| 1 | Emergency admissions due to swallowed foreign bodies in adults显示文摘AIM:To study a retrospective analysis of patients who presented to the emergency departments(ED)with complaints related to foreign body ingestions.METHODS:Patients older than 16 years of age who presented to the ED between January 1stand December 31stof 2010 with complaints related to swallowed foreign bodies were identified from electronic health records and patient charts.RESULTS:A total of 100 patients presented with a complaint of foreign body ingestion during the study period.Overall,an X-ray was performed on 75 patients,and a fiberoptic evaluation was performed on45 patients.A foreign body was detected in 46(46%)patients.The diagnostic yield of the X-ray was 27(36%)out of 75 patients,while the diagnostic yield of the fiberoptic evaluations was 21(47%)out of 45 patients.The detected foreign bodies were mostly located in the esophagus(17 out of 46 foreign bodies detected).When the types of ingested foreign bodies were evaluated,52(52%)patients reported ingesting food,and19(19%)patients reported swallowing pins.An X-ray was performed on 33 patients with accidental food ingestions but yielded a positive result in only two cases.In 12 out of 21 patients with accidental food ingestion who underwent fiberoptic evaluation,the foreign material was detected and removed.CONCLUSION:Plain radiography is helpful in the localization of radiopaque swollen foreign bodies,while fiberoptic methods are useful as both diagnostic and therapeutic tools,regardless of radiopacity. | Bülent Erbil Mehmet Ali Karaca Mehmet Ali Aslaner Zaur Ibrahimov Mehmet Mahir Kunt Erhan Akpinar Mehmet Mahir zmen | 2013 | World Journal of Gastroenterology2013，19，38： | 11 |
| 2 | Non-alcoholic fatty liver disease: What has changed in the treatment since the beginning?显示文摘Non-alcoholic fatty liver disease(NAFLD) is an umbrella term to describe the entire spectrum of this common liver disease. In patients with NAFLD, especially those with non-alcoholic steatohepatitis(NASH), most often have one or more components of the metabolic syndrome, but this is not universal. Although most patients with NAFLD share many clinical features, only a subset of patients develops significant liver inflammation and progressive fibrosis. On the other hand, not all patients with NASH exhibit insulin resistance. NASH can be seen in patients who are lean and have no identifiable risk factors. Many clinical studies have tried numerous drugs and alternative medicine, however, investigators have failed to identify a safe and effective therapy for patients with NASH. As summarized, the heterogeneity of pathogenic pathways in individual patients with NASH may warrant the development of an individualized treatment according to the underlying pathogenic pathway. The differentiation of pathogenetic targets may require the development of diagnostic and prognostic biomarkers, and the identification of genetic susceptibilities. At present, evidence-based medicine provides only a few options including life-style modifications targeting weight loss, pioglitazone and vitamin E in non-diabetic patients with biopsy-proven NASH. | Bülent Baran Filiz Akyüz | 2014 | World Journal of Gastroenterology2014，20，39： | 10 |
| 3 | 盐胁迫环境下腐植酸类物质对小麦生长及矿物营养吸收的影响显示文摘对在不同浓度的盐胁迫条件下,叶面喷施液态腐植酸和土壤施用腐植酸类物质对小麦作物生长和矿物营养吸收的影响进行了研究。通过添加不同量的NaCl得到不同的盐浓度环境。腐植酸类物质在作物种植前一个月施用,液态腐植酸在种苗发芽后20d和35d喷施于小麦叶面。腐植酸类物质的施用量为0、1g/kg、2g/kg,液态腐植酸的浓度为0、0.1%、0.2%。盐度对小麦生长具有负面影响,它会降低小麦对除Na、Mn以外的矿物营养的吸收,影响小麦干重。通过在土壤施用腐植酸类物质可以增加小麦对N的吸收,叶面施用腐植酸可增加其对P、K、Mg、Na、Cu和Zn的吸收。研究结果显示:在土壤中施用腐植酸类物质,不同盐浓度与施用量之间存在较好的相关性,但叶面喷施时盐度和喷施量之间相关性并不明显。在盐胁迫环境的影响下,叶面喷施腐植酸的初始浓度和土壤中施用的腐植酸类物质的初施量都增加了作物对营养元素的吸收。 | Bar Bülent A k Murat Ali Turan Hakan elik Ali Vahap Katkat 刘海弟 | 2009 | 腐植酸2009，，6： | 6 |

| 7 | Injection molding of micro-porous titanium alloy with space holder technique显示文摘The powder space holder(PSH) and powder injection molding(PIM) methods have an industrial competitive advantage because they are capable of the net-shape production of micro-sized porous parts.In this study,micro-porous Ti6Al4V alloy(Ti64) parts were produced by the PSH-PIM process.Ti64 alloy powder and spherical polymethylmethacrylate(PMMA) particles were used as a space holder material.After molding,binder debinding was performed by thermal method under inert gas.Debinded samples were sintered at 1250oC for 60 min in a vacuum(10-4 Pa) .Metallographic studies were conducted to determine densification and the corresponding microstructural changes.The surface of sintered samples was examined by SEM.The compressive stress and elastic modulus of the micro-porous Ti64 samples were de-termined.The effects of fraction of PMMA on the properties of sintered micro-porous Ti64 alloy samples were investigated.It was shown that the fraction of PMMA could be controlled to affect the properties of the Ti alloy. | Gülsah Engin Bülent Aydemir H.zkan Gülsoy | 2011 | Rare Metals2011，30，6： | 3 |
| 8 | Gait and Glasgow Coma Scale scores can predict functional recovery in patients with traumatic brain injury显示文摘Fifty-one patients with mild(n = 14),moderate(n = 10) and severe traumatic brain injury(n = 27) received early rehabilitation.Level of consciousness was evaluated using the Glasgow Coma Score.Functional level was determined using the Glasgow Outcome Score,whilst mobility was evaluated using the Mobility Scale for Acute Stroke.Activities of daily living were assessed using the Barthel Index.Following Bobath neurodevelopmental therapy,the level of consciousness was significantly improved in patients with moderate and severe traumatic brain injury,but was not greatly influenced in patients with mild traumatic brain injury.Mobility and functional level were significantly improved in patients with mild,moderate and severe traumatic brain injury.Gait recovery was more obvious in patients with mild traumatic brain injury than in patients with moderate and severe traumatic brain injury.Activities of daily living showed an improvement but this was insignificant except for patients with severe traumatic brain injury.Nevertheless,complete recovery was not acquired at discharge.Multiple regression analysis showed that gait and Glasgow Coma Scale scores can be considered predictors of functional outcomes following traumatic brain injury. | Sevil Bilgin Arzu Guclu-Gunduz Hakan Oruckaptan Nezire Kose Bülent Celik | 2012 | Neural Regeneration Research2012，7，25： | 3 |
| 9 | Serum beta 2-microglobulin as a biomarker in inflammatory bowel disease显示文摘AIM: To investigate the diagnostic utility of beta 2 microglobulin(B2-M) levels and analyze this correlation with the activity of inflammatory bowel disease(IBD).METHODS: Overall, 78 IBD patients and 30 healthy controls were enrolled in the study. We examined B2-M serum levels in 43 ulcerative colitis(UC) patients, 35 with Crohn's disease(CD) and 30 control subjects, using an enzymatic method. Patients were divided into two groups according to two disease types: active and in remission. Subjects were also divided into two subgroups according to extent of the disease: left-side and pancolitis for UC and ileitis and ileocolitis for CD. All groups were compared for mean serum B2-M levels and also examined to see whether there was a correlation between serum B2-M levels and other inflammatory markers.RESULTS: The mean serum B2-M levels in the control group, UC and CD were 1.71, 2.41 and 2.24 respectively. B2-M values ≥ 1.96 mg/L had a 62% sensitivity, 76% specificity, a 79% positive predictive value, and a 58% negative predictive value for UC patients. B2-Mvalues ≥ 1.70 mg/L had 80% sensitivity, 53% specificity, 66% positive predictive value, and 69% negative predictive value for CD patients. Mean B2-M values were significantly higher in ulcerative colitis and Crohn's disease patients than in healthy controls(UC 2.41 ± 0.87 vs 1.71 ± 0.44, P = 0.002; CD 2.24 ± 1.01 vs 1.71 ± 0.44, P = 0.033). Also, mean B2-M values were significantly higher in active disease when compared to patients in remission(UC 2.66 ± 0.92 vs 1.88 ± 0.41, P = 0.004; CD 2.50 ± 1.15 vs 1.73 ± 0.31, P = 0.033). The difference between groups(UC and CD) in terms of serum B2-M levels was statistically insignificant(2.41 ± 0.87 vs 2.24 ± 1.01, P > 0.05 respectively).CONCLUSION: Serum B2-M levels may be used as an activity parameter in IBD. | Bülent Y|lmaz Seyfettin Kklü Osman Yüksel Serap Arslan | 2014 | World Journal of Gastroenterology2014，20，31： | 3 |
| 10 | Gastroesophageal reflux in asymptomatic obese subjects:An esophageal impedance-pH study显示文摘AIM:To investigate the relationship between reflux and body mass index(BMI) in the asymptomatic obese population using the impedance-p H technique.METHODS:Gastroesophageal reflux is frequent in the obese population.However,the relationship between acid reflux and BMI in asymptomatic obese people is unclear.Forty-six obese(BMI > 25 kg/m2) people were enrolled in this prospective study.We evaluated the demographic findings and 24-h impedance p H values of the whole group.Gas,acid(p H < 4),weak acid(p H = 4-7) and weak alkaline(p H ≥ 7) reflux parameters were analyzed.RESULTS:The mean age of patients was 49.47±12.24 years,and half of them were men.The mean BMI was 30.64±3.95 kg/m2(25.14-45.58 kg/m2).BMI of 23 was over 30 kg/m2.Seventeen patients had a comorbidity(hypertension,diabetes mellitus,or ischemic heart disease).Endoscopic examination revealed esophagitis in 13 of the 28 subjects(10Grade A,3 Grade B).The subjects were divided into two groups according to BMI(<30 and>30 kg/m2).Demographic and endoscopic findings,and impedance results were similar in these two groups.However,there was a positive correlation between BMI and total and supine p H<4 episodes(P=0.002,r=0.414;P=0.000,r=0.542),p H<4 reflux time(P=0.015,r=0.319;P=0.003,r=0.403),and De Meester score(P=0.012,r=0.333).CONCLUSION:Acid reflux is correlated with BMI in asymptomatic obese individuals. | Filiz Akyüz Ahmet Uyanikoglu Fatih Ermis Serpil Arici ümit Akyüz Divison of Gastroenterology Department of Internal Medicine Faculty of Medicine Yeditepe University Bülent Baran Binnur Pinarbasi Nurdan Gul | 2015 | World Journal of Gastroenterology2015，21，10： | 3 |
| 11 | Determination of penetration depth at high velocity impact using finite element method and artificial neural network tools显示文摘Determination of ballistic performance of an armor solution is a complicated task and evolved significantly with the application of finite element methods(FEM) in this research field.The traditional armor design studies performed with FEM requires sophisticated procedures and intensive computational effort,therefore simpler and accurate numerical approaches are always worthwhile to decrease armor development time.This study aims to apply a hybrid method using FEM simulation and artificial neural network(ANN) analysis to approximate ballistic limit thickness for armor steels.To achieve this objective,a predictive model based on the artificial neural networks is developed to determine ballistic resistance of high hardness armor steels against 7.62 mm armor piercing ammunition.In this methodology,the FEM simulations are used to create training cases for Multilayer Perceptron(MLP) three layer networks.In order to validate FE simulation methodology,ballistic shot tests on 20 mm thickness target were performed according to standard Stanag 4569.Afterwards,the successfully trained ANN(s) is used to predict the ballistic limit thickness of 500 HB high hardness steel armor.Results show that even with limited number of data,FEM-ANN approach can be used to predict ballistic penetration depth with adequate accuracy. | Nam?k KILI?

| 12 | Investigation of impact of DC component on breakdown characteristics for different electric fields under composite AC&DC voltage显示文摘The valve side of the converter in the high‐voltage direct current is subjected to mixed voltages such as composite AC&DC voltage.In this study,the effects of the homo-geneity of electric field on breakdown voltage were investigated for different�DC component amplitudes of the composite voltage.The field efficiency factor was calcu-lated using mean and maximum field strengths for all of them.Variation of breakdown voltage of air was examined under the composite AC&DC voltage for different ratios�DC.As one result of the study,the breakdown occurs at the positive half‐wave of the AC voltage despite−DC voltage being applied due to positive corona discharge pulses.This breakdown point is named as the polarity change point.The breakdown voltage increases with the decrease of DC voltage component up to polarity change point in non‐uniform electric field.In less uniform electric field,the AC breakdown voltage was measured slightly higher than the DC breakdown voltage.In less uniform electric field,as the ratio of the applied AC voltage to DC voltage increases,the breakdown voltage gradually approaches the AC breakdown voltage.This result is similar to the result ob-tained for the+DC component in non‐uniform electric field experiments. | Mehmet Murat Ispirli Özcan Kalenderli Florian Seifert Michael Rock Bülent Oral | 2022 | High Voltage2022，7，2： | 2 |
