Bilateral carotid body tumors: a case report And review [PDF]

, 2018
Carotid body tumors (CBTS) also known as chemodectomas are a type of paragangliomas which originate from the carotid body. Carotid body tumors present as a palpable mass in anterolateral aspect of the neck causing splaying of the external carotid artery (

H2S production by reactive oxygen species in the carotid body triggers hypertension in a rodent model of sleep apnea

Science Signaling, 2016
Suppressing hydrogen sulfide production in the carotid body may prevent the hypertension associated with sleep apnea. Sleeping with lower blood pressure Individuals with sleep apnea periodically stop breathing or breathe more shallowly while sleeping ...

Progress and Application of Multifunctional Hydrogel in Radioactive Skin Injury

Advanced Materials Interfaces, EarlyView.
This review examines healing challenges in radiation‐wound injuries, where ionizing radiation impairs immune and tissue repair processes. Hydrogels, with their biocompatibility, antimicrobial properties, and drug delivery capabilities, present a transformative solution. It compares hydrogel efficacy in radiation‐induced versus common wounds, highlights

Muscarinic receptor localization and function in rabbit carotid body [PDF]

, 1991
Producción CientíficaAcetylcholine and muscarinic agonists inhibit chemosensory activity in the rabbit carotid sinus nerve (CSN). Because the mechanism of this inhibition is poorly understood, we have investigated the kinetics and distribution of ...

Global sensitivity analysis informed model reduction and selection applied to a Valsalva maneuver model [PDF]

, 2020
In this study, we develop a methodology for model reduction and selection informed by global sensitivity analysis (GSA) methods. We apply these techniques to a control model that takes systolic blood pressure and thoracic tissue pressure data as inputs and predicts heart rate in response to the Valsalva maneuver (VM).

Toward “Green” Vessels: Characterization of Microstructure, Mechanics, and Endothelial Cell Interaction on Three Macro‐Tubular Plants for Vascular Tissue Engineering Applications

Advanced Materials Technologies, EarlyView.
The concept of “green” vessels explores naturally derived tubular structures from three decellularized plants—Water Spinach, Green Onion, and Water Horsetail—as innovative alternatives for vessel models and vascular grafts. Microstructural and mechanical testing reveal the promising suturability and mechanical properties of Water Spinach.

Successful Response to Cyclophosphamide, Vincristine, and Dacarbazine Chemotherapy in a Patient with Metastatic Carotid Body Paraganglioma

Case Reports in Oncology, 2021
Carotid body paraganglioma is a rare neuroendocrine tumor presenting with low-grade histological and clinical features. However, the tumor has the potential to produce distant metastasis, and due to its rarity, little information is available regarding ...

Deep Learning-Based Carotid Artery Vessel Wall Segmentation in Black-Blood MRI Using Anatomical Priors [PDF]

arXiv, 2021
Carotid artery vessel wall thickness measurement is an essential step in the monitoring of patients with atherosclerosis. This requires accurate segmentation of the vessel wall, i.e., the region between an artery's lumen and outer wall, in black-blood magnetic resonance (MR) images.

Artesunate Inhibits Neointimal Hyperplasia by Promoting IRF4 Associated Macrophage Polarization

Advanced Science, EarlyView.
This study shows that macrophage interferon regulatory factor 4 (IRF4) improved arterial injury‐induced neointimal hyperplasia by promoting of M2 polarization via up‐regulating krüppel‐like factor 4 (KLF4) in rodent and nonhuman primate models. Notably, artesunate is identified as a potent inducer of IRF4 in macrophages, and proposed as a promising ...
