Background: The aim of this prospective randomized clinical trial was to determine the optimal endometrial preparation protocol by comparing the clinical outcome of two methods of endometrial preparation in FET cycles, that is, oral estradiol and 17 β-estradiol transdermal patch. Materials and Methods: A total number of 90 patients were scheduled for FET. In the study group (n=45), 17-B estradi...

In this investigation, serum steroid hormones such as testosterone (T), 17β-estradiol (E2) and progesterone (P) in 12 female of the migratory population of Common carp (Cyprinus carpio) in southeast of Caspian Sea during a year from May 2011 to May 2012 were studied. The results of present study revealed that changes in levels of steroid hormones, (E2) and (T) were closely correlated to ovarian...

The adsorption properties and mechanics of selected endocrine disrupting compounds; 17 β-estradiol, 17 α – ethinylestradiol and bisphenol A on locally available black tea leaves waste and granular activated carbon were investigated. The results obtained indicated that the kinetics of adsorption were pH, adsorbent dose, contact time and temperature dependent with equilibrium being reached at 20 ...

The proton-coupled amino acid transporter, PAT1, is known to be responsible for intestinal absorption drug substances such as gaboxadol and vigabatrin. aim of the present study was investigate, if 17-α-ethinyl-estradiol (E-E2) 17-β-estradiol (E) inhibit PAT1-mediated proline taurine in vitro Caco-2 cells vivo using Sprague-Dawley rats assess potential taurine-drug interactions. E E-E2 inhibited...

the most important characteristics of ptsd, as an anxiety disorder, are memory disorders and hippocampus is one of the essential structures which plays a critical role in ptsd memory disorders. traumatic events cause apoptosis and alter the expression of neurotrophic factors in hippocampus. the aim of this study is to evaluate the effects of β-estradiol on behavioral responses in ptsd and to st...

The bone morphogenetic protein-2 (BMP-2) has been implicated in follicle growth and steroidogenic functions of the ovary. The BMP-2 belongs to the BMPs subfamily of TGF-β super family. The present study was carried out in sheep granulosa cell culture to study the effect of different doses of BMP-2 0ng/ml (control group), 30ng/ml, 50ng/ml and 100ng/ml on granulosa cell steriodogenic function. Fo...
