Serum estrogen concentration of rats fed soy protein diet and subjected to 20% energy restriction
… energy intake of C-AL and SPIAL, respectively. Serum estradiol concentration of these rats was determined at the end of feeding period and no significant differences were detected among the four groups. However, the 20% energy restricted groups had 77%-88% of serum estradiol concentration of …

Potential for osteoporosis in selected dancers
Eating attitudes, serum estradiol concentration, and bone mineral density were determined for 24 contemporary college dancers and 32 nonexercising control subjects. All subjects were nonsmoking, white females, not currently taking prescribed medication and had no prior eating disorders. Data were …

Progestin regulation of follicular dynamics in beef cattle
… wave and maximum follicle diameter) and serum concentrations of progesterone (P4) in beef cattle treated with a new or previously used CIDR. Serum concentrations of P4 for heifers in the New and Used CIDR groups were similar (P [greater than] 0.1) throughout the 14 d treatment period but …

The effect of boron supplementation and oral contraceptives on mineral status and hormone status of college female athletes and non-atheletes
… Body fat, height, bone mineral density, and serum calcitonin and parathyroid also were baseline measurements. Subjects were measured at baseline and six months for the following: dietary intake, body weight, serum levels of 17-f-estradiol, progesterone, and testosterone, and plasma and urine …

Artificial Induction of Lactation in Nonbreeder Dairy Cows
… was 32 kg/d and 20 kg/d, respectively. Mean serum and milk progesterone concentrations for samples collected during the first 6 d of lactation were not different between lactation-induced and nontreated cows. However, mean serum estradiol concentrations for induced cows were higher (P <0.05) …

The role of the thymus in the enhancement of humoral immunity by estrogen
… fashion. The four-day injection regimen of estradiol exposure, which replicates the levels and profile of serum estradiol of the rat estrous cycle, exerted a greater immunoenhancing influence than the chronic estradiol implant treatment. The cyclic regimen of estrogen replacement was used to …

Role of the ARF Tumor Suppressor in Osteoclasts
… Finally, we found that Cathepsin K loss enhances serum estradiol levels. Together, this data suggests that Cathepsin K-driven Cre will not consistently result in OC-specific gene loss and may lead to misinterpretation of phenotypes generated to study the function of OC genes. In parallel, we have …

Clinical and endocrine responses to ovarian hyperstimulation in flare and and luteal gonadotropin-releasing hormone agonist (GnRHa) protocols
… age, weight, and indication for IVF/ICSI. Serial serum Estradiol (E₂) levels and follicle data were obtained from the clinic chart. Follicle stimulating hormone (FSH), Luteinizing Hormone (LH), progesterone (P), androstenedione (D₄) and AMH levels were measured from aliquots of frozen serum …

Effects of Preovulatory Estradiol Concentration on Embryo Survival and Pregnancy Establishment in Beef Cows
<p>Estradiol exposure during the preovulatory period has been shown to affect the establishment and maintenance of pregnancy in beef cows. The mechanism by which estradiol affects pregnancy establishment and maintenance has not been well characterized. Previous studies have examined the effects of …

Biological Activity of Phenolics in Chicks and Rats
… lipid, cytochrome b(,5), cytochrome P-450, serum estradiol, egg weight and egg specific gravity were similar for laying hens fed 6% indulin, 6% arenaceous flour or 0% fiber control diets. Rats fed 6 or 12% indulin had similar hepatic lipid levels compared with controls. Rats fed 0.5% …

Effects of prenatal androgenization on hormones of growth and reproduction in cattle
… the effects of prenatal androgenization on serum concentrations of hormones that regulate growth and reproductive processes in cattle. In Experiment 1, the efficacy of Synovex$\sp\circler$H as an agent for prenatal androgenization was evaluated in 15 pregnant beef heifers. Fifteen additional …

Effects of a superovulatory dose of pregnant mare’s serum gonadotropin on uterine morphology, carbohydrate histochemistry and serum steroids in immature rates
… a physiological (4 IU) dose of pregnant mare's serum gonadotropin (PMSG) on the morphology of the endometrium and the carbohydrate composition of the uterine glycocalyx and secretions in immature rats and in untreated mature rats. The morphological and carbohydrate histochemical changes found …

Interaction of ACTH and Estradiol in the Regulation of Growth, Differentiation, and Steroidogenic Maturation of the Baboon Fetal Adrenal Gland
… suppressed maternal and fetal peripheral serum estradiol to less than 2% of control levels, and enhanced (P< 0.05) fetal adrenal weight by 75% but decreased fetal cortical cell size. In contrast, the intensity and immunoexpression of P450c17 was enhanced and present in virtually all cells. …

The aryl hydrocarbon receptor signaling pathway and adverse reproductive outcomes
… body mass index, smoking status, and low estradiol levels may increase the risk of experiencing these debilitating menopausal symptoms. However, these risk factors do not fully explain why women have hot flashes and sleep disturbances and why these symptoms vary between and within women. …

Sex differences in human perinatal development and autism
… Steroid hormone levels were assessed in maternal serum. Estradiol levels correlated with both maternal autistic traits and the male infants’ autistic traits, but there was no correlation with female infants’ autistic traits. Study 3 (described in Chapter 4) reports a large prospective cohort study …

Monitoring and improving reproductive performance of crossbred dairy cattle in Tigray Region, Ethiopia
… on-farm diagnostic tools to determine milk and serum progesterone (P4) and evaluate reproductive status. There were 177 dairy farms (range 1-115 cattle per farm) included in the questionnaire survey. Of these, 47 participated in the quantitative determination of P4 and estradiol profiles that …

Ecology and physiology of a black bear (Ursus americanus) population in the Great Dismal Swamp and reproduction physiology in the captive female black bear
… spring and late fall and at a low during summer. Serum creatinine concentrations also varied seasonally (<u>P</u><0.001), with a peak during denning and high levels in spring and late fall, perhaps resulting from transition from and to hibernation. A urea/creatinine (U/C) ratio ≤10 was not a good …

Determining the role of nerve growth factor-beta in seminal plasma on bovine reproduction
… There were no differences in progesterone or estradiol production between treatments. Follicle tissue treated with NGF had upregulated steroidogenic enzyme 17-beta-hydroxysteroid dehydrogenase (17β-hsd) gene expression and downregulated fibroblast growth factor 2 (Fgf2) gene expression. …
