Abstract: The present invention relates to acrylic hydrogels functionalized with cyclodextrin that comprises ?-lipoic acid, to methods for obtaining said hydrogels, and to the use of contact lenses prepared from said hydrogels as demulcent agents.

Abstract: The invention relates to acrylic hydrogels with pendant cyclodextrins, the preparation and application thereof as release systems and components of contact lenses. The method for obtaining acrylic hydrogels with pendant cyclodextrins is characterized in that the hydrogels are formed by a polymer lattice obtained by polymerization of mono- and bifunctional acrylic or methacrylic monomers and monomers having glycidyl groups in their structure, to which cyclodextrin units are covalently bound once formed; and the use and applications of the compositions in the preparation of contact lenses with the capacity for incorporating drugs, active substances or demulcents useful in the treatment of pathological or physiological conditions, in the production of topical, transdermal or transmucosal release systems for medicinal products or active substances, and in the preparation of cosmetics.

Abstract: The invention describes for first time the activity of poloxamines as inducers in the differentiation of mesenchymal or progenitor cells. In particular, the invention demonstrates that poloxamines have an osteogenic ability. The invention relates to the use of one or more poloxamines or a pharmaceutical composition comprising same for the preparation of a drug for treting patients with bone defects in general. The invention also relates to a method for inducing the differentiation of mesenchymal or progenitor cells into osteoblasts by bringing said cells into contact with a sterilised aqueous dispersion or solution of one or more poloxamines.

Abstract: The invention relates to a method of obtaining hydrogels based on (i) cyclodextrins, (ii) cyclodextrins and cellulose ethers or (iii) cyclodextrins and guar gum or the derivatives of same, using molecules containing two or more glycidyl ether groups in the structure thereof as a cross-linking agent. The invention also relates to the compositions thus obtained, which can include active substances and pharmaceuticals and which form inclusion complexes with cyclodextrins. The invention further relates to the use of same as components of controlled-release devices, such as transdermal pharmaceutical forms, vaginal, otic, ocular, rectal, oral or buccal transmucosal forms and parenteral implants, which are designed to administer active substances or pharmaceuticals to humans, animals or plants, or as components of cosmetic formulations.
