概括
肥胖 (高BMI) 与心力衰竭有关. 虽然更高的BMI增加了左心室壁应力 (LVWS),但它与性尿素相反. 在没有心力衰竭的个体中,LVWS部分解释了这种BMI-尿素关系.
科学领域:
- 心脏病学 心脏病学
- 生物医学工程 生物医学工程
- 公共卫生 公共卫生
背景情况:
- 肥胖是心力衰竭 (HF) 的重要危险因素.
- 尿性 (NP) 是由于左心室 (LV) 壁应力 (WS) 而释放的心脏保护性激素.
- 身体质量指数 (BMI) 和NP水平之间存在一种矛盾的反向关系,表明对它们与WS的关联的理解不完全,特别是在没有HF的个体中.
研究的目的:
- 调查左心室壁应力 (WS) 是否部分调解人体质量指数 (BMI) 和尿素 (NP) 水平之间的关系.
- 在没有明显的心力衰竭的情况下,探索肥胖,心脏压力和荷尔蒙反应之间的复杂相互作用.
主要方法:
- 分析了4444名没有HF的社区动脉样硬化风险研究参与者的数据.
- 通过胸腔回声心脏成像来评估LV终端-透气和终端-静脉压力 (DWS,SWS).
- 进行了调解分析,调整了各种人口,临床和心声学因素.
主要成果:
- 体重指数显示与N-终端亲B型性尿素 (NT-proBNP) 水平的反向关联.
- 体重指数与DWS正相关,但与SWS无关.
- DWS和SWS都与NT-proBNP有积极的关联.
- DWS部分调解了BMI和NT-proBNP之间的反向关系,而SWS没有.
结论:
- 在没有HF的老年人中,增加的BMI与更高的DWS有关.
- DWS与NT-proBNP水平有积极的关系.
- 左心室壁应力 (特别是DWS) 部分解释了BMI和NT-proBNP之间的反向关联,但并不能完全解释它.

Reduced Mass Coordinates: Isolated Two-body Problem
2.4K
In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...

Plant Cell Wall

The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

Responses to Heat and Cold Stress
14.7K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Atomic Mass
69.8K
Atoms — and the protons, neutrons, and electrons that compose them — are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g. When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which...

Bacterial Cell Wall
2.3K
The bacterial cell wall is an essential structural component that encases the plasma membrane, preserving cellular integrity, determining shape, and protecting against osmotic stress. This rigid yet flexible structure primarily comprises peptidoglycan, a polymer that forms a mesh-like matrix conferring mechanical strength and flexibility.Peptidoglycan Composition and StructurePeptidoglycan, the core of the bacterial cell wall, comprises alternating units of N-acetylglucosamine (NAG) and...

Composite Masonry Walls
1.7K
Composite masonry walls combine multiple wythes of the same or different masonry materials to create a unified structure. These walls feature wythes that are bonded together either through mortar-filled collar joints, grouted spaces, or more commonly, with rigid metal ties and reinforcements, with the use of masonry header units being rare. Metal ties are preferred because they effectively minimize water penetration, as these walls primarily absorb moisture and then release it into the...
