Cure For Radiation Sickness Found?
Summit writes "A scientist has claimed to have discovered a radioprotectant that all but eliminates acute radiation sickness even in cases of lethal doses of radiation in tests on rats and monkeys, when injected up to 72 hours after exposure. They also claim the drug, a protein, has no observed negative effects in humans. They have not irradiated any people just yet, but if this turns out to be true, it could mean everything from curing cancer to making manned interplanetary space expeditions feasible... not to mention treatment for radiation exposures in nuclear/radiological accidents/attacks. If this drug works, it would mean a true breakthrough as past experiments with radioprotectants were not particularly promising in any respect." The only source for the story at this time is an exclusive in YNet News, a site with the subtitle "Israel At Your Fingertips." Such a radioprotectant would be huge news for Israel. Make of it what you will.
Finally I can get my hands on some sweet, sweet, Radaway!
Do not argue with an idiot. He will drag you down to his level and beat you with experience.
Actually, the BBC has a less slanted article: http://news.bbc.co.uk/2/hi/health/7341336.stm
There's more information on Medical News today if anyone wants a more medical take on this and a less ... Israeli interpretation (I don't know about you but I'm not too hung up on what nationality the researchers are and am more so interested in the technical details). Their 2008 annual report sheds a lot of insight on this as well. Although this information has been public knowledge since the beginning of the year, it should be interesting to watch their stock fluctuate throughout today.
My work here is dung.
No publication in a real scientific or medical journal.
Further, radiation sickness is difficult to fix. You've got alpha, beta & gamma particles bombarding cells, causing damage all over the place. Chemical bonds are broken, energy is added, and new chemical bonds form.
I really doubt a magic bullet can exist for the many types of cellular damage that can occur in different body systems.
So this can patch you DNA back together after it's been ripped to shreds?
Pardon me, but I'm a bit sceptical.
Why bother with miracle drugs when all you need to protect yourself from radiation is to duck underneath a flimsy wooden desk and cover your head with your hands?
Now nuclear war won't be so bad.
Dude, no! Now you need it more than ever, because they're not afraid of accidentally irradiating your brain while they read your thoughts!
And possibly make the treatment quite ineffective, if it also works on cancer cells.
"The medication works by suppressing the "suicide mechanism" of cells hit by radiation, while enabling them to recover from the radiation-induced damages that prompted them to activate the suicide mechanism in the first place."
So it turns the cell into a cry for attention?
Seriously though, saving cells damaged by radiation sounds like a shortcut to cancer. Is the claim of 'enabling cells to recover' realistic?
Is that the stuff Helo kept shooting up while he was stranded on Caprica?
If you already have cancer, then developing another type of it one or two decades down the road is the least of your worries.
QUOTE : Researchers developed the drug after looking at how some resistant cancer cells are able to withstand radiotherapy.
It works by inhibiting the protein that initiates the cell suicide programme
In other word it does not repair radiation damage (cue the rad away joke), it just stops all the cells where this protein is present to die. Whether there was a good reason for them to die or not. It might be wonderful for radiation treatment, though. The researcher seems conscient of the risk (like new cancer developping).

Essentially everyone, if they don't get have a heart attack, kiss a bus, or otherwise snuff it early, will eventually succumb to cancer. Assuming this stuff isn't extraordinarily expensive or incredibly nasty in some other way, "survival now, cancer later" would be a good deal for all but the oldest radiation exposure victims.
I know this is ./, but seriously, RTFA. It's all in there.
Yes, it would be an effective way to treat cancer. That's why it's being developed.
No, it doesn't affect the cancer cells, too.
In the studies, the potential to actually cause cancer is being investigated. In testing so far, it hasn't happened.

Why post anonymous troll... don't have any confidence in your assertions? Don't want to have your karma blasted?
North Korea is like an ugly step-child who will take every opportunity to get back at his more attractive more successful siblings. That kid nobody likes because they always lie about everything and don't take care of themselves, don't try to get along and are generally miserable and make everyone around them miserable.
Israel is like a self-centered only child who gets all the attention deserved or not and always expects that she gets to go first. The kids she cut in front of long ago despise her but everyone else just takes pity on her as an only child and invite her to their parties to be nice. Sometimes she helps out, if it's in her own interest and then everyone gives her a high five to encourage her to do more for others and be less self-centered...
Two completely different psychologies that can present themselves in similar ways at times... both are isolated in a way and feel threatened by those around them, so they both feel the need to create and put forward a strong defensive front and both over-react when anyone questions them about it. Otherwise, completely different.
Now let's get back on topic.
A fool throws a stone into a well and a thousand sages can not remove it.
Oh, *please* call it RadAway.
It doesn't. Read this: http://news.bbc.co.uk/2/hi/health/7341336.stm

God kills kitten everytime you RTFA
You don't know what you don't know.
If you were published in Science, yeah you'd probably get slashdotted.

No they should have just said American. That's what it presumably says on their passport unless they have dual nationality.... and regardless of this it is utterly irrelevant for the story. Can you imagine the uproar had they said "white, male scientists"?
Not only that but I would imagine that it is somewhat insulting to Americans - are they really that ashamed of being a US citizen that they have to somehow dilute it by mentioning where their family emmigrated from?
First, this isn't new; the company issued a press release on PR Newswire in January 2007.
It has nothing to do with Israel; the work is being done at Cleveland BioLabs in Cleveland, Ohio. The researcher behind this, Andrei Gudkov, is Russian. He was at the National Cancer Research Center in Moscow until 1990, then came to the US and became a professor at the University of Illinois.
This seems to be legitimate; they're in FDA Phase I human testing (safety only, not effectiveness.). That doesn't mean it will work; if it makes it through Phase II, it's real.
Cells first developed radiation damage mechanism to repair UV damage. When photsynthesis evolved, cells wanted to get closer to the sun, yet avoid the effects of UV radiation in an Earth lacking an ozone layer. Ozone depends on free oxygen in the atmosphere which was scarce in the first half of Earth history.
The second inducement was the incorporation of mitochrondria into eucharyote cells. This gave cells ten times the energy they had before to eventually power animal locomotion. However, mitochrondria spew out all kinds of nasty poisons like free oxygen, protons, and high electric fields. Cells had to develop mechanisms to neutralize these.

It's true that it usually doesn't, but it sometimes CAN. A cell that has minor damage will most certainly be repaired. A cell that has major damage will lyse and hopefully be replaced by new cells. But when all of the cells lyse at once, there is no way to replace them fast enough. If you can keep most of the cells alive long enough for some non-damaged cells to proliferate, then you could theoretically have viable organs at the end.
Normally, it's more energy efficient to convert a damaged cell into basic components that can be reused than repair the cell, but the repair mechanisms do exist. Apoptosis can be halted, and things will go on relatively normally. The damaged cells might not work all correctly, but if faced with the option of 'die' or 'maybe die', I'll choose 'maybe die'. Plus, if the dangerous part of radiation therapy can be averted, the cancer I'm liable to get later is a lot easier to deal with.
Consider this - with an effective "cure" for radiation, it ceases to become a bogeyman and people will be a LOT more comfortable with clean, efficient nuclear power stations nearby. It takes out a large leg from the alarmists that try to stop them from being built.
