Heat substrate and/or image enhancement compositions and enhanced tissue ablation methods
Ferritin or iron-based image enhancement agents identify target tissue for treatment or ablation and are heated by microwave absorption. Microwave heat substrates enhance microwave hyperthermal ablation treatment, and may be percutaneously delivered and imaged by x-ray CT during placement of the microwave treatment antenna, allowing more precise positioning and more complete ablation of a tumor site. One method of treating a target tissue uses image-guided delivery of a heat substrate with a reverse-phase change polymer, and may apply energy to fix a mass of the material in the tissue. The fixed polymer may increase hyperthermia, form a thermal boundary, or blockade a vessel or passage so as to reduce or prevent undesired conductive cooling by contiguous tissue, or may deliver a localized treatment drug at the site, upon heating or as it degrades over time.
Nuclear spin hyperpolarization in a porous matrix
A method of enhancing the nuclear spin polarization of target molecules (10) uses a hyperpolarized source material (12) that is co-confined with the target molecules (10) in a porous molecular matrix (20). The matrix (20) may be a D4R-polysiloxane copolymer such as polyoligosiloxysilicone number two (PSS-2) that has recesses of an appropriate diameter. A source material (12), such as parahydrogen, is transferred to the matrix (20) together with the target molecules (10), and an external pressure is applied to force them into the recesses of the matrix (20). The nano-confinement of the source material (12) and target molecules (10) together enables or enhances a transfer of spin polarization from the source material (12) to the target molecules (10). When the target molecules (10) are removed from the matrix (20), the enhanced spin polarization greatly enhances the signal strength of the target molecules (10) in any subsequent magnetic resonance measurement.
METHOD FOR TREATING BREAST CANCER WITH A CHEMOTHERAPEUTIC DRUG CARRIER
Silica nanocarriers hybridized with superparamagnetic iron oxide nanoparticles (“SPIONs”) and curcumin through equilibrium or enforced adsorption technique. Methods for dual delivery of SPIONs and curcumin to a target for diagnosis or therapy, for example, for SPION-based magnetic resonance imaging or for targeted delivery of curcumin to a cell or tissue. The technique can be extend to co-precipitation of mixed metal oxide involving Ni, Mn, Co and Cu oxide. The calcination temperature can be varied from 500-900° C. The nanocombination is functionalized with chitosan, polyacrylic acid, PLGA or another agent to increase its biocompatibility in vivo.
