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 invention relates to small sized particles.These particles comprise at least on the surface thereof a wall composed of a mixture of at least one protein and at least one polysaccharide which are cross-linked, preferably by interfacial cross-linking with a polyfunctional acylating agent which forms at least amide and ester bonds, and optionally anhydride bonds with amine, hydroxyl or carboxyl functions of the protein and of the polysaccharide, and which comprise hydroxamic groups on the surface thereof for chelating metal ions.These particles can be used in cosmetics or in pharmacy notably for the chelation or release of metal ions.
摘要:
Particles comprising an outer wall formed of one or more saccharide components selected from the group consisting of monosaccharides and oligosaccharides crosslinked by interfacial crosslinking in emulsion, preferably at room temperature, with a polyfunctional acylating crosslinking agent to produce ester linkages between the acylatable hydroxyl group(s) of the primary alcohol(s) of the saccharide component and the acyl groups of the polyfunctional acylating agent. These particles can be used for the manufacture of cosmetic, pharmaceutical and food compositions.
摘要:
The invention relates to particles. These particles comprise, at least on the surface, a wall formed of plant proteins crosslinked particularly by means of interfacial crosslinking between the plant proteins and an acylating polyfunctional crosslinking agent comprising at least two acylating groups, covalent bonds being formed between the acylatable groups of the proteins and the acyl groups of the acylating polyfunctional crosslinking agent. These particles are used for the manufacture of a cosmetic, pharmaceutical, dermatological or food composition.
摘要:
The invention relates to substances which are capable of protecting FGF-2, to a composition for preventing or controlling degradation of FGF-2, and a method of protecting FGF-2 in the skin from degradation.In particular, the invention relates to an extract of Hibiscus Abelmoschus or ambrette, a rebokza extract, a gougizi berry extract, a banha extract, a lessonia extract, a mustard flour extract, a wooyin extract, a barley extract, and/or a sesame extract, in amounts effective to protect FGF-2 from its degradation.Further, the present invention allows the extracellular matrix to be restructured, particularly at the dermis, which is useful, for example, for controlling aging.
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 disclosed substance restores normal co-expression and interaction between the LOX and NRAGE proteins. Particularly, an effective amount of the substance that modulates the expression and/or activity of LOX of SEQ ID NO: 1 and/or that modulates the expression and/or activity of NRAGE of SEQ ID NO: 2, may be used for the manufacture of a composition for modulating the interaction between the LOX and NRAGE proteins to regulate the balance between the cellular phenomena of proliferation, differentiation and apoptosis, particularly in cases where the balance between these phenomena is disturbed, and especially in cases where the interaction between LOX and NRAGE is absent or altered. The invention makes it possible especially to treat and/or prevent skin ageing, lichen planus, graft-versus-host reaction (GVH), eczema, psoriasis and a cancer, particularly an epithelial cancer and more particularly a cutaneous epithelial cancer of basocellular or spinocellular type.

摘要:
The invention relates to a substance for restoring normal co-expression and interaction between the LOX and NRAGE proteins.The invention relates in particular to the use of an effective amount of at least one substance that modulates the expression and/or activity of LOX of sequence ID no. 1, and/or that modulates the expression and/or activity of NRAGE of sequence ID no. 2, for the manufacture of a composition for modulating the interaction between the LOX and NRAGE proteins in order to regulate the balance between the cellular phenomena of proliferation, differentiation and apoptosis, particularly in cases where the balance between these phenomena is disturbed, and especially in cases where the interaction between LOX and NRAGE is absent or altered.The invention makes it possible especially to treat and/or prevent skin ageing, lichen planus, graft-versus-host reaction (GVH), eczema, psoriasis and a cancer, particularly an epithelial cancer and more particularly a cutaneous epithelial cancer, of basocellular or spinocellular type.
摘要:
The invention concerns active substances modulating the expression of the receptors of the products of the POMC gene (MC-IR, MC-2R, and the μ opioid receptor), and possibly modulating the expression of POMC in cutaneous cells, notably to modulate the proliferation and differentiation of epidermal cells in order to re-epithelial, maintain innervation, irrigate the skin, or to fight against aging, or to modulate pigmentation independently or not of cutaneous aging. The invention also concerns a method of screening such active substances.
