A novel, simple, sensitive and green ultrasonic-assisted liquid–liquid microextraction method based on a synthetic citric
acid–glycerol nanopolymer solution was used for the extraction of antioxidant acids (ferulic, cinnamic, gallic acid and rutin)
in five kinds of oil samples from vegetables. The synthetic nanopolymer from citric acid and glycerol with absolute molar
ratio was synthesized, and its specifications were characterized by (FTIR, DLS, GPC, AFM and NMR). Its solution as a
green extractor for oil samples was added to n-hexane containing analytes. Then, the extraction was speeded up by using
ultrasonic. After the extraction, phase separation (rich phase/n-hexane phase) was accomplished by using a centrifugation.
Rich phase in lower phase was removed by a micro-syringe and injected to reverse-phase HPLC with UV detector. Volume
of nanopolymer solution, concentration of nanopolymer, extraction time and temperature of ultrasonic bath were optimum
conditions and obtained by response surface methodology. This method has good linear calibration ranges between 0.7 and
1300 μg L−1, coefficients of determination (r2 > 0.9831) and low limits of detection between 0.05 and 0.81 μg L−1. This
method was successfully used to determine target analytes in oil samples of olive, almond, sesame, hazelnut and edible with
satisfactory inter–intraday precision and recoveries (93t.4–107.1%)..

Abstract
Acute respiratory infection is one of the primary diseases that causes high morbidity and mortality in children, especially in developing countries, where 70% of deaths are in Africa and Southeast Asia (1). . The latest statistics show that approximately 150 million new cases of pneumonia are diagnosed worldwide each year, more than 90% of which occur in developing countries and 30% of annual deaths in children under 5 years of age. Is (2). In Iran, several studies have been performed on selected populations of children with acute respiratory infections in different parts of the country, which have yielded different results, so an accurate statistical picture of the extent and importance of acute respiratory infections is not available (3). . Acute respiratory infection is often caused by a new invasion or abnormal release (development) of a specific pathogen into the airway, which in addition to the host defense also affects the incidence and severity of infection (4). , Microbiome refers to the overall microbial community and its biomolecules in a defined environment (5). It describes the fundamental role of microbiome in human health (6).
Research based on culture studies and, more recently, culture-independent methods have identified a microbial community in the lower respiratory tract of a healthy individual. (7).
Therefore, studying and informing about the prevalence of bacteria and viruses in pediatric uropharynx and also better understanding of bacterial colonization and their interaction, can be effective in predicting changes in bacterial ecology and design control strategies (including interference in colonization) . In particular, determining the rate of asymptomatic colonization with potential pathogens is important to predict the spread of the disease in the community and to design strategies for prevention and treatment. Therefore, respiratory infections in both developing and developed countries have a heavy economic burden on the family and society. Finally, considering the importance of respiratory infections in our country, in this study we try to investigate the prevalence and frequency of oropharyngeal microbiome in children under 6 years of age in Ilam by culture method and its relationship with the underlying variables to be evaluated. , And thus provide the necessary ground for further studies by researchers in the future

Abstract
Biofilm formation causes many serious problems in the treatment in infections disease. In addition, bacterial biofilms in hospitals cause contamination and great damage to the health system. Hence, the purpose of the available study was to investigate antibacterial effect of chlorhexidine (CHX) and hydrogen peroxide (H2O2) on gene expression in Enterococcus faecalis biofilm.

Abstract
Background: Environmental awareness and understanding of environmental issues are influential variables in environmental behaviors, and it is imperative for the community to educate on human behavior. It is only in the light of this type of training that many resolved environmental crises and sustainable development are realized. The purpose of this study was to determine the effect of education on promoting environmentally responsible behaviors of first grade high school students in Ilam in 2016.
Methods: This study was an empirical study that was done on female high school students in Ilam city in 2016. Data collection tool was a researcher-made questionnaire. Two girls' high schools were randomly selected from the first public high schools of Ilam and randomly assigned to the experimental (N= 165) and control (N= 165) groups. Educational intervention was designed and implemented in 5-sessions of 30-minutes including environmental concepts, waste production and recycling, air and water pollution, water and energy saving, sewage and disposal methods for the case group. One month after the intervention, students in both groups were evaluated. Data were analyzed with SPSS software using independent t-test, paired t-test, chi-square, correlation and regression.
Results: Despite the similarity of the groups in the mean scores of knowledge, attitude and responsible behavior before intervention (P>0.05), there was a significant difference in the mean scores of all variables between the two groups after the intervention (P<0.05).
Conclusion: Community education is an effective strategy to raise environmental information, Developing environmental sensitivity and beliefs and ultimately promoting responsible environmental behaviors among first grade female students.

Abstract
Overuse and inappropriate antibiotic prescription for acute respiratory infections (ARIs) are one of the major contributors to the current antibiotic resistance problem. Also, ARIs are one of the most common infections so that, they are of great importance and can play a very important role in mortality in children and adults due to their very widespread and rapid spread. So, the purpose of this study is to train physician communication skills with patients in order to reduce use of antibiotic and subsequently reduce antibiotic resistance, proper use of antibiotics in cases where it is necessary to use, reduce self-medication and ultimately reduce costs.
