The one-year survival of regenerated cartilage on a large articular surface is presented using the McDowell in vivo model. The model provides a mechanically shielded environment in which regenerated cartilage can be protected from intra-articular stresses while normal joint motion is maintained. New tissue was allowed to grow from bleeding subchondral bone for 12 weeks at which time the origina...
The conformational analysis of the synthetic peptide (formula, see text) has been carried out, as a model for small disulfide loops, in biologically active polypeptides. 1H NMR studies (270 MHz) establish that the Val(3) and Cys(4) NH groups are solvent shielded, while 13C studies establish an all-trans peptide backbone. Circular dichroism and Raman spectroscopy provide evidence for a right-han...
Modern means of communication rely on electric fields and currents to carry the flow of information. In contrast, biological systems follow a different paradigm that uses ion gradients and currents, flows of small molecules, and membrane electric potentials. Living organisms use a sophisticated arsenal of membrane receptors, channels, and pumps to control signal transduction to a degree that is...
The canonical CuAAC–ligand TBTA was capped with a bowl-shaped unit yielding the cage Hm-TBTA. shielded structure does not suffer from product inhibition effect and is remarkably tolerant to biological CuAAC-inhibitor Glutathione.
