Background. Nowadays distance learning is a necessary measure under pandemic circumstances, therefore, it is important to find out mechanisms to improve its effectiveness. Objective is to increase the efficiency of practical classes’ results during distance learning. Methods. Sixty third course international EAs (specialty "222 Medicine", second master's level) were divided into two equal groups with two different teaching approaches of practical classes: control with classical one (material discussion followed by the practical skills implementation) and experimental with a changed indicated stages order. The data of 3 controls (pretest, intermediate test and posttest) during practical classes in the course of one semester were analyzed by criteria for non-normal distribution. Results. Pretest and posttest results were not significantly different in both tested and control groups within different performing level EAs (p>0.05). The data of intermediate tests were familiar in groups of EAs who permanently have either average (p>0.05) or insufficient grades (p>0.05), but increased in groups of EAs with constant low (p≤0,05) and high (p<0,05) scores. Conclusion. Our study showed that academic performance did not heavily depend on performed practical classes’ structure. However, the critical discussion of low- and high-performing EAs' mistakes lead to improvement of their understanding of nuances of gross specimen and slide description, in other words, the implementation of a number of special and general competencies enhancement. All in all, data showd that exit control results as well as final grades depended not so much on the educational approach, but on the EAs' self-study.

The study investigated the effects of out-door activities on students’ attitude towards learning of Physics in Senior Secondary School Physics in Ekiti State, Nigeria. The research design adopted in the study was Pretest-Posttest Quasi-experimental. The sample for the study was 150 Senior Secondary One (SSI) Physics students (this sample was divided into the experimental and control groups in ratio 1: 1 i.e. 75 in each group), selected through the multistage sampling technique from a total population of 7,852 SS I students offering Physics in all the 184 public Senior Secondary Schools in Ekiti State. The instrument used to collect relevant data from the subjects was Physics Attitudinal Scale (PAS). The reliability of the instrument was determined through the split-half method with the reliability coefficient of 0.83. Two null hypotheses were tested at 0.05 level of significance. The data collected were analysed using inferential statistics of t-test and Analysis of Covariance (ANCOVA). The results of the analyses showed that there was significant difference in the attitude of students to Physics in the experimental and control groups in favour of experimental group. Based on the findings of the study, it was recommended that non-conventional teaching approaches such as using out-door activities, should be introduced into the teaching of Physics in the nation’s secondary schools to reinforce the hitherto adopted conventional teaching method and Physics teachers should be encouraged to make use of these new teaching approaches.

<p>The ways in which task in classrooms has developed and proceeded have receive great attention in the field of language teaching and learning in the sense that they draw attention of learners to the competing features such as accuracy, fluency, and complexity. English audiovisual and audio recorded materials have been widely used by teachers and students, and have been the important resources of teaching and self-study. Nowadays, the environment we are living in is abundant with audio visual input and we as teachers ,thus, should be aware of the fact that environment can change students’ behavior towards language and language learning .What effects do these materials have on English speaking ability? The objective of this study is to find out whether there is difference in Iranian EFL learners’ accuracy in both audiovisual recorded (videos, movies ,etc.) and audio recorded tasks. For this purpose, 40 students of intermediate level were chosen and then were randomly assigned into two experimental and control groups each of which was under different listening tasks. (Audio visual- and audio only). Data analysis showed that the group which was trained under AV listening tasks showed different effects on students’ accuracy, compared to the other group positioned using audio recorded. Based on the results of this study, it is imperative that teachers consider the types of activities and methods that can have influence over language learners’ speaking ability.</p>

Conjugated linoleic acid (CLA) is a collective term for the positional and geometric isomers of a conjugated diene of linoleic acid (C18:2, n-6). The aims of the present study were to evaluate whether levels of hepatic α-tocopherol, α-tocopherol transfer protein (α-TTP), and antioxidant enzymes in mice were affected by a CLA-supplemented diet. C57BL/6 J mice were divided into the CLA and control groups, which were fed, respectively, a 5 % fat diet with or without 1 g/100 g of CLA (1:1 mixture of cis-9, trans-11 and trans-10, cis-12) for four weeks. α-Tocopherol levels in plasma and liver were significantly higher in the CLA group than in the control group. Liver α-TTP levels were also significantly increased in the CLA group, the α-TTP/β-actin ratio being 2.5-fold higher than that in control mice (p<0.01). Thiobarbituric acid-reactive substances were significantly decreased in the CLA group (p<0.01). There were no significant differences between the two groups in levels of three antioxidant enzymes (superoxide dismutase, glutathione peroxidase, and catalase). The accumulation of liver α-tocopherol seen with the CLA diet can be attributed to the antioxidant potential of CLA and the ability of α-TTP induction. The lack of changes in antioxidant enzyme protein levels and the reduced lipid peroxidation in the liver of CLA mice are due to α-tocopherol accumulation.

Introduction: The role of virgin coconut oil in the treatment of allergic rhinitis is controversial. Thus, the aim of the present study is to determine the effects of virgin coconut oil ingestion, in addition to standard medications, on allergic rhinitis. We also studied the side effects of consumption of virgin coconut oil. Methods: Fifty two subjects were equally divided into test and control groups. All subjects received a daily dose of 10mg of loratadine for 28 days. The test group was given 10ml of virgin coconut oil three times a day in addition to loratadine. The symptoms of allergic rhinitis were scored at the beginning and end of the study. Results:, the symptom score were divided into nasal and non-nasal symptom scores. Sneezing score showed a significant difference, however the score was more in control group than test group, indicating that improvement in symptom was more in control group. The rest of the nasal symptom and non-nasal symptom score showed no significant difference between test and control groups. Approximately 58% of the test subjects developed side effects from consumption of virgin coconut oil, mainly gastrointestinal side effects. Conclusion: In the present study, ingestion of virgin coconut oil does not improve the overall and individual symptoms of allergic rhinitis, furthermore it has side effects.
