(AP) -- Federal regulators under President Barack Obama have sharply shifted course on long-standing policy toward pharmaceutical residues in the nation's drinking water, taking a critical first step toward regulating some of the contaminants while acknowledging they could threaten human health. http://www.physorg.com/news180713428.html Space & Earth Tue, 22 Dec 2009 14:20:03 EST news180713428 Boston University School of Medicine (BUSM) researchers at the Slone Epidemiology Center found that black women with high intake of dairy products have a reduced incidence of uterine leiomyomata (fibroids). This report, based on the Black Women's Health Study, appears in the current issue of the American Journal of Epidemiology. http://www.physorg.com/news179150777.html Medicine & Health Fri, 04 Dec 2009 12:16:38 EST news179150777 Animal studies suggest that adding flaxseed oil to the diet could reduce the risk of osteoporosis in post-menopausal women and women with diabetes, according to a report to be published in the International Journal of Food Safety, Nutrition and Public Health. http://www.physorg.com/news178208985.html Medicine & Health Mon, 23 Nov 2009 15:00:01 EST news178208985 Researchers at Johns Hopkins are reporting what is believed to be the first conclusive evidence in men that the long-term ill effects of vitamin D deficiency are amplified by lower levels of the key sex hormone estrogen, but not testosterone. http://www.physorg.com/news177515840.html Medicine & Health Sun, 15 Nov 2009 14:10:01 EST news177515840 Obesity causes more than 100,000 incidents of cancer in the US every year, the American Institute for Cancer Research said in estimates published Friday. http://www.physorg.com/news176749877.html Medicine & Health Fri, 06 Nov 2009 17:30:01 EST news176749877 Trophoblast stem cells (TSCs), cells found in the layer of peripheral embryonic stem cells from which the placenta is formed, are thought to exhibit "immune privilege" that aids cell survivability and is potentially beneficial for cell and gene therapies. Further, the survivability of TSCs has been thought to require the presence of ovarian hormones. However, none of these assumptions has ever been verified. This study, published in the current issue of the journal Cell Transplantation (18:7) has demonstrated that it is the absence of male hormones, rather than the presence of female hormones, that allows extended transplanted cell survivability. http://www.physorg.com/news176047451.html Biology Thu, 29 Oct 2009 17:10:01 EST news176047451 The sex hormone estrogen tempers the killing activity of a specific group of immune cells, the cytotoxic T cells (CTLs), which are known to attack tumor cells and cells infected by viruses. The key player in this process is a cytotoxic T cell molecule which has been known for a long time and which scientists have named EBAG9. http://www.physorg.com/news169120247.html Medicine & Health Mon, 10 Aug 2009 11:20:07 EST news169120247 A study led by researchers at the Ohio State University Comprehensive Cancer Center and Dana-Farber Cancer Institute reveals how late-stage, hormone-independent prostate tumors gain the ability to grow without need of hormones. http://www.physorg.com/news167571379.html Medicine & Health Thu, 23 Jul 2009 12:50:02 EST news167571379 University of California, Berkeley, researchers have found what they think is a critical and, until now, missing piece of the puzzle about how stress causes sexual dysfunction and infertility. http://www.physorg.com/news164337150.html Medicine & Health Tue, 16 Jun 2009 03:00:01 EST news164337150 (PhysOrg.com) -- Why does dishing with a girlfriend do wonders for a woman's mood? http://www.physorg.com/news163178026.html Medicine & Health Tue, 02 Jun 2009 16:14:14 EST news163178026 (AP) -- A little testosterone might be good for adults, but it can cause serious harm to children, federal health officials warned Thursday. The Food and Drug Administration said adults using prescription testosterone gel must be extra careful not to get any of it on children to avoid causing serious side effects. http://www.physorg.com/news160932510.html Medicine & Health Thu, 07 May 2009 16:28:50 EST news160932510 Scientists at the University of Rochester have discovered that the hormone estrogen plays a pivotal role in how the brain processes sounds. http://www.physorg.com/news160765483.html Medicine & Health Tue, 05 May 2009 18:05:07 EST news160765483 (PhysOrg.com) -- People use the colour of your skin to judge how healthy you are, according to researchers at the University of St Andrews. http://www.physorg.com/news157823512.html Medicine & Health Wed, 01 Apr 2009 16:53:08 EST news157823512 New research suggests the hormone kisspeptin shows promise as a potential new treatment for infertility. The research is being presented at the annual Society for Endocrinology BES meeting in Harrogate. Scientists led by Dr Waljit Dhillo from Imperial College London, have shown that giving kisspeptin to women with infertility can activate the release of sex hormones which control the menstrual cycle. This research could lead to a new fertility therapy for women with low sex hormone levels. http://www.physorg.com/news156449617.html Medicine & Health Mon, 16 Mar 2009 19:14:01 EST news156449617 Women who have more years of fertility (the time from first menstruation to menopause) have a lower risk of developing Parkinson`s disease than women with fewer years, according to a large, new study by researchers at Albert Einstein College of Medicine of Yeshiva University. http://www.physorg.com/news154803926.html Medicine & Health Wed, 25 Feb 2009 17:07:41 EST news154803926 Men are more prone to - and likely to die of - heart disease compared with women of a similar age - and sex hormones are to blame, according to a new University of Leicester led study. http://www.physorg.com/news139457786.html Medicine & Health Mon, 01 Sep 2008 03:16:26 EST news139457786 Genes that control percentage of body fat are also responsible for circulating levels of testosterone in men, research published in the latest edition of Clinical Endocrinology shows. The research shows a 23% overlap between the genes that control testosterone and those that regulate body fat composition, suggesting that these two variables are partly controlled by the same set of genes. http://www.physorg.com/news137173251.html Medicine & Health Tue, 05 Aug 2008 16:40:51 EST news137173251
