概括
在阿尔茨海默病 (AD) 患者中,感官马振荡减少了白质损失,并保留了髓. 这种治疗可以通过保护白质完整性和髓化来提供临床益处.
科学领域:
- 神经科学是一个神经科学.
- 神经成像是一种神经成像.
- 蛋白质组学是指蛋白质组学.
背景情况:
- 白质体积损失和脱髓化是阿尔茨海默病 (AD) 脑缩的关键特征.
- 在阿尔茨海默氏症中,脱素化可能发生在症状前,在粉样质斑块和神经纤维状结形成之前.
- 感官唤起的马振荡已经显示出减轻AD患者认知衰退和大脑体积损失的潜力.
研究的目的:
- 为了研究传感唤起的马振荡在阿尔茨海默病中保留髓的假设.
- 评估40Hz感官刺激对AD白质完整性和髓化的影响.
主要方法:
- 神经成像 (MRI T1,T1w/T2w比率) 用于评估在接受40Hz主动或虚假感官刺激的阿尔茨海默症参与者中的白质和体体体积和髓化.
- 脑脊液 (CSF) 蛋白质组学分析是在接受Spectris治疗的轻度认知障碍 (MCI) 参与者的样本上进行的,以确定AD相关途径的变化.
主要成果:
- 与假装治疗相比,主动40Hz感官刺激显著降低了白质缩和髓损失,特别是在内区域和体.
- 治疗改变了参与髓化,突触和神经免疫功能以及脂质运输的CSF蛋白质.
- 路径分析表明,对脂蛋白,胆固醇和脂代谢以及酸丁胆生物合成有显著影响.
结论:
- 感官唤起的马振荡有效地减少了白质缩,并保留了AD中的髓含量.
- 该疗法表现出性效应,显著影响与髓化相关的途径.
- Spectris治疗的临床益处可能源于它对白质和髓保存的积极影响.

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...
