For this, the team had produced recombinant viral proteins which could be used to generate an antigen-antibody reaction, that can be detected during tests.They also added that the formation on the viral gen...

Computer Program can assist to detect Heart Attack

.... Several studies have shown that the network can detect heart attack in patients with chest pain, but Baxt and his colleagues set out to see how well the technology worked when some of the information it uses to make a diagnosis was missing.
