Sculpture + Extended Media

My MFA thesis project is a ten-minute video installation entitled Emporium, in which I adorn, strap, tie, hang, and wrap the bodies of performers with my sculptures, and then let loose these hybridized bodies in the non-linear dream-time of cinema. Riffing on the fantastical taxonomy of Jorge Luis Borges’s The Celestial Emporium of Benevolent Knowledge, I …

The Moon Cuts Like Pye, But Not Cherry, Jacqueline Avery Collins

Theses and Dissertations

In our work we prefer asking questions to telling stories.

As a means to invigorate and cross-examine our current reality, our hystories, and our definitions of ‘self’ we peer through a disparate lens cultivating pockets: compartments longing to be filled, gaping holes between maybes, masked, and bound to their binding. We relate these pockets anatomically to that of the 
sublingual space or potential space. It is here, at the tip of digestion, where transmogrification ensues. This evolution manifests as a series of states of possible beings and territories through live scenario. Traversing the possibilities of potentiality: the intermediary that rejects …

Taf2: A Potential Oncogene For Hepatocellular Carcinoma, Saranya Chidambaranathan Reghupaty

Theses and Dissertations

Astrocyte Elevated Gene 1 (AEG1) is an oncogene for hepatocellular carcinoma (HCC). Its role in HCC pathogenesis has been well studied. A pan cancer analysis of gene expression in multiple databases identified TATA-box binding protein associated factor 2 (TAF2) as the gene that is most frequently co-expressed with AEG1. TAF2 is a protein that is involved in transcription of genes by RNA polymerase II. It is a factor that is dispensable for basal transcription but, required for activated transcription. It has also been shown to be involved in regulating cyclin levels and hence cell cycle progression. Bioinformatic analysis on data …

A Systems Biology Approach For Predicting Essential Genes And Deciphering Their Dynamics Under Stress In Streptococcus Sanguinis, Fadi El-Rami

Theses and Dissertations

Infectious diseases are the top leading cause of death worldwide. Identifying essential genes, genes indispensable for survival, has been proven indispensable in defining new therapeutic targets against pathogens, major elements of the minimal set genome to be harnessed in synthetic biology, and determinants of evolutionary relationships of phylogenetically distant species. Thus, essentiality studies promise valuable revenues that can decipher much of biological complexities.

Taking advantage of the available microbial sequences and the essentiality studies conducted in various microbial models, we proposed a framework for the prediction of essential genes based on our experimentally verified knowledge of the pathways involved in …

Structural And Functional Alterations In Neocortical Circuits After Mild Traumatic Brain Injury, Michal Vascak

Theses and Dissertations

National concern over traumatic brain injury (TBI) is growing rapidly. Recent focus is on mild TBI (mTBI), which is the most prevalent injury level in both civilian and military demographics. A preeminent sequelae of mTBI is cognitive network disruption. Advanced neuroimaging of mTBI victims supports this premise, revealing alterations in activation and structure-function of excitatory and inhibitory neuronal systems, which are essential for network processing. However, clinical neuroimaging cannot resolve the cellular and molecular substrates underlying such changes. Therefore, to understand the full scope of mTBI-induced alterations it is necessary to study cortical networks on the microscopic level, where neurons …

Health Aid In Africa: Placement, Service Utilization, And Benefit, Carrie Dolan

Theses and Dissertations

While the health sector has attracted significant foreign aid, evidence on the effectiveness of this support is mixed. This dissertation examines the allocation of health aid within the context of placement, service utilization, and benefit. The first paper examined the sub-national allocation of Chinese development aid projects across Africa. I determined how political preferencing of Chinese aid specifically, allocating aid to the birth region of the current political leader differs across sectors such as health, education, and transportation. I find some evidence that aid, more broadly defined, is subject to political preferencing in recipient countries, which could potentially limit its …

Characterization Of The Role Of Insulin-Like Growth Factor Binding Protein 7 (Igfbp7) Using A Genetic Knockout Mouse Model, Maaged A. Akiel

Theses and Dissertations

In the US, the incidence and mortality rates of hepatocellular carcinoma (HCC) are alarmingly increasing since no effective therapy is available for the advanced disease. Activation of IGF signaling is a major oncogenic event in diverse cancers, including HCC. Insulin-like growth factor binding protein-7 (IGFBP7) inhibits IGF signaling by binding to IGF-1 receptor (IGF-1R) and functions as a potential tumor suppressor for hepatocellular carcinoma (HCC). IGFBP7 abrogates tumors by inducing cancer-specific senescence and apoptosis and inhibiting angiogenesis. We now document that Igfbp7 knockout (Igfbp7-/- ) mouse shows constitutive activation of IGF signaling, presents with pro-inflammatory and immunosuppressive microenvironment, and develops …

Relb Acts As A Molecular Switch To Drive Chronic Inflammation In Glioblastoma Multiforme (Gbm)., Michael R. Waters

Theses and Dissertations

Inflammation is a homeostatic response to tissue injury or infection, which is normally short- lived and quickly resolves to limit tissue damage. In contrast, chronic inflammation has been linked to a variety of human diseases, including cancers such as glioblastoma multiforme (GBM). GBMs are very aggressive tumors with very low patient survival rates, which have not improved in several decades. GBM tumors are characterized by necrosis and profound inflammation; with cytokines secreted by both GBM cells and the tumor microenvironment. The mechanisms by which chronic inflammation develops and persists in GBM regardless of multiple anti-inflammatory feedback loops remain elusive. This …

Expression Of Matrix Metalloproteinases In Naegleria Fowleri And Their Role In Degradation Of The Extracellular Matrix, Charlton Lam

Theses and Dissertations

Naegleria fowleri is a free-living amoeba found in freshwater lakes and ponds that is the causative agent of Primary Amoebic Meningoencephalitis (PAM). Matrix metalloproteinases (MMPs) have been described in protozoa, such as Plasmodium falciparum, Trypanosoma brucei, and Balamuthia mandrillaris, and have been linked to their increased motility and invasive capability by degrading components of the extracellular matrix (ECM). In addition, MMPs are often upregulated in tumorigenic cells and have been attributed as responsible for the metastasis of certain cancers. In the present study, in vitro experiments indicated that MMPs are linked functionally to the ECM degradation process. …

The Anatomy Of Cbpr: A Case Study Of Cbpr Implementation For Health Promotion With The Peer Community, Cory R. Cummings

Theses and Dissertations

This case study is a qualitative examination of a health promotion project conducted in collaboration with members of the mental health peer community. More specifically, it explores the community based participatory research (CBPR) implementation process used to conduct this health promotion project to gain a deeper understanding of the mechanisms at work in the implementation process. While there has been considerable attention to the principles that guide CBPR (Braun et al., 2012; Israel et al., 2008; LaVeaux & Christopher, 2009), there remains important work to be done in bridging these principles to implementation; what processes or mechanisms translate these principles …

The Role Of Human Msc Derived Exosomes In The Treatment Of Periodontal Diseases, Sonia S. Talegaonkar

Theses and Dissertations

Periodontal disease affects 47% of Americans over 30. Characterized by microbial dysbiosis and unregulated inflammation, severe periodontitis causes degradation of bone and soft tissue around teeth. Current treatments have limited regenerative outcomes and frequent reinfection by harmful bacteria. Human mesenchymal stem cells (hMSCs) have been shown to promote wound healing and tissue regeneration. Many therapeutic benefits of hMSCs are due to their secretome products, like exosomes. Our long-term goal is to develop periodontal therapies with hMSC exosomes. The objectives of this study were to determine the effect of hMSC-derived exosomes on cellular activity of hMSCs and investigate whether hMSC exosome …

Advocate Or Traditional Bureaucrat: Understanding The Role Of Esl Supervisors In Shaping Local Education Policy Toward Immigrant Communities, Grant E. Rissler

Theses and Dissertations

As recent immigrants seek a productive and dignified life in “new immigrant destinations” that have little historical experience with immigration, public education systems serve a key function in immigrant integration efforts. In a federal system increasingly focused on accountability, a crucial sub-set of education policy and local responsiveness to immigration is English language instruction and services for Limited English Proficient (LEP) students and parents.

In such contexts, the role that local bureaucrats play, and whether they actively represent the interests of the newfound diversity of community members, are crucial questions if strongly held American ideals of social equity and equal …

A Biorelevant In Vitro Model To Characterize In Vivo Release Of Bone Morphogenetic Protein-2 (Rhbmp-2), Deblina Biswas

Theses and Dissertations

Biorelevant in vitro release/dissolution tests are designed to predict the in vivo behavior of a drug and are crucial in understanding its in vivo performance. Currently, there is no standardized compendial in vitro release testing methods or regulatory guidance’s for release/dissolution testing of implants due to their complex physiological locations.Furthermore, existing compendial methods do not capture the local release profile of ‘novel’ parenterals in physiological low fluid volume surrounding areas.

Long acting and in situ forming implants with orthobiologic proteins and peptides have increased over the past few decades due to a better understanding of genetic engineering. One of these …

N-Alkyl 4-Methylamphetamine Enantiomers And The Implication For Potential Modulation Of Abuse Liability And Enhancement Of Psychoactive Drug Targeting., Ramsey Sitta

Theses and Dissertations

Drugs of abuse have a long history in humanity. Currently however, a subject of great interest is the phenylalkylamine family of drugs. Not only is the abuse liability of interest but also the potential therapeutic expansion of the capabilities of this family of drugs by utilizing the unique stereospecific effects of the newly discovered hybrid compounds. Based upon prior data of N-Alkyl 4-MA the enantiomers of N-Methyl, N-Ethyl, and N-Propyl were analyzed in hDAT, hNET, and hSERT. It was found that there was a negative correlation between chain length and potency and dopaminergic component. In agreement with the currently established …

Reversal Of The Npc Phenotype By Start Domain Proteins, Tavis H. Sparrer

Theses and Dissertations

Niemann Pick Type C (NPC) disease is a fatal childhood neurological disease caused by mutations in the NPC-1 protein, resulting in cholesterol buildup in the late endosomes. StarD4 and StarD5 are cholesterol binding proteins that play a role in the intracellular cholesterol transport. In this study we overexpress StarD4 and StarD5 in in vitro and in vivo models, and find evidence of amelioration of the NPC phenotype. This study demonstrates that the overexpression of these proteins has the potential to be a therapeutic treatment for NPC disease.

Designing Effective Messages To Promote Future Zika Vaccine Uptake, Jeanine Guidry

Theses and Dissertations

The Zika virus is associated with the devastating birth defect microcephaly, and while a vaccine was not yet available in early-2017, several were under development. It is imperative to identify effective communication strategies to promote uptake of a new vaccine, particularly among women of reproductive age. Moreover, though the Zika outbreak has received much social media attention, little is known about these conversations on Instagram. The purpose of this dissertation, therefore, was to understand current Zika-focused communication on Instagram and to inform effective communication strategies to promote future Zika vaccine uptake intent.

The study aims were: (1) explore Zika conversations …

Role Of Translation Initiation In Regulation Of Epithelial Junctions And Cell Motility, Fahda Fawaz Alsharief

Theses and Dissertations

The integrity and barrier properties of intestinal epithelium are determined by specialized adhesive structures known as intercellular junctions; composed of adherens junctions (AJs), tight junctions (TJs) and focal adhesions that mediate cell-cell and cell matrix interactions, respectively. These two types of epithelial cell adhesions regulate each other during disruption and restitution of the epithelial barrier. Inflammatory cytokines such as interferon gamma (IFNγ) and tumor necrosis factor alpha (TNFα) are elevated during intestinal inflammation. The most notable effects of IFNγ and TNFα on intestinal epithelial homeostasis involve disruption of apical junctions and attenuation of cell migration. Although molecular mechanisms underlying these …

The Tea Party Versus Planning: A Study Of Tea Party Activism And Its Impact On Local Government Planning, Spencer A. Norman

Theses and Dissertations

The Tea Party movement’s effect on local and regional planning in Virginia has received little study. This work identifies how conservative political activism has impacted planning in the Commonwealth and how planners have responded. The study relies on a qualitative approach involving 22 semi-structured interviews with activists, planners, and citizens, as well as textual analyses of planning documents, local and regional news reports, and Tea Party social media. The resultant findings show that Tea Party activism is rooted in deep seated ideals about private property rights and individualism. It also reveals that planning processes that increased the amount of public …
