Certified Personal Trainers And Physicians: An Evaluation Of Consumer Preference, Influence, And Decision Making On Intent To Use A Weight-Loss Medication, Linda Lemgruber Lobb

Electronic Theses and Dissertations

In health-related behavioral decision-making, the Theory of Planned Behavior (TPB) posits that attitudes toward a behavior are the function of three metrics: beliefs and strengths of beliefs toward the behavior, subjective norms around the behavior and locus of control for the individual (Ajzen, 1988). The purpose of this research was to identify the extent to which consumers would accept the recommendation of taking weight-loss medications, based on the source of the recommendation. Research shows that the source of knowledge for information plays a significant role in health-related decision-making of consumers (Pornpitakpan, 2004). In comparison to traditional weight-loss methods such as …

The Role Of Religion In The Relationship Between Loneliness And Health Behaviors, Lindsy Jean Magee

Electronic Theses and Dissertations

While research has demonstrated the relationship of religion to health risk and health promoting behaviors, it has not investigated the relationship between religious coping and health risk and health promoting behaviors. In addition, while the link between loneliness and certain health risk and health promoting behaviors has been established, little research has looked at the potential effect that religion has on the relationship between loneliness, health risk, and health promoting behaviors. As such, it was the purpose of this study to investigate the relationship between religious coping and health risk and health promoting behaviors and to investigate the role of …

The Efficacy Of Prostaglandin Synthase Inhibition On Attenuating Pressure Overload Induced Cardiac Remodeling, Krishna T. Nagalla

Electronic Theses and Dissertations

Chronic hypertension has long been known to cause left ventricular remodeling. Although previous studies pointed towards inflammation as the pathological driver of cardiac remodeling, the exact mechanistic pathway associated with pressure overload-induced cardiac remodeling remains to be elucidated. In order to address this issue, we designed this study to determine pathways associated with pressure overload induced cardiac remodeling and identify therapeutic targets to attenuate this maladaptive cardiac remodeling. Rats with surgically constricted abdominal aorta were used as an animal model for pressure overload and associated Left ventricular (LV) structure and functional changes were measured by pressure-volume admittance catheterization. Human cardiac …

Characterization Of Prolylcarboxypeptidase Expression Pattern In Rat Cardiomyocytes In Nutrition Overload Conditions, Tahmineh Tabrizian

Electronic Theses and Dissertations

Prolylcarboxypeptidase (PRCP) is a serine protease that cleaves the last amino acid at the carboxy-terminus of peptides with a penultimate proline such as angiotensin II (Ang II), angiotensin III (Ang III), prekallikrein (PK) and α-melanocyte-stimulating-hormone (1-13) (α-MSH1-13). By inactivating Ang II and Ang III, PRCP promotes vasodilation and insulin sensitivity. As well by activating PK, PRCP increases nitric oxide (NO) generation and vasorelaxation through bradykinin (BK) liberation from high molecular weight kininogen (HK). PK is activated to kallikrein by PRCP, implicating a role for PRCP in the coagulation pathway. The resultant kallikrein will activate FXII which in a reciprocal manner …

Secondary Metabolite Production By An Endophytic Bacillus Sp. From Platanus Occidentalis, Michael C. James

Electronic Theses and Dissertations

Endophytes are bacterial and fungal microbes that live inside of plant tissue without causing disease. Endophytes have applications in many industries including the pharmaceutical and food industries as producers of natural products. This potential was demonstrated by investigating the natural product production from a Bacillus amyloliquefaciens endophyte of Platanus occidentalis using a combination of MALDI-IMS, LC-MS, MS-MS, and NMR methods, by purifying nicotianamine from soy flour, and by reviewing natural product inhibitors of the hepatitis C virus (HCV). The secondary metabolite production of the endophytic B. amyloliquefaciens was investigated under a variety of fermentation conditions. It was discovered that the …

Obesity Related Perturbations On Cardiovascular, Immune And Endocrine Response To Active And Passive Stress, Ashley Elizabeth Burch

Electronic Theses and Dissertations

As the obesity epidemic increases, the prevalence of obesity-related diseases grows simultaneously. The internal environment of chronic low-grade inflammation, which characterizes obesity, leaves individuals vulnerable to disease. Cardiovascular dysfunction represents a consequential effect of obesity. An early indicator of cardiovascular disease is an impaired stress response. Further, the type of stress (active versus passive) may be differentially affected representing additional distinctions in impairment. In the present study, we have used two types of stress (active and passive) to investigate obesity-instigated alterations in cardiovascular, immune and endocrine response to stress. In addition, we have evaluated how these systems may overlap to …

Movements, Fishery Interactions, And Unusual Mortalities Of Bottlenose Dolphins, Steven Shippee

Electronic Theses and Dissertations

Bottlenose dolphins inhabiting coastlines and estuaries in Florida have been impacted in the past decade by development, algal blooms, catastrophic pollution, and fishery interactions (FI). Dolphins react to disturbance and environmental stressors by modifying their movements and habitat use, which may put them in jeopardy of conflict with humans. FI plays an increasing role in contributing to dolphin mortalities. I investigated dolphin movements, habitat use, residency patterns, and frequency of FI with sport fishing. Tagging studies with short-term data tags and bolt on radio-transmitters were done in several locations in Florida and the east coast providing fine-scale measurements of swimming, …

Mothers' Temperament And Personality: Their Roles In Parenting Behaviors, Parent Locus Of Control, And The Outcomes Of Young Children, Jayme Puff

Electronic Theses and Dissertations

Many researchers have used the terms 'temperament' and 'personality' interchangeably when describing parents' behavioral styles. Although individual relationships among parents' temperament and personality, parenting behaviors, other parent characteristics, and young children's outcomes have been documented in the literature, parents' temperament and personality have not been examined collectively in conjunction with parenting and child outcome variables. As part of this study, 214 culturally diverse mothers with young children who ranged in age from 2- to 6-years rated their own temperament and personality, their parenting characteristics, and their young child's functioning (i.e., temperament and emotional and behavioral functioning). When examining mothers' temperament …

Antecedents And Consequences Of Customer Experience In Beverage Establishments, Milos Bujisic

Electronic Theses and Dissertations

It is estimated that there are approximately 42,000 beverage establishments in the U.S. whose annual revenue surpasses $20 billion (First Research, 2014). To facilitate discussion of beverage establishments, it is essential to recognize beverage establishments as businesses whose majority of sales come from alcoholic drinks (Moss, 2010a). In this research, beverage establishments are divided into beverage-only bars, bar/entertainment combinations, and food and beverage combinations. Even though they are a well-established industry, beverage establishments have received little academic attention (Moss, 2010b). For example, previous studies have given little attention to the development of the model that examines the relationships between quality …

A Time-Course Analysis Of Behavioral Plasticity And Differential Gene Expression Patterns In Response To Density In Schistocerca Americana (Orthoptera: Acrididae), Steven Gotham

Electronic Theses and Dissertations

Phenotypic plasticity is the ability of the genotype to express alternative phenotypes in response to different environmental conditions and this is considered to be an adaptation in which a species can survive and persist in a rapidly changing environment. Some grasshoppers and locusts are capable of expressing an extreme form of density-dependent phenotypic plasticity, known as locust phase polyphenism. At low population density, the individuals typically have a cryptic coloration as nymphs, are less active, and only seek out conspecifics for reproductive purposes. At high density, however, they develop a drastically different phenotype in which they have a conspicuous coloration, …

Chemical Differentiation Of Human Osseous, Non-Human Osseous, And Non-Osseous Materials Using Scanning Electron Microscopy - Energy Dispersive X-Ray Spectrometry (Sem/Edx) And Multivariate Statistical Analysis, Cayli Meizel-Lambert

Electronic Theses and Dissertations

Identification of osseous materials is generally established on gross anatomical factors; however, highly fragmented or taphonomically altered materials are often problematic and alternative methods, such as biological, histological, or chemical analysis, must be utilized. Recently, chemical methods have been proposed to sort unknown materials according to their Ca/P ratios. Ubelaker and colleagues (2002) proposed using SEM/EDX to achieve this distinction and Christensen and colleagues (2012) have validated X-ray Fluorescence Spectrometry (XRF) for this application. An alternative method of analysis involves performing principal component analysis (PCA) on element spectra to classify unknown materials based on their trace element composition. Zimmerman (2013) …

Synthesis Of Resveratrol Ester Derivatives, Daniel Ressler

Electronic Theses and Dissertations

The goal of this research project was to synthesize derivatives of transresveratrol. In order for resveratrol to be activated and used by the body it needs to bind to Human Serum Albumin (HSA), a protein in blood plasma. The derivatives were synthesized to improve the ability of resveratrol to enter cells as well as improve their ability to bind to HSA. The three derivatives that were synthesized have converted one of the hydroxyl groups on resveratrol to an ether with a methylene chain terminated by a carboxylic acid. By varying the lengths of the methylene chain we varied the water …

Identification And Characterization Of Genetic Factors Involved In Candida-Bacterial Interactions, Sean J. Fox

Electronic Theses and Dissertations

Throughout existence, fungi and bacteria have long shared ecological niches and thus engage in numerous interactions to mutually enhance survival or antagonistically gain competitive advantages. Of importance to human health are those interactions that involve bacteria with the opportunistic fungi, Candida albicans. An important virulence factor of C. albicans is the ability to control morphology, which allows the transition between yeast, pseudohyphal, and hyphal phenotypes. Morphological control in C. albicans is governed by quorum sensing and the secreted autoregulatory molecule farnesol. Quorum sensing allows individual cells to sense the environment and respond as a group. Bacteria also use quorum …
