诱导因素

A modified Galanthus nivalis agglutinin gene was introduced into the genome of main cultivar 'Ningqi No.1' of Lycium bararum in vitro with explants of leaf disks mediated by Agrobacterium tumefaciens. Several factors affecting transformation efficiencies were studied based on induction rate of resistant callus. An effective system for genetic transformation of Lycium bararum was set up, and 70 kanamycinresistant transformants were obtained.

为了解决枸杞蚜虫侵害的难题，以宁夏枸杞主栽品种&宁杞1号&叶片为外植体，通过农杆菌介导的转化方法，将改造后的雪花莲凝集素GNA基因转入枸杞，以抗性愈伤组织诱导率作为转化效率的指标，对影响转化效率的因素进行了研究，初步建立了转化频率较高的转化系统。

Therefore, we studied the incidence and possible risk factors for hemodynamic deterioration during GA induction.

因此，我们研究在全麻诱导期间血流动力学恶化的发生率和可能的危险因素。

MAIN OUTCOME MEASURES : Iris heterochromia identification at the 6-month evaluation of the photographs.

因此，年龄可能是拉坦前列素诱导的虹膜色素改变的一个非常重要的危险因素。

Insulin-like growth factor is a significant factor to induce muscle hypermyotrophy.

胰岛素样生长因子Ⅰ是诱导骨骼肌肥大的重要因素。

Recent studies found that ischemic brain damage is resulted from many reasons such as functional rearrangement of glia cells, an ion balance disorder, lipide peroxidation induced by free radicals, and changes of neurotransmitters.

许多继发性因素，如缺血后神经胶质细胞功能的重新安排，离子平衡紊乱，自由基引起的脂质过氧化损伤，以及神经递质的改变等可诱导神经细胞死亡，继而导致脑损伤，但有关缺血性细胞死亡机制目前还无定论。

In the favorable inoculation season, the induction percentages of meristematic globules from flowers and embryogenic calli from scalps were 15～80％ and 0～10％ respectively, depending on the cultivars and incubation conditions.

从多芽体获得胚性愈伤组织的概率大约为0～10％，胚性愈伤组织的诱导率受基因型和品种、接种时期及培养条件等因素的影响。

Oil film thickness along the piston skirt in motored engine was measured, and the comparison with theory result was given.

最后在实验研究中，本文国内首次在活塞裙部油膜厚度中采用了激光荧光诱导的测试方法，主要工作是：分析了激光荧光诱导法的基本原理，建立了测膜厚的基本定量关系模型，通过实验分析了膜厚测试的各种影响因素，通过实验对不同香豆素荧光光谱和激发光谱特性进行了分析，通过实验确定了选取香豆素的种类和溶液浓度的基本原则，自主开发了以光纤为光学光路的测试系统并对系统进行了标定，对内燃机冷拖动状态的活塞裙部进行了实测，并与理论测试结果进行了对比。

Objective: To explore the influence of serum of different concentrations towards co-cultured neuroepithelial stem cells and Schwann cells, and further to seek the factors inducing the orientation differentiation of neural stem cells.

目的：探讨血清对联合培养神经上皮干细胞与Schwann细胞的影响，进一步寻求诱导神经上皮干细胞定向分化的影响因素。

Apoptosis induced by sTRAIL is one of the factors of neuronal damage after cerebral infarction.

sTRAIL诱导的细胞凋亡是脑梗死后神经元损伤的因素之一。

In conclusion, these results suggested that (1) the ageing-associated decline in fertility of female KM mouse was due to a decrease in both quantity and quality of oocytes;(2) the ooplasm from young mice did not correct the meiotic errors of aged mice, and the ooplasm from aged mice did not induce abnormal segregation of meiotic chromosome of young mice, indicating that meiotic anomalies found in the oocytes of aged mice might be related to nucleus or chromosomes and relevant factors;(3) a critical nucleocytoplasmic ratio was essential for normal maturation and segregation of meiotic chromosomes of oocytes and development to 2-cell embryos.

本研究结果表明：（1）昆明白小鼠与衰老相关的生育力下降是其卵母细胞数量减少和质量下降的综合结果；（2）年轻小鼠卵母细胞细胞质不能纠正老龄小鼠GV的减数分裂错误，老龄小鼠卵母细胞细胞质也不诱导年轻小鼠的GV发生减数分裂错误，老龄小鼠卵母细胞减数分裂异常很可能与细胞核或染色体及其相关因素有关；（3）关键的核质比对卵母细胞正常的成熟、减数分裂染色体分离及2-细胞期胚的发育是绝对必需的。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
