| 1 | High prevalence of multidrug-resistance in Acinetobacter baumannii and dissemination of carbapenemase-encoding genes bla_(OXA-23-like),bla_(OXA-24-like)and bla_(NDM-1) in Algiers hospitals显示文摘Objective:To assess and characterize antibiotic resistance in Acinetobacter baumannii strains recovered from 5 health-care facilities in Algiers.Methods:Antibiotic susceptibility testing was performed by agar diffusion and agar dilution methods,resistance genes were identified by PCR and sequencing,and molecular typing of isolates was carried out by enterobacterial repetitive intergenic consensus-PCR(ERIC-PCR).Results:Among 125 tested isolates,117(93.6% ) were multidrug-resistant.of which 94(75.2% ) were imipenem resistant.The bla_(ADC)and bla_(OXA-51-like) genes were detected in all isolates,in association with ISAba I sequence in 84% and 8% (imipenem resistant) of isolates,respectively.The bla_(OXA-23-like) and bla_(OXA-24-like)carbapenemase genes were delected in 67.02% and 20.21% of imipenem-resistant isolates,respectively.The bla_(OXA-23-like) gene is linked to ISAba1 or ISAba4 elements.The metallo-β-lactamase NDM-1 gene was found in 10(10.6% ) imipenem-resisianl strains from three hospitals,it is linked to ISAba125 clement in nine strains.Extended spectrum β-lactamases production was not detected.Imipenem and cefotaxime resistance phenolypes could not be transferred to Escherichia coli by conjugation.Outer membrane protein CarO gene was not delected in four imipenem-resisianl isolates.The aac(6')-1b.sul1,sul2,tetA and tetB genes were present in 5.31% .36.17% .77.65% .1.06% and 65.92% of strains,respectively.Class 1 integrons were detected in 23.4% strains.KRIC-PCR typing showed a genetic diversity among bla_(OXA-23-like) and bla_(OXA-24-like) positive strains,while clonality was observed among bla_(NDM-1)positives.Conclusions:This study highlighted the high prevalence of imipenem resistance in Acinetobacter baumannii in Algiers hospitals mediated mainly by bla_(OXA-23-like),bla_(OXA-24-like),and bla_(NDM-1) genes. | Khadidja Khorsi Yamina Messai Moufida Hamidi Houria Ammari Rabah Bakour | 2015 | Asian Pacific Journal of Tropical Medicine2015，8，6： | 20 |
| 2 | Role of relevant immune-modulators and cytokines in hepatocellular carcinoma and premalignant hepatic lesions显示文摘AIM To assess the levels of different immune modulators in patients with hepatocellular carcinoma(HCC),in relation to other hepatic diseases.METHODS Eighty-eight patients were included in the current study and represented patients with HCC(20),liver cirrhosis(28) and chronic hepatitis(CH;25),and normal controls(NC;15).Peripheral blood was isolated for immunophenotyping of active myeloid dendritic cells(m DCs;CD1 c and CD40),mature inactive myeloid cells(CD1 c and HLA),active plasmacytoid cells(p DCs;CD303 and CD40),mature inactive p DCs(CD30 and HLA),active natural killer(NK) cells(CD56 and CD161),active NK cells(CD56 and CD314) and inactive NK cells(CD56 and CD158) was done by flow cytometry.Serum levels of interleukin(IL)-2,IL-10,IL-12,IL-1β,interferon(IFN)-α,IFN-γ and tumor necrosis factor(TNF)-αR2 were assessed by ELISA.RESULTS Active m DCs(CD1 C+/CD40+) and inactive m DCs(CD1 c+/HLA+) were significantly decreased in HCC patients in relation to NC(P < 0.001).CD40+ expression on active p DCs was decreased in HCC patients(P < 0.001),and its level was not significantly changed among other groups.Inactive p DCs(CD303+/HLA+),inactive NKs(CD56+/CD158+) and active NKs(CD56+/CD161+) were not statistically changed among the four groups studied;however,the latter was increased in CH(P < 0.05).NKG2 D was statistically decreased in HCC,CH and cirrhosis(P < 0.001),and it was not expressed in 63%(12/20) of HCC patients.There was significant decrease of IL-2,IFN-α and IFN-γ(P < 0.001),and a significant increase in IL-10,IL-1β,and TNF-αR2(P <0.01,P < 0.001 and P < 0.001;respectively) in HCC patients.There was inverted correlation between IL-12 and IL-1β in HCC(r =-0.565,P < 0.01),with a strong correlation between p DCs(CD303+/CD40+) and NKs(CD56+/CD161+;r = 0.512,P < 0.05) as well as inactive m DCs(CD1 c+/HLA+) and inactive NK cells(CD56+/CD158+;r = 0.945,P < 0.001).CONCLUSION NKG2 D,CD40,IL-2 and IL-10 are important modulators in the development and progression of HCC. | Abdel-Rahman N Zekri Somaya El Deeb Abeer A Bahnassy Abeer M Badr Mona S Abdellateif Gamal Esmat Hosny Salama Marwa Mohanad Ahmed Esam El-dien Shimaa Rabah Assmaa Abd Elkader | 2018 | World Journal of Gastroenterology2018，24，11： | 6 |
| 3 | Robust superhydrophobic polyurethane sponge functionalized with perfluorinated graphene oxide for efficient immiscible oil/water mixture, stable emulsion separation and crude oil dehydration显示文摘In recent years, graphene oxide(GO), prepared by the modified Hummers’ method, and its derivatives have become a focus of research owing to their outstanding physical and chemical properties and low cost. Drawing inspiration from the mussel protein,a facile and environmentally-friendly method was employed to fabricate superhydrophobic/superoleophilic reduced graphene oxide(rGO) derivative. The preparation comprises two steps: coating GO nanosheets with polydopamine(PDA) and subsequent reaction with 1H,1H,2H,2H-perfluorodecanethiol. Due to the excellent adhesive ability of PDA, the resulting f PDA modified rGO nanosheets(rGO-f PDA) were firmly immobilized onto polyurethane(PU) sponge skeleton by a simple drop-coating method. The as-prepared rGO-f PDA functionalized sponge exhibited superhydrophobic behavior with a water contact angle of 162°±2°, high organic adsorption capacity, recyclability and stable oil/water separation behavior under different acidic/alkaline conditions. Due to its facile fabrication technique and outstanding properties, the superhydrophobic-superoleophilic PU-rGOf PDA sponge holds great promise as an oil adsorbent for cleaning up large-scale pollution of oil and organic solvents, and dehydrating crude oil. | CAO Ning GUO JingYu BOUKHERROUB Rabah SHAO QingGuo ZANG XiaoBei LI Jin LIN XueQiang JU Hong LIU EnYang ZHOU ChaoFan LI HuiPing | 2019 | Science China(Technological Sciences)2019，62，9： | 6 |
| 4 | Efficient elimination of environmental pollutants through sorption-reduction and photocatalytic degradation using nanomaterials显示文摘With the rapid development of industrial,large amounts of different inorganic and organic pollutants are released into the natural environments.The efficient elimination of environmental pollutants,i.e.,photocatalytic degradation of persistent organic pollutants into nontoxic organic/inorganic chemicals,in-situ solidification or sorption-reduction of heavy metal ions,is crucial to protect the environment.Nanomaterials with large surface area,active sites and abundant functional groups could form strong surface complexes with different kinds of pollutants and thereby could efficiently eliminate the pollutants from the aqueous solutions.In this review,wemainly focused on the recent works about the synthesis of nanomaterials and their applications in the efficient elimination of different organic and inorganic pollutants from wastewater and discussed the interaction mechanism from batch experimental results,the advanced spectroscopy techniques and theoretical calculations.The adsorption and the photocatalytic reduction of organic pollutants and the sorption/reduction of heavy metal ions are generally considered as the mainmethods to decrease the concentration of pollutants in the natural environment.This review highlights anew way for the real applications of novel nanomaterials in environmental pollution management,especially for the undergraduate students to understand the recent works in the elimination of different kinds of inorganic and organic chemicals in the natural environmental pollution management. | Njud SAlharbi Baowei Hu Tasawar Hayat Samar Omar Rabah Ahmed Alsaedi Li Zhuang Xiangke Wang | 2020 | Frontiers of Chemical Science and Engineering2020，14，6： | 5 |
| 5 | With increasing trends of prostate cancer in the Saudi Arabia and Arab World: Should we start screening programs?显示文摘Incidence rate for prostate cancer in the Arab World is significantly lower than United States and Europe, it ranges from 5.5% to 39.2%. However, the incidence and the number of deaths is expected to increase. In Saudi Arabia, the crude incidence rate and age standardized incidence rate of prostate cancer are reported to be steadily increasing in between 2001-2008. Only two screening trials were attempted in 2001 and 2009 which yielded an incidence rate of 1.17% and 2.5% respectively. Men in the Arab world are sharing a common characteristic of poor knowledge and poor attitude towards prostate cancer examination and screening practices. They are ill-informed about the PSA test's strengths and drawbacks because the doctors are not talking to them about the importance of counselling. Men should be encouraged to do PSA testing before the age of 50 and till the age of 70 years. This could be achieved by enhancing their attitude and enriching the knowledge of the physicians towards PSA testing, harms and benefits, through shared decision making, which would increase men's knowledge scores, reduced their decisional conflict and promote greater involvement in decision making. | Mostafa A Arafa Danny M Rabah | 2017 | World Journal of Clinical Oncology2017，8，6： | 4 |

| 7 | Effectiveness of hepatitis B virus vaccination program in Egypt:Multicenter national project显示文摘AIM:To assess the effectiveness of hepatitis B virus(HBV) vaccination program among fully vaccinated children.METHODS:A national community based crosssectional study was carried out in 6 governorates representing Egypt. A total of 3600 children aged from 9 mo to 16 years who were fully vaccinated with HBV vaccine during infancy were recruited. Face to face interviews were carried out and sera were evaluated for hepatitis B surface antigen(HBsA g),anti-HBV core antibodies(total) and quantitative detection of hepatitis B surface antibody using enzyme linked immunoassays techniques. Samples positive to HBs Ag/anti-HBV core antibodies were subjected to quantitative HBV-DNA detection by real time polymerase chain reaction with 3.8 IU/L detection limit. RESULTS:Sero-protection was detected among 2059 children(57.2%) with geometric mean titers 75.4 ± 3.6 IU/L compared to 3.1 ± 2.1 IU/L among nonseroprotected children. Multivariate logistic analysis revealed that older age and female gender were the significant predicting variables for having non seroprotective level,with adjusted odds ratio 3.3,9.1and 14.2 among children aged 5 to < 10,10 to < 15 and ≥ 15 years respectively compared to those < 5 years and 1.1 among girls compared to boys with P < 0.01. HBs Ag was positive in 0.11% and breakthrough infection was 0.36% and 0.39% depending on positivity of anti-HBc and DNA detection respectively. The prevalence of HBV infection was significantly higher among children aged ≥ 7 years(0.59%) compared to 0.07% among younger children with odds ratio equal to 8.4(95%CI:1.1-64.2) and P < 0.01.The prevalence was higher among girls(0.48%) than boys(0.29%) with P > 0.05.

| 9 | Silicone/graphene oxide co-cross-linked aerogels with wide-temperature mechanical flexibility,super-hydrophobicity and flame resistance for exceptional thermal insulation and oil/water separation显示文摘Development of multifunctional and high-performance silicone aerogel is highly required for various promising applications.However,unstable cross-linking structure and poor thermal stability of silicone network as well as complicated processing restrict the practical use significantly.Herein,we report a facile and versatile ambient drying strategy to fabricate lightweight,wide-temperature flexible,super-hydrophobic and flame retardant silicone composite aerogels modified with low-content functionalized graphene oxide(FGO).After optimizing silane molecules,incorporation ofγ-aminopropyltriethoxysilane functionalization is found to promote the dispersion stability of GO during the hydrolysis-polymerization process and thus produce the formation of unique strip-like co-cross-linked network.Consequently,the aerogels containing∼2.0 wt%FGO not only possess good cyclic compressive stability under strain of 70%for 100 cycles and outstanding mechanical reliability in wide temperature range(from liquid nitrogen to 350℃),but also display excellent flame resistance and super-hydrophobicity.Further,the optimized silicone/FGO aerogels display exceptional thermal insulating performance superior to pure aerogel and hydrocarbon polymer foams,and they also show efficient oil absorption and separation capacity for var-ious solvents and oil from water.Clearly,this work provides a new route for the rational design and development of advanced silicone composite aerogels for multifunctional applications. | Zhao-Hui Zhang Zuan-Yu Chen Yi-Hao Tang Yu-Tong Li Dequan Ma Guo-Dong Zhang Rabah Boukherroub Cheng-Fei Cao Li-Xiu Gong Pingan Song Kun Cao Long-Cheng Tang | 2022 | Journal of Materials Science & Technology2022，，19： | 2 |
| 10 | On-board measurement of emissions from liquefied petroleum gas,gasoline and diesel powered passenger cars in Algeria显示文摘On-board measurements of unit emissions of CO,HC,NOx and CO2 were conducted on 17 private cars powered by different types of fuels including gasoline,dual gasoline–liquefied petroleum gas(LPG),gasoline,and diesel. The tests performed revealed the effect of LPG injection technology on unit emissions and made it possible to compare the measured emissions to the European Artemis emission model. A sequential multipoint injection LPG kit with no catalyst installed was found to be the most efficient pollutant reduction device for all of the pollutants,with the exception of the NOx. Specific test results for a sub-group of LPG vehicles revealed that LPG-fueled engines with no catalyst cannot compete with catalyzed gasoline and diesel engines. Vehicle age does not appear to be a determining parameter with regard to vehicle pollutant emissions. A fuel switch to LPG offers many advantages as far as pollutant emissions are concerned,due to LPG's intrinsic characteristics.However,these advantages are being rapidly offset by the strong development of both gasoline and diesel engine technologies and catalyst converters. The LPG's performance on a chassis dynamometer under real driving conditions was better than expected. The enforcement of pollutant emission standards in developing countries is an important step towards introducing clean technology and reducing vehicle emissions. | Saadane Chikhi Ménouèr Boughedaoui Rabah Kerbachi Robert Joumard | 2014 | Journal of Environmental Sciences2014，26，8： | 2 |
