  • Patent number: 8300093
    Abstract: A method capable of obtaining a fluorescence image and a background image with a simple configuration. A color image is obtained, when excitation light is emitted on a subject, by imaging excitation light reflected from the subject and fluorescence emitted from the subject. Thereafter, an estimated spectral image that includes a background image representing the excitation light and a fluorescence image representing the fluorescence is generated by allocating a wavelength component of the excitation light and a wavelength component of the fluorescence included in the obtained color image to different primary color components.

  • Publication number: 20110318759
    Abstract: The inventions provides a method for immunologically determining a keratan sulfate level which method includes bringing an anti-keratan sulfate monoclonal antibody into contact with a biological sample, the anti-keratan sulfate monoclonal antibody exhibiting a relative reaction specificity between keratan sulfate-I and keratan sulfate-II represented by IC50KS-I/KS-II of 0.4 to 5, to thereby provide a signal; and detecting keratan sulfate contained in the biological sample from the signal. On the basis of the method, the invention also provides a joint disease detection method and a method for assessing the effect of a remedy for a joint disease and a candidate substance therefor. Through these methods, a very small amount of keratan sulfate contained in a sample, can be determined. Particularly, these methods can determine, at high-sensitivity and high-specificity, the total keratan sulfate including keratan sulfate-I, which have been difficult to determine through a conventional technique.

  • Patent number: 8038609
    Abstract: An endoscope apparatus used in combination with a near infrared light irradiation unit that irradiates near infrared light on a target irradiation section. White light and the infrared light are irradiated on a target observation area including the target irradiation section. The imaging means spectroscopically images a reflected light image of the target observation area, which is outputted as a spectral image signal. The storage section includes estimated matrix data. The IR image signal generation means generates an IR image signal constituted by an estimated value of reflected light intensity of the near infrared light by performing a matrix operation on the spectral image signal using the estimated matrix data and spectral matrix data of the near infrared light. The color image signal generation means generates a color image signal based on the spectral image signal and the IR image signal.

  • Publication number: 20110244789
    Abstract: An optimum path storage unit stores optimum paths on all wireless communication devices that can be destinations of data. A reception unit receives relay data as a relay target. A QoS judgment unit reads out an optimum path corresponding to a QoS requirement of relay data from the optimum path storage unit and judges whether or not the QoS requirement of data is satisfied by the optimum path. The QoS judgment unit outputs relay data to a transmission unit when it is determined that the QoS requirement is satisfied. The transmission unit transmits the relay data to the next node on the optimum path. When the QoS requirement of the relay data is not satisfied by the optimum path, a NACK information generation unit generates NACK information that includes the fact that transmission of the relay data has been interrupted and transmits the NACK information to neighboring wireless communication devices.
