  • Patent number: 11684696
    Abstract: A gradient mineralized cancellous bone matrix material and a preparation method thereof are provided, and the preparation method includes: processing naturally-derived bone tissue with an immunogenicity removal treatment for decellularization, and processing an obtained decellularzed bone with a gradient demineralization treatment to obtain the gradient mineralized cancellous bone matrix material. The present invention expands a porosity of the bone matrix material and a collagen exposure degree on a surface thereof, which effectively releases growth factors and improves adhesion of the material to the cells, so as to up-regulate genes and proteins related to cell regeneration.
    Type: Grant
    Filed: March 12, 2019
    Date of Patent: June 27, 2023

  • Patent number: 9526013
    Abstract: The present invention provides a method and an apparatus for processing network configuration, and a radio network controller. The method includes: establishing a neighboring cell relationship between a macro cell and a generic access network cell, where the neighboring cell relationship is a neighboring cell mapping relationship between a radio network controller of the macro cell and a generic access network controller of the generic access network cell, and more than two generic access network cells share one generic access network controller; and when a handover of a user equipment from the macro cell to the generic access network cell occurs, sending a measurement control message to the user equipment according to the neighboring cell relationship between the macro cell and the generic access network cell.
