- 阿尔茨海默氏症疾病研究研究
背景情况:
- 状纤维酸蛋白 (GFAP) 是大脑中星病的一个关键标志物.
- 星病与阿尔茨海默氏病 (AD) 的神经病理级联有关.
研究的目的:
- 为了调查血液中GFAP水平是否调解或缓解AD病理的核心体内病理之间的关系:β-粉样蛋白 (Aβ) 和tau.
- 探索GFAP与老化队列中神经退行性标记物的关联.
主要方法:

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
516
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...
