Researchers have closed a randomized clinical trial comparing gefitinib (IressaTM) vs. placebo following chemotherapy and radiation for patients with non-small cell lung cancer (NSCLC) that had spread only to nearby tissues or lymph nodes. Review of interim data indicated that gefitinib would not improve survival.
The clinical trial was sponsored by the National Cancer Institute (NCI), part of the National Institutes of Health in Bethesda, Md., and was conducted by a network of researchers led by the Southwest Oncology Group (SWOG), Ann Arbor, Mich. AstraZeneca Pharmaceuticals LP, Wilmington, Del., which manufactures gefitinib, provided the agent for the trial under the Clinical Trials Agreement with NCI for the development of gefitinib. Iressa is a drug that inhibits an enzyme (tyrosine kinase) present in lung cancer cells, as well as other cancers and normal tissues, that appears to be important to the growth of cancer cells.
Based on a review of the limited data available from the Phase III clinical trial, the Data Monitoring Committee overseeing the trial (known as S0023*) recommended the closure, as the trial would not meet its primary endpoint of improved survival. Detailed results from the study will be presented at the American Society of Clinical Oncology Annual Meeting (ASCO) on May 14, 2005.

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...
