The accumulation, elimination and effect of heavy metals on plasma cortisol levels in Oreochromis sp. were studied in the exposure and recovery phases. In the exposure phase, the mean rate of accumulation in the tissues was in the order gill > liver > muscle for Pb exposure and muscle > liver > gill for As exposure. In the recovery phase, the order of elimination in the tissues was gill > liver > muscle for Pb and liver > gill > muscle for As. The amount of cortisol secreted by the Oreochromis sp...

REVIEW
F Guerrero Pérez, A P Marengo, C Villabona Artero
Glucocorticoid (GC) therapy is the most common cause of adrenal insufficiency (AI). The real prevalence of AI after GC is unknown but it could involve more than 30% of patients. Some gene variation has been associated with the variability of hypothalamic-pituitary-adrenal (HPA) axis and this issue could contribute to the individual variation of adrenal function after GC treatment. Symptoms and signs of AI are nonspecific and frequently the diagnosis is delayed. Dosage, duration of treatment, administration route and serum cortisol value are not completely useful to predict AI...

BACKGROUND: Silent corticotroph adenomas (SCAs) are characterized by strong ACTH immunostaining without clinical manifestations of hypercortisolism. Patients with SCAs often present with mechanical symptoms related to tumor growth. This study investigates the hypothalamic pituitary adrenal axis (HPA) characteristics after adenomectomy in patients with SCAs. METHODS: Biochemical parameters of HPA function were monitored frequently after surgical resection of non-functioning macroadenomas...

Early adversity such as depressed maternal care can have long-term physiological and behavioral effects on offspring and future generations. Exposure to chronic social stress (CSS), an ethologically model of postpartum depression and anxiety, during lactation impairs maternal care and exerts similar effects on the F1 dam offspring of the stressed F0 dams. These changes associate with increased corticosterone and neuroendocrine alterations. CSS F2 offspring further display decreased social behavior as juveniles and adults and decreased basal levels of corticosterone...

This study examined the effect of playing matches against different opponent teams (hard match; HM, medium match; MM, and easy match; EM) on pre-match testosterone concentration (T), pre-to-post match cortisol (C) concentration, and pre-competitive anxiety (CSAI-2 questionnaire) in 20 elite male basketball players. One training session (TS) was also assessed (control condition). Saliva steroids were determined by ELISA. The pre-T concentration was significantly lower for the TS (163±54pmolL(-1)), compared to the three official matches (EM: 208±82pmolL(-1), MM: 213±57pmolL(-1), and HM: 218±37pmolL(-1)) (p<0...

Thirty-five women participating in one or more intramural flag-football games provided saliva samples before, immediately after, and 10min after competition and completed an after-competition questionnaire appraising their own performance during the game. As seen in other studies of elite athletes, these recreational athletes, on average, showed significant elevations in testosterone (T) and cortisol (C) across the competition period - the "competition effect". In winners and losers, T levels at all time points measured were positively related to athletes' appraisals of their own individual performance...

Circulating microRNAs (c-miRNAs) in human plasma have been described as a potential marker of exercise. The present study investigated the effects of three acute resistance training (RT) protocols on the time-course changes of the c-miRNAs profiles in young males. The subjects (n = 45) were randomly divided into three groups: muscular strength endurance (SE), muscular hypertrophy (MH) and maximum strength (MS). Venous blood samples were obtained before exercise and immediately, 1 h and 24 h after each RT protocol to assess the following biological parameters: c-miRNAs, anabolic and catabolic hormones, inflammatory cytokines and muscle damage markers...

BACKGROUND: Animal models show that prenatal bisphenol A (BPA) exposure leads to sexually dimorphic disruption of the neuroendocrine system in offspring, including the hypothalamic-pituitary-adrenal (HPA) neuroendocrine system, but human data are lacking. In humans, prenatal BPA exposure is associated with sex-specific behavioural problems in children, and HPA axis dysregulation may be a biological mechanism. The objective of the current study was to examine sex differences in associations between prenatal maternal urinary BPA concentration and HPA axis function in 3 month old infants...

Cytochrome P450 (CYP) 3A is an important drug-metabolizing enzyme in humans. Assessing CYP3A activity is necessary for predicting therapeutic outcomes or the potential adverse events of various therapeutics. This study sought to evaluate the distribution of endogenous and exogenous markers reflecting hepatic CYP3A activity and related factors affecting its activity in healthy male and female. Each subject was given a single 1 mg dose of midazolam intravenously. Pharmacokinetics, pharmacometabolomics, and pharmacogenomics analyses were performed to evaluate CYP3A activity...

CONTEXT: Premenopausal women have blunted counter-regulatory hormone responses (CRR) to hypoglycemia compared to men. Postmenopausal women have CRR similar to men; the premenopausal pattern can be restored by estrogen. However, glucagon and pancreatic polypeptide (PP) responses remain lower in postmenopausal women than in men. Since hyperandrogenemia contributes to the metabolic phenotype of polycystic ovary syndrome (PCOS), we hypothesize that CRR to hypoglycemia especially of glucagon and PP is exaggerated in premenopausal women with PCOS compared to premenopausal control women...

BACKGROUND: Stress biomarkers have been linked to health and well-being. There are, however, few studies on how dysregulation in the hypothalamic-pituitary-adrenal axis and sympathetic nervous system actually affects functional health of family caregivers of persons with dementia. Further, it is not clear whether and how factors affecting caregiving stressor exposures such as care transitions and adult day services (ADS) use may affect such association. OBJECTIVE: First, to examine the association of daily stress biomarkers and functional health over time among family caregivers of persons with dementia...

Posttraumatic stress disorder (PTSD) is associated with increased risk for Type 2 diabetes and cardiovascular disease (cardiometabolic disease), warranting research into targeted prevention strategies. In the present case-control study of 160 young (mean age 32.7 years) male military veterans, we aimed to assess whether PTSD status predicted increased markers of cardiometabolic risk in otherwise healthy individuals, and further, to explore biological pathways between PTSD and these increased markers of cardiometabolic risk...

INTRODUCTION: Psychological stress is known to cause exacerbation of different skin pathologies including alopecia areata (AA). A hyperactivity of the HPA axis in patients affected by AA (AA-patients) was proposed to be a neuroendocrine response to stress. Still little is known about MSH and cortisol production in AA settings. AIM: The aim of the study was to compare trends in a production of melanocyte-stimulating hormone (MSH) and cortisol in patients with AA-patients and healthy controls...
