- 放射学 放射学是一门学科.
- 病理学 病理学 病理学
背景情况:
- 胸膜 (CP) 通过清除废物来维持大脑的平衡.
- 阿尔茨海默病 (AD) 涉及由于清除受损而导致有毒副产品的积累.
- 在AD中疑似CP变化,但未确立.
研究的目的:
- 为了研究状 (CP) 形态学,特别是CP-Volume,作为病理确认的阿尔茨海默病 (AD) 的功能标志物.
- 测试 CP-体积随着AD病理性增加而增加,以弥补减少的清除率的假设.
主要方法:
- 分析了312名患有病理后果的患者的结构T1加权MRI.
- 根据tau和粉样蛋白病理学,患者被分为正常,预AD,轻度AD和严重AD组.
- 双边CP-Volumes被自动细分,规范化,并使用贝叶斯的多级回归分析,控制共变量.
主要成果:
- 在AD组中,与正常对照组相比,观察到CP-Volume更高的高概率 (>0.9).

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...
