Copper and the estradiol receptor
Biochemical and Biophysical Research Communications, 1987Copper is an essential element in living organisms and it appears to be involved in estrogen action. This study bears on the manner in which the metal may be linked to the mechanism of this action. Divalent copper was found to induce at 37 degrees C a several fold increase in estradiol binding to the receptors in rat uterine cytosols.

Aptamer-based optical biosensor for rapid and sensitive detection of 17β-estradiol in water samples.
Environmental Science and Technology, 2012Required routine monitoring of endocrine disrupting compounds (EDCs) in water samples, as posed by EPA Unregulated Contaminant Regulation (UCMR3), demands for cost-effective, reliable and sensitive EDC detection methods.

Estradiol-17β (E2) steroid hormone is produced mainly in the ovary, stimulates proliferation of the uterine endometrium, induces the LH surge for ovulation, and inhibits the pituitary hormone release via negative feedback. E2 is also produced in the testis but in low concentrations.

RADIOIMMUNOASSAY OF ESTRONE AND ESTRADIOL
Acta Endocrinologica, 1970ABSTRACT Antibodies to estradiol were produced by immunization of sheep with 17β-estradiol-succinyl-BSA. The antiserum cross reacted readily with estrone and was used for radioimmunoassay of plasma estrone and estradiol. The method includes ether extraction, separation of estrone and estradiol by Sephadex LH-20 column chromatography and radio ...

The degradation of three endocrine disrupting chemicals (EDCs), bisphenol A, ethinyl estradiol, and estradiol, was investigated via ultraviolet (UV) radiation photolysis and the UV/hydrogen peroxide advanced oxidation process (AOP).

Peptides, 2001
Estradiol has long been known to inhibit feeding in animals, but the mechanism(s) mediating its effects have not been clear. Demonstrations that estradiol's feeding effects are expressed as decreases in meal size coupled with the emerging consensus that cholecystokinin (CCK) released from the small intestines during meals is a physiological negative ...

Evaluating stereoselective sorption by soils of 17α-estradiol and 17β-estradiol
Chemosphere, 2011The application of manure and biosolids onto agricultural land has increased the risk of estrogenic exposure to aquatic systems. Both αE2 and βE2 have been routinely detected in surface and ground waters with higher concentrations reported near concentrated animal feeding operations and agricultural fields. Although movement through the soil to a water

Serum Levels of Estrone and Estradiol After Implantation of Estradiol Pellets
Southern Medical Journal, 1979Serum estrone, estradiol, progesterone, FSH, and LH levels were studied after the implantation of estradiol pellets in female volunteers in the reproductive age group. The estradiol pellets were implanted at six-month intervals. The first implant consisted of four pellets (25 mg each).

Label-free aptamer-based electrochemical impedance biosensor for 17β-estradiol.
In Analysis, 2012A novel aptamer-based label-free electrochemical impedance spectroscopy biosensor for 17β-estradiol has been fabricated. The aptamers were firstly immobilized on the gold electrode through Au-S interaction; the aptamer probe was then bound with the ...

Efficacy of transdermal estradiol
American Journal of Obstetrics and Gynecology, 1987Several side effects and risks associated with estrogen replacement therapy are known to stem from the hormone's impact on the liver. With oral administration, the enhanced action at hepatic, as compared with nonhepatic, sites is presumably related to the so-called first-pass effect.
