The R&D of ceramic biomaterials has extensively progressed in Japan since commercial production of calcium phosphates of hydroxyapatite and β-tricalcium phosphate, A-W glass, chemicalsand SBF (simulated body fluid)-treated metals, and yttria-stabilized zirconia for dental and medical applications. The centers of R&D excellence in Japan consist of universities and national research institutes in...

Background: Some types of implants used for orbital implantation have side effects and complications. In this study we have evaluated beta-tricalcium phosphate (ß-TCP: ChronOS) granules as an orbital implant. Methods: Eighteen rabbits randomly allocated to four groups. Right eye enucleation performed in groups I to III followed by filling with autologous bone particles (n=5), a mixture of autol...

Objective- To determine the effect of selected bone graft on the compression properties of radialbone in rabbit.Design- Experimental in vivo study.Animals- A total of 45 adult male New Zealand white rabbits.Procedures- The rabbits were anesthetized and a one-cm-full thickness piece of radial bone wasremoved using oscillating saw in the all rabbit. The rabbits were divided into 5 groups on theba...

native phosphate solubilizing bacteria (psb) were isolated from four areas (ankober, keyt, mehalmeda and molale) of ethiopia to study their effect on releases of soluble phosphorus from insoluble p sources. the highest bacterial number was found at keyt (2.6103 g-1soil) and the least at molale (15 g-1soil). five efficient psb were selected for further study based on their ability in forming a ...

The role of soil-borne microalgae in the edaphic ecosystem is barely known, especially concerning their plant-growth-promoting traits, although they are used as biofertilizers. In this study, a microalgal strain isolated from soil cultivated with maize was evaluated an exogenous producer indole-3-acetic acid (IAA) potato dextrose broth—PD—and sugarcane molasses, or without tryptophan, and phosp...
