Scientists 'raise the dead' in experiment
12:44pm 27th June 2005 Zombies rising from the dead sound like the stuff of horror films and nightmares - but it could soon be reality.
Scientists have discovered a way to bring dead dogs back to life.

OMG,that is really unbelieveable!!!!! Thanks for the link.
Re: Scientists 'raise the dead' in experiment
hmmm... pet cemetary comes to mind...
But, what a break-through.

I played with Jed, I played with daddy, now I want to play with you mommy. LOL

Eeeee Kryssy! LOL
I freaking love that movie, but it still scares the hell out of me.

Re: Scientists 'raise the dead' in experiment
A friend of mine linked about this on LJ today, as well. It sounds remarkable in any context. They don't mention if they kept the dogs "dead" for more than the stated 3 hours though. Granted, 3 hours is impressive, I'm just thinking long term if they plan on implementing this in humans. In that aspect, 3 hours isn't a very long time to get anything done, specifically in the battlefield example they mentioned. My wife just mumbled something about "playing god, don't you think?" from the living room, but I am inclined to disagree. It's not like cloning, it's a huge leap forward in being able to preserve a life, and if that means "playing god", than I suppose all modern medicine is exactly that.
I'm not that knowledgable about cryogenics (would this be considered that since the solution is freezing?) but again my main question here would be "how long"? What length of time can the saline be kept in so that it continues to be a preservative, or before degeneration of any sort begins to set in? The fact they stated that there was no brain damage after 3 hours seems incredible.

Is the Daily Mail prone to a bit of exaggeration? What is described in the article isn't quite the headlines in the Safar Center, the only possible source that was mentioned in the article.
Here's excerpts from an article on saline flushing. It's pretty short-term, needs quick action and intense supervision. Don't start thinking zombies or cold storage hibernation for trips to the stars just yet.
****
To illustrate the potential for hypothermia, Dr. Kochanek described the “suspended animation” approach developed by his colleagues Peter J. Safar, MD, and Samuel Tisherman, MD, for minimizing neurologic damage after massive trauma-induced blood loss. In dog models of exsanguination cardiac arrest, they tested an aortic flush strategy, which he described as a “balloon catheter in the aortic arch, flushed with different solutions … at different temperatures” to reduce brain temperature. Cardiac arrest was induced with electric shock after five minutes of rapid exsanguination; arrest duration was varied from 20 minutes to two hours. Two minutes after initiating arrest, the researchers began an aortic flush with either room-temperature or iced (2°C to 4°C) saline solutions to achieve tympanically measured brain temperatures ranging between 10°C and 36°C. Dogs were then resuscitated with cardiopulmonary bypass and received intensive care for 72 hours.
A 500-mL/kg flush of saline at either room temperature or 4°C following a 20-minute arrest produced brain temperatures of 36°C or 34°C, respectively. This temperature drop is “not profound cooling by any stretch of the imagination,” Dr. Kochanek stressed. But, even this mild cooling normalized outcomes after an arrest of 20 minutes.
.....
The group also explored using larger-volume (up to 500 mL/kg) cold (2°C to 4°C) flushes to achieve various target brain temperatures during a 60-, 90-, or 120-minute arrest. With brain temperatures of 10°C, excellent outcomes after 60- or 90-minute arrest were achieved using this strategy, said Dr. Kochanek. With arrests longer than 30 minutes, damage to other organ systems and the spinal cord distal to the flush did still occur. This damage was mitigated, however, when the researchers proceeded to “first flush the brain, reach target temperature, then pull the catheter back and continue flushing,” Dr. Kochanek pointed out.
Re: Scientists 'raise the dead' in experiment
I'd do it for my dogs! I don't know about people though, we have a haibt of talking back and people who talk after coming back from the dead would be a little creepy to me.
Re: Scientists 'raise the dead' in experiment
Not really reviving the dead as much as preventing death from happening in the first place...but interesting.
Re: Scientists 'raise the dead' in experiment
They need to perfect it, find a way to automate it, Set it up in a compact form, shield it from radiation, and use it to send humans to Mars and beyond.
Just launch, then konk the astronauts out till arrival.
Re: Scientists 'raise the dead' in experiment
"U.S. scientists have managed to revive dead dogs to life, by using a technique similar to cryogenation, in which the dogs' blood was drained and replaced by a cold, saline liquid. A couple of hours, their blood was replaced, and an electric shock brought them back to life with no brain damage. ...isn't that how drunks do it using whiskey.
Zombie Dogs " Damaged blood vessels and tissues can then be repaired via surgery The technology will be tested on humans within the next year."
... isn't that temporary murder or something? Or maybe they could make money offering 3 hour trips to hell or heaven. Imagine the stories they could tell when they came back !!!!

Just as we don't have to play against death in twister or deal with the "evil robot us's."

hehehe
that gave me some funny visuals
My dog was hit by a car, over a year ago.
When that happened, I found out how much I loved my dog; I was destroyed without him.
After an extensive surgery he now leads a healthy normal life. He's got a funny walk though... he kinda staggers to the side. Beyond that it's as if nothing happened.
But he lived because He wanted to live.
I don't know if it's right to play God.
But if you think they have a chance of a Good life, why not?
It would have been a shame to put both of us through that for him to never really recover.
I got lucky.

Dead puppies
Dead puppies
Dead puppies aren't much fun
They don't come when you call
They don't chase squirrels at all
Dead puppies aren't much fun
My puppy died late last fall
He's still rotting in the hall
Dead puppies aren't much fun
Mom says puppy's days are through
She's gonna throw him in the stew
Dead puppies aren't much fun
Dead puppies

Re: Scientists 'raise the dead' in experiment
PJ, I have that song in my stuff at work. Don't ask me why. It's fun to play in the morning before we let the custies in. It goes nicely with "Fish Heads".

YES! YES! YES! I love it...wtf has NASA been doing, nothing! We need to explore the universe. God is imaginary, but space exploration is plausible and real!!! Dammit I love you Madcap!;D
Re: Scientists 'raise the dead' in experiment
i have my opinion about 'scientists'. but i'll keep it to myself...
