  • In vivo assessment of nanomaterial-induced toxicity using embryonic zebrafish

    Creator:
    Usenko, Crystal Y.
    Abstract:
    Due to their unique physical, chemical, and magnetic properties, nanomaterials have great potential for industrial development. There is a pressing need to develop rapid whole animal-based testing assays to assess the potential toxicity of engineered nanomaterials. To meet this challenge the embryonic zebrafish model was employed to determine the toxicity...

  • Unraveling tissue regeneration using chemical genetics

    Creator:
    Mathew, Lijoy K.
    Abstract:
    The emerging field of regenerative medicine is mainly approached by two different aspects. First is the use of stem cell based models to generate a suite of differentiated cells for therapeutic applications and the alternative approach is to utilize the non-mammalian models that have the inherent capacity to regenerate their...

  • Assessment of fluorinated chemicals (FCs) on developmental toxicity in embryonic zebrafish

    Creator:
    Duong, Lisa
    Abstract:
    Fluorinated chemicals (FCs) have been used since the 1950s in many industrial and commercial applications because of their unique properties such as chemical inertness, resistance to heat and their ability to repel water and oils. Concerns regarding potential environmental or human health risk from FCs exposure have emerged due to...

  • The use of natural plant extracts as a feed additive to prevent laminitis in lactating dairy cows

    Creator:
    Pierson, Miranda L.
    Abstract:
    Two experiments were conducted looking at both acute and sub-acute laminitis. An acute nutritional induction model was used to examine whether blood profiles and gene expression are similar to other studies conducted using an endotoxin induction model. Twelve sheep were randomly assigned to three treatment groups which were control, 4-hour...

  • Environmental complex mixtures modify benzo[a]pyrene and dibenzo[a,l]pyrene-induced carcinogenesis

    Creator:
    Courter, Lauren A.
    Abstract:
    Human exposure to the carcinogenic polycyclic aromatic hydrocarbons (PAHs) benzo[a]pyrene (B[a]P) and dibenzo[a,l]pyrene (DB[a,l]P) is through environmental complex mixtures, such as urban dust particulate matter (UDPM) and diesel exhaust (DE), however the potency of these PAH within a mixture is not established. To determine the effect of these mixtures on...

  • Geneticist L.C. Dunn : politics, activism, and community

    Creator:
    Gormley, Melinda (Melinda Brooke)
    Abstract:
    L. C. Dunn (1893-1974) spent most of his scientific career conducting research in developmental genetics as a member of the Zoology Department at Columbia University in the City of New York. He had an accomplished scientific career researching mutations in mice, which earned him respect from other geneticists and scientists....

  • Seasonal movement patterns and habitat use of westslope cutthroat trout in two headwater tributary streams of the John Day River

    Creator:
    Starcevich, Steven J.
    Abstract:
    Radiotelemetry was used to study the seasonal movements and habitat use of adult westslope cutthroat trout Oncorhynchus clarki lewisi in Roberts Creek and Rail Creek, headwater tributaries of the John Day River, Oregon, from September 2000 to December 2001. The objectives were to (1) describe adult cutthroat trout life history...

  • Mormons and evolution : a history of B. H. Roberts and his attempt to reconcile science and religion

    Creator:
    Reid, Tim S.
    Abstract:
    Although much has been written describing the various reactions to the origin of Species in America, the Mormon reaction to Darwinism has been largely ignored. This dissertation will recount the history of this reaction as exemplified by the life and works of B. H. Roberts. Roberts's intellectual pursuits early in...

  • Seed dormancy in domesticated and wild sunflowers (Helianthus annuus L.) :types, longevity and QTL discovery

    Creator:
    Brunick, Robert L.
    Abstract:
    Elite inbred sunflower (Helianthus annuus L.) lines were found to have short-lived embryo and seed covering dormancies. Seed dormancy of wild sunflowers (H. annuus, H. argophyllus and H. exilis) was found to be controlled primarily by the seed covering (seed coat and pericarp) and embryo dormancy was short-lived (four to...

  • Supplemental feeding influences reproductive success of the Hawaiian goose (Branta sandvicensis) at Haleakala National Park, Maui, Hawai'i

    Creator:
    Tamayose, Joy
    Abstract:
    Low reproductive success has been typical of high elevation populations of the Hawaiian goose (Branta sandvicensis) or nēnē. Researchers identified predation and inadequate nutrition as limiting factors. Reproductive success remained low in most years despite on-going predator control programs. I used a supplemental feeding program over two breeding seasons in...
