概括
患有肥胖和低肝脂肪的年轻人显示FGF21增加,这是早期代谢压力的标志物. 这表明纤维细胞生长因子-21 (FGF21) 可能在代谢功能障碍相关的脂肪性肝病 (MASLD) 发生之前预测肝脏代谢问题.
科学领域:
- 儿科内分泌学 儿科内分泌学
- 肝病学 肝病学是一种肝病学.
- 代谢综合征研究 代谢综合征研究
背景情况:
- 肥胖的年轻人容易产生肝脏脂肪积累,甚至低于代谢功能障碍相关的脂肪性肝病 (MASLD) 的门.
- 低于值的肝脂肪可能表明代谢风险,但纤维细胞生长因子-21 (FGF21) 在这种情况下的作用尚不清楚.
研究的目的:
- 为了研究肝脏脂肪低于5%和青春期青少年肥胖的代谢标志物之间的关联.
- 具体研究FGF21在这个群体中的作用.
主要方法:
- 对58名肥胖和肝脂肪<5%的青春期青少年进行横截面分析 (MRI-PDFF).
- 测量了禁食葡萄糖,胰岛素,脂质,瘦素,氨酸和FGF21.
- 使用HOMA-IR评估胰岛素敏感性,并分析了与PDFF的关联,并对共变量进行调整.
主要成果:
- PDFF与BMI SDS,腰围,葡萄糖,TG/HDL-C比率和FGF21正相关.
- 调整后的模型显示PDFF与较高的FGF21独立相关 (p=0.02).
- 没有发现PDFF与HOMA-IR,素或脂蛋白之间的显著关联.
结论:
- 在患有肥胖和MASLD前肝脂肪的青少年中,增加PDFF与FGF21升高有关.
- FGF21可能作为早期肝脏代谢应激的生物标志物,在明显的MASLD之前.
- 这些发现凸显了FGF21在"MASLD前"状态中识别有风险的年轻人的潜力.

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

Obesity
1.4K
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...

Elevation of Intermediate Points on Vertical Curves
308
Vertical curves are essential in roadway design because they provide smooth transitions between varying roadway grades. Designing vertical curves involves calculating intermediate elevations and identifying the curve's highest or lowest point, which is essential for optimal roadway performance.Intermediate elevations on a vertical curve are determined using the tangent offset method. This method considers the initial elevation at the start of the curve, the grades, and the curve's geometry. The...

Drug Dosing: Obese Patients
269
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

Fats as Energy Storage Molecules
27.1K
Triglycerides are a form of long-term energy storage molecules. They are made of glycerol and three fatty acids. To obtain energy from fat, triglycerides must first be broken down by hydrolysis into their two principal components, fatty acids and glycerol. This process, called lipolysis, takes place in the cytoplasm. The resulting fatty acids are oxidized by β-oxidation into acetyl-CoA, which is used by the Krebs cycle. The glycerol that is released from triglycerides after lipolysis...

Liver Histology

The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
