  • Polycarbonate resin composition, molded article, and multilayer body
    Patent number: 11873370
    Abstract: A polycarbonate resin composition may include a first polycarbonate resin and a second polycarbonate resin, which a molded article may include, and a multilayer body may have a resin layer A including the polycarbonate resin composition and a resin layer B including a resin different from the resin layer A. The first polycarbonate resin may include 40% by weight or more of a structural unit of formula (1) The second polycarbonate resin may include less than 40% by weight of the structural unit of formula (1). The weight ratio of the first polycarbonate resin to the second polycarbonate resin, the first polycarbonate resin/the second polycarbonate resin, may be in a range of from 55/45 to 99/1. The polycarbonate resin composition may have two or more glass transition temperatures.

  • METHOD FOR PREDICTING EFFICACY OF TREATMENT OF LUNG CANCER PATIENT USING IMMUNE CHECKPOINT INHIBITOR
    Publication number: 20230204586
    Abstract: A method for predicting efficacy of treatment of a lung cancer patient using an immune checkpoint inhibitor includes isolating exosomes from a biological sample derived from the lung cancer patient, and determining an expression level of a protein present in the exosomes by a mass spectrometry method, in which the protein is one or more proteins selected from the group of proteins shown in Table 1-1 to Table 1-6.
