Summary: By investigating Cr-doped zinc gallate ZnGa2O4 nanoparticles with near-infrared emission in colloidal solutions of different pH levels under X-ray excitation, this study aims to develop pH-sensitive luminescent materials for diagnosing disease and imaging-guided therapy using high-energy radiation. The results show that the colloidal nanoparticles exhibit pH-dependent radioluminescence in a linear relationship, with a 4.6-fold enhancement observed at pH 4 compared with neutral solution. This finding provides a strategy for developing new biomaterials for potential pH-sensitive imaging and imaging-guided therapy.

Summary: In this study, pH-sensitive gelatin-based films were developed using response surface methodology with red cabbage extract and zinc oxide nanoparticles. Oxidized sucrose (OS) served as a cross-linker to compensate for gelatin solubility, leading to decreased solubility in films with higher OS levels. The combination of ZnONPs and OS enhanced antioxidant activity, with the optimum treatment including 0.043% ZnONPs and 11.45% OS to improve film strength and decrease flexibility. Antimicrobial activity was higher against Staphylococcus aureus than Escherichia coli, and the color of the optimum film changed from reddish-purple to blue-green between pH 3-12, providing innovative and intelligent packaging material.

Summary: The co-occurrence of nanoplastics with metal oxide nanoparticles and polycyclic aromatic hydrocarbons has been widely studied, yet little is known about their interactions and combined toxic effects. This research found that increasing the concentration of metal oxide nanoparticles led to aggregation of nanoplastics, while polycyclic aromatic hydrocarbons had no major impact on nanoplastic stability. The size of the nanoplastics played a role in genotoxicity, with smaller nanoplastics showing higher levels of DNA damage.

Summary: This study proposes the use of iron-doped zinc oxide nanoparticles (Fe:ZnO NPs) with theranostic capabilities and the synergistic effect of shock waves for the treatment of pancreatic ductal adenocarcinoma. The Fe:ZnO NPs exhibit superior magnetic properties, colloidal stability, and cytocompatibility compared to undoped ZnO NPs. The combination of Fe:ZnO NPs and shock waves induces enhanced cell death through mechanisms such as NP dissolution, cell membrane disruption or permeation. This study provides a promising concept for future applications in the treatment of deep-seated tumors like pancreatic cancer.

Summary: Our study investigated the chemical characteristics and health risks of PM2.5 in Taipei, Taiwan from 2019-2020. The major sources of PAHs were vehicle emissions and coal combustion, with higher levels of PAHs in local pollution compared to long range transport. Daytime PM2.5 concentrations were higher than nighttime concentrations, reflecting high traffic emissions and anthropogenic aerosols during the day. The City Tunnel showed higher PM2.5 concentrations during the daytime due to heavy traffic, and long-range transport and industrial emissions contributed to higher values in coastal areas of Inner Mongolia and Mainland China.

Summary: Residents and workers exposed to high levels of CO2 in buildings may experience negative health effects. This study examined the impact of plants on indoor CO2 reduction and health symptoms relief. The results showed that participants in the office room with plants had lower levels of drowsiness and systolic blood pressure compared to those in the room without plants. Additionally, there was a correlation between increased indoor CO2 levels and drowsiness.

Summary: In this study, we investigated the relationship between Hippo signaling pathway components and the development of emphysema in air pollution-exposed ageing rats. The results showed that air pollution led to inflammation in the lungs and increased airway thickness, and the Hippo signaling pathway was dysregulated. The study also revealed the potential risk of emphysema development in smokers and COPD patients.

Summary: This study presents a mathematical formulation of the relationship between PM2.5 and satellite aerosol optical depth (AOD). The study shows that the slope of the relationship depends on aerosol type, scattering enhancement factor f(RH), and boundary layer height, while the intercept is influenced by the vertical aerosol profile. A new aerosol index, NGAI, is used for classifying aerosol subtypes, and the combination of AOD difference at different wavelengths helps distinguish previously indistinguishable aerosol types. The study also proposes a method to calculate the scattering enhancement factor f(RH) and demonstrates its feasibility. The findings suggest that the value of f(RH) for urban-industrial aerosols is around 2.6 when RH exceeds 80%, while for biomass burning aerosols, it does not exceed 1.5. The study provides a new approach to improve the AOD-PM2.5 relationship by exploiting differences in aerosol hygroscopicity.

Summary: This study used diffusion tensor imaging (DTI) to investigate the effects of long-term exposure to PM2.5 on Parkinson's disease (PD) in the elderly. The results showed motor impairment and disrupted white matter integrity in aged rats exposed to PM2.5. Inflammatory demyelination of multiple fiber tracts was observed as well. These findings suggest that DTI-based biomarkers may have the potential for early detection of PD progression in the elderly.
