The Mobility of Chondroitin Sulfate in Articular and Artificial Cartilage Characterized by C-13 Magic-Angle Spinning NMR Spectroscopy
Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)We have studied the molecular dynamics of one of the major macromolecules in articular cartilage, chondroitin sulfate. Applying C-13 high-resolution magic-angle spinning NMR techniques, the NMR signals of all rigid macromolecules in cartilage can be suppressed, allowing the exclusive detection of the highly mobile chondroitin sulfate. The technique is also used to detect the chondroitin sulfate in artificial tissue-engineered cartilage. The tissue-engineered material that is based on matrix producing chondrocytes cultured in a collagen gel should provide properties as close as possible to those of the natural cartilage. Nuclear relaxation times of the chondroitin sulfate were determined for both tissues. Although T-1 relaxation times are rather similar, the T-2 relaxation in tissue-engineered cartilage is significantly shorter. This suggests that the motions of chondroitin sulfate in data:rat and artificial cartilage different. The nuclear relaxation times of chondroitin sulfate in natural and tissue-engineered cartilage were modeled using a broad distribution function for the motional correlation times. Although the description of the microscopic molecular dynamics of the chondroitin sulfate in natural and artificial cartilage required the identical broad distribution functions for the correlation times of motion, significant differences in the correlation times of motion that are extracted from the model indicate that the artificial tissue does not fully meet the standards of the natural ideal. This could also be confirmed by macroscopic biomechanical elasticity measurements. Nevertheless, these results suggest that NMR is a useful tool for the investigation of the quality of artificially engineered tissue. (C) 2010 Wiley Periodicals, Inc.

The Order–Disorder Transition in Graft Block Copolymers
The order–disorder
transitions of diblock copolymers grafted
to a common backbone were examined by oscillatory shear rheology and
small-angle X-ray scattering. The effect of grafting density, graft
molecular weight, number of grafts, and backbone dispersity were studied
using poly[(styrene-<i>alt</i>-<i>N</i>-hydroxyethylmaleimide)-<i>random</i>-(styrene-<i>alt</i>-<i>N</i>-ethylmaleimide)]-<i>graft</i>-poly(4-methylcaprolactone-<i>block</i>-d,l-lactide) [PSHE-<i>g</i>-(P4MCL-PLA)]
as a model graft block copolymer. At high grafting densities (25–50%),
the order–disorder temperature (<i>T</i><sub>ODT</sub>) of the graft polymers was nearly identical to the analogous linear
diblock. At lower grafting densities (<25%), the <i>T</i><sub>ODT</sub> was found to systematically decrease. The number of
grafts did not significantly change the value of the <i>T</i><sub>ODT</sub>; however, increasing the number of grafts resulted
in broad, ill-defined transitions. Backbone dispersity was found to
have little impact on the <i>T</i><sub>ODT</sub>. Ordered
morphologies were imaged by transmission electron microscopy. Long-range
order was observed in polymers with at least 10 grafts/chain
