Summary: In this study, it was found that PM2.5 aggravated airway remodeling in chronic asthma and exacerbated asthma manifestation in acute asthma. Low BMAL1 expression was found to be crucial for airway remodeling in PM2.5-challenged asthmatic mice. BMAL1 was found to bind and promote ubiquitination of p53, resulting in increased p53 levels and autophagy in bronchial epithelial cells. Autophagy in bronchial epithelial cells mediated collagen-I synthesis and airway remodeling in asthma. Thus, BMAL1/p53-mediated bronchial epithelial cell autophagy contributes to PM2.5-aggravated asthma.

Summary: This study explored the toxicological mechanisms of PM2.5-induced lung dysfunction by investigating the expression and interaction of circ_0038467 and miR-138-1-3p in human bronchial epithelial cells. Results showed that PM2.5 treatment led to changes in circ_0038467 and miR-138-1-3p expression, affecting cell proliferation, apoptosis, and inflammatory responses. Circ_0038467 modulated PM2.5-induced cell injury through regulating miR-138-1-3p expression, suggesting a potential therapeutic target for air pollution-related lung dysfunction in the future.

Summary: The impact of PM2.5 on epithelial cells is a crucial process leading to lung pathological changes and diseases. This research evaluates the effects of different interaction models of PM2.5 on epithelial cell damage through a direct stimulation model using human bronchial epithelial cell line (BEAS-2B) and an indirect stimulation model using a co-culture of macrophages and epithelial cells. The results indicate that the direct stimulation model inhibits the viability of BEAS-2B cells, while the indirect stimulation model strengthens inflammation response and induces epithelial-mesenchymal transition (EMT) in lower concentrations of PM2.5.

Summary: PM2.5 induces lung injury through increased ROS generation and inflammation. In contrast, treatment with exogenous 8-OHdG decreases RAC1 activity and eventually decreases NOX and ROS generation. In this study, it was found that 8-OHdG attenuated PM2.5-induced ROS generation and NLRP3 inflammasome activation in respiratory cells by inhibiting RAC1 activity and NOX1 expression.

Summary: This study investigated the role of exosomes from bronchial epithelial cells in promoting lung cancer metastasis induced by PM2.5. The results showed that exosomes derived from PM2.5-treated bronchial epithelial cells promoted the migration, invasion, and epithelial-to-mesenchymal transition of lung cancer cells through activation of c-Jun N-terminal kinase. These findings provide new insights into the cancer-promoting mechanisms of environmental pollutants.

Summary: The uptake of acetic acid on natural Gobi dust was investigated under different levels of relative humidity. Acetic acid was found to compete with water molecules for adsorption sites on Gobi dust, and its uptake decreased with increasing humidity. Interestingly, at high humidity levels, the uptake of acetic acid led to the formation of oxygenated volatile organic compounds. This study highlights the reactivity of acetic acid on natural mineral dust, and its potential contribution to atmospheric processes.

Summary: Ferroptosis, an iron-dependent regulated cell death triggered by high lipid peroxide levels, has been implicated in neurodegenerative diseases like Parkinson's disease (PD). The exact pathways and conditions leading to the death of dopaminergic neurons in PD remain unknown. This study shows that altering the PUFA composition in dopaminergic neuron membranes can determine susceptibility to ferroptosis, and cotreatment with iron promotes lipid peroxidation and cell death. Inhibition of specific enzymes involved in the lipid peroxidation pathway could be potential targets for neuroprotective strategies in PD.

Summary: The wide range of sources and complex transformation processes of aerosol particles result in strong spatial and temporal variability in their physical, chemical, and optical properties. Accurate representation of these properties is crucial for assessing their impacts, particularly on climate. This study investigates aerosol optical properties and their correlation with fine particle chemical composition in Northern France, using a multi-annual in situ dataset. The findings reveal the significant contributions of ammonium nitrate and organics, highlighting the need for site-specific values to accurately assess the impact of different aerosol species on extinction. The study emphasizes the importance of combined aerosol chemical and physical observations to better estimate their role in climate change and reduce uncertainties in future scenarios based on mitigation strategies.

Summary: This study aims to utilize machine learning to predict the retention time and collision cross-section of metabolites in an open-access database, in order to expedite the interpretation of metabolomic results. Through the use of liquid chromatography coupled with high-resolution mass spectrometry, standards of metabolites were tested and machine learning models were employed to generate predicted values for collision cross-section and retention time. The models demonstrated high reliability, with R-2 scores of 0.938 and 0.898 for collision cross-section and retention time, respectively.

Summary: Studies have shown that exposure to organic pollutants may alter sex steroid hormone levels in animals and humans. However, research on the mixture effects of these pollutants is limited, and the focus has been mainly on persistent organic pollutants. In this study, hair analysis was used to evaluate the relationship between multiclass organic pollutants and sex steroid hormones in healthy Chinese women. The results showed that each hormone was associated with a mixture of at least 10 examined pollutants.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
