Published Damage to cell membranes causes cell aging (via sciencedaily.com) Original source
Researchers have discovered that damage to the cell membrane promotes cellular senescence, or cell aging.
Published Compounds in female ginseng could lead to new osteoporosis treatments (via sciencedaily.com) Original source
With ever-increasing life expectancy comes the challenge of treating age-related disorders such as osteoporosis. Although there are effective drugs for treating this metabolic bone disease, they can be expensive and have side effects, limiting their availability to some people. In the search for alternative drug candidates, researchers have discovered and fully replicated a compound from a botanical source, female ginseng, that had potent anti-osteoporotic activity in cellular tests.
Published How AI can help spot early risk factors for Alzheimer's disease (via sciencedaily.com) Original source
Scientists have found a way to predict Alzheimer's Disease up to seven years before symptoms appear by analyzing patient records with machine learning.
Published Researchers are using RNA in a new approach to fight HIV (via sciencedaily.com) Original source
A pharmacy associate professor has developed a novel nanomedicine loaded with genetic material called small interfering RNAs (siRNA) to fight human immunodeficiency virus (HIV) using gene therapy.
Published Annual breast cancer screening beginning at 40 saves lives (via sciencedaily.com) Original source
Annual breast cancer screening beginning at age 40 and continuing to at least age 79 results in the highest reduction in mortality with minimal risks.
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 Menopause and migraines: New findings point to power of prevention (via sciencedaily.com) Original source
Women who have both migraines and a long-term history of hot flashes and/or night sweats have a slightly higher risk of heart disease and stroke, and young women who have migraines have a higher risk of later persistent menopause symptoms, according to two new papers based on a data from a long-term study of the same group of women from their young adult to middle-age years.
Published Strongest contender in decades in fight against breast cancer (via sciencedaily.com) Original source
For decades, hormonal treatment of breast cancer has been going in one direction -- blocking estrogen. Now a global study has discovered there may be another, less toxic way to defeat the most common form of breast cancer.
Published Novel technique has potential to transform breast cancer detection (via sciencedaily.com) Original source
An innovative breast imaging technique provides high sensitivity for detecting cancer while significantly reducing the likelihood of false positive results. Researchers said the technique has the potential to offer more reliable breast cancer screening for a broader range of patients.
Published The unexpected long-term consequences of female fertility (via sciencedaily.com) Original source
The constant remodeling of the organs of the female reproductive tract during the reproductive cycle leads to fibrosis and chronic inflammation over the years. Scientists have now uncovered these unexpected long-term consequences of female reproductive function in mice.
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 Destroying tumor cells with calcium (via sciencedaily.com) Original source
Calcium ions are essential for cells, but can be toxic in higher concentrations. A team of researchers has now designed and prepared a combination drug that kills tumor cells by modulating the calcium influx into the cell. An external calcium source is not necessary because only the calcium ions already present in the tumor tissue are used, according to a new study.
Published Women exposed to toxic metals may experience earlier aging of their ovaries (via sciencedaily.com) Original source
Middle-aged women who are exposed to toxic metals may have fewer eggs in their ovaries as they approach menopause, according to new research.
Published Cold water swimming improves menopause symptoms (via sciencedaily.com) Original source
Menopausal women who regularly swim in cold water report significant improvements to their physical and mental symptoms, finds a new study.
Published Walking fitness can predict fracture risk in older adults (via sciencedaily.com) Original source
The ability to walk one kilometer comfortably can help predict fracture risk, according to researchers. The findings suggest that simply asking a patient about walking limitation could allow clinicians to identify those in need of further bone health screening and prescribe interventions that could prevent fractures from occurring.
Published Early detection of breast cancer: Study confirms the effectiveness of a new approach (via sciencedaily.com) Original source
Early detection of disease is considered positive -- but what if it finds 'too much'? While early diagnosis can improve the chances of recovery, early detection can also have unwanted side effects. After all, not everything that is found would have become life-threatening in the course of the disease. TOSYMA, the world's largest randomized diagnostic superiority study on early breast cancer detection, has now investigated whether the innovative DBT+SM method for early breast cancer detection also has such an effect -- and was once again able to hint on advantages of the approach over the screening standard by finding more early tumor stages of tumor grades 2 and 3.
Published Study pinpoints breast cancer 'cells of origin' in high-risk women (via sciencedaily.com) Original source
Australian scientists have pinpointed likely 'cells of origin', the source cells that can grow into breast cancer, in women carrying a faulty BRCA2 gene who are at high risk of developing the disease. The study also showed these cells have potential to be targeted with an existing cancer drug to delay tumour growth, in findings that may lead to future preventive treatments for the disease.
Published Incontinence could point to future disability (via sciencedaily.com) Original source
Having more frequent urinary incontinence and leakage amounts is associated with higher odds of disability, according to researchers.
Published Infertility: Sperm need a breakthrough for fertilization (via sciencedaily.com) Original source
A new study identifies the defective function of CatSper, an ion channel controlling calcium levels in sperm, as a common cause of seemingly unexplained male infertility. CatSper-deficient human sperm fail to fertilize the egg, because they cannot penetrate its protective vestments. Thus far, this sperm channelopathy has remained undetectable. Scientists have unravelled CatSper's role in infertility using a novel laboratory test that identifies affected men.
Published Genetic variants underlying male bisexual behavior, risk-taking linked to more children, study shows (via sciencedaily.com) Original source
Because same-sex sexual behavior does not result in offspring, evolutionary biologists have long wondered how the genes associated with this behavior have persisted in the human genome, and whether they will remain in the future. A new study suggests that part of the explanation -- specifically for male bisexuals -- has to do with risk-taking behavior.
