Thermal adjustments in cardiac and skeletal muscles of lizards
(Springer-Verlag, 1969-03)
1. Isometric twitch tension development was measured over a wide range of temperatures in skeletal and cardiac (ventricular) muscles from diverse Australian lizards representing several families and including both diurnal ...
The effect of brainstem transection on blood pressure in the dog
(Elsevier, 1969-03-01)
Blood pressure was compared before and after midpontine pretrigeminal brainstem transection in the dog. Statistically significant decreases in blood pressure were observed 1/2, 1, and 1-1/2 hours after brainstem transection. ...
Biosynthesis of alkyl-ether containing lipid from dihydroxyacetone phosphate
(Elsevier, 1969-10-22)
A lipid, stable to alkaline methanolysis, is formed when liver mitochondria or brain microsomes are incubated with dihydroxyacetone phosphate, long chain alcohol, ATP, CoA, NaF and Mg++. The lipid has been identified as ...
The chemical synthesis of 2-keto-3-deoxy-octonate and its cleavage by a specific aldolase
(Elsevier, 1963-05-22)
We have previously reported (Heath and Ghalambor, 1963) the occurrence of 2-keto-3-deoxy-octonate (KDO) as a glycosidically-bound constituent of cell wall lipopolysaccharide (LPS) of 0111-B4 and the enzymatic synthesis ...
Synthesis and maturation of phage P22 DNA : II. Properties of temperature-sensitive phage mutants defective in DNA metabolism
(Elsevier, 1968-06-28)
Three temperature-sensitive mutants of phage P22 have been isolated which are defective in phage DNA metabolism. After infection at restrictive temperature, one mutant (ts 12.1) fails to synthesize measurable quantities ...
The amino acid substitution and some chemical properties of a variant human erythrocyte carbonic anhydrase: Carbonic anhydrase Id Michigan
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1967-09)
Carbonic anhydrase Id Michigan , an electrophoretic variant of human red cell carbonic anhydrase I, was purified from erythrocytes obtained from an individual heterozygous for the trait. Primary structural analysis indicates ...
The structures of the glia and of the synapses in the sympathetic chain of man
(Springer-Verlag, 1960-07)
Del Rio Hortega teilte die Glia der sympathischen und spinalen Ganglien in 2 Gruppen ein: 1. die perisomatische Glia, welche das Perikaryon der Parenchymzellen mit 2 übereinandergelagerten Schichten umgibt und 2. periaxonale ...
Effect of tetranitromethane on the aldolase and [beta]-decarboxylase activities of bovine liver 2-keto-4-hydroxyglutarate aldolase
(Elsevier, 1969-09-10)
Treatment of bovine liver 2-keto-4-hydroxyglutarate aldolase with tetranitromethane at pH 8.0 and room temperature rapidly and irreversibly destroys two known catalytic properties of this enzyme, namely, the reversible ...
Factors limiting microbial activities in soil. II: The effect of sulfur
(Springer-Verlag, 1961-12)
The only nutrient element other than nitrogen and phosphorus which limited microbial activity in a sandy soil was sulfur. The addition of extremely small quantities of MgSO 4 , ranging from 0.32 to 1.6 mg sulfur/100 g soil, ...
Studies on the rate of spermatogenesis in Drosophila effects of X-rays and streptonigrin
(Springer-Verlag, 1965-03)
1. The rate of spermatogenesis in adult Drosophila melanogaster was measured by use of tritiated thymidine as a radioactive tracer. Three experimental groups existed: control, irradiated, and streptonigrin-treated males.
