Dehydration And Traumatic Brain Injury, Lauren Gray

Undergraduate Student Symposium

Boxers lose up to 15% of their body weight and on average 6.7% prior to weigh in. Boxers dehydrate to make the weight class and will rapidly rehydrate before fighting. During fights, boxers receive traumatic brain injuries. There is reason to believe that if boxers are not properly rehydrated the traumatic brain injuries could be exacerbated, however, this hypothesis had never been explored. This study aimed to determine the extent of fluid loss and traumatic brain injuries. This study utilized 48 mice. Half of the mice received dehydration followed by rehydration while the other half had normal fluid intake. Half …

Diabetes Progression: From Statistical Analysis To Mathematical Modeling, Sandeep Dronavalli

Undergraduate Student Symposium

Diabetes constitutes one of the leading neuroendocrine conditions with nearly 9.4 % of the US population showing symptoms of it. Noteworthy, type 2 diabetes (T2D) accounts for 90 to 95 % of all cases. It is a chronic disease, and the clinical manifestations include hyperglycemia (prolonged blood glucose levels above normal), hyperinsulinemia (excess levels of insulin circulating in the blood) along with insulin resistance. This presentation includes a statistical analysis based on a cohort of 440 individuals where both, demographic and laboratory measurements are included. Based on these results, a mathematical model accounting for the obtained associations is solved. It …

Exploring Alternative Binding Locations Of 5-Ht Antagonist Ketanserin In Microtubules; Implications For Future Research, Caleb Siguenza, Tatum Hedrick

Undergraduate Student Symposium

Recently, it’s been demonstrated that classic psychedelic action is mediated via intracellular mechanisms rather than action at membrane receptors. This intracellular action elicits neuroplastic effect. The conclusion is that these effects are due to activation of intracellular 5-HT2AR based on using ketanserin as a selective antagonist based on its selectivity to bind to the membrane 5-HT2A serotonin receptor. However, neuroplasticity is dependent upon multiple mechanisms and signaling cascades including the dynamics of neuronal microtubules. As the targets of ketanserin’s biological intracellular activity are not fully elucidated, here we investigate the binding potential of ketanserin to domains of the microtubule constituent …

How The Molecular Vibrations Of Water May Prevent Skin Cancer, Jarlynn Ramirez, Angelina Georg, Colette Costello, Mahi Desai, Sandeep Dronavalli

Undergraduate Student Symposium

Studies have shown that when DNA absorbs ultraviolet light it can become structurally damaged leading to a mutation and possibly skin cancer. However, exposing skin to sunlight rarely leads to a mutation. This indicates that after the ultraviolet light is absorbed by the DNA the energy from the light can either cause a structural change to the DNA (a mutation) or be dissipated in a way that does not damage the DNA. Absorption of ultraviolet light causes molecular vibrations in DNA and these vibrations are what likely leads to structural changes in the DNA. One way the structural changes could …

In Their Own Words: Collaborative Assessment Of Undergraduate Intellectual Curiosity, Amenia Farraj, Jaylynn Sylvain

Undergraduate Student Symposium

For the last decade, college enrollment across the U.S. has trended downward, which has been attributed to factors including increased college tuition and impacts of the pandemic (Welding, 2022). Others predict that digital technologies like AI will end academia as younger generations lean less into their intellectual curiosity (Marche, 2022). Yet, some universities like Nova Southeastern University have seen an increase in enrollment even while college enrollment generally declined by 7% between 2019 and 2022 (Welding, 2022). Much of these educational forecasts do not come from students but from older generations who sense a shift in how students learn. By …

Undergraduate Student Symposium

Approximately 1.5 billion people suffer from chronic pain, with 68 million people suffering in the U.S alone. Chronic pain is pain that persists longer than 12 weeks despite medication or treatment. Within the U.S. about 5.5 million cancer patients experience chronic pain. Around 20% of these pains have neuropathic origins and develop from radiation therapy. Halneuron, a new drug in development, seeks to provide pain relief to those suffering from chemotherapy-induced neuropathic pain. This drug includes Tetrodotoxin (TTX), a potent neurotoxin found in species of pufferfish. Our 3D-printed model displays the structural details of TTX as a pore blocker within …

Survivorship And Bleaching Prevalence Of Nursery-Grown Massive Stony Corals In Southeast Florida, Emma Horton

Undergraduate Student Symposium

Coral cover on Florida’s reefs has severely declined due to anthropogenic stressors. A major impact on corals is thermal bleaching, where corals expel their endosymbiotic microalgae, leaving them vulnerable to mortality. Some coral species are more resilient to thermal bleaching and thus may be prime candidates to support coral reef restoration. This study examines post-bleaching survivorship of massive stony coral species in Nova Southeastern University's offshore nursery to identify which species to include in future restoration efforts. In September 2022, 172 fragments (<3cm dia) from six massive species were secured on cement pucks and deployed to mid-water PVC trees in the nursery. Over a 14- month period, the survival and bleaching prevalence of each species were recorded during four monitoring time points. After 14 months in the nursery, total fragment survivorship was 80%, with Pseudodiploria strigosa experiencing the highest survival (100%) and Orbicella favelota experiencing the lowest (61%). Water temperature was …

Identification Of Genes Implicated In Low-Grade Gliomas And The Progression Into Higher Grade Gliomas Through Aberrant Dna Methylation, Mit Patel, Arun Jagarlamudi, Varun Toot

Undergraduate Student Symposium

DNA methylation is a critical epigenetic modification involving the addition of methyl groups to DNA as a regulatory mechanism; aberrant patterns contribute to various diseases. Low-grade gliomas (LGG) arise from aberrant cellular differentiation through altered gene expression of various genes, of which DNA methylation plays a crucial role. LGG’s are characterized as slow growing tumors from glial cells of the central nervous system (CNS). Grade IV gliomas or glioblastomas (GBM) are one of the most aggressive brain tumor types with a poor clinical prognosis and median survival of only 15 months. The purpose of this investigation is to analyze the …

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 …

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 …

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 …

Undergraduate Student Symposium

Representations play a key role in communicating concepts and phenomena in courses such as chemistry, biology, and biochemistry. While representations have the potential to help students develop conceptual understanding of a subject, integrating multiple ideas to interpret and use the representations can be challenging. For example, biochemistry students are faced with the unique challenge of having to combine their knowledge of both chemistry and biology to make sense of complex biological structures and processes. Using the Visual Literacy Framework proposed by Schönborn and Anderson, the objective of our study is to investigate the symbolism embedded within biochemistry representations and how …

Changes In Neuromuscular Function Across A Competitive Collegiate Cross-Country Season, Riley Schemel, Alexis Arena, Isabella Vargas-Blanchard

Undergraduate Student Symposium

Resistance training strengthens neural adaptations that aid in improving neuromuscular functions such as the rate of force development (RFD) and power execution during an explosive task like a countermovement jump (CMJ). Distance runners do not engage in heavy resistance training and the effects of endurance running on neuromuscular functions are less known but may provide crucial biomarkers for monitoring performance and injury. The purpose of this intervention study was to evaluate changes in neuromuscular function from 7 weeks of competitive distance running without heavy resistance training. Thirteen university runners (age, 19.8±2.2 yrs; height, 1.74±0.10 m; mass, 61.9±9.0 kg) performed 3 …

Antibiotic resistance represents a significant global health crisis, especially within hospitals, creating a necessity for the search for alternative therapeutic agents to combat drug-resistant pathogens. One source of treatment is phages specifically targeting G. rubripertincta, a gram-positive, aerobic actinomycete bacterium which has shown intrinsic resistance to some antibiotics. Furthermore, G. rubripertincta can cause endocarditis and CNS infections in immunocompromised individuals. Several phages such as Alyssamiracle, Fribs8, Genamy16, and NovaSharks, have been discovered that successfully target G. rubripertincta. The goal of this research is to determine the optimal infection temperature and the burst size of these phases. By growing …

Developing A Better Animal Model Of Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (Me/Cfs), Roberto Fileni, Amanda Lee, Medha Mageswaran

Undergraduate Student Symposium

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a rare but extremely debilitating disease characterized by severe fatigue, even after only mild exertion. In fact, ¼-⅓ of patients are house- or bedridden, underscoring the urgent need for effective treatment. Patients with ME/CFS display hypocortisolism, overactive serotonergic systems, and elevated TGF-β levels, suggesting that ME/CFS includes dysfunction of the endocrine, nervous, and immune systems. Current animal models of ME/CFS use immune activators but lack the complex multisystemic nature of the disease and bear a closer resemblance to depression than ME/CFS. One recent study showed that an adrenalectomy (ADX) better matched the characteristics seen …

Impaired Mitochondrial Ultrastructure In Peripheral Neurons Under Cholinergic Receptor Muscarinic 1 (Chrm1) Loss: Implications For Alzheimer's Disease And Sensory Neurodegeneration, Amrutha Venkat

Undergraduate Student Symposium

Cholinergic Receptor Muscarinic 1 (CHRM1) is a G protein-coupled receptor expressed in both the central and peripheral nervous systems (CNS and PNS). The degeneration of cholinergic neurons and cholinergic hypofunction are pathologies associated with Alzheimer's disease (AD). Our recent studies have demonstrated a severe loss (≥50% decrease compared to non-demented individuals) of CHRM1 protein levels in the postmortem temporal cortices, which is associated with poor survival in AD patients. Moreover, investigations utilizing an enriched cortical synaptosomal mitochondrial fraction from wild-type and Chrm1 knockout (Chrm1^-/-) mice have revealed that Chrm1 loss leads to altered supramolecular assembly of oxidative phosphorylation-associated …

Interactions Between Atp Production, Growth Rate, And Antibiotic Lethality Determine The Inoculum Effect In Β-Lactamase-Expression Escherichia Coli, Ariane Kalifa, Philopatier Ibrahim, Kielan Singh

Undergraduate Student Symposium

Antibiotic resistance is a global threat, claiming approximately five million lives annually and impacting nations worldwide. In the U.S.A., this issue is significant, with 2.8 million diagnosed cases leading to 35,000 deaths each year. One way that bacteria can resist antibiotic treatment is through the inoculum effect (IE). IE explains how the concentration of antibiotics required to kill a population of bacteria increases as a function of bacterial density. Recently it was found that increasing ATP production/growth rate decreases the strength of IE. However, we do not know if this relationship can predict IE in bacteria that express β-lactamases as …

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 …

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 …

Quantification Of Persistent Organic Pollutants In Northern Fur Seal (Callorhinus Ursinus) Vibrissae: A Novel Approach, Courtney White

Undergraduate Student Symposium

Persistent organic pollutants (POPs) are characterized by their biologically accumulative nature, toxicity to organisms, and persistence in the environment. The physical and chemical properties of these “forever chemicals” enhance their capacity for global transport, and the ocean serves as their ultimate sink. The Eastern Pacific stock of northern fur seals (Callorhinus ursinus) on the Pribilof Islands, Alaska, represents of 70% of the global breeding population but has been experiencing a discontinuous decline since 1980. A proposed contributing factor to this decline is contaminant exposure. This study developed a novel technique for analysis of POPs in keratinous tissue. A …

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 …
