“These evidences will help us to accurately characterize the trophic relationships of this Cretaceous ecosystem, for which it is necessary to contrast different levels of information. This publication provides the…

The most common protostomy models, such as Drosophila or Caenorhabditis , were not an option, as they had lost this biochemical pathway. Therefore, it was necessary to find a kind…

In molecular biology, retinoic acid is a molecule known for its key role in the signaling pathways of embryonic development in vertebrates. However, there are still many unknowns about its…
