Comparison Of Cardiac Muscle Between Male And Female Rats With Exercise And Aging: Analyzing Vitals, Gdnf Expression, Ngf Expression, Rna Expression, Sympathetic Innervation, Parasympathetic Innervation, And Sensory Innervation, Katelyn Kurrie

Honors Theses

The direction of my research-based thesis answers the question of how exercise affects the cardiovascular system with aging in male and female rats. My study would highlight the important differences of the cardiovascular system of both sexes which could lead to sex-specific insight on the cardiovascular disease epidemic which prevails as the most common cause of death in the United States. The studies completed will test the hypothesis: neurotrophic factor will be higher in females than males due to the higher presence of estrogen in females. The trophic factor is predicted to increase in both males and females with regular …

An Examination Of Barriers And Determinates Impacting The Healthcare Of Kalamazoo County's Transgender And Non-Binary Young Adult Population, Tyler Signorella

Honors Theses

Historically non-binary and transgender individuals have faced and continue to face a unique set of obstacles and challenges in seeking and receiving general healthcare. Within the US this is well documented on a national level. In this exploratory study we will seek to understand the experience of young adults in Kalamazoo County comparing their perspectives to the already established pool of information. This will be accomplished through surveying emergent adults identifying as either transgender or gender non-binary within Kalamazoo County and then synthesizing this data into an analyzable collective format.

Incorporating Worksheets To Enhance Active Learning In A Laboratory Course, Zakiya S. Kelley

STEM Instructional Graduate Teaching Assistant Posters

Study Goals:

To create worksheets that would aid the students in properly completing the required experiments and challenge them to do more than just follow the instructions. Each week there were often multiple experiments to be completed and pre-made samples to be observed within the class period. By providing the worksheet, I ensured the students completed all tasks and comprehended the covered material before class ended.

Objectives:

• To improve student participation and information retention when completing laboratory experiments in the classroom
• To emphasize key points of the topic being explored

Changes In Gene Expression Profiles In Müller Glia Following Exposure To An Α7 Nicotinic Acetylcholine Receptor Agonist, Megan L. Stanchfield

Masters Theses

Previous studies from this lab have determined that dedifferentiation of Müller glia (MG) occurs after application of an α7 nicotinic acetylcholine receptor agonist, PNU-282987 (PNU), to retinal pigment epithelial (RPE) cells in adult rodents. This study was designed to explore the role of the HB-EGF/Ascl1/Lin28a signaling pathway in MG dedifferentiation to retinal progenitor cells. RNAseq was performed on MG following contact with RPE-J cells treated with PNU-282987. Up- or down-regulated genes were compared with published literature of MG dedifferentiation that occurs in lower vertebrate regeneration or with transcript profiles during early mammalian development. Between 8-12 hours, up-regulation was observed in …

High-Efficiency Transformation Of Yeast By Electroporation, Lilly Ruell

Honors Theses

This paper analyzes and optimizes efficiency in the yeast transformation protocol using electroporation. Three variables were tested for optimization, they are the following: DNA concentration, cell density and electroporation voltage. Further verification of transformation was done through the analyzation of HPLC data to ensure protein production. The results conclude that DNA concentration was the most important dependent variable for transformation efficiency. A voltage of 2000V is the optimal condition to achieve efficient yeast transformation. Cell density had no observational difference in transformation efficiency at the range of DNA concentration necessary for research use. Improving this efficiency of the yeast transformations …

Organized Caudal Photoreceptors In The Medicinal Leech, Baylee Bancroft

Honors Theses

Visual systems are essential to an organism’s survival. There are a wide range of photosensory organs across the animal kingdom, varying by means of structure, complexity, and the way in which they transduce information. Regardless of variation, visual systems provide the organism with information regarding external stimuli based on how light interacts with surrounding matter. The medicinal leech, Hirudo verbana, is one of the many important model organisms of neurobiology as this segmented annelid possesses a relatively simple nervous system and a rudimentary visual system. The leech also exhibits a restricted range of quantifiable overt behaviors and is capable of …

Glut5 And Fructose Metabolism Inhibition In A Simulated Small Intestine Environment, Isabella Trainor

Honors Theses

This thesis describes an experiment that was designed in order to obtain information that could be useful for treating individuals with HFI. The author hypothesized that MSNBA would inhibit GLUT5 and fructose metabolism in the small intestine. The final experimental design involves exposing a small intestine cell line to fructose and MSNBA. The cell line would be exposed to MSNBA over the course of three different periods, and data was intended to be obtained using western blotting and a fructose assay kit. Although the final experimental design project was not fully carried out due to circumstances surrounding COVID-19, a plausible …

Understanding Stem Instructors’ Experiences With And Perceptions Of Deaf And Hard Of Hearing Students: The First Step Towards Increasing Access And Inclusivity, Makayla Long

Honors Theses

Through an anonymous survey we analyzed Western Michigan University (WMU) STEM instructors’ experience with and understanding of teaching and interacting with Deaf and Hard of Hearing (HoH) students. The goal of this study was to capture the experiences of WMU STEM instructors and the resources available to them given their direct impact on Deaf/HoH students’ ability to succeed and receive a post-secondary education. The findings of this study support the claim that instructors are not well supported or aware of the needs of Deaf/HoH students, and do not have access to adequate resources to resolve the issue.

The first steps …

Gender And Socioeconomic Disparities In Iatrogenic In-Hospital Torsades De Points, Bradley Reinoehl

Honors Theses

It has been well established for decades that women are at increased risk for torsades de pointes (TdP). Additionally, it has been well documented that patients of lower socioeconomic status (SES) tend to have inferior health outcomes compared to other patient populations. In this study we investigate the incidence of iatrogenic in-hospital TdP among these two demographic groups. Iatrogenic in-hospital TdP is a complex combination of medical issues and including danger from QT prolonging medications. In theory, a combination of identifiable, demographic risk factors coupled with specific clinical settings could be used to identify patients at high risk for iatrogenic …
