Education in medical sciences also needs a fundamental change in order to improve the level of education by using modern teaching methods. Using videos during teaching makes students more alert and more motivated and focused on the subject. Since Mashhad University of Medical Sciences is one of the mother universities of the country and the center of educational technology and according to the listed advantages, a study was designed to design, implement educational topics in the form of videos and in the theory classroom for laboratory science students. To be displayed.

 44 laboratory science students were considered as the target group and participated in this scholarly study. The film was designed at the University Study Center and in the classroom, pre-test students consisting of 4 four-choice questions were first taken and the film was screened and then the test post was taken. At the end of the second session, a survey form consisting of 9 questions was given to the students and finally the test and survey results were analyzed with SPSS 21.

 The correct questions answered in the post-test were more than the pre-test, which was a significant level for the first question (p = 0.03) and the next three questions (p <0.001), respectively. Also, the number of wrong questions answered in the post-test was significantly reduced (p <0.001). Surprisingly, almost 80% of students expressed little or no interest in continuing this teaching process.

Despite the fact that the students' scores in the post-test were significantly better than the pre-test, but most students expressed little or no interest in continuing the teaching process using the film.

Allium hirtifolium (Persian shallot) belongs to the Alliaceae family. Recently, the ethanolic extract of Persian shallot was shown to have significant activity against some of the important clinical pathogens. This study has been assessed the in vitro antibacterial potency of ethanolic extracts of Persian shallot (Iranian Moosir) combined with common antibiotics against five clinically important antibiotic-resistant pathogens.  Antibacterial activities determined through disk diffusion. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were evaluated by the broth microdilution method for the extract and selected antibiotics. Finally, the checkerboard technique applied for evaluation of the combined effect of the extract and antibiotics.  The MICs of the extract and antibiotics ranged from 4 to 16 mg/mL and 4 to 128 µg/mL, respectively. The MBCs of the extract and antibiotics varied from 8 to 16 mg/mL and 8 to 128 µg/mL, respectively. The results of the checkerboard technique showed that Amikacin and Trimethoprim/sulfamethoxazole have synergistic effects, but Levofloxacin, Imipenem, and Vancomycin have antagonistic impacts in combination with the extract on all isolates.  It is suggested by the findings of this study which the in vitro application of Persian shallot extract combined with Amikacin and Trimethoprim/sulfamethoxazole. The mentioned combinations can inhibit the growth of five clinically significant antibiotic-resistant pathogens effectively.

Lack of nutritional knowledge is one of the most important reasons for nutritional problems and consequently im proper practice, which can lead to several complications. The aim of this study was to assess the knowledge, attitude, and practice of urban and rural households toward principles of nutrition in Neyshabour. This cross-sectional study investigates the knowledge, attitude, and practice of urban and rural households towards principles of nutrition in Neyshabour. The sampling method at households' level was single stage cluster sampling with equal size clusters. The incumbent data was collected by a structured questionnaire and through the interview with the eligible subject in each household. A total of 385 households were selected as overall sample size. Around 70% of households were aware of food groups. About 40-70% had correct knowledge about the roles of food groups. Most of the households had accurate knowledge about the reason for food eating. Knowledge, attitude, and practice levels of households toward principles of nutrition weremoderate and good. The results of this study can be used for proper intervention for improving health society.

Failure to thrive (FTT) is a common underlying condition in patients with Congenital diaphragmatic hernia (CDH). The aim of current study was to evaluate nutritional status and growth pattern in CDH patients. In current study, we investigated a total of 146 CDH patients who had undergone surgery in Dr. Sheikh Hospital, Mashhad, Iran between April 2006 to November 2013. Due to inaccessibility or lack of cooperation by some parents, 61 cases completed the study. Demographic and anthropometric data along with postoperative complications were taken into consideration. Among the 61 studied cases, 32.7% had died during the initial 6-months after surgery. The mean age of participants was 24.21 ± 30.26 months. According to Z-score classification of weight for height following surgery, 7.3% had severe malnutrition, 4.8% moderate malnutrition and 24.3% mild malnutrition while 51.2% were normal. While current evaluation indicates that the majority of subjects were in the normal range. Most children with congenital diaphragmatic hernia had a normal growth following surgery; however, few cases experienced a reduced growth rate in the early years of their life. Highlighting the need for additional calories to prevent FTT and other complications are recommended.

Aflatoxin contamination of agricultural crops leads to health hazards and detrimental to the economy. Despite enhanced processing, handling and storage, it remains an issue in the peanut industry. An effort was made to investigate the efficacy of corn zein coating combined with thymol and carvacrol as the edible coating may extend aflatoxinproduction. Analysis of aflatoxins B1, B2 and total were performed for 11 treatments on coated and uncoated peanuts stored at room temperature for 90 days. Treatments were included zein, thymol (500, 1000, 1500 ppm), carvacrol (5000, 10000, 15000 ppm), incorporating thymol and carvacrol at three different concentrations and control. Significant differences between coated and uncoated treatments were observed (p<0.05). The mean of aflatoxins B1, B2 and total in treatments with the highest concentration of antioxidant had increased between baseline and 90th day. While in other treatments the trend was decreasing compared to the control. Coating containing zein showed the best results in terms of preventing aflatoxin formation. So it can be recommended as a suitable coating for peanut, promoting their health benefits.
