| 1 | Progress in surgical and nonsurgical approaches for hepatocellular carcinoma treatment显示文摘BACKGROUND:Hepatocellular carcinoma(HCC) is a complex and heterogeneous malignancy,frequently occurs in the setting of a chronically diseased organ,with multiple confounding factors making its management challenging.HCC represents one of the leading causes of cancer-related mortality globally with a rising trend of incidence in some of the developed countries,which indicates the need for better surgical and nonsurgical management strategies.DATA SOURCES:Pub Med database was searched for relevant articles in English on the issue of HCC management.RESULTS:Surgical resection represents a potentially curative option for appropriate candidates with tumors detected at earlier stages and with well-preserved liver function.The long-term outcome of surgery is impaired by a high rate of recurrence.Surgical approaches are being challenged by local ablative therapies such as radiofrequency ablation and microwave ablation in selected patients.Liver transplantation offers potential cure for HCC and also correction of underlying liver disease,and minimizes the risk of recurrence,but is reserved for patients within a set of criteria proposed for a prudent allocation in the shortage of donor organs.Transcatheter locoregional therapies have become the palliative standard allowing local control for intermediate stage patients with noninvasive multinodular or large HCC who are beyond the potentially curative options.The significant survival benefit with the multikinase inhibitor sorafenib for advanced HCC has shifted the direction of research regarding systemic treatment toward molecular therapies targeting the disregulated pathways of hepatocarcinogenesis.Potential benefit is suggested from simultaneous or sequential multimodal therapies,and optimal combinations are being investigated.Despite the striking progress in preclinical studies of HCC immunotherapy and gene therapy,extensive clinical trials are required to achieve successful clinical applications of these innovative approaches.CONCLUSION:Treatment decisions have become increasingly complex for HCC with the availability of multiple surgical and nonsurgical therapeutic options and require a comprehensive,multidisciplinary approach. | Ender Gunes Yegin Erkan Oymac1 Emrah Karatay Ahmet Coker | 2016 | Hepatobiliary & Pancreatic Diseases International2016，15，3： | 14 |
| 2 | The assessment of structural changes on optic nerve head and macula in primary open angle glaucoma and ocular hypertension显示文摘AIM:To assess morphological changes in macula, retinal nerve fiber layer (RNFL) and optic nevre head (ONH) of cases with primary open angle glaucoma (POAG) and ocular hypertension (OH) with spectral domain optic coherence tomography (OCT).METHODS:This study included 109 eyes from 62 POAG patients, 50 eyes from 30 OH patients, and 101 eyes from 53 healthy volunteers. Data gained by OCT were compared with perimetry indexes. ONH, RNFL and macula analysis were performed for all subjects. Rim area, disc area,average cup/disc (C/D) ratio, vertical C/D ratio, cup volume data were recorded during ONH analysis. Average RNFL thickness and the thickness of four quadrants (superior,inferior, nasal and temporal) was established in microns.In total, nine macular quadrants involving the foveal region mentioned in the Early Treatment Diabetic Treatment Study(ETDRS) template were measured, and average macular thickness and macular volume data were recorded during macula analysis. Differences between groups were evaluated with the one-way ANOVA test. Tukey’s multiple comparison test was performed to detect difference between groups.Receiver-operating characteristic (ROC) analysis was done for early stage POAG patients to establish sensitivity and specificity of chosen parameters in early stage POAG.Area under the receiver operating characteristic (AUROC)values were calculated to compare ROC areas.RESULTS:Statistically significant differences were found in all ONH parameters, except optic disc area. Neuroretinal rim area was identified as the parameter with the highest difference between groups (F=21.72, P<0.05). The highest correlation between ONH parameters and perimetry was observed at neuroretinal rim region (r=0.487). Inferior RNFL thickness was established as the parameter with the highest difference between groups among RNFL parameters. In the mean of all glaucoma patients, the highest correlation between data handled with OCT and mean deviation was observed in RNFL thickness. Average macular thickness was detected as the parameter with the highest difference between groups among macular parameters. The highest correlation between macula parameters and perimetry indexes was observed between average macular thickness and perimetry indexes (r=0.514).CONCLUSION:Although the assessment of ONH and the analysis of macular thickness are important in diagnosis and treatment, RNFL assessment is the most valuable parameter. | Kenan Dagdelen Emrah Dirican | 2018 | International Journal of Ophthalmology(English edition)2018，11，10： | 8 |

| 4 | Clustering Seismic Activities Using Linear and Nonlinear Discriminant Analysis显示文摘Identification and classification of different seismo-tectonic events with similar characteristics in a region of interest is one of the most important subjects in seismic hazard studies.In this study,linear and nonlinear discriminant analyses have been applied to classify seismic events in the vicinity of Istanbul.The vertical components of the digital velocity seismograms are used for seismic events with magnitude(Md)between 1.8 and 3.0 that occurred between 2001 and 2004.Two,time dependent parameters,complexity and S/P peak amplitude ratio are selected as predictands.Linear,quadratic,diaglinear and diagquadratic discriminant functions are investigated.Accuracy of methods with an additional adjusted quadratic models are 96.6%,96.6%,95.5%,96.6%,and 97.6%,respectively with a various misclassified rate for each class.The performances of models are justified with cross validation and resubstitution error.Although all models remarkably well performed,adjusted quadratic function achieved the best success rate with just 4 misclassified events out of 179,even better compared to complex methods such as,self organizing method,k-means,Gaussion mixture models that applied to same dataset in literature. | H Serdar Kuyuk Eray Yildirim Emrah Dogan Gunduz Horasan | 2014 | Journal of Earth Science2014，25，1： | 4 |
| 5 | Pancreatic extragastrointestinal stromal tumor:A case report and comprehensive literature review显示文摘AIM: To provide an overview of the literature on pan-creatic extragastrointestinal stromal tumors(EGISTs).METHODS: We report a case of pancreatic EGIST and review published studies on pancreatic EGIST ac-cessed via the PubMed, MEDlInE, Google Scholar, and Google databases. The keywords used were 'pancreas and GIST', 'pancreas and extra GIST', 'pancreas and gastrointestinal stromal tumor', and 'pancreas and ex-tragastrointestinal stromal tumor'. literature reviews and/or duplicate studies were excluded. The search included articles published in the English language be-tween January 1, 2000 and May 15, 2014.RESULTS: From our literature survey, 30 manuscripts on pancreatic EGISTs were considered, of which 27met the search criteria and three were excluded. The studies involved 30 patients(15 men, 15 women) with a mean age of 55.3 ± 14.3 years(range 30-84 years). The mean age of the male patients was 50.8 ± 13.7 years(range 30-84 years); that of the female patients was 59.9 ± 13.3 years(range 38-81 years). Tumor dimensions were obtained for 28 cases(mean 114.4 ± 78.6 mm; range 20-350 mm). Tumors were diagnosed incidentally in 23.3% of patients; abdominal discomfort and weight loss were the major complaints in symp-tomatic patients. Risk of aggressive behavior according to Fletcher criteria was determined in 25 of 30 patients(68%: high risk, 28%: intermediate risk, 4%: low risk). Histopathological examination revealed the presence of spindle cells in 96.1% of cases; CD117 and CD34 were present immunohistochemically in 96.6% and 84% of patients, respectively. The most common surgical pro-cedures were distal pancreatectomy with splenectomy(n = 9) and pancreaticoduodenectomy(n = 7). The to-tal follow-up period for the 28 patients ranged from 3-66 mo, during which locoregional or distant metastases were diagnosed in six patients and two patients died.CONCLUSION: Studies on EGISTs have only been published in the last decade. The lack of studies with large patient cohorts and long-term follow-up limits evidence-based commentary. In theory, each case should be assessed individually and further genetic and immunohistochemical studies are needed. | Sami Akbulut Rdvan Yavuz Emrah Otan Sinan Hatipoglu | 2014 | World Journal of Gastrointestinal Surgery2014，6，9： | 4 |

| 9 | Differences in individual susceptibility affect the development of trigeminal neuralgia显示文摘Trigeminal neuralgia is a syndrome due to dysfunctional hyperactivity of the trigeminal nerve,and is characterized by a sudden,usually unilateral,recurrent lancinating pain arising from one or more divisions of the nerve.The most accepted pathogenetic mechanism for trigeminal neuralgia is compression of the nerve at its dorsal root entry zone or in its distal course.In this paper,we report four cases with trigeminal neuralgia due to an unknown mechanism after an intracranial intervention.The onset of trigeminal neuralgia after surgical interventions that are unrelated to the trigeminal nerve suggests that in patients with greater individual susceptibility,nerve contact with the vascular structure due to postoperative pressure and changes in cerebrospinal fluid flow may cause the onset of pain. | Yusuf Kurtulus Duransoy Mesut Mete Emrah Akay Mehmet Seluki | 2013 | Neural Regeneration Research2013，8，14： | 3 |
| 10 | Endoscopic ear surgery显示文摘Objectives:This article reviews the advantages and disadvantages of endoscopic ear surgery(EES).Method:Pubmed,Google and the Proquest Central Database at Kirikkale University were queried using the keywords'endoscopic ear surgery','ear surgery'and'endoscopy'to identify the literature needed for the review.Results:Endoscopes allow for enhanced surgical visualisation.The distal part of the apparatus is illuminated and contains lenses angled to allow a wider view of the operative area.Transcanal endoscopic techniques have transformed the external ear canal(EAC)into an operative gateway.The benefits EES can offer include wider views,enhanced imaging capabilities and increased magnification,and ways to see otherwise poorly visualisable portions of the middle ear.EES permits surgeons to operate using minimally invasive otological techniques.When compared with microscope-assisted surgery,endoscopic tympanoplasty has been shown to require a shorter operating time in some instances.There are a number of drawbacks to EES,however,which include the fact that it is a single-handed technique,that the light source may produce thermal injury and that visualisation using the endoscope is severely curtailed if bleeding is profuse.Conclusion:EES is a safe and effective technique.The current literature supports the idea that the results achieved by endoscopic methods are usually comparably beneficial to results obtained using conventional microscopic methods. | Ismet Emrah Emre Cemal Cingi Nuray Bayar Muluk Joao Flaavio Nogueira | 2020 | Journal of Otology2020，15，1： | 3 |
| 11 | Investor sentiments and stock marketsduring the COVID-19 pandemic显示文摘This study examines the relationship between positive and negative investor sentiments and stock market returns and volatility in Group of 20 countries using variousmethods, including panel regression with fixed effects, panel quantile regressions, apanel vector autoregression (PVAR) model, and country-specific regressions. We proxyfor negative and positive investor sentiments using the Google Search Volume Indexfor terms related to the coronavirus disease (COVID-19) and COVID-19 vaccine, respectively. Using weekly data from March 2020 to May 2021, we document significantrelationships between positive and negative investor sentiments and stock marketreturns and volatility. Specifically, an increase in positive investor sentiment leads toan increase in stock returns while negative investor sentiment decreases stock returnsat lower quantiles. The effect of investor sentiment on volatility is consistent acrossthe distribution: negative sentiment increases volatility, whereas positive sentimentreduces volatility. These results are robust as they are corroborated by Granger causalitytests and a PVAR model. The findings may have portfolio implications as they indicatethat proxies for positive and negative investor sentiments seem to be good predictorsof stock returns and volatility during the pandemic. | Emre Cevik Buket Kirci Altinkeski Emrah Ismail Cevik Sel Dibooglu | 2022 | Financial Innovation2022，8，1： | 2 |
| 12 | Malformations of cortical development:3T magnetic resonance imaging features显示文摘Malformation of cortical development(MCD) is a term representing an inhomogeneous group of central nervous system abnormalities, referring particularly to embriyological aspect as a consequence of any of the three developmental stages, i.e., cell proliferation, cell migration and cortical organization. These include cotical dysgenesis, microcephaly, polymicrogyria, schizencephaly, lissencephaly, hemimegalencephaly, heterotopia and focal cortical dysplasia. Since magnetic resonance imaging is the modality of choice that best identifies the structural anomalies of the brain cortex, we aimed to provide a mini review of MCD by using 3T magnetic resonance scanner images. | Bilal Battal Selami Ince Veysel Akgun Murat Kocaoglu Emrah Ozcan Mustafa Tasar | 2015 | World Journal of Radiology2015，7，10： | 2 |
| 13 | Flexible supercapacitor electrodes with vertically aligned carbon nanotubes grown on aluminum foils显示文摘In this work, vertically aligned carbon nanotubes(VACNTs) grown on aluminum foils were used as flexible supercapacitor electrodes. Aluminum foils were used as readily available, cheap and conductive substrates, and VACNTs were grown directly on these foils through chemical vapor deposition(CVD)method. Solution based ultrasonic spray pyrolysis(USP) method was used for the deposition of the CNT catalyst. Direct growth of VACNTs on aluminum foils ruled out both the internal resistance of the supercapacitor electrodes and the charge transfer resistance between the electrode and electrolyte. A specific capacitance of 2.61 m F/cm^2 at a scan rate of 800 m V/s was obtained from the fabricated electrodes, which is further improved through the bending cycles. | Itir Bakis Dogru Mete Batuhan Durukan Onur Turel Husnu Emrah Unalan | 2016 | Progress in Natural Science:Materials International2016，26，3： | 2 |
| 14 | Isolation and diagnosis of Helicobacter pylori by a new method: Microcapillary culture显示文摘AIM:To investigate the performance of the microcapillary culture method(MCM) in Helicobacter pylori(H.pylori) isolation and diagnosis.METHODS:Microcapillary culture(MC),classical culture(CC),rapid urease(CLO) test,and histopathologic examination(HE) were performed with biopsy samples.Homogenized biopsy samples were loaded into capillary tubes and incubated for 48 h at 37 ℃ without providing a microaerophilic environment.Additionally,three or four loops of the homogenized sample were inoculated in a ready-to-use selective medium(Becton Dickinson,Helicobacter Agar,Modified) specific for the isolation of H.pylori and incubated at 37 ℃ in a microaerophilic atmosphere provided by Campy Gen(Becton Dickinson,Gas Pack).Bacteria reproducing in microcapillary tubes were evaluated in an inverted microscope and also were evaluated after performing a CC with the content.Results obtained by CC,CLO test,and HE were compared with those of MC.The diagnostic performances of the methods used in this study were evaluated for specificity,sensitivity,positive predictive value(PPV),negative predictive value(NPV),and CI.RESULTS:H.pylori was found positive by CLO test +HE and/or CC culture in 26 patient antrum and corpus biopsy samples.In 25(25/26) patient biopsy samples,H.pylori was isolated by MCM,whereas in only 14(14/26) patient biopsy samples,H.pylori was isolatedby CC.CLO test and HE were found positive in 17(17/26) patient biopsy samples.Comparing the results of the isolation of H.pylori by MCM,CC,CLO test,and HE,the sensitivity of the MCM was found as 96%,the specificity as 80%,the PPV as 83%,the NPV as 95%,and the 95%CI as 0.76(χ2 =31.51,P < 0.01) whereas the sensitivity of the CC was found as 54%(χ2 =19.15,P < 0.01),and the sensitivity of the CLO test and HE were found as 65%(χ2 =25.26,P < 0.01).CONCLUSION:This new microcapillary cultivation method for H.pylori has high diagnostic sensitivity compared with CC,HE,and CLO tests. | Adil M Allahverdiyev Melahat Bagirova Reyhan Caliskan Hrisi Bahar Tokman Hayat Aliyeva Gokce Unal Olga Nehir Oztel Emrah Sefik Abamor Hilal Toptas Pelin Yuksel Fatma Kalayci Mustafa Aslan Yusuf Erzin Kadir Bal Bekir S Kocazeybek | 2015 | World Journal of Gastroenterology2015，21，9： | 2 |

| 16 | A framework for ICT-enabled real-time production planning and control显示文摘This paper aims to develop a conceptual framework for real-time production planning and control(PPC).Firstly,we discuss the most prominently applied contemporary information and communication technologies for PPC.Enterprise resource planning(ERP) systems that integrate the value chain in an enterprise,manufacturing execution systems that manage and control the production on shopfloor,and advanced planning and scheduling(APS)systems that develop solutions for complex planning problems are the planning and control systems that have been analyzed.We emphasize the application of radio frequency identification as the most advanced and promising emerging real-time data capture technology that is currently available to manufacturers.Having analyzed the features and shortcomings of the individual systems perse,and by considering the advantages that may be realized through effective integration of these otherwise discrete systems,we propose a framework for real-time PPC. | Emrah Arica Daryl J.Powell | 2014 | Advances in Manufacturing2014，2，2： | 2 |
| 17 | Ectopic liver tissue (choristoma) on the gallbladder: Acomprehensive literature review显示文摘BACKGROUND Liver tissue situated outside the liver with a hepatic connection is usually calledan accessory liver, and that without a connection to the mother liver, is calledectopic liver tissue.AIM To identify studies in the literature on ectopic liver tissue located on thegallbladder surface or mesentery.METHODS We present two patients and review published articles on ectopic liver tissuelocated on the gallbladder surface accessed via PubMed, MEDLINE, GoogleScholar, and Google databases. Keywords used included accessory liver lobe,aberrant liver tissue, ectopic liver tissue, ectopic liver nodule, heterotopic livertissue, hepatic choristoma, heterotopic liver tissue on the gallbladder, and ectopicliver tissue on the gallbladder. The search included articles published before June2020 with no language restriction. Letters to the editor, case reports, reviewarticles, original articles, and meeting presentations were included in the search.Articles or abstracts containing adequate information on age, sex, history of liverdisease, preliminary diagnosis, radiologic tools, lesion size, surgical indication,surgical procedure, and histopathological features of ectopic liver tissue wereincluded in the study.RESULTS A total of 72 articles involving 91 cases of ectopic liver tissue located on the gallbladder surface or mesentery were analyzed. Of these 91 patients, 62 werefemale and 25 were male (no gender available for 4 patients), and the age rangewas 5 d to 91 years. Forty-nine patients underwent surgery for chroniccholecystitis or cholelithiasis, and 14 patients underwent surgery for acutecholecystitis. The remaining 28 patients underwent laparotomy for other reasons.Cholecystectomy was laparoscopic in 69 patients and open in 11 patients. Theremaining 19 patients underwent various other surgical procedures such asautopsy, liver transplantation, living donor hepatectomy, Whipple procedure, andliver segment V resection. Histopathologically, hepatocellular carcinoma wasdetected in the ectopic liver tissue of one patient.CONCLUSION Ectopic liver tissue is a rare developmental anomaly which is usually detectedincidentally. Although most studies suggest that ectopic liver located outside thegallbladder has a high risk of hepatocellular carcinoma, this is not reflected instatistical analysis. | Sami Akbulut Khaled Demyati Felat Ciftci Cemalettin Koc Adem Tuncer Emrah Sahin Nese Karadag Sezai Yilmaz | 2020 | World Journal of Gastrointestinal Surgery2020，12，12： | 2 |

| 20 | Comparison of the clinical efficacy of two different types of post systems which were restored with composite restorations显示文摘AIM To compare the efficacy of resin composite restorations, retained with either polyethylene or zirconia-rich glass fiber posts. METHODS Sixty-two single rooted maxillary and mandibularcentral incisor teeth in forty-four patients (15 males and 29 females; age range 15-32 years) were restored either with an ultrahigh molecular weight polyethylene(UHMWP) fiber post (Bondable Reinforcement Ribbon, DENSE, Ribbond, Seattle, WA, United States) or a zircon-rich glass fiber post (Snowpost, Lot H 040; Carbotech, Ganges, France). Then, direct resin composite restoration (Clearfil AP-X, Kuraray) was performed for both post systems in tooth color suitable. Patients were recalled for routine inspections at 6 mo, 1, 2 and 3 years.RESULTS The restorations were assessed during each recall evaluation according to predetermined clinical and radiographic criteria (periapical lesion; marginal leakage and integrity; color stability; surface stain and loss of retention of the post or the composite buildup material). The follow-up data showed no significant difference in these criteria between polyethylene fibre posts and zirconia-rich glass fibre posts.CONCLUSION The efficacy of resin composite restorations, retained with either polyethylene or zirconia-rich glass fiber posts were similar, suggesting that both types of fiber post can be used successfully to help retain resin composite restorations. | Buket Ayna Emrah Ayna Sema Celenk Emine Goncü Bacaran Berivan Dündar Yιlmaz Ìbrahim Halil Tacir Mehmet Cudi Tuncer | 2018 | World Journal of Clinical Cases2018，6，3： | 1 |
