CT technology shows how blood flow can predict effectiveness of ovarian cancer treatment

Added: 28.06.2017 23:08 | 3 views | 0 comments

Technology can provide a new window into whether or not patients are responding to treatment for advanced ovarian cancer. A multi-center clinical trial has demonstrated that CT Perfusion, which measures blood flow and blood volume to tumors associated with ovarian cancer, can provide an accurate prediction of how well a treatment is working, allowing physicians the opportunity to better plan treatment.

How are long strands of DNA packed into tiny cells?

Added: 28.06.2017 23:08 | 3 views | 0 comments

Scientists are a step closer to understanding how our DNA is squeezed into every cell in the body. They provide the first-ever detailed picture of the nucleosome, the most basic building block of chromosomes (the structures that house our DNA). This finding will inform research on all processes that involve chromosomes, such as gene expression and DNA repair, which are critical to the understanding of diseases such as cancer.

Biofuel from waste: Zeolite catalysts pave the road to decentralized chemical processes

Added: 28.06.2017 22:21 | 4 views | 0 comments

Fuel from waste? It is possible. But hitherto, converting organic waste to fuel has not been economically viable. Excessively high temperatures and too much energy are required. Using a novel catalyst concept, researchers have now managed to significantly reduce the temperature and energy requirements of a key step in the chemical process. The trick: the reaction takes place in very confined spaces inside zeolite crystals.
