Yesterday I had the pleasure of attending Steve Van Sickle's<br>
presentation at SENS6, reporting his results with cryonic preservation<br>
of kidneys. Steve developed a technique for persufflation of organs<br>
perfused with cryoprotectants using cold helium. He was able to cool<br>
pig kidneys to liquid nitrogen temperature, achieving total<br>
vitrification while *avoiding* fractures! I was absolutely floored by<br>
his work, easily the most important presentation at SENS6 so far.<br>
Steve also described calculations for hyperbaric persufflation, which<br>
might allow vitrifying a human body in *a few minutes*!<br>
<br>
Needless to say, if this work pans out, it would dramatically change<br>
the world of cryonics. There used to be three obstacles preventing<br>
reversible cryonic suspension - fractures, cryoprotectant toxicity,<br>
and rewarming issues (crystalization). Steve solved the fractures<br>
issue and with the dramatically shorted cooling and even more<br>
dramatically shorter thawing times there might be enough of a<br>
reduction in cryoprotectant toxicity and rewarming injury that<br>
reversible suspension might be within reach (give or take 10 million<br>
dollars worth of development work).<br>
<br>
The presentation video should be available on the SENS site at some<br>
point, check it out.<br>
