How manganese produces a parkinsonian syndrome

Using X-ray fluorescence at synchrotrons DESY and ESRF, researchers in the Centre d'Etudes Nucléaires de Bordeaux Gradignan (CNRS/Université de Bordeaux) have demonstrated the consequences of a mutation responsible for ...

Scoliosis linked to essential mineral

Nobody knows why some children's backs start to curve to one side just as they hit puberty. Most children diagnosed with scoliosis, or curvature of the spine, have no known risk factors.

Study paves way for new approach to cancer diagnostics

Radiotherapy is an important form of treatment for cancer patients but, currently, treatment is largely "one size fits all." However, a new study points to the potential for treatment to become more tailored to the tumour.

Manganese

Manganese ( /ˈmæŋɡəniːz/ mang-gə-neez) is a chemical element, designated by the symbol Mn. It has the atomic number 25. It is found as a free element in nature (often in combination with iron), and in many minerals. As a free element, manganese is a metal with important industrial metal alloy uses, particularly in stainless steels.

Manganese phosphating is used as a treatment for rust and corrosion prevention on steel. Depending on their oxidation state, manganese ions have various colors and are used industrially as pigments. The permanganates of alkali and alkaline earth metals are powerful oxidizers. Manganese dioxide is used as the cathode (electron acceptor) material in standard and alkaline disposable dry cells and batteries.

Manganese(II) ions function as cofactors for a number of enzymes in higher organisms, where they are essential in detoxification of superoxide free radicals. The element is a required trace mineral for all known living organisms. In larger amounts, and apparently with far greater activity by inhalation, manganese can cause a poisoning syndrome in mammals, with neurological damage which is sometimes irreversible.
