Instead it lives in the nervous system in a dormant and inactive condition. When the virus becomes active in the nervous system, it causes shingles.

Stem Cells And Alzheimer Disease

Over the years, medical research has revealed various novel inventions that have enhanced the life span of human beings. The discovery of using stem cells in the treatment of various fatal diseases is one of the latest innovations in this respect. It is indeed astonishing that something as simple as stem cells that are present in all multi-cellular organisms can become saviors of human life. This aspect was highlighted for the first time in the decade of the 1960s by two scientists from Canada -- Ernest A. McCulloch and James E. Till.
