| 1 | Experimental study of ice accretion effects on aerodynamic performance of an NACA 23012 airfoil显示文摘In this paper,the effects of icing on an NACA 23012 airfoil have been studied.Experiments were applied on the clean airfoil,runback ice,horn ice,and spanwise ridge ice at a Reynolds number of 0.6 106 over angles of attack from 8° to 20°,and then results are compared.Generally,it is found that ice accretion on the airfoil can contribute to formation of a flow separation bubble on the upper surface downstream from the leading edge.In addition,it is made clear that spanwise ridge ice provides the greatest negative effect on the aerodynamic performance of the airfoil.In this case,the stall angle drops about 10° and the maximum lift coefficient reduces about50% which is hazardous for an airplane.While horn ice leads to a stall angle drop of about 4° and a maximum lift coefficient reduction to 21%,runback ice has the least effect on the flow pattern around the airfoil and the aerodynamic coefficients so as the stall angle decreases 2° and the maximum lift reduces about 8%. | Sohrab Gholamhosein Pouryoussefi Masoud Mirzaei Mohammad-Mahdi Nazemi Mojtaba Fouladi Alireza Doostmahmoudi | 2016 | Chinese Journal of Aeronautics2016，29，3： | 12 |
| 2 | Human embryonic stem cell-derived mesenchymal stem cells improved premature ovarian failure显示文摘BACKGROUND Premature ovarian failure(POF)affects many adult women less than 40 years of age and leads to infertility.According to previous reports,various tissue-specific stem cells can restore ovarian function and folliculogenesis in mice with chemotherapy-induced POF.Human embryonic stem cells(ES)provide an alternative source for mesenchymal stem cells(MSCs)because of their similarities in phenotype and immunomodulatory and anti-inflammatory characteristics.Embryonic stem cell-derived mesenchymal stem cells(ES-MSCs)are attractive candidates for regenerative medicine because of their high proliferation and lack of barriers for harvesting tissue-specific MSCs.However,possible therapeutic effects and underlying mechanisms of transplanted ES-MSCs on cyclophosphamide and busulfan-induced mouse ovarian damage have not been evaluated.AIM To evaluate ES-MSCs vs bone marrow-derived mesenchymal stem cells(BMMSCs)in restoring ovarian function in a mouse model of chemotherapy-induced premature ovarian failure.METHODS Female mice received intraperitoneal injections of different doses of cyclophosphamide and busulfan to induce POF.Either human ES-MSCs or BMMSCs were transplanted into these mice.Ten days after the mice were injected with cyclophosphamide and busulfan and 4 wk after transplantation of the ESMSCs and/or BM-MSCs,we evaluated body weight,estrous cyclicity,folliclestimulating hormone and estradiol hormone concentrations and follicle count were used to evaluate the POF model and cell transplantation.Moreover,terminal deoxynucleotidyl transferase mediated 2-deoxyuridine 5-triphosphate nick end labeling,real-time PCR,Western blot analysis and immunohistochemistry and mating was used to evaluate cell transplantation.Enzyme-linked immunosorbent assay was used to analyze vascular endothelial growth factor,insulin-like growth factor 2 and hepatocyte growth factor levels in ES-MSC condition medium in order to investigate the mechanisms that underlie their function.RESULTS The human ES-MSCs significantly restored hormone secretion,survival rate and reproductive function in POF mice,which was similar to the results obtained with BM-MSCs.Gene expression analysis and the terminal deoxynucleotidyl transferase mediated 2-deoxyuridine 5-triphosphate nick end labeling assay results indicated that the ES-MSCs and/or BM-MSCs reduced apoptosis in the follicles.Notably,the transplanted mice generated new offspring.The results of different analyses showed increases in antiapoptotic and trophic proteins and genes.CONCLUSION These results suggested that transplantation of human ES-MSCs were similar to BM-MSCs in that they could restore the structure of the injured ovarian tissue and its function in chemotherapy-induced damaged POF mice and rescue fertility.The possible mechanisms of human ES-MSC were related to promotion of follicular development,ovarian secretion,fertility via a paracrine effect and ovarian cell survival. | Khadijeh Bahrehbar Mojtaba Rezazadeh Valojerdi Fereshteh Esfandiari Rouhollah Fathi Seyedeh-NafisehHassani Hossein Baharvand | 2020 | World Journal of Stem Cells2020，12，8： | 12 |
| 3 | Endoscopic ultrasound:It’s accuracy in evaluating mediastinal lymphadenopathy? A meta-analysis and systematic review显示文摘AIM:To evaluate the accuracy of endoscopic ultrasound (EUS), EUS-fine needle aspiration (FNA) in evaluating mediastinal lymphadenopathy. METHODS:Only EUS and EUS-FNA studies confirmed by surgery or with appropriate follow-up were selected. Articles were searched in Medline, Pubmed, and Cochrane control trial registry. Only studies from which a 2 × 2 table could be constructed for true positive, false negative, false positive and true negative values were included. Two reviewers independently searched and extracted data. The differences were resolved by mutual agreement. Meta-analysis for the accuracy of EUS was analyzed by calculating pooled estimates of sensitivity, specificity, likelihood ratios, and diagnostic odds ratios. Pooling was conducted by both Mantel-Haenszel method (fixed effects model) and DerSimonian Laird method (random effects model). The heterogeneity of studies was tested using Cochran’s Q test based upon inverse variance weights. RESULTS:Data was extracted from 76 studies (n = 9310) which met the inclusion criteria. Of these, 44 studies used EUS alone and 32 studies used EUS-FNA. FNA improved the sensitivity of EUS from 84.7% (95% CI:82.9-86.4) to 88.0% (95% CI:85.8-90.0). With FNA, the specificity of EUS improved from 84.6% (95% CI:83.2-85.9) to 96.4% (95% CI:95.3-97.4). The P forchi-squared heterogeneity for all the pooled accuracy estimates was > 0.10. CONCLUSION:EUS is highly sensitive and specific for the evaluation of mediastinal lymphadenopathy and FNA substantially improves this. EUS with FNA should be the diagnostic test of choice for evaluating mediastinal lymphadenopathy. | Srinivas R Puli Jyotsna Batapati Krishna Reddy Matthew L Bechtold Jamal A Ibdah Daphne Antillon Shailender Singh Mojtaba Olyaee Mainor R Antillon | 2008 | World Journal of Gastroenterology2008，14，19： | 10 |
| 4 | 高强电场中液滴静电运动特性显示文摘针对油田生产中含表面活性剂原油电脱水极为困难,缺乏理论指导的现状,采用动态微观实验的方法,研究含表面活性剂的油水系统中液滴在电场力作用下聚并排液的情况,计算液滴的聚结时间,并观测液滴发生形变直至破裂时各个阶段的现象。结果表明,表面活性剂可引起液滴界面排斥力上升,聚并过程中液面出现形变,降低液滴聚结速度。此外,液滴表面所吸附的表面活性剂分子会加剧液滴形变率,降低液滴破裂所需临界场强,并改变液滴破裂机制,增加了次级微小液滴的产生。须严格控制电场强度,以避免液滴变形破裂,提高聚结效率,确保电脱水的效果。 | 张黎明 张凯 李晓帆 Mojtaba Ghadiri Ali Hassanpour | 2011 | 石油学报2011，32，3： | 10 |
| 5 | White-to-white corneal diameter: normal values in healthy Iranian population obtained with the Orbscan II显示文摘AIM:To determine the normative values of white-towhite corneal diameter with Orbscan II Topography System and to compare right and left eyes data in the normal young population.METHODS:A total of 1001 healthy participants aged18-45y participated in this observational cross-sectional study.The study population consisted of 616 female and385 male subjects.The corneal diameter was measured with the Orbscan II.The differences between genders,between right and left eyes and age-related changes were evaluated.Statistical analyses were performed using Student's t-test.RESULTS:The average white-to-white distance in our study population was recorded as 11.65±0.36 mm(median:11.60 mm,mode:11.70 mm,minimum:10.50mm and maximum:13.60 mm).The white-to-white distance was 11.60±0.35 mm in males and 11.71±0.36 mm in females which was statistically different between genders(P<0.01).However,white-to-white distance was not statistically different between right and left eyes.In addition,this parameter decreased with increasing age.Considering 95%confidence interval,corneal diameter less than 10.93 mm and greater than 12.34 mm would be considered as microcornea and megalocornea,respectively based on this study population,using the Orbscan II topography.CONCLUSION:Detailed description and analysis of corneal diameter with Orbscan demonstrate that the obtained average value of horizontal white-to-white is higher in male than female and decreases slightly with increasing age.Our data also suggests the cut off values for definition of microcornea and megalocornea,which can be employed with this population. | Hamid Gharaee Mojtaba Abrishami Masoud Shafiee Asieh Ehsaei | 2014 | International Journal of Ophthalmology(English edition)2014，7，2： | 9 |
| 6 | Fatty liver index vs waist circumference for predicting non-alcoholic fatty liver disease显示文摘AIM: To determine the discriminatory performance of fatty liver index(FLI) for non-alcoholic fatty liver disease(NAFLD).METHODS: The data of 5052 subjects aged over 18 years were analyzed. FLI was calculated from body mass index, waist circumference(WC), triglyceride, and gamma glutamyl transferase data. Logistic regression analysis was conducted to determine the association between FLI and NAFLD. The discriminatory performance of FLI in the diagnosis of NAFLD was evaluated by receiver operating characteristic analysis. Area under the curves(AUCs) and related confidence intervals were estimated. Optimal cutoff points of FLI in the diagnosis of NAFLD were determined based on the maximum values of Youden's index.RESULTS: The mean age of men and women in the study population were 44.8 ± 16.8 and 43.78 ± 15.43, respectively(P = 0.0216). The prevalence of NAFLD was 40.1% in men and 44.2% in women(P < 0.0017). FLI was strongly associated with NAFLD, so that even a one unit increase in FLI increased the chance of developing NAFLD by 5.8%(OR = 1.058, 95%CI: 1.054-1.063, P < 0.0001). Although FLI showed good performance in the diagnosis of NAFLD(AUC = 0.8656(95%CI: 0.8548-0.8764), there was no significant difference with regards to WC(AUC = 0.8533, 95%CI: 0.8419-0.8646). The performance of FLI was not significantly different between men(AUC = 0.8648, 95%CI: 0.8505-0.8791) and women(AUC = 0.8682, 95%CI: 0.8513-0.8851). The highest performance with regards to age was related to the 18-39 age group(AUC = 0.8930, 95%CI: 0.8766-0.9093). The optimal cutoff points of FLI were 46.9 in men(sensitivity = 0.8242, specificity = 0.7687, Youden's index = 0.5929) and 53.8 in women(sensitivity = 0.8233, specificity = 0.7655, Youden's index = 0.5888).CONCLUSION: Although FLI had acceptable discriminatory power in the diagnosis of NAFLD, WC was a simpler and more accessible index with a similar performance. | Nima Motamed Masoudreza Sohrabi Hossein Ajdarkosh Gholamreza Hemmasi Mansooreh Maadi Fatemeh Sima Sayeedian Reza Pirzad Khadijeh Abedi Sivil Aghapour Mojtaba Fallahnezhad Farhad Zamani | 2016 | World Journal of Gastroenterology2016，22，10： | 8 |
| 7 | Effect of sex and rearing system on the quality and mineral content of fiber from raeini cashmere goats显示文摘The aim of this study was to compare the quality characteristics and mineral content of the fiber from male and female cashmere goats raised under different management systems. Male and female Raeini cashmere goats (<1.5 years of age, n = 48) were selected from flocks raised at a government breeding station or raised commercially under either rural or nomadic conditions. The staple length, cashmere fiber diameter, coefficient of variation for fiber diameter, percentage of cashmere in a fleece, percentage of guard hair in a fleece and cashmere tenacity averaged 4.6 ±0.1 cm, 18.0 ±0.1 m, 20.9 ± 0.4%, 66.1 ± 1.5%, 33.8 ± 1.5% and 1.8 ± 0.2 gf/tex, respectively. The sulfur, copper and zinc content of the cashmere averaged 2.8 ± 0.1%, 0.00065 ± 0.00002% and 0.01276 ± 0.00025%, respectively. Rearing method significantly affected staple length, coefficient of variation of fiber diameter, cashmere tenacity and copper content. Males had a higher coefficient of variation of fiber diameter and cashmere tenacity than females (P < 0.05). | Mehrdad Shamsaddini-Bafti Mahnaz Salehi Ali Maghsoudi Ali Mostafa Tehrani Farhad Mirzaei Syed Mojtaba Syed Momen | 2012 | Journal of Animal Science and Biotechnology2012，3，3： | 7 |
| 8 | 12 hours after cerebral ischemia is the optimal time for bone marrow mesenchymal stem cell transplantation显示文摘Cell therapy using stem cell transplantation against cerebral ischemia has been reported. However, it remains controversial regarding the optimal time for cell transplantation and the transplantation route. Rat models of cerebral ischemia were established by occlusion of the middle cerebral artery. At 1, 12 hours, 1, 3, 5 and 7 days after cerebral ischemia, bone marrow mesenchymal stem cells were injected via the tail vein. At 28 days after cerebral ischemia, rat neurological function was evaluated using a 6-point grading scale and the pathological change of ischemic cerebral tissue was observed by hematoxylin-eosin staining. Under the fluorescence microscope, the migration of bone marrow mesenchymal stem cells was examined by PKH labeling. Caspase-3 activity was measured using spectrophotometry. The optimal neurological function recovery, lowest degree of ischemic cerebral damage, greatest number of bone marrow mesenchymal stem cells migrating to peri-ischemic area, and lowest caspase-3 activity in the ischemic cerebral tissue were observed in rats that underwent bone marrow mesenchymal stem cell transplantation at 12 hours after cerebral ischemia. These findings suggest that 12 hours after cerebral ischemia is the optimal time for tail vein injection of bone marrow mesenchymal stem cell transplantation against cerebral ischemia, and the strongest neuroprotective effect of this cell therapy appears at this time. | Seyed Mojtaba Hosseini Mohammad Farahmandnia Zahra Razi Somayeh Delavarifar Benafsheh Shakibajahromi | 2015 | Neural Regeneration Research2015，10，6： | 7 |

| 15 | Complementary and alternative medicine use in Iranian patients with diabetes mellitus显示文摘OBJECTIVE: There is increasing interest in complementary and alternative medicine generally, and especially by those affected by chronic diseases, such as diabetes mellitus. We aimed to determine the prevalence and pattern of complementary and alternative medicine use among patients suffering from diabetes mellitus in Shiraz, southern Iran. Another objective was to explore associated factors for use of complementary and alternative medicine among patients with diabetes mellitus.METHODS: A 19-item semi-structured questionnaire(open- and close-ended) was administered to 239 patients with diabetes mellitus in this cross-sectional study. It was carried out in two outpatient diabetes clinics affiliated with the Shiraz University of Medical Sciences, Shiraz, Iran.RESULTS: One hundred and eighty patients(75.3%) used at least one type of complementary and alternative medicine in the last year prior to the interview. Patients with diabetes mellitus who were living in a large family(≥ 5 members), not taking insulin, and believed that complementary and alternative medicine have synergistic effects with conventional medicine, were independently and significantly(P values: 0.02, 0.04, and 0.01, respectively) more likely to use complementary and alternative medicine. Most of the users(97.7%) reported use of herbal preparations, and 89.4% of users did not change their medication, neither in medication schedule nor its dosage.CONCLUSION: The use of complementary and alternative medicine, especially herbal remedies, is popular among diabetes patients in Shiraz, Iran. This use is associated with patients' family size, type of conventional medications and their view about concomitant use of complementary and conventional medicine. | Mohammad Hashem Hashempur Mojtaba Heydari Seyed Hamdollah Mosavat Seyyed Taghi Heydari Mesbah Shams | 2015 | Journal of Integrative Medicine2015，13，5： | 5 |
| 16 | Simultaneous detection and differentiates of Brucella abortus and Brucella melitensis by combinatorial PCR显示文摘Objective:To evaluate simultaneous detection and differentiates of Brucella abortus(B.abortus) and Brucella melitensis(B.melitensis) through the combinatorial POR method.Methods:This study was designed using three primers that could simultaneously identify and differentiate two major species of pathogenic Brucella in humans and animals.Identification and differentiation of each species using the size of the PCR product were determined.To determine the specifieity of the method,bacteria close to the genus Brucella were used.Finally,to confirm PCR products.In addition to the products sequence,RFLP was performed on PCR products using restriction enzymes.Results:The method of optimized combinatorial PCR in this study could simultaneously detect and differentiate B.abortus and B.melitensis with high specificity and sensitivity in clinical samples.Differentiation of species is based on the resulting bands: therefore,the band 494 bp for B.abortus and 733 bp for B.melitensis were obtained.RFLP and sequencing results confirmed PCR results.Conclusions:The results of this study shows that without routine diagnostic methods such as culture and serology tests,using the molecular method of combinatorial PCR,important species of Brucella can be simultaneously identified and differentiated in clinical samples. | Reza Mirnejad Reza Hosseini Doust Reza Kachuei Seied Mojtaba Mortazavi Mehdi Khoobdel Ali Ahamadi | 2012 | Asian Pacific Journal of Tropical Medicine2012，5，1： | 5 |
| 17 | Determining the spatial distribution of soil properties using the environmental covariates and multivariate statistical analysis: a case study in semi-arid regions of Iran显示文摘Natural soil-forming factors such as landforms, parent materials or biota lead to high variability in soil properties. However, there is not enough research quantifying which environmental factor(s) can be the most relevant to predicting soil properties at the catchment scale in semi-arid areas. Thus, this research aims to investigate the ability of multivariate statistical analyses to distinguish which soil properties follow a clear spatial pattern conditioned by specific environmental characteristics in a semi-arid region of Iran. To achieve this goal, we digitized parent materials and landforms by recent orthophotography. Also, we extracted ten topographical attributes and five remote sensing variables from a digital elevation model(DEM) and the Landsat Enhanced Thematic Mapper(ETM), respectively. These factors were contrasted for 334 soil samples(depth of 0–30 cm). Cluster analysis and soil maps reveal that Cluster 1 comprises of limestones, massive limestones and mixed deposits of conglomerates with low soil organic carbon(SOC) and clay contents, and Cluster 2 is composed of soils that originated from quaternary and early quaternary parent materials such as terraces, alluvial fans, lake deposits, and marls or conglomerates that register the highest SOC content and the lowest sand and silt contents. Further, it is confirmed that soils with the highest SOC and clay contents are located in wetlands, lagoons, alluvial fans and piedmonts, while soils with the lowest SOC and clay contents are located in dissected alluvial fans, eroded hills, rock outcrops and steep hills. The results of principal component analysis using the remote sensing data and topographical attributes identify five main components, which explain 73.3% of the total variability of soil properties. Environmental factors such as hillslope morphology and all of the remote sensing variables can largely explain SOC variability, but no significant correlation is found for soil texture and calcium carbonate equivalent contents. Therefore, we conclude that SOC can be considered as the best-predicted soil property in semi-arid regions. | Mojtaba ZERAATPISHEH Shamsollah AYOUBI Magboul SULIEMAN JesusRODRIGO-COMINO | 2019 | Journal of Arid Land2019，11，4： | 5 |
| 18 | Fuzzy expert system for diagnosing diabetic neuropathy显示文摘AIM To design a fuzzy expert system to help detect and diagnose the severity of diabetic neuropathy. METHODS The research was completed in 2014 and consisted of two main phases. In the first phase, the diagnostic parameters were determined based on the literature review and by investigating specialists' perspectives(n= 8). In the second phase, 244 medical records related to the patients who were visited in an endocrinology and metabolism research centre during the first six months of 2014 and were primarily diagnosed with diabetic neuropathy, were used to test the sensitivity, specificity, and accuracy of the fuzzy expert system.RESULTS The final diagnostic parameters included the duration of diabetes, the score of a symptom examination based on the Michigan questionnaire, the score of a sign examination based on the Michigan questionnaire, the glycolysis haemoglobin level, fasting blood sugar, blood creatinine, and albuminuria. The output variable was the severity of diabetic neuropathy which was shown as a number between zero and 10, had been divided into four categories: absence of the disease,(the degree of severity) mild, moderate, and severe. The interface of the system was designed by ASP.Net(Active Server Pages Network Enabled Technology) and the system function was tested in terms of sensitivity(true positive rate)(89%), specificity(true negative rate)(98%), and accuracy(a proportion of true results, both positive and negative)(93%).CONCLUSION The system designed in this study can help specialistsand general practitioners to diagnose the disease more quickly to improve the quality of care for patients. | Meysam Rahmani Katigari Haleh Ayatollahi Mojtaba Malek Mehran Kamkar Haghighi | 2017 | World Journal of Diabetes2017，8，2： | 5 |
| 19 | GPGPU-parallelised hybrid finite-discrete element modelling of rock chipping and fragmentation process in mechanical cutting显示文摘Mechanical cutting provides one of the most flexible and environmentally friendly excavation methods.It has attracted numerous efforts to model the rock chipping and fragmentation process,especially using the explicit finite element method(FEM) and bonded particle model(BPM),in order to improve cutting efficiency.This study investigates the application of a general-purpose graphic-processing-unit parallelised hybrid finite-discrete element method(FDEM) which enjoys the advantages of both explicit FEM and BPM,in modelling the rock chipping and fragmentation process in the rock scratch test of mechanical rock cutting.The input parameters of FDEM are determined through a calibration procedure of modelling conventional Brazilian tensile and uniaxial compressive tests of limestone,A series of scratch tests with various cutting velocities,cutter rake angles and cutting depths is then modelled using FDEM with calibrated input parameters.A few cycles of cutter/rock interactions,including their engagement and detachment process,are modelled for each case,which is conducted for the first time to the best knowledge of the authors,thanks to the general purpose graphic processing units(GPGPU) parallelisation.The failure mechanism,cutting force,chipping morphology and effect of various factors on them are discussed on the basis of the modelled results.Finally,it is concluded that GPGPU-parallelised FDEM provides a powerful tool to further study rock cutting and improve cutting efficiencies since it can explicitly capture different fracture mechanisms contributing to the rock chipping as well as chip formation and the separation process in mechanical cutting.Moreover,it is concluded that chipping is mostly owed to the mix-mode Ⅰ-Ⅱ fracture in all cases although mode Ⅱ cracks and mode Ⅰ cracks are the dominant failures in rock cutting with shallow and deep cutting depths,respectively.The chip morphology is found to be a function of cutter velocdty,cutting depth and cutter rake angle. | Mojtaba Mohammadnejad Sevda Dehkhoda Daisuke Fukuda Hongyuan Liu Andrew Chan | 2020 | Journal of Rock Mechanics and Geotechnical Engineering2020，12，2： | 5 |
