The MADS-box(DAM)gene PpDAM6,which is related to dormancy,plays a key role in bud endodormancy release,and the expression of PpDAM6 decreases during endodormancy ***,the interaction network that governs its regulation of the endodormancy release of flower buds in peach remains *** this study,we used yeast two-hybrid(Y2H)assays to identify a mitogen-activated protein kinase,PpMAPK6,that interacts with PpDAM6 in a peach dormancy-associated SSHcDNA ***6 is primarily located in the nucleus,and Y2H and bimolecular fluorescence complementation(BiFC)assays verified that PpMAPK6 interacts with PpDAM6 by binding to the MADS-box domain of *** real-time PCR(qRT-PCR)analysis showed that the expression of PpMAPK6 was opposite that of PpDAM6 in the endodormancy release of three cultivars with different chilling requirements(Prunus persica‘Chunjie’,Prunus persica ***‘Zhongyou 5’,Prunus persica‘Qingzhou peach’).In addition,abscisic acid(ABA)inhibited the expression of PpMAPK6 and promoted the expression of PpDAM6 in flower *** results indicated that PpMAPK6 might phosphorylate PpDAM6 to accelerate its degradation by interacting with *** expression of PpMAPK6 increased with decreasing ABA content during endodormancy release in peach flower buds,which in turn decreased the expression of PpDAM6 and promoted endodormancy release.

朱砂作为颜料或墓底铺垫在黄河流域和长江流域的众多先秦考古遗址中都有发现,然而现代朱砂矿藏则主要集中分布在我国的西南地区。因此,先秦时代很可能存在某种形式的广域交换网络,促成了朱砂和其他物品的远距离传播。经过对国内外朱砂产地相关研究方法的评述,可知采用硫同位素和汞同位素相结合的方法对古人可能利用的汞矿的朱砂样本和考古遗址出土的朱砂样本进行采样分析,有望重建先秦朱砂交换网络。

The global spin alignment of vector mesons has been observed by the STAR collaboration at the Relativistic Heavy Ion Collider （RHIC） at Brookhaven National Laboratory （BNL）.It provides a unique opportunity to probe the correlation between the polarized quark and antiquark in the strongly coupled quark-gluon plasma （sQGP） produced in relativistic heavy ion collisions,opening a new window to explore the properties of s *** addition,spin alignments of vector mesons have also been observed in other high-energy particle collisions such as e+e-annihilations at high energies where hadron production is dominated by quark fragmentation *** results obtained are quite different from those obtained in heavy ion collisions where quark coalescence/combination mechanism dominates suggesting strong dependence on hadronization *** comprehensive studies in different hadronization processes are *** this article,we present a brief review of theoretical and experimental advances in the study of vector meson’s spin alignments in a variety of high-energy particle collisions,with emphasis on hadronization mechanisms.

五更泻是以晨起即泻、泻下急迫、泻后则舒,伴或不伴腹痛的泄泻。许多书籍认为五更泻即肾泄,实则不然,肾泄仅为五更泻的一种,尚有其他证型如肝经郁热型有待进一步认识。五更为黎明之际,阴消阳长,人与天地相参,一身阳气处于升发之时。肝主左升,肺主右降,一身之气的升降全耐肝肺。情志不畅、感受外邪等因素引起肝失疏泄,致肝气上升不及,流注于肺的经气减少,肺经失于充盛,肝气旺盛化热。肝旺侮肺,肺气不降,水道通调失职,水液运行不循常道,不入膀胱偏走大肠,与糟粕同下则发为泄泻。其病机为肝旺侮肺、热移大肠,治疗给予疏肝清热、因势利导之法可收良效。
