Researchers at the University of Minnesota have identified, for the first time, a gene variation associated with systemic lupus erythematosus (SLE), a complex, inflammatory autoimmune disease that affects multiple organs. The gene variation, known as PTPN22, is found in approximately 16 percent (or one in six) of healthy Caucasians in the United States. However, nearly one in four (or 23 percent) lupus patients carry this variant, which has also now been associated with risk for type 1 diabetes and rheumatoid arthritis. The study is published in the September edition of the American Journal of Human Genetics.
"This appears to be a very important gene for lupus," said Timothy W. Behrens, M.D., professor of medicine, Medical School, and principal investigator, "and this is the first time we have identified a variant that predisposes to many different autoimmune diseases. We hope that this discovery will lead to the identification of other genes associated with lupus and other immune disorders." Behrens believes that dozens of genes may be responsible for lupus and that discovering the combination of these genes will be important to developing better diagnosis and treatment of the disease.
In SLE, a persons immune system begins attacking its own tissues. Organs commonly targeted in SLE include the skin, kidneys, joints, lungs, and the central nervous system. The severity of disease and the response to therapy vary widely between patients, said Behrens, and this leads to significant challenges in the diagnosis and management of lupus. "If we know which genes predispose a person to lupus, we may be able to diagnose and treat the disease earlier," he said. "In addition to discovering which combination of genes lead to lupus and other immune diseases, we also hope this information will help us identify new drugs and therapies."

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...
