Biochemical characterization and gene structure analysis of the 24‐kDa glutathione transferase sigma from Taenia solium

open access: yesFEBS Open Bio, Volume 14, Issue 5, Page 726-739, May 2024.
Glutathione transferases (GST) are involved in detoxification and immunomodulation, allowing the establishment and development of cestodes in the host. Taenia solium has a 24‐kDa GST sigma class inducible gene that encodes a stable enzyme in a wide range of pHs and temperatures. Its enzymatic activity differs from other GSTs in the parasite, suggesting

Visualización matemática: intuición y razonamiento [PDF]

open access: yes, 2012
Mathematization is heavily sustained by intuition and visual reasoning. In this work we consider mathematical visualization not only as the process of recognizing Mathematics through images, but also as a key factor to enhance understanding and inspiring

Elucidating Structural Stability, Bandgap, and Photocatalytic Hydrogen Evolution of (H2O/DMF)@HKUST‐1 Host‐Guest Systems

open access: yesChemPlusChem, Volume 89, Issue 5, May 2024.
H2O@HKUST‐1 and DMF@HKUST‐1 composites are characterized by XRD/TGA/FT‐IR/DFT‐calculations, evidencing that H2O/DMF coordinating to Cu, present bandgaps [eV] of 3.6/3.4, and 3.55/3.26 (theoretical/experimental), raising valence‐band and lowering conduction‐band, DMF@HKUST‐1 most raise valence‐band, comparative with HKUST‐1.

Formation of hollow silver nanoparticles under irradiation with ultrashort laser pulses

open access: yesNanophotonics, Volume 13, Issue 7, Page 1149-1157, March 2024.
Abstract We have studied the formation of cavities in spherical silver nanoparticles embedded in silica, irradiated with fs laser pulses that produce an intense electronic excitation. Experimentally determined aspect ratio, i.e. the ratio between the cavity and nanoparticle size, for hollow structures formed under different irradiation conditions shows

Cortical and subcortical microstructure integrity changes after repetitive transcranial magnetic stimulation therapy in cocaine use disorder and relates to clinical outcomes

open access: yesAddiction Biology, Volume 29, Issue 2, February 2024.
We evaluated whether active repetitive transcranial magnetic stimulation over the left dorso‐lateral prefrontal cortex (dlPFC) has an effect on the white matter microstructure in cocaine use disorder (CUD) patients. For this, we acquired MRI data and assessed the clinical status.
