Disclosed herein are methods of detecting tumors, monitoring cancer therapy, and selectively inhibiting the proliferation and/or killing of cancer cells utilizing a papilloma pseudovirus or a papilloma virus-like particle (VLP).

The present invention relates to an emulsion composition for chemoembolization comprising a nanoparticle comprising a drug and a biocompatible polymer, a water-soluble contrast agent and a water-insoluble contrast agent, and a water-insoluble drug as well as an aqueous drug can be administered in a form of stable emulsion, and drugs are slowly released, thereby enhancing the effect of chemoembolization.

The present invention describes an X-ray contrast composition for local administration, wherein the X-ray contrast composition exhibits contrast properties and wherein at least 60% of an administrated amount of said X-ray contrast composition remains more than 24 hours within 10 cm from an injection point when the X-ray contrast composition is administrated to a human or animal body.

This invention concerns imageable, radiopaque embolic beads, which are particularly useful for monitoring embolization procedures. The beads comprise iodine containing compounds which are covalently incorporated into the polymer network of a preformed hydrogel bead. The beads are prepared by activating pre-formed hydrogel beads towards nucleophilic attack and then covalently attaching iodinated compounds into the polymer network. The radiopaque beads may be loaded with chemotherapeutic agents and used in methods of embolizing hyperplastic tissue or solid tumors.

The present invention relates to compositions and methods for imaging and treating various diseases and disorders, including cancers. The composition of the invention can include a plurality of biodegradable micro-beads, each embedding a plurality of nano-beads, further including a polymer, a radionuclide, a radionuclide chelator, a radioligand, a chemotherapeutic agent, and a cell-penetrating peptide. Upon injection into a blood vessel supplying a cancer tumor, the micro-beads lodge into the tumor and degrade, releasing the nano-beads with a therapeutic or diagnostic agent. The compositions and methods of the invention provide a more homogeneous and deeper distribution of radiation or chemotherapeutic agents throughout the target tumor. The micro-beads provide a local, sustained, and controlled delivery nano-beads including therapeutic or diagnostic agents.
