概括
人母乳中胡卜素的含量在整个哺乳期都会发生变化,而黄蛋白和黄素在晚些时候变得更为突出. 婴儿血中胡卜素水平与母乳不同.
科学领域:
- 营养科学 营养科学
- 新生儿科学 新生儿科学
- 生物化学 生化学
背景情况:
- 人母乳 (HM) 的成分对早产婴儿发育至关重要.
- 胡卜素,像黄蛋白一样,是具有抗氧化特性的重要微量营养素.
- HM类胡卜素的变化可能会影响婴儿健康结果,例如早产视网膜病变 (ROP).
研究的目的:
- 来自出生体重非常低至极低的早产婴儿的母亲的HM中胡卜素含量变化的特征.
- 调查这些婴儿中HM黄蛋白和ROP发生之间的关系.
主要方法:
- 从39名早产婴儿的母亲 (妊娠年龄24.2-29.6周) 收集了6周的HM样本 (n=184).
- 在HM和婴儿血 (n=21) 中测量了黄蛋白,紫素,β-胡卜素和柳科的度.
- 在ROP的母亲和非ROP的婴儿之间比较了胡卜素样本.婴儿.
主要成果:
- 随着哺乳期的持续时间,胡卜素度 (白蛋白,紫素,β-胡卜素,甘) 降低,在乳母乳中最高.
- 柳科和β-胡卜素在早期占主导地位,而黄蛋白和山丁在成熟的HM中增加.
- 在婴儿血中,与HM (28%) 相比,黄蛋白的比例更高 (58%).
- 在ROP的母亲和非ROP的婴儿之间,HM黄蛋白没有显著的差异.
结论:
- 人类母乳中的胡卜素含量是动态的,在不同母亲之间和整个哺乳期都会有所不同.
- 胡卜素的特征显著地从胆乳转移到成熟的牛奶.
- 婴儿血中胡卜素的分布不同于母乳中的分布.

Development of Human Microbiota
68
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...

Development of the Oral Microbiota
73
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
