A Prototype Miniaturized Metabolic Gas Analysis Sensor, Tammy Anderson, Joseph Orr

Utah Space Grant Consortium

Microgravity adversely affects several physiological systems. As space exploration moves to extended flights, understanding which mechanisms microgravity influences may contribute to the health and safety of astronauts aboard. Maximum oxygen consumption (VO₂ max) testing is used to monitor changes to cardiorespiratory function. Currently the equipment used to such testing aboard the International Space Station (ISS) is large and requires a significant amount of power. We propose the use of a modified metabolic management system, currently approved for clinical use, for exercise stress testing.

Resistance Training Increases The Expression Of Ampk, Mtor, And Glut4 In Previously Sedentary Subjects And Subjects With The Metabolic Syndrome., Andrew Steven Layne

Electronic Theses and Dissertations

Exercise has been considered a cornerstone of diabetes prevention and treatment for decades, but the benefits of resistance training are less clear. Nineteen non-diabetic subjects (10 metabolic syndrome, 9 sedentary controls) underwent 8 weeks of supervised resistance training. After training, strength and V̇ O_2max increased by 10% in both groups. Percent body fat decreased in subjects with the metabolic syndrome. Additionally, lean body mass increased in both groups (p<0.05). Expression of glucose transporter protein-4 (GLUT4), the principle insulin-responsive glucose transporter, increased significantly in both groups. 5-adenosine monophosphateactivated protein kinase (AMPK) and mammalian target of rapamycin (mTOR) expression increased in both groups, indicating increased protein synthesis and mitochondrial biogenesis. Markers of insulin resistance measured by a euglycemic hyperinsulinemic clamp did not improve in subjects with the metabolic syndrome but increased significantly in control subjects (13%). Resistance training upregulates intracellular signaling pathways that may be beneficial for ameliorating the metabolic syndrome.

Inhibition Of Escherichia Coli Atp Synthase By Polyphenols And Their Derivatives., Prasanna Keerthi Dadi

Electronic Theses and Dissertations

We have studied the inhibitory effect of natural and structurally modified polyphenols on Escherichia coli ATP synthase to test (I) if the beneficial dietary effects of polyphenols are related to their inhibitory actions on ATP synthase, (II) if inhibitory effects of polyphenolic compound could be augmented through structural modifications, and (III) if they can act as antimicrobial agent through their actions on ATP synthesis. X-ray crystal structures of polyphenol binding sites suggested that polyphenols bind at a distinct polyphenol binding pocket, at the interface of α,β,γ-subunits. We found that both natural and modified polyphenols inhibit E. coli ATP synthase to …

These findings can help the consumers to determine if the vegetable products are within the recommended maximum limits as proposed by the joint FAO/WHO Expert committee on organic foods designation. Eight edible vegetables were purchased from local stores in both the organic and conventionally grown categories. Samples were digested with concentrated nitric acid and the metals monitored were zinc, copper, lead, iron, cadmium, and nickel using flame atomic absorption. The concentration range for …

At-Risk Indicators: The Impact On School Success., Lisa Wynn Stewart

Electronic Theses and Dissertations

The hope of educators is that children will obtain a strong educational foundation that will lead to life-long learning and a bright future. However, several factors may play a role in hindering a successful outcome. Addressing the at-risk indicators of excessive absences, discipline referrals, socioeconomic status, disability status, early grade retention, and family composition gives insight into struggles students face.

Looking at 6 research questions, an independent sample t test was used to determine the difference in students who had excessive absences and discipline referrals in relation to school success. A chi-square analysis was used to identify the relationship between …

Job Satisfaction In Young Professional Athletic Trainers, Jennifer Stollery

Masters Theses, 2010-2019

Job satisfaction levels in young professional athletic trainers in multiple settings were examined quantitatively using the Job Satisfaction Survey (Spector, 1997) and qualitatively using an open-ended survey question. Job satisfaction levels were calculated to find that young professional athletic trainers are satisfied with their jobs according to the normative mean data for the scale. Post hoc analysis of the comparison of satisfaction levels by setting suggests that college/university athletic trainers have significantly lower job satisfaction levels than secondary school and clinic/outreach athletic trainers. Qualitative data suggests a high negative response rate revealing pay and operating procedures as two of the …

Investigation Of The Role Of Bam9 In Starch Metabolism In Arabidopsis Thaliana, Elizabeth Ann Steidle

Masters Theses, 2010-2019

Beta-amylases play an essential role in night time starch degradation in leaves. There are nine known beta-amylases (BAMs) in Arabidopsis thaliana. This research is focused on BAM9, which is localized in the chloroplasts but is unique compared to active BAM proteins. First, alignments of BAM9 orthologs and catalytically active paralogs suggest that BAM9 may not be catalytically active and may not bind to starch, but it may bind to another molecule at a remote site. Secondly, microarray data shows a peak of BAM9 expression at the dark/light transition which is contradictory to what one would expect for an active BAM …

The Relationship Between Blood Iron Markers, Nutritional Intakes And Bone Mineral Density, Leah Dawn Morrison

Masters Theses, 2010-2019

PURPOSE: The purpose of this study was to examine the relationship between serum ferritin (sFer) levels, nutrient intake of iron, calcium and vitamin D and bone mineral density (BMD) in female collegiate athletes. It was hypothesized that if an individual had low sFer (20µg/L. An independent T-test also showed no mean differences in BMD levels at any site when the group was divided into high and low sFer levels. CONCLUSION: There was no correlation between sFer level and BMD or between BMD and intake levels of iron, calcium or vitamin D, in female collegiate athletes participating in weight bearing sports. …

Endodontic Residents’ Understanding Of Biostatistics: A 2010 Survey Of Endodontic Residents In The United States, Paul Letellier Jr.

Theses and Dissertations

Endodontic residents must keep current with clinical information to practice evidence- based dentistry. To do so, endodontic residents must access research papers and interpret results. This requires a knowledge of biostatistics. However, the biostatistical knowledge of endodontic residents is relatively unknown. The purpose of the study was to assess the biostatistical knowledge of endodontic residents using a survey instrument to prove or reject the hypothesis that there exists a lack of understanding of biostatistic principles among endodontic residents. A survey consisting of 29 questions querying attitudes and biostatistical knowledge was distributed to 230 endodontic residents and returned with a 32% …

Interteaching And The Testing Effect: How Quizzes Alter The Efficacy Of Interteaching, Tonya Lambert

Masters Theses, 2010-2019

In recent years, educational systems have come under great scrutiny. In response to this scrutiny, researchers have developed numerous behavior-analytic teaching methods, the most recent being interteaching. In a growing number of studies, interteaching has proven to be more effective than traditional methods of instruction, but little research has examined ways to make interteaching even more effective. Research on the testing effect suggests that frequent testing may improve student-learning outcomes. Thus, including post-discussion quizzes as a part of interteaching might be one way to make it more effective. In the present study, participants completed interteaching in a simulated classroom setting. …

System Dynamics Of Diabetes In The Presence Of Social Determinants, Victoria Akins

Masters Theses, 2010-2019

Diabetes is a chronic and persistent disease that is on the rise in the U.S. in spite of medical advances and current public health efforts to address it. There is a relationship between socioeconomic factors such as poverty and education and the risk of developing diabetes and the progression of the disease. A systems approach is employed to develop a dynamic hypothesis with a stock and flow model will uncover and analyze these relationships to gain a better understanding of the socioeconomic dynamics of diabetes. Social factors have a significant impact on health outcomes and their consideration is essential to …

The Homestead: Revisited, Christopher William Kramer

This paper discusses ideas for harmony on 100 acres in mid-eastern New York. Problems leading to this research include the depletion of resources from irresponsible energy use and profit-driven industrial agriculture; dependency on fossil fuels and centralized energy; and lack of connection between people within communities, with their environment, and with sources of food and water. It is feared that sustainable, resilience building practices that nourished generations throughout history are being neglected. This specific application provides depth and concreteness to the discussion and planning process. Resources including books, maps, reports, and periodicals were integrated to select the site and plan …

Hydrogen Production By The Unicellular Diazotrophic Cyanobacterium Cyanothece Atcc Sp. Strain 51142 Under Continuous Light., Hongtao Min, Louis A. Sherman

Department of Biological Sciences Faculty Publications

We report on the hydrogen production properties of the unicellular, diazotrophic cyanobacterium Cyanothece sp. strain ATCC 51142. This organism has a versatile metabolism and can grow in the presence or absence of combined nitrogen and can grow photosynthetically or mixotrophically and heterotrophically in the presence of glycerol. The strain produces a bidirectional hydrogenase (encoded by the hox genes), an uptake hydrogenase (hupLS), and nitrogenase (nifHDK). We demonstrated hydrogen production by both the hydrogenase and the nitrogenase under appropriate metabolic conditions. The highest rates of hydrogen production were produced under nitrogen-fixing conditions when cells were grown and …

The Effect Of Medicaid Policy Reform On Dental Utilization Rates For Children, Matthew Winheim

Theses and Dissertations

Background: Regular access to dental services is a well-known factor in the oral health and development of children.1 As such, the United States federal government mandates each state to include dental services for children enrolled in Medicaid through the age of 21. Despite this mandate, the utilization rate of dental services among Medicaid enrolled children has remained remarkably low.2 In July 2005, Virginia implemented a sweeping Medicaid policy reform titled “Smiles for Children,” specifically aiming to increase Medicaid pediatric dental utilization rates. The purpose of this study aims to assess the effect of this 2005 policy reform on the utilization …

The Association Between Prenatal Care Content And Quality With Preterm Birth And Maternal Postpartum Health Behaviors, Susan Cha

Theses and Dissertations

Background: Health policies that seek to improve pregnancy outcomes focus on increasing the availability and access to prenatal care (PNC) services based on studies that support an association between insufficient PNC and adverse birth outcomes. These studies employ PNC utilization indices that measure the adequacy of PNC use, but these indices fail to account for the content or specific components of PNC. Objectives: The purpose of this study was to utilize PRAMS and birth certificate data to evaluate the content and quality of PNC in Virginia, and its impact on preterm birth and maternal postpartum health behaviors. Methods: Data was …

Purpose: The purpose of this study is to conduct a secondary analysis to explore demographic variables (race, gender, academic performance, living arrangement, alcohol and other drug usage, and …

Is Food Insecurity A Contributing Factor To Childhood Obesity? The Association Of Household Food Insecurity And Obesity Prevalence Among Children And Adolescents In The United States, Zarah Liz Panaguiton

Theses and Dissertations

The obesity epidemic is a major public health concern, where the prevalence rates amongst the American children population have more than doubled since the 1980s. Among overweight children, the risk of becoming an overweight or obese adult is 70% higher than children of normal weight, and obese children are more likely to remain obese into adulthood and face a number of morbidities associated with it, including lower quality of life and increased financial burden. In this research, we examined the relationship between household food security and obesity among children and adolescents between the ages of 2-18 years old. We used …

Biobehavioral Mechanisms Of Emotion And Hiv Disease: Exploring Potential Mediators Of The Relation Between Trait Positive And Negative Affect And Hiv Health Status, Karen Stewart

Theses and Dissertations

Considerable research supports an association between negative psychosocial functioning and adverse health outcomes. The biobehavioral model is well supported and posits that these effects occur via alterations in physiological response and health damaging behaviors. Evidence is accumulating about potential benefits of positive psychosocial functioning; however, less is known about the mechanisms of these effects. The broaden-and-build model of positive emotions holds that positive emotions can undo the physiological and behavioral restrictions associated with negative emotions and promote resource development. The present correlational study sought to explore whether cortisol, medication adherence, and health behaviors (smoking, alcohol use, physical activity, and nutrition) …
