Click on PDF to download from Part 3 2023: [10.23] The first successful transplant of a functional cryopreserved mammalian kidney was reported. The study demonstrated a "nano-warming" technique for vitrification for up-to-100 days preservation of transplant organs. Sourced from [frontiersin.org] titled: “Supercooling: a promising technique for prolonged preservation in solid organ transplantation, and early perspectives in vascularized composite allografts.” From the perspective of temperature, machine perfusion can be classified into four categories: HMP “hypothermic machine perfusion” (0°C to 12°C), MMP “mid-thermic machine perfusion” (13°C to 24°C), SNMP “subnormothermic machine perfusion” (25°C to 34°C), and NMP “normothermic machine perfusion” (35°C to 38°C). As metabolic activity increases exponentially with increasing temperature, the required amount of oxy...

Sourced from [frontiersin.org] titled: “Supercooling: a promising technique for prolonged preservation in solid organ transplantation, and early perspectives in vascularized composite allografts.” This recent entity started with the first successful forearm allotransplantation in 1998 by Dubernard, followed by the first partial face transplantation led by Devauchelle and Lengelé in 2005 in France. Since then, a few teams had performed more than 130 upper limb transplants, 47 face transplants, 6 penis transplants, and more recently, uterus transplants allowing full-term births. The uterus is where a fetu...
