Various vaping volatiles evaluated by GC/MS

Date: Jan 21, 2020

Author: Ryan De Vooght-Johnson

A variety of aroma compounds are found in e-cigarettes, but little information is available about their prevalence and potential inhalation toxicity. A team of researchers from the University of Innsbruck and the Austrian Drug Screening Institute used GC/MS to quantify the levels of various aroma compounds in commercial e-cigarette liquids, while also looking at the compounds’ effects on human cells.

Sticking with 3D printing: To prevent surface adsorption

Date: Jan 20, 2020

Author: Jon Evans

Researchers have discovered yet another advantage to using 3D printing to fabricate electrophoresis microchips: analytes are less likely to stick to the surfaces of 3D printed chips.

Marine mammal stress proteome: Blubber biomarkers

Date: Jan 16, 2020

Author: Steve Down

The blubber proteome of the elephant seal in response to stress induced by dosing with adrenocorticotropic hormone has been determined by scientists in the US, highlighting proteins that could be used as stress indicators from blubber biopsies.

UHPLC seems right to find sunscreen metabolites

Date: Jan 16, 2020

Author: Ryan De Vooght-Johnson

Sunscreens are widely used, but information about their possible metabolites is limited. A team from the University of Quebec, Montreal, used a combination of UHPLC and QTOF-MS to examine the metabolites from six sunscreen compounds produced by in vitro treatment with human or rat microsomes.

QbD optimization: Quicker impurity quantification for stomach drugs

Date: Jan 15, 2020

Author: Ryan De Vooght-Johnson

The stomach drugs omeprazole and esomeprazole are widely used, but their standard HPLC methods are lengthy. Researchers from AstraZeneca’s Gothenburg labs developed a new, quicker UHPLC system for omeprazole using a ‘quality by design’ (QbD) approach, examining the separation of impurities over a significant volume of ‘experimental space’.

Journal Highlight: Data‐independent acquisition‐based quantitative proteomics analysis reveals dynamic network profiles during the macrophage inflammatory response

Date: Jan 15, 2020

Author: separationsNOW

The proteome in a model of inflammation in macrophages treated with lipopolysaccharide has been characterised using data‐independent acquisition and bioinformatic analyses to reveal discrete modules and the underlying molecular mechanisms, as well as the signaling network that modulates the development of inflammation.
