Calcium phosphate (Ca-P) coatings on zirconia bone implants have a great potential to improve the osseointegration of already existing ceramic implants, owing to their bone-bonding ability and high osteoconductive characteristics. In our study, we have prepared three different kinds of Ca-P coatings, namely the octacalcium phosphate (OCP), hydroxyapatite (HAp) and β-tricalcium phosphate (β-TCP)...

Enamel matrix proteins, including the most abundant amelogenin and lesser amounts of enamelin, ameloblastin, and proteinases, play vital roles in controlling crystal nucleation and growth during enamel formation. The cooperative action between amelogenin and the 32-kDa enamelin is critical to regulating the growth morphology of octacalcium phosphate crystals. Using biophysical methods, we inves...

The osteoconductive and possibly osteoinductive characteristics of OCP increased the interest in preparation of bone graft materials that contain OCP in its composition. Calcium phosphate cements (CPCs) were prepared using a mixture of α-tricalcium phosphate (α-TCP) and dicalcium phosphate anhydrous (DCPA), with α-TCP / DCPA molar ratio of 1/1 and distilled water or 0.5 mol / L phosphate aqueou...

We report the creation of motif-based artificial proteins that bind to titanium surfaces and mediate the deposition of crystalline calcium phosphate. These proteins enabled in aqua surface modification of titanium materials having an intricate structure used in medical applications.

removal of thiosulfate (s2o32-, 200 mg/l) from simulated wastewater samples was investigated under varying co-pollutants and ph conditions employing the titanium dioxide (tio2) mediated photocatalysis. for thiosulfate only studies higher substrate removal was noted at lower ph with a specific trend of ph 4 > ph 7 > ph 10. furthermore, near complete thiosulfate removal was also achieved at ph 4....

Calcium pyrophosphate hydrate (CPP, Ca(2)P(2)O(7) · nH2O) and calcium orthophosphate compounds (including apatite, octacalcium phosphate etc.) are among the most prevalent pathological calcifications in joints. Even though only two dihydrated forms of CPP (CPPD) have been detected in vivo (monoclinic and triclinic CPPD), investigations of other hydrated forms such as tetrahydrated or amorphous ...

Lesions involving the osteochondral unit are difficult to treat. Biomimetic scaffolds previously shown as promising alternative. Such devices often lack multiple functional layers that mimic bone, cartilage, and interface. In this study, multilayered developed based on use of natural extracellular matrix (ECM)-like biopolymers. Particular attention is paid obtain a complex mimics native transit...
