查询词典 mitosis

It indicated that the yield of tetraploidy not more than 25% induced by inhibiting the first mitosis with CB, colchicine and 6-DMAP, respectively, while it can be induced with higher percentage by blocking PB1releasing with CB. The tetraploidy percentage of groups shock began at 15—22min after fertilization are higher than that shock began at 42min, and the yield of tetraploidy also increased with the CB density and time lasting.

结果表明，CB、6-DMAP和秋水仙素抑制扇贝第一次卵裂诱发四倍体的比例低于25%；采用CB抑制PB1可有效地诱导产生四倍体，从授精后42min提前到15—22min开始处理，抑制PB1的放出有助于提高四倍体的比例，在12℃，处理开始和终止时间分别在授精后20—22min和62—67min时(即PB2始出现时)，面盘幼虫四倍体率最高，为56.5%。

Tetraploid veliger were carried out with four chemicals on this scallop in 1998—2000. Tetraploid were induced by inhibition of the polar body and first mitosis with cytochalasin B, colchicine, 6-DMAP and caffeine combined with CB, respectively.

中文摘要：1998—2000年采用细胞松弛素B、秋水仙素、6-二甲基氨基嘌呤(6-DMAP)以及咖啡因等药物抑制虾夷扇贝第一极体(PB1)释放、PB1和第二极体(PB2)释放以及抑制第一次卵裂等方法，诱导虾夷扇贝四倍体。

During the studies, the principle of mitosis coefficients decrease was initially detected between WAF's loading rate of ordinary lubricants and its relative luminosity.

研究中首次发现，一般润滑油WAF溶液载荷率与其相对发光度呈指数递减关系的规律。

Objective: To research the expression of phosphodiesterase 3A (PDE3A) in zygote of mouse during the first mitosis.

目的：研究磷酸二酯酶3A(PDE3A)在小鼠受精卵第1次有丝分裂中的表达。

The single micronucleus and multi-micronucleus were observed at the interphase. The chromosome aberrational cells including chromosome fragment, lagging chromosome, chromosome bridge and circular chromosome were found during the mitosis. RAPD analysis of seedling genomic DNA variation in M 2 generation of three mutants showed their DNA sequences had changed. The result confirmed that the implantation of 7Li +3 ions could induce genetic mutation in wheat.

对幼苗根尖细胞学研究观察，获得单桥、双桥、桥断裂、落后染色体、三级、断片和微核等畸变类型；对已获得的小麦突变株，分别进行M2 代DNA分子的RAPD分析，结果发现DNA均发生变异，证明7Li+ 3 注入通过内靶核反应能够诱发小麦在分子水平上产生遗传变异。

On light microscopy,there was abundant cosinophilic cytoplasm,with the tumor cells being aciniform or tubiform without significant atupia and mitosis.

光镜下瘤细胞排列成腺泡状或管状，细胞质含丰富的嗜酸性细颗粒，细胞无明显异形性和核分裂象。

Studies also indicated that genistein exsists not only in soybeans but also in many kinds of plants such as vegetables and fruits.As a potential anticancer agent, the actional mechanisms of genistein mainly includes as follows:First, genistein can depress the activity of protein tyrosine kinase and transduction pathways for the phosphorylation of receptors and mitosis signal. So genistein can lead to cells' proliferation depressed. Second, genistein has minimal effects of phytoestrogens. It can be combined with estrogen receptor and improve the synthesis of cellular sex hormone binding glulobin, and improve the activity of UDP-glucuronyl transferase. Through these pathways, it can inhibit the cell activity of breast cancer and prostate cancer.

作为一个很有潜力的抗肿瘤物质，三羟异黄酮的作用机制主要包括：①抑制蛋白酪氨酸激酶活性，可阻抑PTK引起的受体磷酸化和有丝分裂的信号传递，导致癌细胞增殖受抑；②弱雌激素作用：可通过与体内雌激素受体结合，并可增加细胞内性激素结合球蛋白的合成，增加UDP-葡糖醛酸转移酶的活性等途径抑制乳腺癌和前列腺癌细胞活性；③拓扑酶Ⅰ和Ⅱ抑制剂，抑制细胞活性；④上调细胞周期性负性调节因子P21WAF1/CIP1的表达，使之负性调节因子作用增强；⑤可阻止胰岛素样生长因子-Ⅰ、肝细胞生长因子和神经生长因子的作用而抑制肿瘤生长；⑥其他：抗氧化作用、抑制热休克蛋白、诱导细胞凋亡、抑制新生血管生成和抑制多种耐药相关蛋白等。
