2Overview of cytokines and nitric oxide involvement in immuno-pathogenesis of inflammatory bowel diseases显示文摘Inflammatory bowel diseases(IBDs), including Crohn's disease and ulcerative colitis are complex disorders with undetermined etiology. Several hypotheses suggest that IBDs result from an abnormal immune response against endogenous flora and luminal antigens in genetically susceptible individuals. The dysfunction of the mucosal immune response is implicated in the pathogenesis of IBD. The balance between pro-inflammatory cytokines [tumor necrosis factor(TNF)-α, interleukin(IL)-1b, IL-8, and IL-17A], anti-inflammatory cytokines(IL-4 and IL-13), and immunoregulatory cytokines(IL-10 and transforming growth factors b) is disturbed. Moreover, evidence from animal and clinical studies demonstrate a positive correlation between an increased concentration of nitric oxide(NO) and the severity of the disease. Interestingly, proinflammatory cytokines are involved in the up-regulation of inducible oxide synthase(iN OS) expression in IBD. However, anti-inflammatory and immunoregulatory cytokines are responsible for the negative regulation of iN OS. A positive correlation between NO production and increased pro-inflammatory cytokine levels(TNF-α, IL-6, IL-17, IL-12, and interferon-γ) were reported in patients with IBD. This review focuses on the role of cytokines in intestinal inflammation and their relationship with NO in IBD.Imene Soufli Ryma Toumi Hayet Rafa Chafia Touil-Boukoffa 2016World Journal of Gastrointestinal Pharmacology and Therapeutics2016,7,3:30
3Phenolic and flavonoid contents, antioxidant and antimicrobial activities of leaf extracts from ten Algerian Ficus carica L. varieties显示文摘Objective: To determine the total phenolic and flavonoid contents, antioxidant and antimicrobial activities of methanolic leaf extracts of ten Algerian fig(Ficus carica L.)varieties(uniferous, biferous and caprifig tree).Methods: Phenolics were extracted by Soxhlet method and analyzed by the Folin–Ciocalteu colorimetric method. Flavonoids were determined by aluminum trichloride assay and the antioxidant capacity was determined by the 2,2-diphenyl-1-picrylhydrazyl radical scavenging assay. The antimicrobial activity was studied with the disc diffusion method and a macrodilution broth method was used to determine the minimal inhibitory concentrations and minimal lethal concentrations.Results: The mean extract yield was 14.10% ± 0.66%(n = 10). Leaf extract of biferous followed by uniferous varieties had the highest total phenolic contents [(52.296 ± 5.232)and(48.973 ± 2.015) mg gallic acid equivalent/g of dry plant extract respectively], flavonoids [(14.388 ± 0.333) and(14.136 ± 1.082) mg quercetin equivalent/g of dry plant extract] and antioxidant capacity [IC50(798.754 ± 108.590) and(825.004 ± 110.835) mg/m L]. Antioxidant capacity of fig leaves was significantly correlated with phenolic contents(r = 0.748). These extracts showed bactericidal activity and moderate antifungal activity, and the minimal inhibitory concentrations and minimal lethal concentrations were determined on Bacillus cereus and Staphylococcus aureus.Conclusions: All tested extracts contain phenolic compounds and exhibited an antioxidant activity and an antimicrobial effect against Gram-positive and Gram-negative bacteria. Further researches on identification and purification of phenolic compounds are required.Souhila Mahmoudi Mustapha Khali Abderahim Benkhaled Karima Benamirouche Imen Baiti 2016Asian Pacific Journal of Tropical Biomedicine2016,6,3:17

7Cytokine and apoptosis gene polymorphisms influence the outcome of hepatitis C virus infection显示文摘BACKGROUND:Hepatitis C virus (HCV) infection is thought to be chronic and the factors leading to viral clearance or persistence are poorly understood.This study was undertaken to investigate the possibility of a significant relationship between the spontaneous clearance or the persistence of hepatitis C virus (HCV) infection and cytokine and apoptosis gene polymorphisms in Tunisian patients on hemodialysis.METHODS:Polymorphisms of the genes IL-1 (-889 IL-1α,-511 and +3954 IL-1β,IL-1Ra),IL-18 (-137 and-607),IL-12 (-1188) and Apo1/Fas (-670) were determined by PCR-RFLP,PCR-SSP and PCR-VNTR in 100 healthy blood donors and 100 patients infected with HCV and undergoing hemodialysis.The patients were classified into two groups:G1 consisted of 76 active chronic hepatitis patients (positive for HCV RNA) and G2 consisted of 24 hemodialysed patients who spontaneously eliminated the virus (negative for HCV RNA).RESULTS:The frequency of genotype association [-137GC/-607CA] IL-18 was higher in G2 (41.7%) than in G1 (15.8%) (P=0.008;OR=0.26;95% CI,0.10-0.73).We also found a higher frequency of the AA genotype of the Apo1/Fas gene in G2 (41.6%) than in G1 (17.5%) (P=0.026;OR=3.49;95% CI,1.13-10.69).Adjustment for known covariate factors (age,gender and genotype) confirmed these univariate findings and revealed that the genotype association GC-CA of the (-137 and-607) IL-18 gene and the AA genotype of the Apo1/Fas gene were associated with the clearance of HCV (P=0.041 and 0.017,respectively).CONCLUSION:The two genotypes GC-CA of the (-137 and-607) IL-18 polymorphism and the AA genotype of the Apo1/Fas gene influence the outcome of HCV infection in Tunisian patients on hemodialysis.Leila Ksiaa Cheikhrouhou Imen Sfar Hajer Aounallah-Skhiri Houda Aouadi Salwa Jendoubi-Ayed Taieb Ben Abdallah Khaled Ayed Yousr Lakhoua-Gorgi 2011Hepatobiliary & Pancreatic Diseases International2011,10,3:4
8Robust Neural Control of Discrete Time Uncertain Nonlinear Systems Using Sliding Mode Backpropagation Training Algorithm显示文摘This work deals with robust inverse neural control strategy for a class of single-input single-output(SISO) discrete-time nonlinear system affected by parametric uncertainties. According to the control scheme, in the first step, a direct neural model(DNM)is used to learn the behavior of the system, then, an inverse neural model(INM) is synthesized using a specialized learning technique and cascaded to the uncertain system as a controller. In previous works, the neural models are trained classically by backpropagation(BP) algorithm. In this work, the sliding mode-backpropagation(SM-BP) algorithm, presenting some important properties such as robustness and speedy learning, is investigated. Moreover, four combinations using classical BP and SM-BP are tested to determine the best configuration for the robust control of uncertain nonlinear systems. Two simulation examples are treated to illustrate the effectiveness of the proposed control strategy.Imen Zaidi Mohamed Chtourou Mohamed Djemel 2019International Journal of Automation and computing2019,16,2:4
9Association of Fas/Apo1 gene promoter (-670 A/G) polymorphism in Tunisian patients with IBD显示文摘AIM: To detect a possible association between the polymorphism of the (-670 A/G) Fas/Apo1 gene promoter and susceptibility to Crohn's disease (CD) and ulcerative colitis (UC) in the Tunisian population. METHODS: The (-670 A/G) Fas polymorphism was analyzed in 105 patients with CD, 59 patients with UC, and 100 controls using the polymerase chain reaction restriction fragment length polymorphism method. RESULTS: Significantly lower frequencies of the Fas -670 A allele and A/A homozygous individuals were observed in CD and UC patients when compared with controls. Analysis of (-670 A/G) Fas polymorphism with respect to sex in CD and UC showed a significant difference in A/A genotypes between female patients and controls (P corrected = 0.004 in CD patients and P corrected = 0.02 in UC patients, respectively). Analysis also showed a statistically significant association between genotype AA of the (-670 A/G) polymorphism and the ileum localization of the lesions (P corrected = 0.048) and between genotype GG and the colon localization (Pcorrected = 0.009). The analysis ofinflammatory bowel disease patients according to clinical behavior revealed no difference. CONCLUSION: Fas-670 polymorphism was associated with the development of CD and UC in the Tunisian population.Walid Ben Aleya Imen Sfar Leila Mouelhi Houda Aouadi Mouna Makhlouf Salwa Ayed-Jendoubi Samira Matri Azza Filali Taoufik Najjar Taeib Ben Abdallah Khaled Ayed Yousr Gorgi 2009World Journal of Gastroenterology2009,15,29:3
10Association of hepatitis C virus infection and diabetes in central Tunisia显示文摘AIM:To investigate hepatitis C virus(HCV) seroprevalence in Tunisian patients with diabetes mellitus and in a control group.METHODS:A cross-sectional study was conducted to determine the HCV seroprevalence in 1269 patients with diabetes(452 male,817 female) and 1315 nondiabetic patients,attending health centers in Sousse,Tunisia.HCV screening was performed in both groups using a fourth-generation enzyme immunoassay.RESULTS:In the diabetic group,17(1.3%) were found to be HCV-infected compared with eight(0.6%) in the control group,although the difference was not significant(P=0.057).Quantitative PCR was performed in 20 patients.Eleven patients were positive and showed HCV genotype 1b in all cases.CONCLUSION:Frequency of HCV antibodies was low in patients with diabetes and in the control group in central Tunisia,with no signifi cant difference between the groups.Naoufel Kaabia Elhem Ben Jazia Ines Slim Imen Fodha Wissem Hachfi Rafika Gaha Mabrouk Khalifa Aoutef Hadj Kilani Halim Trabelsi Ahmed Abdelaziz Fethi Bahri Amel Letaief 2009World Journal of Gastroenterology2009,15,22:2
11Comprehensive review of autoantibodies in patients with hyper-IgM syndrome显示文摘Hyper-immunoglobulin M syndrome is an X-linked primary immunodeficiency disease caused by mutations in the CD40 ligand gene.The CD40 ligand has been recently highlighted as playing a key role in the pathogenesis of primary biliary cholangitis.In the present study,we assessed an extensive set of serum autoantibodies in a series of well-defined patients with hyper-immunoglobulin M syndrome.Serum,liver-related and liver-not-related autoantibodies IgG,IgM and IgA were tested by ELISA and standard indirect immunofluorescence in HEp-2 cells in 13 Tunisian patients(8 males and 5 females,aged 1–12 years)with hyper-immunoglobulin M syndrome during 1995–2012 and,as controls,21 age-and gender-matched blood donors.The level of IgM antibody against MIT3 was significantly higher in patients than in controls(35.8 vs 10.7,P=0.002).Half of the hyperimmunoglobulin M syndrome patients were found to be anti-MIT3 IgM positive vs none of the controls(Po0.0001).Twenty-three percent of patients were found to be anti-sp100 antibody positive vs only 0.05%of controls.By immunofluorescence,92.3%of patients were MIT3 IgM positive vs none of the controls.In conclusion,the IgM class of anti-MIT3 antibodies was shown to be present by both ELISA and immunofluorescence in most of the patients with hyper-immunoglobulin M syndrome.The presence of the hallmark of primary biliary cholangitis,a disease where the CD40 ligand is a key player,in an immunodeficiency disease caused by mutations in the CD40 ligand gene is very intriguing and opens new scenarios in understanding the immune pathogenesis of primary biliary cholangitis.Mohamed-Ridha Barbouche Qubo Chen Marco Carbone Imen Ben-Mustapha Zakera Shums Mehdi Trifa Federica Malinverno Francesca Bernuzzi Haiyan Zhang Nourhen Agrebi Gary L Norman Christopher Chang M Eric Gershwin Pietro Invernizzi 2018Cellular & Molecular Immunology2018,15,6:2
12Characterization of Tunisian marine sediments in Rades and Gabes harbors显示文摘The objective of this article is to study the geotechnical and environmental characteristics of sediments dredged from two Tunisian harbors:Rades and Gabes.The first harbor represents the main facility place in the national transport chain.The second one is selected as its sediments present a serious ecological constraint caused by the discharge of wastes into the marine environment.These sediments are either discarded at sea or landfilled despite their harmful effects on the environment.The article is divided into three main sections.The first one presents the material that was carried for Rades and Gabes harbors.The conservation conditions and the used experimental tests are detailed.Geotechnical characterization includes the determination of the grain size distribution,the water content,the Atterberg limits,the methylene blue value,the specific area,the bulk density,the specific unit weight,the organic and carbonate contents.Environmental characterization is assessed by the determination of metals concentrations in a leaching solution.The second section deals with the description and analysis of geotechnical properties of Rades and Gabes harbors' sediments.The results obtained show that Rades harbor sediments are slightly sandy clayey silts whereas Gabes harbor sediments are silty sands characterized by a highly plastic clay fraction.Both of the two sediments don't exhibit a high organic content.Finally,chemical,mineralogical and environmental properties are presented and then analysed.The experimental results obtained show that Rades and Gabes sediments could be used as a sand substitute in the formulation of a new construction material.Gabes harbor sediments are more polluted than Rades harbor sediments.Imen BEL HADJ ALI Zoubeir LAFHAJ Mounir BOUASSIDA Imen SAID 2014International Journal of Sediment Research2014,29,3:2
13Natural evolution of hepatitis C virus infection in hemodialysis Tunisian patients and CTLA-4 SNP's显示文摘AIM: To analyze the polymorphisms of CTLA-4 gene involved in the response against hepatitis C virus(HCV) infection.METHODS: We recruited 500 hemodialysed patients from several hemodialysis centers, all HCV-antibody positive, spread over different regions of Tunisia, as part of a national survey in 2008 conducted in the laboratory of immunology at the Charles Nicolle hospital Tunisia, classified into two groups G1(PCR+) and G2(PCR-) according to the presence or absence of viral RNA. Of these patients, 307 were followed prospectively on a viral molecular level over a period from 2002 to 2008, divided into two groups based on the persistence and viral clearance. PCR-RFLP was performed for the analysis of SNPs(+49) A/G and(+6230) G/A CTLA-4 for these 500 patients and 358 healthy controls.RESULTS: Analysis of clinical and virological charac-teristics of our cohort suggests a nosocomial infection in our hemodialysed patients with transfusion history as a primary risk factor and a predominance of genotype 1b. The haplotype analysis revealed an increase of frequencies of GG(+49)/(CT60) CTLA-4 in the entire patients group compared to controls(P = 0.0036 and OR = 1.42; 95%CI: 1.12-1.79, respectively). This haplotype is therefore associated with susceptibility to HCV infection. CONCLUSION: Our study suggests a possible role of CTLA-4 polymorphisms in the outcome of HCV infection in the Tunisian hemodialysed population.Leila Ksiaa Cheikhrouhou Yousr Lakhoua-Gorgi Imen Sfar Salwa Jendoubi-Ayed Houda Aouadi Mouna Makhlouf Khaled Ayed Taieb Ben Abdallah 2015World Journal of Gastroenterology2015,21,35:2
