The effects of scopolamine hydrobromide on one-way and two-way avoidance learning in rats
(Elsevier, 1968-09)
Previous studies have shown certain striking similarities between the behavioral effects produced by some anticholinergic drugs and the effects produced by hippocampal destruction. To investigate this parallel more thoroughly, ...
Species differences in the eeg response to epinephrine, 5-hydroxytryptamine and nicotine in brainstem transected animals,
(Elsevier, 1963-06)
Species differences have been observed in the EEG activation response to intravenous epinephrine, 5-hydroxytryptamine, and nicotine in rabbits, cats, dogs and monkeys. It was also found that a relatively high level of ...
Distribution of [alpha]-aminoisobutyric-C14 acid in rats deficient in thiamine, pantothenate, fatty acids, or potassium
(Elsevier, 1965-08)
A nutritional deficiency of fatty acids in young rats resulted in a marked elevation of the steady-state serum level of an injected dose of [alpha]-aminoisobutyric acid, and in a decrease in the transport of this model ...
A new, sensitive determination of phosphate
(Elsevier, 1969-07)
A new method for the determination of phosphorus using Triton X-100 instead of reducing agents is more sensitive than procedures described earlier. Organic phosphate esters do not appear to interfere with the determination ...
Electron diffraction study of gaseous tetrahydrofuran
(Elsevier, 1969)
The gas phase molecular structure of tetrahydrofuran has been reinvestigated. Experimental diffraction intensities are well accounted for by a freely pseudo-rotating molecule. The mean value of the pseudo-rotational puckering ...
Metabolism of dehydroepiandrosterone and dehydroepiandrosterone sulfate in tissue extracts of rabbit ovaries
(Elsevier, 1969-02)
The simultaneous incubation of 3H-dehydroepiandrosterone sulfate and 14C-dehydroepiandrosterone by soluble and microsomal extracts of rabbit ovaries was investigated. 3H-dehydroepiandrosterone sulfate was converted to ...
Hydrostatic pressure effects on rabbit and echinoderm myosin ATPase
(Elsevier, 1969-06)
When saturated with ATP, sea cucumber myosin hydrolyzes ATP about 15 times more slowly than rabbit myosin, as expected from the slower contraction time of the muscle. The Arrhenius plots coincide at low temperatures, but ...
