The calcium phosphate composite octacalcium / calcite was obtained at pH 5–7 from the CaCO 3 /Ca(H 2 PO 4 ) aqueous suspension in a galvanostatic mode current density of 20 mA/cm for min. Drying 80 °C without precipitate maturation stage led to powder formation consisting brushite, and small amount phosphate. Prolonged air months hydrolytic transformation brushite into stabilized by calcite. us...

The title Ni(II) complex, [Ni(C(7)H(4)BrO(2))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)], is centrosymmetric. It contains two 2-bromo-benzoate (BB) ligands, two nicotinamide (NA) ligands and two water mol-ecules, all of them being monodentate. The four O atoms in the equatorial plane around the Ni atom form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordinati...

UNLABELLED To understand early mineralization events, we studied living murine calvarial tissue by Raman spectroscopy using fibroblast growth factor 2 (FGF2)-soaked porous beads. We detected increased levels of a transient phase resembling octacalcium phosphate in sutures undergoing premature suture closure. INTRODUCTION Several calcium phosphates have been postulated as the earliest inorgani...

Formation of hydroxylapatite through the precipitation and evolution of calcium phosphate precursor phases under varying conditions of temperature (25–90 °C), pH (6.5–9.0), and calcium to phosphorus ratio (1.0, 1.33, 1.5, and 1.67) comparable to those found in many sediments and soils were studied. The products of low-temperature precipitation were analyzed by ex situ X-ray diffraction and SEM,...

BACKGROUND Amelogenin is required for normal enamel formation and is the most abundant protein in developing enamel. METHODS Amelx+/+, Amelx+/- , and Amelx-/- molars and incisors from C57BL/6 mice were characterized using RT-PCR, Western blotting, dissecting and light microscopy, immunohistochemistry (IHC), transmission electron microscopy (TEM), scanning electron microscopy (SEM), backscatte...
