The main goal of this study was to determine the optimal strategy for a real-time nonlinear contrast mode for small-animal imaging at high frequencies, on a new array-based micro-ultrasound system. Previously reported contrast imaging at frequencies above …

In previous studies we described enzyme(s) from Escherichia coli that transfer two 3-deoxy-D-manno-octulosonate (KDO) residues from two CMP-KDO molecules to a tetraacyldisaccharide-1,4'-bis-phosphate precursor of lipid A, termed lipid IVA (Brozek, K. A., …

Aim: The actual occurrence of spontaneous plaque rupture in mice has been a matter of debate. We report on an in vivo observation of the actual event of possible plaque disruption in a living ApoE-/- mouse. Methods and Results: During live …

BACKGROUND: We aimed to establish a completely noninvasive technique to assess coronary artery atherosclerosis in living mice using proximal to middle left coronary artery (LCA) velocity ratio as assessed with color Doppler echocardiography (CDE). METHODS …

OBJECTIVE: Matrix metalloproteinases (MMPs) degrade extracellular matrix proteins and play important roles in development and tissue repair. They have also been shown to have both protective and pathogenic effects in atherosclerosis, and experimental …

For an accurate estimate of volumetric coronary flow reserve (CFR) using Doppler-assessed flow velocity measurement, it is important to take into consideration potential diameter change during coronary hyperemia. Using ultrasound techniques, left coronary …

Total longitudinal displacement (tLoD) of the common carotid artery can be measured using the ultrasound-based velocity vector imaging (VVI) technique. This study aimed to investigate clinical correlates and the possible predictive value of tLoD for …

In the present study, we have developed and demonstrated a coronary artery imaging protocol in rats using transthoracic high-frequency CDE (colour Doppler echocardiography) to investigate the potential direct effects of exercise on CFVR (coronary flow …

In vivo mouse coronary artery circulation is still largely unknown. We demonstrate here in vivo coronary flow velocity profiles in anesthesized mice using a novel high-resolution ultrasound technique. … … Non-invasive imaging of coronary arteries in …

Objectives: This study was undertaken to determine if ticagrelor augments adenosine-induced coronary blood flow and the sensation of dyspnea in human subjects. Background: Ticagrelor is a P2Y12 receptor antagonist that showed superior clinical benefit …
