Theory Simplified: Iron - Ferrochelatase - Porphyrin Manganese - Tellurium - MPTP 1. Manganese prevents the breakdown of iron to be used by Ferrochelatase and causes Parkinsons. 2. MPTP inhibits Porphyrin that uses this broken down iron and causes Parkinsons. 3. Tellurium is a sulphur - like metal that can become part of Ferrochelatase, which takes the iron if manganese is not there and gives it to porphyrin if MPTP is not there, and I think it causes Parkinsons too. 4. When iron does not break down from ferric iron to ferrous iron, the ferric iron combines with dopamine which causes a reaction called lipid peroxidation that destroys neuromelanin cells. Tellurium was considered by NIEHS, but rejected because it was too rare. I think it was rejected because the idea of bacteria inside human beings creating tellurium from tellurites and tellurates was not considered. Bacteria (not viruses) absorb tellurite and turn it into tellurium. It is how scientists tell if a bacteria is gram positive or negative. Tellurium was also rejected because of history, it was discovered in 1782 by Muller von Reichenstein, named by Klaproth who isolated it in 1798. Tellurium is occasionally found native, but is more often found as the telluride of gold (calaverite), and combined with other metals. But I found it does occur naturally in mineral waters when I found the article of 1911 Mount Clemens Mineral water that included sodium telluride, and this potion was distributed as a health cure. Did you know that gold can cause seborrhea dermatitis often experienced by Parkinsons People? Did you know the antagonist of tellurium is selenium which is used to treat this seborrhea dermatitis? I found tellurium used as an antiknock additive of gasoline and used to vulcanize rubber, like in rubber tires. Those studying Parkinsons at NIEHS were not aware of this. Lactoferrin or iron in milk can be absorbed by bacteria along with tellurium Vulcanite contains copper-tellurium or CuTe, and copper is implicated in Alzheimers. Tellurium also bursts open haemoglobin, releasing iron if it gets in touch with red blood cells. Porphyrin is used to make haemoglobin. Dr. Andrew J Larner in 1996 put forth the theory of Tellurium as a cause of Alzheimers Disease. N-Methyl would carry the tellurium to the brain through the blood brain barrier. I don't think anyone took him seriously because they were again not thinking of the conversion of tellurites to tellurium by bacteria that live in the human gut. There are no studies being done on tellurium and Parkinsons Disease. If anyone can think of a way to get this information to those who can do research in this area it would be appreciated.
