Ospc In The Pathogenesis Of Borrelia Burgdorferi, Sunita V. Seemanapalli
Ospc In The Pathogenesis Of Borrelia Burgdorferi, Sunita V. Seemanapalli
LSU Doctoral Dissertations
Lyme disease is a multisystem disorder caused by the tick vector Borrelia burgdorferi. During its life cycle between the tick vector and the mammalian host, Borrelia up- and down-regulates the expression of its surface lipoproteins. Of its many surface lipoproteins, the Outer surface protein C (OspC) is crucial for initial mammalian infection. OspC has a common role shared with other lipoproteins of protection against host innate defences and a unique function in facilitating the dissemination of B. burgdorferi in the murine host. The structure of OspC was solved in 2001 and the lipoprotein was found to be predominantly alpha-helical with …
Applicability And Integration Of Plasma Sprayed Hydroxyapatite Coated Ao Cortical Bone Screws In Equine Bone, Timm Gudehus
Applicability And Integration Of Plasma Sprayed Hydroxyapatite Coated Ao Cortical Bone Screws In Equine Bone, Timm Gudehus
LSU Master's Theses
To compare insertion temperatures and torques of Hydroxyapatite (HA) coated and uncoated 5.5 mm AO cortical screws in equine third metatarsal bones (MTIII) in vitro, and to compare insertion and extraction torques of HA coated and uncoated screws after 4, 8, 12 and 16 weeks of healing in equine third metacarpal bones (MCIII) in vivo. No significant temperature differences were recorded in cadaveric bones for AO and HA coated screws. Insertion torques were significantly higher for HA coated implants compared to uncoated screws. In vivo, the AO screws lost 50% of their initial stability within 4 weeks of healing and …
In Vivo And In Vitro Pathogenesis Of Francisella Asiatica In Tilapia Nilotica (Oreochromis Niloticus), Esteban Soto
In Vivo And In Vitro Pathogenesis Of Francisella Asiatica In Tilapia Nilotica (Oreochromis Niloticus), Esteban Soto
LSU Doctoral Dissertations
Francisella asiatica is a Gram negative, facultative intracellular pathogen that causes fish francisellosis. In this project, homologues to the F. tularensis iglABCD genes were found present in F. asiatica. As few as 23 F. asiatica bacteria injected in the peritoneum were found capable of causing mortalities in tilapia nilotica (Oreochromis niloticus), and even fewer were enough to cause pathological changes. We examined the in vivo and in vitro interaction of F. asiatica wild type (WT) and a ÄiglC strain with tilapia and tilapia head kidney derived macrophages (HKDM). The ÄiglC was found to be attenuated following intraperitoneal and immersion challenges …
Role Of Gastrointestinal Multidrug Resistance (Mdr1) Gene And P-Glycoprotein (P-Gp) In The Oral Absorption Of Methadone In Horses, Renata Lehn Linardi
Role Of Gastrointestinal Multidrug Resistance (Mdr1) Gene And P-Glycoprotein (P-Gp) In The Oral Absorption Of Methadone In Horses, Renata Lehn Linardi
LSU Doctoral Dissertations
Methadone is a mu-opioid receptor agonist which is a very effective analgesic used to treat moderate to severe acute and chronic pain in humans. Due to methadone’s minimal undesirable side-effects in people, we believed it could be of use in horses as an analgesic agent. As found with the majority of lipophilic drugs, absorption of methadone occurs primarily in the small intestine via transcellular transport and its absorption is regulated by P-glycoprotein. P-glycoprotein is a transmembrane transporter protein encoded by the multidrug resistance gene, which is constitutively expressed in the apical membrane of enterocytes of various species. This protein may …
The Role Of Bone Marrow In Siv Pathogenesis Using The Rhesus Macaque Model, Amy F. Gill
The Role Of Bone Marrow In Siv Pathogenesis Using The Rhesus Macaque Model, Amy F. Gill
LSU Doctoral Dissertations
CD4+ memory T cells are depleted in mucosal tissues post human immunodeficiency virus (HIV) and simian immunodeficiency virus (SIV) infection without restoration to pre-infection levels during progressive course of disease. Bone marrow (BM) as a hematopoietic organ has been investigated for hematologic and morphologic changes during HIV infection. However, BM as a primary lymphoid tissue during HIV infection has been poorly characterized. We proposed BM was also a site of CD4+ T cell depletion driven by increased apoptosis during progressive HIV disease. We chose to investigate bone marrow changes using the premier non-human primate Rhesus macaque SIV model for the …
In Vitro And In Vivo Evaluation Of A Brucella Putative Hemagglutinin, Lauren E. Duhon
In Vitro And In Vivo Evaluation Of A Brucella Putative Hemagglutinin, Lauren E. Duhon
LSU Doctoral Dissertations
Brucellosis, a zoonotic disease caused by Brucella spp., presents both health and economic difficulties for livestock, wildlife, and humans. While brucellosis is nearly eradicated in the United States, the disease remains detrimental in many countries worldwide. Attempts to produce a safe and effective small ruminant vaccine have been met with limited success. The current vaccine for bovine brucellosis in the United States is B. abortus RB51. This strain transiently colonizes the host and induces a cell-mediated immune response. Levels of protection have not been demonstrated in goats and thus it is considered a relatively poor caprine vaccine that probably does …
Carprofen-Induced Oxidative Stress In Mitochondria Of The Colonic Mucosa Of The Dog, Lynne A. Snow
Carprofen-Induced Oxidative Stress In Mitochondria Of The Colonic Mucosa Of The Dog, Lynne A. Snow
LSU Master's Theses
Objectives 1) To measure conductance and permeability of canine colonic mucosa exposed to increasing concentrations of carprofen. 2) To compare conductance and permeability of canine colonic mucosa exposed to carprofen or 2,4-dinitrophenol (DNP) and tempol blockade. Design In vitro randomized block design Animal 20 mixed breed dogs Methods Conductance, mannitol flux, and histology were evaluated in colonic mucosa mounted in Ussing chambers. Mucosa was first exposed to increasing concentrations of carprofen. Mucosa was then exposed to either carprofen (200 μg/ml) or DNP (0.25mM) +/- tempol (1mM) pretreatment. Conductance over time, mannitol fluxes, and frequency of histologic categories were analyzed for …
