摘要:
The present invention relates to the use of an active substance that promotes the inhibition of the formation of AGEs, for preparing a composition to prevent and/or combat the reduction in elastic and plastic properties of tissues, and in particular of the skin, for inhibiting the formation of AGEs, or for preventing and/or combating glycation of proteins in the skin.The invention also relates to a method of screening such active substances.
摘要:
The present invention relates to a method for preparing Langerhans cells or interstitial dendritic cells, or both, from CD14+ monocytes stemming from the peripheral circulatory blood of a living being, wherein the method comprises differentiation of CD14+ monocytes into either Langerhans cells, interstitial dendritic cells, or into both types of cells by placing the CD14+ monocytes in the presence of a cell environment comprising epithelial cells and/or mesenchymatous cells.The present invention also relates to cell or tissue models comprising such prepared Langerhans cells and/or interstitial dendritic cells, and optionally macrophages and endothelial cells, and to the uses of such cell or tissue models.
摘要:
The invention discloses a method for tinting, for coloring skin, or for increasing the tanned appearance of skin comprising the use of an extract of a plant from the family of Compositae or Asteraceae, preferably an extract of chicory (Cichorium intybus L.), and a method of screening a plant for the manufacture of a cosmetic composition for coloring, particularly for tinting, at least one part of skin.
摘要:
Germinated plant seeds are disclosed as a source of superoxide dismutase (SOD). The SOD is stabilized to temperatures of at least 45.degree. C. when combined in a stabilizing composition comprising a peroxidase, a peroxidase cofactor, and a hydrophilic substance selected from sugars and polyols of less than 2,000 g/mole in molecular mass. The stabilized SOD compositions can be used in cosmetic, pharmaceutical or food compositions. Methods of treating mammals against the harmful effects of free radicals and against inflammation are also disclosed.
摘要:
The invention relates to new lipophilic hydroxylated acids wherein said lipophilic hydroxylated acid comprises a hydrophobic hydrocarbon chain having from 7 to 30 carbon atoms grafted onto the hydroxyl functional group and/or the acid functional group of the lipophilic hydroxylated acid via a covalent bond chosen from the group consisting of an ester bond on the hydroxyl functional group, an anhydride bond on the acid functional group and an amide bond on the acid functional group, provided that, in the case of an amide bond, this hydrophobic hydrocarbon chain consists of an alkyl radical having from 10 to 30 carbon atoms resulting from a monoamine, or a combination of these bonds. These new derivatives are useful as active ingredient of cosmetic or pharmaceutical compositions and as emulsifying agents.
摘要:
The method for producing microparticles is characterized in that it comprises the following steps: preparation of an emulsion of a solution of a substance or a mixture of substances in a dispersing liquid wherein said substance or said mixture are substantially insoluble; incorporating to said dispersed phase a chemical agent substantially insoluble in the dispersing liquid so as to cause within the dispersed phase a chemical or physicochemical reaction responsible for the formation of microparticles which are then isolated.
摘要:
The subject of the invention is the use of an extract of Stevia in combination with a salt, for masking the bitterness of bitter compounds in cosmetic or dermatological compositions.This mixture of sweetener with a second gustatory agent makes it possible to mask the bitterness of the compound permanently without changing the nature of the fragrance or the colour of the composition.
摘要:
The invention relates to methods useful in studying or modulating skin or hair pigmentation and to the use of plant extracts in compositions as well as to methods comprising the topical use of such compositions to reduce or to enhance skin or hair pigmentation.
摘要:
The invention relates to the stimulation of the synthesis and of the activity of an isoform of lysyl oxidase, and more particularly of the LOXL (lysyl oxidase-like) isoform. The invention relates notably to a method of identifying an active principle which stimulates the formation of elastic fibers. The aim of the invention is mainly to provide such a method of identification so as to provide compositions which enable stimulating the formation of elastic fibers.
