A prospective evaluation of plasma phospholipid fatty acids and breast cancer risk in the EPIC study

Background Intakes of specific fatty acids have been postulated to impact breast cancer risk but epidemiological data based on dietary questionnaires remain conflicting. Materials and methods We assessed the association between plasma phospholipid fatty acids and breast cancer risk in a case–control study nested within the European Prospective Investigation into Cancer and Nutrition study.

Semiautomated determination of neonicotinoids and characteristic metabolite in urine samples using TurboFlow™ coupled to ultra high performance liquid chromatography coupled to Orbitrap analyzer

A semiautomated method based on ultra-high performance liquid chromatography (UHPLC) coupled to Orbitrap high resolution mass spectrometry has been developed for the determination of neonicotinoids (imidacloprid, acetamiprid, clothianidin, dinotefuran, nitenpyram, thiacloprid and thiamethoxam) and the metabolite acetamiprid-n-desmethyl in urine samples. Two automated methods were tested (solid-phase extraction “SPE” and turbulent flow chromatography “TurboFlow™”), obtaining the…
