Aging & Longevity

Age-related strength loss may reflect morphological and neural adaptations that differ between muscles. However, it is unclear how ageing affects motor unit (MU) discharge rate modulation and estimates of persistent inward currents (PICs) across contraction levels. Thirty young (24 ± 4 years) and thirty older adults (73 ± 4 years) underwent magnetic resonance imaging and performed unilateral isometric dorsiflexion and knee extension contractions. Individual MU spike trains were identified from...

CONCLUSION: Barriers and facilitators should be addressed in policies to promote greater involvement of geriatricians in research and research consortia.

Assessment of biological aging using proteomic clocks may enhance risk prediction and elucidate the molecular links between aging and chronic diseases. Here, among 17,473 participants of the European Prospective Investigation into Cancer and Nutrition, we examined associations of plasma SomaScan-based proteomic clocks, including organ-specific clocks, with risk factors, 24 incident chronic diseases and all-cause mortality, over up to 28 years of follow-up. Replication was conducted in the...

Mitochondria play central roles in cellular metabolism and in key processes such as inflammation, stress response, cell death and signalling. Mitochondrial quality control (MQC) mechanisms continuously monitor organelle integrity and function, and repair or eliminate damaged mitochondria to replace them with newly formed, healthy organelles. MQC is particularly important under metabolic or environmental stress conditions. Failure of MQC paves the way to chronic diseases, such as diabetes,...

CONCLUSION: This study offers an empirically grounded, contextually situated understanding of well-being among older adults in an urban Indonesian setting, extending existing frameworks by foregrounding lived experience and relational interdependence.

CONCLUSIONS: Respondents demonstrated positive attitudes towards their own ageing in the domains of physical change and psychological growth, whereas more negative attitudes were observed in the psychosocial loss domain. Loneliness and depressive symptoms were significantly associated with a more negative self-perception of ageing among older adults. A more negative self-perception of ageing was also more frequently observed among respondents with a poorly developed social network, poorer...

CONCLUSION: Adults aged 65 and above in this study demonstrated a moderate level of resilience and lower well-being scores. Higher resilience scores were significantly correlated with increased subjective well-being. These results suggest that resilience acts as a vital internal resource that relates to mental health outcomes in the aging population, highlighting the potential for interventions focused on enhancing psychological strengths.

CONCLUSIONS: IAS is a biologically informed, geriatric-oriented index of IMV that integrates aging-related immune remodeling with dynamic inflammatory responses in older adults with AECOPD. Rather than serving as a definitive measure of fixed immune-aging burden or as a dedicated infection classification tool, IAS provides a quantitative framework for biologically relevant immune-inflammatory vulnerability stratification and short-term prognostic assessment. Further prospective multicenter...

Wildfire smoke poses a growing global health risk, largely from fine particulate matter (PM(2.5)) emissions. Prescribed fires, which are critical for maintaining resilient forests in many locations, can also reduce wildfire emissions in treated areas that later burn. However, prescribed fires also produce smoke, creating a tradeoff in their net impact on PM(2.5) emissions. We develop a mathematical framework showing that, under most current conditions globally, prescribed fire emissions are...

INTRODUCTION: MicroRNAs (miRNAs) are promising biomarkers for the diagnosis and prognosis of neurodegenerative diseases. Over the past few years, miR-34a-5p and miR-126-3p have become some of the most characterized miRNA, the former being associated with cellular senescence and apoptosis and the latter with the maintenance of vascular endothelial function. The present study aimed to evaluate diagnostic performance of miR-34a-5p and miR-126-3p for cognitive dysfunction in CSVD patients. In...

Mild cognitive impairment (MCI) is associated with age-related alterations in neural oscillatory activity and cerebral hemodynamics, while mobility limitations often restrict participation in conventional exercise-based interventions. This study investigated exploratory, single-arm, within-subject short-term neurovascular and electrophysiological responses to a combined visual and vibration stimulation protocol in older adults with MCI. Cerebral blood flow was assessed using near-infrared...

Chronic pain affects more than half of older adults and has been increasingly linked to cognitive decline, a relationship with profound implications for healthy aging. Ramezani and colleagues examined this association in 1,343 Iranian older adults from the Birjand Longitudinal Aging Study, a well‑characterised cohort from an understudied population. The study has notable strengths: a large sample size, population‑based recruitment, and DAG‑guided covariate selection. However, three...

CONCLUSIONS: Structural and functional muscle indicators showed divergent age-related patterns among rural community-dwelling women. The performance-based 5×STS demonstrated substantially greater relative differences than structural indicators, supporting the inclusion of functional assessments alongside structural measures for age-stratified evaluation in rural settings.

Anti-aging pharmacology has transitioned from early exploratory lifespan-extension studies to a hallmark-informed, multi-level framework that integrates mechanistic, preclinical, and translational evidence. Using a bibliometric-guided, strategy-oriented approach, this review maps the explicit anti-aging drug literature from 2005 to 2025, identifies historically influential compounds, and evaluates their translational readiness. The field converges on three partially overlapping intervention...

CONCLUSIONS: The findings from our study indicate that supporting the psychological and spiritual resources of older adults plays an important role in strengthening the successful aging process. Longitudinal studies on successful aging are recommended.

Aging is associated with structural and functional changes of the vocal folds that may result in presbyphonia, often perceived as a weak or shaky voice. However, the quantitative characterization of underlying age-related vocal tremor across the adult lifespan remains limited. This cross-sectional study investigated the characteristics of vocal tremor across the adult lifespan using automated acoustic analysis. A total of 291 native speakers aged 18-94 years were recruited and underwent...

Hippocampal atrophy across the lifespan is associated with cognitive decline, as is difficulty understanding speech-in-noise. The hippocampus contains subfields with distinct functions, but their involvement in hearing-related differences is unknown. Here, we used HippUnfold, an automated hippocampal unfolding and subfield segmentation method, together with Multiple Factor Analysis (MFA) to examine shared variance across hippocampal structure, hearing-related function, and cognition in younger...

Aging disrupts physiological homeostasis, impairing thermoregulation, metabolism, and water balance, but the underlying neural mechanisms remain unclear. Here, we identify arginine vasopressin (AVP) neurons in the supraoptic nucleus (SON) of the hypothalamus as a critical driver of these changes in male mice. Single-nucleus RNA-sequencing revealed Avp among the most upregulated neuronal transcripts with age. Aged SON^(AVP) neurons displayed enlarged size and heightened excitability, features...

The goal of developing interventions to slow ageing is not only lifespan extension but more importantly to increase healthspan, the period of life spent in active good health. Nutritional interventions have emerged as a potential strategy to maintain health with age. Testing these interventions for effects on human ageing would take several years and require large cohort sizes. We therefore employed C. elegans as a rapidly ageing model organism to investigate the effects of two commercially...

CONCLUSIONS: This study indicates that retaining ≥ 20 teeth, brushing at least once daily, and using dentures are associated with a lower likelihood of anxiety symptoms among the elderly population. Further prospective studies are warranted to confirm these associations.
