研究的目的:
- 调查语音特征与抑郁症的不同维度之间的关系.
- 用声学和基于情感的语言变量来区分抑郁症亚型.
- 评估语音分析在老年人群中客观地表征抑郁症的潜力.
主要方法:

- 采集了语音样本,参与者描述了各种情感主题的图片.
- 自动管道分析了语音特征,与来自老年抑郁症尺度-15 (GDS-15) 的抑郁症维度 (抑郁症,冷漠,绝望,记忆抱怨) 相关联.
主要成果:
- 失调与更高的情绪价值相关,而冷漠与更低的价值相关.
- 漠不关心与低音和较慢的语言有关,特别是与负面刺激.

01:20Blood 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...

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...
