Abstract

Background: According to the important of SALL4 gene during the development of embryonic neurvous system, our aim in this study was to analyze and quantify mRNA expression of SALL4 in Prosencephalon during different stages of chicken embryogenesis.

Materials and Methods: In this experimental study, incubated Ross fertilized eggs were applied in 37°C-37.5°C in 60-65% humidified atmosphere after beginning of embryogenesis. Prosencephalon part of the brain tissue was collected from the eggs, daily. Total RNA extraction and cDNA synthesis was performed from resected tissues. The synthesized cDNA was used as template for quantitatively analysis of SALL4 mRNA expression by real-time PCR.

Results: The Results indicate that the level of SALL4 gene expression is significantly variable during embryogenesis. However it doesn’t show variation during the early days. The maximum copy number of SALL4 mRNA was quantified on 15 th day of chicken development.

Conclusion: SALL4 mRNA expression is high when the Prosencephalon is under development, using of HAMBURGER–HAMILTON chart, there is relation between increasing SALL4 expression and developing limbs and anterior brain.

Abstract
Introduction: One of the problems during adolescence is the existence of conflict with parents, which creates object relationships and feelings of shame and guilt in them. This research was conducted to determine the effectiveness of treatment based on the mentalization of object relations and feelings of shame and guilt in conflicting mother-child relationships.
Methods: This research method was semi-experimental and pre-test-post-test with a control group. The statistical population of this research included all mothers and adolescents with conflicting relationships who were referred to counseling centers in Shiraz in 2022. By using the available sampling method, 30 people from the mentioned community were selected as a sample and were randomly divided into two experimental (15 people) and control (15 people) groups. Asadi et al.'s parent-child conflict questionnaires (2010), Bell's object relations (1995), and Cohen et al.'s (2011) feelings of shame and guilt were used to collect information. The experimental group underwent executive function training for 13 sessions twice a week for 60 minutes, and the control group did not receive any training. The research data was analyzed using correlation.
Results: The mean ± standard deviation of the experimental group in the post-test in the variable of object relations from 1.5 ± 1.37 to 28.6 ± 4.3 and in the variable of shame and guilt from 5 ± 1.60 to 5.60 ± 3. 51.2 ± 9.1 decreased. The results showed that in the post-test stage, the mean scores of object relations and feelings of shame and guilt in the experimental group decreased significantly compared to the control group (P < 0.01).
Conclusions: Treatment based on mentalization was effective in improving object relationships and reducing feelings of shame and guilt. Therefore, this treatment can be suggested to reduce the conflict between adolescents and mothers.
