Natural metals are proving very effective identifiers of diseased tissue and are even used as treatment carriers in today's nanotherapies. These compounds are known as theranostic agents because of their ability to both diagnose and deliver treatment to a tumor or other diseased site. Two Virginia universities have recently published the results of their theranostic discovery and its use for brain cancer treatment on animal models.

But the focus and originality of assistive treatments and therapy available for aged cats and dogs in Japan suggest that Japanese pet owners do not readily accept euthanasia for their furry family members.
