We assessed the effects of treatment on plasma levels of tissue-type plasminogen activator (tPA), von Willebrand factor (vWF), vWF-propeptide (vWF:AgII) and big-endoth...
Estetrol (E4) is a pregnancy-specific D-ring metabolite of estradiol (E2) and estriol (E3) produced by the human fetal liver and present in both male and female fetuses. In adults, female exposure is restricted to the gestational period. We report that E4, dose-dependently, prevents the growth of chemically induced (7,12-dimethylbenz(a)anthracene, DMBA) mammary tumors in female Sprague-Dawley r...
OBJECTIVE To assess whether the combined oral contraceptive (COC) ethinylestradiol (EE) 20 μg/drospirenone 3 mg taken in a 24/4-day regimen (ie, 4-day hormone-free interval) is more effective than an EE 20 μg/desogestrel (DSG) 150 μg COC taken in a 21/7-day regimen (ie, 7-day hormone-free interval) in reducing hormone withdrawal-associated symptoms (HWAS). METHODS This double-blind, randomize...
The presence of steroid hormones in lake waters causes contamination aquatic ecosystems, which may cause endocrine alterations the organisms that inhabit them.
