Estradiol regulation of uterine nucleolar estradiol binding sites
Biochimica et Biophysica Acta (BBA) - General Subjects, 1986Rat uterine nuclei contain two types of estrogen binding sites (I and II). Type I is the classical high-affinity, low-capacity binding component, while Type II has lower affinity and higher capacity. Investigation of the presence and number of estrogen-binding proteins in isolated uterine nucleoli, and the possible role of the estrogen-binding protein ...

Fertility and Sterility, 1988
Serum estradiol (E2) levels were measured in 451 men attending an infertility clinic and 80 fertile men attending for vasectomy. The normal range of E2 levels found in fertile men was 70 to 200 pmol/l. Subfertile men had lower mean E2 levels than fertile men (P less than 0.05), but there was no relationship to obesity, cigarette smoking, age, or the ...

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.

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 ...

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).

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.
