Abstract
Background: Vitamin D plays critical role in the development and bone stability, cell proliferation and differentiation. The aim of this study was to determine the serum levels of vitamin D and its affecting factors in infants aged 2 to 6 years in Kermanshah.
Methods: This cross-sectional descriptive study was performed in 32 health centers of Kermanshah on 389 children from 2 to 6 age, between 2014-2015. The questionnaires were distributed by verbal and written consent from parents of children and characteristics of them and type of their nutrition were recorded. The height and weight of infants were measured and recorded using the Sika scales with minimal coverage. The serum vitamin D levels were analyzed by ELISA method and the data were analyzed using SPSS v. 20 software.
Results: In this study, from 389 children 180 (46.3%) were female and 209 (53.17%) male. The results showed, 8.7% of infants had severe deficiency and 49.1% and 42.2% had insufficient and normal levels of vitamin D respectively. The highest mean serum vitamin D level was reported in summer, and there was a significant relationship between serum vitamin D levels with age, height, weight, and exposure to sunlight (p<0.05).
Conclusion: In this study, due to the high deficiency of vitamin D and its importance in children's growth and health, parents should be notifyed about the importance of this vitamin and also the necessity of enrichment of food in the health program.

Abstract
Background: Graphene chips are insoluble forms of graphene. Graphene is highly reactive and has no biocompatibility, but after oxidation, it becomes water-soluble. Graphene oxide (GO) is applied in biomedical, including gene and drug transfer, biomedical imaging, biomedical sensors, and antibiotics. Staphylococcus aureus is a gram-positive bacteria and is the most important species in Staphylococcus genus. Regarding the resistance of bacteria, biocompatible materials as antibiotics are important. The purpose of this study was to evaluate the antimicrobial properties of GO nanoparticles on Staphylococcus aureus.
Methods: GO was produced using Homer method. In this study, after bacterial culture (hospital and standard), antimicrobial effect of GO alone and with conventional antibiotics, halo diameter test, and spectroscopy method was measured. MBC and MIC were used to measure the effects of different specimens
Results: The results of this experiments showed that the GO decreased bacterial growth. Also, the results of treatment with GO and antibiotics showed a synergic effect. Statistical analysis of data obtained from synergism of erythromycin and gentamicin antibiotics was significant.
Conclusion: Due to the resistance of bacteria, the production of new antimicrobial agents has always been considered. Since GO improves the inhibitory effect of antibiotics and given that the cost of its production is relatively economical, it seems that graphene oxide can be used as a new drug compounds.
