Miguel Reina; Itzel Guerrero-Ri´os; Antonio Reina – Journal of Chemical Education, 2022
We describe a remote pedagogical approach based on chemical thinking to study metal-carbonyl complexes by analyzing simulated IR spectra. The proposed approach, implemented due to the COVID-19 pandemic, can be employed in classrooms that have very limited laboratory equipment for evaluating toxic metal-carbonyl compounds, as well as for…

Márquez-Caraveo, María Elena; Ibarra-González, Isabel; Rodríguez-Valentín, Rocío; Ramírez-García, Miguel Ángel; Pérez-Barrón, Verónica; Lazcano-Ponce, Eduardo; Vela-Amieva, Marcela – Journal of Autism and Developmental Disorders, 2021
The objective of our study was to evaluate the frequency of treatable inborn errors of metabolism (IEM) in a clinical sample of Mexican children and adolescents with neurodevelopmental disorders (NDD). Amino acids and acylcarnitines in blood samples of 51 unrelated children and adolescents were analyzed by tandem mass spectrometry to detect…
