The Effects Of Family Structure Stability And Transitions On Young Children’S Sleep: Evidence From The Millennium Cohort Study, Shanea Foster, Mikaela Dufur
The Effects Of Family Structure Stability And Transitions On Young Children’S Sleep: Evidence From The Millennium Cohort Study, Shanea Foster, Mikaela Dufur
Journal of Undergraduate Research
Over the years, family structure has become a topic of great interest in the social science community, particularly as it pertains to family structure type (i.e. biological parents, cohabiting, stepparents, etc.) (Dufur et al., 2010). More recently, family stability has come under scrutiny. Family structure has the potential to change over time, whether it be experiencing a disruption (going from married parents to single) or reconstitution (going from single parent to married or having a partner). We find interest in family structure changes over time as it pertains to its potential effects on their children’s sleeping behavior (Wong, Brower & …
Ab Blood Type And Its Genetic Relationship To Alzheimer’S Disease, Mark Wadsworth, John S. K. Kauwe
Ab Blood Type And Its Genetic Relationship To Alzheimer’S Disease, Mark Wadsworth, John S. K. Kauwe
Journal of Undergraduate Research
Alzheimer’s Disease (AD) is a debilitating disease that has increased the hardship of many lives. Many people above the age of 65 have been diagnosed with this genetically complex disease, which financially and emotionally burdens those diagnosed and their families. Earlier this year a study was released that found, using a dataset of individuals that have had strokes, that individuals with AB blood type are more at risk of developing cognitive impairment[1]. This study however was not looking at the genetics of AD. My objective in performing this study was to see if there is a genetic association between Alzheimer’s …

Determining If C-Fos Protects Β-Cells From Apoptosis, Kyle Kener, Jeffery Tessem
Journal of Undergraduate Research
Diabetes, a disease characterized by the inability of the body to maintain a normal blood glucose level, continues to affect the lives of many. In both Type I and Type II diabetes, eventual β-cell destruction results in decreased β-cell mass. Regeneration of functional β-cells and protection of such, could help reverse the effects of this disease and could possibly lead to a cure. Many studies have been done to increase functioning β-cell mass, but protecting regenerated β-cells from further apoptotic insults could greatly increase the effectiveness of β-cell transplants and other future treatments of the disease.

Discovery And Characterization Of Bacteriophage To Control Mrsa, Jacob B. Hatch, Bradford Berges
Journal of Undergraduate Research
About 20% of humans are carriers of Staphylococcus aureus (SA). There were an estimated 11,000 deaths in the United States in 2005 attributed to SA, with the majority caused by MRSA (Methicillin Resistant Staphylococcus Aureus) isolates [1]. Many MRSA isolates have developed resistance to all but one antibiotic drug: vancomycin. However, other bacteria have developed resistance to vancomycin, suggesting that in time MRSA will likewise become non-responsive to this last available drug and MRSA infections will be untreatable. This project looks to find an alternate method of MRSA treatment. Bacteriophage (phage) are viruses that infect bacterial cells in order …

It is estimated that 5.2 million Americans have Alzheimer’s disease. It is currently the 6th leading cause of death in America, killing around 500,000 seniors every year. A 68% increase of death from Alzheimer’s disease was observed from the year 2000 to 2010. These numbers are expected to continue climbing.
The Role Of Pas Kinase And The Gut Microbiome In Metabolism And Diabetes Onset In Mice, Andrew Rees, Laura Bridgewater
The Role Of Pas Kinase And The Gut Microbiome In Metabolism And Diabetes Onset In Mice, Andrew Rees, Laura Bridgewater
Journal of Undergraduate Research
Diabetes and obesity are among the most prevalent health concerns in the modern world. However, prevention of their onset and control of their symptoms are still largely limited by our understanding of how these diseases arise. Recent research has indicated that the composition of the gut microbiome is one of the important factors in development of these diseases (5). However, current thinking is not definitive on the relative importance of genetic factors, diet and the gut microbiome, among other factors (5,6). PAS Kinase provided a model through which we could compare the relative affects of genetics, gut microbiome and diet …

The Role Of Cdk5r1 In Β-¬Cell Survival From Apoptosis, Amanda Hobson, Jeffrey Tessem
Journal of Undergraduate Research
Type 1 and Type 2 diabetes are classified as a decrease in functional ß-cell mass, which results in impaired blood glucose regulation. Functional ß-cell mass is defined as the glucose stimulated insulin secretion rate multiplied by the total cellular mass which is determined by the proliferation and cell death rates. Though ß-cell mass proliferation rates generally decrease by adolescence, obesity and pregnancy have been shown to be times of significant ß-cell proliferation (1). This implies that the inherent molecular pathways necessary for ß-cell proliferation are present, but highly regulated. Discovering the molecular pathway of ß-cell proliferation could lead to diabetes …
Anatomical Variation Of The Ulnar Collateral Ligament And Implications For Joing Stability And Surgical Rehabilitation, Jakob Gamboa, Dr. Jonathan Wisco
Anatomical Variation Of The Ulnar Collateral Ligament And Implications For Joing Stability And Surgical Rehabilitation, Jakob Gamboa, Dr. Jonathan Wisco
Journal of Undergraduate Research
In 1974, the first ulnar collateral ligament reconstructive surgery was performed on Los Angeles Dodgers’ pitcher, Tommy John. The damaged ligament of the medial elbow was repaired with tendons from the pitcher’s body. Since then, the surgery has been colloquially termed “Tommy John’s Surgery”, and the alarming increase of the rates of the procedure has now become a concern, being recently called an “epidemic” by the American Sports Medicine Institute1. The procedure possesses risk of complications, and can lead to shortened careers, decreased performance over time2, and can carry a heavy financial toll on individuals and …
Testing The Effect Of Antioxidants On The Pathogenesis Of Alzheimer’S Disease Through The Rage/Nf-Kb Inflammatory Pathway, Harrison Snyder, Jonathan Wisco
Testing The Effect Of Antioxidants On The Pathogenesis Of Alzheimer’S Disease Through The Rage/Nf-Kb Inflammatory Pathway, Harrison Snyder, Jonathan Wisco
Journal of Undergraduate Research
The Receptor for Advanced Glycation Endproducts (RAGE) is known to have a role in inflammatory processes. When produced in excess it induces oxidative stress by activating a number of ligand enzymes, resulting in the generation of excessive cytosolic reactive oxidant species. This oxidative stress then stimulates Nuclear Factor Kappa-B (NF-kB), which regulates immune response and inflammation. When RAGE is incorrectly regulated, inflammation occurs in otherwise healthy tissue, a process implicated in neurodegenerative disorders like Alzheimer’s disease. RAGE is found throughout the body and is seen in greater concentration in inflamed tissues; it has also been found in the brain tissue …

I was interested in trying to validate the findings of the publication by Medway et al. concerning the SNP rs199768005 using data from the Cache Country data set. Unfortunately, of the 4703 people from our data set, only 10 were carriers. Using R statistical analysis, I found that the p-value for this SNP with an association to protect for Alzheimer’s Disease (AD) was not significant. It was similarly not significant in its association with Any AD. I also ran other models to include for factors such as education or age in conjunction with this SNP and its association with AD …

Ligament Microstructure Analysis, Michael Gillespie, Jonathan Wisco
Journal of Undergraduate Research
Due to the relatively poor fiber contrast of tendons in comparison with muscles, the anatomical, and therefore, functional relationship of muscle attachments to bones via tendons has not been well mapped. We were interested in mapping the 3D gross anatomical structure of tendons using a MicroScribe 3D digitizer (GoMeasure3D, Amherst, VA), with the goal to compare fibrous architecture between tendons of various types of muscles and muscle classes. We developed a stain made of blue dye and powdered sugar to increase fiber visibility, thus allowing for 3D digitization. This technique was applied to human cadaveric calcaneal tendon and quadriceps tendon.

Analyzing Structural Differences In Quadriceps Femoris Tendon Fibers Using Microscribe Technology, Nathaniel Hainsworth, Jon Wisco
Journal of Undergraduate Research
Not all tendons and ligaments are created equally. Many have different structural characteristics based on functionality or need for stability. This turns out to be true even between different portions of the same tendon. This project’s purpose was to analyze and compare structural differences between tendon fibers of the patellar portion and quadriceps portion of the quadriceps femoris tendon. We hypothesized that there are significant structural differences between these two portions because they act very different biomechanically, as well as different in the amount of tension/strain put on each portion. We mapped individual tendon fibers of both portions using MicroScribe …

The floor of the oral cavity is covered by a mucosal layer to protect underlying structures against the digestive events of the mouth. Ducts of the salivary glands open into this mucosa along the lingual frenulum. The lingual nerve from the mandibular division of the trigeminal nerve immediately begins to branch after passing through the foramen ovale, and continues its descent medial to the inferior alveolar nerve. Just superior to the angle of the mandible, the nerve turns anteriorly 90 degrees and continues a lateral to medial path to the anterior of the mouth. It crosses the submandibular salivary duct …

Targeting Superoxide Dismutase-¬1 In Cancer, Laura Oh, Josh Andersen
Journal of Undergraduate Research
SOD1 is overexpressed in many cancers such as lung adenocarcinoma, non- small-cell lung cancer, and 70% of primary breast cancers. Traditionally, SOD1 is known as an antioxidant in the human body, but only 1% of SOD1 expressed in cells is necessary to keep superoxide radicals below cytotoxic levels, suggesting that SOD1 may have undiscovered functions. One of the known trademarks of cancer is the Warburg Effect defined by up-regulated glycolysis and down- regulated respiration. It is thought that this unique mode of metabolism promotes cancer cell growth. A recent study demonstrated that SOD1 functions to repress respiration through the casein …

Preterm birth is the leading cause of death in children under the age of 51 and is defined by the Centers for Disease Control as birth before 37 weeks gestation.2 It is estimated that 15 million babies are born premature annually and that PTB kills nearly 1 million babies every year. Currently, accurate detection of PTB risk isn’t possible and extrauterine treatments and interventions are insufficient.

Once the leading cause of death in the United States, tuberculosis still burdens the world as the second deadliest infectious disease worldwide, latently infecting one-third of the world population and causing 1.5 million deaths in 2013 [1]. Tuberculosis is particularly lethal largely because the pathogen Mycobacterium tuberculosis has several characteristics that make detecting, treating, and studying the disease unusually hard. Among these traits, M. tuberculosis has a complex cell wall that limits the effect of many antibiotics and makes genetic manipulation of the bacterium, a necessity for effective research, nearly impossible through conventional transformation techniques [2]. Recently, Howard Hughes Medical …
The Role Of Wnt Secretion From Neural Crest Cells In Proper Craniofacial Development, Bradley Haynes, Stark Michael
The Role Of Wnt Secretion From Neural Crest Cells In Proper Craniofacial Development, Bradley Haynes, Stark Michael
Journal of Undergraduate Research
Both Wnt signaling and neural crest cells (NCCs) have a well-established role in the development of facial bones and cartilage. Wnt signaling is known to be required for neural crest cell formation; however, Wnt expression originating from the neural crest after their specification by Wnt1 has not been carefully explored. The purpose of our study is to investigate the role of Wnt secretion from NCCs in craniofacial development. Our hypothesis is that loss of Wnt secretion from NCCs will lead to improper craniofacial development and contribute to facial structure abnormalities.

Assessment Of Biodiversity On Mount Timpanogos With A Focus On Flies, Diptera: Agromyzidae, Samantha Smith, Dr. Riley Nelson
Journal of Undergraduate Research
Mount Timpanogos, with an elevation of 3,582 meters, is home to an amazing array of insect species. Through much previous effort, many have studied the insects found in American Fork Canyon leading up to Mount Timpanogos. They have still barely scratched the surface of the abundant biodiversity on the mountain. Varied temperature regimes can cause changes in insects’ life cycle and the length of their feeding period, making the collections at different elevations of Mount Timpanogos during different years of particularly great value (Petitt et al 1991). Thus the value of collections along Mount Timpanogos is two-fold; both to study …

One of the primary focuses of much addiction research involves finding methods to alleviate methamphetamine (METH) addiction. METH is one of the most widely used illicit drugs in the United States. Estimates by the National Institute on Drug Abuse Statistics are that 5.5% of all adults ages 26 and above have at tried METH at least one time. Given its high addictive potential, the chance for entering damaging addiction cycles among these individuals is very high, and can have great societal and economic consequences in addition to physical and mental problems on the individual level. While the need for better …

Alzheimer’s disease (AD) is a chronic neurodegenerative disorder that occurs predominantly later in life and represents the fourth most common cause of death in the developed world. Given the absence of curative treatment, discovering the factors related to the development of AD and the conversion from mild cognitive impairment (MCI) to AD is one of the most urgent medical mysteries affecting the aging population. The search for the identification of genes contributing to AD led to the identification of 695 candidate genes of which a surprising number are directly involved in lipid metabolism at the level of transport, synthesis, storage, …

Journal of Undergraduate Research
Alzheimer’s disease is one of the top 10 causes of death in the world and the 6th leading cause of death in the United States, with 5.5 million people diagnosed with the disease. Alzheimer’s cannot be cured, prevented or slowed. Most research with Alzheimer’s disease has been done on SNPs that have a relatively high frequency in the population this has helped facilitate researchers in finding a broad genetic pathway in the development of Alzheimer’s disease (Naj et al. 2011; Harold et al. 2009). Our research will focus on a very rare SNP, with a much lower frequency than previously …

Journal of Undergraduate Research
Vascular dementia (VaD) is a neurodegenerative disease caused by atherosclerosis, or inadequate blood flow to the brain as a result of the build-up of fat deposits, dead cells, or other cell debris on the inside of arteries. It shortens the lifespan of those affected, and severely impairs their quality of life. VaD is the second most common form of dementia, after Alzheimer’s disease, accounting for 20-30% of dementia cases. Thus far the risk factors that have been determined are non-specific to the brain: high blood pressure, high cholesterol, and high blood sugar (Roman et. al 2003). There has not been …

Assembling Benchmark Datasets For Machine Learning Classification, Parker Hollingsworth, Stephen Piccolo
Journal of Undergraduate Research
Machine learning classification is a type of artificial intelligence that learns from data and makes predictions. There are many different algorithms that can be used to develop predictive models for machine learning. Generally the algorithm looks for patterns in the data and uses those patterns to make predictions on an additional data set. This type of artificial intelligence is being used increasingly in the biomedical community to predict disease diagnosis and prognosis. Although machine learning has shown to provide promising results, it is far from perfect. The accuracy of the predictive model often depends on arbitrary decisions made by researchers. …

Investigation Of Visual Systems In A New Species Of Firefly, Yelena Pacheco, Dr. Seth Bybee
Journal of Undergraduate Research
Fireflies are well known for their bioluminescent flashes causing them to be a particular group of interest concerning insect vision research. Their flashes are used for both sexual communication and as an aposematic warning to predators. Bioluminescent fireflies are known to use either a yellow-green flash or a yellow-orange flash to communicate between sexes in order to find a mate. There have been many studies concerning flash patterns’ role in sexual communication among fireflies; however, the understanding of firefly vision as a whole allows for many more untouched research possibilities. As a member of the Bybee lab I had the …
Single Nucleotide Polymorphisms And Accelerated Telomere Shortening, Rebecca Winner, Dr. Brent Nielsen
Single Nucleotide Polymorphisms And Accelerated Telomere Shortening, Rebecca Winner, Dr. Brent Nielsen
Journal of Undergraduate Research
Telomeres are protective deoxyribonucleic acid caps on the ends of chromosomes which help prevent the chromosome itself from shortening during replication. As a person ages, normal telomere shortening occurs due to chromosome replication. However, accelerated telomere shortening is abnormal and has been linked to several factors such as disease, depression, and anxiety.
This project aims to determine if underlying genetic factors that contribute to increased incidence of depression will produce accelerated telomere shortening as seen in subjects with a history of depression. SNP’s in genes that code for 5-HTT, a serotonin receptor, and DRD2, a dopamine receptor, have been shown …
