Drug resistance and toxicity are major obstacles in cancer chemotherapy. Combination therapies can overcome resistance, and synergies can minimize dosing. Polymer nanocarriers are interesting vehicles for cancer therapeutics for their delivery and tumor targeting abilities. We synthesized a multi-layered polymer nanoparticle (MLNP), comprising of(More)
Tandem internal carotid and middle cerebral artery occlusion after carotid dissection predicts poor outcome after systemic thrombolysis. Current treatments include the use of endovascular carotid stenting, which carries with it a high risk of propagating further embolic events and worsening the dissection. New strategies for avoiding the aforementioned(More)
INTRODUCTION Although there have been a few reports of coiling intracranial aneurysms in patients with sickle cell disease (SCD), there are no reports of intracranial stent placement in this patient population. A patient in whom stent placement was utilized as monotherapy to treat a blister-like aneurysm is described and the implications of SCD and(More)
Flow-diverting devices offer an exciting alternative for the management of large and giant intracranial aneurysms. However, the risk and mechanism of delayed aneurysmal rupture and hemorrhage following placement of these devices are not clearly understood. Two patients with similar symptomatic giant paraclinoid internal carotid artery aneurysms are(More)
The majority of commercial sunblock preparations use organic or inorganic ultraviolet (UV) filters. Despite protecting against cutaneous phototoxicity, direct cellular exposure to UV filters has raised a variety of health concerns. Here, we show that the encapsulation of padimate O (PO)--a model UV filter--in bioadhesive nanoparticles (BNPs) prevents(More)
This thesis details two studies using novel approaches to understand kidney transplant outcomes: instrumental variables and social network analysis. Together, these studies demonstrate the value of interdisciplinary approaches to advance the field of kidney trans-plantation. While some studies have found an association between delayed graft function (DGF)(More)
