Astrocytic contribution to glutamate-related central respiratory chemoreception in vertebrates
(2021-12)
Central respiratory chemoreceptors play a key role in the respiratory homeostasis by sensing CO2 and H+ in brain and activating the respiratory neural network. This ability of specific brain regions to respond to acidosis ...
The Kolliker-Fuse nucleus orchestrates the timing of expiratory abdominal nerve bursting
(Amer Physiological Soc, 2018-02-01)
Coordination of respiratory pump and valve muscle activity is essential for normal breathing. A hallmark respiratory response to hypercapnia and hypoxia is the emergence of active exhalation, characterized by abdominal ...
Expert consensus statements for the management of COVID-19-related acute respiratory failure using a Delphi method
(2021)
Abstract
Background
Coronavirus disease 2019 (COVID-19) pandemic has caused unprecedented pressure on healthcare system globally. Lack of high-quality evidence on the ...
Serotonin and the control of eupneic breathing
(2018-01-01)
The mechanisms responsible for respiratory rhythm and pattern generation are continuously tuned by neuromodulators. Serotonin is a powerful modulator of the respiratory network that regulates synaptic and intrinsic properties ...
Coupling Between Respiratory and Sympathetic Activities as a Novel Mechanism Underpinning Neurogenic Hypertension
(SPRINGER, 2011)
Enhanced sympathetic outflow to the heart and resistance vessels greatly contributes to the onset and maintenance of neurogenic hypertension. There is a consensus that the development of hypertension (clinical and experimental) ...
Glutamatergic and purinergic mechanisms on respiratory modulation in the caudal NTS of awake rats
(ELSEVIER SCIENCE BV, 2008)
In the present study we evaluated the role of ionotropic glutamate receptors and purinergic P2 receptors in the caudal commissural NTS (cNTS) on the modulation of the baseline respiratory frequency (fR), and on the tachypneic ...
Respiratory inductive plethysmography: a comparative study between isovolume maneuver calibration and qualitative diagnostic calibration in healthy volunteers assessed in different positions
(SOC BRASILEIRA PNEUMOLOGIA TISIOLOGIABRASILIA DF, 2013-08-02)
Objective: To compare two methods of respiratory inductive plethysmography (RIP) calibration in three different positions. Methods: We evaluated 28 healthy subjects (18 women and 10 men), with a mean age of 25.4 +/- 3.9 ...
