Multiple steroid hormone levels in depressed patients and normal controls before and after exogenous ACTH
(Elsevier, 1991)
Forty depressed patients and 36 age- and sex-matched controls were given 250 [mu]g ACTH1-24 by bolus. Plasma steroid hormone levels were measured prior to and 60 min after ACTH administration. The depressed patients had ...
Continued search for the cellular signals that regulate regeneration of dopaminergic neurons in goldfish retina
(Elsevier, 1993-12-17)
Intraocular injections of low doses (0.7-1.4 mM estimated intraocular concentration) of 6-hydroxydopamine (6OHDA) selectively destroy dopaminergic neurons in the inner nuclear layer (INL) of goldfish retina, and they never ...
Electrophysiological actions of VIP in rat somatosensory cortex
(Elsevier, 1991)
Electrophysiological and biochemical studies suggest that VIP may exert a facilitating action in the neocortical local circuitry. In the present study, we examined the actions of VIP and VIP + norepinephrine (NE) on ...
c-Myc Does Not Require Max for Transcriptional Activity in PC-12 Cells
(Elsevier, 1994-06)
The c-Myc proto-oncogene is a basic helix-loop-helix leucine zipper (b/HLH/LZ) protein that participates in cellular growth and differentiation. The expression of cMyc mRNA is rapidly induced by nerve growth factor (NGF) ...
In Vitro release of hypothalamic [beta]-endorphin [beta]E by arginine vasopressin, corticotropin-releasing hormone and 5-hydroxytryptamine: Evidence for release of opioid active and inactive [beta]E forms
(Elsevier, 1990-05)
The aims of the present experiments were: 1) to test whether substances which modulate beta-endorphin-immunoreactive [beta]E-ir release from the pituitary gland might act similarly in hypothalamic tissue; and 2) to further ...
[kappa]1 Receptor mRNA Distribution in the Rat CNS: Comparison to [kappa] Receptor Binding and Prodynorphin mRNA
(Elsevier, 1994-04)
Three opioid receptor types have been identified in the CNS and periphery that are referred to as [mu], [delta], and [kappa]. The present study examines the mRNA distribution of the [kappa]1 receptor in the rat brain and ...
Glutamate uptake system in the presynaptic vesicle: Glutamic acid analogs as inhibitors and alternate substrates
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1993-01)
A variety of naturally occurring amino acids, their isomers, and synthetic analogs were tested for their ability to inhibit uptake of [ 3 H]glutamate into presynaptic vesicles from bovine cerebral cortex. Strongest inhibition ...
Autoradiographic quantification of muscarinic cholinergic synaptic markers in bat, shrew, and rat brain
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1994-05)
We employed radioligand binding autoradiography to determine the distributions of pre- and postsynaptic cholinergic radioligand binding sites in the brains of two species of bat, one species of shrew, and the rat. High ...
Molecular and electrophysiological characterization of a allelic variant of the rat [alpha]6 GABAA receptor subunit
(Elsevier, 1992-11)
A 1.45 kb DNA sequence encoding the rat [alpha]6 GABAA receptor subunit (nucleotides 33-1483) was clonedfrom a Sprague-Dawley rat brain cDNA library by PCR amplification. Dideoxy sequencing of two individual clones revealed ...
Tyrosine hydroxylase mRNA-containing neurons in the medial amygdaloid nucleus and the reticular nucleus of the thalamus in the Syrian hamster
(Elsevier, 1993-11)
To confirm previous immunocytochemical findings in colchicine-treated Syrian hamsters, in situ hybridization was used to investigate the distribution of TH mRNA-containing cells in the medial amygdaloid nucleus (Me) and ...
