  • Publication number: 20250027949
    Abstract: An evaluating method includes an evaluating step of evaluating a relative pharmacological action of a combination of an immune checkpoint inhibitor and an anticancer drug as a combination drug compared with a pharmacological action of an immune checkpoint inhibitor alone in a subject to be evaluated, using (i) a concentration value of at least one metabolite among Glu, Arg, Orn, Cit, His, Val, Phe, Tyr, Met, Pro, Asn, Leu, Lys, Thr, Ile, Gln, Ala, Ser, a-ABA, Trp, Gly, AnthA, hKyn, hTrp, Kyn, KynA, NP, QA, and XA in blood of the subject to be evaluated, or (ii) a value of a formula in the absence of use of an anticancer drug as a combination drug and a value of the formula in the presence of the use that are calculated using the concentration value and the formula including an explanatory variable to be substituted with the concentration value and an explanatory variable on the presence or absence of the use.

  • Patent number: 9304234
    Abstract: Plasmonic condensers for generating surface plasmon at an evanescent wave surface can include a substrate layer, a metal layer comprising the evanescent wave surface; and a media layer disposed between the metal layer and the substrate layer. The media layer can be active or passive and can include a source of radiation that interacts with the metal layer to create surface plasmons that are not substantially optically detectable as far field radiation until an interfering object is brought into proximity with the evanescent wave surface. When an interfering object such as a sample or specimen is brought into proximity with the evanescent wave surface, it causes coupling of at least some of the surface plasmons into propagating radiation detectable by an objective lens. Systems, methods, and the like are disclosed, as are features of a plasmonic meta-materials illuminator.
