  • Upper Cretaceous through Eocene stratigraphy of the southern Ventura basin, California

    Creator:
    Seedorf, Douglas Christopher
    Abstract:
    Surface and subsurface data indicate that Cretaceous strata in the southern Ventura basin are part of the northward prograding Chatsworth submarine fan. The fan extends westward as far as Trancas Beach in the Santa Monica Mountains and wells in the Oxnard Plain and on Oak Ridge. The eastern edge of...

  • Coordinated regulation of plasma membrane lipids in Saccharomyces cerevisiae

    Creator:
    Low, Christopher S. F.
    Abstract:
    Plasma membranes isolated from a yeast sterol auxotroph (RD5-R) grown on 1,5, and 15 pg m1⁻¹ exogenous concentrations of sterol showed no discontinuity in plots of steady-state fluorescence anisotropy. Liposomes constructed from phospholipid and sterol extracted from RD5-R grown on different sterols indicated exogenously supplied sterol modulated cellular phospholipids such...

  • DNA precursor compartmentation in mammalian cells : distribution and rates of equilibration between nucleus and cytoplasm

    Creator:
    Leeds, Janet M.
    Abstract:
    A rapid nuclear isolation technique was adapted in order to examine the question of DNA precursor compartmentation in mammalian cells. By using this method a reproducible proportion of the cellular nucleotides remained associated with the isolated nuclei. Examination, at several different cell densities, of exponentially growing HeLa cells showed that...

  • The effects of different otolith ageing techniques on estimates of growth and mortality for two species of rockfishes, Sebastes pinniger and Sebastes diploproa

    Creator:
    Wilson, Christopher D.
    Abstract:
    The use of some age determination methods may result in the incorrect age structure of fish populations. This in turn may lead to incorporation of inappropriate data into models used for stock management. Otoliths are commonly used for determining the age of fishes, and ages based on the whole otoliths...

  • Characterization of putative recognition components of echinoderm coelomic fluid: agglutinins in Strongylocentrotus purpuratus

    Creator:
    Pierce, Laura G.
    Abstract:
    Due to an interest in the evolutionary origins of vertebrate mechanisms of immunorecognition, researchers have frequently turned to deuterostome invertebrates as model organisms. The purple sea urchin, Strongylocentrotus purpuratus (Echinodermata: Echinoidea), was selected for this study of putative immunorecognition molecules in a deuterostome invertebrate. Hemagglutinins, molecules which agglutinate red blood...

  • Alternatives to the DNA precursor-synthesizing enzyme complex hypothesis

    Creator:
    Weitz, Stephen L.
    Abstract:
    Investigators have been studying an aggregate containing enzymes of deoxyribonucleoside triphosphate biosynthesis in T4-phage infected bacteria. They suggest that it behaves as an organized complex, efficiently channeling DNA precursors to the replication apparatus. Previous work has suggested that about 10 enzyme activities remain associated through several fractionation steps. This multi-enzyme...

  • Bacterial clearance in the sea urchin, Strongylocentrotus purpuratus

    Creator:
    Yui, Mary A.
    Abstract:
    Characteristics of bacterial clearance were investigated in the purple sea urchin, Strongylocentrotus purpuratus (Echinodermata: Echinoidea). Primary clearance kinetics were determined for three bacteria, a marine Gram negative motile rod, a marine Gram positive non-motile rod, and a fresh water fish pathogen, Aeromonas salmonicida. Various doses of live bacteria were injected...

  • Attempted cloning of T4 phage ribonucleotide reductase

    Creator:
    Booth, Joseph
    Abstract:
    Ribonucleotide reductase is an important enzyme in the control of DNA replication within the cell. Ribonucleotide reductase exerts its control through enzymatic reduction of nucleoside diphosphates. The bacteriophage T4 enzyme is an example of the class of iron-requiring reductases which also includes E. coli and mammalian ribonucleotide reductases. The two...

  • Neural regulation of immunity in teleosts

    Creator:
    Flory, Craig M.
    Abstract:
    It has long been observed that stress can increase our susceptibility to infectious diseases and cancers. Recent experimental evidence suggests that this increased susceptibility is due to suppression of immunity. A variety of neuroendocrine products are released during periods of stress, and a large number of these are now known...

  • Bacteriophage T4-coded dihydrofolate reductase : cloning and structural analysis of its gene and organization of flanking regions

    Creator:
    Purohit, Sarla
    Abstract:
    The dihydrofolate reductase gene of bacteriophate T4 has been investigated at the structural level to elucide the unusual regulation of expression of this gene and possible evolutionary relationships between the ohage and drug resistance factors-encoded dihydrofolate reductases (DHFR). A 1.1-kilobase-pair restriction fragment of the T4 multiple mutant dec8 containing frd,...
