  • Patent number: 10166104
    Abstract: A bone-repair composite includes a core and a sheath. The core is a first primary unit including a combination of a first set of yarns coated with a calcium phosphate mineral layer. The first set of yarns being made from a first group of one or more polymers. The sheath is a second primary unit a combination of a second set of yarns or one or more polymer coatings. The second set of yarns being made from a second group of one or more polymers, wherein the composite is made by covering the core with the sheath, and the composite is compression molded to allow the sheath to bond to the core. The bone-repair composite has a bending modulus comparable to that of a mammalian bone, such that the ratio of the core to the sheath is provided to maximize the mechanical strength of the bone-repair composite to mimic the mammalian bone.

  • Publication number: 20140161779
    Abstract: Involved is a method for controlling the pest Sesamia inferens, comprising a step of contacting Sesamia inferens with Cry1F protein. Sesamia inferens is controlled by the Cry1F protein having pesticidal activity against Sesamia inferens, which is produced in the plants. Compared with the agricultural control, chemical control and biology control currently used in prior art, the present invention can protect the whole plant during whole growth period from the harm of Sesamia inferen. Furthermore, it causes no pollution and no residue and provides a stable and thorough control effect. Also it is simple, convenient and economic.
