Thermally Assisted Pulsed Electric Field Ablation For Cancer Therapy, James Michael Hornef
Thermally Assisted Pulsed Electric Field Ablation For Cancer Therapy, James Michael Hornef
Biomedical Engineering Theses & Dissertations
Pulsed Electric Fields (PEF) have promised improved treatment results in a variety of cancer types including melanoma, pancreatic and lung squamous cancer. Recent studies show that PEF-based cancer therapy may be improved further with the assistance of moderate heating of the target. Experiments were performed to design, calibrate and implement a feedback-looped infrared laser irradiation system that could maintain specified temperatures during the treatment. The exact treatment area, penetration depth and thermal distribution of a 980-nm laser fiber were quantified using several methods, including the knife-edge technique and a tissue optical property study. In vivo and in vitro experiments using …

The cell membrane is the interface that volumetrically isolates cellular components from the cell's environment. Proteins embedded within and on the membrane have varied biological functions: reception of external biochemical signals, as membrane channels, amplification and regulation of chemical signals through secondary messenger molecules, controlled exocytosis, endocytosis, phagocytosis, organized recruitment and sequestration of cytosolic complex proteins, cell division processes, organization of the cytoskeleton and more. The membrane's bioelectrical role is enabled by the physiologically controlled release and accumulation of electrochemical potential modulating molecules across the membrane through specialized ion channels (e.g., Na⁺, Ca2+, K⁺ channels). …
