Human Adaptation And Morphological Variation: Expanding Diversity In Anatomy Curriculum, Jordan Cass, Cooker Storm

Seaver College Research And Scholarly Achievement Symposium

Introduction: The recent upturn in our nation’s socio-political conversation has fueled interest in ensuring that college curricula is diverse and inclusive. Because human anatomy is ubiquitous across colleges, it may be a valuable avenue to purposefully incorporate topics of diversity in a way that positively impacts our socio-cultural relationships. Providing students with a scientific understanding of our visible differences may mitigate subconscious bias when we see others who have different features. Purpose: We investigated the biogeographical factors that contribute to the morphological variability of the face, hair, and body size; with the secondary aim of developing diverse and …

Endogenous Cftr Expression In Human Epithelial Cell Lines, Zithlaly Amezquita

Undergraduate Research Conference

CFTR (Cystic Fibrosis Transmembrane-conductance Regulator) is a plasma membrane protein that functions as a chloride ion channel on many epithelial cells. There are over 1000 mutations that affect the function of this protein; however, the most common mutation is DF508. CFTR mutations target many secretory organs like pancreas and lungs causing the genetic disease cystic fibrosis (CF), common among Caucasians of northern European origin. Detection of endogenous CFTR expression is possible by a difficult and costly immunoprecipitation method but not by the most used western blotting method. Therefore, the goal of this project was to detect the endogenous CFTR expression …

Ingredient Classification Using Food Ontology, Ricky Flores

UNO Student Research and Creative Activity Fair

A food label provides some of the most crucial information for a food product. The food label is a key resource for many health-conscious consumers for understanding ingredients. It is also vital for individuals to avoid food allergens or help patients follow dietary recommendations. While the food labels in the United States are regulated by the Food and Drug Administration (FDA) many labels contain additional information or statements that are not regulated. Moreover, the food label may be complex or contain terminology that the layperson may not understand. Evidence has indicated that consumers often find nutrition labels confusing, especially when …

Seizure Prediction In Epilepsy Patients, Gary Dean Cravens

NSU REACH and IPE Day

Purpose/Objective: Characterize rigorously the preictal period in epilepsy patients to improve the development of seizure prediction techniques. Background/Rationale: 30% of epilepsy patients are not well-controlled on medications and would benefit immensely from reliable seizure prediction. Methods/Methodology: Computational model consisting of in-silico Hodgkin-Huxley neurons arranged in a small-world topology using the Watts-Strogatz algorithm is used to generate synthetic electrocorticographic (ECoG) signals. ECoG data from 18 epilepsy patients is used to validate the model. Unsupervised machine learning is used with both patient and synthetic data to identify potential electrophysiologic biomarkers of the preictal period. Results/Findings: The model has shown states corresponding to …

Phage Hunters: The Discovery Of Two Novel Bacteriophages That Infect Gordonia Rubripertincta, Sarah Ballarin, Neel Balusa, Melissa Bell, Samia Caballero, Joshua Chan, Maria Farez, Ashley J. Guillen-Tapia, Nashrah Pierre-Louis, Victoria Polishuk, Bhavya Soni, Julie Torruellas Garcia, Katie E. Crump

Sea-Phages

Antibiotic resistance is a global healthcare concern because it poses a threat to effectively treating bacterial infections and the need for alternative therapeutics are urgently required. Phage therapy, which uses viruses to treat bacterial infections, is a promising alternative to conventional antibiotics. Phages have also been widely used in the food industry to prevent microbial growth on certain foods and are currently being explored as a method for bioremediation of oil spills and wastewater treatment. Although phages are ubiquitous in nature, many have yet to be discovered. Through the SEA-PHAGES (Science Education Alliance-Phage Hunters Advancing Genomics and Evolutionary Science) program …

Thermal Tolerances Of The Invasive Macrophyte Hydrilla Verticillata, Joshua Williams

Graduate Research Showcase

Invasive species often rapidly spread due to their ability to adapt to a wide range of habitats they can occupy and lack of competition. Hydrilla verticillata is an invasive aquatic macrophyte that has spread across the United States due to human activities. Like many aquatic plants, Hydrilla has the ability to reproduce through fragmentation of the mother plant. In this method, Hydrilla fragments are then dispersed by water current to other areas where they can settle and grow. To date, little is known about the abiotic conditions that may restrict the spread of invasive Hydrilla. However, compared to other macrophytes …

Accelerometry Reveals Hidden Variation In The Movement Response Of Timber Rattlesnakes (Crotalus Horridus) To Roadways, Anna F. Tipton, Morgan L. Thompson, Dominic L. Desantis

Graduate Research Showcase

Roadways are among the most widespread and disruptive anthropogenic land use features that influence the behavior and movement of wildlife. Negative impacts including vehicle-induced mortality, habitat destruction and fragmentation, and creating barriers to movement have been well documented across taxa, but the fine scale behavioral impact of roadways on smaller, cryptic species has yet to be directly examined. Using a novel integration of emerging spatial analyses and tri-axial accelerometry, we quantified spatial and temporal aspects of movement and space use in order to investigate the coarse and fine scale influence of roadways on the movement patterns of Timber Rattlesnakes (Crotalus …

Mapping Fetch And Diel Movements Of Silver Carp Hypophthalmichthys Molitrix Within Kentucky Lake And Lake Barkley With Gis, Levi Umland

Scholars Week

Title: Mapping Silver Carp movements, relative exposure, and fetch within inland reservoirs using Geographic Information Systems.

Author: Levi G Umland

Invasive species across our country have continued to threaten our native species, compete for habitat via interspecific competition, and have caused economic impacts. Silver Carp (Hypophthalmichthys molitrix), commonly referred to as Asian Carp, have remained in the invasive species spotlight throughout the southern and mid-western states as they have continued to spread. Silver Carp have successfully spread through our rivers and reservoirs, but little is known about Silver Carp movement rates/behavior within reservoirs due to their lower abundance within …

Niche Partitioning And Utilization Of Different Nitrogen Sources By Marine Cyanobacteria Synechococcus, Angel Bui, Anne W. Thompson

McNair Symposium

The Cyanobacterium Synechococcus plays a major role in the ocean’s biochemical processes and is responsible for a significant amount of primary production, especially around coastal areas. Synechococcus has a wide geographical distribution that includes both polar and high-nutrient waters. Within the genus, there are defined subpopulations that are ecologically distinct that allow them to niche partition the dynamic oceans. To further explore niche partitioning of Synechococcus, this project combines a bioinformatic and culture-based approach. I examined data along the North Pacific Subtropical Front (NSPF) to analyze the community structure. This analysis demonstrated that a particular ecotype identified as clade II …

Understanding The Metabolic Regulation Of Trained Immunity By Palmitic Acid, Khaleda Aqaei, Brooke A. Napier

McNair Symposium

Sepsis is an inflammatory disease that occurs when the body’s response to an infection becomes dysregulated, and infection-fighting processes of the body damage tissues via inflammation, resulting in organ failure and death. Currently, the role for diet in regulating sepsis susceptibility and severity is not fully understood. The Western Diet (WD), the most prevalent diet worldwide, is high in saturated fatty acids (SFAs) and sucrose, and low in fiber. Previously, we have used a lipopolysaccharide (LPS)-induced sepsis mouse model to show that mice fed a Western Diet (WD) or a diet enriched only in SFAs (Ketogenic Diet; KD), experience increased …

Hybrid-Lipid Coated Silver Nanoparticles As An Antimicrobial, Alexandria Murphy, Marilyn R. Mackiewicz, Michael S. Bartlett

McNair Symposium

Silver has been known to be an antimicrobial for hundreds of years, but wasn’t thought to be useful in the medical field until the 1960’s. In more recent years people have been designing different methods of synthesis for silver nanoparticles, yet none of these methods prevent the oxidized silver (Ag+), which is toxic. As the use of silver nano materials for antimicrobial activity has expanded there has been an increase in interest in the medical field, and how silver nanoparticles can be used as an antimicrobial without having toxic effects. While there is a large availability of silver nanoparticles (AgNp’s) …

Cd40l And Tnf-Alpha Levels After Traumatic Injury, Queen Revollido, Martin Schreiber

McNair Symposium

The biomarkers CD40 ligand and TNF-alpha are proteins that exhibit proinflammatory and prothrombotic effects. A small clinical study has shown that soluble CD40 ligand may have a role in early coagulopathy and inflammatory complications in severely injured patients. It is known that a CD40 ligand increases the production of cytokines such as TNF-alpha, thus, the current study aims to investigate the kinetics of these biomarkers and the extent of upregulation after traumatic injury. Frozen samples collected from baseline, 8, 24, and 48 hours after admission will be used. CD40 ligand and TNF-alpha levels will be quantified using Luminex that will …

The Effect Of Apremilast On Circadian Rhythm In The Ventral Tegmental Area, Courtney Ledford, Angela Ozburn

McNair Symposium

Chronic binge drinking negatively impacts society and is a leading cause of preventable deaths. The purpose of the experiment is to determine if regulation of circadian rhythms in the ventral tegmental area (VTA) will contribute to less ethanol consumption. The VTA plays a major role in addiction. A simple genetic animal model examines iHDID-1 mice and their binge-like drinking intake. The mice undergo Drinking in the Dark (DID) for 6 weeks prior to administration of apremilast or saline treatment at weeks 7 and 8. The mice are exposed to DID and sacrificed at two separate time points (ZT 3 and …

Efficacy Of Curcumin In Asthma: A Systematic Review And Meta Analysis, Tabitha Grow, Adam Sadowski

McNair Symposium

Over 23 million people are affected by asthma in the United States and 262 million individuals globally. Asthma, if poorly controlled, is associated with significant morbidity as well as increased risk for mortality. Asthma involves several complex inflammatory pathways and processes including an increase in immune cell activation. Curcumin, the active constituent found in turmeric, has been studied in numerous in-vivo and in-vitro studies to generate anti-inflammatory effects in pulmonary diseases and, more recently, an increase in clinical data has become available. Since the most recent review assessing the role of curcumin in pulmonary disorders, additional clinical trials have been …

Using Bioenergetics To Model The Effects Of Climate Change On Bluntnose Minnows Pimephales Notatus In A Western Kentucky Stream, Christian Slone, Christian Slone

Student Scholarship & Creative Works

Bioenergetics considers a variety of factors like consumption, excretion, and metabolism to quantify the energy use of an organism. A common use of bioenergetics modeling is to help solve fish stock problems. This project looks to develop a bioenergetics model for Bluntnose Minnows Pimephales notatus to help predict effects of climate change on the biodiversity of western Kentucky streams. We used R and NetLogo to create an agent-based bioenergetics model to simulate the size distribution of Bluntnose Minnows under various temperature regimes. Bluntnose Minnow metabolism increases, and consumption decreases with an increase in water temperature. Fish growth seems to be …

Stream Sediment Monitoring In Morehead Kentucky, Kristopher Krolikowski, Jen O'Keefe

2021 Celebration of Student Scholarship - Oral Presentations

Sediment loads in stream systems play a big role in how overall runoff behaves. Streams naturally transport sediment at various ratios depending on precipitation. When vegetation is removed in upstream environments, sediment loads on streams increase. Sudden increases of sediments in streams can cause many issues, such as flooding or stream re-direction. In Morehead, KY, large-scale logging operations on the ridge above Knapp Avenue and on the ridge above the north end of Allen Avenue have caused increased sediment load in a small stream called Oxley Branch. This stream flows south parallel to Knapp Avenue and along the eastern property …
