Retinopathy of prematurity (ROP) is an eye disease that severely impacts premature infants, especially those born before 31 weeks gestation and those born at very low birth weights (≤1500 g). In this brief review we provide an overview of ...
End-tidal CO2 changes during short breath-hold maneuvers: Variability, paradigm effects, and spirometric correlates [0.03%]
短暂屏气过程中终末呼气二氧化碳的变化：变异性、模式效应和肺通气功能指标的相关性研究

Leonie Zerweck et al.
Breath-hold functional MRI (bh-fMRI) is a widely used method for mapping cerebrovascular reactivity (CVR). Normalization of BOLD signal changes to end-tidal CO₂ changes (ΔpetCO₂) is suggested to improve between-subject comparability. The...
Ventilatory Response to Mechanoreceptor Activation Not Altered in Human Hypertension [0.03%]

The purpose of this study was to determine if the ventilatory responses during mechanically sensitive afferent stimulation were augmented in hypertension (HTN). Participants with HTN (n=11; 52±12yrs; 27±3kg/m2) and controls (CTL, n=11; 56...
Comparing ECG Artifact Removal Methods for Diaphragm EMG during Inspiratory Pressure-Threshold Loading: Effects on Signal Quality and the EMG-Pressure-Time Product Relationship [0.03%]
不同ECG伪迹消除方法对吸气压阈载荷下膈肌EMG的影响：对信号质量和EMG-压力时间乘积关系的影响
Viviana J Shiffman,Jem I Arnold,Chloe A Mathews et al.
Viviana J Shiffman et al.
Diaphragm electromyogram (EMGdi) is commonly measured using esophageal multi-paired electrode catheters; however, contamination by cardiac electrical activity can compromise signal quality. This study compared several approaches for reducin...
Acute modulation of respiratory pressure regulation and abdominal muscle activation during martial arts-derived respiratory-motor training with augmented feedback [0.03%]
基于增强反馈的武术衍生呼吸运动训练中呼吸压力调节和腹肌激活的急性调节

Sherrilyn Walters et al.
Respiratory pressure regulation contributes to trunk stabilisation and force transmission during physically demanding tasks. Traditional martial arts are associated with enhanced respiratory pressure regulation and trunk muscle activation, ...
Hypoxia/Reoxygenation Cycles, Reactive Oxygen Species and Succinate: A Mechanistic Framework for Apnea of Prematurity [0.03%]
早产儿呼吸暂停的机制框架：低氧/复氧循环、活性氧和琥珀酸
Vincent Joseph,Sofia Diego Diaz,Lina Ikhlef et al.
Vincent Joseph et al.
We review clinical observations and experimental data to examine the pathophysiological mechanisms by which apnea of prematurity and intermittent hypoxemia destabilizes respiratory control and might lead to neurodevelopmental disorders. Cli...
Luteolin increases baseline apneas and downregulates brainstem HIF in normoxia and chronic intermittent hypoxia [0.03%]
黄体 flavone 增加正常氧浓度和慢性间歇性缺氧下的基线呼吸暂停并下调脑干 HIF 表达

Bolival Apparecido Mendonça Junior et al.
Hypoxia-inducible factor (HIF) is a key regulator of cellular adaptation to reduced oxygen availability. Chronic intermittent hypoxia (CIH), characterized by recurrent cycles of hypoxia and reoxygenation, promotes oxidative stress and activ...
Contrasting dynamic and peak exercise inspiratory constraints: Implications for dyspnoea and exercise tolerance in chronic obstructive pulmonary disease [0.03%]
慢性阻塞性肺疾病患者吸气限制的动态和峰值运动特征及其对呼吸困难和运动耐力的影响
Pedro Dal Lago,Danilo C Berton,Abed Hijleh et al.
Pedro Dal Lago et al.
Background: Exertional dyspnoea is linked to inspiratory constraints to tidal volume expansion in chronic obstructive pulmonary disease (COPD). Dynamic assessment of these constraints via serial inspiratory capacity (IC) ...
Oral breathing and oxygenation stability during wakefulness: Identifying an unresolved question in respiratory physiology [0.03%]
觉醒状态下的口腔通气与氧合稳定性：呼吸生理学中一个未解决的问题
