Heat therapy relieves back pain

... It leads to the growth of new tissue full of pain receptors and to irritation of the spinal nerves. The IDET treatment destroys the painful tissue and is less invasive than traditional surgery for lower back pain, taking just 45 minutes to perform.

More about HIV

...munodeficiency virus is a retrovirus that binds to receptors found on membranes of immune system T cells. When HIV attacks a cell, the virus is internalized, copied into DNA, then migrates into the nucleus where it inserts itself as part of the host DNA. In many cases, the inserted viral genes remain dormant, ...
