Trends in organ preservation [PDF]

Transplant International, 2003
Organ preservation aims to provide a viable graft with primary function post-transplant. The current basis of preservation for transplantation is static cold storage using specific preservation solutions which minimise cellular swelling and membrane pump activity, thus maintaining cellular ATP levels. The current organ shortage and consequent expansion

Normothermic organ preservation [PDF]

Transplantation Reviews, 2006
Abstract Although organ preservation has relied upon hypothermia throughout the history of clinical transplantation, increasing reliance on suboptimal organs has recently focused attention on novel techniques that avoid the cumulative effects of preexisting organ damage and cold preservation.

Organ reperfusion and preservation

Frontiers in Bioscience, 2008
Organ transplantation is one of the medical success stories of the 20th century. Transplantation is, however, a victim of its own success with demand for organs far exceeding supply. The ischemia/reperfusion injury associated with organ transplantation is complex with interlinking cellular pathways and cascades.

Blockchain-Powered Supply Chain Management for Kidney Organ Preservation [PDF]

arXiv, 2023
Due to the shortage of available kidney organs for transplants, handling every donor kidney with utmost care is crucial to preserve the organ's health, especially during the organ supply chain where kidneys are prone to deterioration during transportation.

Perspectives in Organ Preservation

Transplantation, 2007
Maintaining organ viability after donation until transplantation is critically important for optimal graft function and survival. To date, static cold storage is the most widely used form of preservation in every day clinical practice. Although simple and effective, it is questionable whether this method is able to prevent deterioration of organ ...

Organ preservation: which temperature for which organ? [PDF]

Journal of International Medical Research, 2019
In 1954, Joseph Murray performed the first successful human organ transplant from a live kidney donor, Richard Herrick, into the donor’s twin, Robert. Since no form of organ preservation was available, the surgeries happen in two simultaneous operating rooms.

Experimental organ preservation

Journal of British Surgery, 1972
Abstract An experimental model for the study of organ preservation based on the isolated, biologically perfused rat heart is described. Using this model a standard storage solution has been evolved for use with initial perfusion and hypothermic storage. This solution contains Dextran 40 and insulin.

SA-GAN: Structure-Aware GAN for Organ-Preserving Synthetic CT Generation [PDF]

arXiv, 2021
In medical image synthesis, model training could be challenging due to the inconsistencies between images of different modalities even with the same patient, typically caused by internal status/tissue changes as different modalities are usually obtained at a different time.

Self-organized criticality in deterministic systems with disorder [PDF]

Phys. Rev E 57, 6451 (1998), 1997
Using the Bak-Sneppen model of biological evolution as our paradigm, we investigate in which cases noise can be substituted with a deterministic signal without destroying Self-Organized Criticality (SOC). If the deterministic signal is chaotic the universality class is preserved; some non-universal features, such as the threshold, depend on the time ...

Self-Organizing Time Map: An Abstraction of Temporal Multivariate Patterns [PDF]

Neurocomputing 99(1) (2013), pp. 496-508, 2012
This paper adopts and adapts Kohonen's standard Self-Organizing Map (SOM) for exploratory temporal structure analysis. The Self-Organizing Time Map (SOTM) implements SOM-type learning to one-dimensional arrays for individual time units, preserves the orientation with short-term memory and arranges the arrays in an ascending order of time.
