Journal Highlight: Graphene-based molecularly imprinted polymer for separation and pre-concentration of trace polycyclic aromatic hydrocarbons in environmental water samples

Date: Aug 29, 2017

Author: separationsNOW

Researchers from South Africa and India used a composite of reduced graphene oxide and pyrene-imprinted polymer for the solid phase extraction of five selected polycyclic aromatic hydrocarbons from water samples.

Journal Highlight: The proteomic profile of a mouse model of proliferative vitreoretinopathy

Date: Aug 29, 2017

Author: separationsNOW

Scientists from Hungary have used 2D gel electrophoresis to help analyze protein changes in a mouse model of proliferative vitreoretinopathy, a complication of retinal detachment surgery that can lead to serious vision loss.

Choose your solvent: For detecting metabolites in colon cancer cells

Date: Aug 22, 2017

Author: Jon Evans

Researchers from Spain and the US have shown that the type of metabolites detected in cancer cells is strongly influenced by the method used to extract them from the cells.

Journal Highlight: Review of HPLC and LC–MS/MS assays for the determination of various nonsteroidal anti-androgens used in the treatment of prostate cancer

Date: Aug 21, 2017

Author: separationsNOW

The literature on bioanalytical methods for the quantification of first- and second-generation nonsteroidal anti-androgens in clinical and preclinical studies has been critically reviewed and some case studies have been presented.

Dominant or submissive: Proteomic clues to behavioural disorders

Date: Aug 15, 2017

Author: Steve Down

The expression of many proteins in the hippocampi of mice are modified by dominant and submissive behaviour, say scientists in Israel in the first study of its kind which will help to decode the molecular mechanisms of psychiatric disorders and lead to therapeutic solutions.

Fast GC’s rapidity gives greater productivity

Date: Aug 15, 2017

Author: Ryan De Vooght-Johnson

GC-MS run times can now be much shorter than with traditional methods due to a number of recent developments. Scientists from Tel Aviv University applied a combination of open probe fast GC and mass spectrometry to obtain rapid results from a wide variety of different analytes.

No standards involved, but are all problems solved?

Date: Aug 15, 2017

Author: Ryan De Vooght-Johnson

Modern analytical techniques, such as HRMS (high-resolution mass spectrometry), enable the simultaneous detection of a large number of compounds, but normally rely on analytical standards of all the compounds being available, which may not be the case. Researchers from the Zurich Official Food Control Authority have developed an LC-HRMS method that identifies compounds without the use of standards, demonstrating its efficiency by identifying veterinary compounds spiked into meat and fish extracts.
