Assessment of Mechanical and Hemodynamic Vascular Properties using Radiation-Force Driven Methods
… clinically-accepted,</p><p>ultrasound-based flow velocity estimation techniques (color-flow Doppler and spectral-</p><p>Doppler imaging) with ARF-based elasticity characterization of vascular tissue. Techniques</p><p>for integrating B-mode, color-flow Doppler, and ARFI imaging were …

CD21 and CD24 Co-expression: A Translational Model between Mouse and Human
… co-expression of CD21 and CD24, determined by 7-color flow cytometry, can be used to demarcate developmental subsets of B cells. A comparison of analogous B cell subsets in mice and humans showed that the B cell subsets distribution differs between the species suggesting differences exist in …

Backscatter Spatial Coherence for Ultrasonic Image Quality Characterization: Theory and Applications
… imaging, and 3) adaptive wall filtering in color flow imaging. </p><p>A novel image quality metric, known as the lag-one coherence (LOC), was introduced along with the theory that relates LOC to channel noise and the conventional image quality metrics of contrast and contrast-to-noise ratio …

Development of a Flow Cytometry Method for the Identification and Enumeration of Enterococcus faecalis
<p>A multi-color flow cytometry method coupled with fluorescent staining was developed to detect and quantify <em>E. faecalis</em> concentrations in coastal waters as an alternative to the traditional membrane filtration method. The developed method was used to characterize <em>E. faecalis …

Recruitment of monocytes to the pre-ovulatory ovary
… (hCG) injection and analyzed by multi-color flow cytometry. Oviducts were collected from mice 20 hours after hCG administration and cumulous oocyte complexes were collected, counted and averaged to determine ovulation rate. Immunohistochemistry was used to determine the location of …

A Flow Cytometric Analysis of Immunocyte Populations in Peripheral Blood and Pleural Effusions of Patients with Cancer
<p>Two-color flow cytometric analysis was performed on paired samples of peripheral blood (PB) and pleural effusions (PE) of patients with metastatic malignancies. The purpose of these analyses was to test the hypothesis that there are significant differences in the distribution of immunocyte …

The Role of Map Kinases On The Functional Heterogeneity of Human Cd8+ T Cell Maturation Subsets
… of late memory CD8+ T cells, I optimized multi-color flow cytometry techniques to assess the cytokine production of each human CD8+ T cell maturation subset. I demonstrated that late memory CD8+ T cells are the predominant producer of CC chemokines (e.g. MIP-1β), but rarely produce IL-2; …

Ultrasound-based Noninvasive Monitoring Methods for Neurocritical Care
… extra- and transcranial volumetric blood flow measurement and for embolus detection and embolic load quantification. The blood flow waveform measurements were also used to determine intracranial pressure (ICP), intracranial compliance (ICC), and cerebrovascular resistance (CVR) in a …

Next generation approaches toward engineering therapeutic proteases
… of Tyr was made possible by implementing a multi-color flow cytometric assay using multiple simultaneous counter-selection substrates for the screening of large mutant libraries. While primary sequence recognition may suffice for proteomic applications, many therapeutic applications of engineered …

Spatiotemporal excitation sequence manipulation and processing for Doppler ultrasound and pulse-echo sound speed imaging applications
Over the past several decades, plane wave based ultrasonic imaging applications have dominated the research landscape in biomedical ultrasonography. This is predominantly due to the inherent advantages of coherent plane wave compounding, in which steered plane waves are coherently summed to …

Influenza a virus gene expression heterogeneity regulates viral superinfection potential and host innate antiviral response
… By combining single particle infection and multi-color flow cytometry, I directly assessed the effects of individual IAV genes on superinfection efficiency and revealed that superinfection susceptibility is negatively correlated with the quantity of viral gene segments expressed within an infected …

ROLE OF NATURAL KILLER CELLS IN THE PATHOGENESIS OF PRIMARY BILIARY CHOLANGITIS
… based on their response to UDCA. By using a 23-color flow cytometry panel, we characterized and compared the frequencies and phenotype of NK cell subsets in the PB and liver from PBC patients and HDs. We also investigated differences in the immunophenotype of circulating NK cells from PBC …

Engineering soluble, high affinity T cell receptor domains for detection of staphylococcal and streptococcal exotoxins
… of SEA. In Chapter 3, a bead-based, two-color flow cytometry approach was used to develop a multiplex assay for simultaneous detection of staphylococcal (SEA, SEB and TSST-1) and streptococcal (SpeA and SpeC) toxins in a single sample. Vβ domains that were engineered for for binding with …
