Fatigue Testing Of Straight And Angled Abutments In A High Torque Dental Implant System, Rana M. Atieh
Fatigue Testing Of Straight And Angled Abutments In A High Torque Dental Implant System, Rana M. Atieh
All ETDs from UAB
Root form dental implants are a common solution used today to replace missing teeth. However current designs still suffer from a number of limitations. Angled abutments are used for incisors, where maximum human bite forces are normally < 200N, while straight abutments are used for molars subjected to higher forces > 200 N. The aim of this study was to evaluate the mechanical performance of a novel dental implant system by fatigue testing straight and 15-degree angled abutments. It was hypothesized that the novel thread design will dissipate the load evenly throughout the implant allowing the system to withstand normal chewing forces. Implants with 4.2mm diameter were tested according to ISO 14801 in specimen …
Francisella Tularensis Lvs Invasion Of Primary Murine Macrophages And Mtor Signaling, Michael Warren Edwards
Francisella Tularensis Lvs Invasion Of Primary Murine Macrophages And Mtor Signaling, Michael Warren Edwards
All ETDs from UAB
Francisella tularensis is an intracellular pathogen and the etiologic agent of tularemia. Because virulent strains cause morbidity and lethality in human, the attenuated live vaccine strain (LVS) has been used to study F. tularensis pathogenesis in murine models, since the disease in mice resembles human tularemia. Despite growing knowledge about host responses to Francisella infection, there is scarce information on the cell signaling events involved in Francisella host cell entry and in early immune re-sponses. Therefore, the purpose of this dissertation was to assess the involvement of the mammalian target of rapamycin (mTOR) in these processes. First, we evaluated the …

The Role Of Wnt5a In Tumor Suppression And Differentiation, Stephanie Easter
All ETDs from UAB
TGF-beta and the Wnt signaling pathways play key roles in regulating ductal growth and branching morphogenesis in the mammary gland. Disruption to this signaling can cause deregulation of the normal mammary stem cell population and foster an environment favorable for tumorigenesis and recurrence. Recent studies show that TGF-beta up-regulates expression of the non-canonical Wnt, Wnt5a, in the mammary gland and that Wnt5a antagonizes canonical Wnt/beta-catenin signaling in mammary epithelial cells. Canonical Wnt/beta-catenin signaling has been strongly implicated in expanding the mammary stem/progenitor cell pool. Here, we test the hypothesis that Wnt5a suppresses the expansion of the mammary stem and progenitor …

Current paradigms of carcinogenic risk suggest that genetic, hormonal, and environmental factors combine to influence an individual's predilection for breast cancer and related metastatic tumor formation. The genetic component, in particular, has become the focus of many emergent studies. A renewed focus on cancer metabolism and the Warburg effect has similarly cast a spotlight on the role, if any, of the mitochondrion in directing disease progression. Analysis of the direct contribution of mitochondrial DNA on tumorigenicity is made possible through the use of mitochondrial-nuclear exchange (MNX) mice in which nuclei from normal FVB mice (the background strain of the tg: …

An Evolutionary Study Of Dynamic Cognitive Game Captchas: Automated Attacks And Defenses, Song Gao
All ETDs from UAB
CAPTCHAs represent a primary defense mechanism against online attacks and resource abuse. However, existing CAPTCHA solutions (e.g., distorted static text-based CAPTCHAs) suffer from significant security problems. Recent research has demonstrated that many current forms of CAPTCHAs can be solved with a high accuracy using automated techniques. This vulnerability associated with traditional CAPTCHAs thus provides a sound motivation to explore CAPTCHA alternatives. In this dissertation, we study a broad class of game-based CAPTCHAs, called the Dynamic Cognitive Game (DCG) CAPTCHAs, which challenge the user to perform a game-like cognitive task interacting with a series of dynamic objects. Specifically, we focus on …

Parkinson's disease (PD) is the second most common neurodegenerative disorder. Two major factors in both familial and sporadic PD are mitochondrial dysfunction and insufficient autophagy. My thesis research focuses on the interplay between these activities in PD. To investigate the common and differential effects of PD-inducing neurotoxins on mitochondrial bioenergetics and their relationships to cell survival, we used an in vitro culture system, differentiated dopaminergic SH-SY5Y neuroblastoma cells. We found that the neurotoxins rotenone, 1-methyl-4- phenylyridinium (MPP+) and 6-hydroxydopamine (6-OHDA), decreased mitochondrial respiration and induced cell death in these cells. The extent and characteristics of mitochondrial dysfunction in response to …
Regulation Of Skeletal Muscle Plasticity Using Engineered Configurations Of The Transcription Factors Myod And E12, Vladimir Grubisic
Regulation Of Skeletal Muscle Plasticity Using Engineered Configurations Of The Transcription Factors Myod And E12, Vladimir Grubisic
All ETDs from UAB
Skeletal muscle fibers, although terminally differentiated, can change their features, such as contraction speed and endurance, and throughout adult life in response to variety of stimuli, like exercise. This process is called plasticity and is mainly regulated by the type of nerve activity. Over the past several decades, research has shown that the properties of myofibers are also determined during muscle development. Ultimately, the change in phenotype requires a change in gene expression which is, in turn, regulated by transcription factors (TFs). Basic helix-loop-helix (bHLH) TFs regulate myogenesis and the central role belongs to the myogenic differentiation 1 (MyoD), often …

The Role Of Human Ficolin-2 During Invasive Pneumococcal Disease, Allison Marie Brady
All ETDs from UAB
Streptococcus pneumoniae (pneumococcus) is a significant human pathogen that typically resides in the nasopharynx of humans. The major virulence factor of pneumococcus is its capsular polysaccharide, of which it can express over 90 unique serotypes. However, there is great disparity in which serotypes colonize or cause disease, though the reason for these differences are not well understood. Serotype 11A is one such serotype that frequently colonizes the nasopharynx of children, but rarely causes disease. Interestingly, serotype 11E, a variant of 11A, varies only in the O-acetylation of a galactose residue in its polysaccharide repeating unit. This difference in structure is …

Malignant peripheral nerve sheath tumors (MPNSTs) are the most common cause of death in patients with neurofibromatosis type-1. These aggressive, Schwann cell-derived tumors have no treatment beyond surgical resection. Developing targeted chemotherapeutics remains crucial to improving patient survival. The Schwann cell mitogen neuregulin-1 (NRG1) was shown to mediate the migration, proliferation and survival of MPNSTs. Furthermore, overexpression of NRG1 in Schwann cells (P0-GGF beta 3 mice) on an outbred C57BL/6J x SJL/J background induced the formation of neurofibromas and MPNSTs similar to human disease, yet these mice have intact neurofibromin. To determine if NRG1 acts within the same signaling cascade …

Cd5-Dependent Ck2 Activation Is Critical For The Maintenance Of B-1a B Cells, Kevin S. Cashman
All ETDs from UAB
CD5 has classically been shown to act as a negative regulator of antigen receptor signaling, however recent evidence has discerned that the CD5 molecule contains a previously undefined cytoplasmic domain which constitutively binds inactive CK2 and facilitates its activation through CD5 ligation. With the development of a mouse model which contains a micro-deletion knock-in form of CD5 which lacks the amino acids necessary to facilitate this CD5-CK2 interaction, it is now understood that CD5 plays a more significant role in cellular physiology than previously appreciated. T cells from this mouse model show increased AICD and dysregulation in T helper subset …

This qualitative case study explored the factors that contributed to how typical book reading practices and the time spent on book reading were implemented during the school day. Previous research has shown the importance of reading books to young children and that providing access to books has led to reading growth and progress. However, little research has focused on actually identifying how or if books are used during the course of a classroom day. This investigation was conducted in three elementary schools within two school districts in the southeastern United States. Study participants included eight elementary teachers who taught a …

Recognition Of Hiv-1 Cryptic Epitopes During Infection And Following Vaccination, Anne Bet
All ETDs from UAB
Cryptic epitopes (CE) are a unique set of human leukocyte antigen class I (HLA-I)-restricted peptides that are encoded by alternative reading frames (ARFs) of genes. During human immunodeficiency virus-1 (HIV-1) infection, CE translated from either sense or antisense transcripts elicit epitope-specific CD8 T cell responses. Previous studies using simian immunodeficiency virus (SIV)-vaccinated animals have shown that an increased breadth of CD8 T cell responses is correlated with controlling viral replication, therefore stressing the potential clinical benefit of vaccine-induced T cell responses to a diverse set of viral epitopes. Yet, the genetic profiles and immunological significance of CE remain poorly understood. …

Apolipoprotein A-I (ApoA-I), the major lipid-binding protein of high-density lipoprotein (HDL), can suppress inflammation and autoimmunity in hypercholesterolemic mice by modulating cellular cholesterol homeostasis and lipid oxidation. However, the cellular and molecular mechanisms involved are poorly understood, and whether ApoA-I or ApoA-I mimetic peptides can similarly exert immunosuppressive effects or improve inflammatory organ disease in SLE under normolipidemic conditions remains unresolved. We therefore first took a genetic approach in which bone marrow from SLE-prone Sle123 mice was transferred into wild-type, ApoA-I knockout (ApoA-I-/-) and ApoA-I transgenic (ApoA-Itg) mice. Transgenic expression of ApoA-I suppressed CD4+ T and B lymphocyte activation, reduced …

Examining Neuropsychological Sequelae Of Chronic Pain And The Effect Of Immediate-Release Opioid Analgesics, Cady Block
All ETDs from UAB
Introduction: Patients commonly complain of subjective side effects of opioid use, including forgetfulness, slowed processing speed, confusion, and sedation - which have raised concerns about potential cognitive impairment. However, research on the effects of opioids on objective neuropsychological performance is thus far equivocal and, unfortunately, many of the studies cited as support for opioid-related impairment do not fully account for the neuropsychological effects of chronic pain, which has been shown to affect many of the same neuropsychological domains purported to be affected by opioids. To that end, we sought to examine whether: 1) chronic nociceptive pain itself results in objective …

The Role Of The Developing Microbiome In Mucosal Defense Of The Neonatal Gut, Emily G. Blosser
All ETDs from UAB
Neonatal late-onset sepsis is invasive infection occurring after the first 48 hours of life, and one of the leading causes of death among preterm infants in the United States and abroad. Infections with Gram-negative bacteria, such as Klebsiella pneumonia, occurring when bacteria translocate across premature gut epithelium into the bloodstream, can be particularly severe. Preterm infants in the neonatal intensive care unit undergo intense antibiotic regimens due to high risk of infection. Paradoxically, prolonged exposure of preterm infants to empiric antibiotic therapy early in the hospital stay is associated with increased risk of intestinal infection and death after adjustment for …

The main purpose of this pilot study was to investigate the insulin sensitizing effect of glycine as a dietary supplement in insulin resistant (IR) normoglycemic subjects (N= 10), and to determine significant changes in insulin sensitivity and lipid profile after four weeks of glycine supplementation. Descriptive statistics were used to describe the basic characteristics of the study population. A paired t-test was used to determine differences between insulin sensitivity and lipid profile pre- and post- intervention, considering the estimation of HOMA-IR and Matsuda- index scores. Results showed that glycine supplementation might improve triglyceride (TG) levels in European Americans; and low-density …

For many people of the world, fish is a primary source of protein, especially in countries like Ghana, where about 60% of the protein consumed is derived from fish. Fish advisories have been established by some nations to protect the public from harmful health effects linked to eating contaminated fish. Methylmercury (MeHg) is one such contaminant that has resulted in fish advisories. Fish advisories have not been developed in Ghana, although MeHg contamination of aquatic ecosystems is likely due to the long history of mercury (Hg) use in artisanal gold mining. To address this gap in our knowledge, I compiled …

Ovarian cancer while the second most common gynecologic malignancy is the most commons cause of death due to a gynecologic malignancy and the fifth most common cause of death to cancer in women. In 2014, there will be an expected 21,980 cases and 14,270 deaths. Unfortunately, the five-year survival for ovarian cancer is only 40% and this has barely increased over the past 30 years. New approaches need to be developed in order to study ovarian cancer and identify methods of overcoming chemotherapy resistance. This dissertation presents the work conducted in the development of a patient-derived xenograft model of ovarian …
The Role Of The Planar Cell Polarity Pathway In The Second Heart Field During Outflow Tract Morphogenesis, Tanvi Sinha
The Role Of The Planar Cell Polarity Pathway In The Second Heart Field During Outflow Tract Morphogenesis, Tanvi Sinha
All ETDs from UAB
Outflow Tract (OFT) malformations underlie a majority of congenital heart defects (CHD) in humans and are a leading cause of childhood mortality. The OFT, which gives rise to the aorta and pulmonary artery of the heart, relies on the contribution of the Second Heart Field (SHF) progenitors in the pharyngeal and the splanchnic mesoderm, outside of the initial heart. OFT morphogenesis requires highly regulated SHF development involving the proliferation, differentiation and deployment of the SHF progenitors to the heart. Extensive studies elegantly demonstrate how transcriptional networks integrating signaling input from multiple pathways finely balance the proliferation and differentiation of SHF …
Modulation Of The Immune Response To Aspergillus Fumigatus By Antibodies To Conserved Bacterial Polysaccharides, Emily Stefanov
Modulation Of The Immune Response To Aspergillus Fumigatus By Antibodies To Conserved Bacterial Polysaccharides, Emily Stefanov
All ETDs from UAB
The incidence of asthma, allergies and autoimmune diseases has increased dramatically in developed countries. The hygiene hypothesis postulates that excessively sanitary conditions lead to a lack of critical immune stimulation during early life, leading to inappropriate responses to self or harmless antigens later in life. Many bacteria and potential allergens share common polysaccharide epitopes. We investigated the ability of antibodies against these shared polysaccharides to dampen the immune response to the ubiquitous fungus and potent allergen, Aspergillus fumigatus. We found that antibodies against these polysaccharides, specifically of the IgM isotype, induced by neonatal bacterial immunization or passive antibody transfer, dampened …

Constraint-Induced Movement (CI) therapy has been found to produce substantial improvements in upper-extremity functioning in both adults and children following damage to the central nervous system (CNS), including stroke, traumatic brain injury and cerebral palsy. In addition, structural changes in the sensorimotor cortices and bilateral hippocampi have been observed in both adults and children following CI therapy treatment for upper extremity hemiparesis. Although most research has been conducted in patients with such static injuries as strokes and TBI, clinical efficacy of CI therapy has also been demonstrated in a small number of patients with the progressive autoimmune disorder, multiple sclerosis …

Characterization Of Phosphatidylinositol 4,5-Bisphosphate Regulation Of The Electrogenic Na/Bicarbonate Cotransporter Nbce1, Ian Michael Thornell
All ETDs from UAB
The electrogenic Na/bicarbonate cotransporter (NBCe1) is an acid/base regulator that is also involved in coordinating epithelial ion transport. Splice variants of NBCe1 differ at their cytosolic amino- (N-) and/or carboxy- (C-) termini. These different cytosolic termini impart differential regulation for each variant. For example, the N-terminus of NBCe1-A is autostimulatory, whereas the N-terminus of NBCe1-B and -C is autoinhibitory. We examine the regulatory role of PIP2 for NBCe1 splice variants. In the first study of this dissertation, we characterize the effect of increasing PIP2 on the activity of NBCe1-A, -B, and -C expressed in Xenopus laevis oocytes. Injecting PIP2 stimulated …

ABSTRACT Background Interleukin 8 (IL-8) and Interferon gamma inducible protein 10 (IP-10) are pro-inflammatory chemokines that may play key antagonistic roles in regulating corneal immune privilege and angiogenesis prevention. Some groups have reported that tear levels of IL-8 and IP-10 measured by multiplexed antibody-based assay are artifact prone and therefore unreliable, leading to their under-utilization as ocular surface disease and dry eye biomarkers. The current study compares tear levels of IL-8 and IP-10 measured by multiplexed cytometric bead-based assay (CBA) with single analyte ELISA assay. Mass spectrometry, a non-antibody based method, was also used to obtain confirmation of tear levels. …

The sorting and degradation of endocytosed cargo by the endosome regulates many cellular functions common to all cells. Neural cells appear to be particularly vulnerable to perturbation in endo-lysosomal transport, and several neurological disorders are caused by a primary deficit in this pathway. In this dissertation, I show that the spontaneously occurring neurological mutation teetering (tn) is a single nucleotide substitution in the endosomal cargo-sorting component hepatocyte growth factor-regulated tyrosine kinase substrate (Hgs/Hrs) that reduces the abundance of HRS. By 3 weeks of age, the tn mice exhibit heightened pain sensitivity, muscle weakness and reduced muscle size. The loss of …

Using Neuroimaging To Predict Treatment Response In Patients With Schizophrenia, Nathan Lyle Hutcheson
All ETDs from UAB
Schizophrenia is a severe debilitating mental illness that affects approximately 1% of people worldwide. Compared to healthy controls (HC), patients with schizophrenia (SZ) have memory deficits, specifically prominent disruptions in their episodic memory. These memory disruptions are thought to be caused by altered structure and function of areas within the memory network, specifically the prefrontal and temporal lobe including the hippocampus. Recently, identifying biomarkers of treatment response by using neuroimaging has become a prominent area of interest in schizophrenia. Biomarkers in schizophrenia could help by allowing for more efficient treatment using current method and also the development of novel treatments. …

All ETDs from UAB
Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive Schwann cell-derived sarcomas and are the leading cause of mortality in patients with neurofibromatosis type 1 (NF1). Current treatment modalities have been largely ineffective resulting in a high rate of MPNST recurrence and poor five year patient survival. This necessitates the exploration of alternative chemotherapeutic options for MPNST patients. By evading apoptosis and utilizing protective mechanisms such as autophagy, cancer cells develop resistance to chemo- and radio-therapy. The overall goal of my thesis studies is to evaluate chemotherapeutic agents that can modulate both apoptosis and autophagy, thus target both cell death pathways …
