  5. It is estimated that there are two million people in the United States that have lost a limb and another 185,000 each year that will lose a limb. Artificial limbs, or prosthetics, can restore some normal function but are expensive and sometimes not covered by insurance. Touch sensors are often used to alert a user when the prosthetic has come into ...

  7. Multinucleated giant cells (MGCs), formed from macrophage fusion, occur as a consequence of a number of pathological conditions in the body. MGC formation can be particularly destructive to synthetic implants, as it etches their surface, and could lead to implant failure. Despite significant research into macrophage fusion, there are many underlyi...
