| 1 | Portal hemodynamics as predictors of high risk esophageal varices in cirrhotic patients显示文摘AIM: To evaluate portal hypertension parameters in liver cirrhosis patients with and without esophageal varices (EV). METHODS: A cohort of patients with biopsy confirmed liver cirrhosis was investigated endoscopically and with color Doppler ultrasonography as a possible non-invasive predictive tool. The relationship between portal hemodynamics and the presence and size of EV was evaluated using uni-and multivariate approaches. RESULTS: Eighty five consecutive cirrhotic patients (43 men and 42 women) were enrolled. Mean age (± SD) was 47.5 (± 15.9). Portal vein diameter (13.88 ± 2.42 vs 12.00 ± 1.69, P < 0.0005) and liver vascular index (8.31 ± 2.72 vs 17.8 ± 6.28, P < 0.0005) were found to be significantly higher in patients with EV irrespective of size and in patients with large varices (14.54 ± 1.48 vs 13.24 ± 2.55, P < 0.05 and 6.45 ± 2.78 vs 10.96 ± 5.05, P < 0.0005, respectively), while portal vein flow velocity (13.25 ± 3.66 vs 20.25 ± 5.05, P < 0.0005), congestion index (CI) (0.11 ± 0.03 vs 0.06 ± 0.03, P < 0.0005), portal hypertensive index (2.62 ± 0.79 vs 1.33 ± 0.53, P < 0.0005), and hepatic (0.73 ± 0.07 vs 0.66 ± 0.07, P < 0.001) and splenic artery resistance index (RI) (0.73 ± 0.06 vs 0.62 ± 0.08, P < 0.0005) were significantly lower. A logistic regression model confirmed spleen size (P = 0.002, AUC 0.72) and portal hypertensive index (P = 0.040, AUC 0.79) as independent predictors for the occurrence of large esophageal varices (LEV). CONCLUSION: Our data suggest two independent situations for beginning endoscopic evaluation ofcompensated cirrhotic patients: Portal hypertensive index > 2.08 and spleen size > 15.05 cm. These factors may help identifying patients with a low probability of LEV who may not need upper gastrointestinal endoscopy. | Mohammad K Tarzamni Mohammad H Somi Sara Farhang Morteza Jalilvand | 2008 | World Journal of Gastroenterology2008,14,12: | 15 |
| 2 | Nitrogen in Relation to Photosynthetic Capacity and Accumulation of Osmoprotectant and Nutrients in Brassica Genotypes Grown Under Salt Stress显示文摘Different strategies of the application of nutrients are required to overcome the adverse effects of mustard (Brassica juncea L.) in response to NaCl stress. The objective of the present study was to determine if different added levels of nitrogen (N) in growth medium could alleviate the adverse effects of salt stress on photosynthetic capacity and accumulation of osmoprotectants and nutrients. 14 days mustard seedlings of salt-sensitive (cv. Chuutki) and salt-tolerant (cv. Radha) genotypes were fed with: (i) 0 mmol L-1 NaCl + 0 mg N kg-1 sand (control), (ii) 90 mmol L-1 NaCl + 30 mg N kg-1 sand, (iii) 90 mmol L-1 NaCl + 60 mg N kg-1 sand, (iv) 90 mmol L-1 NaCl + 90 mg N kg-1 sand and (v) 90 mmol L-1 NaCl + 120 mg N kg-1 sand. Under the condition of salinity stress, N application caused a significant ameliorative effect on both genotypes with respect to growth attributes [fresh weight (FW) and dry weight (DW)] and physio-biochemical parameters [percent water content (WC), net photosynthetic rate (PN), stomatal conductance (gs), total chlorophyll (Chl), carbonic anhydrase (CA) activity and malondialdehyde (MDA), nitrogen (N), potassium (K) and sodium (Na) contents, and K/Na ratio] and yield attributes (number of pods/plant, seeds/pod and seed yield/plant). The salt-tolerant genotype exhibited maximum value for growth, physio-biochemical and yield attributes at 60 mg N kg-1 sand than that of salt-sensitive genotype. These results suggest that application of N may ameliorate most of the attributes and prove to be a physiological remedy to increase the tolerance against the ill effects of salt stress in Brassicas. | Manzer H Siddiqui Firoz Mohammad M Nasir Khan Mohamed H Al-Whaibi Ali H A Bahkali | 2010 | Agricultural Sciences in China2010,9,5: | 14 |
| 3 | What is the quantitative risk of gastric cancer in the first-degree relatives of patients? A meta-analysis显示文摘AIM To quantify the risk of gastric cancer in first-degree relatives of patients with the cancer. METHODS A comprehensive literature search was performed. Case-control trials comparing the frequency of a positive family history of gastric cancer in patients with gastric cancer, vs non-gastric cancer controls were retrieved. Studies with missed or non-extractable data, studies in children, abstracts, and duplicate publications were excluded. A meta-analysis of pooled odd ratios was performed using Review Manager 5.0.25. We performed subgroup analysis on Asian studies and a sensitivity analysis based on the quality of the studies, type of the outcome, sample size, and whether studies considered only first-degree relatives. RESULTS Thirty-two relevant studies out of 612 potential abstracts(n = 80690 individuals) were included. 19.0% of the patients and 10.9% of the controls had at least one relative with gastric cancer(P < 0.00001). The pooled relative risk for the development of gastric cancer in association with a positive family history was 2.35(95%CI: 1.96-2.81). The Cochran Q test for heterogeneity was positive(P < 0.00001, I 2 = 92%). After excluding the three outlier studies with the highest relative risks, heterogeneity remained significant(P < 0.00001, I 2 = 90%). The result was not different among Asian studies as compared to others and remained robust in several sensitivity analyses. In the 26 studies which exclusively analysed the history of gastric cancer in first-degree relatives, the relative risk was 2.71(95%CI: 2.08-3.53; P < 0.00001). CONCLUSION Individuals with a first-degree relative affected with gastric cancer have a risk of about 2.5-fold for the development of gastric cancer. This could be due to genetic or environmental factors. Screening and preventive strategies should be developed for this highrisk population. | Mohammad Yaghoobi Julia McNabb-Baltar Raheleh Bijarchi Richard H Hunt | 2017 | World Journal of Gastroenterology2017,23,13: | 13 |
| 4 | Personality factors and profiles in variants of irritable bowel syndrome显示文摘AIM: To study the association between irritable bowel syndrome (IBS) variants (constipation,diarrhea,or both) and personality traits in non-psychiatric patients. METHODS: IBS was diagnosed using the Rome Ⅱ diagnostic criteria after exclusion of organic bowel pathology. The entry of each patient was confirmed following a psychiatric interview. Personality traits and the score of each factor were evaluated using the NEO Five Factor Inventory. RESULTS: One hundred and fifty patients were studied. The mean age (± SD) was 33.4 (± 11.0) year (62% female). Subjects scored higher in neuroticism (26.25 ± 7.80 vs 22.92 ± 9.54,P < 0.0005),openness (26.25 ± 5.22 vs 27.94 ± 4.87,P < 0.0005) and conscientiousness (32.90 ± 7.80 vs 31.62 ± 5.64,P < 0.01) compared to our general population derived from universities of Iran. Our studied population consisted of 71 patients with Diarrhea dominant-IBS,33 with Constipation dominant-IBS and 46 with Altering type-IBS. Scores of conscientiousness and neuroticism were significantly higher in C-IBS compared to D-IBS and A-IBS (35.79 ± 5.65 vs 31.95 ± 6.80,P = 0.035 and 31.97 ± 9.87,P = 0.043,respectively). Conscientiousness was the highest dimension of personality in each of the variants. Patients with C-IBS had almost similar personality profiles,composed of higher scores for neuroticism and conscientiousness,with low levels of agreeableness,openness and extraversion that were close to those of the general population. CONCLUSION: Differences were observed between IBS patients and the general population,as well as between IBS subtypes,in terms of personality factors. Patients with constipation-predominant IBS showed similar personality profiles. Patients with each subtype of IBS may benefit from psychological interventions,which can be focused considering the characteristics of each subtype. | Alireza Farnam Mohammad H Somi Firouz Sarami Sara Farhang Sanaz Yasrebinia | 2007 | World Journal of Gastroenterology2007,13,47: | 10 |

| 10 | Phase-field modeling of void evolution and swelling in materials under irradiation显示文摘Void swelling is an important phenomenon observed in both nuclear fuels and cladding materials in operating nuclear reactors. In this work we develop a phase-field model to simulate void evolution and void volume change in irradiated materials. Important material processes, including the generation of defects such as vacancies and self-interstitials, their diffusion and annihilation, and void nucleation and evolution, have been taken into account in this model. The thermodynamic and kinetic properties, such as chemical free energy, interfacial energy, vacancy mobility, and annihilation rate of vacancies and interstitials, are expressed as a function of temperature and/or defect concentrations in a general manner. The model allows for parametric studies of critical void nucleus size, void growth kinetics, and void volume fraction evolutions. Our simulations demonstrated that void swelling displays a quasi-bell shape distribution with temperature often observed in experiments. | HENAGER Charles H Jr KHALEEL Mohammad | 2011 | Science China(Physics,Mechanics & Astronomy)2011,54,5: | 3 |
| 11 | Endoscopic retrograde cholangiopancreatography outcome from a single referral center in Iran显示文摘BACKGROUND: Endoscopic retrograde cholangiopancreato- graphy (ERCP) is the first choice for diagnostic evaluation of the pancreatic and biliary tree and can be accompanied by a high diagnostic sensitivity and a poor therapeutic outcome. In the current study, we described our experiences in the indications, findings, and technical success of ERCP in a sample of the Iranian population admitted to a referral center in Iran. METHODS: In a retrospective review database-based study, 780 patients (393 males and 387 females; mean age 57.5 years) who had undergone diagnostic and therapeutic ERCP with the primary diagnosis of hepatobiliary disorder between 2006 and 2008 at Taleghani Hospital in Tehran were reviewed. The key data were demographic characteristics, clinical information, laboratory parameters, as well as post-ERCP complications. RESULTS: A history of cholecystectomy was found in about one-third (36.3%) of participants and 80 (10.3%) out of 780 patients had a previous history of biliary stone. A minority (1.4%) of the patients suffered from hepatobiliary carcinomas, and 11 patients had cirrhosis. The most common clinical manifestations in the patients undergoing diagnostic ERCP were icterus (47.3%), weight loss (31.2%), and dark urine (26.9%). Selective biliary cannulation was technically successful in 87.0% of the patients; however, cannulation failed in 13.0%. The most frequent final diagnosis of ERCP was common bile duct stone that was detected in 40.1% of the patients. The ERCP results in 11.0% of the patients were normal. Regarding appropriate treatment, successful stenting was performed in 43 patients (15.2%). Among post-ERCP complications, pancreatitis was the most adverse event withan incidence rate of 3.3%. Other complications including local bleeding, cholangitis and gastrointestinal perforation, rarely occurred. Post-ERCP pancreatitis was reported in 1.8% of men and 3.6% of women (P=0.120). Pancreatitis was more common in women below 70 years than in those who were older than 70 years (3.6% versus 0.5%; OR: 8.216, P=0.015). This might be due to the more functionally active pancreas in younger women than in the older ones. However, other complications were similar in the two age groups. CONCLUSIONS: Based on our experience, ERCP indications, final diagnosis and related complications are comparatively consistent with those reported in other countries. The most common post-ERCP complication is pancreatitis that is more often observed in younger patients. | Amir H Mohammad Alizadeh Esmaeil S Afzali Mirhadi Mousavi Yaghoub Moaddab Mohammad R Zali | 2010 | Hepatobiliary & Pancreatic Diseases International2010,9,4: | 3 |
| 12 | Nanoscopy reveals surface-metallic black phosphorus显示文摘Black phosphorus(BP)is an emerging two-dimensional material with intriguing physical properties.It is highly anisotropic and highly tunable by means of both the number of monolayers and surface doping.Here,we experimentally investigate and theoretically interpret the near-field properties of a-few-atomic-monolayer nanoflakes of BP.We discover near-field patterns of bright outside fringes and a high surface polarizability of nanofilm BP consistent with its surface-metallic,plasmonic behavior at mid-infrared frequencies o1176 cm−1.We conclude that these fringes are caused by the formation of a highly polarizable layer at the BP surface.This layer has a thickness of~1 nm and exhibits plasmonic behavior.We estimate that it contains free carriers in a concentration of n≈1.1×10^(20) cm^(−3).Surface plasmonic behavior is observed for 10–40 nm BP thicknesses but absent for a 4-nm BP thickness.This discovery opens up a new field of research and potential applications in nanoelectronics,plasmonics and optoelectronics. | Yohannes Abate Sampath Gamage Zhen Li Viktoriia Babicheva Mohammad H Javani Han Wang Stephen B Cronin Mark I Stockman | 2016 | Light(Science & Applications)2016,5,1: | 2 |

| 15 | Predicting groundwater level of wells in the Diyala River Basin in eastern Iraq using artificial neural network显示文摘Al-Mansourieh zone is a part of Al-Khalis City within the province of Diyala and located in the Diyala River Basin in eastern Iraq with a total area about 830 km2.Groundwater is the main water source for agriculture in this zone.Random well drilling without geological and hydraulic information has led the most of these wells to dry up quickly.Therefore,it is necessary to estimate the levels of groundwater in wells through observed data.In this study,Alyuda NeroIntelligance 2.1 software was applied to predict the groundwater levels in 244 wells using sets of measured data.These data included the coordinates of wells(x,y),elevations,well depth,discharge and groundwater levels.Three ANN structures(5-3-3-1,5-10-10-1 and 5-11-11-1)were used to predict the groundwater levels and to acquire the best matching between the measured and ANN predicted values.The coefficient of correlation,coefficient determination(R2)and sum-square error(SSE)were used to evaluate the performance of the ANN models.According to the ANN results,the model with the three structures has a good predictability and proves more effective for determining groundwater level in wells.The best predictor was achieved in the structure 5-3-3-1,with R2 about 0.92,0.89,0.84 and 0.91 in training,validation,testing and all processes respectively.The minimum average error in the best predictor is achieved in validation and testing processes at about 0.130 and 0.171 respectively.On the other hand,the results indicated that the model has the potential to determine the appropriate places for drilling the wells to obtain the highest level of groundwater. | Abdulrahman Th Mohammad Qassem H Jalut Nadia L Abbas | 2020 | Journal of Groundwater Science and Engineering2020,8,1: | 2 |
