Endorphins: "opiates for the masses".
Endogenous opioid peptides rose to prominence with the discovery of the enkephalins in 1975. Since then, a vast amount of research has been directed toward understanding their role in normal and pathophysiological situations.

Non-opiate [beta]-endorphin fragments and dopamine--IV [gamma]-type endorphins may control dopaminergic systems in the nucleus accumbens [PDF]
Chronic treatment with des-enkephalin-γ-endorphin (DEγE, β-endorphin 6–17) twice daily for 10 days into the nucleus accumbens of rats resulted in hypoactivity, while similar treatment with γ-endorphin antiserum led to a marked hyperactivity.

Roger Guillemin discovered and characterized the hypothalamic factors that control anterior pituitary functions. He consequently demonstrated that these brain peptides regulate a large number of major body activities through neuroendocrine mechanisms ...

Endorphins: what are they? How are they measured? What is their role in exercise?
A generalized knowledge of opiates has been available for centuries, but it was not until 1975, following the isolation of the first endogenous opioids, that it was appreciated that their analgesic properties were mediated via specific receptors.

Biotransformation of endorphins by a synaptosomal plasma membrane preparation of rat brain and by human serum [PDF]
β-Endorphin (β-LPH 61–91), γ-endorphin (61–77), des-tyrosine-γ-endorphin (62–77), α-endorphin (61–76), and β-LPH 61–69 either labeled with [125I] at the N-terminal 61-tyrosine residue or unlabeled were incubated with a crude synaptosomal plasma membrane ...

Slaughter of cattle without stunning: Questions related to pain, stress and endorphins
International audienceEEG studies have suggested that cattle perceive pain when bled without stunning. The present study on bleeding without stunning, compared cows that had received a local anaesthetic on the site of the bleeding cut (Lurocaine; Luro ...

Background: Previous studies have often focused on plasma beta-endorphin (ß-EP) and cortisol responses to either sub-maximal or maximal exercise. However, little research has been conducted on the effects of professional exercise sessions on ß-EP and ...
