Antibiotic resistance is a growing concern within the scientific community. With few new antibiotics being introduced and an increasing number of resistant microbes, routine bacterial infections are becoming more difficult to treat in clinics and hospitals. The purpose of this study is to compare the ability of two environmental isolates – Staphylococcus aureus (S. aureus) and Exiguobacterium undae (E. undae) to grow in solutions of increasing concentrations of tetracycline and ciprofloxacin. After the bacteria showed grow in the solutions, antibiotic susceptibility was tested by examining zones of inhibition on Trypticase Soy Agar (TSA) plates. Our results …
Effect Of Bisphenol-A On Neurodevelopment In Drosophila Melanogaster Larvae, Alexandra M. Streifel
Effect Of Bisphenol-A On Neurodevelopment In Drosophila Melanogaster Larvae, Alexandra M. Streifel
All College Thesis Program, 2016-2019
This paper examines the effects of the chemical preservative bisphenol-A on the developing nervous systems of Drosophila melanogaster, or fruit fly, larvae. This study examines the effects of bisphenol-A using both behavioral as well as morphological paradigms. It was determined that bisphenol-A significantly increased the amount of time larvae spent in seeking behavior, the number of peristaltic contractions, and the distance traveled in a linear fashion. In the morphological analysis, indications of increased dendritic area in experimental larvae existed, but there was not enough data to determine significance. For future research, it is recommended that more data be gathered to …

Concussions, Why They Go Unreported, Drake Matuska
Celebrating Scholarship & Creativity Day (2011-2017)
Introduction: In the world today, concussions are a major health risk in sports and many other physically demanding activities. Every day, we see former athletes who have experienced multiple concussions complain of cognitive impairment and memory loss. It is the risk every athlete takes when they participate in a sport they love; however, when an individual plays through a concussion that is when a line is crossed. People playing through a concussion lead to the foundation of this study, which is to find out why individuals play through their concussions, why they fail to report, and the core cognitive reasons. …

Cardiac Tissue Engineering: Using Induced Pluripotent Stem Cells To Repair Damaged Cardiac Tissue, Megan Lenz

Heart Disease is the number one cause of death in the United States and affects many individuals on a daily basis. The purpose of this research was to explore possible tissue regeneration therapies that aim to improve and recover function of damaged myocardial tissue commonly seen as a side-effect of chronic heart disease. Cardiac tissue engineering using induced pluripotent stem cell derived cardiomyocytes (iPSC-CMs) is a relatively new method that involves dedifferentiating cells from any tissue of the host into pluripotent stem cells. These cells are then guided to be differentiated into functioning myocardial cells that can be used to …
An Analysis Of Bacterial Contamination Of Chicken Eggs And Antimicrobial Resistance, Holly Spitzer
An Analysis Of Bacterial Contamination Of Chicken Eggs And Antimicrobial Resistance, Holly Spitzer
All College Thesis Program, 2016-2019
Chicken eggs are a major component of American diets, with an average yearly consumption of approximately 250 eggs per person (American Humane Society). While highly nutritious, eggs are also one of the leading causes of food poisoning and food borne illness in the United States. Eggs may become contaminated by a number of different types of bacteria during production, including Salmonella, a group of bacteria that, according to the CDC, causes more than 1.2 million cases of food borne illness in the United States every year. In an effort to decrease the frequency of bacterial contamination, many food producers …

Hypoplastic left heart syndrome (HLHS) is a rare congenital heart defect occurring in fewer than 0.5% of live births in the United States (Fruitman, 2000). It is characterized by a critically underdeveloped left ventricle with accompanying imperfections including septal defects, under-sized aorta, and underdeveloped bicuspid and aortic semilunar valves (Mayo Clinic Staff, 2012; CDC, 2013). HLHS is detectable on ultrasound at the end of the first trimester of pregnancy allowing for early diagnosis and potential treatment in utero. While a protocol involving three surgeries exists to treat the condition, there is no cure for HLHS. Even with treatment, many …
