ASU Electronic Theses and Dissertations


This collection includes most of the ASU Theses and Dissertations from 2011 to present. ASU Theses and Dissertations are available in downloadable PDF format; however, a small percentage of items are under embargo. Information about the dissertations/theses includes degree information, committee members, an abstract, supporting data or media.

In addition to the electronic theses found in the ASU Digital Repository, ASU Theses and Dissertations can be found in the ASU Library Catalog.

Dissertations and Theses granted by Arizona State University are archived and made available through a joint effort of the ASU Graduate College and the ASU Libraries. For more information or questions about this collection contact or visit the Digital Repository ETD Library Guide or contact the ASU Graduate College at gradformat@asu.edu.


The physiological phenomenon of sensing temperature is detected by transient receptor (TRP) ion channels, which are pore forming proteins that reside in the membrane bilayer. The cold and hot sensing TRP channels named TRPV1 and TRPM8 respectively, can be modulated by diverse stimuli and are finely tuned by proteins and lipids. PIRT (phosphoinositide interacting regulator of TRP channels) is a small membrane protein that modifies TRPV1 responses to heat and TRPM8 responses to cold. In this dissertation, the first direct measurements between PIRT and TRPM8 are quantified with nuclear magnetic resonance and microscale thermophoresis. Using Rosetta computational biology, TRPM8 is …

Glycosaminoglycans (GAGs) are long chains of negatively charged sulfated polysaccharides. They are often found to be covalently attached to proteins and form proteoglycans in the extracellular matrix (ECM). Many proteins bind GAGs through electrostatic interactions. GAG-binding proteins (GBPs) are involved in diverse physiological activities ranging from bacterial infections to cell-cell/cell-ECM contacts. This thesis is devoted to understanding how interactions between GBPs and their receptors modulate biological phenomena. Bacteria express GBPs on surface that facilitate dissemination and colonization by attaching to host ECM. The first GBP investigated in this thesis is decorin binding protein (DBP) found on the surface of Borrelia …

Generating amorphous solid dispersions (ASDs) containing active pharmaceutical ingredients has become a favorable technique of emerging prominence to improve drug solubility and overall bioavailability. Cannabidiol (CBD) has now become a major focus in cannabinoid research due to its ability to serve as an anti-inflammatory agent, showing promising results in treating a wide array of debilitating diseases and pathologies. The following work provides evidence for generating homogenous glass phase amorphous solid dispersions containing 50% (w/w) up to 75% (w/w) CBD concentrations in the domain size of 2 – 5 nm. Concentrations up to 85% (w/w) CBD were concluded homogenous in the …
