  • Publication number: 20220404363
    Abstract: As a technique enabling to simply and accurately diagnose human T cell leukemia virus type 1 (HTLV-1) related disease, there is provided a diagnostic method for an HTLV-1 related disease based on an amount of tumor necrosis factor receptor 2 (TNFR2) in a blood sample taken from a subject, wherein (1) it is determined based on an increase of the amount of TNFR2 that the subject suffers from, or is likely to develop, the HTLV-1 related disease; and/or (2) it is determined based on a decrease of the amount of TNFR2 that the subject is in remission, or is likely to be in remission, of the HTLV-1 related disease.

  • Publication number: 20210391031
    Abstract: A method of ranking epitopes derived from neoantigens as targets for personalized immunotherapy includes collecting candidate epitopes based on patient data of a cancer patient. A set of scores are calculated for each of the candidate epitopes, each of the scores in a respective one of the sets for a respective one of the candidate epitopes representing an independent measure of a likelihood of the respective one of candidate epitopes to elicit an immune response in the cancer patient. The scores in each of the sets of scores are combined into a single score for each of the candidate epitopes. The single scores for the candidate epitopes in each case reflect an overall likelihood of eliciting the immune response in the patient. The candidate epitopes are ranked using the single scores for the immunotherapy.

  • Patent number: 9390313
    Abstract: A partial image extracting unit extracts images of a predetermined size and constant magnification from a tissue region. A mask generating unit generates a mask for removing a region not intended for measurement from the tissue region for each extracted image. A complete mask generating unit generates a temporary complete mask in which the masks generated for each of the images are integrated together, and generates a complete mask in which close portions among unmasked portions in the temporary complete mask are unified into one or more target regions. A measuring unit measures information pertaining to an object to be measured included in the image, and this information is measured for each of the images extracted by the partial image extracting unit. A region information calculating unit calculates, for each target region, information pertaining to the object to be measured from the measured information and from the complete mask.
