Dispersión del intervalo QT: un predictor de arritmias ventriculares malignas. Dispersion of the QT intervals: a predictor of malignat ventricular arrhytmias.

Revista Cubana de Cardiología y Cirugía Cardiovascular, 2000
El intervalo QT es un marcador del estado de la repolarización ventricular. El aumento de la heterogeneidad en la repolarización de los ventrículos, se asocia a un mayor riesgo para la aparición de arritmias ventriculares malignas y puede ser expresado a

QT Dispersion and T-Wave Alternans of Early Repolarization Electrocardiogram

Majalah Kardiologi Indonesia, 2013
Background. It has been well known that early repolarization is only normal ECG variant without significant clinical consequences. However, recent studies show variable results of its relation to ventricular arrhythmias occurence.

Bioinspired Metastable Transient Peeling for Repeatable Rapid Release

Advanced Science, EarlyView.
Inspired by the explosive seed ejection of the squirting cucumber, this work introduces metastable transient peeling that temporally regulates stored interfacial energy release via a tunable energy barrier. A viscoelastic hemispherical gripper achieves 52 ms ultrafast, residue‐free release with 300 000‐cycle durability, enabling damage‐free handling of

Ilexoside K Ameliorates Atherosclerosis by Suppressing CD72hi Macrophages and Blocking CXCL12–CXCR4 Axis to Inhibit Endothelial Pyroptosis

Advanced Science, EarlyView.
CD72hi macrophages drive endothelial pyroptosis and accelerate atherosclerosis through CXCL12–CXCR4‐mediated immune–vascular crosstalk. Ilexoside K suppresses this pathogenic communication by modulating CXCR4‐dependent endothelial responses, reducing inflammation and plaque progression. These findings reveal a macrophage–endothelial regulatory axis and

TACHY-DEPENDENT DISPERSION OF QT INTERVAL AND INTRAVENTRICULAR CONDUCTIVITY DISTURBANCES: CLINICOINSTRUMENTAL PARALLELS

Российский кардиологический журнал, 2010
In 28 patients with intraventricular block and coronary heart disease (CHD), as well as in 20 professional ex-athletes with impaired intraventricular conductivity, corrected QT interval dispersion at maximal and minimal heart rate (HR) was assessed ...

Age‐Related Lamin B1 Deficiency Activates SLC7A11‐Dependent Disulfidptosis to Impair Osteogenesis via Intercepting Mitochondrial Fission

Advanced Science, EarlyView.
This study reveals that age‐related LMNB1 deficiency in mesenchymal stem cells epigenetically upregulates SLC7A11, triggering actin disulfidptosis and mitochondrial dysfunction. This cascade impairs bone formation in senile osteoporosis. Furthermore, researchers identified the FDA‐approved drug naldemedine as a targeted SLC7A11 inhibitor to reverse ...

The effect of esmolol on corrected-QT interval, corrected-QT interval dispersion changes seen during anesthesia induction in hypertensive patients taking an angiotensin-converting enzyme inhibitor

Revista Brasileira de Anestesiologia, 2015
BACKGROUND AND OBJECTIVES: The importance of minimizing the exaggerated sympatho-adrenergic responses and QT interval and QT interval dispersion changes that may develop due to laryngoscopy and tracheal

A Novel Reactive Oxygen Species‐Responsive Bone‐Targeted Nanoplatform Based on Cloperastine Attenuates Ovariectomy‐Induced Bone Loss by Inhibiting Osteoclast Oxidative Phosphorylation

Advanced Science, EarlyView.
Cloperastine suppresses osteoclastogenesis by inhibiting PGC1β‐mediated oxidative phosphorylation. Its incorporation into a ROS‐responsive, Asp8‐modified nanoplatform enhances skeletal accumulation. The resulting Clo/Asp8‐PMK‐MCs combine cloperastine‐mediated antiresorptive activity with carrier‐mediated osteogenic activity to attenuate OVX‐induced ...

Evolution of Physical Intelligence Across Scales

Advanced Intelligent Discovery, EarlyView.
By following the evolution of physical intelligence across scales, this article shows how intelligence arises from materials, structures, physical interactions, and collectives. It establishes physical intelligence as the evolutionary foundation upon which embodied intelligence is built.

QT Dispersion: Does It Change after Percutaneous Coronary Intervention? [PDF]

Journal of Tehran University Heart Center, 2011
Background: Myocardial ischemia is one of several causes of prolonged QT dispersion. The aim of this study was to evaluate the effect that percutaneous coronary intervention has on the depolarization and repolarization parameters of surface ...
