Cord blood may preserve insulin levels in children with type 1 diabetes
...he idea would be to intervene and repair any early damage
during the honeymoon period many patients enjoy -- the first several months after diagnosis during which insulin needs are minimal, he added. Our groups concept is that we wont be able to cure diabetes without a combination therapy approach, Haller...

... may be complete or partial. Such loss may involve damage
to inner ear cells called cochlear fibrocytes, which are fundamental to inner ear function. Some natural regeneration of these cells can occur after acute damage, leading to partial recovery of temporary hearing loss. But could such restoration be en...
Omega-3 fatty acids protect eyes against retinopathy, study finds
