Introduced in the 1960s, oral contraceptives have been used by about 80 percent of women in the United States at some point in their lives. For women without pre-existing risks for heart disease, the early formulations were generally safe, and the newer ones appear to be even safer, but all the risks and benefits are yet to be established, especially as women's lifestyles change and new forms of contraceptives become available, according to specialists in women's heart disease at Cedars-Sinai Medical Center. http://www.physorg.com/news151151902.html Medicine & Health Wed, 14 Jan 2009 10:38:22 EST news151151902 The molecular details of Aromatase, the key enzyme required for the body to make estrogen, are no longer a mystery thanks to the structural biology work done by the Ghosh lab at the Hauptman-Woodward Medical Research Institute (HWI) in Buffalo, New York. Dr. Debashis Ghosh's solution of the three-dimensional structure of aromatase is the first time that scientists have been able to visualize the mechanism of synthesizing estrogen. http://www.physorg.com/news150556571.html Medicine & Health Wed, 07 Jan 2009 13:16:11 EST news150556571 A secondary analysis of a large, multicenter clinical trial has shown that a diet loaded with fruits, vegetables and fiber and somewhat lower in fat compared to standard federal dietary recommendations cuts the risk of recurrence in a subgroup of early-stage breast cancer survivors - women who didn't have hot flashes - by approximately 31 percent. These patients typically have higher recurrence and lower survival rates than breast cancer patients who have hot flashes. The study team, led by researchers at the Moores Cancer Center at the University of California, San Diego, along with six other sites, including the University of California, Davis, reported its results online December 15, 2008, in the Journal of Clinical Oncology. http://www.physorg.com/news148624645.html Medicine & Health Tue, 16 Dec 2008 04:37:25 EST news148624645
