Interactions between testicular serotoninergic, catecholaminergic, and corticotropin-releasing hormone systems modulating cAMP and testosterone production in the golden hamster
(Karger, 2002-07)
We previously reported the presence of serotonin (5-HT) in testes from golden hamster, a photoperiodic species which is a useful model for the study of states of male (in)fertility. The aims of this study were to investigate: ...
Psiconeuroendocrinologia do transtorno de estresse pós-traumático
(Associação Brasileira de Psiquiatria - ABP, 2007-05-01)
OBJECTIVE: To review the literature on neurobiological findings related to hypothalamic-pituitary-adrenal axis dysfunctions associated with posttraumatic stress disorder. METHOD: The relevant scientific findings were ...
Cannabinoid CB1 receptor restrains accentuated activity of hypothalamic corticotropin-releasing factor and brainstem tyrosine hydroxylase neurons in endotoxemia-induced hypophagia in rats
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
It is well known that endocannabinoids play an important role in the regulation of food intake and body weight. Endocannabinoids and cannabinoid receptors are found in the hypothalamus and brainstem, which are central areas ...
Ghrelin activates hypophysiotropic corticotropin-releasing factor neurons independently of the arcuate nucleus
(Pergamon-Elsevier Science Ltd, 2016-05)
Previous work has established that the hormone ghrelin engages the hypothalamic-pituitary-adrenal neuroendocrine axis via activation of corticotropin-releasing factor (CRF) neurons of the hypothalamic paraventricular nucleus ...
Direct effect of melatonin on Syrian Hamster testes: Mel1a receptors, inhibition on androgen production, and interaction with the local corticotropin-releasing hormone (CRH) system
(Endocrine Society, 2005-03-01)
Besides the hypothalamus and pituitary, melatonin action at the testicular level has been recently suggested. Therefore, we investigated in the Syrian hamster, a well-characterized seasonal breeder, melatonin action on ...
GABAergic mediation of stress-induced secretion of corticosterone and oxytocin, but not prolactin, by the hypothalamic paraventricular nucleus
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The hypothalamus-pituitary-adrenal axis (HPA) participates in mediating the response to stressful stimuli. Within the HPA, neurons in the medial parvocellular region of paraventricular nucleus (PVN) of the hypothalamus ...
