PMID: 26175759
J Family Reprod Health. 2015 Jun;9(2):51-7.

OBJECTIVE: To determine the effects of Ramadan fasting on serum levels of stress neurohormones in Iranian women with polycystic ovary syndrome (PCOS).MATERIALS AND METHODS: This study was a clinical trial and was performed during July 2011 (month of Ramadan)...

ASSESSMENT OF BETA-ENDORPHIN AND MELATONIN CIRCADIAN RHYTHMS IN NORMOTENSIVE OBESE WOMEN OF REPRODUCTIVE AGE.

Ostrowska Z, Buntner B, Zwirska-Korczala K, Pardela M, Marek B.
PMID: 10467433
Endocr Regul. 1997 Dec;31(4):193-200.

We have evaluated the relationship between beta-endorphin (beta-EP) and melatonin (MEL) secretion as determined at 3 h intervals over a 24 h period in 27 normotensive obese women of different phenotypes (12 showing gynoid-type and 15 showing android-type of...

Concentration of neuropeptide Y, galanin, &bgr;-endorphin, vasoactive intestinal peptide and gonadotropin releasing hormone in the hypothalamus of gilts during the estrous cycle.

Neuro endocrinology letters

Ziecik AJ, Okrasa S, Kalamarz H, Lakomy M, Kraeling RR.
PMID: 11458205
Neuro Endocrinol Lett. 1999;20(6):397-403.

Numerous reports indicate that peptides isolated from the brain such as beta-endorphin (beta-END), neuropeptide Y (NPY), galanin (GAL) or vasoactive intestinal peptide (VIP), modulate secretion of gonadotropins and prolactin. The objective of the present experiment was to determine concentrations...

Endogenous opioid analgesia in peripheral tissues and the clinical implications for pain control.

Therapeutics and clinical risk management

Kapitzke D, Vetter I, Cabot PJ.
PMID: 18360571
Ther Clin Risk Manag. 2005 Dec;1(4):279-97.

Opioid receptors are widely expressed in the central and peripheral nervous system as well as in numerous nonneuronal tissues. Both animal models and human clinical data support the involvement of peripheral opioid receptors in analgesia, particularly in inflammation where...

Sensibility threshold in depressive and nondepressive patients with chronic orofacial pain.

Anesthesia progress

Hampf G, Aalberg V, Ekholm A, Vikkula J.
PMID: 19598700
Anesth Prog. 1988 Jul;35(4):152-4.

Sensibility threshold was measured in patients with depressive and nondepressive psychiatric disorders, where both groups were suffering from chronic orofacial pain. The control patients had no pain and no signs of mental disturbance. Patients with major depressive disorders had...

Stereochemical basis for a unified structure activity theory of aromatic and heterocyclic rings in selected opioids and opioid peptides.

Perspectives in medicinal chemistry

Goldberg JS.
PMID: 20212915
Perspect Medicin Chem. 2010 Feb 18;4:1-10. doi: 10.4137/pmc.s3898.

This paper presents a novel unified theory of the structure activity relationship of opioids and opioid peptides. It is hypothesized that a virtual or known heterocyclic ring exists in all opioids which have activity in humans, and this ring...

Desensitization of superfused isolated ovine anterior pituitary cells to human corticotropin-releasing factor.

Journal of neuroendocrinology

Thomson M, Chan EC, Falconer J, Madsen G, Geraghty S, Curryert N, Boulton J, Smith R.
PMID: 19210381
J Neuroendocrinol. 1990 Apr 01;2(2):181-7. doi: 10.1111/j.1365-2826.1990.tb00848.x.

Abstract We have employed an in vitro system to study the time-course of beta-endorphin (beta-EP) immunoreactivity release from anterior pituitary cells stimulated with corticotropin-releasing factor (CRF) and whether exposure to CRF desensitizes the cells to subsequent stimulation. Ovine anterior...

Synchronous Pulsatile Release of Luteinizing Hormone and Immunoreactive Beta-Endorphin from the Human Pituitary in vitro.

Journal of neuroendocrinology

Rossmanith WG, Yen SS, Rasmussen DD.
PMID: 19210403
J Neuroendocrinol. 1990 Feb 01;2(1):91-4. doi: 10.1111/j.1365-2826.1990.tb00398.x.

Abstract An in vitro perifusion system employing very frequent (30 s) perifusate collectionswas utilized to investigate the relationship between pulsatile release of luteinizing hormone (LH) and immunoreactive beta-endorphin (ibeta-END) during individual perifusions of adult human anterior hemipituitaries. Each of...

Arcuate Nucleus and Preoptic Area Involvement in Beta-Endorphin-lnduced Release of Prolactin in Conscious Ovariectomized Ratsdagger.

Journal of neuroendocrinology

Voogt JL, Reseh G, Turkington S.
PMID: 19210416
J Neuroendocrinol. 1989 Dec 01;1(6):449-53. doi: 10.1111/j.1365-2826.1989.tb00146.x.

Abstract The ability of ss-endorphin (ss-END) to release prolactin and the ability of naloxone to block prolactin's release when delivered to specific hypothalamic areas via push-pull perfusion was studied in unrestrained, conscious, Ovariectomized rats. Perfusion of either the arcuate...

Pubertal changes in pro-opiomelanocortin and gonadotropin-releasing hormone gene expression in the brain of the male monkey.

Molecular and cellular neurosciences

Vician L, Adams LA, Clifton DK, Steiner RA.
PMID: 19912781
Mol Cell Neurosci. 1991 Feb;2(1):31-8. doi: 10.1016/1044-7431(91)90037-o.

Puberty in the primate is initiated by an amplification of the pulsatile secretion of gonadotropin-releasing hormone (GnRH); however, the factors responsible for this a pubertal activation of GnRH neurons are unknown. We examined whether the biosynthetic capacity of GnRH...

Epidermal growth factor enhances ACTH secretion and expression of POMC mRNA by corticotropes in mixed and enriched cultures.

Molecular and cellular neurosciences

Childs GV, Patterson J, Unabia G, Rougeau D, Wu P.
PMID: 19912804
Mol Cell Neurosci. 1991 Jun;2(3):235-43. doi: 10.1016/1044-7431(91)90050-x.

Previous studies have shown that epidermal growth factor (EGF) stimulates the release of adrenocorticotropin (ACTH) in vivo and in vitro by amplifying the effects of corticotropen-releasing hormone (CRH). The aim of the present studies was to compare responses to...

The Secretory Granule Protein 7B2 is Secreted in Parallel with Proopiomelanocortin and its End-Products by the Mouse Corticotroph Tumour Cells AtT-20.

Journal of neuroendocrinology

Vieau D, Tougard C, Rosenbaum E, Lenne F, Bertagna X.
PMID: 19215457

First isolated in porcine pituitary glands the protein 7B2 subsequently proved to be a specific biochemical marker of the secretory granules. Likewise 7B2 was detected in almost all normal and tumoral endocrine tissues. Unexpectedly, several authors failed to demonstrate...
