概括
评估了鼻氧化 (nNO) 水平,以诊断过敏性鼻炎 (AR). 研究人员发现nNO不是一个可靠的独立生物标志物来区分AR与非过敏性鼻炎 (NAR).
科学领域:
- 过敏学 过敏学
- 肺部病理学 肺部病理学
- 生物标志物研究 生物标志物研究
背景情况:
- 氧化 (NO) 的升高与过敏性喘等炎症状况有关.
- 分数呼出的NO是喘中2型炎症的已知生物标志物.
- 对于过敏性鼻炎 (AR) 的鼻NO (nNO) 的诊断效用仍未得到充分研究.
研究的目的:
- 研究nNO作为区分AR与非过敏性鼻炎 (NAR) 的潜在生物标志物.
主要方法:
- 一组患有鼻炎症状的医学学生接受了问卷,病史审查,临床检查,皮测试 (SPT) 和nNO测量.
- 使用NIOX VERO便携式氧化分析仪测量nNO水平.
- 在花粉季节对14种区域性过敏原进行了SPT.
主要成果:
- 在122名志愿者中,62人报告了鼻炎症状;39人有SPT确认的AR,23人被归类为NAR.
- 在AR组中,平均nNO度为830±247ppb,在NAR组中为851±373ppb.
- 在AR和NAR组之间没有观察到平均nNO度的统计学上显著差异.
结论:
- nNO不是一个可靠的独立生物标志物来诊断过敏性鼻炎.
- 可能需要进一步的研究来探索其他潜在的角色或AR诊断生物标志物的组合.

Nitric Oxide Signaling Pathway
4.9K
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers
39
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...
