For the non-scientists, meta-analyses combine similar small studies together in an attempt to better assess the effects of a treatment. Meta-analyses are often considered the final word on the effects of those treatments, although there are serious limitations to this approach. When studies have different designs or inclusion parameters, deciding which studies to combine and which to leave out of the analyses is too often subject to investigator bias.

The October 7th, 2006, launch of the Just Say Know to Prescription Drugs campaign, aimed at getting one million people to stop and reevaluate the medications they have been prescribed, has secured amazing support from main stream medical professionals who are getting involved and drawing their social and professional networks into the campaign. One explanation for this positive response is that the Just Say Know to Prescription Drugs campaign was intentionally designed to be a positive intiative. The chairman of the campaign, Dr. Dominick Riccio, was quoted as saying, "Rather than being against any industry, organization, policy, practice, individual or group of individuals, the campaign is designed to get people to do what they can do to protect themselves. So far the approach seems to be resonating loudly."

Multipotent hemopoietic stem cells (MHSC) are found in the bone marrow. These precursor cells are responsible for the continuing formation of our blood cells, including our immune system leukocytes (white blood cells). Leukocytes include monocytes, macrophages, neutrophils, basophils and eosinophils.

Our genes are formed from microscopic double-strands of deoxyribonucleic acid (DNA). They are dependent on adequate nutrition for their structure and activity. By appropriately switching on and off (this is called transcription in the genome research world) our genes direct the behavior of our body's 60 trillion cells. Many genetic researchers consider our genes to be the Rosetta stone of health and disease.

"There are three topics in modern science that have caused more controversy than stem cells " the development of nuclear bombs, the notion that the sun is at the center of our solar system and the theory of evolution," so says Michael Stebbins, PhD, the director of biology policy for the Federation of American Scientists and a former US congressional fellow in science policy.
