Injectable nanoscale hydroxyapatite (nHA) systems are highly promising biomaterials to address clinical needs in bone tissue regeneration, due their excellent biocompatibility, bioinspired nature, and ability be delivered a minimally invasive manner. Bulk strontium-substituted (SrHA) is reported encourage growth by stimulating deposition reducing resorption, but there no detailed reports descri...
Bone is the most implanted tissue after blood. The major solid components of human bone are collagen (a natural polymer, also found in skin and tendons) and a substituted hydroxyapatite (a natural ceramic, also found in teeth). Although these two components when used separately provide a relatively successful mean of augmenting bone growth, the composite of the two natural materials exceeds thi...
A series of novel 2-aminopyrimidine and 2-Substituted-4,6-diaminopyrimidine derivatives have been synthesized and their anti platelet aggregation activities were assessed against ADP and arachidonic acid- induced platelet aggregation in human plasma using light transmission aggregometry. None of the compounds showed satisfactory activity against the aggregation induced by ADP. However, satisfac...
Strontium-substituted Ca10(PO4)6(OH)2 hydroxyapatite (HAp) powders, with Sr wt% concentrations of 2.5, 5.6 and 10%, were prepared by a solid-state synthesis method. The chemical composition the samples was accurately evaluated using inductively coupled plasma (ICP) spectroscopy. morphology analyzed via optical microscopy, while structural characterization achieved through powder X-ray diffracti...
