Prostate Cancer Microparticles As A Next Generation Screening Tool For Prostate Cancer, Khurram M. Siddiqui

Electronic Thesis and Dissertation Repository

Currently available screening tests for prostate cancer (PCa) are neither very sensitive nor specific. Microparticles (MP) are submicron tumor cell fragments released by PCa cells into the circulation and offer a possible means of sampling the tumor. We evaluated the utility of a MP blood test using nanoscale flow cytometry to distinguish patients with PCa from patients with benign prostatic hyperplasia (BPH). We used monoclonal antibodies against prostate specific membrane antigen, gastrin releasing peptide receptor and ghrelin peptide ligand.

We found higher but statistically insignificant, PSMA and Ghrelin dual +ve MP counts in the BPH group. Our results show that …

Managing Uncertainty In Young-Onset Parkinson's Disease, Michael J. Ravenek

Electronic Thesis and Dissertation Repository

Typically considered a disease of old-age, Parkinson’s disease can affect those younger in life, i.e., before the age of 55, when it is referred to as young-onset Parkinson’s disease (YOPD). Using constructionist grounded theory, this research sought to understand how, and why, individuals with YOPD became informed about their disease over time. A total of 39 individuals, who self-identified as living with YOPD, took part in this study which was organized according to four cycles of data collection. These cycles utilized focus groups, in-depth interviews and a private online discussion board, supplemented by 14 autobiographies written by individuals living with …
