Plasma Dilution After Myocardial Ischemia-Reperfusion Injury Promotes Cardiac Repair, Heart Performance, and Recovery of Motor Function and Endurance in Old Mice
Myocardial infarction (MI) is the leading cause of cardiovascular-related deaths worldwide, with risk increasing sharply with age. Fibrosis and inflammation occur soon after a pathological event and reflect perturbation of tissue repair that accompanies aging in general. Yet not old, but young animals are typically used for studying MI, emphasizing the unmet need for more relevant preclinical models. We previously determined that plasma dilution, also termed neutral blood exchange (NBE)...
Environmental Enrofloxacin Exposure as a Modifiable Driver of Mitochondria-Mediated Intestinal Aging and Barrier Dysfunction
Environmental antibiotic pollution is an underexplored contributor to gut aging and chronic intestinal diseases. We provide evidence that chronic exposure to enrofloxacin (ENR), a commonly detected veterinary antibiotic, accelerates gut aging and disease progression through a mitochondria-centered mechanism. In a population-based cross-sectional analysis, recent antibiotic use was associated with increased biological age and a higher risk of diarrhea in middle-aged and older adults, supporting a...
The environmental stress response regulates biophysics of the cytoplasm and survival in quiescence
All organisms employ strategies to cope with changing environmental conditions. In budding yeast, nutrient deprivation induces a reversible non-proliferative state known as quiescence, characterized by extensive remodeling of gene expression, metabolism, and cellular biophysical properties. Yeast cells survive prolonged periods of starvation-induced quiescence, provided they can respire in the early stages of glucose withdrawal, and blocking respiration causes premature aging and markedly...
Association between gut microbiota and sarcopenia in older adults: a cross-sectional analysis from the second wave of the Birjand Longitudinal Aging Study (BLAS)
CONCLUSION: This study demonstrates that specific gut microbial profiles are significantly associated with sarcopenia. Akkermansia and Lactobacillus were associated with sarcopenia, although greater Roseburia levels were beneficial. These microbial signatures are associated with sarcopenia and warrant further longitudinal investigation.

What matters most to the patient - a qualitative study of older patients in a geriatric ward
CONCLUSIONS: What mattered most to the patients was closely related to the World Health Organization's recommendations for ethical and good quality health care. Generally, the patients agreed on what mattered most. Further studies are needed to enrich the understanding of what is important to older patients.
Feeling Younger as an Indicator of Better Overall Intrinsic Capacities in the INSPIRE-T Cohort
CONCLUSIONS: This study demonstrates that feeling younger than one's age is associated with better overall intrinsic capacities at baseline and lesser decline over the monitoring period. Routine assessment of subjective age could help to identify individuals who may benefit from prevention strategies and could promote patient-centered care by providing deeper insights into individuals' perceptions of aging.
The role of ultrasound in addressing neurodegenerative diseases: A review of mechanisms, applications, and challenges
With the aging of the global population, neurodegenerative diseases have become a major public health challenge. Currently, there are many limitations in the traditional treatment of neurodegenerative diseases, such as medicine, deep brain stimulation, transcranial magnetic stimulation, and transcranial direct current stimulation, including the inability to penetrate the blood-brain barrier (BBB) accurately and challenges in achieving precise and quantitative control during the treatment...
Uridine restores oocyte quality and mitigates female reproductive aging by inhibition of ferroptosis in mice
Advanced maternal age is a key factor in female infertility, primarily due to declines in ovarian reserve and oocyte quality. However, the metabolic mechanisms underlying reproductive aging remain unclear. Here, we show that uridine levels in the plasma and ovaries of aged mice are significantly reduced compared with young controls. Building on this, we find that uridine supplementation significantly improves meiotic maturation, fertilization, and early embryonic development of aged oocytes,...
Aging-associated modulation of UFMylation impairs proteostasis in C. elegans
The attachment of Post-Translational Modifications (PTMs) to proteins regulates their activities and stability. Here we utilized the nematode Caenorhabditis elegans to test whether UFMylation, a PTM which affects key biological functions, regulate aging and protein homeostasis (proteostasis). We find that lowering UFMylation extends lifespan and mitigates the toxicity of aggregation-prone proteins that underlie the development of neurodegenerative disorders in humans. Mass spectrometric analysis...
Multimodal data analysis reveals asynchronous aging dynamics across female reproductive organs
Female reproductive aging has systemic health implications, yet tissue-level dynamics remain poorly understood. Here we integrate deep learning analysis of 1,112 histology images with RNA sequencing from 659 samples across seven female reproductive organs in donors aged 20-70 years. We uncover asynchronous trajectories: the ovary ages gradually, whereas the uterus shows an abrupt molecular and morphological shift around menopause. This uterine transition is independently supported by plasma...
Witnessing Interparental Violence in Childhood and Frailty in Adulthood: Evidence From a National Population-Based Study in China
CONCLUSIONS AND IMPLICATIONS: Witnessing interparental violence in childhood is significantly linked to higher frailty in adulthood. Interventions addressing domestic violence may contribute to healthier aging outcomes.
Replacement-Based Ageing Interventions for Systemic Rejuvenation: Shaping Longevity Science and Clinical Directions
Biological and synthetic replacement-based ageing interventions hold substantial potential to reverse many forms of age-related damage simultaneously and extend healthy lifespan beyond what can be achieved with conventional therapeutics. In this Perspective, we discuss recent insights, unmet needs, and emerging trajectories that are catalysing research and clinical development of replacement-based treatments and synergistic strategies for multi-targeted damage removal and export at the...

Unequal healthy ageing trajectories across Europe: socioeconomic development and age-related disease burden in the European Union and South-Eastern European countries
Although life expectancy has increased, many of the added years are lived in poor health, highlighting growing inequalities in ageing trajectories. Despite the increasing need for ageing-related health strategies, non-EU European countries remain underrepresented in comparative research, leaving limited evidence on healthy ageing disparities between EU and South-Eastern European (SEE) nations. This study explored variations in key health and socioeconomic indicators of societal ageing and...
A telomere-lipid-immunity axis linking viral integration to autoimmune disease risk
Autoimmune diseases rise steeply with biological aging, reflecting progressive failure of immune regulation. Inherited chromosomally integrated human herpesvirus 6 (iciHHV-6) represents a unique lifelong viral exposure in which the viral genome is embedded within host telomeres, potentially altering leukocyte telomere length (LTL), a core biomarker of immune aging. Circulating metabolites may further modify these viral-telomeric interactions. We analyzed 156,927 UK Biobank participants free of...

Neighborhood Racial Composition, Socioeconomic Status, and Obesity Among Older Black Adults
ObjectivesObesity is common among older Black adults, but its underlying drivers, such as neighborhood racial composition (NRC), remain understudied. This study examined the association between NRC and obesity among older Black adults, evaluating the role of individual-level socioeconomic status (SES).MethodsData from the Nashville Stress and Health Study was linked to five-year estimates from the American Community Survey. Obesity was defined as body mass index ≥30 kg/m². NRC was measured with...
