... the hypothalamus, thus implicating neuroendocrine programming in a PA nonhuman primate model for PCOS at a hypothalamic neuronal (LH pulse frequency) location as well as at a pituitary gonadotrope (LH pulse amplitude) location. Quantitative assessment of episodic LH release in the systemic circulation was used...

... of these effects. Little is known about these neuropeptide interactions in the primate. We have therefore examined the effects of IL-1α on the release of CRH in the ovariectomized rhesus monkey in vitro and in vivo. In 3 animals, the effect of IL-1α on CRH release from the superfused hypothalamus was studied...

..., it is unlikely that SP neurons could transduce the action of P on prolactin secretion in primates, but BE neurons may play an intermediary role. 20 06 1995 12 09 1995 9 4 2008 © 1996 S. Karger AG, Basel 1996 Copyright / Drug Dosage / Disclaimer Copyright: All rights reserved. No part...

...Ennian Xiao; Linna Xia-Zhang; David Thornell; Edward Shalts; Michel Ferin In the primate, arginine vasopressin (AVP) is known to activate the hypothalamo-pituitary-adrenal axis and to inhibit LH secretion. In the present study, we investigate the role of the endogenous opioid peptides...

...Sheila M. Brooke; Anna M. de Haas-Johnson; Jay R. Kaplari; Stephen B. Manuck; Robert M. Sapolsky We have studied some of the neuroendocrine and social correlates of dexamethasone resistance in a nonhuman primate population. Subjects were 51 male Macaca fascicularis monkeys with known behavioral...

... primate, we performed an immuno-histochemical analysis of the cellular localization of AMPA-type glutamate receptor subunits in the pineal gland of the macaque. Staining obtained with an antibody specific to GluRl receptor sub unit showed that this subunit is present in interstitial cells and astrocyte...

Melatonin did not affect basal or thyroid stimulating hormone releasing hormone (TRH)-stimulated values of thyroid stimulating hormone (TSH) or prolactin. No effects were...

... [ 29 ]. Moreover, the gene for TH is expressed in the monkey testis and similar cells were found in the ovary of the monkey [ 30, 31 ], lending further support for the existence of these cells at least in primates. This cell type may act alone and/or in concert with the extrinsic sympathetic...

... mechanisms underlying the initiation of puberty in primates is discussed. Four-centimeter-long, estradiol-containing or blank Silastic capsules were made from Silastic medical grade tubing (internal diameter 0.132 inch; outside diameter 0.183 inch).

...Joaquin Lado-Abeal; Reid L. Norman During puberty, primates begin to secrete LH, and presumably GnRH, at night and then eventually throughout the day as they mature. We examined the role of vasopressin, a putative inhibitor of the GnRH pulse generator, on LH secretion in pubertal male macaques both...
