Abstract: A controlled-release fertilizer including an inside core of water-soluble fertilizer particle and an outer layer coating material, wherein the coating material is a bentonite modified or sodium bentonite modified waterborne polymer; and a preparation method including: weighing the fertilizer core particle and the modified waterborne polymer emulsion according to the amount, preparing a semi-processed coating controlled-release fertilizer by using a coating machine, and placing the semi-processed coating controlled-release fertilizer in an oven for postprocessing to improve the compactness of the film material.

Abstract: The present application relates to a lipopeptide for potently inhibiting HIV, a derivative thereof, or a pharmaceutical composition thereof, and use thereof. The lipopeptide is the following a) or b): a) a lipopeptide formed by linking a polypeptide having an antiviral activity to a lipophilic compound linked to the carboxyl-terminus of the polypeptide; or b) a lipopeptide formed by linking a polypeptide having an antiviral activity to a terminal protecting group and a lipophilic compound linked to the carboxyl-terminus of the polypeptide, wherein the terminal protecting group is an amino-terminal protecting group and/or a carboxyl-terminal protecting group, the polypeptide has a sequence of 28 amino acid residues, corresponding to amino acids at positions of 127-154 of the sequence of gp41 from HIV-1 strain HXB2.

Abstract: The present invention provides an isolated antibody capable of binding to the receptor-binding domain of the spike protein of the severe acute respiratory syndrome-associated coronavirus (SARS-CoV) so as to competitively inhibit the binding of the SARS-CoV to host cells. These mAbs or substances can be used: 1) as passive-immunizing agents for prevention of SARS-CoV infection; 2) as biological reagents for diagnosis of SARS-CoV infection; 3) as immunotherapeutics for early treatment of SARS-CoV infection; and 4) as probes for studying the immunogenicity, antigenicity, structure, and function of the SARS-CoV S protein.
