Evidence has shown that both smoking and periodontitis were linked to cognitive impairment. This study examines whether mediates the effects of status on function in older adults. Using data from National Health Nutrition Examination Survey (NHANES) 2011–2014, included 1728 participants who have smoking, serum cotinine, periodontal examination, function. Mediation analysis was performed test extent mediated associations between function, adjusted for sociodemographic basic health factors. Compared never-smokers, daily smokers exhibited significantly worse global with mediating this effect (effect= -0.16; 95% CI= -0.29, -0.05). Similarly, association cotinine levels total sample -0.02; -0.03, -0.00). Periodontitis impact The findings highlight potential roles maintaining oral cessation mitigating decline.

Abstract Interferon‐induced transmembrane protein 3 (IFITM3) is implicated in the pathogenesis of Alzheimer's Disease (AD) by regulating γ‐secretase activity and subsequent amyloid β (Aβ) generation. However, regulation IFITM3 gene expression underlying mechanisms remain exclusive. In this study, we aimed to investigate its role amyloidogenesis. The functional active promoter was identified within 1047 bp 5′‐flanking regions luciferase assays. Through chromatin immunoprecipitation (ChIP) electrophoretic mobility shift assay (EMSA), successfully a specific Krüppel‐like factor 9 (KLF9) binding site region. Moreover, KLF9 overexpression significantly upregulates vitro vivo, which promotes Aβ generation hippocampus mice. Consistently, reduced results notable decrease production. Together, demonstrate that plays critical It highly suggests inhibiting KLF9‐mediated may have therapeutic potential for AD reducing
