Periodontitis is a chronic infectious disease characterized by plaque biofilm as its main pathogenic factor;its clinical manifestations include gingival inflammation,alveolar bone resorption,attachment loss,and periodontal pocket formation,all of which eventually lead to tooth loss and seriously affect the quality of life of patients[1].This illness has a close relationship with blood sugar levels in patients with diabetes and is one of the most important complications of diabetes[2].Macrophages are an important part of host immune responses and exhibit powerful functions of identifying,phagocytizing,and removing bacteria;macrophage polarization is involved in the pathogenesis of periodontitis[3].

A novel micro-vibration sensitive-type high-damping AI matrix composites reinforced with Li7-xLa3Zr2-xNbxO12 （LLZNO, x = 0.25） was designed and prepared using an advanced spark plasma sintering （SPS） technique. The damping capacity and mechanical properties of LLZNO/AI composites （LLZNO content： 0-40 wt.%） were found to be greatly improved by the LLZNO addition. The maximum damping capacity and the ultimate tensile strength （UTS） of LLZNO/AI composite can be respectively up to 0.033 and 101.2 MPa in the case of 20 wt.% LLZNO addition. The enhancement of damping and mechanical properties of the composites was ascribed to the intrinsic high-damping capacity and strengthening effects of hard LLZNO particulate. This investigation provides a new insight to sensitively suppress micro-vibration of payloads in the aerospace environment.

时间顺序信息作为记忆项目之间的重要联结要素之一,易受到情绪的干扰。本研究通过3项实验探究编码方式与叙事连贯性是否以及如何调节情绪对于时间顺序记忆的干扰。实验1采用2(编码方式:叙事编码/离散编码)×3(情绪类型:正性/负性/中性)的混合实验设计,其中编码方式为被试间变量,探究编码方式是否能调节图片材料中情绪信息对时间顺序记忆的干扰。结果显示,在离散编码组,负性情绪条件下的时间顺序记忆正确率显著比其他两种条件低;相反,在叙事编码组,三种情绪类型下的时间顺序记忆没有显著差异。实验2采用两种情绪类型(中性和负性)的词语刺激,检验编码方式对时间顺序记忆的影响是否跨材料具有普适性。实验3通过操纵项目之间的叙事连贯性程度,进一步探究上述效应是否依赖于项目间连贯性程度。结果显示,上述叙事编码效应仅在项目之间具有高连贯性时出现。本研究不仅发现了叙事编码对于情绪记忆中时间信息的保持机制,还指明了叙事编码效应中连贯性程度的重要性。

In this paper the coherent-state approximation （CA） method is used to deal with the problem of the decoherence of the entangled states of two two-state systems. As the base of the discussion, the dissipation of one two-state system has been investigated at first. The improved results calculated by CA are given in the paper. It is shown that the right approaching behavior and scaling law have been obtained when CA is applied to the problem of dissipation of two two-state systems coupled with environment. The whole evolution process and calculated results of the decoherence of the entangled states show also the scaling law, right approaching behavior, and rich phenomenon.

Lily(Lilium spp.) is an important ornamental flower, which is mainly propagated by bulbs. Cell wall invertases(CWINs), which catalyze the irreversibly conversion of sucrose into glucose and fructose in the extracellular space, are key enzymes participating in sucrose allocation in higher plants. Previous studies have shown that CWINs play an essential role in bulblet initiation process in bulbous crops, but the underlying molecular mechanism remains unclear. Here, a CWIN gene of Lilium brownii var. giganteum(Lbg) was identified and amplified from genomic DNA. Quantitative RT-PCR assays revealed that the expression level of LbgCWIN1 was highly upregulated exactly when the endogenous starch degraded in non-sucrose medium during in vitro bulblet initiation in Lbg. Phylogenetic relationship, motif, and domain analysis of LbgCWIN1 protein and CWINs in other plant species showed that all sequences of these CWIN proteins were highly conserved. The promoter sequence of LbgCWIN1 possessed a number of alpha-amylase-, phytohormone-, light-and stress-responsive cis-elements. Meanwhile, β-glucuronidase(GUS) assay showed that the 459 bp upstream fragment from the translational start site displayed maximal promoter activity. These results revealed that LbgCWIN1 might function in the process of in vitro bulblet initiation and be in the response to degradation of endogenous starch.
