Identification and characterization of the adenosine 3',5'-cyclic monophosphate binding proteins appearing during the development of Dictyostelium discoideum
(Elsevier, 1980-05-07)
A photosensitive, radioactive analogue of cyclic adenosine monophosphate, 8-azido-adenosine 3',5'-[32P]monophosphate (8-N3-cyclic AMP), was used to label the cyclic AMP binding proteins of Dictyostelium discoideum. During ...
Quantitation of oligosaccharides released by the [beta]-elimination reaction
(Elsevier, 1980-01-01)
A quantitative micromethod has been described for monitoring the rate and extent of the [beta]-elimination reaction as applied to O-glycosyl-glycoproteins utilizing alkaline tritiated borohydride. The procedure simultaneously ...
Behavioral effects of dynorphin1-13 in the mouse and rat: Initial observations
(Elsevier, 1980)
Dynorphin is a recently identified, pharmacologically potent endogenous opioid peptide. Heretofore it has not been characterized for its behavioral effects. The effects of centrally infused dynorphin upon a variety of ...
Direct determination of selected metals in refractory powder micro samples with exploding thin film excitation
(Elsevier, 1980)
The direct determination of metallic elements in powder micro samples is explored. Emphasis is placed on refractory materials prepared as alcoholic suspensions of their powders. Silver thin films are vacuum deposited on ...
Percolation analog for a two-component liquid-vapor system
(Elsevier, 1980-10-15)
Generalized site-bond percolation theory is utilized to provide an analog for a two-component liquid-vapor system in the phase transition region. The percolation model exhibits a behaviour typical of a non-ideal real ...
Sensitive gas chromatographic assay for the quantitation of bretylium in plasma, urine and myocardial tissue
(Elsevier, 1980-01-11)
A sensitive analytical method has been developed for the quantitation of bretylium in plasma, urine and myocardial tissue. Bretylium and the internal standard, UM-360 (o-iodobenzyltrimethylammonium), are extracted and ...
The effect of dietary supplementation of fish oil on experimental myocardial infarction
(Elsevier, 1980-12)
The effect of altering the abundance of precursors and inhibitors of prostaglandin formation by dietary supplements of fish oil was investigated in dogs with experimentally induced myocardial infarction. Prior to induction, ...
Interaction of opiate peptide and noradrenalin systems: Light microscopic studies
(Elsevier, 1980)
In this light microscopic immunocyto-chemical study [beta]-Endorphin ([beta]-END), leu-enkephalin and dopamine-[beta]hydroxylase (DBH) antisera are used to obtain an overview of the interaction of the noradrenergic and ...
Hydroxylation and expoxidation reactions catalyzed by synthetic metalloporphyrinates. Models related to the active oxygen species of cytochrome P-450
(Elsevier, 1980-02)
Iodosylbenzene has been found to react with catalytic amounts of synthetic metalloporphyrinates to give epoxides and alcohols from olefins and alkanes. Tetraphenylporphinatoiron(III) chloride (TPPFeCl) catalyzed the ...
Separation of urinary catecholamines and catecholamine metabolites by high-pressure liquid chromatography
(Elsevier, 1980-06)
A series of high-pressure liquid chromatographic (hplc) procedures are described for the separation of all major and most minor catecholamine metabolites present in human urine. The amines and metabolites are first ...
