Starting beta-blocker treatment within 24 hours of cardiothoracic surgery provides significant recovery benefits according to new research in The Annals of Pharmacotherapy. Beta-blockers shortened hospital stays by 2.2 days and reduced atrial fibrillation, a dangerous heart rhythm, by 17.3%. These important findings were released early at The Annals of Pharmacotherapys Articles Ahead of Print (www.theannals.com) and will appear in the journals December print issue.
In the article entitled, "Impact of Prophylactic Postoperative Beta-Blockade on Post-Cardiothoracic Surgery Length of Stay and Atrial Fibrillation," Craig I. Coleman PharmD, C. Michael White PharmD, and co-researchers at Connecticuts Hartford Hospital report findings from 1660 patients collected over a 4-year period. In the largest trial of its kind to date, all patients received standard care and half also began beta-blocker treatment shortly after surgery.
In addition to reduced hospital stays and atrial fibrillation, early beta-blocker use was also associated with significant reductions in patient death, the risk of fluid in the lungs, and the need for a balloon pump to assist the heart. Those events were reduced by 59%, 55%, and 53%, respectively. There was no difference in the occurrence of post-surgical stroke or heart attack between the two groups.

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.
The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
Transistors based on carbon nanostructures: what sounds like a futuristic dream could be reality in just a few years' time. An international research team working with Empa has now succeeded in producing nanotransistors from graphene ribbons that are only a few atoms wide, as reported in the current issue of the trade journal "Nature Communications."
Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the...
