Origin of ultradian pulsatility in the hypothalamic-pituitary-adrenal axis [PDF]

open access: yes, 2009
The hypothalamic-pituitary-adrenal (HPA) axis is a neuroendocrine system that regulates the circulating levels of vital glucocorticoid hormones. The activity of the HPA axis is characterized not only by a classic circadian rhythm but also by an ultradian

Effects of loperamide on the human hypothalamo-pituitary-adrenal axis in vivo and in vitro. [PDF]

open access: yes, 1992
Loperamide, an opiate agonist of high specificity for p-receptors, was recently reported to suppress ACTH and cortisol levels in normal subjects, but not in patients with proven ACTH-dependent Cushing’s disease. However, there is little information on

Induction of final oocyte maturation in Cyprinidae fish by hypothalamic factors: a review

open access: yesVeterinární Medicína, 2009
Gonadotropin-releasing hormone in Cyprinidae as in other Vertebrates functions as a brain signal which stimulates the secretion of luteinizing hormone from the pituitary gland. Two forms of gonadotropin-releasing hormone have been identified in cyprinids,

Inconsistent stimulation of plasma ACTH through corticotropin-releasing factor in a patient with central Cushing's disease due to pituitary adenoma [PDF]

open access: yes, 1985
Three uncommon findings were observed in a case of Cushing's disease due to macroadenoma: no suppression of plasma ACTH during an 8-mg dexamethasone test, a negative corticotropin-releasing factor test, and a normal X-ray of the sella turcica.

Antiapoptotic effects of velvet antler polypeptides on damaged neurons through the hypothalamic-pituitary-adrenal axis [PDF]

open access: yesJournal of Integrative Neuroscience, 2020
We investigated the effects of velvet antler polypeptide on cognitive impairment and the underlying mechanisms. Hydrogen peroxide-induced cell injury was used to establish an in vitro model of SH-SY5Y cells.

Crossover of the hypothalamic pituitary-adrenal/interrenal (HPA), -thyroid (HPT), and -gonadal (HPG) axes in testicular development

open access: yesFrontiers in Endocrinology, 2014
Besides the well-known function of thyroid hormones (THs) for regulating metabolism, it has recently been discovered that THs are also involved in testicular development in mammalian and non-mammalian species.
