| 1 | Progress in carbon dioxide separation and capture: A review显示文摘这篇文章考察在 CO2 分离和俘获研究和工程取得的进步。各种各样的技术例如吸收,吸附,和膜分离,彻底地被讨论。象化学循环的燃烧和基于水合物的分离那样的新概念也简短被介绍。未来方向被建议。隐遁方法海洋授精和矿物质碳酸饱和技术例如造林,也被盖住。地下的注射和直接海洋垃圾场没被盖住。 | Hongqun Yang Zhenghe Xu Maohong Fan Rajender Gupta Rachid B Slimane Alan E Bland Ian Wright | 2008 | Journal of Environmental Sciences2008,20,1: | 89 |
| 2 | 中国表土花粉与建群植物地理分布的气候指示性对比显示文摘利用中国建群植物数字化的地理分布数据与1860个中国表土样品花粉数据和气候插值定量分析了中国主要花粉含量与植物种类的地理分布和气候指示性.研究结果显示,绝大多数表土花粉含量的气候指示性与建群植物地理分布的气候区间是吻合的,表土花粉与建群植物的气候阈值的重合取决于花粉与气候的正态分布关系.此外,部分花粉种类指示的气候相对于植物存在一定的偏移,如杜鹃花科、菊科、禾本科和藜科等,这与花粉的分类鉴定水平较低和自然植被的人为干扰有关.本研究在较大空间尺度范围内将表土花粉与建群植物的气候指示性进行对比,为全球生态学、第四纪环境和古气候学研究提供了重要的数据和参照. | 郑卓 黄康有 许清海 吕厚远 Rachid Cheddadi 罗运利 Celia Beaudouin 罗传秀 郑艳伟 李春海 魏金辉 杜春彬 | 2008 | 中国科学(D辑)2008,38,6: | 32 |
| 3 | Inflammatory status in chronic renal failure: The role of homocysteinemia and pro-inflammatory cytokines显示文摘AIM: To evaluate determinants of inflammatory markers in chronic renal failure patients according to the level of glomerular filtration rate. METHODS: One hundred fifty four patients(Age; 44 ± 06 years, male/female; 66/88) with chronic renal failure(CRF) were divided into 6 groups according to the National Kidney Foundation(NKF) classification. They included 28 primary stage renal failure patients(CRF 1), 28 moderate stage renal failure patients(CRF 2),28 severe stage renal failure patients(CRF 3), 18 endstage renal failure patients(CRF 4), 40 hemodialysis(HD) patients, and 12 peritoneal dialysis(PD) patients. Tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), interleukin-6(IL-6) and C-reactive protein(CRP) were analyzed by immunosorbent assay kit(ELISA)(Cayman Chemical's ACETM EIA kit). Immunoassay methods were used for total homocysteine(tH cy)(fluorescence polarization immunoanalysis HPLC, Perkin Emer 200 series), transferrin(MININEPHTM human transferin kit: ZK070.R), ferritin(ADVIA Centaur) and fibrinogen analysis(ACL 200). Differences between groups were performed using SPSS 20.0 and data are expressed as the mean ± SD.RESULTS: Results showed that in comparison with CRF 1 group and other groups, TNF-α and IL-6 levels were respectively more elevated in HD(16.38 ± 5.52 pg/mL vs 0.39 ± 0.03 pg/mL, 11.05 ± 3.59 pg/mL vs 8.20 ± 0.22 pg/mL, P < 0.001) and PD(14.04 ± 3.40 pg/m L vs 0.39 ± 0.03 pg/m L, 10.15 ± 1.66 pg/m L vs 8.20 ± 0.22 pg/m L, P < 0.001). IL-1β levels were increased in HD(9.63 ± 3.50 pg/m L vs 3.24 ± 0.10 pg/mL, P < 0.001) and CRF 4(7.76 ± 0.66 pg/mL vs 3.24 ± 0.10 pg/m L, P < 0.001) patients than in CRF 1 and in the other groups. Plasma t Hcy levels were higher in HD(32.27 ± 12.08 μmol/L) and PD(28.37 ± 4.98 μmol/L) patients compared to the other groups of CRF(P < 0.001). The serum CRP level was significantly increased in HD(18.17 ± 6.38 mg/L) and PD(17.97 ± 4.85 mg/L) patients compared to the other groups of CRF patients(P < 0.001). The plasma fibrinogen level was more elevated in HD(6.86 ± 1.06 g/L) and CRF 4(6.05 ± 0.57 g/L) than in the other groups(P < 0.001). Furthermore; the ferritin level was higher in HD(169.90 ± 62.16 ng/m L) and PD(90.08 ± 22.09 ng/m L) patients compared to the other groups of CRF(P < 0.001). The serum transferrin value was significantly decreased especially in PD(1.78 ± 0.21 g/L) compared to the other groups(P < 0.001). We found a negative correlationbetween glomerular filtration rate(GFR), TNF-α levels(r =-0.75, P < 0.001), and t Hcy levels(r =-0.68, P < 0.001). We observed a positive correlation between GFR and transferrin levels(r = 0.60, P < 0.001). CONCLUSION: CRF was associated with elevated inflammatory markers. The inflammation was observed at the severe stage of CRF and increases with progression of renal failure. | Hadja Fatima Tbahriti Djamel Meknassi Rachid Moussaoui Amar Messaoudi Lakhdar Zemour Abbou Kaddous Malika Bouchenak Khedidja Mekki | 2013 | World Journal of Nephrology2013,2,2: | 32 |
| 4 | Comparison of climatic threshold of geographical distribution between dominant plants and surface pollen in China显示文摘The geographical distribution of dominant plant species in China was georeferenced and climatic variables were interpolated into all grids.Accordingly,the percentage distributions of principal pollen taxa based on 1860 surface pollen sites in China were selected and the related climate values were interpolated with the same method. The geographical and climatic comparison between the two data-sets indicated that the climate threshold of most pollen taxa from surface pollen is coherent with plant distributions. The climatic envelopes of dominant plant are mostly accordant with those of pollen taxa at certain levels. However, some distinct offsets of the climate ranges exist between the two datasets for most pollen taxa identified at family level, such as Ericaceae,Asteraceae, Poaceae and Chenopodiaceae. The present study provides for the first time rich information on temperature and precipitation in relation to pollen and plant distribution based on the datasets on a continental scale useful for global ecological modeling and Quaternary palaeoclimate reconstruction. | CHEDDADI Rachid BEAUDOUIN Celia | 2008 | Science China Earth Sciences2008,51,8: | 26 |
| 5 | 神农架大九湖四万年以来的植被与气候变化显示文摘通过对大九湖6m长连续沉积岩芯剖面(DJH-1孔)7个样品的AMS14C年龄测定和151块孢粉样品的鉴定分析,揭示了神农架区域4万以年来植被和气候演变。末次冰期阶段大九湖附近发育森林草地或草地—草甸植被。MIS3晚期,~42-39calkaBP之间,气候相对干冷,发育森林草地;~39-31calkaBP之间,气候较为湿润,草甸扩张并伴随低海拔阔叶树种的发育。MIS2阶段,草甸组分中蒿属显著增加,高海拔可能分布有荒漠草地,气候极端干冷;该时期植被带垂直下降达到1000余m,按垂直温度递减率推算,冰盛期阶段该区域温度下降约7℃左右。从冰消期开始,森林植被开始扩张,北温带、暖温带和亚热带乔木组分依次增加。约在9.4-4calkaBP之间,演变为亚热带常绿阔叶落叶林,属全新世适宜期;从约4calkaBP以来,北温带阔叶和针叶树开始增加,气候趋于凉干。通过对比区域高分辨率的洞穴石笋及高纬冰芯氧同位素记录,表明神农架区域植被环境变化对气候变化敏感,并记录了H1,YD气候突变事件;进一步体现出该区域气候环境演变主要与北半球太阳辐射控制的东亚夏季风强度变化有关,且与北半球高纬气候变化一致。 | 李杰 郑卓 Rachid Cheddadi 杨士雄 黄康有 | 2013 | 地理学报2013,68,1: | 19 |
| 6 | Prevalence of type 2 diabetes in Algerian patients with hepatitis C virus infection显示文摘AIM:To investigate the prevalence of,and risk factors for,diabetes mellitus(DM) in Algerian patients with chronic hepatitis C virus(HCV) infection and in a control group.METHODS:A cross-sectional study was undertaken.A total of 416 consecutive patients with viral chronic hepatitis attending the Internal Medicine Department of the University Hospital Center Touhami Benflis in Batna [290 HCV-infected and 126 hepatitis B virus(HBV)-infected patients] were prospectively recruited.RESULTS:The prevalence of DM was higher in HCV-infected patients in comparison with HBV-infected patients(39.1% vs 5%,P < 0.0001).Among patients without cirrhosis,diabetes was more prevalent in HCV-infected patients than in HBV-infected patients(33.5% vs 4.3%,P < 0.0001).Among patients with cirrhosis,diabetes was more prevalent in HCV-infected patients,but the difference was not significant(67.4% vs 20%,P = 0.058).The logistic regression analysis showed that HCV infection [odds ratio(OR) 4.73,95% CI:1.7-13.2],metabolic syndrome(OR 12.35,95% CI:6.18-24.67),family history of diabetes(OR 3.2,95% CI:1.67-6.13) and increased hepatic enzymes(OR 2.22,95% CI:1.1-4.5) were independently related to DM in these patients.CONCLUSION:The high prevalence of diabetes in HCV-infected patients,and its occurrence at early stages of hepatic disease,suggest that screening for glucose abnormalities should be indicated in these patients. | Samir Rouabhia Rachid Malek Hocine Bounecer Aoulia Dekaken Fouzia Bendali Amor Mourad Sadelaoud Abderrahmene Benouar | 2010 | World Journal of Gastroenterology2010,16,27: | 15 |

| 8 | Heat transfer of copper/water nanofluid flow through converging-diverging channel显示文摘The main objective of this work is to investigate analytically the steady nanofluid flow and heat transfer characteristics between nonparallel plane walls. Using appropriate transformations for the velocity and temperature, the basic nonlinear partial differential equations are reduced to the ordinary differential equations. Then, these equations have been solved analytically and numerically for some values of the governing parameters, Reynolds number, Re, channel half angle, α, Prandtl number, Pr, and Eckert number, Ec, using Adomian decomposition method and the Runge-Kutta method with mathematic package. Analytical and numerical results are searched for the skin friction coefficient, Nusselt number and the velocity and temperature profiles. It is found on one hand that the Nusselt number increases as Eckert number or channel half-angle increases, but it decreases as Reynolds number increases. On the other hand, it is also found that the presence of Cu nanoparticles in a water base fluid enhances heat transfer between nonparallel plane walls and in consequence the Nusselt number increases with the increase of nanoparticles volume fraction. Finally, an excellent agreement between analytical results and those obtained by numerical Runge-Kutta method is highly noticed. | Mohamed Rafik SARI Mohamed KEZZAR Rachid ADJABI | 2016 | Journal of Central South University2016,23,2: | 11 |
| 9 | Gallstone-related complications after Roux-en-Y gastric bypass:a prospective study显示文摘BACKGROUND: Gastric bypass is a widespread bariatric procedure that carries a high incidence of gallstone formation postoperatively. Controversy exists regarding the importance and consequences of gallstones in these patients. There are surgeons who consider gallstone-related complications after gastric bypass important enough to require routine removal of the gallbladder during gastric bypass (prophylactic cholecystectomy). However, this can lead to increased costs and risks. This study aimed to identify complications related to cholelithiasis after Roux-en-Y gastric bypass (RYGBP). METHODS: This is a prospective observational study of 40 morbidly obese patients free of gallbladder disease. The patients underwent open RYGBP at a public hospital in Brazil from February to October 2007. They were followed up clinically and ultrasonographically at 6 months and 1, 2, and 3 years after surgery. Of the patients, 38 patients were followed up for 3 years. RESULTS: Eleven patients (28.9%) developed cholelithiasis, four (10.5%) experienced biliary pain, and 2 suffered from acute biliary pancreatitis (5.3%). These patients had their gallbladders removed laparoscopically. No patient presented with acute cholecystitis, choledocholithiasis, or bile duct dilation during the follow-up period. There were no deaths. CONCLUSIONS: Gallstone-related complications after RYGBP were relatively common. Some of these complications, like acute pancreatitis, are known to have potentially severe outcomes. It seems reasonable to perform cholecystectomy during gastric bypass in the presence of cholelithiasis or after this procedure if gallstones develop. | Rachid G Nagem Alcino Lázaro-da-Silva Rafael Morroni de Oliveira Valter Garcia Morato | 2012 | Hepatobiliary & Pancreatic Diseases International2012,11,6: | 10 |

| 14 | Mitochondrial dysfunction,oxidative stress and apoptotic induction in microglial BV-2 cells treated with sodium arsenate显示文摘The treatment of microglial BV-2 cells with sodium arsenate(As(V):0.1-400 μmol/L — 48 hr)induces a dose-dependent response.The neurotoxic effects of high concentrations of As(V)(100,200 and 400 μmol/L) are characterized by increased levels of mitochondrial complexesⅠ,Ⅱ,and Ⅳ followed by increased superoxide anion generation.Moreover,As(V) triggers an apoptotic mode of cell death,demonstrated by an apoptotic SubG1 peak,associated with an alteration of plasma membrane integrity.There is also a decrease in transmembrane mitochondrial potential and mitochondrial adenosine triphosphate ATP.It is therefore tempting to speculate that As(V) triggers mitochondrial dysfunction,which may lead to defective oxidative phosphorylation subsequently causing mitochondrial oxidative damage,which in turn induces an apoptotic mode of cell death. | Wafa Kharroubi Samia Hai Ahmed Thomas Nury Pierre Andreoletti Rachid Sakly Mohamed Hammami Gerard Lizard | 2017 | Journal of Environmental Sciences2017,29,1: | 5 |

| 18 | 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 |
| 19 | Hepatic encephalopathy:Lessons from preclinical studies显示文摘Hepatic encephalopathy(HE) is a major complication that is closely related to the progression of end-stage liver disease.Metabolic changes in advanced liver failure can promote cognition impairment,attention deficits and motor dysfunction that may result in coma and death.HE can be subdivided according to the type of hepatic injury,namely,type A,which results from acute liver failure,type B,which is associated with a portosystemic shunting without intrinsic liver disease,and type C,which is due to chronic liver disease.Several studies have investigated the pathogenesis of the disease,and most of the mechanisms have been explored using animal models.This article aimed to review the use of preclinical models to investigate HE.The most used animal species are rats and mice.Experimental models of type A HE include surgical procedures and the administration of hepatotoxic medications,whereas models of types B and C HE are generally surgically induced lesions in liver tissue,which evolve to hepatic cirrhosis.Preclinical models have allowed the comprehension of the pathways related to HE. | Luiza Cioglia Dias Lima Aline Silva Miranda Rodrigo Novaes Ferreira Milene Alvarenga Rachid Ana Cristina Sim?es e Silva | 2019 | World Journal of Hepatology2019,11,2: | 4 |
| 20 | Improved Non-Covalent Biofunctionalization of Multi-Walled Carbon Nanotubes Using Carbohydrate Amphiphiles with a Butterfly-Like Polyaromatic Tail显示文摘We have developed an efficient strategy for the non-covalent functionalization of multi-walled carbon nanotubes(MWCNTs)which allows a biomimetic presentation of carbohydrates on their surface byπ-πstacking interactions.The strategy is based on the use of sugar-based amphiphiles functionalized with tetrabenzo[a,c,g,i]fluorene(Tbf),a polyaromatic compound with a topology that resembles a butterfly with open wings.The new carbohydrate-tethered Tbf amphiphiles have been synthesized in a straightforward manner using click chemistry.The reported method has been developed in order to improve the rather low ability of pyrene-based systems to exfoliate MWCNTs in water.By means of thermogravimetric analysis(TGA),ultraviolet(UV),infrared(IR),and fluorescence spectroscopies the interaction between MWCNTs and the Tbf group has been found to be stronger than those involving pyrene-based amphiphilic carbohydrates.The resulting aggregates with a multivalent sugar exposition on their surface are able to engage in specific ligand-lectin interactions similar to glycoconjugates on a cell membrane. | Mohyeddin Assali Manuel Pernía Leal Inmaculada Fernández Pablo Romero-Gomez Rachid Baati Noureddine Khiar | 2010 | Nano Research2010,3,11: | 3 |
