- 代谢学
- 睡眠医学
背景情况:
- 阻塞性睡眠呼吸暂停 (OSA) 是一种普遍的睡眠障碍.
- 人们越来越认识到肠道微生物在OSA病变中的作用.
- 慢性间歇性缺氧 (CIH) 是OSA的一个标志,可能会影响肠道健康.
研究的目的:
- 在阻塞性睡眠呼吸暂停 (OSA) 中调查肠道微生物群和代谢物概况.
- 评估这些特征作为OSA诊断和严重性的生物标志物.
- 探索慢性间歇性缺氧 (CIH) 中肠道变化和临床指标之间的相关性.
主要方法:

- 分析了肠道微生物的组成和功能.
- 评估了临床指标,OSA严重程度和肠道菌群/代谢物之间的关联.
主要成果:
- OSA和CIH组表现出肠道微生物群的变化,Firmicutes和Tenotrophomonas的增加,以及Bacteroidota和Ligilactobacillus的减少.
- 在OSA和CIH组中观察到Nervonic acid和Erucic acid水平升高,同时Arachidonic acid水平降低.
- 在特定细菌 (例如,Coprobacillus,Bacteroidota,Lactococcus) 和临床指标 (例如,淋巴细胞,eosinophilia,中性粒细胞,AHI) 之间发现了显著的相关性.
结论:
- 慢性间歇性缺氧 (CIH) 诱导显著的肠道微生物和代谢物失调.

Metabolism of Chemolithotrophs
167
Chemolithotrophs are microorganisms that obtain energy by oxidizing inorganic molecules such as hydrogen gas (H₂), ammonia (NH₃), reduced sulfur compounds (H₂S, S²⁻), and ferrous iron (Fe²⁺). Unlike heterotrophic organisms that rely on organic carbon, chemolithotrophs transfer electrons from these inorganic donors to the electron transport chain (ETC), generating a proton motive force (PMF) that drives ATP synthesis through oxidative phosphorylation.

Metabolic States of the Body: Fasting and Starvation
1.8K
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...
