Effect of gold nanoparticles synthesis by plasma jet scheme on normal cell lines
...Show More Authors

New evidence on nanotechnology has shown interest in the creation and assessment of nanoparticles for cancer treatment. Worldwide, a wide range of tumor-targeted approaches are being developed to reduce side effects and boost the efficacy of cancer therapy. One strategy that shows promise is the use of metallic nanoparticles to increase the radio sensitization of the cancer cells while reducing or maintaining the normal tissue complication probability during radiation therapy. In this study, atmospheric plasma was created using argon gas to create Au NPs using the plasma jet scheme, and their ability to induce apoptosis as an anticancer mechanism was tested. Aqueous gold tetrachloride salts (HAuCl4·3H2O) ere used to produce gold nanoparticles. For conformations, various techniques were used to explore the characterization of Au NPs, included UV–Vis spectroscopy, X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM),). UV–vis spectroscopy showed a maximum absorption peak located between 520 and 530 nm. The peaks of XRD 2θ are observed at 38.8°, 44.47°, 64.4° and 77.17°. They correspond to the 111, 200, 220 and 311 crystalline levels respectively. The peak intensity (111) at 38.8° diffraction was maximum peak. the image of FESEM showed that the Au NPs which produced are irregularly shaped spheres with sizes ranging between 41-46 nm. The effect of nanoparticles on REF normal cell lines was studied to calculate cytotoxicity and the greatest rate of destruction of REF normal cell lines was 22.667% after incubation time 72 hour after exposure to the combination of irradiated gold nanoparticles-cisplatin with 50 Gray photon X-ray and 1 µg of cisplatin and the minimum was 0.7% after incubation time 24 hour after exposure to the combination of irradiated gold nanoparticles-cisplatin with 0.5 Gray photon x-ray and 0.025 µg of cisplatin. Its possible to enhance chemotherapy treatment by these nanoparticles, In the future these techniques will be possible to use for kill cancer cells, especially after showed low toxicity on normal cells.

Immediate and Delay Antimicrobial Activity of Three Disinfection Solutions on Gutta-Percha Cones as Routine Chair-Side Procedure
...Show More Authors

Objective: The antimicrobial efficacy of three disinfection solutions: 5.25% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) and Listerine mouthwash were investigated as routine chair-side gutta-percha (GP) disinfection reagents. Design: four groups of gutta percha points were contaminated with E. faecalis bacteria then disinfected by immersion in different solutions (5.25% sodium hypochlorite, 2% chlorhexidine gluconate, Listerine mouth wash and distilled water as control) after 1 and 7 days culturing periods. The antibacterial efficacy of these disinfection solutions was evaluated by using colonies per units (CPU) Methods: Forty GP cones (F3 Dentsply) were sterilized with ethylene oxide gas before immersed contamination within broth m

Design of a Kinematic Neural Controller for Mobile Robots based on Enhanced Hybrid Firefly-Artificial Bee Colony Algorithm
...Show More Authors

The paper present design of a control structure that enables integration of a Kinematic neural controller for trajectory tracking of a nonholonomic differential two wheeled mobile robot, then  proposes a Kinematic neural controller to direct a National Instrument mobile robot (NI Mobile Robot). The controller is to make the actual velocity of the wheeled mobile robot close the required velocity by guarantees that the trajectory tracking mean squire error converges at minimum tracking error. The proposed tracking control system consists of two layers; The first layer is a multi-layer perceptron neural network system that controls the mobile robot to track the required path , The second layer is an optimization layer ,which is impleme

Numerical study of single-layer and interlayer grating polarizers based on metasurface structures for quantum key distribution systems
...Show More Authors

Polarization is an important property of light, which refers to the direction of electric field oscillations. Polarization modulation plays an essential role for polarization encoding quantum key distribution (QKD). Polarization is used to encode photons in the QKD systems. In this work, visible-range polarizers with optimal dimensions based on resonance grating waveguides have been numerically designed and investigated using the COMSOL Multiphysics Software. Two structures have been designed, namely a singlelayer metasurface grating (SLMG) polarizer and an interlayer metasurface grating (ILMG) polarizer. Both structures have demonstrated high extinction ratios, ~1.8·103 and 8.68·104 , and the bandwidths equal to 45 and 55 nm for th

Three isolates of  P. aeruginosa were isolated from burnt patients. The ability of these isolates for adhesion and formation of slime layer were tested, the result showed that all isolates were able to adherence on the smooth surface. The sensitivity of  P. aeruginosa isolates for antibiotics were tested , all isolates were sensitive  to Gentamycin, Piperacillin and Amikacin Ciprofloxacin, and  resist to Tetracyclin, Amoxicillin, Cephalexine , Ceftriaxone. Ciprofloxacin and Amikacin were found effective against P. aeruginosa isolates with MIC values of 3.8 μg/ ml for  Ciprofloxacin  and 0.244 μg/ ml for Amikacin The antibacterial effect of Different concentrations of Aloe
