Hypercapnia-induced active expiration increases in sleep and enhances ventilation in unanaesthetized rats
(Journal of Physiology, 2018-08-01) [Artigo]
Key points: Expiratory muscles (abdominal and thoracic) can be recruited when respiratory drive increases under conditions of increased respiratory demand such as hypercapnia. Studying hypercapnia-induced active expiration ...
Orexinergic system in the locus coeruleus modulates the CO2 ventilatory response
(Pflugers Archiv European Journal of Physiology, 2016-05-01) [Artigo]
The orexins are hypothalamic neuropeptides involved in an array of functions such as regulation of sleep/wake states and chemoreception to CO2/pH. The locus coeruleus (LC) is a chemosensitive site and expresses an extensive ...
Influence of estrous cycle hormonal fluctuations and gonadal hormones on the ventilatory response to hypoxia in female rats
(Pflugers Archiv European Journal of Physiology, 2017-10-01) [Artigo]
Sex hormones may influence many physiological processes. Recently, we demonstrated that hormonal fluctuations of cycling female rats do not affect respiratory parameters during hypercapnia. However, it is still unclear ...
Involvement of Serotonergic Neurons in the Ventilatory Response to Hypercapnia in Birds (Chicken, Gallus gallus)
(Faseb Journal, 2017-04-01) [Resumo]
ROLE OF CENTRAL TRPV4 IN THE ACTIVATION OF HEAT LOSS RESPONSES IN WISTAR RATS
(Faseb Journal, 2016-04-01) [Resumo]
Participation of Locus coeruleus (LC) noradrenergic neurons on breathing in female rats
(FASEB Journal, 2012-04-01) [Resumo]
ATP in the locus coeruleus as a modulator of cardiorespiratory control in unanaesthetized male rats
(Experimental Physiology, 2014-01-01) [Artigo]
Locus coeruleus (LC) noradrenergic neurons are chemosensitive to CO2 and pH in mammals and amphibians and are involved in the CO2-related drive to breathe. Purinergic neuromodulation in the LC is of particular interest ...
Serotonergic neurons in the nucleus raphé obscurus are not involved in the ventilatory and thermoregulatory responses to hypoxia in adult rats
(Respiratory Physiology and Neurobiology, 2013-06-15) [Artigo]
The medullary raphé is an important component of the central respiratory network, playing a key role in CO2 central chemoreception. However, its participation in hypoxic ventilatory responses is less understood. In the ...
Role of brain nitric oxide in the cardiovascular control of bullfrogs
(Comparative Biochemistry and Physiology - A Molecular and Integrative Physiology, 2013-06-01) [Artigo]
The goal of the present study was to determine if nitric oxide (NO) acting on the brain of bullfrog (Lithobates catesbeianus) is involved in arterial pressure and heart rate (HR) control by influencing sympathetic activity. ...
The breathing pattern and the ventilatory response to aquatic and aerial hypoxia and hypercarbia in the frog Pipa carvalhoi
(Comparative Biochemistry and Physiology A-molecular & Integrative Physiology, 2012-07-01) [Artigo]
Anuran amphibians are known to exhibit an intermittent pattern of pulmonary ventilation and to exhibit an increased ventilatory response to hypoxia and hypercarbia. However, only a few species have been studied to date. ...
