Salivary beta-endorphin in nonsuicidal self-injury: an ambulatory assessment study. [PDF]

open access: yesNeuropsychopharmacology, 2021
Nonsuicidal self-injury (NSSI) is a prevalent and impairing behavior, affecting individuals with and without additional psychopathology. To shed further light on biological processes that precede and result from NSSI acts, we built on previous cross ...

The effects of beta-endorphin: state change modification. [PDF]

open access: yesFluids Barriers CNS, 2015
Beta-endorphin (β-END) is an opioid neuropeptide which has an important role in the development of hypotheses concerning the non-synaptic or paracrine communication of brain messages.

beta-endorphin-(1-27) is an antagonist of beta-endorphin analgesia. [PDF]

open access: yesProceedings 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 ...

The role of endogenous beta-endorphin and enkephalins in ethanol reward. [PDF]

open access: yesNeuropharmacology, 2013
Substantial evidence has implicated the endogenous opioid system in alcohol reinforcement. However, the role of each opioid peptide in alcohol reinforcement and, particularly, reward is not fully characterized.

Beta-Endorphin and Male Infertility [PDF]

open access: yesArchives 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 ...

Opioid Receptors in Immune and Glial Cells-Implications for Pain Control [PDF]

open access: yes, 2020
Opioid receptors comprise μ (MOP), δ (DOP), κ (KOP), and nociceptin/orphanin FQ (NOP) receptors. Opioids are agonists of MOP, DOP, and KOP receptors, whereas nociceptin/orphanin FQ (N/OFQ) is an agonist of NOP receptors.

beta-Endorphin-induced analgesia is inhibited by synthetic analogs of beta-endorphin. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1984
Competitive antagonism of human beta-endorphin (beta h-EP)-induced analgesia by synthetic beta h-EP analogs with high in vitro opiate receptor binding to in vivo analgesic potency ratio has been demonstrated. A parallel shift of the dose-response curve for analgesia to the right was observed when either beta h-EP or [ Trp27 ] -beta h-EP was coinjected ...

Heroin-piracetam mixture: suggested mechanisms of action and risks of misinterpretation for drug users [PDF]

open access: yes, 2017
Piracetam is a positive allosteric modulator of the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor that has been frequently used in the treatment of cognitive disorders.

The emotional and hormonal pathways of labour and birth: integrating mind, body and behaviour [PDF]

open access: yes, 2013
Background: Women have described normal labour and birth in terms of their emotions. Major advances in knowledge have occurred within the sciences resulting in an understanding of emotions as prime directors of human behaviour which is orchestrated by ...

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]

open access: yesThe 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 ...
