  • Alteration of cholesterol disposition by chlordecone is not explained by induction of cyp7a or cyp4a1

    Creator:
    Lee, JungA
    Abstract:
    Liver X receptor (LXR), farnesoid X receptor (FXR) and peroxisome proliferator-activated receptor (PPAR) are adopted orphan nuclear receptors that function as lipid sensors. These receptors respond to cellular lipid levels and regulate the expression of target gene. Previously, it was demonstrated that low doses of chlordecone (CD) pretreatment disturbed exogenous...

  • The determination of alkaline phosphatase activity and analysis with a portable clinical analyzer of serum and peritoneal fluid from horses suffering colic

    Creator:
    Saulez, Montague N.
    Abstract:
    Alkaline phosphatase (ALP) is an enzyme present in intestinal mucosa, bile, bone and renal tubule cells. Bile acids have been shown to decrease ALP activity from bone and kidney but not those from intestinal origin. This action can be mimicked in serum and peritoneal fluid samples by the use of...

  • The physiology and anatomy of the esophagus of normal llamas and llamas with megaesophagus

    Creator:
    Sukon, Peerapol
    Abstract:
    Solid-state esophageal manometry was used to study physiology of the normal llama esophagus. Esophageal baseline pressures, esophageal response to water swallows and to balloon distention, and other motor activity of the esophagus during experiments were measured throughout the entire length of the esophagus. Gross and histologic anatomy, muscle fiber type...

  • Biosynthetic studies of fungal diterpene antibiotics

    Creator:
    Yao, Qingmei
    Abstract:
    The isoprenoid pathway is one of the major biosynthetic pathways of secondary metabolites. Isoprenoids with a C₂₀ skeleton are known as diterpenoids and are derived from the common precursor, geranylgeranyl diphosphate (GGPP). This dissertation describes approaches to discover the diterpene synthase enzymes which provide the backbone structures for pleuromutilin and...

  • Wavelet analysis : linking multi-scalar pattern detection to ecological monitoring

    Creator:
    Anthony, Jill Ada Marie
    Abstract:
    Wavelet analysis is an analytical and modeling tool for optimizing sampling efficiency and accuracy, particularly in the context of designing long-term, large-scale monitoring plans. As a pattern analysis method that accommodates and preserves non-stationarity, wavelet analysis provides novel visualization and analytical capabilities for increased insight into interactions between multi-scalar heterogeneous...

  • Analysis of the effect of the potassium ion on fowl sperm motility

    Creator:
    Gamble, Kari
    Abstract:
    Fowl sperm are believed to be immotile prior to ejaculation. The concentration of potassium found in deferent duct fluid is approximately 8 times higher than that found in blood plasma, which is 5 mM in Gallus domesticus. The effect of ionic potassium on fowl sperm motion was tested in a...

  • Hemoglobin adducts of the organophosphate insecticide azinphos-methyl

    Creator:
    Bailey, Bonnie J.
    Abstract:
    Reported here is an investigation to determine if azinphos-methyl (AZM), an organophosphate insecticide, adducts to hemoglobin, and if so, whether the hemoglobin adduct could be used as a quantitative marker of occupational AZM exposure. We hypothesized that AZM, or a metabolite of AZM, binds to hemoglobin in erythrocytes forming an...

  • Involvement of inflammation and associated Mac-1⁺Gr-1⁺ cells in the immune suppression induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)

    Creator:
    Choi, Jin-Young, 1964
    Abstract:
    Exposure to TCDD suppresses the generation of immune responses through unknown mechanisms. Interestingly, TCDD enhances inflammatory responses to various stimuli. The goal of the studies presented in this thesis was to examine the role of hyperinflammation in TCDD-induced immunotoxicity. Previously we observed an increase in Mac-1⁺ cells in the spleen...

  • Non-specific innate immunity against Escherichia coli infection in white leghorn chickens

    Creator:
    Huang, Hsuan-Jen
    Abstract:
    This research was initiated to investigate a high mortality problem occurring in market age broiler chickens in Oregon. Initial field investigations revealed that mortality was due to the systemic bacterial infections. The subsequent laboratory experiments suggested that suppressed short-term, non-specific innate immunity rather than pathogenic properties of bacteria caused the...

  • Genetic variation of chlamydial Inc proteins

    Creator:
    Viratyosin, Wasna
    Abstract:
    Genomic analysis is a new approach for the characterization and investigation of novel genes, gene clusters, the function of uncharacterized proteins, and genetic diversity in microorganisms. These approaches are important for the study of chlamydiae, a system in which several genomes have been sequenced but in which techniques for genetic...
