Considerations About PET Isotopes

Human beings, like all living organisms, are made of bio-molecules. Health can be considered as the expression of homeostasis, i.e., the ability of a system to regulate its internal environment, thereby tending to maintain a stable and “normal” condition. In this sense, the real essence of life is the phenomenon in which multiple dynamic equilibrium and regulation mechanisms are needed to make homeostasis possible. Many diseases result from disturbances in homeostasis and are characterized by a condition known as homeostatic imbalance, where a molecular system goes out of equilibrium.
