Articles

Nanoparticles use in nano-biotechnology applications have increased significantly with Aminated polystyrene amine (AmPs NP), Zinc oxide (ZnO NP), and Silver (Ag NP) nanoparticles utilized in wide variety of consumer products. This has presented a number of concerns due to their increased exposure risks and associated toxicity on living systems. Changes in the structural and physicochemical properties of nanoparticles can lead to changes in biological activities. This study investigates, compares, and contrasts the potential toxicity of AmPs, ZnO and Ag NPs on an in vitro model (HeLa cells) and assesses the associated mechanism for their corresponding cytotoxicity relative to the surface …

Effect Of Backgrounding Management Strategies On The Performance And Profitability Of Yearling Beef Cattle, Cody Alan Welchons

Department of Animal Science: Dissertations, Theses, and Student Research

Performance and profitability of steers grazing smooth bromegrass during the summer was evaluated. Steers grazed bromegrass with no supplement (CON), grazed bromegrass fertilized with 90 kg N/ha (FERT), or grazed bromegrass and were supplemented with distillers grains plus solubles (DGS) at 0.6% of BW (SUPP). Supplemented steers had increased ADG compared to CON and FERT steers. Profitability was greatest for the SUPP steers due to increased ending BW at the end of the grazing season. Steers grazing fertilized pastures were more profitable than CON steers due to increased stocking rate as a result of improved forage growth.

Association Between Diabetes And Cancer In Indian And Us Populations Using Longitudinal Study Design, Shraddha S. Vyas

Theses and Dissertations

Background: There is growing evidence of association between diabetes and cancer. No studies have been conducted in India evaluating this association. With the current epidemiologic, nutritional and economic transition in India, it becomes extremely important to examine this association in an Indian population. Additionally, difference in association exists based on different cancer subtypes. Research has shown that diabetes is associated with an increased risk of colorectal cancer. However most of these studies suggest detection bias to be one of the probable reasons for this association. Additionally, the common risk factors shared by both these conditions are considered to one of …

Paleodemographic And Biochemical Analysis Of Urbanization, Famine, And Mortality, Brittany S. Walter

Theses and Dissertations

Urbanization is a transitional period often associated with deteriorating population health and increased mortality, as the rapid increase of population density in urban centers facilitates the transmission of infectious diseases, unsanitary living conditions, and precarious food supplies. Research on the transition to an urban environment in the past offers a temporal depth to our understanding of the consequences of urbanization that cannot be accomplished through examination of contemporary populations. This project integrates paleodemographic (hazard analysis) and biochemical (stable isotope analysis) approaches to examine the health and diet of inhabitants in late medieval England (c. 1120-1539 CE), specifically the relationship between …

Maternal Physical Activity And Cardiorespiratory Fitness During Pregnancy And Its Relation To Infant Size, Samantha M. Mcdonald

Theses and Dissertations

Recent evidence indicates that U.S.-born infants are larger today compared to 20 years ago. A strong determinant of neonatal size is maternal body mass, where larger mothers deliver larger infants. Consistent evidence indicates that higher levels of maternal physical activity (PA) during pregnancy reduce the risk of delivering a larger infant. However, this protective effect has only been demonstrated in normal weight pregnant women. Little is known about the relationship between maternal PA and neonatal size in overweight or obese pregnant women. Moreover, no studies have examined the association between maternal cardiorespiratory fitness (CRF), an indicator of habitual PA, on …

This study took place during the Fall 2016 semester with six participants, two early childhood majors, two elementary majors, and two middle level majors. Data were collected through pre- and post-questionnaires, course assignments, and field observations. The results revealed that the teacher candidates were able to make connections between theory and reflective teaching, had varying viewpoints about the process of reflection, and most …

Children’S Obesogenic Behaviors During Summer Versus School, Keith Brazendale

Theses and Dissertations

Emerging evidence shows children gain 3-5 times the amount of weight and lose cardiorespiratory fitness (CRF) during summer compared to the 9-months of the school year. Notably, this trend is more pronounced in children who are already overweight or obese going into summer and/or from low-income ethnic minority households. There is little evidence to investigating the underlying mechanisms driving the pronounced occurrence of these negative health outcomes during summer.

The purpose of this dissertation as a whole was to investigate children’s obesogenic behaviors (physical activity, sedentary/ screen time, sleep, and diet) during summer versus school, and compare any differences in …

Identifying Associations Between Religious Commitment And Preventive Health Behaviors In A Southeastern Rural County, Nathan A. Peters

Theses and Dissertations

Health disparities within the United States (US) are continuing to impact ethnic minorities living in rural areas nationwide. In response, there is growing interest in using faith-based settings as vehicles to deliver much needed disease prevention interventions. However, few studies have identified the relationship between private and public religious commitment, individually, and the behaviors or risk factors associated with chronic disease. The purpose of this study was to observe the association between religious commitment, both private (i.e., time spent trying to grow in one’s religious understanding) and public (i.e., frequency of attendance, time spent in fellowship with others) individually, and …

Effects Of A Mindfulness Based Intervention On Diurnal Cortisol In Cancer Survivors, Susannah Small

Theses and Dissertations

Background. There are approximately 15.5 million individuals alive today in the U.S. with a personal history of cancer. For this large and growing population, ill effects associated with cancer diagnosis and treatment include both physical and psychosocial symptoms adversely affecting quality of life. One low-risk alternative to conventional pharmaceutical use in treating these symptoms is mindfulness practice. Research on self-reported measures provides strong evidence that this type of intervention improves quality of life for cancer survivors, but evidence of impact on objective measures is limited. Cortisol, the body’s primary stress hormone, is one relatively easy to measure indicator that …

Mercury Bioaccumulation In Three Popular Subsistence And Recreational Estuarine Fishes From Southeastern U.S.A., Taylor Cannon

Theses and Dissertations

A rising concern in recent years has occurred over the presence of methylmercury in seafood, particularly fishes, and its impact on human health. However, fish also provide many health benefits, including improved cardiovascular health and neurodevelopment. Because fishes are the main source of methylmercury exposure to humans, and are such an integral part of the human diet, understanding the risks versus the benefits of fish consumption is imperative in allowing the public to make healthy, educated choices. One way that state and federal governments attempt to do this is through issuing fish consumption advisories. Unfortunately, these advisories do not always …

Analysis Of Food Exposures In Foodborne Disease Outbreaks, Alecia T. Alianell

Theses and Dissertations

Foodborne illness remains a serious public health problem in the United States in general as well as South Carolina in particular. Obtaining good food ingestion histories as well as possible risky environmental exposures is one of the earliest, most important tasks to complete in any foodborne outbreak investigations. Because time is of the essence in investigations, we have evaluated a rarely used biostatistical method, Random Forests, to data obtained from DHEC. Random Forests has the potential to facilitate more rapid identification of foods or environmental exposures that may be associated with outbreaks. We also examined previous cases of salmonellosis using …

Contesting The Generic Refugee: Siv Identity, Community, And Agency During Resettlement, Benjamin J. Sylvester

Theses and Dissertations

This thesis examines the complexity of identity and community formation by Special Immigrant Visa (SIV) holders during resettlement in Columbia, South Carolina. It explores the ways in which identities coalesce around various themes, such as religion, gender, and military service, how these identities serve to create, expand, and claim membership in communities, and how SIVs exercise agency throughout these processes. Through semi-structured interviews with 9 SIVs in Columbia, SC, this qualitative study highlights the unique, highly individualized ways in which a select group of refugees experience resettlement, how they negotiate their placement within socio-economic hierarchies, and exercise agency to obtain …

The Nutrition Assistance Landscape In Afterschool Programs: Understanding The Gap Between Research, Policy, And Practice, Falon Elizabet Tilley

Theses and Dissertations

The Child and Adult Care Food Program (CACFP) aims to increase children’s access to healthful foods in out-of-home care. Approximately half of the 10.2 million children enrolled in afterschool programs (ASPs) are eligible for nutrition assistance through programs like CACFP. Despite awareness of its potential impact on the nutritional status of millions of children, CACFP is underutilized among ASPs and notably understudied in comparison to other federal nutrition assistance programs.

This dissertation addresses key gaps in CACFP research and provides a deeper understanding of the nutrition assistance landscape in afterschool programs by (1) assessing the type of afterschool snacks served …

UNAVOIDABLE PRESSURE ULCER: AN ETHNONURSING STUDY

In an effort to improve patient safety and the quality of care in the acute care setting, there has been an increased focus on the prevention of adverse events believed to be avoidable. Hospital-acquired pressure ulcers (HAPU) have been listed as one of those adverse events, and hospitals are no longer reimbursed for related costs. However, there are patient conditions and clinical situations in which a pressure ulcer can be deemed unavoidable. In acute care, unavoidable means that the patient developed a pressure ulcer even though the provider …

We Can Do Better: Evaluating An Intervention Remedying Caseworkers’ Negative Racial Bias Towards African American Families Involved In Child Welfare, Adrianne Michele Fletcher

Dissertations

Given that U.S. history documents the severing of African-American family ties by isolating parents from each other and their children under slavery, it is imperative that the child welfare system be free of any echoes of that holocaust. Yet many scholars and practitioners who lament negative racial attitude, both implicit and explicit, may continue to contribute to the over-representation of African-American children in the U.S. child welfare system. This study proposes to examine a subcategory of practitioner attitudes, those about the caregivers’ race, and how those attitudes can be altered through a reflective educational experience. Drawing from pre-existing research about …

Mutual Regulation Of Crp And N(Epsilon)-Lysine Acetylation In Escherichia Coli, Robert James Davis

Dissertations

Post-translational modifications, such as N(epsilon)-lysine acetylation, are known to alter the behavior of transcriptional regulators in eukaryotes, but very little is known about the consequences of acetylation on transcriptional regulation in bacteria. Here, I provide evidence that a global transcriptional regulator of carbon metabolism, cAMP Receptor Protein (CRP), promotes both enzymatic and non-enzymatic lysine acetylation in E. coli. Non-enzymatic lysine acetylation occurs when cells ferment acetate, such as during growth on high concentrations of glucose. Intriguingly, CRP can be non-enzymatically acetylated on several lysines, including lysine 100 (K100). I provide evidence that neutralization of the K100 positive charge, as would …

Faculty Publications

Many Americans are attempting to lose weight with the help of healthcare professionals. Clinicians can improve weight loss results by using technology. Accurate dietary assessment is crucial to effective weight loss. The aim of this study was to validate a computer-led dietary assessment method in overweight/obese women. Known dietary intake was compared to Automated Self-Administered 24-h recall (ASA24) reported intake in women (n = 45), 19–50 years, with body mass index of 27–39.9 kg/m2. Participants received nutrition education and reduced body weight by 4%–10%. Participants completed one unannounced dietary recall and their responses were compared to actual intake. Accuracy of …

Latino Protestants And Their Political And Social Engagement (Chapter Six Of Latino Protestants In America: Growing And Diverse), Mark T. Mulder, Aida I. Ramos, Gerardo Marti

Faculty Publications - Department of Sociology

Excerpt: "On a rainy early spring morning in a modest brick Presbyterian church just outside the Fruitvale neighborhood of Oakland, California, sixtyfour worshippers gather. The entire worship is in Spanish. During the sermon, the pastor makes a passing reference to how few of the attenders now live in Oakland proper, that many have to drive farther than ever for church services. The implicit message: the leadership of the church realizes that gentrification of San Francisco has spilled over the Bay Bridge and now threatens the availability of affordable housing throughout Oakland. In response, the congregation has started programs that offer …

The Potential Of Atmospheric Air Cold Plasma For Control Of Bacterial Contaminants Relevant To Cereal Grain Production, Agata Los, Dana Ziuzina, Daniela Boehm, Patrick J. Cullen, Paula Bourke

Articles

The aim of this work was to investigate the efficacy of dielectric barrier discharge atmospheric cold plasma (DBD ACP) against bacteria associated with grains quality and safety. ACP inactivation efficacy was tested against biofilms formed by different strains of E. coli, Bacillus and Lactobacillus in grain model media and against B. atrophaeus endospores either in grain media or attached on abiotic surfaces. Effects were dependent on bacterial strain, media composition and mode of ACP exposure. ACP treatment for 5min reduced E. coli spp., B. subtilis and Lactobacillus spp. biofilms by >3 log10, whereas insignificant reductions were achieved for B. atrophaeus. …

Background: Rates of physical inactivity are high among Black women living in the United States with overweight or obesity, especially those living in the rural South. This study was conducted to determine if an efficacious weight gain prevention intervention increased moderate-vigorous physical activity (MVPA).

Methods: The Shape Program, a weight gain prevention intervention implemented in community health centers in rural North Carolina, was designed for socioeconomically disadvantaged Black women with overweight or obesity. MVPA was measured using accelerometers, and summarized into 1- and 10-min bouts. We employed analyses of covariance (ANCOVA) to assess the relationship between changes in …

A Review Of Early Influences On Physical Activity And Sedentary Behaviors Of Preschool‐Age Children In High‐Income Countries, Ana Cristina Lindsay, Mary L. Greaney, Sherrie F. Wallington, Tatiana Mesa, Carlos F. Salas

Kinesiology Faculty Publications

Purpose: Promoting physical activity (PA) is a key component of preventing and controlling childhood obesity. Despite well‐documented benefits of PA, globally, rates of PA among young children have declined over the past decades, and most children are not accruing sufficient PA daily. Helping children develop the foundation for PA habits early in life is critical for the promotion of health in childhood and prevention of chronic diseases later in life, and will ultimately promote longer and healthier lives for individuals and the general population. The purpose of this review is to provide a synthesis of current evidence on influences …

Assessment Of Ocular Accommodation In Humans, Nicola Szostek

Other Faculty of Health Theses

Accommodation is the change in the dioptric power of the eye altering the focus from distance to near. Presbyopia is the loss of accommodative function that occurs with age. There are many techniques used to measure accommodation, however, there is little consensus as to how clinical data should be collected and analysed. The overarching theme of this thesis is the in vivo examination of accommodation and how lifestyle can affect the onset of presbyopia. An open-field autorefractor with badal adaption was used to examine accommodative dynamic profiles under varying demands of vergence. From this data a new metric for assessing …
