Injectable calcium phosphate hydraulic cement (CPHC) is a new bone substitute family. This study aimed to evaluate the use of CPHC in surgical periodontitis-simulating defects in a dog model. CPHC was obtained by adding powder mixtures of different calcium ...
NOVELTY - The bone substitute is made in one piece from cement phosphocalcium materials consolidated chemically at low temperature and in presence of water. USE - In medicine, as artificial bone graft. ADVANTAGE - Macroporous structure promotes resorption ...
The invention concerns microgranules produced from calcium phosphate materials. The invention also concerns a method for producing said microgranules. The inventive microgranules are characterised by a very narrow particle size distribution. ...
Unambitious syntheses of D-ribose 2-phosphate, 3-phosphate, 4-phosphate, 2,3-diphosphate, 3,4-diphosphate, 2,4-diphosphate, cyclic 2,3-phosphate, cyclic 3,4-phosphate, and cyclic 2,4-phosphate are described. Their 1H- and 31P-NMR data as well as their equi ...
The incommensurately modulated structure of K3In(PO4)(2) has been solved and refined. The origin of the modulation relates to the ordering of K cations within the hexagonal close packing of the PO4 anions. The driving forces for the modulation of the other ...
Structure and morphology of solid particles in precipitation from aqueous solutions correlate with formation (solution) conditions and thus reflect the growth mechanism. Calcium phosphate precipitation obtained from dilute aqueous solutions at room and bod ...
The cement for surgical purposes includes three components. The first component includes beta tertiary calciumphosphate beta-Ca3(PO4)2(beta-TCP) particles; and monocalcium phosphate Ca(H2PO4)2(MCPA) or monocalcium phosphate monohydrate Ca(H2PO4).H2O (MCPM) ...
Calcium phosphate precipitation obtained from aqueous solutions at room and body temperatures and pH 5.5-7.5 were investigated by high-resolution transmission electron microscopy (HRTEM), transmission electron diffraction, scanning electron microscopy (SEM ...
DNA-calcium phosphate co-precipitates arise spontaneously in supersaturated solutions. Highly effective precipitates for transfection purposes, however, can be generated only in a very narrow range of physico-chemical conditions that control the initiation ...
The gene therapy approach presented in this protocol employs a polymer encapsulated, xenogenic, transfected cell line to release human ciliary neurotrophic factor (hCNTF) for the treatment of Amyotrophic Lateral Sclerosis (ALS). A tethered device, containi ...
