BackgroundInorganic antibacterial factors provide high bacterial resistance and thermal stability. Inorganic nanomaterial consists of modern formulation, biological, chemical, and physical properties produced on the basis of their function and influenced by their nano scales, the reason for which they have become very popular. The antibacterial effect of Cadmium Oxide Nanoparticles on Staphylococcus Aureus has been studied for the first time in this research because of their resistance to antibiotics.Materials and methodsDifferent concentrations consist of 10 μg/ml, 15 μg/ml, and 20 μg/ml have been provided and their effects were studied in the agar and broth against the foregoing bacteria. Needless to say, the optimization of their non-microbial effect in variable times, pH, and temperatures of exposure was analyzed.ResultsThe results represented that there is a direct association between the nanoparticles applied dosage and the restrain effect augmentation of applied dosage results in increase in restrain effect. In the study of environmental factors (pH and temperature), the results are in line with the inherent physiology of the bacteria; however, there was a significant decline in the number of analyzed bacteria cells due to the “Double Effect” of nanoparticle-pH variations as well as nanoparticle-temperature variables. In the very study, the promotion of Cadmium Oxide nanoparticles concentration leads to the elevation of antimicrobial feature and the reduction of bacteria growth rate is consistent with the other surveys about the nanoparticles effects on microorganisms to be more specific, one can come to this conclusion that the presence of nanoparticles prompts cellular destruction.ConclusionIn the recent study, by elevation in Cadmium Oxide nanoparticles concentration, the antimicrobial property augments and the bacteria growth rate declines, that are in line with other researches about the nanoparticles effect on microorganisms.

For many centuries, the metals are used as the antibacterial factors. Whereas, the nanoparticles are mostly heavy metal oxides, they have a high tendency to interact with biological molecules and develop the deactivation or elimination of the virus or bacteria. In the present study, the antibacterial effect of Cadmium Oxide nanoparticles on Pseudomonas Aeruginosa bacteria was analyzed which are considered some sort of resistant bacteria against antibiotics now. The aim of his study was to investigate the antibacterial properties of onekind of nno-specimen (cdo) against Pseudomonas Aeruginosa. Our study was research perusal. In the first study, the optical density of Pseudomonas Aeruginosa culture was observed in the presence of 5, 10, 15µg/ml. in the scond study, 600nm of Pseudomonas Aeruginosa was separately exposed to nanoparticles at 37° c in water. In third study, we studied thew growth of Pseudomonas Aeruginosa in solid medium with and without nanoparticles. The results represented that there is a direct relation between the nanoparticles applied dosage and the restrain effect-augmentation of applied dosage results in restrain effect increase. In the study of environmental factors (pH and temperature), the results are in line with the inherent physiology of the bacteria, however, there was a significant decline in the number of analyzed bacteria cells due to the Double Effect of nanoparticle-pH variations as well as nanoparticle-temperature variations. In the present study, enhancement in 474 Bahareh Salehi, Sedigheh Mehrabian and Abbas Akhavan Sepahi Cadmium Oxide nanoparticles density leads to the elevation of antimicrobial feature and the reduction of bacteria growing speed which is in line with the other surveys about the nanoparticles effects on microorganisms. It could be interpreted that, in the presence of nanoparticles, cellular destruction speeds up.

Background: In the last few years, facial rejuvenation has moved to less invasive or non-surgical techniques because their effects are visible immediately after the treatment, they have shorter recovery time and less pain and patients can go back to their normal life on the same day. Rhinoplasty is a cosmetic procedure that is very difficult to master. The main goal of rhinoplasty is anatomical preservation. One of novel technique for nose remodeling is laser therapy. In this study, the authors evaluate the efficacy of the endolift laser as a technique for nose remodeling.Methods: A total of eight patients were enrolled and were submitted to endolift laser therapy. The outcomes were measured by photography, three blind board-certified dermatologists assessment, and patients satisfaction. Results:Our results showed that endolift Laser as non-surgical nose remodeling technique is a safe and effective method. Clinical assessment of the physician showed a significant improvement at 6-months follow-up. Also, the patient satisfaction rate was higher in the enrolled participates. Also, no severe side effect was reported. Conclusion:The endolift laser technique is practicable, effective, and safe method for non-surgical nose job and has no major complication.
