Peptide Soup Good to Blood

Peptide “Soup” Halts Blood Loss. ‘Once severe bleeding starts, it’s hard to stop. Doctors can clamp blood vessels, cauterize wounds, and even administer vessel-constricting drugs, but millions of units of blood are still lost on the operating table each year. That may soon change, thanks to a new technique that uses a soup of protein building blocks to create a “blood plug” at the injury site. Researchers first reported on the healing properties of the peptide soup last March. When mixed from a powder and applied to hamsters with severed brain regions, the protein parts self-assembled into a scaffold, which helped the animals regrow nerve cells.’
