A cardiac emergency in SPECT/CT and PET/CT occurs infrequently but necessitates prompt recognition and an appropriate ...

Am J Health Syst Pharm. 2011;68(1):21-35. The Prospective Randomized Evaluation of Cardiac Ectopy with Dobutamine or Natrecor Therapy (PRECEDENT) was a multicenter, randomized, open-label ...

In a surprising discovery, scientists have found that the heart possesses 'sweet taste' receptors, similar to those on our tongues, and that stimulating these receptors with sweet substances can ...

Summary: New research sheds light on how ketamine affects the brain by targeting a specific NMDA receptor subtype, GluN1-2B-2D. Scientists used electron cryo-microscopy to capture how ketamine binds ...

The ∼45 olfactory neuron classes in Drosophila express different odorant receptors, which determine the range of odorants that the neurons sense. Axons from each class of olfactory neurons project to ...

However, the way in which heart rate and inotropy affect turbulent flow has not been investigated. In this study we hypothesized that dobutamine stress would result in higher turbulence intensity in ...

Increased adrenergic tone resulting from cardiovascular stress leads to development of heart failure, in part, through chronic stimulation of β1 adrenergic receptors (βARs) on cardiac myocytes.

The second is the hemodynamic response to dobutamine. According to the Gorlin formula, both AVA and mean gradient may be low in the setting of low transvalvular flow rate. Therefore, it seems prudent ...

When cardiac output remains severely reduced with vasoconstriction despite increasing doses of dobutamine, the addition of milrinone may bypass the β-receptors that become downregulated by chronic ...
