Abstract 1: “Mechanics of Jaywalking”.  Insiya Nehal, Geana Nicolas, Esmeralda Vazquez and Vanshika Sangal (advised by Dr. Cara Wall-Scheffler, Dept. of Biology). Abstract: This projects aimed to observe change in speed among individuals who attempted to jaywalk or participated in other pedestrian activities. Other factors were taken into consideration such as load carrying, companions, gender, traffic, time of day, or general surroundings. This was done to see how locomotion is affected by different variables and how it affects daily human decision making.

Abstract 2: “Investigating how Mycoplasma genitalium adapts to 5-Nitroimidazole antibiotics through genomic sequencing”.  Alessandro Rizzi, Cameron Weller and Abhi Kancherla.  Abstract: Mycoplasma genitalium (Mg) is an emerging sexually transmitted pathogen that causes urethritis in men and pelvic inflammatory disease in women. In recent years, antibiotic-resistance in Mg has increased. 5-Nitroimidazoles were recently shown to be effective against Mg and are being explored as alternative treatments. In this study, we examined 5-nitroimidazole resistant mutants using MINion whole genome sequencing. We identified several mutations and specifically discuss those in Mg_342, which encodes FMN reductase.

Abstract 3: “Genetic Origins of 5-Nitroimidazole Resistance in Mycoplasma genitalium G37S”.  Helena Huong Nguyen, Leanne Binas and Vaughn Poon.  Abstract: Mycoplasma genitalium (Mg) is a sexually transmitted pathogen that causes urethritis in men and pelvic inflammatory disease in women. It is developing resistance to current first-line antibiotics making the discovery of alternative treatments important. 5-nitroimidazoles were recently shown to kill Mg at physiologically relevant concentrations. We investigated the resistance mechanisms of Mg to 5-nitroimidazoles using MinION sequencing revealing a mutation in the gene coding for the NADPH-dependent FMN reductase discussed here.

Abstract 4: “Genomic Analysis of Aggregated Mycoplasma genitalium Strains Locked with Codon-Modified Variable Regions“.  Julia Gill, Mariah Kelley, Chris Penner and Tyler Speer.  Abstract: Mycoplasma genitalium (G37) is a sexually transmitted pathogen responsible for many urogenital diseases. To promote immune evasion, the pathogen undergoes antigenic and phase variation, occurring through homologous recombination between the MgPa operon and nine MgPars. To investigate the effect of decreased antigenic variation on infection persistence, G37L2 was created to reduce homologous recombination. Surprisingly, serial passage of G37L2 formed non-adherent aggregates, prompting investigation into the genomic rationale for this phenotype.

Abstract 5: “Antibodies are a Selective Force for Antigenic Variation in Mycoplasma genitalium”.  Dev Subramanie, Sukhi Lidder, Xing Z. Huang and Kathryn VanMaanen. Abstract: Mycoplasma genitalium causes persistent infection in the human reproductive tract. Its antigenic proteins, MgpB and MgpC, are expressed by the MgPa operon. MgPa undergoes antigenic variation, altering MgpB/C’s shapes. Bacterial samples from two infected pig-tailed macaques were sequenced to examine the role of antibodies in antigenic variation. Only one macaque produced antibodies against MgpB/C. We found more antigenic variation in bacteria growing in the presence of antibodies, suggesting that antibodies select for antigenic variation.

Abstract 6: “Monoterpenes in Mainland and Blakely Island tree species”.  Gum Nau, Hannah McSwain and MacKenzie Garrett (advised by Dr. Ryan Ferrer). Abstract: Many plant species exhibit chemical defenses that are induced by herbivore damage, constitutively regardless of damage, or both with different chemicals serving complimentary defensive functions. Monoterpene production in some evergreen tree species appears to be induced by environmental conditions, including herbivore damage. Douglas fir (Pseudotsuga menziesii), western redcedar (Thuja plicata), and lodgepole pine (Pinus contorta) are widely distributed across western Washington and are abundant in the San Juan Islands. Blacktail deer (Odocoileus hemionus columbianus) exhibit intense browsing pressure on these and other plant species, especially on Blakely Island, where deer densities far exceed those of mainland populations. Here, we survey the presence, absence, and concentrations of four representative monoterpenes: α-pinene, β-pinene, limonene, and β-caryophyllene in these three evergreen species on Blakely Island and at an urban, mainland park where deer density is low.

Abstract 7: “Coral Restoration Efforts in Les Village (Bali, Indonesia)”.  Krysta Reese (advised by Dr. Tim Nelson, Dept. of Biology).  Abstract: This project investigates four aspects of coral reef restoration efforts in Les Village. Survivorship based on species and depth was determined for nursery-grown corals. Micro-fragment transplants of several boulder coral species were measured to evaluate growth in two years. New Acropora (a branching coral) transplants were measured to be re-evaluated in two years. Lastly, the success of previous restoration projects were analyzed by tracking the abundance of butterflyfish at different treatment sites.

Abstract 8: “The Analysis of Salmon DNA as an Indicator of Mislabeling Rates in ɬ�﷬ Sushi Restaurants”.  Hannah Buller and Eloisa Nguyen (advised by Dr. Tracie Delgado, Dept. of Biology).Abstract: Salmon mislabeling is prevalent in the food industry, contributing to false advertisement of salmon species such as substituting a cheaper species in place of an expensive species. Self-classified salmon from sushi restaurants in ɬ�﷬ were identified using molecular methods (PCR, gel electrophoresis, DNA sequencing, etc.). The goals of our research project are to 1) determine salmon mislabeling rates and 2) determine the substitution rate of salmon for another fish species in ɬ�﷬.

Abstract 9: “Salmon Mislabeling Rates at Sushi Restaurants in ɬ�﷬”.  Griffin Ovenell and Lay Paw (advised by Dr. Tracie Delgado, Dept. of Biology).  Abstract: ɬ�﷬ prides itself on its quality of salmon. However, mislabeling of salmon species can occur when salmon is served to the consumer such as advertising wild caught salmon but serving farmed salmon. In this study, salmon samples were collected from sushi restaurants from across ɬ�﷬ to determine mislabeling. The species was determined by sequencing the genome using a polymerase chain reaction (PCR) then comparing the product DNA to a genome database.

Abstract 10: “ɑ-Difluoromethylornithine (DFMO) as an FDA approved metabolic inhibitor in gammaherpesvirus replication”.  Jasmine Vo and Lay Paw.  Abstract: Viruses play a role in as many as 10-15% of all human cancers. Murine gammaherpesvirus-68 (MHV-68) is a natural pathogen that infects mice and shares homology with several human herpesviruses. The Delgado lab shows an alteration of metabolism in MHV-68 infected cells. Metabolomic data shows an increase in polyamine metabolism in infected cells. ɑ-difluoromethylornithine (DFMO) is a clinically relevant metabolic inhibitor drug that blocks polyamine production. This project investigates DFMO as a potential MHV-68 inhibitor.

Abstract 11: “Wild or farmed? - Salmon mislabeling in sushi restaurants within the ɬ�﷬-metropolitan area”.  Jewel Garcia (advised by Dr. Tracie Delgado, Dept. of Biology). Abstract: Among many aspects, ɬ�﷬ is also known for its salmon. Though many sushi restaurants tend to market their salmon as a specific species, such as king or coho, these restaurants could mislabel their salmon for various reasons. By acquiring samples from sushi restaurants in the ɬ�﷬ area, conducting PCR, and DNA sequencing, our research compares the DNA of each sample to its public advertisement in one of America’s most reputable salmon hotspots.

Abstract 12: “Effects of Leflunomide on Murine Herpesvirus 68 (MHV-68) Lytic Production”.  Peter Nalivayko and Helena Huong Nguyen.  Abstract: Murine Herpesvirus-68 (MHV-68) is a suitable model for studying viral lytic replication in vitro. The Delgado lab’s metabolomics screen revealed an increase in nucleotide production in MHV-68 infected cells. Leflunomide (LF) is an FDA-approved drug that inhibits de novo pyrimidine synthesis. We investigated LF effects on MHV-68 lytic production in NIH-3T3 cells and found a significant drop in viral production in the LF-treated cells, opening up the possibility of LF as an antiviral medication.

Abstract 13: “Murine Herpesvirus 68 (MHV-68) infection increases glucose metabolism to promote viral production”.  Madeleine Splattstoesser.  Abstract: Our lab studies Murine Herpesvirus 68 (MHV68) as a model for understanding how oncogenic human herpesviruses alter host cell metabolism to promote viral replication. Previous metabolomics research done in our lab revealed that the host glycolysis pathway is upregulated during viral infection. The goals of this project are 1) determine if glycolysis is increased in MHV-68 infected cells and 2) determine if glucose starvation or glycolytic inhibitor drugs block virus production.

Abstract 14: “Efficiency of Leflunomide on Inhibiting MHV-68 Viral Production“. Vanshika Sangal. Abstract: Murine gamma herpesvirus 68, a naturally occurring pathogen of rodents, is a model system used to study how related human herpesviruses cause cancer. A recent metabolomics study in the Delgado lab showed an increase in nucleotide metabolites during MHV-68 infection of host cells. Leflunomide is a clinically relevant drug that inhibits nucleotide production. The goals of this project are to determine if leflunomide treatment blocks MHV-68 production and may be used as an antiviral treatment.

Abstract 15: “Spatial Comparisons in the Behavior and Movement of ‘Sounders’ Gray Whales in Possession Sound, Washington”.  Sara Mach (advised by Dr. Eric Long, Dept. of Biology).  Abstract: Every spring, a small group of benthic feeding gray whales, nicknamed the “Sounders,” come to Possession Sound and the surrounding waters to feed on ghost shrimp that live in the sediment throughout the intertidal zone. This research evaluates and combines fourteen years of sighting data from the Ocean Research College Academy (ORCA) with the intent of identifying spatial patterns in gray whale movement and possible correlations with the tides.

Abstract 16: “Antibody Reactivity of Primate Sera to Mycoplasma genitalium Adhesin Proteins”.  Ethan Wood (advised by Dr. Gwen Wood, University of Washington). Abstract: Mycoplasma genitalium is a sexually transmitted pathogen that persists in patients despite the presence of serum antibodies. Antibodies to M. genitalium were collected from infected female pig-tailed macaques and bacterial load was measured. The appearance of M. genitalium-specific antibodies in cervical secretions coincided with decreased bacterial load. The antibodies recognized the MgpB and MgpC adhesin proteins. By using ELISAs we hope to determine which segments of these proteins are targeted by an effective antibody response.

Abstract 17: “Glucose and fructose differentially regulate microglia-neuronal interactions​”.  Itzel Aparicio (advised by Dr. John Douglass, Dept. of Biology).  Abstract: Alzheimer’s disease involves metabolic changes in the brain such as buildup of carbohydrate fructose. It is unclear whether excess fructose impacts neurons and non-neuronal cells that may influence cerebral function. We used in vitroculture of BV-2 microglia, N43/5 neuronal cell lines and different concentrations of glucose and fructose. Our results indicate that microglia exhibit metabolic flexibility in carbohydrate usage, but that fructose specifically induces a neurotoxic phenotype that may ultimately impair brain health.

Abstract 18: “Relationship Between Maladaptive Behaviors Induced by Chronic Stress and Glial Inflammation“.  Jakob Wilson (advised by Dr. John Douglass, Dept. of Biology). Abstract: Stress has long been known to influence mood and is linked to increased risk of maladaptive behaviors that include suicidal ideation. The neurological mechanism by which this occurs is not yet understood. In this research, we use a rodent stress model and immunofluorescent microscopy to explore whether astrocytes and microglia undergo conformational changes indicative of inflammation that occur in key brain areas that regulate mood and decision-making behaviors.

Abstract 19: Stress Induces Glial Inflammation in Rat Brains Represented by Immunofluorescent Staining“.  Mariah Kelley and Milan Brkic (advised by Dr. John Douglass, Dept. of Biology and Dr. Phillip Baker, School of Psychology and Family Counseling).  Abstract: Chronic stress is linked to suicidal behaviors in humans, but the neurophysiological mechanisms are not fully understood. Rat models exposed to intermittent and chronic stressors were used to investigate whether stress induces inflammation in specific brain regions. Cells like astrocytes and microglia in the nucleus accumbens were analyzed through immunohistochemical staining in post-mortem brains. Results help us understand neurological links between stress and self-harm, and potentially identify therapeutic targets to treat stress-related mental health disorders.

Abstract 20: “Machine Learning Analysis for Species Differences in Predator-Exposed Rodents”.  Hoda AbouEich, Bailey Wells and Michael Mains (advised by Dr. Phillip Baker, School of Psychology and Family Counseling).  Abstract: Using machine learning analysis, we analyzed both rats and mice of different strain, sex, age, and housing in order to evaluate behavioral differences in exposure to a 3D printed owl predator that surges towards the center of an arena. As the rodent responded to the stimulus, we were able to evaluate behavioral patterns, such as time spent in hiding, freezing, fleeing, or near the walls of the arena. This will allow us to look at the overall movement trajectories prior to and during predator exposure across species.

Abstract 21: “Effects of NMDA Inhibition on Rodent Decision-Making and Reward-Seeking Behavior”.  Seth Foust, Hoda AbouEich, Bailey Wells, Michael Mains, Brandon Goh and Hannah Doble (advised by Dr. Phillip Baker, School of Psychology and Family Counseling). Abstract: In this study, we are investigating how NMDA receptor antagonists affect decision-making in Sprague Dawley rats. Rats were trained to choose between levers that dispense sugar pellets at fixed or progressive increased intervals, and then given varying doses of MK-801 (0.06 ml/g, 0.1 ml/g, 0.2ml/g) or saline as a control. We are analyzing how the rats' behavior relates to optimal choices in the task with each dose of MK-801. These findings could help improve our understanding of how NMDA receptor antagonists affect decision-making and reward-seeking behaviors.

Abstract 22: “Relationship Between Sex and MK-801's Effects on Rats”.  Erica Sanchez, Emily McCurry and Seth Foust (advised by Dr. Phillip Baker, School of Psychology and Family Counseling).  Abstract: In this study, we are investigating the effects of MK-801 on male and female Sprague Dawley rats. According to D’Souza et al. (2001), females have a stronger reaction to MK-801 than males. Correspondingly, the current study measures the varied effects of MK-801 on rat models using an optimal decision-making task. The rats are injected with doses of MK-801. Then, they choose between a Fixed-Delay (FD) (ten-second intervals) and a Progressive-Delay (PD) lever (one second progressive increase) to receive rewards. We are currently in the process of obtaining results analyzing the relationship between sex and MK-801’s effects.

Abstract 23: “Odor discrimination in response to different forms of intentional focus stimuli”.  Jewel Garcia (advised by Dr. Ryan Ferrer, Dept. of Biology).  Abstract: Humans have an incredible ability to differentiate odor mixtures. Both the peripheral and central nervous systems play a role in human olfaction, receiving odors and interpreting odor combinations and environmental contexts, respectively. We tested whether short-term mindfulness meditation increases odor discriminatory ability compared to stimulated distraction through gameplay. We also predicted that increasing odor mixture overlap would decrease discriminatory ability.

Abstract 24: “Utilizing DNA Barcoding Analysis in Salmon Species to Identify Potential Mislabeling in Sushi Restaurants in ɬ�﷬”.  Lauryn Keith (advised by Dr. Tracie Delgado, Dept. of Biology).  Abstract: The potential mislabeling of salmon in sushi restaurants, such as substituting less expensive species like farmed for wild-caught, is a prevalent issue. The aim of my research is to investigate this matter in ɬ�﷬ sushi restaurants and compare the results with previous studies conducted in the USA. The utilization of DNA isolation, PCR, and sequencing techniques will enable the identification of salmon species through DNA barcoding.

Abstract 25: “Genomic analysis of a variety of salmon samples from various sushi shops in ɬ�﷬”.  Andre’ Marineau (advised by Dr. Tracie Delgado, Dept. of Biology). Abstract: A group of researchers from ɬ�﷬ collected a variety of either wild caught or farmed Salmon samples in the city of ɬ�﷬. The validity of the claimed salmon species was then determined through isolating the Salmon’s DNA, amplifying the obtained DNA through PCR and then sending it to Fred Hutch for genomic sequencing. The resulting sequences were then examined to the claimed Salmon species genomic sequence through Finch TV.
