Although transplantation is by far the preferred treatment option for patients with end-stage renal disease (ESRD), those with high levels of "anti-donor" antibodies have had little hope of receiving a donated organ. Among the relatively few who have undergone transplantation, rejection rates have been very high.
Because the immune systems of "highly sensitized" individuals initiate a rejection response against the tissue of the majority of the population, these patients typically spend the rest of their lives undergoing kidney dialysis several times a week – a painful, costly process that extends life but usually results in a diminishing quality of life.
Now, a 12-center study, funded in part by the National Institutes of Health and reported in the December 2004 issue of the Journal of the American Society of Nephrology, found that an immune-modulating therapy pioneered for transplant patients at Cedars-Sinai Medical Center reduced high antibody levels and improved transplantation rates. The analysis was based on the experiences of 98 highly sensitized patients who were administered either the medication, called intravenous immunoglobulin (IVIG), or a placebo while awaiting transplantation.

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”.
The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks...

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.
