Abstract: A non-human gene-edited mammal, a protein crude extract isolated from a connective tissue of the non-human gene-edited mammal, a method for preparing the protein crude extract, and uses of the protein crude extract are provided. The method includes: microinjecting a deoxyribonucleic acid sequence construct (DNA construct) containing SEQ ID NO: 4 or SEQ ID NO: 5 into a rat embryo, transplanting the rat embryo into a female rat of the same species to develop into a mature rat, and isolating a protein crude extract from a connective tissue of the mature rat. The protein crude extract includes human type I collagen and a non-native chimeric protein peptide chain.

Abstract: The present invention features a method for reducing the damage caused by free radicals, the method comprises administering a pharmaceutical composition that comprises at least a metal or its ions, at least a drug or an antioxidant that is carrier-protected/modified, and a drug carrier to a subject. Said carrier helps to preserve the anti-oxidative activity, and hence, prevents the decrease of the effect of the antioxidant against free radicals produced in the environment or body fluids and prolongs protection, and be used for reducing damage caused by radiation and adverse effects induced by chemotherapeutic drugs.

Abstract: This invention provides the controlled-release method for a pharmaceutical composition comprising of metals in the drug carrier. The specific chelator is used to trigger the release of active pharmaceutical ingredients from chelating complex micelles. The drug release rate and half-life can also be controlled by manipulating the dosing sequence and the concentration of metal and specific chelator.
