Optimization and validation of a LC-HRMS method for aflatoxins determination in urine samples [PDF]

Mycotoxin Research, 2020
Mycotoxins' exposure by inhalation and/or dermal contact can occur in different branches of industry especially where heavily dusty settings are present and the handling of dusty commodities is performed. This study aims to explore the possible contribution of the occupational exposure to aflatoxins by analysing urine samples for the presence of ...

Discrimination of Bipolar Disorder and Schizophrenia Patients Based on LC-HRMS Lipidomics. [PDF]

Metabolites
Background/Objectives: Schizophrenia (SCH) and bipolar disorder (BD) share overlapping symptoms and genetic factors, making differential diagnosis challenging and often leading to misdiagnosis. This study aimed to identify potential lipid biomarkers of serum capable of distinguishing BD from SCH.

A multiplatform metabolomic approach to characterize fecal signatures of negative postnatal events in chicks: a pilot study

Journal of Animal Science and Biotechnology, 2019
Background Negative experiences in early life can induce long-lasting effects on the welfare, health, and performance of farm animals. A delayed placement of chicks in rearing houses has negative effects on their performance, and results in fecal ...

Analysis of electrochemical and liver microsomal transformation products of lasalocid by LC/HRMS

Rapid Communications in Mass Spectrometry, 2022
Rationale Lasalocid (LAS), an ionophore, is used in cattle and poultry farming as feed additive for its antibiotic and growth‐promoting properties. Literature on transformation products (TP) resulting from LAS degradation is limited.

Non-targeted analysis of unexpected food contaminants using LC-HRMS [PDF]

Analytical and Bioanalytical Chemistry, 2018
A non-target analysis method for unexpected contaminants in food is described. Many current methods referred to as "non-target" are capable of detecting hundreds or even thousands of contaminants. However, they will typically still miss all other possible contaminants. Instead, a metabolomics approach might be used to obtain "true non-target" analysis.

Critical assessment of the chemical space covered by LC-HRMS non-targeted analysis

Environmental Science & Technology, 2023
Non-targeted analysis (NTA) has emerged as a valuable approach for comprehensive monitoring of chemicals of emerging concern (CECs) in the exposome. The NTA approach, theoretically, is able to identify compounds with diverse physicochemical properties and sources.
