Developing White Ash With Resistance To The Emerald Ash Borer, Kaitlin Joy Palla
Developing White Ash With Resistance To The Emerald Ash Borer, Kaitlin Joy Palla
Open Access Theses
Hypocotyls isolated from mature embryos germinated on Murashige and Skoog (MS) medium supplemented with 22.2 µM 6-benzyladenine (BA) and 0.5 µM thidiazuron (TDZ) were transformed using Agrobacterium tumefaciens strain EHA105 harboring the pBI121-8D2 vector containing the neomycin phosphotransferase (nptII) gene and a full length, codon-optimized Bacillus thuringiensis Cry8Da protoxin gene (cry8D2). Explants were transformed in a bacterial suspension with 100 µM acetosyringone using 90 s sonication and 10 min vacuum-infiltration. Four independent lines of transformed shoots were selectively regenerated on MS medium with 22.2 µM BA, 0.5 µM TDZ, 50 mg L-1 adenine sulfate, 10% …
Modulation Of Cell-Matrix Interaction For Cryopreservation Of Engineered Tissue, Angela Christine Seawright
Modulation Of Cell-Matrix Interaction For Cryopreservation Of Engineered Tissue, Angela Christine Seawright
Open Access Theses
Long term preservation of functional engineered tissues can significantly advance tissue engineering industry and regenerative medicine. Several preservation techniques have been proposed and investigated for this purpose, and cryopreservation is a leading candidate. While tissues are cryopreserved, ice forms in both the extracellular and intracellular spaces and causes freezing-induced spatiotemporal deformation of the tissue. During this process the cells undergo dehydration by the freezing-induced osmotic pressure difference and mechanical deformation, transmitted through cell-extracellular matrix adhesions. However, the significance and interaction of these cellular level transport and mechanics processes are not well understood. Therefore, this study aims to establish mechanistic understanding …
Interaction Between Centromeric Histone H3 Variant And Shugoshin, Visarut Buranasudja
Interaction Between Centromeric Histone H3 Variant And Shugoshin, Visarut Buranasudja
Open Access Theses
Precise and faithful segregation of chromosome segregation during mitosis depends on the ability of the cell to regulate chromosome bi-orientation on the mitotic spindle. Shugoshin (Sgo1), the protector of meiotic centromeric cohesin, is required for proper establishment of chromosome bi-orientation. Sgo1 plays a crucial role as part of a mitotic tension sensor between sister chromatids. Recently, Sgo1 has been reported to interact with histone H3 at the pericentromere region, as an important factor for tension sensing and chromosome segregation. However, the role of Sgo1 in tension sensing at centromere is still elusive. The centromere is the region of attachment of …
Omega-3 Fatty Acid Supplementation In The Management Of Chronic Lower Airway Inflammatory Conditions In Horses, Nora Nogradi
Omega-3 Fatty Acid Supplementation In The Management Of Chronic Lower Airway Inflammatory Conditions In Horses, Nora Nogradi
Open Access Theses
Chronic lower airway inflammatory diseases, such as recurrent airway obstruction (RAO) and inflammatory airway disease (IAD) are common in horses. RAO and IAD present many similarities with asthma in people. Based on studies in human asthma, omega - 3 polyunsaturated fatty acid (PUFA) supplementation has been proposed to improve clinical signs in horses with chronic lower airway inflammatory disease. The purpose of this study was to evaluate the clinical efficacy of an omega-3 PUFA containing equine feed supplement (AleiraTM) in horses with chronic lower airway disease. The study consisted of two separate experiments. First, a pilot study was …
Habitat Restoration Of A Constructed Ohio River Embayment, Caleb Michael Rennaker
Habitat Restoration Of A Constructed Ohio River Embayment, Caleb Michael Rennaker
Open Access Theses
Backwater habitats of large rivers provide habitat for aquatic biota and influence important predator-prey interactions in fishes and other aquatic organisms. However, these areas often exhibit turbid conditions and lack habitat complexity. Restoration of lentic habitats through direct habitat manipulations has shown success in prior efforts, but these methods have not been tested in backwater habitats of large rivers. I attempted to create habitat in an Ohio River embayment by establishing founder colonies of aquatic macrophytes coupled with the placement of underwater gravel beds. I also evaluated the effects of total suspended solids (TSS) on overwintering structures of American Pondweed …
