背景情况:
- 阿尔茨海默氏症 (AD) 是一个重大的全球健康挑战,需要更深入地了解其分子病原性.
- 卡利克林相关酶 (KLKs) 是一种血清蛋白酶家族,正在成为潜在的生物标志物和阿尔茨海默病的治疗标.
- 虽然已经研究了KLK6和KLK8,但关于KLK5在AD病变发生过程中的作用的信息仍然有限.
研究的目的:
- 为了研究阿兹海默症患者脑脊液 (CSF) 中KLK5的水平.
- 探索KLK5度与已确定的AD生物标志物之间的关联.
主要方法:
- 脑脊液 (CSF) 样本从AD患者和认知正常个体中收集.

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...
