查询词典 metabolism

We suppose that there is a presently undefined subfraction of stem cell population that exists in a number of tissues beyond embryonic development. We term them postembryonic pluripotent stem cells. They differ from embryonic stem cells in that they gradually lose some differentiation potentials during development and adopt some special phenotypes once within a certain tissue. They can give rise to different kinds of stem cells; therefore, help to maintain balance during development and metabolism. They provide cells not only for the damaged tissues they reside, but also for damaged tissues different from them by migration triggered by proinflammatory cytokines or growth factors.

我们认为在胚胎发育后的多种组织中都存在一类原始干细胞群体，它们和造血干细胞、神经干细胞等多能干细胞不同，后者只能分化为特定胚层的细胞，而这类原始干细胞可分化为不同胚层的组织细胞；另一方面，它们区别于胚胎干细胞，在妊娠期间会逐渐失去部分分化潜能，并且会出现一些特殊表型或者分子标志，我们称其为胚胎后亚全能干细胞，这类干细胞具有下列特性：可分化为不同胚层的细胞，分布于身体的所有组织和器官，具有相同的表型或标志；他们在胚胎期存在于一些或全部的组织和器官中，可分化为不同类型的多能干细胞并在生长发育和新陈代谢中维持这些多能干细胞保持平衡；可以参与机体自我修复和更新，不仅能分化为所在器官的组织特异性细胞，参与器官重塑，也可以在炎症因子或者生长因子的趋化作用下，远处转移修复受损组织。

Results showed that 85% of the preflowering assimilation product was used in energy metabolism and organ forming.

结果表明：花前期大豆的同化产物，以其85％用于后续生育的能量代谢和器官建造；而后期豆荚和子粒的物质，约70％系来源于后期的同化产物，余者为前期同化产物的再分配。

We preiously reported that high intake of milk, but not meat, equal in protein content, increased serum insulin-like growth factor-I in prepubertal boys. sIGF-I plays a key role in bone metabolism.

我们以前曾报道，在蛋白含量相同的情况下，牛奶的高摄取较肉类的高摄取更能增加青春期前男童血浆胰岛素样生长因子水平。sIGF－Ⅰ在骨代谢中扮演了重要的角色。

IL possesses the protective effects on procerebrum ischemia/reperfusion injury in mice and its mechanism may be related to anti-oxidant action and improvement of the energy metabolism.

IL对实验性前脑I/R损伤的保护作用机制可能与减少脑组织和脑细胞线粒体中过氧化物和氧自由基含量，增高SOD活性及改善ATPase活性有关。

Polysomes change in number as "few-many-few-many" during the development of the egg, early zygote stage, zygote at dormancy, zygote in prophase of mitosis and two-celled proembryo in sugar beet, which indicates that such changes in metabolism as "low-high-low-high" activity may relate to the transformation from gametophyte to sporophyte generation.

根据上述结果可以得出，栽培甜菜从卵细胞成熟→合子初期→合子休眠期→合子分裂前期→二细胞原胚的超微结构变化中多聚核糖体的变化最为显著，表现为&少→多→少→多&的数量变化过程，反映出细胞代谢状态也经历了&弱→强→弱→强&的变化过程，这种变化趋势与配子体世代向孢子体世代转变有关。

Under hypoxic conditions,prolyl hydroxylase activity decreases because they require oxygen as a co-factor and the HIF-1αprotein is stabilized.HIF-1αstabilization is followed by activation of the transcription of numerous target genes such as vascular endothelial growth factor,erythropoietin,and glucose transporter 1 (Glut-1) that are involved in angiogenesis,erythropoiesis,energy metabolism and cell survival.

但是，MSCs改善心功能的能力有限，大量的证据表明MSC移植对心功能的改善是轻中度的，大部分研究结果显示MSCs移植对心功能的改善只有5-6%左右，甚至有些临床试验没有观察到心功能的改善，这远远达不到我们的预期，其中一个很重要的原因是绝大多数的细胞移植到体内后在很短的时间内发生死亡，研究报道90%的MSCs在移植后的1天内死亡。

In high dentity fermentation, the cellular respiration, energy metabolism, highest bacterial density and dry bacteria weight of the G830 strain were markedly better than control strains PA1 and BL21, The expression of recombinant prolyl endopeptidase in G830 and PA1 under the above condition was high and stable. Their growth situation and fermentation parameters were similar with their parental strains without plasmids, and resided plasmids maintained stably in those strains.

在高密度发酵条件下，G830的细胞呼吸强度、能量代谢、最高菌密度和细胞干重，均明显优于对照菌株PA1和BL21；重组蛋白脯氨醯内肽酶在G830和PA1中获得稳定高表达；重组菌生长状况及发酵指标均与空宿主菌基本一致且表达质粒能维持较好的稳定性。

The effect of different ratios of propionic/acetic acid on the metabolism of long-term cultivated GAO was investigated.

在3个SBR反应器（即SBR-A，SBR-C和SBR-E）中，以3种不同比例的丙酸/乙酸中长期驯化活性污泥使之富集聚糖菌，对丙酸/乙酸对聚糖菌的长期和短期代谢的影响进行了研究。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
