Protein Gel Quickly Stops Bleeding
Stefan vd Linden writes, "An international team of scientists has discovered a substance to heal bleeding wounds within seconds. They're using a solution of protein molecules that self-organizes into a biodegradable gel. Until now they've only tested it on animals, but the tests were highly successful. From the article: 'Some surgeons are already excited about the material. "I see great potential in the eye field, the gastro-intestinal field, and in neurosurgery," says Dimitri Azar, head of ophthalmology at the University of Illinois at Chicago, US. "In the eye, even a drop of blood will blur your vision for a long time," Azar adds. "A material that would stop the bleeding could lead to a paradigm shift in how we practice surgery in the eye."'"
It's called platelets. It was invented long ago. Thank goodness, or I would have died the first time my nose bled...

this would be great... if I cut myself shaving its a real pain in the ass... I have to doctor myself for a good hour to get some litle nicks to stop. My shots to stop bleeding cost around 1,000 bucks a pop, so its not like I can just give myself a shot for a minor nick - granted this won't help with joint bleeds, but hey, as long as they don't charge an arm and a leg for the stuff, i'll be happy.
Now if I could just rub it on the skin to stop joint and muscle bleeds... wow... a gift from heaven?
I already make plenty of that myself, thanks.

Platelets are fine for small wounds, but they don't do much for larger than a small cut. For external cuts I usually stick it together with a little superglue. I don't expect this will be over the counter though..

Shame Hemophiliacs don't have those.
Zagreus sits inside your head, Zagreus lives among the dead, Zagreus sees you in your bed and eats you in your sleep.
What do you do if you have bleeding from the lungs? Apply a tourniquet on the neck...
I hope this can help people with macular degeneration of their eyes.
And as I read elsewhere last night - don't invest in the gauze bandage industry now.
Oh You POS
Well, unless my Google search fails me (no, I'm not a native English speaker, and I didn't know what platelets are), platelets are cells. As such, calling them "protein gel" is quite a stretch, since there happens to be more than proteins inside them. Besides, the idea is to stop bleeding quickly, and platelets aren't that fast.
Correction: I think hemophiliacs do have those, it's a different substance they don't have. I'm a little rusty with my genetic disorders. Rooked_One, if you could correct me on this, that'd be great.

This reminds me of when I was watching the cannon run on the Edinburgh tattoo a few years ago. One of the soldiers got hit on his head (#1 haircut), and cut quite badly. A medic ran out with a thing that looked like a staple gun, sprayed it with 'numbing spray', stapled the wound closed with about three staples, then wiped some kind of gel/wax on it. The guy looked a little sore, but he wasn't bleeding and his wound was closed enough that he could carry on. - all in about 10 seconds.
But they do have them. The real problem in hemophilia is with clotting factors, associated proteins that bind the platelets together and stick them in place, rather than a lack of platelets.
Does this mean it will make a way for blood to flow in an artery? Or does it just get in the way?
Does it make room for healing cells? TFA says it doesn't interfere, but does it get out of the way when the body starts to heal?
Could something be added to 'nourish' the or promote more healing cells?
Does it promote healing or just act like a mega-bandage?
Don't get me wrong, I think it'd be great to throw this stuff in a first aid kit so you could just glop it on if you get a gash while out hiking or hunting. They could be the first real 'med-packs' like in them 'video games'.
This sig isn't original enough, it's time to come up with something witty...
There's a company called HemCon that makes a chitosan bandage - it's a protein gel bandage made from chitosan extracted from shrimp shells. The US Army currently uses it in Iraq & Afghanistan.
A large percentage (which I don't have the time to look up right now) of battlefield deaths are really bleeding to death, not instantaneous. To this end, soldiers carry "Quckclot", a powder that is similar to this product- similar but not the same. This seems to work faster- and would save lives on the battlefield.

Btw, the doctor's last name (Azar) means "randomness"
With this gel, I will no longer have a reason to take breaks from masturbation!

There's several different kinds of hemophilia. Besides the genetic caused ones (usually platelets will be scarce, nonfunctional or both), lack of certain elements in food intake (see vitamin K) will affect bleeding.

In the end we're all just human here and the same inside, you shouldn't be a hemophobic!
Using polymers to close up wounds isn't exactly new. Run-of-the mill superglue was commonly used during the Vietnam War to seal life-threatening wounds on the battlefield, but it was never FDA approved. Because it can be a severe irritant, you shouldn't be using superglue you buy at Home Depot unless you're bleeding to death in the middle of nowhere. You can, however, buy special medical superglues. Some of them are even over-the-counter.
Hemophilia can be caused by a lack of several proteins that take part in the clotting cascade, but the substance usually responsible is factor VIII.
Sometime in pre-history, it was noticed that many things like; dried marigold petals and spider web staunches blood. It was common practice to bleed patients at one time, and when the leech was removed, spider web was used as a poltice. I have personally used spider web on cuts, and it stops the flow in seconds. I should have applied for a research grant dang it!

I bet you could also tailor this substance to repair things like embolisms that burst, aortic disections, etc. Of course it would mean getting into surgery immediately but more people bleed out at the hospital than anywhere else.
As a potential solution to rising gun fatalities, maybe we could use it to coat bullets.

These stories are free but worth money.
According to the title the gel quickly stops bleeding, but I think it would be better if it didn't bleed in the first place.
So I think I'll wait for version 2.
Any sufficiently unpopular but cohesive argument is indistinguishable from trolling.
Be thankful it is only lovely Hepatitis-C, Bayer could have given you AIDS! Look it up, the Koate (name of the blood platelet
medication) scandal in the late 80s. After a while of selling contaminated batches of the medication world-wide they found out that it was contaminated. So what they did was of course to pasteurize some of it for sale in the US, Europe and in Japan and sell the contaminated version to the worthless people of Asia and South America that are in any event scheduled for large-scale termination. However even those that are in the more valuable population segment on this world were exposed to the AIDS virus through Bayer's Koate for quiet some time. Hope you didn't take that crap in the 80s.
But as I said, look it up. Google for Bayer, Koate and Aids.
I just modded you up btw so I can't post with my account.
Engineering is the art of compromise.
Indeed - superglue was invented to close wounds http://en.wikipedia.org/wiki/Superglue#Medicine and is still used in hospitals around the world

Yes, but have you ever squirted it into any gaping holes to see if the bleeding would stop?
She bleeds all the time! Maybe this will help with that "not so fresh feeling".

A few weeks ago, I was talking about Trauma Center for the Nintendo DS with a friend of mine. In the game, you play a doctor who operates on patients, removing tumors with your stylus, sewing them back up, etc. My friend's girlfriend is in med school currently and says that all the basic procedures are accurate enough, with the exception of one: a gel you apply to stop bleeding. I guess that's not true anymore.

All bleeding stops one way or another no matter how bad it is....
and how many people laughed when they talked about the miracle cureall antibiotic gel that stopped people bleeding?
being vague is almost as cool as doing that other thing...
How about packing helmets/vests/etc with a layer of this stuff for things that get through? I for one would prefer that the padding in a helmet be filled with this rather than plain ol' squishy gel.

You know, in that same vein! ( :( ) there is a product called Thrombin JMI, which is recombinant bovine thrombin (aka activated Factor II. It is a spray that will aid in blood clotting. But this again is for small oozy/capillary type bleeding.

I was really enjoying the article blurb going 'oh right! Awesome!' to myself until I read "paradigm shift"... Not even the best technology can overcome the power of a cliche.
Here is the original press release:

http://web.mit.edu/newsoffice/2006/hemostasis.htm
Not much new information here, but it's nice to read things that come "straight from the horse's mouth", so to speak.
Of real consequence is the main researcher's lab website:
http://web.mit.edu/lms/www/
It is chock full of interesting research on self-assembling peptides, including what substances they've been trying, and the eternally-asked question, Can I run my laptop off of spinach?(They isolated the chloroplast/photosystem of spinach, and hope to use it for photovoltaic purposes).
As far as discussion, most of the application has been suggested in the field of delicate microsurgery. Why not band-aids for the masses? Most likely due to the cost. Aside from the financial barriers in bringing an idea to mass-market, especially in the medical field, imagine trying to keep the candidate liquid substance stable for storage, to be used at a moment's notice; if it self-assembles easily, then it can "gel up" just as easily, too. This is combined with the fact that there are already several fairly effective ways to stop the typical cuts-and-scrapes of a household, from regular band-aids and gauze to liquid bandages (which quickly seals off a wound and prevents bleeding, in about the same amount of time). The real application would be in situations where regular hemostasis measures cannot be used or are undesirable. Again, this goes back to microsurgery. In most surgery, hemostasis is achieved by either tying off the bleeding vessel with suture, cauterizing the end of the vessel with a Bovey (an electrical tool used for cutting and cauterizing) or a laser, or simply clamping the vessel with a hemostat. There are other methods, but those are the most common ones in routine surgery. Clamping the vessel is not practical in confined spaces (the hemostat takes up space), cautery can't be used in all situations, and you can't always tie off the bleeder. The self-assembling gel described would be a boon in those surgical situations, another "arrow in the quiver", so to speak. The aforementioned application in patients with hemophilia is also plausible, if less certain.
Sadly, the journal that they are publishing in, Nanomedicine, is fairly brand new and not stocked by my local library yet. There have only been three issues of it so far (June 2006, August 2006, and October 2006) and the latest is not on their website yet. I would really like to read that article in full.

You know what's going to happen next - stick it in hypodermic darts and shoot them at the enemies - all they'll hear is "phttt" ... and then die of massive blood clots.
Or stick it in an insulin pen (empty out the penfill cartridge and replace the contents with this gel) and stick someone with it - great for hits on foreign dictators and other "inconveniences".
Guaranteed this will be weaponized - and then only the government and terrorists will have it.
As someone with a scarred cornea in the left eye from a childhood trauma with a blunt object, this is exciting actually. My right eye is 100% dominant and I'm lucky to have retained peripheral vision - however blurred (it's like a badly tuned television picture - no trouble detecting motion and shapes but cannot see anything sharply). I hope that one day technology will have come up to the level where they can repair the damage; I'd love to experience stereoscopic vision again before my time is up. The only bonus to monoscopic vision is that films and computer games are just that tiny bit more realistic for me.

Protein Gel Quickly Stops Bleeding
Thank god... I'm tired of all those protein gels that just keep on bleeding forever when you stab them.
Moderator hint: a comment is neither "Flamebait" nor "Troll" if it is true.
I don't know if it'd do anything for you, but whenever I incur a deep cut, I apply some DMSO as soon as I can. DMSO is known to speed wound healing, and prevent scar formation.
I once stood up from a chair into the corner of an open cabinet door. I could feel the blood pooling on my forehead, so I went to a nearby mirror. "That's going to leave a nice scar." I put some DMSO on a cotton pad (organic, because cotton crops get a lot of pesticides...) and applied it to my forehead. It burned a bit, but this was expected.
What I didn't expect was the virtual cauterization of the somewhat deep divot in my forehead. The 'hole' leaked lymphatic fluid for the next day or two, but the bleeding stopped right after the application of DMSO.
Don't know anything about how specifically DMSO stops my bleeding, (not a featured use on the literature page), but I've used on several different cuts, and it always slows the bleeding substantially.
I suggest getting the gel for occasional use. Call or visit your local natural food store, or the local horse supply store (tell them it's for your dog, as DMSO is only approved for a certain bladder condition in humans).
Learn the rules so you know how to break them properly.

Creepy!
That idea kinda reminds me of what they used to line the fuel tanks of some of the larger bombers in WW2. A rubber that when it came into contact with the fuel would swell and harden. So, if a bullet hit it, it would self seal.
Come to find out, they still do this kind and more advanced self sealing tanks.
Too bad it only works on women and results in an unwanted package nine months afterwards.

OR... you could simply shoot the guy with an old-fashioned, cheap 7.62x51mm bullet. I guarantee that if you can hit the dude with a hypodermic dart, you can hit the dude just as well with the high-velocity rifle round. It's not as nerdy, and the results are messier, but the aerodynamics will favor the bullet at any range. Also, I'm not aware of the armor-piercing qualities of a hypodermic dart, but I'm guessing it's a lot less capable of penetrating even a basic flak jacket than the supersonic rifle round.

I could probably stick you in a crowd and if you even felt it you'd assume it was a minor insect bite or something (30 gauge needles are pretty much painless for a subcutaneous injection, and I get to practice my technique 3 times a day).

Besides, you're much less likely to "get your kill" at extreme range with a rifle, and guaranteed to get it at close range with a hypo.
Actually, platelets, or thrombocytes (that's how they're more widely known down here where I live) are not cells, but cell fragments of a bigger cell called megakaryocyte. Also, they're not the topic of this article.

Yeah. The doctor, Kellam, was pissed at me because I had sent him a Fax asking for an appointment. It was about 6 lines. But about 6-8 months ago I had sent him a list of my physical ills and asked for help. That fax was 6 pages long. I thought I was "communicating" like a good patient. Of course now that the PA Amish schoolgirl killer left a 6 page letter I guess I better forget faxing any more doctors. Yeah. My doctor just wanted me to come in one visit one complaint. None of them are interested to get me back to work. Which I view to be a form of treason against taxpayers for them to artificially keep me on disability. But, that's why this here is a Twilight Zone Area. Kind of like living inside a black hole. But sometimes, sometimes I wonder how many other Virginians (& Virginia truck drivers esp.) are being treated the same way, and then I get a bit angry.
