Journal Highlight: Carbon–sulfur chains: A high-resolution infrared and quantum-chemical study of C3S and SC7S

Date: Sep 4, 2017

Author: spectroscopyNOW

C3S and SC7S, produced by laser ablation of carbon-sulfur targets, have been characterised by IR spectroscopy and quantum mechanical calculations, leading to the first gas-phase spectroscopic detection of the long SC7S cumulenic chain.

Egg albumen: Protein profiles for six poultry species

Date: Sep 1, 2017

Author: Steve Down

The proteomes of egg albumen from six major poultry species have been determined, revealing commonalities and differences which point to evolutionary divergence and could provide nutritional clues for the food industry.

Turtle takeaway: Pollution monitor at the Great Barrier Reef

Date: Sep 1, 2017

Author: Steve Down

A non-specific mass spectrometric screening method has been used to detect pollutants in green sea turtles from the coastal region of the Great Barrier Reef by comparing with free-ranging turtles using a case control protocol.

Journal Highlight: Novel magnetic resonance imaging for assessment of bronchial stenosis in lung transplant recipients

Date: Aug 21, 2017

Author: spectroscopyNOW

MRI using both ultrashort echo time scans and hyperpolarized 129Xe gas can offer structural and functional assessment of bronchial stenosis which occur seen after lung transplantation.

Journal Highlight: Identification of unique proteomic signatures in allergic and non-allergic skin disease

Date: Aug 21, 2017

Author: spectroscopyNOW

Unique proteomic signatures have been identified to distinguish between inflammatory diseases with similar epidermal disruption and overlapping epithelial inflammation.

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.

Exhaled breath: Doping control option

Date: Aug 15, 2017

Author: Steve Down

In a proof-of-concept study, German scientists have shown that exhaled breath can be used as a novel sampling medium by sports testing organisations for doping control, paving the way for another mode of noninvasive testing.

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.

Date rape drug metabolite: NMR reveals evidence next day

Date: Aug 15, 2017

Author: David Bradley

Nuclear magnetic resonance (NMR) spectroscopy can be used to quickly identify a biomarker for the presence of gamma-hydroxybutyric acid (GHB, the so-called "date rape" drug) in a biological sample from a putative victim of crime. Details are reported in the American Chemical Society's journal Analytical Chemistry.

Plasma toughens nanotubes: Computer simulation

Date: Aug 15, 2017

Author: David Bradley

A computer simulation by US scientists reveals how a high-energy plasma can be used to toughen up carbon nanotubes.
