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) ...
Immunocytochemistry of the C-terminal peptide of propressophysin (CPP): Relationship to vasopressin, oxytocin and neurophysin
(Elsevier, 1983-07)
Arginine-vasopressin (AVP) and its associated neurophysin (AVP-NP) are synthesized via a precursor, propressophysin, which also contains a 39 amino acid glycopeptide at its C-terminus (C-terminus of propressophysin, or ...
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 ...
The Role of the Hippocampal Mineralocorticoid and Glucocorticoid Receptors in the Hypothalamo-Pituitary-Adrenal Axis of the Aged Fisher Rat
(Elsevier, 1994-10)
The aging process has been frequently associated with hippocampal neuredegeneration, loss of corticosteroid receptors, and, at the same time, dysfunction of the hypothalamo-pituitary-adrenal (HPA) axis. We were interested ...
Dynorphin immunocytochemistry in the rat central nervous system
(Elsevier, 1982)
The distribution of dynorphin in the central nervous system was investigated in rats pretreated with relatively high doses (300-400 [mu]g) of colchicine administered intracerebroventricularly. To circumvent the problems ...
Expression of behavioral sensitization to ethanol by DBA/2J mice: the role of NMDA and non-NMDA glutamate receptors
(Springer-Verlag, 2003-05)
Rationale. Behavioral sensitization has been accorded a central role in contemporary theories of drug addiction. Accordingly, a substantial effort has been made to determine the processes mediating sensitization to ...
Sweet taste preference in women smokers: Comparison with nonsmokers and effects of menstrual phase and nicotine abstinence
(Elsevier, 1991-12)
Cigarette smokers weigh less than comparably aged nonsmokers, and many gain weight following cessation. Though some evidence suggests that nicotine reduces food intake, with a selective effect on sweet-tasting foods, the ...
Immunohistochemical localization of aminopeptidase M in rat brain and periphery: Relationship of enzyme localization and enkephalin metabolism
(Elsevier, 1987)
An antiserum specific for rat aminopeptidase M has been used for the immunohistochemical localization of the enzyme in rat brain and peripheral tissues. The enzyme in brain is localized exclusively on blood vessels. Within ...
