| 2 | Is it time to replace propranolol with carvedilol for portal hypertension?显示文摘Beta-adrenergic receptor antagonists(β-blockers) have been well established for use in portal hypertension for more than three decades. Different Non-selective β-blockers like propranolol, nadolol, timolol, atenolol, metoprolol and carvedilol have been in clinical practice in patients with cirrhosis. Carvedilol has proven 2-4 times more potent than propranolol as a beta-receptor blocker in trials conducted testing its efficacy for heart failure. Whether the same effect extends to its potency in the reduction of portal venous pressures is a topic of on-going debate. The aim of this review is to compare the hemodynamic and clinical effects of carvedilol with propranolol, and attempt assess whether carvedilol can be used instead of propranolol in patients with cirrhosis. Carvedilol is a promising agent among the beta blockers of recent time that has shown significant effects in portal hypertension hemodynamics. It has also demonstrated an effective profile in its clinical application specifically for the prevention of variceal bleeding. Carvedilol has more potent desired physiological effects when compared to Propranolol. However, it is uncertain at the present juncture whether the improvement in hemodynamics also translates into a decreased rate of disease progression and complications when compared to propranolol. Currently Carvedilol shows promise as a therapy for portal hypertension but more clinical trials need to be carried out before we can consider it as a superior option and a replacement for propranolol. | Shahab Abid Saadat Ali Muhammad Asif Baig Anam Akbar Waheed | 2015 | World Journal of Gastrointestinal Endoscopy2015,7,5: | 13 |
| 3 | An ANN-based approach to predict blast-induced ground vibration of Gol-E-Gohar iron ore mine,Iran显示文摘Blast-induced ground vibration is one of the inevitable outcomes of blasting in mining projects and may cause substantial damage to rock mass as well as nearby structures and human beings.In this paper,an attempt has been made to present an application of artificial neural network(ANN)to predict the blast-induced ground vibration of the Gol-E-Gohar(GEG)iron mine,Iran.A four-layer feed-forward back propagation multi-layer perceptron(MLP)was used and trained with Levenberg–Marquardt algorithm.To construct ANN models,the maximum charge per delay,distance from blasting face to monitoring point,stemming and hole depth were taken as inputs,whereas peak particle velocity(PPV)was considered as an output parameter.A database consisting of69data sets recorded at strategic and vulnerable locations of GEG iron mine was used to train and test the generalization capability of ANN models.Coefficient of determination(R2)and mean square error(MSE)were chosen as the indicators of the performance of the networks.A network with architecture4-11-5-1and R2of0.957and MSE of0.000722was found to be optimum.To demonstrate the supremacy of ANN approach,the same69data sets were used for the prediction of PPV with four common empirical models as well as multiple linear regression(MLR)analysis.The results revealed that the proposed ANN approach performs better than empirical and MLR models. | Mahdi Saadat Manoj Khandelwal M.Monjezi | 2014 | Journal of Rock Mechanics and Geotechnical Engineering2014,6,1: | 7 |

| 5 | Analysis of shear rate effects on drag reduction in turbulent channel flow with superhydrophobic wall显示文摘We examined the shear rate effect on drag reduction of superhydrophobic surfaces with different slip lengths.For this purpose,turbulent channel flow was considered at the friction Reynolds numbers of Re=180,395,500.By using Navier’s slip condition it is shown that increasing shear rate leads to the greater reduction in drag force and also more reduction occurs in larger slip length.Based on the results,more than 25%drag reduction happens at a friction Reynolds number of Re=500 for slip length of 1×10–5m.The simulation results suggest that reduction in drag force occurs because slip condition reduces the Reynolds stresses,also weakens vorticity filed and the near-wall coherent structures,and therefore turbulence production is decreased. | NOURI Nowrouz Mohammad BAKHSH Mohammad Saadat SEKHAVAT Setareh | 2013 | Journal of Hydrodynamics2013,25,6: | 5 |

| 8 | Seven-day quintuple regimen as a rescue therapy for Helicobacter pylori eradication显示文摘AIM: To determine the efficacy of two quintupleregimens for eradication of Helicobacter pylori(H. pylori) in patients who failed previous therapies.METHODS: This prospective, open-label, randomized controlled trial was a phase Ⅱ study conducted from April 2011 to March 2012 at the Gastrointestinal and Liver Diseases Research Center in Rasht, Iran. A total of 208 patients with dyspepsia who failed previous H. pylori eradication with a ten-day quadruple therapy were enrolled. A random block method was used to assign patients to one of two treatment groups. Patients in the first group were treated with 240 mg bismuth subcitrate, 20 mg omeprazole, 1000 mg amoxicillin, 500 mg clarithromycin and 500 mg tinidazole(BOACT group). Patients in the second group received a regimen containing 240 mg bismuth subcitrate, 20 mg omeprazole, 500 mg tetracycline, 500 mg metronidazole and 200 mg ofloxacin(BOTMO group). Both regimens were given twice daily for a duration of seven days. The eradication was confirmed by a 14 C urea breath test 12 wk after completion of therapy. Patient compliance and drug side effects were evaluated at the end of the treatment period. The success rates were calculated by intention-to-treat and per-protocol analyses.RESULTS: A total of 205 patients completed the course of treatment, with three patients excluded due to drug intolerance. The mean age of patients did not differ between the BOACT and BOTMO groups(41.6 ± 12.2 years vs 39.6 ± 11.8 years), and no significant differences were found between the two groups in terms of age, sex, smoking habits or the initial eradication regimen. The intention-to-treat and perprotocol eradication rates were significantly higher in the BOTMO group(86.5%, 95%CI: 0.85-0.87 and 86.7%, 95%CI: 0.80-0.89, respectively) compared with the BOACT group(75.5%, 95%CI: 0.73-0.76 and 76%, 95%CI: 0.69-0.80, respectively)(P < 0.05). Univariate analyses for both groups did not show any association of sex, smoking and initial therapeutic regimen witheradiation rate(P > 0.05 for all). Significantly more patients experienced side effects in the BOACT group compared to the BOTMO group(77.4% vs 36.6%, P < 0.01). This difference was exemplified by increases in headache and taste disturbance(P < 0.05).CONCLUSION: Quintuple therapy with a BOTMO regimen is an alternative second-line rescue therapy for Iranian patients with failed first-line eradication treatment of H. pylori. | Fariborz Mansour-Ghanaei Farahnaz Joukar Mohammad Reza Naghipour Atena Forouhari Seyed Mohammad Seyed Saadat | 2015 | World Journal of Gastroenterology2015,21,2: | 2 |

| 10 | Effect of soil pore size distribution on plant-available water and least limiting water range as soil physical quality indicators显示文摘Soil pore size distribution(SPSD) is one of the most important soil physical properties. This research investigated the relationships of location and shape parameters of the SPSD curves with plant-available water(PAW) and least limiting water range(LLWR) of the light-textured soils at the Torogh Agricultural Research Station in north-eastern Iran. Soil moisture release curve(SMRC), PAW and LLWR in matric heads of 100 and 330 h Pa for the field capacity and location and shape parameters of the SPSD curves of 30 soils with different texture and organic carbon contents were determined, and the variable relationships were statistically analyzed. The results showed that the median equivalent pore diameter(de), mean de, standard deviation(SD*), and skewness of the SPSD curves were significantly correlated with PAW(PAW330) and LLWR(LLWR330) measured in a matric head of 330 h Pa. Decrease in deand increase in the diversity of soil pore size(SD*) increased PAW330 and LLWR330. The SD* values of all the soil samples were lower than the optimal ranges suggested in literature. Neither PAW nor LLWR values were significantly different in the soils with the optimal modal deand those with non-optimal modal de. Optimal values of median and mean equivalent pore diameters and kurtosis of SPSD curves led to a significant improvement of PAW330 and LLWR330 as soil physical quality indicators. It was recommended to revise the optimal ranges for SD* and modal defor future studies. | Mehdi ZANGIABADI Manoochehr GORJI Mehdi SHORAFA Saeed KHAVARI KHORASANI Saeed SAADAT | 2020 | Pedosphere2020,30,2: | 2 |
