Artificial cartilage materials for repair and replacement of cartilage (e.g., load-bearing, articular cartilage). The artificial cartilage materials described herein include triple-network hydrogels including a cross-linked fiber network (e.g., a bacterial cellulose nanofiber network) and a double-network hydrogel (e.g., a double-network hydrogel including polfacrylamide-methyl propyl sulfonic acid). The artificial cartilage may be coated onto or formed into an implant (e.g., plug). The artificial cartilage may include a surface macroporosity, e.g., 0.1-300 micrometers diameter. Also described herein are methods of forming and methods of using the triple-network hydrogel artificial cartilage materials.

The present invention is directed to a hemostatic material comprising a compacted, hemostatic aggregates of cellulosic fibers. In some aspects, the hemostatic material further includes additives, such as carboxymethyl cellulose (CMC) or other polysaccharides, calcium salts, anti-infective agents, hemostasis promoting agents, gelatin, collagen, or combinations thereof. In another aspect, the present invention is directed to a method of making the hemostatic materials described above by compacting a cellulosic-based material into hemostatic aggregates. In another aspect, the present invention is directed to a method of treating a wound by applying hemostatic materials described above onto and/or into the wound of a patient.

Resin compositions, layers, and interlayers comprising two or more thermoplastic polymers and at least one RI balancing agent for adjusting the refractive index of at least one of the resins or layers is provided. Such compositions, layers, and interlayers exhibit enhanced optical properties while retaining other properties, such as impact resistance and acoustic performance.

The present invention relates to a composition containing injectable mesenchymal stem cell-hydrogel and a method of preparing the same. Specifically, in a mesenchymal stem cell-hydrogel composition for injection prepared by a method of the present invention, since stem cells are attached to scaffolds in hydrogel beads, the stem cells are not easily lost or killed after the injection, and thus there is an advantage that an engraftment rate increases since the paracrine effect of the stem cells is continuously exhibited, and the stem cells are gradually released as hydrogel is degraded. In addition, the present invention has an advantage that healthy cells can be used without damages in cell membranes since injection formulation can be prepared without a treatment with proteolytic enzymes, and also a cryopreservation solution is easily removed from the mesenchymal stem cell-hydrogel beads even after freezing and thawing.
