Is Ischemia Reperfusion Injury Immediately after Heart Transplantation Correlated to Increased Intimal Thickening in the First Year?
J. Patel, M. Kittleson, D. Chang, E. Kransdorf, D. Geft, A. Shen, K. Nishihara, A. Velleca, L. Czer, F. Esmailian, J. A. Kobashigawa
Cedars-Sinai Smidt Heart Institute, Los Angeles, CA
*Purpose: Ischemia reperfusion injury (IRI) is not uncommon in heart transplant patients due to high dose inotropes, ischemic time, and technical surgical reasons. Ischemia in…

Accomplishment of Ischemia-Free Kidney Transplantation Using Normothermic Machine Perfusion
G. Chen, X. He, C. Wang, X. Yuan, M. Han, Z. Guo
Organ Transplant Center, The First Affiliated Hospital of Sun Yat-sen University, Guangzhou, Guangdong, China
*Purpose: Ischemia-reperfusion injury (IRI) has been considered an inevitable event in organ transplantation since the first successful kidney transplant was performed in 1954. To avoid…

Nanodiamond-Doxorubicin Complexes Improve Hepatic Ischemia/Reperfusion Injury
A. Kobayashi, C. Grady, S. Duarte, V. Boominathan, S. Shrestha, A. Zarrinpar
Surgery, University of Florida, Gainesville, FL
*Purpose: Hepatic ischemia/reperfusion injury (IRI) is a major inflammatory event in liver transplantation that is mediated by oxidative stress. Doxorubicin (DOX) can mitigate oxidative stress…
