Tiny Pellets Could Deliver Alzheimer's Drugs
... individual molecules of NGF with a polymer. These microspheres
might one day be injected into the affected areas ...mically so that it will bind with the polymer. The microspheres
have not yet been tested in rat brains. Saltzman speculates that this drug delivery system might we...
Abraham Rudolph To Receive Howland Medal For Contributions To The Advancement Of Pediatrics
...bornhumans. They pioneered the use of radionuclide microspheres
to find how bloodflow is directed in the fetal heart and circulatory system, and how thatcirculation changes at birth. The knowledge and techniques developed during thisresearch now help physicians diagnose and treat congenital heart defects. Among ...
Unergrad's invention may deliver life-saving medicine
...es of his particles. Krauland's goal is to produce microspheres
that are light and do not stick together when shot out of an aerosol device. The spheres must be capable of carrying large molecules such as DNA and proteins deep into the lungs, where they can be released into the body over a prescribed period of ti...

underneath the skin, probably in the abdomen or upper arm. The spheres contain special fluorescent molecules that are sensitive to glucose levels in the fluid surrounding the skin cells. When exposed to a special excitation light, the molecules fluor...
New material improves treatment of urinary incontinence

were well tolerated and remained in place. They al... called fibroblasts, invaded the space between the microspheres
and further anchored the material. The microspheres
have another advantage. Due to the presence of i...
Making tiny plastic particles to deliver lifesaving medicine
...antly, the components used to create these plastic microspheres
were materials already FDA-approved for other medical applications, making it more likely they will pose no health hazards to humans in their new polymeric form. Recent work by Hanes, doctoral candidate Michelle Dawson and associate professor Denis ...
Light-sensitive gloves reduce risk of germ transfer
