Impaired vasocontractile responses to adenosine in chorionic vessels of human term placenta from pregnant women with pre-existing and gestational diabetes. Diabetes and Vascular Disease Research, 15(6), 528-540. https://doi.org/10.1177/1479164118790904

Background: There is clinical and experimental evidence for altered adenosine signalling in the fetoplacental circulation in pregnancies complicated by diabetes, leading to adenosine accumulation in the placenta. However, the consequence for fetoplac...

Coronary artery hypoxic vasorelaxation is augmented by perivascular adipose tissue through a mechanism involving hydrogen sulfide and cystathionine-β-synthase (2018)
Journal Article
Donovan, J., Wong, P., Garle, M., Alexander, S. P., Dunn, W. R., & Ralevic, V. (in press). Coronary artery hypoxic vasorelaxation is augmented by perivascular adipose tissue through a mechanism involving hydrogen sulfide and cystathionine-β-synthase. Acta Physiologica, Article e13126. https://doi.org/10.1111/apha.13126

Aim: Hypoxia causes vasodilatation of coronary arteries which protects the heart from ischaemic damage through mechanisms including the generation of hydrogen sulfide (H2S), but the influence of the perivascular adipose tissue (PVAT) and myocardium i...

A critical role for cystathionine-β-synthase in hydrogen sulfide-mediated hypoxic relaxation of the coronary artery (2017)
Journal Article
Donovan, J., Wong, P., Roberts, R. E., Garle, M., Alexander, S. P., Dunn, W. R., & Ralevic, V. (2017). A critical role for cystathionine-β-synthase in hydrogen sulfide-mediated hypoxic relaxation of the coronary artery. Vascular Pharmacology, 93-95, https://doi.org/10.1016/j.vph.2017.05.004

Hypoxia-induced coronary artery vasodilatation protects the heart by increasing blood flow under ischemic conditions, however its mechanism is not fully elucidated. Hydrogen sulfide (H2S) is reported to be an oxygen sensor/transducer in the vasculatu...

Sensory innervation of perivascular adipose tissue: a crucial role in artery vasodilation and leptin release (2017)
Journal Article
Baker, H. A., Dunn, W. R., Daly, C., & Ralevic, V. (2017). Sensory innervation of perivascular adipose tissue: a crucial role in artery vasodilation and leptin release. Cardiovascular Research, 113(8), 962-972. https://doi.org/10.1093/cvr/cvx062

Aims: Electrical field stimulation (EFS) elicits robust sensory neurogenic relaxation responses in the rat isolated mesenteric arterial bed but these responses are absent or difficult to demonstrate in isolated arteries. We believe that this mismatch... Read More about Sensory innervation of perivascular adipose tissue: a crucial role in artery vasodilation and leptin release.
