WINSTON-SALEM, N.C. — North Carolina researchers are trying to make sure the U.S. military isn’t fighting the war of the future while treating its wounded with medicine from the past.

Their work eventually could speed the growth of new skin over traumatic burns, replace lost arms and hands, restore disfigured faces and undo some of the other lasting damage of combat.

“It’s all about quality of life,” said Dr. Anthony Atala, director of Wake Forest School of Medicine’s Institute for Regenerative Medicine, which announced Tuesday that it will lead a five-year, $75 million federally funded effort to improve treatment options for severely wounded servicemen and women.

Researchers in the field of regenerative medicine work to engineer tissues and organs and develop healing cell therapies, either to replace or to help the body regrow what has been lost. The technologies and techniques developed to help wounded warriors could benefit civilian patients as well.

Better protective gear, improved medical treatment in the field and quick evacuation to hospitals have made it possible to save the lives of soldiers who would have died in past wars. But those who survive often have severe and disabling injuries, most of them caused by improvised explosive devices.

Atala and his researchers will work with colleagues at more than 30 institutions around the country to develop clinical therapies focused on:

    • Restoring function to severely traumatized limbs.
    • Regenerating tissue to reconstruct after facial and skull injuries.
    • Regenerating skin after burn injuries.
    • Preventing the rejection of transplants such as of the face and hands.
    • Reconstructing genital and urinary organs and the lower abdomen.

The projects will fall under the umbrella of the Armed Forces Institute of Regenerative Medicine II; the first five-year grant, for $42 million, ended last year. It, too, was led by Wake Forest researchers, who have been doing regenerative medicine studies for 25 years.

Besides traumatic brain injury, which has received most of the attention as the “signature injury” of the wars in Afghanistan and Iraq, burns and lost limbs are among the most common injuries, Atala said.

Both can have a severe impact on soldiers’ lives, often making it impossible for them to continue to serve in the military and difficult for them to adjust to civilian life.

Both are medical challenges, as well. Burn injuries often are treated with repeated skin grafts, and can result in restricted movement and heavy scarring.

Lost limbs can be replaced with prosthetics, but their comfort and usefulness varies.

Regenerative research is looking for ways to improve healing of burn injuries, such as spray-on skin cells that could be applied within days of the injury. Scientists also have had success with limb transplants using techniques to reduce the likelihood of rejection, so patients’ immune systems don’t have to be indefinitely suppressed.

Wake Forest researcher George Christ describes himself as “a muscle guy,” whose research has focused on how organs and tissues work and how they change over time. As people age, they have less tissue available to make injuries heal, Christ said. Soldiers who have lost full or partial limbs have essentially the same problem: a tissue shortage.

“If you run out of viable tissue, what’s the answer?” he asked. “You make more tissue, right?”

Rep. Ted Budd, left, and Cheri Beasley

On Tuesday, North Carolina Republicans selected Rep. Ted Budd (R-NC), a far-right extremist who has pushed false claims about the 2020 election, to be their Senate nominee. He will face Democratic nominee Cheri Beasley, a former chief justice of the state's Supreme Court.

As of Wednesday morning, Budd had received more than 58 percent of the GOP primary vote. Former Gov. Pat McCrory received just below 25 percent of the vote, while former Rep. Mark Walker received about nine percent of the vote.

Stephen Colbert

It seems we can't go even a week in America without some deranged white nationalist shooter taking the lives of decent people. Of course, this type of violence is propagated on a daily basis by the far-right sh*tweasals at Fox News and, worse yet, in the ranks of the Republican Party.

After returning to the Late Show helm, Stephen Colbert weighed in on the real culprit behind the mass shootings -- the Replacement Theory popularized by Tucker Carlson.
