Age and gender effects on echocardiographic and histopathological cardiac phenotypes in healthy adult mice

Animal Models and Experimental Medicine, EarlyView.
This study investigated the impact of age and sex on cardiac phenotypes in healthy adult C57BL/6J mice using echocardiography and histopathological analyses. Findings revealed that female mice demonstrated more pronounced global cardiac chamber dilation during aging.

Eruptions from solar ephemeral regions as an extension of the size distribution of coronal mass ejections

, 2009
Observations of the quiet solar corona in the 171A (~1MK) passband of the Transition Region and Coronal Explorer (TRACE) often show disruptions of the coronal part of small-scale ephemeral bipolar regions that resemble the phenomena associated with ...

Left Ventricular Outflow Tract Geometry as a Predictor of Permanent Pacemaker Implantation After Transcatheter Aortic Valve Implantation Using the Evolut Series

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Predicting the need for permanent pacemaker implantation (PPM) after transcatheter aortic valve implantation (TAVI) is crucial for procedural planning and patient counseling. Aims To evaluate whether left ventricular outflow tract (LVOT) morphology, specifically a tapered configuration, predicts conduction disturbances requiring PPM

MHD simulations of accretion onto a dipolar magnetosphere. II. Magnetospheric ejections and stellar spin-down [PDF]

, 2012
This paper examines the outflows associated with the interaction of a stellar magnetosphere with an accretion disk. In particular, we investigate the magnetospheric ejections (MEs) due to the expansion and reconnection of the field lines connecting the ...

A Machine Learning Approach for Identifying Coronal Mass Ejection–associated Stellar Flares in TESS Observations

The Astrophysical Journal Supplement Series
Coronal mass ejections (CMEs) are major drivers of stellar space weather and can strongly influence the habitability of exoplanets. However, compared to the frequent occurrence of white-light flares, confirmed stellar CMEs remain extremely rare.
