  • Antibiotic Resistance Gene Transfer in Oysters as a Result of Fecal Pollution

    Creator:
    Cooper, Rebecca
    Abstract:
    Antibiotic resistance is an increasing problem in many species of bacteria today, with pathogens an important focus. Fecal contamination of shellfish is already a concern due to potential pathogens. This report examines the possibility of resistance gene transfer between microbes, due to fecal bacteria, within the oyster. In this study,...

  • Telomere Binding Protein Antagonists for Stem Cell Therapy

    Creator:
    VanGarde, Aurora
    Abstract:
    Understanding the mechanisms through which stem cells self-renew is important for the development of new therapies to repair and restore damaged tissue. This research explores possible mechanisms of telomere mimic action and seeks to validate a new assay for evaluating telomere binding antagonists and studying the effects of telomere binding...

  • An Evaluation of Staffing Needs at the Health Clinic in Maunatlala, Botswana

    Creator:
    Bedge, Sonya S.
    Abstract:
    As part of the Botswana Global Learning Internship Program, a qualitative study was conducted regarding the current staffing conditions at the local village health clinic in Maunatlala, Botswana. This was a month-long project conducted over the summer of 2018. Students from Oregon State University lived in the village of Maunatlala...

  • Progestin analysis by gas chromatography/mass spectrometry in plasma and feces of horses, cattle, and sheep

    Creator:
    Miller, C. W.
    Abstract:
    Much interest has recently been shown in using fecal samples to monitor hormone concentrations in free-roaming animal populations. This process is noninvasive and, therefore, provides easy sample collection and assures no stress-related, physiological responses that might alter the hormonal data. Concerns have been expressed, however, that the hormone concentrations detected...

  • Phytochemical characterization of Fagonia indica and its effects on MCF-7 breast cancer cell line

    Creator:
    Kumbi, Yadano
    Abstract:
    Phytochemicals from the genus, Fagonia, have been attracting increasing attention due to their potential beneficial effects on human health, particularly, anti-cancer properties. Certain Fagonia species contain various types of phytochemicals such as saponins, alkaloids, cardiac glycosides, flavonoids, terpenoids, and tannins. In this study, we investigated the phytochemical composition of a...

  • Enhancing Protocols to Improve Consistency Across Nanotoxicology Studies

    Creator:
    Luker, Sabrina R.
    Abstract:
    In current nanotoxicology research, there is a lack of standardization in reporting of zebrafish exposure media and sonication practices. This lack of standardization in use and reporting methods has made reproducing nanoparticle (NP) toxicity results between labs a common issue. It is important to have a standardized way of reporting...

  • A Comparative Analysis of Mercury and Lead in Sindoor from the U.S. and Bangladesh

    Creator:
    Breen, Anna K.
    Abstract:
    Heavy metals have historically been popular for use in cosmetics manufacturing due to the colorful pigmentation of heavy metal compounds. In the case of sindoor, a cosmetic used by married Hindu women for religious purposes, mercury sulfide, lead tetroxide, and lead chromate are compounds suspected to still be involved in...

  • The toxicogenetic effects of a chitosan based hemostatic control patch in rat models

    Creator:
    Colburn, Andrew J.
    Abstract:
    Chitosan based hemorrhage control dressings provide effective external hemorrhage control while having few side effects. Known residual contaminants present in chitosan formulations include endotoxins and proteins known to stimulate gene expression in the liver. This study investigated gene expression in the liver using rat bio-compatibility models to gain knowledge regarding...
