Molecular Regulators Of Post-Golgi Vldl Transport Vesicle (Pg-Vtv) Biogenesis, Aladdin Riad

Electronic Theses and Dissertations

Amongst its numerous functions, the liver is responsible for the synthesis and secretion of very low-density lipoprotein (VLDL). VLDL particles play the important role of facilitating the transport of lipids within the aqueous environment of the plasma; yet high plasma concentrations of these particles result in the pathogenesis of atherosclerosis, while low VLDL secretion from the liver results in hepatic steatosis. VLDL synthesis in the hepatocyte is completed in the Golgi apparatus, which serves as the final site of VLDL maturation prior to its secretion to the bloodstream. The mechanism by which VLDL’s targeted transport to the plasma membrane is …

The Effects Of 6-Weeks Of Resistance Training On The Neuromuscular Fatigue Threshold In Older Adults, Nadia Emerson

PURPOSE: To investigate the effects of 6 weeks of RE on the NMF threshold as well as strength and functional performance in older adults. METHODS: Twenty-four older adults were randomly assigned to 6 weeks of RE (EXE; n = 12; age 72 ± 6.3 y; BMI 28.4 kg/m2 ) or control (CONT; …

Becoming A Food Citizen, Nicole Hornung

Electronic Theses and Dissertations

Environmental citizenship is positioned as a platform where the rights of social and environmental justice converge with civic engagement and responsibility. As industrialized economies continue to exhaust the limits of finite natural resources and exacerbate conditions of global climate change, scholars have questioned if environmental citizenship models offer a method for deepening obligations to a sustainable movement. In the material culture enjoyed by Western civilizations, existing research supports that an individual’s purchases are seen as an indicator of their values and identities. Consequently the commitment to responsible buying behavior or sustainable consumption is in a sense an expression of eco-citizenship. …

An Ethical Justification Of Weight Loss Surgery, Amy Marie Vandyke

Electronic Theses and Dissertations

This dissertation provides an ethical justification of surgical weight loss interventions for the treatment of obesity. Situating obesity as not merely a public health concern but also fundamentally a problem of clinical medicine confronting individual patients and physicians, the dissertation argues that the time frame of public health interventions is too long for individuals presently facing obesity and its deleterious physical and social co-morbidities. It argues that failure to address weight loss on an individual level, and specifically to consider the clinical appropriateness of weight loss surgery (WLS), raises serious questions about failure to respect autonomy and promote patient welfare. …

Biomechanical Comparison Of Lower Limb Unloading Between Common Modalities Of Ankle Foot Orthoses, Andrea Blake Wanamaker

Electronic Theses and Dissertations

Tibial stress fractures and other lower extremity injuries can be treated using an ankle foot orthosis (AFO). AFOs are popular because they allow the patient to ambulate somewhat naturally while reducing weight bearing on the injured limb. Despite their popularity, it is currently unclear how well AFOs reduce lower extremity weight bearing.

The first objective of this investigation was to examine the ability of three commonly used ankle foot orthoses to reduce weight bearing within the lower limb by comparing the ground reaction force measured from a force platform to the force measured from an insole pressure measurement device inside …

Juvenile Ornamentation: Its Evolution, Genetic Basis, And Variation Across Habitats, Angela Tringali

Electronic Theses and Dissertations

Ornamental traits are considered honest advertisements of fitness, and their evolution is usually explained in terms of sexual selection. This explanation remains unsatisfactory in some instances, for example, juvenile birds whose plumage is molted prior to adulthood and breeding. I first evaluate whether juvenile plumage reflectance signals dominance status in the Federally Threatened Florida scrub-jay (Aphelocoma coerulescens) using a combination of observational and experimental methods. Then I estimate the heritability, non-genetic maternal and environmental effects, and strength of selection on juvenile plumage reflectance using archived feather samples and a pedigree constructed from historical nest records. Finally, I compare plumage reflectance …

Major findings of this study support the view that SCCs need more preparation, education and training to increase their competency in preventing and recognizing EHS. Research found that there was no significant difference in scores on the EHS scale based on SCC certification (CSCS vs. SCCC) after accounting for experience, education or division but the …

Evaluation Of A Field Histology Technique And Its Use In Histological Analyses Of Mummified Tissues From Dakhleh Oasis, Egypt, Jennifer Branson

Electronic Theses and Dissertations

Use of paleohistology to identify histological structures in mummified tissues can allow insight into pathological conditions such as parasites, cirrhosis and lung scarring. However, increasing concerns in archaeological sciences include restrictions on removal of human remains from their site of origin for scientific study. In the case of mummified remains, the use of a field paleohistology kit may be deemed useful for ‘point-of-care’ pathological assessment of preserved tissues. This study evaluates field paleohistology protocols for mummified soft tissue based on techniques used modern medical field missions. The application of this technique alleviates the need for export or removal of remains …

The Priming Effects Of Media Frames In Regard To News Images And Stereotypes Held By Hispanic Audiences, Meredith Morris

Electronic Theses and Dissertations

This study applies priming, framing, and exemplification theories to examine the ways in which photos published with a news story influenced readers’ judgments about the ethnicities of the people receiving emergency hunger services. Of particular interest were the perceptions of Caucasian respondents about minorities, and Hispanic perceptions about African Americans and other Hispanics. A sample of 506 college students was randomly assigned to read one of three versions of an online news article about emergency hunger services in Central Florida. One version included two photographs of African American adults receiving food at a food bank. The second version included two …

The Impact Of Voluntary Pre-Kindergarten On The Academic Achievement And Kindergarten Readiness Of Students In A Large Suburban School District, Jordan Rodriguez

Electronic Theses and Dissertations

Throughout the United States, state governments are allocating millions of dollars to support Voluntary Pre-Kindergarten (VPK) programs. Recent research has indicated that students that participate in VPK demonstrate higher academic achievement scores across a number of subject areas. Moreover, VPK participants are more likely to enter primary school on grade level, which in turn leads to a reduction in grade retention. Studies have indicated that although all students that participate in VPK programs benefit from such programs, minority students and students that come from low-socioeconomic backgrounds benefit at an even higher level. The intent of this study was to determine …

Fetal-Pelvic Disproportion And Pelvic Asymmetry As A Potential Cause For High Maternal Mortality In Archaeological Populations, Sarah Stansfield

Electronic Theses and Dissertations

Females of childbearing age are overrepresented in the population of the Kellis 2 cemetery (100-450 AD) in the Dakhleh Oasis, Egypt (Wheeler 2009). The demographic overrepresentation found here may be the result of complications related to childbirth. Clinical literature demonstrates that fetal size is rarely an explanation for failed labor (Cunningham et al. 2001) and the fetuses buried in the Kellis 2 Cemetery at the Dakhleh Oasis were not larger than average (Tocheri et al. 2005), directing the focus to dimensions of the maternal pelvis for evidence of obstetrical issues, such as abnormally compressed pelvises. To formulate a test for …

Interpreting Diet And Nutritional Stress In Napoleon's Grand Army Using Stable Carbon And Nitrogen Isotope Analysis, Sammantha Holder

Electronic Theses and Dissertations

A mass grave containing the remains of at least 3269 Napoleonic soldiers from 1812 was discovered in Vilnius, Lithuania in 2001. Stable carbon and nitrogen isotopic analyses were performed on collagen from 78 femoral samples to explore dietary variation within the sample. Starvation and nutritional distress were also evaluated through the examination of nitrogen enrichment in bone collagen. Clinical studies have demonstrated that enriched nitrogen isotope values can indicate periods of nutritional stress and starvation; however, this is the first study to examine its use as a diagnostic indicator of starvation in a historical population using bone tissue. According to …

Gender Differences And Fast Food Preferences Among U.S. College Students, Donald Persaud

Electronic Theses and Dissertations

The intent of this research is to examine the relationship of corporate fast food and health within the context of gender. It tests the hypothesis that Western perceptions of masculinity and femininity inform a differentiated pattern of food preference, which will correlate with health as measured by Body Mass Index (BMI). The targeted sample population for the study is the undergraduate community of the University of Central Florida, and fast food is a chosen dietary medium because it is an increasingly ubiquitous source of caloric energy in the American foodscape, representative of the mass production model applied to cuisine in …

Effects Of Dissolved Nutrient Ratios And Concentrations On Litter-Associated Microbial Activity In Streamside Channels, Timothy Burns

Electronic Theses and Dissertations

Heterotrophic consumers, such as microorganisms and invertebrates, play a fundamental role in the flow of carbon and energy in streams. The effects of dissolved nutrient concentrations, and especially ratios, on litter—associated microorganisms and decomposition rates of detritus are poorly understood. This study addressed the responses of heterotrophic microbes to a wide range of concentrations and ratios of dissolved inorganic nitrogen (N) and phosphorus (P) in streamside channels simulating headwater streams. Two main questions were: (1) do microbial parameters and litter decomposition rates peak at a dissolved N:P ratio that approaches the nutrient ratio of microbial biomass, and (2) does microbial …
