UNC launches study of liver injury caused by drugs

... said. Researchers will use DNA analysis based on blood samples to identify possible genetic risk factors for such liver injury. "Once a drug has been associated with severe liver injury, physicians are understandably hesitant to prescribe it, even if it may provide the best benefit for that patient," sa...

Leprosy microbes lead scientists to immune discovery
