Timing of Volcanism in Central Oregon: Dating Tam McArthur Rim Volcano

Creator:: Landoni, Katherine G.
Abstract:: The Tam McArthur Rim is a volcanic center located within the Tumalo Volcanic Field (TVF), approximately 25 km west of Bend, OR. The rim comprises of shallowly dipping bedded sequences of intermediate and silicic flows with minor tephra interbedding capped by a rhyodacite dome. Glacial activity has exposed significant portions...

Inhibition of α-Amylase and α-Glucosidase by Bioflavonoids

Creator:: Griffith, Anneke M. (Tucker)
Abstract:: Various flavonoid-rich plant extracts have shown efficacy in the treatment of diabetes. Although it is often assumed that dietary flavonoids exert biological antioxidant effects, it is possible that the observed effects work in carbohydrate metabolism. In this study we evaluated the effect of catechins and catechin containing extracts on α-amylase...

Light quality manipulation for the solvent extraction of phycocyanin from Oregon freshwater cyanobacteria

Creator:: Gregor, Katelin
Abstract:: Phycocyanin, a photosynthetic pigment-protein complex produced by cyanobacteria, has critical value in the medical field at high purity. Costs associated with the extraction of this pigment are high, emphasizing the importance of optimal growth conditions. The aim of this study was to investigate potential commercial producers of phycocyanin by evaluating...

Impact of Vitamin E Deficiency on Hepatic Gene Expression of CRAL_TRIO Family Proteins in a Premier Vertebrate Animal Model

Creator:: Watt, Alexander T.
Abstract:: Vitamin E (vitE) is a group of lipid-soluble antioxidants- of which alpha-tocopherol is the most biologically active and only form considered to be an essential nutrient. Through preferential binding and trafficking, the alpha-tocopherol transfer protein (α-TTP) regulates the concentration of vitE in the body. The impact of vitE deficiency on...

Addressing ALS: Corroborating the Methodology of Studying the P2X7R Complex

Creator:: Veytsman, Edward Y.
Abstract:: Amyotrophic lateral sclerosis (ALS) is characterized by the degeneration of motor neurons in the motor cortex and spinal cord. Recent evidence suggests that the purine receptor P2X7 (P2X7R) plays a central role in the pathology of ALS. Previous research indicates that P2X7R activation by oxidatively modified heat shock protein 90...

Studies Toward the Synthesis of Natural Product Scaffolds

Creator:: Lusk, Jason S.
Abstract:: Part 1: A Diels-Alder Approach to the Synthesis of Novel Analogues of the Natural Product Siamenol Due to the prevalence of biaryl motifs in natural product synthesis, the Carter research group has been exploring the utility of a Diels-Alder approach to biaryl synthesis. The Diels-Alder approach involves a [4+2] cycloaddition...

The Effect of Riluzole on P2X7 and EAAT2 Expression by Inducible Neural Progenitor Cell (iNPC)-derived Astrocytes

Creator:: Sy, Kevin
Abstract:: Although it is the first drug approved for usage to treat amyotrophic lateral sclerosis (ALS), riluzole’s mechanism of action is unknown and its therapeutic quality is hampered by its relatively short window of effectiveness. P2X7 is a purine receptor found in astrocytes and other cells, which increases calcium concentrations within...

Improving the Photostability and Recovery of Organic Semiconductors

Creator:: Tollefsen, Ryan J.
Abstract:: This work aims to broaden use of the organic semiconductor pentacene (Pn) by means of improving its oxidation and photodimerization stability. In particular, we study the photophysical properties of functionalized Pn derivatives with side groups R in amorphous thin film, referred to as Pn-R-F8 when fluorinated. Using the optics experiments...

The Secret Life of Estuaries: Phytoplankton-determined Seasonality of Particulate Organic Carbon in Cathlamet Bay and the Columbia River Estuary

Creator:: Shumway, David O.
Abstract:: This study investigated the composition and character of organic matter on suspended particulate material (SPM) in the Columbia River estuary system to determine the contribution of biological activity in lateral bays to the greater nutrient cycle of the river. Water samples were collected during neap and spring tidal forcing (25...

Investigating synergistic effects of climate and land-use change on the pollination of a tropical plant, Heliconia tortuosa

Creator:: Dowd, Claire E.
Abstract:: Loss of biodiversity due to the effects of climate and land-use change may have implications for pollination services. Disruption to phenological synchronicity or a reduction in the overlap in species distributions of plants and their pollinators may reduce floral resources to pollinators, forcing them to move farther distances. If pollinators...
