A method of preparing biocompatible and stable gold nanoparticles comprises preparing at least one flavonoid-rich plant extract, and mixing at least one of the plant extracts with an aqueous solution of at least one gold salt. The flavonoid-rich plant extract is an extract of Hubertia ambavilla or Hypericum lanceolatum. The gold nanoparticles may be used for medical and/or cosmetic purposes.

The invention concerns a mixture or a composition, that is preferably therapeutically active by topical administration, comprising:at least one metal salt, the metal being chosen from molybdenum (Mo), tungsten (W), vanadium (V), gold (Au), a lanthanide, in particular lanthanum; at least one chelating agent; at least one source of peroxidative radicals; at least one buffer agent; and pharmaceutical compositions constituted by or comprising said mixture, the methods for producing same and applications thereof, in particular in a method for the therapeutic treatment of a viral infection, and in particular involving a virus of the Herpesviridae family; or as an anti-inflammatory.

The present invention provides compositions comprising energy (e.g., light) absorbing submicron particles (e.g., nanoparticles comprising a silica core and a gold shell) and methods for delivering such particles via topical application. This delivery is facilitated by application of mechanical agitation (e.g. massage), acoustic vibration in the range of 10 Hz-20 kHz, ultrasound, alternating suction and pressure, and microjets.

The present invention provides an immunomodulatory composition useful for treating or preventing joint damage comprising at least a set of peptides possessing an amino acid sequence having at least 80%, 85% and 90% sequence identity with the peptides corresponding to SEQ ID NO:1, SEQ ID NO:2, SEQ ID NO:3 and SEQ ID NO:4 and a method for the treatment or prevention of joint damage comprising the steps of a) extract monocytes from a patient with a rheumatological disease; b) culture the monocytes extracted in the previous step in AIM-V medium with GM-CSF and IL-4; c) wash the monocytes and add dexamethasone; d) load the tDCs with the immunomodulatory composition comprising autoantigenic peptides; e) add MPLA; and f) incorporate the tDCs loaded with autoantigenic peptides into the patient. The present invention includes methods for the treatment or prevention of rheumatological disease comprising a wide range of tDCs performed by different protocols.
