1企业市场行为、非市场行为与竞争互动——基于中国家电行业的案例研究显示文摘传统的企业竞争互动理论主要是以市场行为为核心的研究,而在相当大的程度上忽视了非市场行为的重要性与价值。本文采用结构内容分析法,以中国家电行业企业为例,主要讨论这些企业竞争行为,尤其是市场行为与非市场行为之间的互动特征及其规律,从而将现有的以市场为核心的竞争互动研究有效地拓展到非市场领域,以期为中国企业的管理者们在预测竞争对手策略与行为选择时提供一些实践启示。田志龙 邓新明 Taeb Hafsi 2007管理世界2007,23,8:63

4Diversity of endophytes across the soil-plant continuum for Atriplex spp. in arid environments显示文摘Endophytes are hypothesized to be transferred across the soil-plant continuum, suggesting both the transfers of endophytes from environment to plant and from plant to soil. To verify this hypothesis and to assess the role of locality, we evaluated the similarity of microbial communities commonly found both in soils and endophytic communities in three arid regions, i.e. the Jornada LTER(Long Term Ecological Research) site in New Mexico, USA, and the research station of Jordan University of Science and Technology(JUST) and Khanasri research station in Badia region of Jordan. Rhizosphere and non-rhizosphere soils, leaves and seeds of Atriplex spp. were sampled. Diversity and distribution of bacteria and fungi across the soil-plant continuums were assessed by tag-encoded FLX amplicon pyrosequencing and sequence alignment. Of the total bacterial OTUs(operational taxonomic units), 0.17% in Khanasri research station, 0.16% in research station of JUST, and 0.42% in Jornada LTER site were commonly found across all the plant and soil compartments. The same was true for fungi in two regions, i.e. 1.56% in research station of JUST and 0.86% in Jornada LTER site. However, in Khanasri research station, 12.08% of total fungi OTUs were found in at least one soil compartment and one plant compartment. Putative Arthrobacter, Sporosarcina, Cladosporium and members of Proteobacteria and Actinobacteria were found across all the soil-plant continuums. Ascomycota, mainly including Didymellaceae, Pleosporaceae and Davidiellaceae were present across all the soil-plant continuums. Microbial communities in two regions of Jordan were similar to each other, but both of them were different from the Jornada LTER site of USA. SIMPER(similarity percentage) analysis of bacterial and fungal taxa for both soil and endophyte communities revealed that dissimilarities of two bacterial genera(Arthrobacter and Sporosarcina) and two fungal genera(Cladosporium and Alternaria) are very high, so they play key roles in the soil-plant continuums. A weighed Pearson correlation analysis for the specific bacterial OTUs in the soil-plant continuums only showed high similarity between the two regions of Jordan. However, fungal groups showed higher similarities among all regions. This research supports the hypothesis of continuity of certain bacterial and fungal communities across the soil-plant continuums, and also explores the influences of plant species and geographic specificity on diversity and distribution of bacteria and fungi.Mohammad E TAHTAMOUNI Sa'eb KHRESAT Mary LUCERO Jesus SIGALA Adrian UNC 2016Journal of Arid Land2016,8,2:4
5血栓素(thromboxane)合成酶抑制剂——Dazmegrel(UK38,485)对烧伤皮肤血流灌注的影响显示文摘近十年来,血栓素(thromboxane)被认为在烧伤后真皮进行性缺血过程中起重要作用,有报导前列腺素、血栓素抑制剂可改善局部血循环,从而促进深Ⅱ度烧伤刨而愈合。本实验以啄鼠深Ⅱ度烧伤模型,肌注血栓素合成酶抑制剂Dazmegrel(UK38,485或uk)3.4mg/kg/天(UK3.4mg)、10mE/kg/天(UK10mg)、或30mg/kg/天(UK30mg),使用印度墨汁灌注及UK-133(氙-133)清除试验,未发现Dazfilegrel能改善烧伤局部血流。这与有的实验结论不同,肌注Dazmegrel 3.4rag/kg/天的促进烧伤创面愈合作用,不是由于该药改善局部血流量所致。此外,Xe-133清除试验示伤后7小时深Ⅱ度烧伤皮肤血流量有一明显下降过程,伤后24小时则有一明显增加过程,如何认识及应用这一'先低后高。现象,对促进深Ⅱ度烧伤创面愈合显然是有意义的。汪仕良 黎鳌 Alexander JW Silberstein EB Robb E Lukes S Trocki O Ogle DK 邹万忠 1989中华整形烧伤外科杂志1989,5,3:3
6Eph Receptors and Ephrins in Neuron-Astrocyte Communication at Synapses显示文摘神经元-胶质细胞间的相互作用对调节脑内突触联系有重要作用。星形胶质细胞对突触的发育、维持和可塑性有特别关键、复杂的作用。同样,神经元也对星形胶质细胞的生理功能产生影响。但是,神经元和星形胶质细胞之间相互作用的分子机制尚未完全阐明。近来研究表明,Eph受体酪氨酸激酶及轴突导向因子在突触间接触依赖性神经元-胶质细胞的相互作用中起重要作用。与配体结合后,这2个细胞表面相关蛋白家族成员激活双向信号通路,调节神经元和星形胶质细胞的结构和生理特征。本综述着重探讨Eph受体酪氨酸激酶及轴突导向因子在突触间神经元-胶质细胞的相互作用中扮演的角色,并讨论其在突触可塑性、行为及疾病中的潜在作用。Murai KK Pasquale EB 2011神经损伤与功能重建2011,6,6:3
