Phospholamban: a tiny protein with a prominent role in the regulation of cardiac relaxation and contractility
(SAFIS, 2010-11)
Phospholamban (PLN) is a small sarcoplasmic reticulum (SR) protein that in the dephosphorylated state tonically inhibits the SR Ca2+-ATPase (SERCA2a). Different type of evidence to be described, points to PLN as a crucial ...
Is there nascent structure in the intrinsically disordered region of troponin I?

Maximum likelihood estimation of cardiac fiber bundle orientation from arbitrarily spaced diffusion weighted images
(Elsevier, 2017)
We propose an estimation scheme for local fiber bundle direction in the left ventricle directly from gray values of arbitrarily spaced cardiac diffusion weighted images (DWI). The approach is based on a parametric and ...
Therapeutical intervention, relaxation, mental images, and spirituality (RIME) for spiritual pain in terminal patients. A training program

Sildenafil preserves diastolic relaxation after reduction by L-NAME and increases phosphodiesterase-5 in the intercalated discs of cardiac myocytes and arterioles
(Faculdade de Medicina / USP, 2011)
OBJECTIVES: We investigated the influence of sildenafil on cardiac contractility and diastolic relaxation and examined the distribution of phosphodiesterase-5 in the hearts of hypertensive rats that were treated with by ...
Exercise-QTc is associated with diffuse interstitial fibrosis reflected by lower approximated T1 relaxation time in hypertrophic cardiomyopathy patients
(Elsevier, 2017)
Hypertrophic cardiomyopathy (HCM) is frequently associated with exercise-related sudden death. One possible contributor to arrhythmias is pathologic hypertrophy, which can lead to QTc prolongation. Since beta-adrenergic ...
How drugs modulate the performance of the human heart
(2022)
Many drugs interact with ion channels in the cells of our heart and trigger heart rhythm disorders with potentially fatal consequences. Computational modeling can provide mechanistic insight into the onset and propagation ...
