MicroRNA molecule can cause pathological changes in the heart

Cardiac fibrosis involves an increase of connective tissue in the cardiac muscle, causing a loss of function. A team of researchers at the Technical University of Munich (TUM) has now discovered that microRNA 29 (miR-29) ...

Muscles out of the spray can

An artificial heart would be an absolute lifesaver for people with cardiac failure. However, to recreate the complex organ in the laboratory, one would first need to work out how to grow multi-layered, living tissues. Researchers ...

Magnetic cellular Legos for the regenerative medicine of the future

By incorporating magnetic nanoparticles in cells and developing a system using miniaturized magnets, researchers at the Laboratoire Matière et Systèmes Complexes (CNRS/Université Paris Diderot) and collaborators have created ...

Child heart patients treated for rare surgical infection

At least a dozen children who had heart surgery at Children's Hospital New Orleans between late May and July have infected incisions, apparently from contaminated equipment.

A virtual heart to simulate arrhythmia

A group of researchers from MIPT and Ghent University (Belgium) has developed the first realistic model of the complex cardiac microstructure. The researchers hope that the model will elucidate the causes of fibrosis, which ...

Heart muscle disease patients benefit from defibrillator

Some heart disease patients who are treated with cardiac resynchronisation therapy (CRT) would live longer and have fewer hospital admissions if they also received a defibrillator, concludes a team of researchers led by Aston ...

How Gata4 helps mend a broken heart

During a heart attack, blood stops flowing into the heart; starved for oxygen, part of the heart muscle dies. The heart muscle does not regenerate; instead it replaces dead tissue with scars made of cells called fibroblasts ...

Ion treatments for cardiac arrhythmia

Approximately 350,000 patients in Germany suffer from various forms of cardiac arrhythmia. The condition can lead to permanent damage as a result of stroke, or it may cause sudden heart failure. In forms of arrhythmia like ...

How the heart turns into bone

Connective tissue cells in the heart turn into bone-producing cells in response to injury, University of California, Los Angeles scientists report November 17 in Cell Stem Cell. The discovery helps explain why some people ...
