Digital Twins Of The Living Knee: From Measurements To Model, Thor Erik Andreassen

Electronic Theses and Dissertations

Modern medicine has dramatically improved the lives of many. In orthopaedics, robotic surgery has given clinicians superior accuracy when performing interventions over conventional methods. Nevertheless, while these and many other methods are available to ensure treatments are performed successfully, far fewer methods exist to predict the proper treatment option for a given person. Clinicians are forced to categorize individuals, choosing the best treatment on “average.” However, many individuals differ significantly from the “average” person, for which many of these treatments are designed. Going forward, a method of testing, evaluating, and predicting different treatment options' short- and long-term effects on an …

Other research studies on African American/Black administrators’ lack of representation at PWIs attributed systemic barriers impeding their recruitment and advancement (Jones, 2007; Perna et al., 2007). Furthermore, Levin et al. (2013) suggest minimal progress in hiring African American/Black …

Spatial Structure Formation By The Post-Transcriptional Gene Regulator Rsme In Pseudomonas Fluorescens Pf0-1, Anton Evans

Electronic Theses and Dissertations

Microorganisms are often found in microbial communities we call biofilms. Organisms living in these crowded environments have significant evolutionary pressure to retain access to the resources necessary to sustain life. My research uses the bacterium Pseudomonas fluorescens Pf0-1 to study how organisms evolve strategies to solve this crowding problem as aging colonies repeatedly generate mutant patches. These mutants expand the reach of the colony resulting in decreased local density as they push themselves up to the resource rich surface. These spatial structures result from social interactions between the mutant and the parental cells mediated through extracellular secretions, resulting in the …

Glycerophosphocholine Is Used For Lipid And Phosphate Metabolism By Candida Albicans, Will King

Electronic Theses and Dissertations

The metabolism of phosphatidylcholine (PC), a major eukaryotic membrane lipid, has been shown to be an important aspect of pathogenesis in Candida albicans. Of note, PC turnover product, glycerophosphocholine (GPC), is abundant renal metabolite available within the host. GPC is readily imported by C. albicans, and deletion of the major GPC transporter, Git3, leads to decreased virulence in a bloodstream infection model. Here I have characterized two potential metabolic fates of internalized GPC. The first metabolic fate explored is internalized GPC can be hydrolyzed to release P_i. To determine if GPC import and subsequent metabolism impact phosphate …

Multiphasic Molecular Mechanisms Regulate Expression Of Interleukin 1Β, As Well As Other Immediate-Early Genes, In Monocytes And Macrophages, David Macar

Electronic Theses and Dissertations

Interleukin 1β (IL-1β), an important cytokine in both health and disease, functions as a major proinflammatory mediator of pathological challenges, including involvement in the cytokine storm associated with Macrophage Activation Syndrome, Hemophagocytic Lymphohistiocytosis and the severe secondary effects of SARS-CoV-2 infection. Therapeutic approaches to limiting the effects of IL-1β protein have focused either on specific protein neutralization before release from activated macrophages (by general metabolic inhibitors and inflammasome inhibition) or after release by ligand and receptor obstruction (e.g., Canakinumab, Anakinra and Rilonacept). Although these approaches are efficacious, they inhibit steps after gene expression. Since a single gene expresses …
