REMOTELY TRIGGERED THERAPY
This disclosure provides particles that are suitable for remotely-triggered therapy for cancer and microbial infection. In an embodiment, this disclosure provides a particle heater comprising a carrier admixed with a material that interacts with an exogenous source; wherein the material absorbs and converts the energy from the exogenous source into heat, then the heat travels outside the particle heater to induce localized hyperthermia at a temperature sufficient to selectively kill unwanted cells, and further wherein the particle heater structure is constructed such that it passes the Extractable Cytotoxicity Test.
METHODS FOR REDUCING PAIN DURING PHOTODYNAMIC THERAPY OF ACTINIC KERATOSIS
This present invention and its embodiments relates to methods for reducing pain during photodynamic therapy of actinic keratosis. The present invention also relates to methods of treating actinic keratosis with reduced pain during photodynamic therapy of actinic keratosis.
Method of Manufacture for Liquid Cannabinoids, and Modified CBD Oil Composition
A method of manufacturing a cannabinoid solution. The method first comprises providing a solution containing a volume of cannabidiol (CBD), as an oil. Preferably, the solution comprises at least 80% by volume of the CBD oil. The method also includes placing the volume of CBD oil into a container. The method further comprises determining a vibrational frequency of energy. The method then includes applying the determined vibrational frequency of energy to the solution within the container in order to imprint the volume of cannabinoid solution with the determined vibrational frequency. A cannabinoid solution comprising a volume of cannabidiol (CBD), as an oil, is also provided. The solution has been imprinted with one or more selected vibrational frequencies of energy.
LOCALIZED RELEASE OF SYSTEMICALLY CIRCULATING THERAPEUTIC SUBSTANCES
Presented herein are techniques for localized release of systemically circulating therapeutic substances, which combine many of the advantages of systematic and localized administration, while eliminating many of the associated drawbacks. More specifically, in accordance with the techniques presented herein, an electro-responsive biomaterial is systemically administered to a recipient of an electrically-stimulating implantable medical device. The electro-responsive biomaterial comprises a therapeutic substance that is only activated (e.g., released) in the presence of an electromagnetic field generated by the electrically-stimulating implantable medical device.
Ultrafine nanoparticles comprising a functionalized polyorganosiloxane matrix and including metal complexes; method for obtaining same and uses thereof in medical imaging and/or therapy
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. Thus, the nanoparticles according to the invention, with diameter d.sub.1 between 1 and 20 nm, each comprise a polyorganosiloxane (POS) matrix including gadolinium cations optionally associated with doping cations; a chelating graft C.sup.1 DTPABA (diethylenetriaminepentaacetic acid bisanhydride) bound to the POS matrix by an —Si—C— covalent bond, and present in sufficient quantity to be able to complex all the gadolinium cations; and optionally another functionalizing graft Gf* bound to the POS matrix by an —Si—C— covalent bond (where Gf* can be derived from a hydrophilic compound (PEG); from a compound having an active ingredient PA1; from a targeting compound; from a luminescent compound (fluorescein). The method for the production of these nanoparticles and the applications thereof in imaging and in therapy also form part of the invention.
Multifunctional nanoparticle compositions and uses thereof
Disclosed herein are multifunctional nanoparticle compositions. The compositions can be useful for the treatment of cancer by enhancing the anti-tumor effectiveness of radiation directed to a tissue, cell or a tumor and the methods of use thereof. The multifunctional nanoparticle composition comprises a metal oxide nanoparticle core; a functional coating on the surface of the metal oxide nanoparticle core; and a matrix carrier in which the coated nanoparticle is embedded.
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.
