摘要:
The present disclosure generally relates to biodegradable and bioresorbable materials having a mineral layer on the surface of the material. More particularly, the disclosure relates to biodegradable and bioresorbable orthopedic devices having a degradable mineral layer on the surface thereof that can be used as a delivery vehicle for biological substances. Also provided are various methods of using the mineralized devices in tissue regeneration, including bone tissue engineering, and methods for producing the mineralized devices.
摘要:
A modular peptide design strategy wherein the modular peptide has two functional units separated by a spacer portion is disclosed. More particularly, the design strategy combines a hydroxyapatite-binding portion and a biomolecule-derived portion. The modular peptides have improved non-covalent binding to the surface of the HA-based materials, and are capable of initiating osteogenesis, angiogenesis, and/or osteogenic differentiation.
摘要:
A system for growing tissue based upon layers of an inorganic extracellular matrix, wherein each layer of the inorganic matrix is designed to dissolve at a separate rate and result in sequential growth factor delivery upon its dissolution.

Biomaterials presenting synthetic peptides and methods of preparing biomaterials are disclosed. More particularly, the disclosure is directed to biomaterials including a substrate including a synthetic peptide thereon, wherein the synthetic peptide is selected from synthetic proteoglycan-binding peptides, synthetic glycosaminoglycan-binding peptides, and combinations thereof. The present disclosure is further directed to methods of preparing the biomaterials for use in sequestering endogenous proteoglycans and endogenous glycosaminoglycans, increasing stem cell proliferation, reducing spontaneous stem cell differentiation, and enhancing induced osteogenic differentiation of mesenchymal stem cells.

The present invention relates to a system and method for compensating for anode gain non-uniformity in a Multi-anode Position Sensitive Photomultiplier Tube (PS-PMT), in which a compensation unit is disposed between the multi-anode position sensitive photomultiplier tube and a position detection circuit unit and configured to uniform a current signal inputted to the position detection circuit unit, thereby compensating for anode gain non-uniformity. In accordance with the present invention, the compensation unit for changing resistance is used. Accordingly, there is an advantage in that the gain non-uniformity of each of the anodes of the PS-PMT can be compensated for. Furthermore, the gain non-uniformity of each of the anodes of the PS-PMT is compensated for by changing resistance values of the variable resistances of the compensation unit. Accordingly, there is an advantage in that the interaction positions of gamma rays can be calculated more precisely.
