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...

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...

Understanding polycyclic aromatic hydrocarbon (PAH) toxicity and inflammation in human bronchial epithelial cells

Creator:: Valdez, Teresa
Abstract:: There is increased emphasis on understanding cumulative risk from the combined effects of chemical and non-chemical stressors as it relates to public health. Recent animal studies have identified pulmonary inflammation as a possible modifier and risk factor for chemical toxicity in the lung after exposure to inhaled pollutants; however, little...

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...

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...

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...

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...

Impact of Polycyclic Aromatic Hydrocarbons on Barrier Function Toxicity in 3D Lung Model from Normal and Asthmatic Donor Cells

Creator:: Huynh, Celine T.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are known to cause adverse health effects in the human lung. Here, we evaluated biomarkers relevant for PAH toxicity in a 3D human primary bronchial epithelial cell (HBEC) model collected from normal and asthmatic donors. We previously found that PAHs decrease cellular barrier function integrity, which...

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...

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...
