Corrosion resistance evaluation of HVOF produced hydroxyapatite and TiO2-hydroxyapatite coatings in hanks' solution
(2018-01-01)
The electrochemical behavior of HVOF produced hydroxyapatite (HA) and 80HA-20TiO2 coatings were investigated using electrochemical techniques in natural aerated Hanks' solution in the presence and absence of bovine serum ...
Antifungal applications of Ag-decorated hydroxyapatite nanoparticles
(2013-08-19)
Pure hydroxyapatite (HA) and hydroxyapatite decorated with silver (HA@Ag) nanoparticles were synthesized and characterized. The antifungal effect of HA@Ag nanoparticles in a distilled water solution was evaluated against ...
Repair of the anophthalmic cavity of rats with synthetic hydroxyapatite
(Associação Brasileira de Divulgação Científica (ABRADIC), 1997-10-01)
We placed spheres of synthetic hydroxyapatite (calcium chloride combined with sodium phosphate) in the eviscerated or enucleated orbital cavity of rats in order to evaluate the biocompatibility of this material with the ...
Porous hydroxyapatite scaffolds by polymer sponge method
(2009-02-02)
This study aimed to develop porous hydroxyapatite scaffold for bone regeneration using the replica of the polymeric sponge technique. Polyurethane sponges were used with varying densities to obtain the scaffolds. The results ...
The use of hydroxyapatite and autoaenous cancellous bone grafts to repair bone defects in rats
(Churchill LivingstoneEdinburghEscócia, 2005)
A comparative thermoluminescence and electron spin resonance study of synthetic carbonated A-type hydroxyapatite
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Intensity of the 150 degrees C thermoluminescence peak of beta-irradiated carbonated synthetic A-type hydroxyapatite is approximately 12 times higher than that of the noncarbonated material. Deconvolution of the glow curve ...
Hydroxyapatite coating deposited on grade 4 titanium by plasma electrolytic oxidation
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2014-11-01)
The present study reports the deposition of coating using Plasma Electrolytic Oxidation (PEO) onto grade 4 titanium to produce novel surface features. Samples were treated in an electrolytic solution of calcium acetate and ...
Femur bone repair in ovariectomized rats under the local action of alendronate, hydroxyapatite and the association of alendronate and hydroxyapatite
(Wiley-Blackwell Publishing, Inc, 2009-10-01)
P>An evaluation was made of the local action of alendronate sodium (A), hydroxyapatite (HA) and the association of both substances (A + HA), in different molar concentrations, on the femur bone repair of ovariectomized ...
Comparison of crystallinity between natural hydroxyapatite and synthetic cp-Ti /HA coatings
(ABM, ABC, ABPol, 2005-06-01)
Commercial purity titanium (cp-Ti), and some of its alloys are important materials in the medical field because of their excellent biocompatibility and mechanical properties. Recently a simple chemical method to induce ...
Effect of DOPA and dopamine coupling on protein loading of hydroxyapatite
(Taylor & Francis Ltd, 2016-01-01)
Hydroxyapatite (HA) is a promising carrier material for oral delivery of biomolecules such as proteins and drugs. Ways to increase the loading of such molecules on HA will lead to better nanomedicine. This study reports ...
