#Freedom Driver allows man with artificial heart to await transplant at home Heart failure patients awaiting organ transplants normally find themselves anchored to the hospital bed by a washing machine-sized device that keeps blood pumping through their veins.

#Lung'filtering'technique can reduce transplant rejection University of Manchester researchers have used a new technique to recondition poorly functioning lungs

and remove donor white blood cells in an attempt to increase the number of lungs available for transplant,

This can repair an organ that would normally be turned down for transplant. Given that 80%of donor lungs are used currently not

Dr James Fildes, from the University's Collaborative Centre for Inflammation Research and the Transplant Centre at the University Hospital of South Manchester NHS Foundation Trust, led the study.

#Researchers get under the skin to develop new transplant technique James Shapiro, one of the world leading experts in emerging treatments of diabetes, can help

and worldwideould be alleviated through the availability of suitable animal organs for transplant. Pigs in particular have been especially promising candidates due to their similar size and physiology to humans.

But the transplant of whole, functional organs composed of living cells and tissue has presented a unique set of challenges for scientists.

Some researchers agree with Rothblatt that the latest results mean pig-to-human transplants are plausible. think it possible;

In fact, thousands of people die each year while waiting on transplant lists. Donated human organs are scarce,

leading transplant surgeons have been meeting with Revivicor ever few months to plan what genes they like to see added next.

a transplant surgeon and researcher at the National Heart, Lung, and Blood Institute, in Bethesda, Maryland, says a heart from one of Revivicor pigs lasted two and a half years inside a baboon.

The heart transplants were not life-sustaining but eterotopic? the pig heart was attached to the baboon circulatory system

when a transplant into humans could occur. That is because surgeons still need to completely replace a baboon heart with one from these pigs

Lung transplants will be harder, since lungs are permeated with blood vessels and heavily exposed to the immune system.

So far, transplants last only a matter of days, says Rothblatt. She has been financing research at the University of Maryland,

heart transplants only come from brain dead donors whose hearts are cut away while their bodies are still healthy.

This novel, noninvasive and rapid test successfully predicted which livers would function properly in transplant patients,

A liver transplant may involve the whole liver, a reduced liver, or a liver segment.

Most transplants involve the whole organ, but transplants using segments of the liver have been performed with increasing frequency in recent years.

This would allow two liver recipients to be transplanted from one donor or to allow for living donor liver donation.

Currently, about 17,000 adults and children have been approved medically for liver transplants and are donated waiting for livers to become available,

#Novel method to predict postoperative liver cancer recurrence in transplant patients UCLA transplantation researchers have developed a novel method that more accurately calculates the risk of disease recurrence in liver cancer patients who have undergone a liver transplant,

Chair in Surgery and director of the Pfleger Liver Institute and Dumont-UCLA Transplant and Liver Cancer Centers presented the study during the annual meeting of the Southern Surgical Association.

The retrospective study included 865 liver cancer patients who had transplants between 1984 and 2013 said study first author Dr. Vatche G. Agopian an assistant professor of surgery in the division

The three groups of factors that comprise the UCLA nomogram include pre-transplant radiologic information

or the number and size of tumors on MRI and CT SCANS three pre-transplant blood biomarkers thought to be predictive for cancer recurrence

or aggressiveness of the tumor and whether the cancer has invaded the liver's blood vessels factors that can't be determined before transplant.

For example a patient with a 5 centimeter tumor who would have qualified for liver transplant under the Milan criteria might in fact have a very aggressive tumor that is likely to recur after transplant

The Milan criteria presented a major step in improving the outcomes of liver cancer patients undergoing transplant Agopian said.

In the largest single-institution experience with liver transplant for liver cancer excellent long-term survival was achieved.

Incorporation of routine pre-transplant biomarkers to existing radiographic size criteria significantly improves the ability to predict post-transplant recurrence
