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

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

Surface Metrology of Cerebral Arteries Luminal Surface [PDF]
arXiv, 2023 Atherosclerotic lesions within carotid and cerebral vessels are likely to influence hemodynamics and manifest into vascular pathologies, including Alzheimers Disease and ischemic stroke. Hemodynamics are influenced by changes in luminal diameter of vessels and wall shear stress derived from turbulence, which directly relates to the surface topography ...

Carotid body: a metabolic sensor implicated in insulin resistance.
Physiological Genomics, 2018 The carotid body is now looked at as a multipurpose sensor for blood gases, blood pH, and several hormones. The matter of glucose sensing by the carotid body has been debated for several years in the literature, and these days there is a consensus that ...

The Carotid Body a Common Denominator for Cardiovascular and Metabolic Dysfunction?
Frontiers in Physiology, 2020 The carotid body is a highly vascularized organ designed to monitor oxygen levels. Reducing oxygen levels in blood results in increased activity of the carotid body cells and reflex increases in sympathetic nerve activity.

Coexistence of a Carotid Body Tumor and Thyroglossal Duct Carcinoma With Cervical Lymph Node Metastasis [PDF]
Clinical and Experimental Otorhinolaryngology, 2014 Thyroglossal duct carcinoma is uncommon, occurring in approximately 1% of all thyroglossal duct remnants. This rare neoplasm is characterized by relatively nonaggressive behavior with infrequent lymph nodal spread.

HIF-2α is essential for carotid body development and function
bioRxiv, 2018 Mammalian adaptation to oxygen flux occurs at many levels, from shifts in cellular metabolism to physiological adaptations facilitated by the sympathetic nervous system and carotid body (CB).
