THE liver is the body's "comeback kid", capable of amazing feats ofregeneration. But biologists in Pennsylvania have now found that the key to theorgan's miraculous ability to repair itself could be cells migrating from bonemarrow.

He noted that the less dramatic increase in bone growth for the oral dosage groups was probably due to the fact that the orally-administe......eak down lactose.

By altering the diet over time, bacteria more effectively digest lactose, making milk very well tolerated." He recommends starting...... adds. The study plays on one of the brain's more amazing feats: every fall, a population of song-generating neurons in the so-called high vocal center of canaries dies off and the birds fall quiet.
