X-Message-Number: 26743 From: Date: Sun, 31 Jul 2005 10:02:41 EDT 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.
