There are many different causes of the scarring. Viruses are common. Hepatitis B, hepatitis C, what we call autoimmune diseases where the body attacks the liver itself such as primary biliary cirrhosis is an autoimmune disease; sclerosing cholangitis is an autoimmune disease; and so those diseases where the liver is being destroyed by either the virus or an autoimmune disease, it can only scar, and why it doesn't regenerate has to do with the fact that there is this ongoing scar tissue that blocks that regeneration.
John RobertsWe cannot deny that our decision today will have an impact on the ability of law enforcement to combat crime. Cell phones have become important tools in facilitating coordination and communication among members of criminal enterprises, and can provide valuable incriminating information about dangerous criminals. Privacy comes at a cost.
John RobertsWhen a liver becomes cirrhotic, those are the common complications. We see that the patients have bleeding from their stomach and intestines. They have abdomens that become full of fluid. Their ankles swell with the same type of fluid, and they also can become confused and not themselves. Those are kind of the main things that we see when people get end-stage liver disease and have cirrhosis.
John RobertsPretty much everybody knows there are not enough organs for all of those patients who need to get transplants, and what happens is, is that organs are actually directed in liver transplantation to those patients who are the sickest. So the patients who have the greatest chance of dying in the next three months or so are the ones who get the priority for the liver transplant.
John RobertsWhen we think about living donor transplant, what we're banking on is the ability of the liver to regenerate itself. Now, it's not the same sort of regeneration we think about with the starfish where we cut off the arm and it grows a new arm. With the liver, what happens is the remaining liver gets bigger, and your body knows the size of the liver that it needs, and when it recognizes that there is not enough liver, it sends nutrients and signals to the liver and says "get bigger."
