Investigation Of Cardiovascular Tissue Following 56fe-Radiation And Potential Countermeasure Effectiveness., Alexandra R Decarlo May 2018

Investigation Of Cardiovascular Tissue Following 56fe-Radiation And Potential Countermeasure Effectiveness., Alexandra R Decarlo

Electronic Theses and Dissertations

Exposure to ionizing radiation is an important medical concern because it can lead to health problems including cancer and cardiovascular issues. In space, astronauts are exposed to ionizing radiation that is not experienced by those who remain on Earth. This radiation can cause health problems such as cardiovascular disease. One way this can happen is through the creation of reactive oxygen species, which can activate TGF-β1, contributing to fibrosis or other cardiovascular problems. Antioxidants can be a potential pharmacological mitigator of these excess reactive oxygen species because of their ability to neutralize reactive oxygen species. One such antioxidant with potential ...


Plga-Modified Nanoparticles For The Treatment Of Hypo-Vascularized Hpv-Related Cervical Cancers., Lee B. Sims May 2018

Plga-Modified Nanoparticles For The Treatment Of Hypo-Vascularized Hpv-Related Cervical Cancers., Lee B. Sims

Electronic Theses and Dissertations

A major challenge associated with delivery of active agents in the female reproductive tract (FRT) is the ability of agents to efficiently diffuse through the cervicovaginal mucosa (CVM) and reach the underlying sub-epithelial immune cell layer and vasculature. A variety of drug delivery vehicles have been employed to improve the delivery of agents across the CVM and offer the capability to increase the longevity and retention of active agents to treat infections of the female reproductive tract. Nanoparticles (NPs) have been shown to improve retention, diffusion, and cell-specific targeting via specific surface modifications, relative to other delivery platforms. In particular ...


Development And Evaluation Of A Biocompatible Electroactive Sensor For Continuous Blood Pressure Measurement., Scott D. Cambron May 2017

Development And Evaluation Of A Biocompatible Electroactive Sensor For Continuous Blood Pressure Measurement., Scott D. Cambron

Electronic Theses and Dissertations

Piezo-active composites have been implemented for sensing and transduction for decades. The 0-3 ceramic/polymer composite is one of the most common composite types used for sensing applications, owing to their tailorable properties of the two-phase composition, consisting of a three-dimensionally connected polymer/rubber matrix (inactive phase) with a dispersion of isolated piezo-ceramic particles (active phase). This thesis describes a method to develop novel biocompatible perivascular band comprised of a two-phase piezo-active composite to be fabricated using simple manufacturing processes. Biomaterials such as tissue scaffolds comprised of silk fibroin (SF) and chitosan (CS), and biocompatible soft rubbers will be implemented ...
