4不同端基聚氨酯-丙烯酸酯复合细乳液的表征显示文摘采用异佛尔酮二异氰酸酯、聚丙二醇经1,4-丁二醇扩链的聚氨酯(PU),再经过甲醇或甲基丙烯酸羟乙酯封端后溶解在丙烯酸酯单体中,超声乳化后进行自由基细乳液聚合。NCO和OCH3为端基的PU构成的复合乳液GPC谱图都呈现两个峰,DSC和FT-IR分析发现,复合后增加了PU软段和硬段相分离的程度。甲基丙烯酸封端的复合乳液生成交联型聚合物,PU的硬段和硬段间的氢键也受到破坏。复合聚合物膜表面元素含量和本体接近,表明复合细乳液粒子未形成核-壳型结构。王春鹏 储富祥 金立维 林明涛 GUYOT Alain 2006高分子材料科学与工程2006,22,5:4

6Smoothelin,a new marker to determine the origin of liver fibrogenic cells显示文摘AIM:To explore this hypothesis that smooth muscle cells may be capable of acquiring a myofibroblastic phenotype,we have studied the expression of smoothelin in fibrotic conditions.METHODS:Normal liver tissue(n=3)was obtained from macroscopically normal parts of hepatectomy,taken at a distance from hemangiomas.Pathological specimens included post-burn cutaneous hypertrophic scars(n=3),fibrotic liver tissue(n=5),cirrhotic tissue(viral and alcoholic hepatitis)(n=5),and hepatocellular carcinomas(n=5).Tissue samples were fixed in 10%formalin and embedded in paraffin for immunohistochemistry or were immediately frozen in liquid nitrogen-cooled isopentane for confocal microscopy analysis.Sections were stained with antibodies against smoothelin,which is expressed exclusively by smooth muscle cells,andα-smooth muscle actin,which is expressed by both smooth muscle cells and myofibroblasts.RESULTS:In hypertrophic scars,α-smooth muscle actin was detected in vascular smooth muscle cells and in numerous myofibroblasts present in and around nodules,whereas smoothelin was exclusively expressed in vascular smooth muscle cells.In the normal liver,vascular smooth muscle cells were the only cells that expressα-smooth muscle actin and smoothelin.In fibrotic areas of the liver,myofibroblasts expressingα-smooth muscle actin were detected.Myofibroblasts co-expressingα-smooth muscle actin and smoothelin were observed,and their number was slightly increased in parallel with the degree of fibrosis(absent in liver with mild or moderate fibrosis;5%to 10%positive in liver showing severe fibrosis).In cirrhotic septa,numerous myofibroblasts co-expressedα-smooth muscle actin and smoothelin(more than 50%).In hepatocellular carcinomas,the same pattern of expression forα-smooth muscle actin and smoothelin was observed in the stroma reaction surrounding the tumor and around tumoral cell plates.In all pathological liver samples,α-smooth muscle actin and smoothelin were co-expressed in vascular smooth muscle cells.CONCLUSION:During development of advanced liver fibrosis,a subpopulation of myofibroblasts expressing smoothelin may be derived from vascular smooth muscle cells,illustrating the different cellular origins of myofibroblasts.Sébastien Lepreux Christelle Guyot Fabrice Billet Chantal Combe Charles Balabaud Paulette Bioulac-Sage Alexis Desmoulière 2013World Journal of Gastroenterology2013,19,48:2

11CO2-induced destabilization of pyrite-structured FeO2Hx in the lower mantle显示文摘Volatiles, such as carbon and water, modulate the Earth's mantle rheology, partial melting and redox state,thereby playing a crucial role in the Earth's internal dynamics. We experimentally show the transformation of goethite FeOOH in the presence of CO_2 into a tetrahedral carbonate phase, Fe_4C_3O_(12), at conditions above 107 GPa—2300 K. At temperatures below 2300 K, no interactions are evidenced between goethite and CO_2, and instead a pyrite-structured FeO_2 Hx is formed as recently reported by Hu et al.(2016; 2017)and Nishi et al.(2017). The interpretation is that, above a critical temperature, FeO_2 Hx reacts with CO_2 and H_2, yielding Fe_4C_3O_(12) and H_2 O. Our findings provide strong support for the stability of carbon-oxygen-bearing phases at lower-mantle conditions. In both subducting slabs and lower-mantle lithologies, the tetrahedral carbonate Fe_4C_3O_(12) would replace the pyrite-structured FeO_2 Hx through carbonation of these phases. This reaction provides a new mechanism for hydrogen release as H2 O within the deep lower mantle. Our study shows that the deep carbon and hydrogen cycles may be more complex than previously thought, as they strongly depend on the control exerted by local mineralogical and chemical environments on the CO_2 and H_2 thermodynamic activities.Eglantine Boulard Francois Guyot Nicolas Menguy Alexandre Corgne Anne-Line Auzende Jean-Philippe Perrillat Guillaume Fiquet 2018National Science Review2018,5,6:2
