  • Oxidative Stress Response Genes: A Circadian Connection?

    Creator:
    McAllister, Marisa C.
    Abstract:
    Circadian clocks are internal mechanisms regulating many physiological processes. Research suggests that the circadian clock may regulate repair of cellular damage caused by reactive oxygen species (ROS), but molecular pathways from the clock to ROS repair are not known. The gene cncC, known in mammals as Nrf2, and its repressor...

  • Demonstration of an Alginate Valve in a Paper Microfluidic Device

    Creator:
    Cornwell, David Q.
    Abstract:
    Paper microfluidic devices are capable of processing fluids using capillary flow in materials that are lower cost than the standard materials used in microfluidics. Due to the low cost of their fabrication and minimal requirements for instrumentation, paper microfluidic devices are ideal for use in low-resource settings. They have the...

  • Gene expression in the peripartum canine placenta

    Creator:
    Fellows, Elizabeth Jane
    Abstract:
    This research investigated gene expression in the canine placenta during the peripartum period. Previous studies have recognized molecular changes that occur in the placenta around the time of placental release in other species, but no study has looked at gene expression in the late gestation canine placenta. Of particular significance...

  • Adaptation to long-term osmotic stress in a domesticated Saccharomyces cerevisiae strain

    Creator:
    Holman, Douglas S.
    Abstract:
    Osmotic stress is a common challenge faced by organisms in environments with variable salinity or aridity. Understanding the evolutionary mechanisms underlying adaptation to osmotic stress may have wide applications, including management of populations experiencing climate change, or engineering industrial organisms involved in processes such as fermentation. While Saccharomyces cerevisiae is...

  • Soil arthropods in the Central Cascades : slash burning effects and biology of some species

    Creator:
    Estrada-Venegas, Edith G
    Abstract:
    Despite the recognized role of soil arthropod fauna on nutrient cycling and decomposition processes, many aspects of the effects of sylvicultural methods in forest ecosystems upon their biology remain poorly understood. The long term effects of prescribed fires on soil arthropods in forest ecosystems in the Pacific Northwest have never...

  • The influence of light intensity on the phytochemistry of Chrysolepis chrysophylla (Fagaceae) and the relationship to the herbivory of Habrodais grunus herri (Lycaenidae)

    Creator:
    Bowden, Richard I.
    Abstract:
    Defensive chemical and nutritive quality of young leaves were measured for 72 individual trees of Chrysolepis [Castanopsis] chrysophylla in conjunction with light intensities of two different stand types and population numbers of Habrodais grunus herri in the Cascade mountains of Oregon. Leaves were collected in the spring and leaf characteristics...

  • Three Sites are Better than One : Exploring Multivalency in LC8 Binding Partners

    Creator:
    Clark, Sarah A.
    Abstract:
    Hub proteins bind a large number of partners to facilitate structural changes and downstream protein interactions. LC8, a highly conserved protein homodimer, is a unique hub that regulates the activity of proteins in a wide range of cellular processes by binding to intrinsically disordered regions. With many of these systems,...

  • How do engineering students develop and reason with concepts of electricity within a project-based course?

    Creator:
    Bledsoe, Karen E.
    Abstract:
    Reform in science education has often emphasized task-based learning as an instructional method to improve student understanding and retention of concepts, and to promote the development of reasoning and problem-solving. Yet studies assessing student knowledge at the beginning and end of a task-based class show mixed results. Students in task-based...

  • Cellular characteristics of canine trophoblasts

    Creator:
    Sahlfeld, Laura
    Abstract:
    This research investigated the development of a novel canine model to study preeclampsia. Normal canine placental development has morphologic and histologic similarities to the shallow trophoblast invasion occurring with preeclampsia in humans, which makes the dog a particularly good choice for modeling this disease and will be an improvement on...

  • Roles of homeodomain transcription factors during organogenesis

    Creator:
    Xu, Jun
    Abstract:
    The spatial and temporal patterning of sequence specific transcription factors (SSTFs) contributes to cell type specification and organ formation during embryogenesis. Homeodomain transcription factors are evolutionally conserved among invertebrate and vertebrate animals. They are responsible for body segmentation and organogenesis. Lbx1 and Pitx2 both are homeodomain transcription factors contributing to...
