Introduction: Migraine as one of the most common types of headaches with high prevalence has significant impact on the lives of patients. This study estimated migraine prevalence and clinical characteristics of migraine patients in Hamadan.Methods: In this crossed- sectional study, all patients who referred to the neurology department of Sina Hospital from 2010.03. 21 to 2011.03.20 and confirmed by neurology specialists as migraine patients, were studied. Demographic data (age, sex, occupation), the scale migraine disability and clinical characteristics data were collected. The obtained information was analyzed by using SPSS v 16.0 software descriptive statistics.Results: During the study, 128 (12.8%) of the migraine patients referred to the neurology clinic. Females constituted 68.7% of the patients. The average frequency of migraine attacks was 9.1 in a year. Pulse headache in 91 patients (85.1%) and one-sided headache in 79 patients (61.7%) were seen. Nausea and anorexia, respectively, the first (67.1%) and second (43.7%) had symptoms associated with migraine. Based on the obtained information from the mean MIDAS 53 (41.4%) of the patients with the average score of 23 showed severe performance degradation.Conclusion: Findings related to the severity of headache after that loss of work to reflect the importance of the social impact of migraine and the need for making strategies for migraine prevention and treatment are very important. In other words, more attention should be paid to initial prevention, diagnosis and treatment.

Introduction: Coagulation factor X is an important protein in the blood coagulation pathway. It contains significant structural features that affect its function. The purpose of this study was to investigate the structural-functional features of activated form of Factor X in the presence of calcium ions. Factor X consists of 4 domains. Gamma-carboxyl glutamic acid (GLA) domain contains negatively charged and hydrophobic amino acids. These two amino acid groups with contrasting characteristics are responsible for binding to calcium ions and the membrane respectively, so it provides appropriate folding of Factor X in the presence of calcium ions. Epidermal growth factor-like domain (Epidermal growth Factor) which includes EGF1 and EGF2 is the edge between GLA and serine protease domain (SP) and it is involved in binding calcium.Methods: Gathering and collecting of data has been done from molecular research in this area. It includes descriptions of three-dimensional structural characteristics of the Factor X.Conclusion: The catalytic role of Factor X is performed by SP domain; which made the heavy chain of factor X. Amino acids of SP domain play role in binding factor X to different activator and inhibitor.

Introduction: The aim of the current study was to investigate, evaluate and compare Hamadan University of Medical Sciences’ libraries with Iran standards of academic libraries.Methods: The research communities were libraries of Hamadan University of Medical Sciences’ libraries included Central LIBRARY, schools and hospitals. This applied study was conducted in 2010-11 academic year and was a survey method. The data were collected using a standard questionnaire and analyzed. The obtained results were compared with the standards of the university libraries of Iran.Results: The results of this study indicated that none of the libraries corresponded to the standards. At the time of doing this study, most of the libraries had no implementing regulations and statutes legal, managers lacking of library education, and were not suitable software for computerized work library. Libraries of this collection had 8% of required resources, 79% of manpower, 15.04 of space, 16.51 of publications, the lack of adequate funding and facilities.Conclusion: According to the results, none of the libraries fully complies with standards.

Introduction: Despite the decline of infant mortality in recent years, this problem is still in health care system in society. Identification of factors affecting infant mortality enables the health systems to design effective interventions. This study aimed to identify factors that contribute to infant mortality in high-risk pregnancies.Methods: This study was a cross-sectional study in which neonatal deaths in 2011, were investigated in Tuyserkan City. Data were collected primarily through city family health unit and then the checklist of care records and medical records were collected from newborns died. In this study, the influence of risk factors for pregnancy and newborn mortality by categories of mothers in both groups were free of risk factors and risk factors. The data were analyzed using Stata 11.Results: In this study, the higher risk of gestational were for ages greater than 35 years and more than four times (16.1%). Among the variables examined, only the method of delivery and prematurity in infants without risk factors was different between the two groups of high-risk mothers. Significantly greater risk of cesarean delivery in women without risk factors was maternal (p=0.03). The most important underlying cause of death was premature infants (60.09%).Conclusion: Special attention is required during preconception, pregnancy and postpartum care for mothers at risk or high risk, especially since it is mandatory according to the country’s health system. Moreover, providing quality health education and counseling to couples counseling and genetic testing can be effective in reducing infant mortality.

Introduction: since the most important asset of any organization is its human resource and organizational Performance goals of any organization depends on the people who work in the organization; the role of job satisfaction is an important factor in motivation is obvious. Hence, this study carrying with the aim of assesses satisfactory health care workers of Hamadan city.Methods: This cross-sectional study was conducted as a census 278 staff at health centers in Hamadan. Also to measure job satisfaction use questionnaire Smith (JDI), which have six areas. The data were analyzed using SPSS software.Results: The results showed the mean overall satisfaction score of 2.57±0.5 (from 5). The effect of gender on job satisfaction determined No significant association was found with gender. The results showed that the level of education was significant association with both subscales promotion & direct responsible, in this way higher education level, have direct associate with opportunities & direct responsible satisfaction.Conclusion: The results showed that appropriate supervision in an organization would create an enjoyable working atmosphere. Moreover, by trying to resolve the economic problems of the staff, it would have beneficial effects on increasing job satisfaction among the employees.

Introduction: As seasonal turbidity is one of the major challenges in drinking water supply; consequently, take an appropriate method to provide standards range is necessary. This study aimed to determine the effect of Snail shell as a coagulant aid in the removal of turbidity in aqueous environments using electrocoagulation process through aluminum electrodes.Methods: This experimental study was investigated at the laboratory scale. The used reactor had a volume of 1 liter whit four aluminum electrodes as a cathode and anode in the form of a direct current power supply. Effects of pH (9-6), initial concentration of turbidity (200 Nephlometry Turbidity Unit to 800 Nephlometry Turbidity Unit), reaction time (30 -10 min), the concentration of Snail Shell (0.5-4.5 mg/L) and the potential difference (10-40 V) were examined.Results: The findings indicated that the best performance for turbidity removal obtained at pH 8, reaction time 30 min, potential difference of 40 V, SS 2 mg/L dose of coagulant aid concentration and turbidity 200 Nephlometry Turbidity Unit.Conclusion: The results suggest that Electrocoagulation process using aluminum electrodes have good performance for removal of high concentration of turbidity and snail shell coagulant aid is a good option to improve the performance of the electrocoagulation process.

Introduction: Choosing the effective disinfectants and using the standard methods of sterilization in hospitals could be useful in decreasing nosocomial infections. The aims of this study were the evaluation of efficacy of new disinfectants including Sanosil, Alprocide, Bibfort, Javel- dose compared with Micro10 and Deconex on isolated organisms from dentistry units.Methods: This was an in vitro study and the sampling was randomly performed from different parts of dentistry wards and dentistry units. Three units were selected from each ward before disinfection. Overall 120 samples were taken from the selected dentistry units (20 samples from each ward at two steps). The effect of the disinfectants on isolated bacteria was investigated by disk diffusion method (Kirby-Bauer). Data was collected through a questionnaire and analyzed using Paired samples T-test and SPSS software.Results: Out of 120 cultured samples, 98 positive cultures (81.6%) were obtained that 254 strains and 14 bacteria species were isolated that 72.1% of them were gram-positive and 27.9% were also gram-negative bacteria. The most effective disinfectants on pathogenic strains were Deconex with 18.62 mm mean diameters of inhibition zone and Alprocide with 17.22 mm mean diameters of inhibition zone.Conclusion: The results showed that of 6 tested different disinfectants, Deconex and Alprocide were very effective, Sanosil and Javel-dose were relatively good, Bibfort had mild efficacy. however, Micro 10 was relatively weak.
