Beta-Endorphin and Male Infertility [PDF]
Archives of Andrology, 1986 Beta-endorphin (beta-ED) levels were evaluated in blood and seminal plasma of men with infertility due to varicocele, obstructive and nonobstructive azoospermia, and idiopathic oligoasthenospermia. The relation of this opiate to serum levels of gonadotropins, prolactin, testosterone, androstenedione, and dehydroepiandrosterone sulfate has also been ...

beta-endorphin-(1-27) is an antagonist of beta-endorphin analgesia. [PDF]
Proceedings of the National Academy of Sciences, 1984 beta h-Endorphin-(1-27), a naturally occurring fragment of human beta-endorphin (beta h-endorphin), diminishes the analgesic effect of beta h-endorphin when coinjected intra-cerebroventricularly into mice. A parallel shift in the dose-response curve of beta h-endorphin in the presence of beta h-endorphin-(1-27) suggests competition at the same site ...

Pain reactivity and plasma beta-endorphin in children and adolescents with autistic disorder. [PDF]
PLoS ONE, 2009 BACKGROUND:Reports of reduced pain sensitivity in autism have prompted opioid theories of autism and have practical care ramifications. Our objective was to examine behavioral and physiological pain responses, plasma beta-endorphin levels and their ...

Pain sensitivity and observer perception of pain in individuals with autistic spectrum disorder [PDF]
, 2013 The peer-reviewed literature investigating the relationship between pain expression and perception of pain in individuals with ASD is sparse. The aim of the present systematic PRIMSA review was twofold: first, to see what evidence there is for the widely

Biosynthesis and release of beta-endorphin-, N-acetyl beta-endorphin-, beta-endorphin-(1-27)-, and N-acetyl beta-endorphin-(1-27)-like peptides by rat pituitary neurointermediate lobe: beta-endorphin is not further processed by anterior lobe [PDF]
The Journal of Neuroscience, 1981 Continuous labeling and pulse-chase techniques were employed to study the synthesis and secretion of multiple forms of immunoreactive beta- endorphin by cultured dispersed rat anterior lobe cells and intact neurointermediate pituitary lobe. Cell and medium extract immunoreactive beta-endorphin (specific immunoprecipitation and radioimmunoassay ...

Pro-opiomelanocortin co-localizes with corticotropin-releasing factor in axon terminals of the noradrenergic nucleus locus coeruleus [PDF]
, 2006 We previously demonstrated that the opioid peptide, enkephalin, and corticotropin-releasing factor (CRF) are occasionally co-localized in individual axon terminals but more frequently converge on common dendrites in the locus coeruleus (LC).
