Tissue engineering and tissue healing have a common complication — it’s difficult to build new blood vessels throughout the rebuilt skin, but vasculature is required to keep the skin alive. This is especially problematic for victims of severe burns. A new customized sugary gel substance can work wonders to re-grow skin and the associated blood vessels, according to researchers at Johns Hopkins University.
Future stitches could be made out of your own muscle cells, ensuring proper re-growth of injured muscle tissues.
Researchers in Massachusetts are implanting injured mice with microthreads coated with human muscle cells, reports Technology Review. The threads are made of the same proteins the human body uses to heal wounds, and when seeded with muscle cells, they act as a scaffold for the construction of healthy tissue.
Researchers in Germany have created bandages that turn purple at the first sign of infection.
A new wound dressing, developed at the Fraunhofer Research Institution for Modular Solid State Technologies EMFT in Munich, includes a special dye that reacts to different pH values.
People who suffer massive blood loss automatically go into shock as a stopgap measure, but can eventually die if their bodies stay in shock for too long. Now a drug used to treat epilepsy could reverse all that and boost survival rates for horrifically injured people, especially wounded soldiers far from any extra blood supplies. New Scientist reports on a new study of the drug that involved porkers.
Ever since the first caveman ran through an adversary with a pointy stick, battlefield medicine has wrestled with the problem of blood loss from cutting and penetration. And while tourniquets can stop blood loss from an extremity, little can be done about large wounds to the chest and abdomen. That's where the TourniCath comes in.
In this micrograph of dorsal closure in a fruit-fly embryo, the protein actin is marked red, prominent around the gap in the epithelial cells. The microtubules that give shape to cells are green, and epithelial cells with their microtubules destroyed are blue.
One of the steps in fruit-fly development is similar to the healing of wounds. Until recently, scientists believed that when fruit-fly bodies take form during a process called dorsal closure, long strings of the protein actin behaved like the drawstring of a purse, pulling together the epithelial cells that eventually form the fly's skin.
Emergency medical care for soldiers wounded on the battlefield has come a long way since Hawkeye and Hot Lips. But for Special Forces troopers operating deep behind enemy lines, that care often remains out of reach. Blood loss in particular makes seconds count, and imperils commandos operating far away from friendly bases.
To help with the problem of blood loss from traumatic wounds, the military has started field-testing a device more Mandalorian than M.A.S.H.: a plasma knife.
