This is called a cycle valve tube.

And this is how you make a valve.

This is actually a heart valve, which we engineered.

Does the color of the valve matter? What matters here?

Now that's a left ventricle pushing blood up through the aortic valve you can see two of the leaflets of the aortic valve working there up into the ascending aorta.

And the way you engineer this heart valve is the same strategy.

This is actually a heart valve that we've engineered, and you can see here, we have the structure of the heart valve and we've seeded that with cells, and then we exercise it.

It has a funny trilobal shape at the bottom, which contains the aortic valve.

The surgery on offer was pretty gruesome anesthetize you, open your chest, put you on an artificial heart and lung machine, drop your body temperature to about 18 centigrade, stop your heart, cut the aorta out, replace it with a plastic valve and a plastic aorta, and, most importantly, commit you to a lifetime of anticoagulation therapy, normally warfarin.

Their instructions just walk normally.

Normally it's at the back.

Even trips to the dentist require that you take antibiotics, in case you get an internal infection on the valve.

People bring their own cooker, he attaches a valve and a steam pipe, and now he gives you espresso coffee.

So that's what I normally do.

SS I normally talk about language.

My sculptures are normally very simplified.

We take the scaffold, we seed it with cells, and you can now see here, the valve leaflets opening and closing.

The process was conducted in a closed group, behind closed doors.

Normally we think about technology as interactive.

This is the time he normally arrives.

Its unique cool flow valve can efficiently discharge hot and damp exhaled breath from inside the respirator, allowing easier breathing for users.

Likewise, if you have the artificial valve option, you're committed to antibiotic therapy whenever you have any intrusive medical treatment at all.

The assessment of the value shall normally be based on reliable statistical evidence on the prices normally paid for comparable pieces of land.

Leave Closed

Normally police officers don't want to do prison.

So they don't normally let you do that.

The Commission meets biennially, normally at its headquarters.

So, the most beautiful thing I found at least what I think is the most beautiful in the book, is this heart valve.

So this is actually a Dutch company, so I called them up, and I asked, Can I borrow a heart valve from you?

Great and then I didn't hear from them for weeks, so I called, and I asked, What's going on with the heart valve?

They're closed today.

closed around them

He turned the wrong valve when he filled his cylinder he had 80 percent oxygen in his tank when he should have had 40.

The low tech bit is that it's literally a pig's heart valve mounted in the high tech bit, which is a memory metal casing.

Normally, you have to pay people to do this.

So, normally, I never do any research at all.

Normally the testes should make testosterone, the male hormone.

Now, we normally think of Tibet as a highland.

These are zebra fish. They're normally black and silver.

The Committee shall normally hold two regular sessions annually.

So you see the leaflets opening and closing of this heart valve that's currently being used experimentally to try to get it to further studies.
