All ETDs from UAB
This narrative ethnographic research study focused on the personal and schooling stories and counter-stories of three Latina teachers living and teaching in the Deep South. Using three contemporary young adult literature texts written by Latina authors, this three-month short term narrative ethnographic study sought to explore the lived experiences of three Latina teachers in the Deep South by way of testimonios (Espino, Munoz, and Kiyama, 2010) imbued with muxerista portraiture (Flores, 2017). The theoretical frameworks of LatCrit in education (Solorzano & Yosso, 2001) and Chicana/Latina Feminism guided every aspect of this study, which occurred during the global COVID-19 pandemic. Both …
An Investigation Of Strain And Support Needs Of Caregivers Of Older Adults With Delirium And Allied Health Promotion Interventions, Jasmine Vickers
An Investigation Of Strain And Support Needs Of Caregivers Of Older Adults With Delirium And Allied Health Promotion Interventions, Jasmine Vickers
All ETDs from UAB
Delirium, or the sudden onset of confusion, is common, highly distressing, debilitating, and deadly among hospitalized older adults and is associated with adverse outcomes for their family caregivers. As people are living longer with more complex conditions, more people will face the task of caregiving for older adults with delirium. Family caregivers can make meaningful contributions to delirium care, but high distress, insufficient knowledge, and lack of skills often seen in caregivers can lead to maladaptation and negative health outcomes. A few studies have focused on distress in caregivers from witnessing delirium episodes; however more research is needed to understand …

Chemical dispersants are fast becoming the most widely used tool in the remediation of spilled oil. The sheer magnitude of the Deepwater Horizon oil spill necessitated the use of multiple forms of remediation at scales never attempted. As a result, there is a critical need to understand how the spill and ensuing cleanup efforts impacted the surrounding ecosystem and its inhabitants. The goal of this research is to better understand the impact of the chemical dispersant (Corexit®EC9500A) on a key ecological and economic species, the blue crab (Callinectes sapidus), in the Gulf of Mexico. The first part of my dissertation …
Beyond Apoptosis: Insight Into The Complex Intracellular Networks That Govern Cell Fate, Hayley Neal Widden
Beyond Apoptosis: Insight Into The Complex Intracellular Networks That Govern Cell Fate, Hayley Neal Widden
All ETDs from UAB
The determination of cell fate is a dynamic process regulated by hundreds of proteins that converge into complex cell signaling pathways. Upon irreparable intracellular stress, a cell undergoes programmed cell death, a process known as intrinsic apoptosis. Apoptosis is regulated by the Bcl-2 family, a class of proteins that act either as pro-survival or pro-death signaling molecules. Due to the oncogenic upregulation of pro- survival Bcl-2 family proteins across human cancer cell types, a novel class of small molecule inhibitors called ‘BH3-mimetics’ have emerged as promising anti-cancer therapeutics currently under clinical investigation. Here, we highlight the crosstalk between anti-apoptotic Bcl-2 …
Importance Of The Zebrafish Model For Understanding Nutrition, Michael Britt Williams
Importance Of The Zebrafish Model For Understanding Nutrition, Michael Britt Williams
All ETDs from UAB
The common zebrafish Danio rerio is a useful model for human health. Effective utilization of this model required development of husbandry and reproductive protocols as well as genomic sequencing and creation of relevant molecular techniques. However, the dietary needs of the species remain woefully under investigated. At this time no chemically-defined open source diets are available to the zebrafish research community. Consequently, those labs utilizing the zebrafish model rely on commercial diets that may not provide adequate nutrition and lack consistency needed for rigorous and reproducible research. The first focus of these studies was to examine the current state of …
Miniaturization Of The Network Analyzer As An Interface Circuit For Wearable Resonance-Based Sensors, Fan Wu
Miniaturization Of The Network Analyzer As An Interface Circuit For Wearable Resonance-Based Sensors, Fan Wu
All ETDs from UAB
Readout interface circuits are the essential part of all sensor units. Miniaturing such circuits is a challenging design issue for the future of the Internet of Things, wearable and implantable biomedical devices, sensors for harsh environments, etc. For developing wireless telemetry sensors, Vector Network Analyzer (VNA) is a powerful measurement instrument that can measure scattering parameters (S-Parameters) of single and dual-port networks, as well as Y- and Z-parameters. However, VNAs are expensive and bulky and cannot be carried around, and therefore, they can’t be used as a sensor interface. This thesis aims to design, develop, and implement a miniaturized data …
Biological Pathways And Processes Underlying The Cardiac Regenerative Response Post-Injury In Small And Large Mammals, Eric Yang Zhang
Biological Pathways And Processes Underlying The Cardiac Regenerative Response Post-Injury In Small And Large Mammals, Eric Yang Zhang
All ETDs from UAB
Mammalian cardiomyocytes exit the cell-cycle shortly after birth. Consequently, the adult heart is unable to properly compensate for cardiac muscle lost to injury. As such, heart failure has remained the leading cause of death in the developed world for more than three decades. In this work, we illustrate our findings in using novel in-vivo animal models to examine two regenerative phenomena observed following myocardial injury:i.) neonate cardiomyocyte proliferation in large mammals ii.) the ‘paracrine effect’ as mediated by mesenchymal stromal cells In i.) we use a large animal model of myocardial injury during the early postnatal develop-mental stage to establish …

Fqhcs, Health Center Controlled Network Affiliation And Performance, Armika Jessica Berkley
All ETDs from UAB
Since the mid-1960s, Federally Qualified Health Centers (FQHCs) have been funded by the U.S. federal government to provide access to preventative and primary care for medically underserved communities. The federal government’s involvement in the funding of FQHCs was a response to extreme poverty, economic instability, and civil unrest related to the Civil Rights movement. Adoption of value-based care delivery practices to improve clinical and financial performances among FQHCs has been slow. This slow adoption has been attributable to cost, lack of expertise, and support. Since August 1994, the Department of Health Resources and Services Administration (HRSA), the funding source for …
Midpalatal Suture Maturation Stage Evaluation In Young Adults, Anna Maria Betlej
Midpalatal Suture Maturation Stage Evaluation In Young Adults, Anna Maria Betlej
All ETDs from UAB
Rapid palatal expansion (RPE) is a gold standard treatment for posterior unilateral and bilateral crossbites or limited buccal overjet in patients with constricted maxilla. Midpalatal suture fusion is a limitation for obtaining the skeletal results and avoiding dental side effects. It is generally believed that midpalatal suture interlock increases significantly after the pubertal growth spurt. However, in the literature there are reported cases of successful midpalatal suture split in older adults. Individual cone-beam computed tomography (CBCT) assessment of midpalatal suture maturation was proposed by Angelieri et al. Since RPE treatment approach is commonly used it is important to understand the …
Facilitating The Transfer Of Cognitive Training To Real-World Functioning: The Transfer Package For Post-Stroke Cognitive Impairment, Jason Alexander Blake
Facilitating The Transfer Of Cognitive Training To Real-World Functioning: The Transfer Package For Post-Stroke Cognitive Impairment, Jason Alexander Blake
All ETDs from UAB
Multiple cognitive training approaches for cognitive impairment following acquired brain injury have been found to improve cognitive functioning in the laboratory setting. However, current studies suffer from a lack of focus on the transfer of improved cognitive functioning from the laboratory setting to a patient’s everyday life. This case series addresses this lack of treatment transfer using a collection of behavioral techniques known as the Transfer Package. The Transfer Package works alongside clinical and in-laboratory training of functional cognitive impairments to improve an individual’s real-world functioning and independence after injury. This cognitive training case series utilizes this Transfer Package in …
Beliefs And Intentions Of Anesthesia Physicians Toward Providing Culturally Competent Care To Transgender Patients, Erin Elizabeth Blanchard
Beliefs And Intentions Of Anesthesia Physicians Toward Providing Culturally Competent Care To Transgender Patients, Erin Elizabeth Blanchard
All ETDs from UAB
Purpose: Transgender patients face healthcare discrimination, resulting in a delay or avoidance in seeking care and increased negative health outcomes. The presence of cultural competence in patient-provider interactions has been shown to increase trust and satisfaction, resulting in better health outcomes. However, physicians receive little to no training on how to interact with transgender patients in a culturally competent manner. Anesthesia physicians often have no prior relationship with their patients and have very limited time for patient interaction before delivering care. This is why it is essential that anesthesia physicians possess the knowledge and skills to treat all types of …

Methods: Fifteen children with at least one cavitated carious tooth and one healthy tooth were enrolled and following examination, a carious tooth was selected to receive SDF treatment. Prior to SDF treatment, two supragingival plaque samples were obtained (using sterile cotton swabs, then storage in transport fluid and frozen at -80oC until DNA extraction) at the first appointment, one carious tooth, another from a non-carious tooth. At the …
Social Inclusion Among People With Mobility Limitations In The Global South, Shane Burns
Social Inclusion Among People With Mobility Limitations In The Global South, Shane Burns
All ETDs from UAB
An estimated 15% of the world’s population have a disability—roughly 80% of whom live in the Global South. People with disabilities experience profound social disparities that affect their quality of life and social inclusion. Due to the array of cultural perspectives and institutional capacities around the globe, provision of disability rights can come with its challenges. In many cultural contexts, people have moral beliefs about disability that result in shame. More medicalized beliefs toward disability are often the result of medical infrastructure that offers goods and services. Using a framework that arrays these moral and medical dimensions, I theorized that …
The Relationship Between Anosgnosia For Hemiplegia After Stroke And Fall Events In The Acute Inpatient Stroke Rehabilitation Population, Elizabeth Mosley Byrd
The Relationship Between Anosgnosia For Hemiplegia After Stroke And Fall Events In The Acute Inpatient Stroke Rehabilitation Population, Elizabeth Mosley Byrd
All ETDs from UAB
Background/Significance: Inpatient falls on acute stroke rehabilitation units remains a significant issue that negatively affects healthcare costs and causes physical and psychological injury. Prevelance of falls in the stroke rehabilitation population may be due to the presence of anosognosia for hemiplegia (AHP), which is as an unawareness of physical disability. Though the link between AHP and falls has been suggested in the literature, a formal investigation has not been conducted to address the relationship between the variables. Purpose: To explore the association between the presence of anosognosia for hemiplegia after stroke and patient fall events while admitted to an acute …

All ETDs from UAB
The opioid epidemic began in the early 1990s due to the misuse and misinformation of pharmaceutical opioids. Since then, the increase in opioid use ranging from hydrocodone to fentanyl has become a world-wide issue. Over time, opioid use has evolved in many ways with three major waves of opioid use beginning with oxycodone, moving to heroin, and finally to fentanyl. Usage of online platforms and forums to sell and buy illicit opioids has increased significantly due to easier internet capabilities and social media platforms. A total of 1,946 illicit online opioid sell sites were found in this study to show …

Likelihood Based Inferential Methods To Analyze Trials Incorporating Patient's Treatment Choice, Rouba A. Chahine
All ETDs from UAB
Randomized clinical trials (RCT) are the gold standards for clinical trials as they reduce bias and minimize variability between different arms of a study. One of the drawbacks of these designs is their lack of flexibility to incorporate patient’s preference, which may reduce recruitment rates and/or reduce patient’s tolerance if they receive a non-preferred treatment. Designs incorporating choice allow a subset of participants to choose a preferred treatment. Some of these designs are Zelen’s (1979), Brewin’s (1989), and Rucker’s (Two-Stage RCT, 1989). Current methods to analyze two-stage RCT are based on an analysis of variance (ANOVA) approach that do not …

Do Outcomes From A Behavioral Weight Loss Intervention Differ In Alabama Vs Colorado?, Julianne Clina
All ETDs from UAB
There are well-established regional differences in obesity prevalence in the U.S., but relatively little is known about whether these differences impact efforts for weight loss. The objective of the study was to determine whether changes in body weight, engagement in physical activity (PA), and psychosocial factors differed in Colorado (CO) vs Alabama (AL) in response to a 16 week standardized behavioral weight management program. We hypothesized that weight loss would be greater in Colorado due to a more favorable physical and social environment.This is an ancillary study to a weight loss intervention being conducted simultaneously in AL and CO with …
Central Vestibular Integration In Concussion And Multiple Sclerosis, Graham Dean Cochrane
Central Vestibular Integration In Concussion And Multiple Sclerosis, Graham Dean Cochrane
All ETDs from UAB
Dizziness and imbalance are commonly reported by people with concussion and people with multiple sclerosis (MS). Dysfunction of the vestibular system is likely a major cause of dizziness and imbalance in both diseases, but it is not well understood whether this dysfunction typically occurs in peripheral vestibular organs and pathways or higher-level central vestibular integration pathways. As these systems are assessed and targeted with rehabilitation differently, understanding how both are affected in these diseases will improve management of dizziness and imbalance. In addition, balance has been demonstrated to correlate with self-reported fatigue in people with MS, presumably through shared dysfunction …

Hyperphosphatemia Contributes To Functional Iron Deficiency And Skeletal Muscle Wasting, Brian Anthony Czaya
All ETDs from UAB
Chronic kidney disease (CKD) is a global health threat that increases risk of death, which is credible to both impaired renal function and a multitude of CKD- associated comorbidities such as systemic inflammation, anemia and skeletal muscle dys- function. A distinctive feature of CKD is the dysregulation of mineral metabolism, where excess serum levels of phosphate (hyperphosphatemia) and of fibroblast growth factor 23 (FGF23) are not only viewed as biomarkers for disease severity but also exert deleterious effects towards various CKD-associated pathologies. Elevated levels of FGF23 can lead to the activation of FGF receptor 4 (FGFR4) in cell types that …
Examining The Pathophysiology Through Which Violence Exposure Varies With Functional Brain Connectivity And The Psychophysiological Response To Stress, Heather Elizabeth Dark
Examining The Pathophysiology Through Which Violence Exposure Varies With Functional Brain Connectivity And The Psychophysiological Response To Stress, Heather Elizabeth Dark
All ETDs from UAB
Violence exposure during childhood and adolescence is associated with susceptibility to internalizing disorders such as depression and anxiety. The relationship between childhood violence exposure and internalizing disorders may be explained by changes in brain function. For example, childhood maltreatment, including violence exposure, is associated with changes in brain regions that are important for emotion regulation. Reciprocal connections among these brain regions are important for healthy responses to stress. Thus, examining how childhood violence exposure varies with acute stress-induced changes in functional brain connectivity and psychophysiological stress responses may elucidate how childhood violence exposure may contribute to susceptibility to internalizing disorders. …

Targeting Oncogenic Microrna In Lung Cancer, Mackenzie Lauren Davenport
All ETDs from UAB
Lung cancer is the leading cause of cancer-related death both in the United Statesand the world. While several genetic drivers of lung cancer have been identified, major improvements in patient outcome are lacking, highlighting the need to further understand the genetic and molecular mechanisms of this disease. The microRNA miR-31 has been implicated in oncogenesis in a variety of cancer types, and prior data from our laboratory has shown it to be overexpressed in human lung adenocarcinoma tumors compared to normal lung, high miR-31 levels correlate with decreased patient survival, and overexpression of miR-31 alone in the mouse lung epithelium …
Use-Dependent, Post-Critical Period Structural Plasticity In Primary Visual Cortex Following Central Vision Loss, Matthew Defenderfer
Use-Dependent, Post-Critical Period Structural Plasticity In Primary Visual Cortex Following Central Vision Loss, Matthew Defenderfer
All ETDs from UAB
To facilitate learning throughout life, the adult brain must be capable of change, known as neuroplasticity. While evidence for adult structural plasticity in primary visual cortex (V1) exists, the relationship between plasticity and amount of use of a cortical region is not fully understood. Here, I use macular degeneration (MD) to model adult cortical plasticity. Macular degeneration causes loss of central vision, and patients learn to use a portion of peripheral vision called the preferred retinal locus (PRL) as a replacement for the fovea. The PRL is used more often than other usable areas of peripheral vision for daily tasks. …
The Function Of Tgfβr3 (Betaglycan) In The Differentiation And Proliferation Of T Cells, Samuel Duesman
The Function Of Tgfβr3 (Betaglycan) In The Differentiation And Proliferation Of T Cells, Samuel Duesman
All ETDs from UAB
TGFβR3 is a membrane bound co-receptor to many members of the TGFβ superfamily of ligands and is broadly expressed in the human body. TGFβR3 is known to modulate immune system function, but its exact role is at this time poorly understood. Work by Aleman-Muench et al., (2012) suggests that TGFβR3 regulates T cell development in the thymus. In order to further investigate the role of TGFβR3 in the immune system our lab developed a mouse which lacks TGFβR3 selectively in mature T cells. The contribution of TGFβR3 on in vivo activation and differentiation of T cells was investigated by utilizing …

Design, Construction, And Testing Of A Differential Resistance Elliptical Exercise Machine, John Easton
All ETDs from UAB
Hemiplegia and hemiparesis are life-altering conditions that lead to secondary effects including pain and health decline due to sedentary lifestyle. There exists a need for affordable, safe, and effective exercise equipment designed with these users in mind. Recent studies have demonstrated adaptability of post-stroke individuals to differential forces in a split belt treadmill regime, resulting in increased propulsive force generation of the paretic limb. An elliptical exercise machine with a differential resistance mechanism, free-wheeling motor assistance, and walker accessibility has been fabricated to test whether differential resistance is possible with an elliptical platform. Preliminary testing of 1 subject consisted of …
Race, Feeding Practices And Infant Weight Gain During The First 6 Weeks Of Life, Alysha Breanne Everett
Race, Feeding Practices And Infant Weight Gain During The First 6 Weeks Of Life, Alysha Breanne Everett
All ETDs from UAB
Background: Non-Hispanic black (NHB) infants are disproportionately affected by rapid weight gain compared to non-Hispanic white (NHW) infants, which in turn, is associated with future disparities including obesity and cardiometabolic disease. Feeding practices, such as the use of formula or bottles, differ by race and are associated with rate of weight gain. Data from the Pregnancy and Early Life in the South (PEARLS) birth-cohort study was used to test the hypotheses that change in body weight and weight-for-age z-scores (WAZ) from birth to 6 weeks would be greater for (1) NHB versus NHW infants; and (2) infants fed formula (exclusively …

Does Interdisciplinary Care Team Care Management Improve Health Quality And Demonstrate Cost Effectiveness?, F Cardwell Feagin
All ETDs from UAB
The U. S. healthcare system faces unsustainable rising healthcare costs. Health care cost as a percentage of gross domestic product is expected to rise to 19.4 percent by 2027 (Wilson, 2019). This unstainable rise in healthcare costs is creating a problem for consumers of healthcare. By 2030, the average annual healthcare spending per working household, including premium and out-of-pocket expenditures, is estimated to be 33.9 percent of median compensation (Girod et al., 2016). Also, lawmakers and policymakers face funding issues of healthcare. A key finding of this study is that field-based interdisciplinary care team care management, with an algorithm selecting …

Cognitive Progression And Care Patterns In All-Cause Dementia By Prior Cancer Diagnosis, Mackenzie Elisha Fowler
All ETDs from UAB
Cancer and dementia are common aging-related diseases. Cancer and itstreatments are associated with cognitive impairment referred to as cancer-related cognitive impairment (CRCI). Dementias demonstrate similar impairment. Only one study has examined the longitudinal association between cancer and dementia. This dissertation goes beyond limitations of the prior study and has three aims: 1.) to evaluate dementia progression by prior cancer diagnosis, 2.) to evaluate progression of all-cause dementia by cancer treatments, and 3.) to evaluate patterns and predictors of care among dementia patients by cancer history. This study uses EHR data to evaluate cognitive progression by cancer history /cancer treatment characteristics, …
“Her Feeling Had Come Too Late”: Emotion And Time In Virginia Woolf’S Modernism, Madison Frost
“Her Feeling Had Come Too Late”: Emotion And Time In Virginia Woolf’S Modernism, Madison Frost
All ETDs from UAB
Mikhail Bakhtin’s idea of chronotope, or time-space, encompasses the idea that time and space cannot be separated from one another; they are intertwined. This concept of Bahktin’s is seen in Virginia Woolf’s To the Lighthouse, Mrs. Dalloway, and Orlando because of Woolf’s aim to more accurately depict the reality of modern life, something she deems necessary for modern writers in her essay “Modern Fiction.” Woolf makes use of various narrative techniques to experiment with her illustration of everyday life where she focuses heavily on the depiction of time-space through her illustration of consciousness. Woolf is able to add emotion to …
