Pharmacological manipulation of the immediate effects of spinal trauma in neonatal rats reveals a crucial role for TRPV4 receptors

The Journal of Physiology, EarlyView.
Abstract figure legend A, schematic illustration of the ventral aspect of an ex vivo preparation of the entire CNS from a neonatal rat subjected to a calibrated thoracic impact. The trauma induced a large depolarising injury potential (DIP, black trace) recorded from the L5 ventral root (VRrL5), which was markedly reduced by transient receptor ...

Hydroxyl radical footprinting modification reveals an intradomain communication pathway in EFL1 disrupted by a Shwachman‐Diamond syndrome‐associated mutation

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Shwachman‐Diamond syndrome (SDS) is a rare genetic disorder characterized by pancreatic insufficiency and neutropenia. While most cases are linked to mutations in the SBDS gene, some involve mutations in the GTPase EFL1. This protein works with SBDS to release the anti‐association factor eIF6 from the 60S ribosomal subunit during ribosome ...

Understanding cell‐penetrating peptide mechanisms using computational electrophysiology simulations

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Cell‐penetrating peptides (CPPs) can enter cells without inducing cytotoxicity and can be coupled with cargo molecules to be used to deliver drugs, DNA, or nanoparticles into cells. The peptide‐membrane interactions driving the internalization mechanism are not completely understood. In this study, we introduce Computational Electrophysiology (

Trazabilidad de las mediciones realizadas con activímetros en medicina nuclear

Nucleus, 2008
En medicina nuclear, las dosis del radiofármaco administradas se expresan mediante la actividad del radionucleido en el preparado. La medición de esa actividad se realiza en el activímetro y resulta primordial para garantizar la comparabilidad nacional e

Can Peer Victimization Invalidate the Positive Effect of Emotional Intelligence on Adolescents' Health‐Related Quality of Life?

Journal of School Health, Volume 96, Issue 4, April 2026.
ABSTRACT Background Emotional intelligence (EI) is a key factor in adolescents' health‐related quality of life (HRQoL). Previous research has shown that higher EI is associated with better HRQoL outcomes. However, its protective role may be weakened by adverse experiences such as peer victimization.

SmallTalk: a novel small‐sized fusion tag for peptide expression and purification

FEBS Open Bio, Volume 16, Issue 3, Page 461-473, March 2026.
The SmallTalk fusion tag allows for the efficient expression and purification of soluble recombinant proteins or peptides in Escherichia coli. Testing with SmallTalk‐GFP confirmed that the proteins were soluble and folded correctly, while SmallTalk‐Bin1b maintained its antimicrobial activity against various bacterial isolates. This streamlined workflow
