摘要:
Products, compositions, systems, and methods for modifying a target structure which mediates or is associated with a biological activity, including treatment of conditions, disorders, or diseases mediated by or associated with a target structure, such as a virus, cell, subcellular structure or extracellular structure. The methods may be performed in situ in a non-invasive manner by placing a nanoparticle having a metallic shell on at least a fraction of a surface in a vicinity of a target structure in a subject and applying an initiation energy to a subject thus producing an effect on or change to the target structure directly or via a modulation agent. The nanoparticle is configured, upon exposure to a first wavelength λ1, to generate a second wavelength λ2 of radiation having a higher energy than the first wavelength λ1. The methods may further be performed by application of an initiation energy to a subject in situ to activate a pharmaceutical agent directly or via an energy modulation agent, optionally in the presence of one or more plasmonics active agents, thus producing an effect on or change to the target structure. Kits containing products or compositions formulated or configured and systems for use in practicing these methods.
摘要:
A method and system for treating a subject with a disorder which provides within the subject at least one photoactivatable drug for treatment of the subject, applies initiation energy from at least one source to generate inside the subject a preferential x-ray flux for generation of Cherenkov radiation (CR) light capable of activating at least one photoactivatable drug, and from the CR light, activating inside the subject the at least one photoactivatable drug to thereby treat the disorder.

摘要:
A system and method for imaging or treating a disease in a human or animal body. The system provides to the human or animal body a pharmaceutical carrier including one or more phosphors which are capable of emitting ultraviolet or visible light into the body and which provide x-ray contrast. The system includes one or more devices which infuse a diseased site with a photoactivatable drug and the pharmaceutical carrier, an initiation energy source comprising an x-ray or high energy source which irradiates the diseased site with at least one of x-rays, gamma rays, or electrons to thereby initiate emission of said ultraviolet or visible light into the body, and a processor programmed to at least one of 1) produce images of the diseased site or 2) control a dose of said x-rays, gamma rays, or electrons to the diseased site for production of said ultraviolet or visible light at the diseased site to activate the photoactivatable drug.
摘要:
A system (and associated method) for treating a human or animal body. The system has a photoactivatable drug for treating a first diseased site, a first pharmaceutically acceptable carrier including one or more phosphorescent or fluorescent agents which are capable of emitting an activation energy into the body which activates the photoactivatable drug, a first device which infuses the first diseased site with a photoactivatable drug and the first pharmaceutically acceptable carrier, a first energy source which irradiates the diseased site with an initiation energy to thereby initiate emission of the activation energy into the body, and a supplemental treatment device which administers one or both of a therapeutic drug or radiation to the body at a second diseased site or the first diseased site, to provide an immune system stimulation in the body.
摘要:
A polymerizable composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and a phosphor capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.

摘要:
A method for treating a disease in a subject in need thereof is provided involving infusing 8-methoxypsoralen (8-MOP) and a phosphor-containing drug activator into a diseased site in the subject; and delivering a dose of x-rays to the subject for production of the ultraviolet and visible light inside the subject to activate the photoactivatable drug and induce a persistent therapeutic response, the dose including a pulsed sequence of x-rays delivering from 0.5-2 Gy to the tumor, wherein the phosphor-containing drug activator includes an admixture of two or more phosphors capable of emitting ultraviolet and visible light upon interaction with x-rays; the two or more phosphors including Zn2SiO4:Mn2+ and (3Ca3(PO4)2Ca(F, Cl)2: Sb3+, Mn2+) at a ratio (Zn2SiO4:Mn2+):(3Ca3(PO4)2Ca(F, Cl)2: Sb3+, Mn2+)) of from 1:10 to 10:1; wherein each of the two or more phosphors have at least one coating selected from an ethyl cellulose coating or a diamond-like carbon coating.
