Abstract

Background and Aim: Micro RNAs are a group of small non-coding RNAs which play an important role in multiple processes such as proliferation, differentiation, apoptosis, and cancer. Recent studies indicate that mir-210 is overexpressed into erythroid linage during the differentiation of hematopoietic precursor. The main goal of the present study is to investigate the influence of mir-210 on the pattern of expression in hemoglobin gamma chain.

Materials and Methods: First, K562 cell line was cultured in RPMI1640 media. Then, pre-miR-210 was transferred into K562 cell line by lipofectamin. Finally, the alterations in the pattern of gamma chain expression were analyzed in days 7 and 14 by RT-PCR and real time PCR technique.

Results: It was demonstrated that the overexpression of mir-210 in K562 cell line would lead to a 25-fold increase in the expression of gamma chain in comparison with the control group. Data analysis revealed that the change in the pattern of hemoglobin gamma chain expression was meaningful (p<0.002).

Conclusion: Based on these data, overexpression of mir-210 can lead to a significant increase in the production of gamma chain. Therefore, more studies in the field may reveal the fact that an increase in mir-210 can be a suitable goal in the improvement of sickle cell anemia and β-thalassemia.

Numerous factors affect the persistence of physicians in different regions, especially in deprived ones. This study aims to explain the experiences of physicians in relation to the challenges of working long in deprived areas.
Materials and Methods: The present research is a qualitative study that was conducted in 2020 in Tehran, Iran. To achieve information saturation, 16 physicians and specialists were chosen using purposive sampling method. Then, for data collection, semi-structured interviews were used. Moreover, data analysis was performed using Graneheim and Lundman contractual content analysis method, and data management was done with MAXQDA software version 12. Furthermore, Lincoln and Guba reliability criteria were applied to achieve data accuracy and reliability.
Results: Three female and 13 male physicians with a mean work experience of 45.4±7.8 years and an average work experience in deprived areas of 8±6.3 years participated in the study. Six participants were native to the region and the rest were non-native. Twelve participants in the study were the faculty members of the university. When the data were analyzed, 286 initial codes were extracted. The information was divided into four main categories and eleven subcategories. Welfare, motivation, justice and security were the main categories of this study.
Conclusion: Providing individual and social welfare for physicians, and fair treatment in financial payments and educational justice along with establishing security provide the necessary motivation for physicians to stay in a deprived area. Besides by combining several solutions at the same time, the presence of doctors in deprived areas can be guaranteed.
