Rx Plays Multiple Roles In Eye Development, Vera A. Voronina Aug 2003

Rx Plays Multiple Roles In Eye Development, Vera A. Voronina

Graduate Theses, Dissertations, and Problem Reports (ETD)

The homeobox was first identified as a common feature of Drosophila genes that control pattern formation during embryogenesis. These genes have been implicated in the regional specialization of the developing brain, spinal cord and other body structures. Homeobox gene families are highly conserved and encode DNA-binding regulatory proteins. Certain members of the homeobox gene family, including Pax6, Chx10, Lhx2, Otx2, Six3 and Six6, are crucial for development of the eye. A new family of retinal homeobox genes, Rx, is expressed early in embryogenesis in retinal stem cells. This expression pattern, along with results of overexpression and gene deletion studies, is …

Bone Fracture Toughness Of Estrogen Deficient Rabbits, Matthew S. Smith Aug 2003

Bone Fracture Toughness Of Estrogen Deficient Rabbits, Matthew S. Smith

Graduate Theses, Dissertations, and Problem Reports (ETD)

Bone mass is commonly used as an indicator of fracture risk. It has been shown in numerous studies that bone loss causes increased bone fragility and risk of fracture. It has also been shown that 50% of patients with osteoporotic vertebral compression fractures have the same bone mass as normal age matched controls. Thus, bone mass alone is not the only indicator of bone quality and ability to resist fracture.;The objective of this study was to qualitatively assess bone's mechanical and histomorphometric changes with drug treatment, and estrogen deficiency, using fracture toughness, femoral neck fracture and histomorphometric analysis in an …

Genetic, Metabolic, And Histopathological Studies Of Particle -Associated Respiratory Alterations, Mohamed Mohamedy Ghanem

Graduate Theses, Dissertations, and Problem Reports (ETD)

Cytochrome P450s (CYPs) form a superfamily of enzymes crucial for the oxidative metabolism of a wide variety of endogenous and exogenous (xenobiotic) compounds. Cytochrome P4501A1 (CYP1A1) is a member of the CYP1A subfamily that is involved in pulmonary carcinogenesis. CYP1A1 metabolizes polycyclic aromatic hydrocarbons (PAH), such as benzo[a]pyrene in cigarette smoke into DNA-binding reactive metabolites resulting in gene mutation and carcinogenesis. Silicosis and coal workers' pneumoconiosis (CWP) are two pulmonary diseases associated with occupational exposure to silica and coal dust (CD), respectively. Most coal miners are smokers or ex-smokers and epidemiologic studies of coal dust carcinogenesis are confounded by the …

Cytogenetic Analysis Of Primary Breast Tumors And Mcf10a Cells To Determine Early Steps Of Breast Carcinoma, Mohammad Mah Odetallah

Graduate Theses, Dissertations, and Problem Reports (ETD)

Breast cancers are characterized by genomic instability, abnormal chromosomal counts and multiple translocations. There is a heavy burden on tumor cells to acquire as many mutations as possible in a short time. Tumors seem to achieve that through genomic instability. The role of homologous recombinational repair loss has been well established as a mechanism of chromosomal instability. A researcher at the University of Pittsburgh, Dr. Jean Latimer, was able to demonstrate the loss of nucleotide excision repair (NER), in adjacent non tumor tissue. NER functions in bulky adducts repair, following UV radiation. These lesions introduce a bend in the DNA …


Uterine Uptake Of Diazepam And Quantification By Gas Chromatography/Mass Spectrometry, Steven Scott Wolfe May 2003

Uterine Uptake Of Diazepam And Quantification By Gas Chromatography/Mass Spectrometry, Steven Scott Wolfe

Graduate Theses, Dissertations, and Problem Reports (ETD)

One of the difficulties in drug delivery is transporting the compound of interest to the target organ while minimizing exposure to the rest of the body. Intravenous administration is effective in the delivery of drugs and results in high bioavailability leading to very rapid systemic distribution. Oral dosing of drugs is the most popular route because of its ease of administration, but it is subject to first pass metabolism by the liver which can greatly reduce the bioavailability of the parent compound. Patients undergoing hysterectomy were recruited for a study in which they were anesthetized and 5 mg of diazepam …

The third cohort (control cohort) did not consume chemopreventive tamoxifen and underwent mammography screening at real-world rates. The study also assessed the proportion of women in the West Virginia Medicaid …


Ida B. Wells, Catherine Impey, And Trans -Atlantic Dimensions Of The Nineteenth-Century Anti-Lynching Movement, Brucella Wiggins Jordan May 2003

Ida B. Wells, Catherine Impey, And Trans -Atlantic Dimensions Of The Nineteenth-Century Anti-Lynching Movement, Brucella Wiggins Jordan

Graduate Theses, Dissertations, and Problem Reports (ETD)

Unlike the majority of scholarship on the anti-lynching movement, this study focuses on the contribution and interaction of trans-Atlantic participants in the nineteenth century phase of the movement. According to current historiography, the origin of the anti-lynching movement is generally associated with the protest journalism of Ida B. Wells and her exile from the American South in 1892. This study however, redefines that date of origin as well as the period of time in which Americans and persons in the United Kingdom began working together to expose the crime of lynching beyond American shores. In this perspective, the activities of …

Measurement Of Attitude Toward Educational Use Of The Internet In An English Composition Course With A Comparison Of Traditional -Aged And Non-Traditional-Aged Students, Diana Gail Duran May 2003

Measurement Of Attitude Toward Educational Use Of The Internet In An English Composition Course With A Comparison Of Traditional -Aged And Non-Traditional-Aged Students, Diana Gail Duran

Graduate Theses, Dissertations, and Problem Reports (ETD)

Attitude is tied to behavior, and writing behaviors seem to be affected by using a computer. Technological advances have forever changed the way educators view the process of writing, including the way students learn, how they feel about the way they are learning, and their subsequent behaviors. Numerous studies have indicated that using computers to write changes the way students write, what they write, and the quantity and quality of that writing. However, studies disagreed about how these changes occur, whether they are positive or negative (or neither), and what psychological dynamics, such as attitude, are involved, to what degree, …


Gender Differences In Test Anxiety, Angela Marie Josephine Fiore May 2003

Gender Differences In Test Anxiety, Angela Marie Josephine Fiore

Graduate Theses, Dissertations, and Problem Reports (ETD)

The research regarding overall general test anxiety and sex difference is contradictory at best. There is no clear answer to the research question concerning general test anxiety and sex difference according to the literature. An experiment using the modified Suinn Test Anxiety Behavior Scale (1971) was conducted to detect differences between the sexes with regard to test anxiety. There was no overall significant difference between the genders; however, when a multivariate regression was conducted to account for variability contributed by age and class, there was a statistically significant difference. This finding can be perceived as an indication that it is …


Afap-110 Is A Csrc Activator, Joseph Myers Baisden May 2003

Afap-110 Is A Csrc Activator, Joseph Myers Baisden

Graduate Theses, Dissertations, and Problem Reports (ETD)

The cSrc oncogene directs the reorganization of the actin cytoskeleton in both normal and transformed cells. Mutation of protein binding domains (SH2 and SH3) from cSrc results in the deregulation of the kinase and the transformation of cells, while deletion of these domains blocks transformation by active forms of Src. This indicates that SH2/SH3 binding partners for cSrc may play a crucial role in the regulation of this kinase as well as the fulfillment of cSrc-directed functions. One SH2/SH3 binding partner for cSrc being investigated for its role in cSrc transformation is the a&barbelow;ctin f&barbelow;ilament-a&barbelow;ssociated p&barbelow;rotein, AFAP-110. AFAP-110 represents a …

Seasonal Movement And Macro-Habitat Use Of Largemouth Bass (Micropterus Salmoides) In An Ohio River Navigation Pool, Jason Gregory Freund

Graduate Theses, Dissertations, and Problem Reports (ETD)

Largemouth bass provide an important recreational fishery in the Ohio River. Our objectives were to determine critical over-wintering and spawning habitats of largemouth bass in the Belleville Pool of the Ohio River. We surgically implanted radio-transmitters in 39 adult largemouth bass and tracked them over a 23-month period. Our results demonstrate the importance of off-channel habitats in the life history of largemouth bass in large river systems. Sedimentation, resulting in a loss of embayment quality and surface area, is an important problem and thus merits increased attention. Restoration and protection efforts to improve largemouth bass fisheries in large river systems …


Recreational Opportunities And Health Status In West Virginia, Yoav Sneh May 2003

Recreational Opportunities And Health Status In West Virginia, Yoav Sneh

Graduate Theses, Dissertations, and Problem Reports (ETD)

Over half of all Americans are considered to be physically inactive and/or obese, leading to significant individual and societal costs. This study investigates the link between recreational supply and health status for West Virginia. Using spatial econometric techniques, this study provides solid evidence that the demand for health care is positively associated with physical inactivity rates, and that physical inactivity rates are inversely related to the supply of recreational opportunities. When promoting the importance of physical activity as preventative health care, policy makers should consider the provision of recreational opportunities as a means to overcome sedentary behaviors.
