Abstract: The present invention relates to the cosmetic use by the topical route of a Tapirira guianensis extract, for stimulating the expression of perlecan and/or dystroglycan and/or VE-cadherin and/or claudin-5, in particular in the extracellular matrix and/or in the epithelial basement membrane, especially the dermoepidermal junction. It also relates to a cosmetic care method comprising the application, to at least one concerned area of healthy skin and/or healthy mucous membrane and/or healthy scalp, of a Tapirire guianensis extract or of a cosmetic composition comprising such an extract for stimulating the expression of perlecan and/or dystroglycan and/or VE-cadherin and/or claudin-5, in particular in the extracellular matrix and/or in the epithelial basement membrane, especially the dermoepidermal junction. In addition, it relates to a cosmetic composition comprising a Tapirira guianensis extract and a topically acceptable cosmetic excipient.

Abstract: The present invention relates to the topical cosmetic use of a Polygonum bistorta extract for stimulating the expression of perlecan and/or dystroglycan, in particular in the extracellular matrix and/or in the epithelial basement membrane, especially the dermoepidermal junction. It also relates to a cosmetic care method comprising the application, to at least one concerned area of healthy skin and/or healthy mucous membrane and/or healthy scalp, of a Polygonum bistorta extract or of a cosmetic composition comprising such an extract for stimulating the expression of perlecan and of dystroglycan, in particular in the extracellular matrix and/or in the epithelial basement membrane, especially the dermoepidermal junction.

Abstract: The invention concerns an assembly for fixing two thermally non-expansible thermoplastic tubular elements (1, 2) characterized in that it comprises a first thermally non-expansible thermoplastic tubular element (1) including a fixing zone (4) on the inner wall of one of its ends, a second thermally non-expansible thermoplastic tubular element including a fixing zone (6) on the outer wall of one of its ends, the diameter of the inner wall of said end of the first tubular element (1) being larger than the diameter of the outer wall of said end of the second tubular element (2) so as to define, when the two ends overlap, an annular space between said inner and outer walls, the assembly further comprising a thermoplastic sleeve (3) adapted to be housed in the annular space, said sleeve (3) containing a conductive element (5) capable of being induction-heated.

Abstract: The present invention provides methods for isolating adjunct isoforms of proteins and converting them to the desired protein. In preferred embodiments, the present invention contemplates the use of acid solutions or zinc solutions to cleave a chemical group from a desired protein. In further preferred embodiments, the present invention contemplates the oxidation of reduced sulfhydryl groups with cleavage of chemical groups to form a functional desired protein.
