Estrogen seems to act like a middleman in its positive effect on the brain, raising the possibility that future drugs may bypass the carcinogenic hormone altogether while reaping its benefits. http://www.physorg.com/news179505580.html Medicine & Health Tue, 08 Dec 2009 14:40:42 EST news179505580 A compound in coffee has been found to be estrogenic in studies by Texas AgriLife Research scientists. http://www.physorg.com/news177249971.html Medicine & Health Thu, 12 Nov 2009 12:20:02 EST news177249971 Researchers at the University of Wisconsin-Madison School of Medicine and Public Health have eliminated cervical cancer in mice with two FDA-approved drugs currently used to treat breast cancer and osteoporosis. http://www.physorg.com/news177008338.html Medicine & Health Mon, 09 Nov 2009 17:10:02 EST news177008338 New research shows that during natural menstrual cycles, women with asthma who were not taking oral contraceptives (OC) had lower exhaled nitric oxide levels (eNO), a marker of airway inflammation associated with asthma, than women who were taking OC. http://www.physorg.com/news176622901.html Medicine & Health Thu, 05 Nov 2009 07:30:01 EST news176622901 Eighteen years ago this month the National Institutes of Health (NIH) announced that it would sponsor a landmark study to examine women and cardiovascular disease. Known as the Women's Health Initiative (WHI), the study enrolled more than 161,000 women. By 2004 however, the government had ended two arms of the study involving estrogen after researchers found it posed a small but detrimental risk for stroke to postmenopausal women taking the hormone. The findings caught many members of the scientific community by surprise as estrogen had previously been shown to protect the brain from stroke in animal models. http://www.physorg.com/news176491384.html Medicine & Health Tue, 03 Nov 2009 19:10:01 EST news176491384 Hormone replacement therapy (HRT) to treat menopausal estrogen deficiency has been in widespread use for over 60 years. Several observational studies over the years showed that HRT use by younger postmenopausal women was associated with a significant reduction in total mortality; available evidence supported the routine use of HRT to increase longevity in postmenopausal women. However, the 2002 publication of a major study, the Women's Health Initiative (WHI), indicated increased risk for certain outcomes in older women, without increasing mortality. This sparked debate regarding potential benefits or harm of HRT. http://www.physorg.com/news175965554.html Medicine & Health Wed, 28 Oct 2009 16:40:02 EST news175965554 She was only 30 years old, but she was experiencing the classic symptoms of a stroke.
