阻断

Each had the followings measured: the antegrade Wenckebach point and 2:1 conduction point and the effective refractory period. Adenosine triphosphate was given intravenously at the time of atrium pacing until the dose of ATP reaches 0.30 mg/kg or the antegrade conduction of the AVN was blocked.

选择19例预激综合征行射频消融术后且房室结前传文氏点等于或大于150次/分的患者，测量房室结前传功能（前传文氏点、2：1点）和有效不应期，在心房起搏时静脉推注ATP，直至0.30 mg/kg或出现房室前传阻断。

Western Blot showed that a Mr 62×103 ALK 1 protein could be expressed after transfecting pcDNA3.1/ALK 1 into HEK293 cells. CONCLUSION: Human full length ALK 1 cDNA is successfully cloned and can be expressed in transfected HEK293 cells, which provides a solid basis for exploring the effects of ALK 1 mediated TGFβ signal pathway in wound healing and the development of keloid.

为了深入研究ALK 1介导的TGFβ信号转导通路在创面愈合过程所发挥的作用，并探索阻断该通路是否可抑制瘢痕疙瘩的发生，发展，我们克隆了人ALK 1基因并制备了真核表达载体，为进一步的工作奠定了基础。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
