摘要:
A preparation for vaginal and rectal use comprising hyaluronic acid, with an average particle size comprised between about 50 micrometers and about 200 micrometers and a molecular weight comprised between about 1,000,000 Da and about 1,800,000 Da.
摘要:
The present invention relates to a controlled release pharmaceutical or food formulation comprising at least one active pharmaceutical or food ingredient dispersed in a mixture of a glycogen with a polysaccharide, and the process for its preparation. The invention also relates to a slow release system represented by a mixture of a glycogen with a polysaccharide, and its use for the preparation of slow release pharmaceutical or food formulations.
摘要:
The invention relates to the discovery that human and murine tumors release LXR ligands (oxysterols) that inhibit CCR7 expression on maturing DC and, therefore, their migration to lymphoid organs. By inhibiting oxysterol synthesis (by Zaragozic Acid, ZA) or by inactivating oxysterols (gene therapy with sulfotransferase SULT2B1 b enzyme) long lasting antigen specific anti-tumor immune response mediated by DC is increased. Surprisingly, we also show that drugs interfering with sterol metabolism (i.e. ZA) in combination with a mAb depleting T regulatory cells potentiate the antitumor effect of the single treatments. This synergic effect is unexpected, providing a new effective combination therapy for the treatment of cancer. The invention also relates to the novel use of LXR ligand inactivators, or of LXR inhibitors/antagonists, for the treatment of cancer. These strategies can also be used in combination with a chemotherapy approach for the treatment of cancer patients.
摘要:

摘要:
The present invention relates to microparticulate systems consisting of a gastroresistant, biocompatible and biodegradable polymer matrix, comprising a gastroresistant and enterosoluble polymer, a cryoprotector or lyoprotector, a divalent or trivalent metal salt of i biocompatible and biodegradable polymer having acid groups, and biologically active substances. Such gastroresistant microparticulate systems are used for the administration, preferably oral, of biologically active substances to animal species. The special composition of such microparticulate systems allows the protection of said biologically active substances from degradation by proteases and gastric acid, allowing their release into the intestine, where they may perform their activities.
摘要:
A process for encapsulating and immobilising mammalian stem cells, ovarian follicular cells, gametes, ovarian follicles or mammalian embryos which are able to auto-organise into three-dimensional structures in vitro, and express biological functions in a manner similar to that which is observed in the organism in vivo is described. The capsules are constituted by: a nucleus containing stem cells, ovarian follicular cells, gametes, ovarian follicles or mammalian embryos and/or a biocompatible and/or biodegradable polymer; a semi-permeable membrane constituted by a divalent or trivalent metal ion salt of alginic acid, optionally cross-linked on the inner and/or outer surface and/or on both surfaces, optionally vehicularising a second or more cellular species. The cells and follicles prepared and cultivated using this methodology are used for the in vitro and/or in vivo production of peptides, proteins, antibodies, hormones and hormone precursors, metabolites and catabolites typical of these cellular structures, plasma membranes, nuclear membranes, cytoplasmic organelles, somatic cell nuclei or gametes and embryos.
