These cells normally act as special chemoreceptors located along blood vessels, particularly in the carotid bodies (at the bifurcation of the common carotid artery in the neck) and in aortic bodies (near the aortic arch).

The phenomenon is known as river bifurcation.

What's happened since is that bifurcation I described.

That external aortic root, it will never work, you know.

So I set out to change the entire treatment for aortic dilation.

This is because aortic insufficiency causes increased blood flow in the ascending aorta.

You can see two of the leaflets of the aortic valve working there.

Bentall procedure Replacement of the damaged section of aorta and replacement of the aortic valve.

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

The aorta actually has the little arch like that. We call that the aortic arch.

In the middle, you can see that little structure squeezing out, that's the left ventricle, pushing blood out through the aortic valve.

And there's kind of a bifurcation people had to choose between fear and acceptance actually fear and indifference they kind of chose suspicion.

And then the final valve, I need to find a nice spot to write it maybe to right here, this final valve that passes through is called the Aortic valve.

If you compare our new treatment to the existing alternative, the composite aortic root graft, there are one or two startling comparisons which I'm sure will be clear to all of you.

I had to go back to the original definition of eroticism, the mystical definition, and I went through it through a bifurcation by looking, actually, at trauma, which is the other side.

Now, they're not always as well sign posted as this one, but you know those times in your life when you come to a bifurcation on the path, and you sense that the potential for change is heightened.

Radiation therapy Radiation may be used to treat stage 2 seminoma cancers, or as adjuvant (preventative) therapy in the case of stage 1 seminomas, to minimize the likelihood that tiny, non detectable tumors exist and will spread (in the inguinal and para aortic lymph nodes).

Starting with newspapers, what we saw was high cost as an initial requirement for making information, knowledge and culture, which led to a stark bifurcation between producers who had to be able to raise financial capital, just like any other industrial organization and passive consumers that could choose from a certain set of things that this industrial model could produce.
