Differences in dry matter production and nitrogen uptake and partitioning among spring wheat (Triticum Aestivum L.) varieties

Creator:: Hitchcock, Todd
Abstract:: Grain protein concentration of wheat is influenced by numerous factors. When determining a wheat variety's ability to produce protein, the plant's ability to uptake and translocate nitrogen is critical. A greenhouse study was conducted to assess differences in nitrogen use among different wheat varieties. The objective was to determine if...

Genotyping Cytochrome P450 1B1*3(Phase I) and Glutathione S-transferase Mu 1 null (Phase II), Metabolizing Enzymes in a [14C]Benzo[a]pyrene Human Micro Dosing Study

Creator:: Luo, Yun L.
Abstract:: Polycyclic Aromatic Hydrocarbons (PAHs) have been studied for their carcinogenic toxicity. PAHs are formed by incomplete carbon combustion. Benzo[a]pyrene (BaP) is an IARC classified Class 1 Human carcinogenic PAH. New studies are conducted to gain a better understanding of PAHs and how to reduce exposure. Glutathione S-transferase M 1 (GSTM1...

Whole system perspective : Steelhead, Onchorhynchus mykiss, glutathione s-transferase as a biomarker of chlorpyrifos exposure

Creator:: Pecore, Rachael G.
Abstract:: Organophosphate insecticides may produce sublethal, adverse effects on salmonid growth, reproduction, maturation, swimming, and feeding. Chlorpyrifos, an organophosphate insecticide, was detected by the Oregon Department of Environmental Quality in the Hood River and tributaries during March 1999 at levels exceeding state water quality standards in the range of 0.011-0.482 μg/L....

Characterizing PM2.5 with Different Source Contributions

Creator:: Perez, Allison Mae S.
Abstract:: Ubiquitous fine particulate matter (PM2.5) exposures significantly impact global public health, yet little is known about the mechanisms causing these known adverse health effects. Oxidative stress due to PM2.5 associated chemical constituents, such as polycyclic aromatic hydrocarbons (PAHs), is a proposed possible mechanism for PM2.5 mediated health effects. Variations in...

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 Comparative Analysis of Mercury and Lead in Sindoor from the U.S. and Bangladesh

Creator:: Breen, Anna K.
Abstract:: Heavy metals have historically been popular for use in cosmetics manufacturing due to the colorful pigmentation of heavy metal compounds. In the case of sindoor, a cosmetic used by married Hindu women for religious purposes, mercury sulfide, lead tetroxide, and lead chromate are compounds suspected to still be involved in...

Invest in Vegetables: A Cost and Benefit Analysis of Container Grown Roma Tomatoes (Solanum lycopersicum cv. ‘Roma’) and Italian Basil (Ocimum basilicum cv. ‘Italian’)

Creator:: Spofford, Tyler S.
Abstract:: The COVID-19 pandemic highlighted disparities in land access and food security. Research has shown that access to gardening reduces financial burdens on low-income households. Compared to homeowners, individuals and families in rental housing face added barriers to vegetable gardening and growing food. These barriers include rental housing regulations and the...

An Evaluation of Staffing Needs at the Health Clinic in Maunatlala, Botswana

Creator:: Bedge, Sonya S.
Abstract:: As part of the Botswana Global Learning Internship Program, a qualitative study was conducted regarding the current staffing conditions at the local village health clinic in Maunatlala, Botswana. This was a month-long project conducted over the summer of 2018. Students from Oregon State University lived in the village of Maunatlala...

Investigating a Role for DNA Mismatch Repair in Signaling a Benzo[a]pyrene Diol Epoxide-Induced DNA Replication Arrest, Investigating a Role for Mismatch Repair in Activating a Benzo[a]pyrene Diol Epoxide-InducedS-phase Checkpoint

Creator:: Coburn, Jacki L.
Abstract:: Genetic and environmental factors influence individual cancer risk. Mutations in DNA mismatch repair (MMR) genes increase colon cancer risk. Exposure to carcinogens, including the ubiquitous polycyclic aromatic hydrocarbons (PAHs), also is associated with increased cancer risk. To understand the combined effects of both environmental exposures and genetic risk, we investigated...

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...
