概括
产前暴露于像双和酸盐这样的内分泌干扰化学物质与较低的sFlt-1/PlGF比率有关,这表明对胎盘健康有复杂的影响. 需要进一步的研究来理解这些意想不到的发现.
科学领域:
- 环境健康 环境健康
- 生殖生物学 生殖生物学
- 内分泌学 在内分泌学.
背景情况:
- 胎盘发育依赖于像胎盘生长因子 (PlGF) 这样的生长因子和像可溶性fms-like tyrosine kinase-1 (sFlt-1) 这样的抑制剂.
- 在母体血清中sFlt-1/PlGF比率升高预测了孕前.
- 暴露于常见的内分泌干扰化学物质双醇和酸盐,已与孕前有关.
研究的目的:
- 调查怀孕期间尿道双和甲酸盐代谢物度与血清sFlt-1,plGF之间的关系,以及它们的比例.
- 探索内分泌干扰化学物质暴露和胎盘血管原生生物标志物之间的潜在联系.
主要方法:
- 在怀孕期间,双醇和酸盐代谢物的尿度被测量了多达三次.
- 用线性混合模型分析了sFlt-1和PlgF的血清度,并根据妊娠年龄进行了调整.
主要成果:
- 双A和双S的较高度与较低的sFlt-1,较高的PlGF和较低的sFlt-1/PlGF比率有关.
- 甲酸代谢物也与较高的plgf和较低的sflt-1/plgf有关,特别是在怀孕20周后.
结论:
- 在产前双和酸盐暴露和较低的sFlt-1/PlGF比率之间观察到的关联是意想不到的.
- 这些发现表明,内分泌干扰化学物质可能对胎盘健康产生比以前通过血管原生生物标志物理解的更复杂的影响.

3.9K
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...

01:07Development of Blood Vessels

The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...
