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.

The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
