It is a fiber with hollow cross-section and made from renewable natural plant .

它是以可再生的天然植物为原料生产的一种具有独特中空截面的纤维。

Just like hungry humans, underfed plants grow more slowly, are more susceptible[3] to disease and pests, and reproduce less often than healthy plants.

与人类营养不良类似，营养不良的植物生长变得迟缓，越来越容易受到疾病和有害物的侵扰，再生的速度远不如健康的植物。

NRR publishes original contributions written by experts and leaders in the fields of neuroanatomy, pathology, physiology, biochemistry, pharmacology, immunology, and auxanology approaches to examine neural regeneration research; it publishes experimental studies dealing with the structure and function of the nervous system, such as cerebral cortex, Hippocampus, pineal, glial cell, spinal cord neurons, peripheral neurons and sensory nerve injury and regeneration research.

NRR非常感兴趣来自神经解剖、病理、生理、生物化学、药理、免疫、发育等多学科、多层面的题材，感兴趣发表以基础实验性研究为主的揭示大脑皮质、海马、松果体、神经胶质细胞、脊髓神经元、周围神经元以及运动、感觉乃至植物神经损伤与再生的研究原著，对有助于认识神经再生正常和异常机制的临床类文章，如罕见病例报告、调查分析等也可纳入范围。

Different plant expression vectors had been respectively transferred into upland cotton cultivars Jinman12, Jinmian7, Xinluzao1 and Jihe321 via Agrobacterium tumfaciens transformation. These vectors carried cryIAc3 gene, which encodes Bacillus thuringiensis δ-endotoxin, under the control of chimeric OM promoter, CaMV 35S promoter, and cotton leaf curl virus RP promoter respectively; snowdrop lectin gene (Galanthus nivals agglutinin, gna) trans-regulated by rolC promoter controlled TGAla factor; and multivalent expression construct of both cryIAc3-cpti fusion gene and gna gene. A large number of transgenic plants and their progenies had been obtained.

为了提高外源基因的表达量，延缓害虫产生耐受性，本文通过将携带有分别在高效复合OM启动子，CaMV35S启动子及棉花曲叶病毒RP启动子控制下的苏云金杆菌杀虫毒蛋白基因cryIAc3；反式调节因子增强韧皮部表达的雪花莲外源凝集素(Galanthus nivals agglutinin，GNA)基因；以及同时含有cryIAc3、豇豆胰蛋白酶抑制剂基因和gna三价抗虫基因的植物表达载体，以根农杆菌介导法分别将这些表达载体导入了陆地棉新陆早1号、晋棉7号、晋棉12号和冀合321等我国西北棉花主要栽培品种，经体细胞胚再生获得了大批转基因再生植株。

With the property of self-renewing, stem cells transplanted into the injured locations can release some neurotrophic factors which can promote the regeneration of neuron and the neuraxon can drill through the boundary between the implant and host tissue to reconstruct the continuity of neuraxon.

干细胞具有自我更新能力，植入受损部位后，其释放的营养因子能促进神经元的再生，且再生轴突能快速穿越移植物与宿主组织的边界，重建轴突的连续性。

In the study 101 local varieties, 83 modern cultivars, 72 new families of wheat were analysed for the days of callusing at 50%, the number of callusing in 4 weeks in callus induction; and rate of Calli of root formation and the rate of calli of shoot formation in differentiation culture.

为了选育商业应用价值好的新品种，作为受体的植物还需要农艺性状好，育种价值高。一个关键问题是，遗传转化技术是建立在植物的细胞和组织通过组织培养过程再生植株的技术体系上。

Now, more and more people and volunteers go to disaster area to help people who are in trouble.

现在，越来越多的人们和志愿者到灾区帮助那些处于灾难的人们。

A traveling show; having sideshows and rides and games of skill etc..

一种游动的表演；具有杂耍和骑车和技能游戏。
