查询词典 elementary cell

Companion cell An elongated thinwalled cell cut off longitudinally from the same meristematic cell as the SIEVE ELEMENT with which it is closely associated.

The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

The cell to cell contact could facilitate the transformation. It was found that the B. subtilis strain, cultured not only in MM medium, but also in LB medium, could be transformed by cell released or chemically extracted DNA by the method of agar plate transformation, although the LB medium was previously believed not to support this process in traditional transformation protocol.

结果表明，该菌在这两种培养基中培养时均可在对数生长期向培养液中主动分泌有生物活性的DNA，且细胞间接触有利於转化过程的进行，暗示在本实验条件下DNA供体细胞可能具有某种主动功能。

The invention can further improve the photoelectric conversion efficiency of the solar cell, makes full use of the functions of the upconversion material to convert up the wide infrared spectrums into the visible light and combine the thin film solar cell and the material with the upconversion function, so as to form a novel high efficient solar cell.

本发明能够进一步提高太阳电池的光电转换效率。充分利用上转换材料的功能，将宽谱域红外上转换为可见光，将薄膜太阳电池与该具有上转换功能的材料相结合，形成一种新型高效太阳电池。

The study on development and differentiation of cells in bamboo culm is very limited,especially on formation and development of cell wall.Cell wall is the main substance of bamboo cell structure.

与木材相比，竹材细胞壁的研究工作仍处于起步阶段，对竹茎杆细胞的发育过程，尤其是细胞壁形成和分化过程的研究远远不够。

Cell Delineation is responsible for defining the cell boundaries at the originating endpoint (e.g., ATM cell switch or ATM workstation) in order that the receiving endpoint can reassemble (i.e., identify and recover) all cells associated with a data payload that has been segmented (i.e., cut up into ATM cells).

信元定界负责定义始发端（例如 ATM 小区交换机或 ATM 工作站）的小区边界，这样接收端可以将那些与已经分段的（也就是切割成数个 ATM 小区）数据有效载荷相关的所有小区重新聚集。

METHOD: The extract of sago cycas leaves was added to K562 and HL-60 cell culture fluid respectively, Cell clusters, live-cells,dead cells were calculated and cell protein was detected. The results were compared with P. B. S. control group.

Because different cell lines may show various levels of susceptibility to adenovirus infection and virus production, non-selectively replicating wtAd5 was used to be a comparison with the tested conditionally replicating adenovirus CNHK500.ONYX-015, the first replication-competent adenovirus entered into clinical trials was also used to be a comparison. We used virus proliferation assay, cell viability assay and western blot to evaluate the proliferation and cytolysis selectivity of CNHK500. Results demonstrated that the CNHK500 virus proliferation multiples in breast cancer cell lines after 48 hours is similar to that of wtAd5, ONYX-015 virus proliferation ability is less than that of CNHK500 in cancer cells.

然后，通过与ONYX-015（E1B 55 KD a蛋白缺失的2型和5型嵌和型腺病毒，美国ONYX生化制药公司研制）、wtAd5进行对比，利用病毒增殖实验和细胞生长抑制实验，验证了CNHK500选择性增殖能力和肿瘤特异性杀伤作用；利用Western Blot检测CNHK500腺病毒E1A和E1B在乳腺癌细胞和正常成纤维细胞中的表达差异，揭示了腺病毒肿瘤靶向性的机制；利用携带绿色荧光蛋白的CNHK500-EGFP感染乳腺癌细胞株和正常成纤维细胞株，直观地观察其感染乳腺癌细胞的能力和在乳腺癌细胞中的增殖过程。
