Regulation Of Ho-1 And Its Role In Angiogenesis, Jessy Deshane Jan 2007

Regulation Of Ho-1 And Its Role In Angiogenesis, Jessy Deshane

All ETDs from UAB

Ischemic tissue and organ dysfunction occur in a variety of cardiovascular diseases. The hypoxic environment created during ischemic injury activates cytoprotective genes, of which heme oxygenase-1 (HO-1) is of great interest. This microsomal inducible enzyme is involved in the homeostasis of prooxidant heme, which is released from heme proteins upon injury. HO-1 responds to a variety of oxidative stress associated stimuli. HO-1 expression has been implicated as a protective response in diverse disease states which has been attributed to the beneficial properties of the by products iron, carbon monoxide and biliverdin/bilirubin. Regulation of expression of HO-1 is also significant, as …


O -Glcnac Modification In Muscle Development, Ping Huang Jan 2007

O -Glcnac Modification In Muscle Development, Ping Huang

All ETDs from UAB

O-glycosylation, a type of posttranslational modification, is abundant and dynamic in the cell, yet its function in cell signaling and destiny regulation is far from known. This study examines the effects of O-glycosylation on muscle differentiation and metabolism, and the potential mechanism behind the effects: proteasome blockade. Proteasome action is required for muscle differentiation. We previously have shown that O-GlcNAc modification of the 19S cap of the proteasome can inhibit the proteolytic function of this organelle. By changing O-GlcNAc modification levels and proteasome function independently in C2C12 skeletal myoblasts, we have found that myoblast differentiation is largely dependent on both. …

Transit Operations Under Emergency Conditions, Amar S. Chaukar

All ETDs from UAB

The events of September 11th and the recent terrorist attacks on transit systems around the world have increased interest in protection and emergency preparedness for the transit systems. Emergency preparedness planning for transit systems is necessary to prevent distractions and effectively respond to major man-made or natural disasters. In this thesis a large-scale dynamic simulation/assignment model was developed and used to evaluate the impact of emergency conditions on transit operations in the Birmingham, AL, area. The Birmingham regional model was developed using the Visual Interactive System for Transport Algorithms. After the base model was tested and calibrated, a major traffic …


Ca 2+ /Calmodulin-Dependent Protein Kinase Ii Regulates The Growth Of Human Osteosarcoma Cells In Vivo, Hyeran Choo Jan 2007

Ca 2+ /Calmodulin-Dependent Protein Kinase Ii Regulates The Growth Of Human Osteosarcoma Cells In Vivo, Hyeran Choo

All ETDs from UAB

Osteosarcoma is the most predominant primary bone cancer among pediatric patients. The pathogenesis and mechanism of osteosarcoma, however, as yet remains unclear. This study investigated the hypothesis that Ca2+/calmodulin-dependent protein kinase II (CaMK II), activated by Ca2+ and its intracellular receptor, calmodulin, plays a critical role in the growth of human osteosarcoma cells. The inhibition of CaMK II with its pharmacologic antagonist KN-93 was used to investigate the role of CaMK II in the growth of human osteosarcoma cells because our preliminary data showed that =-CaMK II is expressed in several human osteosarcoma cell lines. To examine the in vivo …

Isolation And Characterization Of Human Periodontal Ligament Stem Cells, Isabel C. Gay

All ETDs from UAB

The periodontal ligament (PDL) is thought to include progenitor cells capable of forming fibroblasts, osteoblasts and cementoblasts. However, characterization of PDL stem cell populations (SC) remains undetermined due in part, to the diversity of cell types that conform to the periodontal apparatus. Objective: To isolate and characterize PDLSC and assess their pluripotent capabilities to differentiate into bone, cartilage and adipose cell types. Methods: PDL was scraped from human teeth, enzymatically digested, and cells stained for STRO- 1 (SC marker) using fluorescent immunohistochemistry. Positive cells were FACS sorted and expanded in culture. Human bone marrow SC (BMSC) served as a positive …

The Influence Of Insulin On Lipolysis In African American And Caucasian Prepubertal, Premenopausal, And Postmenopausal Females, Laura Lee T Goree

All ETDs from UAB

African Americans, compared to Caucasians, may have chronically suppressed free fatty acid (FFA) mobilization due to basal and postprandial hyperinsulinemia. The pur-pose of this study was to determine if lower FFA among African Americans are due to higher insulin concentration and if this ethnic difference in FFA, beta cell function, and insulin suppression of FFA declines with age. Subjects who qualified underwent a fre-quently-sampled intravenous glucose tolerance test (FSIGT) for determination of insulin sensitivity (Si) and the acute insulin response to glucose (AIRg). Body composition and fat distribution were assessed with dual-energy x-ray absorptiometry (DXA) and com-puted tomography (CT), respectively. …


Determinants That Confer Stop Codon Specificity To Tetrahymena Thermophila Erf1, Cara Hope Heath Jan 2007

Determinants That Confer Stop Codon Specificity To Tetrahymena Thermophila Erf1, Cara Hope Heath

All ETDs from UAB

In eukaryotes, translation termination is a process which is initiated by the presence of a stop codon in the A site of the ribosome and mediated by the binding of a release factor (eRF1). In most eukaryotes, any one of three stop codons UGA, UAG, or UAA, is required for the binding of eRF1. However some organisms, such as the ciliates, have diverged from this universal coding. In one type of ciliate species, Tetrahymena thermophila, UAA and UAG are no longer recognized as stop codons and now both encode a glutamine residue. It was previously thought that domain 1 of …

All ETDs from UAB

Sessile benthic marine organisms such as sponges are frequently colonized by a wide diversity of invertebrates. The present study focused on a quantitative analysis of the mesofauna associated with the common subtropical/tropical sponge Amphimedon viridis and explored several criteria for the basis for this mesofauna-sponge relationship. Specimens of Amphimedon viridis were hand-collected individually in bags from both Saint Joseph Bay, Florida Panhandle, and Sugar Loaf Key, Florida Keys between April - November 2006. Quantitative analyses of sponge surfaces and interiors revealed that the most common sponge-associated group was comprised of amphipods, followed by polychaetes and tenaid crustaceans. 35 percent of …


Verbal Agression In Military Communication: Genetics Vs. Environment, Scott Gregory Johnson Jan 2007

Verbal Agression In Military Communication: Genetics Vs. Environment, Scott Gregory Johnson

All ETDs from UAB

A content analysis was done on various studies involving hormonal effects on verbal and physical aggression in animals ranging from “old world monkeys” to humans in order to prove that genetics is responsible for verbal aggressiveness used by military personnel in the contemporary operating environment. The prevailing belief set is that the military is more aggressive than other social and vocational groups. The analysis shows that military members do not differ in neurophysiology from other groups and species. Only studies on animals with human-like limbic systems were used. The analy-sis includes discussions on the evolution of the use of pure …

All ETDs from UAB

Service-Oriented Enterprises are currently focused on offering enhanced user experiences to customers, employees, and enterprise partners who use the enterprise’s software applications. A better user experience is delivered through the presentation of services and business processes to the user in a composite manner, and by facilitating a better user-application interaction for the user. Our experience with the bioinformatics domain helped us to see that although existing models of enterprise portals offer an integrated environment to present applications and enterprise resources, they are not sufficient to address certain complex user-application interactions. In this thesis, we present a design for a Service-Oriented …

Vitamin D Receptor Deficiency And Postnatal Tooth Formation, Xueming Zhang

All ETDs from UAB

The reduction of caries is one of the major objectives of Healthy People 2010 (USDHHS, 2000). For individuals at risk for caries, early identification and interception before the occurrence of the disease are crucial to preventing the cariogenesis. However, host genetic variants that compromise the mineralization of dental enamel and dentin are unclear. The vdr mutation has been reported to be associated with bone loss. Therefore, it is likely that vitamin D resistance may affect dental enamel and dentin formation. The objective of this study was to investigate the effects of VDR deficiency on postnatal tooth formation in a vdr …

Exposures to dust mite and cockroach indoor allergens are important environmental risk factors in allergic sensitization and the development and exacerbation of asthma. To determine the relationship of indoor allergen levels and residence characteristics, dust samples were collected from indoor surfaces in residences in the Birmingham, Alabama area. The dust samples were analyzed for specific dust mite (Der p 1 and Der f 1) and cockroach (Bla g 1) antigens, the results of which were used to represent the level of indoor allergen present in each residence. The presence, and in some cases the degree, of potential allergen-predicting characteristics of …


Coupling Selection Of The Hiv- 1 Trna Primer Used For Reverse Transcription With Viral Translation And Encapsidation, Uros V. Djekic Jan 2007

Coupling Selection Of The Hiv- 1 Trna Primer Used For Reverse Transcription With Viral Translation And Encapsidation, Uros V. Djekic

All ETDs from UAB

HIV-1 belongs to the Retroviridae family. A hallmark of retroviral replication is the process of reverse transcription. Viral reverse transcriptase requires placement of a cellular tRNA primer onto the primer binding site (PBS) in order to initiate conversion of the viral RNA genome into a double stranded DNA copy. Mutation of the HIV-1 PBS forces the virus to utilize the non-cognate primer. Even though extensive studies have been done over the past 15 years, the mechanism of HIV-1 primer selection has yet to be completely elucidated. HIV-1 captures free tRNA during a yet undefined step in viral replication. However, our …
