Beta-endorphin in pregnancy

European Journal of Obstetrics & Gynecology and Reproductive Biology, 1984
Concentrations of maternal plasma beta-endorphin (beta-EP) as measured by radioimmunoassay decline during pregnancy, reaching a nadir during the second trimester, rise during labor, remain elevated during the early postpartum period and are increased prior to elective cesarean section in the absence of labor.

Beta-endorphin-(1–27) antagonizes beta-endorphin-induced hypothermia in mice

Peptides, 1987
The effects of beta-endorphin and beta-endorphin-(1-27) on the body temperature of mice was studied at an ambient temperature of 10 degrees C. Intracerebroventricular injection of beta-endorphin (0.25-4 micrograms) and beta-endorphin-(1-27) (0.61 to 10 micrograms) caused a dose-related hypothermia. The duration of hypothermia induced by beta-endorphin-(

Beta-endorphins in essential blepharospasm

Neuro-Ophthalmology, 1994
The effect of the administration of adrenergic and serotoninergic substances on beta-endorphins was evaluated in four patients with essential blepharospasm. The lack of beta-endorphin release following administration of adrenergic agents demonstrated that this aminergic action on the hypothalamus-pituitary adrenal axis is modified in the presence of ...

Beta Endorphin Concentrations in Human Milk

Journal of Pediatric Gastroenterology and Nutrition, 2001
ABSTRACTBackgroundThe source and regulatory mechanisms that elevate beta‐endorphin (β‐EP) approximately twofold higher than circulating plasma levels in the colostrum of lactating mothers are still unknown, and no studies have examined β‐EP availability previously during maturation phases of human milk. Therefore, the aim of this study was to determine

The complete sequence of sheep beta-endorphin

Biochemical and Biophysical Research Communications, 1977
Abstract Automatic sequencing of an isothiocyano naphthalene sulfonic acid derivative of sheep beta-endorphin, allowed the positioning of 24 out of 31 residues. Peptide mapping of a tryptic digest of the native molecule permitted the filling of remaining gaps.
