Stretch‐Induced Increase in Cardiac Contractility Is Independent of Myocyte Ca\u3csup\u3e2+\u3c/sup\u3e While Block of Stretch Channels by Streptomycin Improves Contractility After Ischemic Stunning [PDF]
, 2015 Stretching the cardiac left ventricle (LV) enhances contractility but its effect on myoplasmic [Ca2+] is controversial. We measured LV pressure (LVP) and [Ca2+] as a function of intra-LV stretch in guinea pig intact hearts before and after 15 min global ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Status epilepticus (SE) is associated with significant mortality. Sleep architecture may reflect normal brain function. Impaired sleep architecture is associated with poorer outcomes in numerous conditions. Here we investigate the association of sleep architecture in continuous EEG (cEEG) with survival in SE.

Effects of postconditioning with N,N,N'N'-tetrakis-[2-pyridylmethyl]-ethylenediamine in isolated rat hearts [PDF]
Korean Journal of Anesthesiology, 2010 BackgroundIt was reported that N,N,N'N'-tetrakis-[2-pyridylmethyl]-ethylenediamine (TPEN), a transition metal chelator, confers cardioprotection against myocardial ischemic injury.

Takotsubo cardiomyopathy after microwave ablation of hepatocellular carcinoma
Radiology Case Reports, 2023 Takotsubo cardiomyopathy is a form of stress cardiomyopathy that can clinically mimic an acute ST-segment elevation myocardial infarction (STEMI). It involves transient anomalies in left ventricular wall motion secondary to myocardial stunning.

Phosphorylation by protein kinase C and the responsiveness of Mg2+-ATPase to Ca2+ of myofibrils isolated from stunned and non-stunned porcine myocardinm [PDF]
, 1997 Previously we showed in an in situ porcine model that the thiadiazinone derivative [+]EMD 60263, a Ca2+ sensitizer without phosphodiesterase III inhibitory properties, increased contractility more profoundly in stunned than in non-stunned myocardium ...

Life‐Threatening Bradycardia in Anti‐NMDA‐Receptor Encephalitis and a Novel Use for Permanent Pacing
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Pediatric anti‐NMDA receptor encephalitis (pNMDARE) is an autoantibody‐mediated disorder that can cause severe autonomic dysfunction, including symptomatic bradycardia and asystole. Dysautonomia can last for years, making it very challenging to manage.

Endothelial Dysfunction and Vascular Preconditioning
Journal of Biological Research, 2003 The prolonged occlusion of a coronary artery followed by reperfusion causes deleterious effects known as “ischemiareperfusion injuries”. In fact, these injuries,which affect both myocardium and coronary endothelium, initiate during ischemia and worsen ...

Myocardial dysfunction after out-of-hospital cardiac arrest: predictors and prognostic implications. [PDF]
, 2018 We aim to determine the incidence of early myocardial dysfunction after out-of-hospital cardiac arrest, risk factors associated with its development, and association with outcome.
