    Elucidation of the structure of lignocellulose biomass is necessary to promote bio-refineries. Using solid-state and solution state nuclear magnetic resonance (NMR), the chemical composition and chemical shifts for structures in cellulose were determined. This approach contributes to an understanding of the complex structure of lignocellulose components.

    In order to realize an "artificial cellulosome" that converts crystalline cellulose into soluble sugar, we first investigated the clustering of different cellulase domains on organic and inorganic nano-carriers to generate a hybrid nano-cellulosome, and then identified self-assembling peptides for integrating cellulase domains without the need for nano-carriers.

    For efficient bioethanol production from cellulose, we found that S. cerevisiae is able to express scaffolding proteins via the mini CipA gene from C. thermocellum and to reconstitute minicellulosomes possessing cellulose saccharification activity on its surface. We also identified genes that contribute to enhancing this activity by using deletion mutants.

    We have established “on-chip ELISA” which viruses were immobilized on a polymer using a unique
    photo-immobilization technique. Commercially available digital camera could detect chemiluminescent
    signals. So we expect that this portable and cheap system would make a contribution for rude medical
    system in developing countries.

  • 6. Acute Effects of Environmental Factors on the Circulatory System: An Epidemiological Approach PDF(286kB)

    pages 39-49
    Hideo Nakane, Masahiro Taki, Mitsuhiro Kojima and Hiroshi Morimoto

    Acute effects of meteorological factors on the circulatory system were evaluated in patients who had been transported by ambulance in Nagoya. Temperature was the most prominent meteorological factor throughout the year. The cerebrovascular diseases showed a stronger relationship with meteorological factors than the cardiovascular diseases.
