| 5 | Hepatocellular adenoma: An update显示文摘Hepatocellular adenomas(HCA) are rare benign liver tumors.Recent technological advancements have helped in the early identification of such lesions.However,precise diagnosis of hepatocellular incidentalomas remains challenging.Studies at the molecular level have provided new insights into the genetics and pathophysiology of these lesions.These in turn have raised questions over their existing management modalities.However,the rarity of the tumor still restricts the quality of evidence available for current recommendations and guidelines.This article provides a comprehensive review on the etiology,molecular biology,pathophysiology,clinical manifestations,and complications associated with HCA.It also elaborates on the genetic advancements,existing diagnostic tools and current guidelines for management for such lesions. | Adarsh Vijay Ahmed Elaffandi Hatem Khalaf | 2015 | World Journal of Hepatology2015，7，25： | 12 |
| 6 | Evaluation of Protein Extraction Methods for Vitis vinifera Leaf and Root Proteome Analysis by Two-Dimensional Electrophoresis显示文摘An efficient protein extraction method is crucial to ensure successful separation by two-dimensional electrophoresis(2-DE) for recalcitrant plant species,in particular for grapevine(Vitis vinifera L.).Trichloroacetic acid-acetone(TCA-acetone) and phenol extraction methods were evaluated for proteome analysis of leaves and roots from the Tunisian cultivar 'Razegui'.The phenol-based protocol proved to give a higher protein yield,a greater spot resolution,and a minimal streaking on 2-DE gels for both leaf and root tissues compared with the TCA-based protocol.Furthermore,the highest numbers of detected proteins on 2-DE gels were observed using the phenol extraction from leaves and roots as compared with TCA-acetone extraction. | Neila Jellouli Asma Ben Salem Abdelwahed Ghorbel Hatem Ben Jouira | 2010 | Journal of Integrative Plant Biology2010，52，10： | 12 |
| 7 | The effects of the rotor-stator interaction on unsteady pressure pulsation and radial force in a centrifugal pump显示文摘An unsteady numerical analysis has been conducted to study the strong interaction between impeller blade and volute tongue of a centrifugal pump. The 3-D-URANS equations were solved with the shear stress transport turbulence model for a wide range of flow rates. These unsteady interactions are mostly related to the unsteady radial force due to an imbalance in the pressure field at the impeller periphery. This force represents dynamic load that are one of the most important sources of vibration and hydraulic noise. Based on this phenomenon, this work analyzes and gives a more realistic prediction of the pressure fluctuation and the radial force during steady and unsteady calculation by considering the effect of the change in the pump operating point. Actually, the pressure fluctuations in the impeller and the volute were recorded by mounting nine monitoring points on the impeller and volute casing. The results of the existing analysis has proven that the pressure fluctuation is periodic due to the relative position of impeller blade to volute tongue. The characteristics of the time domain and frequency domain of the pressure pulsation were analyzed under different coupling conditions. Fast Fourier transform was performed to obtain the spectra of pressure pulsation. Besides, the steady and unsteady forces were calculated around the impeller periphery to fully characterize the pump behavior. The obtained pump performance curves were numerically compared with the experimental ones, and the outcome have shown an acceptable agreement between both curves. | Issa Chalghoum Sami Elaoud Hatem Kanfoudi Mohsen Akrout | 2018 | Journal of Hydrodynamics2018，30，4： | 12 |
| 8 | Diffusion-weighted magnetic resonance imaging and micro-RNA in the diagnosis of hepatic fibrosis in chronic hepatitis C virus显示文摘BACKGROUND Diffusion-weighted magnetic resonance imaging has shown promise in the detection and quantification of hepatic fibrosis. In addition, the liver has numerous endogenous micro-RNAs(miRs) that play important roles in the regulation of biological processes such as cell proliferation and hepatic fibrosis.AIM To assess diffusion-weighted magnetic resonance imaging and miRs in diagnosing and staging hepatic fibrosis in patients with chronic hepatitis C.METHODS This prospective study included 208 patients and 82 age-and sex-matched controls who underwent diffusion-weighted magnetic resonance imaging of the abdomen, miR profiling, and liver biopsy. Pathological scoring was classified according to the METAVIR scoring system. The apparent diffusion coefficient (ADC) and miR were calculated and correlated with pathological scoring.RESULTS The ADC value decreased significantly with the progression of fibrosis, from controls(F0) to patients with early fibrosis(F1 and F2) to those with late fibrosis(F3 and F4)(median 1.92, 1.53, and 1.25 × 10^(-3) mm^2/s, respectively)(P = 0.001).The cut-off ADC value used to differentiate patients from controls was 1.83 × 10^(-3) mm^2/s with an area under the curve(AUC) of 0.992. Combining ADC and miR-200 b revealed the highest AUC(0.995) for differentiating patients from controls with an accuracy of 96.9%. The cut-off ADC used to differentiate early fibrosis from late fibrosis was 1.54 × 10^(-3) mm^2/s with an AUC of 0.866. The combination of ADC and miR-200 b revealed the best AUC(0.925) for differentiating early fibrosis from late fibrosis with an accuracy of 80.2%. The ADC correlated with miR-200 b(r =-0.61, P = 0.001), miR-21(r =-0.62, P = 0.001), and miR-29(r = 0.52,P = 0.001).CONCLUSION Combining ADC and miRs offers an alternative surrogate non-invasive diagnostic tool for diagnosing and staging hepatic fibrosis in patients with chronic hepatitis C. | Tarek Besheer Hatem Elalfy Mohamed Abd El-Maksoud Ahmed Abd El-Razek Saher Taman Khaled Zalata Wagdy Elkashef Hossam Zaghloul Heba Elshahawy Doaa Raafat Wafaa Elemshaty Eman Elsayed Abdel-Hady El-Gilany Mahmoud El-Bendary | 2019 | World Journal of Gastroenterology2019，25，11： | 9 |
| 9 | Photosynthetic, Physiological and Biochemical Responses of Tomato Plants to Polyethylene Glycol-Induced Water Deficit显示文摘Polyethylene glycol (PEG 6000)-induced water deficit causes physiological as well as biochemical changes in plants. The present study reports on the results of such changes in hydroponically grown tomato plants (Lycopersicon esculentum Mill. cv. Nikita). Plants were subjected to moderate and severe levels of water stress (i.e. water potentials in the nutrient solution of-0.51 and -1.22 MPa, respectively).Water stress markedly affected the parameters of gas exchange. Net photosynthetic rate (Pn) decreased with the induction of water stress. Accordingly, a decrease in the transpiration rate (E) was observed. The ratio of both (Pn/E) resulted in a decrease in water use efficiency. One of the possible reasons for the reduction in Pn is structural damage to the thylakoids, which affects the photosynthetic transport of electrons. This was indicated by an increase in non-photochemical quenching and a reduction in the quantum yield of photosystem Ⅱ. Furthermore, a decrease in both leaf water potential and leaf osmotic potential was observed, which resulted in a significant osmotic adjustment during stress conditions. Analysis of the physiological responses was complemented with a study on changes in proline content. In stressed plants, a 10-fold increase in proline content was detected compared with control plants. It is clear that water stress tolerance is the result of a cumulative action of various physiological and biochemical processes, all of which were affected by PEG 6000-induced water stress. | Hatem ZGALLAI Kathy STEPPE Raoul LEMEUR | 2005 | Journal of Integrative Plant Biology2005，47，12： | 6 |
| 10 | Non-invasive assessment of choledocholithiasis in patients with gallstones and abnormal liver function显示文摘AIM:To find a non-invasive strategy for detecting choledocholithiasis before cholecystectomy,with an acceptable negative rate of endoscopic retrograde cholangiopancreatography.METHODS:All patients with symptomatic gallstones were included in the study.Patients with abnormal liver functions and common bile duct abnormalities on ultrasound were referred for endoscopic retrograde cholangiopancreatography.Patients with normal ultrasoundwere referred to magnetic resonance cholangiopancreatography.All those who had a negative magnetic resonance or endoscopic retrograde cholangiopancreatography underwent laparoscopic cholecystectomy with intraoperative cholangiography.RESULTS:Seventy-eight point five percent of patients had laparoscopic cholecystectomy directly with no further investigations.Twenty-one point five percent had abnormal liver function tests,of which 52.8%had normal ultrasound results.This strategy avoided unnecessary magnetic resonance cholangiopancreatography in 47.2%of patients with abnormal liver function tests with a negative endoscopic retrograde cholangiopancreatography rate of 10%.It also avoided un-necessary endoscopic retrograde cholangiopancreatography in 35.2%of patients with abnormal liver function.CONCLUSION:This strategy reduces the cost of the routine use of magnetic resonance cholangiopancreatography,in the diagnosis and treatment of common bile duct stones before laparoscopic cholecystectomy. | Bilal O Al-Jiffry Abdeen Elfateh Tariq Chundrigar Bassem Othman Owaid AlMalki Fares Rayza Hashem Niyaz Hesham Elmakhzangy Mohammed Hatem | 2013 | World Journal of Gastroenterology2013，19，35： | 6 |
| 11 | Six Minute Walk Test to assess functional capacity in chronic liver disease patients显示文摘AIM: To examine the utility of Six Minute Walk Test (6MWT) in patients with chronic liver disease (CLD). METHODS: Two hundred and fifty subjects between the ages of 18 and 80 (mean 47) years performed 6MWT and the Six Minute Walk Distance (6MWD) was measured. RESULTS: The subjects were categorized into four groups. Group A (n = 45) healthy subjects (control); group B (n = 49) chronic hepatitis B patients; group C (n = 54) chronic hepatitis C patients; group D (n = 98) liver cirrhosis patients. The four groups differed in terms of 6MWDs (P < 0.001). The longest distance walked was 421 ± 47 m by group A, then group B (390 ± 53 m), group C (357 ± 72 m) and group D (306 ± 111 m). The 6MWD correlated with age (r = -0.482, P < 0.01), hemoglobin (r = +0.373, P < 0.001) and albumin (r = +0.311, P < 0.001) levels. The Child-Pugh classification was negatively correlated with the 6MWD in cirrhosis (group D) patients (r = -0.328, P < 0.01). At the end of a 12 mo follow-up period, 15 of the 98 cirrhosis patients had died from disease complications. The 6MWD for the surviving cirrhotic patients was longer than for non-survivors (317 ± 101 vs 245 ± 145 m, P = 0.021; 95% CI 11-132). The 6MWD was found to be an independent predictor of survival (P = 0.024). CONCLUSION: 6MWT is a useful tool for assessing physical function in CLD patients. We suggest that 6MWD may serve as a prognostic indicator in patients with liver cirrhosis. | Hatem F Alameri Faisal M Sanai Manal Al Dukhayil Nahla A Azzam Khalid A Al-Swat Ahmad S Hersi Ayman A Abdo | 2007 | World Journal of Gastroenterology2007，13，29： | 5 |
| 12 | Diagnostic non-invasive model of large risky esophageal varices in cirrhotic hepatitis C virus patients显示文摘AIM To build a diagnostic non-invasive model for screening of large varices in cirrhotic hepatitis C virus(HCV) patients. METHODS This study was conducted on 124 post-HCV cirrhotic patients presenting to the clinics of the Endemic Medicine Department at Mansoura University Hospital for evaluation before HCV antiviral therapy: 78 were Child A and 46 were Child B(score ≤ 8). Inclusion criteria for patients enrolled in this study was presence of cirrhotic HCV(diagnosed by either biopsy or fulfillment of clinical basis). Exclusion criteria consisted of patients with other etiologies of liver cirrhosis, e.g., hepatitis B virus and patients with high MELD score on transplant list. All patients were subjected to full medical record, full basic investigations, endoscopy, and computed tomography(CT), and then divided into groups with no varices, small varices, or large risky varices. In addition, values of Fibrosis-4 score(FIB-4), aminotransferase-to-platelet ratio index(APRI), and platelet count/splenic diameter ratio(PC/SD) were also calculated.RESULTS Detection of large varies is a multi-factorial process, affected by many variables. Choosing binary logistic regression, dependent factors were either large or small varices while independent factors included CT variables such coronary vein diameter, portal vein(PV) diameter, lieno-renal shunt and other laboratory noninvasive variables namely FIB-4, APRI, and platelet count/splenic diameter. Receiver operating characteristic(ROC) curve was plotted to determine the accuracy of non-invasive parameters for predicting the presence of large esophageal varices and the area under the ROC curve for each one of these parameters was obtained. A model was established and the best model for prediction of large risky esophageal varices used both PC/SD and PV diameter(75% accuracy), while the logistic model equation was shown to be(PV diameter ×-0.256) plus(PC/SD ×-0.006) plus(8.155). Values nearing 2 or more denote large varices.CONCLUSION This model equation has 86.9% sensitivity and 57.1% specificity, and would be of clinical applicability with 75% accuracy. | Hatem Elalfy Walid Elsherbiny Ashraf Abdel Rahman Dina Elhammady Shaker Wagih Shaltout Ayman Z Elsamanoudy Bassem El Deek | 2016 | World Journal of Hepatology2016，8，24： | 5 |
| 13 | Termites and Chinese agricultural system: applications and advances in integrated termite management and chemical control显示文摘Termites are eusocial arthropod decomposers,and improve soil fertility,crop yield,and also are used by humans for their ben efits across the world.However,some species of termites are becoming a threat to the farming community as they are directly and indirectly causing major losses to the agricultural system.It is estimated that termites cost the global economy more than 40 billion USD annually,and considerable research has been done on their management.In this review,we present the available information related to sustainable and integrated termite management practices(ITM).Furthermore,we insist that the better management of this menace can be possible through:(i)improving traditional methods to keep termites away from crops;(ii)improving agricultural practices to maintain plants with more vigor and less susceptible to termite attack;and(iii)integration of available techniques to reduce termite infestation in crops and surroundings.The application of an effective combination of traditional practices with recently developed approaches is the best option for agricultural growers.Moreover,keeping in mind the beneficial nature of this pest,more innovative efforts for its management,particularly using rapidly emerging technology(e.g.,RNA interference),are needed. | Farhan Ahmad Hatem Fouad Shi-You Liang Yin Hu Jian-Chu Mo | 2021 | Insect Science2021，28，1： | 5 |
| 14 | Identification of gas zones and chimneys using seismic attributes analysis at the Scarab field,offshore,Nile Delta,Egypt显示文摘Seismic attributes supported by composite logs are the best way that can enable the interpreter to understand seismic data very well and generate a new view of the output results.Detection of the reservoir zone can be enhanced by analyzing wells log data based on Gamma-ray,Resistivity,and Vp sonic logs respectively.Composite logs of Scarab-1,Scarab-De,Scarab-Da,Scarab-Dd,and Scarab-2 wells indicate the lateral and vertical variation of the gas reservoir in ElWastani Formation.However,there are several seismic attributes that can be used to support reservoirs identification.For enhancement the detection of the hydrocarbon reservoirs,it is important to carefully analyze the 2D seismic data,which in this study will be primarily prepared to enhance seismic attributes results for the identification of gas chimneys,gas zones as channels,enhance stratigraphic and structural interpretations.In this article,we have performed data conditioning,quality control and seismic well ties including the preliminary wavelet extractions to get accurate output.Then,we have extracted of several classes of physical,geometrical and complex attributes as a direct hydrocarbon indicator to identify the gas zones,channels and chimneys and to identify the faults and discontinuities.The main contribution of this work is to provide a more detailed seismic reflection image supported by several seismic attributes classes and well logs to show a visual and quantitative evidence to identify the gas channels and gas chimneys with improving the detection of the faults and discontinuities. | Amir Ismail Hatem Farouk Ewida Mohammad Galal Al-Ibiary Sergio Gammaldi Aldo Zollo | 2020 | Petroleum Research2020，5，1： | 4 |

They were divided randomly into two groups: Group A included 72 eyes treated with t-PRK with adjuvant MMC and Group B included 84 eyes treated with Femto-LASIK. Visual acuity, SER, corneal topography, pachymetry and keratometry were assessed for 12 mo postoperatively.RESULTS: The preoperative mean SER was-8.86±1.81 and-9.25±1.70 D in t-PRK MMC group and Femto-LASIK respectively(P=0.99) which improved to-0.65±0.43 D and-0.69±0.50 D at 12 mo follow up. Mean SER remained stable during the 12 mo of follow-up, with no statistically significant difference between the two groups(P=0.64). In t-PRK MMC group, only six eyes needed retreatment after six months of follow up. And two eyes showed haze(one reversible haze grade 2, while the other had dense irreversible haze grade 4).CONCLUSION: t-PRK MMC provides safe and satisfactory visual outcomes and acceptable risk as Femto-LASIK in patients with high myopia. | Amr Mounir Engy Mohamed Mostafa Hatem Ammar Osama Ali Mohammed Alahmady Hamad Alsmman Mahmoud Mohamed Farouk Mohamed Gamal Elghobaier | 2020 | International Journal of Ophthalmology(English edition)2020，13，1： | 4 |
| 16 | A reliability study of springback on the sheet metal forming process under probabilistic variation of prestrain and blank holder force显示文摘This work deals with a reliability assessment of springback problem during the sheet metal forming process. The effects of operative parameters and material properties, blank holder force and plastic prestrain, on springback are investigated. A generic reliability approach was developed to control springback. Subsequently, the Monte Carlo simulation technique in conjunction with the Latin hypercube sampling method was adopted to study the probabilistic springback. Finite element method based on implicit/explicit algorithms was used to model the springback problem. The proposed constitutive law for sheet metal takes into account the adaptation of plastic parameters of the hardening law for each prestrain level considered. Rackwitz-Fiessler algorithm is used to find reliability properties from response surfaces of chosen springback geometrical parameters. The obtained results were analyzed using a multi-state limit reliability functions based on geometry compensations. | Hatem Mrad Mohamed Bouazara Gholamreza Aryanpour | 2013 | Acta Mechanica Sinica2013，29，4： | 4 |
