缺氧的

Therefore, tumors in general are always exposed to hypoxia and poor nutrition because of insufficient vascularization.

同时，由于血供不足，肿瘤细胞通常处于一种缺氧和营养缺乏的环境中。

Thus, the data suggest that ERK1/2 signaling pathway is involved in 15-HETEinduced hypoxic pulmonary vasoconstriction.

由此表明ERK1/2信号转导通路参与15-HETE收缩缺氧大鼠肺动脉的过程。

Thus, the data suggest that ERK1/2 signaling pathway is involved in 15-HETE-induced hypoxic pulmonary vasoconstriction.

由此表明ERK1/2信号转导通路参与15--HETE收缩缺氧大鼠肺动脉的过程。

Background— It has been proposed that under hypoxic conditions, nitrite may release nitric oxide, which causes potent vasodilation.

背景——过去已经提出，在缺氧条件下，亚硝酸盐会释放引起有效血管舒张的一氧化氮。

Nitric oxide is an important vasodilator. Reports on the changes of NO during HPV are controversial.

缺氧时PKC的激活可能在脑eNOS基因表达增强中起调控作用。

Objective: To construct pEGFP-Ngb expression vector and to investigate its function in SY5Y cells under hypoxia condition.

目的 构建pEGFP-Ngb荧光表达载体并研究其在缺氧条件下SY5Y细胞中的功能。

If the retina has oxygenpoor severely, such as microaneurysm, little bleeding point cumulated, severe intraretinal microvascular abnormality, veinlet formed obviously, we can use PRP more times to cure diabetic retinopathy.

如果存在严重视网膜缺氧征象，即出现小动脉瘤、微小出血点积聚、严重的视网膜内微血管异常和小静脉明显形成时，可多次重复应用全视网膜光凝治疗糖尿病视网膜病变。

Activin mRNA increased at 1 h but not 4 or 24 h after hypoxia, similar to the time course of erythropoietin and vascular endothelial growth factor induction.

在缺氧后 activin mRNA 增加不是在1小时，而是在4或24小时，这个时间类似于促红细胞生成素和血管内皮生长因子介导的过程。

To investigate the expressions and the roles of activin A on brain tissue in neonatal rats with hypoxia and ischemia.

探讨激活素A(activin A，ACT A)在新生大鼠缺氧缺血性脑损伤(hypoxic ischemic brain damage，HIBD)中的表达规律及其意义。

Objective This study is to investigate the expression of VEGF after exposure of human osteoblasts to anoxic stimuli .

目的 探讨缺氧对人成骨细胞 VEGF表达的影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
