| 1 | Persistent alanine aminotransferase elevation among the general Iranian population: Prevalence and causes显示文摘AIM: To determine the prevalence and causes of persistently elevated alanine aminotransferase (ALT) levels among the general population in northern Iran. METHODS: A total of 2292 (1376 female, aged 18-75 year), were selected by systematic clustered random sampling from the cities and villages of Gonbad and Kalaleh in Golestan Province and invited to participate in the study. A comprehensive history regarding alcohol drinking and medication was taken. Body mass index (BMI), viral markers and ALT levels were measured. If ALT level was ≥ 40 U/L, it was rechecked twice within 6 mo. Those with ≥ 2 times elevation of ALT were considered as having persistently elevated ALT level. Non-alcoholic fatty liver disease (NAFLD) was diagnosed based on evidence of fatty liver upon sonography and excluding other etiology. RESULTS: A total of 2049 (1351 female) patients participated in the study, 162 (7.9%) had elevated ALT level at the first measurement. Persistently elevated ALT level was detected in 64 (3.1%) participants, with51 (79.6%) with no obvious etiology, six (9.3%) with Hepatitis B, four (6.2%) with Hepatitis C virus (HCV) infection and three (4.6%) with alcoholic hepatitis. The prevalence of NAFLD and alcoholic hepatitis was 2.04% (42 patients) and 0.1% (three), respectively. There was correlation between NAFLD and male gender, overweight, diabetes and living in an urban area [odds ratio = 3.03 (95% CI: 1.6-5.72), 4.21 (95% CI: 1.83-9.68), 2.86 (95% CI: 1.05-7.79) and 2.04 (95% CI: 1.00-4.16) respectively]. CONCLUSION: NAFLD is the most common cause of persistently elevated serum ALT level among the general population of Iran. | Raika Jamali Mahmoodreza Khonsari Shahin Merat Masoud Khoshnia Elham Jafari Alireza Bahram Kalhori Hassan Abolghasemi Sedighe Amini Mahtab Maghsoudlu Mohammad Reza Deyhim Houri Rezvan Akram Pourshams | 2008 | World Journal of Gastroenterology2008，14，18： | 7 |
| 2 | Insights in hydrodynamics of bubbling fluidized beds at elevated pressure by DEM-CFD approach显示文摘A numerical simulation was conducted to study the effect of pressure on bubble dynamics in a gas-solid fluidized bed.The gas flow was modeled using the continuum theory and the solid phase,by the dis-crete element method(DEM).To validate the simulation results,calculated local pressure fluctuations were compared with corresponding experimental data of 1-mm polyethylene particles.It was shown that the model successfully predicts the hydrodynamic features of the fluidized bed as observed in the experiments.Influence of pressure on bubble rise characteristics such as bubble rise path,bubble sta- bility,average bubbles diameter and bubble velocity through the bed was investigated.The simulation results are in conformity with current hydrodynamic theories and concepts for fluidized beds at high pressures.The results show further that elevated pressure reduces bubble growth,velocity and stability and enhances bubble gyration through the bed,leading to change in bed flow structure. | Zahra Mansourpour Sedighe Karimi Reza Zarghami Navid Mostoufi Rahmat Sotudeh-Gharebagh | 2010 | Particuology2010，8，5： | 5 |
| 3 | A Fault Tolerant Control Scheme Using the Feasible Constrained Control Allocation Strategy显示文摘This paper investigates the necessity of feasibility considerations in a fault tolerant control system using the constrained control allocation methodology where both static and dynamic actuator constraints are considered. In the proposed feasible control allocation scheme, the constrained model predictive control(MPC) is employed as the main controller. This considers the admissible region of the control allocation problem as its constraints. Using the feasibility notion in the control allocation problem provides the main controller with information regarding the actuator′s status, which leads to closed loop system performance improvement. Several simulation examples under normal and faulty conditions are employed to illustrate the effectiveness of the proposed methodology. The main results clearly indicate that closed loop performance and stability characteristics can be significantly degraded by neglecting the actuator constraints in the main controller. Also, it is shown that the proposed strategy substantially enlarges the domain of attraction of the MPC combined with the control allocation as compared to the conventional MPC. | Mehdi Naderi Tor Arne Johansen Ali Khaki Sedigh | 2019 | International Journal of Automation and computing2019，16，5： | 2 |

| 11 | Predictors of readiness for discharge in mothers of preterm infants: The role of stress, self-efficacy and perceived social support显示文摘Objective:To determine the predictive role of stress,self-efficacy,and perceived social support on readiness for discharge in mothers of preterm infants.Methods:The present cross-sectional,descriptive-analytical study was conducted on 120 mothers of preterm infants admitted to hospitals affiliated to Lorestan University of Medical Sciences,Iran in 2019.Participants were selected by a convenience sampling method and based on inclusion criteria.Data collection tools included the demographic questionnaire of mothers and infants,parent perceptions of their child's hospital discharge,parental stressor scale:neonatal intensive care unit,perceived maternal parenting,and multidimensional scale of perceived social support.Data were analyzed using Pearson correlation and stepwise regression at the significance level of 0.05.Results:Infant behavior and appearance,situational belief,and family support achieved the highest mean score from parents'stress,self-efficacy,and perceived social support dimensions,respectively.There was a significant relationship between stress,self-efficacy,and perceived social support with readiness for discharge in mothers of preterm infants(P<0.001).The score of mothers'readiness for discharge decreased by 0.07 per 1-point increase in stress score,and the score of readiness for discharge in mothers of preterm infants rose by 0.35 and 0.43,respectively,for a unit increase in the scores of self-efficacy and perceived social support.Conclusions:Stress,self-efficacy,and perceived social support can be considered as predictors of readiness for discharge in mothers of preterm infants.It is suggested that nurses in neonatal intensive care units provide a better platform for the readiness for discharge in mothers of preterm infants by reducing stressors and increasing maternal self-efficacy and social support. | Sedighe Valipour Fatemeh Estebsari Maliheh Nasiri Parvaneh Vasli | 2022 | Asian pacific Journal of Reproduction2022，11，6： | 1 |
