Molecular complexes and compositions containing the same are disclosed herein. More specifically, carbohydrate polymers, for example hyaluronic acid or a salt thereof, are complexed with a biologically active compound selected from natural products and nutrients (amino acids, amino esters, hydroxy acids, hydroxy esters, vitamins, cannabinoids, etc.), and active pharmaceutical ingredients to create stabilized molecular complexes. The complexation can be conveniently achieved by means of a resonant acoustic mixing process.

A method of enhancing penetration of a topical composition of 5-aminolevulinic acid (ALA) into tissue for photodynamic therapy includes topically applying ALA to a treatment area to be treated with photodynamic therapy. The method further includes, after the ALA is applied to the treatment area, covering the treatment area with a low density polyethylene barrier. The treatment area is covered with the low density polyethylene barrier prior to light treatment to minimize transepidermal water loss from the treatment area.

Methods of making and using a magnetic ECM are disclosed. The ECM comprises positively and negatively charged nanoparticles, wherein one of said nanoparticles contains a magnetically responsive element. When the magnetic ECM is seeded with cells, the cells will be magnetized and can be levitated for 3-D cell culture.

A silybin injection contains silybin, sulfobutyl ether-β-cyclodextrin, an organic solvent for injection and may further contain a co-solvent, a lyophilization proppant, a pH regulator, water for injection and the like.

A method of forming an implant in the tissue can include: providing an injectable composition having a neat liquid carrier, wherein the neat liquid carrier is substantially liquid at room temperature and/or about body temperature; and injecting the neat liquid solution into the tissue at the rate of 10-12000 injections per minute and/or at an amount of 1.0E-02 ml to 1.0E-16 ml per needle per injection. The neat liquid carrier can be polymeric or non-polymeric. The neat liquid carrier can be biodegradable. The neat liquid carrier can include a viscosity-modifying agent. The injecting can form an implant with area greater than or equal to 5 mm.sup.2. The neat liquid carrier can be injected at a depth of 10 microns to 5 mm. The neat liquid solution can include a drug or other agent.

The invention relates to novel biocompatible hybrid nanoparticles of very small size, useful in particular for diagnostics and/or therapy.

The purpose of the invention is to offer novel nanoparticles which are useful in particular as contrast agents in imaging (e.g. MRI) and/or in other diagnostic techniques and/or as therapeutic agents, which give better performance than the known nanoparticles of the same type and which combine both a small size (for example less than 20 nm) and a high loading with metals (e.g. rare earths), in particular so as to have, in imaging (e.g. MRI), strong intensification and a correct response (increased relaxivity) at high frequencies. The method for the production of these nanoparticles and the applications thereof in imaging and in therapy also form part of the invention.

Use of 10H-benzo[g]pteridine-2,4-dione derivatives as photosensitizers in the inactivation of microorganisms.

Autologous anti-cancer vaccines and methods of manufacture and treatment are provided, including expansion of individual patient-derived tumor cells in an immune-compromised animal(s) to attain, quantitatively and qualitatively, sufficient material for efficacious vaccine production and utilization, to elicit an immune response against micrometastases and/or recurrence in the individual patient following tumor excision.

The invention discloses a composition comprising surface modified iron oxide nanoparticles with citric acid modified cyclodextrin with a hydrodynamic diameter of less than 10 nm and a hydrophobic molecule.

The composition finds use in targeted delivery of a hydrophobic drug and as contrast agent in imaging applications.
