Background:Soy consumption may protect against breast cancer through modification of estrogen metabolism.Objectives:We examined the effect of soy foods on urinary estrogens and the 2-hydroxy (OH)/16α-OH estrone (E1) ratio in two dietary interventions with premenopausal women.Subjects/methods:The Breast, Estrogens, And Nutrition (BEAN1) study was a 2-year(More)
One of the hypothesized protective mechanisms of soy against breast cancer involves changes in estrogen metabolism to 2-hydroxy (OH) and 16α-OH estrogens. The current analysis examined the effect of soy foods on the 2:16α-OH E(1) ratio among premenopausal women during a randomized, crossover intervention study; women were stratified by equol producer(More)
PURPOSE To evaluate the feasibility of bedside Technetium99-methoxy-isobutyl-isonitrile (99mTc-MIBI) cardiac imaging to assess perfusion after thrombolytic therapy (TT) for myocardial infarction (MI). METHODS We studied 9 patients (mean age 59 +/- 9 years) submitted to TT with 100 mg of rt-PA in 90 minutes within the 6 hours of the onset of MI with(More)
