Using Fundamental Properties Of Light To Investigate Photonic Effects In Condensed Matter And Biological Tissues, Laura A. Sordillo
Dissertations and Theses
Light possesses characteristics such as polarization, wavelength and coherence. The interaction of light and matter, whether in a semiconductor or in a biological sample, can reveal important information about the internal properties of a system. My thesis focuses on two areas: photocarriers in gallium arsenide and biomedical optics. Varying the excitation wavelength can be used to study both biological tissue and condensed matter. I altered the excitation wavelengths to be in the longer near-infrared (NIR) optical windows, in the shortwave infrared (SWIR) range, a wavelength region previously thought to be unusable for medical imaging. With this method, I acquired high …

However, they report low confidence in their knowledge and understanding of genomics and the genetically engineered medications prescribed for their patients. The purpose of this project was the development and implementation of an evidence-based online education program about genetics and genomics to increase the nurses' understanding and ability to provide competent care for their patients receiving treatments based on the science of genomics. Knowles's principles of adult learning theory guided the development and delivery of the online education project to 12 medical-surgical registered nurses employed in a hospital in the …
Improving Dopamine Monitoring With Ncam And The Effects Of Intranasal Oxytocin On Dopamine Signaling In The Rat Brain, Darren Earl Ginder
Improving Dopamine Monitoring With Ncam And The Effects Of Intranasal Oxytocin On Dopamine Signaling In The Rat Brain, Darren Earl Ginder
EWU Masters Thesis Collection
Dopamine (DA) is a neurohormone highly involved in learning and memory. Oxytocin (OXT), another neurohormone, has also been implicated in learning and memory. Fast-scan cyclic voltammetry (FSCV) is a method used for the real-time examination of DA neurotransmission in the brain. Implanting FSCV electrodes is an invasive technique that likely results in an inflammatory response (i.e. gliosis) that can restrict FSCV recording of DA signals. Neural cell adhesion molecule (NCAM) may reduce gliosis and potentially improve the ability of FSCV electrodes to monitor DA signaling. Chapter 1 Methods: FSCV electrodes were coated with NCAM and implanted in the rat brain. …

Alternative Treatment Options For Controlling Anthelmintic-Resistant Haemonchus Contortus Populations In South Dakota Sheep Herds, Adam Sarah
Electronic Theses and Dissertations
Haemonchus contortus is a common economically important gastrointestinal nematode that obliges the survival and productivity of small ruminants, especially sheep and goats. Anthelmintic resistance is a primary challenge in ruminant health management programs in preventing and controlling the H. contortus populations; therefore, there is a great necessity in finding and developing natural plant products for use as alternatives to commercial anthelmintics for controlling H. contortus in pastured sheep and goats. This dissertation has three major aims conducted in three separate studies: the first in vivo one was to evaluate the extended effect of a springtime, combined-treatment with 3 anthelmintics having …

Evaluations Of Health In Sympatric Free-Ranging Saguinus Imperator And Leontocebus Weddelli Using Neopterin, Urinalysis, And Blood Chemistry Analyses, Alexandra J. Sacco
All Master's Theses
This thesis is composed of one journal-ready article and one chapter that includes a preliminary interpretation of data for later publication. In summary, this thesis proposes the use of three different methods of evaluating the health status of New World Monkeys: urinary neopterin measurement, blood chemistry analyses, and urinalysis. Chapter II addresses the question of whether or not the neopterin molecule, a biomarker for cell-mediated immune system activation, is conserved across primate taxa. To do so, we collected urine samples across three New World Monkey (NWM) families including captive Leontopithecus rosalia and Pithecia pithecia, and wild populations of Leontocebus …
Characterization Of The Microbial Phosphonate-Activating Pntc Enzymes, Kyle Rice
Characterization Of The Microbial Phosphonate-Activating Pntc Enzymes, Kyle Rice
Theses and Dissertations (Comprehensive)
New strategies are urgently needed to combat infectious diseases in an era of rising antibiotic resistance. Furthermore, an emerging appreciation for the human microbiome’s role in maintaining health motivates discovery of species-specific antibiotics that minimally disrupt our native bacterial communities. Small molecule modifications to bacterial cell surfaces represent a potentially rich source of new targets for next generation antibiotics, as these molecules mediate virulence and evasion of the host immune response. Phosphocholine (PCho) is a rare cell surface modification that contributes to virulence, and modifications with phosphonates like 2-aminoethylphosphonate (AEP) are even more unusual and therefore provide opportunities for species- …

Graduate Student Theses, Dissertations, & Professional Papers
Introduction: Wildland firefighters (WLFF) work long hours in extreme environments resulting in high daily total energy expenditure (TEE). Increasing work shift eating episodes and/or providing rations that promote convenient feeding has shown augmented self-selected work output, as has regular carbohydrate (CHO) consumption. It remains unclear how current WLFF feeding strategies compare to more frequent nutrient delivery. Our study’s aim was to determine WLFFs’ self-selected field total energy intake (TEI), composition, and patterns feeding during wildland fire suppression shifts.
Methods: 86 WLFF (16 female, 70 male; 27.5 ± 6.4 yr) deployed to fire incidents across the United States throughout the 2018 …

Graduate College Dissertations and Theses
Sugar-Sweetened Beverages (SSBs) are liquids sweetened with various forms of added sugar. They are the leading source of calories and added sugar in the American diet (Drewnowski & Rehm, 2014; National Cancer Institute, 2016; Powell, Chriqui, Khan, Wada, & Chaloupka, 2013). The health and nutrition literature has increasingly identified added sugars and SSBs as a key potential contributor to a host of public health issues including obesity, type 2 diabetes, hypertension, and cardiovascular disease (Johnson et al., 2009; Malik, Popkin, Bray, Despres, & Hu, 2010; Vartanian, Schwartz, & Brownell, 2007). Concern about these public health crises has recently animated regional …

Association Of Sickle Cell Trait With Exertional Rhabdomyolysis And Atrial Fibrillation., Daniel R. Douce
Graduate College Dissertations and Theses
Sickle cell trait (SCT), sickle cell disease’s carrier status, is a common genetic variant found in many people of African, South Asian, Middle Eastern and Mediterranean descent. While overall considered a benign carrier status, it has been associated with an increased risk of several diseases, including exertional rhabdomyolysis (ER), and chronic kidney disease. While epidemiological evidence links SCT with ER, the actual pathophysiological mechanism less understood. Additionally, while there is an increased prevalence of atrial fibrillation (AF) documented in people with sickle cell disease, studies in individuals with SCT are lacking.
The objectives of this thesis are twofold: The first …
