分子生物学和遗传学
生物标志物发现发现

背景情况:

衰老与肌肉骨功能障碍有关,导致老年人的运动能力和身体功能下降.
循环生物标记物,包括microRNAs (miRNAs) 和炎症标记物,正在研究它们反映老龄化人口生理状况的潜力.

研究的目的:

调查循环miRNAs,代谢和炎症生物标志物与住院老年人的步行表现之间的联系.
为了确定潜在的分子机制背后的年龄相关的肌肉骨损伤与流动性相关的.

主要方法:

使用OpenArray®平台对754个循环的miRNA进行了分析,来自活跃 (步行≥1公里) 和不活跃 (步行<100米) 的老年人血样本.
经过验证的miRNAs接受了目标预测和途径丰富分析 (基因本体学,潘瑟19.0).
与骨,肌肉和炎症相关的细胞因子和代谢物使用Luminex和ELISA量化.

主要成果:

与不活跃组相比,四种miRNAs (hsa-let7g-5p,hsa-miR-27a-3p,hsa-miR-361-5p,hsa-miR-574-3p) 在活跃的老年人群中显著上调.
途径分析表明,这些miRNAs在衰老过程中参与肌肉和骨代谢.
在活性组中观察到高水平的gp130和IL-10细胞因子.

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

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...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers

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...
