    摘要: The invention relates to a polyoxometalate topical composition for removing a contaminant from an environment, comprising a topical carrier and at least one polyoxometalate, with the proviso that the polyoxometalate is not H5PV2Mo10O40; K5Si(H2O)MnIIIW11O39; K4Si(H2O)MnIVW11O39; or K5CoIIIW12O40. The invention further relates to a method for removing a contaminant from an environment, comprising contacting the polyoxometalate topical composition of the present invention with the environment containing the contaminant for a sufficient time to remove the contaminant from the environment. The invention further relates to a method for removing a contaminant from an environment, comprising contacting a polyoxometalate powder or a polyoxometalate coating with the environment containing the contaminant for a sufficient time to remove the contaminant from the environment. The invention further relates to a modified polyoxometalate, wherein the modified polyoxometalate comprises the admixture of (1) a polyoxometalate and (2) a cerium compound, a silver compound, a gold compound, a platinum compound, or a combination thereof. The invention further relates to a method for removing a contaminant from an environment, comprising contacting a modified material with the environment containing the contaminant for a sufficient time to remove the contaminant from the environment, wherein the modified material comprises (1) a material and (2) a metal compound comprising a transition metal compound, an actinide compound, a lanthanide compound, or a combination thereof, wherein the metal compound is not a polyoxometalate. The invention further relates to a modified material for removing a contaminant from an environment, wherein the modified material comprises (1) a material comprising a topical carrier, a powder, a coating, or a fabric, and (2) a metal compound comprising a transition metal compound, an actinide compound, a lanthanide compound, or a combination thereof, wherein the metal compound is not a polyoxometalate. The invention further relates to an article comprising the modified material of the present invention.

    摘要: A method of improving DNA repair and reducing DNA damage and for reducing mutation frequency in skin for the purpose of reducing consequences of exposure to solar or ultraviolet radiation is disclosed. The methods comprise administering to the skin a composition containing deoxyribonucleosides in concentrations sufficient to enhance DNA repair or reduce mutation frequency in a vehicle capable of delivering effective amounts of deoxyribonucleosides to the necessary skin cells.
