概括
较厚的周状视网膜神经纤维层厚度 (pRNFLT) 与健康对照和唐氏综合征 (DS) 患者的更好的认知功能有关. 在DS中,小点镜头不透明度 (SDLO) 与改变的pRNFLT有关.
科学领域:
- 眼科医生 眼科 眼科
- 神经学 神经学
- 遗传学 是一个遗传学.
背景情况:
- 患有唐氏综合征 (DS) 的人患阿尔茨海默病 (AD) 的风险明显增加.
- 在DS中早期发现AD风险对于及时干预至关重要.
- 这项研究探讨了DS和健康对照 (HC) 中认知功能的眼睛生物标志物.
研究的目的:
- 为了研究认知功能和眼睛测量之间的关联 (周周斑块视网膜神经纤维层厚度[pRNFLT],整个视网膜厚度[WRT],胸膜厚度[CT],和小点镜头不透明度[SDLO]).
- 为了在患有DS和HC的个体中比较这些关联.
主要方法:
- 光谱域光学一致性断层扫描 (SD-OCT) 用于测量pRNFLT,WRT和CT在15名DS参与者和50名HC中.
- 裂灯摄影对SDLO进行了评估.
- 使用考夫曼简要智力测试2 (KBIT-2) 测量认知能力;多变量线性回归分析了关系.
主要成果:
- 较高的认知分数 (IQ) 与更厚的全局,下鼻和下的pRNFLT有显著的关联.
- 小点镜头不透明度 (SDLO) 与DS参与者中较厚的下和时间pRNFLT以及较薄的鼻上pRNFLT有关.
- 冠状腺厚度 (CT) 显示与DS有积极的关联,但与认知功能或SDLO没有显著的联系.
结论:
- 较厚的PRNFLT与HC和DS个体的更好的认知能力相关.
- 在患有SDLO的DS个体中观察到pRNFLT变化的特定模式.
- pRNFLT成为一种潜在的生物标志物,用于在不同人群中评估认知功能.

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...
