Forced expiratory flow‐volume relationships [PDF]

Anaesthesia, 1977
Forced expiratory flow-volume relationships have been used to investigate changes in lung mechanics caused by upper abdominal operations. The slope of the 'effort independent' portion of the flow-volume curve increases after operation, suggesting that restriction of respiratory movement is associated with an increase in lung recoil.

Information Transmission Strategies for Self‐Organized Robotic Aggregation

Advanced Robotics Research, EarlyView.
In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

Postnatal dexamethasone exposure and lung function in adolescents born very prematurely.

PLoS ONE, 2020
We previously demonstrated corticosteroid administration on the neonatal intensive care unit was associated with reduced lung function at 11 to 14 years of age in children born very prematurely.

Gas exchange during exercise in habitually active asthmatic subjects [PDF]

, 2005
We determined the relations among gas exchange, breathing mechanics, and airway inflammation during moderate- to maximum-intensity exercise in asthmatic subjects.

Copper‐Driven Epithelial Barrier Disruption: A Novel Mechanism of COPD Acute Exacerbations Mediated by the TNF‐α/ATP7A Axis

Advanced Science, EarlyView.
This study reveals a copper‐driven mechanism of COPD acute exacerbations mediated by the TNF‐α/ATP7A axis. TNF‐α suppresses the copper transporter ATP7A via competitive NF‐κB/CREB1/CBP signaling, resulting in intracellular copper accumulation, mitochondrial oxidative stress, and epithelial barrier disruption.

Clinical significance of FEV0.5 and FEV0.75 in the determination of pulmonary function in children with bronchial asthma

Shanghai Jiaotong Daxue xuebao. Yixue ban, 2023
Objective·To evaluate the abnormal rates of measured/predicted values of forced expiratory volume in 0.5 second (FEV0.5) and FEV0.75 in lung ventilation function testing, as well as the clinical significance of different cut-off points for improvement ...

Synchronization‐Dissipation in the Cardiorespiratory System

Advanced Science, EarlyView.
By modeling central nervous coupling and viscoelastic interactions in the cardiorespiratory system we show that synchronization produces a 10% gain in cardiac efficiency in humans. It is surmised that respiratory sinus arrhythmia improves cardiac pumping efficiency by reducing dynamic stress and power dissipation in the pulmonary vasculature.

Preoperative Botulinum Toxin A and Its Impact on Pulmonary Function in Giant Abdominal Wall Hernias: A Prospective Spirometry-Based Analysis

Journal of Abdominal Wall Surgery
BackgroundBotulinum toxin type A has become an increasingly used tool in the preoperative management of giant abdominal wall hernias. Its primary objective is to “downstage” the hernia by inducing temporary paralysis of the lateral abdominal wall muscles,
