Fighting Heart Disease with Nanoburrs


For heart disease patients with damaged arteries, doctors typically use stents to open blocked blood vessels, but the treatment requires surgery, and not all damaged areas are well suited to stents. Watch this videocast to find out about new research to develop "nanoburrs" that find damaged tissue and deliver medicine to it, broadening the possibilities for non-invasive treatment.

Now from the Boston Museum of Science, Sci-tech today, on NECN.

We are talking about a breakthrough in the battle against heart disease. Harvard and MIT scientists have developed a new technology that requires no surgery: it’s called Nanoburrs. And Dr. Brindha Muniappan joins us live from the Museum of Science in Boston and tells us about it.
Thanks for being here.

Thanks Beth. It’s nice to be here.

So explain to us a little bit about what a Nanoburr is?

Sure. So a nanoburr is a nanoparticle. So very very tiny particle we can’t see with our naked eyes on such a small scale. But these particles have been designed to sort of be like burrs you might find out in nature. So if you are out on a walk for example, maybe you’ve already encountered some of these burrs stuck to your socks or maybe to your pet. These nanoparticles were designed just like these burrs to stick but to a specific place in our body to damaged heart vessels.

And how are they able to do that?

Well, the team of researchers that you mentioned earlier designed the nanoparticles to have a very special protein coding the outside of them. And that protein really just wants to bind to another protein that’s only exposed when heart vessels are damaged.
And so, I have got a little demonstration here. If you imagine that this tube is like a blood vessel, the clear area is a normal tissue and the white area is a site of damage. We would inject the nanoburr and it will bind only to the site of damage. You can do that with multiple nanoburrs. There they stick only to the site of damage. And that’s the high technology here.

So once the nanoburr attaches to that tissue, how does it help improve the condition of the heart?

Well, the inside of the nanoburr contains medicine. So once the burr is bond to the site of damage, it can very slowly release medicine to treat the site of damage. And that’s another improvement of this particular technology: the ability to very slowly release the medicine over 12-14 days.

So how is this improvement over conventional treatments for blocked or damaged arteries?

Well, in one way, as I mentioned, there is a slow release of drug. But also, these nanoburrs don’t have to be surgically implanted, they can
just be injected. And there is a little bit more of an advantage, there is a possibility of using this technology for treating other diseases, including cancer or severe inflammation.

So a team of scientists at Harvard and MIT developed the technology. Where is it and it’s availability to patients?

Well, this technology unfortunately is still in very early stages. Scientists have done some initial tests in rats in their laboratory.They are hoping to do a bit more tests in animals. Maybe within about five years, they might be able to do some small clinical tests in human patients.

So it sounds like the idea of this isn’t just to treat a heart that has already undergone something like a heart attack but more to prevent it from happening?

Well, it certainly might be used before a heart attack, but it could also be used in conjunction with current treatments like stents that are currently used to keep open a previously blocked artery. So it’s possible that there are multiple uses for this technology.

Alright, Dr. Brindha Muniappan, thanks so much for joining us.
Thank you, Beth.

But these particles have been designed to sort of be like visual you might find out in nature.

These natal particles were designed just like those burrs to stick but to a specific place in our body to damaged heart vessels.

Well, the team of researchers that imagined earlier design a nano particle to have a very special protein coating the outside of it and that protein really just wants to bind to another protein that's only expose when heart vessels are damaged. So a little demonstration here. If you imagine this tube is like a blood vessel. The clear area is a normal tissue and this white area is site of damage. We would inject the nanoburr and it would bind only to the site of damage. You can do that with multiple nanoburrs. There they stick only to the site of damage and that's the high technology here.

So once the nanoburr attaches to that tissue, how does that help improve the condition of the heart?

Well, the inside of the nanoburr contains  medicine, so once the burr is bind to the site of damage, it can very slowly release medicine to treat the site of damage. That's another improvement of this particular technology, the ability to very slowly release the medine over 12-14 days.

So how is this improvement over conventional treatments for blocked damaged /?

Well in one way that we... In one way as I mention there is a slow release of drug but also these nanoburrs don't have to be surgically implanted, they can just be injected. And there is a little bit more of advantage. There is possibility of using this technology for treating other diseases sort of, including cancer or severe imflammation.

So a team of scientists at Havard and MIT develop the technolgy. Where is it and it's availability to patients?

Well this technology unfortunately is still in very early stages. Scientists have done some initial tests in rats and their laboratory. They're hoping to do a bit more testing in animals. And maybe within about 5 years, it might be able to do some small clinical tests in human patients.

So it sounds like the idea of this isn't just to treat a heart that has already  undergone something like a heartattack but more to prevent it from happening?

Well it's certainly might be used before a heartattack, but it can also be used in conjunction with current treatments like stents that are currently used to keep open a previously block artery. So it's possible that there are multiple uses for this technology.

Now from the Boston Museum of Science, Sci-tech today on NECN.

We are talking about a breakthrough in the battle against heart disease. Harvard and MIT scientists have developed a new technology that requires no surgery: it’s called “nanoburrs”. And Dr. Brandon Monyoben joins us live from the Museum of Science in Boston and tells us about it. Thanks for being here.
Thanks Beth. It’s nice to be here.
So explain to us a little bit about what a “nanoburr” is?
Sure. So a “nanoburr” is a nano particle. So very, very tiny particle we can’t see with our naked eyes on such a small scale. But these particles have been designed to, sort of be like burrs you might find in the nature. So, if you are out on a walk, for example, maybe you’ve already encountered some of these burrs stuck to your socks or maybe to your pet. These nano particles were designed just like these burrs to stick but to a specific place of our body to damaged heart vessels.
And how were they able to do that?
Well, the team of researchers that you mentioned earlier designed the nano particles to have a very special protein colding the outside of them. And that protein really just wants to bind to another protein that’s only exposed when heart vessels are damaged. And so, I’ve got a little demonstration here. If you imagine this tube is like a blood vessel, the clear area is a normal tissue and this white area is a site of damage. We would inject the “nanoburr” and it would bind only to the site of damage. You can do that with multiple “nanoburrs”. There they stay only to the site of damage. And that’s the high technology here.
So once the “nanoburr” attaches to that tissue, how does it help improve the condition of the heart?
Well, the inside of the “nanoburr” contains medicine. So once the burr is bond to the site of damage, it can very slowly release medicine to treat the site of damage. And that’s another improvement of this particular technology: the ability to very slowly that release the medicine over 12-14 days.
So how is this improvement over conventional treatments for blocked damaged arteries?
Well, in one way, as I mentioned, there’s a slow release of drug. But also, these “nanoburrs” don’t have to be surgically implanted, they can just be injected. And there’s a little bit more of advantage, there’s the possibility of using this technology for treating other diseases, so, uh…including cancer or severe inflammation.
So team of scientists at Harvard and MIT developed the technology. Where is it? And it’s availability to patients.
Well, this technology unfortunately is still in very early stages. Scientists have done some initial tests in rats in their laboratory. They are hoping to do a bit more tests on animals. Maybe within about five years, they might be able to do some small clinical tests in human patients.
So it sounds like the idea of this isn’t just to treat a heart that has already undergone something like a heart attack but more to prevent it from happening?
Well, it certainly might be used before a heart attack, but it could also be used in conjunction with current treatments like stents that are currently used to keep open a previously blocked artery. So it’s possible there are multiple uses for this technology.
Alright, Dr. Brandon Monyoben, thank you so much for joining us.
Thank you, Beth.

We are talking about a breakthrough in the battle against heart disease. Harvard and MIT scientist developed a new technology that required no surgery is called Nanoburrs. And doctor Brandan Moneyobet join us as life in museum of scientist Boston tells us about it. Thanks for being here.

Thanks. That’s nice to be here.

So explain to us a little bit about what Nanoburrs is?

Sure. A Nanoburr is a nano partical, so very, very tiny partical we can’t see with our naked eyes, such a small skill. But this particals are being designed to sort of like burrs you can find in nature. So you are out on our work, for example, you are encounter somebody’s work is stunk to your shock, or maybe to your pet. This nano partials were design just like those birth to stick, but to a specific place in our body to damage heart vessles.

And how would they able to do that?

Teem researcher image earlier to design nano partical to have a very special protein codling the outside of them. And that protein, really just want to bite to another protein that only expose when heart battles are damage. So I get a little demonstration here. If you image this tube is like a blood vessel, the clear area is a normal tissue, and this white area is a sight of damage. we would ingest the Nanoburr and it would bite only to the sight of damage. You can do that with Nanoburr. There they stick only to the sight of damage. And that’s the high-technology here.

So what the Nanoburr attach to that tissue? How does it improve the condition of the heart?

Well, the inside of the Nanoburr contains medicine. So once the bur is bound to the sight of the damage, they can very slowly release the medicine to treat the sight of damage. That’s another improvement of this particular technology. The ability to very slowly to bless the medicine over 12 to 14 days.

So how is that improvement over conventional treatment for block damage documentaries?  

Well, in one way, image that’s a slow release drug, but also this Nanoburrs don’t have to be surgery implanted, just be injected. And that’s a little bit more advantage. That’s a possibility of using this technology for treating other diseases, including cancer or sever inflammation.

So teem of scientists in Harvard MIT developed the technology where is it, is availability to patient.

Well, this technology, unfortunately, is still in early stage. Scientists have done some initial test in rats in the laboratory. They are hoping to a bit more texting in animals. Maybe about within 5 years, they might be able to do some small critical text in human patient.

So sounds like the idea of this isn’t just to treat a heart that is already undergone, something like heart attack, but more to prevent for happening.

Its certainty might be use before a heart attack. it can also be use in conjunction with currently men like stence that currently use to keep open that previously block artery. So it’s possible that there are multible uses for this new technology.

All right, Doctor Mentory. Thanks for joining us.

Thank you then.

We are talking about a breakthrough in the battle against heart disease. Harvard and MIT scientists have developed a new technology that requires no surgery. It's called "nanoburrs". And Dr. Brindha Muniappan joins us live(现场连线) from the Museum of Science in Boston and tells us about it. Thanks for being here!
Thanks best! It's nice to be here!

1.
So explain to us a little bit about what a nanoburr is.

Sure. So a nanoburr(纳米毛刺) is a nano particle(纳米粒子), so very very tiny particle we can't see with our naked eyes such small scale. But these particles have been designed to sort of be like burrs you might find out in nature. So if you are out on a walk for example maybe you are encountered some of these burrs stuck to your socks or maybe to your pet. These natal(出生的,诞生的) particles were designed just like those burrs to stick but to a specific place in our body to damaged heart vessels.

2.
And how are they able to do that?

Well, the team of researchers that imagined earlier design a nano particle to have a very special protein coating the outside of it and that protein really just wants to bind to another protein that's only expose when heart vessels are damaged. So a little demonstration(示范) here. If you imagine this tube is like a blood vessel. The clear area is a normal tissue and this white area is site of damage. We would inject the nanoburr and it would bind only to the site of damage. You can do that with multiple nanoburrs. There they stick only to the site of damage and that's the high technology here(这就是技术的关键所在).

3.
So once the nanoburr attaches to that tissue, how does that help improve the condition of the heart?

Well, the inside of the nanoburr contains
medicine, so once the burr is bind to the site of damage, it can very slowly release medicine to treat the site of damage. That's another improvement of this particular technology, the ability to very slowly release the medicine over 12-14 days.


4.
So how is this improvement over conventional treatments for blocked damaged arteries(动脉)?

Well in one way that we... In one way as I mention there is a slow release of drug but also Butalso, these nanoburrs don’t have to be surgically implanted, they can just be injected. And there is little bit more of an advantage. There is possibility of using this technology for treating other diseases sort of, including cancer or severe inflammation(发炎,发烧,炎症).

5.
So a team of scientists at Harvard and MIT developed the technology. Where is it and it's availability to patients?

Well this technology unfortunately is still in very early stages. Scientists have done some initial tests in rats and their laboratory. They're hoping to do a bit more testing in animals. And maybe within about 5 years, it might be able to do some small clinical tests in human patients.

6.
So it sounds like the idea of this isn't just to treat a heart that has already
undergone something like a heart attack but more to prevent it from happening?

Well it's certainly might be used before a heart attack, but it can also be used in conjunction with(与……连同在一起) current treatments like stents that are currently used to keep open a previously blocked artery. So it's possible that there are multiple uses for this technology.

All right. Dr. Brindha Muniappan, thanks so much for joining us!

Now, for the Boston Museum of Science, Sci-tech today on NECN.

We’re talking about the breakthrough in the battle against heart disease. Harvard and MIT scientists have developed a new technology that requires no surgery. And it’s called Nanoburrs. And Doctor Brindha Muniappan joins us live from the Museum of Science in Boston, tells us about that. Thank you for being here.

Thanks, Betty, nice to be here.

Sure, so a Nanoburr is a nano particle, so very tiny particles, we can’t see with our naked eyes in such small skill. But these particles have been designed, sort of, be like burrs you may find out in nature. If you’re out on a walk for example, maybe you've already encountered some of these burrs stuck to your socks, oh, maybe to your pets, these nano particles for design just like these burrs, to stick, but to a specific place of body to damage heart vessels.

And how are they able to do that?

Well, the team researchers that you mentioned earlier, designed the nano particles to have very special protein coating the outside of them. And that protein really just wants to bind to another protein that’s only exposed when heart vessels are damaged. So I have got a little demonstration here. If you imagine these tubes is like, a blood vessel, the clear area is normal tissue and this white area is side of damage. We would inject the Nanoburr and it would bind only to the side of damage. You can do that with mutable Nanoburrs there, they stick only to the side of damage. And that’s the high technology here.

So once the Nanoburr attached to that tissue. How does that help improve the condition of the heart?

Well, the inside of Nanoburr contains medicine. So once the burr is bound to the side of damage, it can very slowly release medicine to treat the side of damage. That’s another improvement of this particular technology, the ability to very slowly release the medicine over, uh 12 to 14 days.

So how is this improvement over the conventional treatment for blocked damaged arteries?

Well, in one way, as I mentioned, there is a slow release of drug, but also these Nanoburrs don’t have to be surgically implanted, they can just be injected. And there is a little bit more of advantage. There is a possibility of using this technology for treating other diseases, so, including cancer, or severe inflammation.

So team scientists at Harvard and MIT developed technology, where is it in its availability to patients?

Well, this technology, unfortunately, is still in very early stages scientists have done some initial tests in rats in their libratory. They are hoping to do a bit more testing in animals and maybe within about 5 years, they might be able to do some small clinical tests in human patients.

So it sounds like the idea of this, is just to treat a heart that has already undergone something like heart attack but more to prevent it from happening?

Well, it certainly might be used before a heart attack, but it can also be used in conjunction with current treatments like stents that are currently used to keep open a previously blocked artery. So it’s possible that there are mutable users for this technology.

All right. Doctor Brindha Muniappan . Thank you for joining us.

HOMEWORK

We’re talking about a break-through in a battle against heart disease, Hartford and MIT scientists have developed a new technology that requires no surgery, it’s called nanoburrs. And Doc. Brandent Mony? joins us live from the museum of Science-Boston, tells about it. Thanks for being here.
Thanks, Bette, it’s nice to be here.
So explain to us a little bit about what the nanoburr is.
Sure. So a nanoburr is a nano particle. So very tiny particle, we can’t see it with our naked eyes, and such small skill. But this particle had been designed ~~so of be like burrs you might find out in nature, so if you’re out on a walk, for example, maybe you’re already in counter some of these burrs stacked to your socks, or maybe to your pet, these nanoparticles were designed just like those burrs to stick but to a specific place in our body to damage heart vessels.
And how are they able to do that?
Well, the team of the researchers in mention earlier designed the nano particles to have a very special protein coating the outside of them, and that protein really just wants to bind to the another protein that’s only exposed when heart vessels are damaged. And So I’ve got a little demonstration here, if you imaging that this tube is like a blood vessel, the clear area is normal tissue, and this white area is side of damage. We would inject the nanoburr, and it would bind only to the side of damage, you can do that with mutable nanoburrs, there they stick only to side of damaging. And that’s the high-technology here.
So once the nanoburrs are attached to that tissue, how is it help to improve the condition of the heart?

So how is that some of improvement over conventioner treatments for block a damage arteries?
Well, in one way, that we, urn~~ in one way, as I mentioned there’s slow release of drugs, but also these nanoburrs don’t have to be surgically implanted, so they can just be injected. And there’s a little more advantage, there’s a possibility of using this technology for treating other diseases, so, err~ including cancer, or severer inflammation.

Well, this technology, unfortunately, is still in very early stages of science have done some initial tests in rats in their libratory, they’re hoping to do a bit more tests in animals, maybe within about 5 years, they might be able to do some small clinical tests in human patients.
So sound like the idea of this technology is just to treat a heart that has already under gone, something like a heart attack, but more to prevent it from happening.
Well, it certainly might be used before a heart attack, but it could also be used in conjunction with current treatments, like stains that currently used to keep open up previously block surgery?, so it’s possible there’re mutable uses of this technology.
All right.  Doc. Mony?, thanks so much for joining us.
