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.

Abstract: The present disclosure belongs to the technical field of African swine fever (ASF) treatment, in particular to use of a compound aprepitant in prevention or treatment of the ASF. In the present disclosure, it is found that the compound aprepitant can significantly inhibit replication of an African swine fever virus (ASFV); in addition, it is found that the aprepitant inhibits transcription and protein expression of D1133L, and reduces transcription and protein expression levels of p30 and p72, preventing virus invasion on host cells. Therefore, the compound aprepitant can be used to inhibit early and late infection of the ASFV. Accordingly, the compound aprepitant can be used to prevent or treat the ASF.

Abstract: Embodiments allow, within database security policies, the grant of data change operation-specific privileges to particular users to be applied within particular data realms in a given table. Furthermore, according to one or more embodiments, User Privilege column-level privileges are explicitly associated with one or more data access operations such that the grant of such a column-level privilege allows the user to perform only those data access operations that are explicitly associated with the column-level privilege. Enforcement of the data security policies includes prevention of data leakage via WHERE and RETURNING INTO clauses. According to one or more embodiments, a two-phase rewrite is used to optimize enforcement of column-level privileges. During the two-phase rewrite of a given query, the privileges checked during enforcement of the User Privilege data security policies are pruned to avoid unnecessary privilege checks given the columns that are accessed in the query.
