Lower limb blood flow responses during higher‐ and lower‐load bilateral leg press exercise

open access: yesExperimental Physiology, EarlyView.
Abstract The local blood flow response to resistance exercise (RE) is complicated by local muscular contractions and large swings in perfusion pressure. The magnitude of these responses might vary according to exercise intensity, number of sets and number of repetitions, and as a result, the local shear environment during RE remains uncharacterized. We

Computational analysis to assess hemodynamic forces in descending thoracic aortic aneurysms

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Left: Pre‐processing. First, we perform the segmentation of the Computer Tomography angiorgraphy (angio‐CT) scans of a healthy patient, obtaining the surface of a healthy thoracic aorta with a Type III aortic arch. Then, we build nine ideal configurations with Descending Thoracic Aortic Aneurysm (DTAA), varying the aortic arch ...

Vascular smooth muscle cell mechanotransduction: Pathways, phenotypes and emerging technologies

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Vascular smooth muscle cells are exposed to mechanical stimuli from the blood flow and the extracellular matrix. The cells sense the signals from cyclic stretch, shear stress, hydrostatic pressure and matrix stiffness through specialized mechanosensors, such as mechanosensitive ion channels or cell surface receptors including ...

Regional electrical differences and arrhythmia in the rat atria: Role of sympathetic nerve distribution and function

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Atrial fibrillation commonly develops in the left atrium and pulmonary veins (PVs), and can be triggered by sympathetic nerve activity. Here, we examined regional atrial differences in sympathetic nerve distribution and function in the rat.
