Smad2-dependent glycosaminoglycan elongation in aortic valve interstitial cells enhances binding of LDL to proteoglycans [PDF]

, 2013
Calcific aortic valve disease is a progressive condition that shares some common pathogenic features with atherosclerosis. Transforming growth factor-ß1 is a recognized mediator of atherosclerosis and is expressed in aortic valve lesions.

One‐Step Covalent Biofunctionalization of Tubular Constructs Enabled by Surface‐Embedded Radicals

Advanced Materials Technologies, EarlyView.
Uniform covalent biofunctionalization of tubular constructs is achieved in one step using surface‐embedded radicals generated by a novel plasma immersion ion implantation (PIII) technology. This scalable, solvent‐free technology advances bioengineered tubes for tissue engineering and implant applications.
