Sulfated Dehydropolymer Of Caffeic Acid For Repair Of Lung Damage And Emphysema, Tien M. Truong

Theses and Dissertations

The complex pathobiologic mechanisms of emphysema are not fully understood, leaving this deadly disease without effective pharmacotherapy for a cure. This project hypothesized that the sulfated dehydropolymer of caffeic acid (CDSO3) exhibits Fe²⁺ chelation-based hypoxia inducible factor-1a (HIF-1a) up-regulatory protective activities against in vitro emphysematous cell death and for in vivo reversal of emphysema induced with SU5416, a vascular endothelial growth factor blocker.

Using in vitro chromogenic competitive inhibition assays, CDSO3 was shown to chelate Fe²⁺ (IC₅₀ of 23 µM), but not Fe³⁺ ions. The trypan blue exclusion and lactate

dehydrogenase assays were then employed to …

Methcathinone Analogue Activity At The Human Serotonin Transporter, William Drake Varn

Theses and Dissertations

In the last few years, there has been continued concern about synthetic drug abuse in both the United States and worldwide. Small adjustments in drug compound structure often allow synthetic drug makers to manufacture a legal product that can produce the same highs as illegal counterparts. Unfortunately, this is happening faster than the government can outlaw the drug compounds, and a wide variety of synthetics are now appearing on the street. This study evaluated the effects on the human serotonin transporter of six different 4-para substituted methcathinone compounds. Using a Xenopus oocyte model, the efficacy of each MCAT analogue …

Examining Genetic And Environmental Influences On Alcohol Use And Externalizing Behaviors In African American Adolescents, Neeru Goyal

The aim of this thesis is to expand our understanding of the etiology of alcohol misuse and related disorders in African Americans using genetically informative study designs. Specifically, we take advantage of the candidate-gene approach and polygenic score analysis to extend the literature specific to African American populations. Chapter 2 explores gene x environment (GxE) interactions through the candidate gene approach to explore the relationship between two genes chosen on their potential relevance to stress response and adolescent alcohol use and misuse, among African American youth living in highly impoverished neighborhoods, as moderated by stressful life events. Chapter 3 implements …

I Reach Toward The Ground I Reach Toward Space, Kristen A. Sanders

Theses and Dissertations

Imagine one million and six hundred thousand years ago — a prehistoric character points. There in the moistened soil, the hominid Homo habilis draws a line, inscribing with her finger the first mark. At the core of my work is a meditation on this very scene as the otherwise unknowable origins of image making. And at the center of this discovery is a prehistoric woman — a previously invisible character within human evolution. My work aims to insert these characters into the origins of tool use, image making, and other supposed markers of humanness while also examining historical representations of …

Sweaty Mother Slow Groove, Devin Kylie Harclerode

Theses and Dissertations

Sweaty Mother Slow Groove is an engagement in magical thinking that proposes a displacement of swamp methodologies into the virtual realm, existing during the fourth wave. In doing so the cyborg and goddess are united in a re-routing of essentialism and the neo-liberal domination of technology. The metaphorical swamp is the possibility of a mushy danger zone that harnesses the absorption of an unwanted space: a disintegration of the binary and the soft-coded awareness of the body as a process, not a site.

The Exchange: Curating Authenticity + Interaction, Sarah Webb

Theses and Dissertations

For a physical space to have an emotional impact on those who experience it, we must consider the connection and relationship between objects and experience, and how people make individual connections to insentient places. It is this symbiotic relationship that allows a building or space to attain a “soul”.

Through the adaptive re-use of a Richmond, Virginia building, this thesis project explores strategies of staging physical interaction and organic experiences through art and culture in the context of a mixed-use niche hotel.

It's Slapstick Design, Thanks! Wait! No "Thanks"- Just Slapstick Design ..., Curtis A. Bailey

Theses and Dissertations

I'm arguing for an approach to generating graphic form based on slapstick. Slapstick is a genre of physical comedy involving humorous portrayals of clumsiness, mistakes, and nonsense. I investigate it as an approach to form, content, process, and communication. These methods were used to construct an immersive installation loosely based on The Tibetan Book of the Dead.

Graphic design is expected to function. It does this by conditioning users to its particular patterns or by skillfully implementing familiar patterns. A slapstick approach to graphic design is valuable as a critical tool for disrupting conditioned experiences for promoting empathy by relating …

No Woman Is An Island, Adele Ball

Theses and Dissertations

We have gathered the following pages to archive our time here in Richmond, Virginia. We have been here for two years, growing slowly, moving when needed to new anchorholds to avoid detection or arrest. We scrutinize the urban environment like modern archeologists. We collect stories and speculate about new uses of old things. It is imperative to be resourceful here, and we do so out of necessity but also in the spirit of practice. These pages were made en route, each an exploration of the tools at hand when on the move. The method of creation is just as important …

Choreographic Space, Kelsey Sheaffer

Theses and Dissertations

This thesis, Choreographic Space, and accompanying exhibit is an arrangement of contemporary work being done in the cross-over between movement, drawing, sound and architecture. The thesis develops a lineage of choreographic thinking through a fissure in the classification of a dance as necessarily the body in motion. Through the link of the “choreographic object,” Choreographic Space asks how an interdisciplinary exploration of the principles of movement can reveal novel ways to think about the body in space.

Death Vegas Valley, Eric M. Diehl

Theses and Dissertations

My work explores hallucinatory landscapes of the US American West by using a combination of painting styles outside of the Western painting canon. I cross-reference painting and cinema, interweaving video, acrylic paint and the panorama to create a satirical homage to the history and present state of the USA. However, through an earnest devotion to the medium - both painting and cinema - I find my criticisms also yearn to hold onto a belief in a myth I know to be false.

This is an American History conversation about artifice and consumerism through advertising. I use Las Vegas and the …

Truth And Doubt In Representation, Mathew Gasparek

Theses and Dissertations

My work deals with the connection between the act of representation and conceptions of truth in the contemporary image-mediated social environment. This thesis details elements of my paintings in exchange with methods and ideas from artists and writers in order to position my aesthetic and conceptual sensibilities within a historical and contemporary framework.

Novel Small Airway Model Using Electrospun Decellularized Lung Extracellular Matrix, Bethany M. Young

Theses and Dissertations

Chronic respiratory diseases affects many people worldwide with little known about the mechanisms diving the pathology, making it difficult to find a cure. Improving the understanding of smooth muscle and extracellular matrix (ECM) interaction is key to developing a remedy to this leading cause of death. With currently no relevant or controllable in vivo or in vitro model to investigate diseased and normal interactions of small airway components, the development of a physiologically relevant in vitro model with comparable cell attachment, signaling, and organization is necessary to develop new treatments for airway disease. The goal of this study is to …

Antithetical Commentaries On X, Y And The Disruption Of Being, Eva Rocha

Theses and Dissertations

Through discursive essays and poetic narrative, Antithetical Commentaries on X, Y and the Disruption of Being explores the tenuous relationship between modes of measurement and the struggle for human relevance in the post-contemporary digital age. In the introductory essay, “Not the Feather, but the Bird”, I give an overview of the inherent problems of object-oriented ontology, and how it relates to aesthetics and social issues of our times. In the Developmental Overview, I detail how I developed my installation approach and techniques, particularly with regard to the three-way dynamic of the artist:work:viewer relationship and how it can encourage …

Sensible Nonsense, Timothy J. Woodbrey

Theses and Dissertations

“Truth happens only by establishing itself in the strife and the free space opened up by truth itself. Because truth is the opposition of clearing and concealing, there belongs to it what is here called establishing.”[i]—Martin Heidegger

All things contain their own individual existence. When I look at objects I notice material, tradition, individual history. These are starting points for my imagination to seed and germinate. My ideas are fragmented, nonlinear and nonsensical to others but they hold honesty to me. Honesty is powerful and is worth sharing.

This document is an examination of my work during …

Quantitative Analysis Of 5-Chloro-2-Methoxy-N-[2-(4-Sulfamoylphenyl)Ethyl]Benzamide (Glyburide Analogue, Ga) In Mouse Plasma And Whole Blood Using A Micro-Extraction And Liquid Chromatography-Tandem Mass Spectrometry, Ankit Zalavadia

Theses and Dissertations

Pharmacokinetic evaluation of 5-chloro-2-methoxy-N-[2-(4- sulfamoylphenyl)ethyl]benzamide in mouse plasma demanded for a suitable bioanalytical method. No reported bioanalytical method exists to-date that can quantify concentration of this compound in any biological matrix. The purpose of this study was 1) to develop and validate a new bioanalytical method using a micro-extraction and LC-MS/MS to quantify the target analyte in mouse plasma and 2) to partially validate the method in whole blood. A bioanalytical method was developed and validated in both matrices for a linear concentration range of 2-1000 ng/ml. For both matrices, the reverse predicted concentration of calibration standards (-8.95% to 12.16% …

Conditional Cardiac-Specific Akap13 Knockout Induces Sex Dependent Biventricular Dilated Cardiomyopathy With Sarcomeric And Mitochondrial Defects, Kimberlyn M. Baig-Ward

Theses and Dissertations

Heart disease is a complex and heterogeneous disease. Notably, studies have demonstrated gender differences in the expression and types of cardiovascular disease, such as dilated cardiomyopathy (DCM), a major underlying cause of heart failure. Previously we showed that loss of A-Kinase Anchoring Protein 13 (Akap13), a unique proto-oncogene and estrogen receptor modulator, resulted in enlarged embryonic hearts, defective cardiac sarcomere formation, and embryonic lethality in mice. Data have also shown cAMP-dependent Protein Kinase A (PKA) to be involved in DCM pathophysiology. Given the established role of AKAP13 in cell signaling, its ability to bind and modulate ligand-activated nuclear hormone …

Exploring The Outcomes Of Rehabilitative Care For Veterans And Service Members Treated For A Disorder Of Consciousness In The Vha Emerging Conciousness Program, Janette A. Hamilton

Theses and Dissertations

Over the past several years, there has been an influx in patients being treated for polytraumatic injuries within the Veterans Health Administration (VHA), largely due to the wars in Afghanistan and Iraq, but also due to advances in life sustaining medical interventions. The polytrauma population includes veterans who have sustained a severe traumatic or non-traumatic brain injury, and a significant loss in cognitive and physical functioning, referred to as a disorder of consciousness. The purpose of the current study was to explore factors related to successful emergence from a disorder of consciousness, using a sample of veterans who were treated …

Theses and Dissertations

In my work, I present the moments of true emotional clarity and impactful memories from my life. I strive to provide insight into my experiences and my understanding of others’ motivations. The creative process helps safely guide me through memories of the past and understanding of others.

In my abstracted mixed media paintings and crafts, I use bold jewel tones to express strong feelings and passionate emotions. I also incorporate found objects and paints to communicate the layers and varied depth of memories. With the use of these varied materials, I have developed a personal symbolic language that allows me …

Human Neural Progenitor Cells Are Productively Infected By R5-Tropic Hiv-1: Opiate Interactions On Infection And Function Involve Cdk5 Signaling, Joyce Magat Balinang

Theses and Dissertations

Human immunodeficiency virus type 1 (HIV-1) is known to cause a spectrum of neurological, behavioral and motor deficits collectively termed as HIV-1 associated neurocognitive impairments (HAND). Opiates augment HIV-related CNS complications through both direct and indirect mechanisms that disrupt glial and neuronal function. All CNS macroglia and neurons derive from neural progenitor cells (NPCs) during development, and NPCs in the adult brain contribute to repair processes. Since disruptions in NPC function are known to impact CNS populations and brain function in a number of disease/injury conditions, we determined whether HIV ± opiate exposure affected the maturation and fate of human …

Curcumin/Melatonin Hybrids As Neuroprotective Agents For Alzheimer's Disease, John Saathoff

Theses and Dissertations

Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the leading cause of dementia, affecting ~5.2 million Americans. Current FDA approved medications provide mainly symptomatic relief and there are no agents available to delay or cure this disease. Multiple factors such as amyloid-β aggregates, dyshomeostasis of biometals, oxidative stress, and neuroinflammation have been implicated in the development of AD. Even though significant advances have been made in understanding the mechanisms leading to AD, the exact etiology still remains elusive. Given AD’s multifactorial nature, a multifunctional strategy of small molecule design would help to identify novel chemical templates. Recently our lab …

“‘It’S A Cu’Ous Thing Ter Me, Suh’: The Distinctive Narrative Innovation Of Literary Dialect In Late-Nineteenth Century American Literature”, Kym M. Goering

Theses and Dissertations

American literature and verse advanced in dialectal writing during the late-nineteenth century. Charles Chesnutt’s “The Goophered Grapevine” (1887), “Po’ Sandy” (1888), and “Hot-Foot Hannibal” (1899); Joel Chandler Harris’ Uncle Remus: His Songs and His Sayings (1881); Thomas Nelson Page’s “Marse Chan” (1884); and Mark Twain’s “Sociable Jimmy” (1874) and “A True Story, Repeated Word for Word as I Heard It” (1874) provided diverse dialect representations. Dialect expanded into poetry with

James Whitcomb Riley’s “She ‘Displains’ It” (1888), “When the Frost is on the Punkin” (1882), and “My Philosofy” (1882) and Paul Laurence Dunbar’s “The Spellin’ Bee” (1895), “An Ante-Bellum Sermon” …

The Implementation And Emulation Of Cult Movie Marketing, Rebekah W. Mckendry

Theses and Dissertations

Cult media is often an area of media studies that is difficult to define. Cult media branches through numerous time periods, genres, and fandom patterns. Cult trends are also constantly evolving over time, changing from word-of-mouth and point-of-sale advertising to social networks and Internet culture. But have the rudimentary basics of how media cults develop and spread their message changed along with the progressing marketing presentation? This dissertation explores the definition of media cults, their history, and marketing styles over time, ultimately exploring the tools utilized to market cult media and examine how these tools are now synthetically applied to …

Exploring The Concept Of Human Oct3 Inhibitors As A Novel Class Of Antidepressants, Kavita A. Iyer

Theses and Dissertations

The Dukat laboratory developed 2-amino-6-chloro-3,4-dihydroquinazoline (A6CDQ) as a 5-HT₃ receptor ligand. A6CDQ and one of its positional isomers, the 7-chloro analog A7CDQ, produced antidepressant-like effects in the mouse tail suspension test (TST). We investigated and systematically ruled out a solely 5-HT₃ receptor or hSERT mediated mechanism of antidepressant-like effect for both A6CDQ and A7CDQ.

The role of organic cation transporter 3 (OCT3) as an alternative mechanism in the regulation of neurotransmitters including serotonin (5-HT) and the therapeutic potential of targeting hOCT3 to achieve antidepressant effects has been established. By virtue of possessing protonatable nitrogen atoms, 2-aminodihyroquinazolines could potentially …

Role Of Vav2 In Podocyte Inflammasome Activation And Glomerular Injury During Hyperhomocysteinemia, Sabena Conley

Theses and Dissertations

Hyperhomocysteinemia (hHcys) is a widely known pathogenic factor in the progression of end-stage renal disease (ESRD) and it is also associated with an increased risk for injurious cardiovascular pathologies during ESRD. HHcys is linked to the formation and activation of the NOD-like receptor protein 3 (NLRP3) inflammasome, characterized as a critical early mechanism initiating the inflammatory response. NADPH oxidase (NOX)-derived reactive oxygen species (ROS) mediate the activation of the NLRP3 inflammasome in podocytes in response to elevated levels of homocysteine (Hcys) in vitro and in vivo. However, it remains unknown how NLRP3 inflammasome activation is triggered by NOX. The …

Eeg Interictal Spike Detection Using Artificial Neural Networks, Howard J. Carey Iii

Theses and Dissertations

Epilepsy is a neurological disease causing seizures in its victims and affects approximately 50 million people worldwide. Successful treatment is dependent upon correct identification of the origin of the seizures within the brain. To achieve this, electroencephalograms (EEGs) are used to measure a patient’s brainwaves. This EEG data must be manually analyzed to identify interictal spikes that emanate from the afflicted region of the brain. This process can take a neurologist more than a week and a half per patient. This thesis presents a method to extract and process the interictal spikes in a patient, and use them to reduce …

The Role Of Matrix Metalloproteinase 9 And Osteopontin In Synaptogenesis And Reinnervation Of The Olfactory Bulb Following Brain Injury, Melissa A. Powell

Theses and Dissertations

Traumatic brain injury (TBI) is a serious health concern, causing cognitive, motor, and sensory deficits, including olfactory dysfunction. This dissertation explores the effects of TBI on synaptic plasticity within the olfactory system, seeking to define mechanisms guiding postinjury sensory reinnervation. Physical forces induced by TBI can axotomize olfactory receptor neurons (ORNs), which innervate olfactory bulb (OB). These axons regenerate OB projections after injury, a process involving growth through a complex extracellular matrix (ECM). As such, we investigated a potential molecular mechanism capable of modifying local OB ECM to support postinjury synaptogenesis. Since matrix metalloproteinases (MMPs) and their ECM substrates are …

The Role Of Enteric Glia In Opioid-Induced Constipation, Sukhada Bhave

Theses and Dissertations

Morphine is one of the most widely used drugs for the treatment of pain but its clinical efficacy is limited by adverse effects including persistent constipation and colonic inflammation. Morphine-induced colonic inflammation is facilitated by microbial dysbiosis and bacterial translocation. In this study, we demonstrate that secondary inflammation and persistent constipation are modulated by enteric glia. In chronic morphine treated mice (75 mg morphine pellet/5 days), ATP-induced currents were significantly enhanced in enteric glia isolated from the mouse colon myenteric plexus. Chronic morphine resulted in significant disruption of the colonic epithelium and increased Il-1β in the myenteric plexus. The increase …

Investigating The Role Of The Nucleosome Remodeling Factor Ino80 In Development And Nurf In Anti-Tumor Immunity, Zeinab Abdallah Elsayed Ms

Theses and Dissertations

Understanding how an epigenetic regulator such as ATP-dependent chromatin-remodeling complexes modulate processes such as development and/or immune response is essential for our comprehension of cell biology. Deletion of the ATP-dependent chromatin remodeling factor INO80 is known to be embryonically lethal, however, the mechanism is not known. To identify roles for INO80 in mouse early development we generated Ino80 KO mice. Ino80 KO ESCs (Embryonic stem cells) were viable when maintained at ground state pluripotency but fail to differentiate in vitro and in vivo. Gene expression analysis of Ino80 KO early embryos by in situ hybridization showed elevated Bmp4 expression …
