1自然保护区、恢复力和动态景观显示文摘在这个日益被人类活动所改变的世界里,保护生物多样性对于维持有恢复力的生态系统和确保生态系统产品的可持续流动以及对社会的服务是至关重要的。但是,现有的自然保护区和国家公园不大可能结合生态系统的长期和大尺度的动态。因此,保护策略必须包括大面积的人类利用经营的土地。为了能使生态系统在大规模的自然和人为干扰之后得以重组,以生态存储形式出现的空间恢复力是必备的前提。生态存储包括那些能使生态系统得以重组的物种、相互作用和结构,它的组成部分可能出现在干扰斑块中,也可能出现在周围的景观中。现有的静态自然保护区应该由动态自然保护区加以补充,例如生态休闲地和动态演替保护区,这些都是在景观尺度上模拟自然干扰状况,进行生态系统经营的组成部分。Janne Bengtsson Per Angelstam Thomas Elmqvist Urban Emanuelsson Carl Folke Margareta Ihse Fredrik Moberg Magnus Nystrm 王胜 2003AMBIO-人类环境杂志2003,32,6:11
2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
3In Situ Etching for Total Control Over Axial and Radial Nanowire Growth显示文摘We report a method using in situ etching to decouple the axial from the radial nanowire growth pathway,independent of other growth parameters.Thereby a wide range of growth parameters can be explored to improve the nanowire properties without concern of tapering or excess structural defects formed during radial growth.We demonstrate the method using etching by HCl during InP nanowire growth.The improved crystal quality of etched nanowires is indicated by strongly enhanced photoluminescence as compared to reference nanowires obtained without etching.Magnus T.Borgström Jesper Wallentin Johanna Trägårdh Peter Ramvall Martin Ek LReine Wallenberg Lars Samuelson Knut Deppert 2010Nano Research2010,3,4:4

6Serotonin type 3 receptor subunit gene polymorphisms associated with psychosomatic symptoms in irritable bowel syndrome:A multicenter retrospective study显示文摘BACKGROUND Single-nucleotide polymorphisms(SNPs)of the serotonin type 3 receptor subunit(HTR3)genes have been associated with psychosomatic symptoms,but it is not clear whether these associations exist in irritable bowel syndrome(IBS).AIM To assess the association of HTR3 polymorphisms with depressive,anxiety,and somatization symptoms in individuals with IBS.METHODS In this retrospective study,623 participants with IBS were recruited from five specialty centers in Germany,Sweden,the United States,the United Kingdom,and Ireland.Depressive,anxiety,and somatization symptoms and sociodemographic characteristics were collected.Four functional SNPs—HTR3A c.-42C>T,HTR3B c.386A>C,HTR3C c.489C>A,and HTR3E c.*76G>A—were genotyped and analyzed using the dominant and recessive models.We also performed separate analyses for sex and IBS subtypes.SNP scores were calculated as the number of minor alleles of the SNPs above.The impact of HTR3C c.489C>A was tested by radioligand-binding and calcium influx assays.RESULTS Depressive and anxiety symptoms significantly worsened with increasing numbers of minor HTR3C c.489C>A alleles in the dominant model(F_(depressive)=7.475,P_(depressive)=0.006;F_(anxiety)=6.535,P_(anxiety)=0.011).A higher SNP score(range 0-6)was linked to a worsened depressive symptoms score(F=7.710,P-linear trend=0.006)in IBS.The potential relevance of the HTR3C SNP was corroborated,showing changes in the expression level of 5-HT3AC variant receptors.CONCLUSION We have provided the first evidence that HTR3C c.489C>A is involved in depressive and anxiety symptoms in individuals with IBS.The SNP score indicated that an increasing number of minor alleles is linked to the worsening of depressive symptoms in IBS.Sabrina Berens Yuanjun Dong Nikola Fritz Jutta Walstab Mauro D'Amato Tenghao Zheng Verena Wahl Felix Boekstegers Justo Lorenzo Bermejo Cristina Martinez Stefanie Schmitteckert Egbert Clevers Felicitas Engel Annika Gauss Wolfgang Herzog Robin Spiller Miriam Goebel-Stengel Hubert Mönnikes Viola Andresen Frieling Thomas Jutta Keller Christian Pehl Christoph Stein-Thöringer Gerard Clarke Timothy G Dinan Eamonn M Quigley Gregory Sayuk Magnus Simrén Jonas Tesarz Gudrun Rappold Lukas van Oudenhove Rainer Schaefert Beate Niesler 2022World Journal of Gastroenterology2022,28,21:2
7Redundancy and Response Diversity of Functional Groups:Implications for the Resilience of Coral Reefs显示文摘对多尺度功能群生物多样性的深入了解有助于珊瑚礁管理的加强。本文主要分析了功能群内多样性在保护有利于珊瑚礁状况复原的重要生态系统过程中的作用。对于与生态系统复原有关的两个重要的物种多样性指标:功能丰余性和功能群内对变化的反应多样性进行了分析,采用了三个重要的功能群来演示这两个指标之间的相互关系.以及它们在珊瑚礁复原过程中的作用:虫黄藻(珊瑚虫的共生微藻)、造礁珊瑚和草食动物。对功能丰余性和反应多样性破坏的后果进行了进一步研究,对保护珊瑚礁复原过程中关键的生态过程策略进行了探讨。Magnus Nystrǒm 梁虹(译) 2006AMBIO-人类环境杂志2006,35,1:2
8Fecal stream diversion and mucosal cytokine levels in collagenous colitis:A case report显示文摘In this case report, we examined the levels of cytokines expressed before and during fecal stream diversion and after intestinal continuity was restored in a patient with collagenous colitis. We report the case of a46-year-old woman with chronic, active collagenous colitis who either failed to achieve clinical remission or experienced adverse effects with the following drugs:loperamide, cholestyramine, budesonide, methotrexate and adalimumab. Due to the intractable nature of the disease and because the patient was having up to 15 watery bowel movements per day, she underwent a temporary ileostomy. Colonic biopsies were analyzed for mucosal cytokine protein levels before and during fecal stream diversion and after intestinal continuity was restored. Mucosal protein levels of interleukin(IL)-1β,IL-2, IL-6, IL-12, IL-17 A, IL-23, TNF, IFN-γ, IL-4, IL-5,IL-10 and IL-13 were all higher during active disease and decreased to non-detectable or considerably lower levels during fecal stream diversion. One month after the restoration of bowel continuity, when the patient experienced a relapse of symptoms, IL-2, IL-23 and IL-21 levels were again increased. Our results indicate that fecal stream diversion in this patient suppressed the levels of all cytokines analyzed in colonic biopsies. With the recurrence of clinical symptoms and histological changes after bowel reconstruction,the levels of primarily proinflammatory cytokines increased. Our findings support the hypothesis that a luminal factor triggers the inflammation observed in collagenous colitis.Niki Daferera Ashok Kumar Kumawat Elisabeth Hultgren-Honquist Simone Ignatova Magnus Strom Andreas Münch 2015World Journal of Gastroenterology2015,21,19:2
