(Elsevier, 1958)
Paresis strikes most frequently during life's most productive years. It is seen approximately three times as frequently in males as females, and over twice as frequently in whites as in Negroes. The usual incubation period ...
The metabolism of Brucellae: The nature of the effects of pH and concentration on the rate of oxidation of succinate
(Elsevier, 1956-10)
The sharp rise in the rate of oxidation of succinate by Brucella abortus that occurs with gross increases in hydrogen ion or the substrate concentration was accompanied by an even greater degree of increase in the rate of ...
The infrared and Raman spectra of the pentafluoroethyl halides
(Elsevier, 1959)
The infrared spectra of the pentafluoroethyl halides have been investigated in the gaseous state with double-beam prism spectrometers using NaCl and CaF2 prisms, and the Raman spectra of the compounds have been obtained ...
Peptic hydrolysis of ovalbumin modified by acetylation,
(Elsevier, 1957-09)
1. 1. Two types of acetylated ovalbumin derivatives designated as N-and N,O-acetylovalbumin were prepared by treatment with ketene at pH's 5.6 and 9.0, respectively.2. 2. Both limited and extensive acetylation decreases ...
A method for the determination of guanidoacetic acid and arginine in biological fluids,
(Elsevier, 1959-12)
A method for the determination of either arginine or guanidoacetic acid or both in biological materials has been presented. The method is based on the chromatographic separation of arginine from guanidoacetic acid and the ...
Synthesis of B vitamins by excised parts of White lupine seedlings grown in sterile culture
(Elsevier, 1954-09)
In this investigation it has been found that excised roots, hypocotyls, and epicotyls of White lupine seedlings synthesize thiamine, riboflavin, and niacin when grown in sterile cultures. Oxygen is necessary for this synthesis.
A Comparison of Different Criteria for Determining the Effects of Antibiotics on Tetrahymena pyriformis E. *
(Blackwell Publishing Ltd, 1955-05)
A study was made of the effects of Chloromycetin, Aureomycin and Terramycin on growth of Tetrahymena pyriformis E. Growth was measured by turbidimetry, cell count and cell volume. Data were analyzed to compare growth rates, ...
The development of tyrosinase and cytochrome oxidase activity in mutants of Glomerella cingulata
(Elsevier, 1953-07)
Cytochrome oxidase activity in the standard type and in four mutants of Glomerella cingulata has been shown to be constant throughout the mycelial development. This enzyme is concentrated on mitochondria-like particles ...
Infrared spectra of high polymers : Part IX. Polyethylene terephthalate
(Elsevier, 1959)
Infrared spectra of polyethylene terephthalate and three of its deuterated analogs have been obtained in the region of 70 to 3600 cm-1, polarized spectra having been obtained down to 330 cm-1. On the basis of analysis of ...
Behavioral effects of chronic administration of psychoactive drugs to anxious patients
(Springer-Verlag, 1959-03)
The effects of chronic administration of (a) 1600 mg. meprobamate, (b) five Tranquil tablets (the maximum recommended daily dose), and (c) placebos were examined, in a counterbalanced partially blinded design. Thirty-two ...
