Mineralocorticoid receptor antagonists (MRAs) reduce morbidity and mortality in chronic heart failure. Novel nonsteroidal MRAs are currently developed and need to be pharmacologically characterized in comparison to classical steroidal MRAs. A mouse model …

Recent first attempts of in situ ultrasound strain imaging in collateral ligaments encountered a number of challenges and illustrated a clear need for additional studies and more thorough validation of the avail- able strain imaging methods. Therefore, in …

DL-3-n-butylphthalide (NBP) is used in the treatment of ischemic stroke. It was demonstrated NBP also has a cardioprotective effect in acute myocardial infarction (MI) model. However, the chronic effects of NBP on ventricular function, remodeling, and …

We present a voltage-sensitive phase change agent comprising an aqueous emulsion of surfactant-coated liquid perfluorocarbon droplets nested within a negatively charged phospholipid bilayer. The sensitivity to voltage allows, via exposure to an electric …

Current therapies for heart failure vary depending on the root cause and stage of the disease. Acin-Perez et al . studied the molecular link between mitochondrial dysfunction and heart failure, focusing on OMA1, a protease involved in mitochondrial inner …

Objective This study was designed to explore the relationship between gin- senoside Rb1 (Grb1) and high-load heart failure (HF) in rats. Methods The parameters of cardiac systolic function (left ventricular posterior wall thickness (LVPWT), left …

There are indications for elevated CXCL8 levels in abdominal aortic aneurysm disease (AAA). CXCL8 is concurrently involved in neutrophil-mediated inflammation and angiogenesis, two prominent and distinctive characteristics of AAA. As such we considered an …

3D rendered high-resolution ultrasound (greyscale) and color Doppler (orange and blue) image of a subcutaneous tumor showing blood flow. … … Blood flow in …

Heart failure (HF) is the final common pathway of various cardiovascular diseases. Although it is well documented that reduction of cardiac angiogenesis contributes to the progression from adaptive cardiac hypertrophy to HF, the molecular mechanisms …

OBJECTIVES: This pilot study aimed to investigate the feasibility of non-invasively assessing synovial tissue hypoxia in vivo using photoacoustic (PA) imaging in a post-traumatic osteoarthritis model and explore its correlation with OA severity. METHODS: …
