Evaluation Of Plasma Sprayed Hydroxyapatite Coated Ao Cortical Screws In Equine Third Metacarpal Bone, Myra Elizabeth Durham
Evaluation Of Plasma Sprayed Hydroxyapatite Coated Ao Cortical Screws In Equine Third Metacarpal Bone, Myra Elizabeth Durham
LSU Master's Theses
ABSTRACT Objectives - To compare the osteointegration of plasma sprayed hydroxyapatite (HA) coated and uncoated 5.5 mm cortical screws in equine third metacarpal (MC3) bones in combination with a 4.5mm broad dynamic compression plate (DCP). Study design - In vivo study. Animals – 6 Adult Thoroughbred horses. Methods – For each horse, four HA coated screws were placed unicortically through a 4.5mm broad DCP in the dorsal cortex of a randomly chosen MC3 bone, with 4 uncoated screws placed in an identical manner in the contralateral MC3 bone. All screws were tightened to a torque of 5.4 N-m. Extraction torques …
Role Of Intraocular Leptospira Infections In The Pathogenesis Of Equine Recurrent Uveitis In The Southern United States, Florence Polle
Role Of Intraocular Leptospira Infections In The Pathogenesis Of Equine Recurrent Uveitis In The Southern United States, Florence Polle
LSU Master's Theses
To investigate the role of intraocular leptospiral infections in horses with Equine Recurrent Uveitis (ERU), ocular fluid samples were collected from donated and client-owned horses with a history and ocular findings consistent with chronic ERU. Additionally, eyes were harvested from horses with normal ophthalmic examinations as a control group. Blood samples were obtained for Leptospira serology using microscopic agglutination test (MAT). Aqueous and vitreous humor samples were aseptically obtained and submitted for aerobic culture and Leptospira culture, PCR and MAT. Twenty-one control horses (40 eyes) and 31 ERU horses (46 eyes) were available for study. Serology results were available for …
The Effects Of Iodixanol Present During Equine Semen Cryopreservation, David Paul Beehan
The Effects Of Iodixanol Present During Equine Semen Cryopreservation, David Paul Beehan
LSU Master's Theses
The objectives of this study were to determine what effects iodixanol would have on total and progressive motility, plasma membrane integrity (viability), acrosome integrity and DNA structure when present during cryopreservation of equine spermatozoa,. We hypothesized that the addition of iodixanol would improve post-thaw values for measured parameters. Ejaculates from six stallions were collected, centrifuged at 900 x g for ten minutes to remove supernatant, and suspended to 200 x 106 cells/ml with 0%, 2.5% and 5% iodixanol in an egg-yolk based extender and cryopreserved. Before and after cryopreservation sperm motility was assessed by computer assisted semen analysis, and samples …
Structural And Molecular Pathology Of The Atrium In Boxer Arrhythmogenic Cardiomyopathy, Jorge Luis Vila
Structural And Molecular Pathology Of The Atrium In Boxer Arrhythmogenic Cardiomyopathy, Jorge Luis Vila
LSU Master's Theses
Arrhythmogenic cardiomyopathy (AC), also known as arrhythmogenic right ventricular cardiomyopathy (ARVC), is a disease characterized by fatty or fibro-fatty myocardial replacement, predominantly in the right ventricle and to a lower extent the left ventricle. It is recognized as a disease affecting the cardiac intercalated disc. Clinically, it is associated with ventricular arrhythmias, although atrial arrhythmias and atrial histopathological changes characteristic of AC have occasionally been reported. The full extent of atrial involvement in AC has not been investigated. Therefore, we aimed to apply histopathology, immunochemical detection, immunolocalization and transmission electron microscopy (TEM) techniques to characterize the distribution of desmosomal and …
Immunization Of West Nile Recombinant Envelope Domain Iii With Equine Cd40 Ligand Protein Vaccine Induced Specific Immune Response In Rabbits And Horses, Shiliang Anthony Liu
Immunization Of West Nile Recombinant Envelope Domain Iii With Equine Cd40 Ligand Protein Vaccine Induced Specific Immune Response In Rabbits And Horses, Shiliang Anthony Liu
LSU Master's Theses
West Nile virus (WNV) is one of several flaviruses known to infect mammalian species, including humans. There were 15,257 horse cases reported in 2002 and 1,086 in 2006 in United States. Recently, significant increases in equine and human cases have been reported in United States. Domain III of the WNV envelope protein binds to cellular receptors, and induces a significant portion of the neutralizing antibody response against the virus. CD40 Ligand (CD40L, CD154) enhances productive interactions between T cells and APC and has been shown to function as a potential adjuvant. In this study, we constructed and expressed a fusion …
Isolation And Characterization Of Adult Progenitor Cells From Healthy And Laminitic Hoof Tissue, Vanessa Pinto
Isolation And Characterization Of Adult Progenitor Cells From Healthy And Laminitic Hoof Tissue, Vanessa Pinto
LSU Master's Theses
Laminitis is an often fatal condition in horses with few available and only moderately effective treatment options. Separation of laminar dermis and epidermis lead to rotation or ventral deviation of the third phalanx inside the hoof capsule. Despite being a modified skin, equine laminar tissue does not completely return to normal after laminitis. The hypothesis tested was that adult progenitor cells in the equine laminar tissue are irreversibly damaged by laminitis. A method to harvest and culture cells in vitro from the equine lamina was established; and progenitor cells from unaffected and laminitic hooves were characterized and compared. Laminar tissue …
