Age and gender influence the cardiorespiratory function and metabolic rate of broiler chicks during normocapnia and hypercapnia
(Respiratory Physiology & Neurobiology, 2014-08-15) [Artigo]
Pulmonary ventilation (V-E), body temperature (Tb), mean arterial pressure (MAP), heart rate (f(H)) and metabolic rate (V-O2) were measured in 10 (d10)- and 21 (d21)-day-old male and female chicks exposed to 7% CO2. Under ...
Serotonergic mechanisms on breathing modulation in the rat locus coeruleus
(Pflugers Archiv: European Journal of Physiology, 2010-02-01) [Artigo]
The locus coeruleus (LC) is a noradrenergic nucleus that plays an important role in the ventilatory response to hypercapnia. This nucleus is densely innervated by serotonergic fibers and contains high density of serotonin ...
Cardiorespiratory effects of gap junction blockade in the locus coeruleus in unanesthetized adult rats
(Respiratory Physiology & Neurobiology, 2014-01-01) [Artigo]
The locus coeruleus (LC) plays an important role in central chemoreception. In young rats (P9 or younger), 85% of LC neurons increase firing rate in response to hypercapnia vs. only about 45% of neurons from rats P10 or ...
Ionotropic glutamatergic receptors in the rostral medullary raphe modulate hypoxia and hypercapnia-induced hyperpnea
(Respiratory Physiology & Neurobiology, 2011-01-31) [Artigo]
It has been suggested that the medullary raphe (MR) plays a key role in the physiological responses to hypoxia and hypercapnia. We assessed the role of ionotropic glutamate receptors in the rostral MR (rMR) in the respiratory ...
