Differences in the expression of opioid peptides in Dahl salt-resistant and salt-sensitive rats
… hypertension. Because of the evidence that opioid peptides and their receptors can be involved in cardiovascular regulation, the objective of this study was to test the hypothesis that /3-endorphin and enkephalins are involved in the development of hypertension through the determination of …

Hormonal aspects of reproductive suppression in the naked mole-rat, Heterocephalus glaber
… suppression in this species: endogenous opioid peptides and cortisol.

Opioid regulation of ingestive behavior in the domestic fowl
… were conducted to examine the role of endogenous opioid peptides in the regulation of ingestive behavior in the domestic fowl. In the first study, the dose-response relationships of two opioid antagonists, naloxone and naltrexone, were evaluated in Rock-Comish (RC) and Single-Comb White Leghorn …

The Role of Mu Opioid Receptors in the Behavioral Effects of Cocaine
… systems including the endogenous opioid system. The effects of selectively antagonizing mu opioid receptors on cocaine-induced behaviors were evaluated during this research. This research also evaluated the effect of selectively antagonizing dopamine D1 or D2 receptors on …

Hormonal and metabolic responses to opioid antagonism during dynamic exercise : influence of exercise intensity
… to investigate the role of the endogenous opioid peptides in substrate utilization and hormonal responses to exercise, eight trained cyclists completed two exercise trials at each of two distinct intensity/duration combinations. Briefly, cyclists completed two trials at 70% VO2max for 90 …

Maternal separation in the rat : long-term effects of early life events on emotionality, drug response and neurobiology
… adult Wistar rat offspring. Furthermore, brain opioid peptides, monoamines, corticosterone levels and weight of adrenal and thymus glands were measured. When separating pups as intact litters kept in incubators, there were mainly no alterations in emotionality, amphetamine-induced locomotor …

Effect of naloxone on serum luteinizing hormone concentrations during the early postpartum period and the estrous cycle in primiparous and multiparous holstein cows
… to investigate the effect of naloxone, an opioid receptor antagonist, on pituitary LH secretion in Holstein cows during two periods after parturition and two phases of the estrous cycle. In experiment 1, 24 cows (12 primiparous; 12 multiparous) received either saline (n = 12) or 1 mg/kg …

Opioid inhibition of the growth of the transplantable androgen-responsive (AR) Shionogi mouse mammary carcinoma (SC115)
… carcinoma (SC115). In addition, the effects of opioid agonists and antagonists on the growth of SC115tumor cells in primary culture were examined. The possible role of opioids in mediating the differential tumor growth rates of mice exposed to experimental housing groups was also examined.SC115 …

Transcriptional regulation of human mu-opioid receptor gene: functional characterization of activating and inhibitory transcription factors
… therefore, transcription factors modulating mu-opioid receptor (MOPr) expression in neurons and immune cells are here investigated. More precisely, I focused my attention on IGF-I modulation of MOPr in neurons and T-cell receptor induction of MOPr expression in T-lymphocytes. Three different …

ACID-SENSING ION CHANNELS: TARGETS FOR NEUROPEPTIDE MODULATION AND NEURONAL DAMAGE
Acid-sensing ion channels (ASICs) are proton-gated channels expressed in neurons in the central and peripheral nervous systems. These ion channels are sensors for extracellular pH and contribute to a variety of normal functions including learning and memory, seizure termination, fear, anxiety, and …
