Dissociation of enhanced ornithine decarboxylase activity and optic nerve regeneration in goldfish
(Elsevier, 1982-06)
The significance of a previously observed increase in retinal ornithine decarboxylase (ODC, EC 4.1.1.17) following optic nerve crush was investigated in goldfish using a specific irreversible inhibitor of ODC, [alpha]-di ...
Muscarinic cholinergic receptors in human infant forebrain: [3H]Quinuclidinyl benzilate binding in homogenates and quantitative autoradiography in sections
(Elsevier, 1985-04)
The ontogeny of muscarinic receptors in human brain was studied by comparing [3H]quinuclidinyl benzilate ([3H]QNB) binding in postmortem tissue from infants 1 week to 3 months of age with binding in adult specimens. ...
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 ...
Motivated behavior and the estrous cycle in rats
(Elsevier, 1981)
(1) The estrous cycle in the rat may be used to study recurrent changes in motor behaviors and motivation which are strongly related to cyclic hormonal and CNS changes. (2) The peak in motivated behaviors occurs during a ...
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 ...
Neurotransmitter chemistry of lissencephalic cortex induced in ferrets by fetal treatment with methylazoxymethanol acetate
(Elsevier, 1982-07)
Treatment of pregnant ferrets with 15 mg/kg of methylazoxymethanol acetate (MAM) at 33 days of fetal gestation results in offspring with cortical hypoplasia and lissencephally. Neurochemical analysis of 5 areas of cortex ...
Dendritic growth of dapi-accumulating amacrine cells in the retina of the goldfish
(Elsevier, 1989-11-01)
The dendritic growth of amacrine cells was studied in the retina of the goldfish. Those cells that accumulated the intraocularly injected fluorescent dye 4,6-diamidino-2-phenylindole (DAPI) were compared in retinal wholemounts ...
