A new multidisciplinary synthetic approach comprising polymer-support synthesis, microwave-assisted synthesis, and multicomponent condensation facilitates synthesis of triaza-fluorenes library with a set of advantages such as rapid process, simple purification, and structural diversity in one shot. Microwave-assisted multistep synthetic protocol was used to(More)
BACKGROUND To assess parameters of 3-dimensional power Doppler ultrasound in differentiating an endometrioma from other hypoechogenic adnexal cysts. METHODS We collected 58 patients with classic-appearing endometriomas (homogeneous hypoechogenic adnexal cysts with round shapes) on a 2-dimensional conventional sonography. The serum level of CA-125,(More)
Diversity-oriented synthesis of novel benzimidazole linked indolo-benzodiazepine/quinoxaline ring systems using poly(ethylene glycol) as soluble polymer support is described. Commercially available 4-fluoro-3-nitrobenzoic acid and indoline were utilized for the construction of these annulated biheterocyclic compound libraries having multiple privileged(More)
BACKGROUND The endometrium becomes receptive to the embryo after sequential actions of estrogen and progesterone. The purpose of this study was to examine the effects of estrogen and progesterone on endometrial hemodynamics and on secretion of vascular endothelial growth factor (VEGF) from endometrial epithelial cells (EEC). METHODS Six early(More)
