Abstract Background Cognitive function measured by digital clock drawing test (dCDT) has drawn attention for their precision, automation, and reproductivity. However, the relationship between cognitive metrics biological aging is lacking. Methods We conducted association analyses dCDT quantified five DNA methylation (DNAm) age (Horvath, Hannum, GrimAge, PhenoAge, DunedinPACE) in Framingham Heart Study (FHS). linear regression to investigate functions (global four sub-domain functions) DNAm acceleration, adjusting covariates. used a false discovery rate (FDR) < 0.05 significance. Results Among 1,798 FHS participants (mean 65±13, 53% women), we found that lower total score associated with acceleration. Larger magnitudes of associations were observed older (≥ 65 years).

The acceleration of aging is a risk factor for numerous diseases, and diet has been identified as an especially effective anti-aging method. Currently, research on the relationship between dietary nutrient intake accelerated remains limited, with existing studies focusing small number individual nutrients. Comprehensive single mixed effects nutrients not conducted. This study aimed to comprehensively explore intakes, both singly in combination, aging. Data this were extracted from 2015–2018 National Health Nutrition Examination Surveys (NHANES). was measured by phenotypic age acceleration. Linear regression (linear), restricted cubic spline (RCS) (nonlinear), weighted quantile sum (WQS) (mixed effect) models used association A total 4692 participants aged ≥ 20 included study. In fully adjusted models, intakes 16 negatively associated (protein, vitamin E, A, beta-carotene, B1, B2, B6, K, phosphorus, magnesium, iron, zinc, copper, potassium, fiber, alcohol). Intakes sugars, C, caffeine, alcohol showed significant nonlinear associations Additionally, Single well may mitigate Moderately increasing specific maintaining balance be key strategies prevent

Abstract The pathology of cardiovascular aging is complex, involving mitochondrial dysfunction, oxidative and nitrative stress, DNA injury, impaired lipid metabolism, cell death, senescence, chronic inflammation. These processes lead to remodeling structural changes in the system, resulting a progressive decline reserve capacity health, an increased risk diseases mortality. Excessive alcohol consumption exacerbates these risks by promoting hypertension, stroke, arrhythmias, coronary artery disease, cardiomyopathy, sudden cardiac yet effects on remain unclear. Herein, we explored impact 6-month 5% Lieber-DeCarli diet young (3 months old) (24–26 Fisher F344BNF1 rats. We assessed detailed hemodynamics, function, oxidative/nitrative inflammation, myocardial fibrosis using pressure–volume isolated vascular rings, various histological, biochemical, molecular biology methods. Alcohol both rats disrupted cholesterol triglyceride leading systolic contractile function. In rats, further exacerbated diastolic dysfunction fibrosis. also apoptosis, senescence vasculature, contributing endothelial total peripheral resistance. Additionally, aging-related ventriculo-arterial uncoupling diminished efficiency, reducing capacity. conclusion, promotes diminishes already associated with aging.

The reliability of the associations acceleration epigenetic aging (EA) indices with clinical phenotypes other than for smoking and drinking is poorly understood. Furthermore, majority phenotyping studies have been conducted using data from subjects European ancestry. In order to address these limitations, we clinical, physiologic, assessments a cohort 278 middle-aged African American adults analyzed recently described principal-components-trained version GrimAge (i.e., PC-GrimAge) DunedinPACE (PACE) index regression analyses. We found that 74% PC-GrimAge accelerated could be predicted by simple baseline model consisting age, sex, methylation-sensitive digital PCR (MSdPCR) drinking. addition serological, demographic, medical history variables or PACE values did not meaningfully improve prediction, although some significantly fit. contrast, mapping cardiometabolic syndrome independently contribute prediction beyond model. were correlated (r = 0.2), little overlap in variance explained conveyed results suggest EA may differ information they provide significant limitations as screening tools guide patient care.

Along with the ageing of society, absolute prevalence age-related diseases is expected to rise, leading a substantial burden on healthcare systems and society. Thus, there an urgent need promote healthy ageing. As opposed chronological age, biological age was introduced accurately represent process, as it considers physiological deterioration that linked morbidity mortality risk. Furthermore, responds various factors, including nutritional which have potential mitigate risk diseases. result, promising biomarker known epigenetic clock has emerged suitable measure investigate direct relations between factors ageing, thereby identifying intervention targets improve In this study, we analysed data from 3,969 postmenopausal women Women's Health Initiative identify nutrients are associated rate by using accurate called PhenoAge clock. We used Copula Graphical Models, data-driven exploratory analysis tool, relationships nutrient intake age-acceleration, while correcting for every variable in dataset. revealed increased dietary intakes coumestrol, beta-carotene arachidic acid were decelerated contrast, added sugar, gondoic acid, behenic arachidonic vitamin A ash accelerated women. Our study discovered revealing areas follow-up studies determine magnitude causality our estimated diet-epigenetic relationships.

Although detrimental changes in mitochondrial morphology and function are widely described symptoms of fetal alcohol exposure, no studies have followed these deficits into adult life or determined if they predispose individuals with spectrum disorders (FASDs) to accelerated biological aging. Here, we used a multiplex preclinical mouse model compare markers cellular senescence age-related outcomes induced by maternal, paternal, dual-parental exposures. We find that even middle (postnatal day 300), the offspring alcohol-exposed parents exhibited significant increases stress-induced premature brain liver, including an upregulation cell cycle inhibitory proteins increased senescence-associated β-galactosidase activity. Strikingly, male offspring, observe interaction between maternal paternal use, histological indicators liver disease exceeding those either use alone. Our indicate chronic parental causes enduring dysfunction resulting reduced NAD+/NAHD ratio altered expression NAD+-dependent deacetylases SIRT1 SIRT3. These observations suggest some aspects FASDs may be linked aging due programmed regulation bioenergetics.
