ESC Congress 2003: Stem cells – A tool for mending broken hearts?
We have shown that stem cell injections by catheters into diseased hearts are feasible and safe, even for very sick patients. Moreover, the results suggested strongly a potential ability of these cells to regenerate the arteries of the heart (called coronary arteries), and this regeneration improved the mechanical function of the heart, improving the heart failure condition of these patients. Since heart failure is a more aggressive killer than most cancers, and the fact that cardiovascular diseases are the leading cause of mortality around the world, this could be a beginning of a “new era” in cardiovascular therapy.
Our study was carried out at Pró-Cardíaco Hospital (granted by the Filantropic Foundation of Teaching and Research of Pró-Cardíaco Hospital - PROCEP), in Rio de Janeiro, with a partnership with the Federal University of Rio de Janeiro and Texas Heart Institute. The experimental models were developed by the Federal University (granted by the Ministry of Science and Technology) and the injection system used to introduce the cells into the heart was developed by Johnson&Johnson, and tested in Houston.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
