Infrared method for determining circadian patterns of carbon dioxide release
(Springer-Verlag, 1969-06)
Using an infrared technique based on the continuous monitoring of a characteristic infrared absorption band, temporal variations in the circadian patterns of carbon dioxide release were examined in two species of noctuid ...
Chromosome number in the lizard genus Uta (family Iguanidae )
(Springer-Verlag, 1968-12)
A chromosome number of 34 (12 macro- and 22 microchromosomes) was found to be characteristic of the bone marrow in 47 animals including males from the species Uta antiquus , and both males and females from the following ...
Changes in enzymes regulating isocitrate breakdown in neurospora crassa
(Springer-Verlag, 1965-06)
1. Crude homogenates from Neurospora crassa grown on varions concentrations of sucrose and acetate were assayed for enzymes regulating isocitrate breakdown.
Substrate-induced dissociation of rabbit muscle aldolase into active subunits
(Elsevier, 1967-11-17)
Direct demonstration of superoxide anion production during the oxidation of reduced flavin and of its catalytic decomposition by erythrocuprein
(Elsevier, 1969-09-10)
The oxidation of reduced flavins by molecular oxygen at neutral to alkaline pH produces substantial yields of the superoxide anion, . This species is rapidly destroyed by catalytic quantities of the copper protein, ...
Genetic and population studies of quantitative levels of adenosine triphosphate in human erythrocytes
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1967-06)
The mean content of ATP in red cells of American Negroes is significantly less than the mean level in American Caucasians. This is compatible with the hypothesis that the quantitative level of ATP in red cells may be ...
Zoosporic marine fungi from the Pacific Northwest (U.S.A.)
(Springer-Verlag, 1969-06)
An investigation of the zoosporic fungi in the vicinity of the Friday Harbor Laboratory, San Juan Is., Washington, revealed the presence of great numbers of fungi. With one exception ( Olpidium sp. ) these were all ...
Oxygen transfer mechanisms in the gluconic acid fermentation by Pseudomonas ovalis
(Wiley Subscription Services, Inc., A Wiley Company, 1964-09)
The oxygen uptake rate to suspended cells of Pseudomonas ovalis was measured in two ways using the same cell suspension. Initially the rate was found by measuring the rate of production of gluconic acid by cells suspended ...
