Arterial stiffness is strongly associated with vascular aging and pathology and can be assessed in many ways. Existing devices for measuring central arterial stiffness, such as carotid-femoral pulse wave velocity (PWV), are limited by high costs and the ...

Abstract Optical coherence tomography (OCT) enables visualization and quantification of the cutaneous microvasculature, yet no study has compared responses to distinct forms of heating in humans. We hypothesized that local skin heating (LH) would evoke larger responses in microvascular diameter, velocity, flow and density than passive whole‐body ...

Microvascular endothelial function is blunted in postmenopausal females with frequent hot flushes
Abstract Hot flushes of menopause are associated with elevated blood pressure (BP) and diminished macrovascular endothelial function, an initiating factor in the onset of atherosclerosis. Whether microvascular endothelial function is impaired in females with hot flushes, however, remains unknown.

This early feasibility test explores impedance plethysmography (IPG) for detecting toe pulse waves using a setup suited for miniaturized devices. Conventional tests often miss micro-circulatory impairment, which is critical for wound healing and limb ...

Abstract The two‐kidney, one‐clip (2K1C) model produces renovascular hypertension. The effects on the clipped kidney (CK) are well described, while the non‐clipped kidney (NCK) is used as a model to evaluate the effects of high blood pressure. Although most of these effects have been described at later stages of 2K1C hypertension, it remains unclear ...

Abstract Exertional dyspnoea is a debilitating symptom in chronic obstructive pulmonary disease (COPD) and often persists after the cessation of exercise. The underlying mechanisms are not fully understood, and a potential contributing factor that has not previously been investigated is alveolar–capillary membrane breaching with extravasation of fluid ...
