ORCHESTRATING DIFFERENCE AND SIMILARITY: Black Fungibility, and the Spatial Redrawing of Racial Categories in Spanish Colonial Morocco, Sahara and Guinea

open access: yesInternational Journal of Urban and Regional Research, Volume 50, Issue 4, Page 960-981, July 2026.
Abstract In this article I dissect the spatial strategies through which the Spanish attempted to orchestrate both racial difference and similarity in the African colonies of Morocco, Western Sahara and Equatorial Guinea during the first half of the twentieth century.

Unsymmetrical Schiff Bases Efficient Ligands for the Synthesis of Organotin (IV) Complexes and 1,5‐Benzodiazepines with Anxiolytic Properties, Molecular Docking Studies

open access: yesChemistrySelect, Volume 10, Issue 2, January 15, 2025.
A series of organotin(IV) complexes is synthesized using a Schiff base ligand derived from dehydroacetic acid, salicylaldehydes, and 1,2‐phenylenediamine. The reaction also forms 1,5‐benzodiazepines, which show anxiolytic effects in mice at 1 mg/Kg. Docking studies reveal interactions with the GABA‐A receptor.

Spatio-Temporal Variation in Cyanobacteria and Epiphytic Algae of Thalassia testudinum in Two Localities of Southern Quintana Roo, Mexico

open access: yesDiversity
The leaves of Thalassia testudinum provide an ideal substrate for the establishment of small-sized algae with different morphologies that are abundant and diverse. There are few studies on epiphytism in Mexico, and most of them are floristic lists.

Las colonias escolares : una institución pedagógica de higiene preventiva en beneficio de los niños débiles de las escuelas primarias

open access: yes, 2023
This simple contribution is just a part of an investigation that we are making on school camps as pedagogical institutions of preventive hygiene in favour of the poorets children. With such a contribution, we pretend to emphasize both axes: hygiene and pedagogy, which are the foundation of the European Camp movement, born in Switzerland in 1876. We are

Effects of floral resources on honey bee populations in Mexico: Using dietary metabarcoding to examine landscape quality in agroecosystems

open access: yesEcology and Evolution, Volume 14, Issue 6, June 2024.
This study investigates how landscape diversity and climatic factors affect the populations and nutritional health of honey bee colonies in Mexico. It was found that greater landscape diversity correlates with higher pollen diversity, while areas with more agriculture and urbanization show lower bee densities.

Cervical Cancer Cells Express Markers Associated with Immunosurveillance

open access: yesJournal of Immunology Research, Volume 2019, Issue 1, 2019., 2019
Cervical cancer is the second most frequent cancer in women in Mexico, and its development depends on the presence of human papillomaviruses in the uterine cervix. These oncogenic viruses transform cells where the control over cell cycle disappears, and the capacity to induce apoptosis is absent.
