Educating pediatricians regarding oral health and early childhood caries can have a great effect on improving their knowledge, attitude & practice. The aim of this study was to determine the knowledge, attitude & practice of pediatricians regarding oral health and early childhood caries in city of Isfahan.

In this descriptive-analytical study that is cross sectional, 80 pediatricians were selected randomly and a questionnaire that reliability and validity of it had been approved, was distributed between participants. Questions separately in terms of knowledge, attitude and practice regarding oral health and early childhood caries were designed. Finally, after collecting the questionnaires, Statistical analysis was performed using descriptive analysis (mean and standard deviation), Pearson correlation and Independent T-Testwith the 0.05 level of significance.

The mean knowledge score was 58.4, the mean attitude score was 79.2 and the mean practice score was 55.5 (from 100). There was a direct significant relationship between pediatricians’ knowledge score with attitude (p value < 0.001) and practice (p value < 0.001), in addition there was a direct significant relationship (p value < 0.001) between pediatricians’ attitude score and practice score too. There was no significant relationship between knowledge with age (p value = 0.12) but there was a significant relationship between attitude (p value = 0.01) and practice (p value < 0.001) with age. There was also a significant relationship between with knowledge (p value = 0.03), attitude (p value = 0.01) & practice (p value < 0.001).

The mean of pediatricians’ knowledge and practice score were average. Since there was a significant relationship between knowledge and practice score, so increase the pediatricians’ level of knowledge and improvement the attitude and practice of them in this context is important and developed training programs are necessary for them.

Student satisfaction as the main pillars of the university has increased efficiency and should be at the top of educational planning. Student satisfaction indicates that all educational areas are effective scientifically and practically and refers to a set of consistent and incompatible feelings towards the field of study. The purpose of this study was to evaluate student's satisfaction with their Field of Study in 2019-2020 in Saveh University of Medical Sciences.

This is a descriptive and analytical study performed among students of different fields of medical sciences in Saveh University of Medical Sciences. Students are selected through stratified random sampling from all fields of study and entrance examinations. Data are collected through a research made questionnaire that was designed by some researchers and confirmed by its validity and reliability. Descriptive statistics (frequency, mean, mode, etc.) and inferential statistics (Spearman correlation coefficient and independent t-test) were used for data analysis.

The mean score of satisfaction with the field of study was 57.1 and was average. There was a positive relationship between students' academic satisfaction and their degree (P = 0.012).

Considering the results, attention was given to the advisor support at the universities, the locations and the numbers of students in the academic field and in the recruitment process. It is important for students to be mentored and for families to engage and interact with the educational system in universities.

Artemisia annua is particularly important for the production of artemisinin, a bioproduct which can be used to combat the causal agent of malaria, treat some kind of cancers and in other activities. The low artemisinin content in the plant has caused this compound to be among the more expensive medicines. Several attempts have been made to increase artemisinin production, for example by using different elicitors, but none of the approaches has been cost effective. In this study, the expression levels of two important genes in the artemisinin biosynthetic pathway, SQS and DBR2 and artemisinin content were investigated in Artemisia cell suspension cultures. SQS and DBR2 genes have essential roles in the regulation of artemisinin pathway. For this purpose, nano-cobalt particles in concentrations of 0.25, 2.5 and 5 mg/L were used for cell culture treatment and samples were collected after 8, 24, 48 and 72 h. The highest artemisinin content was observed 24 h after 5 mg/L nanocobalt treatment. In this case, artemisinin production was 2.25 times (113.35 mg/g d.wt) higher than that of the control. Our results showed a negative and significant correlation between SQS and DBR2 gene expression and artemisinin content at different levels of nano cobalt treatments. Results also showed an increase in nano cobalt concentration after 72 hour and an increase in nano chitosan after 4h hour caused a significant decrease in the expression of SQS and DBR2 genes. In conclusion, it appears that the content of artemisinin was increased by high concentrations of the nano cobalt particles because of a decrease in the expression of SQS and DBR2 genes.

Dashtak is one of the villages of Dorodzan area in Marvdasht city of Fars Province. The Dashtak dialect is one of the dialects of Southeast of Iran. This paper descriptively analyse the data in the form of case study. In Dashtak dialect, in some verbs, the indicator comes at the beginning of the verb instead of at the end of the verb. The indicators in various verbs have phonetic differences. In future verb tense, in contrast to Persian language in which the first part of the verb is pronounced the Dashtaki dialect pronounced two parts of the future verb
