Leading researchers from UNSW and Harvard have identified that replacing two naturally molecules in mice can reverse the aging process of blood vessels, boosting their exercise capacity and physical endurance.
A new report finds people with 'a lot of trouble hearing' are twice as likely to suffer from accidental injuries.
Thousands of older people in low and middle-income countries are at risk of abuse and human rights violations when being admitted to care homes, according to new research led by the University of East Anglia (UEA). The study provides the first systematic analysis of admissions practices for residential long-term care facilities, assessing the extent to which older people are involved in admission decisions and whether current practices respect fundamental human rights.
Putting mice on a diet containing low amounts of the essential amino acid methionine triggered the formation of new blood vessels in skeletal muscle, according to a new study from Harvard T.H. Chan School of Public Health. The finding adds insight to previous research showing that a methionine-restricted diet extends lifespan and healthspan, suggesting that improved vascular function may contribute to these benefits.
MIT researchers have reversed age-related endurance loss in mice by treating them with a compound that promotes new blood vessel growth. Their study, led by senior author Leonard Guarente, found the compound, which reactivates longevity-linked sirutin proteins, promotes blood vessel and muscle growth, boosting endurance of elderly mice by up to 80 percent.
Despite confusing messages, new data shows all moderate or vigorous activity -- even when done in short bursts throughout the day -- can reduce Americans' risk of disease and death, according to research appearing in the Journal of the American Heart Association.
Scientists identify mechanism behind vascular aging, muscle demise in mice. Treatment with chemical compounds reversed vascular aging, stimulated blood vessel growth and blood flow, boosted exercise capacity in aging animals.
An enzyme called SIRT1 declines in the blood vessels with age and restoring it reverses the effects of vascular aging. After receiving a supplement called NMN, older mice showed increased capillary density, blood flow, mobility, and endurance.
Older adults often complain about forgetting, but Penn State psychologists suggest that another problem may be misremembering.
The largest-ever survey of care home staff in England, led by UCL researchers, has found that neglectful behaviors are widespread.
