Antidepressant Misuse in Esports: A Review of Pharmacology, Adverse Effects, Pharmacokinetics and Biomatrix‐Based Detection for Anti‐Doping Applications

Drug Testing and Analysis, EarlyView.
This review highlights the misuse of antidepressants as potential cognitive‐enhancing agents in Esports. Despite pharmacological effects that overlap with those of psychostimulants, antidepressants remain an under‐recognised source of doping in Esports.

Dispersive Liquid-Liquid Microextraction Followed by HS-SPME for the Determination of Flavor Enhancers in Seafood Using GC-MS

Foods, 2022
The determination of flavor compounds using headspace solid-phase microextraction (HS-SPME) combined with gas chromatography–mass spectrometry (GC-MS) can be severely interfered with by complex food matrices in food systems, especially solid samples.

Impact of climate‐induced compositional shifts of ethanol and acidity on aroma release and perception in red wine: a case study on γ‐nonalactone and massoia lactone

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change‐driven warming is increasing wine ethanol, promoting an atypical convergence between pH and titratable acidity (TA), and favouring the accumulation of specific wine volatiles: γ‐nonalactone (γ‐C9) and massoia lactone (MLac).

Potential Applications of HS-SPME/GC in Oxidized Vegetable Oils [PDF]

Journal of Food Science and Engineering, 2012
Headspace solid phase microextraction chromatography (HS-SPME/GC) was evaluated as a tool in determining the rate of oxidation in oxidized soybean oil samples by measuring the production of hexanal as a secondary major volatile breakdown product of linoleic acid. Samples of the headspace taken from sealed 20 mL vials, incubated 30 min at 50 °C followed
