Germ-line mutations in the genes hTERT and hTR, encoding telomerase reverse transcriptase and telomerase RNA, respectively, cause autosomal dominant dyskeratosis congenita, a rare hereditary disorder associated with premature death from aplastic anemia and pulmonary fibrosis.

端粒酶逆转录酶的编码基因hTERT和端粒酶RNA的编码基因hTR发生种系突变时，可引起常染色体显性先天性角化不良，这是一种罕见的遗传性疾病，它与再生障碍性贫血和肺纤维变性所致的早产儿死亡具有相关性。

Compared with the conventional emulsion polymerization system,the latices that are of monodispersed latex particles of 0.5m m in diameter,low viscosity and high storage stability are prepared by emulsifier-free emulsion polymerization.

实验结果表明，与常规乳液聚合体系相比，所获得的无皂乳液的乳胶粒大小均一，粒径在0.5m m左右，粘度低，储存稳定；共聚物呈完全无规立构，玻璃化转变温度均在25℃附近，拉伸强度明显增大，耐水性和剥离强度显著提高。

We think main metamorphic rock types of this area include mited granite ,mixed metamorphic rock,leptite,etc.

认为变质岩中混合花岗岩、混合岩化变质岩、变粒岩、浅粒岩、黑云斜长片麻岩等为本区的主要变质岩类型；沉积岩以云岩、硅质岩和石英砂岩为主；火成岩脉主要为辉绿岩、煌斑岩和闪长玢岩。

The zircon was dated by using the technique of single-zircon stepwise evaporation-deposition with a thermal ion mass spectrometry (Bernd Kober, 1986 and 1987). The zircon ages are 2.60-2.54 Ga for biotite-leptynite, 3.36-2.62 for mimatized leptite, and 3.53-3.08 Ga for quartzite from the iron formation.

用热离子质谱计双带源蒸发—沉积测定单个锆石晶体年龄的方法对弓长岭含铁建造中黑云变粒岩、混合岩化浅粒岩和石英岩中的锆石作了测定，获得了2.60—2.54 Ga，3.36—2.62 Ga和3.53—3.08 Ga等年龄数据。

The results show that the2 0～ 40 cm and40～ 60 cm layers for the red loessial soil and2 0～ 40 cm layer for the red loessial soil had a large amount of easily mineralizable nitrogen besides the0～ 2 0 cm layer, but the easily mineralizable nitrogen was little...

总体上看，红油土中氮素的矿化和硝化作用强于红垆土。铵态氮肥在粘粒含量少、有机质含量高土层中的迅速减少主要归咎于硝化，而在粘粒含量多、有机质含量少的土层，主要取决于矿物固定

The mechanical properties of coal filled polymer composites The mechanical properties of coal/PP composites were investigated, and the effects of coal rank, particle size, surface modification of coupling and alkylation were discussed. The results show that the anthracite and bituminous coal all can be used as filler of plastic after pretreatment of part devolatilization and surface modification; The modulus of composites increase with the content of coal filler; The coupling agent is of no effect for reinforcing the coal/PP composites, except that there are new oxygenous function group forming on the surface in the process of pulverizing; The F-C alkylation reinforce coal (under 10μm)/PP composites obviously.

4煤填充高分子复合材料力学性能超细煤粉填充聚丙烯复合材料力学性能的研究结果表明，烟煤和无烟煤经过脱除部分挥发分的预处理后，都可用于与塑料共混制备复合材料；偶联剂改性对低变质程度烟煤/聚丙烯复合材料的力学性能基本不起改善作用，而对于经气流超细粉碎后的小粒径高变质程度烟煤及无烟煤则有一定的增强作用；烷基化改性在煤表面接枝了烷基，使平均粒径小于10μm的煤/聚丙烯复合材料拉伸屈服强度普遍提高，煤填充高分子复合材料可在较高含煤量情况下维持良好的力学性能。

Colloidal gold was reductively prepared by sodium citrate,sodium citrate-tannin,ascorbic acid and sodium borohydride respectively.And corresponding gold particles size,morphology,dispersion,and stability of the samples were characterized and compared.

分别采用柠檬酸钠还原法、柠檬酸钠-鞣酸还原法、抗坏血酸还原法、硼氢化钠还原法4种方法制备了粒径为十几纳米的胶体金，并对制得的纳米胶体金粒径大小、分散度、稳定性及形貌进行了表征和比较分析。

Previous study showed that over-expression of PICK1 in human leukemia REH cells rendered a higher resistance to etoposide-induced apoptosis through a recruitment of PKC alpha which resulted in maintenance of mitochondrial membrane potential, an enhanced phosphorylation of the anti-apoptotic Bcl-2 protein at Ser70, and inhibition of Bax dimerization.

在本实验室先前的研究，於人类血癌REH细胞中过度表现PICK1蛋白质，PICK1能够藉由招揽蛋白激酶C alpha至粒线体上，引起Bcl-2磷酸化程度提高，抑制Bax蛋白二聚体的形成，进而稳定粒线体的膜电位，以至於细胞对於化疗药物etoposide引起的程式凋亡具有抗药性。

So, in theory, a decadal repopulation of all our stem cell populations with new ones whose telomeres had been restored, but which had no telomerase or ALT genes of their own, should maintain the relevant tissues indefinitely while preventing any cancer from reaching a life-threatening stage.

因此，在理论上，若我们所有的干细胞群体的端粒已被恢复、但没有端粒酶或自己的 ALT 基因，那么10年的重新群体化将在长时期内维持相应组织而防止达到威胁一定生命阶段的任何癌症。

The recombinant plasmid DNA of PrM-E gene but not unmethylated CpG was capable of inducting antibodies against D2-43 virus.

我国登革2型病毒PrM-E基因重组质粒DNA具有一定的免疫原性。在本实验条件下，含非甲基化细菌性CpG的pUC19质粒DNA，对PrM-E基因的DNA免疫效果没有促进作用。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
