"n"nMethods: The patients who were candidates for hysterectomy with benign disease, with no contraindication for laparoscopic surgery entered the study in Arash Hospital, from March 2007 to April 2009. By simple randomization 45 patients (25 for TLH and 20 for SLH) were selected. Demographic Details and intra and post operative complications, were recorded by the staff and were compared between two groups."n"nResults: The average time for TLH operations look significantly longer than SLH operation (148.6±29.7 minutes; 128.5±25.64 minutes, p=0.03). Although, the hemoglobin (gr/dl) drop in TLH was significantly higher than SLH (1.54 Versus 0.9, p<0.05) Blood transfusion were common in SLH (1 case Versus 3 Cases). The total length of hospital stay, was significantly shorter after SLH than TLH (3.6±1.47 day and 2.85±0.59, p=0.04). The drug requirements to control pain during hospitalization after both surgeries with analgesic injection were not significantly different, but with suppositories analgesic in SLH more than TLH. The time of return to normal activity was reported (p<0.0001) significantly shorter after SLH than TLH (13.12±18.1 and 5.04±1.79, p=0.0001). Sexual function had no significant difference between two groups but dysparunia in SLH was significantly lower than TLH (p=0.02). Cyclic bleeding and cervical prolaps, was not reported in two groups. Finally intra and post operative complications were more frequent in TLH."n"nConclusions: SLH is a safe an

Tehran University Medical Journal , 2012,
Abstract: Background: Gastric cancer is an important health problem across the world. Chemotherapy in combination with local treatment is the standard treatment for locally advanced gastroesophageal junction (EGJ) cancers. The purpose of this study was to evaluate response and tolerability to neoadjuvant regimen combining epirobicin, oxaliplatin and capecitabin (EOX) in locoregionally advanced gastric cancer.Methods: We recruited 28 patients with histologically confirmed advanced gastric or EGJ adenocarcinoma in this study performed in the Cancer Institute of Imam Khomeini Hospital in Tehran, Iran in 2010-2011. Staging workup included chest and abdominal computed tomography (CT) scans, upper gastrointestinal endoscopy, endoscopic ultrasonography (EUS), measurement of carcinoembryonic antigen (CEA), complete blood cell count (CBC), and liver and renal function tests. After three treatment cycles with EOX regimen, we evaluated response to the neoadjuvant chemotherapy by performing endoscopic ultrasonography (EUS) and chest and abdominal CT scans.Results: The mean age of the patients was 56.64±11.08 years (ranging from 37 to 78 years). Most patients were classified as having stage III (98.8%) cancer before chemotherapy while most were classified as stage II (57.14%) after the treatment. Only 28.5% of tumors were resectable before chemotherapy, but 82.1% of them were resectable upon the treatment. 75% of tumors were downstaged after chemotherapy.Conclusion: Regarding the acceptable response and downstaging of tumors and low toxicity of EOX regimen in locoregionally advanced gastric cancer, evaluation of this regimen as a neoadjuvant chemotherapy in larger phase III clinical trials in Iranian patients would be both necessary and logical.
Elevated CRP levels during first trimester of pregnancy and subsequent preeclampsia: a prospective study
Beigi A,Saeedi L,Samiei H,Zarrinkoub F
Tehran University Medical Journal , 2008,
Abstract: Background: Whatever its etiology, the inflammatory reactions of preeclampsia lead to the activation of endothelium and result in vascular damage. CRP is considered a sensitive index of systemic inflammation, so it is used as predictive factor for disease. This study was carried out to test the screening and predictive abilities of the CRP test in order to detect and diagnose pregnant women prone to preeclampsia prior to the onset of symptoms.Methods: In this prospective cohort study, conducted in Arash Hospital between 2005 and 2006, we determined the CRP levels of 201 pregnant women at 10-16 weeks of pregnancy. Based on exclusion criteria and illness, 31 patients were excluded and 170 patients were followed until the end of their pregnancies.Results: In this study, the mean serum CRP values of those who had preeclamptic and those who had normal pregnancies were compared and the statistical differences were significant: 6.18 mg/L for preeclamptic patients compared with 4.12 mg/L for normal patients (p=0.003). Using a chi-square test, we found that patients whose CRP level was ≥4 were six times more likely to have preeclampsia than those with CRP levels <4 (k=9.4; p=0.002; OR=6.15; 95% CI=0.69-22.28).Conclusion: This study confirms the results of previous reports indicating a significant relationship between rising serum CRP in the first trimester of pregnancy and preeclampsia at third trimester. More studies consisting of other inflammation factors are necessary to find an acceptable and reasonable screening test to diagnose pregnant women who are prone to preeclampsia.

Afsar Rouhi,Mitra Samiei
The Social Sciences , 2013, DOI: 10.3923/sscience.2010.481.485
Abstract: This study examines the effects of focused and unfocused indirect feedback on the use of simple past tense in L2 writing. About 60 Azari learners of English were assigned to a focused group, an unfocused group and a control group (20 in each). A packet including a short response test, an error correction test, a fill in the blank test and a narrative writing test was given to the participating groups. The groups turned out to be homogeneous in terms of the form in focus. Any past tense used incorrectly in the production of the participants of the focused group was underlined. All erroneous structures in the production of the unfocused group were underlined while the control group received no corrective feedback. The tests which carried feedback for the 2 experimental groups and were untouched for the control group were returned to the participants. The experimental groups were asked to reflect upon the feedback provided. The same packet of tests was given to the groups after 1 week and 3 weeks later. Split-plot ANOVAs run on the data showed that there was no statistically significant difference among the 3 groups of the study, the interaction of time and treatment was not statistically significant while the accuracy of all the 3 groups appeared to improve from time 1-2 but not from time 2-3.

Current Urban Studies (CUS) , 2016, DOI: 10.4236/cus.2016.43018
Abstract: This paper aims to prioritize intervention in urban deteriorated fabrics of Eslamshahr city. Worn-out textures in Eslamshahr (south west neighbor of Tehran), despite having potential facilities, unfortunately, in areas such as network infrastructure, water, electricity, telephone, and gas networks are becoming physical problems of the city against unforeseen events such as an earthquake. So that improvement, renovation and restoration of these textures could be very effective in making the Eslamshahr development sustainable. The studied deteriorated fabric covers an area of 104 hectares and has a population of about 42,664 people. Problems and challenges such as the domain of low-income people living, non-proportional distribution of services, marginalization and extensive urban deteriorated are among the most evident challenges. In this study, using the analytic hierarchy process (AHP), the weighting and ranking of triple structures and variables related to each structure of the worn-out texture in Eslamshahr region took place. Weighting of criteria has been carried out based on research and comment of professionals and experts. Intervention indicators in the studied fabric are recognized and prioritized based on physical, social and economic factors. Considered indicators include type of Land Use, Passage network, Building occupies, Building Density, Number of floors, Building Life, Number of blocks, Constructions materials and skeleton, Separation of parts and Building quality. After evaluation using analytical hierarchy process and according to opinions of experts, rank each of the parameters was obtained and then with using ArcGIS software overlay map have been designed and evaluated. Result of this study revealed which a pattern can be presented for intervention of worn-out texture in Eslamshahr.
The Political Participation and Government Size

Canadian Social Science , 2011,
Abstract: : This paper analyzes the effect of political participation on government size. First, the paper extends the model proposed by Mueller and Stratmann, which considers relation of political participation and government size. Second, we estimate this model with another index like democracy, voice and accountability, and Civil liberties index as political participation index. This model points that any increase in political participation is generally found to raise government size; however this increasing effect is low. Also, other considered indicators have a significant effect on government size. Our case study is the Asia and Pacific Ocean countries in during 2000 to 2008. Findings showed that when participation rate, democracy index, and voice and accountability index increase one percent, government size increases 0.065, 1.30, and 3.19 percent, respectively. Additionally, when civil liberties increases one percent, government size declines 1.29 percent. The paper provides a small expansion of Mueller and Stratmann model that considers the effect of the overall concept of political participation on government size by using indexes like democracy, voice and accountability, and Civil liberties index. Key words: Government Size; Political participation; Generalized Method of Moments (GMM) Résumé: Cet article analyse l'effet de la participation politique sur la taille du gouvernement. Tout d'abord, l'article étend le modèle concernant la participation politique et la taille du gouvernement proposé par Mueller et Stratmann. Ensuite, il évalue ce modèle avec d’autres indices comme la démocratie, le droit de parler et la responsabilité, et des indices de libertés civiles en tant que l'indice de la participation politique. Ce modèle indique que toute augmentation de la participation politique contribue généralement à élargir la taille du gouvernement, mais cet effet est faible. En outre, d'autres indicateurs estimés ont un effet significatif sur la taille du gouvernement. Notre étude de cas est menée sur les pays en Asie et dans l’océan pacifique au cours de 2000 à 2008. Les résultats ont montré que lorsque le taux de participation, l'indice de démocratie et l’indice du droit de parler et de la responsabilité augmente de 1%, la taille du gouvernement élargit de 0.065%, 1.30%, et 3.19%t, respectivement. Par contre, lorsque les libertés civiles augmente de 1%, la taille du gouvernement baisse de 1,291%. L’article fait une légère expansion du modèle de Mueller et Stratmann qui évalue l'effet de la notion globale de la participation politique sur la taille

Neda Samiei,Mohammad Reza Jalilvand
Canadian Social Science , 2011, DOI: 10.3968/j.css.1923669720110703.028
Abstract: Migration is caused by a push from behind and/or a pull from an appealing prospect in front.The combination of push and pull factors and research into which specific determinants play a significant role in migration patterns has received a lot of attention in the empirical literature. Immigration is the main demographic factor and the government is supposed to have the ability to control its size and skill composition.In high income countries natural population growth nowadays is low (or negative) and overall population growth is mostly driven by immigration. A statistically significant role of migration in affecting the tax rate is found after controlling for income inequality and for several social and demographic variables that would be expected to reflect the government‘s revenue needs and thus determine the tax rate. The aim of the present study is to examine if and how much the amount of public expenditures on social services has been affected by the migration among some Middle East countries over 1990-2007. Key words: Migration; Government size; Middle-East Résumé: La migration est causée par une poussée de l'arrière et/ou une attraction à partir d'une perspective séduisante en face.La combinaison des facteurs de poussée et tirée et la recherche sur les déterminants spécifiques jouent un r le important dans les modèles de migration.Et le problème de migration a re u beaucoup d'attention dans la littérature empirique.L'immigration est le facteur démographique principal et le gouvernement est censé avoir la capacité de contr ler sa taille et la composition des compétences.Dans les pays à revenus élevés, la croissance naturelle de la population est faible (ou négative) aujourd'hui et la croissance de la population globale est principalement influencée par l'immigration. Un r le statistiquement significatif de la migration dans l'affectation du taux d'imposition est constaté après le contr le de l'inégalité des revenus et de plusieurs variables socio-démographiques censées refléter les besoins de revenus du gouvernement et déterminer ainsi le taux d'imposition. L'objectif de la présente étude est d'examiner si et dans quelle mesure le montant des dépenses publiques consacrées dans les services sociaux a été affectée par la migration entre certains pays du Moyen-Orient durant la période 1990-2007.

Ehsan Samiei,Eric A. Butcher
Mathematics , 2015,
Abstract: The chattering response at the MRP shadow set switching point for the controlled attitude dynamics of a rigid tumbling spacecraft using delayed state feedback control with MRPs is investigated, where the time delay is assumed to be in the measurement of the state. In addition, a strategy to reduce or completely avoid the chattering phenomena using a hysteretic boundary layer switching rule is employed. Simulations are performed to demonstrate the chattering phenomenon and the advantages of the modified MRP shadow set switching rule.

PIER Letters , 2008, DOI: 10.2528/PIERL08050205
Abstract: Acompact planar microstrip ultra-wideband (UWB) bandpass filter is presented in this paper. The proposed UWB filter is realized by cascading a high pass filter (HPF) and a lowpass filter (LPF). HPF with short-circuited stubs is used to realize the lower stopband and a lowpass filter based on a defected ground array in the ground plane employed to attenuate the upper stopband. One such a bandpass filter is designed and simulated.
