死鏈結 的英文怎麼說
中文拼音 [sǐliànjiē]
死鏈結
英文
dead link-
Conclusions the intrapleural administration of streptokinase does not improve mortality, the rate of surgery, or the length of the hospital stay among patients with pleural infection
結論在胸膜感染的病人中，鏈激酶胸膜腔內給藥不能改善死亡率、手術率或住院時間的長短。It is toxic for most mammalian cells since ricin a chain ( rta ) is an rna specific n - glycosidase that removes a specific adenine residue in a highly conservative region from among over 4000 nucloside residues present in 28s rrna, and causes protein synthesis inhibition and cell death
Rta具有n -糖苷酶活性，可催化28srrna在4234位脫去腺嘌呤，使核糖體60s亞基失活，從而抑制蛋白質合成，導致細胞死亡。 b鏈（ rtb ）是結合鏈，能和細胞表面半乳糖受體結合，協助a鏈進入細胞內。Alterations in glycosylation have been proposed to participate in cell adhesion, receptor activation, cell differentiation and tissue morphogenesis. because the early embryo is composed of cells that must adhere to other embryonic cells, it seems likely that glycans modulating this adhesion would have been indispensable for early development. genetic elimination or partial abrogation of expression of some major classes of glycans, such as n - glycans, glycosphingolipids, hyaluronan and sialic acids, has been shown to be lethal during murine embryogenesis
胚胎發育過程中伴隨著細胞表面糖鏈表達水平及結構的改變，研究表明這些改變參與介導了胚胎細胞之間的粘附聯系，因此，糖鏈對于胚胎正常發育是必須的，一些糖鏈結構（如n -連接糖鏈，糖鞘脂，透明質酸，唾液酸等）的表達缺失能導致小鼠死亡于胚胎的早期發育階段。Three kinds of the usual methods of rotor flux estimation are compared and analyzed, and the method of rotor flux estimation based on the voltage model is studied in detail. and the output phase voltage is reconstructed by means of the dc - bus voltage and the switching states of the inverter, the effect of the dead time and saturating voltage - drop of the switches on flux estimation is discussed. and the method of synchronizing instant speed identification is also studied deeply
