Carotid body tumor: a case report and literature review.
Journal of Radiology Case Reports, 2019 The carotid body is the largest collection of paraganglia in the head and neck and is found on the medial aspect of the carotid bifurcation bilaterally. Carotid body tumors are rare neoplasms arising from the chemoreceptor cells of the carotid bulb.

Computational hemodynamics in arteries with the one-dimensional augmented fluid-structure interaction system: viscoelastic parameters estimation and comparison with in-vivo data [PDF]
J. Biomech. 100 (2020) 109595, 2019 Mathematical models are widely recognized as a valuable tool for cardiovascular diagnosis and the study of circulatory diseases, especially to obtain data that require otherwise invasive measurements. To correctly simulate body hemodynamics, the viscoelastic properties of vessel walls are a key aspect to be taken into account as they play an essential ...

Asian Cardiovascular and Thoracic Annals, 2002 Carotid body paragangliomas were diagnosed by Doppler ultrasound, carotid artery angiography, and cranial computed tomography in a 35-year-old man with a mass in the neck and hearing loss, and in a 42-year-old man with headache, syncope, and a mass in the neck. They underwent successful surgical excision.

The human carotid body in sensing and signaling of oxygen and inflammation [PDF]
, 2014 Oxygen is essential for cell survival and global oxygenation is closely monitored in order to protect tissues from hypoxic damage. The carotid body is an important systemic oxygen sensor responding to hypoxia and a multitude of other blood borne stimuli,

Area-preserving mapping of 3D ultrasound carotid artery images using density-equalizing reference map [PDF]
IEEE Transactions on Biomedical Engineering, 67(9), 1507-1517
(2020), 2018 Carotid atherosclerosis is a focal disease at the bifurcations of the carotid artery. To quantitatively monitor the local changes in the vessel-wall-plus-plaque thickness (VWT) and compare the VWT distributions for different patients or for the same patients at different ultrasound scanning sessions, a mapping technique is required to adjust for the ...

Analysis of the Effect of Atherosclerosis with the Changes of Hematocrit: A Computational Study on the Hemodynamics of Carotid Artery [PDF]
2020 2nd International Conference on Advanced Information and
Communication Technology (ICAICT) (pp. 336-341). IEEE, 2021 Atherosclerosis is a state wherein plaque (fat, cholesterol, and different substances) develops inside the veins that in the end prompts carotid artery stenosis which is a phase of narrowing in the huge courses situated on either side of the neck that convey blood to the brain, face, and head.

Pathogenic Roles of the Carotid Body Inflammation in Sleep Apnea
Mediators of Inflammation, 2014 Breathing difficulties in sleep are a hallmark of sleep-disordered breathing commonly observed in patients with sleep disorders. The pathophysiology of sleep apnea is in part due to an augmented activity of the carotid body chemoreflex.

Tissue-specific mitochondrial HIGD1C promotes oxygen sensitivity in carotid body chemoreceptors
eLife, 2022 Mammalian carotid body arterial chemoreceptors function as an early warning system for hypoxia, triggering acute life-saving arousal and cardiorespiratory reflexes. To serve this role, carotid body glomus cells are highly sensitive to decreases in oxygen

Stratification of carotid atheromatous plaque using interpretable deep learning methods on B-mode ultrasound images [PDF]
, 2022 Carotid atherosclerosis is the major cause of ischemic stroke resulting in significant rates of mortality and disability annually. Early diagnosis of such cases is of great importance, since it enables clinicians to apply a more effective treatment strategy. This paper introduces an interpretable classification approach of carotid ultrasound images for

Nature Communications, 2018 Asthma accounts for 380,000 deaths a year. Carotid body denervation has been shown to have a profound effect on airway hyper-responsiveness in animal models but a mechanistic explanation is lacking.
