Hybrid model of care for older persons for improvement of frailty index-a community-based interventional study in an urban setting
CONCLUSION: Frailty could be reversed with appropriate interventions designed on the pillars of self-efficacy, and social interdependence among family members. The hybrid model of care delineates the role of caregivers, who reinforce the old persons to follow prescribed interventions.
Effect of leisure activity on frailty trajectories among Chinese older adults: a 16-year longitudinal study
CONCLUSIONS: This study suggests that older adults should be encouraged to increase both the amount and variety of their leisure activities. Physically stimulating activities should be considered the primary choice, followed by socially and cognitively stimulating activities.
Factors associated with fall risk increasing drug use in older black and white men and women: the Health ABC Study
CONCLUSIONS: Risk factors for FRID use in older adults differ slightly by STEADI-R(x) and SNBHW FRIDs definition, but are largely similar.
Dietary factors and DNA methylation-based markers of ageing in 5310 middle-aged and older Australian adults
The role of nutrition in healthy ageing is acknowledged but details of optimal dietary composition are still uncertain. We aimed to investigate the cross-sectional associations between dietary exposures, including macronutrient composition, food groups, specific foods, and overall diet quality, with methylation-based markers of ageing. Blood DNA methylation data from 5310 participants (mean age 59 years) in the Melbourne Collaborative Cohort Study were used to calculate five methylation-based...
Resistance training suppresses accumulation of senescent fibro-adipogenic progenitors and senescence-associated secretory phenotype in aging rat skeletal muscle
Accumulation of senescent cells in tissues contributes to multiple aging-related pathologies. Senescent fibro-adipogenic progenitors (FAPs) contribute to aging-related muscle atrophy. Resistance training can help to maintain skeletal muscle mass, improve mobility, and reduce certain health risks commonly associated with aging. We investigated, using rat model, the impact of resistance training on FAPs in aging skeletal muscle, which remains unclear. Twenty-two-month-old female rats were divided...
Molecular and physiological mechanisms of aging are distinct in the cardiac right and left ventricles
Aging is the primary risk factor for heart disease, the leading global cause of death. Right ventricular (RV) function predicts survival in several age-related clinical contexts, yet no therapies directly improve RV function, in large part due to a poor mechanistic understanding of RV aging and how it is distinct from the widely studied left ventricle (LV). To address this gap, we comprehensively quantified RV functional and morphological remodeling with age. We further aimed to identify...
E5 treatment showing improved health-span and lifespan in old Sprague Dawley rats
Aging and, in particular, the emergence of age-related disorders is associated with tissue dysfunction and macromolecular damage, some of which can be attributable to accumulated oxidative damage. In the current study, we determine the potential of 'plasma-derived fraction (E5)' for cellular rejuvenation and extending the lifespan of Sprague Dawley (SD) rats. This is a unique study wherein we have used 24-month-old rats and monitored them until the end of their lifespan with and without E5...
Activation of parkin by a molecular glue
Mutations in parkin and PINK1 cause early-onset Parkinson's disease (EOPD). The ubiquitin ligase parkin is recruited to damaged mitochondria and activated by PINK1, a kinase that phosphorylates ubiquitin and the ubiquitin-like domain of parkin. Activated phospho-parkin then ubiquitinates mitochondrial proteins to target the damaged organelle for degradation. Here, we present the mechanism of activation of a new class of small molecule allosteric modulators that enhance parkin activity. The...
