Estradiol In Females May Negate Skeletal Muscle Myostatin Mrna Expression And Serum Myostatin Propeptide Levels After Eccentric Muscle Contractions
Estrogen muscle damage eccentric contractions myostatin
2015/3/23
Eccentric contractions produce a significant degree of inflammation and muscle injury that may increase the expression of myostatin. Due to its anti- oxidant and anti-flammatory effects, circulating 1...

Background: The inherent shortcomings of conventional drug delivery systems containing estrogens and the potential of nanoparticles (NPs) have offered tremendous scope for investigation. Although poly...
Endogenous estradiol and testosterone may predispose toward atherogenic lipid profile, but higher blood level of testosterone is associated with lower number of stenoses in the coronary arteries of men with coronary disease
Endogenous estradiol testosterone may predispose toward atherogenic lipid profil coronary arteries men coronary disease
2009/4/20
Objectives: To assess the correlations between blood levels of sex steroid hormones and blood lipid profile or the degree of coronary artery stenosis in men with coronary artery disease (CAD). Metho...
Effects of long-term estradiol treatment on the contractile response to muscarine and muscarinic receptor subtypes in the bladder of aged female rats
long-term estradiol treatment contractile muscarine muscarinic receptor subtypes
2009/3/2
In this study, we tried to elucidate the effect of estrogen treatment on the detrusor contractile response to muscarine and muscarine receptor subtypes of the bladder in 13-month-old female Wistar r...
Estradiol and plasminogen activator secretion by cultured rat Sertoli cells in response to melanocyte-stimulating hormones
Estradiol and plasminogen activator secretion cultured rat Sertoli cells melanocyte-stimulating hormones
2009/2/23
Pro-opiomelanocortin-derived peptides, alpha-MSH and beta-endorphin, are synthesized and secreted by Leydig cells, and are believed to have paracrine effects on Sertoli cells in the testis. Peptid...
Endocrine parameters, hormone receptors, and functions of the testicular interstitium and seminiferous epithelium in estradiol-immunized Ile-de-France rams
gonadotropin secretion Leydig cells Sertoli cells FSH receptors androgen receptors
2009/2/23
The testicular response of Ile-de-France rams actively immunized against estradiol (E2) was evaluated during both the ovine nonbreeding season (spring) and breeding season (autumn). Plasma concentrati...
Follicle stimulating hormone, luteinizing hormone and testicular Leydig cell responses to estradiol immunization in Ile-de-France rams
Follicle stimulating hormone luteinizing hormone testicular Leydig cell estradiol immunization Ile-de-France rams
2009/2/23
Active immunization of Ile-de-France rams against estradiol (E2) resulted in the production of E2-neutralizing antibodies and an elevation in the plasma concentrations of FSH, LH, and testosterone...
Regulation of gonadotropin secretion in the male: effect of an aromatization inhibitor in estradiol-implanted, orchidectomized dogs
gonadotropins testosterone estradiol aromatase aminoglutethim
2009/2/23
Testosterone is aromatized to estradiol in both peripheral tissues and the central nervous system. Various authors have suggested that this conversion in the male may be prerequisite for the regulat...
Increased plasma and pituitary prolactin concentrations in adult male rats with selective elevation of FSH levels may be explained by reduced testosterone and increased estradiol production
Increased plasma pituitary prolactin concentrations adult male rats
2009/2/23
The roles of testosterone and estradiol in regulating prolactin concentrations were studied in acutely castrated adult male rats receiving subcutaneous Silastic implants of the sex steroids. Testost...
Cytoplasmic estradiol binding sites in testis of fertile and infertile men
estradiol receptors human testis receptor ontogenesis Leydig cell function human testicular disorders testicular cytosolic receptors
2009/2/20
Free cytoplasmic estradiol receptor was determined in testicular biopsies from six adults showing various primary testicular disorders, and in testicular tissue obtained at autopsy from 18 males of ...
Regulation of gonadotropin secretion in the male dog. Role of estradiol
gonadotropin secretion male dog
2009/2/19
Steroid regulation of pituitary LH and FSH secretion in the male may be mediated via the direct action of testosterone, or via the conversion of testosterone to either dihydrotestosterone (DHT) or e...
