Axial flow catalyst pack

A stack of very thin metal plates provides high surface area for catalytic decomposition of a fluid flowing axially from upstream to downstream through the stack. Each plate has flow-through passages of selected size and location to promote uniform flow and good surface contact with a catalyst surface on the plates. The downstream surface of each plate is etched to provide gaps between plates for lateral fluid flow. The plates are divided into groups separated by metering plates that promote more uniform flow from group to group.

Novel peptide-based scaffolds for cartilage regeneration and methods for their use

Disclosed herein are novel peptide amphiphile molecules and compositions composed of a peptide sequence that non-covalently binds the growth factor TGF-β1. Also disclosed are methods of using these peptide amphiphiles to create a gel scaffold in situ that enhances articular cartilage regeneration when used in combination with microfracture. Significant improvement in tissue quality and overall O'Driscoll histological scores were observed in rabbits with full thickness articular cartilage defects treated with the TGF-binding peptide amphiphile. The gel can further serve as a delivery vehicle for recombinant TGF-β1 protein growth factor. Scaffolds that localize and retain chondrogenic growth factors may synergistically enhance cartilage repair when combined with microfracture, by inducing bone marrow mesenchymal stem cells into chondrogenic differentiation.
