the overtraining syndrome (ots) is a physically debilitating medical condition that results in athletes being totally compromised in their capacity to perform and compete. many physiological systems are affected by the process of overtraining and the development of the ots which results from it; but one system in particular, the immune, is highly susceptible to degradation resulting in a reduct...

background: since the introduction of the first radioimmunoassay, several improvements have been made in the design of immunoassays such as method of antibody production, labeling, automation and detection technology. we performed an analytical evaluation of the new electrochemiluminescent immunoassay (eclia) for serum tsh, ft4 and t3 in the elecsys 2010 immunoassay system and compared the resu...

this study was conducted to investigate the effect of ascites-related physiological and metabolic parameters in broiler chickens fed with different components of bentonite. two hundred and seven days old arian male chicks were allocated into five dietary treatment groups including 1) basal diet (control); 2) basal diet + 1% sulphated sodium bentonite (ssb); 3) basal diet + 1% non-processed sodi...

introduction: muslims fast from dawn to dusk during ramadan. the effects of prolonged food deprivation on endocrine hormones have been studied in healthy adults but no previous study has investigated this effect on children. this study aimed to evaluate the feasible changes in serum level of thyroxin (t3), tetraiodothyronin (t4), thyroid stimulating hormone (tsh) and body composition in pre-men...

thyroid hormones (t3, t4) have marked effect on body metabolism and in controlling osmoregulation activity in fish. the aim of this study was to determine the effect of water salinity changes on thyroid hormones level and thyroid-stimulating hormone (tsh) of grass carp. for this purpose 120 grass carp were divided randomly in to four groups (10 fish in each group and three replicates per treatm...

background: asparagus is a plant with high nutritional, pharmaceutical, and industrial values. objective: the present study aimed to evaluate the effect of aqueous extract of asparagus roots on the hypothalamic-pituitary-gonadal axis hormones and oogenesis in female rats. materials and methods: in this experimental study, 40 adult female wistar rats were divided into five groups, which consist ...

background: sodium arsenite and/ or vasectomy may cause variation in sex hormones which affect pathophysiology of reproductive organs. objective: the aim was to investigate the morphological changes in structure of testis and hormonal imbalance in bilateral vasectomised rats treated with sodium arsenite. materials and methods: four groups of rats: bilateral vasectomy + sodium arsenite, bilatera...

conclusions it seems that noise pollution has harmful effects on the fertility of males. also these findings may suggest the use of a natural curative approach rather than pharmaceutical drugs to optimize both neuroendocrine gonadal axis and testicular integrity induced by pathogenesis stress, and enhance fertility capacity in men. background this study was conducted to examine the efficacy of ...

Background: Much research has widely been conducted into thyroid hormones levels following radiotherapy for breast cancer. Consequently, in this study, we evaluated to relate the rate of thyroid hormones levels with the dose distribution among breast cancer patients.Material and Methods: Thirty patients were treated with 4-field breast cancer radiotherapy. The dose volume histograms, the volume...
