暴露在乙醇中的斑马鱼胚胎显示出发育问题,包括发育不良和化减少. 研究人员还在胚胎中检测到乙醇代谢物,乙烯基葡萄化物 (EtG) 和乙烯硫酸盐 (EtS).
科学领域:
- 发展生物学 发展生物学
- 毒理学 毒理学 毒理学
- 斑马鱼模型 斑马鱼模型
背景情况:
- 怀孕期间接触乙醇会导致胎儿酒精综合征 (FAS) 和胎儿酒精谱系障碍 (FASD).
- 动物模型对于了解FASD病因至关重要.
- 斑马鱼 (Danio rerio) 为研究发育毒性提供了一个新且有前途的模型.
研究的目的:
- 调查乙醇暴露对斑马鱼胚胎发育的影响.
- 为了确定是否能在斑马鱼胚胎中检测到非氧化乙醇代谢物,乙烯葡萄糖化物 (EtG) 和乙烯硫酸盐 (EtS).
- 探索斑马鱼中乙醇度和代谢物水平之间的关系.
主要方法:
- 斑马鱼胚胎暴露于不同度的乙醇 (0.5%,1.5%,2.5%v/v).
- 评估了发育参数,包括发育不良,身体长度,宽度,心率和化率.
- 斑马鱼胚胎中的EtG和EtS度使用分析技术进行测量.
主要成果:
- 乙醇暴露导致显著的发育异常,包括心周/黄囊,身体曲,尾巴,以及化率降低.
- 观察到身体长度,身体宽度和心率的统计学意义上的差异.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...

Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...
