Annexin A5-Conjugated Polymeric Micelles For Dual Spect And Optical Detection Of Apoptosis, Rui Zhang Dec 2011

Annexin A5-Conjugated Polymeric Micelles For Dual Spect And Optical Detection Of Apoptosis, Rui Zhang

Dissertations & Theses (Open Access)

Apoptosis, a form of programmed cell death, is critical to homoeostasis, normal development, and physiology. Dysregulation of apoptosis can lead to the accumulation of unwanted cells, such as occurs in cancer, and the removal of needed cells or disorders of normal tissues, such as heart, neurodegenerative, and autoimmune diseases. Noninvasive detection of apoptosis may play an important role in the evaluation of disease states and response to therapeutic intervention for a variety of diseases. It is desirable to have an imaging method to accurately detect and monitor this process in patients. In this study, we developed annexin A5-conjugated polymeric micellar …


Echogenic Liposomes For Nitric Oxide Delivery And Breast Cancer Treatment, Soo Yeon Lee Female Aug 2011

Echogenic Liposomes For Nitric Oxide Delivery And Breast Cancer Treatment, Soo Yeon Lee Female

Dissertations & Theses (Open Access)

Liposomes, also known as nontoxic, biodegradable, and non-immunogenic therapeutic delivery vehicles, have been proposed as a carrier for drugs and antitumor agents in cancer chemotherapy. Echogenic liposomes (ELIP) have the potential to entrap air or bioactive gas to enhance acoustic reflectivity in ultrasound and are used as a contrast agent. The innovative part of this study is based on a novel concept to encapsulate nitric oxide (NO) gas into ELIP, deliver it to breast cancer cells, and control its release via direct ultrasound exposure. Studies on the effect of NO in tumor biology have shown that a high levels of …
