But theimprovement was still needed because of its late maturity and low grain-weight. The NChybrid is crossing with other vulgare so as to breed new NC hybrid suitable forproduction.

但在千粒重和早熟性上还有欠缺，目前正用其它普通小麦品种进行转育，以期培育出生产上能用的核质杂种小麦。

AIM: To investigate the expression of human β-defensin-2 (hBD-2) mRNA and the changes of NF-κB activity induced by lipopolysaccharide in human primary epitheliums. METHODS: The pulmonary primary epitheliums from human were stimulated with LPS and the expression of hBD-2 mRNA was detected by reverse transcription polymerase chain reaction.

目的：观察脂多糖诱导人气道上皮细胞人β防御素－2(hBD-2)的表达及核转录因子κB活性的变化，探讨NF-κB在LPS诱导人气道上皮细胞hBD-2表达中的作用。

It is found that before the pearlitic and upper-bainitic reactions, a pro-cutectoid orpro-bainitic phase is precipitated along the austenite grain boundaries in the cyanidedsamples; and it is thought that this is likely a nitrogen-bearing phase which provides thephase boundary effect for the nucleation of the reactions and impoverishes the parentaustenite in alloy content, thus accelerating the transformation of austenite.

实验中发现，在珠光体及上贝茵体形成之前，氰化试样中均有一种过剩相沿奥氏体晶粒边界析出。这种先析相可能是一种含氮的化合物，其析出为珠光体及上贝茵体的非自发形核提供了现成的有利界面，并使奥氏体合金化程度降低，因而加速了转变。

Taken together, compared with the susceptible strain, the resistance strai ns have no obvious changes in karyotype but have distinct difference in DNA level, which suggests that insecticide resistance is related to the changes hi gen omic DNA in diamondback moth.

从上面的结果看来，与敏感品系相比，三种抗性品系小菜蛾的核型没有发生明显的变化，但在DNA水平上存在明显的差异，说明小菜蛾的抗药性与基因组DNA的变化有关。

When applied the spiny eel X chromosome library probes to the chromosomes of the two fish, different signals were distributed: in Siniperca chuatsi, besides some little signals on lot of autosomes, a large bright signal region was detected on the 8th chromosomes, which represented a synteny of spiny eel X chromosomes; but in Channa argus, no distinct synteny was found.

当以刺鳅的生物素标记X文库探针对鳜鱼和乌鳢的有丝分裂染色体进行染色体涂绘后，经过核型分析和统计分析表明，在这两种鱼的染色体上的杂交信号分布是不同的：在乌鳢中，除散在信号外，在其第八号染色体近着丝粒部位存在着一段较大的信号结合区域，应是与刺鳅的X染色体同源的保守同线群，而在鳜鱼中，只有散在信号分布于多条染色体上，没有明显的保守同线群存在。

Global cataclysms are 18 events that affected all of earth and were Nuclear in nature, with large atomic bombs detonated often causing a nuclear winter of all of Earth.

全球大变动是指影响地球上所有一切并有核事故性质的18件大事，大型原子弹爆炸通常导致地球上的一切都进入核子冬天。

The results were as follows:The protein,wet gluten content and sedimentation of all hybrid seeds with 4 alien cytoplasms were superior to those with T.aestivum cytoplasm.The differences of wet gluten content and sedimentation of hybrid seeds with Ae.kotschyi and Ae.variabilis cytoplasms,at 5 percent significant difference,were especially obvious.

结果表明，由它们所配制的杂种小麦在蛋白质含量、湿面筋含量、沉淀值等性状上均高于具有普通小麦细胞质的相同核型杂种小麦，尤其粘、易型某些组合在湿面筋含量、沉淀值两性状上差异达到显著水平。

At the same time, comprehensive assessment and classification of varieties were done. The result showed that 8 characters were loaded on 5 main factors. The first were intergrated factor of fruit, including single fruit weight, pulp thickness, edible rate and contents of soluble solid state material, From the second to the fifth factors, it reflected the fruit texture, mature period, fruit pit weight and flavor, respectively. The accumulation variance of five main factors contributing to the 8 characters reached to 93.329%, which basically summarized all 8 characters main information.

在相关分析基础上进行因子分析，结果表明，8个性状分别载荷在5个主因子上，第一主因子为果实综合因子，包括单果重、果肉厚度、可食率和可溶性固形物含量；第二至五主因子分别为反映果实质地、成熟期、果核重、风味的因子，这5个主因子对8个性状的累计方差贡献率达到93.329%，基本概括了全体8个性状的主要信息。

Thus, there may be some correlation between those substances and development of gonads of Styela plicata.

而在神经腺上，ER-α和ER-β免疫阳性物质定位在上皮细胞的胞核。

By incorporation of tritiated thymidine or 5-bromodeoxyuridine and using them as the markers, we found that the basal cells, Clara cells and type II alveolar epithelial cells in the pulmonary tissues may in some way behave like stem cells and can eventually differentiate into respiratory tract epithelium.

通过应用cells in induced group cultured for 2 weeks 标记的胸腺嘧啶(3H-TdR)或5-溴脱氧尿核苷的渗入进行标记，发现肺组织的基底细胞、Clara 细胞和肺泡II型上皮细胞可能具有干细胞特征，能最终分化形成气道上皮。
