Enabling Studies To Optimize Biomaterials For The Treatment Of Myocardial Infarction, Eva Adriana Romito
Enabling Studies To Optimize Biomaterials For The Treatment Of Myocardial Infarction, Eva Adriana Romito
Theses and Dissertations
The canonical mechanism of wound healing is disrupted following a myocardial infarction (MI), manifesting as an unregulated response that negatively impacts left ventricular (LV) function. This mechanism, termed post-MI remodeling, culminates in an outcome that favors progression to a systolic heart failure state and death for the patient. Therapeutic approaches following the occurrence of a MI are designed to modulate the natural remodeling process and mitigate the loss of cardiac function. The mechanics and structure of the healing infarct have been the focus of numerous pre-clinical and clinical investigations, leading to the impending clinical introduction of material injections as a …
Orthopedic Drill System With Screw Length Measurement And Heat Sink System, Hunter Wilcox Rafoth, John Patrick Metz
Orthopedic Drill System With Screw Length Measurement And Heat Sink System, Hunter Wilcox Rafoth, John Patrick Metz
Senior Theses
Most orthopedic drills currently on the market are rudimentary tools that serve only one purpose: to drill holes through bone. Biosphinx envisions a more versatile orthopedic drill that could serve multiple purposes in the operating room. This report outlines Biosphinx’s solution to design a new orthopedic drill system that would include several key features to improve bone screw length measurement, increase patient safety, and reduce time spent in the operating room.

Next Generation Electrode, Joseph Daniel Bivona, Samuel Scott Dacus, Mary Harrell, James Frederick Weber Pike
Senior Theses
This senior thesis involves the results of a biomedical engineering senior design project where the group worked with Rhythmlink International LLC. The project involved the improvement of the manufacturing process of the Invisa Electrode, a CT compatible electrode sold and manufactured by Rhythmlink. The design of the electrode pin was altered to have a hollow center, where the lead wire can be inserted and heat welded, eliminating two key components of the original design and reducing production time and cost. The type of plastic used in the electrodes was also altered to be a 40% carbon loaded conductive plastic.
Therapeutic Potential Of Catechins And Derivatives For The Prevention Of Alzheimer’S Disease, Shelby Elaine Chastain
Therapeutic Potential Of Catechins And Derivatives For The Prevention Of Alzheimer’S Disease, Shelby Elaine Chastain
Theses and Dissertations
Alzheimer’s disease (AD) is a neurodegenerative condition that affects 1 in 9 people over the age of 65, an estimated 5.4 million Americans. It is the only disease among the top 10 that cannot be prevented, cured, or treated. Based on the lack of a viable therapeutic for the prevention or cure of AD, it is vital that therapeutic research for AD continues. AD is characterized by the deposition of extracellular neuritic plaques comprised of insoluble amyloid-β (Aβ) fibrils. These plaques are formed from the amyloidogenic aggregation of Aβ monomer, generated from the cleavage of the amyloid precursor protein (APP) …
Automated Image Analysis And Spatial Computational Modeling Of Nf-Kb In Cerebrovascular Endothelial Cells, Kasey Catalfomo
Automated Image Analysis And Spatial Computational Modeling Of Nf-Kb In Cerebrovascular Endothelial Cells, Kasey Catalfomo
Theses and Dissertations
Cerebrovascular endothelial cells play a key part in the inflammatory response of the blood-brain barrier in pathological conditions such as Alzheimer’s disease. Specifically, the NF-κB signaling pathway plays a central role. Better understanding of the factors in inflammatory disease progression can lead to more effective treatments for such devastating illnesses like Alzheimer’s, asthma, arthritis, cancer, diabetes and many more inflammatory diseases. The proposed approach analyzes spatial NF-κB distribution contained in multispectral stacked micrograph images of cerebrovascular endothelial cells indexed based on dose of the activating protein and the length of activation. Image analysis code identifies the location of nuclear boundaries …
A Mechanical Approach To The Characterization Of Material Failure Of Atherosclerotic Lesions, Lindsey A. Davis
A Mechanical Approach To The Characterization Of Material Failure Of Atherosclerotic Lesions, Lindsey A. Davis
Theses and Dissertations
Failure of atherosclerotic plaques can lead to potentially life threatening clinical events such as myocardial infarction (MI), stroke, or transient ischemic attack (TIA). The most frequently described plaque failure mechanism is tensile rupture of the fibrous cap; however, often during angioplasty another plaque failure mechanism occurs in which the atherosclerotic plaque separates from the internal elastic lamina (IEL). This study aims assess the material strength of atherosclerotic lesions using mechanical concepts.
To assess likelihood of plaque dissection at the vessel wall, adhesion strength was assessed in both mouse and human specimens using plaque delamination experiments. Measuring plaque adhesion in transgenic …

A Theoretical Study Of Polymer Based Drug Delivery Systems, Ebtisam Abdullatif Aldaais
Theses and Dissertations
Polymer nanostructured materials for drug delivery applications have witnessed tremendous progress in recent years due to their vast potential. One-end-grafted polymers can form grafted micelles with specific mechanical properties. Biological conditions can alter these properties resulting in the protection or release of drugs. Charged surfactants can also form micelles in an aqueous solution, which can also be manipulated through special conditions. On the micellar surface, self-organized polyelectrolytes can be stimulated to extend their attached ligands and thus increase the probability of binding to targeted receptors. This thesis focuses on modeling polymer-based drug delivery systems by studying the physical interactions between …
