Haemodynamic responses to heat stress and hypohydration in resting and exercising humans: Implications for the regulation of skeletal muscle blood flow

, 2010
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Heat stress-induced hyperthermia and exercise-induced hypohydration are associated with marked alterations in limb and systemic haemodynamics in humans ...

Effect of isoflurane on skin-pressure-induced vasodilation.

, 2003
Since general anesthesia has been shown to attenuate endothelium-dependent vasodilation, it was of interest to verify whether general anesthesia would modify skin vasodilation in response to local pressure application, which is endothelium dependent.

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

Deep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Hypoxia-reoxygenation impairs NO-mediated vasodilation in rat lungs

, 1996
Isolated rat lungs subjected to hypoxia-reoxygenation (H/R) were used to study NO-mediated pulmonary vasodilation during oxidant-induced vascular injury.

Association of COPD with adverse outcomes in heart failure patients with preserved ejection fraction

ESC Heart Failure, Volume 12, Issue 2, Page 799-808, April 2025.
Abstract We performed a systematic review and meta‐analysis to detect the impact of chronic obstructive pulmonary disease (COPD) on the prognosis of heart failure patients with preserved ejection fraction (HFpEF). We systematically screened eligible literature from three electronic databases, PubMed, EMBASE and Cochrane Library, up to April 2023.

OGG1 Preserves Endothelial-Dependent Vasodilation and Regulates the Frequency and Spatial Area of Endothelial Calcium Signals

Biomolecules
Endothelial calcium dysregulation underlies impairments in endothelial-dependent vasodilation (EDV), contributing to vascular disease progression. Repletion of 8-oxoguanine DNA glycosylase (OGG1), an enzyme involved in base excision repair, has been ...

Biomarkers of lung congestion and injury in acute heart failure

ESC Heart Failure, Volume 12, Issue 2, Page 781-789, April 2025.
Abstract Acute heart failure (AHF) classification and management are primarily based on lung congestion and/or hypoperfusion. The quantification of the vascular and tissue lung damage is not standard practice though biomarkers of lung injury may play a relevant role in this context.

Adenosine contributes to hypoxia-induced forearm vasodilation in humans

, 1999
In humans, hypoxia leads to increased sympathetic neural outflow to skeletal muscle. However, blood flow increases in the forearm. The mechanism of hypoxia-induced vasodilation is unknown.
