Cell-mediated protein release from calcium-phosphate-coated titanium implants.
Implants used in dental and orthopaedic surgery should become osseointegrated into native bone. In an endeavour to potentiate bone formation, prostheses, coated with a coprecipitated layer of calcium phosphate and the osteogenic agent BMP-2, were implanted at an ectopic site in rats. Five weeks later, the implants were surrounded by a substantial mass of bone. Our findings indicate that the dru...

15 صفحه اولThe Effect of HLB on the Release Profile of Atenolol from Ethyl Cellulose-coated Tablets
It is possible to alter the permeability of ethyl cellulose membrane with certain materials such as surfactants. In this study the effect of surfactant concentration and different HLB values on the release rate of atenolol from ethyl cellulose-coated tablets was evaluated. The results showed that when the concentration of surfactant increased, the rate of drug release also increased. The kineti...
متن کاملA Rapid Technique for Prediction of Nutrient Release from Polymer Coated Controlled Release Fertilizers
Controlled release fertilizers (CRF) are produced with different rates and durations of nutrient release to cater to different crops with wide ranges of nutrient requirements. A rapid technique is needed to verify the label specifications of nutrient release rate and duration. Polymer-coated urea (PCU) (43% nitrogen [N]) and polymer-coated N, phosphorus (P), potassium (K) (PC_NPK; 14-14-14) fer...
