Researchers who are now at Georgetown Universitys Lombardi Cancer Center have identified a gene that promotes metastases, the spread of cancer cells through the body. This new understanding of how cancer metastasizes, linking a gene product and migration of cancer cells, may lead to therapies to stop this spread. The results of the study are published in the May 2003 issue of the journal Molecular Biology of the Cell.

Richard G. Pestell, M.D., Ph.D. and his research team have been studying the cyclin D1 gene and the protein it produces for the past decade. Now they have found that by "knocking out" this gene, the migration of cells can be halted. The migration of cancer cells through the body is a major reason why cancer is deadly.
"Patients who do not survive their cancer, often dont die from their primary cancer, usually they die from the spread of the disease through the body. If we can understand what causes the metastasis, then we can pinpoint new targets to block the spread of disease," said Dr. Pestell, director of the Lombardi Cancer Center, chairman of Georgetowns Department of Oncology and Charlotte Gragnani professor of oncology. "Since cancerous -- but not normal epithelial cells -- migrate, therapy targeted to cell migration would be more selective. Killing only migrating cancer cells is thus less toxic, producing fewer side effects, than current chemotherapy which targets dividing cells of all types."

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

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...
