Ultrasound Imaging for Diaphragm Dysfunction: A Narrative Literature Review.
Of the various muscles that make up the respiratory system, the diaphragm is the prima donna. In the past, only specialist research centers were able to estimate and challenge the effort of this muscle; this was achieved by measuring transdiaphragmatic ...

Indices of Defective Autophagy in Whole Muscle and Lysosome Enriched Fractions From Aged D2-mdx Mice
Duchenne muscular dystrophy (DMD) is a fatal, progressive muscle disease caused by the absence of functional dystrophin protein. Previous studies in mdx mice, a common DMD model, identified impaired autophagy with lysosomal insufficiency and impaired ...

Design and Mechanics of Cable-Driven Rolling Diaphragm Transmission for High-Transparency Robotic Motion [PDF]
Applications of rolling diaphragm transmissions for medical and teleoperated robotics are of great interest, due to the low friction of rolling diaphragms combined with the power density and stiffness of hydraulic transmissions. However, the stiffness-enabling pressure preloads can form a tradeoff against bearing loading in some rolling diaphragm ...

Background Diaphragm atrophy and dysfunction are consequences of mechanical ventilation and are determinants of clinical outcomes. We hypothesize that partial preservation of diaphragm function, such as during assisted modes of ventilation, will restore ...

PNEUMATIC COMPENSATOR FOR PLUNGER PUMP WITH SUBMERSIBLE LINEAR DRIVE
The relevance. The authors have developed the design and operation principle of a pneumatic compensator for a plunger pump with a submerged magnetoelectric motor, which allows reducing the amplitude of pressure fluctuations at the pump outlet by ...

Topological charge of optical vortices and their superpositions [PDF]
An optical vortex passed through an arbitrary aperture (with the vortex center found within the aperture) or shifted from the optical axis of an arbitrary axisymmetric carrier beam is shown to conserve the integer topological charge (TC).

Breathing: Motor Control of Diaphragm Muscle.
Breathing occurs without thought but is controlled by a complex neural network with a final output of phrenic motor neurons activating diaphragm muscle fibers (i.e., motor units).
