A new study from the Swedish medical university Karolinska Institutet presents a technique using LC-MS/MS that makes drug testing possible through exhaled air for the first time. By examining people who had received emergency care for an amphetamine overdose, the researchers found that in all cases there were traces of amphetamine and metamphetamine in the exhaled breath.
Scientists from Ruhr-Universität Bochum have used Raman micro-spectroscopy to distinguish, within seconds, healthy fertile and infertile sperm cells. The method has the potential for a novel fertility technology and a test scheme which does not only rely on morphological characteristics, but also utilises chemical signatures.
Coupling an isotope ratio mass spectrometer to an elemental analyser or gas chromatograph/combustion system has been used to analyse squalene and squalane, oils often used in the production of cosmetics and vaccines, and can show whether they came originally from the liver oil of deepwater sharks or from olive oil.
David Wetzel and Yong-Cheng Shi of Kansas State University, USA, and John Reffner from John Jay College, City University of New York, USA have applied microscopic chemical imaging to single modified starch granules. Starch manufacturers can use this to determine if the modifying agent used in the production process is uniformly distributed across individual modified starch granules. Mark Boatwright, a K-State graduate research assistant in grain science and industry assisted with data processing for the study.
The first researchers have arrived on the latest experimental station to become operational at the Diamond Light Source, the UK’s national synchrotron facility. The new experimental station (B18) offers X-ray Absorption Spectroscopy (XAS).
Lipids produced by the aspirin target COX-2 have anti-oxidant and anti-inflammatory properties as presented in a study published online this week in Nature Chemical Biology (doi: 10.1038/nchembio.367).
The location of metal complexes within living cancer cells has been accurately determined using Raman microscopy. The researchers have thus gained new insights into the mechanism of action of metal-containing drugs, to which they ascribe great potential capacities, e.g. in the treatment of cancer. These findings are of fundamental significance and are thus featured as a VIP (very important paper) in the current edition of Angewandte Chemie.
The recipients of the 2010 European Magnetic Resonance Awards are John R. Griffiths (Basic Sciences) for his contributions to the applications of magnetic resonance spectroscopy in oncology, and Stefan Neubauer (Medical Sciences) for his contributions to anatomical and functional cardiovascular magnetic resonance imaging and spectroscopy.
ESA’s Herschel Space Observatory has revealed the chemical fingerprints of potential life-enabling organic molecules in the Orion Nebula, a nearby stellar nursery in our Milky Way galaxy. This detailed spectrum, obtained with the Heterodyne Instrument for the Far Infrared (HIFI) demonstrates the gold mine of information that Herschel-HIFI will provide on how organic molecules form in space.
Researchers Sebastian Busch, Christoph Smuda, Luis Carlos Pardo and Tobias Unruh from the Universitat Politècnica de Catalunya (UPC) have discovered, using neutron spectroscopy techniques, that the molecules of a cell membrane do not move at random as previously believed, but rather in a flowing motion as suggested by various computer simulations.
