Attentional Bias Toward Pain-Related Pictorial Stimuli Among Individuals With Migraine Following Negative Mood Induction, Michael James Mcdermott

Electronic Theses and Dissertations

Migraine is associated with significant reductions in daily functioning and quality of life and is the 19th largest cause of disability globally. The fear-avoidance model of chronic pain details potential pathways for the development of pain disability and affective distress and provides a platform for understanding the dynamic relationship between psychological factors and migraine. Consistent with the fear-avoidance model, a growing body of research provides support for the role of selective attentional biases toward threat-related stimuli among chronic pain patients. However, the few studies to examine the role of selective attentional biases in migraine demonstrate mixed findings, and the exact …

Siblings Of Children With Long Qt Syndrome: Relationships And Coping, Courtney Mccuen-Wurst Ms, Lcsw

PCOM Psychology Dissertations

Long QT syndrome (LQTS) is a congenital heart disorder, usually diagnosed in childhood, that may lead to cardiac arrest, seizures, syncope, and sudden death. The birth of a child with LQTS, as well as the social, physical, and psychological functioning of the affected child, can have a significant impact on the family. The family stress associated with having a child with any disability or chronic illness is likely to affect the lives of siblings. The lack of research on the effects of having a sibling with long QT syndrome on individuals who do not have LQTS provided the rationale for …

The Development And Tryout Of A Program Designed To Increase Students' Multiplication Fact Fluency, Linton D. Williams

PCOM Psychology Dissertations

Fluency skills are fundamental to the ability to complete relatively more complex problems using less mental energy. Most math curriculums do not stress the importance of automaticity of math facts. Variations in teaching styles and teaching modality seem to negate the true purpose for cementing and rapidly retrieving math facts. This study put to the test a program that was designed to increase students’ ability to retrieve multiplication facts fluently. The program exercised cognitive structures and enabled students to retrieve multiplication facts quickly. The results of a matched-pairs t-test indicated that after the students completed the course of the program, …

Cross-Talk Between The Tumor Suppressors Par-4 And P53, Tripti Shrestha Bhattarai

Theses and Dissertations--Toxicology and Cancer Biology

This work describes the fascinating interplay between two tumor suppressors Prostate apoptosis response-4 (Par-4) and p53. The guardian of the genome, p53, is frequently mutated in human cancers, and may contribute to therapeutic resistance. However, p53 is intact and functional in normal tissues, and we observed that specific activation of p53 in normal fibroblasts could induce apoptosis selectively in p53-deficient cancer cells. This paracrine apoptotic effect was executed by Par-4 secreted in response to p53 activation. Accordingly, activation of p53 in wild-type mice, but not in p53^-/- or Par-4^-/- mice, caused systemic elevation of Par-4 that induced apoptosis …

Salmonellosis In Kentucky Cattle - 2003-2014, Azia Elizabeth Ramirez

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

The group of bacteria known collectively as Salmonella has historically been a major cause of both health and economic hardships. In particular, Salmonella in bovine has been estimated to cause the economy to lose billions of dollars annually, both due to the increased morbidity and mortality rates of the cattle themselves and the indirect loss of potential profits, and also results in the spread of the bacteria to humans to ill effect. Salmonella thus can be quite taxing to agricultural communities, the animals upon which they rely, and the consumers that buy said communities’ commodities. Thus, the importance of an …

Overexpression Of Human Cu/Zn Superoxide Dismutase In Mice; The Effect Of Increase Superoxide Scavenging On Autonomic Control Of The Heart., Jeffrey Hatcher

Electronic Theses and Dissertations

Dysregulation of the autonomic cardiovascular control is a complication of diseases including diabetes, hypertension, sleep apnea, and aging. A common factor in these conditions is an increase in reactive oxygen species (ROS) in neural, cardiac, and endothelial tissues. Cu/Zn superoxide dismutase (SOD1) is an intracellular anti-oxidant enzyme that catalyzes dismutation of the superoxide anion (O2.-) to hydrogen peroxide (H2O2). Expression and function of this enzyme are diminished in pathologies that impair cardiovascular autonomic control. This study employed mice overexpressing a transgene for human SOD1 (hSOD1) to determine if its overexpression would alter autonomic regulation of BP, HR, and BRS in …

Alcohol Consumption, Frailty, And The Mediating Role Of C-Reactive Protein In Older Adults, Mona Shah

Electronic Theses and Dissertations

Frailty is a well-established indicator of late-life decline and is accompanied by higher rates of comorbidity and disability. Meanwhile, an estimated 41% of adults over the age of 65 report consuming alcohol – an identified health risk and protective factor depending on dosage. Given that the demographic group of older Americans is projected to double by the year 2050, identification of frailty risk and protective factors is imperative. The goals of this thesis are to: (1) identify how varying levels of alcohol consumption relate to frailty, and (2) elucidate a possible mechanism that accounts for the relationship between alcohol consumption …

Viscoelastic Effects On Electrokinetic Particle Focusing In A Constricted Microchannel, Xinyu Lu, John Dubose, Sang Woo Joo, Shizhi Qian, Xiangchun Xuan

Mechanical & Aerospace Engineering Faculty Publications

Focusing suspended particles in a fluid into a single file is often necessary prior to continuous-flow detection, analysis, and separation. Electrokinetic particle focusing has been demonstrated in constricted microchannels by the use of the constriction-induced dielectrophoresis. However, previous studies on this subject have been limited to Newtonian fluids only. We report in this paper an experimental investigation of the viscoelastic effects on electrokinetic particle focusing in non-Newtonian polyethylene oxide solutions through a constricted microchannel. The width of the focused particle stream is found NOT to decrease with the increase in DC electric field, which is different from that in Newtonian …

Development Of A Nano-Sensing Approach And A Portable Prototype For Real-Time Detection And Quantification Of Free Mercury In Stream-Flow: Combining Science And Engineering In Pro Of The Environment, Warinya Chemnasiri

Electronic Theses and Dissertations

Mercury (Hg) is a well-known hazardous environmental contaminant existing in several forms, but all are toxic to human in one way or the others. Since Hg usually settles into water polluting the environment and accumulating in living organisms, it is crucial to monitor Hg levels in the aquatic ecosystem. Although there are many well established techniques currently used to detect Hg, most of them require elaborate and time-consuming sample preparation and pre-concentration procedures, as well as costly and bulky equipment that limit their practical application in the field. In order to overcome the existent limitations in Hg determination methods, Hernandez …

Exploring Social Identity Through Stable Isotope Analysis In The Kellis 2 Cemetery, Kaitlin East

Electronic Theses and Dissertations

The material remains of ancient Egypt provide extensive and wide ranging data about the empire throughout its history. However, little evidence is available from ancient Egypt, or any past culture, with which to rebuild an image of social identity or individual experiences. This is especially problematic when the dominant narrative ignores experiences of minorities and minimizes the variation existing throughout the empire. Stable isotope analysis has the potential to reveal variability in lived experience of past peoples by acting as a proxy for behavior that can be analyzed from bone. Such an approach has been applied on individuals from the …

Water Quality Trading From The Point Source Perspective: Willingness To Pay For Abatement Credits And Preferences For Water Quality Trading Market Mechanism, Andrew Mclaughlin

Theses and Dissertations--Agricultural Economics

As part of the EPA’s initiative to reduce the hypoxic zone in the Gulf of Mexico, a feasibility study for a potential water quality trading (WQT) program in the Kentucky River Watershed (KRW) was conducted. While theoretically, emission trading programs are among the most efficient means of reducing pollution, empirical evidence suggests low-trade volume as a primary concern for the long-term success of such programs. Some of the important reasons for the low volume of trade are due to lack of suitable market trading mechanism for point sources and lack of information on willingness to pay (WTP) for abatement credits. …
