Living longer or healthier? Genetic discovery in worms suggests they can be separated
Gene identified in worms controls how resources are allocated for stress resilience, longevity and fertility.
Slug, a stem cell regulator, keeps breast cells healthy by promoting repair of DNA damage
A new biomedical research study finds a transcription factor called Slug contributes to breast cell fitness by promoting efficient repair of DNA damage. The absence of Slug leads to unresolved DNA damage and accelerated aging of breast cells.
Advantages for stress urinary incontinence surgery
One of the most commonly performed surgeries to treat stress urinary incontinence in women may have better long-term results than another common surgical technique, according to a new study. The retrospective study of more than 1,800 cases at Mayo Clinic from 2002 to 2012 found that the need for additional surgery was twice as high after a transobturator sling surgery compared with a retropubic sling procedure.
Wearing hearing aid may help protect brain in later life
A new study has concluded that people who wear a hearing aid for age-related hearing problems maintain better brain function over time than those who do not.
Larger drug trials that intervene earlier needed for Alzheimer’s disease
There are currently no drugs that stop or inhibit Alzheimer’s disease. Despite drug trials showing plaque reduction in the brain, the patients’ cognitive function did not improve. Would the results be different if it were possible to design studies that intervene much earlier on in the disease, before cognition is affected? This is what an international study has attempted to facilitate.
Indications why older people are more susceptible to Alzheimer’s disease
The risk of developing Alzheimer’s disease increases with age. Medical researchers have uncovered a possible cause for this connection: Certain molecules involved in the disease, termed tau-proteins, spread more easily in the aging brain.
Combat veterans more likely to experience mental health issues in later life
Military veterans exposed to combat were more likely to exhibit signs of depression and anxiety in later life than veterans who had not seen combat, a new study shows.
