概括
仅仅由组织学无法可靠地区分部分与二胎三胎妊娠,即使具有诸如水库形成之类的特定特征. 在35%-40%的病例中,准确诊断二三妊娠需要不仅仅是组织学评估.
科学领域:
- 生殖医学 生殖医学
- 妇科病理学 妇科病理学
- 遗传学 是一个遗传学.
背景情况:
- 区分二三胎妊娠 (部分) 和二胎三胎妊娠是非常重要的,因为前者有后胎妊娠 trofhoblastic 瘤的风险.
- 组织学评估是区分这些疾病的主要方法.
研究的目的:
- 评估是否结合异常组织学与 ploidy 基于分析的 triploidy 可以准确地诊断部分分子.
- 为了确定特定组织学特征的诊断效用,以区分二和二三妊娠.
主要方法:
- 一项基因型-表型相关性研究分析了20个二体和22个二体三体妊娠中的组织学参数.
- 四名观察员评估了组织学特征,以诊断三妊娠.
主要成果:
- 像小体大小≥2.5mm,水库形成,热囊细胞增生,和syncytiotrophoblast lacunae等特征在部分 (二三妊娠) 中更为常见.
- Cistern 形成显示高特异性 (96%),但适度敏感性 (70%) 的二三妊娠.
- 集水池与其他特征的组合实现了100%的特异性和PPV,但只有60%-65%的灵敏度.
结论:
- 没有单一的组织学参数是独一无二的,无论是二或二三妊娠.
- 仅仅通过组织学评估,就不足以准确地分类35%至40%的二三妊娠或部分.
- 水库形成是最重要的组织学歧视因素,但其与其他特征的结合仍然导致错过诊断.

01:21Nondisjunction
3.8K
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold...

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...

10.0K
Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also...
