Blood Pressure And Tobacco Exposure Among Rural Adolescents Ages 15-18, Luz Huntington-Moskos
Blood Pressure And Tobacco Exposure Among Rural Adolescents Ages 15-18, Luz Huntington-Moskos
All ETDs from UAB
High blood pressure is a prevalent precursor to cardiovascular disease. An estimated 3% of US adolescents have hypertension. In addition, prehypertension is predictive of hypertension in adolescents, with progression between these stages at approximately 7% per year. Tobacco use/exposure is strongly linked to cardiovascular risk and disease in adults. Further, rural communities have higher tobacco use prevalence and fewer community policies restricting tobacco use. Little is known about the effects of tobacco exposure on blood pressure and the mediating effects of inflammation (salivary C-reactive protein (CRP)) in rural adolescents. The purpose of this study is to determine the relationships between …

Insulin resistance (IR) is central to the pathogenesis of cardiometabolic disorders. Early detection, along with appropriate interventions, is paramount to reduce the morbidity and mortality of IR-related diseases. The gold standard measurement for IR is the hyperinsulinemic-euglycemic clamp, which is markedly sophisticated for clinical evaluation but costly and invasive for clinical practice. Several alternative surrogate indicators of IR have been identified and used by clinicians, including insulin sensitivity indices derived from plasma glucose and insulin values, as well as other indicators that are independent of direct insulin measurements. In addition, lipid panel and lipoprotein subclass profile have emerged as markers …

An expanding body of literature argues for a pivotal role of molecular epigenetic mechanisms in memory. Defined as mechanisms that regulate gene expression in the absence of DNA sequence modifications, these regulate various stages of memory-associated transcription. These phenomena are present at diverse anatomical subregions of the central nervous system (CNS) and regulate corresponding behaviors. Epigenetic mechanisms comprise a unique category of behavioral and physiological modulators because of their potential to modify the cellular phenotype in a stable manner. Hence, epigenetics offers a novel potential solution to a central paradox in memory retention: the finding that most putative molecular substrates …
The Relationship Of Religiosity, Spirituality And High-Risk, Rev Tommie Lee Watkins Jr
The Relationship Of Religiosity, Spirituality And High-Risk, Rev Tommie Lee Watkins Jr
All ETDs from UAB
Religion and spirituality are important concepts for many Black MSM. While many social factors may be associated with the increasing disparity of HIV infection among Black MSM, high levels of religiosity and spirituality prevalent in Black culture may be correlated with high risk behavior among Black MSM and may help explain this population's increasing incidence of HIV infection. Research supports a relationship between religiosity, spirituality, and high risk behavior among populations. Some research has suggested that religiosity and spirituality among Black MSM may be correlated but are multifaceted constructs. Conclusions suggest that among Black MSM these constructs account for certain …
Photothermal Desorption Of Toluene From Single Walled Carbon Nanotube And Activated Carbon Sorbents, Evan Lee Floyd
Photothermal Desorption Of Toluene From Single Walled Carbon Nanotube And Activated Carbon Sorbents, Evan Lee Floyd
All ETDs from UAB
Millions of workers are occupationally exposed to volatile organic compounds (VOC) annually, requiring exposure assessments through air sampling. Reducing time to knowledge while maintaining adequate sensitivity and affordability is a constant struggle. Sorbent sampling is the preferred technique for VOC exposure assessments. Chemical desorption of sorbents is the most common desorption technique, but sensitivity is limited due to the small injection fraction. Thermal desorption has excellent sensitivity, but provides only one analysis per sample and is cost prohibitive. The goal of this dissertation was to develop a desorption technique that bridges the sensitivity gap between chemical desorption (0.1%) and thermal …
Potential Roles Of The Immunostimulatory Signals Il-15 And Mica In Oncolytic Hsv-1 Therapy For Malignant Glioma, David Curtis Gaston
Potential Roles Of The Immunostimulatory Signals Il-15 And Mica In Oncolytic Hsv-1 Therapy For Malignant Glioma, David Curtis Gaston
All ETDs from UAB
Malignant gliomas are the most frequently diagnosed and the most fatal primary brain tumors. Innovative therapeutic approaches are necessary to combat these devastating cancers, and oncolytic herpes simplex virus type-1 (oHSV) deleted of the γ134.5 neurovirulence gene is a promising adjunctive therapy. The primary mechanism of tumor clearance by oHSV is lytic replication specifically within malignant cells. oHSV also stimulates tumor infiltration of cytotoxic immune effector cells that can participate in tumor clearance. However, cytotoxic immune cells target oHSV as well as tumor, which may limit therapeutic efficacy. Further knowledge regarding the nature of these interactions and how the interactions …
Sulindac Sulfide Amide As A Novel Agent For The Prevention And Treatment Of Lung Cancer, Evrim Gurpinar
Sulindac Sulfide Amide As A Novel Agent For The Prevention And Treatment Of Lung Cancer, Evrim Gurpinar
All ETDs from UAB
Nonsteroidal anti-inflammatory drugs (NSAIDs) such as sulindac sulfide (SS) have shown promising antineoplastic activity in multiple tumor types, but toxicities resulting from cyclooxygenase (COX) inhibition limit their use in cancer prevention. We recently described a N,N-dimethylethyl amine derivative of SS, sulindac sulfide amide (SSA), that does not inhibit COX-1 or -2, yet displays potent tumor cell growth inhibitory activity. Here, we studied the basis for the growth inhibitory effects of SSA on human lung adenocarcinoma cell lines and evaluated its preclinical pharmacology. SSA potently inhibited the growth of lung tumor cells with IC50 values of 2-5 μ compared with 44-52 …
Therapeutic Potential Of Genetically-Engineered Mesenchymal Stem Cells In Multiple Myeloma, Jerome T. Higgs
Therapeutic Potential Of Genetically-Engineered Mesenchymal Stem Cells In Multiple Myeloma, Jerome T. Higgs
All ETDs from UAB
ABSTRACT Multiple Myeloma (MM) remains the second most common hematologic malig-nancy occurring in adults, which primarily affects the skeletal system causing severe bone destruction, spinal cord compression and hypercalcemia. Current therapies, which include chemotherapy, radiotherapy, autologouos stem cell transplantation and in some cases surgery, have extended the median survival between 3 and 10 years. However, MM is still incurable and therefore improving current therapies or developing newer ones to reduce the burden of osteolytic damage and extend survival rate will be highly beneficial for patient management. The long-term goal of this study is to develop a novel therapeutic approach to …
Genetic And Biochemical Characterizations Of The Capsular Glycosyltransferases In Streptococcus Pneumoniae Serotype 2, David Boyd Anthony James
Genetic And Biochemical Characterizations Of The Capsular Glycosyltransferases In Streptococcus Pneumoniae Serotype 2, David Boyd Anthony James
All ETDs from UAB
The principle objective of this dissertation is to develop a thorough understanding of the genetics and biochemistry of capsule synthesis. Specifically, it involves the identification and characterization of the capsular glycosyltransferases in Streptococcus pneumoniae serotype 2, with investigations into their regulation. S. pneumoniae (the pneumococcus) is a significant human pathogen that has the ability to persist as a commensal and then transition to a virulent state, the latter of which is a major contributor to global morbidity and mortality. The capsular polysaccharide (CPS) of S. pneumoniae is a protective surface structure that plays an integral role in this disease process. …

Human Immunodeficiency Virus (HIV) is one of the leading infectious diseases in the world. In spite of substantial progress in the advancement of antiretroviral therapy for HIV treatment, new infections outpace the number of infected persons initiating ART. Therefore, the prevention of HIV remains a crucial health issue. Pre-Exposure Prophylaxis, (PrEP), which involves using one or more antiretroviral agents to reduce the risk of HIV infection prior to potential exposure, has shown effectiveness at reducing HIV transmission in study volunteers with different sexual orientation around the world. The clinical pharmacology of antiretroviral drugs, specifically tenofovir (TFV) and emtricitabine (FTC), in …
Marcks Is A Regulator Of Growth, Radiation Sensitivity And Is A Novel Prognostic Factor For Glioblastoma Multiforme, John Jarboe
Marcks Is A Regulator Of Growth, Radiation Sensitivity And Is A Novel Prognostic Factor For Glioblastoma Multiforme, John Jarboe
All ETDs from UAB
Glioblastoma multiforme (GBM) is the most common and deadly primary brain malignancy necessitating improved understanding of GBM biology. In this study, we explore the role of Myristoylated Alanine Rich C-Kinase Substrate (MARCKS) in the context of GBM. We have discovered that the MARCKS protein regulates GBM growth as well as response to radiation therapy through its effects on proliferation, senescence, and DNA repair based on our studies in cell culture and in patient-derived xenograft tumors implanted in mice. Importantly, our analysis of clinical patient data demonstrates that MARCKS is an independent predictor for outcome in GBM patients. Indeed, high MARCKS …

Usp49 And H2b Deubiquitination In Chromatin And Cellular Function, Amanda E. Jones
All ETDs from UAB
Histones are globular proteins which help package and organize DNA in the eukaryotic nucleus. The four core histones, H2A, H2B, H3 and H4, combine with approximately 146 base pairs of DNA to form a nucleosome, the fundamental unit of chromatin. Post-translational modifications to the C-terminal and N-terminal histone tails regulate chromatin structure and function, and play important roles in transcriptional regulation, replication, DNA damage response, and mRNA processing. Histone H2B ubiquitination is an evolutionarily conserved modification with roles in gene expression and DNA damage repair. In addition, H2B ubiquitination may also regulate mRNA splicing. Here, we identify USP49, a cysteine …

The Effect Of An Intensive Oral Hygiene Regimen On Gingival Inflammation During Pregnancy: Clinical And Laboratory Analysis, Maninder Kaur
All ETDs from UAB
Background: Recent evidence suggests that systemic inflammation as host immune response to oral microbial challenge may well underlie the observed association between periodontal disease and preterm birth/low birth weight (PTB/LBW). The aim of this pilot study was to evaluate the effect of vigorous oral hygiene regimen on gingival inflammation and gingival crevicular fluid (GCF)/serum biomarkers (TNF-&alpha, IL-1&beta and IL-6) during pregnancy and its impact on pregnancy outcome. Methods: 120 participants with pregnancy between 16-24 weeks gestation and with gingival index (GI) scores &ge 2 at &ge 50 % of tooth sites were recruited from the available pool of patients at …
The Impact Of Weight Status On The Adoption Of Self-Care Behaviors Among Heart Failure Patients, Bern'nadette Knight
The Impact Of Weight Status On The Adoption Of Self-Care Behaviors Among Heart Failure Patients, Bern'nadette Knight
All ETDs from UAB
Self-care is a major component of heart failure management. Excess weight is a disease that may negatively affect a patient's ability to effectively practice self-care. The project aimed to assess 1) the relationship between weight status and heart failure self-care behaviors and 2) the modification of the relationship between social support and heart failure self-care by weight status. This cross sectional study utilized baseline data from a cohort of African-American and Caucasian participants diagnosed with heart failure. The heart failure cohort was formed from three larger studies (n=690) designed to assess the relationships among social support, self-care behaviors and hospital …
Hard On Your Heart: A Qualitative Description Of Adolescent Prenatal Stress, Candace Clayton Knight
Hard On Your Heart: A Qualitative Description Of Adolescent Prenatal Stress, Candace Clayton Knight
All ETDs from UAB
Introduction: Pregnancy during adolescence is potentially stressful due to the concurrent tasks of navigating the typically tumultuous adolescent stage of development and the life altering experience of pregnancy (Kaye, 2008). There is a growing body of research linking prenatal stress to poor birth and developmental outcomes such as premature birth and low birth weight infants (K. Keenan, Sheffield, & Boeldt, 2007; Mulder et al., 2002), which makes describing the relatively unexplored perceptions and experience of stress during adolescent pregnancy important. The life course framework, with its emphasis on social, environmental, and family risk factors, has implications for reducing disparities among …

Investigation Of Death Receptor-5 Mediated Apoptosis And Inhibition Of Wnt/Ss-Catenin Signaling In Basal-Like Breast Cancer Stem Cells, Angelina Ix-Ik' Londono-Joshi
All ETDs from UAB
Basal-like breast cancers (BLBC) display aggressive clinical behavior attributed to the presence of cancer stem cells (CSCs). TRA-8, a monoclonal antibody that binds specifically to TRAIL death receptor 5, preferentially induces apoptosis in BLBC subtype cells; however it is unknown if TRA-8 is also cytotoxic to the CSC population. Moreover, some BLBC cell lines are resistant to TRA-8, and overcoming resistance is critical for clinical translation of this therapy. One potential approach to overcome TRA- 8 resistance is to target the Wnt/ß-catenin pathway. LRP6 is a cell surface receptor that is an indispensable element of the Wnt/ß-catenin signaling pathway that …

Characterizing The Roles Of Il-11 And Cd68 In Breast Cancer Bone Metastasis, Erin Mills Mccoy
All ETDs from UAB
The molecular mechanisms regulating the preferential metastasis of breast cancer to bone have not been fully elucidated, but it is hypothesized that local conditions in the bone create an environment conducive to colonization by breast cancer cells and that the breast cancer cells interact directly with cells in the bone. In this dissertation, two goals were pursued: (1) to explore breast cancer secreted interleukin (IL)-11's role on osteoclast function and (2) investigate the expression and potential role of CD68 in breast cancer adhesion to bone. Higher rates of bone metastasis occur in human breast cancer tumors expressing IL-11, a cytokine …

Apparent Change In Obesity-Mortality Associations: Methodological Issues In Survival Analyses With Censored Outcomes, Tapan Shirish Mehta
All ETDs from UAB
Analyses of the National Health and Nutrition Examination Survey (NHANES) have suggested that the mortality rate (MR) associated with obesity has decreased over calendar time. However, there has been conflicting evidence about the apparent change in the obesity-MR over calendar time. This dissertation investigates some of the empirical and methodological issues involved in assessing the longitudinal change in the obesity-mortality associations. In the first manuscript, Obesity and Mortality: Are the Risks Declining? Evidence from Multiple Prospective Studies in the U.S., a multiple longitudinal design is proposed and implemented to evaluate whether the obesity-mortality associations have declined over calendar time after …

Phenotypic Analysis Of B Cells In Hla*B44 Positive Patients That Exhibit Common Variable Immunodeficiency And Recurrent Sino-Pulmonary Infections, Eva Szymanska Mroczek
All ETDs from UAB
Depressed serum immunoglobulin levels and recurrent sinopulmonary infections mark Common Variable Immune Deficiency (CVID). Many family members of CVID patients also suffer Recurrent Sino-Pulmonary Infection (RESPI) but have normal serum immunoglobulins. We identified HLAB44 positive identical female twins who suffer sinopulmonary infections and are discordant for CVID and RESPI. Flow cytometry subsets showed equivalent numbers of immature B cells (BC) in both twins, but lower numbers of transitional and mature BC in the CVID twin. Presented is an in-depth comparison of V (D) J gene usage, hydrophobicity, length, DH reading frame, and amino acid usage between µ H chain repertoires …
Neuropathological Alterations In Alzheimer's Disease: An Up Close Look At Sympathetic Sprouting, Amy Renee Nelson
Neuropathological Alterations In Alzheimer's Disease: An Up Close Look At Sympathetic Sprouting, Amy Renee Nelson
All ETDs from UAB
Pathological hallmarks of AD include neurofibrillary tau tangles, amyloid beta (Abeta) accumulation and cholinergic degeneration. Cholinergic degeneration can be mimicked in rats by lesioning cholinergic neurons in medial septum. Hippocampal cholinergic denervation disrupts retrograde transport of nerve growth factor (NGF), leading to its accumulation, which subsequently triggers sprouting of noradrenergic sympathetic fibers from the superior cervical ganglia into hippocampus. Dr. McMahon's lab previously reported that coincident with this sprouting, there is an increase in cholinergic innervation that correlates with a recovery of M1 muscarinic receptor dependent plasticity at CA3-CA1 synapses and visual cortex. These findings suggest that noradrenergic sympathetic sprouting …

Following the Process School of the Resource Based View, both internal and external information technology resources were examined to see how hospitals had responded to Federal policies related to the "meaningful use" of Health IT and Electronic Health records. Specifically, this study examined changes in information technology spending by hospitals based on size, hospital type, and percentage of revenue derived …
Microevolution Of Capsule Synthesis Genes Contributes To Pneumococcal Capsule Diversity, Melissa Beth Oliver
Microevolution Of Capsule Synthesis Genes Contributes To Pneumococcal Capsule Diversity, Melissa Beth Oliver
All ETDs from UAB
Streptococcus pneumoniae (pneumococcus) is an important human pathogen that expresses a capsular polysaccharide (PS) to shield underlying antigenic structures from complement-mediated opsonophagocytosis. Thus, capsular PS is the major virulence factor, the target of primary immune responses to pneumococcal infections, and the antigenic component of pneumococcal vaccines. Pneumococci have diverse capsular PS synthesis (cps) loci and express over 90 different capsule types. Such diversity helps pneumococci escape immune detection and adapt to changing environments. Recombination of cps genes has been recognized as the main driver of capsule diversity. However, we show point mutations in cps genes encoding glycosyltransferases can broaden enzymes' …

A Study Of Multi-Group And Multivariate Tests Of Equivalence With Application To Microarray And, Celeste Yang
All ETDs from UAB
In this dissertation we have adapted two multi-group equivalence tests to be performed on high-dimensional data. The F and Range test for multi-group equivalence were applied to the public microarray dataset GSE11291 to detect equivalently expressed genes. They were also evaluated in terms of type I error and power using single gene simulation and a high-dimension simulation. The F test has higher power than the Range for the same simulated data and parameter settings, in the single gene simulations. The power of the two tests is similar in the high-dimension simulation. The multi-group equivalence tests that were applied to the …

High-Tech Services And Hospital Performance In The United States, Ferhat Devrim Zengul
All ETDs from UAB
This dissertation examined the relationship between high-technology medical services and hospital performance by focusing on financial and quality performance dimensions. An initial systematic review disclosed the paucity of research and mixed findings about the technology-performance relationship. The review indicated the need for further analyses by emphasizing some limitations of existing studies. The resource-based view (RBV) of a firm was used as a conceptual framework in examining the relationship between high-tech medical services and hospital financial performance. It was hypothesized that large breadth (number) of high-tech services and the use of rare high-tech services would be positively associated with hospitals' financial …
Regulation Of Stim1 By O-Glcnacylation In Cardiomyocytes, Xiaoyuan Zhu-Mauldin
Regulation Of Stim1 By O-Glcnacylation In Cardiomyocytes, Xiaoyuan Zhu-Mauldin
All ETDs from UAB
In non-excitable cells, STIM1 and Orai1 are the primary mediators of store-operated Ca2+ entry (SOCE); however little is known about their roles in cardiomyocyte Ca2+ handling. We have previously shown that acute increases in the levels of O-GlcNAcylation (the attachment of O-linked N- acetylglucosamine (O-GlcNAc) to target proteins) are cardioprotective through attenuating Ca2+-mediated injury and increased O-GlcNAcylation blunts SOCE in cardiomyocytes. Therefore, the goals here were to determine the regulation of STIM1 and STIM1-mediated SOCE by O-GlcNAcylation in cardiomyocytes. Immunohistochemical analysis demonstrated the co-localization of STIM1 with SERCA and RyR in adult cardiomyocytes. NRVMs were transfected with the eYFP-tagged STIM1 …
The Relationship Of Maternal Depressive Symptoms Among First Time Adolescent And Adult Mothers And Their Safe Parenting Practices And Child Injuries, Angela Warren Baumann
The Relationship Of Maternal Depressive Symptoms Among First Time Adolescent And Adult Mothers And Their Safe Parenting Practices And Child Injuries, Angela Warren Baumann
All ETDs from UAB
Maternal depressive symptoms have been associated with deficits in parenting practices that protect children from injuries; however, few studies have been conducted to examine these relationships. Using data from a multisite longitudinal study of 252 first-time mothers, the relationships between the use of safe parenting practices and maternal depressive symptoms was examined, taking into account mother's resources (as defined by age and education level) and race at five time points during the first 3 years of the child's life. Depressive symptoms were assessed using the Beck Depression Inventory. Measures of maternal depressive symptoms, safe parenting practices (use of car seat, …
The Genetic Complexity Of The Human Fc-Gamma Receptor 1q23 Locus And Its Relationship To Autoimmunity, Travis Samuel Ptacek
The Genetic Complexity Of The Human Fc-Gamma Receptor 1q23 Locus And Its Relationship To Autoimmunity, Travis Samuel Ptacek
All ETDs from UAB
The human immune system must be able to adapt to a wide spectrum of invading pathogens in order to keep the human body alive. This variation includes directed recombination and mutation at the level of the individual and genetic variation and natural selection at the population level. A direct consequence of the adaptability of the immune system is autoimmunity: as the immune system adapts to a shifting spectrum of antigens, it can shift to self-antigens, and therefore attack the body and cause disease. Since genetic factors are part of this adaptability, they are also connected with autoimmune disease. SLE is …
The Role Of Complement In Experimental Cerebral Malaria, Theresa N. Ramos
The Role Of Complement In Experimental Cerebral Malaria, Theresa N. Ramos
All ETDs from UAB
Cerebral malaria (CM) is one of the most severe clinical complications of P. falciparum malaria with a fatality rate of 15-30%, and 10% of CM survivors have permanent neurological sequelae. Since inflammation is a central pathophysiological tenet of CM, we began examining the role of the complement system in pathogenesis of experimental cerebral malaria (ECM) using Plasmodium berghei ANKA (PbA) model. Previous studies using this model indicated that mice naturally deficient in complement component C5 were protected from cerebral complications, and wild type mice treated with anti-C5aR antibody were also protected. To determine the protective mechanism of naturally-C5 deficient mice, …

Methods A secondary data analysis was performed on data obtained from the home healthcare agency. A total of 4,717 unique patients found in the data set. Some patients were represented in the data more than once during the observation period. To examine the relationship …
Regulation Of Glioma Cell Migration And Proliferation By A Non-Selective Cation Channel., Arun Kumar Rooj
Regulation Of Glioma Cell Migration And Proliferation By A Non-Selective Cation Channel., Arun Kumar Rooj
All ETDs from UAB
Two of the most striking features of brain tumors are their unusual ability to robustly proliferate and migrate in the brain. Previous results from our laboratory suggest that glioma cells express a non-selective cation channel that is composed of Epithelial Sodium Channel (ENaC) and Acid Sensing Ion Channel (ASIC) subunits. We hypothesize that this glioma specific current regulates glioma cell migration and proliferation by modulating an intracellular signaling pathway. To test our hypothesis, we have attenuated this cationic conductance by either pharmacological blockers (psalmotoxin-1 and benzamil), or by knocking down expression of a particular subunit of this cross-clade ion channel …
