  • Polyamic acid, varnish containing same, film, touch panel display, liquid crystal display, and organic EL display
    Patent number: 11945911
    Abstract: The purpose of the present invention is to provide: a film having high thermal stability, high bending strength (tensile elongation), small retardation in the thickness direction, a low coefficient of thermal expansion, and high transparency; and a polyamic acid or varnish for obtaining the film. The film satisfies all of requirements (i)-(vi) below. (i) The average value of the coefficient of thermal expansion in the range of 100-200° C. is 35 ppm/K or less. (ii) The absolute value of the retardation in the thickness direction is 200 nm or less per 10 ?m of thickness. (iii) The glass transition temperature is 340° C. or higher. (iv) The total light transmittance is at least 85%. (v) The b* value in the L*a*b* color system is 5 or less. (vi) The tensile elongation is at least 10%.

  • METHOD FOR DETERMINING PRESENCE OR ABSENCE OF RISK OF DEVELOPING CANCER
    Publication number: 20220389517
    Abstract: An object of the present invention is to provide a method for predicting a risk of developing cancer. DNA samples were prepared from blood and cancer tissues of 2480 cancer patients and analyzed for the nucleotide sequences of exon regions using NGS. As a result, among the cancer patients, 7 patients were confirmed to have D49H mutation or A159D mutation which is a germ cell mutation.
