Controlled Orientation of Engineered Carbonic Anhydrase on a Surface : A Model for Protein Immobilization for Biosensors and Biomaterials

Creator:: Brown, Wesley
Abstract:: Current protein immobilization techniques lack defined control over protein orientation. Protein orientation is important for making biosensors and biomaterials that are sensitive and efficient and can be crucial for designing some devices such as immunosensors or direct electron transferring biocells. A new method of protein immobilization is proposed that takes...

Insights into the Host Range, Population Decline, and Pathogenicity to Potato of Globodera ellingtonae

Creator:: Baker, Hannah V.
Abstract:: This thesis project has the following specific objectives: (i) Determine pathogenicity of Globodera ellingtonae to potato utilizing two trials conducted over a 16 week period, (ii) Elucidate the host range of G. ellingtonae using a variety of different Solanum weed species and crop species, and (iii) Characterize population decline of...

Effects of selenium supplementation during different trimesters of pregnancy on non-specific humoral immunity of pregnant beef cows and persistence of antibodies in their newborn calves

Creator:: Thompson-Hernandez, Ian
Abstract:: Immunosuppression during the periparturient period leads to increased susceptibility to infectious diseases in beef cows. Newborn calves rely on passive transfer of antibodies from their mothers at birth for protection against diseases in the first two months of age. It is unknown if supranutritional Se supplementation of cows during pregnancy...

De novo Discovery of Novel Long Noncoding RNAs in the North American Beaver

Creator:: Kashyap, Amita
Abstract:: Long noncoding RNAs (lncRNAs) are RNA molecules that are at least 200 nucleotides long and do not encode proteins. lncRNAs have roles in gene regulation, chromatin epigenetics, and molecular scaffolding. In light of mounting evidence implicating species-specific noncoding RNAs and gene regulatory mechanisms in species adaptations, it is reasonable to...

Biosynthetic Studies of the α-Amylase Inhibitor Trestatin in Streptomyces dimorphogenes

Creator:: Demessie, Ananiya A.
Abstract:: The prevalence of obesity and diabetes in the United States and globally has been rising in the last few decades and it continues to climb. One of the causes for this increase is the over consumption of sugars and/or carbohydrates. Among medications available to treat obesity and diabetes are the...

Effects of Contemporary Forest Practices on Stream Nutrients, Temperature, and Periphyton in Small Headwater Streams

Creator:: Pimont, Cedric
Abstract:: Forest harvest practices can impact nutrient concentrations and stream temperatures, altering aquatic ecosystems. To better inform future sustainable forest resource management practices, quantifying the impact of current practices on water quality, particularly in headwater streams is important. In this study, I quantified monthly nitrate-nitrite (N) and orthophosphate (P) concentrations, 7-day...

Native bees, honeybees and pollination in Oregon cranberries

Creator:: McKenney, Melissa A.
Abstract:: Farmers rely almost exclusively on the imported European honeybee (Apis mellifera L.) for fruit and vegetable crop pollination services. The recent decline in honeybee health has underscored he danger of relying on a single species to provide vital services. Increasing pollinator biodiversity with native bees may provide biological insurance against...

Opportunities and Limitations in Achieving Real-Time Observation of Soil Nitrate

Creator:: Auld, Ryan A.
Abstract:: There are many possible benefits that can arise from the ability to take real-time measurements of soil water nitrate concentrations in a field, from ecological to agricultural to industrial reasons. In order to achieve this, we adapted a NitraLED sensor with a ceramic porous cup in order to allow diffusion...

Ingestion of Microplastics in the Juvenile Black Rockfish (Sebastes melanops) from Oregon Coastal Sampling Sites

Creator:: Arnold, Madison A.
Abstract:: Microplastics (<5mm) are a ubiquitous environmental pollutant that have the potential to cause significant harm in many fish species. Therefore, understanding the quantities at which they are being consumed by living organisms is crucial for characterizing risk. There are currently gaps in the microplastic literature regarding microplastic data from finfish...

Exploring the Growth Habits of Sweetpotatoes (Ipomoea batatas) in the Willamette Valley of Western Oregon

Creator:: Epps, Charlotte
Abstract:: Sweetpotatoes are a highly nutritious staple crop, playing an important role in global nutritional security. Although the majority of research in the United States (U.S.) focuses on the cultivation of the storage roots, both the leaves and roots are edible. Sweetpotatoes are indigenous to the Andes Region of South America;...
