Mitochondrial Markers COI and 16S rRNA for the Molecular Identification of Parrots and Macaws Recovered From Illegal Trafficking in Three Areas of Colombia

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We molecularly characterized parrots (Amazona spp.) and macaws (Ara spp.) rescued from illegal trafficking in Colombia using two mitochondrial markers (COI and 16S rRNA). The COI gene showed high resolution for species identification and revealed considerable intraspecific diversity, while 16S rRNA displayed limited taxonomic resolution.

Characterisation of Antisense Oligonucleotides by Ion‐Pair Reversed‐Phase UHPLC‐HRMS: Method development using Design of Experiments

Journal of Mass Spectrometry, Volume 61, Issue 4, April 2026.
ABSTRACT The quality control of therapeutic antisense oligonucleotides (ASOs) poses significant analytical challenges due to the complexity of their synthesis and degradation processes and the need to ensure the safety and efficacy of active pharmaceutical ingredients (APIs).
