ꞵ-tricalcium phosphate (ꞵ-TCP) and anorthite are the main crystalline components in bone china bodies. The difference in their thermal expansion coefficients causes a decrease in the thermal shock resistance of the body. In this study, anorthite was replaced with bone ash at the bone china body, and the effect of this new composition on different properties of bone china, after curing at 1260 °...

Three types of ceramic scaffolds with different composition and structure [namely synthetic 100% hydroxyapatite (HA; Engipore), synthetic calcium phosphate multiphase biomaterial containing 67% silicon stabilized tricalcium phosphate (Si-TCP; Skelite) and natural bone mineral derived scaffolds (Bio-oss)] were seeded with mesenchymal stem cells (MSC) and ectopically implanted for 8 and 16 weeks ...

TCP is the most common and important transport layer protocol and its performance in the wireless environments is characterized by two path characteristics not normally present in wired environments: packet losses due to corruption and mobility.. In this research, we have used the perfect cellular model to model the wireless packet losses due to mobility and handoff in order to get the real per...

To assess potential effects of hyperbaric oxygen (HBOT) on artificial bone grafts, β - Tricalcium phosphate (β-TCP) and calcium phosphate coated bovine bone (CPCBB) substitutes were applied to standard bone defects in rat tibiae. The control defects were left empty. Half of the animals received 60 minutes of 2.4 atmosphere absolute (ATA) of HBOT. Rats were sacrificed at one, two and four weeks....

Hydroxyapatite/β-tricalcium phosphate (HA/β-TCP) composite scaffolds have shown great potential for bone-tissue engineering applications. In this work, ceramic scaffold with different HA/β-TCP compositions (pure HA, 60HA/40β-TCP, and 20HA/80β-TCP) were fabricated by a robotic-assisted deposition (robocasting) technique using water-based hydrogel inks. A systematic study was conducted to investi...

Recently, premixed calcium phosphate cement pastes have been proposed as biomaterials for bone tissue repair and regeneration. Use of saves the time removes an extra step during a medical operation. α-Tricalcium (α-TCP) based cements set to form deficient hydroxyapatite which has moderate bioresorbtion speed. α-TCP require setting aid, usually sodium or potassium salt, speed up process. Within ...

Bone diseases such as osteoporosis, delayed or impaired bone healing, and osteoarthritis still represent a social, financial, personal burden for affected patients society. Fully humanized in vitro 3D models of cancellous tissue are needed to develop new treatment strategies meet patient-specific needs. Here, we demonstrate successful cell-sheet-based process optimized mesenchymal stromal cell ...

Abstract This study aimed to evaluate, in vitro and vivo, the biocompatibility of experimental methacrylate-based endodontic sealers containing α-tricalcium phosphate (α-TCP) or nanostructured hydroxyapatite (HAp). Experimental dual-cure with addition α-TCP HAp, at 10%wt were formulated compared AH Plus (AHP). Cell viability was assessed by 3-(4,5-dimethyl-thiazoyl)-2,5-diphenyl-tetrazolium bro...
