Magnetic resonance velocity and temperature a shape memory polymer foam device
2010/2/25
Interventional medical devices based on thermally responsive shape memory polymer (SMP) are under development to treat stroke victims. The goals of these catheter-delivered devices include re-establis...
In Vitro Analysis of Biodegradable Polymer Blend/Hydroxyapatite Composites for Bone Tissue Engineering
biodegradable hydroxyapatite poly(caprolactone) PLGA tissue engineering
2009/12/22
Blends of biodegradable polymers, poly(caprolactone)
and poly(D,L-lactic-co-glycolic acid), have been examined
as scaffolds for applications in bone tissue engineering.
Hydroxyapatite granules have...
Characterization of osteoblast-like behavior of cultured bone marrow stromal cells on various polymer surfaces
biomaterials bone substitutes bone marrow osteoblast mineralization polymeric biomaterials
2009/12/22
The creation of novel bone substitutes requires a
detailed understanding of the interaction between cells and
materials. This study was designed to test certain polymers,
specifically poly(caprolac...
Enzymatic digestion of articular cartilage results in viscoelasticity changes that are consistent with polymer dynamics mechanisms
Enzymatic digestion articular cartilage results polymer dynamics mechanisms
