  • Patent number: 12144856
    Abstract: Miltefosine is utilized to enhance immune response to vaccination, for example an influenza and/or coronavirus vaccination. The inventive subject matter also provides compositions and methods for enhancing viral yield in cultured cells, by application of a cannabinoid receptor agonist (such as methanandamide) to such cells. Such enhanced viral yield can be used to enhance virus production for purposes of vaccine formulation and/or to improve sensitivity of cell-based virus assays.
    Type: Grant
    Filed: January 9, 2020
    Date of Patent: November 19, 2024
    Assignee: VERSITECH LIMITED
    Inventors: Kwok Yung Yuen, Kai Wang Kelvin To, Shuofeng Yuan, Fuk Woo Jasper Chan, Jinxia Zhang, Fan Ngai Hung, Johnson Yiu-Nam Lau
  • Patent number: 11357773
    Abstract: Compositions and methods are described in which the topical application of a toll-like receptor 7 agonist or a toll-like receptor 9 agonist at or near a subdermal vaccination site provides an enhanced response to the vaccination. The enhanced response can be an elevated antibody titer relative to an untreated but vaccinated subject, and/or development of cross-species immunity to species not present in the vaccinating composition.

  • Patent number: 9475067
    Abstract: The present invention relates to a mineral processing technology and method for refractory chalcopyrite ores, particularly to a mineral processing technology and method for the separation of chalcopyrite from multiple natural types of copper ores containing chalcopyrite, pyrrhotite, talc and serpentine, which belongs to the technical field of mineral processing. It's characterized by: conducting a two-stage grinding on the chalcopyrite ore, with each grinding stage followed by size grading, and treating ores in different size fractions separately, wherein coarse-grain ores are separated in the presence of xanthate, with calcium oxide and CMC controlling the pH and acting as depressor respectively, while fine-grained ores are subjected to rougher in the presence of kerosene, and subsequently subjected to cleaner in the presence of xanthate.
