Abstract
Background and Aim: Using Hirsch index as an important tool to describe the scientific outputs of researchers has caused some authors to increase their self-imposed parameters, increase, citing themselves. Therefore it is necessary to consider the effect of self-citation on Hirsch index for every author to have better measuring on the quality of researchers scientific production.
Materials and Methods: This research is descriptive method of citation analysis in general and specifically self-citation analysis. The study, are Iranian prolific authors in the field of medicine that have at least 30 documents indexed in Web of Science database between 2004 to 2006. Citations following up was studied till December 2010 Results was analysis using Excel software version 2007.
Results: The average self-citation observed between prolific authors in medical field was 25/89 percent. Hirsch index for 30/77 percent of authors had changed considerably. The authors rating scheme based on Hirsch index was done after removing self - citation so that 38/46 percent of authors decreased to lower level.
Conclusion: Considering that 10 to 30 percent of self-citation can be normal and justified, the status of self-citatin of Iranian prolific authors in medical field is desirable. Also, lower rates of self - citation of these authors doesnot affect Hirsch index.

Abstract
Background and Aim: These days with the improvements in science and technology the number of individuals who suffer from genetic disorders should be drastically less. A crucial method for preventing these disorders, in the first place, is by genetic counseling. Educating the public in regards to how they can avoid producing affected children.
Materials and Methods: In this retrospective cross- sectional study, all the files of the couples attending Genetics Clinic of the Imam Khomeini Hospital Complex, during 1995 to 2004 were studied. The data were collected using a reliable questionnaire and SPSS software was applied for data analysis.
Results: The most important variable in this study was the relationship between the couples. The most frequent among the consanguineous marriages was the cross first cousins (45.3%), and the least frequency belonged to non-related marriages (6.4%). The most frequent genetic diseases belonged to children who their parents were parallel first cousins (84.8%).
Conclusions: Due to the importance of genetic counseling in relation to reducing the frequency of the genetic disorders in society, educating the general public about compulsory genetic counseling before marriage, is the cheapest and the most effective approach in limiting the number of patients
with genetic abnormalities.

Abstract
Background and Aim: Although vancomycine is used for the treatment of methicillin resistant Staphylococci, but vancomycine alone might not be effective for the treatment of methicillin resistant Staphylococci in compromised host. In the same time antimicrobial activity of cefepim on gram positive bacteria especially Staphylococci is well known. In this study the synergism effect of cefepim and vavcomycin on positive and negative coagulase Staphylococci in vitro condition was investigated.
Materials and Methods: In total, 100 clinical samples of coagulase positive and negative Staphylococci were isolated from urine and blood samples from patients in Imam Khomeini Hospital during one year and identified .The modified Bauer-Kirby were used for the antibiotic susceptibility and macrodilution method for the MIC according to NCCLS procedure.
Results: The results showed that after adding vancomycin to cefepime in concentration from 0.05+ 0.5 , to 0.8+8 , growth reduction reached from 3.5% to 100%.The synergism effect of the two mentioned antibiotics on coagulase negative Staphylococci resistant to methicillin were shown that from concentration of 0.05+ 0.5 to 0.8+8 , a reduction in growth from 4.5% to 100% was observed.
Conclusion: The results of this study showed that vancomycin and cefepime has synergic effect on Staphylococci

Abstract
Background and Aim: ESR1 gene polymorphism has been found to be associated with breast cancer and clinical features of the disease in Caucasians. Genomic data for ESR1 in either population is therefore of value in the clinical setting for that ethnic group. In this study association of polymorphism in ESR1 gene with breast cancer risk was investigated.
Materials and Methods: A case-control study was conducted to establish a database of ESR1 polymorphisms in Iranian population. The ESR1 gene was scanned in Iranian patients newly diagnosed with invasive breast tumors, (150 patients) and in healthy individuals (147) (healthy control individuals). PCR single-strand conformation polymorphism technology and direct sequencing was performed.
Results: The frequency of heterozygote genotype in exon 8 (ACG → ACA / ) was significantly higher in breast cancer patients (48.0%) than in control individuals (1.4%). We found that mutant allele (ACA) was significantly more common in breast cancer patients with age at menarche
Conclusion: Our data suggest that ESR1 polymorphisms are correlated with various aspects of breast cancer in Iranian ESR1 genotype, as determined during pre-surgical evaluation, might represent a surrogate marker to increase predicting breast cancer in Iranian population.

Abstract
Background and Aim: Considering the effect of organizational climate on work motivation, not using the librarians who have a satisfactory feeling about their job can cause irreversible damages to the library. Therefore, the aim of this study is to determine the effect of organizational climate of college and hospital libraries on the burnout of librarians working there.
Materials and Methods: This is an applied research and a descriptive-analytical survey. One hundred seventy-seven librarians from faculties and hospital libraries affiliated to Tehran, Iran and Shahid Beheshti Universities of Medical Sciences were surveyed by census method in 2019. Data collection instruments were Halpin and Croft's organizational climate and Maslach and Jackson job burnout questionnaires. The validity was confirmed by 3 experts and the reliability by Cronbach's alpha coefficient. For data analysis, SPSS software, and descriptive and analytical statistics were used.
Results: The findings showed that the mean of organizational climate was at a desirable level (3.4) and the average of job burnout was 1.7; therefore, the job burnout status of librarians is desirable because it is a negative variable. Also, the components of organizational climate predict 41% of job burnout variable. Among demographic characteristics, job burnout variable varies only in terms of field of study, and organizational climate only in terms of the type of library.
Conclusion: In general, the organizational climate status and job burnout status of the studied libraries are desirable; also, organizational climate components affect job burnout.

Abstract
Background and Aim: Health systems have played an important role in improving and increasing life expectancy. However, there is a large gap between health systems’ potential and their current performance, most of which relate to governance issues. The purpose of this study is to provide a model for improving the governance of the country's health system.
Materials and Methods: The present study is applied-developmental in terms of purpose. After reviewing the theoretical foundations and previous research, the governance strategies of the health system were identified. Then, using Fuzzy Delphi Method (FDM) and surveying 13 academic and executive experts who were purposefully selected, the research model was designed. Finally, in order to validate the model, 169 managers and specialists of health system departments in Tehran were interviewed with a questionnaire, and the data were analyzed using structural equation modeling (SEM) and SmartPLS software. At this stage, the sampling method was available and the sample size was calculated by Cochran's method.
Results: According to the research findings, in order to promote health governance, 10 main strategies and 58 sub-strategies should be considered. Identified strategies include strategic orientation, optimal financial resource management, stakeholder partnership development, knowledge resource development, administrative health promotion, technical knowledge development, value and ethical orientation, executive and operational platform development, Service delivery capacity management and Balanced and integrated stewardship. Also, the coefficient of determination for the outcome variable is 0.549 and the intensity of the effect of intervening/ facilitating and contextual factors on governance strategies is equal to 0.610 and 0.533, respectively.
Conclusion: The results showed that the governance of the health system is a multifaceted and complex phenomenon and in order to improve it, a set of strategies must be implemented. In addition, it is suggested that according to the issues and threats facing the health system, a roadmap and a long-term plan should be developed in order to move towards the governance model proposed in the present study.

Abstract
Background and Aim: Transgenic species are the ones whose genomes are genetically modified. The transgenic field is one of the areas that has a high importance and position in the world. Therefore, the aim of the present research is to draw and analyze the co-authorship network of researchers in transgenic subject area.
Materials and Methods: The type of this research is descriptive and was carried out using scientometric techniques such as co-authorship network and social network analysis indices. In this study, 23,456 articles by transgenic researchers indexed in the Web of Science database during the period 2010-2019 were retrieved. VOSviewer and UCINET software were used to draw the co-authorship map and analyze the network indicators.
Results: The scientific cooperation network of transgenic researchers was studied and analyzed using macro and micro indicators of the social network. The status of macro indicators was not appropriate and the network was poorly cohesive. So that, the network density was 0.027, the clustering coefficient was 0.834, the diameter was 15 and the average distance was 4.155. In terms of micro-indicators, the status of researchers in the network was determined in such a way that David Ayares had the most cooperation with other members and also Nam-Hai Chua played the most important role in communicating with people from different clusters of the network, finally, Yan Zhang had the shortest distance with other members of the network.
Conclusion: Based on the findings, it can be concluded that the co-authorship network of transgenic researchers has low cohesion and information is transmitted among members at a low speed. With respect to this, status of different researchers in this study was determined, the results of this study can be used to guide future collaborations, and encourage universities and scientific institutes to develop their interactions with each other and further strengthen collaborations. It should also be noted that according to the findings of the study in this field, Iranian researchers were not identified as key individuals in this network, which requires research on the status and position of Iranian researchers in the field of transgenics.
