镉对灵芝菌丝抗氧化系统的影响

应用生态学报 , 2008,
Abstract: 研究了不同浓度镉(cd)(0、10、50、100、200和400μmol·l-1)对灵芝菌丝抗氧化系统的影响.结果表明,随着cd浓度增加,菌丝鲜质量、脯氨酸、总糖和还原糖含量逐渐下降,非蛋白巯基化合物(npt)水平逐渐上升,当cd浓度达到400μmol·l-1时,npt含量急剧上升至对照组的6.7倍.在试验浓度范围内,灵芝菌丝体过氧化物酶(pod)、谷胱甘肽还原酶(gr)和过氧化氢酶(cat)活性呈显先上升后下降的变化趋势,并均在cd浓度为100μmol·l-1时达峰值;超氧化物歧化酶(sod)和脂氧合酶(lox)活性则随着cd浓度的增加而逐渐上升,在cd浓度为400μmol·l-1时达峰值.采用聚丙烯酰胺凝胶电泳分析cd胁迫下灵芝菌丝抗氧化酶的同工酶谱发现,100~400μmol·l-1cd处理诱导出2条mn-sod型同工酶带;10~200μmol·l-1浓度cd上调组成型cat、sod、pod和lox同工酶的表达强度;而400μmol·l-1cd的则显著抑制了pod同工酶的表达.

Abstract: The study on the effects of different concentration (0, 10, 50, 100, 200 and 400 micromol x L(-1)) cadmium (Cd) on the antioxidative system in Ganoderma lucidum mycelia indicated that with increasing concentration of Cd, the fresh mass and the proline, total polysaccharides, and reduced polysaccharides contents of G. lucidum mycelia decreased, but non-protein thiol (NPT) content increased. At 400 micromol x L(-1) of Cd, the NPT content increased dramatically, being 5.7 times higher than control. Within the range of test Cd concentrations, the activities of CAT, GR and POD increased first and decreased then, with the peak at 100 micromol x L(-1) of Cd, while the activities of LOX and SOD increased with increasing Cd concentration, with the maximum at 400 micromol x L(-1) of Cd. Polyacrylamide gel electrophoresis analysis revealed that 100-400 micromol x L(-1) of Cd induced two additional isozymes bands of Mn-SOD, 10-200 micromol x L(-1) of Cd increased the intensity of constitutive isozymes of CAT, POD, SOD and LOX, while 400 micromol x L(-1) of Cd decreased the intensity of isozymes of POD significantly.

副词“够”和“怪”的主观性和主观化比较分析
The Comparative Analysis of the Subjectivity and Subjectivisation of Adverbs “Gou” (够) and “Guai” (怪)
 [PDF]


Modern Linguistics (ML) , 2014, DOI: 10.12677/ML.2014.21005
Abstract:
本文尝试对副词“够”和“怪”的主观性意义、主观化机制和主观化程度进行探讨,基于语料库,通过对比的方法发现,二者都能表示说话人认为具有较高的程度和出乎意料的情感,但“够”具有一定的距离感,而“怪”则表现出了一定程度的亲近和接纳。在各自的主观化过程中,词语本身的意义、语境的影响以及人们的普遍认知心理都发挥了重要的作用,是形成二者不同的主观性意义的深层原因。通过对二者在句法和篇章上的不同表现,文章还证明了“够”的主观化程度比“怪”高。
The essay tries to discuss the subjective meanings, the mechanisms and degree of subjectivisation of “gou” () and “guai” (). Based on the corpus, the essay draws the conclusions by using a comparative approach: both words express the meaning that the speaker believes that something has reached a high degree and some outer-expectation. “Gou” () expresses a sense of distance between the speaker and the object while “guai” () expresses a degree of acceptance. During the course of the subjectivisation, the meaning of the words, the context in which the words often occur and cognitive and pragmatic rules of people all play important roles, and these are the underlying reasons of formation of the two different subjective meanings. Besides, the essay believes that the subjectivity of “gou” () is higher than that of “guai” () through the evidences from syntax and text.

Abstract:
本论文的目的是研究由可加分布朗运动驱动的随机偏微分方程中漂移系数的假设检验问题,其中Hurst系数为H∈[?21,1)。并且我们利用对数似然比的中偏差原理,在维数N固定,时间T趋于无穷的情况下,给出了未知参数的拒绝域和两类错误的衰减速度。最后我们将结果应用在几个例子当中。
In this paper, we focus our attention on the hypothesis testing problem for the drift coefficient in the diagonalizable stochastic evolution equation driven by additive fractional Brownian motion with Hurst parameter H∈[?21,1);. And when the dimension N is fixed and observation time T tends to infinity, with the help of moderate deviations for the log-likelihood ratio process, we give the negative regions and obtain the decay rates of the error probabilities. Moreover, we also apply our results to some examples.
