概括
植物性饮食 (PBD) 与阿尔茨海默病 (AD) 生物标志物有关联. 虽然一些PBD表明粉样蛋白负担较低,但与常规肉食者 (RME) 相比,其他PBD显示不同AD生物标志物的水平较高.
科学领域:
- 神经科学是一个神经科学.

- 生物标志物研究 生物标志物研究
背景情况:
- 新兴研究表明,植物性饮食 (PBD) 可能会提供神经保护,防止像阿尔茨海默病 (AD) 这样的神经退行性疾病.
- 本研究调查了与常规肉食饮食 (RME) 相比,习惯性PBD和基于血的AD生物标志物之间的关系.
研究的目的:
- 检查各种植物性饮食模式与基于血液的阿尔茨海默病 (AD) 主要生物标志物之间的关联.
- 为了将这些关联与常规食肉 (RME) 饮食模式进行比较.
主要方法:
- 植物性饮食研究的二次分析,涉及237个血样本.
- 使用超敏感单分子阵列 (SIMOA) 测量Aβ1-42/Aβ1-40比率,p-tau181,NFL和GFAP.
- 进行了根据年龄和性别调整的多变量回归分析.
主要成果:
- 与RME相比,在pesco-vegetarian (PVs),lacto-ovo vegetarian (LOVs) 和半素食 (SVs) 组中观察到较高的血Aβ1-42/Aβ1-40比率.

749
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

01:19Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

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...
