Immunological perspectives of a host-parasite system : studies on the humoral and cellular components of Biomphalaria glabrata, New World host for Schistosoma mansoni

Creator:: Boswell, Carl A.
Abstract:: The host snail Biomphalaria glabrata and the parasitic trematode Schistosoma mansoni are valuable subjects for studies evaluating and defining immunological parameters that determine the outcome of individual host-parasite encounters. In this thesis, both soluble and cellular components of the snail's hemolymph were examined to gain insight into the basis for...

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...

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...

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...

Organization of T4 bacteriophage genes and gene products involved in DNA precursor biosynthesis

Creator:: Wang, Yeong
Abstract:: Bacteriophage T4 gene 42 encodes dCMP hydroxymethylase, an enzyme unique to the deoxyribonucleotide metabolism of T-even bacteriophages. To study biochemical and biophysical properties of the enzyme, as well as the interaction of dCMP hydroxymethylase with other DNA precursor biosynthetic enzymes in vitro, availability of large amounts of the enzyme is...

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...

DNA precu[r]sor compartmentation in mammalian cells : metabolic and anti-metabolic studies of nuclear and mitochondrial DNA synthesis

Creator:: Bestwick, Richard Keith
Abstract:: This dissertation describes an investigation of DNA precursor supply for mitochondrial and nuclear DNA synthesis in HeLa cells and Mouse L-cells. HeLa cells were used for the quantitation of cellular and mitochondrial deoxyribonucleoside triphosphate (dNTP) and ribonucleoside triphosphate (rNTP) pools and of changes in pools in response to treatment with...

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...

Deoxyribonucleotides as determinants of DNA replication fidelity in bacteriophage T4

Creator:: Sargent, Roy Geoffrey
Abstract:: Imbalanced deoxyribonucleoside triphosphate (dNTP) pools are mutagenic for DNA synthesis in both intact cells and cell-free replication systems. Almost certainly, such mutagenesis involves competition between correctly and incorrectly base-paired precursors at replication sites. However, there are certain differences between the intact cell and cell-free systems that do not always allow...

Methodological considerations for implementing the U.S. Soil Conservation Service Land Evaluation and Site Assessment (LESA) System in Oregon, with special reference to Marion County, Oregon

Creator:: Fastner, Christopher John
Abstract:: Oregon land use specialists believe that the present definitions of farm and forest land in the state planning goals are too broad. This results in poor quality resource lands being as strongly protected as those of top quality. With persistent growth pressure on rural lands, a means to distinguish among...
