The anion has as follows 8 big benefit: Sterilize surpass the oxygen negative ion free radical but kill various pneogaster infectious disease bacterium; Dust removal makes air middle dust heavy getting together, suspension pellet the brute force is collected; Deodorization dislodges various the peculiar smell living , bad smell , improves a bag; Eliminate cigarette smoke fog , dust in wiping out air rapidly , completely eradicate the second-hand cigarette; The various deleterious chemistry volatilizes a gas , wipes out "the invisible killer " in getting rid of poison dislodging air; Work efficiency, removes health care rise becoming fagged , improve the heart-lung function, strengthen the human body immunocompetence; Improve the looks making an epithelium bring negative charge along , make germs lose the go at ability to the cell , keep skin glossy; Except that static electricity is positive static electricity in general in life, will be physically and mentally healthy to the human body bringing about hidden trouble, the anion has an effect to neutralize this static electricity.

负离子有如下8大好处：杀菌——超氧阴离子自由基可杀灭各种呼吸道传染病菌；除尘——使空气中尘埃聚沉，强力收集悬浮颗粒；除臭——去除各种生活异味、臭味，改善生活环境；消烟——快速消灭空气中的烟雾、尘埃，杜绝二手烟；去毒——去除空气中各种有毒化学挥发气体，消灭&隐形杀手&；保健——提高工效、消除疲劳，改善心肺功能，增强肌体免疫能力；美容——使上皮细胞带负电荷，使病菌失去对细胞的攻击能力，保持皮肤光滑；除静电——生活中一般为正的静电，会对人体身心健康带来隐患，负离子有效中和这种静电。

Methods The total RNA was acquired from young rabbit particular cartilage, the BMP7 gene was inserted into pcDNA-3.1 to construct eukaryotic expression vector plasmid of pcDNA3.1-BMP7; the target gene-BMP7 was identified respectively by PCR analysis, restriction enounces analysis and nucleotide sequencing; the plasmid was transfected into adult rabbit knee articular chondrocytes, then the expression of BMP7 was detected by in situ hybridization, PCR and Western blotting.

从体外培养的幼兔膝关节软骨细胞中提取总RNA；按GenBank BMP7基因序列化学合成2条引物，采用RT-PCR方法得到BMP7基因；将BMP7基因片段插入到真核表达载体pcDNA 3.1中，构建pcDNA3.1-BMP7真核表达载体质粒；利用双酶切、PCR及核苷酸序列分析鉴定BMP7目的基因；将重组pcDNA3.1-BMP7真核表达载体质粒转染家兔关节软骨细胞，分别采用原位杂交、PCR、Western blotting法测定BMP-7表达。

So, this time, before bathing the healthy cells in fats or cytokines, the team added a chemical that blocks the activity of DNMT3B, an enzyme which they found methylates PGC-1 alpha.

所以，这次在把正常细胞放入脂肪和细胞因子之前，研究人员加入了一种能阻碍DNMT3B活动的化学物质，即一种会使PGC-1甲基化的酶。

For example, it secretes larger amounts of cytokines, molecules that carry chemical signals between cells.

比方说，它分泌大量能在细胞间传递化学信号的细胞因子，分子。

The ulnas of fetal mice were cultured for 48 hours in BGJb medium treated respectively with estradiol and purearin. After fixing long bones and decalcification, paraffin sections were made, and then performed immunohistochemical staining for determining the level of typeⅠcollagen protein in growth plates. Positive cell locations in the resting zone, proliferative zone and hypertrophic zone of epiphyseal plate were observed under light microscope.

剥离出胎鼠尺骨，置于BGJb培养基中，葛根素和雌二醇作用48 h后，将长骨固定，脱钙后作石蜡切片，进行免疫组织化学染色，光镜下观察骺板静止区、增殖区和肥大区阳性细胞定位，图像分析系统下测定免疫反应阳性细胞面积。

Semi-thin sectioning and the method c.ommonly referred in histochemistry were used to study the development of vascular bundles in Aloe arborescens leaves with emphasis on the origins and tissue types of vascular bundle sheath cells and aloin-containing cells.

采用半薄切片和组织化学方法研究了木立芦荟叶内维管束的发育过程，并着重于维管束鞘细胞和芦荟素细胞的来源及组织类型。

It contains DNA molecules, which house the cell's chemical information.

细胞核是一个细胞的控制中心，它藏著带有细胞之化学讯息的

Results The physically and chemically treated SIS was pure with more hollows on the surface and undamaged collagen fibers. The cartilage cells could grow, adhere to and differentiate on the layer of SIS and enter into the hollows, secrete a great deal of extracellular matrices.

结果 经物理和化学处理的SIS纯度高、孔隙多，胶原纤维未受损；软骨细胞在SIS材料上生长、黏附、增殖，并能长入材料的孔隙内，分泌大量的细胞外基质成分。

The wild type protein and mutant S103A was shown to exhibit the same folding tendency as that chemically prepared from chicken heart cytochrome c, while mutants containin the V92A mutation not any more.

表达纯化的、野生型的鸡脱血红素细胞色素c具有从鸡心细胞色素c化学制备的蛋白相同的折叠性质。

Unified color-coding of atoms, coenzymes, chemical classes, and cell organelles allows quick recognition of all involved systems, and computer graphics provide simulated 3D representation of many important molecules.

原子，coenzymes，化学种类和细胞细胞器的统一的彩色编码允许全部复杂的系统的迅速的承认，并且计算机图形提供类比的很多重要的分子的3D 代表。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
