- 发现生物标志物的发现.
背景情况:
- 参与胎儿肺部发育,组织重塑和氧化应激的蛋白质可能会影响婴儿肺功能.
- 了解这些蛋白质关联可以为早期识别呼吸风险提供信息.
研究的目的:
- 调查带血蛋白质概况与健康婴儿肺功能和呼吸系统症状之间的关联.
- 为早期呼吸系统健康评估确定潜在的蛋白质生物标志物.
主要方法:
- 在369名健康婴儿中对9种带血蛋白 (生长因子,金属蛋白酶,自标志物) 进行分层分类.
- 线性和负双项回归分析,以评估蛋白质配置文件与肺功能 (tPTEF/tE) 和呼吸系统症状的关联.
主要成果:
- 确定了四种不同的蛋白质概况:高生长因子,平衡,低VEGF-A,低生长因子/金属蛋白酶/自标志物.
- 较低的VEGF-A概况显示了一种趋势,即缩短了到峰值呼气流到呼气时间 (tPTEF/tE) 的时间.

01:05Breathing
65.9K
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...

4.1K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

01:19Factors Affecting Pulmonary Ventilation
3.6K
Besides the pressure difference between the external environment and the lungs, the airflow rate and ease of pulmonary ventilation are also influenced by three other factors: surface tension of the fluid in the alveoli, compliance of the lungs, and airway resistance.
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...
