  • Patent number: 10632187
    Abstract: Disclosed is a hemagglutinin-binding peptide producing an anti-influenza virus effect higher than that of existing peptides. Also disclosed are hemagglutinin-binding peptides comprising a polypeptide having any of the following amino acid sequences (i) to (iv): (i) Thr-MeGly-Asp-MePhe-MePhe-Ser-MeSer-His-Tyr-Thr-Val-Pro-Arg (SEQ ID NO: 1); (ii) Arg-Val-Ser-MePhe-Thr-Tyr-MePhe-MeSer-Tyr-Thr-Pro-Ser (SEQ ID NO: 2); (iii) an amino acid sequence with deletions, additions, or substitutions of one or several amino acids in SEQ ID NO: 1 or 2; and (iv) an amino acid sequence having 90% or more sequence identity to that of SEQ ID NO: 1 or 2.
    Type: Grant

  • Patent number: 10328143
    Abstract: Object of the present invention is to provide a hemagglutinin-binding peptide producing an anti-influenza virus effect higher than that of existing peptides. The present invention provides, for example, a hemagglutinin-binding peptide comprising a polypeptide having any of the following amino acid sequences (i) to (iv): (i) Thr-MeGly-Asp-MePhe-MePhe-Ser-MeSer-His-Tyr-Thr-Val-Pro-Arg (SEQ ID NO: 1); (ii) Arg-Val-Ser-MePhe-Thr-Tyr-MePhe-MeSer-Tyr-Thr-Pro-Ser (SEQ ID NO: 2); (iii) an amino acid sequence with deletions, additions, or substitutions of one or several amino acids in SEQ ID NO: 1 or 2; and (iv) an amino acid sequence having 90% or more sequence identity to that of SEQ ID NO: 1 or 2.

  • Patent number: 8092383
    Abstract: To provide a method for recognizing/analyzing a plurality of data concerning health management of an individual as his/her personal characteristic pattern data while considering the relationship between the data instead of analyzing each of the data separately; a health support method provided by the method; and a system thereof. A support computer stores individual health data acquired in advance in individual data storage means and subjects the individual heath data extracted from the individual data storage means to a multivariate analysis, thereby setting a reference space of the individual, which is stored in reference data storage means. For the individual health data received from the user terminal, a Mahalanobis' generalized distance is calculated from the reference space of the individual read out from the reference data storage means and the health condition of the individual is judged according to the distance.
