  • Patent number: 11214917
    Abstract: The present invention relates to a method of obtaining a solid material based on a polymer having its cellobiose units exhibiting the following characteristics: at least some of the cellobiose units have at least one carboxylic acid function attached to the C6 carbon, the other C6 carbons having a primary alcohol function attached thereto; and at least some of the cellobiose units have at least one of the two rings open between the C2 and C3 carbons, the other C2 and C3 carbons forming a ring and having an alcohol function attached thereto. Such a material, advantageously a textile, may be used as a compress.

  • Patent number: 9260507
    Abstract: A peptide is provided with a defined sequence present in the alpha3 chain of the LG4 globule of laminin 332 (laminin 5), and peptides with sequences homologous to the peptide with the defined sequence capable of binding to the syndecan-1 receptor. Pharmaceutical or cosmetic compositions containing the peptide are provided. The peptide is used in the area of tissue healing and regeneration or as an adjuvant in culture media intended for epidermal or epithelial reconstruction. The synthetic peptide comprises the sequence KKLRIKSKEK (SEQ ID NO: 1) or a sequence of identical size, in which the K residue (in position 1) and the R residue (in position 4) are conserved, the sequence being able to bind to the syndecan-1 receptor.

  • Publication number: 20130123683
    Abstract: A device includes a hollow body delimiting a cavity for receiving the fluid, which cavity opens in a proximal opening and at least one distal opening for sampling and/or reinjection and a piston movably mounted in the receiving cavity to obturate the proximal opening. The device includes an assembly for selective distribution of a proximal part of the fluid located in the receiving cavity, including a fluid circulation channel that passes through the piston, which channel opens into the receiving cavity. The circulation channel and/or a distribution channel is able to cooperate or to communicate with an additional flow regulation device which can be manually actionable.
