Biochemical Pharmacology, 1985
Administration of non-cholestatic doses of manganese (Mn2+) followed by injection of bilirubin (BR) results in a severe reduction in rat bile flow. Male Sprague-Dawley rats were given various doses of Mn2+ (2, 4.5, 8, and 18 mg/kg, i.v.) and killed 0.25, 1, 3, or 5 hr later.

Manganese (Mn) is an essential metal that is required as a cofactor for many enzymes and is necessary for optimal biological function. Mn is abundant in the earth's crust and is present in soil and well water. Mn is also found in industrial settings, including mining, welding, and battery manufacture.

Transition metal complexes with metal-to-ligand charge transfer (MLCT) luminescence and photoactivity typically rely on precious metals such as ruthenium or iridium. Now, two complexes of the Earth-abundant 3d manganese have displayed room-temperature MLCT luminescence in solution and a unique excited-state reactivity.

Nature, 1964
AQUEOUS systems were reported earlier in which a manganese-phenothiazine auto-oxidation led to the emergence of semiquinone free-radicals of the drugs1. The mildness of the required conditions permitted the postulation that this interaction might be relevant to the pharmacological action of these agents2.

Manganese (Mn) is an essential trace metal that is pivotal for normal cell function and metabolism. Its homeostasis is tightly regulated; however, the mechanisms of Mn homeostasis are poorly characterized. While a number of proteins such as the divalent metal transporter 1, the transferrin/transferrin receptor complex, the ZIP family metal transporters

Manganese and radioactive manganese in liver cell nuclei
Biochimica et Biophysica Acta (BBA) - Specialized Section on Biophysical Subjects, 1964Abstract The turnover of manganese in cell nuclei of rat liver has been investigated using 54 Mn as radiotracer in conjunction with chemical determination of Mn contents. The mean Mn concentrations of nuclei and of liver were 12.4 and 10.9 μg per g dry wt., respectively.

Manganese plays an important role as a cofactor in many enzymatic reactions in humans but in excess amounts can cause irreversible nervous system damage. Although manganism is a rare condition, it can be the cause of complex nervous system symptoms, especially in the setting of environmental exposure.

Reduced Manganese Moment in Manganese Chromite
Journal of Applied Physics, 1966The net magnetization, magnetic susceptibility, 55Mn nuclear magnetic resonance, and neutron-diffraction properties of MnCr2O4 have been reinvestigated. Our results are in general agreement with earlier findings. The neutron-diffraction pattern of MnCr2O4 evidences appreciable deviation from a pure spiral configuration.

Abstract Children can be exposed to many hazardous metals in the environment, including fluoride and manganese. Sources of exposure may include drinking water, foods and dietary supplements, and metal-containing particles released into the air from industrial and vehicular sources.

Reduction of Colloidal Manganese Dioxide by Manganese(II)
Journal of Colloid and Interface Science, 2002The reduction of colloidal MnO(2) by Mn(2+) in aqueous HClO(4) has been studied by a spectrophotometric method. The reaction product is Mn(III). The reaction is of first order in both colloidal MnO(2) and H(+), whereas it presents a fractional order (0.58+/-0.02) in Mn(2+).
