Development Of Novel Tumor-Targeted Compounds For Boron Neutron Capture Therapy, Micah John Luderer

Arts & Sciences Electronic Theses and Dissertations

Glioblastoma multiforme (GBM) represents the most common primary brain tumor among adults. Despite surgical resection and aggressive chemoradiotherapy regimens, the current 2- and 5-year survival rates are only 27% and 9.8%, respectively. The low survival stems from the poor response to conventional therapy and underscores the critical need to develop new therapeutic approaches for GBM treatment. The high recurrence rate observed in GBM is in part attributed to the hypoxic (poorly oxygenated) tumor microenvironment. Hypoxic tumor conditions have been shown to increase metastasis, promote angiogenesis, and confer resistance to chemotherapy and radiation.

Hypoxic tissues are inherently radiation resistant due to …

Development Of In Situ Forming Hydrogels For Intra-Articular Drug Delivery, Andy Prince

Electronic Thesis and Dissertation Repository

Hydrogels are 3-dimensional crosslinked polymer networks that can absorb significant amounts of water. The physical properties associated with hydrogels affords them resemblance to biological tissues making them good candidates for biomedical applications. Many pharmaceuticals, specifically non-steroidal anti-inflammatory drugs (NSAIDs), have poor aqueous solubility, which limits their bioavailability and efficacy. People suffering from chronic osteoarthritis (OA) are required to frequently take large doses to mitigate pain, which can lead to serious side effects. Hydrogels are good strategies to deliver NSAIDs via articular injection because they can form solid gels in situ. This thesis describes the synthesis, formulation, mechanical testing, in …
