Ego Depletion: Buffering Through Touch, Victoria E. Forgea Jan 2019

Ego Depletion: Buffering Through Touch, Victoria E. Forgea

College of Graduate Studies: Theses & Dissertations

Ego depletion theory states that self-control is tied to a limited resource and diminishes after repeated exertions; consequently, the current study sought to examine how to replenish self-control through touch. Due to the positive outcomes of touch, we expected touch to allow participants to persist longer on a geometric tracing puzzle task after becoming ego depleted. The current study implemented measures widely used in the ego depletion literature, and the experimenter implemented two brief touches to examine the effects of touch in the domain of self-control. We found that participants who received touch persisted significantly longer on the geometric tracing …

Pain, Severity, And Attentional Capacity Following Acute Musculoskeletal Injury, Rebekah F. Roessler Jan 2019

Pain, Severity, And Attentional Capacity Following Acute Musculoskeletal Injury, Rebekah F. Roessler

College of Graduate Studies: Theses & Dissertations

Background: As recreational activities grow in popularity, there is a concurrent rise in musculoskeletal injury. Injury severity is determined through clinical evaluation and defined by a grading scale. Pain is included in the definition of each injury grade, despite the lack of any conclusive evidence relating injury severity and the associated pain. Additionally, previous studies report impairments in cognitive performance due to chronic and acute pain. The aim of this study is to determine the relationship between the perceived pain intensity and the clinically diagnosed severity of an acute musculoskeletal injury, and to determine if attentional capacity is influenced by …

Effects Of Climate Variability: A Long-Term Perspective On Leaf Litter Processing In The Ogeechee River, Jose A. Sanchez Jan 2019

Effects Of Climate Variability: A Long-Term Perspective On Leaf Litter Processing In The Ogeechee River, Jose A. Sanchez

College of Graduate Studies: Theses & Dissertations

The Intergovernmental Panel for Climate Change (IPCC) predicts a rise in temperatures and changes to precipitation patterns for the 21st century. These changes are expected to lead to a higher frequency of extreme events such as drought and floods which lead to the alteration of the hydrology, communities, and processes of freshwater ecosystems. Leaf litter decomposition in stream ecosystems is an important component of the energy and nutrient cycle representing a food source for aquatic organisms. This has made it a tool for assessing long term responses to disturbance due to changes in the assemblage of macroinvertebrates that …

Dependence Measure For Length-Biased Survival Data Using Copulas, Rachid Bentoumi, Mhamed Mesfioui, Mayer Alvo

All Works

© 2019 Rachid Bentoumi et al., published by De Gruyter 2019. The linear correlation coefficient of Bravais-Pearson is considered a powerful indicator when the dependency relationship is linear and the error variate is normally distributed. Unfortunately in finance and in survival analysis the dependency relationship may not be linear. In such case, the use of rank-based measures of dependence, like Kendall's tau or Spearman rho are recommended. In this direction, under length-biased sampling, measures of the degree of dependence between the survival time and the covariates appear to have not received much intention in the literature. Our goal in this …

Effects Of A Sensory Diet On Attention And Participation In Children With Autism, Leighanne Smith-Mrkaja Jan 2019

Effects Of A Sensory Diet On Attention And Participation In Children With Autism, Leighanne Smith-Mrkaja

Theses and Dissertations

This applied dissertation was designed to provide initial knowledge regarding sensory diets and sensory-based interventions. The need for classroom-based sensory interventions are not always considered, especially with the high number of students diagnosed with ASD at the researcher’s school. Often sensory intervention may not be considered educationally relevant, especially in the prekindergarten level. With the proper training and materials, as well as the guidance of the school-based occupational therapist, teachers, other therapists, classroom assistants, parents, and school-based staff might be able to utilize sensory-based activities like sensory diets to increase participation, positive behaviors, and attention. The following applied research study …

© 2013 IEEE. Testing is a vital component of the system development life cycle. As information systems infrastructure move from native computing to cloud-based and virtualized platforms, it becomes necessary to evaluate their effectiveness to ensure completion of organizational goals. However, the complexity and scale of virtualized environments make this process difficult. Additionally, inherited and novel issues further complicate this process, while relatively high costs can be constraining. Enabling service-driven environments to provide this evaluation is therefore beneficial for both providers and users. No such complete service offering currently exists. This paper is therefore aimed to benefit industry and academia …

Regulation Of Intestinal Innate Lymphoid Cells In Acute And Chronic Inflammation, Sarah Dulson Jan 2019

Regulation Of Intestinal Innate Lymphoid Cells In Acute And Chronic Inflammation, Sarah Dulson

All ETDs from UAB

The Innate Lymphoid Cell (ILC) population encompasses five subpopulations that are increasingly appreciated to participate in immune responses to inflammation and injury as well as directly influence homeostasis in tissues throughout the body. ILCs are enriched at mucosal surfaces, such as the gastrointestinal tract, where they are transcriptionally poised for rapid activation. Therefore, ILCs contribute significantly to protective responses to infection, and can exacerbate inflammation and disease when dysregulated. Herein, we demonstrate two pathways that regulate intestinal ILC phenotype and function and delineate the impact of these pathways on both protective and pathogenic roles of ILCs. Using a murine model …

Impact Of Familial Chronic Illness On Adolescent Somatization, Lindsey Elliott Jan 2019

Impact Of Familial Chronic Illness On Adolescent Somatization, Lindsey Elliott

All ETDs from UAB

Somatic symptoms, or physical symptoms that do not have an identifiable organic etiology, have a prevalence of 10-30% in children. They have been associated with poor psychosocial outcomes in children, including emotional and behavioral problems, school absences, and impaired social functioning. Further, these symptoms represent a burden on the health care system as patients with somatic symptoms are frequent users of both primary care physicians and specialists. The etiology of somatic symptoms is thought to be due to a combination of biological, psychological, interpersonal, and healthcare factors. Two theories exist regarding the etiology of somatic symptoms. Brown’s integrative conceptual model …

Bet Bromodomain Inhibition As An Approach For Treatment Of Cholangiocarcinoma, Samuel Charles Fehling Jan 2019

Bet Bromodomain Inhibition As An Approach For Treatment Of Cholangiocarcinoma, Samuel Charles Fehling

All ETDs from UAB

Cholangiocarcinoma (CCA) is a highly aggressive neoplasm which arises from the epithelial layer of the biliary tract. It is the second most common primary hepatic malignancy. As CCA is typically diagnosed at late disease stage, the current standard of care, resection followed by gemcitabine with cisplatin, is not effective. Further, up to 90% of CCA patients are ineligible for resection. Of those eligible for resection, postoperative chemotherapy does not prolong overall survival leading to a 5-year survival of ~30%. Previously, mutations have been identified in KRAS (17% of CCA cases), TP53 (44%) and SMAD4 (17%) but none have been recognized …

Evaluation Of A Novel Monoclonal Antibody Based Therapy For Neuroendocrine Tumors, Daniel Flanigan Jan 2019

Evaluation Of A Novel Monoclonal Antibody Based Therapy For Neuroendocrine Tumors, Daniel Flanigan

All ETDs from UAB

Neuroendocrine tumors (NETs) are malignancies that arise from genetic or sporadic abnormalities in the endocrine system. These cancers can be found in various organ systems but are most frequently expressed in the gastrointestinal (GI) tract and pancreas. The incidence rate of NETs has been steadily increasing in the past few decades, exhibiting a 6.4-fold increase from 1973 to 2012. Despite this observation, these cancers are still considered rare and as such there is a lack of appropriate treatments addressing them. Monoclonal antibodies (mAbs) that specifically bind to type 2 somatostatin receptor (SSTR2), a protein commonly overexpressed in NETs, could be …

Baf Chromatin Landscaping During Bone Formation And Maintenance, Tanner Cole Godfrey Jan 2019

Baf Chromatin Landscaping During Bone Formation And Maintenance, Tanner Cole Godfrey

All ETDs from UAB

Bone loss is a worldwide problem resulting in increased risk of fracture. Osteoblasts are responsible for bone synthesis; therefore, treatments promoting osteoblast differentiation and/or activity would result in increased bone formation. The regulation of DNA accessibility is a key mechanism controlling gene expression and cellular differentiation. BAF (BRG1 Associated Factor) mediated chromatin remodeling increases DNA accessibility by sliding or ejecting nucleosomes. This process can occur in a cell type specific manner based on the composition of BAF. In many tissue types, a unique combination of BAF subunits has been identified to be responsible for the maintenance or differentiation of that …

Integration Of Cone Photoreceptor Signals In Macaque Lgn Neurons, Paul B. Brown Jan 2019

Integration Of Cone Photoreceptor Signals In Macaque Lgn Neurons, Paul B. Brown

All ETDs from UAB

Despite advances in the understanding of the primate visual system, much is yet to be learned about the way light signals sum to create our perception of the world. This is especially true at the simplest level of visual processing—the summation of two individual cone photoreceptor signals. How such signals combine to create visual perception has not been assessed in vivo. We used an adaptive optics scanning laser ophthalmoscope (AOSLO) to deliver binarized noise movies to identified groups of cones within the receptive fields of neurons in the macaque lateral geniculate nucleus (LGN). Recordings of neural action potentials within the …

The Impact Of Redox Stress In Primary Hyperoxaluria Type 1, Brianna Buchalski Jan 2019

The Impact Of Redox Stress In Primary Hyperoxaluria Type 1, Brianna Buchalski

All ETDs from UAB

Primary Hyperoxaluria (PH) is a family of three inborn errors of glyoxylate metabolism resulting in endogenous oxalate overproduction. PH1 is the most common and most severe form of the disorder when compared to PH2 and PH3. PH1 can result in systemic oxalosis or end stage renal disease, and there is currently no cure for this disorder. The only curative treatment is combined liver/kidney transplant. The difficulty in defining a cure for the disorder arises from poor knowledge of the sources of endogenous oxalate and a lack of understanding in the underlying pathophysiology of the disorder. For these reasons, we have …

Receptor Sialylation By St6gal-I Promotes Tumor Progression By Enhancing Tumor Cell Survival And Epithelial To Mesenchymal Transition, Colleen Maeve Britain Jan 2019

Receptor Sialylation By St6gal-I Promotes Tumor Progression By Enhancing Tumor Cell Survival And Epithelial To Mesenchymal Transition, Colleen Maeve Britain

All ETDs from UAB

The upregulation of a certain subset of glycosyltransferases was an early marker for cancer development. Specifically, ST6Gal-I, which adds an α2-6 linked sialic acid to N-glycans on proteins bound for the plasma membrane or secretion, is selectively upregulated upon malignant transformation. Our laboratory has shown that ST6Gal-I is implicated in many facets of tumor biology and is an important mediator of tumorigenesis. For example, ST6Gal-I activity promotes the survival of cells when challenged with hypoxia, FasL, or TNFα, confers resistance to chemotherapeutics, enhances tumor cell migration and invasion, and fosters a cancer stem cell phenotype. The work presented in this …

Context Fear Memory Formation Is Regulated By Hippocampal Lncrna-Mediated Histone Methylation Changes, Anderson Alan Butler Jan 2019

Context Fear Memory Formation Is Regulated By Hippocampal Lncrna-Mediated Histone Methylation Changes, Anderson Alan Butler

All ETDs from UAB

The post-translational modification of histones regulates gene expression and is critical for the formation and maintenance of hippocampus-dependent long-term memories. Changes in gene-specific expression of various epigenetic marks during the aging pro-cess are sufficiently consistent as to be used as an aging landmark or epigenetic clock in both humans and other species; however, the molecular mechanisms which govern the application of these marks aging are poorly explored. Recently, long noncoding RNAs (lncRNAs) have been implicated as regulators of histone methyltransferases and other chromatin-modifying enzymes (CMEs). Despite the relevance of such mechanisms to both aging and memory formation, the behavioral relevance …

Significance Of Acculturation, Assimilation, And Allostatic Load As Risk Factors For Obesity Among Hispanics, Yenni Elvia Cedillo Juare

All ETDs from UAB

Obesity has increased during the last two decades in the United States (U.S.) and is considered a major risk factor for chronic diseases within the Hispanic community. The burden of obesity in Hispanics is associated with higher rates of morbidity and mortality and an increase in healthcare costs. Hispanics’ challenges after migration extend to subsequent generations, putting the population at risk for disease development. Specifically, migration can lead to the adoption of health behaviors, beliefs, values, and language of the host country, a process known as acculturation, which has been associated with changes in health behaviors. Among the Hispanic population, …

Personal, Environmental, And Behavioral Factors Of Condom Use Among African American Adolescent Males, Jessica Thames Chambliss

All ETDs from UAB

Risky sexual behaviors among adolescents increase the negative outcomes of the occurrence of an unplanned pregnancy and contracting or transmitting disease. Adoles- cents that engage in risky sexual activities are at greater risk for adverse health and social outcomes. Unfortunately, the impact of pregnancy and sexually transmitted infections (STIs) among adolescents is far-reaching and does not only affect the immediate individuals. Despite a decline in teen pregnancy and birth rates, the diagnosis of STIs is steadily increasing among adolescents. Moreover, African American adolescent males in the United States and specifically in Alabama are disproportionally more at risk for STIs. Additionally, …

Mechanisms Of Acute Kidney Injury: The Role Of Ferritin Heavy Chain In Renal Heme-Unology, Laurence Marie Black Jan 2019

Mechanisms Of Acute Kidney Injury: The Role Of Ferritin Heavy Chain In Renal Heme-Unology, Laurence Marie Black

All ETDs from UAB

The kidneys are complex, multi-faceted organs that are responsible for regulatory processes, such as fluid homeostasis, hormone production, blood pressure regulation, and systemic toxin removal. Sudden disruption of these processes by acute kidney injury (AKI) causes rapid decline in renal function as well as significant morbidity and mortality. AKI is a significant clinical concern, affecting up to 13.3 million people globally each year and has the propensity to progress to chronic kidney disease (CKD), though the mechanism remains undefined. One reason for this is due to the lack of understanding of models used to study both AKI and CKD, hindering …

Characterization Of Chemical Uptake And Aryl Hydrocarbon Receptor Mutations In Zebrafish, Jaclyn Paige Souder Jan 2019

Characterization Of Chemical Uptake And Aryl Hydrocarbon Receptor Mutations In Zebrafish, Jaclyn Paige Souder

All ETDs from UAB

In a society driven by technology and industry, we must be increasingly aware of how changes to our environment impact our health. This is especially true concerning embryonic development, which is easily influenced by extra-embryonic factors, including environmental contaminants. Determining how exogenous compounds are absorbed, which receptors they act through, and how these receptors act endogenously is important to fully understand to what extent developmental exposures impact fetal and adult health. I have used the zebrafish model system to address these questions for two classes of environmentally-relevant chemicals—estrogens and dioxins. First, I developed an assay to measure the uptake of …
