Mu and kappa opioid receptors of the periaqueductal gray stimulate and inhibit thermogenesis, respectively, during psychological stress in rats
(Pflugers Archiv-european Journal Of Physiology, 2017-09-01) [Artigo]
The periaqueductal gray matter (PAG) is rich in mu and kappa opioid receptors, and this system is involved in thermoregulation, analgesia, and defensive behaviors. No study approached the involvement of the PAG opioids in ...
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 ...
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 ...
Hypoxia during embryonic development increases energy metabolism in normoxic juvenile chicks
(Comparative Biochemistry And Physiology A-molecular & Integrative Physiology, 2017-05-01) [Artigo]
Environmental changes during perinatal development can affect the postnatal life. In this sense, chicken embryos that experience low levels of O-2 over a specific phase of incubation can have their tissue growth reduced ...
