1Hepatitis E virus: Epidemiology, diagnosis, clinical manifestations, and treatment显示文摘The hepatitis E virus(HEV)is the fifth known form of viral hepatitis and was first recognized as the cause of an epidemic of unexplained acute hepatitis in the early 1980s.Globally,it is one of the most frequent causes of acute viral hepatitis.The majority of HEV infections are asymptomatic and lead to the spontaneous clearance of the virus.Among the eight different genotypes identified to date,HEV genotype 1(HEV1),HEV2,HEV3,and HEV4 are the most frequent genotypes causing infections in humans.HEV1 and HEV2 are prevalent in developing regions and able to result in large-scale outbreaks originating from contaminated water supplies.They are also responsible for severe hepatitis in pregnant patients and infants.In contrast,HEV3 and HEV4 are zoonotic,and the transmission of these genotypes to humans occurs mainly through the fecal contamination of water and consumption of contaminated meat from infected animals.Their main reservoir is the pig,and they are mostly encountered in developed countries.The major risk groups for HEV infection and its ensuing adverse consequences are pregnant women,infants,older people,immunocompromised individuals,patients with underlying chronic liver diseases,and workers that come into close contact with HEV-infected animals.In the clinical perspective,HEV infections have diverse clinical manifestations including acute and self-limiting hepatitis,acute-on-chronic liver disease,chronic hepatitis,cirrhosis,and liver failure.Although HEV mainly results in acute selflimiting infection,chronic HEV infection may occur among immunocompromised patients(e.g.,solid-organ transplant recipients).Additionally,HEV-associated extrahepatic manifestations involving various organs have been reported in the last decade,although the causal link for many of them still needs to be proven.Ribavirin and interferon-alpha are the most widely used agents for the treatment of HEV infections with a certain level of success.However,ribavirin is contraindicated in pregnant patients,and interferon-alpha cannot be used in most transplant recipients.Therefore,there is an urgent need for novel antiviral compounds that are safe and effective particularly for patients having contraindications for ribavirin or interferon-alpha and infected by the ribavirinresistant HEV.In this review article,a literature search using PubMed and MEDLINE databases was performed,up to March 2020.Only the articles published in English were reviewed.Abdullah Tarık Aslan Hatice Yasemin Balaban 2020World Journal of Gastroenterology2020,26,37:15
2Insulin resistance in H pylori infection and its association with oxidative stress显示文摘AIM: To determine the insulin resistance (IR) and oxidative status in H pylori infection and to find out if there is any relationship between these parameters and insulin resistance. METHODS: Fifty-five H pylori positive and 48 H pylori negative patients were enrolled. The homeostasis model assessment (HOMA) was used to assess insulin resistance. Serum total antioxidant capacity (TAC), total oxidant status (TOS) and oxidative stress index (OSI) were determined in all subjects. RESULTS: The total antioxidant capacity was significantly lower in H pylori positive group than in H pylori negative group (1.36 ± 0.33 and 1.70 ± 0.50, respectively; P < 0.001), while the total oxidant status and oxidative stress index were significantly higher in H pylori positive group than in H pylori negative group (6.79 ± 3.40 and 5.08 ± 0.95, and 5.42 ± 3.40 and 3.10 ± 0.92, respectively; P < 0.001). Insulin resistance was significantly higher in H pylori positive group than in H pylori negative group (6.92 ± 3.86 and 3.61 ± 1.67, res- pectively; P < 0.001). Insulin resistance was found to be significantly correlated with total antioxidant capacity (r = -0.251, P < 0.05), total oxidant status (r = 0.365, P < 0.05), and oxidative stress index (r = 0.267, P < 0.05). CONCLUSION: Insulin resistance seems to be associated with increased oxidative stress in H pylori infection. Further studies are needed to clarify the mechanisms underlying this association and elucidate the effectof adding antioxidant vitamins to H pylori eradication therapy on insulin resistance during H pylori infection.Mehmet Aslan Mehmet Horoz Yasar Nazligul Cengiz Bolukbas F Fusun Bolukbas Sahbettin Selek Hakim Celik Ozcan Erel 2006World Journal of Gastroenterology2006,12,42:15
3Emergency 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 2013World Journal of Gastroenterology2013,19,38:11
4Supercritical CO_2: Properties and Technological Applications-A Review显示文摘The main goal of the present paper is to assess the available information so as to obtain a general procedure for dealing with the critical enhancement of the thermodynamic and transport properties of supercritical CO_2 and CO_2 containing binary mixtures for practical and scientific applications. The present review provides comprehensive analysis of the thermodynamic and transport properties of supercritical carbon dioxide and CO_2 containing binary mixtures(experiment and theory) and their various technological and scientific applications in different natural and industrial processes. The available information for the thermodynamic and transport properties(experiment and theory) enhancement(anomaly) of supercritical carbon dioxide and SC CO_2 + solute mixtures is comprehensively reviewed. The effect of long-range order parameter fluctuations on the thermodynamic and transport properties of supercritical fluids(SC CO_2) will be discussed. Simplified scaling type equation based on mode-coupling theory of critical dynamics with two critical amplitudes and one cutoff wave number as fluid-specific parameters was used to accurately predict of the transport properties of supercritical carbon dioxide. The recommended values of the specific parameters(asymptotic critical amplitudes) of the carbon dioxide for practical(prediction of the thermodynamic and transport properties of the supercritical CO_2 for technological applications) and scientific use were provided. The role of the critical line shapes of the carbon dioxide containing binary mixture(SC CO_2+solvent) in determination of the critical behavior of the mixture near the critical point of pure supercritical solvent(CO_2) is discussed. Krichevskii parameter concept for a description of thermodynamic behavior of dilute near-critical SC CO_2+solute mixtures is also discussed. The structural and thermodynamic properties of the carbon dioxide containing binary mixtures near the critical point of pure solvent(CO_2) are discussed.NIKOLAI Polikhronidi RABIYAT Batyrova ASLAN Aliev ILMUTDIN Abdulagatov 2019Journal of Thermal Science2019,28,3:10
5Effects of grain size on phase transition behavior of nanocrystalline shape memory alloys显示文摘We report recent advances in the experimental and theoretical study of grain size(GS)effects on the thermal and mechanical properties of nanostructured NiTi polycrystalline shape memory alloy(SMA).It is shown that when GS<60 nm,the superelastic stress-strain hysteresis loop area(H)of the polycrystal decreases rapidly with GS and tends to vanish as GS approaches 10 nanometers.At the same time,the temperature dependence of the transition stress also decreases with GS and eventually approaches zero,leading to a wide superelastic temperature window and breakdown of the Clausius-Claperyon relationship.Rate dependence of the stress-strain responses is significantly reduced and the cyclic stability of the material is improved by the nanocrystallization.It is proposed that the emergence of such significant changes in the behavior of the material with GS reduction originate from the large increase in the area-to-volume ratios of the nanometer-thick interfaces(grain boundary and Austenite-Martensite(A-M)interface)in the polycrystal.In particular,with GS reduction,interfacial energy terms will gradually become dominant over the bulk energy of the crystallite,eventually bring fundamental changes in the phase transition responses of the material.Modelling strategy leading to the establishment of quantitative relationships among GS,grain boundary,A-M interfaces and the macroscopic responses of the material are outlined.SUN QingPing ASLAN Ahadi LI MingPeng CHEN MingXiang 2014Science China(Technological Sciences)2014,57,4:9
6Is increased red cell distribution width an indicating marker of nonalcoholic steatohepatitis and fibrotic stage?显示文摘AIM:To evaluate the red cell distribution width(RDW)as an indicator of the presence of non-alcoholic steatohepatitis(NASH)and its association with fibrotic scores.METHODS:A retrospective study was carried out that included sixty-two biopsy proven NASH,32 simple steatosis patients and 30 healthy controls.The correlation between the clinical and histopathological features of NASH patients and RDW values was evaluated.Liver fibrosis scores were measured using a 0 to 4 point scale and were divided in to two groups;fibrosis scores0-1 were termed mild and fibrosis scores 2-4 were termed advanced fibrosis.RDW values were compared between NASH,simple steatosis and healthy controls.Univariate and multivariate analyses were performed to evaluate the independent predicting factors for the presence of liver fibrosis caused by NASH.RESULTS:Patients with NASH had higher RDW values compared with simple steatosis and healthy control groups[14.28%±0.25%vs 13.37%±0.12%,12.96%±0.14%(P<0.01),respectively].Patients with advanced fibrosis had higher RDW values than the mild fibrosis group(15.86%±0.4%vs 13.63%±0.67%,P<0.01,respectively).RDW also correlated with fibrotic scores(r=0.579 andP<0.01).The variables that were significant in the univariate analysis were evaluated in multivariate logistic regression analysis,and RDW was an independent predicting factor of NASH(OR=1.75,95%CI:1.129-2.711,P<0.05).CONCLUSION:RDW a new non-invasive marker that can be used to demonstrate the presence of NASH and indicate advanced fibrotic scores.Mustafa Cengiz Burcu Aslan Candir Güldal Yilmaz Gülen Akyol Seren Ozenirler 2013World Journal of Gastroenterology2013,19,42:8
7Comparison of central corneal thickness measurements with three new optical devices and a standard ultrasonic pachymeter显示文摘AIM:To compare the RTVue spectral optical coherence tomography(SD-OCT),Sirius Scheimpflug-Placido topographer,Lenstar optical low coherence reflectometry(OLCR)and ultrasound pachymetry(USP)devices in terms of their agreement and repeatability of measuring central corneal thickness(CCT).METHODS:In this prospective study,50 eyes of 50patients were included.Three repeated measures were obtained using SD-OCT,Scheimpflug-Placido topographer and USP and five measurements were determined with the OLCR.Bland-Altman plots were used to assess agreement among the instruments,and 95%limits of agreement(LoA)for each comparison were calculated.Intra-examiner repeatability was assessed using intraclass correlation coefficients(ICCs).RESULTS:The mean CCT by SD-OCT,ScheimpflugPlacido topographer,OLCR,and USP were 525.90±34.08μm,525.92±34.10μm,530.30±35.62μm,and543.50±37.11μm respectively.All 4 modalities of CCT measurements correlated closely with each other,with Pearson correlation coefficients ranging from 0.977 to0.995.The mean differences(and upper/lower LoA)for CCT measurements were-0.05±6.77μm(13.3/-13.3)between SD-OCT and Scheimpflug-Placido topographer,4.38±3.79μm(11.8/-3.1)between OLCR and SD-OCT,4.38±6.03μm(16.2/-7.5)between OLCR and ScheimpflugPlacido topographer,13.20±6.46μm(25.9/0.5)between USP and OLCR,17.59±6.76μm(30.8/4.3)between USP and SD-OCT,and 17.58±8.13μm(33.5/1.6)between USP and Scheimpflug-Placido topographer.Intra-examiner repeatability was excellent for all devices with ICCs>0.98.CONCLUSION:For most practical purposes,CCT measurements with the RTVue,Sirius and Lenstar can be used interchangeably.Although highly correlated,CCTmeasurement differences between USP and these 3optical instruments can be significant depending on the clinical situation.Hasan Ali Bayhan Seray Aslan Bayhan Iz.zet Can 2014International Journal of Ophthalmology(English edition)2014,7,2:8
8成品革中重金属含量的研究显示文摘对多种皮革制品中重金属的含量进行了研究。涉及的重金属均具有较强的毒性,成为很多皮革制品中的禁用品,如钴、铬、铜、锌、铅和镍。对与人体接触较多的内底革、鞋面革和服装革中的重金属含量进行了研究。结果表明:成品革中的重金属含量与加工过程中所使用的化工材料有直接关系,革样中的铬含量较高,此外,还含有少量的镉、锌、铅、钴和铜,这主要是由革在染色和涂饰过程中发生的一系列物理和化学反应造成的。最后,把革样中检测出来的重金属含量与皮革和纺织品中的规定含量进行了比较。B BASARAN M ISCAN B O BITLISLI A ASLAN 周富春 郭灏 刘鹏杰 2007中国皮革2007,36,19:5

11Effect of Microstructure on Exhaust Manifold Cracks Produced From SiMo Ductile Iron显示文摘Ductile cast irons are used as high temperature materials in internal combustion engines,because they are microstructurally stable at high operating temperatures. SiMo granular graphite cast irons contain Fe2MoC and M6C carbide precipitates due to their higher concentration of both silicon and molybdenum. The microstructure of these cast irons consists of carbides dispersed within the ferrite matrix. The microstructural change and the crack formation mechanism in manifolds produced from SiMo ductile iron are studied. Chemical analysis,optical and scanning electron microscope studies have been completed and evaluated.Havva Kazdal Zeytin Ceylan Kubilay Hseyin Aydin Ali Aslan Ebrinc Bilal Aydemir 2009Journal of Iron and Steel Research(International)2009,16,3:3
12Differences in parents of pediatric liver transplantation and chronic liver disease patients显示文摘BACKGROUND With advancements in the treatment of chronic liver disease(CLD),including liver transplantation(LT),quality of life and satisfaction after LT have become an important issue for pediatric patients and their parents.More evidence-based information is needed to describe and assess the impact of pediatric CLD on parents and the satisfaction of parents with treatment to better understand their needs.AIM To assess the satisfaction of parents of pediatric LT patients and that of parents of pediatric CLD patients METHODS During this survey,data were collected from parents of pediatric patients who underwent LT between January 2010 and April 2017(LT group;n=91)and parents of pediatric patients with chronic liver disease(CLD group;n=94).Group comparisons were made based on the pediatric health-related quality of life(PedsQL)health care parent satisfaction scale,impact on family scale(IFS)and demographic characteristics.The PedsQL was administered to parents during a phone interview and the results were used to assess the health carerelated satisfaction of parents.The IFS was used to assess the impact of the child’s CLD status on the family.Demographic variables such as education level(elementary vs middle vs high vs university),monthly income(low vs middle vs high),and place of residence(village vs town vs city)were compared between CLD and LT parent groups.Finally,PedsQL and IFS results were also analyzed according to demographic variables.RESULTS A total of 185 parents aged 19 to 65 years were included.There were statistically significant differences between the LT and CLD groups in terms of career(P<0.001),monthly income(P=0.016),and education level(P=0.041).According to the PedsQL results,family inclusion,communication,technical skills,emotional needs,and overall satisfaction were significantly different between the groups;the LT group had consistently higher scores(P<0.001).Additionally,scores for the IFS parameters of financial impact,familial-social impact,personal strain,and total impact were consistently higher for the LT group(P<0.001).There were statistically significant relationships between education level,monthly income,and place of residence according to the IFS results but not the PedsQL results.There were inverse relationships between the difficulties that parents experience because of their child’s health and education levels,monthly income,and place of residence.However,no relationship was found between education level,monthly income,or place of residence and satisfaction with health care services provided in the hospital according to the PedsQL results.CONCLUSION Parents of children who underwent LT were very satisfied with the health care services provided to their children.However,they had more difficulties than parents of children with CLD.Sami Akbulut Gulsen Gunes Hasan Saritas Bahar Aslan Yunus Karipkiz Khaled Demyati Sukru Gungor Sezai Yilmaz 2020World Journal of Clinical Cases2020,8,11:3
13Analysis of serum antibody profile against H pylori VacA and CagA antigens in Turkish patients with duodenal ulcer显示文摘AIM: To investigate the frequency of seropositivity aga- inst CagA, VacA proteins and to determine their indepen- dent effects on the development of duodenal ulcer (DU) in Turkish patients. METHODS: The study was designed as a prospective one from a tertiary referral hospital. Dyspeptic patients who were referred to our endoscopy unit for upper gas- trointestinal endoscopy between June 2003 and March 2004 and diagnosed to have DU or nonulcer dyspepsia (NUD) were included. Biopsies from the antrum and body of the stomach were taken in order to assess the current H pylori status by histology, rapid urease test and culture. Fasting sera were obtained from all patients and H pylori status of all sera was determined by IgG antibo- dies using an enzyme-linked immunosorbent assay (ELI- SA) kit. All seropositive patients were further analysed using Western blot assays detecting IgG antibodies aga- inst CagA and VacA proteins. The χ2 test was used for statistical comparison of the values and age-sex adjusted multiple regression analysis was used to determine the independent effects of CagA and VacA seropositivities on the development of DU. RESULTS: Sixty-three patients with DU and 62 patients with NUD were eligible for the final analysis. Seropositi- vity for anti-CagA was detected in 51 of 62 (82%), andin 55 of 63 (87%) patients with NUD and DU, respec- tively (p = no significance), and seropositivity for anti- VacA was found in 25 of 62 (40% ) and in 16 of 63 (25%) patients, with NUD and DU, respectively. CONCLUSION: These findings suggest that none of the- se virulence factors is associated with the development of DU in the studied Turkish patients with dyspepsia.Yusuf Erzin Sibel Altun Ahmet Dobrucali Mustafa Aslan Sibel Erdamar Ahmet Dirican Murat Tuncer Bekir Kocazeybek 2006World Journal of Gastroenterology2006,12,42:3
14Isolation 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 2015World Journal of Gastroenterology2015,21,9:2
15Biepicondylar fracture dislocation of the elbow joint concomitant with ulnar nerve injury显示文摘In this article, we present a case of humeral biepicondylar fracture dislocation concomitant with ulnar nerve injury in a seventeen year-old male patient. Physical examination of our patient in the emergency room revealed a painful, edematous and deformed-looking left elbow joint. Hypoesthesia of the little finger was also diagnosed on the left hand. Radiological assessment ended up with a posterior fracture dislocation of the elbow joint accompanied by intra-articular loose bodies. Open reduction-Internal fixation of the fracture dislocation and ulnar nerve exploration were performed under general anesthesia at the same session as surgical treatment of our patient. Physical therapy and rehabilitation protocol was implemented at the end of two weeks post-operatively. Union of the fracture lines, as well as the olecranon osteotomy site, was achieved at the end of four months post-operatively. Ulnar nerve function was fully restored without any sensory or motor loss. Range of motion at the elbow joint was 20-120 degrees at the latest follow-up.M Nuri Konya Ahmet Aslan Hakan Sofu Timur Y?ld?r?m 2013World Journal of Orthopedics2013,4,2:2
16Improvement in renal functions with transcatheter aortic valve implantation显示文摘BACKGROUND & OBJECTIVES:In recent years, emerging transcatheter aortic valve implantation (TAVI) has become an alternative for surgery。 However, with advanced age, several co-morbid factors together with contrast agent usage can cause deterioration in renal function and increase in the risk of acute kidney injury (AKI) with poor prognosis in patients with AKI。 Therefore, many patients cannot benefit from this treatment。 In this study, we aim to examine the effects of TAVI on renal functions。 METHODS AND RESULTS: Seventy patients, mean age of 77.6 years, underwent TAVI between July 2011 and December 2012。 Estimated glomerular filtration rate (eGFR) was calculated by using the Cockcroft and Gault Formula。 Patients were monitored for 48 h for urine output。 Stage 1 AKI, according to the VARC-2 AKIN system, developed in only five (7.1%) of the patients after the procedure。 There was a statistically significant increase between the mean 1(st) month eGFRs before (68。2 vs。 61.0, P < 0.01) and after (68。2 vs。 63.6, P < 0.05) the TAVI in the cohort。 After TAVI (48。5 mL/min, P < 0.01) and the 1(st) month (52.1 mL/min, P < 0.01), the eGFR of the 36 (51.4%) patients diagnosed with chronic kidney disease before the procedure showed a statistically significant increase in renal functions。 The hospital mortality rate was higher in the group which developed AKI (P < 0.01)。 First month eGFR showed a more statistically significant increase than pre-TAVI eGFR (62.8 and 69.8, P < 0.05, respectively) in AKI developing patients and this difference - though statistically not significant - continued into the sixth month。 CONCLUSIONS: In this study, we showed that the treatment of aortic stenosis through TAVI allows improvement of renal functions, and that AKI rates will be lower with careful patient selection, proper pre-procedural hydration, and careful use of contrast agent。Telat Keleş Huseyin Ayhan Durmaz Sarı Aslan AN Erdoğan KE Kasapkara Bilen Bayram Akçay Bozkurt 2013Journal of Geriatric Cardiology2013,10,4:2

19Traveling Wave Solutions for Nonlinear Differential-Difference Equations of Rational Types显示文摘Differential-difference equations are considered to be hybrid systems because the spatial variable n is discrete while the time t is usually kept continuous.Although a considerable amount of research has been carried out in the field of nonlinear differential-difference equations,the majority of the results deal with polynomial types.Limited research has been reported regarding such equations of rational type.In this paper we present an adaptation of the(G /G)-expansion method to solve nonlinear rational differential-difference equations.The procedure is demonstrated using two distinct equations.Our approach allows one to construct three types of exact traveling wave solutions(hyperbolic,trigonometric,and rational) by means of the simplified form of the auxiliary equation method with reduced parameters.Our analysis leads to analytic solutions in terms of topological solitons and singular periodic functions as well.smail Aslan 2016Communications in Theoretical Physics2016,65,1:2
