Once secreted into theblood, estrogens bind reversibly to aproteinknown as sex hormone-bindingglobulin. Thus, some of thehormoneinserumis bound and some is free, or unbound. At its target tissues, the free hormone penetrates thecellsurface and then binds to a protein known as an estrogenrecept...
It is thus biologically plausible that an amenorrhea-associated decline in estrogen may be associated with cognitive impairment in AN, while the return of menses and therefore normal circulating serum estrogen levels may contribute to the ... HT Chui,B Christensen,RB Zipursky,... - 《Journal of...

Normal serum levels of estradiol are between 70 and 110 pM during diestrus and between 350 and 730 pM during estrus of the female mouse estrous cycle57. Thus, the estradiol treatment in this study likely resulted in levels comparable to what is experienced during estrus. Further, the dose of...
Constant infusions of 3 H-androgen/ 14 C-estrogen were given to 18 men with increased serum bilirubin concentrations and biopsy proven hepatic cirrhosis. From data obtained from the infusions and the radioimmunoassay of circulating endogenous steroid levels metabolic clearance rates (MCR), blood product...
The mean serum E2 concentration (41.8±6.0 pg/ml) was only 35% that of normal follicular phase E2 levels. The mean serum SHBG concentration of hirsute patients was 40% that of normal women and their mean unbound unconjugated E2 and T were 130% and 160%, repectively, of normal. Despite...
Methods Chemiluminescence,immunohistochemistry and Western blot technique were carried out to detect the serum level of sexual homones and determine the distribution and expression of ERβ in the colons of the STC rats and normal control rats,respectively. Results Chemiluminescence showed that all the ...
Changes in serum estradiol, insulin-like growth factor-1, leuteinizing and testosterone levels, and leuteinizing hormone-stimulated testosterone production per testis in vitro from hatching to adulthood were studied in Korean native chickens of 1, 2, 4, 6, 8, 10, 12, 14, 16, 18, 21, 24...

Gonadal intact S122A male mice have normal sex steroid levels and a normal skeleton, but decreased body weight In young adult gonadal intact mice, there was no difference between S122A and WT mice in the mRNA expression level of ERα measured in cortical bone (Table 1). Serum levels of te...
