“Our findings will help doctors better predict who will respond best to temozolomide, which has recently been proposed as a new treatment for gliomatosis cerebri,” said Marc Sanson, MD, PhD, with INSERM, the French government health agency, in Paris, France. “Before now, we weren’t sure which factors influenced how well a person with this type of brain tumor would respond to the treatment.”
For the study, 25 people with gliomatosis cerebri underwent genetic testing and received monthly treatments of temozolomide for up to two years.
The study found nearly all of the participants who were missing chromosome 1p and 19q had a higher response rate to temozolomide and lived longer.
“Eighty-eight percent of those people with this genetic signature responded well to temozolomide compared to only 25 percent of those people without the genetic abnormality,” said Sanson. “In addition, those without 1p and 19q survived an average five and half years compared to only 15 months for the group with intact 1p and 19q.
Those missing 1p and 19q also had more months without the tumor further progressing. Therefore, temozolomide is now our first choice of treatment for patients with gliomatosis cerebri, especially when missing chromosomes 1p and 19q.”

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.
In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...
A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.
By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
