Biological and chemical stimulators cause tissue injury. Many epidemiological studies imply that chronic stimulation of tissues leads to cancer. One of the most important type of chronic tissue stimulation criteria is increased activity of the metabolic pathway of arachidonic acid and production of biochemical intermediates. Cyclooxygenase pathway (COX) of arachidonic acid leads to production o...
Chelation enables metals to be transported to or from vulnerable target sites, and to hinder or facilitate their carcinogenic potential. In the reverse sense, metals are capable of ligand scavenging via complexation or mixed complex formation--the latter being the result of interaction with binary complexes. Consequently, metal complexes can be utilized for the transport of selected organic che...
