Abstract:
An ophthalmic formulation that includes nanoparticles. Each nanoparticle includes a shell which encapsulates sulfated non-anticoagulant heparin (SNACH), with or without hydrophobic anti-angiogenesis Tyrosine Kinase inhibitors. The SNACH is ionically or covalently bonded to the shell. The shell includes a polymer selected from the group consisting of poly (lactic-co-glycolic acid) (PLGA), chitosan, chitosan-alginate, and NIPAAM-APMAH-AA, wherein NIPAAM is N-isopropyl acrylamide, APMAH is N-3-aminopropylmethacrylamide hydrochloride, and AA is acrylic acid. A method for treating an eye disease of a subject includes: administering to an eye of the subject a therapeutically effective amount of the ophthalmic formulation for treating the eye disease. The eye disease involves an ocular angiogenesis-mediated disorder.

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:
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.
