查询词典 nuclear

Produce the basic conditions for thermonuclear reaction, first nuclear fuel must be heated to a temperature high enough (several tens of millions of degrees), this time the nuclear fuel has been ionized into a mixture of electrons and ions, namely plasma; Second, we must binding them together so that they have conducted nuclear reaction time.

After the identification of SARs in Attacus ricini rRNA gene, its rRNA gene and NTS were also found to have the ability binding with the nuclear scaffold of Saccharomyces cerevisiae. The 1kb NTS fragment which can bind clearly with nuclear scaffold of Attacus ricini was the chief fragment binding with yeast nuclear scaffold. This indicated the homology between this two kinds of SARs and provided an evidence for the evolutionary conservation of SARs.

在鉴定蓖麻蚕rRNA基因中具有骨架结合区域之后，利用体外结合的方法发现，蓖麻蚕rRNA基因及其非转录间隔区片段也具有与酵母核骨架结合的能力，尤其是能与蓖麻蚕核骨架结合的非转录间隔区1kb片段，也能明显地结合于酵母核骨架，这一结果表明二者的SAR顺序具有一定的同源性，为骨架结合区域具有进化保守性提供了又一证据。

Methods Nuclear β-catenin expression was detected by immunohistochemistry in 77 lesions with desmoid-type fibromatosis and 171 other spindle cell lesions, including superficial fibrmoatosis (n=18), nodular fasciitis (n=36), keloid (n=16), scar (n=10), granulation tissue (n=9), synovial sarcoma (n=38), neufibroma (n=13), solitary fibrous tumor (n=12), gastrointestinal stromal tumor (n=10), low-grade myxofibrosarcoma (n=3), low-grade fibromyxoid sarcoma (n=3), and smooth muscle tumor (n=10). In addition, the immunohistochemical expressions of ER-α, ER-β and Ki-67 were examined in all of the lesions with desmoid-type fibromatosis. The nuclear immunohistochemical staining for nuclear βcatenin and ER-β was graded as high level (≥25% of cells), low level (5%-25%) or none.

3Rhe distribution and change of proliferating cell nuclear antigen in seminiferous tubule: The positive staining of proliferating cell nuclear antigen was found in slices of all groups, the immunological positive products were located at karyon, usually in brown yellow granules, only a small part of them in diffuse state; the immunological positive cells were mainly the spermospores, besides a small quantity were spermiocyte, supporting the cell and myoid cell nuclear to be stained.

3增殖细胞核抗原在生精小管中的分布及变化：各组切片均可见增殖细胞核抗原阳性染色，免疫阳性产物位于细胞核，通常呈棕黄色颗粒，小部分呈弥散状；免疫阳性细胞主要是精原细胞，另外还有少量初级精母细胞、支持细胞和肌样细胞核着色。

The outer neuroblastic layer before it divided to inner and outer nuclear layer and outer complexiform layer and gonglion cell layer showed a temporal PCNA positive which was related to proliferation. The three cell layers had another PCNA positive when finished time changed from outer to inner after their morphologic development basically completed( outer nuclear layer:11～15 days,inner nuclear layer: 8～16 days, gonglion cell layer:16～21 days).

PCNA显示在外成神经细胞层分化为内、外核层和外丛状层之前，和节细胞各有一次和增殖相关的阳性表达。3个细胞层在形态学的分化基本完成后，又出现了一次结束时间是由外向内变化的阳性过程（外核层：第11天至15天：内核层：第8天至16天，神经节细胞层： 16天到21天，这一次阳性表达过程可见到细胞形态向成年形态的转化。

After NMDA stimulation, he concentrations of Ca~2+ and NO in both nuclear and plasma rise observably, especially in the netlike structures; the change of Ca~2+ concentration in nuclear is larger than that in plasma,however the changes of NO concentration in nuclear and plasma are similar. We also observed comparative increases of the concentration of Ca2+ and NO in neurodendrite after NMDA stimulation.

NMDA刺激后神经元细胞核和细胞质内Ca~(2+)和NO都明显升高，尤其在细胞核和细胞质内的网状结构处；细胞核内Ca~(2+)升高幅度大于细胞质，而细胞核内NO的升高幅度却与细胞质相近；另外，树突内的Ca~(2+)和NO升高也较明显。
