Topoisomerase And Tyrosyl-Dna-Phosphodiesterase Ratio As An Indicator For The Response Of Glioblastoma Cancer To Topoisomerase Targeting Anticancer Drugs, Wenjie Wang
FIU Electronic Theses and Dissertations
Glioblastoma (GBM) patients have an estimated survival of ~15 months, with the standard of care (surgery, radiation, and chemotherapy) that has only modestly enhanced patient survival. Identifying biomarkers representing vulnerabilities in GBM biology may allow for the selection of effective and safe chemotherapy options. Irinotecan (IRT), a genotoxic compound currently in clinical trials for GBM, targets topoisomerase I (TOP1) by forming an irreversible ternary DNA-TOP1 cleavage complex (TOP1cc) and leads to apoptosis. Tyrosyl-DNA phosphodiesterase 1 (TDP1) is a crucial repair enzyme that rescues TOP1cc and reduces the effectiveness of IRT. In the current study, we evaluate the value of the …

Nanofabrication And Spectroscopy Of Magnetic Nanostructures Using A Focused Ion Beam, Ali Hadjikhani
FIU Electronic Theses and Dissertations
This research used a focused ion beam in order to fabricate record small nano-magnetic structures, investigate the properties of magnetic materials in the rarely studied range of nanometer size, and exploit their extraordinary characteristics in medicine and nano-electronics. This study consists of two parts: (i) Fabrication and study of record small magnetic tunnel junctions (ii) Introduction of a novel method for detection of magnetoelectric nanoparticles (MENs) in the tissue.
A key challenge in further scaling of CMOS devices is being able to perform non-volatile logic with near zero power consumption. Sub-10-nm nanomagnetic spin transfer torque (STT) magnetic tunneling junctions (MTJs) …
