Structural Alterations To The Axon Initial Segment Following Diffuse Axonal Injury As A Consequence Of Age, William Behl
Structural Alterations To The Axon Initial Segment Following Diffuse Axonal Injury As A Consequence Of Age, William Behl
Theses and Dissertations
An epidemiological shift towards the elderly population has occurred in traumatic brain injury (TBI). Age is believed to be one of the strongest prognostic indicators following TBI. Diffuse axonal injury (DAI), a prevalent feature of TBI, is believed to be the primary cause for much of the morbidity and mortality associated with TBI. The pathobiology associated with DAI is believed to occur in response to the primary injury in a progressive, secondary fashion. Though the injury mechanisms behind DAI have been shown to occur at numerous sites along the axon, recent work suggests that the axon initial segment (AIS) may …

Clinical And Radiographic Evaluation Of Mta Pulpotomies: A Retrospective Study, Claudia Colorado
Clinical And Radiographic Evaluation Of Mta Pulpotomies: A Retrospective Study, Claudia Colorado
Theses and Dissertations
Vital pulp therapy is the group of procedures indicated to maintain pulp vitality allowing for continued root development and apical closure in the presence of pulp exposure due to caries or trauma. Complete maturation results in stronger tooth structure that is more able to withstand occlusal forces. Historically, calcium hydroxide (Ca(OH)2) was the material of choice for a vital pulpotomy. Recently mineral trioxide aggregate (MTA) has been used as a pulp sealing material because of its biocompatibility and its ability to induce hard tissue barrier formation. The purpose of this retrospective study was to evaluate the clinical and radiographic outcome …

Glial Cell Modulators And Associated Anti-Inflammatory Activity: Implications In Reducing Methamphetamine Abuse-Related Behaviors In Rodents, Sarah Snider
Theses and Dissertations
Methamphetamine is a psychomotor stimulant that produces hyperactivity and euphoria and can lead to drug-seeking and abuse. An estimate from 2005 put the cost of methamphetamine abuse to society at an estimated 23.4 billion dollars. One of methamphetamine's effects is activation of glial cells and associated neuroinflammatory activity in the periphery and CNS. Glia are responsible for maintaining calcium homeostasis, neuroplasticity, immune activity, and cell signaling. Activation of glia and neuroinflammation are becoming recognized as links in drug abuse-related behavior. The goal of the present work was to assess the ability of ibudilast, AV1013, and minocycline, three glial cell modulating …

An Evaluation Of Prenatal Care Clinic Selection And The Association With Subsequent Process/Outcome Measures Among Medicaid Beneficiaries, Lynn Vanderwielen
An Evaluation Of Prenatal Care Clinic Selection And The Association With Subsequent Process/Outcome Measures Among Medicaid Beneficiaries, Lynn Vanderwielen
Theses and Dissertations
In 2010 Medicaid financed approximately 48% of all births in the United States and nearly 30% of all births in Virginia. Due to strict state-specific eligibility criteria, many low-income women qualify for Medicaid coverage exclusively as a result of pregnancy status. As the nation moves forward with the Patient Protection and Affordable Care Act (PPACA), state-elected Medicaid expansion has the potential to expand services to women of reproductive age that would precede pregnancy events and offer continuous access to care postpartum. Despite this potential influx of newly insured women, little is known about how this population may make decisions regarding …

Characterization Of Putative Porphyromonas Gingivalis Rna-Binding Proteins, Holly Dwyer
Characterization Of Putative Porphyromonas Gingivalis Rna-Binding Proteins, Holly Dwyer
Theses and Dissertations
Porphyromonas gingivalis (P. gingivalis) is a gram-negative, anaerobic bacterium recognized as a major player in progression of periodontal disease. P. gingivalis survives in the oral cavity while being exposed to dynamic environmental conditions such as pH, temperature, nutrient availability and host immune responses such as oxygen tension and nitrosative stress. Survival and pathogenesis of P. gingivalis in the oral cavity require mechanisms to regulate gene expression in response to the extracellular signals. Little is known about the regulatory mechanisms of P. gingivalis in the oral cavity, so it is important to investigate and characterize these regulatory mechanisms. Adaptation to environmental …
