..., advanced age, smoking, hypertension, heritable predisposition, and atherosclerosis [ 1 ]. Noninvasive ultrasound is often used to detect and monitor aneurysm development [ 4,5,6 ]. Larger aneurysms have an increased risk of rupture, with 5-5.5 cm considered the typical threshold range for surgical...

... in a mouse model of ferric chloride (FeCl 3 )-induced arterial thrombosis and compared the ability of this method to detect thrombosis with that of a conventional imaging method, namely, ultrasound. The mice ( n = 20) were divided equally into the following 4 groups: (1) a normal group, and (2) 3...

... clots were treated with desmoteplase (DSPA; 2 µg/ml). Ultrasound (2 MHz, 0.179 W/cm 2 ) was included in groups C and E. The fibrin mesh structures of the clots were investigated by electron microscopy. Results: For both clot types lysis rates increased significantly for all treatment strategies compared...

...-endothelialization and intimal hyperplasia after vascular injury. Methods: Sprague-Dawley rats were subjected to balloon injury of the left common carotid artery and treated for 4 weeks with exendin-4 or vehicle. Intimal hyperplasia and vessel wall elasticity were monitored noninvasively by high-frequency ultrasound...

... structure, and abdominal aortic wall dynamics in vivo. Methods: Elastin (ELN) transcript levels were quantified by qRT-PCR and blood pressure was measured with a tail cuff system. M-mode ultrasound was used to track pulsatile abdominal aortic wall motion. Aortas were sectioned and stained to determine...

... stress in vivo. In recent years, techniques have been developed to accurately assess velocity profiles in arterioles, using fluorescently labeled particles as flow tracers, and non-invasively in large arteries by means of ultrasound or magnetic resonance imaging. Wall shear rate is derived from...

... in vivo delivery. Methods and Results: We used a fluorescein-labeled decoy to investigate the ultrasound-microbubble-mediated in vivo delivery in normal and injured mouse arteries. We showed that this approach could deliver the decoy into target tissues. In addition, we performed in vivo NF-ĸB decoy...

... and 74 years of age, using a non-invasive ultrasound system. Prior to the study, the reliability of this system was determined in terms of intrasubject variation. Mean wall shear stress was significantly lower in the common femoral artery (0.35 ± 0.18 Pa) than in the superficial femoral artery (0.49...
