Nanoparticles Shaped Like Platelets Show Promise in Stopping Bleeding

Monday, November 17th, 2014

Researchers in the Department of Chemical Engineering and Center for Bioengineering (CBE) at UC Santa Barbara have created and are experimenting with nanoparticles that copy the shape, flexibility and surface biology of the body’s own platelets.

These tiny, platelet-shaped particles behave just like their human counterparts and can be added to the  to supply or augment the patient’s own natural platelet supply, stemming the flow of blood and initiating the healing process. Initial experimentation indicates that emergency situations can be brought under control faster, injuries can heal more quickly and patients can recover with fewer complications.

VCU Researchers Consider Vitamin C as Hemorrhagic Shock Treatment

Friday, November 7th, 2014

With a grant from the Department of Defense, researchers at Virginia Commonwealth University will begin studying the effect of high doses of vitamin C on platelet function. Their hope is that the treatment will retard organ failure due to heavy blood loss.

This study follows one that looked at using vitamin C to treat septic lung injury resulting from infection.  As published in the Journal of Translational Medicine in January, researchers found that high doses of vitamin C prevented the inflammatory responses from sepsis.
