Volume 2, Issue 4 (29 2009)
Abstract

Background and Aim : Lactoferrin is one of the milk components with the main role in iron absorption and transfer. As a result of this action the pathogens that need iron for their life cannot grow, so the infection will be controled, indirectly. Moreover, because the lactoferrin production is stopped in the women with breast cancer, evaluation of this protein in milk may be the first step in detection of breast cancer tumors, and making decision about the appropriate treatment methods. Therefore, with due attention to the important role of lactoferrin in health and disease, determination of its normal dose in milk is very essential for the differences that may occur comparing with the normal situation. Also since the normal amount of lactoferrin in the milk of Iranian women was not evaluated in this study the amount of protein in more than 100 sample was measured.

Materias and Methods: The lactoferrin amount was measured by SRID method in 104 human milk samples of mothers that were referred to two public health centers in Tehran for vaccination of their children, and also in women that were hospitalized after childbirth in 2 health centers of Qom city. The data such as age, time of childbirth, etc were obtained by asking them and filling pre-designed questionnaire. All laboratory experiments were conducted in the Immunology unit of pathobiology department of School of Public Health, Tehran University of Medical Sciences.

Results: The mean concentration of lactoferrin was 4.39 g/L, in the early milk (6-10 days after childbirth) was 3.79 g/L and in the mature milk (11-60 days after childbirth) measured as 2.45 g/L.

Discussion and Conclusion: The mean concentration of Lactoferrin in milk (g/L) has a significant difference with the day after childbirth (P<0.05) and was highest in Colostrums and then in primary milk. After that this amount is reduced extremely. This indicates the important role of lactoferrin in the primary days of infants, because of the protective role that it has against infections. Also the results of this study showed no significant correlation between human milk and factors such as age and childbirth time.

Volume 15, Issue 4 (oct & Nov 2021)
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.

Volume 16, Issue 3 (Aug 2022)
Abstract
Background and Aim: Medical resources are directly related to health of society and the book as one of the main sources has great importance. This study has been conducted to investigate pathology of medical sciences books publishing status and also identification of content, cultural and technical production challenges of these books in Iran from the viewpoint of publishers.
Materials and Methods: The present study in terms of purpose, approach, and method is applicable, qualitative and phenomenology. The research tool has been semi - structured interview and community were publishers of medical sciences books in two sections academic (Five) and private (eight) publishers. The interviews continued until the data saturation stage (13 interviews). First, open and axial coding was performed, which finally extracted 402 codes and then was categorized into 74 categories, which were analyzed using qualitative content analysis.
Results: The field of content production faced the most important challenges (53%), in which policy making absence (24 repetitions, 16%), no domestic high percentage of medical publication (23 repetitions, 16%), and the lack of expertise in medical publishers (11 repetitions, 7%), were declared by publishers. The problems of cultural production were in the second place with 39% and respectively include specialized and costly editing of the book, the lack of professional referees and the lack of structured review rules with 22 repetitions equivalent to 46%, 8 repetitions equivalent to 17% and 6 repetitions equivalent to 13%. The challenges of the technical production sector are reflected with a number equal to 8% of the total problems, which include the problems of raw materials printing and publishing (11 repetitions, 48%), lack of printing and publishing technology (5 repetitions, 23%) and the lack of technical expertise staff (3 repetitions, 13 percent).
Conclusion: According to the findings of this study and the revealed funds of damages in the medical publishing industry, it can be concluded that many publishing challenges in Iran are rooted in general policies, rules and culture. Therefore, more serious attention to the professional field of medical publishing from the government and unbiased policy making in order to divert the concerns of publishers can solve many obstacles and difficulties.

Abstract
Background and Aim: One of the most important challenges in the field of research information management is the use of reliable and qualified software to manage research resources in health domain. This study aimed to develop a validation tools for research information management systems in Iran to utilize by universities in the process of using existing research information management systems.
Materials and Methods: This was a descriptive study conducted in two stages. In the first stage, a validation tool for research information management systems (Pajoohan, Pajooheshyar, Jiro, Yektaweb, Kuiper) was designed, and in the next stage, in order to ensure the validity of the produced tool, a self-assessment survey was conducted by users of research information management systems in medical sciences universities. Therefore, this tool was completed by 104 researchers from all over the country. The collected data were analyzed by Excel and SPSS software.
Results: The developed validation tool of research information management systems included four components and 82 indicators: software design and architecture (17 indicators), usability and user environment (16 indicators), professional use (36 indicators) and management (13 indicators). Based on the self-declared results of the users, this tool has 57 mandatory features, 26 preferred and 4 optional features. The results of the validation of research information management systems based on this tool showed that the highest rank in the component of architecture, professional use and software management was related to the Kuiper system, and in the component of usability and user environment was related to the Pajoohan system. In the self-declaration done by the users ,12 cases of Jiro system ,11 cases of Kuiper system ,11 cases of Pajoohan system ,7 cases of Pajooheshyar, and 5 cases of Yektaweb system have received confirmation above 75%.
Conclusions: The validation tool which developed by this study can be used in the evaluation of current research information management systems and the selection of new systems for use in the research field. In addition, it can be used to improve current systems and purchase new systems by academic universities and research centers.
