Fight song: variation in singing behaviour and song structure during natural agonistic interactions in a tropical songbird, Adelaide's Warbler (Setophaga adelaidae)

open access: yesIbis, Volume 168, Issue 2, Page 766-778, April 2026.
Birds may use their singing behaviours and song structure as agonistic signals in territorial encounters. We conducted an observational study to test this hypothesis in male Adelaide's Warblers Setophaga adelaidae, a tropical songbird that defends a territory year‐round.

IgG4 anti‐CD47: Erythrophagocytosis and potential transfusion complications

open access: yesTransfusion, Volume 66, Issue 4, Page 700-711, April 2026.
Abstract Background IgG4 monoclonal anti‐CD47 for cancer immunotherapy resulted in anemia necessitating red cell (RBC) transfusions. Although the antibody readily binds to CD47 on RBCs, the mechanism underlying the anemia associated with IgG4 is poorly understood.

Isometric handgrip contraction increases tibialis anterior intrinsic motoneuron excitability in a dose‐dependent manner

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 2200-2213, 1 April 2026.
Abstract The contribution of persistent inward currents (PICs) to motoneuron firing in the lower limb typically increases after a remote handgrip contraction, believed to result from diffuse serotonergic input increases in spinal cord. We investigated whether handgrip contraction intensity, duration and/or impulse would affect PIC estimates in tibialis
