In biology considering identification of sequencing of macromolecules, different techniques such as Electrophoresis agarose gel is used after separation from different cells. Ethidium Bromide is one the materials for coloring these gels throughout the world due to it’s low price comparing to other materials. In last years, extensive use of his material in biology and medicine labs and due to it’s solubility and persistency in water, natural ecosystems contamination has became an important issue. Entering the human body can lead to enhanced cancer incidence by disturbance of blood circulatory system, activation of different tissues and modulation of translation and transcription of DNA process. Several physical and chemical methods has been suggested for neutralization of Ethidium Bromide inducing BDD electrode, TiO2, activated carbon adsorption and etc. which nearly all of these methods have not been used extensively by investigators due to high price and complex procedures. Fenton’s oxidation is one of materials for neutralization of unfavorable chemical compounds and this material has not been studied for neutralization of Ethidium Bromide. Due to high utilization of Ethidium Bromide in labs, the aim of this study was to investigate the potential effect of different levels of two chemical materials Feso4 and H2O2 for neutralization of Ethidium Bromide. 6 treatments including different levels of Feso4 and H2O2 were investigated. The treatment containing 200 Mg / liter of Feso4 along with 300 Mg / liter H2O2 had the most potential for neutralization of Ethidium Bromide comparing to other treatments.

The outbreak of the coronavirus has caused worldwide panic and psychological damages. The psychological problems caused by this prevalence have led to the formation of numerous protocols for psychological assistance to individuals. The purpose of this paper is to investigate the effect of spiritual and non-spiritual interventions in stress management due to the prevalence of coronavirus in Tehran clients referring to psychological clinics. The structured questionnaire was provided to three groups via the Internet to assess the effects of stress caused by corona prevalence, and 60 of the 120 completed questionnaires were analyzed until the results were analyzed. The findings showed that those who underwent psychological therapy were better able to control their stress than those who did not. Comparisons between spiritual therapy and other psychological therapies also show that God-Oriented Spiritual Therapy (GOST) has been able to help people in many different ways, and in many ways has been significantly more effective than non-spiritual therapies. These findings formed the basis of a protocol for coping with stress caused by coronavirus. therefore, based on responses of GOST group, short-term program was developed based on the God-oriented spiritually multi-dimensional therapy protocol to control the stress of the affected people.

The objective of the current research was to determine the relationship between parenting styles and pro-social behaviours (particularly respecting to rules) among pre-school children in Tehran's pre-school centres. 394 children whom were enrolled in this study and their mothers, were randomly selected through a multi-stage cluster sampling. Pro-social behaviours of children was assessed by means of teacher's rating checklist of pro-social behaviours and parenting styles was assessed by means of parenting style questionnaire. Findings showed that there is a positive and significant relationship between authorative parenting style and pro-social behaviours. According to the findings of this study, there is a significant relationship between parenting styles and pro-social behaviours of children, especially their respect to rules.

The purpose of this study was to assess the reliability and validity of the Depression-Happiness Scale (H-PS) in staff of Isfahan justice.Methods and Material: 200 subjects (134 male, 66 female) with a mean age of 33/7(ranged from 21to56) and standard deviation 10/6 were chosen among 900 staff of Isfahan’s court. Their literacy level ranged from diploma to MS. All subjects completed the Depression-Happiness Scale (D-HS), Beck Depression Inventory (BDI) and Oxford Happiness Inventory (OHI) in one session. The study of internal consistency of D-HS showed that all items have high correlation with total scores, the Cronbach alpha was0/93 and test-retest reliability after two months was0/72. D-HS was highly correlated with OHI and BDI. The factor analysis revealed 5 factors with an eigenvalue greater than 1, which could explain 57/1% of the total variance. But because first factor with an eigenvalue10/72 accounted for most (42/91%) of the variance, a one-factor model was specified. Depression-Happiness Scale is a reliable and valid test for measuring happiness in Iranian population.

The Value Systems and self-Esteem are two factors of mental and social health. This research aimed to investigate the relationship between parents value and interests and Self-Esteem of students. 212 male and female adolescents were tested by Coopersmit self-Esteem Inventory (SEI) and 212 parents of the same students were tested based on Alport, Venon and Lindzey. Analysis of data (Pearson’s correlation, Regression analysis) demonstrates a significant correlation between some of the dimentions of parents value interests (Just Mothers) and Student’s self-Esteem. Social intrest values of mothers were negatively correlated with Studen’s self-Esteem. Effects of value interests of parent on student's Self-Esteem were different.
