PDF Influence of Er:Cr;YSGG laser Desensitization on SBS of resin cement to dentin
...Show More Authors

Background: Crown preparation of vital teeth involve the removal of a sound tooth structure, and when enamel removed this lead to exposed dentin with an   increase in the number of open dentinal tubules also the diameter of dentinal tubules will increase, furthermore lead to increase movement of fluids inside the tubules all that causes post preparation sensitivity. The aim of this study is to evaluate the effect of desensitizing by Er:Cr:YSGG laser on shear bond strength of prepared tooth and resin cement. Materials and methods: Thirty sound maxillary premolars, grouped into three groups(n=10). Group A is the control group, group B irradiated by Er:Cr:YSGG laser with (0.25 W, 20 Hz, 10%water and air), group C irradiated by Er:Cr:YSGG laser with (0.5 W, 20 Hz, 10% water and air). Results: SEM examination showed complete occlusion of opened dentinal tubules after laser irradiation of both groups that irradiated with laser. Statistical analysis showed significant increase in surface roughness in group B and C. SBS was significantly increase in group B with no significant increase in group C. Conclusion: Er:Cr:YSGG laser can occlude open dentinal tubules without and adverse effect on the retention of the restoration, on the contrary it increase bonding strength. And this increasing was significant in group B with (0.25W, 20 Hz, 10 % water and air). suggestion: so the parameters used in group B (0.25 W, 20Hz, 10 % water and air) is recommended for desensitizing prepared tooth and induce enhancement to the bonding strength of resin to tooth surface.

Synthesis and Charactrization of New Schiff Base Derived from PVA and Erythroascorbic Acid Derivative and Study Its Effect on the Activity of ACh Enzyme (In Vitro)
...Show More Authors

Schiff base derived from PVA and Erythroascorbic acid derivative (pentulosono-ɣ-lactone-2, 3-enedianisoate) was synthesized and characterized by Thin Layer Chromatography (TLC) and FTIR spectra, aldehyde was also characterized by (U.V-Vis), 1HNMR, 13CNMR and mass spectra. The inhibitory effect of prepared polymer on the activity of human serum Cholinesrerase has been studied in vitro. The polymer showed a remarkable activity at low concentration (4.5*10-3 – 4.5*10-8 M).

Risk of non-compliance and its impact on the profitability of Islamic banks: (Applied res earch in the Islamic Cooperation Bank)For the years (2016-2012)
...Show More Authors

This research deals with the risks of non-compliance and its impact on the profitability of Islamic banks. Research variables were measured and analyzed as the risk of non-compliance as an independent variableand profitability as a dependent variable. The profitability was measured by three indicators ((rate of return on assets, rate of return on equity and rate of return on Total deposits)) The results of the research showed a significant relationship between the risk of non-compliance and the rate of return on assets and rate of return on total deposits, while there was no relationship between the risk of non-compliance and rate of return on ownership. The research recommended that the senior management of the Islamic Investment Bank s

Mechanism of Immunotherapeutic and Anticancer Effects of &lt;i&gt;Moringa peregrina&lt;/i&gt; Seed Extract on Non-Small-Lung Cancer, NCI-H460, Cell Line
...Show More Authors

ory and cytotoxic activities of M. peregrina seed ethanol extract (MPSE). Based on using gas chromatography-mass spectrometry analysis MPSE is rich in flavonoids, isothiocyanate, tocopherols, triterpenoids, and phenolics compounds. The immunomodulatory effect of MPSE was determined on whole blood and polymorphonuclear (PMNs) cells and macrophages. The in vitro antiproliferative effect was determined on the non-small-cell lung cancer, NCI-H460, cell line. Real-time quantitative PCR and flow cytometry were used to determine the expression of apoptotic genes in the MPSE-treated NCI-H460 cells. MPSE significantly (p < 0.001) suppressed whole blood, PMN cells and macrophage ROS production with IC50 values of 40.3 ± 0.3, 33.0 ± 0.6, and 26.1 ±

  The research dealt with the design of the cost accounting system for the transport service and its Role in improving the efficiency of pricing decisions through the application of the cost system based on ABC activities. The main activities were defined and cost guides were to measure the cost of each service and to determine the cost of each service for the purpose of providing management with appropriate information and pricing decisions The problem of research in the lack of adoption by some public companies in the service sector on the cost accounting system to calculate the cost of service as well as the lack of identification of productive activities and service activities and therefore cannot make the appropriate decision t
