Cloning and characterization of a pharmacologically distinct A1 adenosine receptor from guinea pig brain
(Elsevier, 1994-10)
Three full-length cDNA clones encoding the guinea pig A1 adenosine receptor have been isolated by polymerase chain reaction (PCR) and low-stringency hybridization screening of a guinea pig brain cDNA library. These three ...
Social defeat alters the acquisition of cocaine self-administration in rats: role of individual differences in cocaine-taking behavior
(Springer-Verlag, 2001-12)
Rationale : It is known that social defeat can modulate cocaine self-administration. However, it is unclear whether this psychosocial stressor affects drug-taking behavior to the same extent across all individual animals, ...
Plasma measures of B-endorphin-like immunoreactivity in depressives and other psychiatric subjects
(Elsevier, 2006-04-07)
We report the utilization of a very sensitive radioimmunoassay for plasma B-END, which has enabled us to examine the suppressibility of B-END-like material, under dexamethasone challenge, on a population of depressed ...
The signal peptide of pro-opiomelancortin: Validation of a specific radioimmunoassay
(Elsevier, 2006-04-07)
The N-terminus portion of the POMC leader sequence (signal peptide) was synthesized, and an antiserum was raised against it. A radioimmunoassay was developed which is effective at a dilution of 1:500,000, and sensitive at ...
Chronic electroconvulsive shock treatment elicits up-regulation of CRF and AVP mRNA in select populations of neuroendocrine neurons
(Elsevier, 1989-11-06)
The effects of repeated electroconvulsive seizures (ECS) on expression of mRNAs coding for corticotropin-releasing factor (CRF) and arginine vasopressin (AVP) in neuroendocrine neurons of the hypothalamo-pituitary-adrenocortical ...
The degradation of dynorphin A in brain tissue in vivo and in vitro
(Elsevier, 1987)
The demonstration of analgesia following in vivo administration of dynorphin A (Dyn A) has been difficult. In contrast, a number of electrophysiological and behavioral effects reported with in vivo injection of Dyn A can ...
Further characterization of the extra-arcuate alpha-melanocyte stimulating hormone-like material in hypothalamus: Biochemical and anatomical studies
(Elsevier, 1986-04)
Previous studies had shown the existence of an extra-arcuate cell group in lateral hypothalamus which contains alpha-melanocyte stimulating hormone (a-MSH)-like immunoreactivity, but no other pro-opiomelanocortin (POMC) ...
Acute systemic administration of morphine selectively increases mu opioid receptor binding in the rat brain
(Elsevier, 1984-12)
Opioid receptor binding, including the mu, delta, and kappa receptor subtypes, was compared in morphine-injected and control rats. Brain tissues were homogenized and centrifuged either one or two times prior to receptor ...
Effects of contextual or olfactory cues previously paired with morphine withdrawal on behavior and pain sensitivity in the rat
(Springer-Verlag, 2001-08)
Rationale: Pavlovian conditioning processes have been accorded an important role in maintaining persistent opiate administration. At least one locus for this contribution is during opiate withdrawal. These experiments ...
