Abstract: The present invention relates in general to compositions and methods for treating an animal or human patient in need of treatment for ophthalmic diseases or conditions involving oxidative stress and treatment with an ophthalmic implant containing (2R,2R?)-3,3?-disulfanediyl bis(2-cetamidopropanamide) (diNACA), wherein such ophthalmic diseases or conditions include but not limited to cataracts, cataracts in a subject that does not have diabetes, corneal endothelial cell loss, age-related macular degeneration, presbyopia, retinitis pigmentosa (RP), Usher syndrome, Stargardt syndrome, glaucoma, diabetic retinopathy, and/or retinal disease.

Abstract: A method of preparing a silicon-containing polymeric structure coated/encapsulated active ingredient is disclosed. The method has the steps of providing an insoluble active ingredient; dispersing the active ingredient in a liquid medium to form a suspension of the active ingredient; adding a silicon-containing polymeric structure precursor to the suspension; and reacting the precursor to form the silicon-containing polymeric structure. The silicon-containing polymeric structure is formed around the active ingredient, thereby forming a silicon-containing polymeric structure coated/encapsulated active ingredient. The silicon-containing polymeric structure coated/encapsulated active ingredient may be used in place of the active ingredient itself.

Abstract: Compositions, methods of making, and methods of using nanoclusters in which the nanoclusters comprise a plurality of nanoparticles having a core of nanoparticles arranged such that the surfaces of the nanoparticles contact adjacent nanoparticles, the nanoparticles comprise an active ingredient, and the nanocluster has a mass median aerodynamic diameter of from about 0.25 ?m to about 20 ?m.

Abstract: Acid-labile poly(N-vinyl formamide) (“PNVF”) nanocapsules were synthesized by free radical polymerization of N-vinyl formamide with optional active ingredients on the surface of silica nanoparticles. Polymerization in the presence of a novel cross-linker that contains an acid-labile ketal facilitated stable etching of silica nanoparticle templates using sodium hydroxide and recovery of PNVF nanocapsules. The formamido side group of PNVF was then hydrolyzed by extended exposure to sodium hydroxide to produce polyvinylamine (“PVAm”) nanocapsules. PNVF and PVAm nanoparticles are also synthesized that form nanogels with optional active ingredients.

Abstract: The present invention is directed to cationic lipid for the delivery of oligonucleotides and methods of modulating an expression of a targeted gene using the nanoparticle compositions. In particular, the invention relates to cholesterol and its derivatives having multiple positively charged moieties via branching spacers, and nanoparticle compositions of oligonucleotides encapsulated in a mixture of a cationic lipid, a fusogenic lipid and a PEG lipid.
