Abstract figure legend A preclinical large‐animal model of hypertensive heart failure with preserved ejection fraction (HFpEF) was used to examine the role of purinergic P2X3 receptor signalling during treadmill exercise. Animals were instrumented with either thoracic cardiac output and coronary flow probes or abdominal renal and hindlimb blood flow ...

Pulmonary hypertension is driven by dynamic crosstalk beyond the physical connection between the heart and lung, involving neurohormonal systems, immune pathways, and peripheral organs. This review highlights how multisystem signaling contributes to disease progression and may reveal new diagnostic and therapeutic targets.

Selective potentiation of peripheral chemoreflex sensitivity in obstructive sleep apnea.
The chemoreflexes are an important mechanism for regulation of both breathing and autonomic cardiovascular function. Abnormalities in chemoreflex mechanisms may be implicated in increased cardiovascular stress in patients with obstructive sleep apnea ...

ABSTRACT Aim We aimed to evaluate an innovative dose–response approach to assess the metaboreflex with control of intramuscular metabolic perturbation (concept of metaboreflex gain). We also investigated potential sex differences in the metaboreflex using this new approach.

ABSTRACT The cardiovascular response to acute exercise is mediated by the autonomic nervous system (ANS) control mechanisms that modulate vascular resistance to support blood pressure and ensure adequate blood flow to active muscles. These autonomic neurocirculatory control mechanisms include a feedforward mechanism, known as central command, and three

Postnatal developmental changes in the laryngeal chemosensory cell clusters of rats
Chemosensory cell clusters appeared in the rat larynx 2 days after birth and were already connected to afferent nerve fibers. Their number increased until 3 weeks of age, then stabilized while continuing to grow through the addition of new cells. Because their number reached a plateau around the time of weaning, their development may be linked to ...
