概括
怀孕早期暴露在per-和多基物质 (PFAS) 中,与孕妇的氧化应激 (OS) 增加有关. 某些PFAS可能对OS生物标志物产生性别特异性影响,特别是8-基二氧化甘氨酸 (8-OHdG).
科学领域:
- 环境健康 环境健康
- 生殖毒理学 生殖毒理学
- 暴露和影响的生物标志物.
背景情况:
- 和多基基物质 (PFAS) 是广泛存在的合成化学物质,与不良妊娠结果有关.
- 潜在的机制包括内分泌干扰,氧化应激 (OS) 和炎症,但尚未完全理解.
研究的目的:
- 为了检查早期怀孕PFAS暴露和OS生物标志物之间的关联.
- 探索胎儿性别和母亲种族对这些关联的潜在影响修改.
主要方法:
- 在469名参与者的长度研究中,在整个怀孕期间测量了血PFAS和尿液中反复出现的OS生物标志物 (8-异醇,8-OHdG).
- 蛋白质损伤生物标志物测量为子集;统计模型调整为混因素.
- 对胎儿的性别和母亲的种族变化进行评估的相互作用术语.
主要成果:
- 对于PFOS和8-异质之间有积极的关联;对于PFUA,则有负面的关联.
- 表明MPAH和PFOA与8-异质的积极关联.
- 与8-OHdG的PFAS关联因胎儿的性别而异,女性的积极趋势,男性的零/负趋势. 没有观察到母亲的种族修饰.
结论:
- PFAS暴露与怀孕期间的OS增加有关.
- 有证据表明,某些PFAS对8-OHdG有潜在的性别特异性影响.
- 需要对多样化的种群,额外的生物标志物和饮食/行为修饰剂进行进一步的研究.

Types of Toxins
1.7K
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Peroxisomes
12.1K
Peroxisomes are specialized organelles present in fungi, plant, and animal cells. It can vary in number, size, morphology, and activity depending on the type of tissue and the nutritional state of the cell. For example, cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, have more peroxisomes than other cells in the body. Besides their primary role in breaking down complex organic molecules, peroxisomes can also synthesize specific macromolecules and participate in...

Teratogenicity
2.4K
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...
