Fast interrogation of intestinal organ-on-chip devices through inverted single-plane illumination microscopy (iSPIM) using an electro-tunable lens Biomedical Optics Express 16, 2020-2032 
We have developed an inverted single-plane illumination microscope adapted for the interrogation of intestinal epithelium organ-on-chip devices. In this kind of system, samples are normally scanned in a slow fashion through motorized stages. Here, we have engineered a faster sample remote focusing scan mode by the use of an electro-tunable lens synchronized with Galvo mirrors, overcoming some limitations of previous systems. In addition, we have also engineered and optimized scaffolds recapitulating the 3D topography of the intestinal epithelium. Finally, we evaluated the performance of the system using fixed and in-vitro intestinal epithelium organ-on-chip devices, demonstrating the possibility of live imaging for several hours without distorting sample evolution.

Rubio-Canalejas, A, Admella, J, Pedraz, L, Torrents, E, (2023). Pseudomonas aeruginosa Nonphosphorylated AlgR Induces Ribonucleotide Reductase Expression under Oxidative Stress Infectious Conditions Msystems 8,
The emergence of multidrug-resistant bacteria is a serious problem worldwide. Pseudomonas aeruginosa is a pathogen that causes severe infections because it can form a biofilm that protects it from immune system mechanisms such as the production of oxidative stress. Ribonucleotide reductases are essential enzymes which synthesize deoxyribonucleotides used in the replication of DNA.

Pujol, E., Blanco-Cabra, N., Julián, E., Leiva, R., Torrents, E., Vázquez, S., (2018). Pentafluorosulfanyl-containing triclocarban analogs with potent antimicrobial activity Molecules 23, (11), 2853
Concerns have been raised about the long-term accumulating effects of triclocarban, a polychlorinated diarylurea widely used as an antibacterial soap additive, in the environment and in human beings. Indeed, the Food and Drug Administration has recently banned it from personal care products. Herein, we report the synthesis, antibacterial activity and cytotoxicity of novel N,N′-diarylureas as triclocarban analogs, designed by reducing one or more chlorine atoms of the former and/or replacing them by the novel pentafluorosulfanyl group, a new bioisostere of the trifluoromethyl group, with growing importance in drug discovery. Interestingly, some of these pentafluorosulfanyl-bearing ureas exhibited high potency, broad spectrum of antimicrobial activity against Gram-positive bacterial pathogens, and high selectivity index, while displaying a lower spontaneous mutation frequency than triclocarban. Some lines of evidence suggest a bactericidal mode of action for this family of compounds.

DAC-h3: A proactive robot cognitive architecture to acquire and express knowledge about the world and the self IEEE Transactions on Cognitive and Developmental Systems 10, (4), 1005-1022
This paper introduces a cognitive architecture for a humanoid robot to engage in a proactive, mixed-initiative exploration and manipulation of its environment, where the initiative can originate from both the human and the robot. The framework, based on a biologically-grounded theory of the brain and mind, integrates a reactive interaction engine, a number of state-of-the art perceptual and motor learning algorithms, as well as planning abilities and an autobiographical memory. The architecture as a whole drives the robot behavior to solve the symbol grounding problem, acquire language capabilities, execute goal-oriented behavior, and express a verbal narrative of its own experience in the world. We validate our approach in human-robot interaction experiments with the iCub humanoid robot, showing that the proposed cognitive architecture can be applied in real time within a realistic scenario and that it can be used with naive users.
