Variation and development of the turtle chondrocranium, with a description of the common musk turtle (Sternotherus odoratus, Kinosternidae, Cryptodira, Testudines)

The Anatomical Record, EarlyView., 2023
Abstract Based on histological cross‐sections, the chondrocranium of the common musk turtle (Sternotherus odoratus) was reconstructed, described, and compared with other turtles. It differs from that of other turtle chondrocrania by possessing elongated, slightly dorsally orientated nasal capsules with three dorsolateral foramina, which might be ...

Bilateral non-bifurcating carotid arteries in a patient with recurrent cerebrovascular events

Neurological Research and Practice, 2021
Introduction Among congenital anomalies of the carotid artery circulation, the presence of a non-bifurcating carotid artery is extremely rare. Relevant cases with unilateral non-bifurcating carotid artery have scarcely been described in the literature ...

Neuroanatomical study of the podocnemidid turtle Neochelys arenarum (Pleurodira), from the early Eocene of France

The Anatomical Record, EarlyView., 2023
Abstract Neochelys is an exclusively European Eocene podocnemidid genus belonging to a linage that reached this continent at the early Eocene. The so far available anatomical information about it is relatively abundant, especially considering that of its shell, at least partially preserved for the eight valid species currently considered.

Carotid and Aortic Stiffness in Patients with Heterozygous Familial Hypercholesterolemia. [PDF]

PLoS ONE, 2016
The role of plasma cholesterol in impairing arterial function and elasticity remains unclear. We evaluated arterial stiffness, measured locally in the common carotid artery by high-resolution echo-tracking, and aortic stiffness, using carotid-femoral ...

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 ...

Infrahyoid wandering carotid arteries

Radiology Case Reports, 2020
Knowledge of retropharyngeal carotid arteries in patients is important in order to avoid potential catastrophic injuries. Previous studies demonstrated that carotid arteries can change in position at or near the level of the hyoid bone on serial scans ...

Four Different Carotid Atherosclerotic Behaviors Based on Luminal Stenosis and Plaque Characteristics in Symptomatic Patients: An in Vivo Study

Diagnostics, 2019
Correct stratification of ischemic stroke risk allows for the proper treatment of carotid atherosclerotic disease. We seek to differentiate plaque types based on stenosis level and plaque morphology.

Automatic Diagnosis of Carotid Atherosclerosis Using a Portable Freehand 3D Ultrasound Imaging System [PDF]

arXiv, 2023
The objective of this study is to develop a deep-learning based detection and diagnosis technique for carotid atherosclerosis using a portable freehand 3D ultrasound (US) imaging system. A total of 127 3D carotid artery scans were acquired using a portable 3D US system which consisted of a handheld US scanner and an electromagnetic tracking system. A U-

Preparation of gastrodin‐modified dendrimer‐entrapped gold nanoparticles as a drug delivery system for cerebral ischemia–reperfusion injury

Brain and Behavior, Volume 12, Issue 12, December 2022., 2022
Abstract Objective This study sought to evaluate the feasibility of multifunctional gastrodin (GAS)‐containing nano‐drug carrier system against cerebral ischemia–reperfusion injury (CIRI). Methods The drug‐loaded nanocomposite (Au‐G5.NHAc‐PS/GAS) with certain encapsulation efficiency (EE) was prepared by physical adsorption method using different ...

Histological verification of atherosclerosis due to bends and bifurcations in carotid arteries predicted by hemodynamic model

Jornal Vascular Brasileiro
Background Tortuosity and bifurcations in carotid arteries alter the blood flow, causing atherosclerosis. Objectives The aim of the present study is to analyze the effect of variant vascular anatomy in the cervical region on development of ...
