1大堡礁和大峡谷世界遗产区的适应性管理显示文摘关于人类和环境相互关系的传统观念正在迅速改变。那种认为人类与自然是相互隔离的,自然资源是取之不尽用之不竭的,而且认为世界是稳定的、可以预测的并且是平衡的旧观点已经过时了。在动态的社会-生态景观中强调学习和灵活性管理为基础的适应性方法的新的理念框架已经迅速初现端倪。我们以两个典型的世界遗产地区(大堡礁和大峡谷)为案例来研究如何在自然资源管理中通过改善科学和社会两个方面的结合来指导多尺度管理系统的变革从而应对和处理人类越来越占据主导的世界中出现的不确定性、风险和变化。Terence P.Hughes Lance H.Gunderson Carl Folke Andrew H.Baird David Bellwood Fikret Berkes Beatrice Crona Ariella Helfgott Heather Leslie Jon Norberg Magnus Nystrm Per Olsson Henrik sterblom Marten Scheffer Heidi Schuttenberg Robert S.Steneck Maria Teng Max Troell Brian Walker James Wilson Boris Worm 丁莉 2007AMBIO-人类环境杂志2007,36,B11:4

7Rare presentation of post-transplant lymphoproliferative disorder isolated to gastroesophageal junction显示文摘Post transplant lymphoproliferative disorder (PTLD) represents a life threatening disorder occurring after transplantation, ranging from a polyclonal mononucleo- sis like illness to a monomorphic high grade neoplasm with cytologic and histopathologic evidence indica- tive of transformation to lymphoma. PTLD of diffuse large B-cell lymphoma (DLBCL) subtype, isolated to the esophagus is a rare diagnosis. We describe the first case of an immunocompromised adult patient diagnosed with DLBCL-PTLD limited to his esophagus without an associated mass or locoregional lymphade-nopathy on imaging since the institution of the revised Cheson criteria, which includes positron emission tomography-computed tomography as the standard staging modality. Even more unique to our case was the suggestion of underlying cytomegalovirus (CMV) gastritis leading to a hypothesis about a less well understood relationship between CMV and Epstein Barr virus (EBV). In the post transplant setting, im- munocompromised state, or EBV positive state, upper gastrointestinal symptoms should prompt investigation with an upper endoscopy (EGD). Additionally, specific to our case, the fact that the patients' presentation was suspicious for CMV gastritis raises the possibility that the CMV infection predated his PTLD increasing his risk of acquiring PTLD. This reemphasizes the im- portance and diagnostic utility of early screening with EGD in patients after transplantation.Brad M Haverkos Veeral M Oza Andrea Johnson Jon Walker Arwa Shana'ah 2013World Journal of Gastrointestinal Oncology2013,5,12:0
