  • The role of costimulation and adjuvants in the development of T cell effector and memory responses

    Creator:
    Maxwell, Joseph R.
    Abstract:
    T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...

  • Meiotic chromosome behavior in two tall fescue (Festuca arundinacea Schreb.) genotypes and their sterile hybrid

    Creator:
    Vásquez, Raul Moreno
    Abstract:
    Two diverse genotypes of tall fescue, Festuca arundinacea Schreb (6X=42), with normal fertility, produced upon intercrossing, vigorous F ₁ hybrid plants that were sterile. One parent genotype (P₁) was from P. I. 234-906, introduced from Switzerland and the other (P₉) was an introduction from Turkey, P. I. 174-209. P₁ and...

  • Uncovering the mechanism of IL-4-mediated T cell survival

    Creator:
    Moscibrocki, Cathleen M.
    Abstract:
    Although IL-4 is a well-characterized multi-functional cytokine, its role as a survival factor in T cells is not completely understood. In an attempt to uncover IL-4-mediated survival, we studied caspase activation in primary mouse T lymphocytes undergoing death by neglect, activation-induced or steroid-induced cell death. Here, we identify the executioner...

  • The influence of aryl hydrocarbon receptor activation on T cell fate

    Creator:
    Funatake, Castle J.
    Abstract:
    2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related compounds are well-recognized for their immunosuppressive activity, which is mediated through an intracellular receptor and transcription factor, aryl hydrocarbon receptor (AhR). Laboratory animals exposed to TCDD are less resistant to infection and have severely impaired humoral and cell-mediated immune responses. This dissertation addressed the hypothesis that...

  • Diversity combining ARQ over the m(> 2)-ary unidirectional channel

    Creator:
    Elarief, Noha
    Abstract:
    In diversity combining automatic repeat request (ARQ), erroneous packets are combined together forming a single, more reliable, packet. In this thesis, we give a diversity combining scheme for the m-ary unidirectional channel. A system using the given scheme with a t-unidirectional error detecting code is able to correct up to...

  • Investigations of regulatory T cell induction by 2, 3, 7, 8-Tetrachlorodibenzo-p-dioxin during a graft-versus-host response

    Creator:
    Marshall, Nikki B.
    Abstract:
    The immune toxicity of 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been studied for over 35 years, but only recently has the profound immune suppression associated with TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through binding the aryl hydrocarbon receptor (AhR), a ligand-activated transcription...

  • Possessed : embodiment, circulation, & subjectivity in Robinson Crusoe, Roderick Random, & Rob Roy

    Creator:
    Schneider, Rebecca
    Abstract:
    A majority of eighteenth-century novels remain in regular print over two hundred years since their inception. Yet with the possible exception of Robinson Crusoe, they have largely fallen out of popularity, rarely appearing on "The Summer's Hottest Reading" lists or receiving celebrity endorsement. I consider Ian Watt's foundational study, The...

  • Thinning effects on stand and tree growth : different perspectives on same old questions

    Creator:
    Romero Castaño, Pablo
    Abstract:
    The search for the stand density that optimizes growth and hence generates the maximum amount of wood is one of the philosopher’s stone in modern forestry. Since scientific methods were applied to forestry, numerous generations of foresters have studied the relations between stocking density and growth, obtaining diverse results and...

    Allen-Spencer, Patricia C.
    Abstract:
    Post World War II victory culture and its fallout-the consensus ideology-led to the creation of a middle class willing to conform to a prescribed set of ideals, safely removed from all danger, and enjoying the material benefits of a growing middle-class income bracket. Walt Disney and Hugh Hefner, two seemingly...

  • Enhancing pest mite biological control by Typhlodromus pyri (Acari: Phytoseiidae) in Pacific Northwest vineyards

    Creator:
    Gadino, Angela Noelle
    Abstract:
    The predatory mite Typhlodromus pyri (Acari: Phytoseiidae) is the predominant species in cool climate Pacific Northwest vineyards and a principal predator of pest mites including the grapevine rust mite Calepitrimerus vitis (Acari: Eriophyidae). In recent years vineyards have been experiencing C. vitis population outbreaks leading to increased economic damage from...
