The aging process has been one of the most necessary research fields in the current century, and knowing different theories of aging and the role of different genetic, epigenetic, molecular, and environmental modulating factors in increasing the knowledge of aging mechanisms and developing appropriate diagnostic, therapeutic, and preventive ways would be helpful. One of the most conserved signs of aging is epigenetic changes, including DNA methylation, histone modifications, chromatin remodeling, noncoding RNAs, and extracellular RNAs. Numerous biological processes and hallmarks are vital in aging development, but epigenomic alterations are especially notable because of their importance in gene regulation and cellular identity. The mounting evidence points to a possible interaction between age-related epigenomic alterations and other aging hallmarks, like genome instability. To extend a healthy lifespan and possibly reverse some facets of aging and aging-related diseases, it will be crucial to comprehend global and locus-specific epigenomic modifications and recognize corresponding regulators of health and longevity. In the current study, we will aim to discuss the role of epigenomic mechanisms in aging and the most recent developments in epigenetic diagnostic biomarkers, which have the potential to focus efforts on reversing the destructive signs of aging and extending the lifespan.

Objective: Unidentified sex differences in old-age cognition may emerge in psychometric networks, which look beyond mean scores into the unique cognitive structure of males and females. Accordingly, this study aims to examine cognition in well-functioning older males and females with psychometric network analysis.
Methods: The current cohort (N = 2,802) of community-dwelling adults (≥65 years) was derived from the Advanced Cognitive Training for Independent and Vital Elderly study.

Background And Aim: The relationship between socio-economic inequalities (SEIs) and early life malnutrition with muscle health remains unclear. This study aims to examine the effects of SEIs and early life exposure to famine on relative hand grip strength (rHGS).
Methods And Results: We analyzed data of 37,008 individuals from the China National Health Survey.

Objectives: This study aimed to assess the potential of experimental dental resins containing ZnO nanoparticles (ZnO-NPs) for antimicrobial photodynamic therapy (aPDT) as a functional tool for the modulation of cariogenic biofilm in long-term.
Methods: Minimum inhibitory and bactericidal concentrations (MIC/MBC) of ZnO-NPs against Streptococcus mutans were initially determined under different energy densities of blue LED irradiation (0.00, 1.

Fibroblast-like synoviocytes (FLS) are key cells promoting cartilage damage and bone loss in rheumatoid arthritis (RA). They are activated to assume an invasive and migratory phenotype. While mechanisms of FLS activation are unknown, evidence suggests that pre-damaged extracellular matrix (ECM) of the cartilage can trigger FLS activation.

People with HIV (PWH) are living longer and experiencing a greater burden of morbidity from non-AIDS-defining conditions. Chronically treated HIV disease is associated with ongoing systemic inflammation that contributes to the development of chronic conditions (eg, cardiovascular disease) and geriatric syndromes (eg, frailty). Apart from HIV disease, a progressive increase in systemic inflammation is a characteristic feature of biologic aging, a process described as "inflammaging.
