration was found to be effective in removing biodegradable DOM under outdoor natural conditions.

Summary: In a case where a young male presented with persistently elevated TSH levels but clinically and biochemically demonstrated euthyroidism, it was found that the patient harbored macro-TSH, a rare condition where the complex binding of TSH to other plasma proteins leads to elevated plasma TSH levels while the biologically active fraction remains normal.

Summary: The nutrient-rich biogas slurry has good potential as an organic fertilizer in farmland. Different C/N ratios in biogas slurry have different effects on soil organic matter properties, and in this experiment, the biogas slurry with a C/N of 8.84 showed the most significant promotion effect on corn growth, utilization of organic matter by plants and microorganisms, and humification in the soil. These findings provide valuable insights for utilizing biogas slurry in agriculture.

Summary: Halocins are antimicrobial peptides secreted by haloarchaea, with Halocin HA4 being a heat-resistant compound with unique N-terminal sequence. It retains complete activity in the presence of various organic compounds, but its activity is reduced after treatment with certain enzymes, indicating its proteinaceous nature. Halocin HA4's cytocidal nature was demonstrated by its interaction with cell membrane and nucleic acids of target cells, suggesting potential applications in food preservation and leather industries.

Summary: Photodynamic therapy (PDT) is a promising antitumor modality that utilizes a unique combination of visible light, molecular oxygen, and a light-sensitive molecule to induce reactive oxygen species and tumor cell death. The interaction between charged chlorin photosensitizers and blood transport proteins, as well as their potential binding with biocompatible carriers, is discussed. The results show that the charge sign, number, and relative position of charged groups strongly influence the PS-protein interaction. Lipoproteins are important carriers for PS molecules in antitumor PDT, and chlorins with a single cationic group at a specific position of the macrocycle are found to be more efficient photosensitizing agents.

Summary: An instrumental neutron activation analysis method combined with Compton suppression spectrometry was developed for the simultaneous determination of Cl, Br, and I in salmon muscle and skin at nanogram levels. The extraction of organohalogens in lipids was optimized using different solvent systems, and an acetone-hexane (1:1) system was selected for its high efficiency and low contamination. The study also included the development of lipid fractionation procedures and characterization techniques using nuclear magnetic resonance and mass spectrometry. Results showed high levels of triacylglycerols in both muscle and skin.

Summary: The study investigated the different phytotoxicity of atrazine in two different soils to soybeen seedlings, and discussed the potential mechanism by examining the adsorption properties of atrazine with the soils as well as the fluorescent characteristic variation of the DOM extracted from the soils during binding with atrazine. The results suggest that atrazine exhibited different phytotoxicity to soybean seedlings in the two soils, indicating that the components of DOM in different soils may play a role in regulating the environmental behavior and phytotoxicity of organic pollutants.

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.
