| 1 | Effects of different periods of renal ischemia on liver as a remote organ显示文摘AIM:To assess the hepatic changes after induction of different periods of renal ischemia. METHODS:Rats were subjected to either sham operation or ischemia (30,45 and 60 min) followed by 60 min reperfusion. Liver and renal functional indices were measured. Hepatic glutathione (GSH) and ferric reducing antioxidant power levels and the concentration of interleukin (IL)-10 and tumor necrosis factor (TNF-α) were evaluated. Portions of liver and kidney tissues were fixed for histological evaluation. RESULTS:Forty-five minutes renal ischemia followed by 60 min reperfusion caused significant changes in liver structure and a significant reduction in renalfunction. These rats showed a significant decrease in liver GSH,as well as a significant increase in TNF-α and IL-10 concentrations. These results demonstrated that renal ischemia caused changes in liver histology,function,oxidative stress and inflammatory status,which led to a reduction in hepatic antioxidant capacity. With 30 min ischemia,the magnitude of these changes was less than those with 45 or 60 min ischemia.CONCLUSION:A minimum of 45 min ischemia is needed to study the effects of renal injury on the liver as a remote organ. | Mehri Kadkhodaee Fereshteh Golab Maryam Zahmatkesh Rana Ghaznavi Mehdi Hedayati Hossein Ali Arab Seyed Naser Ostad Manoocher Soleimani | 2009 | World Journal of Gastroenterology2009，15，9： | 5 |

| 3 | Application of Stool-PCR test for diagnosis of Helicobacter pylori infection in children显示文摘AIM:To evaluate the usefulness of stool-PCR test for diagnosis of Helicobacter pylori(H pylori)infection in pediatric populations. METHODS:Based on endoscopic features(including nodular gastritis,erosive duodenitis and ulcer)and/or a positive rapid urease test(RUT)obtained during endoscopy,28 children from a group of children admitted to the Children's Medical Center of Tehran for persistent upper gastrointestinal problems were selected to compare biopsy-based tests with stoolPCR.Their gastric activity and bacterial density were graded by the updated Sydney system,and their first stool after endoscopy was stored at-70℃.Biopsies were cultured on modified campy-blood agar plates and identified by gram-staining,biochemical tests,and PCR.Two methods of phenol-chloroform and boiling were used for DNA extraction from H pylori isolates. Isolation of DNA from stool was performed using a stool DNA extraction kit(Bioneer Inc,Korea).PCR was performed using primers for detection of vacA,cagA,and 16srRNA genes in both isolates and stool. RESULTS:Sixteen out of 28 child patients(57%) were classified as H pylori positive by biopsy-based tests,of which 11(39%)were also positive by stoolPCR.Sensitivity and specificity of stool-PCR was 62.5% and 92.3%respectively.H pylori was observed in histological sections for 10 out of 11 stool-positivepatients.Association was observed between higher score of H pylori in histology and positivity of stoolPCR.Also association was observed between the more severe form of gastritis and a positive stool-PCR. CONCLUSION:Association between higher score of H pylori in histology and a positive stool-PCR make it a very useful test for detection of H pylori active infection in children.We also suggest that a simple stool-PCR method can be a useful test for detection of H pylori virulence genes in stool. | Tahereh Falsafi Raha Favaedi Fatemeh Mahjoub Mehri Najafi | 2009 | World Journal of Gastroenterology2009，15，4： | 5 |
| 4 | Assessing dynamic response of multispan viscoelastic thin beams under a moving mass via generalized moving least square method显示文摘Dynamic response of multispan viscoelastic thin beams subjected to a moving mass is studied by an efficient numerical method in some detail.To this end,the unknown parameters of the problem are discretized in spatial domain using generalized moving least square method(GMLSM) and then,discrete equations of motion based on Lagrange's equation are obtained.Maximum deflection and bending moments are considered as the important design parameters.The design parameter spectra in terms of mass weight and velocity of the moving mass are presented for multispan viscoelastic beams as well as various values of relaxation rate and beam span number.A reasonable good agreement is achieved between the results of the proposed solution and those obtained by other researchers.The results indicate that,although the load inertia effects in beams with higher span number would be intensified for higher levels of moving mass velocity,the maximum values of design parameters would increase either.Moreover,the possibility of mass separation is shown to be more critical as the span number of the beam increases.This fact also violates the linear relation between the mass weight of the moving load and the associated design parameters,especially for high moving mass velocities.However,as the relaxation rate of the beam material increases,the load inertia effects as well as the possibility of moving mass separation reduces. | Keivan Kiani Ali Nikkhoo Bahman Mehri | 2010 | Acta Mechanica Sinica2010，26，5： | 3 |
| 5 | 采用微分脉冲伏安法和碳纳米管改性电极测定咖啡因(英文)显示文摘A simple and sensitive electrochemical detection of caffeine(CAF) using a single-walled carbon nanotubes on carbon-ceramic electrode(SWCNT/CCE) is reported.CAF was oxidized at the surface of the modified electrode to produce an anodic peak at 1.38 V versus the saturated calomel electrode in 0.01 mol/L,pH 1.7 H2SO4 solution in cyclic voltammetry.The experimental parameters,namely,type of electrolyte,pH value,and amount of SWCNTs casted,were optimized.Using the optimum conditions,the anodic peak current in differential pulse voltammetry was linear with CAF concentration in the range of 2.5 × 10 7 1.0 × 10 4 mol/L.The detection limit was 1.2 × 10 7 mol/L(S/N = 3).The modified electrode exhibited good stability and can be easily regenerated.The relative standard deviation of the peak current obtained for a 5.0 × 10 5 mol/L CAF solution was 3.0%.The influence of some important biological compounds,namely,ascorbic acid,dopamine,and uric acid and addictive compounds like codeine,morphine,and acetaminophen on the CAF anodic peak current was examined.The method was successfully applied for the determination of CAF in some practical samples. | Biuck HABIBI Mehri ABAZARI Mohammad Hossien POURNAGHI-AZAR | 2012 | 催化学报2012，33，11： | 2 |
| 6 | A two-stage DEA model to evaluate sustainability and energy efficiency of tomato production显示文摘The aims of this study were to evaluate the sustainability and efficiency of tomato production and to investigate the determinants of inefficiency of tomato farming in Marand region of East Azerbaijan province,Iran.For these purposes,a two-stage methodology was applied,in which for the first time a fractional regression model(FRM)was employed in the second stage of analysis,so that,in the first stage a nonparametric Data Envelopment Analysis(DEA)was used to analyze the efficiencies of tomato production and in the second stage,farm specific variables such as education level,farmers’age,total land size and use of manure were used in a fractional regression model to explain how these factors influenced efficiency of tomato farming.The results of the first stage showed that there are considerable differences between efficient and inefficient farmers in the studied area,so that the main differences were in the use of chemical fertilizers,biocides and water for irrigation.Also,the results of second stage revealed that farmers’age,education level and total land size positively affected efficiency in tomato production.So,better use of land,chemical fertilizers,water for irrigation and improving the farmers’educational levels through literacy campaign and land consolidation would probably increase the efficiency in the long term. | Hossein Raheli Rassul Mohammad Rezaei Mehri Raei Jadidi Hassan Ghasemi Mobtaker | 2017 | Information Processing in Agriculture2017，4，4： | 2 |
| 7 | TiO_(2)纳米颗粒对7075铝合金表面等离子体电解氧化涂层性能的影响显示文摘采用等离子体电解氧化(PEO)技术,利用单极脉冲波形在含有胶体TiO_(2)纳米颗粒的溶胶电解液中制备Al_(2)O_(3)−TiO_(2)复合涂层。溶胶溶液是将1、3和5 g/L的草酸钛酸钾(PTO)溶解在硅酸盐溶液中制得。利用扫描电镜、能量色散光谱、X射线衍射和拉曼光谱对涂层进行表征。采用极化和阻抗技术研究涂层的腐蚀行为。结果表明,TiO_(2)通过微放电方式进入涂层,并掺杂到氧化铝相中。TiO_(2)掺入量较高时,表面微孔减少;反之,掺入量较低时则微孔增多。TiO_(2)含量越高,涂层的外层越致密,内层越厚。电化学测试结果表明,与在不含PTO溶液中制备的涂层相比,在含3 g/L PTO溶液中制备的涂层腐蚀性能得到大幅提高。在不含PTO溶液中制备的涂层含有γ-Al_(2)O_(3),δ-Al_(2)O_(3)和非晶相,而PTO的存在促进α-Al_(2)O_(3)的生成。 | Mehri HASHEMZADEH Keyvan RAEISSI Fakhreddin ASHRAFIZADEH Amin HAKIMIZAD Monica SANTAMARIA | 2021 | Transactions of Nonferrous Metals Society of China2021，31，12： | 2 |
| 8 | Performance assessment of a spiral methanol to hydrogen fuel processor for fuel cell applications显示文摘A novel design of plate-type microchannel reactor has been developed for fuel cell-grade hydrogen production.Commercial Cu/Zn/Al2O3 was used as catalyst for the reforming reaction,and its effectiveness was evaluated on the mole fraction of products,methanol conversion,hydrogen yield and the amount of carbon monoxide under various operating conditions.Subsequently,0.5 wt% Ru/Al2O3 as methanation catalyst was prepared by impregnation method and coupled with MSR step to evaluate the capability of methanol processor for CO reduction.Based on the experimental results,the optimum conditions were obtained as feed flow rate of 5mL/h and temperature of 250℃,leading to a low CO selectivity and high H2 yield.The designed reformer with catalyst coated layer was compared with the conventional packed bed reformer at the same operating conditions.The constructed fuel processor had a good performance and excellent capability for on-board hydrogen production. | Foad Mehri Majid Taghizadeh | 2012 | Journal of Natural Gas Chemistry2012，21，5： | 2 |
