I was reading slashdot this morning and came across this story :eek:
It seems science really is on the brink of preventing premature deaths
That is weird :eek:
Cool now we dont need computer animations for horror films anymore…
..problem is, a brain without air will getting “destroyed” (die) after 3 minutes + some funny irreparable damages…
… the “revived” lifeform should really act like a zombie then :tongue2:
And for ethical reasons… where am I within the 3 hours of death ? :laugh: (or in this case the dog)
No no no no please dont. 
Reminds me too much of the movie Pet Cemetary
I better love those bionic things, making blind ppl can see again and ppl without arms get robot arms and control em with their brain.
Arrgh! :scared:
Pet Sematary pwned my fear when I was a niblet
It’s a fascinating subject but also very VERY creepy… like you said McCormick… wtf happens to the dog during those 3 hours :scared:
Gah!
Im sure ppl will find out soon :umn: :eureka: and mybe tell us…if its not a too big secret 
Actually, the brain will start decaying ( meaning real damage ) after about 6 minutes without oxygen.
But cases of drowning victims are known, who’ve surviced longer than that without damage, the trick is the cold preserving everything. If you cool the body ( and brain ) cold enough, it’ll go into a preservative state.
There are frogs, who each year freeze ( and physically die ) during the winter and each spring get to life again. Their trick is that they have some kind of fluid in their cells ( glycerol ), which prevents their cells from bursting, once it’s frozen ( as y’all know, water expands when frozen, so when you try to freeze a human, all cells would burst ).
I guess that’s why they inject the dogs with some kind of fluid at slightly above freezing temperature.
It still sounds sci-fi to me, but I would definitely agree that science is getting ahead in huge leaps…
Would you be dead in those hours ?
That would depend on how you define death. If you define death as after life, then no, you wouldn’t be dead, since you come to life again. But clinically the dog is really dead. That’s nothing new though, happened to people too… who’ve been clinically dead for quite a while.
I think that method cannot be used for much longer time than hours.. or days.
As the article says they use almost zero temperature fluid to “froze” body. However even zero celcius (assuming that cells could handle it) doesnt stop all chemical reactions or bacterial activity. I think body continues to “die” slowly while in that condition. Probably no problem at all when its about couple hours but I guess years or decades would be different thing.
I guess “stasis” or “frozen” could be more accurate term instead of “death”…
And as for “what happens meanwhile”: you are either just frozen or in some limbo depending if you believe in supernatural soul or not 
i want to be the first human experiment i could use a nice vacation like that. Then again it might turn out like that bad Mel Gibson movie.
Yes, I read an article on those frogs a yera or so ago and did a quick google to find the following answer to the perplexing question of whether or not a brain needs oxygen in this state…

Q: Do the brain or other organs of the wood frog use oxygen when the frog is frozen?
Charles Byrd
A: During the early stages of freezing the blood continues to deliver oxygen to the tissues. However, once freezing progresses and the circulation fails, the cells must survive without oxygen. They do this by using anaerobic glycolysis, an energy-producing metabolic pathway that does not require oxygen. Lactate, the primary end product of anaerobic glycolysis, accumulates in the blood of frozen frogs. Although little ATP is produced this way, the energy demand in frozen frogs is greatly depressed
In any event, cool article, but so brief… can’t wait to read more on the subject! But my thought was this… imagine implementing it on humans as has been suggested for just a few hours until appropriate medical attention can be given.. what would a doctor tell the patients’ family if they were there? “We are going to suck the blood out of your child/spouse/whatever and in a few hours he may or may not be alive” :scared: Sounds like an emotional rollarcoaster for every1 :eek:
