Characterizing Host And Viral Factors Relevant To Turkey Hemorrhagic Enteritis Virus-Induced Immunosuppression, Abraham Quaye

Theses and Dissertations

Turkey hemorrhagic enteritis virus (THEV) is an adenovirus (AdV) that causes hemorrhagic enteritis (HE) in turkeys, a debilitating disease affecting predominantly 6-12-week-old turkey poults characterized by immunosuppression (IMS) and intestinal lesions leading to bloody diarrhea. Although a naturally-occurring avirulent THEV strain has been adopted as live vaccine and has proven effective at preventing HE in turkeys, it still retains its immunosuppressive ability. Thus, vaccinated birds are rendered more susceptible to opportunistic infections and death than unvaccinated cohorts, leading to substantial economic losses. This dissertation focuses on elucidating both host and viral factors mediating THEV-induced IMS in turkeys. As THEV gene …

Characterizing Gastric Cancer Tumor Immune Microenvironment Through Extracellular Vesicles, Claire Elizabeth Bruno

Theses and Dissertations

The tumor immune microenvironment (TIME) critically influences cancer progression and determining therapeutic response. As immunotherapies continue to improve and reshape cancer treatments, there is a need for tools that can more efficiently and accurately assess and monitor the TIME. Extracellular vesicles (EVs), especially small EVs (sEVs), are lipid-bound nanoparticles that carry proteins, DNA, and RNA reflective of their cell of origin, offering a novel, non-invasive biomarker of the TIME. This makes them a promising candidate for immune profiling and treatment monitoring in cancer. This thesis investigates the potential of EVs as biomarkers for TIME composition and immune activity. An analysis …

Modeling Steady-State Navier-Stokes Flow Using Structure-Preserving Truncated Hierarchical B-Splines, Daira Sofia Velasco Vega

Theses and Dissertations

Accurate simulation of incompressible steady-state fluid flow is critical for engineering applications where mass conservation, numerical stability, and geometric fidelity are essential. This thesis develops and analyzes a structure-preserving isogeometric framework for steady-state incompressible Navier"“Stokes simulations using truncated hierarchical B-splines (THB-splines). By leveraging divergence-conforming spline spaces designed to keep the fluid's divergence exactly zero based on the mathematical de Rham complex, this method ensures the fluid remains incompressible everywhere without needing extra stabilization techniques. The use of THB-splines allows the mesh to be refined locally in areas where the flow changes sharply. It still keeps the solution smooth and ensures …

Faculty, Staff and Students Publications

Cyclin dependent kinases 4 and 6 inhibitors have brought great improvements in the treatment of luminal breast cancer, but resistance is a major clinical hurdle. Multiple biomarkers of resistance have been proposed, but none is currently utilized in clinical practice. By performing single-cell RNA sequencing of seven palbociclib-naïve luminal breast cancer cell lines and palbociclib-resistant derivatives, we show that established biomarkers and pathways related to CDK4/6i resistance present marked intra- and inter- cell-line heterogeneity. Transcriptional features of resistance could be already observed in naïve cells correlating with levels of sensitivity (IC50) to palbociclib. Resistant derivatives showed transcriptional clusters that significantly …
