In a retrospective study looking back at a decade of surgeries, Mayo Clinic Cancer Center researchers have determined that surgery to remove metastatic disease from the diaphragm, in conjunction with other procedures to remove the primary diseased tissue in ovarian cancer patients, significantly increases survival rates. Study results were published in Gynecologic Oncology online.
"Surgeons have long believed that removing as much diseased tissue as possible is important for survival of cancer patients," said William Cliby, M.D., associate professor of obstetrics and gynecology at Mayo Clinic. "The choice of many surgeons to not resect diaphragm disease in ovarian cancer patients seemed counterintuitive, but it was based on the feeling that it might not improve survival. We sought to address this issue."
Dr. Cliby’s team cited lack of evidence of survival benefit, concerns over safety (related to complexity and length of the surgery) and lack of surgeon experience as justifications often given for not proceeding with diaphragmatic surgery in advanced ovarian cancer patients. This study provided strong evidence of survival benefit. The five-year survival rates for patients with diaphragm disease who had optimal residual disease (less than 1 cm) was 55 percent for those undergoing diaphragm surgery versus 28 percent for those who did not.

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...
