Cervical cancers that take up a lot of blood sugar, or glucose, are more resistant to treatment than those that are less glucose-hungry, according to research at Washington University School of Medicine in St. Louis. The researchers also found that the high glucose-uptake tumors can be identified with PET scans, which are already routinely used to determine tumor size and lymph node involvement in cervical cancer patients.
PET scans monitor the amount of a radioactive glucose tracer absorbed by cells, so the brightness of the image reveals how much glucose a tumor takes up. The results of the research teams analysis indicate that PET scans can be used to better determine prognosis in cervical cancer patients.
"Cervical tumors vary more in their glucose uptake than other kinds of cancer, making glucose uptake a very useful indicator for cervical cancers," says Perry W. Grigsby, M.D., a radiation oncologist with the Siteman Cancer Center at Washington University School of Medicine and Barnes-Jewish Hospital. "We found that the tumors with higher uptake were associated with lower survival rates and lower disease-free survival rates."

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
