Blood Studies for Cardiovascular System I: Cardiac Biomarkers01:20

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...

科学领域:

  • 神经科学是一个神经科学.
  • 听力学 听力学是指听力学.
  • 认知科学 认知科学

背景情况:

  • 语音噪音感知是一种复杂的神经过程,容易受到神经退行.
  • 了解痴呆症候群如何影响语音噪音处理及其神经基础至关重要.
  • 之前的研究还没有清楚地定义这些影响在不同类型的痴呆症.

研究的目的:

  • 研究阿尔茨海默病 (AD) 和初级渐进性失言症 (PPA) 综合征中的语音噪音处理缺陷.
  • 为了确定听力损失和痴呆症中语音噪音感知障碍之间的关系.
  • 为了识别与在噪音中理解语音困难相关的大脑结构.

主要方法:

  • 进行了数字三倍测试,并进行了自适应信号噪声比 (SNR) 调整.
  • 评估了外周听力,一般认知,并进行了基于voxel的形态测量 (VBM) 的体积脑MRI.
  • 包括48名痴呆症患者 (AD,lvPPA,svPPA,nfvPPA) 和22名健康对照.

主要成果:

  • 阿德,lvPPA和nfvPPA组表现出明显更差的语音在噪音中的感知 (更高的SNR值) 比对照组.
  • PPA (lvPPA) 的logopenic变体表现出最明显的损伤.
  • 基于voxel的形态学确定了语音在噪音中的表现的听觉皮质相关物.

结论:

  • 阿尔茨海默病和PPA综合征呈现出不同的语音噪音损伤模式.
  • 这些缺陷反映了与痴呆症综合征有关的潜在听觉大脑功能障碍.
  • 语音噪音测试可以帮助描述影响听觉处理的神经退行过程.
