Published What can bulls tell us about men? (via sciencedaily.com) Original source
Researchers have found genes in the reproductive organs of bulls that influence fertility. The findings can be transferred to humans, as these genes are also present in men.
Published Helping caregivers help people with dementia eat at home (via sciencedaily.com) Original source
A new study has laid the groundwork for a future intervention designed to help caregivers establish a safe and workable mealtime routine for people with dementia living at home.
Published Double risk of dementia after mouth ulcer virus (via sciencedaily.com) Original source
People who have had the herpes virus at some point in their lives are twice as likely to develop dementia compared to those who have never been infected. A new study confirms previous research on whether herpes can be a possible risk factor for dementia.
Published Exposure to Agent Orange damages brain tissue in ways similar to Alzheimer's disease (via sciencedaily.com) Original source
Agent Orange, an herbicide used during the Vietnam War, is a known toxin with wide-ranging health effects. Even though Agent Orange has not been used for decades, there is increasing interest in its effects on the brain health of aging veterans. A new study reveals the mechanisms by which Agent Orange affects the brain and how those processes can lead to neurodegenerative diseases. The research shows that exposures to Agent Orange herbicidal chemicals damage frontal lobe brain tissue of laboratory rats with molecular and biochemical abnormalities that are similar to those found in early-stage Alzheimer's disease.
Published New epigenetic clocks reinvent how we measure age (via sciencedaily.com) Original source
Investigators unveil a new form of epigenetic clock -- a machine learning model designed to predict biological age from DNA structure.
Published Turning back the clock on photoaging skin (via sciencedaily.com) Original source
A new study examines dermal injections and their impact on skin aging.
Published Clinical trial shows rheumatoid arthritis drug could prevent disease (via sciencedaily.com) Original source
A drug used to treat rheumatoid arthritis could also prevent the disease in individuals deemed to be at risk.
Published Scientists discover biological mechanism of hearing loss caused by loud noise -- and find a way to prevent it (via sciencedaily.com) Original source
Drugs that trap excess zinc in the inner ear could help restore lost hearing or, if administered before an expected loud sound exposure, can protect from hearing loss, study suggests.
Published Non-invasive techniques to detect skin cancer (via sciencedaily.com) Original source
A study has demonstrated that the appearance of ageing skin looks noticeably different compared to younger skin, when examined under polarized laser light. The scientists believe that their new finding could pave the way for new, non-invasive light-based techniques to detect diseases, including cancer, in older individuals. This could significantly enhance early-stage treatment options for various skin conditions.
Published Genetic cause of low birth weight among children conceived after fertility treatment (via sciencedaily.com) Original source
A medical researcher has identified a genetic cause for the increased risk of low birth weight in babies born following assisted reproductive technologies such as IVF.
Published Immune genes are altered in Alzheimer's patients' blood (via sciencedaily.com) Original source
A new study has found the immune system in the blood of Alzheimer's patients is epigenetically altered. That means the patients' behavior or environment has caused changes that affect the way their genes work. Many of these altered immune genes are the same ones that increase an individual's risk for Alzheimer's. Scientists now theorize the cause could be a previous viral infection, environmental pollutants or other lifestyle factors and behaviors.
Published Faulty DNA disposal system causes inflammation (via sciencedaily.com) Original source
Scientists discovered a pathway from mitochondrial DNA replication stress to immune system activation and inflammation, finding that endosomes responsible for disposing of dysfunctional mitochondrial DNA were leaking mitochondrial DNA into the cell and prompting the inflammatory immune response. The pathway provides new targets for therapeutics that disrupt inflammation during aging and disease.
Published Erectile dysfunction drugs may be linked to reduced risk of Alzheimer's disease (via sciencedaily.com) Original source
The drugs used to treat erectile dysfunction may also be associated with a reduced risk of Alzheimer's disease, according to new research. The study does not prove that erectile dysfunction drugs reduce the risk of Alzheimer's disease. It only shows an association.
Published New direct links discovered between the brain and its surrounding environment (via sciencedaily.com) Original source
In a recent study of the brain's waste drainage system, researchers discovered a direct connection between the brain and its tough protective covering, the dura mater. These links may allow waste fluid to leave the brain while also exposing the brain to immune cells and other signals coming from the dura. This challenges the conventional wisdom which has suggested that the brain is cut off from its surroundings by a series of protective barriers, keeping it safe from dangerous chemicals and toxins lurking in the environment.
Published Music may bring health benefits for older adults, poll suggests (via sciencedaily.com) Original source
Three-quarters of people age 50 to 80 say music helps them relieve stress or relax and 65% say it helps their mental health or mood, according to a recent poll. Meanwhile, 60% say they get energized or motivated by music. Virtually all (98%) said they benefit in at least one health-related way from engaging with music.
Published Study finds strongest evidence to date of brain's ability to compensate for age-related cognitive decline (via sciencedaily.com) Original source
Scientists have found the strongest evidence yet that our brains can compensate for age-related deterioration by recruiting other areas to help with brain function and maintain cognitive performance.
Published How ovarian tissue freezing could prevent menopause -- possibly forever (via sciencedaily.com) Original source
A new paradigm around the biological processes of menopause is capturing the attention of scientists. The primary question: can menopause be delayed in healthy women, allowing them to extend their child-bearing years -- and perhaps even forestall some of the health risks and uncomfortable symptoms linked to plummeting estrogen levels?
Published Lighting up Alzheimer's-related proteins to allow for earlier disease detection (via sciencedaily.com) Original source
Many neurodegenerative diseases, including Alzheimer's and Parkinson's, are difficult to diagnose before symptoms begin to appear. However, disease-related biomarkers such as aggregated proteins called amyloids could provide important insight much earlier, if they can be readily detected. Researchers have developed one such method using an array of sensor molecules that can light up amyloids. The tool could help monitor disease progression or distinguish between different amyloid-related conditions.
Published Scientists discover a potential way to repair synapses damaged in Alzheimer's disease (via sciencedaily.com) Original source
While newly approved drugs for Alzheimer's show some promise for slowing the memory-robbing disease, the current treatments fall far short of being effective at regaining memory.
Published Polycystic ovary syndrome tied to memory, thinking problems (via sciencedaily.com) Original source
People with polycystic ovary syndrome may be more likely to have memory and thinking problems in middle age, according to new research. The study does not prove that polycystic ovary syndrome causes cognitive decline. It only shows an association.
