New biologic treatment for tennis elbow may replace surgery for chronic sufferers

...PRP therapy to be useful in maxillofacial surgery, wound healing, microfracture repair, and in the treatment of plantar faciitis. Treatment with PRP is still considered investigational and further research is needed before it can be made available to the general population. "The body has an extraordinar...

Radiologists attempt to solve mystery of Tut's demise

...ings suggest that the injury may have been an open wound that became infected and ultimately fatal. Since King Tut was first examined by x-ray in 1968, revealing what appeared to be a bone fragment in his skull, it has been widely speculated that a blow to the head killed the boy king. However, Dr. Seli...

Scientists identify gene involved in stem cell self-renewal in planaria

...e of this protein, the stem cells could respond to wound stimuli, proliferate, and differentiate, but they were unable to self-renew. As a result, the regeneration process failed and the animals died." Using a technique called RNA interference, Illinois graduate student Tingxia Guo and Newmark first elimi...

Surprise finding for stretched DNA

... human DNA extends more than three feet, but, when wound up inside the nucleus of a cell, that same molecule measures about one millionth of an inch across. Biologists have long believed that as a molecule of DNA is stretched, its double helix starts to unwind. As much sense as this makes from an intuitiv...

New roles for growth factors: Enticing nerve cells to muscles
