Attachment behaviors play a critical role in regulating emotion within the context of close relationships, and attachment theory is currently used to inform evidence-based practice in the areas of adolescent health and social care. This study investigated the association between female adolescents' interview-based attachment behaviors and two markers of hypothalamic-pituitary-adrenal axis activ...
Dehydroepiandrosterone and dehydroepiandrosterone sulfate are en dogenous steroids largely produced in the adrenal cortex and excreted in the urine. Many studies have demonstrated that administration of dehy droepiandrosterone to animals protects against a variety of chemical carcinogens. Kpidemiological studies suggest that the circulating levels of these steroids in humans are related to the ...
BACKGROUND Animal studies have shown that neuroactive steroids modulate the activity of the gamma-aminobutyric acid type A/benzodiazepine receptor complex and that these steroids display anxiolytic or anxiogenic activity depending on their positive (e.g. allopregnanolone) or negative allosteric modulation (e.g. dehydroepiandrosterone sulphate) of this receptor. This study compared plasma levels...
OBJECTIVE Dehydroepiandrosterone sulphate (DHEA-s) is an anabolic protective hormone of importance for maintenance of health. DHEA-s levels peak in young adults and decline thereafter with age. DHEA-s has previously been shown to be lower in individuals reporting prolonged stress. This study investigates DHEA-s levels in patients with clinical burnout, a disorder caused by long-term psychosocia...
Background: Women suffer more often from depression than men. Social research suggests that high androgen levels cause aggressive behavior in men and women, and consequently cause depression. The purpose of this study was to determine serum levels of androgens, especially testosterone, in patients with depression. Material and methods: In this case-controlled study, we measured serum testoste...
Androgens have been implicated in increasing ovarian cancer risk; however, results from prospective studies have been inconclusive. The authors examined whether plasma concentrations of testosterone, androstenedione, dehydroepiandrosterone, and dehydroepiandrosterone sulfate were associated with risk of epithelial ovarian cancer in a nested-case control study, using data from three prospective ...
We evaluated the reproducibility of plasma hormone levels over time in 79 healthy postmenopausal women, ages 51-69 years at baseline, who were not using postmenopausal hormones. Three blood samples were collected between 1989 and 1992 from each of these women. We assessed plasma levels of estradiol, free estradiol, percentage of free estradiol, bioavailable estradiol, percentage of bioavailable...
