Adding the nutrient selenium to diets protects against obesity and provides metabolic benefits to mice, according to a study published today in eLife.
Drinking beetroot juice promotes a mix of mouth bacteria associated with healthier blood vessels and brain function, according to a new study of people aged 70-80.
University of Rochester researchers have created a 3D lab model using patient-derived tissues that mimics the areas of the retina affected in age-related macular degeneration (AMD), which affects an estimated 196 million people. They believe this could lead to finding specific drugs for individual patients to treat a disease that currently has no cure.
GlyNAC - a combination precursors of the natural antioxidant glutathione - improved many age-associated defects in older humans boosting muscle strength and cognition.
Monitoring the progression of multiple sclerosis-related gait issues can be challenging in adults over 50 years old, requiring a clinician to differentiate between problems related to MS and other age-related issues. To address this problem, researchers are integrating gait data and machine learning to advance the tools used to monitor and predict disease progression.
Research suggests that chronic viral infections have a profound and lasting impact on the immune system in ways that are similar to those seen during aging. Using systems immunology and artificial intelligence, researchers profiled and compared immune responses in a cohort of aging individuals, people with HIV on anti-retroviral therapy, and people infected with hepatitis C before and after the virus was treated with a drug that has up to a 97% cure rate.
A study published led by Dr. Katherine King, associate professor at Baylor College of Medicine and Texas Children's Hospital, shows for the first time that long-term infection and chronic inflammation drive CH mediated by the loss of Dnmt3a function. In addition, the study offers key insights into the mechanism by which chronic inflammation leads to CH and demonstrates the critical role of DNMT3a in regulating normal HSC responses to infections.
A recent Oregon State University study found that when people feel they have resolved an argument, the emotional response associated with that disagreement is significantly reduced and, in some situations, almost entirely erased.
In spring 2020, when the first wave of the coronavirus pandemic hit Finland, older adults drastically reduced their out-of-home activities. During the period of government restrictions, physical exercise was the most common reason to leave home.
A new study suggests that Sargramostim, a medication often used to boost white blood cells after cancer treatments, is also effective in treating and improving memory in people with mild-to-moderate Alzheimer's disease. The University of Colorado Anschutz Medical Campus presents evidence that Sargramostim has both disease-modifying and cognition-enhancing activities in Alzheimer's disease patients.
