Carotid artery dissection linked to intermittent apnoeic swimming: A case–control study

Experimental Physiology, EarlyView.
Abstract Internal carotid artery (ICA) dissection is a rare and potentially devastating cause of cerebral ischaemia, initiated by an intimal tear or rupture of the vasa vasorum, that can lead to an intraluminal thrombus, vascular stenosis, occlusion, or dissecting aneurysm formation.

A comparison of normobaric and hypobaric hypoxia effects on cerebrovascular response pre and post maximal exercise

Experimental Physiology, EarlyView.
Abstract A lack of consensus remains on whether normobaric hypoxia (NH) and hypobaric hypoxia (HH) may differentially impact physiological factors affecting cerebrovascular regulation, particularly with an additional strenuous exercise component. We sought to compare the acute effects of NH and HH on global cerebral blood flow (gCBF) at an altitude ...

Passive heat therapy is feasible but does not affect cardiometabolic health outcomes in persons with spinal cord injury – a pilot study

Experimental Physiology, EarlyView.
Abstract Passive heat therapy can improve cardiometabolic health outcomes in some clinical populations, making it a potential therapeutic tool for individuals with spinal cord injury (SCI), who exhibit elevated cardiometabolic disease risk and face barriers to physical activity.

Adenine nucleotide translocator and ATP synthase cooperate in mediating the mitochondrial permeability transition

The Journal of Physiology, EarlyView.
Abstract figure legend Both ATP synthase and adenine nucleotide translocator (ANT) play key roles in mediating the permeability transition. The contribution of ANT becomes evident in the presence of atractylate (ATR) at pH 6.5, a condition that prevents ATP synthase channel activity. At pH 7.4, this effect is minimal, suggesting a critical role for ATP

Metabolic stimulation improves bioenergetics and haematologic indices of circulating erythrocytes from sickle cell mice

The Journal of Physiology, EarlyView.
Abstract figure legend Metabolic stimulation improves bioenergetics, redox state, hydration and hematologic indices of circulating erythrocytes from sickle cell mice. Retained mitochondria in circulating RBCs from sickle mice are a source of RBC ATP as mitochondria function (ETC, electron transport chain) inhibitors [rotenone, a mitochondrial complex I

Anatomical and functional mapping of vagal nociceptive sensory nerve subsets innervating the mouse lower airways by intersectional genetics

The Journal of Physiology, EarlyView.
Abstract figure legend We used an intersectional approach with recombinase‐expressing mice and adeno‐associated virus to map and modulate distinct nociceptive afferents in the vagal ganglia. TRPV1+P2X2+ neurons resided in the nodose ganglion (N), innervated the lungs (many projected into the alveoli) but not the trachea, and projected to the nucleus ...

Multiscale mechanistic modelling of heterogeneity in cardiac sub‐cellular calcium handling accounting for variable t‐system density

The Journal of Physiology, EarlyView.
Abstract figure legend Illustration of spatial calcium dynamics (left panels) and the state cycle approximation (middle panel) that enables reduced simulation of spatially dependent dynamics without explicit description of space (right panels). The selected example here illustrates a spontaneous calcium wave, showing temporal snapshots of local calcium

The role of group III/IV afferent feedback in the ventilatory, pressor and metabolic responses to exercise in normoxia and hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Participants completed cycling exercise with (placebo) and without (25 µg intrathecal fentanyl) intact group III/IV muscle afferent feedback in three settings: normoxia, acute hypoxia and chronic hypoxia after 7–9 days of acclimatisation (∼3800 m). Blocking afferent feedback suppressed exercise hyperpnoea across all environments,
