| 1 | 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 |
| 2 | Liver trauma: What current management?显示文摘Background: The liver is the most commonly damaged organ in abdominal trauma. The management of liver trauma has experienced many changes over the last two decades. Currently there is a trend toward a non-operative treatment warranted by the successful pediatric experience and better results recorded in many trauma centers worldwide. This study aimed to evaluate outcomes of operative and non-operative management of liver trauma in our institution over the last five years.Methods: The patients with a diagnosis of blunt or penetrating liver injuries, admitted and managed in our hospital from January 2012 to December 2016 were retrospectively studied. The patients were divided into 2 groups, operated and non-operated groups, according to the initial management considered appropriate at the time of patient admission. Clinical features and outcomes were analyzed.Results: The study involved 83 patients, with a mean age of 33 years and a marked male predominance(85.5%). The most common type of lesions was blunt trauma and the main cause was road traffic accidents. Sixty-eight liver injuries(81.9%) were of low severity(grades Ⅰ,Ⅱ,Ⅲ), while 15(18.1%) were of high severity(grade Ⅳ or greater). Fifty-six patients(67.5%) had multiple injuries. Surgical treatment was performed in 26(31.3%) patients. Non-operative management was undertaken in 57 cases(68.7%). The morbidity and mortality rates were clearly lower in non-operative patients compared to those in the operated group.Conclusions: Careful non-operative management is an adequate therapeutic strategy for the patients suffering from liver trauma with stable hemodynamics. Patients with complex hepatic trauma and especially those with other organ injuries continue to have significantly higher mortality. | Mohamed Tarchouli Mohamed Elabsi Noureddine Njoumi Mohamed Essarghini Mahjoub Echarrab Mohamed Rachid Chkoff | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，1： | 4 |

| 4 | Chronic exercise training versus acute endurance exercise in reducing neurotoxicity in rats exposed to lead acetate显示文摘After intraperitoneal injection of 20 mg/kg lead acetate,rats received 8 weeks of treadmill exercise (15-22 m/min,25-64 minutes) and/or treadmill exercise at 1.6 km/h until exhaustion.The markers related to neurotoxicity were measured by enzyme-linked immunosorbent assay method.8 weeks of treadmill exercise significantly increased brain-derived neurotrophic factor level in the hippocampus (P=0.04) and plasma level of total antioxidant capacity of rats exposed to lead acetate (P < 0.001),and significantly decreased plasma level of malondialdehyde (P < 0.001).Acute exercise only decreased the hippocampal malondialdehyde level (P=0.09) and increased brain-derived neurotrophic factor level in the hippocampus (P=0.66).Acute exercise also enhanced the total antioxidant capacity in rats exposed to lead acetate,insignificantly (P=0.99).These findings suggest that chronic treadmill exercise can significantly decrease neurotoxicity and alleviate oxidative stress in rats exposed to lead acetate.However,acute endurance exercise was not associated with these beneficial effects. | Mohammad Shahandeh Valiollah Dabidi Roshan Somayeh Hosseinzadeh Soleiman Mahjoub Vaginak Sarkisian | 2013 | Neural Regeneration Research2013，8，8： | 3 |
| 5 | Second-order Sliding Mode Approaches for the Control of a Class of Underactuated Systems显示文摘In this paper, first-order and second-order sliding mode controllers for underactuated manipulators are proposed. Sliding mode control(SMC) is considered as an effective tool in different studies for control systems. However, the associated chattering phenomenon degrades the system performance. To overcome this phenomenon and track a desired trajectory, a twisting, a supertwisting and a modified super-twisting algorithms are presented respectively. The stability analysis is performed using a Lyapunov function for the proposed controllers. Further, the four different controllers are compared with each other. As an illustration, an example of an inverted pendulum is considered. Simulation results are given to demonstrate the effectiveness of the proposed approaches. | Sonia Mahjoub Faical Mnif Nabil Derbel | 2015 | International Journal of Automation and computing2015，12，2： | 2 |
