Ageing attenuates regional vasoconstriction during acute lowering of upper and lower limbs

open access: yesExperimental Physiology, EarlyView.
Abstract The venoarteriolar and myogenic response (VMR) is a non‐adrenergic, non‐baroreflex‐mediated mechanism that increases local vascular resistance and contributes to blood pressure (BP) regulation during orthostasis. Despite the importance of the VMR in human cardiovascular control, no information exists elucidating possible differences in the VMR

Differential contribution of T‐type voltage‐gated calcium channels to vascular reactivity in the aorta and renal artery of healthy rabbits

open access: yesExperimental Physiology, EarlyView.
Abstract figure T‐type VGCCs contribute to the contraction of the rabbit aorta and modulate both contraction and vasodilation in the rabbit renal artery. α1, alpha 1 adrenergic receptor; ATR, angiotensin II receptor; Ang II, angiotensin II; CaM, calmodulin; Cav3, T‐type voltage‐gated Ca2⁺ channels; cGMP, cyclic guanidine monophosphate; EC, endothelial ...

Exploring physiological factors underlying individual differences in exercise‐induced blood pressure responses

open access: yesExperimental Physiology, EarlyView.
Abstract Even among healthy individuals, arterial blood pressure (ABP) responses to exercise vary widely. However, the mechanisms underlying this individual variability remain unclear. To investigate these mechanisms, 29 participants performed isometric handgrip exercise at 30% of their maximum voluntary contraction, followed by postexercise muscle ...

The causative role of amyloidosis in the cardiac complications of Alzheimer's disease: a comprehensive systematic review

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustration of the bidirectional causative link between cerebral amyloid‐beta (Aβ) angiopathy and cardiovascular disease in Alzheimer's disease (AD). Common cardiovascular risk factors like microvascular thrombosis, diabetes, atrial fibrillation, hypertension and atherosclerosis lead to cerebral hypoperfusion and ...

On the role of descending drive and group III/IV muscle afferent feedback in modulating corticomotoneuronal excitability during knee‐extensor exercise

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Transcranial magnetic stimulation (TMS), cervicomedullary stimulation (CMS), and femoral nerve stimulation (FNS) were used to assess changes in corticomotoneuronal excitability induced by fatiguing submaximal knee‐extension contractions performed in three conditions: (1) voluntarily (VOL); (2) electrically evoked (EVO); and (3 ...

Physiological mechanisms underlying enhanced performance with blood flow restriction training: neuromuscular, vascular and metabolic adaptations

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend We investigated how 6 weeks of dynamic knee‐extensor interval training with blood flow restriction (BFR‐leg) and without (CTRL‐leg) impacts performance and its mechanisms using non‐invasive methods. Specifically, we used gold‐standard methods to assess neuromuscular function, vascular function using Doppler ultrasound, and near ...

Open‐Source Simulator of Imaging Near Metal at Arbitrary Magnetic Field Strengths

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 4, Page 2370-2383, April 2026.
ABSTRACT Purpose The increasing prevalence of orthopedic metallic implants necessitates optimization of MRI methods to monitor surrounding tissues and identify complications. The emergence of contemporary mid‐ and low‐field systems as promising platforms for imaging around metal requires development of new protocols optimized for these field strengths.

A Novel, Low‐Cost, Nonbiological Phantom for Training in Ultrasound‐Guided Regional Anesthesia

open access: yesSonography, Volume 13, Issue 1, March 2026.
ABSTRACT Background Trainees of ultrasound‐guided regional anesthesia (UGRA) should begin with phantoms before use on patients. The phantoms currently available have substantial drawbacks. Our aim was to develop a low‐cost homemade UGRA phantom without perishable parts, which shows sonoanatomical details and hydrodissection when injecting fluid—the ...
