Readily available hydrophilic and small organofluorine moieties were condensed via “click chemistry” to generate nonionic hydrophilic fluorinated molecules with unique .sup.19F MR signatures. These were used to fabricate stable liposome formulations for imaging various tissue types. This approach was tailored to exploit the broad spectrum of organic .sup.19F molecular species and to generate probes with distinct .sup.19F MRI signatures for simultaneous assessment of multiple molecular targets within the same target volume.

A method for forming encapsulated gold nanoparticles mixes mangiferin into a liquid medium to form a reducing agent solution. Gold salts are mixed into the reducing agent solution. Reaction of the gold salts is permitted, in the absence of any other reducing agent, to form a nanoparticle solution of stabilized, biocompatible gold nanoparticles coated with mangiferin. The gold salts can consist of AuCl4, or can consist of radioactive gold salts. A cancer therapy method injects a solution of mangiferin encapsulated gold nanoparticles directly into a solid tumor. A solution consisting of an aqueous or alcoholic medium and mangiferin encapsulated gold nanoparticles is provided. The mangiferin encapsulated gold nanoparticles can have core sizes of ˜5-20 nm and total sizes of ˜20-120 nm.

A composition comprising including a homogeneous tin-117m colloid comprising tin-117m, and an ascorbic acid is provided, the composition naturally has a white coloration. The composition is visually distinct from a conventional homogeneous tin-117m colloid because conventional colloids have an orange-yellow color. The addition of ascorbic acid changes the color of the composition without adding toxicity and without changing the therapeutic effects of the homogeneous tin-117m colloid. A use and a method of making the same is also provided.

The invention provides a scanning suspension comprising a particle which is capable of at least in part disturbing a magnetic field, wherein said particle comprises a diameter of at least 1 μm, and use thereof for obtaining a scanning image. Preferably, said particle comprises holmium and a composition capable of essentially maintaining its structure during irradiation. A particle of the invention is suitable for preparing a kit of parts, comprising a diagnostic and a therapeutic composition which both comprise particles of the invention with essentially the same chemical structure, wherein said therapeutic composition is more radioactive than said diagnostic composition. Said kit of parts is especially suitable for treatment of a tumor. First, the distribution of a particle of the invention within an individual can be determined with a scanning image obtained with said scanning composition. Subsequently, a radioactive therapeutic composition can be administered, wherein a suitable dose of said therapeutic composition is derived from said scanning image.

A tissue sealant for use in surgical and medical procedures for sealing the tissues of a living mammal is provided. The tissue sealant comprises a hydrogel which is formed by gelation of a premix disposed on the tissue to be sealed. The premix comprises alkylated chitosan or a gelatin, and a polybasic carboxylic acid or an oxidized polysaccharide, in an aqueous medium. The premix can also include a dehydrating reagent, a carboxyl activating reagent, or both. A specific use of the tissue sealant is in the repair of the dura mater after brain surgery to prevent leakage of cerebrospinal fluid. The tissue sealant may include a therapeutic or protective agent such as an antibiotic or an anti-inflammatory drug.

This invention relates to a ceramic module for assembly into a therapeutic device for treating a human or animal body with irradiation of far infrared radiation and low dose ionizing radiation based on radiation hormesis effect. More specifically, the invention relates to a ceramic module that simultaneously emits far infrared radiation within 3-16 μm wavelength spectrum and ionizing radiation at a specific dose rate in the range of 0.1-11 μSv/h (micro-Sieverts per hour). Said ceramic module may be used alone or serve as components of a therapeutic device for increasing physiologic performance, immune competence, health, and mean lifespan of human or animal.

A nanoparticle is provided. The nanoparticle includes a magnetic core including a magnetic nanocrystal, a fluorophore coupled to the magnetic core, at least one chelating compound coupled to the magnetic core, the at least one chelating compound being a compound that chelates copper-64 (.sup.64Cu), a compound that chelates technetium-99m (.sup.99mTc), or a combination thereof, and an iodine chelator coupled to the magnetic core. Methods of making the nanoparticle and of using the nanoparticle as a multi-modal contrast agent are also provided.

A method and system that is directed to the local delivery of growth factors to the mammalian CNS to treat CNS disorders associated with neuronal death and/or dysfunction is described.

A plurality of artificial red blood cell particles includes each particle of the plurality being substantially monodisperse and each particle having a largest common linear dimension of about 5 μm to about 10 μm. The particles can also have a modulus configured such that a particle of the plurality of particles can pass through a tube having an inner diameter of less than about 3 μm.

A composition of microparticles includes a non-radioactive and a radioactive isotope, and an injection vehicle, for use in the intratumoral treatment of cancer, by combined antitumoral effect of radioactivity and intratumoral microparticle deposition. The antitumoral effect provided by the cytotoxicity of radioactivity is enhanced by a modulation of the tumoral immune response induced by microparticle deposition inside the tumor, thereby decreasing the dose of radioactivity required to treat solid tumors. A method of treating solid tumors using a sub-optimal tumor-volume coverage dose of radioactivity combined with intratumoral microparticle deposition as a mean of tumor control is also disclosed.
