Demolybdo nitrate reductase (also called cyt c reductase) of Chlorella vulgaris has been converted to active nitrate reductase by insertion of Mo from Na2MoO4 in vitro. A procedure is described which consistently gives about 0.3 unit of nitrate reductase from about 6 units of cyt c reductase, a yield of 30% of the maximum expected, if we calculate on a basis of a ratio of 6 to 1 for the cyt c r...
188Re (Rhenium) is easily obtained from an in-house 188W/188Re generator that is similar to the current 99Mo/99mTc generator, making it very convenient for clinical use. This characteristic makes this radionuclide a promising candidate as a therapeutic agent. Polyethylenimine (PEI) is a cationic polymer and has been used as a gene delivery vector. Positively charged materials interact with cell...
In order to establish a self-sufficient supply of (99m)Tc, we studied feasibilities to produce its parent nucleus, (99)Mo, using Japanese accelerators. The daughter nucleus, (99m)Tc, is indispensable for medical diagnosis. (99)Mo has so far been imported from abroad, which is separated from fission products generated in nuclear reactors using enriched (235)U fuel. We investigated (99m)Tc produc...
The radioisotope Technetium-99m has unique chemical and nuclear properties; which is widely used in the field of nuclear medicine. This isotope has a half-life of 6.04 hours and the emitted gamma ray has energy of 140.5 keV. This radioisotope is not normally found in nature, but is obtained from radioisotope molybdenum99 decay. molybdenum99 has half-life of 66 hours, and 740 keV Gamma-ray....
