Pathophysiological Mechanisms of Premature Ventricular Complexes [PDF]

, 2020
Premature ventricular complexes (PVCs) are the most common ventricular arrhythmia. Despite the high prevalence, the cause of PVCs remains elusive in most patients.

Damage‐Free Passivation of Ambipolar OECTs with Fluoropolymer Film for Enhanced Performance and Stability Toward Reliable Biosignal Processing

Advanced Science, EarlyView.
A damage‐free iCVD fluoropolymer passivation strategy is introduced for ambipolar vertical OECTs. Vapor‐phase infiltration and thermal annealing induce nanoscale phase separation in the OMIEC channel, enhancing overall device performance. A single‐channel bipolar event‐driven spiking encoder is also demonstrated for electrocardiogram signal encoding ...

Heart rate turbulence in patients with stable coronary artery disease and its relationship with the severity of the disease

Türk Kardiyoloji Derneği Arşivi, 2015
OBJECTIVE: Heart rate turbulence (HRT) indicates the impairment of cardiac autonomic function. With the literature containing insufficient information on HRT in stable coronary artery disease (CAD), this study aimed to investigate the role of HRT in ...

Intrasplenic Thymus Organogenesis from Injectable Tissue Fragments Restores Functional T‐Cell Immunity

Advanced Science, EarlyView.
Clinical intramuscular thymus transplantation yields only short‐lived efficacy and marginal therapeutic benefits. Benefiting from the spleen's intrinsic strengths—rapid vascular perfusion, abundant developmental factors, and resident progenitors—the intrasplenic thymic grafts achieve robust thymic regeneration and substantial T‐cell reconstitution ...

Prognostic significance of premature ventricular complex burden on hospitalized patients with heart failure

Journal of Arrhythmia, 2020
Background The clinical significance of premature ventricular complexes (PVCs) in heart failure (HF) remains unclear. We aimed to clarify the associations of PVC burden with re‐hospitalization and cardiac death in HF patients.

Dissecting the roles of mTORC1 and mTORC2 in the mouse heart [PDF]

, 2013
Mammalian target of rapamycin (mTOR) is an evolutionary conserved serine/threonine kinase that regulates cell growth and metabolism. mTOR occurs in cells in two complexes, termed mTORC1 and mTORC2.

Increased Disarray of Extracellular Matrix Collagen‐I Fiber Network and Compromised Biomechanics in Aortae From Marfan‐Syndrome Mice Assessed Through Combined Opto‐Biomechatronics

Advanced Science, EarlyView.
Combined structure‐function assessment in aortic rings from Marfan mice using MechaMorph Opto‐Biomechatronics technology relates increased elasticity (stiffness) and dynamic viscosity and less ordered extracellular matrix 3D‐structure (collagen) as potential causes for impaired Windkessel function and compromised haemodynamics in Marfan's syndrome ...
