Utilization of structure-activity-relationship for predicting chemical toxicity in primary human lung cells

Creator:: Galbreath, Amanda
Abstract:: There is a growing need to establish alternative approaches for assessing hazard from chemical exposure compared to the traditional method of animal testing. Approaches that relate chemical structure to biological activity are gaining acceptance in the field as in silico methods for characterizing and predicting chemical toxicity. In this study,...

Development of a diagnostic assay for Phytophthora ramorum lineage detection

Creator:: Roig-Paul, Mireia
Abstract:: Phytophthora ramorum is the causal agent of Sudden Oak Death (SOD), which is an economically and environmentally important disease causing up to 80% mortality of tanoaks in Pacific Northwest coastal forests (LeBoldus et al., 2022). There are currently four clonal lineages in the United States and Europe, named North America...

Anti-Mullerian Hormone (AMH) Levels Are Reduced by Age, But Do Not Correlate With Pregnancy In Timed-Mated Rhesus Monkey Females (Macaca mulatta)

Creator:: Roth, Maggie
Abstract:: Infertility is an issue affecting millions of women across the globe, yet the causes are not fully understood, and treatment options are often ineffective. The evaluation of reproductive hormones has been a common tool used by fertility clinics as a way to predict the ovarian response to treatment and gain...

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...

Monitoring Resistance in Onion Thrips to Insecticides, Lannate® and Exirel®, in the Treasure Valley of Eastern Oregon and Southwestern Idaho

Creator:: Sanchez, Kevin
Abstract:: To evaluate and monitor insecticide resistance in onion thrips Thrips tabaci on onion (Allium cepa), we conducted a study using three field populations in the Treasure Valley of eastern Oregon and southwestern Idaho using the insecticides Lannate (methomyl) and Exirel (cyantraniliprole). To evaluate these two insecticides, biological assays were conducted...

VOC Emisions and Categorization in Axenic Growth Conditions by Phaeodactylum tricornutum

Creator:: Thompson, Douglas A.
Abstract:: Volatile organic compounds (VOCs) play an integral role in climate change and as a carbon source for organisms living in a marine environment. These compounds have many sources, but the impacts of biogenically produced VOCs is not fully known. Phaeodactylum tricornutum was studied under axenic ideal growth conditions to determine...

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...

Changes in Otolith Shape in Juvenile Chinook Salmon in Different Hatchery Rearing Conditions

Creator:: Ehrke, Melissa A.
Abstract:: The decline of the Chinook Salmon has been a mystery of recent years due to their decline. It has been speculated that wild origin salmon have more vigor and survivability than hatchery reared fish. This is thought to be due to rearing conditions, possibly affecting sensory organ development. The sensory...

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...

Guinea pig model of mild hyperandrogenemia – is it a suitable model for women with polycystic ovary syndrome (PCOS)? A pilot study

Creator:: Barboza Sagrero, Juriana E.
Abstract:: Polycystic Ovary Syndrome (PCOS) is an idiopathic disorder prevalent in ~5-10% of reproductive-aged women. In PCOS women who become pregnant, many experience complications including increased susceptibility of having a miscarriage, high blood pressure, and gestational diabetes, among others. Additionally, exposure to PCOS may have transgenerational impacts: offspring may be at...
