2改进的石墨烯基材料用作菜籽油转酯化反应制生物柴油的有效催化剂(英文)显示文摘本文研究了不同石墨烯基材料用作转酯化反应制备生物柴油催化剂的性能.将磺酸基或磷酸盐基嫁接到热还原的氧化石墨烯表面,制备了固体酸石墨烯基样品.并采用扫描电镜、X射线衍射、热重分析、X射线光电子能谱、N2吸附-脱附法、电位滴定法、元素分析以及红外光谱法对所制样品进行了全面表征.将所制样品用于130 oC带压力的条件下菜籽油与甲醇转酯化反应中,并将其催化活性与商用的多相酸催化剂Amberlyst-15的进行了比较.结果表明,所有改进的样品在转酯化反应中均表现出催化活性,但各样品上生物柴油产率差别较大.其中以苯二氮磺酸基功能化的热还原氧化石墨烯样品上脂肪酸甲酯产率最高,反应6 h后达70%,也明显高于商用催化剂Amberlyst-15.该样品也表现出良好的重复使用性能.Justina Gaidukevic Jurgis Barkauskas Anna Malaika Paulina Rechnia-Goracy Aleksandra Mozdzynska Vitalija Jasulaitiene Mieczyslaw Kozlowski 2018Chinese Journal of Catalysis2018,39,10:6

5Delonix regia and Casuarina equisetifolia as passive biomonitors and as bioaccumulators of atmospheric trace metals显示文摘The suitability of two common and ubiquitously distributed and exotic ornamental plant species in Nigeria-Delonix regia and Casuarina equisetifolia as biomonitors and as effective bioaccumulators of atmospheric trace metals(Cd,Pb,Zn and Cu) has been evaluated.Bark and leaf samples from these plant species were collected in June and July 2006 at five locations in Benin City.Four of the sampling sites were in areas of high traffic density and commercial activities,the fifth site is a remote site,selected to act as a control and also to provide background information for the metals.The plant samples were collected and processed using standard procedures and trace metals were determined using atomic absorption spectrometer.The bark of the plants was able to bioaccumulate the trace metals,especially Pb which originates from anthropogenic contributions in the city.The Pb range of 20.00-70.00 μg/g measured for the bark samples of D.regia,exceeded the normal plant Pb concentration of 0.2-20.0 μg/g and most Pb data available in literature.The bark of the plants was observed to accumulate more metals compared to the leave,while D.regia was found to be slightly better than C.equisetifolia in trace metal uptake efficiency.Spatial variations in the distributions of Pb and Zn were significant(p < 0.05),and the continuous use of leaded fuel in Nigeria was identified as the predominant source of Pb in the atmosphere.Emmanuel Ehiabhi Ukpebor Justina Ebehirieme Ukpebor Emmanuel Aigbokhan Idris Goji Alex Okiemute Onojeghuo Anthony Chinedum Okonkwo 2010Journal of Environmental Sciences2010,22,7:2
6Evaluation of biodegradable electric conductive tube-guides and mesenchymal stem cells显示文摘AIM: To study the therapeutic effect of three tubeguides with electrical conductivity associated to mesenchymal stem cells(MSCs) on neuro-muscular regeneration after neurotmesis.METHODS: Rats with 10-mm gap nerve injury were tested using polyvinyl alcohol(PVA), PVA-carbon nanotubes(CNTs) and MSCs, and PVA-polypyrrole(PPy). The regenerated nerves and tibialis anterior muscles were processed for stereological studies after 20 wk. The functional recovery was assessed serially for gait biomechanical analysis, by extensor postural thrust, sciatic functional index and static sciatic functionalindex(SSI), and by withdrawal reflex latency(WRL). In vitro studies included cytocompatibility, flow cytometry, reverse transcriptase polymerase chain reaction and karyotype analysis of the MSCs. Histopathology of lung, liver, kidneys, and regional lymph nodes ensured the biomaterials biocompatibility. RESULTS: SSI remained negative throughout and independently from treatment. Differences between treted groups in the severity of changes in WRL existed, showing a faster regeneration for PVA-CNTs-MSCs(P < 0.05). At toe-off, less acute ankle joint angles were seen for PVA-CNTs-MSCs group(P = 0.051) suggesting improved ankle muscles function during the push off phase of the gait cycle. In PVA-PPy and PVA-CNTs groups, there was a 25% and 42% increase of average fiber area and a 13% and 21% increase of the 'minimal Feret's diameter' respectively. Stereological analysis disclosed a significantly(P < 0.05) increased myelin thickness(M), ratio myelin thickness/axon diameter(M/d) and ratio axon diameter/fiber diameter(d/D; g-ratio) in PVA-CNT-MSCs group(P < 0.05). CONCLUSION: Results revealed that treatment with MSCs and PVA-CNTs tube-guides induced better nerve fiber regeneration. Functional and kinematics analysis revealed positive synergistic effects brought by MSCs and PVA-CNTs. The PVA-CNTs and PVA-PPy are promising scaffolds with electric conductive properties, bio- and cytocompatible that might prevent the secondary neurogenic muscular atrophy by improving the reestablishment of the neuro-muscular junction.Jorge Ribeiro Tiago Pereira Ana Rita Caseiro Paulo Armada-da-Silva Isabel Pires Justina Prada Irina Amorim Sandra Amado Miguel Franca Carolina Goncalves Maria Ascensao Lopes Jose Domingos Santos Dina Morais Silva Stefano Geuna Ana Lúcia Luís Ana Colette Maurício 2015World Journal of Stem Cells2015,7,6:2
7Endothelial parameters in central and peripheral cornea in patients wearing contact lenses显示文摘AIM: To measure the parameters of endothelium in the central and peripheral parts of the cornea and evaluate the influence of wearing the hard and soft contact lenses on the mentioned parameters.METHODS: A specular microscope was used to measure the corneal endothelium parameters in both eyes of 139 Caucasians(a total of 278). All participants were divided into three groups: soft lens wearers, hard lens wearers and a control group. Factors, such as age, smoking, types of lens material, duration of lens wear and lens air permeability were assessed to determine their impact on the morphometric parameters of the endothelium.RESULTS: A lower percentage of hexagon-like cells and higher cell variation than in other groups were determined in hard contact lens wearers. The difference in density of endotheliocytes between the groups was not observed. The measurements of the morphometric parameters in soft contact lens wearers did not depend neither on the duration of lens wear, nor on air permeability. The relation between the patients' age and the variation of endothelium parameters was determined in the group of hard contact lens wearers.CONCLUSION: Wearing hard contact lenses provokes pleomorphism and polymegethism of the corneal endothelium, while soft contact lenses do not impact any parameters of the endothelium, most likely due to higher air permeability.Saulius Galgauskas Justina Ignataviciute Zivile Vieversyte Rimvydas Asoklis 2018International Journal of Ophthalmology(English edition)2018,11,11:2

20Epidemiological trends and geographic variation in hospital admissions for diverticulitis in the United States显示文摘AIM:To characterize the increasing incidence and geographic variation of acute diverticulitis.METHODS:Using the nationwide inpatient sample (NIS) we identified a cohort who had been admitted with diverticulitis between 1998 and 2005.We calculated age-,sex-,and region-specific rates of hospitalizations for diverticulitis over time.RESULTS:The age-adjusted hospitalization rate for diverticulitis increased from 61.8 per 100000 to 75.5 per 100 000 between 1998 and 2005,and increased similarly in both sexes.Diverticulitis-associated admissions were male-predominant in those younger than age 45 years but were female-predominant thereafter.Admission rates increased the most among those<45 years,while remaining unchanged for those≥65 years.By 2005,the majority of hospitalized patients were<65 years.Age-adjusted rates of diverticulitis-associated hospitalizations were lower in the West(50.4/100000) compared to the Northeast(77.7/100000),South (73.9/100000),and Midwest(71.0/100000).CONCLUSION:Diverticulitis-associated hospitalizations have steeply risen,especially in young adults.These epidemiological trends vary by geographic region and warrant further investigation into potential dietary and environmental etiologies.Geoffrey C Nguyen Justina Sam Nitasha Anand 2011World Journal of Gastroenterology2011,17,12:1
