Correlation Of Physicochemical Properties Of Chondroitin Sulfate To Its In-Vitro Absorption And Anti-Inflammatory Activity, Lahari Surapaneni

All Dissertations

The purpose of this study was to investigate if the molecular weight and degree of sulfation of chondroitin sulfate (CS) has an impact on its in vitro absorption and anti-inflammatory activity.
For absorption studies, Caco-2 cells were incubated with eight CS samples of differing molecular weights (7 kDa - 35 kDa). The amount of CS transported into the basolateral side of the Caco-2 monolayer was quantitatively determined to calculate the permeability coefficients (Peff). The permeability coefficients of the eight different CS samples across Caco-2 cell monolayers were assessed. For anti-inflammatory studies, RAW 264.7 murine macrophage cells were pre incubated with …

The state of healthcare in the United States is changing. Amidst this change, there is a debate as to whether health is a public good or if health is a private matter. This change and debate challenges health professionals to rethink the way we go about planning health interventions to better address the many public health issues looming the general population today. The recent rise of obesity and at-risk weight in the United States is a major epidemic that has yet to be resolved. There are many approaches to addressing weight management and for many, public health campaigns have not …

Influence Of Compost Particle Size On Pathogen Survival Under Greenhouse Condition, Junshu Diao

All Theses

The number of foodborne pathogen outbreaks related to fresh produce has increased significantly in recent decades. Animal waste directly applied to agricultural field is one of the possible contamination sources for fresh produce. Composting is one of the recommended means for waste treatments to eliminate or reduce pathogens in manure on farms. Although pathogens can be eliminated by proper composting process, pathogens are able to survive, recolonize and regrow on compost heap surfaces under certain conditions. Due to the outdoor nature of composting process, bioaerosols with different particle sizes can be generated on compost surfaces which can carry pathogens, travel …

Effect Of Forage Type And Corn Supplementation On Animal Performance And Meat Quality, Asher Wright

All Theses

Angus x Hereford steers (441 ± 24 kg; n = 32) were used in a 2-yr study (2011 and 2012) to examine forage type (legume species, alfalfa and soybeans LG vs. grass species, tall fescue and sudangrass, GR) and daily corn supplementation (0%, NS, vs. 0.75% BW, CS) on animal performance and carcass quality. Steers grazed (May-August) for a total of 98 d and 105 d in 2011 and 2012 respectively. Upon completion of the finishing period, steers were slaughtered and carcass data were collected. Steaks (2.5 cm thick) from the longissimus dorsi muscle (LM) were collected for measurement of …

The Effect Of Applying Established Color Theory To Packaging When Visible Product And External Labels Exist Simultaneously, Rachel Randall

All Theses

Color is affected by what is around it. A color doesn't necessarily look the same when its placed against two different colored backgrounds (Ryan, William, and Theodore Conover, 2004) Oftentimes, designers are given a blank package and given the task of creating a label or package for the product. What is missing is the product, which can be an integral part of this design process. What is not yet to be determined by current packaging research is how colors work together through the product and package. One way to determine this would be through transparent bottled packages that contain external …

Food Handling, Hygiene, And Sanitation Practices In The Child-Care Environment In North Carolina And South Carolina, Xi Chen

All Theses

Introduction: Children between the ages of 37 and 54 months enrolled in child-care facilities (CCFs) are reported to be 2.3 to 3.5 times more likely to experience an acute gastrointestinal illness (AGI) than are children cared for in their own home. Identifying potential risk factors for the transmission of enteric pathogens in CCFs is essential to the prevention of AGI.
Methods: A convenience sample of CCFs in North Carolina and South Carolina was recruited to participate in this study. A survey was administered to all CCF directors to collect information about facility characteristics, meal preparation, staff training, hygiene policies and …

Cultivating America's Working Lands: A Study Of The Sociocultural Value Of Family Farms, Katherine Lloyd

All Theses

Our ability to produce food in a sustainable, healthy and humane manner is threatened, both in the United States and on the global scale. This difficulty is exacerbated by expected population growth, creating a need for 60% more food worldwide by 2050 to feed a population of 9.3 billion (United Nations Chronicle, 2012). How we produce food affects local economies, the cultural vitality of communities, and the health of regional ecosystems. Industrial or conventional agriculture is damaging all three of these systems, by draining local economies through corporate business practices, isolating farmers and attributing to rural population losses, while depleting …

Exploring Doctoral Student Experiences From The Perspectives Of Mid-Career Professionals In Educational Leadership Using Photo-Elicitation, Kenyae L. Reese

All Dissertations

Recent literature cites a growing population of students who wait several years post-baccalaureate and into their careers before entering a PhD program. Such population includes doctoral students in education. Despite repeated calls from scholars of higher education, few empirical studies investigate mid-career students’ experiences in doctoral programs. Existing literature consists of anecdotal reports, demographic accounts in which mid-career is a data point among many variables, or empirical studies of international students. Theoretical models describing student experiences of mid-career professionals in doctoral programs are particularly absent. A handful of studies have explored doctoral student experiences of mid-career professionals through traditional interviewing …

Analysis Of The Interaction Of Francisella Tularensis Lvs And Legionella Pneumophila Biofilms With Components Of The Aquatic Environment, Uma Mahajan

Predicting Complex Phenotype-Genotype Relationships In Grasses: A Systems Genetics Approach, Stephen Ficklin

All Dissertations

It is becoming increasingly urgent to identify and understand the mechanisms underlying complex traits. Expected increases in the human population coupled with climate change make this especially urgent for grasses in the Poaceae family because these serve as major staples of the human and livestock diets worldwide. In particular, Oryza sativa (rice), Triticum spp. (wheat), Zea mays (maize), and Saccharum spp. (sugarcane) are among the top agricultural commodities. Molecular marker tools such as linkage-based Quantitative Trait Loci (QTL) mapping, Genome-Wide Association Studies (GWAS), Multiple Marker Assisted Selection (MMAS), and Genome Selection (GS) techniques offer promise for understanding the mechanisms behind …

Attaining Sustainable Behavior Among Non-Environmentally-Motivated Individuals: A Formative Experiment, Brooklynn Wynveen

All Dissertations

Experts agree that overconsumption is a major problem in Western culture today, particularly in the United States. Thus, it is important to promote sustainable behavior among the general public. And yet, existing educational programming geared toward promoting such behavior changes remains appealing largely to environmentally-motivated audiences, as opposed to individuals with alternative (i.e., social and economic) motivations. In response to this discrepancy, I conducted a formative experiment with the goals of: 1) fostering participation among non-environmentally-motivated individuals in sustainable living educational programming; and 2) obtaining behavior change commitments, in the direction of more sustainable lifestyles, from those participants.
As part …

Integrating Biomechanics And Cell Physiology To Understanding Ivd Nutrition And Cell Homeostasis, Yongren Wu

All Dissertations

Back pain associated with degeneration of the intervertebral disc (IVD) is a major public health problem in Western industrialized societies. Degeneration of the IVD changes the osmotic and nutrient environment in the extracellular matrix (ECM) which affects cell behaviors, including: cell proliferation, cell energy metabolism, and matrix synthesis. In addition, a thin layer of hyaline cartilaginous end-plate (CEP) at the superior/inferior disc-vertebral interface was found to play an important role in nutrient supply as well as load distribution in the IVD. Therefore, our general hypothesis is that the CEP regulates the ECM osmotic and nutrient environment which further affects IVD …

Group Testing Models With Unknown Link Function, Dewei Wang, Karunarathna B. Kulasekera, Colin M. Gallagher, Christopher S. Mcmahan

Graduate Research and Discovery Symposium (GRADS)

Group testing through the use of pooling has proven to be an efficient method of reducing the time and cost associated with screening for a binary characteristic of interest such as infection status. A topic of key interest in this area involves the development of regression models that relate the individual level covariates to the binary pool testing responses. The research in this area has primarily focused on parametric regression models. In this poster, we will introduce a new estimation method which can handle multi-dimensional covariates while assuming the link is unknown. The asymptotic properties of our estimators are also …

The Invasive "Kudzu Bug," Megacopta Cribraria (Hemiptera: Plataspidae) As An Agricultural And Nuisance Pest, N. J. Seiter, J. K. Greene, F. Reay-Jones, E. P. Benson, P. A. Zungoli

Graduate Research and Discovery Symposium (GRADS)

The invasive “kudzu bug,” Megacopta cribraria (Hemiptera: Plataspidae) is a native of Asia that was found in northeastern Georgia in fall 2009. This insect has since spread rapidly throughout the southeastern U.S., and is abundant in much of South Carolina. Megacopta cribraria feed on the vascular fluid of several legumes, primarily kudzu, Puereria montana var. lobata, and soybeans, Glycine max. These insects enter soybean fields in often alarming numbers, leaving conspicuous lesions on soybean stems and potentially reducing yields. In addition, M. cribraria congregate on homes and other structures in late fall as they seek overwintering sites, potentially becoming a …

The Value Of Relevant, Project-Based Learning To Youth Development, Kerry Schwartz, Darcy Tessman, Daniel Mcdonald

Journal of Youth Development

Project Based Learning models present authentic learning opportunities with real-life situations, enabling students to set their own learning goals and forge their own relationships (Barab, et al., 2001). The autonomy inherent in this model allows youth to bring their skills and experiences to real situations and to be seen as valued community members. This article describes a project-based learning model involving “externs,” who developed and implemented sustainability projects in their communities. Externs worked with Cooperative Extension professionals on locally relevant community projects during the summer of 2011 in three Arizona counties. The project based learning experience had a positive impact …

How Clean Is A Restaurant Menu? A Study Of Bacterial Transfer To And From Restaurant Menus , Ibtehal Alsallaiy, Paul Dawson, Inyee Han

Graduate Research and Discovery Symposium (GRADS)

Some non-food contact surfaces such as restaurant menus are not routinely evaluated for microbial contamination thus can be a potential contamination risk. The main objectives of this study were to detect bacteria on restaurant menus, test the rate of bacteria transfer from menus to consumers and determine the survival rate of bacteria on the menu surface. Samples collected from local restaurants’ menus and analyzed for total aerobic organisms and Staphylococcus spp, indicated that menus often harbored detectable levels of bacteria. The average transfer rate was 11.17%, with a high variability between subjects (10.45% standard deviation). Survival rate of bacteria was …
