The intracellular second messenger, cyclic guanosine monophosphate (cGMP), a soluble guanylate cyclase (GC) product, is a primary mechanism for the transduction of a nitric oxide (NO)-initiated signal in the central nervous system. NO is produced from L-arginine by neuronal nitric oxide synthase (NOS), which is found in sympathetic preganglionic neurons of(More)
RATIONALE Regulator of G-protein signaling 5 (RGS5) modulates G-protein-coupled receptor signaling and is prominently expressed in arterial smooth muscle cells. Our group first reported that RGS5 is important in vascular remodeling during tumor angiogenesis. We hypothesized that RGS5 may play an important role in vessel wall remodeling and blood pressure(More)
Preeclampsia is a systemic vascular disorder of pregnancy and is associated with increased sensitivity to angiotensin II (AngII) and hypertension. The cause of preeclampsia remains unknown. We identified the role of regulator of G protein (heterotrimeric guanine nucleotide-binding protein) signaling 5 (RGS5) in blood pressure regulation during pregnancy and(More)
AIM AND METHODS Haemorrhage is characterized by two distinct responses, sympathoexcitation that evokes tachycardia and supports blood pressure, followed by sympathoinhibition contributing to bradycardia and hypotension. It has been shown that anaesthetics alter the response to haemorrhage and we hypothesized that rat strain may also influence the response.(More)
Intrapericardial injections have been proposed as a means to specifically treat diseases of the myocardium, pericardium, and coronary vasculature. The pericardial space is potential drug reservoir, allowing sustained delivery of drug to the target tissue. In this study we have demonstrated a novel method for pericardial delivery in the mouse.
Cardiovascular disease [CVD] is the top cause of death in Australian women. Large studies in the US and Europe have shown that the majority of women do not consider CVD as their greatest health threat. Australian women's awareness has not previously been investigated. The aim of this cross-sectional survey [TAWDAH] was to assess Australian women's awareness(More)
