Analyzing Heat Generated From Electro-Osmotic Flow Utilizing Computational Fluid Dynamics, Jordan Elizabeth Grothe
Analyzing Heat Generated From Electro-Osmotic Flow Utilizing Computational Fluid Dynamics, Jordan Elizabeth Grothe
Honors Thesis
Without extensive vascularization, the transfer of fluid and nutrients through human tissue is limited to diffusion and weak interstitial flow. Electroosmosis, or the flow of fluid driven by an electrical field, has become a promising solution. Scientists have begun applying electricity to human tissue to promote stronger interstitial flow; however, optimization of this process has proven to be a challenge due to ohmic heating. Cells function within a small range of temperatures and exposure to voltages exceeding the threshold will cause cells to degrade and die prematurely. This research seeks to better understand and quantify the range of voltage where …

Cell Mechanics In Cardiovascular Disease And Electrospun Scaffold For Vascular Tissue Engineering, Alex Park Rickel
Dissertations and Theses
Cardiovascular disease (CVD) is the leading cause of death worldwide. Atherosclerosis, one of the primary CVDs, is characterized as a chronic inflammatory disease. In the initial stages of atherosclerosis, there is a buildup of cholesterol and lipoproteins that triggers monocytes to enter the arterial wall and begin accumulating lipids. Vascular smooth muscle cells (VSMCs) begin to detach and migrate from the media toward the intima in a process known as phenotypic switching. Phenotypic switching transitions VSMCs from a contractile to synthetic phenotype and they gain the capacity for migration, proliferation, and secretion of extracellular matrix (ECM) proteins. Synthetic VSMCs experience …

Development Of A Targeted Drug Delivery System For Intracranial Atheroslerotic Disease, Kirby Fuglsby
Dissertations and Theses
Intracranial atherosclerotic disease (ICAD) remains a leading cause of ischemic events such as stroke. However, the use of drug coated balloons (DCBs) containing paclitaxel (PAT) in the brain vasculature remains limited. This is the result of several factors including particulate shed from polymer excipients, PAT toxicity, and poor blood-brain barrier (BBB) permeability of PAT. Therefore, there is a need for novel PAT and excipient formulations for balloon coatings to improve delivery of PAT to the arterial wall in ICAD while reducing off target drug effects and particulate shed. GM1 has previously been shown to cross the BBB and have high …
Framework For The Evaluation Of Perturbations In The Systems Biology Landscape And Inter-Sample Similarity From Transcriptomic Datasets — A Digital Twin Perspective, Mariah Marie Hoffman
Framework For The Evaluation Of Perturbations In The Systems Biology Landscape And Inter-Sample Similarity From Transcriptomic Datasets — A Digital Twin Perspective, Mariah Marie Hoffman
Dissertations and Theses
One approach to interrogating the complexities of human systems in their well-regulated and dysregulated states is through the use of digital twins. Digital twins are virtual representations of physical systems that are descriptive of an individual's state of health, an object fundamentally related to precision medicine. A key element for building a functional digital twin type for a disease or predicting the therapeutic efficacy of a potential treatment is harmonized, machine-parsable domain knowledge. Hypothesis-driven investigations are the gold standard for representing subsystems, but their results encompass a limited knowledge of the full biosystem. Multi-omics data is one rich source of …
