查询词典 ER

Exogenous E2 alone has no effect on cell viability and apoptosis of H9C2 cells, but it can decrease the sensitivity of H9C2 cells to H_2O_2,hence,protect cells against apoptosis caused by oxidative stress.2Exogenous E_2 has downregulation effect on TβRⅠand TβRⅡof H9c2 cells,blocking ER may delete this effect of estradiol.H9c2 cells express ERβonly,suggests that E_2 may exert modulating effect on TGF-βpathway through ERβ.

外源性E2本身并不能影响H9c2细胞凋亡，但能够降低H9c2细胞对H_2O_2的敏感性，保护细胞抵抗氧化应激引起的凋亡。2外源性E2对H9c2细胞的TβRⅠ以及TβRⅡ具有下调作用，阻断ER可消除E2对TβRⅠ和TβRⅡ的下调作用；E2可进一步通过TGF-β通路降低受体后磷酸化smad2/3的水平；H9c2细胞仅表达ERβ，提示E2可能是通过ERβ发挥其对TGF-β通路的调控作用。

At Er~(3+) doping concentration range 0.1-1.5 mol%, Er~(3+) first arrived at ~4F_(7/2) energy level by excited state absorption, then rapidly relaxed to ~2H_(11/2) and ~4S_(3/2) energy levels, the population of which increased, the remarkable upconversion green emission was obtained when Er~(3+) directly went back to ground state by radiative transition.

Er~(3+)浓度在0.1-1.5 mol％时，Er~(3+)通过激发态吸收跃迁到~4F_(7／2)能级，后迅速无辐射弛豫到~2H_(11／2)、~4S_(3／2)能级，~2H_(11／2)和~4S_(3／2)能级上Er~(3+)的布居数增多，Er~(3+)直接辐射跃迁回基态，上转换发射以绿光为主。

ERα is the major subtype of estrogen receptor in vaginal tissue of rats. ERα and ERβ expressions are down-regulated in the vaginal tissues after ovariectomy. Our findings show that estradiol valerate can up-regulate the expression of ERα but ERβ.

The positive signal of ER and ER mRNA distributed in parenchymal and non-parenchymal hepatic cells, especially near the hepatic centrolobular and periportal areas. Ovariectomy decreased ER level and ER mRNA expression significantly (P＜0.05). Hepatic ER and ER mRNA concentration were elevated after treatment with estrogen in both ovariectomy and sham ovariectomy fibrotic groups (P＜0.05), and the elevation of ER was correlated with a marked decrease in hepatic damage and fibrosis.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
