  • Lysophospholipase of germinating barley seeds

    Creator:
    Fujikura, Yuzo
    Abstract:
    The amylose component of cereal starch contains lysophospholipid, predominantly lysophosphatidylcholine (LPC) as inclusion complexes. As starch undergoes degradation by amylases during barley germination, lysophospholipase (LPL) an enzyme which degrades lysophospholipids appears in the starchy endosperms and becomes associated with the starch fraction. The enzyme has been reported to have a...

  • Characterization of different forms of lysophospholipase in barley

    Creator:
    Lundgard, Robert
    Abstract:
    During barley germination, α-amylase and other hydrolases are synthesized in the aleurone layer and secreted into the starchy endosperm. As starch is degraded by amylases, lysophospholipids are released from inclusion complexes with the starch and undergo hydrolysis by a lysophospholipase (LPL) activity. Studies with embryo-free half seeds and isolated aleurone...

  • Environmental influences on monoterpenes and phenolics of Mentha piperita

    Creator:
    Yao, Cheng C.
    Abstract:
    Vegetatively propagated peppermint (Mentha piperita L., cv. Black Mitcham) was used to determine the effects of night temperatures (8°C vs 25°C) on the plant growth in terms of fresh weight and leaf area, and on metabolite contents. The plants were sampled after 14 days, 21 days and 28 days in...

  • Cytokinin antagonists and antibiotics related to nalidixic acid : effects on Phaseolus and Nicotiana callus tissues

    Creator:
    Marsden, Katherine E.
    Abstract:
    The effects of five cytokinin antagonists on the growth of cytokinin-autonomous lines of Phaseolus lunatus cv. Kingston, Phaseolus vulgaris cv. Great Northern, and Nicotiana tabacum cv. Wisconsin 38 callus tissues have been compared. The antagonists tested included four N⁴-substituted 4-amino-2-methylthiopyrrolo[2,3-d]pyrimidines bearing the following N⁴ side chains, 4-n-pentyl- (ms²pnN⁴Prp), 4-n-hexyl- (ms²HxN⁴Prp),...

  • Control of cytokinin autonomy in Phaseolus lunatus callus cultures

    Creator:
    Kim, Sang-Gu
    Abstract:
    The ability of N,N'-diphenylurea (DPU) to substitute for cytokininactive adenine derivatives in promoting callus growth of Phaseolus lunatus and Nicotiana tabacum has been examined. In general, DPU stimulated callus growth of P. lunatus at high concentrations and the growth of most callus tissues was irregular, while the response of tobacco...

  • The metabolic fate of lipoprotein cholesterol in isolated rat liver parenchymal cells

    Creator:
    Elzoheiry, Azza A.
    Abstract:
    The metabolic fate of cholesterol delivered to rat hepatocytes by rat plasma lipoproteins was determined. Binding and degradation of rat low and high density lipoproteins (LDL and HDL) in rat hepatocytes were studied. ¹²⁵I-labelled LDL and HDL were incubated with cells in the presence of varying concentrations of unlabelled lipoproteins...

  • Factors affecting the activation of rabbit muscle phosphofructokinase by actin

    Creator:
    Kuo, Huey-ju
    Abstract:
    The consistent application of phosphatase inhibitors and a novel final purification step using a connected series of DE-51, DE-52, and DE-53 anion exchange chromatography columns facilitate the preparation of electrophoretically homogeneous sub-pupulations of rabbit muscle phosphofructokinase which differ in their catalytic properties and endogenous covalent phosphate contents. A band of...

    Lowy, Robert Joel
    Abstract:
    A method for isolating the salt gland (SG) from the larval brine shrimp has been developed. This extra-renal organ is removed from 5-10% of Stage Inauplii by vortexing after incubating the animals at 37°C for 8 hours in a saline solution buffered with 100 mM sodium phosphate at pH 7.6....

  • An evaluation model for international short-term training programs in small-scale fisheries

    Creator:
    Martinson, Steven Eric
    Abstract:
    The purpose of this study was to propose a model for evaluating international short-term training programs in small-scale fisheries. The study focused on providing useful information to decision-makers of the program funding agency and the training program operator. The proposed evaluation model could also prove useful for other technically-oriented short-term...
