Increases in skin perfusion and blood oxygen in the non‐exercising human limbs during exercise in the heat: Implications for control of circulation

Experimental Physiology, EarlyView.
Abstract Blood flow in the inactive limb tissues and skin is widely thought to decline during incremental exercise to exhaustion due to augmented sympathoadrenal vasoconstrictor activity, but direct evidence to support this view is lacking. Here, we investigated the inactive‐forearm haemodynamic (Q̇forearm${\dot{Q}}_{\mathrm{forearm}}$) and oxygenation

Obrazowanie kompleksu łechtaczkowego w diagnostyce seksuologicznej

Menopause Review, 2010
The ability to measure physiological parameters of sexual function in women has lagged far behind that inmen. Female sexual arousal is an important aspect of female sexuality, yet it is a difficult phenomenon to investigate.The purpose of this article is

Whole-body plethysmography

, 2020
The word plethysmograph is derived from the Greek plethusmos (enlargement), and is related closely to plethus (fullness) and plethora (fullness). Indeed, the fundamental function of a whole-body plethysmograph is the measurement of intrathoracic gas ...

Intermittent hand and forearm immersion in 20°C water attenuates thermal, cardiovascular, and perceptual strain in older adults during heat stress

Experimental Physiology, EarlyView.
Abstract Adults >65 years of age experience deleterious health effects during extreme heat events at a greater rate than any other age cohort. The purpose of this study was to identify the effectiveness of acute intermittent hand and forearm (H+F) water immersion and/or chronic (7 week) folic acid supplementation on reducing thermal and cardiovascular ...

The role of strain gauge plethysmography in the assessment of patients with suspected deep vein thrombosis

Suspicion of deep vein thrombosis (DVT) is a common reason for medical referral to hospital. Clinical signs and symptoms are notoriously unreliable, hence there is the need for objective testing.

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 ...

Is resting muscle sympathetic nerve activity related to peripheral or cerebrovascular haemodynamics at high altitude? A retrospective analysis

Experimental Physiology, EarlyView.
Abstract High‐altitude hypoxia elicits several profound physiological responses, including substantial increases in muscle sympathetic nerve activity (MSNA); however, the association of this heightened MSNA with cardiovascular and cerebrovascular haemodynamics remains unclear in lowlanders and indigenous highlander populations.
