|
| Most of the activities of estradiol appear to be exerted via binding to specific estrogen receptors in target cells of tissue. |
|
| The estradiol valerate breaks down in the intestines and is converted to natural oestrogen, oestradiol. |
|
| However, a significant portion of testosterone in adolescent boys is converted to estradiol. |
|
| In contrast, most of the defeminization and masculinization of the CNS is dependent on conversion of testosterone to estradiol. |
|
| Salivary samples were collected before each exercise session to determine estradiol and cortisol concentrations and after each exercise session to determine cortisol concentrations. |
|
| Qlaira contains estradiol valerate and a gestagen known as dienogest. |
|
| A use according to any preceding claim in which the estrogen is selected from estradiol, estradiol-17ß, estradiol valerate and conjugated equine estrogens. |
|
| As a minimum, for proper diagnosis of perimenopause, menopause and hormone imbalances, the following tests should be done: blood levels of FSH, estradiol and testosterone. |
|
| Estrogens that have been used in oral contraceptives include estranol, which has about the same potency as estradiol, and mestranol, which is less potent. |
|
| Their activity is, however, much lower than that of estradiol. |
|
| Metabolism: Exogenously-derived or endogenously-derived estrogens are primarily metabolized in the liver to estrone and estradiol, which are also found in the systemic circulation. |
|
| Preliminary results show that there is a strong relationship to the amount of estradiol in the blood and performance on memory tests,' she explained. |
|
| The dose-response to genistein was similar to estradiol and tamoxifen. |
|
| This keratinization process is dependent on the endogenous estradiol secreted between the evening of diestrus 2 and that of proestrus. |
|
| What's more, a dose of estradiol or prostaglandin E2 just after birth caused female animals to produce the male number of active microglia. |
|
| Comparative estrogenicity of estradiol, ethynyl estradiol and diethylstilbestrol in an in vivo, male sheepshead minnow, vitellogenin bioassay. |
|
| The hormone that dominates female development is an estrogen called estradiol. |
|
| The main steroid hormones, testosterone, estradiol, and progesterone as well as prolactin play important physiological functions in puberty. |
|
|
|
| Gonadal steroidgenesis in girls starts with production of testosterone which is typically quickly converted to estradiol inside the ovaries. |
|
| Effect of estradiol administration on splanchnic perfusion after trauma-hemorrhage and sepsis. |
|
| The nonscrotal patches produce normal levels of dihydrotestosterone and estradiol. |
|
| To prove the cytotoxic efficacy of P estradiol in Jurkat T-cell model, cell viability was determined by the MTT assay. |
|
| Half of the men received the aromatase inhibitor anastrozole in addition, which created estradiol deficiency. |
|
| The researchers gave half the birds tiny implants that released estradiol, which normally abounds in females during breeding season. |
|
| The second study focused on this response following injection of estradiol and bisphenol A, alone and in combination, into rat cerebella. |
|
| Osteocalcin, Osteonectin, crosslaps, Serum estradiol and progesterone were measured using ADVIA Centaur automated competitive chemiluminescence immunoassay. |
|
| Manson, who says some studies suggest similar increased risks of heart disease and breast cancer with 17-beta estradiol, the type found in most estradiol therapy preparations. |
|
| Cadmium chloride, they have found, will promote growth of the MCF-7 human breast cancer cell line, cells that are normally amitotic in the absence of estradiol. |
|
| The conversion of testosterone to estradiol depends on the amount of body fat and estradiol levels in boys are typically much lower than in girls. |
|
| While testosterone is produced, all boys' changes are characterized as virilization, a substantial product of testosterone metabolism in males is estradiol. |
|
| Aside from toxic effects, when ingested some of these affect animal brain cells similarly to estradiol, causing hormone disruption in the affected wildlife. |
|
| We measured serum estradiol, testosterone, progesterone, SHBG, prolactin, FSH, and LH concentrations on the Abbott Architect i2000SR system using chemiluminescence. |
|
| In adjusted models, hs-CRP was significantly associated both with estradiol across the menstrual cycle and with progesterone during the luteal phase. |
|
| The classic AAS is testosterone, which is metabolized into the active metabolites of dihydrotestosterone, androstanolone, estradiol, androsterone, and androstenedione. |
|
| Estradiol and bisphenol A stimulate androgen receptor and estrogen receptor gene expression in fetal mouse prostate mesenchyme cells. |
|
| Estradiol together with other ovarian steroids also cause the darker coloration of the areola. |
|
| Estradiol levels rise earlier and reach higher levels in women than in men. |
|
| Estradiol mediates the growth spurt, bone maturation, and epiphyseal closure in boys just as in girls. |
