in teleosts the insulin-like growth factor-i, a member of igf system, play an important role in the control of growth and reproduction including metabolism, cell division, oogenesis, final oocyte maturation and secretory activity. this system is controlled by several hormones and metabolic status. serum igf-i, thyroxine (t4) and cortisol levels were studied in two female brood stocks (caught fr...
Cortisone acetate test was performed in twelve young adult patients with diabetes mellitus type 1, after dexamethasone administration to suppress endogenous cortisol production. Previous screening revealed that all of the subjects had peak cortisol responses in the range from subnormal to normal, as determined by a low-dose Synacthen test. The aim was to find out whether these patients would ex...
In the present study, we assessed the responses of the vasotocinergic and isotocinergic systems to chronic stress induced by cortisol administration in the gilthead sea bream (Sparus aurata). Pituitary and plasma arginine vasotocin (AVT) and isotocin (IT) levels, as well as hypothalamic pro-vasotocin (pro-VT) and pro-isotocin (pro-IT) mRNA expression levels, were analysed. In addition, the mRNA...
BACKGROUND Inhaled corticosteroids (ICS) are recommended in the treatment of asthmatic patients. They have been said to be efficacious in the treatment of asthma in respect to cortisol and bone metabolism. METHODS The effects of the two inhaled corticosteroid, budesonide (BUD) and fluticasone propionate (FP) on bone metabolism, morning cortisol and their effects on the clinical parameters (FE...
In human adrenarche during childhood, the secretion of dehydroepiandrosterone (DHEA) from the adrenal gland increases due to its increased synthesis and/or decreased metabolism. DHEA is synthesized by 17a-hydroxylase/17,20-lyase, and is metabolized by 3b-hydroxysteroid dehydrogenase type 2 (3bHSD2). In this study, the inhibition of purified human 3bHSD2 by the adrenal steroids, androstenedione,...
Lambs gain about 70 % of their birth weight in the last 6 weeks pregnancy. In this period, many physiological events occur ewe metabolism. The increase number fetuses also affects these events. aim study was to determine effect single and twin pregnancy on serum cortisol, glucose, triglyceride, HDL-cholesterol, total protein, cholesterol, calcium phosphorus levels at postpartum days. This condu...
In human adrenarche during childhood, the secretion of dehydroepiandrosterone (DHEA) from the adrenal gland increases due to its increased synthesis and/or decreased metabolism. DHEA is synthesized by 17α-hydroxylase/17,20-lyase, and is metabolized by 3β-hydroxysteroid dehydrogenase type 2 (3βHSD2). In this study, the inhibition of purified human 3βHSD2 by the adrenal steroids, androstenedione,...
026_7982_Reference values for leptin, cortisol, insulin and glucose, among European adolescents.indd
Background and Objective: Adequate concentrations of leptin, cortisol, and insulin are important for a suitable metabolism and development during adolescence. These hormones jointly with glucose play a major role in fat metabolism and development of childhood obesity. Our main objective was to quantify biomarkers as leptin, cortisol, insulin and glucose status in European adolescents to contrib...
During in vitro incubation, prolactin release is inhibited in a dose-related manner by cortisol. This action is mimicked by the synthetic glucocorticoid agonist dexamethasone but not by other steroids tested. Perifusion studies indicate that the inhibition of [3H]prolactin release by cortisol occurs within 20 min. Cortisol (50 nM) also inhibits cAMP accumulation and reduces 45Ca2+ accumulation ...
The glucocorticoid hormone cortisol is essential for many forms of regulatory physiology and for cognitive appraisal. Cortisol, while associated with fear and stress response, is also the hormone of energy metabolism and it coordinates behavioral adaptation to the environmental and internal conditions through the regulation of many neurotransmitters and neural circuits. Cortisol has diverse eff...
