And the formation of these plaques that obstruct the actual blood vessel, that actually obstruct the artery.

This is actually an engineered blood vessel.

Hopefully I'm not confusing too much these medical terms confuse ME a lot but I want to make it very clear, thrombosis is formation of a blood clot inside of a blood vessel than can restrict the flow of blood.

Sometimes it can even completely obstruct the blood vessel.

So we actually perfuse first the blood vessel tree with the patient's own blood vessel cells, and we then infiltrate the parenchyma with the liver cells.

So thrombi are these blood clots that form, that can help to obstruct a blood vessel.

Let's say that this is a blood vessel in the brain.

A blood vessel exploded in the left half of my brain.

A blood vessel is made up of two different cell types.

You place the vascular blood vessel lining cells on the inside.

However, as the diameter of the blood vessel decreases further, the red blood cells have to squeeze through the vessel and often can only pass in single file.

My father'd burst a blood vessel if he heard you say that.

I'm actually trying to draw the same blood vessel where it actually breaks.

As this happens, it starts to really really really obstruct the blood vessel.

And what we do is we, to make a blood vessel, same strategy.

And this is an X ray showing you the patent, functional blood vessel.

Now, once the blood vessel is narrowed, that restricts the blood supply so you aren't able to get as much blood through it, so the blood supply is restricted.

let's assume that he is working with my blood vessel and my blood pressure is about 115 systolic over 75 diastolic.

large organ, vascular, a lot of blood vessel supply, a lot of cells present.

So an ischemic stroke is actually very, very similar to what we saw in a heart attack, except it's not occurring in a coronary blood vessel, it's occurring in a blood vessel in the brain.

And we then can re perfuse the liver with cells, preserving the blood vessel tree.

So what we've next done is we've moved on to looking at blood vessel dilatation.

This actual clot that forms, that can restrict the blood vessel, this is a thrombus.

And in fact, every cell in our body has a little blood vessel that's near by.

You see, last spring I had a slight a tiny convulsion of a tiny blood vessel.

Whenever someone talks about an embolus, or emboli, or embolism, they're talking about something moving through the blood that eventually blocks a blood vessel.

A hemorrhagic stroke to hemorrhage means to bleed, it's literally just a fancy word for bleeding and so in a hemorrhagic stroke you have a situation where a blood vessel can actually break, where you have a blood vessel

We'll talk more in the future of why a blood vessel might break strongly related to high blood pressure and other risk factors, but I don't want to get into that right now but you could imagine if a blood vessel breaks, you have all this blood spewing into the brain in, kind of, an uncontrolled way.

Anti angiogenesis drugs only target one factor, so the other factors continue to stimulate blood vessel growth.

We then take this vascular structure and we can prove that we retain the blood vessel supply.

So we put silence because there is no blood flowing at this point, because the vessel is collapsed.

He was thinking about blood vessels, and he was trying to figure How to use the stethoscope to (let's just draw the skin here over the blood vessel)

So this is more challenging large organ, vascular, a lot of blood vessel supply, a lot of cells present.

So this thrombus right here is going to make it harder for the blood to flow through this vessel.

He actually devised some of the same technologies used today for suturing blood vessels, and some of the blood vessel grafts we use today were actually designed by Alexis.

Pathophysiology The kidney failure in hepatorenal syndrome is believed to arise from abnormalities in blood vessel tone in the kidneys.

So, even though there's a blood vessel near by, really, no flow is happening, so I'll just write no flow .

It mainly affects the aorta (the main blood vessel leaving the heart) and its branches, as well as the pulmonary arteries.

We then take the cells, the vascular cells, blood vessel cells, we perfuse the vascular tree with the patient's own cells.

This required developing a bioassay that would enable us to observe the inhibition of blood vessel growth in the presence of tumors.

Rebecca has a benign blood vessel tumor that's growing out through her skull, has obliterated her nose, and she's having difficulty seeing.

I had a similar experience when I was working in his lab, trying to isolate the first inhibitors of blood vessel growth (which were large molecular weight substances). This required developing a bioassay that would enable us to observe the inhibition of blood vessel growth in the presence of tumors.

When the diameter of the blood vessel is just slightly larger than the diameter of the red blood cell the Fahraeus Lindquist effect occurs and there is a decrease in wall shear stress.

For acute exposures of whole bone marrow, the threshold dose for clinically significant depression of blood formation is about 0.5 Gy.
