- چکیده انگلیسی: Introduction
Since nutrition, especially in childhood and adolescence is an important effect on intelligence and learning, so that malnutrition delayed to later periods of life, so that these people during the course of studies, will have many problems, this study was conducted to evaluate the effect of nutrition on student learning.
Materials and Methods
This study was a cross-sectional study that was conducted. The sample size was all students that studying in a boarding school in five district of Mashhad-Iran. The valid and reliable questionnaire, consisted of 19 questions and specialized feeding habits of the students. Data were analyzed with spss-13 software.
Results
90 students participated in the study guide. 48.9 % were second grade and 51.1 % were third grade of Junior High School. 24.4% of students in their grade point average were between was between 15-13; 65.6% were 15-18 and also 10% of them their grade point average were between 18-20. 67.8% of students said that they love so much sweetmeat and 61.1% of students with food, pickles and salt used as high. Results showed that 38.8% of students had used too much salt in food, and on the other hand, 27.8% of students had used salt moderate.
Results showed that students who had a grade average lower, the consumption of fish, red and white meat, green and orange vegetables and dairy products were lower than the other students (p <0.05).
Conclusion
Students who had better nutritional behavior (consumption of Breakfast, fruits and vegetables and dairy products were more than the other students) had higher average scores than other students.- انتشار مقاله: 27-12-1393

- چکیده:
- چکیده انگلیسی: A fast and facile electrochemical sensor for detection of important anti-cancer drug 5-fluorouracil (5-FU) is fabricated using a copper-nanoparticles decorated multi-walled carbon nanotube and chitosan composite modified electrode. Copper nanoparticles/multi-walled carbon nanotubes/ionic liquid/chitosan modified glassy carbon electrode (CuNPs/MWCNTs/IL/Chit/GCE) prepared by the consecutive coating of MWCNTs/IL/Chit nanocomposite on the GCE, followed by the electrodeposition of copper. Surface characteristics of the modified electrode were studied by scanning electron microscopy (SEM). The electrochemical capability of the fabricated modified electrode for the detection of 5-FU is examined by cyclic voltammetry, differential pulse voltammetry (DPV). The nano Cu decorated MWCNTs/IL/Chit/GCE is found to be efficient for the electrocatalytic oxidation of 5-FU. The peak current of the DPV exhibited a linear relationship against 5-FU over a wide concentration range of 1-110 µM with a low detection limit (0.15 µM). Additional, the sensor was successfully applied in biological fluid sample analysis.
