| 1 | Mg(OH)_2 Nanorods Synthesized by A Facile Hydrothermal Method in the Presence of CTAB显示文摘Magnesium hydroxide(Mg(OH)_2) nanorods were synthesized by a simple and facile hydrothermal method in the presence of cetyltetramethylammonium bromide(CTAB) as a surfactant. Nanorods of magnesium oxide Mg O were also induced by thermal decomposition of Mg(OH)_2 nanorods at 700. By using disk diffusion technique, the Mg(OH)_2 nanorods were found to exhibit higher antibacterial efficiency against several tested bacterial strains. | Hassouna Dhaouadi Hedia Chaabane Fathi Touati | 2011 | Nano-Micro Letters2011，3，3： | 9 |
| 2 | UV/Vis Characterization and Fate of Organic Amendment Fractions in a Dune Soil in Dakar, Senegal显示文摘The application of organic amendments on soils poor in organic matter(OM) can improve long-term soil fertility, but may also enhance the mineralization of native soil organic matter. Three organic amendments, compost, sewage sludge and horse manure, used by urban market gardeners in Dakar, Senegal were analyzed for their OM maturity. Their fate was evaluated in a 45-d agronomic trial in a sandy Arenosol with lettuce. In each case, water-extractable organic matter(WEOM) and humic-like substances(HLS)were isolated from raw amendments and amended soils, and characterized using ultraviolet-visible(UV/Vis) spectroscopy. Results highlighted the general more aromatic character of HLS and WEOM fractions extracted from compost compared to the other two amendments. When applied to soils, however, these differences were not clearly observed. The aromaticity and humification degree of the labile fraction(WEOM) increased with depth in the first 30 cm for all amendments. This indicated the high lixiviation rates that fresh OM underwent in the studied sandy soil. Finally, a statistical analysis of the results was able to discriminate between surface and deeper horizons and between amended- and non-amended soil samples. Spectroscopic indices showed indeed strong increase/decrease with depth linked with the mineralization/humification processes that the fresh OM from amendments underwent during the 45 d of the agronomic trial. This study highlights the potential of spectroscopic techniques to study agricultural amendment organic matter fractions and their fate in soils. | Silwan DAOUK Mohammad HASSOUNA Anne GUEYE-GIRARDET Seydou NIANG Hans-Rudolf PFEIFER | 2015 | Pedosphere2015，25，3： | 6 |
| 3 | Novel non-invasive biological predictive index for liver fibrosis in hepatitis C virus genotype 4 patients显示文摘AIM To investigate the diagnostic ability of a non-invasive biological marker to predict liver fibrosis in hepatitis C genotype 4 patients with high accuracy.METHODS A cohort of 332 patients infected with hepatitis C genotype 4 was included in this cross-sectional study. Fasting plasma glucose, insulin, C-peptide, and angiotensinconverting enzyme serum levels were measured. Insulin resistance was mathematically calculated using the homeostasis model of insulin resistance(HOMA-IR).RESULTS Fibrosis stages were distributed based on Metavir score as follows: F0 = 43, F1 = 136, F2 = 64, F3 = 45 and F4 = 44. Statistical analysis relied upon reclassification of fibrosis stages into mild fibrosis(F0-F) = 179, moderate fibrosis(F2) = 64, and advanced fibrosis(F3-F4) = 89. Univariate analysis indicated that age, log aspartate amino transaminase, log HOMA-IR and log platelet count were independent predictors of liver fibrosis stage(P < 0.0001). A stepwise multivariate discriminant functional analysis was used to drive a discriminative model for liver fibrosis. Our index used cut-off values of ≥ 0.86 and ≤-0.31 to diagnose advanced and mild fibrosis, respectively, with receiving operating characteristics of 0.91 and 0.88, respectively. The sensitivity, specificity, positive predictive value, negative predictive value and positive likelihood ratio were: 73%, 91%, 75%, 90% and 8.0 respectively for advanced fibrosis, and 67%, 88%, 84%, 70% and 4.9, respectively, for mild fibrosis.CONCLUSION Our predictive model is easily available and reproducible, and predicted liver fibrosis with acceptable accuracy. | Mahmoud Khattab Mohamed Amin Sakr Mohamed Abdel Fattah Youssef Mousa Elwy Soliman Ashraf Breedy Mona Fathi Salwa Gaber Ahmed Altaweil Ashraf Osman Ahmed Hassouna Ibrahim Motawea | 2016 | World Journal of Hepatology2016，8，32： | 2 |
