Although the ovaries produce majority of estrogens in women before menopause, estrogen is also synthesized peripheral tissues such as adipose tissue (AT). The typical female AT distribution, concentrated subcutaneous and femoro-gluteal regions, estrogen-mediated, but significance synthesis premenopausal poorly understood. Serum visceral homogenates from 28 undergoing non-malignant surgery were ...

We describe the preparation of [2,4,16,16-2H4]estradiol-17 beta. The method for quantitative determination of subpicomole amounts of estradiol-17 beta (trimethylsilyl ether derivatives) by gas-liquid chromatography-mass spectrometry with multiple ion detector and with [2H4]estradiol-17 beta as the carrier is presented and characterized. Values for serum samples, as measured by radioimmunoassay ...

Cell lines were established from the MtTF4 tumor, growth of which is inhibited by estradiol, in order to determine whether the effect observed in vivo was due to a direct action on tumor cells. Two different cell lines were obtained according to the medium in which tumor cells were dispersed and cultured. The F4P cells were obtained when the culture medium contained charcoal-treated fetal calf ...

The hormonal derivatives diethylstilbestrol, hexestrol, dienestrol, cortisone, estradiol-17a, estradiol-17/3, progesterone, and phloretin were compared with regard to their capacity to enhance carcinostasis in the presence of the niacin antagonist 6aminonicotinamide. Diethylstilbestrol and hexestrol were found to be more powerful than either estradiol-17/îor dienestrol. Phloretin, estradiol-17...

OBJECTIVE To compare the effects of continuous 17-beta estradiol-only silastic implants with those of continuous 17-beta estradiol plus continuous nomegestrol acetate silastic implants on symptom control, lipid profile and tolerability in postmenopausal women. METHODS This was an open-label, parallel-group study. Women with and without uterus and no contraindications to hormone therapy (HT) i...

Background and Purpose—Neurocognitive dysfunction is an important source of patient morbidity and mortality after cardiac surgery that may disproportionately affect postmenopausal women. 17 -Estradiol limits the extent of ischemic neuronal injury in a variety of experimental models. The purpose of this study was to evaluate whether perioperative administration of 17 -estradiol to postmenopausal...

A sequential radioimmunoassay procedure for unconjugated and conjugated estrone, estradiol-17 beta and estriol in male human plasma was developed. The blank values in this assay for unconjugated estrone, estradiol-17 beta, estriol conjugated estrone, estradiol-17 beta and conjugated estriol were 0.36 +/- 1.14 pg, 3.90 +/- 2.75 pg, 2.25 +/- 2.08 pg, 0.92 +/- 1.51 pg, 5.02 +/- 2.86 pg and 3.12 +/...

Effects of the combined injection with progesterone and estradiol-17 (3 i.m. on the accumulation of the superficial pigment of the eggshell in the quail shell gland were investigated. Arninoglutethimide (AG, 20rng/100g BW) was administered s.c. to quail hens 10 h before the expected ovulation, followed by the administration of progesterone (0.1 rng/100 g BW) and estradiol-17 {1 (0.1 rng/100g BW...
