摘要:
The present invention relates to a liquid lipid core/solid lipid shell capsule surface-functionalized with at least one compound containing at least one amino function, characterized in that the lipid core/lipid shell architecture is on the nanometric scale and in that said compound is covalently bonded to said solid lipid shell via a transacylation reaction. It also relates to a method for preparing such capsules.
摘要:
The present invention relates to a useful method for preparing nanocapsules with a liquid lipid core and a hard shell and loaded with at least one hydrophilic active agent, said method including at least the steps of: i) using at least one first water-in-oil microemulsion containing, in the hydrophilic phase thereof, at least one hydrophilic active agent; ii) using at least one second microemulsion that is formulated by the phase inversion of an emulsion; iii) adding said first microemulsion into said second microemulsion under conditions that are conducive to the formation of a novel microemulsion architecture wherein said hydrophilic active agent remains present in the hydrophilic phase of the first microemulsion; and iv) quenching the mixture that is formed in the preceding step so as to obtain microcapsules containing said hydrophilic active agent and being made of a lipid core that is liquid at room temperature and coated in a hard film at room temperature. The invention also relates to nanocapsules obtainable by said method.
摘要:
The present invention relates to a method for preparing poloxamer-protein particles. It also relates to poloxamer-protein particles obtainable by this method, dispersion thereof, and their use in methods of encapsulation, in particular of microencapsulation.
摘要:
The present invention concerns modified nucleobases, nucleosides, deoxynucleosides, and/or their derivatives, nanocapsules comprising them, hydrogels and oleogels comprising said nanocapsules or said above-mentioned compounds and their uses, in particular their pharmaceutical uses.
摘要:
The present invention relates to nanocapsules, including: a core essentially consisting of a fatty substance, which is liquid or semi-liquid at ambient temperature, and including a hydrophobic active principle and a diethylene glycol ether; an outer lipid shell which is solid at ambient temperature. The lipid nanocapsules of the invention are intended in particular for the manufacture of a drug.
摘要:
Use of a colloidal carrier for the manufacture of a medicament for inhibiting P-glycoprotein, wherein said colloidal carrier: - encapsulates or adsorbs a pharmacologically active substance, and - comprises P-glycoprotein inhibitor surfactants bound to the colloidal carrier surface.
摘要:
The invention relates to nanocapsules with a liquid lipidic core and a solid lipidic shell, the lipidic core being loaded with at least one water-soluble or water-dispersible ingredient, said ingredient being present in the form of a reverse micellar system.
摘要:
The invention relates to a filament comprising thermoluminescent particles that are evenly distributed in a polymer matrix, characterized in that the polymer matrix is a thermoplastic polymer having sufficient adhesion with respect to said thermoluminescent particles in order to ensure the cohesion of said filament and being such that the thermoluminescent response (signal) of the filament corresponds substantially to the dose of radiation absorbed and obtained after the filament is placed in contact with a physiological medium. The invention also relates to a method for thermoluminescence-based measurement of doses of beta radiation delivered by a transmitter on a target organ of a mammal, characterized in that a group of inventive filaments is introduced to the desired spot, whereby part of the length of said filaments remains outside the irradiated area, and in that the filaments are removed after irradiation and thermoluminescence is determined.
