摘要:
The present invention relates to methods and compositions for the production of scaffolds, such scaffolds to be used for a variety of purposes, including tissue engineering. More specifically, the present invention relates to the use of fused crystals, such as fused salt crystals to form a framework. The methods for producing the scaffolds of this invention improve the porosity, interconnectivity and ease of manufacture as compared to prior art methods.

Disclosed are advantageous methods for patterning and/or mineralizing biomaterial surfaces. The techniques described are particularly useful for generating three-dimensional or contoured bioimplant materials with patterned surfaces or patterned, mineralized surfaces. Also provided are various methods of using the mineralized and/or patterned biomaterials in tissue engineering, such as bone tissue engineering, providing more control over ongoing biological processes, such as mineralization, growth factor release, cellular attachment and tissue growth.

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.

Controlled release of biopharmaceutical growth factors from a hydroxyapatite coating on a bioresorbable interference screw used in cruciate ligament reconstruction surgery on a human. Biologically active scaffolds, such as interference bone screws used for ligament fixation, made by growing calcium phosphate-based hydroxyapatite coatings on bioresorbable poly(α-hydroxy ester) scaffolds that provide controlled mineral dissolution and controlled release of bone morphogenetic protein-2. The biologically active scaffold provides improved bioavailability of BMP-2 growth factor that in turn provides enhanced graft-bone healing in the tibial bone tunnel. The coating method uses surface hydrolysis and modified simulated body fluid incubation which does not require solvent or heat and is conducted at room temperature.
摘要:
A method for forming a reactive medium for removing homogenous and heterogeneous impurities from a fluid is provided which includes forming a uniform oxide layer on all exposed surfaces of a porous metal substrate, depositing at least one layer of carbon on substantially all of the oxide layer formed on the porous metal substrate, depositing a precursor metal species on the carbon layer, and heating the porous metal substrate containing the carbon layer to form active sites on the carbon layer, wherein the active sites include at least partially deoxygenated metal species chemically bonded to the carbon layer. Also provided is a reactive medium for purifying a fluid, the reactive medium comprising a porous inorganic substrate, a layer including carbon and an oxide layer between the porous inorganic substrate and the layer including carbon. The reactive medium further comprises active sites including at least partially deoxygenated metal species, the active sites being bonded to the layer including carbon.

摘要:
A dough composition for making quality, thinly sheeted farinaceous food products such as pie crust or the like and which is shelf stable. The dough composition contains a high-starch, low-enzyme flour, shortening, water, gluten and preservatives. The composition is particularly adapted for making a pie dough which, during manufacture, is pre-sheeted and folded twice for packaging, and then is unfolded by the consumer for use.
