LONDON – Scientists at a Massachusetts company seeking to make pig organs safe enough to be transplanted into humans have used gene-editing technology to clone piglets that lack a potentially dangerous retrovirus, according to a study released Thursday. The breakthrough, according to authors of the study published in the journal Science, could help pave the way for transplantation of whole pig organs into humans, without fear of patients being infected with the pig retrovirus. Transplants from pigs could offer a new potentially life-saving alternative for patients diagnosed with organ failure and no other viable treatment options. A shortage of available human organs has led scientists to study the possibility of animal donors to close the gap. About 20 people die each day in the United States while awaiting an organ transplant, according to the United Network for Organ Sharing.
A new algorithm developed by scientists at UCLA may bring us as close to fortune telling as we'll ever get. The computation is able to predict life expectancy of heart failure patients, and can tell how long they will live if they do or do not receive a heart transplant. This will help doctors when making decisions on patients awaiting heart transplants. The algorithm is called the Tree of Predictors and is detailed in a study published online in PLOS One. The Tree of Predictors uses 33 data points to assess patients awaiting a heart transplant, such as their age, gender and body mass index in order to understand how long a patient would live with or without a heart transplant.
