Journal Highlight: Finding the right balance - a personal journey from individual proteins to membrane-embedded motors

Date: Apr 9, 2012

Author:

The present review, based on the FEBS/EMBO Women in Science Lecture, offers a personal view of the transition from determining the mass of an individual protein to elucidating the structure and dynamics of heterogeneous assemblies in the megadalton mass range.

Cyclic exposure of poultry to drugs: Antimicrobial drugs discovered in feather meal used as food supplement

Date: Apr 1, 2012

Author: Steve Down

Animal feed supplements made from poultry feathers contain antimicrobial drugs which will re-enter the food chain when fed to farm animals, say US researchers, in the first study of its kind.

Getting lacquered: Pyrolysis with lithium attachment mass spectrometry for gentle analysis of Japanese lacquers

Date: Mar 15, 2012

Author: Steve Down

Japanese lacquer films have been examined by pyrolysis followed by lithium ion attachment mass spectrometry, which offers a rapid approach to characterisation that gives notably different results from pyrolysis-GC/MS.

Journal Highlight: Towards a universal LC-MS screening procedure - can an LIT LC-MSn screening approach and reference library be used on a quadrupole-LIT hybrid instrument?

Date: Mar 12, 2012

Author:

The aim of the study was to prove whether a recently developed linear ion trap LC-MSn screening approach and reference library can be transferred to an LC-MS/MS system with a quadrupole-LIT hybrid mass analyzer using SmileMS, a sophisticated search algorithm.

Playing with plastics: Phthalate transfer from toys to children via sweat

Date: Mar 1, 2012

Author: Steve Down

The role of sweat in the migration of one toxic phthalate plasticiser from toys to children has been estimated by Turkish scientists using GC/MS, in the first study of its type.

Parabens and breast cancer: Controversial preservatives found in almost all breast tissues

Date: Feb 15, 2012

Author: Steve Down

The controversy surrounding the link between parabens and breast tissue resurfaced in January with the news that virtually every breast tissue sample from 40 breast cancer patients contained these common preservatives.

Journal Highlight: Wood typification by Venturi easy ambient sonic spray ionization mass spectrometry: the case of the endangered Mahogany tree

Date: Feb 13, 2012

Author:

Venturi easy ambient sonic spray ionization mass spectrometry in both its liquid and solid sample modes is shown to provide nearly immediate and secure typification of woods, as demonstrated for mahogany, an endangered and most valuable type of tropical wood.

Potty about tobacco: Nicotine traces in a Mayan pot confirm its use for storing tobacco

Date: Feb 1, 2012

Author: Steve Down

Nicotine traces have been discovered in a 1300-year-old Mayan flask, providing the first physical evidence of tobacco use by the ancient Mayas and only the second recorded case in which the contents match the hieroglyphics on the outside of the vessel.

Journal Highlight: Applications of mass spectrometry to metabolomics and metabonomics: Detection of biomarkers of aging and of age-related diseases

Date: Jan 16, 2012

Author:

The application of metabolomics to aging research is reviewed for two primary audiences: mass spectrometrists interested in applying their technical knowledge to unanswered questions in the aging field, and gerontologists interested in expanding their knowledge of both mass spectrometry and the most recent advances in aging-related metabolomics.

Expanding doping detection: Screening for carbohydrate-based plasma volume expanders

Date: Jan 15, 2012

Author: Steve Down

The plasma volume expanders mannitol, dextran and hydroxyethyl starch, which are on the WADA prohibited list as masking agents, have been determined in urine by a mass spectrometric method. The procedure has been validated to WADA requirements for accredited laboratories.
