呼吸作用

Electrons are transferred from succinate to ubiquinone through the buried prosthetic groups flavin-adenine dinucleotide; the [2Fe-2S], [4Fe-4S], and [3Fe-4S] clusters; and heme b cofactors.

复合物II作为一个完整的膜蛋白复合物在三羧酸循环和有氧呼吸链两个系统中起着积极的传递作用。

Choice 36 carbon monoxide poisoning sufferer,application BIPAP breath machine assistance ventilate treatment,and with through nose pipe give oxygen treatment carry on comparison.

选择36例一氧化碳中毒患者，应用BIPAP呼吸机辅助通气治疗，并与经鼻导管给氧治疗者进行比较。结果：治疗组治疗后4h PaO2及。。目的：探讨采用经面罩正压机械通气给氧治疗急性重度一氧化碳中毒患者的作用。

Objective To study the mechanisms and expressions of Fas/FasL in the lungs,spleens and lymph nodes of SARS patients.

目的观察并探讨凋亡相关基因Fas/FasL在严重急性呼吸综合征病变组织肺、脾、淋巴结中的表达及其在SARS发病中的作用。

Most of insects usually don not have the hemcoyte for transporting oxygen, the respiratory of insect is chiefly accomplished by the tracheal system that spreads all over the whole body. Outside oxygen enters the tracheal system through spiracles arranged in two sides of body and is transported through trachea and tracheoles to meet directly the needs of tissues.

一般认为大多数昆虫体内没有运输氧的血细胞存在，昆虫呼吸主要是靠遍布全身的气管系统来完成，O2靠扩散作用由分布于昆虫身体两侧的气门处进入，经气管、微气管的运输而直接给组织供氧。

As inhibition at the terminal oxidases did not reduce the electrochemical response, it is probable that the mediator interacted at the respiratory chain before the terminal oxidases.

当作用于末端氧化酶的抑制作用没有减轻电气化反映时，有可能是介质相互作用于末端氧化酶之前的呼吸链。

Results showed that the activity of soil poly-phenol oxidases and acid phosphatase, and soil respiration were suppressed by Starane at 0.5 and 5 mgkg^(-1) dry soil, respectively, during the first several days of experiment, but were slight promoted thereafter. In contrast, treatment with Starane at 50 mgkg^(-1) stimulated at the beginning of experiment but inhibited following that time the activity of soil poly-phenol oxidases and acid phosphatase and soil respiration. Activity of urease was stimulated at the beginning but inhibited in the following days by Starane at 0.5 and 50 mgkg^(-1) dry soil, respectively. However, the pattern of stimulation of urease activity at first several days of experiment followed by reduction to the basil level was observed. With respect to invertase, its activity was constantly depressed in the presence of Starane.

结果表明使它隆在0.5mgkg^(-1)和5mgkg^(-1)质量分数时对土壤多酚氧化酶、酸性磷酸酶和呼吸强度的影响为轻微抑制－激活－恢复稳定的趋势，50mgkg^(-1)质量分数时为轻微激活－抑制－恢复稳定的趋势；使它隆在0.5mgkg^(-1)和50mgkg^(-1)质量分数时对土壤脲酶活性的影响为激活-恢复稳定的趋势，5mgkg^(-1)时则处于抑制－激活的趋势；各质量分数的使它隆浓度对土壤蔗糖酶和土壤全酚均为抑制作用，且质量分数越大抑制越强烈。

Objective To evaluate the effect of hand hygiene in the prevention of ventilator-associated pneumonia in neonates.

目的 探讨手卫生在新生儿呼吸机相关肺炎预防中的作用。

Installation of two outer openings each staggered 180b, the inner and outer openings staggered opening 90b, and pin the three rings with a fixed, outer and inner expansion force in self-expansion force of working together, close to the surface of the pump cylinder run, inflation is not only the axial ring sealed, and the radial seal Ye Hao, it prevents micro-fine sand and into the axial friction pair, can also prevent the micro-fine sand and into the internal voids in the inner ring 3, the operation will not impede expansion ring breathing.

安装时2个外环开口互错开180b，内环开口与外环开口错开90b，并用销钉将3个环固定，外环在自身胀力和内环胀力共同作用下，紧贴泵筒内表面运行，胀圈不但轴向密封好，而且径向密封也好，故阻止微细砂进入轴向摩擦副，也可阻止微细砂进入内环3的内部空隙中，不会阻碍胀圈运行中呼吸。

The central respiratory chemoreceptors that is widely distributed in medulla oblongata can adjust the excitability of the neurons located in respiratory center of brain stem by sensing the changes of pH and the concentration of CO2 in brain, therefore , it plays an important role in keeping acid-base balance rapidly and maintaining homeostasis in vivo.

脑内pH和CO2的变化通过中枢化学感受器(central chemoreceptors，CRCs)调节脑干呼吸中枢的兴奋性，其在快速调节机体酸碱平衡以及内环境稳定的过程中发挥着重要作用。

Alpha-2 agonists induced hypoxemia is an effect that is specific for ungulates and has neer documented in humans.

此外，Bissonnette[6]建议认为，胎儿和新生儿出现急性缺氧时的呼吸反应可被蓝斑核内的作用于α-2受体的儿茶酚胺所减弱。

Life. But the intrinsic way of the Internet by wire confines accessing and using of the network information.

然而，Internet固有的有线连接方式大大限制了人们对网络信息的访问和使用。

I have a strong persuasion that this is true .

我坚信这是正确的。
