  • Enzymatic studies of the prenatal chick, with special reference to the multibple forms of liver soluble NADP-linked isocitric dehydrogenase

    Creator:
    Cheung, Geoffrey Peter
    Abstract:
    Levels of activity of glucose-6-phosphate- , 6-phosphogluconate- , and isocitric- dehydrogenase were measured in the soluble and particulate fractions of heart, brain and liver at several ages throughout the development of the chick embryo. Compared to isocitric dehydrogenase, levels of glucosesphosphate- , and 6-phosphogluconate- dehydrogenase are generally low. This suggests...

  • Nutritional muscular dystrophy production and pectoral muscle 5'-nucleotidase activity in the chick

    Creator:
    Roffler, Sheila Ann
    Abstract:
    In an attempt to find a laboratory species which develops an experimental myopathy similar to white muscle disease (WMD) in lambs, comparative studies of nutritional muscular dystrophy of chicks were initiated. This condition was grossly visible as white striations running parallel with the fibers of the pectoral muscles and was...

  • Synthesis of some bicyclo[6.1.0] - nonane derivatives

    Creator:
    Wall, Robert Gene
    Abstract:
    Bicyclo [6.1.0] non-4-ene was prepared by two routes; (1) reaction of cis-cis-1, 5-cycloöctadiene with methylene iodide and zinc-copper couple, (2) sodium-methanol reduction of 9, 9-dibromobicyclo-[6.1.0] non-4-ene. The bicyclononene was characterized by its infrared spectrum, nuclear magnetic resonance spectrum and common physical properties. The olefin was hydrogenated to bicyclo [6.1.0] -...

  • Methanolysis of tetrakis(trichlorophosphine)nickel(0)

    Creator:
    Bachman, David Franklin
    Abstract:
    The methanolysis of phosphorus trichloride coordinated to nickel (0) has been studied. Free phosphorus trichloride reacts with methanol to give dimethyl hydrogen phosphonate, methyl chloride, and hydrogen chloride. The reaction involves a rearrangement on phosphorus using the lone pair, in which the coordination number increases from three to four. In...

  • Steroid dialkylcarbene reactions

    Creator:
    Dixon, Dale David
    Abstract:
    Steroid carbenes have been investigated as synthetic intermediates. Basic decomposition of 4-en-3-one tosylhydrazones (and other A-ring systems) gives varying amounts of 2, 4-dienes, and solvent derived products with diglyme, heptane, tetrachloroethylene, carbon tetrachloride, benzene and cyclohexene. A method for separating complex product mixtures was developed and a study of the...

  • Dihalocarbene reactions with steroid olefins

    Creator:
    Cornelia, Richard Hartman
    Abstract:
    Dihalocarbenes have been generated mainly by thermal decomposition of sodium trihaloacetate and phenyl (trihalomethyl)mercury, and give gem-dihalocyclopropyl adducts with various steroid olefins. A new procedure involving the use of sealed tubes makes possible the addition of dihalocarbenes to sterically hindered olefins. In this manner, 7-cholestenyl benzoate when treated with PhHgCC1₃...

  • The diffusion coefficient of propane in helium

    Creator:
    Tang, Fa-tai
    Abstract:
    A specially designed gas chromatograph with both TCD and FID has been tested for the measurement of the diffusion coefficients of methane and propane in helium. Knox's arrested elution technique(⁴) was used and yielded a value of 0.6431 cm²/sec averaged with the value obtained by Yang and Hawkes(⁷). Values of...

  • A study of photon counting employing a double-beam digital photometer

    Creator:
    Ash, Kenneth Carl
    Abstract:
    A double-beam photometer was designed and built employing photon counting to give a direct digital readout. It was evaluated as an analytical instrument with special emphasis on pulse recovery time, pulse interaction and instrument settings. An equation is developed to explain pulse interaction in event counting systems.
