Mechanistic Insight Of The Role Of Nherf1 In Cisplatin-Induced Acute Kidney Injury., Adrienne M. Bushau-Sprinkle
Mechanistic Insight Of The Role Of Nherf1 In Cisplatin-Induced Acute Kidney Injury., Adrienne M. Bushau-Sprinkle
Electronic Theses and Dissertations
Background. Acute kidney injury (AKI) develops in 30% of patients who receive cisplatin, a widely used chemotherapeutic agent. We previously showed that NHERF1 loss resulted in increased susceptibility to cisplatin nephrotoxicity. The overarching goal of this dissertation was to elucidate mechanisms of susceptibility to cisplatin-induced AKI, specifically the effects of NHERF1 loss on tubule cell metabolism, tubule cell mitochondrial function, and alterations in oxidative state and/or renal handling of cisplatin. Methods. 2-4 month male wild type (WT) and NHERF1 knock out (KO) mice were treated with either vehicle control or cisplatin (20 mg/kg dose IP) for 4, 24, and 72 …
Oral Health-Related Quality Of Life In Us Adults With Type 2 Diabetes., Giang Truong Vu
Oral Health-Related Quality Of Life In Us Adults With Type 2 Diabetes., Giang Truong Vu
Electronic Theses and Dissertations
This dissertation focused on the relationship between type 2 diabetes (T2DM) and oral health-related quality of life (OHRQoL) and the factors associated with this relationship in the US. The objectives of the dissertation research were a three-part process: (1) to understand the relationships of T2DM with poor OHRQoL, clarify risk and preventive factors that affect this association, and identify research gaps in the literature, (2) to analyze risk factors associated with poor OHRQoL in US adults with T2DM using a nationally representative random probability cluster sample, and (3) to apply structural equation modeling (SEM) to a simplified Andersen’s Behavioral Model …
Transient Display Of Chimeric Proteins On Biological Surfaces As An Effective Strategy For Modulations Of Innate And Adaptive Immune Responses., Pradeep Shrestha
Transient Display Of Chimeric Proteins On Biological Surfaces As An Effective Strategy For Modulations Of Innate And Adaptive Immune Responses., Pradeep Shrestha
Electronic Theses and Dissertations
The major premise of this dissertation was to transiently display novel immunological ligands on biological membranes as a localized means of modulating innate and adaptive immune responses with applications to bone marrow and pancreatic islet transplantation. In Chapter two, we engineered donor allogeneic bone marrow cells to transiently display a novel form of FasL, SA-FasL, to efficiently purge out alloreactive donor T cells to prevent acute GVHD. In Chapter three, we engineered pancreatic islets with a novel form of CD47, SA-CD47, to modulate instant blood mediated inflammatory reaction (IBMIR) to prevent immediate islet graft loss following intraportal transplantation. GVHD is …
Sulforaphane Protects Against Ethanol-Induced Apoptosis And Teratogenesis Through Epigenetic Modulation Of Anti-Apoptotic Genes., Yihong Li
Electronic Theses and Dissertations
Background. Ethanol-induced excessive apoptosis in neural crest cells (NCCs), a multipotent progenitor cell population, is one of the major mechanisms underlying the pathogenesis of Fetal Alcohol Spectrum Disorders (FASD). However, the molecular mechanisms underlying FASD that results from maternal alcohol exposure during pregnancy are poorly understood. The overall goals of this study are to examine the mechanisms by which ethanol induces apoptosis and malformations in vitro and in vivo, and to develop a nutritional-based approach by using SFN and SFN-rich BSE to prevent FASD through epigenetic modulation. Results. This study demonstrates that ethanol exposure resulted in a significant increase …
Hearing Loss: Investigating The Comfort, Confidence, Knowledge, And Preparedness Of Kentucky School-Based Speech-Language Pathologists., Amanda Matsumoto
Hearing Loss: Investigating The Comfort, Confidence, Knowledge, And Preparedness Of Kentucky School-Based Speech-Language Pathologists., Amanda Matsumoto
Electronic Theses and Dissertations
Due to advances in technology, the number of users with hearing devices have increased. These users are often mainstreamed into classrooms with typical hearing peers. However, even with these devices, speech and language impairments may still persist. This study was conducted to analyze school-based speech-language pathologists’ (SLP) comfort, confidence, knowledge, and preparedness in treating students with hearing loss in Kentucky schools. 48 SLPs practicing in all levels of school including elementary, middle, and high, completed an anonymous online survey through the Qualtrics® platform. Responses were received from SLPs representing 11 out of the 15 regions throughout Kentucky. Spearman’s rank …
A Novel Approach To Hiv Prevention: Understanding Multi-Level Influences On Hiv Pre-Exposure Prophylaxis (Prep) Uptake And Outreach Among African Americans., Suur Debrah Ayangeakaa
A Novel Approach To Hiv Prevention: Understanding Multi-Level Influences On Hiv Pre-Exposure Prophylaxis (Prep) Uptake And Outreach Among African Americans., Suur Debrah Ayangeakaa
Electronic Theses and Dissertations
This dissertation examined and provided basis for addressing factors related to HIV pre-exposure prophylaxis (PrEP) engagement, outreach, and uptake among high-risk African American youth groups in Louisville, KY. This qualitative dissertation study was designed through the lens of an interpretive framework of social constructivism which holds that multiple realities and interpretations exist and are socially constructed through the lived experiences of individuals and their interactions with others. Thus, lived experiences of various African American youth groups in Louisville as well as key informants of AIDS service organizations (ASOs) across the U.S. (including Louisville) were explored to develop a deeper understanding …
The Role Of Inter-Enlargement Propriospinal Neurons In Locomotion Following Spinal Cord Injury., Courtney Therese Shepard
The Role Of Inter-Enlargement Propriospinal Neurons In Locomotion Following Spinal Cord Injury., Courtney Therese Shepard
Electronic Theses and Dissertations
The focus of this dissertation is to explore the functional role of two anatomically-defined pathways in the adult rat spinal cord before and after spinal cord injury (SCI). To do this, a TetOn dual virus system was used to selectively and reversibly silence neurons with cell bodies at spinal segment L2 and projections to spinal segment C6 (long ascending propriospinal neurons, LAPNs) and neurons that originate in the C6 spinal segment and terminate at L2 spinal segment (long descending propriospinal neurons, LDPNs). This dissertation is divided into five chapters. Chapter One provides background information regarding spinal cord injury, locomotion, …
Autism Spectrum Disorder: Investigating Predictive Adaptive Behavior Skill Deficits In Young Children., Emma L. Feige
Autism Spectrum Disorder: Investigating Predictive Adaptive Behavior Skill Deficits In Young Children., Emma L. Feige
Electronic Theses and Dissertations
Autism Spectrum Disorder (ASD) is a lifelong neurodevelopmental disorder that consists of difficulties with social communication and language, as well as the presence of restricted and repetitive behaviors. These deficits tend to present in early childhood and usually lead to impairments in functioning across various settings. Moreover, these deficits have been shown to negatively impact adaptive behavior and functioning. Thus, early diagnosis and intervention is vital for future success within this population. The purpose of this study was to further examine the subscales that comprise the adaptive behavior section of the Bayley-III to determine which of the ten subscales are …
The Role Of Slc7a11 In Controlling Extracellular And Intracellular Redox Environments Of Lung Fibroblasts - Potential Targets For Intervention In Aging And Idiopathic Pulmonary Fibrosis., Yuxuan Zheng
Electronic Theses and Dissertations
Idiopathic pulmonary fibrosis (IPF) is a fatal lung disease characterized by extracellular matrix deposition by fibroblasts. Aging and oxidative stress increase the susceptibility to IPF. Redox couples, cysteine/cystine (Cys/CySS) and glutathione/glutathione disulfide (GSH/GSSG), and their redox potentials (Eh) quantify oxidative stress. Fibroblasts from old mice maintain more oxidized extracellular Eh(Cys/CySS) than young mice. Microarray shows down-regulation of Slc7a11 potentially mediates this age-related oxidation. Slc7a11 is the key component of system Xc-, an antiporter that imports CySS and exports glutamate. The first aim of this dissertation is to investigate the mechanistic link between Slc7a11 …
