  • Publication number: 20240124571
    Abstract: Provided is a substance capable of effectively suppressing cancer metastasis or a pharmaceutical composition that effectively acts on an inflammatory disease. The pharmaceutical composition is a pharmaceutical composition containing, as an active ingredient, an antibody or an antibody fragment thereof having antigen-binding activity for an S100A8/A9 heterodimer, and blocks interaction between S100A8/A9 and a group of receptors therefor, to thereby strongly suppress cancer metastasis both in vitro and in vivo, or alleviate inflammation. That is, the anti-S100A8/A9 antibody or the antibody fragment thereof can strongly suppress cancer metastasis or alleviate inflammation, by virtue of its blocking action on the interaction between S100A8/A9 and the group of receptors therefor.

  • Patent number: 10564082
    Abstract: According to improvement of the receptor layer of various sensors of the type for detecting physical parameters (for example, a surface stress sensor, QCM, and SPR), all of high sensitivity, selectivity, and durability are achieved simultaneously. A porous material or a particulate material, e.g., nanoparticles, is used in place of a uniform membrane which has been conventionally used as a receptor layer. Accordingly, the sensitivity can be controlled by changing the membrane thickness of the receptor layer, the selectivity can be controlled by changing a surface modifying group to be fixed on the porous material or particulate material, and the durability can be controlled by changing the composition and surface properties of the porous material or particulate material.

  • Patent number: 10221753
    Abstract: A vehicle includes a radiator, a bypass passage, a first valve, a second valve, and a controller. Cooling water is circulated through the radiator independently of a cylinder block and a cylinder head of an engine. The radiator cools the cooling water. The cooling water is circulated through the bypass passage while bypassing the radiator. The first valve switches between an open state in which cooling water is circulated through the cylinder block and a closed state in which cooling water is not circulated through the cylinder block. The second valve receives cooling water circulated through the cylinder head and cooling water circulated through the cylinder block via the first valve. The second valve uses an intermediate opening to adjust a flow rate of cooling water circulated through the radiator and the bypass passage. The controller controls opening and closing of the first valve and the opening of the second valve.
