This is Science Today. An x-ray microscope developed
at the Lawrence Livermore National Laboratory may
help researchers treat osteoporosis. Lab physicist
John Kinney explains how.
It allows us to take extremely high spatial resolution
pictures in three dimensions without touching or
disturbing the tissue. The fact that it's three-dimensional
allows us really to look at a few of the longstanding
problems that have plagued mineralized tissue research.
One of those is the mechanical function of the tissue.
Researchers are using the x-ray microscope to study
the long term effects of bisphosphonates, a new
category of drugs which slow down the development
These treatments shut down bone remodeling and we
want to know what in the long term this will do
to the bone quality. Because if a woman begins taking
them at the ages of fifty, fifty-five years old,
what will their bone look like at the age of 75
or 80 years old? Can we understand what that will
be before we have to see it clinically?
