Dissertations, Theses, and Capstone Projects
RNA interference (RNAi) is a powerful tool to manipulate the phenotype of an organism by silencing the expression of specific genes and is viewed as a highly promising platform for treating undruggable targets and disorders where small molecule drugs and antibodies would fail. However, development of RNAi based therapies has faced major barriers including cellular and tissue-specific uptake of the Small Interfering RNA (siRNA). Utilizing different nanoparticles as RNAi excipients, cellular uptake and gene silencing potency can be greatly improved. The research in Dr. McDevitt groups has fibrillar carbon nanotubes (CNT) as carriers for siRNA for gene silencing in vitro …

Gamma-Secretase (γ-secretase) is a transmembrane protease of increasing interest, which has been shown to have significant connections to both cancer and Alzheimer’s disease. γ-secretase cleaves both Notch-1, a transmembrane signaling protein, and Amyloid precursor protein (APP), a transmembrane protein whose cleavage may result in the formation of β-amyloid plaques in the brain. Notch-1 and APP are widely studied proteins that have substantial impacts on the development and proliferation of cancer and Alzheimer’s disease, respectively. Notch-1 partakes in the signaling of apoptosis in damaged and mutated cells, thus its cleavage by γ-secretase within the plasma membrane has ramifications on cell growth …

Bioreactors are of interest for value-upgrading of stranded or waste industrial gases, such as CO, CH4, or syngas. Process economics requires reduction of reactor cost and size while maintaining high production rate via rapid delivery of gas feedstock to the liquid phase which in turn requires a high volumetric mass transfer rate (). One strategy to achieve this goal is to increase interfacial area density, a, to >3000 m2 m-3, while minimizing use of energy. Here we show a novel reactor column design that uses a micro-jet array to break feedstock at ambient pressure …
