Effects Of Hexosamine Biosynthesis On An In Vitro Model Of Cardiacischemia, Voraratt Champattanachai
All ETDs from UAB
Increased levels of protein O-linked-N-acetylglucosamine (O-GlcNAc) have been correlated with increased cell survival following stress. Therefore the goal of this study was to determine whether enhanced flux through the hexosamine biosynthesis pathway (HBP), which leads to elevated levels of O-GlcNAc, improved the tolerance of isolated neonatal rat ventricular myocytes (NRVMs) to ischemia/reperfusion (I/R) injury. NRVMs were exposed to hypoxic medium for 4 hours, followed by oxygenated complete medium for 16 hours. Acute treatment with 5 mM glucosamine showed an increase in viability and decreased both necrosis and apoptosis following I/R. Glucosamine increased O-GlcNAc levels maximally at 2 hours and went …

Microbial Biofilm Attachment To Caenorhabditis Elegans, Kevin Drace
Microbial Biofilm Attachment To Caenorhabditis Elegans, Kevin Drace
All ETDs from UAB
The closely related bacterial species Xenorhabdus nematophila, Yersinia pestis and Y. pseudotuberculosis make biofilms capable of adhering to the head of the model nematode Caenorhabditis elegans. Y. pestis uses biofilms to block the digestive tract of its vector, the flea, in order to enhance its efficiency of transmission. I investigated the role of biofilms in X. nematophila and found that, like its Yersinia sp. counterparts, production of biofilm requires a four-gene operon: hmsHFRS. X. nematophila is an insect pathogen and an obligate symbiont of the nematode Steinernema carpocapsae. However, an X. nematophila hmsH mutant that failed to make biofilms on …

Phenomenological Study: What Are Pre-Kindergarten Teachers' Lived Experiences With Children Identified With Conduct Disorder, Oppositional Defiance Disorder, And Attention-Deficit Hyperactivity Disorder In The Southeastern United States?, Danna Benefield Jones
All ETDs from UAB
To date, a vast amount of research has been conducted on disruptive behavior dis-orders such as conduct disorder (CD), oppositional defiance disorder (ODD), and atten-tion deficit hyperactivity disorder (ADHD. However, a paucity of research exists in spe-cific areas such as how teachers’ handle students diagnosed with these disorders. The cur-rent situation in pre-kindergarten may undermine the ability of these students to succeed in the school system. This is seen in the fact that a large number of these students are removed from pre-kindergarten programs across the United States (Webster-Stratton, Reid, & Hammond, 2004). Understanding pre-kindergarten teachers’ lived experiences in handling …

Role Of The Gm/Gn Glycoprotein Complex In The Final Assembly And Egress Of The Human Cytomegalovirus (Hcmv), Magdalena Anna Krzyzaniak
All ETDs from UAB
HCMV consists of a dsDNA genome enclosed by, an icosahedral capsid surrounded by a layer of tegument proteins; the virion structure is enclosed in a lipid envelope rich in virus expressed glycoproteins. The HCMV envelope contains an incompletely defined number of glycoproteins. The glycoprotein M (gM) and glycoprotein N (gN) form a gM/gN protein complex which is the most abundant protein component of the HCMV envelope. Recent studies have indicated that deletion of the viral gene encoding either gM or gN is lethal for HCMV. The gM C-terminal cytoplasmic tail (gM-CT) revealed an acidic cluster and a tyrosine-based trafficking motifs. …

Punctal Occlusion Impact On Tear Film Immuno-Regulatory Proteins Measured By Cytometric Bead-Based Assay, Martin W. Lafrance
Punctal Occlusion Impact On Tear Film Immuno-Regulatory Proteins Measured By Cytometric Bead-Based Assay, Martin W. Lafrance
All ETDs from UAB
PURPOSE: This study compares vendor reagents used for cytometric bead-based assay (CBA) of cytokines in human tears and validates a protocol for use in evaluating punctal occlusion, a treatment for keratoconjunctivitis sicca. It has been proposed that punctal occlusion may alter tear cytokine concentrations based on the facts that: (1) tear clearance, a measure of the balance between tear production and elimination, declines following occlusion and (2) reduced tear clearance and increased levels of pro-inflammatory tear cytokines are correlated in dry eye patients. This study compares tear clearance values and the level of 24 tear cytokines measured by CBA following …

Transcriptional Regulation Of Cd40 And Class Ii Mhc Molecules In Macrophages And Microglia By Statins, Sun Jung Lee
All ETDs from UAB
Microglia/macrophages are the main intrinsic immune effector cells and the first cell types that respond to a variety of CNS injures. They have important functions including secretion of cytokines/chemokines and antigen presentation, thereby regulating immune responses. Interferon-γ (IFN-γ) is a cytokine involved in many aspects of the immune response, and activates microglia/macrophages to express cell surface antigens such as class II MHC, and co-stimulatory molecules such as CD40. CD40 and class II MHC molecules play a critical role in immune reactivity such as antigen presentation and subsequent T cell activation. However, aberrant CD40 and class II MHC expression have been …

The Induction Of First Year And Transferring Elementary School Teachers: A Multiple Case Study, Patricia L. Lequier
All ETDs from UAB
This qualitative, multiple case study explored the experiences of elementary teachers and principals participating in school induction processes. The staggering rates at which new teachers are leaving the profession, coupled with high rates of teacher attrition, teacher retirements, and increases in student enrollment formed the impetus for this study. These factors have collectively contributed to the nation’s crucial demand for close to two million teachers. In an effort to increase the retention rate of new teachers, schools across the nation have implemented teacher induction processes. Teacher induction processes focus on providing support for teachers in their transition from their roles …
Interim Monitoring Efficacy, Safety And Futility In Phase Iii Clinical Trials, Qing Li
Interim Monitoring Efficacy, Safety And Futility In Phase Iii Clinical Trials, Qing Li
All ETDs from UAB
Phase III trials often have both efficacy and safety outcomes. Sometimes the safety outcomes are closely associated with the efficacy outcomes. We sought to find a statistical method to treat both efficacy and safety outcomes as bivariate primary outcomes and set up stopping rules at interim stages based on the following criteria: (1) greater safety; (2) greater efficacy; (3) futility. We first examined the internal pilot design to adjust sample size for clinical trials with a bivariate response (efficacy and safety). Three nuisance parameters (two variances and correlation) need to be considered when doing sample size recalculation for the internal …
The Au-Rich Element Mrna Decay-Promoting Activity Of Brf1 Is Regulated By Mitogen-Activated Protein Kinase Activated Protein Kinase 2, Sushmit Maitra
The Au-Rich Element Mrna Decay-Promoting Activity Of Brf1 Is Regulated By Mitogen-Activated Protein Kinase Activated Protein Kinase 2, Sushmit Maitra
All ETDs from UAB
Regulated mRNA decay is a highly important process for the tight control of gene expression. Inherently unstable mRNAs contain AU-rich elements (AREs) in the 3’ untranslated regions that direct rapid mRNA decay by interaction with decay-promoting ARE-binding proteins (ARE-BPs). The decay of ARE-containing mRNAs is regulated by signaling pathways, which are believed to directly target ARE-BPs. Here, we show that BRF1 involved in ARE-mediated mRNA decay (AMD) is phosphorylated by MAPK-activated protein kinase 2, MK2. In vitro kinase assays using different BRF1 fragments suggest that MK2 phosphorylates BRF1 at four distinct sites, S54, S92, S203, and an unidentified site at …

Modulation Of Transforming Growth Factor (Tgf)-Ss1 And Its Implications In Breast Cancer Metastasis, Lakisha Dionne Moore
All ETDs from UAB
Overexpresssion of transforming growth factor (TGF)-β has been implicated in promoting immune suppression, tumor angiogenesis, tumor cell migration, and invasion in many cancers including carcinoma of the breast. Thus, targeted downregulation of TGF-β1 expression in breast cancer in situ and determination of its implications potentially could provide new treatment approaches for disease management. siRNA constructs targeting TGF-β1 were validated and used to develop clonal derivatives of the MDA-MB-435 metastatic breast cancer cell line. Inhibition of TGF-β1 expression in MDA-MB-435 cells showed decrease in migration and invasion in vitro with an increase in proliferation. In vivo analysis indicated a 90% decrease …
The Role Of Centaurin Alpha-1 In The Regulation Of Neuron Al Differentiation, Carlene Drucilla Moore
The Role Of Centaurin Alpha-1 In The Regulation Of Neuron Al Differentiation, Carlene Drucilla Moore
All ETDs from UAB
In the nervous system, PI 3-kinase has been implicated in neuronal differentiation. My studies have focused on a candidate neuronal PI 3-kinase target centaurin alpha-1, which binds PtdIns(3,4,5)P3, and is an Arf6 GAP. Centaurin alpha-1 is localized in dendrites, dendritic spines and synapses, and is required for neuronal differentiation and spine morphogenesis. In dissociated neuronal cultures, expression of centaurin alpha-1 enhances dendritic branching, and increases dendritic filopodia, lamellipodia and spine-like protrusions. Expression of centaurin alpha-1 GAP inactive mutant or knocking down centaurin alpha-1 levels using siRNA leads to inhibition of dendritic outgrowth and branching. Manipulations of centaurin alpha-1 also disrupt …

Relationships Among Anger, Patterns Of Anger Expression And Blood Pressure, Glucose, And Cortisol In Overweight School-Aged Children, Kimberly Nichols
All ETDs from UAB
Overweight and obesity in school-aged children have become a major health issue. With overweight and obesity, children have increased risk of developing elevated blood pressure readings, glucose levels, and cortisol. Trait anger and patterns of anger expression have been shown to contribute to the elevations of blood pressure, glucose and cortisol in normoweight children and overweight adolescents. However, little research has been done with overweight school-aged children. The purpose of this study was to examine the relationships among trait anger and each of the patterns of anger expression (anger-suppression, anger-out, and anger-reflection/control) and blood pressure, glucose, and cortisol in overweight …

In Chapter 1, the metallacrown ethers cis-[PdCl2{Ph2P(CH2CH2O)3CH2CH2PPh2-P,P’}] and trans-PtCl2{Ph2P(CH2CH2O)3CH2CH2PPh2-P,P’} were studied. These metallacrown ethers are ideal candidates for the study of the kinetics and thermodynamics of cis-trans isomerizations because of their highly flexible backbones. We have carried out these studies using 31P NMR spectroscopy, and the equilibrium constants and thermodynamic and kinetic parameters for these reactions are reported. Chapter 2 of this dissertation explores the cation binding ability of the tartaric acid backbone proposed as the building block for the ligands developed herein for the hydroformylation of styrene. Binding studies and crystallographic analysis confirmed that incorporating the tartaric acid backbone …
Children's Prenumerical Quantification Of Time, Kelly A. Russell
Children's Prenumerical Quantification Of Time, Kelly A. Russell
All ETDs from UAB
Time cannot be seen or physically examined, and philosophers have been arguing about the nature of time for thousands of years. National standards and state courses of study require that very young children be able to measure elapsed time to the hour and minute, but are they truly able to do so? This study focuses on children’s ability to quantify time at the very lowest level of quantification. Second, fourth, sixth, and eighth graders are interviewed using two tasks to determine whether they are able to separate their own actions from the actions of the timing device and to judge …

All ETDs from UAB
Legacy software affects critical functions of our daily lives (e.g., general commercial transactions, scientific applications and military defense systems), and represents a significant investment by government, scientific and corporate institutions. As a consequence of the longevity of such systems, existing legacy software is subject to decay over a period of time, making it increasingly difficult to address changing stakeholder requirements. Modern research approaches for software engineering and programming language design, such as aspect-oriented software development (AOSD), have been investigated as effective techniques for improving modularization of software. However, a general trend in research for supporting aspects has focused primarily on …
Investigation Of Lipoteichoic Acid Structure And Function To Establish Its Role In Gram-Positive Bacterial Infections, Ho Seong Seo
Investigation Of Lipoteichoic Acid Structure And Function To Establish Its Role In Gram-Positive Bacterial Infections, Ho Seong Seo
All ETDs from UAB
Lipoteichoic acid (LTA) is an essential bacterial membrane polysaccharide (cell wall component) that is linked to a glycerol backbone with two acyl chains. Since an antibody to LTA has been shown to protect from Gr+ bacterial infections or colonization, and the mutant Gr+ bacteria which produce less amount of LTA have less pathogenic than WT, LTA may be an important role in Gr+ bacterial infection and inflammation. The currently accepted structure of pneumococcal LTA has the pentameric repeating unit bound to the lipid anchor {Glc(β1��3)AATGal(β1��3)Glc(α1��3)-acyl2Gro}. Unlike the lipid anchor of other Gr+ bacterial LTA, this pneumococcal LTA lipid anchor has …

An Exploration Of Factors Related To Hypertension Control In African American And Caucasian Municipal Employees, Sunun Sinsuesatkul
All ETDs from UAB
Hypertension is a major contributor to morbidity, mortality, and medical costs in the United States. African Americans (AAs) have the highest prevalence of hypertension in the world, exhibiting at least twice the rate for Caucasians in almost every age and sex group. AAs are also at higher risk for complications from hypertension than Caucasians. While several factors have been proposed as accounting for those differences, there is no consensus on which factors may be responsible; the reasons for disparities in hypertension control in AAs are complex, and need further investigation. This study explored relationships between multiple factors to identify how …

Changes In Short-Term Facilitation Are Opposite At Schaffer Collateral And Temporoammonic Ca1 Synapses In The Developing Rat Hippocampus, Haley E. Speed
Changes In Short-Term Facilitation Are Opposite At Schaffer Collateral And Temporoammonic Ca1 Synapses In The Developing Rat Hippocampus, Haley E. Speed
All ETDs from UAB
Hippocampal CA1 pyramidal neurons integrate and filter spatial, temporal, and sensory information from the entorhinal cortex (EC) for memory storage. Synaptic transmission mediates the processing of incoming information, and recent studies have demonstrated that long-term changes in synaptic strength at CA1 synapses are important for learning and memory. Short-term changes in synaptic strength, occurring on a timescale of milliseconds to minutes, do not require lasting modifications and are rapidly reversible. Termed short-term plasticity, it is known to be important for dynamic gain control of synaptic transmission and neural computation. During late postnatal development, there are extensive developmental changes in rat …

Analysis Of The Hedgehog Pathway In Pancreatic Adenocarcinoma, Adam Steg
All ETDs from UAB
Pancreatic adenocarcinoma (PAC) is the fourth leading cause of cancer mortality in the United States. Despite the use of highly aggressive treatment regimens (surgery, chemotherapy and radiation), almost all patients succumb to metastatic disease within 6-10 months of diagnosis. The hedgehog (HH) signaling pathway was originally discov-ered to play a critical role in mammalian embryological development. Interestingly, re-cent studies have suggested that aberrant expression of this pathway is involved in the initiation and continued growth of PAC. Small molecules that antagonize the transmem-brane protein Smoothened (Smo), a critical signaling component of the HH pathway, have proven effective in decreasing PAC …
