| 1 | 盐胁迫条件下杨树组织及细胞中钾、钙、镁的变化显示文摘该文研究了NaCl对群众杨 (Populus‘popularis 35 44’ ,P .popularis)、I 2 1 4杨 (P .×euramericanacv .I 2 1 4 ,P .cv.I 2 1 4 )和胡杨 (P .euphratica) 3种杨树组织和细胞营养状况的影响 .为期 30d的盐处理降低了群众杨和I 2 1 4杨根和茎组织中K+、Ca2 +、Mg2 +的水平 ,而对于叶片营养元素的水平基本没有影响 .与群众杨和I 2 1 4杨比较 ,胡杨组织的营养水平受NaCl的影响最小 .根皮层细胞X 射线微区分析的结果显示 ,NaCl降低了群众杨和I 2 1 4杨细胞壁和液泡中K+、Mg2 +的水平 ,但对于胡杨细胞营养元素水平的影响较小 .实验结果表明 ,胡杨在盐胁迫条件下能保持对营养元素的吸收 ,维持较好的营养状况 ,这是其抗盐性强的原因之一 ;I 2 1 4杨和群众杨的抗盐性弱 。 | 陈少良 李金克 尹伟伦 王沙生 Eberhard Fritz Andrea Polle Aloys Httermann | 2002 | 北京林业大学学报2002，24，5： | 41 |
| 2 | 盐胁迫下胡杨和毛白杨叶细胞中的离子区隔化显示文摘该文以抗盐的胡杨和盐敏感的毛白杨组培再生苗为实验材料,利用X--射线微区分析技术研究盐胁迫下(为期20d的盐处理)叶片各种类型细胞内主要元素Na+、Cl-、K+的分布情况,测定的细胞类型包括:①叶脉细胞(叶脉维管束导管、叶脉维管束内部和外部的薄壁细胞);②叶肉细胞(栅栏组织、海绵组织);③表皮细胞(上、下表皮细胞).结果表明,胡杨和毛白杨叶细胞对盐离子的区隔化有明显差异:与毛白杨相比,盐处理后的胡杨叶细胞不但具有较高的拒Na+能力,即将Na+贮存在质外体中,而且液泡区隔Na+的能力也强于毛白杨.在Cl-的区隔化方面,对照处理胡杨各种类型的细胞(包括叶脉、叶肉和表皮细胞)Cl-浓度都高于毛白杨,但在盐胁迫下,胡杨叶片的细胞壁、液泡甚至叶绿体中Cl-的含量都低于毛白杨,这是胡杨根细胞限制Cl-离子根冠运输的结果.盐处理使胡杨叶片各种类型细胞中的K+浓度降低;与胡杨不同,毛白杨叶片细胞中质外体的K+浓度下降,而液泡中的K+水平却相应提高,这是毛白杨细胞内K+重新分配的结果:由于盐处理后毛白杨液泡内积累了过多的Cl-,K+从细胞壁进入液泡,用以平衡液泡内Cl-积累所带来的负电荷. | 戴松香 陈少良 Eberhard Fritz Andrea Olbrich Christine Kettner Andrea Polle Aloys Hüttermann | 2006 | 北京林业大学学报2006，28，S2： | 14 |
| 3 | 干旱胁迫下胡杨生理适应机制的研究显示文摘胡杨具有很强的抗旱能力,是生长在沙漠地区少有的乔木树种,在我国主要分布于新疆的塔克拉玛干沙漠.为了更深入阐明胡杨的抗旱机制,我们对生长在新疆塔克拉玛干沙漠的天然胡杨林进行了实地调查、现场采样和室内相关实验.结果表明,在干旱胁迫下,胡杨叶片的蒸腾作用减少,气孔阻力增加.严重干旱胁迫后,叶片中的K+和Ca2+含量增加,分别为对照的1·43倍和2·99倍,而Mg2+和Na+变化不明显.和对照相比,中度干旱胁迫下胡杨叶片质膜H+--ATPase的质子转运活性没有差别,但严重干旱胁迫则使其活性降低,质膜H+--ATPase转运质子的能力下降.以上结果表明,胡杨可通过增加气孔阻力来降低胡杨叶片的蒸腾作用,选择性的吸收无机离子以及降低ATP消耗来适应干旱环境的胁迫. | 杨永青 王文棋 Erio A.Ottow 兰海燕 张富春 Andrea Polle 蒋湘宁 | 2006 | 北京林业大学学报2006，28，S2： | 14 |
| 4 | 钠盐和氯盐胁迫下胡杨木质部汁液ABA、离子浓度和叶片气体交换的变化(英文)显示文摘研究了渗透胁迫和盐胁迫下一年生胡杨 (PopuluseuphraticaOliv.)幼苗的木质部汁液脱落酸 (ABA)、离子浓度及叶片气体交换的变化。PEG 6 0 0 0 (溶液渗透势 - 0 .2 4MPa)、5 0mmol/L含钠离子的盐溶液 (NaNO3 ∶NaHCO3 ∶NaH2 PO4=5∶4∶1,pH 6 .8,渗透势 - 0 .2 4MPa)和 5 0mmol/L含氯离子的盐溶液 (KCl∶NH4Cl=1∶1,渗透势 - 0 .2 4MPa) 3种处理都显著降低了苗木的净光合速率 (Pn)和蒸腾速率 (TRN) ,但盐处理植株的TRN高于PEG处理的苗木。木质部汁液ABA的浓度在PEG处理后 1h达到峰值 ,之后开始下降 ,降到对照水平后又逐渐回升。盐处理苗木的ABA也是在处理开始后就迅速升高 ,但之后ABA水平明显高于PEG处理的植株。结果显示 ,渗透胁迫和离子胁迫都能提高胡杨木质部汁液ABA的浓度 :盐处理开始后ABA的迅速升高主要是渗透胁迫的作用 ,而此后离子胁迫 (Na+ 和Cl-)对ABA水平的提高具有重要作用。钠盐处理对胡杨净光合速率和蒸腾速率的抑制作用高于氯盐处理 ,其木质部汁液中较高水平的ABA和盐离子 (Na+ 和Cl-)是可能的原因。钠盐处理苗木的盐离子 (Na+ 和Cl-)水平高于氯盐处理 ,主要是由以下两方面的原因所致 :(1)细胞膜上的Ca2 + 被Na+ 所取代 ,增加了膜的透性 ;(2 )胡杨根细胞液泡对Na+ 的区隔化能力较弱 (与? | 陈少良 李金克 王天华 王沙生 Andrea POLLE Aloys HüTTERMANN | 2003 | Acta Botanica Sinica2003，45，5： | 8 |
| 5 | sTREM-1 is a specific biomarker of TREM-1 pathway activation显示文摘TREM-1(triggering receptor expressed on myeloid cells-1)is a transmembrane receptor expressed by innate immune cells,including endothelial cells and platelets.TREM-1 is a crucial mediator of septic shock that acts by synergizing with Toll-like receptors(TLRs)to amplify the inflammatory responses to pathogens,thus promoting sepsis-induced immune dysregulation and organ dysfunction[1,2,3]. | Lucie Jolly Kévin Carrasco Margarita Salcedo-Magguilli Jean-Jacques Garaud Simon Lambden Tom van der Poll Alexandre Mebazaa Pierre-François Laterre Sebastien Gibot Amir Boufenzer Marc Derive | 2021 | Cellular & Molecular Immunology2021，18，8： | 8 |
| 6 | Grease film evolution in rolling elastohydrodynamic lubrication contacts显示文摘Although most rolling element bearings are grease lubricated,the underlying mechanisms of grease lubrication has not been fully explored.This study investigates grease film evolution with glass disc revolutions in rolling elastohydrodynamic lubrication(EHL)contacts.The evolution patterns of the grease films were highly related to the speed ranges and grease structures.The transference of thickener lumps,film thickness decay induced by starvation,and residual layer were recognized.The formation of an equilibrium film determined by the balance of lubricant loss and replenishment was analyzed.The primary mechanisms that dominate grease film formation in different lubricated contacts were clarified. | Xinming LI Feng GUO Gerhard POLL Yang FEI Ping YANG | 2021 | Friction2021，9，1： | 7 |
| 7 | Mesenchymal stem cells as a therapeutic tool to treat sepsis显示文摘Sepsis is a clinical syndrome caused by a deregulated host response to an infection. Sepsis is the most frequent cause of death in hospitalized patients. Although knowledge of the pathogenesis of sepsis has increased substantially during the last decades, attempts to design effective and specific therapiestargeting components of the derailed host response have failed. Therefore, there is a dramatic need for new and mechanistically alternative therapies to treat this syndrome. Based on their immunomodulatory properties, adult mesenchymal stem or stromal cells(MSCs) can be a novel therapeutic tool to treat sepsis. Indeed, MSCs reduce mortality in experimental models of sepsis by modulating the deregulated inflammatory response against bacteria through the regulation of multiple inflammatory networks, the reprogramming of macrophages and neutrophils towards a more antiinflammatory phenotype and the release of antimicrobial peptides. This report will review the current knowledge on the effects of MSC treatment in preclinical experimental small animal models of sepsis. | Eleuterio Lombardo Tom van der Poll Olga Dela Rosa Wilfried Dalemans | 2015 | World Journal of Stem Cells2015，7，2： | 6 |

| 9 | Effect of NaCl on growth and ion relations in two salt-tolerant strains of Paxillus involutus显示文摘The effect of NaCl on growth,biomass and ion relations of two salt-tolerant isolates of Paxillus involutus,MAJ and NAU were investigated.The two Paxillus strains were exposed to the following concentrations of NaCl:0,100,200 and 500 mmol·L-1.Growth of MAJ and NAU was enhanced by 100 mmol·L-1 NaCl but severely inhibited at the concentration of 500 mmol·L-1.NAU exhibited a greater capacity to exclude Na+ and Clunder all salinity levels,whereas the salt-includer MAJ had a higher capacity in nutrient uptake under salt stress.The ratios Na+/K+,Na+/Ca2+ and Na+/Mg2+ in NaCl-treated MAJ and NAU did not increase at levels of 100 and 200 mmol·L-1 NaCl but markedly increased at 500 mmol·L-1.This suggests that the two strains,especially MAJ,enhanced nutrient uptake corresponding to the increased Na+ influx at moderate salinity.We conclude that both MAJ and NAU are able to tolerate 500 mmol·L-1 NaCl but there are species-specific differences in retaining ionic homeostasis in the two Paxillus strains.NAU is a salt-excluder,MAJ is a salt-includer but retains a high capacity in nutrient selectivity under saline conditions.Their definite mechanisms to enhance salt tolerance of mycorrhizal hosts need further study. | ZHANG Hua LI Jing CHEN Shao-liang LU Cun-fu WANG Rui-gang DAI Song-xiang ZHU Hui-juan ZHANG Yun-xia SHI Yong WANG Mei-juan LU Yan-jun LI Li-si Rosemarie LANGENFELD-HEYSER Fritz EBERHARD Andrea POLLE | 2008 | Forestry Studies in China2008，10，2： | 3 |
| 10 | National Forest Inventories capture the multifunctionality of managed forests in Germany显示文摘Background:Forests perform various important ecosystem functions that contribute to ecosystem services.In many parts of the world,forest management has shifted from a focus on timber production to multi-purpose forestry,combining timber production with the supply of other forest ecosystem services.However,it is unclear which forest types provide which ecosystem services and to what extent forests primarily managed for timber already supply multiple ecosystem services.Based on a comprehensive dataset collected across 150 forest plots in three regions differing in management intensity and species composition,we develop models to predict the potential supply of 13 ecosystem services.We use those models to assess the level of multifunctionality of managed forests at the national level using national forest inventory data.Results:Looking at the potential supply of ecosystem services,we found trade-offs(e.g.between both bark beetle control or dung decomposition and both productivity or soil carbon stocks)as well as synergies(e.g.for temperature regulation,carbon storage and culturally interesting plants)across the 53 most dominant forest types in Germany.No single forest type provided all ecosystem services equally.Some ecosystem services showed comparable levels across forest types(e.g.decomposition or richness of saprotrophs),while others varied strongly,depending on forest structural attributes(e.g.phosphorous availability or cover of edible plants)or tree species composition(e.g.potential nitrification activity).Variability in potential supply of ecosystem services was only to a lesser extent driven by environmental conditions.However,the geographic variation in ecosystem function supply across Germany was closely linked with the distribution of main tree species.Conclusions:Our results show that forest multifunctionality is limited to subsets of ecosystem services.The importance of tree species composition highlights that a lack of multifunctionality at the stand level can be compensated by managing forests at the landscape level,when stands of complementary forest types are combined.These results imply that multi-purpose forestry should be based on a variety of forest types requiring coordinated planning across larger spatial scales. | Nadja K.Simons María R.Felipe-Lucia Peter Schall Christian Ammer Jürgen Bauhus Nico Blüthgen Steffen Boch François Buscot Markus Fischer Kezia Goldmann Martin M.Gossner Falk Hänsel Kirsten Jung Peter Manning Thomas Nauss Yvonne Oelmann Rodica Pena Andrea Polle Swen C.Renner Michael Schloter Ingo Schöning Ernst-Detlef Schulze Emily F.Solly Elisabeth Sorkau Barbara Stempfhuber Tesfaye Wubet Jörg Müller Sebastian Seibold Wolfgang W.Weisser | 2021 | Forest Ecosystems2021，8，1： | 2 |
