Method: This study was carried out based on a cross-sectional descriptive-analytical design. In this study, 25 laboratory science students participated and were assigned to two groups: jigsaw and traditional. In each session, the teacher assigned a topic for each member of the jigsaw groups, and the students were given a week to study the topic. Thereafter, in the educational method of jigsaw, each student explained the presented material to other members. In the traditional method, each session was conducted by a teacher. At the end, the lecture and jigsaw groups were tested with the same questions and the scores of the two groups were compared. Results: In the examination of the difference between the total score in the jigsaw and lecture groups using the non-parametric Mann-Whitney U test, the mean and median of the total scores in the jigsaw method were higher than the traditional method, and this difference was statistically significant at the 95% confidence level. Conclusion: Considering the many names of the parasitology course, hard learning, and students' complaints about the amount of content in this course, jigsaw can be a suitable method for teaching this course.","PeriodicalId":16423,"journal":{"name":"journal of north khorasan university of medical sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139350684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, animals were subjected to general anesthesia and SCI. After two weeks of recovery, two types of aerobic exercise programs were performed for four weeks. After performing the exercises, Basso Beattie Bresnahan (BBB) test and molecular tests were used to measure the expression of the NT4 gene from the hippocampus of the animals using the qRT-PCR method. Results: The BBB score in the exercise group compared to the injury group increased significantly. The expression of NT4 in the SCI group was significantly decreased compared to the control group. While, NT4 expression was increased in the SCI + exercise 1 group and in the SCI + exercise 2 group compared to the SCI group, this increased expression was not significantly different between the two groups of SCI + exercise.

In the present study, we aimed to investigate the protective effect of the hydromethanolic extract of ginger on cardiac parameters in male rats with renovascular hypertension. Method: A total of 54 rats were randomly divided into 6 groups as follows: control, hypertensive group, hypertensive group (hydromethanolic extract of ginger with a dose of 100 mg/kg), hypertensive group (hydromethanolic extract of ginger with a dose of 200 mg/kg), hypertensive group (hydromethanolic extract of ginger with a dose of 300 mg/kg), and surgical group receiving hydromethanolic extract of ginger with a dose of 200 mg/kg. Rats were gavaged for 42 days, once every day, using hydromethanol extract of ginger. Afterward, the heart rate was measured every 7 days. Ejection fraction (EF) and cardiac index were evaluated by SPSS-16 at a significance level of 0.05. Results: The results of the study showed that the hydroethanolic extract of ginger caused a significant decrease in heart rate in the group without induced blood pressure receiving ginger extract (dose of 200 mg/kg) and in the induced blood pressure group gavaged ginger at a dose of 200 mg/kg. It was also found that there was a significant difference between the average EF in the studied groups; however, the cardiac index had no significant difference in the studied groups.

The target population was pregnant women referring to Ali Ibn Abitaleb Hospital in Zahedan, Iran, in 2018 who were aged 20 to 38 years and were diagnosed with PTL. The control group included an equal number of women with the same age range but term labor. To investigate candida, trichomonas, bacterial vaginosis, and group B streptococcali, swab samples were taken from the vagina and rectum. Different laboratory methods were performed to isolate the above-mentioned microorganisms, including microscopy of wet mount smear, Gram stain, culture on Sabouraud agar, and 5% sheep blood agar. Moreover, four Amsel criteria were used to diagnose bacterial vaginosis. At last, the collected data were analyzed by SPSS-19 software with a p-value of 0.05. Results: A total of 300 patients were included in the study, and the mean age was not statistically significantly different between the two groups of PTL and term labor. No statistically significant difference was observed in the frequency of vaginal candidiasis (P=0.081), bacterial vaginosis (P=0.906), and trichomonas infection (P=0.904) between the two groups.
