The Psychology Of The Stage: Intersections Of Cognitive Science And Theatre, Ariya Selvakumar
The Psychology Of The Stage: Intersections Of Cognitive Science And Theatre, Ariya Selvakumar
Student Scholar Symposium Abstracts and Posters
By engaging audiences in a stranger’s story, theatre often depends on emotional contagion and empathetic responses to strike interest and investment in characters and their circumstances. Mirror neuron systems are those highly tied to the activation of empathy. These neurons are brain cells that activate when we perform an action and witness an action being performed. For example, when someone is crying, a subset of neurons that fire when we cry will also fire in response to seeing this action, thus often leading to emotional contagion. With an understanding of cognitive science, we can closely examine the perspective-taking and emotion-prediction …

Student Scholar Symposium Abstracts and Posters
Worldwide, more than 38 million people are living with human immunodeficiency virus (HIV), about 84 million people have become infected with HIV since the start of the epidemic, and 40.1 million of those diagnoses led to death. HIV Type-1 is the most common type of HIV, attacking the body’s immune system by destroying CD4 cells. The virus attaches itself to the CD4 cell, taking control of its DNA and replicating itself to release more HIV into the bloodstream. The Gag proteins of HIV-1 are crucial players in the virus’ assembly, release, and maturation; it utilizes its essential matrix protein (MA) …

Analyzing Interactions Of Calmodulin With Hiv-1 Matrix Protein, Andrea Sandoval, D. Mau, N. Karimi, K. Sakamaki, C. Owens, Jerry Larue
Student Scholar Symposium Abstracts and Posters
Human immunodeficiency virus (HIV) attacks the immune system and if left untreated, could cause acquired immunodeficiency syndrome (AIDS). The HIV matrix protein (HIV-MA) is involved in replication and regulation of the HIV virus. Calmodulin (CaM), a calcium-binding protein found in all eukaryotes, has a potential role in the viral replication of HIV-MA which plays a key role in the replication of HIV. In order to investigate the interactions between calmodulin and the HIV-MA, a series of titrations with CaM are performed using circular dichroism. Circular dichroism (CD) uses circularly polarized light to observe the secondary structure of a molecule. The …

Evaluation Of The Trunarc Handheld Narcotics Analyzer As A Pre-Analysis Screening Device For The Orange County Crime Lab, Sarah Yang, D. Bauer, C. Woltz, S. Soto, Michael Ibba
Student Scholar Symposium Abstracts and Posters
Forensic analysis of suspected narcotics is often dangerous as the substances’ composition is unknown. Many techniques for drug identification require handling of the substance outside of its packaging, which can expose the analyst to potentially harmful chemicals. The TruNarc Handheld Narcotics Analyzer is a portable Raman spectroscopy device that is non-destructive of evidence and can be used to screen drugs through simple packaging to minimize the risk of exposure. The Orange County Crime Lab (OCCL) is testing the limits of this device to determine if it can be used to screen new evidence within the Seized Drugs Lab. The OCCL …

Development Of Comprehensive Theoretical Morphospaces For Canine Cranial Morphology, Alexa Ortega, Nicholas Hebdon, Lindsay Waldrop
Student Scholar Symposium Abstracts and Posters
Throughout the evolution of the family Canidae, there is a continuous belief that canines have an exceptional olfactory system which allows them to have a heightened sense of smell. Because of this olfactory sophistication, canines have become prevalent as detection animals in the military, homeland security, law enforcement, forensics, and civilian applications. However, while the trait is highly regarded, the exact role of nasal morphology is understudied. We aim to investigate the influences of nasal cavity and internal structure morphology in odor detection. However, nasal structure is a sophisticated morphological target and requires innovative solutions to capture the key variables …
Fundamental Causes Of Racial And Ethnic Covid-19-Related Health Disparities, Hana Neutz
Fundamental Causes Of Racial And Ethnic Covid-19-Related Health Disparities, Hana Neutz
Student Scholar Symposium Abstracts and Posters
Underserved low-income communities of color in the U.S. have endured an unequal burden of COVID-19 morbidity and mortality. This pattern of pandemic-related health disparities has been pervasive throughout history. However, no known studies have simultaneously examined social and biological factors that contribute to these concerning health disparities. Therefore, this paper aims to bridge the gap by employing a scoping literature review of (1) the deleterious impacts of systemic racism on COVID-19-related outcomes; and (2) the cellular and molecular mechanisms connecting COVID-19 and hypertension (a comorbidity known to exacerbate COVID-19 severity). My findings indicate that systemic racism manifests in inequitable access …

How Covid19 Has Impacted Students Nutrition And Eating Habits With The Abrupt Closure Of Restaurants And Campuses, Chloe Sermet
Student Scholar Symposium Abstracts and Posters
With the ongoing COVID-19 pandemic causing college campuses, restaurants, and businesses to shut down, many college students found themselves having to return home or find alternative food resources. Due to these factors, it was imperative to examine how college student’s eating habits have changed throughout the pandemic, dealing with lots of stressors, and whether having prior education on nutrition influenced those eating habits. To examine those effects, 17 nutrition minors and 126 non-nutrition minors participated in the current study in which they took the College Students Eating Habit survey and the Perception of Peer Pressure Scale. The outcome of the …

Compounded Gabapentin For Felines: Associated Metabolic Processes And Analysis Of Potency, Johnny Altwal
Student Scholar Symposium Abstracts and Posters
Pharmaceutical compounding provides pharmacists and clinicians the opportunity to create unique drug formulations that are better suited to a specific patient’s needs. This is especially prevalent in veterinary medicine where clinicians treat a variety of maladies in a large number of species, thereby requiring unique formulations to more easily deliver drugs to animals. Several examples of compounded veterinary formulations with sub-therapeutic potencies have been published, but none examine compounded gabapentin. Gabapentin is frequently compounded into an oral suspension for veterinary use from tablets or capsules for the purpose of pain management in felines and other small animals. The project’s goals …

Investigating The Interactions Between Individual Calmodulin And Hiv-1 Protein Domains, Riley K. Kendall, Jerry Larue
Student Scholar Symposium Abstracts and Posters
The World Health Organization found that 37.9 million people were living with HIV by the end of 2018. HIV is a virus that weakens the immune system through viral replication and the destruction of CD4+ T-cells, which are white blood cells that detect infection and make antibodies. A cure for HIV has not yet been discovered. HIV-1 contains a Gag polyprotein which regulates the stages of viral replication. Previous studies suggest that the myristoyl group of a matrix protein peptide found on the Gag polyprotein, MA, forms a complex with a calcium-binding, multifunctional regulatory protein called Calmodulin (CaM). CaM …

Future streamflow in California, as predicted by eight climate projections models, and their effects on water availability are discussed in this paper. The unimpaired projected streamflow for eleven California rivers, collected from Cal-Adapt Streamflow are compared with their unimpaired historical flows (1950-2015) using eight climate model projections (2020-2099) developed by Scripps Institution of Oceanography’s Routed Streamflow Projections; Warm Dry RCP 4.5, Average RCP 4.5, Cool Wet RCP 4.5, Other RCP 4.5, Warm Dry RCP 8.5, Average RCP 8.5, Cool Wet RCP 8.5, Other RCP 8.5. Projected drought quantities, durations, and intensities are statistically tested against historical values to determine significance …
The Effects Of Zoledronate And Sleep Deprivation On The Distal Femur Trabecular Thickness Of Ovariectomized Rats: Application Of Different Statistical Methods, Erin Nolte
Student Scholar Symposium Abstracts and Posters
Osteoporosis is a disease that causes the degradation of bone, leading to an increased risk of fracture. 1 in 3 women over the age of 50 will be affected by Osteoporosis. This study aims to understand how bone is affected by sleep deprivation in estrogen-deficient rats, and how Zoledronate might negate the inimical effects of sleep deprivation on bone. As bone mineral density (BMD) is a crude evaluation of the architectural changes seen in Osteoporosis, trabecular thickness may serve as a better single evaluation of bone health. 31 Wistar female rats were ovariectomized and separated into 4 random groups. The …

The Effects Of Gibberellic Acid And Auxin Hormones On Heliotropism In Sunflowers, Brandon Bernardo, Hagop S. Atamian
Student Scholar Symposium Abstracts and Posters
Sunflowers are one of many different plant species that are able to track and face the sun in order to optimize the amount of sunlight they are exposed to. This process of orienting towards the sun is called Heliotropism. Sunflowers are able to effectively orient themselves towards the sun because the growth rate on the East and West side of the stem alternates depending on the time of day. At dawn, the East facing stem will grow at a faster rate than the West facing side, resulting in the flower orienting towards the West. This alternating and uneven growth is …

Fusarium Euwallacea: A Serious Threat To The Native And Ornamental Trees And Shrubs In Southern California, Greg Tyler, Yixing Zheng, Michael Kulinich, Hagop Atamian
Student Scholar Symposium Abstracts and Posters
Fusarium Euwallacea is a fungus that has established symbiotic relationship with the beetle Euwallacea aff. fornicata. The beetle bores through the tree bark and into the sapwood making long tunnels inside the trees. The beetle carries the F. Euwallacea in a specialized structure on its body called mandibular mycangia and cultivates the fungus in the tunnels on which the beetle feeds to grow and reproduce. The growth of the fungus obstructs water and mineral transport in the plant xylem tissue, resulting in dieback, wilt and mortality of the host tree. Fungi are known to secrete proteins called effectors in …

Reporting Charcoal Rot In Chia And Developing A Susceptibility Assay, Reis M. Misaka, Hagop S. Atamian Dr., Julien Besnard Dr.
Student Scholar Symposium Abstracts and Posters
Chia (Salvia Hispanica) cross breeds were planted in the summer of 2018 with the intent of selective breeding for agricultural benefit. Preexisting pathogens in the soil caused 40-50% fatality of adult plants. This was surprising due to the precursory knowledge that chia has antibiotic and antifungal oils (Elshafie et. al. 2018); chia was only recently documented to be susceptible to Fusarium wilt (Fusarium oxysporum). The primary pathogen responsible was identified as Macrophomina phaseolina (aka charcoal rot); a widespread soilborne pathogen which has multiple commercial hosts (Su et. al. 2001).
M. phaesolina on wheat seed vector where used as …

Every 11 seconds, an older adult is treated in the emergency room for a fall; and every 19 minutes, an older adult die from a fall. According to the CDC’s Web-based Injury Statistics Query and Reporting (WISQARS), one in four Americans aged 65+ falls each year. In 2014, the total medical cost of fall injuries was $31 billion. These fall accident and injury statistics may remain unchanged unless an automated highly accurate mechanism for fall risk assessment is available. Having said that, the purpose of this research study is to identify fall prone elderly and prevent fall from occurring. Using …
The Role Of Exosomes In Prostate Field Cancerization, Julie Nguyen
The Role Of Exosomes In Prostate Field Cancerization, Julie Nguyen
Student Scholar Symposium Abstracts and Posters
Field cancerization is formally defined as the presence of molecular alterations in structurally normal tissues adjacent to tumors. Currently, the etiology of prostate field cancerization is still unknown. We hypothesize that exosomes (vesicles excreted by cells that may contain protein, lipids, or RNA) are released by tumors and are endocytosed by adjacent normal cells converting them into abnormal cells, thereby aiding cancer progression. The following biomarkers have been associated with field cancerization: MIC-1, PDGF-A, FASN, and EGR-1, while markers for exosomes are CD-9, CD-63, and PSMA. To test this hypothesis, exosomes were isolated from human prostate cancer cell models LNCaP …
Breeding Stage And Parentage Affect Tameness In Common Loons, Mina Ibrahim
Breeding Stage And Parentage Affect Tameness In Common Loons, Mina Ibrahim
Student Scholar Symposium Abstracts and Posters
Tameness is a measure of tolerance towards human disturbance. As human disturbance and recreational activity are increasing, it is becoming more and more important to understand responses of species to this disturbance. Tameness has been shown to be influenced by an individuals characteristics and life history. Two possible determinants of tameness are breeding stage and parentage. We studied tameness in common loons (Gavia immer) specifically looking at the effects of breeding stage and parentage. Tameness was measured by flight initiation distance (FID), the distance at which a loon dove from an approaching human observer in a canoe. Loons …

Manual And Automated Solid Phase Synthesis Of Peptides For Breast Cancer Cell Targeting, Savannah Carlson
Student Scholar Symposium Abstracts and Posters
Four peptides were synthesized using solid phase peptide synthesis. The two target peptides synthesized were based off peptide 18-4 and its negative analog. Each were synthesized once manually, and once using an automatic peptide synthesizer. Peptide 18-4 has a high affinity for breast cancer cells, allowing it to be used to detect circulating tumor cells (CTCs) in blood (Kaur et. al, 2015). Manual solid phase peptide synthesis is performed by anchoring the first amino acid to Wang resin and coupling each Fmoc protected amino acid individually until the target sequence is achieved. To synthesize the peptides automatically, the automated Tribute …

Gluten-Free And Casein-Free Dietary Intervention For Children Diagnosed With Autism Spectrum Disorder, Avalon Derlacki
Student Scholar Symposium Abstracts and Posters
In the United States, autism spectrum disorders (ASD) had a prevalence of 1 in 150 children in 2000. In the year 2012, the prevalence of ASD in the United States jumped to 1 in 68 children (Centers of Disease Control and Prevention, 2012). Due to the increase in diagnoses of ASD, researchers have sought out different ways to help decrease maladaptive symptoms associated with ASD’s. Many parents of children diagnosed with ASD administer a gluten-free and casein-free (GFCF) diet to their children in hopes of reducing their maladaptive symptoms. The project hypothesis states that if a child under the age …

A Pilot Study Analyzing Solvents In Electronic Cigarette “E-Liquid” Using High Performance Liquid Chromatography, Austin Matranga, Olivia Sellers, Matthew Gartner
Student Scholar Symposium Abstracts and Posters
Introduction: Electronic cigarettes, also known as an e-cigarette, are battery-powered devices that use a heating element to convert a liquid (“e-liquid”) into an inhalable aerosol. Their advertised use is as a nicotine delivery system minus the harmful chemicals. Since “e-liquids” and the electronic cigarettes are not regulated by the Food and Drug Administration, it is not well known under what conditions, if any, carcinogenic compounds are produced. There has been little research on the toxicity of electronic cigarettes. The aim of this study was to determine if formaldehyde or acetaldehyde are formed from the e-liquid by the high heat of …

Connecting The Physiological And Behavioral Response To Heat Stress On A Warming Planet, Anastasia Kalyta
Student Scholar Symposium Abstracts and Posters
Intertidal communities are considered good models of the biological effects of climate change on ecosystems, as their resident organisms are subjected to heat spells during daytime low tides. The increasing heat exposure can elicit behavioral as well as physiological responses in intertidal organisms. We studied the relationship between these responses to heat stress in the blue-banded hermit crab, Pagurus samuelis, by inducing a “heat shock” with elevated water temperature of 29 °C for 2.5 h. The behavioral effect of heat-shock was quantified using a 30-minute feeding assay, measuring the mass of a standard squid pellet consumed by individual hermit crabs. …

Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun, William G. Wright
Student Scholar Symposium Abstracts and Posters
One of the most destructive effects of global climate change is the increased carbon sequestering and consequential acidification of our world’s oceans. The impacts of ocean acidification on marine organisms are still relatively unknown, especially effects on behavioral ecology. Avoiding predation has emerged from recent behavioral ecology literature as a critical feature in the life history of a wide array of animal species; experiments on marine fishes suggest acidic water compromises their predator-avoidance abilities. Recent assays in our lab suggest predator-induced behavior is reduced by weakly acidic water. These experiments do not address the potential factor of generalized malaise caused …

Student Scholar Symposium Abstracts and Posters
Oxygenated hydrocarbons are ubiquitous in the atmosphere with levels ranging from low ppt (acetaldehyde) to low ppb (methanol). As an OH sink and an atmospheric HOx and ozone source, oxygenated hydrocarbons have a direct impact on the oxidative capacity of the atmosphere. The oceans are one of the largest sources of uncertainty in current atmospheric budget estimates of these species. A better understanding of the processes that produce and destroy these species in seawater would improve our understanding of the role of the oceans in cycling these species into or out of the atmosphere. We have measured the degradation rate …
