Researchers at Fox Chase Cancer Center in Philadelphia say looking for genes that have been turned off by cancer cells may become a reliable and noninvasive way to detect and monitor cancer in the kidney. The data were presented today at the 96th Annual Meeting of the American Association for Cancer Research in Anaheim, Calif.
Tumor-suppressor genes are part of the bodys natural defense against cancer. When inactivated--or "silenced"--they can no longer do their job, allowing cancer cells to grow. Cancer cells use a mechanism called hypermethylation to turn off the tumor-suppressor genes. "Finding these silenced genes is a good way to find cancer," said Essel A. Dulaimi, M.D., a postdoctoral fellow at Fox Chase. "Abnormal patterns of methylation can be detected in many cancers, including kidney cancer," she added. Early diagnosis of kidney cancer can lead to earlier treatment with a curative outcome.
Dulaimi and fellow Fox Chase researchers used a molecular DNA-based test to determine the presence or absence of methylation in a particular gene. Called methylation-specific polymerase chain reaction (PCR), the test can find one methylated gene among 100 unmethylated alleles (genes at the same site on a specific chromosome).

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.
From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
