Exploring The Roles Of Long Non-Coding Rnas In Glioblastoma Tumor Recurrence And Therapy Resistance, Christian Tyler Stackhouse Jan 2020

Exploring The Roles Of Long Non-Coding Rnas In Glioblastoma Tumor Recurrence And Therapy Resistance, Christian Tyler Stackhouse

All ETDs from UAB

ABSTRACT Glioblastoma (GBM) is the most common and devastating primary CNS brain tumor with a median survival time of around 14 months. Most patients succumb to re-current disease which is often more malignant than the primary tumor and is frequently therapy resistant. There have not been significant advances in the treatment of GBM despite decades of research. This is partly due to the lack of accurate preclinical models and of the focus on primary rather than recurrent tumors. We created a 350 gene custom GBM-specific panel which contains 16 molecular signatures including molecular sub-typing signatures. We have demonstrated concordance of …

Functionalized Aromatic Organic Scintillators As Tools For Non-Invasive Optogenetics, David French Jan 2020

Functionalized Aromatic Organic Scintillators As Tools For Non-Invasive Optogenetics, David French

All ETDs from UAB

Optogenetics is a growing discipline of neuroscience that attempts to control brain circuits using light. Current techniques involving surgically implanted light-emittingdiodes are highly invasive. This limitation could be avoided by the use of a tissuepenetrative light source, such as x-rays, and a locally applied down-converting material. This work describes the design, optimization, and proof-of-concept application of organic aromatic-based scintillators as non-invasive tools for optogenetics. The first chapter describes the synthesis of 2-anthryl methacrylate-co-methyl methacrylate copolymers and an evaluation of their use as x-ray induced scintillators (radioluminescence). The 2-anthryl methacrylate monomer and the copolymers all exhibited radioluminescence in the solid state. …

The Evolution Of Racism Through The Lens Of Lynching Rhetoric And Memory, Tammy Blue Jan 2020

The Evolution Of Racism Through The Lens Of Lynching Rhetoric And Memory, Tammy Blue

All ETDs from UAB

The Evolution of Racism Through the Lens of Lynching Rhetoric and Memory, examines the use of ‘lynching’ in its definition, legislation and politics. Rhetoric has the power to influence and persuade, therefore when public figures manipulate lynching rhetoric, the meaning of lynching becomes distorted. In part, this thesis explores the difficulty of defining lynching. Among others, key players in this process included Walter White of the National Association for the Advancement of Colored People (NAACP), Monroe Work of the Tuskegee Institute, and Jessie Daniel Ames of the Association of Southern Women for the Prevention of Lynching (ASWPL). Their battle to …

Psychosocial And Physiological Correlates Of Chronic Pain In Persons Living With Hiv, Michael Owens Jan 2020

Psychosocial And Physiological Correlates Of Chronic Pain In Persons Living With Hiv, Michael Owens

All ETDs from UAB

Due to recent advancements in antiretroviral therapy (ART), people living with HIV (PLWH) who respond well and remain adherent to their medication regimens are achieving “near normal” life expectancies. As a result, HIV is no longer considered a death sentence, but rather a chronic health condition to be managed. However, the longer a person lives with the virus, the more prone to HIV-associated chronic diseases he or she becomes. One particularly important health condition with the potential to significantly and negatively impact quality of life is chronic pain. The prevalence rates of chronic pain in PLWH are estimated to be …

Microplastic In Water And Wastewater, Dounia Elkhatib Jan 2020

Microplastic In Water And Wastewater, Dounia Elkhatib

Open Access Dissertations

This thesis addresses three challenges related to the microplastic contamination in water and wastewater treatment plants. The first challenge is the multiple methodologies used to collect, quantify, and characterize microplastics in both wastewater and drinking water. Our study shows a lack of consensus regarding the techniques used at all of the stages (from collection to characterization) required for the quantification of microplastics in urban water systems. This represents a barrier to accurately determine the loads of microplastic contamination and to the comparison of the results obtained among different studies. Our results indicate large discrepancies in the concentrations reported in both …

Control System For Low-Cost Miniature Isopycnal Floats (Minions)' Targeting Distributed Observations Of The Oceanic Biological Carbon Pump, Jackson Sugar Jan 2020

Control System For Low-Cost Miniature Isopycnal Floats (Minions)' Targeting Distributed Observations Of The Oceanic Biological Carbon Pump, Jackson Sugar

Open Access Master's Theses

The flux and attenuation of Particulate Organic Carbon (POC) export through the mid-water column has been a subject of oceanographic research for decades. The methods to sample sinking particles have remained largely unchanged, and interpretation of the data is challenged by uncertainty and sparse measurements. This need prompted our efforts to develop a standalone sensor platform for subsurface timelapse photography of accumulated particles as a proxy for carbon export, combined with simultaneous measurements of dissolved oxygen, temperature and pressure. The use of a flexible Linux single board computer with power cycling enabled the float to be; low power (for long …

O'Kei: An American Novel, Boris Pilnyak, Ronald D. Leblanc (Translator) Jan 2020

O'Kei: An American Novel, Boris Pilnyak, Ronald D. Leblanc (Translator)

Faculty Publications

On January 4, 1931, Boris Pilnyak (1894-1938) wrote a letter to Joseph Stalin, pleading with the Soviet leader to grant him permission to travel to the United States in order to conduct research for an ambitious book project he was undertaking that would compare communist Russia favorably to capitalist America. Pilnyak’s request received official approval, and a few months later the writer set off for the U.S., arriving in New York by steamer on March 12, 1931, and remaining in the country until August 3, 1931. During his nearly five-month stay in America, Pilnyak became acquainted with a number of …

Possibility And Constraint In The Lives Of Young Rural Workers In The Us: The Psychology Of Working And Post-Trauma Vocational Trajectories, Donna M. San Antonio Dr.

Faculty Scholarship

Work and wellness have long been linked in the field of psychology, but few researchers have studied this topic with rural emerging adults without a high school diploma. Overall, rural areas in the United States have higher rates of poverty and lower educational attainment than nonrural areas. This narrative inquiry illuminates how precariousness in home and school contexts influenced the work trajectories and aspirations of ten 20- to 25-year-old research participants. Findings contribute to the psychology of working theory by illuminating the individual and contextual factors that generated possibility and constraint in the lives of young workers with limited education …

Prejudice-Based Rights In Criminal Procedure, Justin Murray Jan 2020

Prejudice-Based Rights In Criminal Procedure, Justin Murray

Articles & Chapters

This Article critically examines a cluster of rules that use the concept of prejudice to restrict the scope of criminal defendants’ procedural rights, forming what I call prejudice-based rights. I focus, in particular, on outcome-centric prejudice- based rights—rights that apply only when failing to apply them might cause prejudice by affecting the outcome of the case. Two of criminal defendants’ most important rights fit this description: the right, originating in Brady v. Maryland, to obtain favorable, “material” evidence within the government’s knowledge, and the right to effective assistance of counsel. Since prejudice (or equivalently, materiality) is an element of these …

Descripción Del Canto De Anuncio Del Sapo Hojarasquero Rhaebo Haematiticus (Cope, 1862) Del Suroccidente Del Chocó Biogeográfico, Diego Batallas, Mario H. Yánez-Muñoz

Neotropical Biodiversity

This note describes the advertisement calls of Rhaebo haematiticus, recorded in Tobar Donoso, province of Carchi‒Ecuador, providing for the first time a quantitative analysis of its spectral and temporal variables. The calls of three populations were analyzed and compared with calls of Rhaebo blombergi and Rhaebo guttatus, two species of the genus Rhaebo present in Ecuador for which acoustic descriptions were available. The results indicate unique interspecific features and intraspecific variations in the advertisement calls, which should suggest the revision of the R. haematiticus as a complex of cryptic species.

Habitat Selection And Diet Of The Neotropical Otter (Lontra Longicaudis) On The Osa Peninsula, Costa Rica, And Range-Wide Monitoring Recommendations, Chris Smith, Andy Whitworth, Elizabeth Brunner, Mateo Pomilia Jan 2020

Habitat Selection And Diet Of The Neotropical Otter (Lontra Longicaudis) On The Osa Peninsula, Costa Rica, And Range-Wide Monitoring Recommendations, Chris Smith, Andy Whitworth, Elizabeth Brunner, Mateo Pomilia

Neotropical Biodiversity

The Neotropical otter (Lontra longicaudis) is listed as Near Threatened by the IUCN, which describes the standardization of field survey techniques and identification of key habitats as two research priorities. Basic ecological information such as habitat selection and diet is also lacking, especially in Central America. Using surveys for tracks and latrines from ten rivers on the Osa Peninsula of Costa Rica, we report results on habitat selection at the local and micro-habitat scales, describe the general diet from 127 scats, and broadly discuss detection and general survey methods. We found that otters were positively associated with small-scale pastures surrounded …

Green Bottle Flies (Calliphoridae, Luciliinae) Of Ecuador: Geographic Distribution, Checklist And Dna Barcodes, Emilia A. Moreno, Eduardo Amat, Pablo E. Meneses, David A. Donoso, Álvaro R. Barragán

Neotropical Biodiversity

Green bottle flies (Diptera, Calliphoridae, Luciliinae) comprise a diverse and cosmopolitan taxon, known from at least 1,500 species. They have become crucial elements in forensic investigations, as they spend part of their life cycle in decaying remains. Here, we review the distribution of eleven Luciliinae species in Ecuador: the monotypic Blepharicnema and ten Lucilia species. We identified specimens using morphological characters. Additionally, we DNA barcoded 43 specimens from three species using 658bp segments of the standard Cytochrome Oxidase I (COI) mitochondrial gen. Molecular and morphological identifications presented high correspondence, suggesting COI barcodes are an efficient tool for the identification of …

No Need For Artificial Light: Nocturnal Activity By A Diurnal Reptile Under Lunar Light, Jeanelle L. K. Brisbane, Matthijs P. Van Den Burg Jan 2020

No Need For Artificial Light: Nocturnal Activity By A Diurnal Reptile Under Lunar Light, Jeanelle L. K. Brisbane, Matthijs P. Van Den Burg

Neotropical Biodiversity

Species are commonly described as either diurnal or nocturnal, with rare reports of deviations outside their normal activity period. Observations of nocturnal activity by diurnal Anolis are limited to lizards utilizing anthropogenic light sources (night-light niche) to prolong their daily activity period. Here, we report nocturnal activity by Anolis cristatellus facilitated solely by natural moonlight and discuss implications for when this behavior would be recognized as common in the future. The identification of nocturnal activity in Anolis is particularly noteworthy given, in contrast to other taxa, our extensive knowledge of this study system which will allow for future ecological studies …

Astrocytic Response To Neural Injury Is Larger During Development Than In Adulthood And Is Not Predicated Upon The Presence Of Microglia, Andrew J. Riquier, Suzanne I. Sollars Jan 2020

Astrocytic Response To Neural Injury Is Larger During Development Than In Adulthood And Is Not Predicated Upon The Presence Of Microglia, Andrew J. Riquier, Suzanne I. Sollars

Psychology Faculty Publications

While contributions of microglia and astrocytes are regularly studied in various injury models, how these contributions differ across development remains less clear. We previously demonstrated developmental differences in microglial profiles across development in an injury model of the gustatory system. Nerves of the rat gustatory system have limited capacity to regenerate if injured during neonatal ages but show robust recovery if the injury occurs in adulthood. Using this developmentally disparate model of regenerative capacity, we quantified microglia and astrocytes in the rostral nucleus of the solitary tract (rNTS) following transection of the gustatory chorda tympani nerve (CTX) of neonatal and …

Words Have A Weight: Language As A Source Of Inner Grounding And Flexibility In Abstract Concepts, Guy Dove, Laura Barca, Luca Tummolini, Anna M. Borghi Jan 2020

Words Have A Weight: Language As A Source Of Inner Grounding And Flexibility In Abstract Concepts, Guy Dove, Laura Barca, Luca Tummolini, Anna M. Borghi

Faculty and Staff Scholarship

The role played by language in our cognitive lives is a topic at the centre of contemporary debates in cognitive (neuro)science. In this paper we illustrate and compare two theories that offer embodied explanations of this role: the WAT (Words As social Tools) and the LENS (Language is an Embodied Neuroenhancement and Scaffold) theories. WAT and LENS differ from other current proposals because they connect the impact of the neurologically realized language system on our cognition to the ways in which language shapes our interaction with the physical and social environment. Examining these theories together, their tenets and supporting evidence, …

Design, Synthesis, And Characterization Of Chemical Tools To Study Peroxisomal Import, Jhalak N. Timilsena

Masters Theses

Peroxisomes are dynamic and interconnected single lipid membrane bound organelles found in the eukaryotic cells which are involved in various biochemical processes including the b-oxidation of very long chain and branched chain fatty acids, metabolism of reactive oxygen and nitrogen species, and reduction of hydrogen peroxide among others. These organelles are known to host numerous proteins and enzymes depending on the cellular environment. All of the proteins needed in the peroxisomes are encoded in the nucleus and synthesized in the cytosol which are then transported to the peroxisomes with the help of a sophisticated protein-transport machinery. Pex5 is one of …

Nest Success In A Grassland Bird Community: Microsite Selection & A Case For Nest Height Manipulation, Matt Kneitel Jan 2020

Nest Success In A Grassland Bird Community: Microsite Selection & A Case For Nest Height Manipulation, Matt Kneitel

Masters Theses

Grassland birds are a sensitive community and populations around the country have been declining. They are susceptible to low nest success due to loss of habitat and the small, fragmented patches that remain are often subjected to elevated levels of nest predation. The American goldfinch (Spinus tristis), which uses grasslands for feeding and nesting, is understudied given its abundance, due in part to its late-season nesting habits, and selection of taller woody vegetation as nesting substrate, which is atypical for many grassland nesting birds. American goldfinches were incorporated in this study which included nest height manipulation of goldfinch …

Representations Of Africa In Us Media: A Semiotic Analysis Of Ebola: The Doctor’S Story And Body Team 12, Olubusola Akinpelu

Masters Theses

The Western media has often been criticized for biased coverage of happenings in and around Africa. The 2014 Ebola outbreak created a lot of media attention for West Africa, and by extension, the entire continent. This study examined to what extent postcolonial discourses were infused in two films from the HBO Trilogy: Ebola: The Doctor’s Story (2015) and Body Team 12 (2015). To analyze these texts, I took a semiotic approach by identifying, describing and interpreting the signs in both films, to discuss the postcolonial discourses in three broad themes. Ebola: The Doctor’s Story (2015) was analyzed in the …

Aging Techniques & Population Dynamics Of Blue Suckers (Cycleptus Elongatus) In The Lower Wabash River, Dakota S. Radford Jan 2020

Aging Techniques & Population Dynamics Of Blue Suckers (Cycleptus Elongatus) In The Lower Wabash River, Dakota S. Radford

Masters Theses

The Blue Sucker, Cycleptus elongatus, occurs in large rivers primarily in the Mississippi River basin. Their imperiled status has called attention to the need for its management and protection. Estimating age is crucial for directing management, but past studies have varied in their choice of hard structure, resulting in uncertainty regarding the basic life history of this species. Because the Wabash River Blue Sucker population may be one of few surveyable populations with high abundance and successful reproduction, their demographics can provide a benchmark against which threatened populations can be compared. We harvested Blue Suckers (n = 168) …

Leadership Development In East Africa: A Case Study Of A Multi-Year College Student Leadership Program, Gregory Armen Muger Jan 2020

Leadership Development In East Africa: A Case Study Of A Multi-Year College Student Leadership Program, Gregory Armen Muger

Theses and Dissertations

Effectual and ethical leadership is a top need throughout all sectors in Sub-Saharan Africa (Adadevoh, 2007; Ncube, 2010). Unfortunately, there is currently very scant literature on Sub-Saharan African leadership theory or programming (Bolden & Kirk, 2009). A large Christian nonprofit organization operated a multi-year servant leadership-based Christian leadership program for thousands of college students throughout sites in East Africa called the Leadership Development Program (LDP). The LDP endeavored to groom local, ethical, and capable leaders. Therefore, studying the LDP model and its impacts could add significant value to Sub-Saharan African leadership practitioners as well as add to the limited body …
