  • Patent number: 11534528
    Abstract: Gamma ray and e-beam irradiation provided efficient sterilization of certain self-assembling peptides (including RADA16 in solution) without substantial degradation of the major peptide, while, e.g., another self-assembly peptide, QLEL12 was significantly degraded following irradiation. Irradiation sterilization enhances the rheological property of, for example, RADA16 hydrogel once applied to tissue at a physiological pH. The rheological property increase can result in higher efficacy in a variety of biomedical applications.

  • Publication number: 20220357157
    Abstract: An image-processing method includes a measurement step, an index calculation step, a comparison step, and a selection step. A processor measures a distance at each of two or more points in one or more images of a subject in the measurement step. The processor calculates a first index or a second index on the basis of the distance in the index calculation step. The processor compares the first index or the second index with a threshold value in the comparison step. The processor selects at least one image included in the one or more images in the selection step when the first index is greater than the threshold value or the second index is less than the threshold value.

  • Patent number: 11426052
    Abstract: An endoscopic system includes a left optical system having a first focal position, a right optical system having a second focal position that is different from the first focal position. An image capturing device generates a first image and a second image respectively from images of a subject that are obtained by the left optical system and the right optical system. A display device displays the first image or the second image. A proper image determiner determines the magnitude relationship between the position of the subject in a predetermined area displayed on the display device and at least one threshold value Th is established between the first focal position and the second focal position. A video signal processor switches to the first image or the second image depending on a determined result from the proper image determiner and displays the image on the display device.

  • Publication number: 20220136820
    Abstract: An image display method includes a determination step, a generation step, and a display step. A processor refers to a reference model indicating a figure expanding two-dimensionally or three-dimensionally in a three-dimensional space including two or more points and determines whether or not a positional relationship between each of the two or more points and the reference model meets a condition that is set in advance in the determination step. The processor generates an image and differentiates a display state of a pixel corresponding to a first point from a display state of a pixel corresponding to a second point in the generation step. The first point meets the condition, and the second point does not meet the condition. The processor displays the image on a display in the display step.
