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 Jan 2008

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 Jan 2008

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 …

Modulation Of Transforming Growth Factor (Tgf)-Ss1 And Its Implications In Breast Cancer Metastasis, Lakisha Dionne Moore Jan 2008

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 …

Relationships Among Anger, Patterns Of Anger Expression And Blood Pressure, Glucose, And Cortisol In Overweight School-Aged Children, Kimberly Nichols Jan 2008

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 …

Transition Metal Complexes Of Bis(Phosphorus) Donor Ligands Derived From Multifunctional Diols: Synthesis, Isomerization, Cation Binding, And Catalysis., Samuel Britt Owens

All ETDs from UAB

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 …

Investigation Of Lipoteichoic Acid Structure And Function To Establish Its Role In Gram-Positive Bacterial Infections, Ho Seong Seo Jan 2008

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 Jan 2008

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 …

Analysis Of The Hedgehog Pathway In Pancreatic Adenocarcinoma, Adam Steg Jan 2008

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 …

Regulation Of Tau Functions By Posttranslational Modifications Of Tau And Histone Deacetylase 6, Huiping Ding Jan 2008

Regulation Of Tau Functions By Posttranslational Modifications Of Tau And Histone Deacetylase 6, Huiping Ding

All ETDs from UAB

Alzheimer’s disease (AD), the most common neurodegenerative disease, is pathologically characterized by senile plaques composed of amyloid β peptide and neurofibrillary tangles composed of hyperphosphorylated and aberrantly cleaved microtubule-associated protein tau. Numerous studies have demonstrated the critical importance of tau in AD pathogenesis; however, the mechanisms involved in the regulation of tau functions by posttranslational modifications of tau and by other cellular factors need to be further elucidated. The first part of my study focused on how posttranslational modifications of tau, specifically, site-specific phosphorylation and C-terminal cleavage, regulate its physiological function in associating with cytoskeleton, binding to and stabilizing microtubules …

High Field Functional Magnetic Resonance Imaging In The Awake, Behaving Primate: Cortical Networks Involved In Vergence Eye Movements, Matthew K. Ward Jan 2008

High Field Functional Magnetic Resonance Imaging In The Awake, Behaving Primate: Cortical Networks Involved In Vergence Eye Movements, Matthew K. Ward

All ETDs from UAB

Animals with eyes positioned towards the front of the head are capable of making saccadic and smooth pursuit eye movements to fixate an object at a given distance. These eye movements are conjugate (i.e. both eyes move the same amount in the same direction). To fixate objects at different distances, such animals are also capable of making vergence eye movements in which both eyes move the same amount in opposite directions i.e. disconjugately. While purely conjugate or vergence eye movements rarely occur in daily life, it is useful to study these types of eye movements separately due to the relative …
