Abstract: The present invention is a method and device for treating solid tumors utilizing shear thinning biomaterials compositions containing beta- or alpha emitting radiation sources, polymer matrix, and/or radiopaque agent. The novel radioactive composition which is disclosed here, can be injected percutaneously or via transcatheter vascular route into the target environment for the locoregional treatment. This invention is comprised of a shear thinning biomaterial which, when combined with a radioactive isotope source, can provide a therapeutic dose of radiation locally to the tumor site minimizing the risk of damage to surrounding tissue. The device may be used either as the primary tumor treatment or for treatment of residual cancer cells after excision of the primary tumor. The present invention provides a method for making the shear thinning radioactive biomaterial composition, as well as a method for utilizing the composition as a part of the treatment method.

Abstract: Methods and compositions are described for use in encouraging angiogenesis and skin healing as may be utilized in wound treatment as well as in encouragement of angiogenesis in disease. Compositions include an effective amount of at least one of a flavonoid and a chlorogenic acid that are natural extracts of Parrotia persica, or their derivatives, analogues, or homologs. Compounds based upon these natural extracts have been found to be highly effective in vascular formation and skin closure while exhibiting low toxicity.

Abstract: A deacetylnemorone abietane diterpenoid is utilized in the prevention of growth and development of pathogenic cells, e.g., cancer cells. The deacetylnemorone can have the following structure: or a tautomer there of in which R1, R2, and R3 are independently selected from —H, C1-10 alkyl, C1-10 alkoxy, C1-10 alkenyl, C1-10 alkenoxy, —OH, —OAc, —CHO, -Ph, —OC6H5, —OC6H4OH, —COC6H5, —OCONH2, —OCONHCH3, —OCOC6H4NH2, —NH2, or ?O. The deacetylnemorone shows efficacy in treatment and prevention of a wide range of cancer types, as well as other neoplastic diseases as a chemo-preventative, a primary or secondary cytotoxic agent, a sensitizer for other therapies, or one component of a combinatorial treatment.
