Abstract Resveratrol obtained in grape seed and skin is structurally similar to a synthetic estrogen diethylstilbestrol. The endogenous estrogen, 17β-estradiol, induces cellular responses by binding the receptor alpha beta. bone fracture due decreased mineral density postmenopausal women linked reduced estrogen. adverse drug reactions of hormone replacement therapy warrant identifying unique na...

OBJECTIVES The loss of ovarian function in women through aging or oophorectomy is often associated with the development of vaginal hyperalgesia that can be alleviated with estrogen replacement. This study examined if ovariectomy in rats would similarly give rise to vaginal hyperalgesia, and, if so, whether estrogen replacement would alleviate it. METHODS Female rats were trained to perform an...

Research in animal models indicates that without estrogen, the effectiveness of exercise for increasing bone mineral in females is reduced. With decreased estrogen levels, there is an increase in the threshold at which strains are detected by bone, in turn reducing the transmission of mechanical to biochemical signals for bone formation. Studies combining estrogen replacement and exercise train...

BACKGROUND Postmenopausal estrogen replacement is widely used in the United States but poses important health risks. PURPOSE To assess the risk for venous thromboembolism with postmenopausal estrogen replacement by using literature review and meta-analysis. DATA SOURCES All relevant English-language studies identified in searches of the MEDLINE (1966 to December 2000), HealthSTAR (1975 to D...

Hormone replacement therapy may protect against cardiovascular disease through several mechanisms that have variable actions on the major determinants of plasma viscosity. Plasma viscosity is an important predictor of incident and recurrent cardiovascular events and mortality in coronary heart disease patients. The effect of estrogen alone or in combination with progestin on plasma viscosity is...

Administration of estrogen replacement therapy (ERT) decreases the incidence of breast cancer, as shown in a double-blind, placebo-controlled randomized trial of the Women's Health Initiative (WHI) in 10,739 postmenopausal women with a prior hysterectomy. Although paradoxical because estrogen is recognized to stimulate breast cancer growth, laboratory data support a mechanism of estrogen-induce...
