Study gives nod to drug-eluting stents in heart attack

Although drug-eluting stents have become widely used for the treatment of stable coronary artery disease, many cardiologists choose bare-metal stents for patients with heart attack, or myocardial infarction (MI), citing conflicting data about the safety and effectiveness of drug-eluting stents in this patient group.

Discovery of role of rare gene mutations in schizophrenia

Using an important new method that can be applied in the study of other psychiatric illnesses, scientists at Cold Spring Harbor Laboratory (CSHL) in collaboration with colleagues at the University of Washington (UW) and the National Institute of Mental Health (NIMH), have identified multiple, individually rare gene mutations in people with schizophrenia that may help explain how that devastating illness is caused.
