Research ArticleOpen accessIn the abstractSimultaneous Presence of Growth and Remodeling in the Bone Adaptation TheorySeyyed Amir Hooshiar Ahmedi, Gholamreza Rouhi, Hamidreza Katouzian, Seyyed Ali Hooshiar AhmediMechanical forces acting on bone during growth affect their final shape and strength. Mechanoregulation of bone growth is maybe recognized in embryogenesis, and also in the adaptation of the adult skeleton to changes in mechanical loading. By combining equations describing bone remodeling and growth with an iterative finite element analysis, a computational model to simulate the simultaneous effects of bone … …American Journal of Applied Sciences, Vol. 6, Issue 2 · 28 Feb 2009 · 7,166 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComposite Scaffolds for Bone Tissue EngineeringMin WangBiomaterial and scaffold development underpins the advancement of tissue engineering. Traditional scaffolds based on biodegradable polymers such as poly(lactic acid) and poly(lactic acid-co-glycolic acid) are weak and non-osteoconductive. For bone tissue engineering, polymer-based composite scaffolds containing bioceramics such as hydroxyapatite can be produced and used. The bioceramics can be either incorporated in the scaffolds as a dispersed secondary phase or … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 7,355 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNanocrystalline Powders of Alkaline-Earth Phosphates as Precursors for BioceramicsParhi Purnendu, A. Ramanan, Alok R. RayBone is a nanocomposite made of calcium phosphates and collagen. Collagen has a typical fibrous structure, with diameter ranging from 100 nm to 2 μm. It is suggested that calcium hydroxyapatite, Ca10(PO4)6(OH)2 in the size range 5-50 nm embedded in the collagen framework provides mechanical strength to bone. Among calcium phosphates, apatites are found to be the most suitable for … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 6,543 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordFabrication of 3-D Porous Mg/Zn doped Tricalcium Phosphate Bone-Scaffolds via the Fused Deposition ModellingSamar Jyoti Kalita, Melissa FergusonThree dimensionally interconnected porous resorbable beta-tricalcium phosphate (β-TCP) ceramic scaffolds were developed using the indirect fused deposition modelling process. β-TCP was doped with Mg and Zn, separately, to improve its sintering kinetics and facilitate fabrication of viable porous scaffolds. Effects of Mg and Zn on sintering kinetics and densification of β-TCP were studied. Fabricated porous scaffolds were tested for their … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 2 · 30 Jun 2006 · 6,926 accessesView PDF Cite
