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...
Article: Global Environments My Blog Title: What Scientific Ways to Cope with Global Environment Issues? PDF Consulted References is in What Are Global Environment Issues? Scientists, United Nations, and National Regulation find scientific ways to deal with global environment issues. Recent science method is to convert plastic waste into asphalt road substance. This process will divert plastic waste from disposal in the ocean to on-land road construction material. The RMIT University-led project—supported by the Australian Research Council incorporates the recycled plastic waste from consumers and industries into asphalt road mixture. The recycled substance from plastic waste is more durable in rutting and fatigue resistance than conventional asphalt material. To tackle global Carbon Dioxide emission, sustainable development projects have been initiated by United Nations. The objective is to reduce worldwide Carbon Dioxide released into the atmosphere. Reduction in CO2 emissi...
