  • Publication number: 20110245922
    Abstract: A material for filling bone defects has a flocculent three-dimensional structure composed of a fibrous substance containing a biodegradable resin as a principal component and further containing a siloxane. The material is produced by dissolving or suspending a substance in a solvent to give a solution or slurry of the substance, the substance containing the biodegradable resin as a principal component and further containing the siloxane, the solution or slurry having such a viscosity as to form a fibrous substance having an average diameter of 10 ?m or more; and carrying out electrospinning of the solution or slurry, in which the electrospinning is performed with air blowing. The flocculent three-dimensional structure is expected to show high cell invasion efficiency, because a two-dimensionally structured nonwoven fabric shows high cell invasion efficiency when it has an average diameter of 10 ?m or more.

  • Patent number: 7565192
    Abstract: A typical task assigned for measuring a brain activity signal lasts from 10 to 30 seconds. The frequency band of the Mayer wave noise signal is very close to the frequency bands of brain activity signals, a result, it is difficult to reduce the Mayer wave noise signal using a bandpass filter or a bandcut filter. Light irradiating units and light detecting units for detecting the emitted light that has been passed through or reflected within the tissue are provided. A biological signal measuring unit measures at least one of the pulsation, breathing, blood pressure, and temperature. The relationship between an optical signal obtained by the light detecting unit and a biological signal using non-linear analysis; and a computation for separating the biological noise signal from the optical signal on the basis of the obtained relationship.
