Liquid nitrogen is NOT water, thus the solution is not hypotonic nor hypertonic. No expansion will happen under these conditions. However, if the cell was placed in water and then frozen, of course! but we're not talking about that.zengirl said:What people don't understand is the biggest problem with freezing is cell integrity. People who are placed in liquid nitrogen and frozen with the hopes of being reanimated are wasting their money. When a cell is frozen, the water inside of it expands and damages the cell. Upon thawing, the damaged cell no longer has any structure to it (which is why many things like fresh fruit and such get soggy after you thaw them) I don't understand how people think they can reanimate a brain after it's been frozen, don't they understand biology?

edit: A nice example here would be sperm. Lovely lovely sperm.
In vacular storage, yes, but it must also be surrounded by water to make the transformation zengirl is talking about. The form of freezing she mentioned is used for storing sperm, eggs etc. without denaturizing them.fly said:A cell contains water
I'm speaking of the water that already exists within the cell.Galen said:Liquid nitrogen is NOT water, thus the solution is not hypotonic nor hypertonic.

Of course there's water in the cell, but when it's frozen inhibitors are added to stop it denaturizing. The most crucial stage is thawing where most of the damage can occur if it's not done right.zengirl said:I'm speaking of the water that already exists within the cell.

Kind of like with every movie that's ever been forum hyped. In particular, Sin City. What a pile of dogshit.Drool-Boy said:I saw the movie in question (Land of the Dead) this weekend and I was dissapointed. Not very good at all. I expected so much more.

This is why you should only have to pay after you're thawed.Galen said:Of course there's water in the cell, but when it's frozen inhibitors are added to stop it denaturizing. The most crucial stage is thawing where most of the damage can occur if it's not done right.
Oh it looks very good, but it's lacking in every other aspect. I don't think I'll bother seeing Land of the Dead, just by the name I can tell I won't like it.Drool-Boy said:I actually enjoyed sin city, I dig the syle of it
Land of the dead was just st00pid andpointless
zengirl said:The part I don't understand is how they abate brain damage. Blood supplies oxygen to the brain, generally more than 5 minutes of oxygen deprivation causes irreversible brain damage. It's too complicated for me to understand
I took a bio class like 5 years ago I wouldn't understand what you were saying if you did explain it. Booze killz brain cellz yo.Galen said:I'd attempt to explain it if I had not already switched my brain off for the night. Maybe if this thread is still alive tomorrow I'll have a stab.
You have a good understanding, I -kind- of know the process, at least I've read about it before.zengirl said:I took a bio class like 5 years ago I wouldn't understand what you were saying if you did explain it. Booze killz brain cellz yo.
I dunno man, I used to think I was really smart, and then I sobered upGalen said:You have a good understanding, I -kind- of know the process, at least I've read about it before.
