| 1 | Effect of prophylactic clip placement following endoscopic mucosal resection of large colorectal lesions on delayed polypectomy bleeding: A meta-analysis显示文摘BACKGROUND The role of prophylactic clipping for the prevention of delayed polypectomy bleeding(DPB) remains unclear and conclusions from prior meta-analyses are limited due to the inclusion of variety of resection techniques and polyp sizes.AIM To conduct a meta-analysis on the effect of clipping on DPB following endoscopic mucosal resection(EMR) of colorectal lesions ≥ 20 mm.METHODS We performed a search of PubMed and the Cochrane library for studies comparing the effect of clipping vs no clipping on DPB following endoscopic resection. The Cochran Q test and I^2 were used to test for heterogeneity. Pooling was conducted using a random-effects model.RESULTS Thirteen studies with a total of 7794 polyps were identified, of which data was available on 1701 cases of EMR of lesions ≥ 20 mm. Prophylactic clipping was associated with a lower rate of DPB(1.4%) when compared to no clipping(5.2%)(pooled OR: 0.24, 95%CI: 0.12-0.50, P < 0.001) following EMR of lesions ≥ 20 mm.There was no significant heterogeneity among the studies(I^2 = 0%, P = 0.67).CONLUSION Prophylactic clipping may reduce DPB following EMR of large colorectal lesions.Future trials are needed to further identify risk factors and stratify high risk cases in order to implement a cost-effective preventive strategy. | Fares Ayoub Donevan R Westerveld Justin J Forde Christopher E Forsmark Peter V Draganov Dennis Yang | 2019 | World Journal of Gastroenterology2019，25，18： | 9 |
| 2 | Evaluation of Doppler-ultrasonography in the diagnosis of transjugular intrahepatic portosystemic shunt dysfunction: A prospective study显示文摘AIM To prospectively evaluate the performance of Dopplerultrasonography(US) for the detection of transjugular intrahepatic portosystemic shunt(TIPS) dysfunction within a multicenter cohort of cirrhotic patients.METHODS This study was conducted in 10 french teaching hospitals. After TIPS insertion, angiography and liver Doppler-US were carried out every six months to detect dysfunction(defined by a portosystemic gradient ≥ 12 mm Hg and/or a stent stenosis ≥ 50%). The association between ultrasonographic signs and dysfunction was studied by logistic random-effects models, and the diagnostic performance of each Doppler criterion was estimated by the bootstrap method. This study was approved by the ethics committee of Tours.RESULTS Two hundred and eighteen pairs of examinations performed on 87 cirrhotic patients were analyzed. Variables significantly associated with dysfunction were: The speed of flow in the portal vein(P = 0.008), the reversal of flow in the right(P = 0.038) and left(P = 0.049) portal branch, the loss of modulation of portal flow by the right atrium(P = 0.0005), ascites(P = 0.001) and the overall impression of the operator(P = 0.0001). The diagnostic performances of these variables were low; sensitivity was < 58% and negative predictive value was < 73%. Therefore, dysfunction cannot be ruled out from Doppler-US. CONCLUSION The performance of Doppler-US for the detection of TIPS dysfunction is poor compared to angiography. New tools are needed to improve diagnosis of TIPS dysfunction. | Charlotte Nicolas Amelie Le Gouge Louis d’Alteroche Jean Ayoub Monica Georgescu Vincent Vidal Denis Castaing Jean-Pierre Cercueil Patrick Chevallier Jerome Roumy Herve Trillaud Louis Boyer Vincent Le Pennec Christophe Perret Bruno Giraudeau Jean-Marc Perarnau STIC-TIPS group | 2017 | World Journal of Hepatology2017，9，27： | 6 |

| 4 | 利用井筒稳定性分析确定砂岩安全钻井液密度窗口显示文摘以伊朗西南部某油田Asmari组砂岩储集层为研究对象,研究其中一口垂直井的井筒稳定性,利用FLAC3D软件,根据钻遇地层地质力学特征建立井筒的有限体积模型,监测井壁岩石塑性状态的形成以确定砂岩层安全钻井液密度的上限值和下限值。评估了岩石强度特性、井筒周围主要地应力和孔隙压力对该井安全钻井液密度窗口的影响,敏感性分析结果表明,井壁岩石内聚力和内摩擦角的减小会导致安全钻井液密度窗口大幅变窄;孔隙压力和最大水平应力与最小水平应力之比的减小则会使安全钻井液密度窗口显著增大。此模型便于量化安全钻井液密度窗口的变化,可作为一种油气井钻井方案设计和监测工具。 | DARVISHPOUR Ayoub SEIFABAD Masoud Cheraghi WOOD David Anthony GHORBANI Hamzeh | 2019 | 石油勘探与开发2019，46，5： | 5 |
| 5 | Stability analysis of different cotton genotypes under normal and water-deficit conditions显示文摘Cotton plant observes significant reduction in seed cotton yield when subjected to water stress.To find out genotypes having better drought tolerance,seven genotypes of Gossypium hirsutum L.were tested under two moisture levels,i.e.,normal and water deficit stress conditions at five locations of Punjab,Pakistan(Faisalabad,Sahiwal,Vehari,Rahim Yar Khan,and Bahawalpur)in 2013 and 2014.Genotype×environment interaction(GEI)was studied using the genotype main effects and genotype by environment interaction(GGE)biplot and additive main effect and multiplicative interaction analysis.The genotypes G3(7001/11)and G6(FH-942)were stable under normal condition,while under drought condition,the stable genotype was G5(FH-326)when analysed using additive main effects and multiplicative interaction(AMMI)biplot scheme.While GGE biplot analysis on the basis of best performance revealed that under normal condition the genotypes,G1(L-13/10)and G2(FH-2056/10),carrying the common position in biplot.Whereas,under water deficit stress condition,G5 was the best adaptive genotype at all five locations.In the same way,ranking of genotypes showed that the G5 was the ideal genotype under both conditions.So,it is concluded that the genotype G5(FH-326)was found best for water deficit stress condition and can be cultivated under water scarce areas of Punjab. | Muhammad Riaz Jehanzeb Farooq Saghir Ahmed Muhammad Amin Waqas Shafqat Chattha Maria Ayoub Riaz Ahmed Kainth | 2019 | Journal of Integrative Agriculture2019，18，6： | 5 |
| 6 | Management of refractory ascites in cirrhosis:Are we out of date?显示文摘Cirrhosis is a major cause of morbidity and mortality worldwide with liver transplantations as it only possible cure.In the face of a significant organ shortage many patients die waiting.A major complication of cirrhosis is the development of portal hypertension and ascites.The management of ascites has barely evolved over the last hundred years and includes only a few milestones in our treatment approach,but has overall significantly improved patient morbidity and survival.Our mainstay to ascites management includes changes in diet,diuretics,shunt procedures,and large volume paracentesis.The understanding of the pathophysiology of cirrhosis and portal hypertension has significantly improved in the last couple of decades but the changes in ascites management have not seemed to mirror this newer knowledge.We herein review the history of ascites management and discuss some its current limitations. | Alagappan Annamalai Lauren Wisdom Megan Herada Mazen Nourredin Walid Ayoub Vinay Sundaram Andrew Klein Nicholas Nissen | 2016 | World Journal of Hepatology2016，8，28： | 4 |
| 7 | Effects of dust,soiling,aging,and weather conditions on photovoltaic system performances in a Saharan environment—Case study in Algeria显示文摘Solar photovoltaic(PV)power represents one of the most promising future sources of energy in the world.Considered the cleanest form of energy,extensive research is being undertaken to widen its use.Notably,mega projects are being considered for installation in the Middle East and North Africa(MENA)region because of its high solar potential,with hopes of eventually feeding Europe from the PV electricity generated in this region and transported through high voltage direct current(DC)lines.However,current implementation of PV systems has shown that their reliability and efficiency depend upon surrounding environmental factors,such as the ambient temperature,wind,and rainfall,as well as soiling,pollution,and aging.The aim of this study was to investigate,through experimental tests,the effects of such factors on the power output of a grid connected PV station.The results showed that the output power and efficiency are deeply affected by various environmental factors,which are weather dependent.These findings may help us develop appropriate solutions to overcome these drawbacks. | Meriem Memiche Chaima Bouzian Ayoub Benzahia Ammar Moussi | 2020 | Global Energy Interconnection2020，3，1： | 4 |
| 8 | Effect of transferring lignocellulose-degrading bacteria from termite to rumen fluid of sheep on in vitro gas production, fermentation parameters, microbial populations and enzyme activity显示文摘The digestive tract of termite(Microcerotermes diversus) contains a variety of lignocellulose-degrading bacteria with exocellulases enzyme activity, not found in the rumen, which could potentially improve fiber degradation in the rumen. The objectives of the current study were to determine the effect of inoculation of rumen fluid(RF) with three species of bacteria isolated from termite digestive tract, Bacillus licheniformis, Ochrobactrum intermedium, and Microbacterium paludicola, on in vitro gas production(IVGP), fermentation parameters, nutrient disappearance, microbial populations, and hydrolytic enzyme activities with fibrous wheat straw(WS) and date leaf(DL) as incubation substrate. Inoculation of RF with either of three termite bacteria increased(P<0.05) ammonia-N concentration compared with the control group(free of termite gut bacteria). Termite bacteria inoculation had no effect(P>0.05) on gas production characteristics, dry matter, organic matter and neutral detergent fiber disappearance, pH, and concentration and composition of volatile fatty acids. Population of proteolytic bacteria and protozoa, but not cellulolytic bacteria, were increased(P<0.05) when RF was inoculated with termite bacteria with both WS and DL substrates. Inoculation of RF with termite bacteria increased protease activity, while activities of carboxymethyl-cellulase, microcrystalline-cellulase, α-amylase and filter paper degrading activity remained unchanged(P>0.05). Overall, the results of this study indicated that transferring lignocellulose-degrading bacteria, isolated from digestive tract of termite, to rumen liquid increased protozoa and proteolytic bacteria population and consequently increased protease activity and ammonia-N concentration in vitro, however, no effect on fermentation and fiber degradation parameters were detected. These results suggest that the termite bacteria might be rapidly lysed by the rumen microbes before beneficial effects on the rumen fermentation process could occur. | Ayoub AZIZI Afrooz SHARIFI Hasan FAZAELI Arash AZARFAR Arjan JONKER Ali KIANI | 2020 | Journal of Integrative Agriculture2020，19，5： | 3 |
| 9 | Small for size syndrome difficult dilemma: Lessons from 10 years single centre experience in living donor liver transplantation显示文摘AIM To analyze the incidence, risk factors, prevention, treatment and outcome of small for size syndrome(SFSS) after living donor liver transplantation(LDLT). METHODS Through-out more than 10 years: During the period from April 2003 to the end of 2013, 174 adult-to-adults LDLT(A-ALDLT) had been performed at National Liver Institute, Menoufiya University, Shibin Elkoom, Egypt. We collected the data of those patients to do this cohort study that is a single-institution retrospective analysis of a prospectively collected database analyzing the incidence, risk factors, prevention, treatment and outcome of SFSS in a period started from the end of 2013 to the end of 2015. The median period of follow-up reached 40.50 m, range(0-144 m). RESULTS SFSS was diagnosed in 20(11.5%) of our recipients. While extra-small graft [small for size graft(SFSG)], portal hypertension, steatosis and left lobe graft were significant predictors of SFSS in univariate analysis(P = 0.00, 0.04, 0.03, and 0.00 respectively); graft size was the only independent predictor of SFSS on multivariate analysis(P = 0.03). On the other hand, there was lower incidence of SFSS in patients with SFSG who underwent splenectomy [4/10(40%) SFSS vs 3/7(42.9%) no SFSS] but without statistical significance, However, there was none significant lower incidence of the syndrome in patients with right lobe(RL) graft when drainage of the right anterior and/or posterior liver sectors by middle hepatic vein, V5, V8, and/or right inferior vein was done [4/10(28.6%) SFSS vs 52/152(34.2%) no SFSS]. The 6-mo, 1-, 3-, 5-, 7-and 10-year survival in patients with SFSS were 30%, 30%, 25%, 25%, 25% and 25% respectively, while, the 6-mo, 1-, 3-, 5-, 7-and 10-year survival in patients without SFSS were 70.1%, 65.6%, 61.7%, 61%, 59.7%, and 59.7% respectively, with statistical significant difference(P = 0.00). CONCLUSION SFSG is the independent and main factor for occurrence of SFSS after A-ALDLT leading to poor outcome. However, the management of this catastrophe depends upon its prevention(i.e., selecting graft with proper size, splenectomy to decrease portal venous inflow, and improving hepatic vein outflow by reconstructing large draining veins of the graft). | Hany Shoreem Emad Hamdy Gad Hosam Soliman Osama Hegazy Sherif Saleh Hazem Zakaria Eslam Ayoub Yasmin Kamel Kalid Abouelella Tarek Ibrahim Ibrahim Marawan | 2017 | World Journal of Hepatology2017，9，21： | 3 |
| 10 | A PV powered shunt active power filter for power quality improvement显示文摘This paper deals with power quality improvement using a three-phase active power filter(APF) connected to a PV power system. A direct power control(DPC) approach is proposed to eliminate harmonic current caused by any nonlinear loads and at the same time guarantees the delivery of a part of the load request from the same PV source. A boost converter is used for maximum power point(MPP) tracking purposes under various climate conditions through a fuzzy logic technique. The suggested study is tested under a MATLAB/Simulink environment. The obtained results depict the efficacy of the proposed procedures to meet the IEEE 519-1992 standard recommendation on harmonic levels. | Ayoub Benzahia Rabhi Boualaga Ammar Moussi Laeid Zellouma Memich Meriem Bouziane Chaima | 2019 | Global Energy Interconnection2019，2，2： | 3 |
| 11 | Atypical causes of cholestasis显示文摘Cholestatic liver disease consists of a variety of disorders.Primary sclerosing cholangitis and primary biliary cirrhosis are the most commonly recognized cholestatic liver disease in the adult population,while biliary atresia and Alagille syndrome are commonly recognized in the pediatric population.In infants,the causes are usually congenital or inherited.Even though jaundice is a hallmark of cholestasis,it is not always seen in adult patients with chronic liver disease.Patients can have'silent'progressive cholestatic liver disease for years prior to development of symptoms such as jaundice and pruritus.In this review,we will discuss some of the atypical causes of cholestatic liver disease such as benign recurrent intrahepatic cholestasis,progressive familial intrahepatic cholestasis,Alagille Syndrome,biliary atresia,total parenteral nutrition induced cholestasis and cholestasis secondary to drug induced liver injury. | Ken D Nguyen Vinay Sundaram Walid S Ayoub | 2014 | World Journal of Gastroenterology2014，20，28： | 2 |

| 15 | Posterior lingual lidocaine: A novel method to improve tolerance in upper gastrointestinal endoscopy显示文摘AIM: To evaluate the effect of posterior lingual lidocaine swab on patient tolerance to esophagogastro-duodenoscopy, the ease of performance of the procedure, and to determine if such use will reduce the need for intravenous sedation. METHODS: Eighty patients undergoing diagnostic esophagogastroduodenoscopy in a tertiary care medical center were randomized to either lidocaine swab or spray. Intravenous meperidine and midazolam were given as needed during the procedure. RESULTS: Patients in the lidocaine swab group (SWG) tolerated the procedure better than those in the spray group (SPG) with a median tolerability score of 2 (1, 4) compared to 4 (2, 5) (P < 0.01). The endoscopists encountered less diffi culty performing the proceduresin the SWG with lower median difficulty scores of 1 (1, 5) compared to 4 (1, 5) in the SPG (P < 0.01). In addition, the need for intravenous sedation was also lower in the SWG compared to the SPG with fewer patients requiring intravenous sedation (13/40 patients vs 38/40 patients, respectively, P < 0.01). The patients in the SWG were more satisfi ed with the mode of local anesthesia they received as compared to the SPG. In addition, the endoscopists were happier with the use of lidocaine swab. CONCLUSION: The use of a posterior lingual lidocaine swab in esophagogastroduodenoscopy improves patient comfort and tolerance and endoscopist satisfaction and decreases the need for intravenous sedation. | Assaad M Soweid Shadi R Yaghi Faek R Jamali Abdallah A Kobeissy Michella E Mallat Rola Hussein Chakib M Ayoub | 2011 | World Journal of Gastroenterology2011，17，47： | 2 |
| 16 | AFM-compatible microfluidic platform for affinity- based capture and nanomechanical characterization of circulating tumor cells显示文摘Circulating tumor cells(CTCs)carried by the patient’s bloodstream are known to lead to the metastatic spread of cancer.It is becoming increasingly clear that an understanding of the nanomechanical characteristics of CTCs,such as elasticity and adhesiveness,represents advancements in tracking and monitoring cancer progression and metastasis.In the present work,we describe a combined microfluidic–atomic force microscopy(AFM)platform that uses antibody–antigen capture to routinely isolate and nanomechanically characterize CTCs present in blood samples from prostate cancer patients.We introduce the reversible assembly of a microfluidic device and apply refined and robust chemistry to covalently bond antibodies onto its glass substrate with high density and the desired orientation.As a result,we show that the device can efficiently capture CTCs from patients with localized and metastatic prostate cancer through anti-EpCAM,anti-PSA,and anti-PSMA antibodies,and it is suitable for AFM measurements of captured intact CTCs.When nanomechanically characterized,CTCs originating from metastatic cancer demonstrate decreased elasticity and increased deformability compared to those originating from localized cancer.While the average adhesion of CTCs to the AFM tip surface remained the same in both the groups,there were fewer multiple adhesion events in metastatic CTCs than there were in their counterparts.The developed platform is simple,robust,and reliable and can be useful in the diagnosis and prognosis of prostate cancer as well as other forms of cancer. | Muhammedin Deliorman Farhad K.Janahi Pavithra Sukumar Ayoub Glia Roaa Alnemari Samar Fadl Weiqiang Chen Mohammad A.Qasaimeh | 2020 | Microsystems & Nanoengineering2020，6，1： | 2 |
