Abstract:: Hypoproteinemia secondary to gastrointestinal disease in horses has traditionally been treated with the administration of colloids such as equine plasma or hetastarch. While plasma transfusion is common, evidence-based guidelines for its use in hypoproteinemic horses are lacking. This study involved prospective and retrospective components that aimed to weigh the efficacy...

The Adverse Effects of Diurnal Light Exposure on Aging Drosophila melanogaster

Creator:: Nash, Trevor N.
Abstract:: The proliferation of light emitting diodes (LEDs) are increasing human light exposure, yet the long-term effects of such exposure remains unknown. The current study aims to address this by measuring the longevity of Drosophila melanogaster kept in several light conditions. Initial longevity testing determined that flies kept in daily light-dark...

Stress and Learning in Larval Zebrafish (Danio rerio)

Creator:: Moussaoui, Bushra
Abstract:: In this study, we characterize the behavioral response of larval zebrafish (Danio rerio) to the noxious chemical allyl isothiocyanate (AITC), an agonist of the nociceptive TRPA1 ion channel, and utilize AITC as an aversive stimulus in an associative learning paradigm. We find that larvae exposed to AITC in both a...

Adaptation to long-term osmotic stress in Saccharomyces cerevisiae

Creator:: Gosman, Andreea
Abstract:: An important goal of evolutionary biology is to identify the genetic mechanisms underlying phenotypes in organisms. Understanding adaptation to osmotic stress has many applications, since this stress affects almost all organisms on Earth. By studying the model organism Saccharomyces cerevisiae using experimental evolution, we can learn about genetic mechanisms driving...

Death, Disorder, and Other Human Terrors

Creator:: Gollihugh, Breanna M.
Abstract:: Storytelling has been a key societal element for hundreds of years. Over time it has evolved from tales spread by word-of-mouth, to printed words, and most recently to worldwide digital platforms. Stories, and their ability to be both shared and coveted, make them a truly unique aspect of the human...

Predicting Fish Recruitment in the Northeast Pacific Using Climate Indices

Creator:: Riley, Shannon L.
Abstract:: Predicting recruitment, which is dependent on parent stock size and climate, is vital for forecasting productivity of fish stocks. The effects of climate can be analyzed via the use of climate indices. Three climate indices, the Pacific Decadal Oscillation, the North Pacific Gyre Oscillation, and the Oceanic Niño Index, describe...

The Doctor-Patient Relationship: How a Physician Navigates Clinical Empathy and Patient Death

Creator:: Smith, Hannah R.
Abstract:: As the importance of empathy in medicine has become more understood the dynamic of the patient-doctor relationship has changed. However, how to properly incorporate empathy into a healthcare relationship has not been thoroughly investigated. There is also continued disagreement on how to appropriately define empathy in a healthcare setting. The...

Impact of Time and Temperature on Ex Vivo and Postmortem Diagnostic Assays

Creator:: Wachtel, Kaitlyn E.
Abstract:: Postmortem diagnostics play an important role in the ability to understand the cause of death of an animal. However, removal from oxygen supply, either by surgical excision or at death, leads to cell and tissue decomposition. Knowledge about factors impacting reliability of test results is extremely important for accurate diagnostics....

Identification of Pseudomonas syringae genes required for perception of host-derived virulence-inducing metabolites

Creator:: Turner, Sydney E.
Abstract:: Pseudomonas syringae is a Gram-negative bacterium that can infect a variety of important crops. Infection by P. syringae is dependent on a type III secretion system (T3SS) that delivers effector proteins to plant cells to suppress host defenses. Previous work has shown that, in the presence of simple sugars, specific...

Analysis of Alternative Donor Breast Milk Pasteurization Techniques and Their Impact on Bile Salt-Stimulated Lipase Activity

Creator:: Victor, Ashley F.
Abstract:: While breast milk is considered the best nourishment for newborns, they have a lowered ability to digest the fat rich liquid due to decreased lipase secretion for the first few months after birth. To offset this, breast milk itself contains Bile Salt-Stimulated Lipase (BSSL) which significantly heightens fat digestion ability....

A Dysfunctional System: Policy Recommendations for the Adult (18-65) Homeless and Severely Mentally Ill Population in Oregon

Creator:: Miller, Donielle F.
Abstract:: Adults with severe and persistent mental illness (SPMI) are overrepresented in the homeless population, and Oregon’s homeless population has expanded in recent years. In the 1950s, the mentally ill were moved out of the state hospitals and into the community. However, due to a lack of support services in the...

Light Transmittance Properties of Biological Tissues of the Red-sided Garter Snake, Thamnophis sirtalis parietalis, Between 450 and 850 Nanometers

Creator:: Bixby, Eric M.
Abstract:: Using a spectrometer and photomultiplier tube, I measured the electromagnetic radiation transmittance properties of three types of tissue-- ventral skin, cardiac muscle, and liver tissue--in the red-sided garter snake Thamnophis sirtalis parietalis between the wavelengths of 450 and 850 nanometers (nm). Control readings were taken using a 10⁻² neutral density...

Visualizing nuclei in Platygyra daedalea

Creator:: Sakulsakpinit, Minnie N.
Abstract:: Platygyra daedalea, a species of brain coral from the Persian Gulf, can withstand higher temperatures than other coral species. This attribute makes the species a potential model organism for thermal tolerance research. Genomic resources such as a linkage map of this species predict that there are 12 to 14 chromosomes...
