概括

胎盘拥有独特的微生物群,根据妊娠阶段和位置而有所不同. 过早分娩与特定的细菌转移有关,突出显示了胎盘失生症和不良妊娠结果之间的潜在联系.

科学领域:

微生物学微生物学
产科产科产科产科产科
基因组学就是基因组学.

背景情况:

胎盘在历史上被认为是无菌的,但最近的证据表明存在微生物群落.
了解胎盘微生物组的动态性质对于母亲和胎儿的健康至关重要.

研究的目的:

为了研究胎盘微生物组在整个妊娠期间的时间和空间变化.
为了比较胎盘微生物特征在早产和产后.

主要方法:

一个病例控制研究,涉及孕妇早产或产期分娩.
使用QIIME和R. 来分析来自胎盘部位 (基底板,胎儿膜,小) 的微生物概况.
定量PCR (Q-PCR) 检测绝对细菌的数量和验证.

主要成果:

根据传递方式,细菌群落没有显著差异.
低丰度的细菌,特别是在早产样本中丰富的细菌,被Q-PCR检测到.
胎盘细菌的组成随着妊娠而变化,显示了蛋白质细菌和坚固菌的增加.
在胎盘位置和妊娠阶段观察到不同的细菌样本,Ralstonia insidiosa始终在基底板中发现.

结论:

胎盘拥有自己独特的微生物组,在术后和早产样本之间存在差异.
细菌失生症可能在早产中起作用,需要进一步调查.
区分病态细菌与天然的胎盘微生物群对于临床应用至关重要.

Anatomy of the Intestines

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...
