Testing Continuity between Versions 5.3.9 and 6.3.1 of Plaque Simulator for Planning Eye Plaque Brachytherapy Cases

Creator:: Polsdofer, Elizabeth M.
Abstract:: The purpose of this study is to examine the challenges of accepting and commissioning a new treatment planning system for eye plaque brachytherapy. Currently Oregon Health and Science University (OHSU) utilizes v5.3.9 of the Plaque Simulator software to plan all of its eye plaque brachytherapy cases. However, v5.3.9 is no...

Multicellular monolayer’s self-organization under external stimuli

Creator:: Li, Guanyu
Abstract:: Cell signaling under external stimulation is a critical mechanism that governs many biological processes such as cell proliferation, cell migration, and cell apoptosis, etc. For multicellular organisms, the ability to synchronize heterogeneous individual cellular responses through intercellular communication is crucial to maintain normal functionality. However, even though the biological pathways...

Bridging the Gap Between Equilibrium Properties and Ultrafast Dynamics with Time-Resolved Spectroscopy of Functional Systems

Creator:: Krueger, Taylor D.
Abstract:: Ultrafast spectroscopy has recently gained momentum as a powerful, noninvasive characterization toolset capable of studying a diverse array of samples with applications in chemistry, physics, biology, engineering, and more. Two popular ultrafast spectroscopic techniques include femtosecond transient absorption (fs-TA) and femtosecond stimulated Raman spectroscopy (FSRS). The latter of these techniques...

Coulomb Explosion in Moderately Intense Nanosecond Laser Fields

Creator:: Yao, Yuzhong
Abstract:: In this dissertation, I present experimental observations of multiply charged atomic ions (MCAI) generated from interactions of atomic/molecular clusters with moderately intense nanosecond laser pulses. This process is also known as Coulomb explosion (CE) and it has been extensively studied in intense laser fields using ultrashort pulses. Several prevailing theories...

Electron Diffraction of Neutral and Cationic Clusters Doped into Superfluid Helium Droplets

Creator:: Lei, Lei
Abstract:: In this dissertation, I describe the experimental investigation of electron diffraction of neutral and ionic clusters doped into superfluid helium droplets. The project is aimed at contributing to the development of an overall approach called ‘serial single molecule electron diffraction imaging (ss-EDI), a potential approach to solve macromolecule structures bypassing...

Analytical Platform to Study Bacterial Metabolism and their Interactions with Biomaterials using SECM

Creator:: Sheet, Partha S.
Abstract:: The microbial communities play a crucial role in maintaining human health and cause diseases through very complex microbial chemical interactions. Therefore, these microbial communities have drawn much attention to the scientific communities. To elucidate these complex microbial communities and the chemical interactions within it, one or more isolated species of...

Dynamics and Design of Green Fluorescent Protein-Inspired Superphotoacids and Red-Emitting Fluorophores with Transient Absorption and Femtosecond Stimulated Raman Spectroscopy

Creator:: Chen, Cheng
Abstract:: In the past decades, femtosecond stimulated Raman spectroscopy (FSRS) has been gaining tremendous popularity in fundamental sciences stemming from chemistry to biology. It is capable of capturing both equilibrium and non-equilibrium structural information across a broad range of timescales with simultaneously high temporal and spectral resolutions. Femtosecond transient absorption spectroscopy...

Multi-scale Investigation of Bidirectional Feedback Mechanism Between Breast Cancer Cells and Extracellular Matrix

Creator:: Kim, Jihan
Abstract:: Cell migration is fundamental for physiological processes such as immune re-sponses, wound healing and development. It is also a critical characteristic of metastatic cancer cells. An extensive amount of studies have focused on 2D sub-strates in order to understand the mechanism of cancer metastasis. However, much less is known about...

Electrochemical Micro-sensors for Probing Bacterial Metabolic Behavior with Scanning Electrochemical Microscopy

Creator:: Jayathilake, Nadeeshani M.
Abstract:: Dental plaque is one of the well-characterized biofilms in the human body. Oral bacterial species play vital roles in maintaining healthy bacterial homeostasis as well as causing oral infections. Many of the oral diseases are caused by opportunistic pathogens, and therefore, the bacterial metabolic activities become important in dictating their...

In vivo Reactions of Tetrazines Incorporated through Genetic Code Expansion

Creator:: Blizzard, Robert J.
Abstract:: The inverse electron demand Diels Alder reaction between tetrazines and strained alkenes is an exceptionally useful tool in functionalizing to biomolecules since it is orthogonal to the chemistry of most living systems and have exceptionally high rate constants. In particular reactions between strained trans-cyclooctenes (sTCO) and tetrazines can achieve second...
