tailieunhanh - CORONARY ANGIOGRAPHY – THE NEED FOR IMPROVEMENT IN MEDICAL AND INTERVENTIONAL THERAPY

Heat transport limitation in larger tissue may also affect survival. Due to the macroscopic size of tissue-engineered products and its finite thermal conductivity, there may be large thermal gradients from the surface to the interior of the samples. The presence of a thermal gradient during cooling and warming phases makes it difficult to choose optimal temperature change protocols for both surface and interior cells. Moreover, osmotic effects (water movement from inside-unfrozen cells to outside-frozen cells) during cooling, reduces cell survival. Accordingly, it may not be possible to recover full viability throughout the tissue (Karlsson and Toner, 1996) | CORONARY ANGIOGRAPHY - THE NEED FOR IMPROVEMENT IN MEDICAL AND INTERVENTIONAL THERAPY Edited by Branislav Baskot Coronary Angiography - The Need for Improvement in Medical and Interventional Therapy Edited by Branislav Basket Published by InTech Janeza Trdine 9 51000 Rijeka Croatia Copyright 2011 InTech All chapters are Open Access articles distributed under the Creative Commons Non Commercial Share Alike Attribution license which permits to copy distribute transmit and adapt the work in any medium so long as the original work is properly cited.
