Functional Assessment And Potential Therapeutic Role Of Carbon Monoxide Releasing Molecule-­‐3 In A Rodent Model Of Compartment Syndrome, Al Walid Hamam

Electronic Thesis and Dissertation Repository

Compartment syndrome (CS) is a life and limb threatening condition resulting in long term morbidity. Gold standard treatment of CS is surgical fasciotomy. Long-term morbidity is common post fasciotomy. We tested a gait analysis system (CatWalk™) to see if we could detect functional effects of CS in our rodent model. We also investigated the effects of carbon monoxide releasing molecule-3 (CORM-3) on the function of gait in rodents post CS.

The CatWalkTM system was able to detect abnormalities in a rodent’s gait post CS. CORM-3 was also found to alleviate the functional deficits following CS. Multiple dose but not single …

Genomic Predictors Of Drug Response To The Alpha-Specific Phosphoinositol 3-Kinase (Pi3ka-Alpha) Inhibitor Byl719 In Head And Neck Cancers, Giananthony T. Rizzo

Electronic Thesis and Dissertation Repository

PIK3CA is the only frequently mutated, druggable oncogene in head and neck squamous cell cancer (HNSCC), with PIK3CA point mutations and gene amplification rates of 17.5% and 40% respectively, with higher rates in HPV-positive disease. The objective of this research was to determine the effects of BYL719, an α-specific PI3K inhibitor in HNSCC cell lines.

All cell lines with PIK3CA hotspot point mutations or gene amplifications will be sensitive to BYL719.

Twenty-eight HNSCC cell lines were subjected to increasing concentrations of BYL719 and cell viability was measured over time. Cell lines were screened for activating PIK3CA hotspot mutations and amplifications …

Anti-Gd2 Etoposide-Loaded Immunoliposomes For The Treatment Of Gd2 Positive Tumors, Brandon S. Brown

Dissertations & Theses (Open Access)

Systemic chemotherapeutics remain the standard of care for most malignancies even though they frequently suffer from narrow therapeutic index, poor serum solubility, and off-target effects. Monoclonal antibodies that specifically bind antigens overexpressed on many tumors such as the ganglioside, GD2, can be conjugated to drug-loaded liposomes to create a targeted drug delivery system. In this study, we have encapsulated etoposide, a topoisomerase inhibitor effective against a wide range of cancers, in surface modified liposomes decorated with anti-GD2 antibodies. We characterized the properties of the liposomes using a variety of methods including dynamic light scattering, electron microscopy, and Fourier transformed infrared …
