Advanced LC-IMS-MS protocol for holistic metabolite analysis in wine and grape samples

The final aim of metabolomics is the comprehensive and holistic study of the metabolome in biological samples. Therefore, the use of instruments that enable the analysis of metabolites belonging to various chemical classes in a wide range of concentrations is essential, without compromising on robustness, resolution, sensitivity, specificity, and metabolite annotation. These characteristics are crucial for the analysis of very complex samples, such as wine, whose metabolome is the result of t...

Efficient feature selection for PTR-MS fingerprinting of agroindustrial products

We recently introduced the Random Forest - Recursive Feature Elimination (RF-RFE) algorithm for feature selection. In this paper we apply it to the identification of relevant features in the spectra (fingerprints) produced by Proton Transfer Reaction - Mass Spectrometry (PTR-MS) analysis of four agro-industrial products (two datasets with cultivars of Berries and other two with typical cheeses, all from North Italy). The method is compared with the more traditional Support Vector Machine - Re...

Biological control of Plasmopara viticola: where are we now?

Grapevine downy mildew, caused by Plasmopara viticola, is one of the most critical diseases on grapevine worldwide, causing relevant economic losses. Nowadays, the management of grapevine downy mildew relies mainly on the application of copper and synthetic fungicides. However, due to the occurrence of P. viticola populations resistant to fungicides and the impact of chemicals on humans and the environment, the development of eco-friendly plant protection products is highly requested. Biocont...
