概括
饮食中酸盐 (NO3-) 补充的好处是: 指尖血清样本可以评估血中酸盐 (NO3-) 和酸盐 (NO2-) 水平,尽管它们高估了静脉血值,酸盐评估更精确.
科学领域:
- 运动生理学 运动生理学
- 营养生物化学 营养生物化学
- 生物医学诊断 生物医学诊断
背景情况:
- 饮食中酸盐 (NO3-) 补充剂可增强氧化 (NO) 的产生,从而有可能改善健康和运动表现.
- 监测血液中酸盐 (NO3-) 和酸盐 (NO2-) 含量对于补充食NO3-.补充的人来说是有益的.
- 目前还缺乏一种简单且实用的方法来评估血液中的NO3和NO2.
研究的目的:
- 调查使用指尖血清样本作为传统静脉血样本的替代品,以评估血液中酸盐 (NO3-) 和酸盐 (NO2-) 度的可行性.
- 为了比较手指尖血清和静脉血之间NO3和NO2测量的准确性和相关性,在摄入甜菜汁后.
主要方法:
- 十名健康的年轻人摄入了140毫升含酸盐的甜菜汁.
- 指尖血清和静脉血样本在基线和每小时一次在摄入后长达4小时内收集.
- 在两种样本类型中测量了酸盐 (NO3-) 和酸盐 (NO2-) 的血度.
主要成果:
- 在指尖血清和静脉血之间,基线NO3和NO2水平相似.
- 摄入后,指尖血清显示NO3- (125-141%的静脉) 和NO2- (156-183%的静脉) 的水平高于静脉血.
- 摄入后的NO3-和NO2-均在指尖血清和静脉血之间观察到显著的相关性,除了NO3-在2小时和4小时之外.
结论:
- 指尖血清样本可用于评估酸盐 (NO3-) 和酸盐 (NO2-) 在食酸盐补充剂后的血水平.
- 虽然指尖血清高估了静脉血值,但它为监测这些代谢物提供了切实可行的替代方案.
- 与静脉血测量相比,指尖血清中的酸盐 (NO2-) 评估似乎比酸盐 (NO3-) 评估更精确.

Inorganic Nitrogen Assimilation
5
Nitrogen is an essential element in biological systems, forming a crucial component of proteins, nucleic acids, and other cellular constituents. Many bacteria and archaea acquire nitrogen in the form of nitrate (NO₃⁻) or ammonia (NH₃), which are then assimilated into biomolecules through specific enzymatic pathways.Assimilatory Nitrate ReductionWhen nitrate enters the cell, it undergoes a two-step reduction process known as assimilatory nitrate reduction. Initially, the enzyme...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
61
Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
