Acute promyelocytic leukemia (APL) is a distinct type of leukemia which is caused due to a blockage in myeloid cells normal maturation. The most important therapeutic strategies include the use of ATRA and Arsenic trioxide. Although ATRA is generally well tolerated، some patients develop Retinoic acid syndrome. Some of the symptoms of this syndrome are directly or indirectly related to elevated WBC counts. This study aims to determine the effect of ATRA and BIBR1532 combination on WBC count as a factor leading to the formation of ATRA syndrome. To investigate the effect of BIBR1532 and ATRA combination، NB4 cells were cultured in the presence of 30μ M and 1 μM densities of the drugs. To study the effect of drugs on living cells count، proliferation activity، and metabolic activity of the cells، Trypan blue، Brdu and MTT tests were used، respectively. The results of Trypan blue، MTT and Brdu suggest that the combination of ATRA and BIBR1532 is more effective than ATRA alone on the reduction of viable cell count، metabolic activity and proliferation of leukemic cells in the first five days of treatment. The results suggest that the combination of ATRA and BIBR1532 is probably more effective in the treatment of APL patients. It seems that such improvement in results is more obvious especially among the patients who are at a higher risk of ATRA syndrome.

The hypothesis of supplier induced demand has attracted a lot of attention over the past three decades. Most studies in this field agree that healthcare providers have the ability to influence the demand for their products. The purpose of this study is to evaluate the role of institutions in the phenomenon of induced demand. This study has been done using experts'' experiences in Isfahan University of Medical Sciences. This is a qualitative study in which the semi-structured interview was used for data generation. The participants were those informed in this regard and considered as experts. For data saturation، purposive sampling was done. In this study، 17 people were interviewed، and criteria such as reliability and stability were considered. The anonymity of the interviewees was guaranteed. The data were transcribed and categorized، and then analyzed using thematic analysis. In the present study، thematic analysis was conducted and 30 sub-themes and 2 main themes were extracted. The two main themes were healthcare insurance organizations and other health organizations. Each of the themes had its own sub-themes. The findings help health policy-makers have a better picture regarding the role of various institutions in the phenomenon of induced demand.

Due to certain problems including being away from their families, entering a large and full-of-tension environment, and having economic problems caused by lack of sufficient income, students are likely to lose their mental health. This study is aimed to investigate college student's conditions and lifestyle at Tehran University of Medical Sciences (TUMS). In this cross-sectional study, 120 students from School of Allied Medicine were selected through simple sampling. Data collection tools included demographic questions and a lifestyle questionnaire. After collecting the questionnaires and coding the questions, the obtained data were analyzed through such statistical tests as t-test and ANOVA using SPSS software version 18. Student's scores on lifestyle test were in the intermediate range and far from a desired situation. A two-sample t-tests did not show a significant relationship between student's lifestyle and their gender and marital status (P>0.05). Moreover, ANOVA test didnt show a significant relationship between student's age and educational level on the one hand and their lifestyle factor on the other. The results of the study revealed that student's lifestyle scores were in the intermediate range and that the situation was far from good. Standard educational programs and interventions should be designed to change student's lifestyle. Nutritional and physical support systems and educational, cultural, and entertainment programs in the department of physical education can minimize the concerns and preoccupations of the studied population group.

Organization and utilization of non-book materials is an essential issue; therefore, this study aims to evaluate the organization of non-book materials in central libraries of selected universities of Tehran. The present survey has been conducted as a cross-sectional, descriptive study in 2012. The population consisted of central libraries of selected universities of Tehran. Data gathering instrument was a questionnaire divided into three sections. The validity of the questionnaire was checked by the professionals of the field and its reliability turned out to be 88% using Cronbach's alpha test. Data analysis was performed with SPSS and excel. The findings were presented using descriptive and analytic statistics. Most of non-book cataloged and indexed materials are theses and compact discs (CDs). Most of the libraries of this study use the Library of Congress Classification System for organizing their materials, and all of them (100%) apply Anglo-American rules for cataloging. Regarding the staff of libraries, 40 (95%) had academic degrees in library studies. As to their familiarity with OPEC, 4 libraries (80%) were familiar with Library of Congress (LC) and 3 (60%) were familiar with National Library of Iran. NOSA software was used in 4 (80%) libraries, and Windows operating system in all (100%). Based on the results of the present study, it can be concluded that the organization of non-book materials in these libraries is not as desired.

The importance of social networking sites (SNSs) is evident as a tool for research team working and for enabling researchers to share the results and experiences. The present study aims to identify the features of SRNs for facilitating research practices from the perspective of medical sciences researchers and to study the reasons why they use these networks. This was a qualitative research that employed content analysis approach. The participants were 10 medical researchers who were active in ResearchGATE, and were selected through purposeful sampling. The selection criterion was their scores in ResearchGATE (RG). RG scores are allotted based on publications, questions, answers and followers. The data were gathered using semi-structured interviews, and then were thematized and presented in the form of a list; the list of SRN's most important features for the field of medical sciences. The findings of data analysis revealed eight features for SRNs: presenting themselves and identifying other researchers, communicating and collaborating with other researchers, sharing information, finding information, managing resources and citations, keeping the researcher up to date, rating, and setting the network. Due to the importance and role of SRNs in communication and collaboration between researchers and their scientific production management, introduction of features identified in this study can enhance these SNS's efficiency and effectiveness. Information science professionals can use the findings of this research to design educational workshops on "Familiarity with the features of SNSs for researchers" as a new information service in libraries.

In order to develop teaching competencies and prepare PhD candidates for future roles as faculty members of medical schools, the present study conducted to determine PhD candidates` educational needs and their skills concerning teaching competencies.

Personal Information Management (PIM) is a novel approach comprising three interactive parts of information resources, dimensions, and tools. The main aim of this study was to determine the degree of Tehran University of Medical Sciences (TUMS) management and information science students’ familiarity with PIM process. The present work is a qualitative-applied study and the population includes 145 TUMS management and medical information students in 2012. The subjects were randomly selected and the data were finally obtained from 73 persons through semi-structured interviews. The data collection tool was a questionnaire with 10 open-ended questions classified based on the conceptual framework of interviews. The questions were about how to acquire, organize, maintain, and retrieve information. To analyse the interviews, the qualititative data analysis software Nvivo 8 was employed. According to the obtained results, 51% (37 persons) of interviewed persons have applied methods and tools in order to organize and maintain information and have had exclusive methods to retrieve information. The most frequent worries were the information storage 49% (35 persons) and acquiring information 29% (21 persons). It is noteworthy to say that the PIM approach is not very popular among university students, and many of them acquire, maintain, and organize their personal information inappropriately in spite of their need for the method. Therefore, educating the students and promoting their performance can result in the improvement of main PIM-related problems.
