1A Review of the Tetrapod Track Record in China,with Special Reference to Type Ichnospecies:Implications for Ichnotaxonomy and Paleobiology显示文摘切开并且 lumping 是在脊椎动物的永久问题,特别恐龙, ichnotaxonomy。中国恐龙 ichnotaxonomy,在 1940 开始了,提供一系列有趣的案例研究,加亮历史、可疑的 ichnotaxonomy 的双问题。中国中生代四足动物的轨道类型被放进 63 ichnospecies (一个三叠纪, 28 侏罗记,和 34 白垩纪) ,从中国识别的其它,非类型 ichnospecies 或 ichnotaxa 独占。(83%) 52 这 63 四足动物的 ichnospecies 被放在 monospecific ichnogenera。在 ichnogenus 水平,我们由认出 nomina dubia 或由从 53 恐龙的 ichnogenera (32% 减小) 的表的 synonymy17 的 pruneeither,离开我们认为有效的 36 ichnotaxa。大多数切割影响侏罗记 theropod ichnotaxa,它仅仅从 23 被归结为九因为大多数 ichnogenera 是 Grallator 和 Eubrontes 的主观年轻同义词。更少中国白垩纪 ichnotaxa (仅仅 21 ichnogenera 中的六个) 是明显的 nomina dubia 或主观同义词,建议更大的东方亚洲人 endemism 在期间这次。因为 ichnospecies 差别是微妙的,我们暂时地作为同种的 ichnospecies 的有效未解决的详细比较分析保留 ichnospecies。这合成是长迟到的并且对历史、省的 ichnotaxonomy 的地址问题必要,它严重地在空间和时间妨碍四足动物的 ichnofaunas 的比较。Martin G.LOCKLEY LI Jianjun LI Rihui Masaki MATSUKAWA Jerald D.HARRIS XING Lida 2013Acta Geologica Sinica(English Edition)2013,87,1:19
2记河北赤城上侏罗统-下白垩统土城子组窄足龙-巨齿龙(兽脚类恐龙)足迹组合及其古生态学意义(英文)显示文摘记述了河北省赤城县落凤沟化石点163个窄足龙足迹(Therangospodus isp.)。当该地区洪水泛滥时,同样的造迹者留下了5个游泳迹。一个异常大的足迹和一道疑似尾迹被归入巨齿龙足迹(Megalosauripus isp.)。土城子组7个主要足迹化石点表明,兽脚类的似鹬龙足迹型(Grallator morphotype)占据主导地位,这些足迹型的大小在各个足迹化石点都有着特定的范围。如果这些大小不同的足迹属于同一种造迹者,则暗示着同年龄的成员在特定年龄时会共同栖息在一起,在动物行为学上类似现生的一些蜥蜴和短吻鳄;如果这些足迹由不同的造迹者组成,则暗示着不同大小的种(主要表现在小型动物)可能拥有自己的领地,并特意避免与其他动物(特别是大型动物)相接触,在动物行为学上类似现生的肉食性哺乳动物。邢立达 Jerald D.HARRIS Gerard D.GIERLINSKI 2011古脊椎动物学报2011,49,4:18
3白垩纪四足动物足印的生物地层学、生物年代学与遗迹相显示文摘从全球范围来看,白垩纪四足动物的足印多数是非鸟恐龙与鸟类留下的痕迹;少量足印来自翼龙、鳄鱼、龟、哺乳动物和其他四足动物。白垩纪的足迹化石以东亚(尤其是中国和朝鲜)和北美西部的最为人所知。南美(主要是阿根廷和巴西)也有一定数量广泛分布的足迹化石,欧洲、非洲与澳大利亚的白垩纪足迹组合则鲜为人知。以白垩纪四足动物的足印记录为基础,我们对两个全球足印生物年代重新进行了检查。早白垩世生物年代以蜥脚类与鸟脚类的足迹为特征。晚白垩世生物年代中的蜥脚类足迹较少,但是鸭嘴龙、暴龙和角龙的足迹增多了。另外,白垩纪足印化石的记录中记载了许多重要的生物地层学信息,如北美白垩纪中期蜥脚类恐龙的消失,以及白垩纪末恐龙的绝灭。越来越多来自东亚的白垩纪足印记录使我们对更精细的地方性白垩纪足印生物年代学有了初步印象。因此,以地方性四足恐龙(包括鸟类)遗迹属的地层分布为基础,可以识别出三个或四个足印生物年代。种类丰富并具有地方性特色的东亚的白垩纪鸟类动物的遗迹群,可能指示白垩纪时东亚存在着一个独特而繁盛的鸟类动物群。以足印化石为基础的这一假说有待进一步的验证。Martin G.LOCKLEY Spencer G.

4Genetically modified mouse models for the study of nonalcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD) is associated with obesity,insulin resistance,and type 2 diabetes.NAFLD represents a large spectrum of diseases ranging from(1) fatty liver(hepatic steatosis);(2) steatosis with inflammation and necrosis;to(3) cirrhosis.The animal models to study NAFLD/nonalcoholic steatohepatitis(NASH) are extremely useful,as there are still many events to be elucidated in the pathology of NASH.The study of the established animal models has provided many clues in the pathogenesis of steatosis and steatohepatitis,but these remain incompletely understood.The different mouse models can be classified in two large groups.The first one includes genetically modified(transgenic or knockout) mice that spontaneously develop liver disease,and the second one includes mice that acquire the disease after dietary or pharmacological manipulation.Although the molecular mechanism leading to the development of hepatic steatosis in the pathogenesis of NAFLD is complex,genetically modified animal models may be a key for the treatment of NAFLD.Ideal animal models for NASH should closely resemble the pathological characteristics observed in humans.To date,no single animal model has encompassed the full spectrum of human disease progression,but they can imitate particular characteristics of human disease.Therefore,it is important that the researchers choose the appropriate animal model.This review discusses various genetically modified animal models developed and used in research on NAFLD.Perumal Nagarajan M Jerald Mahesh Kuma Ramasamy Venkatesan Subeer S Majundar Ramesh C Juyal M Jerald Mahesh Kuma 2012World Journal of Gastroenterology2012,18,11:7

15Long-term and non-invasive in vivo tracking of DiD dye-labeled human hepatic progenitors in chronic liver disease models显示文摘BACKGROUND Chronic liver diseases(CLD)are the major public health burden due to the continuous increasing rate of global morbidity and mortality.The inherent limitations of organ transplantation have led to the development of stem cell-based therapy as a supportive and promising therapeutic option.However,identifying the fate of transplanted cells in vivo represents a crucial obstacle.AIM To evaluate the potential applicability of DiD dye as a cell labeling agent for longterm,and non-invasive in vivo tracking of transplanted cells in the liver.METHODS Magnetically sorted,epithelial cell adhesion molecule positive(1×106 cells/mL)fetal hepatic progenitor cells were labeled with DiD dye and transplanted into the livers of CLD-severe combined immunodeficiency(SCID)mice.Near-infrared(NIR)imaging was performed for in vivo tracking of the DiD-labeled transplanted cells along with colocalization of hepatic markers for up to 80 d.The existence of human cells within mouse livers was identified using Alu polymerase chain reaction and sequencing.RESULTS NIR fluorescence imaging of CLD-SCID mice showed a positive fluorescence signal of DiD at days 7,15,30,45,60,and 80 post-transplantation.Furthermore,positive staining of cytokeratin,c-Met,and albumin colocalizing with DiD fluorescence clearly demonstrated that the fluorescent signal of hepatic markers emerged from the DiD-labeled transplanted cells.Recovery of liver function was also observed with serum levels of glutamic-oxaloacetic transaminase,glutamate-pyruvate transaminase,and bilirubin.The detection of human-specific Alu sequence from the transplanted mouse livers provided evidence for the survival of transplanted cells at day 80.CONCLUSION DiD-labeling is promising for long-term and non-invasive in vivo cell tracking,and understanding the regenerative mechanisms incurred by the transplanted cells.Chaturvedula Tripura Srinivas Gunda Sandeep Kumar Vishwakarma Avinash Raj Thatipalli Jedy Jose Mahesh Kumar Jerald Aleem Ahmed Khan Gopal Pande 2022World Journal of Hepatology2022,14,10:1
