The Use Of Targeted Charge-Reversal Nanoparticles (Tcrns) To Investigate Nuclear Delivery Of Fluorescent Agents To Cancer Cells: Implications For Novel Prostate And Breast Cancer Therapy, Mario Dance

Theses and Dissertations

Nanotechnology has recently emerged as a strong contributor toward research efforts to develop targeted systems of drug delivery in cancer therapy. Our work investigates the therapeutic potential of Targeted Charge-Reversal Nanoparticles (TCRNs), a novel nanoparticle with in vitro evidence of nuclear drug delivery. Using M12 prostate cancer cells, MDA-MB-231 breast cancer cells, and modified derivatives of these cell lines, we investigated the ability of Folic Acid-tagged TCRNs to deliver Nile Red and Dimethyl Indole Redfluorescent (DiR) fluorescent dyes to the nucleus of cells using confocal microscopy and in vivo biphontonic imaging using Xenogen® Technology. Confocal imaging with the SCP28 derivative …

Oncology Nurses' Impact Scores For Obstacles And Supportive Behaviors At The End Of Life, Joan M. Collett

Theses and Dissertations

Introduction: Oncology nurses provide end-of-life (EOL) care to their patients daily. Oncology nurses' perceptions regarding how to provide quality care to dying patients could be an important addition to the ongoing research on quality EOL care. The purpose of this study was to determine the impact of specific obstacle and supportive behaviors in EOL care as perceived by hospital-based oncology nurses. This study extended the work of Beckstrand, Moore, Callister, and Bond (2009).

Methods: A 69-item questionnaire adapted from previous studies (Beckstrand & Kirchhoff, 2005; Beckstrand, Smith, Heaston, & Bond, 2008) was sent to 1,000 nurses who were members of …

Heat Shock Proteins As Novel Cancer Therapeutics: Targeting The Hallmarks Of Cancer, Chao Li

Theses and Dissertations

Molecular chaperones, commonly known as heat shock proteins (HSPs), are essential for mammalian cells to maintain homeostasis, and HSPs function by inducing an ATPase-coupled structural change, followed by interactions with diverse co-chaperones and over 200 client proteins implicated in many critical signaling networks. These highly expressed HSPs participate in the onset and progression of several human diseases including cancer, and their connection with tumorigenesis has facilitated research and clinical trials related to targeting HSPs as a novel anti-tumor therapy. The predominant mechanism of chaperone inhibition is through either disruption of the HSP association with client protein or an altered binding …
