in the religion of islam, fasting is obligatory for healthy adults during ramadan. millions of muslims around the world practice fasting in this holy month which may cause different metabolic and hormonal changes due to the restrictions in regular caloric intake. this article was aimed to review some possible effects of ramadan fasting on the endocrine system which has a great impact on physiol...

The Metabolic syndrome is a modern epidemic and is considrred to be one of the major public health issues of this century. It is constellation of physical conditions and metabolic abnormalities commonly found in association with increased risk for development of Type II diabetes mellitus, cardiovascular disease and other medical conditions. Thyroid hormones play an important role in regulating ...

This study was designed to evaluate vitamin D3 and metabolic hormones in hypothyroidism with syndrome without syndrome. Sixty patients were divided into three groups, 30 syndrome, healthy controls compared the patients. There a significant increase tetraiodothyronine, free thyronine very thyroid stimulating hormone women A systolic blood pressure, body mass index, fasting glucose, glycosylated ...

The steroidal nature of adrenocortical hormones was established in 1937, when Reichstein synthesized desoxycorticosterone. Eventually it was clearly established that the adrenal cortex elaborated a number of hormones and that these compounds differed in their amount of inherent metabolic (glucocorticoid) and electrolyte regulating (mineralocorticoid) activity. The actions of these hormones exte...

The physiological mechanisms that control energy balance are reciprocally linked to those that control reproduction, and together, these mechanisms optimize reproductive success under fluctuating metabolic conditions. Thus, it is difficult to understand the physiology of energy balance without understanding its link to reproductive success. The metabolic sensory stimuli, hormonal mediators and ...

Background:The current study aimed at evaluating the association between thyroid-stimulating hormone (TSH) level in upper normal limits with metabolic syndrome, modifiable risk factor for cardiovascular disease, and its components according to Adult Treatment Panel III of National Cholesterol Education Program. Methods</...

The dramatic rise in the prevalence of obesity and type 2 diabetes mellitus (T2DM) has become a major global public health issue. There is increasing evidence that metabolic surgery is more effective than diet and exercise for diabetes remission and weight loss. Moreover, the rapid time course and disproportional degree of T2DM improvement after metabolic procedures compared with equivalent wei...

One hundred and eighty (180) day-old broiler chickens were used to investigate the effects of dehydroepiandrosterone (DHEA) on growth performance, carcass composition, and the serum concentrations of several lipid metabolic hormones and metabolic parameters (indicators). The broilers received the same basal diets, with DHEA added at 0 (control), 5 and 20 mg/kg feed. During the experimental peri...

BACKGROUND Because of the substantial energy demands of reproduction, the brain must temper the fertility of individuals to match nutritional availability. Under-nutrition is associated with infertility in humans and animals. The brain uses adipose- and gut-derived hormones, such as leptin, insulin and ghrelin, to modulate the activity of the GnRH neuronal network that drives reproduction. It i...
