Joe Landolina: This gel can make you stop bleeding instantly

Prevodilac: Nebojsa Kracun Lektor: Mile Živković

I want you guys to imagine that you're a soldier

Želim da zamislite da ste vojnik

running through the battlefield.

koji trči preko bojnog polja.

Now, you're shot in the leg with a bullet,

Sada, metak vas pogađa u nogu,

which severs your femoral artery.

i prekida vašu butnu arteriju.

Now, this bleed is extremely traumatic

Sada, ovo krvarenje je ekstremno traumatično

and can kill you in less than three minutes.

i može vas ubiti za manje od tri minuta.

Unfortunately, by the time that a medic

Nažalost, dok bolničar

actually gets to you,

stigne do vas,

what the medic has on his or her belt

ono što bolničar ima na svom pojasu

can take five minutes or more,

može trajati pet minuta i duže,

with the application of pressure, to stop that type of bleed.

sa apliciranjem pritiska, da bi se zaustavilo krvarenje.

Now, this problem is not only a huge problem

Sada, ovaj problem nije samo ogroman problem

for the military, but it's also a huge problem

za vojsku, već i ogroman problem

that's epidemic throughout the entire medical field,

koji je poput epidemije na celokupnom medicinskom polju,

which is how do we actually look at wounds

a to je kako mi gledamo na rane

and how do we stop them quickly

i kako ih zaustavljamo brzo,

in a way that can work with the body?

a da to ide u skladu sa telom?

So now, what I've been working on for the last four years

Sada, ono na čemu sam radio poslednje četiri godine

is to develop smart biomaterials,

je razvijanje pametnih biomaterijala,

which are actually materials that will work

koji su u stvari materijali koji rade

with the body, helping it to heal

u skladu sa telom, pomažući mu da se zaleči

and helping it to allow the wounds to heal normally.

i pomažući mu da dozvoli ranama da se zacele normalno.

So now, before we do this, we have to take a much closer look

Sada, pre nego što to uradimo, mi ćemo pogledati izbliza

at actually how does the body work.

kako telo u stvari radi.

So now, everybody here knows

Sad, svi ovde znaju

that the body is made up of cells.

da je telo napravljeno od ćelija.

So the cell is the most basic unit of life.

Dakle, ćelija je osnovna jedinica života.

But not many people know what else.

Ali malo ljudi zna šta još.

But it actually turns out that your cells

Ali u stvari se ispostavlja da vaše ćelije

sit in this mesh of complicated fibers,

sede u mreži komplikovanih vlakana,

proteins and sugars

proteina i šećera

known as the extracellular matrix.

poznatih kao vanćelijska matrica.

So now, the ECM

Sada, VĆM

is actually this mesh that holds the cells in place,

je u stvari ova mreža koja drži ćelije na mestu,

provides structure for your tissues,

kreira strukturu za vaša tkiva,

but it also gives the cells a home.

ali takođe daje ćelijama dom.

It allows them to feel what they're doing,

Dozvoljava im da osete šta rade,

where they are, and tells them

gde su i kaže im

how to act and how to behave.

kako da deluju i kako da se ponašaju.

And it actually turns out that the extracellular matrix

I ispada na kraju da je ta vanćelijska matrica

is different from every single part of the body.

drugačija u svakom delu tela.

So the ECM in my skin

Dakle, VĆM u mojoj koži

is different than the ECM in my liver,

je drugačiji od VĆM-a u mojoj jetri,

and the ECM in different parts of the same organ

i VĆM u različitim delovima istog organa

actually vary, so it's very difficult

može da varira, pa je veoma teško

to be able to have a product

imati proizvod

that will react to the local extracellular matrix,

koji reaguje na lokalnu vanćelijsku matricu,

which is exactly what we're trying to do.

što je baš ono što pokušavamo da uradimo.

So now, for example, think of the rainforest.

Sad, na primer, mislite na kišnu šumu.

You have the canopy, you have the understory,

Imate krov prašume, imate krošnje,

and you have the forest floor.

i imate šumsko tlo.

Now, all of these parts of the forest

Sad, svi ovi delovi šume

are made up of different plants,

su sastavljeni od različitih biljaka,

and different animals call them home.

i različitih životinja koje žive u njima.

So just like that, the extracellular matrix

Baš tako, vanćelijska matrica

is incredibly diverse in three dimensions.

je neverovatno raznovrsna u tri dimenzije.

On top of that, the extracellular matrix

Povrh toga, vanćelijska matrica

is responsible for all wound healing,

je odgovorna za zarastanje svih rana,

so if you imagine cutting the body,

pa ako zamislite sečenje tela,

you actually have to rebuild

morate u stvari da ponovo izgradite

this very complex ECM

ovu veoma kompleksnu VĆM

in order to get it to form again,

da bi se ponovo formirala,

and a scar, in fact, is actually

a ožiljak je, u stvari

poorly formed extracellular matrix.

loše formirana vanćelijska matrica.

So now, behind me is an animation

Sada, iza mene je animacija

of the extracellular matrix.

vanćelijske matrice.

So as you see, your cells sit in this complicated mesh

Kao što vidite, ćelije sede u ovoj komplikovanoj mreži

and as you move throughout the tissue,

i dok se krećete kroz tkivo,

the extracellular matrix changes.

vanćelijska matrica se menja.

So now every other piece of technology on the market

Tako da sada svaki drugi komad tehnologije na tržištu

can only manage a two- dimensional approximation

može da upravlja sa dvodimenzionalnom aproksimacijom

of the extracellular matrix,

vanćelijske matrice,

which means that it doesn't fit in

što znači da se ne uklapa

with the tissue itself.

sa samim tkivom.

So when I was a freshman at NYU,

Kada sam bio brucoš na NYU,

what I discovered was you could actually take

otkrio sam da možete uzeti

small pieces of plant-derived polymers

male delove biljnog polimera

and reassemble them onto the wound.

i da ga ugradite u ranu.

So if you have a bleeding wound like the one behind me,

Tako da ukoliko imate krvarenje kao što je ovo iza mene,

you can actually put our material onto this,

možete staviti naš materijal na ovo,

and just like Lego blocks,

i baš kao Lego kockice,

it'll reassemble into the local tissue.

on će ponovo izgraditi lokalno tkivo.

So that means if you put it onto liver,

To znači da ako ga stavite na jetru,

it turns into something that looks like liver,

pretvara se u nešto što je kao jetra,

and if you put it onto skin,

a ako ga stavite na kožu,

it turns into something that looks just like skin.

pretvoriće se u nešto što je kao koža.

So when you put the gel on,

Kada stavite gel,

it actually reassembles into this local tissue.

on se ugradi u lokalno tkivo.

So now, this has a whole bunch of applications,

Ovde ima gomila mogućnosti za primenu,

but basically the idea is, wherever you put this product,

ali osnovna ideja je, gde god stavite ovaj proizvod,

you're able to reassemble into it immediately.

u mogućnosti ste da odmah izgradite to.

Now, this is a simulated arterial bleed —

Ovo je simulirano arterijsko krvarenje -

blood warning —

upozoravam na krv -

at twice human artery pressure.

sa duplim pritiskom.

So now, this type of bleed is incredibly traumatic,

ovo je vrsta krvarenja koja je traumaticna,

and like I said before, would actually take

i kao što sam rekao pre, bilo bi potrebno

five minutes or more with pressure

pet minuta ili duže sa pritiskom

to be able to stop.

da bi se zaustavilo.

Now, in the time that it takes me to introduce the bleed itself,

Za vreme koje je potrebno da bih se je sa upoznao sa krvarenjem,

our material is able to stop that bleed,

naš materijal može da ga zaustavi,

and it's because it actually goes on and works

jer on u stvari počne i radi

with the body to heal,

zajedno sa telom na izlečenju,

so it reassembles into this piece of meat,

tako da se stopi sa ovim parčetom mesa,

and then the blood actually recognizes

i krv prepozna

that that's happening, and produces fibrin,

da se to dešava i počne da stvara fibrin,

producing a very fast clot in less than 10 seconds.

stvarajući ugrušak za manje od 10 sekundi.

So now this technology — Thank you.

Ova tehnologija - hvala.

(Applause)

(Aplauz)

So now this technology, by January, will be in the hands of veterinarians,

Ova tehnologija, do januara, će biti u rukama veterinara,

and we're working very diligently to try to get it into the hands of doctors,

i mi radimo veoma marljivo da je donesemo do ruku doktora,

hopefully within the next year.

uz malo sreće, tokom sledeće godine.

But really, once again, I want you guys to imagine

Opet, želim da zamislite

that you are a soldier running through a battlefield.

da ste vojnik koji trči kroz bojno polje.

Now, you get hit in the leg with a bullet,

Pogođeni ste metkom u nogu,

and instead of bleeding out in three minutes,

i umesto da iskrvarite za tri minuta,

you pull a small pack of gel out of your belt,

vi izvadite bočicu gela iz svog opasača,

and with the press of a button,

i pritiskom na dugme,

you're able to stop your own bleed

zaustavljate krvarenje

and you're on your way to recovery.

i na putu ste ka ozdravljenju.

Thank you very much.

Hvala vam mnogo.

(Applause)
