06 April 2016 Current Affairs GK: Researchers at the National Heart, Lung and Blood Institute (NHLBI) in Bethesda, Maryland, have managed to keep a pig heart beating for 945 days inside the body of a live baboon. This record-breaking outcome gives researchers a ray of hope for the potential for xenotransplantation - the transplantation of animal organs or tissues into humans, to address worldwide organ shortages.Cross-species transplants provoke a powerful immune reaction, leading to rejection of the organ by the host. But a US-German team used a combination of gene modification and immune-suppressing drugs. Their work is described in the journal Nature Communications.If everything goes well and the experiment gets successful, animal organs can be used for transplantation in humans who are in desperate need of transplants but not getting any donor. Currently in the US, 22 people die every day just waiting for organs, which are in constant short supply.
