purpose: this study aimed to investigate the effect of one intensive training session on the changes of beta-endorphin and serum cortisol levels of elite wrestlers. methods: in this quasi-experimental research with one group and pretest-posttest design, 16 elite wrestlers within the age range of 18 to 25 years were purposefully and selected and they voluntarily participated in the research. the...

Background: The results of previous studies suggested that there is an increased risk of patent ductus arteriosus (PDA) in the neonates with lower serum cortisol levels. This study aimed to assess the association between serum cortisol values and PDA and investigate if there is an association between PDA and the antenatal administration of betamethasone. Methods: The present study was carried o...

background glucose is an essential element in the supply of body’s energy. in diseases such as diabetes, glucose increase is associated with disturbance in metabolism. cortisol is an important hormone in the regulation of glucose metabolism, and human serum albumin (hsa) is one of the most important glucose and cortisol transmitters in blood. interaction between albumin and these ligands could ...

  ABSTRACT In order to evaluate time course of changes in serum concentration of thyroid hormones, cortisol and ACTH in patients exposed to chemical weapons containing sulfur mustard, we measured serum concentrations of hormones on the first, third and fifth week following injury in 13 soldiers and compared them to the results obtained from 34 control men. Free T4 and T3 indices were decrease...

BACKGROUND The biologically active component of a hormone is the unbound or free fraction. Changes in cortisol-binding protein could give misleading results if only total cortisol is measured for the interpretation of dynamic function tests. METHODS This study aimed to measure serum free cortisol using a steady-state gel-filtration method and then to evaluate the correlation between the serum...

human serum albumin (hsa) is an important protein that carries variety of substances like some hormones and drugs in blood. pharmacological studies of the interaction of many drugs and hsa are reported during several decades, specially recently years. interaction of cortisol and fluoxetine hydrochloride (flx) (as a common anti-stress drug) with hsa (as their carrier in blood) has been studied s...

BACKGROUND In patients with hypoadrenalism, it is often difficult to assess the optimal dose of glucocorticoid replacement. Serial serum cortisol measurements for a cortisol day curve are sometimes used, but this has low acceptability for patients. In this study, we evaluate the reliability of saliva and capillary bloodspot cortisol as alternative methods in assessing cortisol profiles in hypoa...

Salivary cortisol reflects the free fraction of serum cortisol. Monitoring salivary cortisol may be a promising alternative method for assessing serum cortisol in some clinical situations. We aimed to compare the reliability of salivary vs. serum cortisol during ACTH test. 84 subjects (mean age 63.2; 24-89 years; n=66 males) suspected for adrenocortical insufficiency underwent an ACTH test. Pat...
