Galectin‐3 plasma levels are associated with left atrial contractile function in long‐distance runners

open access: yesExperimental Physiology, EarlyView.
Abstract High‐intensity endurance exercise induces myocardial remodelling as an adaptive response to sustained volume overload, but excessive cumulative training might also favour deleterious cardiac remodelling, including atrial fibrosis. Whether acute marathon running engages circulating fibrosis‐related biomarkers and whether these biomarkers track ...

Elevational variation in heart mass and suppression of hypoxia‐induced right ventricle hypertrophy in Andean leaf‐eared mice (Phyllotis)

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...

Transition Metal‐Free Vinylcyclopropanation of Olefins via Carbolithiation Reactions: Synthesis of 3‐Azabicyclo[3.1.0]hexanes

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 17, 1 September 2026.
Readily accessible N‐allyl‐N‐2‐bromoallylamines undergo a tandem lithiation–cyclization cascade to furnish highly substituted 3‐azabicyclo[3.1.0]hexanes. The transformation proceeds without transition metals and delivers products with excellent diastereocontrol across a broad substrate range.

Satellite Glial Cells Synthesize and Release GABA to Activate Extrasynaptic GABAA Receptors That Modulate Dorsal Root Ganglia Neuron Excitability

open access: yesGlia, Volume 74, Issue 9, September 2026.
Mechanism of synthesis, release, receptor activation, uptake, and degradation of GABA in dorsal root ganglia (DRG). Left: GABA is synthesized from putrescine in satellite glial cells (SGCs). After being released by Best1 channel, it activates GABAA receptors in sensory neurons, producing a chloride current.
