Influence of estrous cycle on the ventilatory responses to hypercapnia and hypoxia in rats
(FASEB Journal, 2011-04-01) [Resumo]
Participation of locus coeruleus in breathing control in female rats
(Respiratory Physiology and Neurobiology, 2017-11-01) [Artigo]
Several evidences indicate that the locus coeruleus (LC) is involved in central chemoreception responding to CO2/pH and displaying a high percentage of chemosensitive neurons (>80%). However, there are no studies about the ...
Orexin in the toad Rhinella schneideri: The location of orexinergic neurons and the role of orexin in ventilatory responses to hypercarbia and hypoxia
(Respiratory Physiology & Neurobiology, 2014-11-27) [Artigo]
Recent reports have suggested that orexins, also known as hypocretins, play an important role in the modulation of respiratory control in mammals, but there are no data available describing the role of the orexinergic ...
Hypoxic and hypercapnic ventilatory responses in rats with polycystic ovaries
(Respiratory Physiology & Neurobiology, 2015) [Artigo]
In female rats, a single injection of estradiol valerate (EV) results in effects that are similar to those observed in women with polycystic ovary syndrome (PCOS). We hypothesized that EV-induced PCOS affects breathing ...
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 ...
Temperature effects on baroreflex control of heart rate in the toad, Rhinella schneideri
(Comparative Biochemistry and Physiology. Part A, Molecular & Integrative Physiology, 2015) [Artigo]
For an adequate blood supply to support metabolic demands, vertebrates regulate blood pressure to maintain sufficient perfusion to avoid ischemia and other tissue damage like edema. Using a pharmacological approach ...
Ventilatory, metabolic, and thermal responses to hypercapnia in female rats: effects of estrous cycle, ovariectomy, and hormonal replacement
(Journal Of Applied Physiology, 2015-07-01) [Artigo]
The aim of this study was to examine how estrous cycle, ovariectomy, and hormonal replacement affect the respiratory [ventilation ((V)over dotE), tidal volume, and respiratory frequency], metabolic ((V)over dotO(2)), and ...
ATP in the lateral hypothalamus/perifornical area enhances the CO2 chemoreflex control of breathing
(Experimental Physiology, 2018-12-01) [Artigo]
New Findings: What is the central question of this study? ATP is known to modulate the chemosensitivity of some brain areas. However, whether the ATP contributes specifically to the mechanism of chemoreception in the lateral ...
Hypercapnic and Hypoxic Respiratory Response during Wakefulness and Sleep in a Streptozotocin Model of Alzheimer's Disease in Rats
(Journal of Alzheimer's Disease, 2018-01-01) [Artigo]
Besides the typical cognitive decline, patients with Alzheimer's disease (AD) develop disorders of the respiratory system, such as sleep apnea, shortness of breath, and arrhythmias. These symptoms are aggravated with the ...
