Tissue engineering strategies to construct vascularized bone grafts are now attracting much attention. Strontium-hardystonite-Gahnite (Sr-HT-Gahnite) is a strong, highly porous, and biocompatible calcium silicate based bio-ceramic that contains strontium and zinc ions. Adipose derived stem cells (ASCs) have been demonstrated to have the ability in promoting osteogenesis and angiogenesis. In thi...

INTRODUCTION Sealers based on tricalcium silicate cement aim at an interaction of the sealer with the root canal wall, alkalinity with potential antimicrobial activity, and the ability to set in a wet field. The aim of this study was to characterize and investigate the properties of a new tricalcium silicate-based sealer and verify its compliance to ISO 6876 (2012). METHODS A new tricalcium s...

in order to study the effect of fertilizer management on summer savory production, a field experiment was conducted at the agricultural research station, college of agriculture, ferdowsi university of mashhad, iran during growing season of 2009. a randomized complete block design with three replications was used. treatments included: 1) nitroxin biofertilizer 2) phosphate solubilizing bacteria ...

1. Three established methods for immobilization of ligands through primary amino groups promoted little or no attachment of NAD(+) through the 6-amino group of the adenine residue. Two of these methods (coupling to CNBr-activated agarose and to carbodi-imide-activated carboxylated agarose derivatives) resulted instead in attachment predominantly through the ribosyl residues. Other immobilized d...

In order to ascertain optimum conditions for biocatalytic processes carried out in vitro, we have designed a bio-opto-electronic system which ensures real-time compensation for depletion of adenosine triphosphate (ATP) in reactions involving transfer of phosphate groups. The system covers ATP concentration range of 2-48 μM. The report demonstrates feasibility of the device operation using apyra...

direct electron transferring of glucose oxidase was investigated   on reduced graphene and graphene oxide templates. the direct electrochemistry   glucose oxidase on   graphene showed a cyclic voltammograms corresponding to the fad/fadh 2   redox couple with an anodic, cathodic and formal potential of -430, -460 and   -445 mv, respectively in 0.1 m phosphate buffer solution and air saturated   ...

A pot experiment was carried out on hybrid drumstick PKM 1 added with inorganic and organic fertilisers. Seeds of hybrid Drumstick PKM1 were sown in the plastic pots in glass house condition. Single inorganic fertilizer, phosphate solubiliser and bio organic fertilizer as well as in different combinations were applied to the pots. Data revealed that plant height, fresh and dry biomass, moisture...
