Fusarium polycaprolactone depolymerase is cutinase
Results together with other details of regulation and conditions for optimal enzyme activity indicate that the Fusarium PCL depolymerase, required for degradation and utilization of PCL, is cutinase.
Poly(3-hydroxybutyrate)-co-(3-hydroxyvalerate)/Poly-L-lactide blends: Thermal and mechanical properties
Blends of poly(3-hydroxybutyrate)–poly(3-hydroxyvalerate) (PHBV) and poly(L-lactides) (PLLA) have been prepared by solvent casting. Compatibility, thermal behavior, morphology, and mechanical
A biodegradable composite artificial tendon
The development of a completely biodegradable composite artificial tendon prosthesis that mimics the structure and stress-strain response of natural tendon is presented. The artificial tendon is a
Composite hydrogels for intervertebral disc prostheses
Different PHEMA/PCL semi-IPNs hydrogels and their relative composite systems reinforced with PET fibres have been investigated for potential use as intervertebral disc prostheses. Compression
Synthesis and characterization of a new interpenetrated poly(2-hydroxyethylmethacrylate)-gelatin composite polymer.
In vivo biocompatibility experiments and in vitro tests confirmed an improved ability of this composite to scaffold for the cells, and a progressive gelatin degradation from the surface to the bulk of the poly(HEMA)-gelatin specimens during short-term (7 d) implantation.
Physical characterization of incompatible blends of polymethylmethacrylate and polycaprolactone
Blends of polymethylmethacrylate (PMMA) and poly-e-caprolactone (PCL) were prepared and characterized. The analysis of the glass transition temperature indicates no compatibility of the two polymers,
Poly(2-hydroxyethyl methacrylate)/Poly(caprolactone) Semi-Interpenetrating Polymer Networks
Semi-interpenetrating polymer networks (semi-IPN's) composed of cross linked poly(2-hydroxyethyl methacrylate) (PHEMA), and linear poly(caprolac tone) (PCL), display improved mechanical properties
Poly(aspartic acid): Synthesis, biodegradation, and current applications
Poly(aspartic acid) is a biodegradable, water-soluble polymer that is valuable in numerous industrial applications. A variety of synthetic methods can be utilized to prepare poly(aspartic acid) and
Copolymers of itaconic anhydride and methacrylate-terminated poly(lactic acid) macromonomers.
In an effort to design cyclic anhydride copolymers that have biodegradable characteristics and are derived from renewable resources, the copolymerization of itaconic anhydride and
The differential effects of poly(2-hydroxyethyl methacrylate) and poly(2-hydroxyethyl methacrylate)/poly(caprolactone) polymers on cell proliferation and collagen synthesis by human lung fibroblasts.
The results suggest that control of cell growth and metabolism by biomedical polymers is based on physicochemical mechanism(s) in which the hydrophilicity/hydrophobicity ratio of the material surfaces may play an important role.
