Scientific Reports, 2023 In a longitudinal design, four arterial segments in mice were followed by positron emission tomography/computed tomography (PET/CT) imaging. We aimed to determine how the tracers reflected the development of atherosclerosis via the uptake of 2-deoxy-2 ...

Targeting interleukin-1β protects from aortic aneurysms induced by disrupted transforming growth factor β signaling [PDF]
, 2017 Aortic aneurysms are life-threatening conditions with effective treatments mainly limited to emergency surgery or trans-arterial endovascular stent grafts, thus calling for the identification of specific molecular targets.

Helical flow in tortuous aortas and its relationship to turbulence: A whole-aorta 4D flow MRI study
Frontiers in Cardiovascular Medicine, 2023 BackgroundIncreased vascular tortuosity is a hallmark of ageing of the vascular system, including the aorta. However, the impact of tortuosity on aortic blood flow is unknown.

Evolution of the wall shear stresses during the progressive enlargement of symmetric abdominal aortic aneurysms. [PDF]
, 2006 The changes in the evolution of the spatial and temporal distribution of the wall shear stresses (WSS) and gradients of wall shear stresses (GWSS) at different stages of the enlargement of an abdominal aortic aneurysm (AAA) are important in understanding

TGFβ (transforming growth factor-β) blockade induces a human-like disease in a nondissecting mouse model of abdominal aortic aneurysm [PDF]
, 2017 Objective-Current experimental models of abdominal aortic aneurysm (AAA) do not accurately reproduce the major features of human AAA. We hypothesized that blockade of TGF beta (transforming growth factor-beta) activity-a guardian of vascular integrity ...

Does Orally-Administered Radiocontrast Impair Ultrasound Image Quality in Pediatric Patients? [PDF]
, 2020 Introduction: It is commonly assumed that orally-administered radiocontrast material (ORC) preceding abdominal ultrasound (US) performance can obscure image quality and potentially impair diagnostic accuracy when assessing patients with abdominal pain ...

A possible new approach in the prediction of late gestational hypertension: The role of the fetal aortic intima-media thickness [PDF]
, 2017 The aim was to determine the predictive role of combined screening for late-onset gestational hypertension by fetal ultrasound measurements, third trimester uterine arteries (UtAs) Doppler imaging, and maternal history.

Associations of Perirenal Fat Thickness with Renal and Systemic Calcified Atherosclerosis. [PDF]
, 2020 BackgroundWe investigated associations between perirenal fat thickness and atherosclerotic calcification in six different vascular beds.MethodsUsing a community-based cohort (n=3,919), perirenal fat thickness was estimated from computed tomography scans.
