  • Publication number: 20240231125
    Abstract: A double-sided composite spectacle lens and an inject mold therefor are provided. One surface of the spectacle lens is an aspherical surface, and the other surface is a designed aspherical surface used to inhibit astigmatism, and a spectacle lens formed by combining the two surfaces has two areas with different functions: optimizing optical performance, and thinning for aesthetics. By controlling the reduction of diopter and optimizing astigmatism on one surface, and inversely offsetting astigmatism on the other surface, the degree of astigmatism of the spectacle lens formed by combining the two surfaces is significantly lower than a diopter variation, and the degree of oblique astigmatism is significantly reduced. The aesthetic thinning effects of reducing the edge or center thickness of the double-sided composite spectacle lens are significantly enhanced by accelerating reduction of the diopter on one surface and changing from reducing to increasing the diopter on the other surface.

  • Patent number: 11987797
    Abstract: The present disclosure belongs to the technical field of biology, and in particular relates to an attenuated strain of African swine fever virus (ASFV) with IPTG-induced deletion of a D1133L gene and use thereof. In the present disclosure, it is firstly found that the D1133L protein of ASFV can inhibit production of IFN-? and downstream cytokines ISG-15 and ISG-56, and can be used as an immunosuppressant with a relatively strong immunosuppressive effect. In addition, the attenuated strain of ASFV with IPTG-induced deletion of the D1133L gene is constructed. Specifically, a screening expression cassette is inserted into a position before the non-structural protein gene D1133L of the ASFV using an Escherichia coli lac operator-repressor system, to obtain a recombinant virus. In the presence of the IPTG, the recombinant virus has similar characteristics to a wild-type virus; and in the absence of the IPTG, the expression of the D1133L protein is inhibited.
