| 1 | The first pterosaur 3-D egg:Implications for Pterodaustro guinazui nesting strategies,an Albian filter feeder pterosaur from central Argentina显示文摘The increasing number of fossil pterosaur eggs sheds light on nesting environments and breeding behaviors of these extinct flying reptiles.Here we report the first partial three-dimensional egg of the pterosaur,Pterodaustro guinazui,from central Argentina.The specimen was discovered from the same Albian deposits as the exceptional P.guinazui embryo described in 2004.Microscopic characterizations indicate a pristine preservation of the 50 mm thick calcium carbonate,which differs significantly from the soft shell of Chinese pterosaur eggs.Estimate of the eggshell conductance implies that the nest had a minimum moisture content of 75%.This moisture estimate,combined with geological and taphonomical data,suggests that P.guinazui may have adopted a nesting strategy similar to those of grebes and flamingos rather than being buried on land,as previously hypothesized.Moreover,our results demonstrate that the nesting paleoenvironment of this pterosaur species was closely linked to a mesohaline lacustrine ecosystem in a basin governed by regional tectonic subsidence,a setting characteristic for the feeding and reproduction of modern flamingos. | Gerald Grellet-Tinner Michael B.Thompson Lucas E.Fiorelli Eloísa Argaaraz Laura Codorniú E.Martín Hechenleitner | 2014 | Geoscience Frontiers2014，5，6： | 2 |
| 2 | 静脉注射曲马多与硬膜外吗啡缓解胸廓切开术后疼痛的比较:安慰剂对照的双盲试验显示文摘曲马多可以缓解术后疼痛且导致呼吸抑制的危险性很小,其镇痛作用机理仅部分在于其所具有的阿片激动剂活性,因而我们研究了曲马多对胸廓切开术后疼痛的缓解作用.在这项随机双盲的试验中,单次快速静脉注射150mg曲马多(T组)与硬膜外注射吗啡相比较,首剂量为2mg,之后按0.2mg/h的速度持续注射(M组).每组患者可以通过病人自控镇痛(PCA)泵静脉注射吗啡.手术后定时记录疼痛评分、吗啡的消耗量、动脉血气、肺活量直至术后第一天的早8:00.两组患者的疼痛都得到了充分的缓解,两组间疼痛评分和PCA吗啡消耗量没有差别.术后2小时T组的动脉氧分压(PaO2)显著高于M组,而术后4小时M组的动脉二氧化碳分压(PaCO2)显著高于T组,其他呼吸上的差异不显著.我们认为,手术结束时单次给150mg曲马多与硬膜外注射吗啡在术后早期具有相同的镇痛效果. | Michael F.M.James PhD FRCA Sylvia A.M.Heijke FFA(SA) Peter C.Gordon FFA(SA) | 2003 | 中国疼痛医学杂志2003，9，2： | 2 |
