- 为了比较双胞胎的胎儿生长轨迹 (双胆子和单胆子) 与单胎妊娠.
- 为双胞胎提供孕期年龄和胆性特定的EFW百分位数.
主要方法:
- 利用了来自四个欧洲中心的4391例双胞胎怀孕的数据.
- 应用等级模型到单元Z分数,考虑序列相关性.
- 使用哈德洛克公式,从第一季度的冠状长度和EFW中推导出妊娠年龄.
主要成果:
- 双胞胎胎在怀孕早期比单胞胎小,直到大约24周才有追赶成长.
- 双 (DC) 和单双 (MCDA) 双胞胎在24周后都表现出增长减缓.
- 在36周时,DC双胞胎的第50百分位EFW处于第22个单独百分位,而MCDA双胞胎则处于第12个单独百分位.
结论:
- 在双胞胎怀孕中,胎儿的生长减少,特别是在MCDA病例中,与单独怀孕相比.
- 双胞胎和单胞胎之间生长轨迹的差异随着24周后的妊娠年龄增加.
- 由此得出的参考分布有助于临床评估双胞胎妊娠中的胎儿生长.

1.0K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:07Teratogenicity
2.5K
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...

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...
