Vernalization gene architecture as a predictor of growth habit in barley

Creator:: Heckart, Douglas
Abstract:: Winter hardiness in barley (Hordeum vulgare) is a trait targeted by breeding programs in order to expand the potential area of adaptation of fall-sown cereals. Vernalization requirement is an important factor in winter hardiness. A vernalization requirement is an extended period of low temperature required for transition from the vegetative...

Characterization of a Sporulation-Specific Kinase in Clostridium perfringens

Creator:: Danielson, Bryan
Abstract:: Clostridium perfringens type A isolates produce the spore-specific enterotoxin, CPE, upon sporulation in the gastrointestinal tract of humans and animals. Spo0A is a response regulator representing the major transcription factor for sporulation initiation in C. perfringens. In Bacillus subtilis, a multicomponent phosphorelay involving five histidine kinases (KinA-KinE), the intermediate response...

Degradation of Extracellular Matrix Proteins by Bovine Embryonic Urokinase-Type Plasminogen Activator

Creator:: Hansen, Lance
Abstract:: The bovine blastocyst is composed of a one-celled layer of trophectoderm surrounding a fluid filled sac called the blastocoel and a ball of cells called the inner cell mass (ICM). On Day 8 (Day 0=fertilization) in bovine embryos, endodermal cells leave the ICM, migrate over the extracellular matrix (ECM) on...

Use of sheep in the control of an invasive bunchgrass

Creator:: Scholz, Ryan
Abstract:: Studies were conducted to assess influencing the effectiveness of sheep for grazing control of false brome (Brachypodium sylvaticum) an invasive grass species. Orphan lambs were exposed to false brome via grass extract in their milk and naturally reared lambs were exposed by grazing dense stands of false brome with their...

Method development in in vitro immune response

Creator:: Huber, Jacob
Abstract:: The AhR is a ligand-activated transcription factor that mediates the potent immunosuppressive effects of TCDD. AhR-dependent changes in gene expression appear to alter the differentiation of CD4+ T cells to induce a population of CD4+CD25+ T regulatory cells (Tregs) that suppress the immune response. Ascertaining if and how the AhR...

Expression of prolactin in feline mammary adenomas and adenocarcinomas

Creator:: Trummel, Danielle K.
Abstract:: Mammary tumors are the third most common tumor in cats after cutaneous neoplasia and lymphosarcoma. More than 80% of feline mammary tumors are adenocarcinomas, which are similar to human mammary adenocarcinomas in their biologic behavior and histologic characteristics. Despite treatment with radical mastectomy, feline mammary adenocarcinoma is associated with a...

Developing the Zebrafish (Danio rerio) As a Model to Evaluate the Toxicity of Chlorinated and Non-Chlorinated Solvents

Creator:: Wenning, Matthew
Abstract:: Chlorinated and non-chlorinated solvents are used in a variety of industrial processes and as a consequence, they have become environmental contaminants as well. Because of this, they lead to both occupational and environmental exposures. Exposure to these compounds can potentially result in various forms of neurological damage with a wide...

Genetic variation of Renibacterium salmoninarum genes in infected salmonids

Creator:: Burnett, Jeffrey R.
Abstract:: Renibacterium salmoninarum is the causative agent of bacterial kidney disease in both wild and farmed salmonid species worldwide. The genome of this pathogen has significant synteny to the ubiquitous, soil-dwelling Arthrobacter spp. though it is 1.9 Mb smaller, suggesting that reductive evolution has occurred. Recently, our group finished sequencing and...

The toxicogenetic effects of a chitosan based hemostatic control patch in rat models

Creator:: Colburn, Andrew J.
Abstract:: Chitosan based hemorrhage control dressings provide effective external hemorrhage control while having few side effects. Known residual contaminants present in chitosan formulations include endotoxins and proteins known to stimulate gene expression in the liver. This study investigated gene expression in the liver using rat bio-compatibility models to gain knowledge regarding...

Effects of land management on carbon and nitrogen in soils from New Zealand

Creator:: Holcomb, Jess
Abstract:: The ability of soils to store large quantities of carbon (C) makes them an important factor in the global C cycle. Small changes within soil C can lead to large changes in atmospheric C. Land management practices can influence the amount of C that is stored within the soil and...
