Evaluating The Structural And Functional Consequences Of Traumatic Joint Injury And Their Relation To Nf-Κb In A Non-Invasive Model Of Post-Traumatic Osteoarthritis, Ian Matthew Berke
Evaluating The Structural And Functional Consequences Of Traumatic Joint Injury And Their Relation To Nf-Κb In A Non-Invasive Model Of Post-Traumatic Osteoarthritis, Ian Matthew Berke
McKelvey School of Engineering Theses & Dissertations
Post-traumatic osteoarthritis (PTOA) is a painful and debilitating disease of the synovial joint, characterized by degenerative changes to various joint tissues following traumatic joint injury. While several risk factors have been identified in the symptomatic progression of PTOA following injury, inflammation and NF-κB mediated changes are believed to significantly contribute to symptomatic joint dysfunction and pain. However, the temporal presentation of these pro-inflammatory signals following clinically relevant injury and their relationship to the development of symptomatic disease have not been thoroughly investigated. Therefore, there exists a critical need to better understand how these early inflammatory events following injury may contribute …
An Injectable Thermosensitive Biodegradable Hydrogel Embedded With Snap Containing Plla Microparticles For Sustained Nitric Oxide (No) Delivery For Wound Healing, Nikhil Mittal
Dissertations, Master's Theses and Master's Reports
After injury, wound healing is a complex sequential cascade of events essential for the proper recovery of the wound without the scar formation. Nitric oxide (NO) is a small, endogenous free-radical gas with antimicrobial, vasodilating and growth factor stimulating properties. NO has wide biomedical application especially in wound healing however, its usability is hindered due its administration problem as it is highly unstable.
In this work, poly (l-lactic acid) microparticles encapsulated with NO donor S-nitroso-N-acetyl-D-penicillamine (SNAP) were prepared using water-in-oil-water double emulsion solvent evaporation method for controlled delivery for NO at the specific site. The NO release from SNAP-PLLA microparticles …
An Array Of Circular Dielectrophoresis Traps To Separate And Charaterize Individual Microparticles From Population, Hwangjae Lee
An Array Of Circular Dielectrophoresis Traps To Separate And Charaterize Individual Microparticles From Population, Hwangjae Lee
Theses and Dissertations
Dielectrophoretic traps have been broadly studied in light of their many advantages of high controllability, ease of operation, and high efficiency. In the previous studies, however, it was challenging to count captured particles or required work to capture particles. In the thesis, an array of circular dielectrophoresis (DEP) traps was developed and tested to manipulate population of microparticles in single particle level. The circular DEP traps enable more precise control of the force field than conventionally used interdigitated electrodes due to its omnidirectional and symmetric properties. The location of the captured microparticle inside the trap was confirmed by both of …
