Automated and Fully Validated High‐Throughput LC‐MS/MS Assay for Analyzing Multiple Drugs of Abuse in Oral Fluids Using Novel Features in Sample Preparation and Chromatographic Conditions

open access: yesJournal of Mass Spectrometry, Volume 60, Issue 5, May 2025.
ABSTRACT Oral fluid sampling offers advantages over other biological matrices, mainly due to its noninvasive procedure avoiding privacy intrusion. The fully automated sample preparation procedure is based on salting‐out assisted liquid–liquid extraction (SALLE) combined with high‐efficiency LC‐MS/MS methods for both screening and confirmation of 37 ...

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

open access: yesMass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Erectile dysfunction in cardiovascular patients: A prospective study of the eNOS gene T‐786C, G894T, and INTRON variable number of the tandem repeat functional interaction

open access: yesAndrology, Volume 13, Issue 4, Page 794-803, May 2025.
Abstract Background Cardiovascular disease induces erectile dysfunction modulated by endothelial nitric oxide synthase enzyme and an impaired ejection fraction that restricts penis vascular congestion. However, the mechanisms regulating endothelial dysfunction are not understood.

Characterisation and correction of polarisation effects in fluorescently labelled fibres

open access: yesJournal of Microscopy, Volume 298, Issue 2, Page 185-203, May 2025.
Summary Many biological structures take the form of fibres and filaments, and quantitative analysis of fibre organisation is important for understanding their functions in both normal physiological conditions and disease. In order to visualise these structures, fibres can be fluorescently labelled and imaged, with specialised image analysis methods ...

Elevated Cholinesterase Activity and the Metabolic Syndrome—Dissecting Fatty Liver, Insulin Resistance and Dysglycaemia

open access: yesLiver International, Volume 45, Issue 5, May 2025.
ABSTRACT Background and Aims While low plasma butyrylcholinesterase (BChE) is a well‐established marker of reduced liver synthesis capacity, the clinical significance of elevated BChE is unclear. In small studies, high BChE has long been suspected in hepatic steatosis and metabolic syndrome.
