The Role Of Protein Degradation In Cancer Cachexia In Female Tumor Bearing Mice, Noah Thomas

Graduate Theses and Dissertations

Background: Cancer is a leading cause of death in the world in which half of the people affected by this disease die from its effects. Cancer-cachexia is a syndrome associated with the significant loss of skeletal muscle mass and function, which cannot be fully reversed by nutritional intervention alone and in turn, impairs the host. Cancer-cachexia affects 50-80% of cancer patients and is a primary cause of death accounting for 20-40% of cancer related deaths. Efforts to reverse the effects of cancer-related cachexia have been largely unsuccessful and have primarily focused on the late stages of CC. Methods: Lewis Lung …

Barriers To Integrated Primary Care And Specialty Mental Health Services: Perspectives From Latinx And Non-Latinx White Primary Care Patients, Elizabeth A. Anastasia

Graduate Theses and Dissertations

High need, low access, and rising health care costs reveal the inadequacies of the current mental health system in the U.S. Racial/ethnic minorities, including Latinxs, face substantial disparities in accessing mental health treatment compared with non-Latinx Whites. Integrated primary care (IPC) offers an alternate model for meeting mental health needs by providing care in a way that is accessible to the general population. Though it has been suggested that IPC may reduce health disparities by decreasing barriers to mental health treatment, empirical data relevant to this question are limited. A series of three studies were conducted using a mixed methodology …

Preliminary Study: Leucine Supplementation Exacerbates Muscle Wasting Independent Of The Ubiquitin-Proteasome System, Katarina Bejarano

Graduate Theses and Dissertations

Cancer cachexia is the rapid, drastic loss of muscle mass associated with cancer and is not reversible by conventional nutritional means (Brown et al., 2018; Brown et al., 2017). It occurs in ~80% of cancer patients and is responsible for 20-40% of cancer-related deaths (Brown et al., 2018; Brown et al., 2017). This condition leaves patients with fatigue, functional impairment, reduced quality of life, and a decrease in survival rates. Cachexia occurs through an imbalance between protein degradation and protein synthesis (Brown et al., 2018), which is associated with inflammation and altered metabolic processes.

Several studies have investigated the effects …

The Effect Of Breakfast Macronutrient Composition In Children Ages 7-17 Years Old As A Potential Method To Combat Childhood Obesity, Angela M. Tacinelli

Graduate Theses and Dissertations

The prevalence of childhood overweight and obesity is an ongoing concern. Currently, approximately 20% of children in the United States are obese. While obesity was once regarded merely as excessive adiposity within the body, it is has emerged as a major risk factor for chronic diseases such as metabolic syndrome, type 2 diabetes, and cardiovascular disease. Obesity is multifactorial in nature. Weight gain can result from an energy imbalance in the body due to excess energy intake (calories in) and decreased energy expenditure (calories out). Identifying methods to combat obesity is essential. Nutritional intervention may be a strategy to help …

An Evaluation Of Unmanned Aircraft Systems' Ability To Assess Stripe Rust In Large Wheat Breeding Nursies, Jamison T. Murry

Graduate Theses and Dissertations

Stripe Rust (Puccinia striiformis f. sp. tritici) is a foliar disease that significantly impacts global wheat production, and resistant cultivars provide the most efficient method of control. High-throughput phenotyping using unmanned aircraft systems (UAS) offers a potentially more efficient method for field-based phenotyping compared to visual assessment. Here we tested the ability of remote sensing to predict stripe rust severity in a diverse population of 594 soft red winter wheat lines, planted in single-rows, and evaluated them by visually rating stripe rust intensity and remotely using the dark green color index (DGCI), normalized difference vegetation index (NDVI) and blue NDVI. …

Structural And Functional Characterization Of Mitochondria With Trna Mutations, Brooke Henry

Biological Sciences Undergraduate Honors Theses

Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is one of the most common disorders associated with mitochondrial tRNA mutations. One of the most common causes of MELAS is mutation in the MT-TL1 gene which codes for mitochondrial tRNA Leucine (UUR). Mutation in MT-TE gene, another mitochondrial gene which encodes for mitochondrial tRNA Glutamate (GAA/G), has been implicated in various mitochondrial related myopathies. It remains unclear how point mutations in these tRNA genes result in disease onset and progression. Here, we report an early comparative analysis of fibroblast cell lines derived from patients carrying two different tRNA mutations: m.3243A>G …

Cultivating Alternative Subsistence Farming Practices In Dangriga, Belize, Alexander Johnson

Economics Undergraduate Honors Theses

Subsistence farming, also referred to as backyard farming, is an important opportunity for families in areas of low economic status. Small scale poultry farming is another practice often used by families in similar situations because of the financial and nutritional benefits provided. By combining the two practices in a process where they each benefit from the other, a sustainable system can be created. The poultry-garden system can provide a source of food for the household and, if run effectively, supplemental income can be generated through the sale of excess poultry, eggs, or vegetation. This project attempted to take the concept …

Food Safety Risk In An Indoor Microgreen Cultivation System, Gina Marie Misra

Graduate Theses and Dissertations

Microgreens are immature sprouts of edible plants, sharing some similarities with sprouted seeds and petite leafy greens. Since they are most often grown in containers in buildings or greenhouses, they present a new area for food safety research at the intersection of the built environment and produce farming. Contamination by human pathogens has been extensively studied in other types of produce typically eaten raw, including sprouted seeds, which have been implicated in numerous outbreaks of salmonellosis over the last several decades. There is a paucity of knowledge about the microgreen sector of the fresh-cut industry; thus, it was determined that …

A Putative Cystathionine Beta-Synthase Homolog Of Mycolicibacterium Smegmatis Is Involved In De Novo Cysteine Biosynthesis, Saroj Kumar Mahato

Graduate Theses and Dissertations

Mycobacteria include serious pathogens of humans and animals. Mycolicibacterium smegmatis is a non-pathogenic model that is widely used to study core mycobacterial metabolism. This thesis explores mycobacterial pathways of cysteine biosynthesis by generating and study of genetic mutants of M. smegmatis. Published in vitro biochemical studies had revealed three independent routes to cysteine synthesis in mycobacteria involving separate homologs of cysteine synthase, namely CysK1, CysK2, and CysM. However, in vivo data were lacking. The M. smegmatis genome encodes only a CysM homolog and lacks orthologs for CysK1 or CysK2. The gene that codes for CysM is a part of an …

Asymmetric Exchange Rate Pass-Through In Southeast Asian Rice Trade, Taylor Wiseman

Graduate Theses and Dissertations

Asian countries consume approximately 90% of the world’s rice supply. Between 2007 and 2014, Thailand, Vietnam, and India accounted for 60% of the world’s exports of rice. This paper estimates the impact of exchange rate fluctuations on bilateral trade flows in Southeast Asia. Because most Southeast Asian countries have state trading enterprises or agencies controlling rice trade, this analysis will provide insight as to whether these agencies respond to exchange rate fluctuations in a manner consistent with economic theory. Behavior inconsistent with economic theory could provide evidence of stabilizing domestic prices, market power, or export expansion policies. The analysis focuses …

The Impact Of The Arkansas Scholarship Lottery On College Choice And Completion Of Adult Students, Collin Callaway

Graduate Theses and Dissertations

In 2008, Arkansas citizens overwhelmingly supported a referendum to legalize a state-run lottery to support college scholarships. The Arkansas General Assembly passed a law in 2009 that detailed administration and procedures of the lottery, and students first received scholarships (branded as the Academic Challenge Scholarship) in fall 2010. The program was largely modeled after other state-run scholarships with two major exceptions: policy makers intentionally established lower eligibility requirements and included adult students. This study measured the impact of the state lottery funded Academic Challenge Scholarship on adult college choice and completion. Findings included significant demographic and college choice differences between …
