Characterization of [beta]-endorphin-related peptides in the caudal medulla oblongata and hypothalamus of the prenatal, postnatal and adult rat
(Elsevier, 1991-09-19)
A comparison was made of [beta]-endorphin (B-END) concentrations versus post-translation products during the perinatal period in the hypothalamus and the caudal medulla oblongata. The concentration of B-END-like immunoreactivity ...
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 ...
Cyclic AMP accumulation alters calmodulin localization in SK-N-SH human neuroblastoma cells
(Elsevier, 1992-01)
In SK-N-SH human neuroblastoma cells, the muscarinic agonist carbachol promotes polyphosphoinositide (PPI) hydrolysis via M3 receptors and increases cyclic AMP levels through an unidentified mechanism. Activation of PPI ...
Diurnal Regulation of Glucocorticoid Receptor and Mineralocorticoid Receptor mRNAs in Rat Hippocampus
(Elsevier, 1993-04)
The present studies were undertaken to determine whether hippocampal glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) biosynthesis, as inferred from mRNA expression, exhibit diurnal patterns of activation ...
Phosphorylation of neuromodulin in rat striatum after acute and repeated, intermittent amphetamine
(Elsevier, 1993-12)
Repeated, intermittent treatment of rats with amphetamine results in a sensitization of locomotor and stereotyped behaviors that is accompanied by an enhancement in stimulus-induced dopamine release. Increased phosphorylation ...
Lipid-Dependent Modulation of Ca 2+ Availability in Isolated Mossy Fiber Nerve Endings
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1997-10)
An enhancement of glutamate release from hippocampal neurons has been implicated in long-term potentiation, which is thought to be a cellular correlate of learning and memory. This phenomenom appears to be involved the ...
Effects of single and repeated electroconvulsive therapy sessions on plasma ACTH, prolactin, growth hormone and cortisol concentrations
(Elsevier, 1991)
To study the effects of electroconvulsive therapy (ECT) on hormone release, we measured circulating concentrations of adrenocorticotropic hormone (ACTH), prolactin (PRL), growth hormone (GH) and cortisol (CORT) immediately ...
Isolation and Immunocytochemical Characterization of Three Tachykinin-Related Peptides from the Mosquito, Culex salinarius
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1998-02)
Three myotropic peptides belonging to the Arg-amide insect tachykinin family were isolated from whole-body extracts of the mosquito, Culex salinarius . The peptides, APSGFMGMR-NH 2 , APYGFTGMR-NH 2 and APSGFFGMR-NH 2 ...
Discordant changes in plasma ACTH and [beta]-lipotropin/[beta]-endorphin levels in Clshing's disease patients with depression
(Elsevier, 1992-11)
Cushing's Disease is often associated with a depressive syndrome, with mood, vegetative, and cognitive abnormalities of variable severity. In 11 patients with (pituitary ACTH-dependent) Cushing's disease (10 women, 1 man), ...
