Characterization Of A Protein-Small Molecule Interaction Between Microtubules And Novel Ruthenium-Polypyridyl Complexes, Chloe Hutchison

Chemistry & Biochemistry Undergraduate Honors Theses

Microtubules are cytoskeletal filaments that play a role in essential functions within the cell such as cell motility, intracellular transport, structural support and chromosome segregation. Tubulin is a heterodimeric protein that exhibits GTP dependent polymerization and self- assembles into polar microtubule filaments. Microtubules are dynamic polymers corresponding to their role in separation of duplicated chromosomes during mitosis. As the polymers cycle through rounds of polymerization and depolymerization based on their nucleotide state, the chromosomes are pulled towards the poles in the mitotic cell. Their normal function and dynamics can be disrupted in highly proliferative cells that interrupt cell cycle progression …

Exercise Counteracts The Deleterious Effects Of Cancer Cachexia, Stavroula Tsitkanou, Kevin A. Murach, Tyrone Washington, Nicholas P. Greene

Health, Human Performance and Recreation Faculty Publications and Presentations

Cancer cachexia (CC) is a multifactorial syndrome characterised by unintentional loss of body weight and muscle mass in patients with cancer. The major hallmarks associated with CC development and progression include imbalanced protein turnover, inflammatory signalling, mitochondrial dysfunction and satellite cell dysregulation. So far, there is no effective treatment to counteract muscle wasting in patients with CC. Exercise training has been proposed as a potential therapeutic approach for CC. This review provides an overview of the effects of exercise training in CC-related mechanisms as well as how factors such as cancer comorbidities, exercise modality and biological sex can influence exercise …

Attention, Reflection, And Contemplation: Approaching The Divine Through Romantic Poiesis, Katelynn Tyner

English Undergraduate Honors Theses

Often the techniques of the said and the unsaid work together. This paper will explore ways in which poets embrace iconophilic or iconoclastic postures toward divine poiesis. One objective will be to focus on the arrangement of an abundance of images into itineraries and poetic landscapes. Another objective will be to demonstrate how these patterns of cultivation can be related to a divine poiesis. Through poetry, there are ways of attending to, reflecting on, and contemplating divine images that can return us to forms of participation with the sacred. First examining poetic attention, I identify poets who demonstrate …

Concurrent Load And Construal On Planning, Maximilian Fey

Graduate Theses and Dissertations

Planning for the future is a necessary activity which spans across all aspects of an individual’s life. Concurrent cognitive load has been shown to hinder future planning, whereas concrete construal of events has been shown to increase planning efficacy. Interestingly, a limited literature speaks towards cognitive load inducing concrete construal. However, the two constructs predict differing outcomes on future planning therefore the interaction of cognitive load inducing a concrete construal is particularly interesting. The research study tested whether differing levels of concurrent cognitive load increase or decrease planning efficacy. The intention of the research was to elucidate whether cognitive load …

Law Enforcement Policy And Personnel Responses To Terrorism: Do Prior Attacks Predict Current Preparedness?, Bryce Kirk

Graduate Theses and Dissertations

Terrorism has been on the mind of the American people and politicians alike since the 9/11 attacks over two decades ago. In the years since, there has been a massive shift in law enforcement priorities from community-oriented policing (COP) to homeland security-oriented policing. This was especially evident in the establishment of the Department of Homeland Security (DHS) shortly after the attacks on the World Trade Center and Pentagon in 2001, which was established to aid law enforcement entities with terrorism preparedness. While prior literature has addressed a variety of factors that have contributed to terrorism preparedness, very little research has …

Macronutrient Availability Shapes Host Response To Infection And Feeding Behavior, Weston Gerald Perrine

Graduate Theses and Dissertations

Macronutrients in the diet are vital to the physiological processes necessary for an organism to effectively clear a pathogen. Diet can be important to a host’s susceptibility to infection and severity of pathology, though results can vary across host-pathogen systems (Sen et al. 2016). Manipulating the ratio of specific macronutrients in the diet is an effective method to begin understanding how individual macronutrients, rather than food types, have on immune responses. Using an avian host-pathogen system, I explored the effects of dietary macronutrient composition, specifically lipid and protein content, on disease pathology and behavior of canaries (Serinus canaria) infected with …

Public Libraries In Rural Arkansas: An Oasis In An Information Desert, Britt Graves

Graduate Theses and Dissertations

Public libraries in Arkansas are welcome, but those found in rural Arkansas are almost a necessity. The public uses the library for more than just checking out books or their email: it’s become a community gathering place for all walks of life, regardless of age or economic status. When the Covid-19 pandemic hit the state, libraries also became essential for education, medicine, news, and employment, nearly overloading their resources and shining a spotlight on technology, or the lack thereof, that so many public libraries are needing. With the Arkansas governor planning an upgrade on broadband technology and the federal government …

Essential Amino Acid (Eaa) Regulation Of Skeletal Muscle Protein Turnover With Age, Mary Komp

Graduate Theses and Dissertations

Skeletal muscle (SM) is vital for both long term health and quality of life. Recent research suggests an increase in catabolic signals with age triggers pathologic conditions, such as sarcopenia. Although results from in vitro studies model how EAA can regulate muscle protein synthesis (MPS), the relevance of these models to muscle protein breakdown (MPB) and the presence of physiological EAA concentrations remains to be established. Therefore, the objective of this study was to determine the effects of a low, normal, and supra physiological dose of EAA (0.2, 1.0, and 3.0 x EAA) in a young (passages 2-10) and aging …

Reconstructing Bison And Mammoth Migration During The Late Pleistocene And Early Holocene Of Central Texas Using Strontium Isotopes, Joshua John Porter

Graduate Theses and Dissertations

During the Late Pleistocene (LP; past 130,000 years), over two-thirds of large mammal (>45kg) species went extinct globally. While the role of humans is hotly debated, the effect of these extinctions is growing clearer; the extinctions resulted in widespread and lasting faunal community reorganization. However, the impact of these extinctions on dietary and migratory behavior within faunal communities is unknown. Our study examines the impact of the megafaunal extinctions on the dietary and migratory behavior of surviving Bison individuals in Texas using carbon, oxygen, and strontium isotopes. Strontium isotopes are incorporated into mammalian enamel during their tooth development and …

Archivos Del Fracaso: La Escritura De La Memoria Histórica En Cuatro Novelas Documentales Latinoamericanas Del Siglo Xxi, Vanessa Guerrero

Graduate Theses and Dissertations

This doctoral dissertation aims to study four Latin American documentary novels of the 21st century. This type of novel is especially characterized by its deep and direct connection with historical archives, its high degree of auto fictionality and the self-awareness elaboration of an extreme ambiguity between fictionality and factuality. Likewise, this research proposes a reading of this type of novels through what has been called the poetics of failure, which configures not only the defeat of the characters within the plot, but also offers an ethical and aesthetic position in order to represent historical memory in a different way.

Evaluating The Effects Of Cardiorespiratory Fitness Level And Gender On Outcomes Of The Buffalo Concussion Bike Test, Katie Stephenson

Graduate Theses and Dissertations

Background: Accurate assessment of concussion is crucial for creating a treatment plan. The Buffalo Concussion Bike Test (BCBT) is a 30-minute graded exercise protocol for a stationary bicycle. Previously this assessment has been reportedly used to screen for exercise intolerance secondary to autonomic dysfunction; however, the original purpose of the assessment was to find a sub-symptom threshold for exercise rehabilitation during concussion recovery. Starting resistance for the BCBT protocol is based solely on body mass. Other factors such as cardiorespiratory fitness level and sex have been noted to effect outcomes on similar assessments and are not considered in the BCBT …
