摘要:
Described herein are pharmaceutical formulations for the treatment of hypercholesterolemia, comprising nanoparticles having a polymeric hydrophobic core which is associated with an inhibitor of PCSK9. The inhibitor may be EGF-A, EGF-B, or an siRNA. Preferred polymers include chitosan. The nanoparticle may further include a hydrophilic shell coating the core.

Provided is a peptide and a hydrogel prepared therefrom. The peptide comprises the sequence Gly-(A)-(Gly-X-Y) m -M-(Gly-X-Y) n -Gly-(B)-Gly, wherein A and B are telopeptides, X and Y are any amino acid, m and n are integers of at least 3 and M is a receptor binding sequence. Artificial collagen derived from the peptide of the invention provides an alternative to the use of animal- or human-derived collagen in industrial, biological and biomedical applications.
摘要:
Disclosed herein are bioresorbable stents which elute nitric oxide (NO). The stent is comprised of three main key design elements: a bioresorbable scaffold, a bioresorbable polymeric coating layer(s), and NO-releasing nanoparticles incorporated in the bioresorbable polymeric coating layer, and optionally also in the scaffold. The NO-releasing nanoparticles are made of nontoxic biocompatible and biodegradable materials; for example a chitosan polymer and optionally a sugar.
