Sex Differences In Nicotine-Conditioned Hyperactivity In A Model Of Dopamine D2 Receptor Priming: Roles Of Dopamine D2 And D3 Receptor Subtypes., Ashley Brianna Sheppard

Electronic Theses and Dissertations

The aim of this investigation was to determine the effect of a nicotine-conditioned context on locomotor hyperactivity in an animal model of D2-priming, and whether conditioned hyperactivity could be blocked by the D2 antagonist eticlopride or the D3 antagonist nafadotride. D2-primed male rats showed enhanced nicotine sensitization as evidenced by statistically significant differences in horizontal activity. D2-primed female rats administered nicotine demonstrated an increased hypoactive response after initial sensitization and increased stereotypy. Eticlopride and nafadotride blocked sensitization to nicotine in both D2-primed and non D2-primed males and females. Eticlopride blocked conditioned hyperactivity in females but not in males. D2-primed female …

By focusing on the predecessors of Jerry Falwell …

Amphetamine Sensitization And In Vivo Microdialysis Of The Nucleus Accumbens Core Of Adult Male And Female Rats D2-Primed As Neonates., Zackary Adam Cope

Electronic Theses and Dissertations

Neonatal administration of quinpirole produces significant increases in D₂ receptor sensitivity that persists into adulthood. This phenomenon, known as D₂ receptor priming, is consistent with pathology in schizophrenia. Rats were administered quinpirole or saline postnatally and raised to adulthood. In adulthood, rats were administered d-amphetamine sulfate or saline every other day and were placed in a locomotor arena where activity was measured over 7 trials. Results showed that D₂-primed rats receiving amphetamine were higher in locomotor activity across all days of testing compared to other groups. This effect was more prominent in males than in females. …

The Evolution Of Feminine Loyalty Trends In Twentieth And Twenty-First Century Appalachian Literature., Candace Jean Daniel

Electronic Theses and Dissertations

Loyalty to the self, family, and husband create interesting tensions for feminine characters in Appalachian literature. Traditional views of loyalty dictate that the Appalachian woman chooses to be loyal to her husband and family while abandoning her self loyalty. Appalachian women writers define the terms of loyalty and the conflicts these three levels create. Furthermore, studying a progression of novels from 1926 to the present shows that feminine loyalty trends have changed. This argument focuses on examining loyalty trends of feminine Appalachian characters, studying the contentions among those loyalties, specifically showing how loyalty patterns have changed in literature, and offering …

Surveys were given to randomly selected cluster samples of students currently enrolled at the university. These surveys consisted of demographic questions and a scale designed to measure perceptions. Also devised was a scale to measure traits of depression. Both bivariate and multivariate analysis showed that the …

Identification Of Chlamydial Iron-Responsive Proteins During Intracellular Growth., Brian D. Dill

Electronic Theses and Dissertations

Chlamydia trachomatis is an obligate intracellular bacterium and the most prevalent cause of bacterial sexually transmitted disease. Genital chlamydial infections, marked by chronic, intense inflammation, can lead to genital tissue scarring and infertility and is a contributing factor to development of pelvic inflammatory disease and ectopic pregnancy. Iron is required as a cofactor for numerous highly conserved pathways, and nearly all studied organisms rely on iron for growth. In response to iron restriction, the chlamydial developmental cycle arrests at the intracellular reticulate body stage, resulting in a phenomenon termed persistence. Persistence likely plays a role in chlamydial pathogenesis through the …

The Construction Of Airfields During The New Georgia Campaign Of 1943-44: Lessons Learned By The United States Naval Construction Battalions., Joseph Christopher Zimmerman

Electronic Theses and Dissertations

Prevalent depictions of United States Naval Construction Battalions (Seabees) were engendered by John Wayne in The Fighting Seabees and the musical, South Pacific. While capturing the ingenious determination that birthed their motto '˜Can Do', these incomplete pictures don't portray the complexity of construction under combat conditions in a harshly unforgiving and demanding environment.

The Seabee's first combat landing was New Georgia. In six months, these battalions built five airfields, granting Allied forces air superiority over the Solomon Islands and Rabaul. Battalion records stored at the Naval Facilities Command Archives, Port Heuneme, California, combined with documents from the National Archives, …

Erosion And Trail Building: A Case Study Of The East Tennessee State University Trail System., Joshua Callahan

Electronic Theses and Dissertations

Natural and accelerated erosion from trail users affects the sustainability of trail systems. Designing and building sustainable trail systems will greatly decrease the effect that erosion has on a trail. Trails that allow multiple types of users, such as hiking and mountain biking, must be able to sustain both groups. At East Tennessee State University the trail system was originally designed for hiking. Mountain bikers have become the main user group on the trail system leading to erosion problems on certain areas of the trail due to trail design flaws. The study seeks to identify the problem areas of trail …

It is our intention to derive a methodology for which to model discrete paired longitudinal data. Through the use of transition matrices and maximum likelihood estimation techniques by means of software, we develop a way to model the progression of such data. We provide an example by applying this method to the Wisconsin Epidemiological Study of Diabetic Retinopathy data set. The data set is comprised of individuals, all diabetics, who have had their eyes examined for diabetic retinopathy. The eyes are treated as paired data, and we have the results of the examination at the four unequally spaced time points …

Characterization Of Heat Shock Protein A12b As A Novel Angiogenesis Regulator., Rebecca J. Steagall

Electronic Theses and Dissertations

Previously, we cloned Heat shock protein A12B (HspA12B), the newest member of a recently defined subfamily of proteins distantly related to the Hsp70 family that are enriched in atherosclerotic lesions. We have found that HspA12B is predominantly expressed in vascular endothelium, and that it is involved in angiogenesis which we probed by in vitro angiogenesis assays (Matrigel), migration assays and Directed In Vivo Angiogenesis Assay (DIVAA). Hsp70s are molecular chaperones that are inducible by stress and have been found to be anti-apoptotic (Li et al. 2000; Nylandsted et al. 2000; Garrido et al. 2001). Because of its homology to Hsp70, …

Mercury Emissions From Coal-Fired Power Plants : A Local Or A Global Pollutant?, Paul Franklin Tirey 1961-

Electronic Theses and Dissertations

This dissertation tests whether or not mercury emissions from electric power plants are not a significant contributor to mercury measurements in rainfall and argues that the current United States (U.S.) Environmental Protection Agency (EPA) proposed regulatory scheme for controlling mercury from electric power plants, the Clean Air Mercury Rule (CAMR), is an effective regulatory mechanism by using a number of ordinary least square (OLS) and spatial regression models. Two dependent variables are tested, mercury concentration (the average mercury concentration measured in rainfall in nanograms per liter, ng/L) and mercury deposition (the total annual mercury falling at each measurement site in …

This study utilized the standardized California Critical Thinking Skills Test (CCTST) Form 2000 to measure students' pretest and post test critical thinking abilities prior to and upon completion of a critical thinking infused curriculum. In addition, the researcher also tested a predictor model for students' entry level critical thinking skills, as well as two separate predictor models for students' acquired critical thinking skills. The researcher not only tested each of the models using the total scores, but also for the subscales of analytic, inference, evaluation, deductive and inductive. A paired samples t test indicated there were no significant differences between …

Clustered Longitudinal Data Analysis., Ming Wang

Electronic Theses and Dissertations

Clustered longitudinal data is often collected as repeated measurements on subjects over time arising in the clusters. Examples include longitudinal community intervention studies, or family studies with repeated measures on each member. Meanwhile, cluster size is sometime informative, which means that the risk for the outcomes is related to the cluster size. Under this situation, generalized estimating equations (GEE) will lead to invalid inferences because GEE assumes that the cluster size is non-informative. In this study, we investigated the performances of generalized estimating equations (GEE), cluster-weighted generalized estimating equations (CWGEE), and within-cluster resampling (WCR) on clustered longitudinal data. Based on …

Evaluation Of Bone Quality Using Novel Image Analyses And Mechanical Testing Methods., Qian Xu

Electronic Theses and Dissertations

Osteoporosis has become a growing health threat with rising social and economic consequences. The understanding of the relationship between bone mechanical strength and bone structural quality is important for the diagnosis of osteoporosis and the evaluation of osteoporosis treatments. A novel cancellous bone segmentation method was developed to separate cancellous bone from cortical bone automatically. The segmentation was based on the three-dimensional images. The basic idea of the method is that a contiguous three-dimensional non-bone region that is located inside the whole bone region of interest can be defined as the marrow region. Any bone material that is surrounded by …

Disappointment Domains, Quality Of Life, And The Impact Of Mental Illness : An Evaluation Of Demographic Differences., Christina Lynn Adkins

Electronic Theses and Dissertations

The concept of quality of life (QOL) has been the topic of many research projects, yet several clinically relevant aspects of this concept have been overlooked. Specifically, few studies have addressed the impact of such demographic variables as race and sex on the life domains that have been particularly disappointing to patients with mental illnesses. The current research project aims to contribute to the understanding of the impact these variables have on quality of life, specifically addressing the following hypotheses: (1) Domains of disappointment will vary according to race and sex; (2) Race and sex will interact to predict which …

Computational Analysis Of Expressed Sequence Tags For Understanding Gene Regulation., I. Elizabeth Cha 1973-

Electronic Theses and Dissertations

High-throughput sequencing has provided a myriad of genetic data for thousands of organisms. Computational analysis of one data type, expressed sequence tags (ESTs) yields insight into gene expression, alternative splicing, tissue specificity gene functionality and the detection and differentiation of pseudogenes. Two computational methods have been developed to analyze alternative splicing events and to detect and characterize pseudogenes using ESTs. A case study of rat phosphodiesterase 4 (PDE4) genes yielded more than twenty-five previously unreported isoforms. These were experimentally verified through wet lab collaboration and found to be tissue specific. In addition, thirteen cytochrome-like gene and pseudogene sequences from the …

Electronic Theses and Dissertations

The number of refugees being uprooted from their homes to seek refuge and resettlement in countries like the United States continues to grow, with large numbers being children. While each refugee group has its own set of challenges when adjusting to a new country, a better understanding of their needs may help facilitate their transition more quickly with lesser challenges. This study investigated the adjustment of one such group--Somali Bantus in a Midwestern U.S. city. Specifically, acculturation and school adaptation of Somali Bantu refugee children was explored using the Differentiated Multidimensional Model of Acculturation. Somali Bantu refugee children in 5 …

A Possible Role For Spla2 In Oligodendrocyte Death And Spinal Cord Injury., William Lee Titsworth

Electronic Theses and Dissertations

Spinal cord injury (SCI) can be divided into two distinct stages, an initial mechanical impact and a later "secondary injury" resulting from a cascade of cytokines triggering a spreading demyelination and apoptosis of neurons and glia within the spinal cord. It is believed that blockade of this "secondary injury" could improve functional and histological recovery following SCI. Here we propose that sPLA2 might be one of the crucial mediators of the secondary injury. To test this possibility we first elucidated that the mRNA and protein of several isozymes of sPLA2 are present in the rodent spinal cord and that the …
