The molybdenum enzymes sulfite oxidase and xanthine dehydrogenase have been investigated by fluorescence-detected EXAFS using synchrotron radiation, and the results have been interpreted with improved EXAFS analysis procedures. A new treatment of EXAFS amplitudes has been developed which allows the extraction of meaningful Debye-Waller factors using experimentally derived functions. A search pr...

Decontamination performance of some noticeable fission products from TRU elements by the TRUEX process was calculated with a multistage extraction simulation code. The batch extraction data of molybdenum, palladium, antimony, and cerium, which have been obtained in our related TRUEX studies, were provided for the calculation. For uranium, plutonium, and americium, literature data were used. A m...

A molybdenum cofactor which is capable of reconstituting demolybdosulfite oxidase purified from livers of tungstentreated rats has been identified in rat liver and various organisms. Reconstitution with the rat liver cofactor is directly proportional to cofactor and demolybdoenzyme concentrations and proceeds most efficiently in 0.01 M potassium phosphate buffer, pH 7.4. The activation process ...

Background: With the spread of nanotechnology, various nanoparticles with new and emerging properties have been produced and the potential toxic effects of the majority of these particles remains still unknown. The present study was conducted to determine the toxicity of Molybdenum Trioxide nanoparticles in blood and body tissues of male Wistar rats. Materials and Methods: Thirty Wistar rats w...
