背景情况:
- 接触运动中重复的头部冲击 (RHI) 是神经退行性疾病 (如慢性创伤性脑病变 (CTE)) 的危险因素.
- 人们还没有完全理解RHI和神经退行症之间的病理联系,但炎症越来越多.
- 之前的研究表明,脑震荡后炎症性细胞因子升高.
研究的目的:
- 为了比较前职业接触体育运动员与RHI (ExPro) 的炎症概况,与阿尔茨海默病 (AD) 患者和健康对照 (HC) 相比.
主要方法:
- 使用多重近距离延伸试验 (PEA) 来量化脑脊液 (CSF) 中的737种炎症蛋白.

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...
