Nerve Growth Factor Improves Muscle Healing Following Mechanical Injury, Raouf Bedir, Dalia Saleh, Mona Elshahat, Adel El-Hawary

Mansoura Medical Journal

Muscle injuries are very common in sports and trauma. The need for a quick and more complete recovery of the muscle after injury directs the at­tention towards growth factors, which are hormone-like biologically active polypeptides that control cell growth and differentiation. It was observed that nerve growth factor (NGF) is a potent stimulator of myoblast prolife­ration and fusion in vitro, thus, it was anticipated that NGF could enhance muscle healing in vivo. Six adult albi­no rats were used in this study. Both right and left gastrocnemius muscles of the albino rats were cut at 60% of their length from their …

Law And Public Health: Beyond Emergency Preparedness, Wendy K. Mariner

Faculty Scholarship

This Article examines three questions: What is public health? What is public health law? What roles can lawyers play in public health? It first describes the breadth of public health, highlighting six trends shaping its future: social determinants of health; synergy between medicine and public health; shifts in focus from external (e.g., environmental and social) to internal (behavioral) risks to health; federalization of public health law; globalization of health risks and responses; and bioterrorism. Because the domains of law that apply to public health are equally broad, the Article next offers a conceptual framework for identifying the types of laws …

Child Psychological Abuse Sexual Attitudes And Sexual Satisfaction: An Examination Of Disclosure Gender And Perpetrator Relationship Differences, Natasha Coy

Psychology Theses & Dissertations

The current project examined the associations between childhood psychological abuse, disclosure, and perpetrator relationship on sexual attitudes and satisfaction among adults. A total of 274 female graduate and undergraduate psychology students from Old Dominion University were recruited. Participants anonymously filled out the survey online. It was hypothesized that there would be a positive relationship between childhood psychological abuse and sexual communion and permissiveness. In terms of perpetrator relationship, it was hypothesized that as the objective relationship between the individual and perpetrator became closer, sexual attitudes and satisfaction would be more negatively affected. It was also hypothesized that one's subjective relationship …

An Examination Into The Effects Of Social Positioning And Capitalist Immersion On Gendered Attitudes Towards Homosexuality In The United States, Fiona J. Blee

Sociology & Criminal Justice Theses & Dissertations

Previous research on attitudes towards homosexuality has concentrated on characteristics of individuals, and neglected the capitalist structure of society that provides the contextual setting for the creation and maintenance of cultural attitudes.

This thesis uses responses collected in the general social survey of the United States between 1993 and 1998, to provide a more comprehensive explanation of differences in attitudes towards homosexuality, through an analysis of social position and the capitalist agenda. The analysis revealed significant relationships between sex, age, race, income, beliefs regarding the domestication of women, and attitudes towards homosexuality.

The analysis showed that respondents categorized as black …

The Defensin Gene In Dermacentor Variabilis And Ixodes Scapularis, Katherine Corbett Seguin

Biological Sciences Theses & Dissertations

In response to microbial challenge, invertebrates rely on their innate immune response to recognize and destroy harmful pathogens. One of the primary proteins produced by the response and that has been observed in many invertebrates, including insects, mussels, and ticks, is defensin. These proteins are responsible for forming pores in the membranes of invading microbes thereby destroying them. This study examined the gene coding region for defensin in two important tick disease vectors, Dermacentor variabilis and Ixodes scapularis. PCR amplification of the genes from tick chromosomal DNA resulted in the amplification of a 225 base pair amplicon. Sequencing of …

Feeding Behavior And Conditioning In Two Heterotrophic Dinoflagellates, Todd A. Egerton

Biological Sciences Theses & Dissertations

Growth and abundance of heterotrophic dinoflagellate predators are generally attributed to the availability of algal prey. Several species of dinoflagellates feed on a wide variety of food types including fish. However the actual feeding preferences of dinoflagellates have been much less studied. In the few studies that have been carried out on dinoflagellate feeding preference, none have looked at possible factors that may affect preference. I conducted three experiments on the toxic dinoflagellate Pfiesteria piscicida and the related unnamed species Cryptoperidiniopsis brodyi which, (1) calculated the feeding preferences between algal Rhodomonas prey and fish blood cells and identified factors that …

Morphological And Molecular Defects In Zebrafish Embryos (Danio Rerio) After Chromated Copper Arsenate Exposure, Kerry Jean Lee

Biological Sciences Theses & Dissertations

This investigation identified the morphological defects caused by different concentrations of chromium, copper, and arsenic (CCA) on the developing zebrafish embryo; in addition to defects caused by the three combined components (complete CCA). A change in the DNA of the developing embryos in response to the three components of CCA and complete CCA was also determined. Early Dania rerio embryos were cultured for five days with various concentrations of CCA components and complete CCA. Morphological defects were assessed with light microscopy and DNA fragmentation was determined by agarose gel electrophoresis. Embryonic exposure of D. rerio to sub lethal concentrations of …

Correlation And Causes Of Fifth Order Cycles Within The Upper Cretaceous Eagle Formation, Bighorn Basin Of Wyoming, Kimberly Ann Johnson

OES Theses and Dissertations

Cyclic stratification was examined in the Upper Cretaceous (Santonian-Campanian) section (Eagle Formation) within the Bighorn Basin of Wyoming. Of particular concern was the 10³ to 10⁴ year band, which in marine settings has been attributed to orbital forcing (Milankovitch cyclicity). A series of 19 sections were measured through the Virgelle Member of the Eagle Formation. Most were measured on the “J”-shaped escarpment that constitutes the nose and north flank of the Thermopolis anticline. Several others were measured at sites up to 30 km to the northwest along paleo-shoreline. In the study, detailed thickness data of all sections and …

A Systems Methodology For Measuring Operational Organization Effectiveness: A Study Of The Original Equipment Computer Manufacturing Industry, 1948 To 2001, Teddy Steven Cotter

Engineering Management & Systems Engineering Theses & Dissertations

Optimizing operational organizational effectiveness is the central, although often unstated, goal of engineering management and systems engineering research and applications. Two fundamental problems remain to be addressed in pursuit of this goal. First, despite over fifty years of research in various disciplines, there is still no universally accepted definition of organizational effectiveness. Second, no methodology exists to identify the domains, dimensions, and determinants of operational organizational effectiveness and dynamically model operational organizational effectiveness within a given population.

This research synthesizes a systems engineering methodology for identifying the domains, dimensions, and determinants of and dynamically modeling operational organizational effectiveness for an …

Carbon Nanotubes And Tungsten Oxide Nanorods: Synthesis And Applications, Bing Xiao

Electrical & Computer Engineering Theses & Dissertations

Synthesis and applications of two types of one-dimensional nanomaterials, carbon nanotubes (CNTs) and tungsten oxide nanorods, are investigated in this dissertation. Multi-walled CNTs have been successfully synthesized using two types of chemical vapor deposition (CVD) methods: microwave plasma enhanced CVD and atmospheric pressure thermal CVD. CNTs and their synthesis processes are characterized with various analysis techniques including scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy, and optical emission spectroscopy. Ultra-thin and high quality multi-walled CNTs are discovered in CNT films produced by MPCVD, which exhibit good field emission performance that is found to be dependent on the synthesis …

Beta-Alanine Suppresses Heat Inactivation Of Lactate Dehydrogenase, Ankur D. Mehta, Norbert W. Seidler

Student Publications

Beta-Alanine exhibits neurotransmitter activity and is a component of the anti-glycation agent carnosine. We propose that beta-alanine may have additional properties which may be of physiological significance. Interestingly, stress modulates the level of beta-alanine, which regulates excitotoxicity responses and prevents neuronal cell death. We hypothesize that beta-alanine's protective role may involve preservation of enzyme structure and function, suggesting that beta-alanine may act as a chemical chaperone. We used light scattering, enzyme activity and intrinsic fluorescence to monitor heat-induced changes in lactate dehydrogenase (LDH) in the presence and absence of beta-alanine. We observed that beta-alanine suppressed heat-induced LDH inactivation, prevented LDH …

The Role Of Interfunctional Market Orientation In New Product Program Success: An Exploratory Empirical Analysis, George Grady Gresham

Theses and Dissertations in Business Administration

A central tenet of the market orientation construct is the need for virtually all departments, not just the marketing department, to participate in gathering, disseminating and responding to market intelligence. Previous academic research provides empirical support for a positive relationship between market orientation and superior business performance. Superior business performance, for many firms, depends upon a continuous stream of new products emerging from their product development programs, yet few studies have demonstrated the link between market orientation and new product development program success. This dissertation conceptualizes market orientation below the strategic business level as interfunctional market orientation (IFMO) for cross-functional …

Mechanisms Of Cell Death Initiated In Herpes Simplex Virus Thymidine Kinase Expressing Colon Tumor Cells Treated With Ganciclovir And Ucn-01, Christina Elizabeth Ahn

Theses and Dissertations in Biomedical Sciences

Metastatic colon carcinoma is the second leading cause of death from malignancy in the United States, and development of more effective treatments is essential. Heterologous expression of Herpes Simplex Virus Thymidine Kinase (HSVtk) in combination with the prodrug, ganciclovir (GCV), has shown great promise for the genetic therapy of many cancers, but most patients have had only a partial or minimal response to the therapy. After screening a panel of two drug combinations, our laboratory has shown that the combination of GCV and the protein kinase inhibitor UCN-01 (7-hydroxystaurosporine) enhances tumor cell death more effectively than either drug alone. However …

Developing And Optimizing Conditions For Single Cell Genetic Analysis, Susan Adele Gitlin

Theses and Dissertations in Biomedical Sciences

Preimplantation Genetic Diagnosis (PGD) allows for couples to obtain genetic information at the embryo stage, therefore preventing lethal genetic diseases in their offspring. A recent multi-center study determined a 17% amplification failure rate overall and a 3.4% misdiagnosis rate (ESHRE PGD consortium steering committee, 2002). Experiments presented here were conducted to decrease those rates by optimizing single cell sensitivity and specificity of PGD techniques. Primer extension preamplification (PEP) was used after initial amplification failure, followed by gene specific PCR. Reamplification experiments yielded 54% amplification rates using blastomeres that previously failed amplification. In the clinical trial, four of six blastomeres were …

The Antitumor Agent, Arglabin-Dma, Preferentially Induces Apoptosis In Human Colon Tumor Cells, Sung Wook Kwon

Theses and Dissertations in Biomedical Sciences

Arglabin-DMA, an analog of farnesyl pyrophosphate (FPP), reportedly inhibits farnesyltransferase (FTase) directly by competitively blocking the binding of Ras protein and its posttranslational modification, as suggested in previous studies. But, the mechanisms by which Arglabin-DMA inhibits tumor growth in vivo and in vitro are still relatively poorly characterized. To determine the mechanism by which this drug inhibits tumor growth, the effects of Arglabin-DMA in two human colon tumor cell lines (mutant K-ras HCT 116 and wild-type ras HT-29) were explored on cell proliferation, apoptosis, and cell cycle kinetics in vitro. In cell viability studies, we showed that Arglabin-DMA …

Defensin In The Ticks Dermacentor Variabilis And Ixodes Scapularis, Shane Michael Ceraul

Theses and Dissertations in Biomedical Sciences

This dissertation presents the identification, molecular structure and expression of defensin, an antimicrobial peptide, in the ticks, Dermacentor variabilis and Ixodes scapularis. A 624 bp cDNA molecule for defensin was cloned and sequenced from hemocytes, fat body and midgut of unstimulated D. variabilis ticks. Defensin peptide was detected only in the hemocyte lysates. These results suggest that the defensin from D. variabilis is synthesized and stored in the hemocytes, although the role of other tissues is not excluded.

The ability of the juvenile stage ticks to express the defensin gene was confirmed. Detection of the defensin transcript in all …

Cultural Competence And Curricula In Physical Therapist Professional Education, Beth Ernst Jamali

Theses and Dissertations in Urban Services - Urban Education

The purpose of this research was to examine the methods and degree to which content related to cultural competence is incorporated into current entry-level physical therapist education. Face-to-face interviews were performed with 10 program directors from various physical therapist education programs across the country to obtain in-depth information regarding cultural competence in the physical therapy curricula. A questionnaire was sent to all of the 193 accredited physical therapist education programs in the United States as a second means to collect information regarding the methods and extent to which cultural competence is included in the physical therapy curricula. Data were collected …

Statistical Analysis Of Longitudinal And Multivariate Discrete Data, Deepak Mav

Mathematics & Statistics Theses & Dissertations

Correlated multivariate Poisson and binary variables occur naturally in medical, biological and epidemiological longitudinal studies. Modeling and simulating such variables is difficult because the correlations are restricted by the marginal means via Fréchet bounds in a complicated way. In this dissertation we will first discuss partially specified models and methods for estimating the regression and correlation parameters. We derive the asymptotic distributions of these parameter estimates. Using simulations based on extensions of the algorithm due to Sim (1993, Journal of Statistical Computation and Simulation, 47, pp. 1–10), we study the performance of these estimates using infeasibility, coverage probabilities of the …

The Straggling Green's Function Method For Ion Transport, Steven Andrew Walker

Mathematics & Statistics Theses & Dissertations

For many years work has been conducted on developing a concise theory and method for HZE ion transport capable of being validated in the laboratory. Previous attempts have ignored dispersion and energy downshift associated with nuclear fragmentation and energy and range straggling. Here we present a Green's function approach to ion transport that incorporates these missing elements. This work forms the basis for a new version of GRNTRN, a Green's function transport code. Comparisons of GRNTRN predictions and laboratory results for an ⁵⁶Fe ion beam with average energy at the target of one GeV/amu or more are presented for …

The Great Pestilence: Yellow Fever In Portsmouth, Virginia, 1855, Burden Susan Lundgren

Health Services Research Dissertations

In 1855, the town of Portsmouth, Virginia was devastated by an epidemic of yellow fever. Most citizens fled. Of those who remained, most became infected and a thousand died. The municipal government collapsed. In their place, a small organization known as the Portsmouth Relief Association assumed responsibility for ensuring the survival of the town. This organization managed the care of the sick, the burial of the dead, and the care of orphans. It was the sole agent receiving and allocating the funds and resources that poured into the community. Scarce food, drugs and other supplies were available only through the …

2004 Great Bay Organic Nitrogen (Pon & Don) And Light Extinction (Par) Monitoring Program, Jonathan Pennock

PREP Reports & Publications

Nitrogen is most often considered to be the limiting nutrient for plant growth in marine waters. As a result, knowledge of nitrogen loading and ambient water-column concentrations are considered to be critical to understanding the response of aquatic ecosystems to nutrient over-enrichment—a process known as eutrophication when it results in the excess production of organic matter. Plant production in many estuarine systems may also be limited by light availability as a result of high levels of turbidity in the water resulting from sediments, dissolved organic matter, and phytoplankton in the water column. Light limitation resulting from human-induced increases in turbidity …
