Abstract: An information providing method includes: generating first information indicating that a user who is interested in first content is relaxing, when (i) a current behavior of the user includes a predefined behavior and (ii) the first content included in information on communication content and second content included in information indicating a shopping history are the same content; obtaining, from a second information processing apparatus connected to a first information processing apparatus, information indicating first request content over a network; and when content of the first information is included in the first request content, outputting, to the second information processing apparatus, second information including information for identifying the user or a space, using the generated first information.

Abstract: A method for detecting anti-deoxyhypusine synthase autoantibody in a subject, wherein the method includes detecting, in a blood, serum, or plasma sample from a test subject with digestive system cancer, the amount of anti-deoxyhypusine synthase autoantibody, wherein the autoantibody is able to bind to a polypeptide consisting of the amino acid sequence of SEQ ID NO: 1.

Abstract: The present inventors have surprisingly found that a deoxyhypusine synthase (DHPS) gene, which was previously reported to correlate with prostate cancer and cervical cancer, is highly responsive to arteriosclerosis or digestive system cancer, whereby the gene can be used as a desired marker for arteriosclerosis or digestive system cancer. The present invention has been accomplished on the basis of this finding. Specifically, the present invention provides a method for determining arteriosclerosis or digestive system cancer, which method includes detecting expression of a deoxyhypusine synthase gene in a test sample (preferably a blood sample), and determining arteriosclerosis or digestive system cancer of a test subject from which the test sample has been obtained, on the basis of an increase in the gene expression as an index.

Abstract: The present invention provides a brain tumor marker, characterized in that the brain tumor marker is at least one protein expressed in a brain tumor tissue and selected from the group of proteins having the amino acid sequences represented by SEQ ID NOS: 1 to 16, respectively, wherein the protein is expressed in at least one tissue selected from the group of the tissues of a highly malignant brain tumor, a low malignant brain tumor, a drug-sensitive brain tumor, and a drug-resistant brain tumor; a polynucleotide encoding the brain tumor marker; and a method of diagnosing brain tumors by using the brain tumor marker or the polynucleotide as an indicator.

Abstract: The present invention provides a method for amplifying mRNA in ultramicroquantity by approximately 108 times which is possible to apply for generating a cDNA library, subtraction cloning, generating and analyzing a microarray, and analyzing a gene expression. After making mRNA of sample adsorbed to oligo (dT)-bound magnetic beads, a double-stranded cDNA is synthesized on magnetic beads, an antisense strand cDNA-bound magnetic beads are eliminated after adding a linker containing T7 promoter sequence at the 5′ end, by using a sense strand cDNA in supernatant as a template and using an oligo (dT) primer wherein a linker containing SP6 promoter sequence is added, a double-stranded cDNA is synthesized again, the cDNA mixture is amplified by PCR using a known sequence at a linker part of the both ends of said double-stranded cDNA as a primer. In addition, sense strand/antisense strand cRNA is synthesized by T7 or SP6 polymerase using said cDNA mixture.
