  • Publication number: 20230214996
    Abstract: An eyes measurement system, a method and a computer-readable medium are provided, including a client device with a measurement application and a cloud processing device, where the cloud processing device receives the subject's eye images uploaded by the measurement application. After pre-processing the eye images, the cloud processing device uses a prediction model to obtain the predicted eye measure of the subject such as an MRD1, an MRD2 and an LF, and presents the predicted eye measure of the MRD1, the MRD2 and the LF to the clinicians as a basis for diagnosis. Therefore, the eye images are taken without restricting to the places, and the prediction model is used to accurately obtain the subject's eye measure, thereby providing the clinicians with a clear basis for diagnosis.

  • Publication number: 20220218758
    Abstract: The invention unexpectedly found that an isolated and modified QPSC population has multi-potentiality, including: osteoblasts (bone cells), chondrocytes (cartilage cells), and adipocytes (fat cells). The QPSC population of the invention features a desirable immunomodulation ability, including inducing, enhancing, or suppressing an immune response and thus has potential value in the prevention and/or treatment of various immune diseases/disorders/conditions. The invention has effective homing ability and regulation ability in complement-dependent cytotoxicity, including the ability to block the activation of host complements and direct migration to the target area and the ability to enhance cell viability, and thus offers better cell protection and therapeutic efficacy in vivo in the prevention and/or treatment of various acute tissue injury, ischemic or degenerative diseases/disorders/conditions.

  • Patent number: 9732323
    Abstract: The present invention describes an efficient and rapid protocol to generate hepatocyte cells from human induced pluripotent stem cells (iPSCs). According to the method, the iPS cells can be differentiated into functional hepatocyte cells in a short time course (less than 15-20 days). The iPSC-derived hepatocyte cells of the invention have a similar gene expression profile to mature hepatocytes. Moreover, the iPSC-derived hepatocyte cells is proved to rescue lethal fulminant hepatic failure in a non-obese diabetic severe combined immunodeficient mouse model. The rapid and efficient differentiation protocol for generation of iPSC-derived hepatocyte cells may offer an alternative option for treatment of liver diseases.
