The present invention provides stem cells loaded with bi-functional magnetic nanoparticles (nanoparticle-loaded stem cells (NLSC)) that both: a) heat in an alternating magnetic field (AMF); and b) provide MRI contrast enhancement for MR-guided hyperthermia. The nanoparticles in the NLSC are non-toxic, and do not alter stem cell proliferation and differentiation, the nanoparticles do however, become heated in an alternating magnetic field, enabling therapeutic applications for cancer treatment. NLSC can deliver hyperthermia to hypoxic areas in tumors for sensitization of those areas to subsequent treatment, thus delivering therapy to the most treatment-resistant tumor regions. The heating of diseased tissue either results in direct cell killing or makes the tumor more susceptible to radio- and/or chemotherapy. The NLSC of the present invention can be used for MR image-guided hyperthermia in oncology, in stem cell research for cell tracking and heating, and for elimination of mis-injected stem cells.

Amorphous Medicinal Fine Particles Produced By Pulsed Laser Ablation In Liquid And The Production Method Thereof

Номер: US20130209523A1
Принадлежит: IMRA America Inc

The present disclosure is directed to an in-liquid laser-based method for fabricating a solution of fine particles of amorphous solid medicinal compounds, a solution of fine particles of amorphous medicinal agents made with the method, and fine particles made with the method. By using a target solidified via a phase transition process to covert an initial crystalline structure into an amorphous solid, technical difficulties with handling a hydraulically-pressed target are overcome. The laser-based ablation process produces amorphous solid medicinal compound fine particles, which improves the bioavailability and solubility of the medicinal compound. The improvement results from a combination of: disordered crystalline structure and enlarged relative surface area by particle size reduction. The laser based method may be carried out with ultrashort pulsed laser systems, or with UV nanosecond lasers. Results obtained with an ultrashort near IR laser and a UV nanosecond laser show formation of amorphous solid curcumin fine particles.
