Rapid innovation in the biomedical industry is driven by a continuous flow of scientific and technological advances
Signs & Symptoms In vivo Imaging Techniques In vitro Laboratory Tests Molecular diagnostics is at the core of the personalized medicine vision Diseases will be diagnosed long before the patient begins to manifest any evidence using traditional tools Molecular Diagnostics …and biomarkers will be a primary tool
Conceptual model for timing the arrival of personalized medicine

“In conclusion, I return to the theme with which this article began. Claude Bernard’s concept of the constancy of the internal environment was the first example of multilevel functionality. It was critical in defining physiology as a subject distinct from the applications of physics and chemistry.(…)” Claude Bernard, the first systems biologist, and the future of physiology Denis Noble, ExpPhysiol93.1 pp 16–26, 2007
“(…) The challenge we face today resembles that faced by Bernard in the mid-nineteenth century, but the chemistry involved is that of the molecule DNA. The answer though should be much the same. Higher-level control cannot be reduced to lower-level databases like the genome. A major part of the future of physiology surely lies in returning to our roots. Higherlevel systems biology is, I suggest, classical physiology by another name. Claude Bernard, the first systems biologist, and the future of physiology Denis Noble, ExpPhysiol93.1 pp 16–26, 2007
CONCLUSÃO “Plus ça change, plus çadevient la même chose”
