Species distribution models a.e used to a.d our understa.ding of the processes driving the spa.ia. pa.terns of species’ ha.ita.s. This a.proa.h ha. received criticism, however, la.gely beca.se it neglects la.dsca.e metrics. We exa.ined the rela.ive impa.ts of la.dsca.e predictors on the a.cura.y of ha.ita. models by constructing distribution models a. regiona. sca.es incorpora.ing environmenta. va.ia.les (clima.e, topogra.hy, vegeta.ion, a.d soil types) a.d seconda.y species occurrence da.a. a.d using them to predict the occurrence of 36 species in 15 forest fra.ments where we conducted ra.id surveys. We then selected six la.dsca.e predictors a. the la.dsca.e sca.e a.d ra. genera. linea. models of species presence/a.sence with either a.single sca.e predictor (the proba.ilities of occurrence of the distribution models or la.dsca.e va.ia.les) or multiple sca.e predictors (distribution models + one la.dsca.e va.ia.le). Our results indica.ed tha. distribution models a.one ha. poor predictive a.ilities but were improved when la.dsca.e predictors were a.ded; the species responses were not, however, simila. to the multiple sca.e predictors. Our study thus highlights the importa.ce of considering la.dsca.e metrics to genera.e more a.cura.e ha.ita. suita.ility models.

目的:研究当归多糖(a.S)对小鼠骨髓单个核细胞的保护作用。方法:将60只Ba.B/c小鼠随机分为对照组、100μg/mL、200μg/mL、300μg/mL和400μg/mL a.S组(n=12)。采用密度梯度离心法分离骨髓单个核细胞;各组细胞中分别加入适量冻存液(含10... 详细信息

目的:研究当归多糖(a.S)对小鼠骨髓单个核细胞的保护作用。方法:将60只Ba.B/c小鼠随机分为对照组、100μg/mL、200μg/mL、300μg/mL和400μg/mL a.S组(n=12)。采用密度梯度离心法分离骨髓单个核细胞;各组细胞中分别加入适量冻存液(含10%二甲基亚砜、10%胎牛血清、80%DMem培养液)及相应浓度a.S,于液氮中(-196℃)保存6个月。细胞复苏后分别观察各组细胞的形态,检测细胞活力及回收率;流式细胞术检测细胞周期;酶联免疫吸附实验检测细胞凋亡及冻存液中丙二醛含量的变化。结果:与对照组相比,药物组均能提高骨髓单个核细胞的活力及回收率;降低细胞凋亡数量及冻存液中丙二醛的含量;其中200μg/mL组保护效果最佳。结论:a.S对小鼠骨髓单个核细胞具有保护作用,其保护机制可能是通过减轻膜的氧化应激反应,降低细胞凋亡来实现的。

在本教程综述中,我们重新阐述和表达了镧系离子间无辐射能量传递(ET)速率的理论形式,并且强调了考虑镧系离子本身特异性所引发的与Förster和Dexter理论不同之处。所给出的表达式遵循了Judd-Ofelt的4f-4f跃迁理论框架之下的Kushida.法,并计入了如下电多极机制:偶极-偶极(W_(d-d))、偶极-四极(W_(d-q))和四极-四极(W_(q-q))。更为重要的是,当前的机制也扩展包括了交换(W_(ex))和磁偶极子-磁偶极子(W_(md-md))作用,并经过改进进一步包含了屏蔽效应以及给出了F因子(费米黄金规则中的态密度)的解析表达式。与Kushida.原始方法类似,我们只考虑了强制电偶极子(FED)对Judd-Ofelt强度参数的贡献,并细节性地讨论了磁偶极-磁偶极相互作用的选择定则以及相关矩阵元的计算。此外,我们还以Tb(Ⅲ)-Eu(Ⅲ)和Yb(Ⅲ)-Er(Ⅲ)的能量传递速率计算为例,逐步展示了计算过程、主要的计算支撑信息以及所使用的计算脚本。
