Patients who undergo coronary artery bypass surgery are prescribed life-saving medications at discharge significantly less frequently than heart attack patients who receive less invasive angioplasty procedures, according to a new analysis by researchers at the Duke Clinical Research Institute.
These findings are important, the researchers said, because the drugs in question -- aspirin, ACE inhibitors, beta blockers and statins -- have been proven effective by multi-center clinical trials to reduce repeat cardiac events and death and therefore incorporated in established guidelines for care of heart attack patients. The researchers said much room exists for improving the usage rates of these life-saving drugs among all heart patients, including those who received angioplasty.
For example, the Duke team found that 65 percent of angioplasty patients received ACE inhibitors -- a class of blood vessel-relaxing drugs -- compared to only 44 percent of bypass patients. The cholesterol-lowering statins were prescribed for 76 percent of angioplasty patients and 62 percent of bypass patients.

For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.

Physicists from the University of Basel have developed a new method to examine the elasticity and binding properties of DNA molecules on a surface at extremely low temperatures. With a combination of cryo-force spectroscopy and computer simulations, they were able to show that DNA molecules behave like a chain of small coil springs. The researchers reported their findings in Nature Communications.
DNA is not only a popular research topic because it contains the blueprint for life – it can also be used to produce tiny components for technical applications.
