Tumor Targeting Gold Nanoparticles For Delivery Of Rna And Dna Oligonucleotide Therapies For Glioblastoma., Nicholas Allen
Tumor Targeting Gold Nanoparticles For Delivery Of Rna And Dna Oligonucleotide Therapies For Glioblastoma., Nicholas Allen
Electronic Theses and Dissertations
Glioblastoma (GBM) brain tumors are highly aggressive gliomas due to genetic and cellular heterogeneity. Current GBM treatment consists of surgical resection of the tumor combined with radio- or chemo-therapies. While these treatments have increased the life expectancy for GBM patients up to 20 months, they have had little effect on the 5-year survival rate. The complex cellular and genetic composition of the tumor makes current treatments less effective long term. One approach to developing more effective GBM treatments is to customize nanoparticle-based drug delivery systems that can directly target the aberrant gene expression patterns within a particular GBM tumor. Delivery …

Understanding The Role Of Antioxidant Nanoparticles In Improving The Outcome Of Secondary Injury In Traumatic Brain Injury, Aria W. Tarudji
Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research
Following traumatic brain injury (TBI), excess reactive oxygen species (ROS) and other free radicals are released, inducing the cascade of secondary injury that exacerbate the outcomes of TBI. Antioxidant nanoparticles (ANPs) have shown promising outcomes in reducing the progression of TBI, which may be due to the higher accumulation and retention of ANPs in the injured brain. However, there is limited knowledge of: 1) antioxidant activities needed in TBI treatment, 2) correlation between longer retention, bioavailability, and target engagement with antioxidant treatments, and 3) sexual dimorphism to ANP treatments.
This dissertation assesses multiple ANPs with various scavenging activities and durations …

Development Of Fluorescent Hyaluronic Acid Nanoparticles For Intraoperative Tumor Detection, Nicholas E. Wojtynek
Theses & Dissertations
Surgical resection remains to be the primary treatment for the majority of solid tumors, including breast cancer. The complete removal of the primary tumor, local metastases, and metastatic lymph nodes dramatically improve a patient’s treatment outcome and prognosis. Nevertheless, surgeons are limited to tactile and visual cues in distinguishing malignant and healthy tissue. This can result in a positive surgical margin (PSM), which occurs when tumor goes undetected and is left behind in the surgical cavity. PSMs decreases a patient’s prognosis and necessitate additional treatment in the form of surgery, radiation, and chemotherapy. An emerging imaging modality, known as fluorescence-guided …

A Ph-Sensitive Delivery System For The Prevention Of Dental Caries Using Salivary Proteins, Yi Zhu
Electronic Thesis and Dissertation Repository
Dental caries remains one of the most common chronic diseases worldwide. Salivary proteins such as histatins have demonstrated biological functions directly related to tooth homeostasis and prevention of dental caries. However, histatins are susceptible to the high proteolytic activities in the oral environment. Therefore, pH-sensitive chitosan nanoparticles (CNs) have been proposed as potential carriers to target major oral diseases that occur under acidic conditions (e.g. dental caries and dental erosion). Four different types of chitosan polymers were investigated and the optimized CNs successfully loaded histatin 3 and released it selectively under acidic conditions. Through loading the survival time of histatin …
