Efficient Separation And Sensitive Detection Of Listeria Monocytogenes Using Magnetic Nanoparticles, Microfluidics And Interdigitated Microelectrode Based Impedance Immunosensor, Damira Ashimkhanovna Kanayeva

Graduate Theses and Dissertations

Listeria monocytogenes continues to be a major foodborne pathogen that causes food poisoning and sometimes death in immunosuppressed people and abortion in pregnant women. Nanoparticles have recently drawn attentions for use in immunomagnetic separation techniques due to their greater surface area/volume ratio and better stability against sedimentation in the absence of a magnetic field. Interdigitated microelectrodes and microfluidics make material transfer more efficient and biological/chemical interaction between the surface and solution phase much quicker. Magnetic nanoparticles (Fe3O4) with a 30 nm diameter were functionalized with rabbit anti-L. monocytogenes antibodies via biotin-streptavidin bonds and then amalgamated with target bacterial cells …

Violence, Symbols, And The Archaeological Record: A Case Study Of Cahokia's Mound 72, Kathryn Koziol

Graduate Theses and Dissertations

Acts of violence are not always easily distinguished in their form. Given the additional difficulties caused by the obscure nature of the archaeological record, it is no wonder that interpretations of these behaviors are so skewed both between and within fields of research. There is little consistency in this academic dialogue, which prevents researchers from grappling with the larger perspectives that should be approached. For instance, just how far back in our human history have events such as genocide occurred? Are these modern in origin? The scale of ancient events and our anthropological scopes need more adjustment to the unique …

Recommendations For The Chamlidere Petrified Forest Management Plan, Fatma Ertem

Graduate Theses and Dissertations

Anything inherited from our ancestors or from nature can be considered as our heritage. Heritage can be classified as cultural and natural heritage. Turkey has been the cradle of many civilizations, religions, and ethnic groups because of the unprecedented natural heritage and critical geopolitical location of Anatolia. Given all the treasure of cultural and natural heritage in Turkey, heritage management practices have not been emphasized as they deserve. A petrified forest was found in Chamlidere, Ankara (Turkey) in 2004. Chamlidere petrified forest preserves information related to the biodiversity of forests in the Galatian Volcanic Province during the Early-Middle Miocene. When …

An Evaluation Study: Does The Workforce Investment Act Impact Secondary Student Retention In Selected Mississippi Delta Communities?, Tyrone Price Dooley

Graduate Theses and Dissertations

This study used a quasi-experimental cross-sectional quantitative model to evaluate the Youth Development Program, a component of the federal Workforce Investment Program. This evaluation study determines whether participation in the Youth Development Program reduced dropout rates among youth in secondary schools in seven school districts in the southeast Arkansas Delta. The impact of the Youth Development Program was examined in the following school districts: Dollarway, Pine Bluff, Watson Chapel, White Hall, Stuttgart, Dewitt, and Star City. The cross-sectional analysis covered the 2006 through 2008 program years. The evaluation model consisted of a comparison group that included 437 youth randomly drawn …

Characterization Of Neuronal Groups Regulating Sexual And Agonistic Behavior In Male Chicken (Gallus Gallus), Jingjing Xie

Graduate Theses and Dissertations

The study aimed to understand the neuronal regulation of male sexual and agonistic behavior in broiler breeders. First, brain structures associated with sexual and agonistic behavior were identified by mapping Fos expression. The ventromedial subnucleus of medial portion of bed nucleus of the stria teriminalis (BSTM2) was specifically activated by male courtship behavior. The medial preoptic nucleus (POM) and lateral septum (SL) were associated with both sexual and agonistic behaviors. The bed nucleus of the pallial commissure (NCPa) and the paraventricular nucleus (PVN) were closely related to stress. Second, Fos-ir neurons were phenotyped by double labeling Fos with aromatase (ARO) …

Applications Of Site-Specific Recombination Systems In Transgene Expression And Marker Gene Removal, Mehmet Aydin Akbudak

Graduate Theses and Dissertations

Site Specific Recombination systems, such as FLP-FRT and Cre-lox, have been successfully used for site-specific gene integration and marker-gene deletion in plant systems. They are very useful tools in the integration of single-copy full-length transgene cassettes into the genome because the transgene integration via conventional methods often generate multi-copy locus. Such complex locus containing direct and inverted repeats of full-length and truncated copies of the transgene cassette generate aberrant RNA resulting in gene silencing. Therefore, for stable gene expression, a single copy transgene locus is preferred. However, even single copy locus sometimes succumbs to gene silencing. Although the mechanism is …

Intraspecific Variation In Two Cosmopolitan Myxomycetes, Didymium Squamulosum And Didymium Difforme (Physarales: Didymiaceae), Katherine Elizabeth Winsett

Graduate Theses and Dissertations

The myxomycetes (plasmodial slime molds or myxogastrids) are one of three groups considered to be true slime molds (class Eumycetozoa sensu Olive 1975). Two vegetative states--amoebae and plasmodia--along with a spore-producing fruiting body characterize the life cycle of the myxomycetes. These organisms are associated with decaying plant material and are found in all terrestrial habitats worldwide. A number of species are considered cosmopolitan, being found worldwide, where they are associated with a diversity of microhabitats and substrates. A review of the literature, including molecular investigations in all three groups of slime molds, is presented, and this is followed by four …

Pharmacokinetic Evaluation Of The Blood: Tissue Relationship In Poultry: Screening For Antibiotic Residues In Chicken Muscle, Ixchel Reyes Herrera

Graduate Theses and Dissertations

During their life, humans are exposed to numerous substances that are naturally present in the environment or that are the result of man made processes, including heavy metals, persistent organic pollutants, pesticides and veterinary drugs. Some of these substances can leave residues in food products and possibly expose consumers to their potential toxic effects. To address these problems extensive regulatory efforts are devoted to prevent, detect and control these substances from reaching the food supply. However, given the vast diversity of food products that requires monitoring and the immense diversity of potential chemical contaminants, the need for an efficient and …

Analysis Of The Response Of Medicago Truncatula Calcium Oxalate Mutants To Abiotic Stress, Wayra Gabriela Navia-Gine

Graduate Theses and Dissertations

Calcium oxalate crystals are found in most plant species. In Medicago truncatula wild-type A17, crystals accumulate in leaves along the secondary veins and the only role attributed to them so far is defense against chewing insects. Calcium oxalate deficient (cod) mutants were isolated in M. truncatula; the cod mutants include cod5, which completely lack crystals in the leaves and cod6 that accumulates fewer and smaller crystals compared to A17. We analyzed gene expression in the cod mutants and A17 using GeneChip® Medicago Genome Arrays and found important differences in transcriptome between the three genotypes. In particular, we found a gene …

Tryptophan Anchored Peptides In Lipid Bilayer Membranes: Control Of Peptide Orientation And The Phase Behavior Of Cholesterol-Containing Ternary Lipid Mixtures, Johanna Maria Rankenberg

Graduate Theses and Dissertations

Model WALP peptides and "next generation" WALP-derived hydrophobic model peptides were employed to discover principles that govern protein-lipid interactions in biological membranes.

Ternary cholesterol-containing lipid mixtures were examined in the presence of WALP peptides of different lengths (acetyl-GWW(LA)_nLWWA-ethanolamide, with n between 3 and 8). Deuterium NMR spectra from labeled lipids reveal that WALP peptides may stabilize lipid ordered "raft" domains and therefore promote lipid phase separation, albeit to a minor extent. The results depend upon whether dioleolyl- or diphytanoyl-phosphatidylcholine is present as the fluid lipid component.

Several WALP peptides were modified to remove anchoring Trp residues from one …
