We conclude that KB-R7843 has protective effects on contrast media-induced nephrotoxicity. The protective role of KB-R7943 may be related to its positive effects on renal hemadynamics through inhibiting the increase of ET-1 and TXA2 induced by contrast media in the environment of hypercholesterolemia and its cytoprotective influence on renal cells.

据此推导：（1）KB-R7943对高胆固醇血症环境下造影剂注射所致的肾损害有保护作用；（2）KB-R7943对造影剂肾损害的保护作用可能与其阻止高胆固醇血症环境下造影剂注射所致的肾皮质ET-1、TXA2浓度的上升从而阻止高胆固醇血症环境下注射造影剂所致的肾血流动力学的紊乱有关以及其对肾脏细胞的细胞保护作用有关。

To determine whether F3, similar to other large DNA iruses, encoded proteins that lock or delay apoptosis, mock- and F3-infected FHM cells were osmotically shocked and assayed for DNA fragmentation 3 hours later. NA fragmentation was clearly seen whether or not shocked cells were preiously infected with F3, indicating that infection with F3 did not block apoptosis induced by osmotic shock in FHM cells.

为了证明F3是否象其大DNA病毒一样编码能阻止或延迟凋亡的蛋白，在模拟感染和正常感染的FHM细胞被渗透压休克后3小时检测DNA片段化；结果显示无论是否休克F3感染都能诱导FHM细胞的DNA片段化，渗透压休克并不能阻止细胞凋亡。

Flame retardants may interrupt or change the decomposition process in several ways:(1)they may melt at relatively low temperatures and resolidify in the form of a foam, which serves as a barrier to heat transfer from the flame to the substrate;(2) they may be converted upon heating into acids or bases, which catalyze the decomposition of the substrate at lower temperatures than are required for the formation of volatile combustibles;(3 ) they may decompose orsublime upon heating to release large amounts of nonflammable vapors which exclude oxygen from the flame; or (4) they may react with chemicakl species within the flame to stop the combustion reaction.

阻燃剂可以从几个方面干涉或改变织物的分解过程：（1）阻燃剂在相对较低的温度时会熔化，然后重新固化成泡沫状，这样就形成了一个屏障，阻止了从火焰向织物的热传递。（2）阻燃剂受热时会分解成酸或碱，这些酸或碱在低于可生成挥发性可燃物的温度下可以催化织物的分解。（3）阻燃剂在受热时会分解或升华，同时释放出大量不可燃气体，这就阻止了氧气对火焰的供应。（4）阻燃剂可以与火焰中的化学物质起反应，使燃烧反应终止。

You know i still dream about being a witch like harry potter and live in the wizardly world, to use my powers to save the day, like stopping the world trade center from falling down, or stopping the war on iraq…i know being a witch is impossible, but to make our world a better place is definitely possible.

波特一样是一名魔法师，用我的力量去解救世界，去阻止世界贸易大楼中心倒塌，去阻止伊拉克战争……。然而，我也知道成为一名魔法师是不可能的，但使我们的世界更美好完全的可能的。

Our political system neither could prevent more than five hundred thousand intellectuals from being set as the Rightists, nor could restraint the frenzied arousing of People's Commune Organization and Great Leap Forward. When the Fascistic Great Proletarian Cultural Revolution abolished constitution and interrupted the parliament activity, there was no any resistance with our political system.

我们的制度不能阻止把五十多万知识分子打成右派，不能阻止公社化和大跃进的疯狂发动，当法西斯式的文化大革命废止宪法、停止议会活动的时候，我们的制度没有任何反抗。

This innocent old superstition dictated that all loaves of bread must be marked with a sign of the cross before baking. The idea was that the cross would prevent the devil from sitting on the loaf - and thereby prevent him from cursing or spoiling the bread.

古时候的迷信有这样一个说法，所有的面包在进行烘焙之前都要在上边划上一个十字，据说这样的一个十字可以阻止恶魔坐在面包上面，进而就可以阻止他对面包下诅咒，或者是毁坏面包。

according to the mechanism of bitter formation, the bitter taste masking technology is classified into different sorts from different taches that disturb the bitterness formation, include adding the taste correcting substance to confuse the cerebral taste; staving or preventing the drug releasing in mouth and segregating the contact between drug and taste buds; anesthetizing the taste cell to enhance the threshold of bitter taking; preventing bitter taste receptor combining with bitter blocker, cutting off the signal transduction pathways etc.summerize the methods of taste masking technology,besides,describe the method's advantages and disadvantages, and the technology of preparation.provide academic direction for the reasonable use of bitterness taste masking.

依据苦味形成机理，从干扰苦味形成的不同环节将中药苦味掩味技术分为添加矫味剂，混淆大脑味觉掩盖药物苦味；延缓或阻止药物在口腔释放，隔离药物和味蕾的接触；麻痹味觉细胞，提高苦味感受阈值；阻止苦味受体与苦味剂的结合，切断信号传导掩盖苦味等4类，综述掩盖中药苦味的方法，并简述各方法的优缺点和制备技术，为合理应用苦味掩味技术提供理论指导。
