Abstract:
This invention relates to photodynamic therapy (PDT) of vulnerable plaque using two pluralities of nanoparticles, one plurality comprising a PDT agent that is sensitive to blue-green light wherein the nanoparticles are capable of penetrating only into the fibrous cap of the vulnerable plaque and one plurality comprising a PDT agent that is sensitive to red light wherein the nanoparticles are capable of penetrating into the core of the vulnerable plaque.
Abstract:
The current invention relates to poly(amide) and poly(ester-amide) polymers, coatings including the polymers, and narrow polydispersity drug delivery particles including the polymers.
Abstract:
A method including advancing a delivery device through a lumen of a blood vessel to a particular region in the blood vessel; and introducing a composition including a sustained-release carrier and an apolipoprotein A-I (Apo A-I) synthetic mimetic peptide into a wall of the blood vessel at the particular region, wherein the peptide has a property that renders the peptide effective in reverse cholesterol transport. A composition including an apolipoprotein A-I (Apo A-I) synthetic peptide, or combination of an Apo A-I synthetic mimetic peptide and an Acyl CoA cholesterol: acyltransferase (ACAT) inhibitor in a form suitable for delivery into a blood vessel, the peptide including an amino acid sequence in an order reverse to an order of various Apo A-I mimetic peptides, or endogenous Apo A-I analogs, or a chimera of helix 1 and helix 9 of endogenous Apo A-I.
Abstract:
Disclosed are compositions with sustained-release carriers associated with at least two different types of growth factors and methods of fabrication and treatments thereof. In some embodiments, simultaneous release of the growth factors may be preferred while in other embodiments, sequential release of the growth factors may be preferred. Application of at least two growth factors to an injury site, e.g., compromised cardiac tissue caused by, for example, myocardial infarction or ischemic heart failure, may better mimic and induce the complex growth factor signaling pathways necessary to improve cardiac function. When applied to a patient after a myocardial infarction or ischemic heart failure, multiple growth factors within a sustained-release carrier platform or platforms may cause a synergistic effect on injected cells intending to alleviate left ventricle remodeling. Methods of treatment include percutaneous, sub-xiphoid, and open chest methods using catheters and/or syringes.
Abstract:
Described here are various compositions for the delivery active agents, e.g., antifungal agents. The compositions may be beneficial due to the particular release kinetics associated with them. Various locations and methods for placement of the compositions into the tissues of the nail unit, as well as tissues surrounding the nail unit are also described.

Abstract:
A method of modifying a medical device such as a stent with nano-constructs is disclosed. The method comprises applying a first fluid to the stent; immersing the stent being wet from the first fluid into a second fluid having a suspension of nano-constructs; and removing the stent from the second fluid and allowing the first and second fluid to be removed such that the nano-constructs are carried by the stent for in vivo application of the constructs to a target location of a mammalian subject. The nano-constructs can be attached to the surface of the stent, can be attached to a surface of the coating of the stent, can be embedded into the stent, or can be embedded into the coating.
