In the past decade, tissue engineering-based bone grafting has emerged as a viable alternative to biological and synthetic grafts. The biomaterial component is a critical determinant of the ultimate success of the tissue-engineered graft. Because no single existing material possesses all the necessary properties required in an ideal bone graft, our approach has been to develop a three dimension...

Phosphate-based glasses have been examined in many studies as a potential biomaterial for bone repair because of its degradation properties, which can be controlled and allow the release of various elements to promote osteogenic tissue growth. However most of these experiments studied either tertiary or quaternary glass systems. This study investigated a qinternary system that included titanium...

Respiration drives the accumulation of a small amount of calcium in corn (Zea mays L.) mitochondria, and this calcium is released when respiration ceases. A postenergized addition of phosphate leads to phosphate uptake and enhaced calcium retention. Oligomycin, KCN, 2,4-dinitrophenol, or mersalyl are without effect on the phosphate-induced calcium retention. Addition of phosphate also inhibits ...

The effect of zinc phosphate (ZP) and zinc calcium phosphate (ZCP) coatings on the reinforcing mechanisms of smooth steel fiber in cementitious matrix have been studied. The results of pull out tests illustrated that by coating smooth steel fiber the pull-out load may be increased up to 100%. The effect of zinc phosphate coating on interface bonding was more than zinc-calcium phosphate coating....

Understanding glass structure is still challenging due to the result of disorder, although novel materials design on the basis of atomistic structure has been strongly demanded. Here we report on the atomic structures of the zinc phosphate glass determined by reverse Monte Carlo modelling based on diffraction and spectroscopic data. The zinc-rich glass exhibits the network formed by ZnOx (avera...

Ideally, bioactive ceramics for use in alveolar ridge augmentation should possess the ability to activate bone formation and, thus, cause the differentiation of osteoprogenitor cells into osteoblasts at their surfaces. Therefore, in order to evaluate the osteogenic potential of novel bone substitute materials, it is important to examine their effect on osteoblastic differentiation. This study e...

Calcium phosphate nanoparticles are suitable as scaffolds for bone regeneration; however, few reports on available calcium phosphate-based biomaterials with an antibacterial property drug carriers. Lei Nie and colleagues developed silver-doped biphasic phosphate/alginate microclusters using the double-emulsions method. The cover image shows SEM micrograph of prepared in which spherical shape su...
