Tools And Trends: An Analysis Of Maya Dental Modification, Channing M. Cook

Honors Undergraduate Theses

The ancient Maya practiced dental modification, intentionally filing, incising, and inlaying stones into the front teeth, potentially to display identity and status. The literature surrounding Maya dental modification tends to overlook mechanical aspects of the process, and many studies approach dental modification through limiting or destructive means. Optical microscopy presents an adaptable, cost-effective option for closer inquiry. Preliminary research suggests the process of dental modification leaves distinct patterns of tool use, depending on style, that can be identified through optical microscopy. The sample selected includes 25 incisors and canines from 14 Classic period Maya individuals from Altun Ha, representing 12 …

Investigating The Effects Of A Psychoplastogen On Depressive-Like Behaviors In Huntington Disease Model Mice, Kaleigh M. Hanley

Honors Undergraduate Theses

Huntington Disease (HD) is a neurodegenerative disorder caused by an expansion in the trinucleotide CAG repeat on exon 1 of the huntingtin gene. In HD one of the first symptoms is often depression. In cases where SSRIs fail, treatments for treatment-resistant depression often become a patient’s only option. These rigorous treatments, such as electroconvulsive therapy, are not suitable for this patient population as it can worsen motor symptoms. In order to search for potential alternatives, we queried whether depressive-like behavior could be reduced in Hu97/18 and Q175FDN HD mice by administering tabernanthalog, a non-hallucinogenic psychedelic analog. Our study is not …

Effect Of Metal Ions On The Reactive Oxygen Species Scavenging Capabilities Of Cerium Oxide For Biological Applications, Agastya Mittal

Honors Undergraduate Theses

Ceria nanoparticles' capabilities to defend cells against oxidative stress through superoxide dismutase activity are well-documented. Ceria nanoparticles demonstrate a ratio between 3⁺/4⁺ oxidative states on the surface of the particles to exhibit oxygen vacancies, a feature that allows these particles to scavenge Reactive Oxygen Species (ROS) in times of Oxidative Stress. Oxidative stress arises from many wounds in the body, such as wounds in the skin, and can have significant impacts on the health of an individual. Even when receiving treatment for the skin wound, ROS can circulate from around the wound, be generated from an imbalance …

Modified Equations Of Conformal Symplectic Exponential Time Differencing Methods, Taylore M. Keesler

Honors Undergraduate Theses

Planetary orbits, pendulums, and hurricanes are everyday examples of nonlinear systems, often studied using differential equations. However, their exact solutions can not always be computed, and thus, we use numerical methods to approximate their solutions. Certain methods are better suited to preserve special properties of the system like energy and geometry. Through previous numerical simulations, a conformal symplectic method proves more effective in this preservation. To understand why, we find the modified equation of a nonlinear system with damping, which is a differential equation for which the numerical solution is exact. Through backward error analysis, we obtain these modified equations, …

From Boredom To Purpose: How Self-Concept Can Affect Motivation In The Workplace, Norma I. Cintron

Honors Undergraduate Theses

The present experiment explored whether or not a positive self-concept influences how individuals manage boredom in the workplace. It was hypothesized that individuals with a positive self-concept would cope better with boredom and complete a dull task more accurately. However, these hypotheses were not confirmed, the study found no significant relationship between self-concept and boredom coping, nor between self-concept and task accuracy. In fact, individuals with higher self-concepts were slightly less accurate, though the difference was not statistically significant. Additionally, the study analyzed participants’ written responses to questions about handling boredom using Linguistic Inquiry and Word Count (LIWC) software. The …

Investigating The Role Of Prostasin In Angiogenesis: A Chorioallantoic Membrane Model Approach, Zaima Aline

Honors Undergraduate Theses

Prostasin, also known as PRSS8 or CAP1, is a glycosylphosphatidylinositol (GPI)-anchored extracellular serine protease involved in various physiological and pathophysiological processes. Prostasin expression is observed during key phases of trophoblast invasion and placental development, critical steps in embryo implantation in Rhesus monkeys. This suggests a role for prostasin in extracellular matrix remodeling and tissue invasion, both essential for a healthy pregnancy. Moreover, prostasin appears vital for development as studies in mice show that a germline knockout of the gene leads to significant placental defects and eventual embryonic death, highlighting its importance in vascular and structural development within the placenta.

Examining The Effect Of A High Fat Diet On The Expression Of Adipokines In A Murine Model Of Barrett's Esophagus, Saagar A. Shah

Honors Undergraduate Theses

Chronic acid reflux results in injury to the esophagus and the development of Barrett’s Esophagus (BE). BE elevates the lifetime risk for a patient to develop Esophageal Adenocarcinoma (EAC). Clinically, one of the main risk factors for BE and EAC is obesity, which alters the secretion of inflammatory cytokines by adipocytes, also referred to as adipokines. Conflicting reports have been made to the expression of adipokines and their receptors in the progression to esophageal cancer. Utilizing an inflammation-based mouse model for BE, we hypothesize that alterations in the expression of adipokines and their receptors favor an inflammatory environment associated with …
