A new analysis of adjuvant radiation therapy in women with breast cancer following mastectomy is associated with better survival as measured at 10 years when appropriate doses and fields of radiation are used. The study was published in the January 4 issue of the Journal of the National Cancer Institute . The finding helps resolve controversy over whether radiation therapy improves both survival and risk of recurrence in women with operable breast cancer.
Past studies of radiation therapy in women with operable breast cancer have led to the conclusion that radiation therapy reduces the risk of recurrence of breast cancer but the effects on overall survival have been less clear. However, in some clinical trials, radiation therapy was given in inadequate or excessive doses or did not target an appropriate amount of tissue, including the chest wall and lymph nodes.
Val Gebski, of the National Health and Medical Research Council Clinical Trials Centre in New South Wales, Australia, and colleagues reanalyzed results from 36 clinical trials in which the use of radiation therapy was the sole difference between treatments given to breast cancer patients. They divided trials into three categories: category 1, for studies that used optimal radiation doses delivered to an appropriate amount of tissue; category 2, for studies where patients received an inadequate or excessive dose of radiation; and category 3, for studies in which an inadequate amount of tissue was treated with radiation therapy.

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...
