A test that generally is used to measure the amount of vitamin B12 in the body is not sensitive enough to detect a deficiency of the vitamin, which has been linked to several neurological conditions, according to Saint Louis University research. The findings were presented this month at a meeting of the American Neurological Association.
"B12 deficiency is associated with dementia, peripheral neuropathy and spinal cord disease," says Florian Thomas, M.D., Ph.D., associate professor of neurology at Saint Louis University School of Medicine and a researcher on the project. "While it occurs at any age, B12 deficiency is more common in the elderly, may affect some vegetarians and their newborns, can be provoked by laughing gas anesthesia and also by a unique form of recreational drug use. Importantly, it is very easy to treat by taking one pill per day for life. We need to do a better job of detecting the problem."
Thomas and his Saint Louis University colleagues, Laurence J. Kinsella, M.D., associate professor of neurology, and Jamie T. Haas, M.D., a neurology resident, found that the standard test for B12 deficiency -- measuring its blood level -- may be too insensitive.

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...
