Computational Design And Molecular Modeling Of Morphine Derivatives For Preferential Binding In Inflamed Tissue, Makena Augenstein, Nayiri Alexander, Matthew Gartner

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The opioid epidemic has impacted over 10 million Americans in 2019. Opioids, like morphine, bind non-selectively in both peripheral tissue, leading to effective pain relief, and central tissue, resulting in dangerous side effects and addiction. The inflamed conditions of injured tissues have a lower pH (pH = 6–6.5) environment than healthy tissue (pH = 7.4). We aim to design a morphine derivative that binds selectively within inflamed tissue using molecular extension and dissection techniques. Morphine binds to the μ-opioid receptor (MOR) when the biochemically active amine group is protonated. Fluorination of a β-carbon from the tertiary amine group led to …

Analysis And Methodology Of Helical And Flexible Homopolymer Monte Carlo Simulations, Nathan Roberts

Honors College Theses

The purpose of my work is to analyze the results of Monte Carlo simulations of various types of polymers: a helical homopolymer and a flexible homopolymer. Specific applications of Monte Carlo polymer simulations and parallel tempering replica exchanges are presented. Using temporal analysis, I aim to measure the efficiency of each type of simulation as it relates to equilibration time. For the helical homopolymer model, equilibration time is expanded upon to analyze the rate of structure generation and relevant hyper-phase diagram. Stable states for helical homopolymers will use data generated from parallel tempering replica exchange Monte Carlo simulations created by …

Bacterial-Mediated Photocatalytic Organic Oxidation, Peter J. Pellegrinelli

Theses and Dissertations

Bacteria, though well-known and widespread in scientific application, have plenty more opportunity to grow in the field of organic synthesis. The primary objective of this project was to apply the use of bioluminescent bacteria in an organic photoredox reaction intending to use the bacteria as a renewable source of light. This sustainable method, as opposed to high wattage bulbs, paves a green pathway for organic photocatalytic reactions. Using bioluminescent E. coli, the focus was on performing organic oxidation reactions with a recyclable photocatalyst. When using bacteria in conjunction with chemicals like nitromethane, it was an obstacle to keep the E. …

A Meta-Narrative Review Of Runx1-Runx1t1 And Its Relativity To Cbf Disruption Within The Adult Population, Duong Do, Alma Guerrero, Fatima Osorio Guzman, Robert Hernandez, Aml Ibrahim, Andrea Nguyen

Research Methods Poster Session 2023

Acute Myeloid Leukemia (AML) is an aggressive subgroup of leukemias developed from a deviant hematopoietic stem cell, prevented from differentiating into a mature cell. Additionally, core binding factor (CBF) is disrupted by the translocation of chromosomes 8 and 21. This balanced translocation generates the RUNX1-RUNX1T1 fusion gene on the derivative chromosome 8, resulting in t(8;21)(q22;q22.1). These events cause a blockage of hematopoietic stem cell differentiation and ultimately lead to leukemia transformation (Beghini, A. 2019). Using Fluorescence in situ hybridization (FISH) and Karyotyping, molecular translocation can be detected, visualized, and associated with chromosomes 8 and 21 [t(8;21)(q22;q22)]. Furthermore, this study will …

Interactions Between Metabolism And Growth Can Determine The Co-Existence Of Staphylococcus Aureus And Pseudomonas Aeruginosa, Camryn Pajon, Marla C.

Biology Faculty Articles

Most bacteria exist and interact within polymicrobial communities. These interactions produce unique compounds, increase virulence and augment antibiotic resistance. One community associated with negative healthcare outcomes consists of Pseudomonas aeruginosa and Staphylococcus aureus. When co-cultured, virulence factors secreted by P. aeruginosa reduce metabolism and growth in S. aureus. When grown in vitro, this allows P. aeruginosa to drive S. aureus toward extinction. However, when found in vivo, both species can co-exist. Previous work has noted that this may be due to altered gene expression or mutations. However, little is known about how the growth environment could influence the …

Optimal Method For Reconstructing Polychromatic Maps From Broadband Observations With An Aysmmetric Antenna Pattern, Brianna Cantrall, Emory F. Bunn, Solomon Quinn

Honors Theses

Broadband time-ordered data obtained from telescopes with a wavelength-dependent, asymmetric beam pattern can be used to extract maps at multiple wavelengths from a single scan. This technique is especially useful when collecting data on cosmic phenomena such as the Cosmic Microwave Background (CMB) radiation, as it provides the ability to separate the CMB signal from foreground contaminants. We develop a method to determine the optimal linear combinations of wavelengths (“colors”) that can be reconstructed for a given telescope design and the number of colors that are measurable with high signal-to-noise ratio. The optimal colors are found as eigenvectors of a …

Length Bias Estimation Of Small Businesses Lifetime, Simeng Li

Honors Theses

Small businesses, particularly restaurants, play a crucial role in the economy by generating employment opportunities, boosting tourism, and contributing to the local economy. However, accurately estimating their lifetimes can be challenging due to the presence of length bias, which occurs when the likelihood of sampling any particular restaurant's closure is influenced by its duration in operation. To address the issue, this study conducts goodness-of-fit tests on exponential/gamma family distributions and employs the Kaplan-Meier method to more accurately estimate the average lifetime of restaurants in Carytown. By providing insights into the challenges of estimating the lifetimes of small businesses, this study …

Elementary School Parent Perceptions Of “Critical Race Theory” In The Curriculum, Helen Wallace

Honors Theses

Critical Race Theory (CRT) implementations within educational settings is a controversial and polarizing concept in the American political climate. Many Americans are strongly opposed to the idea of CRT within the classroom due to a misguided belief that children have no idea what race or racism is until it is taught to them explicitly. On the other hand, proponents of CRT argue that teaching children to ignore race further perpetuates racial discrimination and prevents children from adequately understanding racial injustice. There is currently a lack of research investigating perceptions of CRT implementations in education among parents. This research aimed to …

An Exploration Of The Experience Of Leisure Among Adults Who Immigrated To The United States From Latin American Countries, Violeta Chavez Serrano, Jazminne Orozco Arteaga, Karen Mccarthy

Spring 2023 Virtual OTD Capstone Symposium

Kaplan (1975) defined leisure as a self determined activity that is pleasant and allows for personal growth. Although the diversity among the population in the United States has continued to increase over the past years (United States Census Bureau, 2019) the amount of leisure research related to race and ethnicity is relatively limited. According to Floyd et al., (2008) only 4.5% of published articles highlighted the impact of race and ethnicity on leisure. Exploring how personal context influences occupational engagement, by examining a specific group's experience engaging in an occupation can help further develop the understanding of how personal factors …

Disciplinary System, Academic System And Discourse System Of Technological Sciences, Zhongkai Yang, Deming Lin, Yongxia Liang

Bulletin of Chinese Academy of Sciences (Chinese Version)

In 1957, Tsien Hsue-shen published an article entitled “On the Technological Sciences” in Chinese Science Bulletin, which laid the foundation for the research of technological sciences in China. However, in the following 60 years, the thought of technological sciences failed to receive stable attention and support. It was not until 2021 when General Secretary Xi Jinping made another important statement at the 20th Academician Conference of the Chinese Academy of Sciences, the 15th Academician Conference of the Chinese Academy of Engineering, and the 10th National Congress of the China Association for Science and Technology that technological sciences had entered into …
