  • Patent number: 9745378
    Abstract: The present inventors obtained, from a phage library of human antibodies, an anti-mouse NR 10 neutralizing antibody-expressing BM095 clone that shows a strong proliferation-suppressing activity in an IL-31-dependent Ba/F3 cell proliferation assay system. When this anti-mouse NR 10 neutralizing antibody was administered to NC/Nga mice, a model of atopic dermatitis which is a mouse model of chronic dermatitis that arises as a result of repeated applications of picryl chloride, a mouse model of rheumatoid arthritis, and a mouse model of osteoarthritis, a significant effect of symptom suppression was observed. This revealed that the anti-NR 10 neutralizing antibody is indeed effective as a therapeutic agent for inflammatory diseases. In addition, the present inventors successfully obtained an anti-human NR 10 neutralizing antibody, providing extremely useful therapeutic agents with practical clinical applications.

  • Patent number: 8617299
    Abstract: A canister includes a first fuel vapor adsorption device and a second fuel vapor adsorption device. The second fuel vapor adsorption device can adsorb a part of fuel vapor that still remains in a gas after desorption by the first fuel vapor adsorption device. The second fuel vapor adsorption device includes a first passage containing a fuel vapor adsorption material and a second passage containing no fuel vapor adsorption material. The first passage and the second passage allow the gas to flow therethrough. A gas introduction device allows the fuel vapor to flow from the second passage into the first passage.

  • Patent number: 8474439
    Abstract: A fuel vapor processor has a fuel tank, a canister, a recovery pipe, a fuel pump, a negative pressure generator, a pressure regulator, a fuel intake pipe and a fuel intake regulator. The vapor pipe leads the fuel vapor generated in the fuel tank into the canister for trapping the fuel vapor. The recovery pipe connects the fuel tank and the canister for recovering the fuel vapor trapped in the canister into the fuel tank. The fuel intake pipe directly connects the fuel pump provided in the fuel tank with the negative pressure generator for leading fuel to the negative pressure generator. The negative pressure generator generates negative pressure depending on an amount of fuel supplied to the negative pressure generator from the fuel pump. The fuel vapor trapped in the canister is recovered to the fuel tank through the recovery pipe due to the negative pressure. The pressure regulator is connected with the fuel pump for returning excess fuel discharged from the fuel pump into the fuel tank.

  • Patent number: 8431127
    Abstract: The present inventors isolated clone BM095 from a human antibody phage library, which had a strong growth inhibitory activity in the IL-31-dependent Ba/F3 cell growth assay system. When administered to pruritus model mice, the anti-mouse NR10 neutralizing antibody exhibited a marked symptom-suppressing effect. Thus, it was revealed that anti-NR10 neutralizing antibodies are useful as therapeutic agents for pruritus.

  • Publication number: 20120186563
    Abstract: A canister has a canister case, an adsorbent chamber defined in the canister case, and an adsorbent disposed in the adsorbent chamber. The adsorbent can adsorb fuel vapor as the fuel vapor flows through the adsorbent chamber in a first direction. On the other hand, the adsorbent allows desorption of fuel vapor as air flows through the adsorbent in a second direction opposite to the first direction. The adsorbent chamber includes a first adsorbent chamber and a second absorbent chamber communicating with each other. The first adsorbent chamber is disposed on an upstream side of the second adsorbent chamber with respect to the first direction. The adsorbent includes a first adsorbent disposed in the first adsorbent chamber and a second adsorbent disposed in the second adsorbent chamber. A desorption promoting device is disposed in the second adsorbent chamber and can promote desorption of fuel vapor from the second adsorbent.
