Carotid Body AT4 Receptor Expression and its Upregulation in Chronic Hypoxia [PDF]

, 2007
Hypoxia regulates the local expression of angiotensin-generating system in the rat carotid body and the me-tabolite angiotensin IV (Ang IV) may be involved in the modulation of carotid body function.

Single cell transcriptome analysis of mouse carotid body glomus cells

Journal of Physiology, 2016
Carotid body (CB) glomus cells mediate acute oxygen sensing and the initiation of the hypoxic ventilatory response, yet the gene expression profile of these cells is not available. We demonstrate that the single cell RNA‐Seq method is a powerful tool for

Multi-Modal Interaction Control of Ultrasound Scanning Robots with Safe Human Guidance and Contact Recovery [PDF]

arXiv, 2023
Ultrasound scanning robots enable the automatic imaging of a patient's internal organs by maintaining close contact between the ultrasound probe and the patient's body during a scanning procedure. Comprehensive, high-quality ultrasound scans are essential for providing the patient with an accurate diagnosis and effective treatment plan.

Cognitive function in late‐stage HFpEF patients with tricuspid regurgitation undergoing transcatheter tricuspid valve intervention

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1323-1330, December 1, 2022., 2022
Abstract Objectives This study evaluates the impact of transcatheter tricuspid valve interventions (TTVI) on cognitive function (CF), quality of life (QOL), and exercise capacity in late‐stage heart failure with preserved ejection fraction (HFpEF) and relevant tricuspid regurgitation (TR).

Our experience in managing carotid body tumors in tertiary care center

Indian Journal of Vascular and Endovascular Surgery, 2023
Introduction: Carotid body tumors (CBTs), also known as paragangliomas or chemodectomas, are rare neuroendocrine neoplasms that arise near the carotid bifurcation within glomus cells derived from the embryonic neural crest. The reported incidence of CBTs

Carotid body resection for sympathetic modulation in systolic heart failure: results from first‐in‐man study

European Journal of Heart Failure, 2017
Augmented reflex responses from peripheral chemoreceptors, which are mainly localized in the carotid bodies (CBs), characterize patients with systolic heart failure and contribute to adrenergic hyperactivation.

Oxygen sensing by the carotid body: mechanisms and role in adaptation to hypoxia.

American Journal of Physiology - Cell Physiology, 2016
Oxygen (O2) is fundamental for cell and whole-body homeostasis. Our understanding of the adaptive processes that take place in response to a lack of O2(hypoxia) has progressed significantly in recent years.

3-D Registration on Carotid Artery imaging data: MRI for different timesteps [PDF]

2016 38th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2016
A common problem which is faced by the researchers when dealing with arterial carotid imaging data is the registration of the geometrical structures between different imaging modalities or different timesteps. The use of the "Patient Position" DICOM field is not adequate to achieve accurate results due to the fact that the carotid artery is a ...

Orexinergic neurons in the hypothalami of an Asiatic lion, an African lion, and a Southeast African cheetah

Journal of Comparative Neurology, Volume 531, Issue 3, Page 366-389, February 2023., 2023
Photomicrograph of orexinergic neurons forming the main orexinergic neuronal cluster in the hypothalamus of a Southeast African cheetah. While showing the standard features of the orexinergic system, the Southeast African cheetah, along with an Asiatic and an African lion, also exhibits specializations in the organization of this system.

Multiple paragangliomas involving carotid body and vagal region

Formosan Journal of Surgery, 2019
Paragangliomas are rare neuroendocrine tumors also known to occur in the head-and-neck regions and generally involve the carotid body or vagal region. Till date, only a single study has reported the occurrence of paragangliomas involving both the carotid
