Fall 2011
High aspect ratio microelectromechanical structures have been found, in the literature, to collapse due to capillary forces of liquids. In this dissertation, mathematical models are developed to study (i) the collapse of a microstructure represented by a double cantilevered beam (DCB) with a free...

Teleosts rely on innate immunity to protect themselves from pathogens. Colony stimulating factor-1 (CSF-1) and its cognate receptor CSF-1R control survival, proliferation, differentiation and function of macrophages. Recently, a novel soluble form of CSF-1R (sCSF-1R) was identified in goldfish....

Fungal pathogens are recognized by Dectin-1, a pattern recognition receptor expressed on mammalian innate immune cells. Dectin-1 detects β-glucans, which are polymers of glucose that are a main component of the fungal cell wall. While purified, soluble β-glucans have been used in the clinic as...

Characterizing the Role of IL-1β in Macrophage Clearance of Citrobacter rodentium Infection
DownloadFall 2018
Inflammatory Bowel Diseases (IBD) are a group of conditions characterized by chronic inflammation and a dysregulated immune response of the gastrointestinal tract. The etiology is unknown; however, research has indicated a complex relationship between environmental stimuli, genetic...

Dependence of the Interfacial Adhesion between Two Different Types of Material on their Electron Work Function and Electrical Conductivity
DownloadFall 2021
We observed and investigated a novel interfacial phenomenon related to the dependence of interfacial bonding or adhesive force (Fad) between two substances on the difference in their Electron Work Functions (EWF) or Δφ, and developed a model to quantify such a dependence. First, using...

This work provides a guideline for gecko inspired dry adhesive design and simulation. Mechanical property testing for several polymers commonly used in gecko adhesives (Kraton G1657 thermoplastic elastomer, ST-1060, and ST-1087 polyurethane elastomers) allowed hyperelastic and viscoelastic...

Ultrasound imaging has great potential in intraoral diagnosis, due to its portability, low cost, and low safety risks. A couplant is normally placed between transducers and tissues for better ultrasound image quality. If applied intraorally, the couplants should possess good stability in water,...

Effects of macrophages and noggin suppression on the BMP-2-induced osteogenesis of human bone marrow mesenchymal stem cells
DownloadSpring 2011
The osteogenic effects of bone morphogenetic protein-2 (BMP-2) on human mesenchymal stem cells (MSCs) are less profound than expected as compared with rodent cells, and supraphysiological dose of BMP-2 is required to achieve desired clinical outcome. The mechanism for this phenomenon is unclear....

Examination of the Regulation of Phosphorylation Events in Macrophage Adhesion and Response to Zymosan
DownloadFall 2012
Macrophages play a central role in innate immunity, most notably in tissue repair, phagocytosis of dead or infected cells, secretion of chemokine and cytokines at sites of infection, as well as the activation of other immune cells. These roles are highly dependent on their capacity to migrate...
