Background: Nowadays, E-learning is considered as a hot topic in higher education. This study aimed at investigating the effectiveness of virtual training of Islamic culture and civilization course on attitude, learning, and satisfaction of students in University of Medical Sciences in Tehran. Methods: In this quasi-experimental study with two groups, we studied 107 students who took the Islamic culture and civilization course in the second semester of academic year in 2014 -2015. 50.47% of them were Medical students (19.62% face to face, 30.84% virtual) and 49.53% of them were nursing students (21.50% face to face, 28.04% virtual). In the intervention group, 63 students received virtual training using university education system, and in the control group, 44 students received face to face training. In both of the groups, the degree of learning was examined using a written test. A questionnaire was used in order to investigate satisfaction with the teaching method and attitude. The reliability of the researcher-made attitude measurement questionnaire was confirmed using Cronbach's alpha (0.89) and its validity was confirmed through content validity. The Data was analyzed using SPSS software, version 16 and using T-tests. The significance level was set at 0.05. Results:The results showed that the two groups had a significant difference in terms of attitude (P < 0.001). The students were also more satisfied with the virtual training (P < 0.006). The rate of learning between the students of virtual and face to face training groups didn't show any significant difference (P < 0.199). Conclusions: Students were more satisfied with the virtual training method and they had a positive attitude towards the virtual training, but the rate of learning was similar in both of the methods. Therefore, it is recommended to use the virtual training courses as complementary courses in the face to face training methods.
Background: nutritional factors might affect the number and function of immune cells for instance the production of cytokines and immunoglobulins. Ramadan fasting is intermittent abstinence from eating and drinking for almost four weeks. Aim: The present study aimed to investigate the influence of intermittent fasting on serum IgA, salivary IgA (sIgA), interleukin (IL)-17, and IL-22 levels. Methods: 40 healthy men aged 19–29 years were evaluated before and during the fourth week of Ramadan fasting for IgA levels by the nephelometric method as well as salivary IgA (sIgA), IL-17, and IL-22 amounts using enzyme-linked immunosorbent assay (ELISA). Results: serum IgA levels reduced significantly at the end of Ramadan fasting (225.8 ± 87 vs. 196 ± 70 mg/dl) (p-value<0.001); however, sIgA amounts did not differ between before and the last week of Ramadan. Serum IL-17 reduced significantly (2.93 ± 1.51 vs. 2.17 ± 1.33 pg/ml) (p-value = 0.006) whereas IL-22 levels remained approximately unchanged. Summary: four weeks of intermittent fasting during Ramadan reduced the serum levels of IgA and IL-17 but did not affect the production of sIgA and IL-22. These findings indicate a limited impact of intermittent fasting on mucosal immunity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
