Three dimensional printing was investigated for fabricating hydroxyapatite (HA) and tricalcium phosphate ( -TCP) composite scaffolds using calcium phosphate based ceramics and calcium phosphate cement chemistry. Scaffolds were formed by printing an aqueous sodium phosphate solution on the powder bed consisting of a mixture of dicalcium phosphate anhydrous (DCPA) and calcium hydroxide powders. T...

Burkholderia cepacia CC-Al74 with a high ability for solubilizing tricalcium phosphate (TCP) was used to study the P-solubilization mechanism. We collected filtrates able to solubilize TCP from the cultures of strain CC-Al74 and demonstrated that the P-solubilization increased from 0 microg ml(-1) to 200 microg ml(-1) during exponential growth, when the pH decreased from 8 to 3. HPLC-analysis r...

In the course of our research, aimed at improving sugar beets phosphorus nutrition, we isolated and characterized Streptomyces sp. strains, endemic from beet fields Beni-Mellal region, which are able to use natural rock phosphate (RP) tricalcium (TCP) as sole sources. Ten isolates yielded a comparable biomass in presence these two insoluble sources, indicating that they were extract similar amo...

In recent years, ceramics, polymers, and composites have been used to develop biologically mechanically suitable bone scaffolds. β-tricalcium phosphate（β-TCP) is a widely bioceramic in tissue engineering. It shows excellent osteoconductivity, osteoinductivity, good biocompatibility properties, as its chemical composition similar the original structure of bone. Herein, we designed β-TCP-PLA comp...

introduction : osteon® is an alloplastic material containing 70% hydroxyapatite and 30% β-tcp. calcitonin, a hormone produced by the thyroid gland, not only prevents bone resorption by reducing both the number and the activity of osteoclasts, but also stimulates bone formation. considering the favorable effects of calcitonin on bone formation, we hypothesized that the addition of calcitonin to ...

Strontium (Sr) is known to positively affect the mechanism of bone remodelling. Consequently, calcium phosphate bioceramics associated with alginate matrices containing strontium could improve bone regeneration due to gradual strontium release. This work aims to incorporate Sr on microspheres of alginate (ALG)/β-tricalcium phosphate (β-TCP) and evaluates the in vitro release of strontium ions i...

A macroporous phosphate invert glass-ceramic (PIGC) was derived from the mother glass with a composition of 60CaO-30P2O5-3TiO27Na2O in mol%. The mother glass powders were coated on a polymer sponge skeleton and subsequently sintered at 850 C for 1 h through burning off the sponge, resulting in the preparation of macroporous PIGC. The resulting macroporous PIGC consists predominantly of tricalci...

The purpose of this study was to compare bone regeneration and space maintaining ability of three-dimensional (3D) printed bone grafts with conventional biphasic calcium phosphate (BCP). After mixing polycaprolactone (PCL), poly (lactic-co-glycolic acid) (PLGA), and β-tricalcium phosphate (β-TCP) in a 4:4:2 ratio, PCL/PLGA/β-TCP particulate bone grafts were fabricated using 3D printing technolo...

Calcium phosphate cements (CPCs) use the simultaneous presence of several calcium phosphates phases. This is done to generate specific bulk and in vivo properties. This work has processed and evaluated novel multiphasic CPCs containing dual tricalcium phosphate (TCPs) phases. Dual TCPs containing α- and β-TCP phases were obtained by thermal treatment. Standard CPC (S-CPC) was composed of α-TCP,...

Objective: In the present paper, it was purposed to examine late impacts of bone tissue recoveries in combination with synthetic grafts and Ankaferd Blood Stopper (ABS), which are effective wound healing diabetic rats.
 Methods: A total 64 Wistar albino male rats diabetes were studied. deformity generated calvarium rats. These divided into 4 different groups. Only saline applied defect gro...
