Summary: Inhaled particles and gases can harm health by promoting chronic inflammation in the body. This study investigated the relationship between outdoor air pollution and inflammation by race and ethnicity, socioeconomic status, and lifestyle risk factors. The results showed that particulate matter (PM) and other markers of traffic-related air pollution were associated with circulating levels of C-reactive protein (CRP), a biomarker of systemic inflammation.

Summary: This study examines methods for quantifying individual exposure to traffic-related air pollutants and finds that LUR estimates are correlated with summer personal exposure, while winter personal exposure is more related to the length of major roadways. This suggests potential exposure misclassification when using traditional proxy methods, especially for children during key growth and developmental periods.

Summary: This study utilized land use regressions to generate high-resolution nitrogen dioxide and ozone exposure surfaces for the Greater Beirut Area in Lebanon. It found that traffic emissions and a fossil-fuel power plant were the main contributors to NO2 and NOx levels, while serving as sinks for O-3 concentrations. The results indicated that around 99% of the population in the GBA were exposed to NO2 levels exceeding the WHO standard.

Summary: Exposure to traffic-related air pollutants, such as NO2 and O3, can have detrimental health effects and is a major global public health issue. Exercising in polluted environments may be harmful to health and impede exercise training adaptations. This study aimed to investigate the effects of physical activity and O3 exposure on redox status, inflammatory markers, stress response, and pulmonary toxicity in young, healthy individuals. The results showed that physical activity was associated with higher O3 exposure, but not with age or markers of body composition. Individuals with high physical fitness and lower O3 exposure had better antioxidant defense, lower inflammation, and reduced pulmonary toxicity.

Summary: This study presents a method for obtaining high-resolution spatiotemporal distributions of population and their exposure to traffic-related PM2.5 in Guangzhou, China. The results indicate population density hotspots and reveal that low-income individuals and rural-urban migrants have higher exposure to PM2.5 compared to commuters in enclosed cabins. These findings emphasize the urgent need to mitigate the negative impacts of traffic-related PM2.5 on public health.

Summary: This study investigated the physiological and metabolic effects of polystyrene (PS) and aged polystyrene (A-PS) microplastics on Dunaliella salina. It was found that they inhibited the growth of microalgae but promoted pigment synthesis. Oxidative stress analysis showed that PS and A-PS caused oxidative damage to algal cells. Metabolomics analysis showed that PS and A-PS significantly increased different metabolites.

Summary: This study investigates the performance of T-joints in the jacket foundation of offshore wind turbines under impact loading by means of experimental and simulation analysis. The deformation pattern and dynamic response of one hollow T-joint and eight concrete-filled double steel tubular T-joints (CFDST T-joints) are explored through a pendulum testing machine. The experimental results indicate that the local indentation dominates in the deformation process of hollow T-joint while the failure mode of CFDST T-joint will be commonly the global bending. The impact force-displacement curves corresponding to different parameters have similar tendencies and each curve can be divided into four stages. Increasing the impact velocity and axial compression ratio can reduce impact resistance. Meanwhile, increasing outer tube thickness and changing hollow rate exert a remarkable effect on the dynamic performance. Finite element models are then proposed to validate the experimental results and investigate the energy dissipation mechanism of T-joints under impact loading. The plastic deformation of the outer tube is the main energy dissipation mechanism for CFDST T-joints. In general, the investigation in this study offers a reliable basis for the study of impact failure mechanism for CFDST T-joint.

Summary: This study found that sustained exposure to higher concentrations of air pollutants is associated with increased prevalence of metabolic syndrome (MetS) and its components. For every 10μg/m³ increase in air pollutant concentrations, the risk of MetS increased. The study also identified that age may significantly modify the association between air pollution and MetS.

Summary: This study investigates the phenotypic and molecular adaptations to exercise in young and old mice, and reveals that exercise protects tissues from infectious injury, suppresses inflammaging in aged individuals, and improves the central nervous system and systemic vasculature. The study also uncovers the role of the core circadian clock protein BMAL1 in delaying senescence and promoting recovery from infectious damage, resembling the beneficial effects of exercise. These findings highlight the significance of exercise in rejuvenating the circadian clock network and pave the way for further exploration of the interaction between exercise, aging, and immune challenges in the whole organism.

Summary: A new magnetic adsorbent MnFe2O4/D201 was prepared, which exhibited deep-treatment ability and high selectivity adsorption for As(V). The adsorption process of As(V) primarily involved chemical bonding. The maximum adsorption capacity of MnFe2O4/D201 for As(V) reached 35.8 mg/g at pH 3. MnFe2O4/D201 also showed higher selectivity adsorption against Cl-, NO3-, SO42-, and PO43-.

Summary: A generic approach for designing plasmonic lenses to generate predesigned vector surface plasmon polaritons (SPPs) vortices with high efficiencies is established. The devices, constructed with tailored meta-atoms, can convert normally incident circularly polarized light into desired vector SPP vortices due to phase and polarization matching. Experimental demonstrations of directional SPP conversion (coupling efficiency: 35%; utilization efficiency: 98%) and enhanced efficiency in generating vector SPP vortex pave the way for on-chip plasmonic devices to efficiently utilize SPPs with minimal footprints.

Summary: This study establishes a new scheme for realizing highly miniaturized couplers to efficiently excite on-chip photonic devices. By utilizing both resonant and Pancharatnam-Berry mechanisms, the meta-device can couple circularly polarized light to a surface plasmon and focus it onto a target on-chip device. Experimental results demonstrate the high efficiency of this scheme in exciting on-chip waveguides and dual-waveguide systems.

Summary: In this study, a simulated photoelectron system was used to investigate the effects of semiconducting mineral photoelectrons on the microbial community and sulfate reduction. The results showed that photoelectrons had significant impacts on microbial community diversity and sulfate reduction rate, and promoted the enrichment of sulfate-reducing bacteria. This process has important implications for carbon and sulfur element cycling as well as the formation of dolomite.

Summary: This study proposes a risk assessment method for lift-jacking accidents, using a combination of fuzzy fault tree analysis (FFTA) and failure mode and effects analysis (FMEA). Qualitative analysis of the fault tree is used to identify risk factors, and a hybrid approach is applied to quantify the probability of each bottom event. The FFTA-FMEA model aggregates expert assessments to effectively eliminate ambiguity and uncertainty, and facilitates the quantification and identification of medium to high-risk factors in lift-jacking accidents.

Summary: In this study, an RA knowledge graph based on Chinese electronic medical records (CEMRs) was established, solving the issue of requiring large amounts of manually labeled data for knowledge extraction from CEMRs. The proposed method used a pretrained language model (MC-BERT) combined with a deep neural network to automatically extract knowledge and construct a visualized RA knowledge graph. The evaluation results showed that the method achieved better performance in entity recognition and relation extraction tasks.
