Augmenting Hypothermia Therapy for Hypoxic-Ischemic Encephalopathy in Neonates: Localizing Drug Delivery using pH and Temperature Responsive Nanoparticles
DownloadFall 2022
The obstruction of blood flow to regions of an infant brain leads to a reduction of oxygen and essential nutrients, causing what is known as hypoxic-ischemic (HI) damage to that region. Presently the only treatment available for affected neonates is hypothermia: head or whole-body cooling....
