Plasma Dilution After Myocardial Ischemia-Reperfusion Injury Promotes Cardiac Repair, Heart Performance, and Recovery of Motor Function and Endurance in Old Mice

17 hours 14 minutes ago
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

17 hours 14 minutes ago
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

17 hours 14 minutes ago
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)

17 hours 14 minutes ago
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.

Feeling Younger as an Indicator of Better Overall Intrinsic Capacities in the INSPIRE-T Cohort

17 hours 14 minutes ago
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

1 day 17 hours ago
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

1 day 17 hours ago
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

1 day 17 hours ago
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

1 day 17 hours ago
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...

Replacement-Based Ageing Interventions for Systemic Rejuvenation: Shaping Longevity Science and Clinical Directions

1 day 17 hours ago
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

1 day 17 hours ago
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

1 day 17 hours ago
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

2 days 17 hours ago
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...
