Using 3d Modeling To Describe The Electromotility Of The Outer Hair Cell Protein Prestin, And Its Role In Sound Perception Among Mammals, Marqus Colon, Syed Hussain, Russel Robert Reside

Undergraduate Student Symposium

Prestin is a vital motor protein that enables auditory perception in mammals by modulating the shape of cochlear outer hair cells (OHCs) in response to environmental voltage. Part of the SLC26A5 anion transporter family, prestin excels at binding anions, which facilitates its oscillation through unique conformations. While salicylate has been demonstrated to induce reversible inhibition in prestin, the broader mechanisms of how this protein senses and transduces voltage into cellular movement are not fully understood. Crucial to sound amplification in the cochlea and the ability for OHCs to selectively respond to different sound frequencies is non-linear capacitance (NLC), wherein conformational …

Using Physiochemical Properties Of Phenylalkylamines In Silico As A Predictive Classification Of Psychedelic Effect, Tatum Hedrick, Caleb Siguenza

Undergraduate Student Symposium

Rationale: Substituted phenethylamines have been widely used and distributed for religious, therapeutic, and recreational purposes. While some correlations have been reported on small subsets of these molecules and their action, little is known about the fundamental basis of their action at an atomic level. As such, collecting a large collection of computationally predicted physiochemical properties of these compounds in a comprehensive database can serve to aid in predicting their mechanisms of action. Knowing this will ultimately reduce harm among recreational users and increase efficacy in personalized therapies. As such this study aims at establishing a relationship between the calculated atomic …

What Is Categorized As A War Crime Depends On Who Commits It: An Asymmetry In Moral Judgments Of Acts Of War, Alexis Lass

Undergraduate Student Symposium

Should all acts of aggression carried out in war be categorized as War Crimes? The Geneva Conventions and the International Criminal Court set specific parameters as to what does and does not constitute a war crime. Research in the domain of moral psychology displays that individuals are guided by the justness of cause when making moral judgements about combatant behavior. However, minimal research has evaluated the differentiation of atrocities being categorized as a war crime or not. Across two studies, this research seeks to investigate the role aggressors play in lay people’s categorization of war crimes. Do pre-existing beliefs about …

Repurposing Renin-Angiotensin System-Targeting Medications For Later Stage Treatment Of Cerebral Amyloid Angiopathy And Associated Cognitive-Behavioral Deficits In Tg-Swdi Mice, Ariana Hernandez, Chana Vogel, Iliana Uribe, Eleanor Wind, Victoria Pulido-Correa, Mikayla Jeneske, Bianca Echeverria, Julianna Bonetti, Natalia Noto

Undergraduate Student Symposium

Cerebral amyloid angiopathy (CAA), the accumulation of amyloid proteins in the cerebral vasculature, is highly comorbid with Alzheimer’s disease, and on its own, increases the risk of stroke and vascular dementia. Epidemiological studies suggest that certain renin-angiotensin system (RAS)-targeting drugs, commonly used for treating hypertension, decrease the risk of dementia. This study assesses whether two FDA-approved RAS-targeting drugs: telmisartan [a moderately brain-penetrant angiotensin receptor blocker (ARB)], and lisinopril [a brain-penetrant angiotensin-converting enzyme (ACE) inhibitor]; can be repurposed to treat CAA. At ~8 months of age, male and female Tg-SwDI mice (CAA model) began treatment with telmisartan (1 mg/kg/day) or lisinopril …

Bees And Bvocs: Characterization Of Scents From Flowers And What Bees Leave Behind, Chase Pagley, Dana Kraska, Maria Castellon

Undergraduate Student Symposium

Insect pollinators, such as bees, are an essential component to their ecosystem and surrounding plant life. Flowers emit odors, also known as biological volatile organic compounds (BVOCs), to attract bees to themselves during pollination. Additionally, when bees visit flowers, they are known to leave “scent marks” to communicate with other hive members which flowers to select or avoid for pollination. While BVOCs have been identified for many flowering species, there has not been extensive work analyzing odors from flowers that are popular with bee pollinators, such as Bidens alba (Spanish Needle). Furthermore, studies have not explored which odors are scent …

Burst Size Determination Of A Newly Discovered Yersinia Pestis Bacteriophage, Jewel Mousa

Undergraduate Student Symposium

The escalating global resistance to antibiotics has called for innovative alternatives to combat bacterial infections. Bacteriophages, viruses that can specifically target and destroy antibiotic-resistant bacteria, have emerged as a promising potential solution in phage therapy. This research focuses on a newly discovered phage capable of infecting Yersinia pestis, the causative agent of the bubonic plague, through the lytic cycle. In the lytic cycle, bacteriophages infect and replicate within bacterial cells, causing the cells to burst and release newly formed phages. Specifically, this study aims to characterize this recently discovered phage, utilizing experiments to determine its burst size, which indicates …

Characterization Of Exosomes From Melanoma Cells, Kishan Goli

Undergraduate Student Symposium

Melanoma is a specific type of skin cancer associated with the melanocytes developing into malignancy. Melanocytes produce a pigment that provides protection from the sun’s ultraviolet radiation. Melanocytes produce this pigment when ultraviolet radiation hits the skin, causing damage to the epidermis. When the epidermis is damaged, it triggers a signal to produce melanin to protect against ultraviolet radiation. However, too much exposure can cause DNA damage within the epidermis, especially within melanocytes, leading to the inhibition of regulated mitosis. Hence, non-regulated mitosis can lead to excessive melanocyte production, which may result in melanoma. Exosomes are vesicles generated by all …

Christian Monasticism And The Making Of Modern Medicine In London, Nicole Shaker

Undergraduate Student Symposium

Christian monasteries were the first formal healthcare settings in London. They defined doctors as Jesus-imitators, hospitals as inclusive shelters, and medicine as the holistic treatment of mental, spiritual, and physical maladies. Today, London’s medical students are taught to strive towards Christian values like empathy and patience and London’s model of free healthcare represents inclusivity and generosity. But because medicine has evolved away from faith, London’s healthcare ultimately displays a watered-down image of its roots in love-based monastic service. This paper will examine how three values of monastic medicine in London during the Late Middle Ages— agape love, hospitality, and holism— …

Comparing The Effects Of Invasive Waterhyacinth On Aquatic Communities, Maria José Gacharná Ferro, Colby Holbrook, Reginald Kempson Iii, Andrew Kuntz, Layla Lacelle, Claire Scobie, Indaya Byer

Undergraduate Student Symposium

Waterhyacinth is an invasive freshwater species that rapidly grows across water bodies, creating dense mats that disrupt local ecosystems. Our goal was to measure the impact of waterhyacinth on aquatic communities. We tested the hypotheses that waterhyacinth supported different fish and invertebrate species than native aquatic plants, used more dissolved oxygen (DO), and provided different levels of support to abundant invertebrates like amphipods. The fish communities under both plant groups were collected using a 1m2 throwtrap and a backpack electrofisher. This allowed for comparison between fish communities and method efficiency. We compared invertebrate community assemblages by collecting samples of roots …

Eating Disorders: A Public Health Perspective, Avisha Thota

Undergraduate Student Symposium

There are six primary eating disorders, including anorexia, bulimia, binge eating disorder (BED), avoidant restrictive food intake disorder, pica, and rumination disorder. The purpose of this project is to identify the underlying patterns between cultural taboos and/or low food insecurity (FI) and the likelihood of developing an eating disorder. It was hypothesized that if either cultural taboo about eating or low food insecurity is present, then the development of an eating disorder is more likely. A comprehensive literature review extracted keywords and reoccurring patterns from various primary and secondary sources. The hypothesis was partially supported, as the two factors have …

Evaluating Telmisartan's Impact On Metabolic Health And Cognitive Function In Mice Subjected To A High-Fat Diet, Julianna Bonetti, Ariana Hernandez, Iliana Uribe, Victoria Pulido-Correa, Chana Vogel, Nikhila Paleati, Natalia Noto

Undergraduate Student Symposium

A high-fat diet can induce metabolic syndrome, a group of risk factors for developing cardiovascular disease and diabetes. In turn, metabolic diseases increase the likelihood of developing neurodegenerative and neuropsychiatric disorders (e.g. dementia, anxiety, and depression). While telmisartan, an ARB (angiotensin II type 1 receptor blocker), is known to treat hypertension, it can also reduce weight gain, while improving dyslipidemia and glucose metabolism in male mice fed a high-fat diet. However, it is unknown whether telmisartan can reverse behavioral changes caused by a high-fat diet. This study assesses the effects of treatment with telmisartan on metabolic outcomes and cognitive-behavioral function, …

Exercise As A Natural Kappa Opioid Receptor To Treat Binge Drinking Withdrawal, Eleanor Wind, Iliana Uribe, Ariana Hernandez

Undergraduate Student Symposium

Binge drinking is a serious public health problem in the United States especially among college students. Clinical trials demonstrate positive results for the treatment of alcohol abuse with aerobic exercise. Research in animal models aims to answer questions regarding implementation across sexes and age groups by studying underlying neurobiological mechanisms such as kappa opioid receptor (KOR) activation. KOR antagonists have been shown to reduce anxiety and depressive symptoms associated with ethanol withdrawal. Chronic treadmill exercise reduces KOR binding and G-protein activation in rodents, suggesting exercise could have an effect on symptoms of ethanol withdrawal similar to KOR antagonists. Previous research …

Expanding Shelter Dog Research And Service To Encompass University Campus Communities, Lea Stephen, Richa Patel, Raquel Walton

Undergraduate Student Symposium

Many animal shelters are actively exploring social enrichment (SE) programs to alleviate animal stress and reduce residency times. SE invests in resources for focal animals (e.g. field trips, play groups, and/or augmented cages) to improve health, temperament, and adoption prospects. SE hinges on many factors, including strategic design and resource recruitment (e.g. human volunteers) to implement data-driven protocols. We propose that college students can help expand and refine SE efforts of campus-adjacent animal shelters, while meeting student needs for meaningful service and research opportunities. To demonstrate this, we completed diverse SE-related activities over the last two semesters using public data, …

Exploration Of Mdm2-Aurkb Regulatory Interaction: Implications For Cell Cycle Arrest And Cell Death In Lung Cancer, Akshara Sriram, Esha Surana

Undergraduate Student Symposium

Lung cancer is the most prevalent cause of cancer-related deaths worldwide, with a 5-year survival rate of 26.6% in the USA contributing to a higher mortality in comparison to other cancers. Among various abnormalities, MDM2 overexpression can positively influence the intracellular mechanisms and contribute to cancer progression through AURKB activation. Also, FOXO3A, a member of the Forkhead Box transcription factors linked to MDM2, serve as intermediates for various cellular mechanisms, including tumorigenesis, cell cycle progression, DNA damage, and cell death. Therefore, blocking MDM2 with specific inhibitors has become one of the promising strategies for the restoration of p53 mediated tumor …

Exploring The Genetic Elements Regarding The Early Onset Of Arthritis Due To Crohn's Disease, Vamsi Korisapati, Karam Asad

Undergraduate Student Symposium

Crohn’s disease is a rare inflammatory bowel disease that negatively impacts the lining of the digestive tract. Crohn’s disease increases the probability of early onset arthritis, both of which are commonly associated chronic conditions. An overactive immune response is the primary cause of inflammation in Crohn's disease, and this inflammation can damage not only the digestive tract but also other regions of the body such as the joints. However, patients who are diagnosed with arthritis are typically prescribed nonsteroidal anti-inflammatory drugs which are not recommended for patients with Crohn’s disease (ex. aspirin, naproxen, & celecoxib). On the other hand, disease-modifying …

Exploring The Therapeutic Potential Of Telmisartan Against High Fat Diet-Induced Nonalcoholic Fatty Liver Disease: A Dose- And Sex-Dependent Study In Mice, Nitisha Dundigalla, Ariana Hernandez, Victoria Pulido-Correa, Chana Vogel, Iliana Uribe, Shalet James, Eleanor Wind, Natalia Noto, Valeria Cohen, Julianna Bonetti

Undergraduate Student Symposium

Nonalcoholic fatty liver disease (NAFLD) is a condition where excess fat builds up in the liver, often developing in response to poor diet consumption and associated metabolic disturbances (obesity, Type II diabetes). Telmisartan, an Angiotensin II receptor blocker commonly used for treating hypertension, may hold therapeutic value against the adverse metabolic effects of a high fat (HF) diet, including NAFLD. This project explores whether the effects of Telmisartan are dose- and sex-dependent in obese, prediabetic mice. Male and female C57BL/6J mice were fed high-fat (HF) or low-fat (LF) diet starting at ~3 months old; diet was maintained for the remainder …

Data on this parasite’s prevalence in our local (South Florida) ecosystem is lacking, which could help inform both public health and conservation efforts. Our questions for this study include: a) how prevalent is this parasite locally? b) do avian species differ in infection rates? c) does parasite abundance differ between localities?

Thus far, tissues have been dissected from carcasses provided by partner conversation facilities, including two very common South Florida bird species: Green Herons (a large wetland-associated …

Red Dog Loess, A Peoria Equivalent, Last Glacial Desert Loess Of The White River Badlands, South Dakota, Usa, John Nichols, Corinne Renshaw, Lillie Suthers, Amanda Altree, Tava Boeckel, Ritika Vonguru

Undergraduate Student Symposium

Understanding how ecosystems in the Great Plains responded to droughts and prehistoric climate change is important for interpreting future climate disturbances and water resource planning. There is a correlation between glacial periods and atmospheric dust distribution, with significant dust deposition in the Great Plains during the Last Glacial Maximum, ~23,000 years ago (23ka). Continuous freezing and thawing events in the mid-continent led to erosion in the Great Plains, transporting a significant deposit of windblown dust, or loess, and an ecological collapse of the grassland ecosystems. This research aims to determine if the White River Badlands (WRB) region was the source …

Reducing Inoculum Effect By Modulating Growth Productivity Through The Superpathway Of Purine, Pyrimidine And Histidine Synthesis In Escherichia Coli, Ruth Thomas, Daniella M. Hernandez, Melissa Marzouk

Undergraduate Student Symposium

Antibiotic overuse has driven the evolution of multiple antibiotic-resistant bacteria that complicate infections that were once easily treatable. While mechanisms by which individual bacterium resist or tolerate antibiotics are well explored, less studied are the mechanisms by which populations of bacteria tolerate antibiotics as a collective. One such mechanism bacteria employ to tolerate antibiotic treatment as a collective is the inoculum effect (IE). We recently discovered that growth productivity, which describes the relationship between ATP production and growth rate, can account for IE for multiple antibiotics and pathogens. However, the underlying pathways for determining growth productivity have yet to be …

Relationships Between Emotion Regulation, Self-Directed Behaviors, And Student Learning Outcomes In Online Vs. In-Person College Courses, Sri Vaishnavi Konagalla

Undergraduate Student Symposium

Research examining student learning outcomes in online vs. in-person learning has shown varied results, with some studies showing more favorable outcomes in in-person courses and others showing no major differences between the two course types. Further exploration into additional factors influencing satisfaction and learning outcomes in both course formats highlights the relationships between self-directed learning behaviors (SDLBs), emotion regulation (ER), and quality of sleep with increased academic performance and course satisfaction. Previous research examining SLDBs and ER on student outcomes is limited to either online courses or in-person courses and does not compare the two. Therefore, the purpose of this …

Religiosity, Mental Health Help-Seeking Behaviors, And Treatment Utilization Among Muslim Populations In America, Aminah Asghar, Jenin Mannaa

Undergraduate Student Symposium

Despite the emphasis Islam gives to mental health practices including prayer and meditation, Muslim populations in the United States, on average, do not seek professional mental health services. Little research has been conducted on the relationship between religion and mental health help-seeking behaviors and treatment utilization among Muslims. This study aims to investigate the utilization of mental health services in Muslim populations. We hypothesize that Muslims with higher levels of religiosity will be less likely to seek professional mental health help or support.

Data was utilized from the National Epidemiologic Survey on Alcohol and Related Conditions III (NESARC-III). Mental health …

Undergraduate Student Symposium

Glioblastoma is an aggressive brain tumor that poses a formidable challenge in terms of treatment due to its infiltrative nature and lack of effective conventional therapies. The presence of treatment resistant glioblastoma stem cells (GSCs) is hypothesized to be responsible for tumor growth; therefore, successful elimination of GSCs is necessary to prevent post-therapy tumor recurrence and patient death. Resveratrol (RSV) is a natural polyphenolic stilbene found vastly in plant products, such as the skin of red grapes. RSV and its analogs are known for their antimicrobial, neuroprotective, antiaging, anti-inflammatory, cardioprotective, and blood-sugar lowering properties. A challenge of utilizing RSV in …

Spring-Mass Model Characteristics In Distance Runners Across A Competitive Season, Isabella Vargas-Blanchard, Riley Schemel, Alexis Arena

Undergraduate Student Symposium

The spring-mass model (SMM) explains the elastic bouncing nature of the lower limbs during running as the tendons store and release elastic energy. It is primarily used to explain sprinting and is less understood in distance runners. SMM is quantified by evaluating the asymmetries in landing-takeoff and rebound percents (%) determined from ground reaction forces (GRF). Faster runners have less asymmetrical landing-takeoff% and more asymmetrical rebound%. SMM asymmetries may be sensitive to longitudinal training. Therefore, we sought to document changes in elastic bouncing properties over a 7-week competitive season in distance runners. Thirteen university runners (age, 19.8±2.2 yrs; height, 1.74±0.10 …

The Effect Of Kras Mutation In Lung Cancers And Neuroblastomas, Lohita Sunkara, Jessica Mangila

Background: KRAS gene mutations are more common in long-term tobacco smokers with lung cancer than in non-smokers. The KRAS gene mutations in Lung Cancers typically indicate poor prognosis and resistance to several cancer treatments. Patients with KRAS Mutations were often shown to present resistance to certain drugs such as targeted chemotherapeutics, including EGFR inhibitors. Results: KRAS mutations in NSCLC are driver mutations, which are known to activate signaling pathways that promote aggressive tumor …

The Impacts Of Feeding And Swallowing On Infants And Toddlers With Hypoxic Ischemic Encephalopathy: A Scoping Review Of The Literature, Elenie Ortiz, Katheline Hernandez, Julie Fumero, Rachel Seganti

Undergraduate Student Symposium

Hypoxic ischemic encephalopathy (HIE) is when the brain is deprived of oxygen leading to brain damage. There are two stages- the acute phase and the latent phase. The acute phase is when an initial lack of oxygen to the brain occurs. The latent phase occurs when oxygenated blood flow resumes in the brain, this is known as reperfusion injury. Symptoms can present directly after birth, or later in a child’s development, during the early childhood years. It is one of the most common causes of neonatal encephalopathy. It is a prevalent source of morbidity and mortality for infants throughout the …

The Portrayal Of The Femme Fatale: The Evolution Of Gender Roles In The Depiction Of A Femme Fatale, Esperanza Barrios, Amanda Perez Romero

Undergraduate Student Symposium

When male authors describe the word ‘femme fatale’, it is always a synonym for a seductive woman who brings disaster to an unfortunate male hero. But, when a female author writes the story, the definition changes to women who become victims of patriarchy. In turn, they transform into unfeeling women who use their charms to survive in a world where they are viewed as subdued, mink, and consenting objects for a male’s pride and satisfaction. There are two femme fatales who although they struggled to obtain their happiness, kept striving forward and did not let any difficulty fracture their minds …
