LC-HRMS analysis of 13 classes of pharmaceutical substances in food supplements.

Food supplements should not contain substances considered unsafe or pose a health risk to consumers. In recent years illegal adulterants have been found in various functional foods without notification of their presence or amount in the labelling. In this study, a validated method was developed and applied as a screening method to detect 124 forbidden substances belonging to 13 classes of compounds in food supplements.

A simple and sensitive method for the determination of methylene blue and its analogues in fish muscle using UPLC-MS/MS.

A new, simple and sensitive method for determining and confirming methylene blue and its analogues such as azure A, azure B, azure C, thionine, and new methylene blue in fish muscles have been developed. The method is based on acetonitrile extraction followed by extract purification using dispersive solid-phase extraction (dSPE) with basic aluminium oxide (ALN) and solid-phase extraction (SPE) using primary and secondary amines (PSA) sorbent in matrix adsorption mode. The separation and detection of the dyes in the fish extract are achieved within 5 min by ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) using an octadecyl analytical column with a mixture of acetonitrile, methanol and 0.

Undeclared (Poly)phosphates Detection in Food of Animal Origin as a Potential Tool toward Fraud Prevention.

(Poly)phosphates are approved as water-preserving and emulsifying agents that improve the appearance and consistency of many food products. The labelling of added (poly)phosphates is essential for protecting vulnerable population groups and to prevent unfair trade practices resulting in economic fraud. The problems with (poly)phosphates' utilisation concerns both analytical and legislative issues, such as: (1) their straightforward detection; (2) excessive addition altering freshness perception and misleading consumers; (3) uncontrolled usage increasing foodstuff weight; (4) application in products where they are not permitted; and (5) no indication on the label.

Poaching of endangered species in Mediterranean Sea: Alopias vulpinus.

Death of captive-bred vultures caused by flunixin poisoning in Italy.

Among non steroidal anti-inflammatory drugs (NSAIDs) diclofenac is considered the main cause for the decline of vulture populations in the Indian subcontinent since the '90 s. Chemical analysis showed high levels of flunixin (31,350 μg/kg) in beef which three captive Gyps vultures fed on, later dying with severe visceral gout. Levels in dead vultures' organs and tissues ranged from 4 to 38.

How Breath-Control Can Change Your Life: A Systematic Review on Psycho-Physiological Correlates of Slow Breathing.

The psycho-physiological changes in brain-body interaction observed in most of meditative and relaxing practices rely on voluntary slowing down of breath frequency. However, the identification of mechanisms linking breath control to its psychophysiological effects is still under debate. This systematic review is aimed at unveiling psychophysiological mechanisms underlying slow breathing techniques (<10 breaths/minute) and their effects on healthy subjects.

Multi-drug ultraperformance liquid chromatography/tandem mass spectrometry method to quantify antimicrobials in feeding stuffs at carry-over level.

Rationale: Carry-over is an undesirable contamination from medicated to non-medicated during the production of feedingstuffs. In 2014 the European Parliament and the Council started working to produce a new regulatory act that will fix tolerable levels of drugs by carry-over in non-target feed to have a harmonized practice to evaluate this contamination by veterinary drugs.

Methods: We developed a rapid and effective multi-analyte method coupling ultraperformance liquid chromatography to tandem mass spectrometry (UPLC/MS/MS) for the detection of 37 drugs belonging to different classes of antimicrobials (sulfonamides, tetracyclines, macrolides, quinolones, pleuromutilins and streptogramins) in feeds at carry-over levels.

Intake estimates of dioxins and dioxin-like polychlorobiphenyls in the Italian general population from the 2013-2016 results of official monitoring plans in food.

The implementation of the European Union strategy for polychlorodibenzo-dioxins and -furans (PCDD/Fs), and dioxin-like polychlorobiphenyls (DL-PCBs) is determining a general reduction of their presence in the environment and in the food chain. The most important route for human exposure to these substances is food consumption and, as a consequence, a progressive decrease of their dietary intake has been observed in the last decades. In this context, it seemed worth updating the PCDD/F and DL-PCB intake estimation for the Italian population.

Occurrence of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and polychlorinated biphenyls (PCBs) in eggs from free-range hens in Campania (southern Italy) and risk evaluation.

Hens' eggs collected in home-producing farms located in different areas of the Campania region of southern Italy were analysed for six NDL-polychlorobiphenyls (PCB indicators), 17 polychlorodibenzo-p-dioxins (PCDDs) and polychlorodibenzofurans (PCDFs), and 12 congeners of dioxin-like PCBs (DL-PCBs). In the investigated area, waste from civil, industrial and hospital activities was illegally dumped and in many cases burned, so the area is called the 'Land of fire'. This illicit practice has been considered the main source of pollution in this territory and the cause of the persistent organic pollutants' (POPs) contamination in the neighbouring lands intended for agricultural use and livestock.
