(Elsevier, 1957)
One thousand one hundred and seventy-nine cases of leukemia in persons over the age of 13 years seen at the Simpson Memorial Institute of the University of Michigan, from 1927 through 1956, have been reviewed.Seven hundred ...
Mammalian tyrosinase: Effect of ions on enzyme action
(Elsevier, 1952-04)
1. 1. The univalent cations Li+, Na+, K+, and NH4+ have no effect on tyrosinase action.2. 2. The anions, fluoride, chloride, acetate, and oxalate, consistently inhibit the tyrosine-tyrosinase and dopa-tyrosinase reactions. ...
Sarcosine oxidase activity of rat liver tissue: Effect of folic acid deficiency and induced hyperthyroidism
(Elsevier, 1952-11)
The sarcosine oxidase content of hepatic tissue from rats made deficient in folic acid was similar to that of normal rats. This is taken as evidence that sarcosine oxidase activity is not dependent upon the presence of ...
A method for the determination of the electrophoretic patterns of hemolyzed mouse sera
(Elsevier, 1951-05)
A method is presented that will give comparable results for the evaluation of electrophoretic data on hemolyzed mouse serum patterns. Not only may hemoglobin be determined in the serum, but its contribution to the total ...
Factors influencing xanthine oxidase activity in rat skin
(Elsevier, 1955-05)
1. 1. A method is described for preparing skin extracts which show reasonably consistent xanthine oxidase activities.2. 2. Levels of xanthine oxidase in skin do not change significantly during the first 21 days after birth. ...
Studies of the biosynthesis of protein and ribonucleic acid in HeLa cells infected with poliovirus
(Elsevier, 1959-02)
The amounts of protein, RNA (ribonucleic acid), virus, and the rate of incorporation of P32 into RNA were determined in various subcellular fractions of HeLa cells at various times during a single sequence of infection ...
Studies on relationships between actinophage and variation in Streptomyces: I. Morphology of phage production and lysis in a streptomycete carrying a temperate phage
(Elsevier, 1956-04)
The relationship of phage production to lysis and variation in a streptomycete carrying temperate phage was investigated. Macroscopically, the original isolate, S-77, produced cartilaginous mycelial growth characteristic ...
Genetic Studies of the Pyridoxine Mutant in Variety Two of Tetrahymena pyriformis *
(Blackwell Publishing Ltd, 1958-11)
When two strains cf T. pyriformis that do not require exogenous pyridoxine are crossed, all progeny grow without the vitamin. Offspring from crosses of two pyridoxine requiring clones require pyridoxine with the exception ...
