Acute intermittent hypoxia in neonatal rodent central nervous system facilitates respiratory frequency through the recruitment of hypothalamic areas

Experimental Physiology, EarlyView.
Abstract Moderate and acute intermittent hypoxia (IH) facilitates respiration in adults, mostly by recruiting peripheral chemo‐/baroreceptors. As central chemoreceptors are widely expressed in immature brains, we hypothesized that IH modulates respiration at birth through a purely neurogenic mechanism involving the hypothalamus.

Effects of noradrenaline and phenylephrine on cerebral oxygen saturation during cardiopulmonary bypass in cardiac surgery

Experimental Physiology, EarlyView.
Abstract Cardiopulmonary bypass (CPB) in cardiac surgery is associated with a high risk of postoperative neurological complications. Perioperative use of vasopressors is common to counteract arterial hypotension in this setting. However, use of α‐agonist vasopressors has been associated with cerebral desaturations.

Translating physiology of the arterial chemoreflex into novel therapeutic interventions targeting carotid bodies in cardiometabolic disorders

The Journal of Physiology, EarlyView.
Abstract figure legend The carotid body develops aberrant high activity in chronic heart failure, resistant hypertension, obstructive sleep apnoea (OSA) and diabetes. Hyperactivity of the carotid body leads to both high tonicity and increased sensitivity of the arterial chemoreflex with resultant sympathoexcitation.

Excessive hypercholesterolaemia during pregnancy as a risk factor for endothelial dysfunction in pre‐eclampsia

The Journal of Physiology, EarlyView.
Abstract figure legend Excessive hypercholesterolaemia during pregnancy impairs maternal endothelial function, which, in turn, drives the development of pre‐eclampsia and may also contribute to the increased risk of later‐life cardiovascular disease in women.

Inhibition and potentiation of the exercise pressor reflex by pharmacological modulation of TRPC6 in male rats

The Journal of Physiology, EarlyView.
Abstract figure legend The majority of L4–L5 dorsal root ganglion cells innervating the triceps surae muscles of healthy rats expressed TRPC6 channels. In decerebrated rats, pharmacological inhibition of TRPC6 channels by injection of antagonists (SAR7334 or BI‐749327) into the arterial supply of the triceps surae muscles inhibited the exercise pressor

Revascularization of the External Carotid Artery

Archives of Surgery, 1988
Numerous reports describe the relative effectiveness of external carotid artery (ECA) revascularization in patients with ipsilateral internal carotid artery occlusion. Most, however, suffer from small numbers of patients or lack of detailed follow-up data. In addition, controversy persists regarding the safety with which this procedure can be performed.

External carotid arterial injury

Injury, 2008
Carotid vascular trauma has high mortality. The two primary causes of death are associated head injury and vascular injuries that cause exsanguination or stroke. In the past two decades interventional radiology, i.e. techniques of transcatheter embolisation, has become a vital component of the care of these cases.
