Abstract:
A nano-composition that includes nanoparticles, a method of forming the nano-composition, and a method of using the composition. The nanoparticles include a polycationic polymer ionically bonded to one or more polyanionic Glycosaminoglycans (GAGs), wherein the polycationic polymer is chitosan, methylated chitosan, poly L-Lysine, or poly L-Arginine.
Abstract:
A method for treating a subject, such as a human patient, having a vascular disorder. The treatment method administers a therapeutic effective amount of a nanoparticle or a chemical structure to the subject to treat the disorders. The nanoparticle includes a poly L-arginine polymer and a Factor VIIa inhibitor conjugated to, or encapsulated in, the poly L-arginine polymer. The chemical structure includes a Factor VIIa inhibitor that includes at least one nitric oxide (NO) donor. The disorder may be sickle cell disease; stimulated or pathological angiogenesis associated disorders, cancer, ocular angiogenesis-mediated disorders such as diabetic retinopathy and macular degeneration, coagulation and/or platelet activation-associated disorders, pulmonary hypertension, or combinations thereof.
Abstract:
Disclosed are methods of treating subjects having conditions related to angiogenesis including administering an effective amount of a polymeric form of thyroid hormone, or an antagonist thereof, to promote or inhibit angiogenesis in the subject. Compositions of the polymeric forms of thyroid hormone, or thyroid hormone analogs, are also disclosed.

Abstract:
A silver nanocomposite, a formation method for forming the silver nanocomposite, and an application method utilizing the silver nanocomposite. The silver nanocomposite includes a silver nanoparticle conjugated to a glycosaminoglycan (GAG) or glucose. The formation method includes chemically reacting silver nitrate with a reducing agent to form a silver nanoparticle conjugated to the reducing agent of a GAG or glucose. The application method may include topically applying the silver nanocomposite to a wound or burn as an anti-microbial with respect to an antibiotic-resistant genotype in the wound or burn, wherein the silver nanocomposite topically applied includes the silver nanoparticle conjugated to the GAG of 2,6-diaminopyridinyl heparin (DAPHP) or hyaluronan (HA). The application method may include applying the silver nanocomposite as a coating to plastic, a catheter, or a surgical tool, wherein the silver nanocomposite applied as the coating includes the silver nanoparticle conjugated to the GAG of DAPHP.

Abstract:
The present invention is directed to compounds, compositions, and methods for halting or reversing the effects of chemoresistance in neoplastic diseases. In particular the use of hydroxylamines is described.
Abstract:
Antibodies directed against an antigenic determinant of high molecular weight kininogen domain 5, particularly a determinant located in the region formed by light chain amino acids Gly(440) to Lys(502), inhibit angiogenesis.
Abstract:
Peptide analogs of the high molecular weight kininogen domain 5 are potent inhibitors of angiogenesis. The peptides have the formula X1-(HGLGHGHEQQHGKGH)-X2 (I) wherein X1 is from zero to 25 amino acids; X2 is from zero to 60 amino acids. Methods of inhibiting endothelial cell proliferation and angiogenesis are provided.
