Functional Significance Of The Upregulation Of Adhesion Molecules On Irradiated Endothelial Cells, Balabhaskar Prabhakarpandian
Functional Significance Of The Upregulation Of Adhesion Molecules On Irradiated Endothelial Cells, Balabhaskar Prabhakarpandian
Theses and Dissertations (ETD)
Ionizing radiation is a major therapy for cancer. Damage to the endothelium and upregulation of inflammatory responses are major side effects of radiotherapy, but the mechanisms behind these processes are not clear. A key component of the inflammatory response is leukocytes adhesion to the endothelium in a multi-step process involving leukocyte tethering to the endothelium, followed by rolling, firm adhesion/spreading and extravasation. Adhesion molecules mediate this process, particularly, E-selectin and ICAM-1, which are inducible adhesion molecules. E-selectin is involved in the initial tethering and rolling steps of the adhesion cascade while ICAM-1 appears to be involved in the latter steps. …

Qualitative Evaluation Of Data Compression In Real-Time Ultrasound Imaging, Bijoy J. Sundersingh
Theses and Dissertations (ETD)
The purpose of this project was to evaluate qualitatively real-time ultrasound imaging using objective and subjective techniques to determine the minimum bandwidth required for clinical diagnosis of various anatomical and pathological states. In the experimental setup live ultrasound video samples representing the most common clinical examinations were compressed at 128, 256, 384, 768, 1152 and 1536 kbps using a compressor-decompressor (CODEC) adhering to International Telecommunication Union (ITU-T) recommendation H.261. A protocol for qualitative evaluation was developed and subjective and objective testing were performed based on this protocol. Subjective methods comprised of inter-rater reliability tests using kappa statistics and three way …
