Chemical and electric transmission in the carotid body chemoreceptor complex

open access: yesBiological Research, 2005
Carotid body chemoreceptors are complex secondary receptors. There are chemical and electric connections between glomus cells (GC/GC) and between glomus cells and carotid nerve endings (GC/NE).

Evolution of the hypoxia-sensitive cells involved in amniote respiratory reflexes

open access: yeseLife, 2017
The evolutionary origins of the hypoxia-sensitive cells that trigger amniote respiratory reflexes – carotid body glomus cells, and ‘pulmonary neuroendocrine cells’ (PNECs) - are obscure.

Jugular Foramen's Paraganglioma in a Patient with Von Hippel-Lindau Disease: Case Report

open access: yesBrazilian Neurosurgery, 2021
Glomus jugular tumors, also known as paragangliomas (PGLs), are rare and related to several clinical syndromes described. These are located in the carotid body, the jugular glomus, the tympanic glomus and the vagal glomus.

Role of reactive oxygen species in mediating peripheral hypoxic vasodilation and sympathoexcitation at high altitude

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude acclimatisation increases muscle sympathetic nerve activity (MSNA) via activation of the arterial chemoreflex, pulmonary arterial baroreceptors and resetting of the sympathetic vascular baroreflex. However attempting to silence these mechanisms only partially normalises MSNA, implicating other contributory ...

S-Nitrosoglutathione reduces asymptomatic embolization after carotid angioplasty [PDF]

open access: yes, 2002
Background: The major complication of carotid angioplasty is embolic stroke, which may occur after balloon inflation and deflation or in the early postintervention period.

The influence of metaboreflex activation on pulmonary pressure with combined chemoreflex activation in acute and chronic hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Activation of both the metaboreflex via post‐exercise circulatory occlusion and the chemoreflex via acute and chronic hypoxia increased pulmonary artery systolic pressure. Coactivation of these reflexes further increased pulmonary artery pressure in an additive manner.

Reconstruction and quantification of the carotid artery bifurcation from 3D ultrasound images [PDF]

open access: yes, 2004
Three-dimensional (3-D) ultrasound is a relatively new technique, which is well suited to imaging superficial blood vessels, and potentially provides a useful, noninvasive method for generating anatomically realistic 3-D models of the peripheral ...

Multifocal Paraganglioma Including the Cervical Sympathetic Chain

open access: yesEar, Nose & Throat Journal
Multifocal head and neck paragangliomas are exceptionally rare. We present a patient with 4 synchronous tumors including a sympathetic chain lesion. This is a case report and literature review conducted from September 2021 to the present. Our 69-year-old

Hypoxia‐induced vulnerability of the somatosensory nervous system

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Sensory neurons are highly energy dependent and rely on sufficient oxygen availability to maintain metabolic stability and effective neurocommunication. Within the somatosensory system, even modest reductions in tissue oxygen tension impair neuronal respiration, forcing a shift toward less efficient metabolic pathways that ...

Results of surgical resection of carotid body tumors: A twenty-year experience

open access: yesRare Tumors, 2020
This study examines whether surgical resection of carotid body tumors (CBTs) is acceptable in light of potential significant neurologic complications. This IRB-approved retrospective study analyzed data from 24 patients undergoing surgical treatment for ...
