The purpose of this study was to investigate the effect of 8 weeks resistance training with different intensity on leukocyte count, IgG, cortisol and lactate concentration in untrained men. 24 untrained male (aged 23.67±1.71 years; height 176.04±5.82 cm; weight 70.78±6.66 kg and body fat 15.82±2.47 percent) were selected and randomly divided into three groups: high-intensity (80%1RM)(n=8), low-...

In the current study, we explored how a person's physiological arousal relates to their performance in a challenging math situation as a function of individual differences in working memory (WM) capacity and math-anxiety. Participants completed demanding math problems before and after which salivary cortisol, an index of arousal, was measured. The performance of lower WM individuals did not dep...

Hair cortisol concentration differs across site and person: Localisation and consistency of responses to a brief pain stressor. 1 Hair cortisol responses Summary Although in vitro studies have shown that cortisol concentrations in human and animal hair respond to environmental stressors, few data have been reported regarding the in vivo variability of hair cortisol to brief pain stressors. As a...

Objective. The present study aimed at investigating unique patterns of salivary cortisol reactivity and recovery in response to a social stressor among girls with early puberty and exploring possible role of depressive symptom in this association. Design. Case-control study. Patients. Fifty-six girls with early puberty and age- and body mass index- (BMI-) matched normal puberty controls (n = 56...

Cortisol, 11-deoxycorticosterone, progesterone, 17 alpha-hydroxy-progesterone, 17 alpha-hydroxy-20 beta-dihydroprogesterone, or a combination of the last 2 steroids, were injected into different groups of immature female Epinephelus. None of the steroids tested had significant effects on serum electrolyte level, and hepatosomatic and gonadosomatic indices. Serum glucose concentration was elevat...

The aim of this study was to examine relationships among temperament, endocrinology, and reproductive parameters of bulls enrolled in an 84-day performance test. Angus bulls (n = 60) were housed in six pens grouped by age and weight. Pen scores (PS; 1 = docile to 5 = very aggressive) were assigned on Days -1, 27, 55, and 83 of the performance test. On the following day, blood and hair samples w...

The purpose of this study was to evaluate the effect of a forest environment on salivary cortisol concentration, particularly on the characteristics of its distribution. The participants were 348 young male subjects. The experimental sites were 34 forests and 34 urban areas across Japan. The subjects viewed the landscape (forest or urban environment) for a period of 15 min while sitting in a ch...

Introduction It is well known that pregnancy is associated with an increase in plasma cortisol and that especially in the third trimester the values attained resemble a state of adrenocortical hyperfunction (Kopelman & Levitz, 1970). It has also been shown that the concentration of cortisol in cord blood reflects the maternal state although it is less than the corresponding maternal values and ...

A 9-year-old male German shepherd dog was evaluated for clinical and clinico-pathological changes that were suggestive of Addison's disease. On further investigation the basal plasma cortisol concentration was high, a normal cortisol response to ACTH stimulation occurred, plasma renin activity was elevated and low serum aldosterone concentration was present. A diagnosis of hyperreninaemic hypoa...

INTRODUCTION Outcomes following bacterial meningitis are significantly improved by adjunctive treatment with corticosteroids. However, little is known about the levels and significance of intrathecal endogenous cortisol. The aim of this study was to assess cortisol as a biological and diagnostic marker in patients with bacterial meningitis. METHODS Forty-seven consecutive patients with bacter...
