Publications and cited

Until 1995, we contributed to early detection of rare diseases in Japan through organic acid analysis using gas chromatography-mass spectrometry. Based on that experience, we have launched innovative diagnostic support called metabolomics earliest in the world.

Mass Spectrom Rev. 1996; 15: 43-57 is cited as the most advanced application of metabolomics, in papers written by remarkable overseas researchers who lead the world at the forefront of metabolomics.
