摘要:
The present disclosure provides radiopaque crosslinked acrylamide copolymers that comprise (a) a monofunctional acrylamide monomer containing one or more radiopaque atoms and/or a multifunctional acrylamide monomer containing one or more radiopaque atoms and (b) a monofunctional acrylamide monomer that does not contain one or more radiopaque atoms and/or a multifunctional acrylamide monomer that does not contain one or more radiopaque atoms, wherein the copolymer comprises at least one multifunctional acrylamide monomer. The present disclosure also provides radiopaque particulate compositions that comprise such radiopaque crosslinked acrylamide copolymers and medical procedures that comprise administering to a subject such radiopaque particulate compositions. The present disclosure further provides methods of making such radiopaque crosslinked acrylamide copolymers.
摘要:
Spray-dried metal-organic frameworks (MOFs) comprising therapeutic and/or diagnostic metal ions and therapeutic and/or diagnostic organic ligands are described. Both the metal ion and organic ligand can have activity related to the treatment and/or diagnosis of a pulmonary disease or disorder, such as tuberculosis, or another disease related to a pulmonary infection. The MOFs can be adminstered to subjects via inhalation (e.g., as aerosols). Methods of treating and diagnosing pulmonary diseases or disorders are also described.
摘要:
The present invention is directed towards a system and method for transarterial chemoembolization using differently sized drug-eluting microsphere beads filled with drugs and determining a delivered drug concentration using an imaging system.
摘要:
This invention provides methods for the formation of biocompatible membranes around biological materials using photopolymerization of water soluble molecules. The membranes can be used as a covering to encapsulate biological materials or biomedical devices, as a “glue” to cause more than one biological substance to adhere together, or as carriers for biologically active species. Several methods for forming these membranes are provided. Each of these methods utilizes a polymerization system containing water-soluble macromers, species, which are at once polymers and macromolecules capable of further polymerization. The macromers are polymerized using a photoinitiator (such as a dye), optionally a cocatalyst, optionally an accelerator, and radiation in the form of visible or long wavelength UV light. The reaction occurs either by suspension polymerization or by interfacial polymerization. The polymer membrane can be formed directly on the surface of the biological material, or it can be formed on material, which is already encapsulated.

摘要:
The present invention relates to a composition suitable for administration to a subject, the composition comprising pharmacologically acceptable particulate material dispersed throughout a pharmacologically acceptable liquid carrier, the particulate material being maintained in the dispersed state by a steric stabilizer, wherein the steric stabilizer is a polymeric material comprising a steric stabilizing polymeric segment and an anchoring polymeric segment, one or both of which are derived from one or more ethylenically unsaturated monomers that have been polymerized by a living polymerization technique, wherein the steric stabilizing polymeric segment is different from the anchoring polymeric segment, and wherein the anchoring polymeric segment has an affinity toward the surface of the particulate material and secures the stabilizer to the particulate material.
摘要:
A microcapsule for the local treatment of a tumor is proposed. The microcapsule has a support material forming a casing for the microcapsule, an active agent that damages tumor cells, a marker material suitable for use as an x-ray marker, and at least one magnetic nanoparticle. The active agent in particular destroys the tumor cells.
摘要:
Low density microspheres, methods for preparing same, and use of same as contrast agents are described. The microspheres have a void which contains a gas or the vapor of a volatile liquid selected from the group consisting of aliphatic hydrocarbons, chlorofluorocarbons, tetraalkyl silanes and perfluorocarbons.
摘要:
Particles are provided for use in therapeutic and/or diagnostic procedures. The particles include poly[bis(trifluoroethoxy) phosphazene] and/or a derivatives thereof which may be present throughout the particles or within an outer coating of the particles. The particles can also include a core having a hydrogel formed from an acrylic-based polymer. Barium sulfate may also be provided to the core of the particles as a coating or absorbed within the core of the particles. The particles can be used to minimize blood flow to mammalian tissues by occluding at least a portion of a blood vessel of the mammal, or to deliver an active agent to a localized area within a body of a mammal by contacting a localized area with at least one of the particles. Further, the particles are useful in sustained release formulations including active agent(s) for oral administration, as tracer particles for injection into the bloodstream of a mammal or for use in enhanced ultrasound imaging. The particles may include agents for increasing density for achieving useful buoyancy levels in suspension.
