These natural approaches would be used to prepare a patient for transplant and activated when problems with rejection emerge. "I believe this natural mechanism is a very powerful tool f...

iSTART Brain Model Reveals the possible Cause of Autism

Researchers Beginning to Identify Genetic Culprits of Arthritis

...d Cook are determining the extent of abnormal gene expression in the knees of dogs and correlating it to MRI results, a clinically relevant assessment of arthritis. The implications of determining if a person will have arthritis are enormous. Lifestyle changes could be started before the disease even appears,...

Study Says - Blocking 'aP2' Protein Prevents Airway Diseases

... the windpipe to the lungs (bronchi), and that aP2 expression is significantly increased when these cells are stimulated with the molecules interleukin-4 and –13. This finding is very unexpected as aP2 has previously been considered to be a specific marker for fat cells. The group went on to show that mice lack...

So it looked like a smooth muscle cell, but would it act like one? The next step required testing functionality to see if the cells would expand and contract like smooth muscle t...

Gene Therapy Technique for Inherited Heart Problems in The Pipeline
