AIM:To investigate the expression of chondroitin sulphate proteoglycans(CSPGs)in rat liver tissues of hepatocellular carcinoma(HCC).METHOdS:Thirty male Sprague dawley rats were randomly divided into two groups:control group(n=10) and HCC model group(n=20).Rats in the HCC model groups were intragastrically administrated with 0.2%(w/v)N-diethylnitrosamine(dEN)every 5 d for 16 wk,whereas 0.9%(w/v)normal saline was administered to rats in the control *** 16 wk from the initiation of experiment,all rats were killed and livers were collected and fixed in 4%(w/v)*** tissues were embedded in paraffin and *** staining(hematoxylin and eosin and Toluidine blue)was performed to demonstrate the onset of HCC and the content of sulphated glycosaminoglycan(sGAG).Immunohistochemical staining was performed to investigate the expression of chondroitin sulphate(CS)/dermatan sulphate(dS)-GAG,heparan sulphate(HS)-GAG,keratan sulphate(KS)-GAG in liver ***,expression and distribution of CSPG family members,including aggrecan,versican,biglycan and decorin in liver tissues,were also immunohistochemically ***:After 16 wk administration of dEN,malignant nodules were observed on the surface of livers from the HCC model group,and their hepatic lobule structures appeared largely disrupted under *** blue staining demonstrated that there was an significant increase in sGAG content in HCC tissues when compared with that in the normal liver tissues from the control group[0.37±0.05 integrated optical density per stained area(IOd/area)and 0.21± 0.01 IOd/area,Pdies demonstrated that this increased sGAG in HCC tissues was induced by an elevated expression of CS/dS(0.28±0.02 IOd/area and 0.18±0.02 IOd/area,Pd HS(0.30±0.03 IOd/area and 0.17±0.02 IOd/area,Pdies thereby were performed to investigate the expression and distribution o

Eugene岛 330区块油田的GA层段属晚更新世(距今约 0.8Ma)陆架边缘低水位三角洲复合体沉积。本文综合三维(3-d)地震、电缆测井、岩心和岩屑资料研究该三角洲的内部结构并重建其沉积史。该层段表现为在短距离(几千米)内河道、斜坡地形和坡脚滑塌沉积物呈复杂的垂向和侧向指状交叉,是由同沉积构造演化(生长断层、滚动背斜)和相对海平面变化伴随的三角洲舌体前积及转换作用的产物。然后,我们将层序地层解释与生产数据结合起来。该层段中的油气聚集主要与其顶部海泛面之下的上倾岩相(三角洲河口坝、三角洲前缘)有关,而不是与层段底部的层序边界有关。与 GA层段顶部有关的地震振幅图显示为斑块状(河口坝沉积)和曲线状(分流间三角洲前缘)趋势,表明了与沉积特征有关的储层非均质特性。地震振幅与生产特性间有良好的定性关系,位于构造高点的高振幅区产量最高。

最近十年3d电影再度成为一个备受瞩目的话题。关于3d电影的学术研究常常集中在技术革新,却忽略了电影形式与内容的关系。3d电影的美学和叙事范式中最值得注意的问题之一是立体的电影凝视,从原初的眼球刺激到种族凝视与叙事空间的探索,我们可以沿着这些脉络去发现立体凝视如何建构一个个世界,而这些世界也为这种凝视而存在。
