Gas chromatography coupled to mass spectrometry is the most frequent tool for metabolomic
profiling of low molecular weight metabolites. Its suitability in health survey is beyond doubt…

Alzheimer's disease is closely related to abnormal metabolism of phospholipids from neural
membranes, so that the study of their dyshomeostasis could be of great interest for the …

In this study, we demonstrated the potential of direct infusion mass spectrometry for the
lipidomic characterization of Alzheimer's disease. Serum samples were extracted for lipids …

There is high interest in the discovery of early diagnostic biomarkers of Alzheimer's disease,
for which metabolomics exhibits a great potential. In this work, a metabolomic approach …

Metal dyshomeostasis is closely related to Alzheimer's disease, so the characterization of
the metal profiles in these patients is of special interest for studying associated …

Mercury and arsenic are two elements of undoubted importance owing to their toxic character.
Although speciation of these elements has been developed separately, in this work for the …

The use of atmospheric pressure photoionization is not widespread in metabolomics,
despite its considerable potential for the simultaneous analysis of compounds with diverse …

Selenium (Se) is a micronutrient involved in important health functions and it has been
suggested to shape gut microbiota. Limited information on Se assimilation by gut microbes and …

Algae and aquatic macrophytes are capable of accumulating heavy metals up to concentrations
several orders of magnitude higher than those existing in their surrounding environment…

The fact that the essential or toxic character of elements is species specific has encouraged
the development of analytical strategies for chemical speciation over the last twenty years; …
