1Fischer Plots of Wumishan Cyclothems,Precambrian Records of Third-OrderSea-Level Changes显示文摘The Mesoproterozoic Wumishan Formation ((1310 ± 20 ) Ma - (l 207 ± 10) Ma) in Jixian, Tianjin represents a succession of 3 300 meter thick carbonate strata where are the best developed stromatolite biostromes and thrombolite bioherms. These biostromes and bioherms, together with tidal-flat dolomites and muddy dolostones, form Wumishan cyclothems with approximately symmetrical faciessuccession fabrics, which belong to carbonate meter-scale cyclic sequences of peritidal type. These cyclothems are overlain by lagoon dolomitic mudstones and shales and by frequently developed paleosol layers, indicating that the boundary of Wumishan cyclothems is marked by an instantaneously-exposed punctuated surface. Viewed form the regularly vertical stacking patterns of Wumishan cyclothems in long-term sequences, 26 third-order sequences may be discerned in Wumishan Formation. These thirdorder sequences may also be incorporated into six second-order sequences. In order to study the variation range of third-order sea-level changes and the formation period of third-order sequence, 626 cyclothems are discerned in the middle and upper parts of Wumishan Formation where the outcrops are well developed. In terms of the total thickness and the formation period of Mesoproterozoic Wumishan Formation, the crust subsidence rate in the sedimentary period of Wumishan Formation is supposed to be 3 meters at each interval of 100 thousands years. Based on this assumption, Fischer plot might be designed to simulate the third-order sea-level changing pattern.Mei Mingxiang Faculty of Earth Sciences and Mineral Resources, China University of Geosciences, Beijing 100083 Ma Yongsheng China Petrochemical Corporation (SINOPEC), Beijing 100029 Zhou Hongrui Du Benming Luo Zhiqing Guo Qingyin Faculty of Earth Sc 2001Journal of China University of Geosciences2001,12,1:11
2急性儿茶酚胺暴露引起可逆的无心脏细胞再生的心肌细胞损伤显示文摘儿茶酚胺增加心脏收缩力,但暴露于高浓度儿茶酚胺或长时间暴露可引起心脏损伤。最近的一项研究表明,小鼠单次皮下注射异丙肾上腺素(isoproterenol,ISO;200 mg/kg)导致急性心肌细胞死亡(8%-10%),但在1个月之内心脏完整修复。心脏再生是通过内源性原癌基因蛋白质cKit+心脏干细胞介导新的心肌细胞形成。刘莉 叶鹏 Wallner M Duran JM Mohsin S Troupes CD Vanhoutte D Borghetti G Vagnozzi RJ Gross P Yu D Trappanese DM Kubo H Toib A Sharp TE Harper SC Volkert MA Starosta T Feldsott EA Berretta RM Wang T Barbe MF Molkentin JD Houser SR 2016中华高血压杂志2016,24,8:4
3印度Ganga-Meghna-Brahmaputra平原及周围地区与孟加拉国地下水砷污染及其对健康影响的19年研究显示文摘基于近19年对印度Ganga—Meghna—Brahmaputra(简称GMB)平原(面积569749km^2,人口超过5亿)地下水砷污染的调查,可以确定印度Ganga—Brahmaputra平原(包括北方邦、比哈尔邦、恰尔康得邦、西孟加拉邦、阿萨姆邦)和孟加拉国普遍受到砷的污染。近期的调查研究也表明,除米佐拉姆邦外,其他各邦的地下水也受到不同程度的砷污染。至今为止.已对印度各邦和孟加拧国的175000份和50808份压把井水样进行了含砷量检测。并组织了一支包括皮肤科、神经科和妇产科医生在内的有经验的专家组,对上述地区125000人进行了临床检查,其中9%患有砷导致的皮肤病损症状。至今共采集分析了60000份生物样品。包括发样、指甲、尿样及皮肤鳞屑,其中80%的样品含砷量超过允许值,很多人由此受到砷的亚临床损害。在上述砷暴露地区.19000名儿童经过检查,近1100人患有砷导致的皮肤病损。该调查结果表明.儿童比成人更容易受到砷的毒性损害。在这种状况下.应着力解决饮水安全问题来减轻砷的苊害.Ahamed S Hossain MA Mukharjee A Sengupta MK Das B Nayak B Pal A Mukherjee SC Pati S Dutta RN Saha KC Quamruzzaman Q Chakraborti D 付松波(译) 孙殿军(审校) 2007中国地方病学杂志2007,26,1:3
