Last week, I successfully defended my Doctoral Thesis, entitled "Advanced Mass Spectrometric Techniques for Screening and Metabolomics Approaches in Food and Nutrition" at Universitat Jaume I. Thank you to all the collaborators and institutions who made this work possible.

Evaluating human serum for trace levels of lipophilic organic chemical... sciencedirect.com/science/articl…

This collection is associated with S132 | UJIGCAPCICCS | A GC-APCI-IMS-HRMS CCS on the NORMAN Suspect List Exchange. @NORMAN_network norman-network.com/nds/SLE/ Thanks @ESchymanski for the support on sharing this dataset. I hope it can be useful for future screening applications!🎯

📚This library of GC-APCI+ amenable contaminants contains CCS, Linear Retention Index (LRI), MS/MS fragments and chemical class information for 250 substances (pesticides, PAHs, PCBs, PDBEs, OPEs), including 398 CCS values for various adducts and in source fragments.

🚨An extended version of the CCS library published during my thesis (Izquierdo-Sandoval et al. (2022) Anal. Chem. 2022, 94, 9040−9047, DOI: 10.1021/acs.analchem.2c01118) is now available in CSV format in Zenodo: zenodo.org/records/158384… DOI: 10.5281/zenodo.15831151

📢 ¡¡ABIERTAS LAS INSCRIPCIONES PARA LAS III JORNADAS DE JÓVENES INVESTIGADORES DE LA @SEEM_MS!! 🥼 Si eres joven una investigadora/or (predoc, postdoc junior, técnico, junior researcher, etc.), ¡no puedes perderte estas jornadas! e-seem.org/Jornadas-Joven…

Many thanks to the co-authors @tportole @juanvisancho and Félix Hernández for their valuable help and collaboration.

We explored the capabilities of GC-APCI-IMS-QTOF MS and GC-EI-QOrbitrap MS for the wide-scope screening of organic microcontaminants in environmental and food safety applications. Our findings provide valuable insights into the strengths and limitations of each technique.

⚠️⚠️⚠️ L'UJI suspèn les activitats docents, investigadores i administratives en el dia d'avui, 31 d'octubre de 2024. Atès que el Servei 112 ha pujat aquest matí el nivell de preemergència per al litoral sud de Castelló a color taronja (nivell important) i atenent a les recomanacions de les autoritats per a evitar desplaçaments innecessaris, us COMUNIQUEM que l'UJI suspèn les activitats docents, investigadores i administratives en el dia d'avui. Tot i això, les persones que a hores d'ara ja estiguen en el seu lloc de treball, poden seguir en el seu lloc. Les persones que hagen de desplaçar-se, poden romandre en casa. Les absències del lloc de treball tindrà el mateix tractament que el d'una situació de malaltia sobrevinguda. Seguirem atents a l'evolució del temps i informarem de qualsevol canvi.

Thrilled to share our latest review on plant proteins 🌱 and gut health, published in Trends in Food Science & Technology! We discuss the journey of plant proteins and their impact on gut microbes and the intestine Grateful for the collaboration ⬇️ sciencedirect.com/science/articl…

This work was carried out during my stay at @FQD_WUR and @WUR_HNH. Many thanks, @joseprubert, for this opportunity Also, thanks to the other co-authors, Xiang Duan, Christos Frygannas, @tportole, and @juanvisancho, and to @IupaUji @UJIuniversitat for supporting my stay.

🆕Our recent research combines in vitro digestion and colonic fermentation with a comprehensive metabolomics approach to compare the interactions of beef🥩and plant-based🌱 patties 🍔with gut microbiota. More info ⬇️⬇️⬇️⬇️⬇️⬇️⬇️ sciencedirect.com/science/articl…

📰Our recent study finds a distinct pattern of gut microbial metabolites from plant-based vs beef patties 🍔.🥩Beef promotes GMMs like γ-glutamyl amino acids, while 🌱PBMA boosts N-acyl amino acids. Thanks @libes17dis & Xiang Duan👏 @WUR_HNH @FQD_WUR sciencedirect.com/science/articl…
