The mud crab, Scylla paramamosain, is an economically-important crab in China. Air exposure is an important environmental stressor during mud crab culture and transportation. Adaptive mechanisms responding to air exposure in mud crabs are still poorly understood. In this study, mud crabs were exposed to air for 120 h. Air exposure decreased total hemocyte counts, led to cytological damage, and caused high mortality. Transcriptomic analysis was conducted at 0, 6 and 96 h after air exposure. A total of 3530 differentially expressed genes (DEGs) were identified. DEGs were mainly involved in the oxidative stress response, metabolism, cellular processes, signal transduction, and immune functions. Transcriptomic analysis also revealed that genes of glycolysis and of the tricarboxylic acid cycle were key factors in regulating the mud crab adaptation to air exposure.

Objective: The study investigated the effects of air pollutants on the incidence of acute angle-closure glaucoma (AACG) in Hefei, China.Methods: A combination of generalized additive models (GAM) and distributed lag non-linear models (DLNM) was used to explore the relationship between air pollutants and the incidence of AACG.Results: Exposure-response curves showed that exposure to PM2.

Background: Coccidioidomycosis, caused by inhalation of spp. spores, is an emerging infectious disease that is increasing in incidence throughout the southwestern US. The pathogen is soil-dwelling, and spore dispersal and human exposure are thought to co-occur with airborne mineral dust exposures, yet fundamental exposure-response relationships have not been conclusively estimated.

Background: Ambient air pollution, detrimental built and social environments, social isolation (SI), low socioeconomic status (SES), and rural (versus urban) residence have been associated with cognitive decline and risk of Alzheimer's disease and related dementias (ADRD). Research is needed to investigate the influence of ambient air pollution and built and social environments on SI and cognitive decline among rural, disadvantaged, ethnic minority communities. To address this gap, this cohort study will recruit an ethnoracially diverse, rural Florida sample in geographic proximity to seasonal agricultural burning.

A self-opening transfer shuttle has been designed and fabricated for the transfer of air-sensitive samples to scanning electron microscopy (SEM). Delayed push out of an airtight sample cabin sealed inside the shuttle allows the protection of the sample from air exposure during the pumping of SEM chamber. A compressed spring is employed to automatically drive the push out of the cabin.

Purpose Of Review: Indoor air pollution is likely to be elevated in multi-family housing and to contribute to health disparities, but limited studies to date have systematically considered the empirical evidence for exposure differentials between multi-family and single-family housing. Our goal is to separately examine the drivers of residential indoor air pollution, including outdoor air pollution, ventilation and filtration, indoor sources, and occupant activity patterns, using secondhand smoke as a case study to examine the behavioral dimensions of indoor environmental interventions.
Recent Findings: Within studies published from 2018 to 2023, multi-family homes have higher average outdoor air pollution than single-family homes given their more frequent presence in urban and near-roadway settings.
