Association between histological diaphragm atrophy and ultrasound diaphragm expiratory thickness in ventilated patients

Journal of Intensive Care, 2022
Background: Diaphragm fiber atrophy has been evidenced after short periods of mechanical ventilation (MV) and related to critical illness-associated diaphragm weakness.

Eventration of the Diaphragm

Asian Journal of Surgery, 2006
Eventration of the diaphragm (ED) is defined as the abnormal elevation of the diaphragm. Although asymptomatic ED may be amenable to conservative treatment, symptomatic ED in children, either congenital or acquired, may require surgical treatment.

PZT-Film-Based Piezoelectric Micromachined Ultrasonic Transducer with I-Shaped Composite Diaphragm

Micromachines, 2022
We proposed a PZT-film-based piezoelectric micromachined ultrasonic transducer (pMUT) with an I-shaped composite diaphragm to improve the sensitivity and resonant frequency of pMUTs with the same diaphragm area. The finite element method (FEM) simulation

Optogenetic activation of the diaphragm

Scientific Reports, 2022
Impaired diaphragm activation is common in many neuromuscular diseases. We hypothesized that expressing photoreceptors in diaphragm myofibers would enable light stimulation to evoke functional diaphragm activity, similar to endogenous bursts.

Effect of Oxidative Stress on Diaphragm Dysfunction and Exercise Intervention in Chronic Obstructive Pulmonary Disease

Frontiers in Physiology, 2021
Chronic obstructive pulmonary disease (COPD) can cause extrapulmonary injury such as diaphragm dysfunction. Oxidative stress is one of the main factors causing diaphragm dysfunction in COPD.

Clinical impact of preoperative diaphragm dysfunction on early outcomes and ventilation function in lung transplant: a single-center retrospective study

Journal of Intensive Care, 2022
Background Clinical impact of preoperative diaphragm dysfunction on lung transplantation has not been studied. We aimed to evaluate how preoperative diaphragm dysfunction affects clinical outcomes and ventilation function after transplantation.

Reversal modeling and optimal design of hyper-elastic diaphragm in space fuel tanks

SN Applied Sciences, 2021
Diaphragm tanks are a common type of pressurized tanks in which the diaphragm is used to separate the fuel part from the high-pressure part, compress the fuel in the tank, and reduce free space to avoid liquid fuel sloshing.
