In Vitro Development of Engineered Lung Tissue
… superior to other matrix options for lung tissue engineering. We will analyze the mechanical integrity of the scaffolds and compare the collagen, elastin, fibronectin, and proteoglycan content of the scaffolds to native tissue. We also use a variety of imaging modalities to study the architecture, …

A Computational Model of Aneurysmal Flow at the Abdominal Aorta
Abdominal Aortic Aneurysm is a dilatation of the aortic artery that occurs in response to degradation of the wall structure. The present research focused on developing a realistic hemodynamic model of the aneurysm using a new method to assign boundary conditions. A three element Windkessel model …

The Influence of Maximal and Submaximal Cyclic Concentric and Eccentric Exercise on Chondrocyte Death and Synovial Fluid Proteins in the Rabbit knee
Excessive joint loading has been associated with the onset and an increased rate of progression of osteoarthritis, but little is known about the effects of exercise loading on synovial fluid (SF) composition and chondrocytes viability. The purpose of this study was to load intact knee joints with …

The Role of Ultrasound Contrast Agents in Producing Sonoporation
This dissertation successfully elucidated the physical mechanism of sonoporation. Oscillation of UCAs near a cell produced microstreaming that resulted in shear stress on the cell membranes. This shear stress resulted in sonoporation, a permeability change that allowed for the uptake of …

Mechanism of C -Cadherin Binding: Multiple Adhesive Alignments and a Multi-Stage Unbinding Trajectory
A preliminary characterization of the structure of membrane supported C-cadherin monolayers, that are used in the surface force measurements, is presented in the latter part of the thesis. Using ellipsometry, we monitor the binding of C-cadherin to lipid monolayers in real time. These data suggest …

Application of the Theory of Elasticity to Modeling of Protein -Dna Interactions
A versatile approach to modeling the conformations and energetics of DNA loops is presented. The model is based on the classical theory of elasticity, modified to describe the intrinsic twist and curvature of DNA, the DNA bending anisotropy, and electrostatic properties. All the model parameters …

In Vivo Fluorometric Assessment of the Skin Microcirculation
A tissue uptake model was developed to describe the fluorescein dermofluorometer signal in terms of the local blood flow and capillary permeability. The fluorescein signal is characterized by a wash-in time constant dependent on both the blood flow and permeability. Under flow-limited conditions …
