Hypoxia Biomimicry to Enhance Monetite Bone Defect Repair
Tissue Engineering Part A, 2017Tissue hypoxia is a critical driving force for angiogenic and osteogenic responses in bone regeneration and is, at least partly, under the control of the Hypoxia Inducible Factor-1α (HIF-1α) pathway. Recently, the widely used iron chelator deferoxamine (DFO) has been found to elevate HIF-1α levels independent of oxygen concentrations, thereby, creating

Preparation and properties of tetracalcium phosphate–monetite biocement
Materials Letters, 2013Abstract The tetracalcium phosphate–monetite cement mixture was prepared by reaction milling of tetracalcium phosphate with the orthophosphoric acid ethanol solution. The presence of nanomonetite phase caused significant lowering of the pH value in cement paste during hardening.

Development of nanosilica bonded monetite cement from egg shells
Materials Science and Engineering: C, 2015This work represents further effort from our group in developing monetite based calcium phosphate cements (CPC). These cements start with a calcium phosphate powder (MW-CPC) that is manufactured using microwave irradiation. Due to the robustness of the cement production process, we report that the starting materials can be derived from egg shells, a ...

Monetite granules versus particulate autologous bone in bone regeneration
Annals of Anatomy - Anatomischer Anzeiger, 2015The aim of this study was to test bone tissue response to monetite granules in comparison with intramembranous autologous bone graft in a rabbit calvaria critical size defect model.Novel monetite granules were synthesized by thermal conversion of set brushite cement. Eight female New Zealand rabbits were used for this study. Two identical 10mm diameter

NEW POLYMORPH OF CaHPO4 (MONETITE): SYNTHESIS AND CRYSTAL STRUCTURE
Журнал структурной химии, 2016A novel form of anhydrous dicalcium phosphate CaHPO4 (monetite) is synthesized hydrothermally and characterized by single crystal X-ray diffraction. It crystallizes in the orthorhombic space group Ccm21 with a = 6.242(1) A, b = 6.994(2) A, c = 7.003(3) A, V = 305.73(16) A3 and it has four independent unit formulas in the unit cell (Z = 4).

Structure and Properties of Ceramics Based on Monetite and Nanodispersed Silica
Powder Metallurgy and Metal Ceramics, 2015Calcium–phosphate ceramics based on monetite and nanosized silica are produced by sintering at 500°C. It is established that phase changes and solid-phase reactions occur during sintering to form ceramics that contain β-calcium pyrophosphate (Ca2P2O7), calcium silicate (wollastonite, CaSiO3), and insignificant amount of β-tricalcium phosphate (Ca3(PO4 ...

Heterogeneous crystallization of calcium hydrogen phosphate anhydrous (monetite)
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2017Abstract The crystal growth of monetite (CaHPO 4 , DCPA), the least stable calcium phosphate has been investigated by the seeded growth method from solutions supersaturated exclusively with respect to this phase alone. The kinetics of crystal growth was measured at constant supersaturation at 37° C, pH 6.0.

The Biological Properties of Co‐Doped Monetite Are Influenced by Thermal Treatment
Journal of Biomedical Materials Research Part B: Applied BiomaterialsABSTRACTCalcium phosphates, notably monetite, are valued biomaterials for bone applications owing to their osteogenic properties and rapid uptake by bone cells. This study investigates the enhancement of these properties through Cobalt doping, which is known to induce hypoxia and promote bone cell differentiation.

Macroporous monetite scaffold for bone tissue engineering
2012Three dimensional scaffolds based on ceramics, polymers and or composites in combination with mesenchymal stem cells can be utilized to engineer tissues such as bone and cartilage [1]. One of the main limitations of 3D constructs is the mass transfer involved during in vitro culture which results in limited cell growth within the 3D construct.
