A large survey of women in California shows significant racial and ethnic differences in the types of personal care products women use on a daily basis. Because many personal care products contain endocrine disrupting chemicals (EDCs) like parabens and phthalates that interfere with the body's hormones, the findings could shed light on how different products influence women's exposures to harmful chemicals that contribute to health inequities.
Researchers at IRB Barcelona identify that the expression of ancestral fragments of viral DNA results in a strong inflammatory response and causes breast tissue dysfunction. This viral DNA accumulation has also been observed in some types of cancer, such as triple-negative breast cancer, and it may play a key role in determining metastatic potential. The work has been published in the journal Cell Stem Cell.
Alterations in the epigenetic programming of hatchery-raised steelhead trout could account for their reduced fertility, abnormal health and lower survival rates compared to wild fish, according to a new Washington State University study.
A new study led by Russ Van Horn, Ph.D., takes the most detailed look yet at the dens of this species. Van Horn, a population sustainability scientist, leads San Diego Zoo Wildlife Alliance's Andean bear conservation program. He was joined by colleagues from the University of British Columbia's Department of Forest and Conservation Sciences and the Spectacled Bear Conservation Society. The study's findings may aid conservation planners in locating den sites or guiding management for suitable bear habitat.
New King's College London research - funded by the Medical Research Foundation and published today in Translational Psychiatry - reveals how subtle differences in brain connectivity could offer a sign of risk for postpartum psychosis in women.
Early preterm births may be dramatically decreased with docosahexaenoic acid (DHA) supplements, with a dose of 1000 mg more effective for pregnant women with low DHA levels than the 200 mg found in some prenatal supplements.
In a large-animal study, researchers have shown that heart attack recovery is aided by injection of heart muscle cells derived from human induced pluripotent stem cell line, or hiPSCs, that overexpress cyclin D2. This research, published in the journal Circulation, used a pig model of heart attacks, which more closely resembles the human heart in size and physiology, and thus has higher clinical relevance to human disease, compared to studies in mice.
Mother fence lizards that experience stress during pregnancy give birth to male offspring with shortened telomeres, or bits of non-coding DNA that cap the ends of chromosomes, according to a Penn State-led study. Shorter telomeres are associated with decreased lifespan in humans; therefore, the team's findings may have implications for human longevity.
Scientists show for the first time that the primary cilium - a sensing 'organ' of cells - helps the cells that form the lymphatic vessels of mammals to grow into a functional and locally responsive network, not only during prenatal development but also during inflammation and wound healing. This discovery, in a study by the open access publisher Frontiers, could inspire new medical therapies.
Australian researchers have documented the diversity of cells in the human breast, explaining the relationship between healthy breast cells and breast cancer cells. The research, which relied on expertise spanning from breast cancer biology through to bioinformatics, measured gene expression in single cells taken from healthy women and cancerous breast tissue, including tissue carrying a faulty BRCA1 gene. This enabled the researchers to create an 'RNA atlas' that details the different cells found in these tissues.
