| 1 | Current status of diagnosis and treatment of hepatic echinococcosis显示文摘Echinococcus granulosus(E.granulosus) and Echinococcus multilocularis(E.multilocularis) infections are the most common parasitic diseases that affect the liver.The disease course is typically slow and the patients tend to remain asymptomatic for many years.Often the diagnosis is incidental.Right upper quadrant abdominal pain,hepatitis,cholangitis,and anaphylaxis due to dissemination of the cyst are the main presenting symptoms.Ultrasonography is important in diagnosis.The World Health Organization classification,based on ultrasonographic findings,is used for staging of the disease and treatment selection.In addition to the imaging methods,immunological investigations are used to support the diagnosis.The available treatment options for E.granulosus infection include open surgery,percutaneous interventions,and pharmacotherapy.Aggressive surgery is the first-choice treatment for E.multilocularis infection,while pharmacotherapy is used as an adjunct to surgery.Due to a paucity of clinical studies,empirical evidence on the treatment of E.granulosus and E.multilocularis infections is largely lacking;there are no prominent and widely accepted clinical algorithms yet.In this article,we review the diagnosis and treatment of E.granulosus and E.multilocularis infections in the light of recent evidence. | Memmet Mihmanli Ufuk Oguz Idiz Cemal Kaya Uygar Demir Ozgur Bostanci Sinan Omeroglu Emre Bozkurt | 2016 | World Journal of Hepatology2016，8，28： | 50 |
| 2 | Evolving role of the endoscopist in management of gastrointestinal neuroendocrine tumors显示文摘Neuroendocrine tumors(NETs) are uncommon gastrointestinal neoplasms but have been increasingly recognized over the past few decades. Luminal NETs originate from the submucosa of the gastrointestinal tract and careful endoscopic exam is a key for accurate diagnosis. Despite their reputation as indolent tumors with a good prognosis,some NETs may have aggressive features with associated poor long-term survival. Management of NETs requires full understanding of tumor size,depth of invasion,local lymphadenopathy status,and location within the gastrointestinal tract. Staging with endoscopic ultrasound or cross-sectional imaging is important for determining whether endoscopic treatment is feasible. In general,small superficial NETs can be managed by endoscopic mucosal resection and endoscopic submucosal dissection(ESD). In contrast,NETs larger than 2 cm are almost universally treated with surgical resection with lymphadenectomy. For those tumors between 11-20 mm in size,careful evaluation can identify which NETs may be managed with endoscopic resection. The increasing adoption of ESD may improve the results of endoscopic resection for luminal NETs. However,enthusiasm for endoscopic resection must be tempered with respect for the more definitive curative results afforded by surgical treatment with more advanced lesions. | Cemal Yazici Brian R Boulay | 2017 | World Journal of Gastroenterology2017，23，27： | 9 |
| 3 | Diagnosis and treatment of gallbladder perforation显示文摘AIM: To present our clinical experience with gallbladder perforation cases. METHODS: Records of 332 patients who received medical and/or surgical treatment with the diagnosis of acute cholecystitis in our clinic between 1997 and 2006 were reviewed retrospectively. Sixteen (4.8%) of those patients had gallbladder perforation. The parameters including age, gender, time from the onset of symptoms to the time of surgery, diagnostic procedures, surgical treatment, morbidity, and mortality were evaluated. RESULTS: Seven patients had typeⅠgallbladder perforation, 7 type Ⅱ gallbladder perforation, and 2 type Ⅲ gallbladder perforation according to Niemeier’ s classification. The patients underwent surgery after administration of intravenous electrolyte solutions, and were treated with analgesics and antibiotics within the first 36 h (mean 9 h) after admission. Two patients died of sepsis and multiple organ failure in the early postoperative period. Subhepatic abscess, pelvic abscess, pneumonia, pancreatitis, and acute renal failure were found in 6 patients. CONCLUSION: Early diagnosis and emergency surgical treatment of gallbladder perforation are of crucial importance. Upper abdominal computerized tomography for acute cholecystitis patients may contribute to the preoperative diagnosis of gallbladder perforation. | Hayrullah Derici Cemal Kara Ali Dogan Bozdag Okay Nazli Tugrul Tansug Esra Akca | 2006 | World Journal of Gastroenterology2006，12，48： | 9 |
| 4 | Pegylated interferon-alpha plus taurine in treatment of rat liver fibrosis显示文摘AIM: To investigate the antif ibrotic effects of peginterferon- alpha 2b and taurine on oxidative stress markers and hepatocellular apoptosis. METHODS: Sixty rats with CCl4-induced liver fibrosis were divided into 4 groups (n = 15). Group 1 was left for spontaneous recovery (SR). Groups 2-4 received peginterferon-alpha 2b, taurine, and their combination, respectively, for four weeks. Histological f ibrosis scores, histomorphometric analysis, tissue hydroxyproline, tissue MDA, GPx and SOD activities were determined. Activated stellate cells and hepatocellular apoptosis were also evaluated. RESULTS: The degree of f ibrosis decreased in all treatment groups compared to spontaneous recovery group. Taurine alone and in combination with peginterferon-alpha 2b reduced oxidative stress markers, but peginterferon-alpha 2b alone did not. Apoptotic hepatocytes and activated stellate cells were higher in groups 2-4 than in group 1. Combined taurine and peginterferon-alpha 2b further reduced fibrosis and increased activated stellate cell apoptosis, but could not improve oxidative stress more than taurine alone.CONCLUSION: Peginterferon-alpha 2b exerts anti- f ibrotic effects on rat liver fibrosis. It seems ineffective against oxidative stress in vivo. Peginterferon-alpha 2b in combination with taurine seems to be an antif ibrotic strategy. | Ilker Tasci Mehmet Refik Mas Sevil Atalay Vural Salih Deveci Bilgin Comert Gunay Alcigir Nuket Mas Cemal Akay Mithat Bozdayi Cihan Yurdaydin Hakan Bozkaya Ozden Uzunalimoglu Ahmet Turan Isik Harun M Said | 2007 | World Journal of Gastroenterology2007，13，23： | 7 |
| 5 | Comparative evaluation of different statistical tools for the prediction of uniaxial compressive strength of rocks显示文摘In this study,uniaxial compressive strength(UCS),unit weight(UW),Brazilian tensile strength(BTS),Schmidt hardness(SHH),Shore hardness(SSH),point load index(Is50)and P-wave velocity(Vp)properties were determined.To predict the UCS,simple regression(SRA),multiple regression(MRA),artificial neural network(ANN),adaptive neuro-fuzzy inference system(ANFIS)and genetic expression programming(GEP)have been utilized.The obtained UCS values were compared with the actual UCS values with the help of various graphs.Datasets were modeled using different methods and compared with each other.In the study where the performance indice PIat was used to determine the best performing method,MRA method is the most successful method with a small difference.It is concluded that the mean PIat equal to 2.46 for testing dataset suggests the superiority of the MRA,while these values are 2.44,2.33,and 2.22 for GEP,ANFIS,and ANN techniques,respectively.The results pointed out that the MRA can be used for predicting UCS of rocks with higher capacity in comparison with others.According to the performance index assessment,the weakest model among the nine model is P7,while the most successful models are P2,P9,and P8,respectively. | Ahmet Teymen Engin Cemal Mengüç | 2020 | International Journal of Mining Science and Technology2020，30，6： | 7 |
| 6 | Inpatient capsule endoscopy leads to frequent incomplete small bowel examinations显示文摘AIM:To examine the predictive factors of capsule endoscopy(CE) completion rate(CECR) including the effect of inpatient and outpatient status.METHODS:We identified 355 consecutive patients who completed CE at Rush University Medical Center between March 2003 and October 2005.Subjects for CE had either nothing by mouth or clear liquids for the afternoon and evening of the day before the procedure.CE exams were reviewed by two physicians who were unaware of the study hypotheses.After retrospective analysis,21 cases were excluded due to capsule malfunction,prior gastric surgery,endoscopic capsule placement or insufficient data.Of the remaining 334 exams [264 out-patient(OP),70 in-patient(IP)],CE indications,findings,location of the patients [IP vs OP and intensive care unit(ICU) vs general medical floor(GMF)] and gastrointestinal transit times were analyzed.Statistical analysis was completed using SPSS version 17(Chicago,IL).Chi-square,t test or fisher exact-tests were used as appropriate.Multivariate logistic regression analysis was used to identify variables associated with incomplete CE exams.RESULTS:The mean age for the entire study population was 54.7 years.Sixty-one percent of the study population was female,and gender was not different between IPs vs OPs(P = 0.07).The overall incomplete CECR was 14% in our study.Overt obscure gastrointestinal bleeding(OGB) was a significantly more common indication for the IP CE(P = 0.0001),while abdominal pain and assessment of IBD were more frequent indications for the OP CE exams(P = 0.002 and P = 0.01,respectively).Occult OGB was the most common indication and arteriovenous malformations were the most common finding both in the IPs and OPs.The capsule did not enter the small bowel(SB) in 6/70 IPs and 8/264 OPs(P = 0.04).The capsule never reached the cecum in 31.4%(22/70) of IP vs 9.5%(25/264) of OP examinations(P < 0.001).The mean gastric transit time(GTT) was delayed in IPs compared to OPs,98.5 ± 139.5 min vs 60.4 ± 92.6 min(P = 0.008).Minimal SB transit time was significantly prolonged in the IP compared to the OP setting [IP = 275.1 ±111.6 min vs OP = 244.0 ± 104.3 min(P = 0.037)].CECR was also significantly higher in the subgroup of patients with OGB who had OP vs IP exams(95% vs 80% respectively,P = 0.001).The proportion of patients with incomplete exams was higher in the ICU(n = 7/13,54%) as compared to the GMF(n = 15/57,26%)(P = 0.05).There was only a single permanent SB retention case which was secondary to a previously unknown SB stricture,and the remaining incomplete SB exams were due to slow transit.Medications which affect gastrointestinal system motility were tested both individually and also in aggregate in univariate analysis in hospitalized patients(ICU and GMF) and were not predictive of incomplete capsule passage(P > 0.05).Patient location(IP vs OP) and GTT were independent predictors of incomplete CE exams(P < 0.001 and P = 0.008,respectively).CONCLUSION:Incomplete CE is a multifactorial problem.Patient location and related factors such as severity of illness and sedentary status may contribute to incomplete exams. | Cemal Yazici John Losurdo Michael D Brown Scott Oosterveen Robert Rahimi Ali Keshavarzian Leila Bozorgnia Ece Mutlu | 2012 | World Journal of Gastroenterology2012，18，36： | 6 |

| 8 | Automatic fuzzy-DBSCAN algorithm for morphological and overlapping datasets显示文摘Clustering is one of the unsupervised learning problems.It is a procedure which partitions data objects into groups.Many algorithms could not overcome the problems of morphology,overlapping and the large number of clusters at the same time.Many scientific communities have used the clustering algorithm from the perspective of density,which is one of the best methods in clustering.This study proposes a density-based spatial clustering of applications with noise(DBSCAN)algorithm based on the selected high-density areas by automatic fuzzy-DBSCAN(AFD)which works with the initialization of two parameters.AFD,by using fuzzy and DBSCAN features,is modeled by the selection of high-density areas and generates two parameters for merging and separating automatically.The two generated parameters provide a state of sub-cluster rules in the Cartesian coordinate system for the dataset.The model overcomes the problems of clustering such as morphology,overlapping,and the number of clusters in a dataset simultaneously.In the experiments,all algorithms are performed on eight data sets with 30 times of running.Three of them are related to overlapping real datasets and the rest are morphologic and synthetic datasets.It is demonstrated that the AFD algorithm outperforms other recently developed clustering algorithms. | YELGHI Aref KÖSE Cemal YELGHI Asef SHAHKAR Amir | 2020 | Journal of Systems Engineering and Electronics2020，31，6： | 5 |
| 9 | Success rates for various graft materials in tympanoplasty e A review显示文摘Objectives:The aim of this paper is to review how successful each type of grafts is in tympanoplasty.Methods:Pubmed,Google and the Proquest Central Database at Kırıkkale University were queried using the keywords“graft”,“success”“tympanoplasty”,“success rate”with the search limited to the period 1955 to 2017.Results:Various types of graft materials including temporalis fascia,cartilage,perichondrium,periosteum,vein,fat or skin have been used in the reconstruction of tympanic membrane(TM)perforation.Although temporalis fascia ensures good hearing is restored,there are significant concerns that its dimensional stability characteristics may lead to residual perforation,especially where large TM perforations are involved.The“palisade cartilage”and“cartilage island”techniques have been stated to increase the strength and stability of a tympanic graft,but they may result in a less functional outcome in terms of restoring hearing.Smoking habits,the size and site of a perforation,the expertise level of the operating surgeon,age,gender,the status of the middle ear mucosa and the presence of myringosclerosis or tympanosclerosis are all important in determining how successful a graft is.Conclusion:Although temporal fascia is the most commonly used graft material for tympanoplasty,poor graft stability may cause failure.This failure is due to the inclusion of connective fibrous tissue containing irregular elastic fibers present in the grafted fascia.Cartilage grafts offer better ability to resist infection,pressure,and cope with insufficient vascular supply.This means that cartilage grafts are suitable for use in revision cases. | Ali Bayram Nuray Bayar Muluk Cemal Cingi Sameer Ali Bafaqeeh | 2020 | Journal of Otology2020，15，3： | 4 |

| 11 | Nasobronchial interaction显示文摘Upper and lower airways can be considered as a unifiedmorphofunctional unit. In this paper, nasobronchial interactions are evaluated based on literature.To discuss nasobronchial interactions, literature review from Pub Med since 1982 is evaluated. Data base was including the terms 'nasobronchial interaction, nasal and bronchial'. Asthma and rhinosinusitis may be associated with environmental factors and immunological predisposition. Treatment of rhinosinusitis may decrease asthma exacerbations. It was concluded that 'one airway, one disease'-concept may be accepted when considering naso-bronchial interaction. Asthma treatment should also mean treating the nose as good as treating patients with nasal symptoms. To reach the succesful results it should be associated with evaluation of lung functions. | Cemal Cingi Nuray Bayar Muluk Bengu Cobanoglu Tolgahan ?atli O?uzhan Dikici | 2015 | World Journal of Clinical Cases2015，3，6： | 3 |
| 12 | 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 |
| 13 | A Computational Investigation of the Thermohydraulics of an EGS Project显示文摘A numerical analysis of the thermohydraulics of an enhanced geothermal system project is presented. The rock structures are modelled as porous medium, based on the computationally obtained hydraulic fracturing data of other authors. The influence of the domain size, grid resolution, temporal resolution and the discretization scheme is assessed to obtain a highly accurate numerical solution under the prevailing modelling assumptions. Based on the numerical model, different production scenarios are investigated and discussed. The relative positioning of the injection and production ports is also analyzed. It is shown that there is a considerable potential for optimizing the production rate and the port configuration to obtain the most favorable results for the production temperature, investment costs and operation costs. | BENIM Ali Cemal CICEK Aydin EKER Arif Mert | 2018 | Journal of Thermal Science2018，27，5： | 2 |

| 20 | Geochemistry and Zircon U-Pb Dates of Felsic-Intermediate Members of the Late Cretaceous Yüksekova Arc Basin: Constraints on the Evolution of the Bitlis–Zagros Branch of Neotethys(Elazig, E Turkey)显示文摘During the Late Cretaceous in the Eastern Mediterranean, the northern branch of the southern Neotethys was closed by multiple northward subductions. Of these, the most northerly located subduction created the Baskil continental arc at around 82–84 Ma. The more southerly and intra-oceanic subduction, on the other hand, produced an arc-basin system,the Yüksekova Complex, as early as the late Cenomanian–early Turonian. The abundant and relatively well-studied basaltic rocks of this complex were intruded by dykes, sills and small stocks of felsic–intermediate rocks, not previously studied in detail. The intrusives collected from five different localities in the Elazig region of eastern Turkey are all subalkaline, with low Nb/Y values. Most of them have been chemically classified as rhyodacites/dacites, whereas a small number appear to be andesites. In normal mid-ocean-ridge basalt(N-MORB)-normalised plots, the intrusives are characterised by relative enrichments in Th and La over Nb, Zr, Hf, Ti and high field strength elements(HREEs), indicating their derivation from a subduction-modified source. While their relatively high, positive εN d(i) values(+6.4 and +7.2) might suggest a depleted mantle source for their ultimate origin, somewhat radiogenic Pb values indicate a sedimentary contribution to the source of the rocks. The overall geochemical characteristics indicate their generation in an oceanic arc setting. The zircon U-Pb Laser ablation-inductively coupled plasma-mass spectrometry(LA-ICP-MS) data obtained from five felsic-intermediate rock samples yielded intrusion dates of 80–88 Ma. This suggests that the Elazig oceanic arc-related intrusives are slightly younger than those of the Yüksekova arc-basin system, but coeval with the Baskil continental arc. However, the felsic–intermediate intrusives show different geochemical characteristics(oceanic arc-type, with a lack of crustal contamination)to those of the Baskil continental arc. This indicates that these two igneous systems are unrelated and likely developed in different tectonic settings. This, in turn, supports a geodynamic model in which the northern strand of the southern Neotethys was consumed by multiple northward subductions. | Melek URAL Kaan SAYIT Osman Ersin KORALAY Mehmet Cemal GONCUOGLU | 2021 | Acta Geologica Sinica(English Edition)2021，95，4： | 1 |
