New Procedure Repairs Severed Nerves in Minutes, Restoring Limb Use in Days or Weeks

Team apply new procedure to rapidly induce nerve regeneration in mammals

American scientists believe a new procedure to repair severed nerves could result in patients recovering in days or weeks, rather than months or years. The team used a cellular mechanism similar to that used by many invertebrates to repair damage to nerve axons. Their results are published today in the Journal of Neuroscience Research.

Extreme Heat Related Injuries Can Be Prevented

Dr. Pat Crocker knows better than most that it’s dangerously hot in Central Texas these days.

“We are in an exceptionally hot period — a 100-year drought with 106-, 107-degree days. So we’re at a higher risk for heat injuries, and it just makes sense for people to be extra careful,” said Crocker, chief of emergency medicine at Dell Children’s Medical Center.

That includes the high school football players and coaches found on sweltering, sun-baked fields.

In protecting young athletes from heat-related illnesses, Crocker said, “there are a number of things that have clear value because most, if not all, exertion-related heat injuries are preventable. Continue reading

Leprosy in the US Linked to Armadillos

Armadillos, with their sharp claws and body armor, don’t have a reputation for being cuddly. New research should make them even less so. They turn out to be a potential source of leprosy in genetically-susceptible humans.

Researchers report in the New England Journal of Medicine that a strain of leprosy found in humans in the southern United States is identical to the one common in nine-banded armadillos in the region.

The findings mean people should be discouraged from frequent contact with the animals, or cooking and consuming armadillo meat.

The results also suggest that species  Continue reading
