This multicenter study is the first age-restricted (≥ 60 years) subgroup analysis of the Brazilian PLHIV Stigma Index 2.0. The present secondary analysis yielded a sample of 138 older adults (M age = 64.3 years, SD = 4.1; 52.9% male; 57.2% Black or Brown). Path analysis with 5000-resample bootstrapping and full-information maximum likelihood estimation confirmed a statistically significant indirect effect of general stigma on depression mediated by internalized stigma (indirect effect = 0.087, 95% CI [0.037, 0.173], <i>p</i> = 0.009), with no significant direct pathway (c' = 0.058, <i>p</i> = 0.324).

These findings support a mechanistic model in which internalized stigma mediates the effect of social discrimination on both depressive and anxious symptomatology, and resilience acts as an upstream protective factor.

In this study, we used D-galactose (D-gal) to establish a senescence model in C2C12 cells. Our results demonstrate that aging C2C12 cells displayed a significant impairment in differentiation capacity, an effect that was ameliorated by NMN treatment, as indicated by an increase in myotube formation and elevated myosin heavy chain (MHC) expression. NMN significantly decreased reactive oxygen species (ROS) levels in both aged C2C12 myoblasts and myotubes.

Immunofluorescence staining revealed that the expressions of p53 and interleukin-1β (IL-1β) were significantly upregulated in aged C2C12 myotubes, while NMN treatment significantly attenuated this elevation.
