Repression of DNA Mismatch Repair (MMR) in Arabidopsis thaliana through Dominant-Negative MMR Proteins

Creator:: Mohamed, Aly
Abstract:: The highly conserved multi-protein mismatch repair (MMR) system is known for its ability to correct post replication errors in genomic DNA. A hallmark of MMR deficiency in all organisms is microsatellite instability. The initiating proteins in the eukaryotic MMR system are hetrodimers formed with an integral MSH2 subunit and one...

Factors Contributing to the Development of Body Fat In Growing Boys and Girls

Creator:: Lovemark, Courtney
Abstract:: The prevalence of overweight and obesity in children and adolescents continues to rise and is considered a major public health problem. The aim of this investigation was to evaluate the contributions of sport participation, and calcium intake (controlling for mean energy intake, sex, and maturation status) on the development of...

Identification of Small Molecule Inhibitors of the Staphylococcus aureus Sortase A Enzyme

Creator:: Bateman, Katherine B.
Abstract:: The Sortase A (SrtA) enzyme is a potential target for a new class of anti-infective drugs because it is responsible for anchoring virulence factors to the surface of pathogenic, Gram-positive bacteria such as Staphylococcus aureus. High throughput screening yielded low molecular weight compounds that inhibit purified SrtA from S. aureus....

Resource uptake and host tissue chemistry: Implications for competition and disease

Creator:: Schumann, Canan B.
Abstract:: Maintenance of optimal nutrient supplies is fundamental to the functioning of vertebrate, invertebrate, bacterial and plant physiology. Organisms on this planet compete with each other primarily to fulfill nutritional needs in order to maximize their health, wellbeing, and reproductive success. Here we examine nutrient concentrations in several different grass species...

Effects of Hypoxia on Survival and Growth of Barnacle Larvae Off the Oregon Coast

Creator:: Amstutz, Amanda C.
Abstract:: In recent years off the United States Oregon coast severe hypoxic events have resulted in areas of mass vertebrate and invertebrate species mortality known as dead zones. Creation of dead zones and alteration of community species composition in response to inner shelf hypoxic conditions have been observed annually from 2002...

Mutagenesis and Crystallization of Ptr ToxB, a host-selective toxin of Pyrenophora tritici-repentis

Creator:: Miles-Rockenfield, Kara B.
Abstract:: Pyrenophora tritici-repentis (Ptr) is the fungal causal agent of the disease tan spot in wheat and causes necrosis and chlorosis in infected leaves. These symptoms are caused by host-selective toxins (HSTs), molecules that serve as the sole determinants of pathogenicity. Ptr has three known HSTs, the proteinaceous Ptr ToxA and...

Location of the neutral axis in wood beams

Creator:: Holm, Sarah C.
Abstract:: It is commonly accepted that for the analysis of wood beams, the neutral axis coincides with the centroid of the beam. Although this assumption is used in analysis, wood is not an isotropic material, as it has different elastic properties in the tangential, radial and longitudinal directions, nor is it...

Microbial Abundance and Community Analysis in Devil’s Hole, Harrington Sound, Bermuda

Creator:: Denman, Carmen C.
Abstract:: Microbial activity within elevated CO2 and oxygen depleted environments changes with density driven stratification overturn in the seasonally anoxic region of Devil’s Hole, Bermuda. The temperature gradient developed during the summer months creates a natural laboratory to study bacterial and virus population density and microbial community dynamics in the anoxic...

DNA UV damage-related control of ribonucleotide reductase : possible relationship to mutagenesis and the incidence of and attitudes toward skin cancer in several western nations

Creator:: Stenberg, John C.
Abstract:: Two strains of Escherichia coli were studied to determine the effect of constitutive expression of the SOS DNA damage repair response on the activity of ribonucleotide reductase. Activity of the reductase and cellular deoxynucleoside triphosphate (dNTP) pools were both determined before and after exposure of the cells to ultraviolet radiation....
