Published Research challenges current thinking on the genetic causes of very early menopause (via sciencedaily.com) Original source
The genetic causes of very early menopause will have to be reconsidered after researchers found that nearly all women who carried variations thought to cause the condition in fact had their menopause at an older age.
Published Helping 'good' gut bacteria and clearing out the 'bad' -- all in one treatment (via sciencedaily.com) Original source
Probiotics can help maintain a healthy gut microbiome or restore populations of 'good bacteria' after a heavy course of antibiotics. But now, they could also be used as an effective treatment strategy for certain intestinal diseases, such as Crohn's disease. Researchers have developed a microgel delivery system for probiotics that keeps 'good' bacteria safe while actively clearing out 'bad' ones. In mice, the system treated intestinal inflammation without side effects.
Published Exposure to dioxins can worsen thyroid function (via sciencedaily.com) Original source
Exposure to dioxins can negatively impact thyroid function, according to a study presented Thursday at ENDO 2023, the Endocrine Society's annual meeting in Chicago, Ill.
Published A 'pinch' of mineral salts helps the noncaloric sweeteners go down (via sciencedaily.com) Original source
Perfect noncaloric replacements for sugar and high fructose corn syrup just don't exist yet. For example, some alternatives have a lingering sweet aftertaste and lack a sugar-like mouthfeel, leaving some consumers unsatisfied. Now, researchers propose adding blends of nutritionally important mineral salts to make noncaloric sweeteners seem more like the real thing. Taste-testers indicated that these blends gave zero- and low-calorie drinks a better flavor.
Published New study links contraceptive pills and depression (via sciencedaily.com) Original source
Women who used combined contraceptive pills were at greater risk of developing depression than women who did not, according to a new study. Contraceptive pills increased women's risk by 73 per cent during the first two years of use.
Published How breast cancer arises (via sciencedaily.com) Original source
Researchers trace the origin of certain breast cancers to genomic reshuffling -- rearrangement of chromosomes -- that activates cancer genes and ignites disease. The finding offers a long-missing explanation for many cases of the disease that remain unexplained by the classical model of breast cancer development. The study shows the sex hormone estrogen -- thus far thought to be only a fuel for breast cancer growth -- can directly cause tumor-driving genomic rearrangements.
Published Gamma delta T cells can fight aggressive breast cancer (via sciencedaily.com) Original source
Researchers discover a mechanism by which cancer cells escape the immune system.
Published Osteoporosis treatments may benefit from discovery of key driver of low bone density (via sciencedaily.com) Original source
Scientists have pinpointed a key driver of low bone density, a discovery that may lead to improved treatments with fewer side effects for women with osteoporosis. The findings reveal that loss of an epigenetic modulator, KDM5C, preserves bone mass in mice. KDM5C works by altering epigenetic 'marks,' which are akin to 'on' and 'off' switches that ensure the instructions written in DNA are used at the right time and in the right place.
Published Early menopause, later start to hormone therapy may increase risk of Alzheimer's disease (via sciencedaily.com) Original source
Women are more likely than men to develop Alzheimer's disease (AD), with women making up two-thirds of the population living with AD. A new study sheds light on the relationship between the risk of Alzheimer's disease and age of menopause and use of hormone therapy (HT).
Published Is bone health linked to brain health? (via sciencedaily.com) Original source
People who have low bone density may have an increased risk of developing dementia compared to people who have higher bone density. The study does not prove that low bone density causes dementia. It only shows an association.
Published Study finds similar association of progestogen-only and combined hormonal contraceptives with breast cancer risk (via sciencedaily.com) Original source
There is a relative increase of 20% to 30% in breast cancer risk associated with both combined and progesterone-only contraceptives, whatever the mode of delivery, though with five years of use, the 15-year absolute excess incidence is at most 265 cases per 100,000 users, according to a new study.
Published Disproportionate percentage of females with unexplained infertility have gene variants known to cause heart problems, cancer (via sciencedaily.com) Original source
About 17% of women with unexplained infertility also have gene variants known to cause disease, from common conditions like heart disease to rare problems like ALS, researchers report.
Published Humans bite back by deactivating mosquito sperm (via sciencedaily.com) Original source
New research makes it likely that proteins responsible for activating mosquito sperm can be shut down, preventing them from swimming to or fertilizing eggs.
Published Scientists discover a new way to help prevent breast cancer 'time bomb' (via sciencedaily.com) Original source
Scientists have discovered why breast cancer cells that have spread to the lungs may 'wake up' following years of sleep -- forming incurable secondary tumors. Their research reveals the mechanism that triggers this breast cancer 'time bomb' -- and suggests a strategy to defuse it.
Published Two-pronged immunotherapy eliminates metastatic breast cancer in mice (via sciencedaily.com) Original source
Researchers have identified a way to treat the area surrounding breast tumors that have spread to bone so that such tumors become vulnerable to attack by the body's immune system. When the researchers boosted the activity of certain immune cells, called T cells and macrophages, these immune cells worked together to clear metastatic breast tumors that had spread to the bones of mice.
Published Study reveals new understanding of how androgen therapy affects breast tissue (via sciencedaily.com) Original source
New insights into the effects of a hormonal treatment on transgender men could have implications for the treatment of breast cancer.
Published Decades-long suffering from obstetric injuries (via sciencedaily.com) Original source
Bowel leakage, the need for anal incontinence protection and a restricted social life may cause severe, decades-long suffering among women with obstetric injuries to the anal opening, according to a new study.
Published Microcalcification 'fingerprints' can yield info about cancer (via sciencedaily.com) Original source
An interdisciplinary collaboration 10 years in the making used a materials science approach to 'fingerprint' the calcium mineral deposits known as microcalcifications that reveal pathological clues to the progression of breast cancer and potentially other diseases.
Published Migraines during menstruation: Low estrogen levels paired with higher CGRP levels may jump start migraine (via sciencedaily.com) Original source
As estrogen levels fluctuate, a new study has found for female participants with migraine, their levels of the protein calcitonin gene-related peptide (CGRP) that plays a key role in starting the migraine process also fluctuate.
Published Air pollution speeds bone loss from osteoporosis (via sciencedaily.com) Original source
Elevated levels of air pollutants are associated with bone damage among postmenopausal women, according to new research. The effects were most evident on the lumbar spine, with nitrous oxides twice as damaging to the area than seen with normal aging.
