The aim of this study was to evaluate bacterial contamination of keyboards of computers located in various wards of Vali-e Asr Teaching Hospital, Birjand, Iran. In this study, all computer keyboards in various wards of Vali-e Asr Hospital were sampled (n=24). Then, the samples were sent to Microbiology Research Laboratory at Birjand University of Medical Sciences and were cultured on Blood ager, Manitol Salt ager and Eosin Methylene Blue media. The isolated bacteria were identified based on their colonial morphology and biochemical characteristics. A total of 26 samples from 24 different computer keyboards of 16 different wards were obtained. Two keyboards of Infectious Diseases and Neurology wards were routinely disinfected at the end of every shift. All samples(100%) showed contamination to different bacteria. The keyboard of the computer located in Internal Medicine ward(women's division) was the most contaminated one. In total, 13 different bacterial spp. were isolated from keyboards of different computers. The species belonging to Enterobacteriaceae family(61.5%) were the most common contaminating bacteria followed by Bacillus spp(30.7%). Based on the results, all the sampled keyboards were contaminated by at least one bacterial spp. Therefore, it is necessary to pay more attention to the fact that computer keyboards in hospitals should regularly be disinfected.

Embryonic stem cells are identified with two unique characteristics. First, they can be maintained and expanded as pure populations of undifferentiated cells, a characteristic which is known as self renewal aspect of embryonic stem cells. Second, these cells can give rise to all body cell types. In the current study, we used a feeder-free condition to differentiate mouse embryonic stem cells into lymphoid lineage by IL-7 and FLT-3 ligand. Mouse embryonic stem cells cultured on mouse embryonic fibroblasts were separated from the feeder layer. Then, embryoid bodies were formed from mouse embryonic stem cells. Following that, differentiation was performed by FLT-3 ligand and IL-7. In order to demonstrate the differentiation into lymphoid lineages, the expression of CD25, CD19 and CD3 was assessed by RT-PCR technique on days 7 and 14. After 14 days of differentiation into lymphoid lineages by defined factors, RT-PCR results showed the expression of CD25 and CD19 markers. In all previous studies, mouse embryonic stem cells were differentiated into lymphoid lineage by OP9 stromal feeder cells. In this study, a feeder-free condition was used to differentiate mouse embryonic stem cells into lymphoid lineage. It is hoped that the present study can lead to new insights in cell therapy of lymphoid deficiency disorders.

Changes in political, economic, social, scientific and technological circumstances have a major impact on organizational performance. In such circumstances, the success of organizations depends on their ability to cope and adapt to changing environmental factors. This study investigated the relationship between organizational participation(team orientation, capability development and empowerment) and the organizational adaptability (change, customer orientation and organizational learning) in Imam Khomeini Hospital staff. This cross-sectional study was performed on 114 staffs of Imam Khomeini hospital, Tehran University of Medical Sciences who were selected by random sampling. Data were collected by Denison questionnaire (2006 version), which was confirmed validity and reliability. Data were analyzed with spss17 and statistical methods like the mean, standard deviation and correlation coefficients. The results showed that the rate of the organizational involvement and adaptability of the staffs was 53.44% and 52.37% respectively. The Pearson correlation analysis showed a positive correlation coefficient (p<0.01, r=0.743) between two variables of organizational involvement and adaptability. With increasing organizational involvement of the staffs increases their organizational adaptability

Medicine as a strategic commodity and basic needs of the most people in the country is important. According to the necessary recognition correct pattern of drug use, this study is conducted to measure the pattern of drug use among Ardabil city families. A cross -sectional descriptive study was conducted on 1000 randomly selected families from Ardabil city in 2010. Necessary information was gathered by interviewing one of the oldest people in the family. Collected data was analyzed using descriptive statistical methods in SPSS.16 software. 485(48.5%) of study people were female and rest of them were male. The mean age of samples was 41.6(SD=14.1). From all families 22% uses the drugs in home for curing diseases by self diagnosis. 10.9% of them do not respond to doctors non medical advice and prefer the doctor to prescribe drugs otherwise they refer to another doctor. Results showed that the drug use behavior between Ardabil city families was inappropriate and decreasing irrational use of drugs by providing necessary information to people regarding optimal use of medicine was necessary.

Patents are used as indicators to assess the growth of science and technology in a given country or area. They are examined to determine the research potentials of research centers, universities, and inventors. This study aims to map the past and current trends in patenting activities with a view to understanding better and tracking the changing nature of science and technology in Iran. The patenting activity in Iran was investigated based on USPTO, WIPO, and Esp@cenet for the period 1976-2011. The researchers analyzed the affiliation of inventors, and collected patents having at least one Iranian inventor. The collected data were analyzed using Microsoft Excel. results showed that between 1976 and 2011, 212 patents were registered by Iranian inventors in the above-mentioned three databases. The average number of Iranian patents registered per year increased significantly from 25 in 1976-1980 to 119 in 2006-2011. It should be noted that the highest number of registered patents (27%) were in" chemistry, metallurgy" area of International Patent Classification, followed by "human necessities"(18%), and "performing operations; transporting"(15%). Overall, the proportion of Iranian inventor's patents registered in databases is small. However, the figure shows a growth for the years under study. Iran's patents registered in databases have considerable subject concentration. Scientific areas are growing together, and there is more potential of research work and innovation in areas of "chemistry, metallurgy", "Electricity" and "human needs".

Identification of entrepreneurial opportunities in the field of nutrition counseling is a central issue in employing nutrition consultants and meeting the needs of patients with chronic diseases better. To this end, the present survey has been conducted in order to analyze the supply and demand trends of diabetes nutrition counseling as a basic step toward identifying the entrepreneurial opportunities for nutrition consultants in Tehran. To implement this descriptive-survey study, a questionnaire based on Likert scale was sent by email to 80 active professionals in the field of nutrition counseling services in Tehran, of whom 48 responded to its questions. Then, using SPSS11.5, the mean values of participant's responses were calculated and compared with one another. The findings obtained based on participant's responses revealed that the need for "nutritional counseling in the form of a treatment team" was mostly not met in different age, education and income groups of diabetic patients "Nutrition counseling in the form of a treatment team" can be considered as a suitable field for entrepreneurial activities.

Low weight at birth is one of the main health indexes in evaluating pregnancy period care, and recognizing its related factors is very important. The aim of this study was a comparison of pregnancy age, height, the distance between two pregnancies, gaining weight during pregnancy, economical condition, nutrition, general health of the mothers with low and normal birth weight. The research method was casual-comparative conducted as field-work. From all newborns born since (Jan 2008 to Nov 2009) 168 low birth weight babies with their mother and 157 newborns with normal weight from 20 maternity center at Guilan province were randomly selected. Mothers filled general health questionnaire with the reliability of 0.82. The data were analyzed using SPSS Software. There was a significant difference among mothers (case and control) in terms of pregnancy age, height, distance between two pregnancies, increasing weight during pregnancy, economical condition, nutrition condition and general health (mental), (p0.01). Various factors affected newborn's weight at birth. Therefore, decreasing the rate of low weight will be one of the main social health indexes requiring cooperation of counter- groups and different organizations such as the Ministry of Health and treatment, psychotherapy, counseling centers and radio/television.

The increase of food residuals specially in hospital can lead to a decrease in food intake and customer satisfaction and also increase the cost of remedy and hospitalization. The goal of this study was to determine the effect of food service training of food staff on the amount of food residuals to improve hospital catering. This was cross sectional study. The study population consisted of staff and patients in orthopedic, chemotherapy and surgery wards and their relatives (n=130). The tools of this study were satisfaction survey questionnaire and food residual observational checklist. Questionnaires were completed by the study population and observational checklist by the researchers. Data were analysed using SPSS Software. Significant difference were observed between the amount of food residual before and after personnel training (t=-5/36, p=0/001).The average amount of food remaining in the breakfast from 1/8 in pre-teaching was decreased to 0/7, at lunch from 2/09 to1/89 and in dinner time from 2/2 to 1/6. It seems that educational planning of personnel could increase their knowledge about their duties and weaknesses and improves quality performance which leads to customer satisfaction and hospital profitability.
