Phosphodiesterase 5 (PDE5) inhibitors limit myocardial injury caused by stresses, including doxorubicin chemotherapy. cGMP binding to PKG I ? attenuates oxidant-induced disulfide formation. Because PDE5 inhibition elevates cGMP and pro- tects from …

Cardiovascular disease (CVD) is the leading cause of the death worldwide. An increasing number of studies have found that autophagy is involved in the progression or prevention of CVD. However, the precise mechanism of autophagy in CVD, especially the …

Excessive cardiac interstitial fibrosis impairs normal cardiac function. We have shown that the α11β1 (α11) integrin mediates fibrotic responses to glycated collagen in rat myocardium by a pathway involving transforming growth factor-β. Little is known of …

Hyperaldosteronism is associated with an increased prevalence of atrial fibrillation (AF).Mutations in KCNE3 have been associated with AF, and Kcne32/2 mice exhibit hyperaldosteronism. In this study, we used recently developed Kcne32/2 mice to study …

Abstract Bolus injections of adenosine and the A2A adenosine receptor (AR) selective agonist (regadenoson) are used clinically as a substitute for a stress test in people who cannot exercise. Using isolated tissue preparations, our lab has shown that …

Aims: Cardiac angiogenesis is an important determinant of heart failure.We examined the hypothesis that protein tyrosine phosphatase (PTP)-1B, a negative regulator of vascular endothelial growth factor (VEGF) receptor-2 activation, is caus- ally involved …

The irreversible loss of cardiomyocytes due to oxidative stress is the main cause of heart dysfunction following ischemia/reperfu- sion (I/R) injury and ageing-induced cardiomyopathy. Here, we report that CUEDC2, a CUE domain-containing protein, plays a …

There is accumulating evidence during sepsis that cardiomyocyte (CM) homeostasis is compromised, resulting in cardiac dysfunc- tion. An important role for complement in these outcomes is now demonstrated. Addition of C5a to electrically paced CMs caused …

Photoacoustic imaging (PAI) is an emerging tool that bridges the traditional depth limits of ballistic optical imaging and the resolution limits of diffuse optical imaging. Using the acoustic waves generated in response to the absorption of pulsed laser …

In humans, the increased cardiovascular demands of pregnancy are met by increases in cardiac output (CO), stroke volume (SV), plasma volume (PV), and cardiac and aortic inner dimensions and a concurrent decrease in arterial pressure that indicates a fall …
