  • Pathways of glucose utilization and ribose synthesis in the chick embryo

    Creator:
    Coffey, Ronald Gibson
    Abstract:
    The production of C¹⁴O₂ metabolized from glucose labeled in specific carbon atoms by homogenates of chick embryonic and adult heart was compared by the radiorespirometric technique. Homogenates of early (two to five days of incubation) embryo hearts were found to utilize the phosphogluconate pathway of glucose catabolism to a greater...

  • Protein synthesis in Sarcophaga bullata

    Creator:
    Allen, Robert Roy
    Abstract:
    An investigation was made into certain aspects of protein synthesis at different developmental stages of the flesh fly Sarcophaga bullata. This included measurements of the incorporation of labeled amino acids into protein by intact cells from a single organ, the larval fat body, and a study of amino acid activating...

  • Carnitine and derivatives in embryonic chick tissues

    Creator:
    Casillas, Edmund Rene
    Abstract:
    Carnitine, acetylcarnitine, and long-chain acylcarnitine concentrations were determined for heart, brain, and liver of chick embryos during various stages of development. The total carnitine concentration was approximately the same in all three organs and showed only small variations during development. Acetylcarnitine was not detected in any organ until the seventeenth...

  • Deoxyribose-phosphate aldolase and the biosyntheiss of DNA in the chick embryo

    Creator:
    Anderson, Martin Michael
    Abstract:
    The activity of deoxyribose-phosphate aldolase was determined in chick embryo brains, hearts and livers during the course of development. Assays were made in the direction of synthesis of deoxyribose-5-phosphate. Low levels of activity in the brain and heart remained constant throughout the course of development. Activity in the liver expressed...

  • The effects of actinomycin D on the primary and secondary immune responses induced in vitro

    Creator:
    Thompson, William Carl
    Abstract:
    In order to assess the importance of RNA synthesis in the induction and antibody-producing phases of immune responses, actinomycin D was used to inhibit the primary and secondary in vitro immune responses of mouse spleen cells against heterologous erythrocytes. The presence of actinomycin D (0.1 or 0.125 μg /ml) throughout...

  • Kinetics of synthesis and degradation of chicken liver xanthine dehydrogenase

    Creator:
    Epstein, Arnold
    Abstract:
    The role of synthesis and degradation in controlling enzyme concentrations was studied. Concentrations of chloride and arginine were determined for blood and liver at various stages of development from the embryo to the 8 day old chicken. The chloride concentrations were used to obtain the volume of extracellular blood in...
