Estrogen replacement therapy (ERT) seems to enhance longevity in women. Both gender and aging have been shown to influence the regulation of circadian rhythms, yet little is known about the effect of ERT on circadian regulation. The aim of this study

Using high intensity venous sampling (1-2 min integrated intervals) we have observed rapid (< 10 min) large amplitude (up to 80 pg/ml) fluctuations in plasma ACTH concentrations in addition to variations at longer time scales. We developed a mathemat

Dysregulation of the hypothalamic-pituitary-adrenocortical axis has been theoretically linked to the processes of aging for decades. To investigate the effects of age on high frequency rhythms of plasma ACTH at the time of circadian activation, integ

This study was undertaken to examine whether several of the hormones that can be released by activation of serotonin receptors will be affected by long-term cocaine administration. Male rats received cocaine injections (15 mg/kg, IP) twice daily for

The effect of long-term pretreatment with cocaine on serotonergic regulation of ACTH (adrenocorticotropic hormone; corticotropin) and secretion of corticosterone in rats was investigated. The following observations were made: (1) Pretreatment with co

Insulin-induced hypoglycemia is a metabolic stress that stimulates secretion of adrenocorticotropic hormone (ACTH) and cortisol in a number of animal species. Dexamethasone is a potent synthetic glucocorticoid that suppresses the secretion of ACTH an

Time series of plasma ACTH concentrations were analyzed with a high resolution spectral analysis program based on digital Fourier transforms. Both coherent signal and stochastic aspects of the time series were analyzed. Samples were collected at 2- a

ACTH, like other anterior pituitary peptide hormones, is secreted episodically and demonstrates both circadian and ultradian rhythms. CRH is the major regulator of ACTH release from the pituitary corticotroph. To determine the dependence of ACTH ultr

Compared to younger rats, old rats exhibit prolonged elevations of plasma ACTH and corticosterone (CORT) in response to stress. In addition, CORT crosses the placenta. To investigate whether fetuses of older rats may be exposed to higher concentratio
