“SeW: A Search for Selenosulfide Bonding” and “Severity of Damage Inflicted on Intercellular Disulfide Bonds as a Result of UV Radiation”

Creator:: Dutcher, Kendall
Abstract:: Part 1: White muscle disease (WMD), a degenerative muscle disease brought on by a deficiency of the essential trace nutrient selenium, is thought to be mediated by the protein Selenoprotein W (SeW). In its relationship with WMD, SeW, like many selenoproteins, binds to glutathione, serving some purpose in redox mechanisms...

A Comparison of Ammonia Inhibition on the Anaerobic Digestion of Organic Acids Between Digestate from Anaerobic Co- and Mono-Digestion Systems

Creator:: Ruiz-Orozco, Gloria
Abstract:: Anaerobic digestion is a common terminal step in wastewater treatment systems and produces valuable by-products such as biogas, a combination of carbon dioxide and methane. Biogas can be used to off-set energy costs, and along with the anaerobic co-digestion of fats, oils, and greases (FOG) has been found to increase...

A Metabolomics Driven Investigation of Polyamine Metabolism During Adipogenesis

Creator:: Hughes, Taylor Neil
Abstract:: Obesity is achieved at the point where fat accumulation begins to exert deleterious effects on an organism. The human body accrues fat when there is an energy imbalance occurring, where caloric intake exceeds expenditure.Many anti-obesity drugs used in the past have had undesirable side effects, and currently there is a...

A Needs Assessment of Precollege STEM Education at OSU and Social Emotional Learning (SEL) Integration

Creator:: Rodriguez Cardoso, Metzin A.
Abstract:: STEM education is delivered to K12 audiences by Pre-college Programs across the nation, many of which serve underrepresented and underserved students as part of their core missions. While there is robust attention to STEM curriculum development and college connection events in such programs, few have social-cultural aspects of learning as...

A Novel Statistical Method for Identifying Monotonic Relationships in Noisy Plots

Creator:: Eberhart-Garah, Robbie
Abstract:: As scientific technologies and techniques have improved in past decades, it has become possible to quickly collect unprecedented quantities of experimental data. In the study of gene expression, for instance, datasets comprising tens of thousands of variables and hundreds of treatments can be produced in a matter of months. When...

A Panel of Histone H3 Mutations to Investigate Centromere Maintenance and Gene Silencing

Creator:: Esposito, Madison L.
Abstract:: Modifications of histone tail amino acid residues are necessary for many reactions involving chromatin. These processes can produce transcriptionally active, euchromatic, or inactive, heterochromatic, segments of DNA. The formation and maintenance of facultative heterochromatin is critical for the proper growth and development of many eukaryotes. Euchromatin can be changed into...

A Performance Evaluation of In-Stream Hatchboxes and Streamside Incubators for Chinook Salmon

Creator:: Howell, Meghan Z.
Abstract:: Hatcheries are used to produce salmon to augment the number of fish available for harvest, and to supplement wild populations that may be threatened with extinction. Although traditional hatchery rearing methods can produce many fish, they can pose risk to wild populations because they tend to produce salmon with lower...

A phenological examination of terrestrial invertebrate abundance at H. J. Andrews Experimental Forest, Oregon

Creator:: Mackereth, Kailan F.
Abstract:: Abstract Understanding the effects of climate change on forest ecosystems requires exploration of the relationships of different components of the system, such as the response of biota to local hydrology, temperature, precipitation, and elevation. The Long-term Ecological Research Program at the H. J. Andrews Experimental Forest, located in the Western...

A Pro-Inflammatory Agent, Lipopolysaccharide, Can Mimic the Effects of Aging on Spatial Reference Memory

Creator:: Escobedo, Emily R.
Abstract:: Humans and rodents experience declines in reference (long-term) and working (short-term) memory and cognitive flexibility during the aging process. Aging changes in GluN1 and GluN2B subunits of N-methyl-D-aspartate (NMDA) receptors show a relationship to both reference and working memory deficits. Sulindac, an anti-inflammatory drug, enhances working memory and NMDA receptor...

A reassessment of the linkage of red leaf trait and incompatibility loci in hazelnut (Corylus avellana L.)

Creator:: Horton, G.
Abstract:: As in other species, it is possible that a homozygous red leafed (= redleaf) hazelnut (Corylus avellana L.) tree would have brighter red coloration than a heterozygote and thus be more desirable as an ornamental. However, 'Fusco Rubra' and `Rode Zeller' both carry incompatibility allele S6 (thus cross-incompatible) and are...

A screening method for the essential oils in hops using solid-phase microextraction

Creator:: Heider, Chris
Abstract:: Separation and isolation of organic analytes from environmental matrices such as soils, water, plant, or animal tissue has traditionally involved the use of liquid solvent extractions. Solvent-based extraction methods are often time-consuming, difficult to automate, and use expensive solvents that generate hazardous waste and working conditions. The need for a...

A survey of three key species of ambrosia beetles (Coleoptera: Curculionidae: Scolytinae: Monarthrum scutellare, Xyleborus dispar, Xyleborinus saxesenii) in Oregon's Willamette Valley nursery industry

Creator:: Cramer, Eryn E.
Abstract:: The nursery industry plays a critical role in Oregon's economy. An increase in wood-boring insect, or borer, activity has impacted the industry. The goal of this research is to determine key borer species in the nursery industry, flight times so targeted spray schedules can be established, and assess grower knowledge...

Age-related response of isolated rat hepatocytes to menadione and (R)-[alpha]-lipoic acid

Creator:: Graves, Jason T.
Abstract:: Age-related decline in the capacity of endogenous antioxidant systems complicates pharmaceutical use by the elderly by potentially increasing the toxicity of some compounds. Of particular interest is chemical detoxification via glutathione (GSH) and attendant GSH-requiring detoxification enzymes, e.g. GSH peroxidases (GPX) and GSH S-transferase (GST). These enzymes have been shown...

Creator:: Sampson, David
Abstract:: Lung cancer in humans is an adult-onset disease. It is the number one cause of cancer mortality for both men and women and has a poor (15%) survival rate. Biological markers of the disease would allow for early diagnosis and treatment. The specific aims of this research project were to...

Aluminum Tolerance of Winter Wheat

Creator:: Sadler, Cameron
Abstract:: Wheat is an important part of a healthy and balanced diet, requiring six servings per day to maintain a recommended 2000 Calorie intake (McRae, 2017). Because of this more land than almost any other kind of cereal is set aside for the purposes of growing wheat. To keep up with...

Analysis of boscalid resistance of isolates of Botrytis cinerea

Creator:: Villanueva, Brenda
Abstract:: Succinate dehydrogenase (Sdh) inhibitor fungicides, such as boscalid, are effective for the management of gray mold caused by the fungal pathogen Botrytis cinerea. Unfortunately, resistance to boscalid was common among isolates of the pathogen from small fruits grown in Oregon. Boscalid-resistance is commonly associated with mutations in Sdh, especially in...
