According to a Northwestern Medicine study, only one in four students with asthma and half of children with food allergies have emergency health management plans in place at school. This underutilization leaves schools inadequately prepared to handle medical emergencies and puts the most vulnerable students at risk.
Researchers have identified marmosets as an ideal animal model to study Middle East respiratory syndrome corona virus (MERS-CoV) due to their DPP4 protein's similarity to humans. The marmoset model recapitulates severe respiratory symptoms seen in human patients, making it a promising candidate for future therapeutic studies.
