Test–retest reliability of Doppler ultrasound‐based leg blood flow assessments during exercise in patients with chronic obstructive pulmonary disease

Experimental Physiology, EarlyView.
Abstract Doppler ultrasound may be used to assess leg blood flow (Q̇leg${{\dot{Q}}_{{\mathrm{leg}}}}$), but the reliability of this method remains unexplored in patients with chronic obstructive pulmonary disease (COPD), where between‐subject variability may be larger than healthy due to peripheral vascular changes.

Chemoreflex function in pulmonary diseases – A review

The Journal of Physiology, EarlyView.
Abstract figure legend Chemoreflex activation in respiratory diseases and COVID‐19 populations. Abstract The chemoreflex is a vital protective reflex that is crucial in restoring normal blood gas and pH levels. The carotid bodies are peripheral chemoreceptors activated by hypoxia (primarily), hypercapnia, acidaemia, temperature, lactate and potassium ...

Differentiated Presynaptic Input to OLMɑ2 Cells Along the Hippocampal Dorsoventral Axis: Implications for Hippocampal Microcircuit Function

Hippocampus, Volume 35, Issue 5, September 2025.
ABSTRACT The dorsal and ventral hippocampus have distinct processing properties, but it remains unclear if interneuron subtypes differ in connectivity along the dorsoventral axis. Oriens lacunosum‐moleculare (OLM) interneurons, identified by the Chrna2 gene, are known to regulate memory processes differently along this axis. OLMɑ2 cells bidirectionally

Photoaffinity labeling coupled to MS to identify peptide biological partners: Secondary reactions, for better or for worse?

Mass Spectrometry Reviews, Volume 44, Issue 5, Page 715-756, September/October 2025.
Abstract Affinity photolabeling is a smart method to study noncovalent and transient interactions and provide a submolecular picture of the contacts between interacting partners. In this review, we will focus on the identification of peptide partners using photoaffinity labeling coupled to mass spectrometry in different contexts such as in vitro with a
