...Show More Authors

Abstract

Digital repositories are considered one of the integrated collaborative educational environments that help every researcher interested in developing the education and educational process. The learning resources provided by the repositories are suitable for every researcher, so digital information can be stored and exchanged by ensuring the participation and cooperation of researchers, teachers, and those who are interested, as well as curricula experts, teachers, and students, to exchange each other’s experiences in constantly updating that information as a reason for developing their performance in education. This reveals the importance of the role of educational digital institutions by providing and developing repositories for preserving research and studies of interest in the educational process and of interest to teachers in the primary stage, where the primary stage teacher can benefit from digital deposits in providing and building the preparation of classes and lessons of an electronic nature, as well as his development in all his roles of methods Teaching, the scientific side, the educational, and human side. Therefore, teachers, researchers, and those interested in the educational process should be urged and encouraged to develop their performance in teaching by designing and building educational digital repositories in all different branches of science. The research reached that the success of the educational process depends on a group linked to the elements of the educational process, including the teacher and his role in the stage of elementary schools through their development. The searcher recommended providing the material requirements and capabilities necessary for the application of digital repositories in the educational process.

The Synergistic Effect of Zinc, Coumestrol, Genestein and Daidzein on Proinflammatory Cytokines Production and Receptor Activator of NFκB Ligand Expression that Implicates in Bone Resorption
...Show More Authors

Several observations have showed the synergistic effect of nutrients elements and phytoestrogens on bone resorption elimination. Zn is one of the trace elements found to increase the stimulatory effect of phytoestrogens including genestein, coumestrol and daidzein on bone formation; however the synergistic modulation of Zn, genestein, coumestrol and daidzein on proinflammatory-producing T-cells and receptor  activator of NFκB ligand (RANKL) expression that implicated in osteoclast formation is still open area to debate. This study found that Zn enhanced the inhibitory effect of genistein, daidzein and coumestrol on TNF-α expression; however the same effect was shown with daidzein on IL-1β expression while there is no furthe
