  • 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...

  • A microcomputer automated anodic stripping voltammetric analyzer for trace heavy metal speciation

    Creator:
    Dewald, Lamar Robert
    Abstract:
    An automated instrument based on a single-board microcomputer was developed for use in voltammetric analyses. Operator input of numerous experiment parameters allows any type of voltammetric analysis to be implemented and multiple scans to be run unattended. A three operational amplifier potentiostat is used to control the cell voltage and...

  • Measuring in situ biotransformation in BTEX-contaminated groundwater

    Creator:
    Alumbaugh, Robert E.
    Abstract:
    Benzylsuccinate (BSA), methylbenzylsuccinate (methylBSA), and ethylbenzylsuccinate (ethylBSA) are unambiguous anaerobic biotransformation products from toluene, xylenes, and ethylbenzene decay, respectively, and may be used to indicate intrinsic bioremediation is occurring at hydrocarbon-contaminated sites. In order to improve upon current methods that detect and quantify anaerobic hydrocarbon metabolites in field samples, solid-phase-extraction...

  • Flame ionization detection of hydrocyanic acid ; Analysis of trace aqueous solutions

    Creator:
    Claeys, Robert Raymond
    Abstract:
    A gas chromatographic procedure was developed for the determination of nanogram quantities of hydrocyanic acid using a flame ionization detector. Excellent chromatograms were obtained on a porous polyaromatic polymer column (Porapak Q) at 60°C. The procedure was employed for the analysis of HCN in aqueous cyanide solutions. Solutions as low...

  • Aryl acetylene substituent effects : the synthesis and application of biaryls

    Creator:
    Naffziger, Michael R.
    Abstract:
    The work described herein details the synthesis and application of biphenyls that probe the effects of hydrogen, Cl / Br, and methyl substituents on the aryl ring of the terminal acetylenic carbon. From this work, we successfully developed the rapid synthesis of phenyl acetylenes in 3-4 steps from inexpensive commercially...

  • Some biochemical studies of phenylmercuric acetate and mercuric acetate toxicity in rats

    Creator:
    Ellis, Robert William
    Abstract:
    Biochemical studies of phenylmercuric acetate (PMA) and mercuric acetate toxicity in rats carried out during this investigation were (1) the metabolism of ²⁰³Hg(Ac)₂ and ²⁰³Hg-PMA within kidney and liver tissues following oral ingestion, (2) the effect on some soluble enzyme activities and determinations of ²⁰³Hg binding in the enzyme fractions,...

  • 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...

  • Preparation and properties of polyglycyl insulin

    Creator:
    Wu, Lily Henson Liu
    Abstract:
    In order to understand more about insulin behavior in solution, Zn-free insulin was modified by adding polyglycyl chains to the molecule and then observing the effect of the peptide on the behavior of insulin under various conditions. NCA-glycine (N-Carboxyglycine anhydride) of high purity was reacted with Zn-free insulin in aqueous...

  • An investigation of the thermal stability of polyglycyl bovine serum albumin

    Creator:
    Harris, Ward Edwin
    Abstract:
    A heat stable derivative of bovine serum albumin containing 300 residues of glycine added to 30 sites on the surface of the protein has been prepared. This derivative may be heated to 100° C for prolonged periods of time without aggregation. By comparison, native BSA aggregates at 62° C under...

  • Preparation and comparative solubility of poly-L-tyrosyl lysozyme and poly-O-methyl-L-tyrosyl lysozyme

    Creator:
    Venier, Lynn Corrine
    Abstract:
    In order to examine some possible tyrosyl interactions, poly-tyrosyl lysozyme and poly-O-methyltyrosyl lysozyme were prepared and their solubilities were compared. Both derivatives exhibited similar pH dependent solubilities, showing a minimum solubility at about pH 8. Their solubilities varied with temperature, having a positive enthalpy of solution. The effect of a...
