Subject: brain vitrification

Brian Wowk referenced a paper by Jerry Lemler et al, including studies of  
vitrification results in various mammalian brain segments, using something  
called M22.  I hadn't seen that.
 
It's nice work, and encouraging, but incomplete. No temperatures were  given. 
Also, the statement that organs can now be vitrified seems inconsistent  with 
other information. As far as I know--and I could be behind the times--it is  
still true that not even rabbit kidneys can be vitrified with sufficient  

viability and reliability to warrant use of this technology for human clinical
transplants.
 
Again, Dr. Pichugin's solutions have been tested mainly by the functional  
criterion of the potassium/sodium ratio, a tougher criterion than  microscopy.
Eventually, of course, we would like testing by many different  criteria.
