Using Paired-Agent Imaging To Track Changes In Head And Neck Cancers After Undergoing Photodynamic Therapy Treatment, Reeham M. Choudhury
Using Paired-Agent Imaging To Track Changes In Head And Neck Cancers After Undergoing Photodynamic Therapy Treatment, Reeham M. Choudhury
Dartmouth College Master’s Theses
Head and neck cancers affect thousands of people across the world, and photodynamic therapy (PDT) has been shown to have great potential to treat said cancers in a noninvasive manner. However, imaging head and neck cancers has been difficult, and molecular changes caused by PDT are not well-understood. Therefore, we propose the use of paired-agent imaging (PAI) to track changes in these cancers after after PDT treatment. For these studies, we primarily used benzoporphyrin derivative monoacid (BPD) for our photosensitizer, which is activated by a 690 nm laser. We first looked at changes in EGFR expression in vitro, and …

Biodegradable Electronic And Optical Devices Toward Temporary Implants, Md Shihab Adnan
Masters Theses
"Implantable biomedical devices have a high potential to revolutionize health care technologies in near future. Implantable devices can be classified as permanent prosthetic devices such as pacemakers or nerve stimulants and temporary devices for intermediate monitoring and control scenario which are still in research phase. In contrast to permanent device, temporary implants lose functionality and become unnecessary after intended operational lifetime which may pose serious electromagnetic and biomedical safety concern, latent complications at the implanted sites and possible ethical issues if not removed from body by an additional surgical operation.
The first paper of this thesis focuses on exploring the …
