Measuring Aniseikonia Using Scattering Filters To Simulate Cataract, Jason Anthony Wilson Jan 2011

Measuring Aniseikonia Using Scattering Filters To Simulate Cataract, Jason Anthony Wilson

All ETDs from UAB

MEASURING ANISEIKONIA USING SCATTERING FILTERS TO SIMULATE CATARACT JASON WILSON DEPARTMENT OF VISION SCIENCE ABSTRACT The relationship between anisometropia and aniseikonia (ANK) is not well understood. Ametropic cataract patients provide a unique opportunity to study this relationship after undergoing emmetropizing lens extraction. Because light scatter may affect ANK measurement in cataract patients, its effect should also be evaluated. The Basic Aniseikonia Test (BAT) was evaluated using afocal size lenses to produce specific changes in retinal height. Several light scattering devices were then evaluated to determine which produced effects most similar to cataract. Contrast sensitivity and visual acuity (VA) losses were …

Enamel Demineralization Around Bonded Orthdontic Appliances Using Resin Coatings, Michael Brett Wood

All ETDs from UAB

Introduction: Orthodontists work to achieve a favorable esthetic and functional result, only to have the outcome tainted by the presence of demineralization upon appliance removal. The presence of WSL's is a disappointment to both orthodontists and patients. Several products have been developed to prevent this unfortunate damage to tooth structure, including "Opalseal" and "Ortho-coat". Opalseal is a 38% filled primer that releases and recharges fluoride. Ortho-coat is a fluoride releasing, light cure, hydrophilic resin that coats both the bracket and tooth surface preventing decalcification. The aim of this study was to investigate the barrier effect of Opalseal and Ortho-coat compared …

Regulation Of Neuronal Death By The Autophagy Lysosomal Pathway: Implications For Parkinson Disease, Violetta N. Pivtoraiko Jan 2011

Regulation Of Neuronal Death By The Autophagy Lysosomal Pathway: Implications For Parkinson Disease, Violetta N. Pivtoraiko

All ETDs from UAB

Parkinson Disease (PD) is the second most common age-related neurodegenerative disorder and is characterized pathologically by the loss of dopaminergic (DA) neurons in the stubstantia nigra pars compacta (SNpc). Mitochondrial dysfunction, increased oxidative stress, and accumulation of aggregated α-synuclein (α-syn), an intracellular protein involved in synaptic function, are all pathological hallmarks of PD have been implicated in PD pathogenesis. However, it is debated whether α-syn aggregates themselves are responsible for neurodegeneration in PD, cellular pathways involved in degradation of α-syn aggregates are believed to promote neuron survival. The autophagy lysosomal pathway (ALP), a physiological mechanism for recycling of intracellular components, …

Examination Of Ideal Physical Parameter Choices For Efficacious Hyperthermic Treatment Of Cancer, Lauren Rast Jan 2011

Examination Of Ideal Physical Parameter Choices For Efficacious Hyperthermic Treatment Of Cancer, Lauren Rast

All ETDs from UAB

This dissertation presents results on the computational modeling of electromagnetic and thermal effects during the hyperthermic treatment of cancer using magnetic nanoparticles. Magnetic nanoparticle hyperthermia can be used for direct targeting and destruction of tumors through heat treatment or as a complement to chemotherapy. This method of treatment would be much less invasive than many current treatment options. Additionally, since these are nanoscale devices, the hyperthermic treatment of the cancer cells would be extremely localized. This would cause very minimal damage to surrounding tissue, making these systems superior to traditional hyperthermic treatment. The use of ferrofluids for cancer treatment requires …

Myosin Ii In Hippocampal Synapses: Regulation Of Synaptic Plasticity, Strength And Actin Dynamics By Two Distinct Isoforms, Maria Dolores Rubio Jan 2011

Myosin Ii In Hippocampal Synapses: Regulation Of Synaptic Plasticity, Strength And Actin Dynamics By Two Distinct Isoforms, Maria Dolores Rubio

All ETDs from UAB

Cytoskeletal actin filaments underlie dendritic spine plasticity, critical for several forms of learning and memory. Therefore, understanding the mechanisms that regulate actin dynamics is essential to elucidate memory formation pathways. Myosins, a superfamily of actin binding proteins, have emerged as candidates for regulation of actin dynamics in the brain. Several myosin class II isoforms have been identified in brain, but their individual contribution to synaptic activity is still unknown. Based on the finding that myosin IIB regulates actin polymerization in the growth cone of developing neurons and that it is necessary for maintenance of dendritic spine structure, I hypothesized that …

Human Cytosolic Sulfotransferase 2b1b: Structure, Function And Expression In Human Brain, Emily D. Salman

All ETDs from UAB

The human cytosolic sulfotransferases are a family of phase II drug-metabolizing enzymes that conjugate a sulfonate moiety from 3'-phosphoadenosine 5'-phosphosulfate (PAPS) to a hydroxyl moeity on a substrate. SULT2B1b catalyzes the sulfation of hydroxysteroids as well as many xenobiotics; and is expressed extra-hepatically. SULT2B1b is a unique SULT because it has amino (N)- and carboxy (C)-terminal peptide extensions, undergoes post-translational modification, and is localized in both the cytosol and nucleus. Analysis of SULT2B1b revealed that the N- and C-terminal extensions of SULT2B1b are predicted to be intrinsically unstructured peptides. Size exclusion chromatography has revealed that SULT2B1b is enzymatically active as …

Optimization And Characterization Of Bioactive Glass Nanofibers And Nanocomposites, Reginna Evette Scarber

All ETDs from UAB

Disease affects different areas of the bone and can impact individuals of all pathologies and ethnicities. These bone diseases can result in weakening which leads to trauma during ordinary function, the need for reconstructive surgery, and eventual bone replacement. Tissue engineering can provide a less traumatic and more fundamental solution to the current therapies. Bioactive glasses are promising materials in tissue engineering applications because of their ability to form hydroxycarbonate apatite in the presence of simulated body fluid, support cell adhesion, growth, and differentiation, induce bone formation, and concentrate bone morphogenic proteins in vivo. The research in this dissertation will …

Effect Of Different Percentages Of Silica Nanofibers Filler Loads On Mechanical And Physical Properties Of Flowable Composite Resins, Shashikant Singhal

All ETDs from UAB

Dental composites are important in the spectra of restorative materials. Ability to match the color of natural dentition is an appealing characteristic of composite restorations. Additionally, they can be bonded physically to the tooth, which limits the amount of tooth preparation required and thereby conserves healthy tooth structure. In relation to other restorations like amalgams, non-metallic compositions of dental composites have exhibited good biocompatibility. The dental composites are composed of a resin matrix containing a blend of bis-GMA (bis-phenol A-glycidyldimethacrylate) or urethane dimethacrylate (UDMA) along with TEGDMA (tetraethylglycidylmethacrylate). Novel techniques for the reinforcement of these resin-based composites continue in a …

Calciotropic Hormonal Influence On Energy Homeostasis, Lynae J. Hanks Jan 2011

Calciotropic Hormonal Influence On Energy Homeostasis, Lynae J. Hanks

All ETDs from UAB

Energy balance exists when intake is equivalent to expenditure. It has become evident that beyond quantitative aspects of intake, dietary components also have directive impact. On the expenditure side, an underappreciated yet key contributor is resting energy expenditure (REE). As the largest constituent of overall energy output, REE encompasses physiologic, dietary and genetic influence on body composition. While cellular and overall systemic contribution cannot be ignored, the relative proportion of adipose, bone and lean body tissue (i.e., body composition) represents the primary determinant underlying REE. It is possible that the mineral calcium is a common denominator encompassing energy balance influenced …

All ETDs from UAB

Translation of the majority of eukaryotic mRNAs is initiated upon recognition of its 5' cap structure by translation initiation factors in so-called cap-dependent translation. Cap-dependent translation is repressed during cell stress and translation initiation by internal ribosome entry sites (IRESs) predominates. IRESs, located in the 5' untranslated region of specific mRNAs, recruit the ribosome independent of the 5' cap and are essential regulatory elements in many RNA viruses and cellular messages. The dysregulation of cellular IRESs has been linked to cancer because they regulate the expression of genes involved in growth, development and stress response. In comparison to cap-dependent translation, …

Measuring Non-Recurring Congestion In Small To Medium Sized Urban Areas, Bharat Reddy Kallem

All ETDs from UAB

Understanding the relative magnitudes of recurrent vs. non-recurrent congestion in an urban area is critical to the selection of proper measures and the appropriate allocation of resources to address congestion problems. Small to medium sized cities such as Birmingham typically lack the extensive traffic sensor networks necessary to monitor and record traffic performance on a regular basis. Thus alternative methods are needed to gain an understanding of the magnitude of recurrent and non-recurrent congestion and implement proper countermeasures to reduce them. The objective of this thesis was to develop methodologies for quantifying non-recurrent congestion in small to medium sized urban …

Biological Characterization Of Transmitted Human Immunodeficiency Virus Type-1, Tara Grant Edmonds Jan 2011

Biological Characterization Of Transmitted Human Immunodeficiency Virus Type-1, Tara Grant Edmonds

All ETDs from UAB

Heterosexual transmission of human immunodeficiency virus type&ndash1 (HIV&ndash1) accounts for the majority of infections worldwide, with women representing the larger percentage of infected individuals. The events leading to the transmission of HIV&ndash1 at mucosal surfaces are not well defined. Based on the observations that transmitted viruses nearly exclusively utilize the CCR5 coreceptor, and that in 80% of heterosexual transmissions a single virus variant establishes infection, there appears to be a selection mechanism that allows only a subset of viruses to be transmitted. This genetic bottleneck suggests that transmitted viruses may possess specific phenotypic and/or genotypic properties that allow for their …

Molecular Mechanisms Regulating Caenorhabditis Elegans Sperm Migration, Johnathan Wesley Edmonds Jan 2011

Molecular Mechanisms Regulating Caenorhabditis Elegans Sperm Migration, Johnathan Wesley Edmonds

All ETDs from UAB

Fertilization is the process by which male and female gametes join to give rise to a new organism. Union of sperm and ova requires that sperm be able to successfully locate and migrate towards oocytes in the female reproductive tract. By analyzing the in vitro migration of sperm from diverse species and mapping the complex architecture of their female reproductive tracts, we can infer that sperm must respond to directional cues to seek out the mature oocyte. However, the internal fertilization schemes of most complex animals complicate the analysis of in vivo sperm migration. The transparent epidermis of the nematode …
