克洛托/FGF系统在衰老和代谢健康方面发挥着作用.
肥胖与炎症和肌肉功能障碍有关,模仿衰老的表型.
了解Klotho/FGF系统在肥胖中的作用对于衰老研究至关重要.

研究的目的:

调查Klotho/FGF系统与中年成人炎症和肌肉功能障碍的关联.
探索Klotho,炎症标志物,身体组成和肥胖的肌肉功能之间的关系.
为了确定Klotho/FGF变化是否反映肥胖个体的生物衰老过程.

主要方法:

试点研究包括45名中年成人 (30名肥胖者,15名对照者).
评估PBMC中的Klotho,β-Klotho,FGF19,FGF21,FGF23,TFN-α和IL-10的身体组成,肌肉功能和蛋白质表达.
使用主要组件分析 (PCA) 来分析变量关系.

主要成果:

与对照组相比,肥胖的参与者表现出较低的Klotho和更高的TFN-α水平.
PCA表明更高的Klotho水平与更好的肌肉功能和减少炎症正相关.
克洛托/FGF系统的变化与肥胖的炎症和肌肉功能障碍有关.

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...

Obesity

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...
