Rapid Prototyping For Virtual Environments, Emre Baydogan

Electrical & Computer Engineering Theses & Dissertations

Development of Virtual Environment (VE) applications is challenging where application developers are required to have expertise in the target VE technologies along with the problem domain expertise. New VE technologies impose a significant learning curve to even the most experienced VE developer. The proposed solution relies on synthesis to automate the migration of a VE application to a new unfamiliar VE platform/technology. To solve the problem, the Common Scene Definition Framework (CSDF) is developed, that serves as a superset/model representation of the target virtual world. Input modules are developed to populate the framework with the capabilities of the virtual world …

Gene Therapy Using Tet-Repressor System To Modulate Prostate Tumor Microenvironment, Nazita Yousefieh

Theses and Dissertations in Biomedical Sciences

Prostate cancer is the most commonly diagnosed malignancy in men in the United States and is projected to be the third most frequent cause of male cancer-related deaths in 2007 after lung and skin cancers. The initial treatment for prostate cancer at early stages is prostatectomy or radiation, which usually is curative. However, approximately 20% of patients are not cured by such treatments and their cancer recurs, sometimes with long latencies. In other patients prostate cancer is diagnosed only after the cancer has metastasized and there are no effective therapies at this stage. Therefore immunotherapy seems to be a promising …

Un Nouveau Test D’Aide Au Diagnostic Et À L’Évaluation De L’Asthme Professionnel : L’Expectoration Induite, Catherine Lemière, Karim Maghni

Rapports de recherche scientifique

L’asthme professionnel est un asthme causé par l’exposition à des agents professionnels présents sur le lieu de travail. L’asthme professionnel représente environ 10% des cas d’asthme. Le seul traitement efficace de l’asthme professionnel est le retrait de l’exposition à l’agent en cause. Cependant, malgré le retrait de l’exposition, l’asthme persiste chez la grande majorité des patients. Il est donc important de déterminer l’évolution de cette maladie et d’essayer d’identifier des facteurs pouvant prédire son évolution.

Une des caractéristiques principales de l’asthme et de l’asthme professionnel est la présence d’inflammation au niveau des bronches. Un des types cellulaires principaux que l’on …

Catalytic Wet Air Oxidation Of Mono Azo Dye Orange Ii: Catalyst Selection, Reaction Kinetics, And Modeling, Pinar Ozdural

Civil & Environmental Engineering Theses & Dissertations

Wastewaters generated as byproducts of dyeing processes are not treatable with conventional methods. It has been estimated that among the 900,000 tons of different dyes produced annually in the world, approximately 10–15% are lost in wastewater streams during manufacturing and processing operations. Once in rivers and streams, dyes cause major problems, such as reducing light penetration, or displaying toxic effects on aquatic life. Therefore, it is essential that dyes are removed from wastewaters before being discharged into the environment.

This study focuses on the catalytic wet air oxidation (CWAO) of Orange II, a mono azo dye used in large amounts …

Reduced Acute Inflammatory Responses To Microgel Conformal Coatings, Amanda W. Bridges, Neetu Singh, Kellie L. Burns, Julia E. Babensee, L. Andrew Lyon, Andrés J. García

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Implantation of synthetic materials into the body elicits inflammatory host responses that limit medical device integration and biological performance. This inflammatory cascade involves protein adsorption, leukocyte recruitment and activation, cytokine release, and fibrous encapsulation of the implant. We present a coating strategy based on thin films of poly(N-isopropylacrylamide) hydrogel microparticles (i.e. microgels) cross-linked with poly(ethylene glycol) diacrylate. These particles were grafted onto a clinically relevant polymeric material to generate conformal coatings that significantly reduced in vitro fibrinogen adsorption and primary human monocyte/macrophage adhesion and spreading. These microgel coatings also reduced leukocyte adhesion and expression of pro-inflammatory cytokines (TNF-alpha, IL-1 beta, …

Hiv-1 Tat Protein Alter The Tight Junction Integrity And Function Of Retinal Pigment Epithelium: An In Vitro Study., Ling Bai, Zhenping Zhang, Hui Zhang, Xiumei Li, Qiurong Yu, Haotian Lin, Wenhui Yang

Department of Medicine Faculty Papers

BACKGROUND: How HIV-1 enter into the eyes remains obscure. We postulated that HIV-1 Tat protein can alter the expression of specific tight-junction proteins and disturb the blood retinal barrier, and contributes to HIV trafficking into the eyes. This study is to determine the effects of HIV-1 Tat proteins on the barrier function and tight-junction protein expression of retinal pigment epithelial cell (RPE). METHODS: A human RPE cell line (D407) cultured on microporous filter-supports was used. After treating with HIV-1 Tat protein, transepithelial electrical resistance (TER) of confluent RPE cells was measured by epithelial voltmeter. The permeability of the RPE cells …

Good Nietzsche, Bad Nietzsche: The Role Of Friedrich Nietzsche In Richard Rorty’S Political Thought., Paul A. Snell Jr.

CMC Senior Theses

Richard Rorty found Friedrich Nietzsche’s critique of epistemology (perspectivism) to be a helpful tool in getting us to stop thinking of knowledge as something we find, and instead as something that we create. He also found perspectivism to be a helpful tool in that of the private sphere, of private self-creation. The Nietzsche that provides perspectivism is “The Good Nietzsche”. Rorty, however, conceived of Nietzsche’s ideas as being absolutely useless when it comes to politics, along with his ideas regarding morality, the Will to Power, and the Übermensch. These are the ideas of “The Bad Nietzsche”. Rorty’s actual usage of …

The Ethnomedical Context Of Tuberculosis In A Northern Ecuadorian Province, Yamira Alejandra Araujo

Open Access Theses & Dissertations

ABSTRACT

Background. Tuberculosis (TB) prevention and control remains a major global public health challenge. Ecuador has among the highest estimated population prevalence rates for TB, TB-mortality, and multidrug resistant TB in the Americas (WHO, 2007; PAHO, 2004). However, with the exception of one prior study of a high-risk group of suspected cases and household contacts referred for TB testing (Armijos et al., 2008), very little is known about the disease and treatment knowledge, beliefs, attitudes, and practices of Ecuadorian groups and the various socio-cultural and other factors (e.g., rurality, education, gender, disease experience) that shape these. The improved understanding of …

Analysis Of Number And Mass Concentration Of Coarse And Fine, Nancy Garcia

Open Access Theses & Dissertations

There is currently much concern over particles suspended in the ambient air, their effects on people and the environment throughout the world. The suspended particles can cause adverse health effects, reduce visibility and over the course of time wear buildings. Primary air quality concerns are of particles, their effects and their key characteristics. Particle number concentration (NC) of traffic emissions is an important element of the study, specifically heavy duty diesel engine emissions. Particle number concentration is the number of particles of a specific size in a unit of air; in this study they are measured by the number of …

Effect Of Redox-Cycling Agents On Nitric Oxide Synthase Activity In Vitro And Modulation Of Protein Expression In Vivo: No Nitric Oxide Synthase In Mitochondria, Priya Venkatakrishnan

Open Access Theses & Dissertations

This Dissertation describes studies conducted in three areas dealing with the interaction of redox-active compounds with the flavin- and heme- containing enzyme, neuronal nitric oxide synthase (NOS). They are as follows:

I. Studies were initiated using extracts from several varieties of tobacco to identify constituent(s) that could interact with nNOS. Results from [¹⁴C]-L-arginine to [¹⁴C]-L-citrulline conversion assays to which tobacco extracts were individually added, indicate that there are nNOS inhibitors present in tobacco and they are non-polar, lipophilic and non-volatile in nature. In addition, results from assays in which the tobacco-derived redox-active compound, 2,3,6- …
