Some Properties of Completely Arithmetical Rings

引用

Algebra Colloquium 2016年第1期23卷 83-88页

作者： xinmin lu School of Science Nanjing University of Science and Technology Nanjing 210093 Ghina

In this paper, we introduce the concept of completely arithmetical rings and investigate their properties. In particular, we prove that if R is a completely arithmetical ring with J（R） =0, then Ko（R） ≌Z^n for some positive integer n. We also show that such a ring is precisely a ring in which every proper ideal can be written uniquely as a product of finitely many distinct completely strongly irreducible ideals.

目的研究牡蛎多糖缓解体力疲劳的功能及对力竭小鼠肠道菌群结构和多样性的调节作用。方法以总抗氧化、清除DPPH自由基、抑制超氧阴离子自由基和羟自由基能力为指标,分析抗氧化活性;采用共孵育法,以大肠埃希菌和金黄色葡萄球菌为指示菌分析抑菌活性;选取SPF级8周龄Balb/c小鼠,分别给予纯净水以及低[200 mg/(kg·mb)]、中[400 mg/(kg·mb)]、高[800 mg/(kg·mb)]剂量牡蛎多糖,持续口服干预5周,以小鼠负重游泳时间以及血乳酸、血尿素氮、肝糖原为指标测定其缓解体力疲劳功能,采集力竭小鼠盲肠内容物进行16S rDNA高通量测序,分析肠道菌群组成与多样性。结果牡蛎多糖具有较好的抗氧化和抑菌活性,且与其浓度呈正相关。牡蛎多糖具有缓解体力疲劳功能,以高剂量效果最为显著。牡蛎多糖干预可影响肠道菌群的组成,高剂量组与对照组的beta多样性存在差异;两组间群落结构差异显著,高剂量组中Muribaculaceae的相对丰度显著增加,另枝菌属(Alistipes)、拟普雷沃菌属(Alloprevotella)、颤螺旋菌属(Oscillibacter)相对丰度也更高;线性判别分析差异贡献证实Alistipes在高剂量组中差异显著,发挥了重要作用。结论牡蛎多糖具有较好的抗氧化和抑菌活性,可缓解体力疲劳功能,且能调节小鼠肠道菌群结构和beta多样性,促进有益菌属而抑制有害菌属的生长,可为后续研发牡蛎多糖精准营养功效食品提供参考依据。

植物能够调控土壤生物群落,而后者将对后期发生的植物适合度和群落结构产生显著影响。长期种植的单一农作物能够显著调控土壤生物群落,而新近荒废农田中土壤生物如何调控外来和本土杂草定植目前还不清楚,这严重束缚了农田杂草治理能力的提升。本研究采集新近荒废的玉米地表层土壤,选取58种华中地区常见农田杂草(28种外来和30种本土植物)为对象开展实验。通过将植物种植于伽马射线灭菌或未灭菌土壤,定量评价了土壤生物对植物地上、地下和总生物量的影响,探讨了实验物种-玉米系统发育距离和土壤效应是否相关,探究了能够预测土壤效应的关键植物性状。结果发现:(i)总体而言,土壤生物显著抑制实验植物生长,表明土壤拮抗生物(如病原菌等)发挥主导作用;(ii)伴随植物生长潜力提升,土壤生物对植物的抑制作用逐渐增强,而土壤生物对实验植物的调控作用与实验物种-玉米系统发育距离无关;(iii)相对于本土植物,外来植物(尤其多年生物种)被土壤生物抑制的程度更高。这些结果表明,植物生长潜力能够有效预测土壤生物对植物生长的调控作用,而且新近荒废农田土壤生物具有抵御外来植物入侵的潜力。

The rats were given panaxatriol intraperitoneally once a day (5mg/day) for 14 days beginning from 24 h before the irradiation. The results showed that hypothalamic L-Enk (Plus panaxatriol groups. These suggest thhat panaxatriol may weaken the decrement of hypothalamic and pituitary opioid peptide contents, testicular cAMP content and serum TS level and the increment of serum FSH level after the rats being irradiated, and that panaxatriol may have protective fu

理解入侵生物的繁殖策略是阐明生物入侵机制的一个重要方面。入侵植物常表现出一些共同的繁殖特征,如以两性花为主的性系统、自动自交为主的繁育系统或不依赖传粉媒介的无融合生殖和无性繁殖以及高生殖投资的资源配置策略等。成功入侵的外来植物通过影响本土的传粉者,在种群和群落水平上影响本土植物的有性繁殖,甚至促使某些本土植物在繁殖对策和表型性状上发生快速转变。目前,入侵植物繁殖策略及其生态效应的研究多侧重于入侵种的快速演化,而有关外来植物与本土植物间的相互影响及其可能存在的协同适应研究还较为缺乏。探讨本土植物在外来种入侵压力下的繁殖对策和响应机制,将丰富人们对物种间竞争、共存及群落构建等机制的深入了解。从繁殖和适应的角度探求入侵植物与本土植物之间的复杂关系,将有助于解析生物入侵的机制及人类干扰下的物种演化规律,也为预测和防控入侵植物提供科学依据。
