权利人:NEWSOUTH INNOVATIONS PTY LTD
摘要:The present disclosure relates to the field of synthesis of block copolymers, and polymeric nanofibers having a core-shell morphology produced therefrom. The present disclosure relates to the field of synthesis of block copolymers where one block is more hydrophobic than the other block and is a different composition. The disclosure also relates to uses of these polymeric nanofibers in various applications, such as reinforcing a polymeric matrix and for coatings applications.

摘要:A cosmetic including two different systems for procurement of actives in the human skin and enhancing the collagen I synthesis. The cosmetic with enhanced collagen I synthesis can include 0.001 to 2% by weight, related to the total weight of the cosmetic, of a first retinol-containing system including retinol encapsulated in a chitosan and carboxymethyl cellulose shell, 0.001 to 3.5% by weight, related to the total weight of the cosmetic, of a second retinol-containing system including cationic liposomes composed of phospholipids and with a quaternary fatty acid monoamine with C 21 -C 23 alkyl residue and the difference to 100% by weight of cosmetic subsidiaries. Very small amounts of retinol in combination with both transport systems show a remarkable effect on the synthesis of collagen I in comparison with one or more other known combinations of retinol derivatives or encapsulated systems.

标题:Compositions for reducing UV-induced inhibition of collagen biosynthesis in human skin
发明人：FISHER GARY J; VOORHEES JOHN J
权利人:UNIV MICHIGAN
摘要:Exposure of human skin to ultraviolet (UV) radiation from the sun not only induces the production of enzymes (matrix metalloproteinases) that degrade collagen, but also inhibits the synthesis of new collagen by inhibiting the synthesis of procollagen. This UV-induced inhibition of the synthesis of collagen can be prevented by the topical application of a retinoid or c-JUN inhibitor to the skin prior to exposure to UV radiation.
