In vivo metabolic studies in skeletal and cardiac muscle using ¹³C magnetic resonance spectroscopy

Josefina Adriana Maria Bastiaansen

Cardiac and skeletal muscle function relies on a continuous energy production via fatty acid metabolism and mitochondrial oxidation of pyruvate, with a fine balance between substrate delivery and utilization. Changes in metabolism are increasingly being im ...

Embryonic Stem Cell-Based Cardiopatches Improve Cardiac Function in Infarcted Rats

Jeffrey Alan Hubbell

Pluripotent stem cell-seeded cardiopatches hold promise for in situ regeneration of infarcted hearts. Here, we describe a novel cardiopatch based on bone morphogenetic protein 2-primed cardiac-committed mouse embryonic stem cells, embedded into biodegradab ...

Therapeutic Strategies for the Treatment of Atrial Fibrillation : New Insights from Biophysical Modeling and Signal Processing

Laurent Renaud Uldry

Atrial fibrillation is the most common cardiac rhythm disorder encountered in clinical practice, often leading to severe complications such as heart failure and stroke. This arrhythmia, increasing in prevalence with age, already affects several millions of ...

Full Motion and Flow Field Recovery from Echo Doppler Data

Michaël Unser, Michael Sühling, Muthuvel Arigovindan

We present a new computational method for reconstructing a vector velocity field from scattered, pulsed-wave ultrasound Doppler data. The main difficulty is that the Doppler measurements are incomplete, for they do only capture the velocity component along ...

Analysing the potential of Reveal for monitoring cardiac potentials

Aims The implantable loop recorder (ILR) continuously monitors the heart’s electric activity by means of a subcutaneous bipolar electrogram (Elg). Currently, the relationship between the Elg and the surface electrocardiogram (ECG) has been poorly documente ...

Effects of an aging vascular model on healthy and diseased hearts

Nikolaos Stergiopoulos, Rafaela Fernandes Da Silva, David Jegger

The vitamin D(3) and nicotine (VDN) model is a model of isolated systolic hypertension (ISH) due to arterial calcification raising arterial stiffness and vascular impedance similar to an aged and stiffened arterial tree. We therefore analyzed the impact of ...
