The goal of this review is to highlight the role second-hand smoke (SHS) or environmental tobacco (ETS) and e-cigarette (EC) vapors on brain integrity function during development adulthood, including how it relates increasing risk for age-related neurodegenerative disorders. A systematic literature effect SHS ETS revealed a total 284 372 publications 312 publications, respectively. After taking into account duplicate focused policy, surveys other organs than brain, there are limited studies effects SHS, EC structure function. In review, we examine major constituents in their health, mechanisms by which alters function, behavioral cognitive performance. We hope that will encourage investigators explore further short-as well long-term vapor exposure developing adult better understand its neurodevelopmental disorders diseases ultimately develop therapeutic modalities reduce even prevent short- detrimental health.

Abstract The rising global temperatures due to climate change have a profound impact on health. Heat is associated with many physical and mental health conditions. of heat could be exacerbated in polluted areas the combined pollutants stress. Polycyclic aromatic hydrocarbons (PAHs) are among environmental public significance. Exposure PAHs has adverse effects these worse oil-impacted communities increased PAH exposure degradation. increases volatilisation PAHs, mobility availability formation toxic derivatives, possible wildfire incidents which introduce more into environment. This human through various pathways, addition stress, thereby worsening challenges. anticipated decrease levels reduced emissions offset by temperatures, promote mobilisation existing PAHs. Therefore, this review highlighted risks amid especially communities. mechanisms increase were also highlighted. Possible pollution prevention, mitigation, intervention approaches suggested. Rapid oil spill response, remediation, ecosystem restoration, biomonitoring, environmental, agro products monitoring help mitigate exposure. Additionally, introduction green education, assessment for every project, investment sustainable technologies companies. Overall, creates awareness neglected draws attention researchers, funders, policymakers, society as we navigate challenges change. Graphical

Traffic-related ultrafine particles (UFPs) are an emerging health concern affecting the brain and increasing risk of Alzheimer's disease (AD). PI3K/AKT signaling is known to contribute neuronal survival be altered in AD. The nasal olfactory mucosa (OM) a sensory tissue exposed directly ambient air, starting point for neural circuits towards brain. Evidence air pollution-induced transcriptional regulation via microRNAs (miRNA) DNA methylation (DNAmet) accumulating pollutant-mediated disturbances have been reported. By utilizing highly translational human-based vitro model OM, we aimed investigate possible gene regulatory mechanisms induced by UFPs, compare responses between cognitively healthy individuals with miRNA expression was analyzed using next-generation sequencing (NGS) chip-based analysis performed detect differentially methylated loci (DML). These data were combined previously published transcriptomics (mRNA) construct mRNA-miRNA-DNAmet-integrative network. Protein level changes studied immunoassays. We observed UFP-induced reductions viability increases oxidative stress damage without eminent cell death. Integrative network revealed multiple connections miRNAs expressed genes pathway, effects most prominent AD cells. Similarly, cells DML identified transcription factor apoptosis genes, downstream signaling. Conclusively, traffic-related UFPs influence modulate OM survival, existing pathology resulting heightened vulnerability UFP effects.
