查询词典 nucleus

From traditionary nucleus pulposus exsection to spinal fusion,endoscope and minimally invasive techniques,and prosthetic disc nucleus and artificial disc replacement in recent years, however,they relieved clinical complaint temporary by means of the destruction of structure and function of lumbar intervertebral disc.

从传统的髓核摘除术到脊柱融合术、内窥镜和微创技术及近年开展的人工髓核和椎间盘置换术，但它们都是以破坏椎间盘结构和牺牲生物力学功能为代价的，不能阻止和逆转椎间盘退变，因此椎间盘退变的基因治疗和组织工程成为研究的热门课题。

Poptosis-inducing factor is a mitochondrion-localized flavoprotein with NADH oxidoreductase activity, which is encoded by the nuclear gene. Following induction of apoptosis, AIF is released from mitochondria and translocated to cytosol, and then to the nucleus. The mechanism of AIF translocation from mitochondria to nucleus is still unclear. It has been suggested that translocation is due to the presence of nuclear localization signal.

bstract： AIF(apoptosis-inducing factor)为位在粒线体内膜膜上之蛋白质，在正常细胞中，能够藉由维持电子传递链复合体I的稳定性，进而影响细胞能量的产生及自由基的清除，并且也会维持粒线体的构造；反之，当细胞遭受到不当刺激时，粒线体膜通透性改变，使得原本存在於粒腺体间质中之AIF，被释放出来，进入细胞核内造成DNA片段化，进一步促进细胞凋亡。

质量保证作为核设备制造管理的核心和主要内容，已成为制约核电设备制造国产化的关键因素之一。本文以东方锅炉股份有限公司在广东岭澳核电站2×1000MW压水堆核岛主设备分包制造中的核质保实践为例，阐述了核设备制造质量保证大纲的建立原则和主要运行方式，以供从事我国核设备制造行业质量保证工作的有关人员参考。

In resting cysts, the microtubules under the pellicle, cortical ciliatures, conjunctions between cilia basal bodies, supporting structure of basal bodies and other microtubule structures are absorbed in different extent; microtubule-like assemble bodies appear at the center of the remained cilia basal bodies; the granules of chromatin and nucleolus in macronucleus become smaller whereas nucleus pores of the micronucleus become bigger; the inner membrane of some nucleus pores are attached with chromatin.

结果表明：纤毛虫形成包囊过程中，皮层细胞质中产生具有自噬泡消化特征的细胞器，将部分纤毛结构等逐步消化；休眠包囊中，表膜下微管、皮层纤毛器和纤毛基体间连接、基体托架及其他微管结构不同程度地被吸收、在残剩纤毛基体的中央形成微管形结构聚合体，大核染色质和核仁颗粒变小，核孔增大，并发生染色质附着于核孔内膜的现象；细胞脱包囊期间，皮层细胞骨架、线粒体等经历了在残剩结构基础上的再分化。

Bnormal MRI manifestations in all of the 20 cases with acquired hepatocerebral degeneration,in which T1WI demonstrated increased signal in hibateral lentiform nucleus (n=20),globus pallidus(n=17),surrounding mesencephalon red nucleus(n=15),and in anterior pituitary(n=4)While T2WI demonstrated no corresponding alteration in signal intensityConclusion Abnormal MR signal in the patients with acquired hepatocerebral degeneration has special features and MRI has right value for the diagnosis of this disease
