Chicken hatchlings prefer ambient temperatures lower than their thermoneutral zone
(Comparative Biochemistry And Physiology A-molecular & Integrative Physiology, 2014-10-01) [Artigo]
We investigated whether or not the preferred ambient temperature (Tapref) of the 1-day old chicken hatchling, a precocial neonate with excellent locomotory capacity, clearly identifiable thermogenesis and independence from ...
Role of neurokinin-1 expressing neurons in the locus coeruleus on ventilatory and cardiovascular responses to hypercapnia
(Respiratory Physiology & Neurobiology, 2010-06-30) [Artigo]
We assessed the role of NK-1 receptors (NK1R) expressing neurons in the locus coeruleus (LC) on cardiorespiratory responses to hypercapnia. To this end, we injected substance P-saporin conjugate (SP-SAP) to kill NK-1 ...
Role of central nitric oxide in behavioral thermoregulation of toads during hypoxia
(Physiology & Behavior, 2008-09-03) [Artigo]
Nitric oxide (NO) is thought to play a key role in the development of hypoxia-induced anapyrexia in mammals, acting on the preoptic region of the anterior hypothalamus to activate autonomic heat loss responses. Regarding ...
NK-1 receptors expressing neurons in the Locus coeruleus (LC) play a role in cardiorespiratory response to CO2
(FASEB Journal, 2010-04-01) [Resumo]
Influence of estrous cycle on the ventilatory responses to hypercapnia and hypoxia in rats
(FASEB Journal, 2011-04-01) [Resumo]
Gap junction blockade in the locus coeruleus (LC) decreases the hypercapnic ventilatory response
(FASEB Journal, 2012-04-01) [Resumo]
Thermoregulatory consequences of salt loading in the lizard Pogona vitticeps
(Journal Of Experimental Biology, 2015-04-01) [Artigo]
Previous research has demonstrated that dehydration increases the threshold temperature for panting and decreases the thermal preference of lizards. Conversely, it is unknown whether thermoregulatory responses such as ...
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 ...
Ionotropic but not metabotropic glutamatergic receptors in the Locus Coeruleus modulate the hypercapnic ventilatory response in unanesthetized rats
(FASEB Journal, 2013-04-01) [Resumo]
Role of preoptic opioid receptors in the body temperature reduction during hypoxia
(Brain Research, 2009-08-25) [Artigo]
Evidence indicates that endogenous opioids play a role in body temperature (Tb) regulation in mammals but no data exist about the involvement of the specific opioid receptors, mu, kappa and delta, in the reduction of Tb ...
