- 生物标志物开发 生物标志物开发
背景情况:
- 需要敏感的生物标志物用于认知功能,特别是在早期痴呆阶段,如轻度认知障碍 (MCI).
- 以前的研究表明,Fastball是一种脑电图 (EEG) 方法,对阿尔茨海默病的认知功能障碍敏感.
- 这项研究调查了Fastball对MCI患者记忆障碍的敏感性.
研究的目的:
- 验证快球作为轻度认知障碍 (MCI) 中识别记忆功能障碍的敏感生物标志物.
- 评估Fastball能够区分有记忆力和没有记忆力MCI以及健康对照者的能力.
- 评估Fastball的测试复试可靠性及其对一年内认知能力下降的预测价值.
主要方法:
- 53名MCI患者和54名健康对照人接受了为期3分钟的快球EEG任务,测量被动识别记忆.
- 参与者还完成了标准的神经心理测试,用于记忆,注意力和一般认知.
- 测试复试可靠性和纵向变化在一年的随访期内进行了评估.
主要成果:
- 与无记忆力MCI患者和健康对照患者相比,无记忆力MCI患者的快球反应明显较低.

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
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...

Blood 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...
