Fibroblast growth factor 21 (FGF-21) is an endocrine factor that can be secreted into circulation by the liver. FGF-21 takes part in metabolic actions and is thought to be a promising candidate for the treatment of diabetes. However, the role of FGF-21 in atherosclerosis is unknown. In this study, apoE−/− mice were fed an atherogenic diet for 4 weeks with and without subcutaneous injections of FGF-21...
Intravascular ultrasound (IVUS) elastography is an imaging technique that obtains the local mechanical properties of the artery wall and atherosclerotic plaques through strain measurements using IVUS. Knowledge of these mechanical properties may provide crucial information that can help in estimating plaque composition and its vulnerability. Here, we present a new method to estimate the transverse...
The vascular geometry may play an important role in the development of atherosclerosis by modulating the local hemodynamics and mechanical stresses of the vessel wall. The mouse is now the most popular animal model to study cardiovascular disease. Here, we present a method to characterize the 3-D geometry of mouse aortic arches by casting and light stereo-microscopic imaging. After calibration of...
