概括
在Fontan生理学患者中,乌德纳菲尔改善了呼吸无氧值的运动性能,但没有显著增加峰值氧气消耗. 这项研究突出了这一群体体体能运动能力的潜在益处.
科学领域:
- 心血管医学
- 儿童心脏病学
- 临床药理学
背景情况:
- 丰坦手术创造了一个独特的循环状态 (全腔肺连接),使肺血管阻力放大.
- 随着时间的推移,这种循环会导致心血管效率降低和运动能力下降.
- 缺乏严格的临床试验来改善Fontan患者的生理学和指导药物治疗.
研究的目的:
- 评估乌德纳菲尔在改善Fontan生理功能的有效性.
- 评估乌德纳菲尔对运动中氧气消耗峰值和运动次极值参数的影响.
主要方法:
- 芬坦乌德纳菲尔运动长度 (FUEL) 试验是一项III期临床试验,涉及400名参与者.
- 参与者被随机分配到接受乌德纳菲尔 (87. 5毫克每天两次) 或安慰剂.
- 主要结论是运动高峰时氧气消耗的变化;次要结论包括次最大运动量和生物标志物.
主要成果:
- 与安慰剂相比,乌德纳菲尔治疗没有显著增加峰值氧气消耗 (2. 8% 对比 - 0. 2%,P=0. 071).
- 然而,在通风无氧值的分析显示,乌德纳菲尔显著改善了氧气消耗 (P=0. 012),通风二氧化碳相当量 (P=0. 014) 和工作速度 (P=0. 021).
- 在心肌性能指数,反应性高血压指数或大脑类型酸水平上没有发现显著差异.
结论:
- 在FUEL试验中,乌德纳菲尔治疗 (87. 5毫克每天两次) 并没有改善运动中氧气消耗的峰值.
- 乌德纳菲尔与在呼吸器无氧值的几个运动性能指标的改善有关.
- 进一步的研究可能会探讨乌德纳菲尔在Fontan生理学中增强亚最大运动能力的作用.

Batteries and Fuel Cells
30.6K
A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Combustion Energy: A Measure of Stability in Alkanes and Cycloalkanes
7.6K
The low reactivity in alkanes can be attributed to the non-polar nature of C–C and C–H σ bonds. Alkanes, therefore, were initially termed as “paraffins,” derived from the Latin words: parum, meaning “too little,” and affinis, meaning “affinity.”
Alkanes undergo combustion in the presence of excess oxygen and high-temperature conditions to give carbon dioxide and water. A combustion reaction is the energy source in natural gas, liquified...

Turnover Number and Catalytic Efficiency
19.8K
The turnover number of an enzyme is the maximum number of substrate molecules it can transform per unit time. Turnover numbers for most enzymes range from 1 to 1000 molecules per second. Catalase has the known highest turnover number, capable of converting up to 2.8×106 molecules of hydrogen peroxide into water and oxygen per second. Lysozyme has the lowest known turnover number of half a molecule per second.

Internal Combustion Engine
2.4K
The internal combustion engine is a heat engine that uses the byproducts of combustion as the working fluid instead of using a heat transfer medium to transfer heat. The combustion is done in a way that produces high-pressure combustion products that can be expanded through a turbine or piston to create work. Internal combustion engines can again be categorized into three kinds: (1) spark ignition gasoline engines, most commonly used in automobiles, (2) compression ignition diesel engines that...

Efficiency of The Carnot Cycle
3.5K
The hypothetical Carnot cycle consists of an ideal gas subjected to two isothermal and two adiabatic processes. Since the internal energy of an ideal gas depends only on its temperature, which is the same before and after the completion of the Carnot cycle, there is no change in its internal energy. Hence, using the first law of thermodynamics, the total heat exchanged by the ideal gas equals the total work done. Thus, we can quantify the efficiency of the Carnot cycle via the heat exchanged...

Energy to Drive Translocation
2.6K
Mitochondrial protein import is powered by two distinct energy sources: ATP hydrolysis and electrochemical potential across the inner membrane. Newly synthesized precursors are bound by cytosolic chaperones of the Hsp70 family, which guide them to the import receptors on the mitochondrial surface. Utilizing the energy of ATP hydrolysis, Hsp70 chaperones transfer these precursors to the TOM receptors on the mitochondrial outer membrane.
