Kiwifruit(Actinidia spp.)plants produce economically important fruits containing abundant,balanced phytonutrients with extraordinarily high vitamin C *** the release of the first kiwifruit reference genome sequence in 2013,large volumes of genome and transcriptome data have been rapidly accumulated for a handful of kiwifruit *** efficiently store,analyze,integrate,and disseminate these large-scale datasets to the research community,we constructed the Kiwifruit Genome Database(KGD;http://***/).The database currently contains all publicly available genome and gene sequences,gene annotations,biochemical pathways,transcriptome profiles derived from public RNA-Seq datasets,and comparative genomic analysis results such as syntenic blocks and homologous gene pairs between different kiwifruit genome assemblies.A set of user-friendly query interfaces,analysis tools and visualization modules have been implemented in KGD to facilitate translational and applied research in kiwifruit,which include JBrowse,a popular genome browser,and the NCBI BLAST sequence search *** notable tools developed within KGD include a genome synteny viewer and tools for differential gene expression analysis as well as gene ontology(GO)term and pathway enrichment analysis.

The hot deformation characteristics of as-forged Ti−3.5Al−5Mo−6V−3Cr−2Sn−0.5Fe−0.1B−0.1C alloy within a temperature range from 750 to 910℃and a strain rate range from 0.001 to 1 s^(-1) were investigated by hot compression *** stress−strain curves show that the flow stress decreases with the increase of temperature and the decrease of strain *** microstructure is sensitive to deformation *** dynamic recrystallization(DRX)grains appear while the temperature reaches 790℃at a constant strain rate of 0.001 s^(-1) and strain rate is not higher than 0.1 s^(-1) at a constant temperature of 910℃.The work-hardening rateθis calculated and it is found that DRX prefers to happen at high temperature and low strain *** constitutive equation and processing map were *** average activation energy of the alloy is 242.78 kJ/mol and there are few unstable regions on the processing map,which indicates excellent hot *** the strain rate of 0.1 s^(-1),the stress−strain curves show an abnormal shape where there are two stress peaks *** can be attributed to the alternation of hardening effect,which results from the continuous dynamic recrystallization(CDRX)and the rotation of DRX grains,and dynamic softening mechanism.

This article explores the mechanisms of acupuncture meridians by determining characteristics of the tissue fluid flow in the connective tissue along meridians. Based on deep dissection of acupoints on the upper and lower limbs of the human body and micro and macro observation and measurement, a mathematical model of the flow of tissue fluid in interosseous membranes is constructed. It is shown that the signal transmission along acupuncture meridians may be determined by unique anatomical and physiological factors that govern the flow of tissue fluid in the connective tissue and involve mast cell degranulation. Our results provide a preliminary explanation of the phenomenon of the ＂de qi＂ sensation and the mechanism of acupuncture signal transmission along acupuncture meridians.

中国的养老服务和医疗服务自成体系,如何为老年人提供综合有效的养老照护和医疗服务,成为当前社会面临的重大挑战之一。针对此困境,必须探索社区医养服务供给的协同机制来真正推进医疗机构与养老机构的协同。本文基于医养协同所涉及的目标和利益两个核心变量,构建社区医养服务协同框架,提出目标不同利益分离、目标不同利益契合、目标一致利益契合、目标一致利益分离4种协同关系类型以及分别对应的4种协同形式:治理层级协同、交易式协同、竞争式协同、合作式协同。认为可以依托智慧社区医养服务平台实现医养协同服务,为老年人提供全方位、一站式医养服务。

MoS_(2) nanomaterial with the micro-pompon structure was synthesized by a surfactant-assisted hydrothermal *** morphologies and structures of as-prepared MoS_(2) micro-pompon were investigated by adding different types of surfactants such as cetyltrimethyl ammonium bromide(CTAB),sodium dodecylbenzene sulphonate(SDBS),and polyvinyl pyrrolidone(PVP).The results indicated that the morphology of MoS_(2) could be controlled and changed effectively by the cationic sur-factant of CTAB.A reasonable growth mechanism for hollow structured MoS_(2) micro-pompon by hydrothermal processes was ***,photocatalytic degradation properties of MoS_(2) micro-pompon under visible light were evaluated by degradation of common organic dyes,which include rhodamine B(RhB),congo red,methyl orange,and methylene *** results indicated that MoS_(2) micro-pompon owned the highly selective catalytic ability to RhB with degradation efficiency of 95%in 60 min and 68%in 30 *** the additive of the surfactant,the MoS_(2)-CTAB sample exhibited an enhanced ability of photocatalytic activity where degradation efficiency was improved to 92%in 30 *** method employed in this work could be expanded to fabricate other sulfides with the controllable morphology and structure to further regulate the photocatalytic performance.
