查询词典 hypoxia

Methods The chemical hypoxia was induced by incubation of U251 cells with cobalt chloride.

以氯化钴模拟缺氧，采用RT-PCR、免疫细胞化学方法分别检测缺氧诱导因子-1α和血管内皮生长因子mRNA和蛋白的表达，鸡胚绒毛尿囊膜模型检测缺氧时胶质瘤细胞血管生成情况。

HIF-1αprotein expression is related to hypoxia degree mimicked by cobalt chloride and related to exposure time. HIF-1αmRNA expression had no significant difference in all groups. Cobalt chloride induced HIF-1αexpression is at protein level, no transcription level.

1、HIF-1α蛋白表达与氯化钴模拟缺氧程度和时间有关，HIF-1αmRNA表达没有明显差异，提示氯化钴模拟缺氧诱导的HIF-1α调节可能发生在蛋白水平，而非转录水平。

Simulated 2 km intermittent hypoxia (4 hours/day, continuation for 2 days), cold, restraint and their compound stresses did not obviously influence rats insulin secretion.

1。模拟2km间歇低氧(4小时／天，连续2天)、低温、束缚及其复合应激对大鼠胰岛素分泌无明显影响。

However, simulated 5 km intermittent hypoxia (4 hours/day, continuation for 15 days) significantly inhibited rats body weight gain.

单独冷应激、模拟2km低氧应激(4小时／天，连续2天)+冷应激、2km低氧应激、2km低氧应激+束缚应激和单独束缚应激都明显抑制大鼠体重的增重，其中束缚应激的抑制作用最为明显，可是对大鼠血浆胰岛素水平无明显影响。

Obstructive sleep apnea hypopnea syndrome is a clinic syndrome charactered with repeated apnea hypopnea,intermittent hypoxia,frequent arousals during sleeping at nightwhether companied with hypercapnia or not.

阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome，OSAHS)以睡眠时反复呼吸暂停、间歇性低氧、睡眠结构紊乱和反复微觉醒为特征，伴或不伴低通气的临床综合征。

It is now known that seere hypoxia-ischemia may not cause immediate cell death, but may precipitate a complex biochemical cascade leading to the delayed deelopment of neuronal loss. These phases include a latent phase after reperfusion, with initial recoery of cerebral energy metabolism but EEG suppression, followed by a secondary phase characterized by accumulation of cytotoxins, seizures, cytotoxic edema, and failure of cerebral oxidatie metabolism from 6 to 15 h post insult.

现在认识到严重的局部缺氧有可能不立即引起细胞坏死，但是可能促成一种复杂的生化级联反应，这可能导致神经元丢失，进而导致延缓发育，这些时期包括再灌注后的潜伏期，该期出现早期的脑能量代谢复苏但脑电图却呈抑制状态，紧接着第二期表现为损伤后6－15个小时细胞毒素，癫痫，细胞毒性水肿，脑氧化功能衰竭的累积。

bFGF enhances the tolerance to hypoxia of aged rat cardiomyocytes and the activation of ERKs is involved in the protective mechanism.

bFGF可以提高老年大鼠心肌细胞对于缺氧的耐受性，其保护机制涉及ERKs的活化。

Pregnant women with iron deficiency, easily caused by anemia, decreased hemoglobin led to tissue hypoxia, severe cases can cause cardiac hypertrophy, heart failure, edema and so on, iron-containing foods have more liver, Kidneys, lean meat, soy products, spinach, celery, carrots, seaweed, black fungus, fish, eggs and so on.

孕妇缺铁，易引起贫血，血红蛋白下降导致组织缺氧，严重者会造成心肌肥大、心力衰竭、浮肿等，含铁多的食物有猪肝、猪肾、瘦肉、豆制品、菠菜、芹菜、胡萝卜、海带、黑木耳、鱼类、鸡蛋等。

Objective To investigate whether hypoxia preconditioning exist in adipose tissue,and construct the hypoxemic model of adipose tissue.

目的 探讨脂肪组织中是否存在缺氧预适应现象，构建CoCl2致缺氧的缺氧模型。

Method of interval ordinary pressure hypoxia can successfully construct hypoxemic pulmonary hypertensive mouse model.

Fancy gold-plated dangling earrings with facetted White Opal crystals.

花式镀金悬垂耳环与facetted白欧泊水晶。

This essay chooses the study aim from biology teachers in middle school in Shi Jiazhuang which tells us that most of the middle school biology teachers in Shi Jiazhuang have the"burnout", lower successfulness, individualize.

本文选取石家庄市初中生物教师作为研究对象，运用问卷调查的方法对石家庄市初中生物教师职业倦怠的现状进行调查，调查结果发现，石家庄市初中生物教师这一群体普遍存在职业倦怠，情感枯竭程度偏高，成就感偏低，去个性化程度最为严重。
