Journal of Small Animal Practice, EarlyView.Objectives Gastroesophageal reflux during anaesthesia is a common event occurring in dogs with the potential to cause oesophageal injury and aspiration pneumonia. The objective of the current study was to evaluate the effect of the novel metabotropic glutamate receptor 5 antagonist TT001 on gastroesophageal reflux during anaesthesia in dogs using two ...

PULMONARY CHEMORECEPTORS [PDF]
Quarterly Journal of Experimental Physiology and Cognate Medical Sciences, 1963 The existence of a chemoreceptor mechanism supplied by the pulmonary artery was demonstrated in the following manner.In anæsthetized cats or rabbits the main pulmonary artery was cannulated through the right ventricle. The right pulmonary artery was tied and the left pulmonary artery cannulated approximately 0·5 cm. from the bifurcation.

Experimental Physiology, EarlyView.Abstract Acute low oxygen exposure (hypoxia) elicits a hypoxic ventilatory response (HVR), which increases ventilation and mitigates hypoxaemia. During sustained exposure to hypoxia, ventilatory acclimatization increases peripheral chemoreflex (HVR) sensitivity or chemoreflex loop gain (LG).

Experimental Physiology, EarlyView.Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Rotenone selectively occludes sensitivity to hypoxia in rat carotid body glomus cells [PDF]
, 2003 Carotid body glomus cells release transmitters in response to hypoxia due to the increase of excitability resulting from inhibition of O2 -regulated K+ channels. However, the mechanisms involved in the detection of changes of O2 tension are unknown.

Nitric oxide and carotid body chemoreception
Biological Research, 2001 Nitric oxide (NO) has been proposed as an inhibitory modulator of carotid body chemosensory responses to hypoxia. It is believed that NO modulates carotid chemoreception by several mechanisms, which include the control of carotid body vascular tone and ...

Frontiers in Physiology, 2018 Exposure to chronic sustained hypoxia (SH), as experienced in high altitudes, elicits an increase in ventilation, named ventilatory acclimatization to hypoxia (VAH).

Experimental Physiology, EarlyView.Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...

The effect of combined glutamate receptor blockade in the NTS on the hypoxic ventilatory response in awake rats differs from the effect of individual glutamate receptor blockade. [PDF]
, 2014 Ventilatory acclimatization to hypoxia (VAH) increases the hypoxic ventilatory response (HVR) and causes persistent hyperventilation when normoxia is restored, which is consistent with the occurrence of synaptic plasticity in acclimatized animals ...
