Chemical Strategies for Multistimuli Responsive Dynamic Covalent Materials in Regenerative Medicine

Advanced Healthcare Materials, EarlyView.
Multistimuli responsive dynamic covalent materials integrate reversible chemistry with the complex chemical, mechanical, and biochemical cues of regenerative environments. This review highlights chemical strategies based on orthogonal dynamic bonds, multicomponent networks, and hierarchical architectures to regulate mechanics, degradation, and ...

History of the J Wave and J Wave Syndromes

2016
Since discovery of the Brugada syndrome, ECG phenomena of late ventricular depolarization and early ventricular repolarization has rapidly gained recognition as a major cause of life-threatening arrhythmias, and dramatically accelerated a series of remarkably insightful discoveries in experimental, genetic, and clinical cardiac electrophysiology.

Electrocardiographic J wave of hypercalcemia

The American Journal of Cardiology, 1984
In 1920, Krausl reported electrocardiographic changes in experimental animals with hypercalcemia; we believe that his Figure 1 showed an ST-junctional deflection resembling the J wave of hypothermia. Except for a 1922 article by the same author, we have found no further reports that suggest J waves in hypercalcemia in either experimental animals or ...

The genetics of the J wave patterns

Journal of Electrocardiology, 2013
The rapid growth of medical genetics over the past few decades has transformed the way we think about the fundamental properties of cardiac conduction. Recent studies have demonstrated associations of gene variants and complex traits such as QT and PR interval.

J-wave syndrome(s)

Trends in Cardiovascular Medicine, 2015
The recognition of an overlap in clinical features between the Brugada syndrome and idiopathic ventricular fibrillation (VF) with inferolateral J-point elevation has raised the hypothesis that they are caused by a single pathophysiological mechanism. Indeed, even a term has been proposed to cluster these conditions: “J-wave syndromes” [1].

The J wave in accidental hypothermia

Journal of Electrocardiology, 1983
Electrocardiograms of 50 patients with accidental hypothermia were reviewed with regard to the J wave with the following results: (1) J waves were observed in 40 of 50 cases. (2) J waves were recorded most frequently in leads II or V6 (34 of 40 cases, 85%). However, in deep hypothermia, the J wave was often most prominent in leads V3 or V4.

Challenging case of J-wave syndromes

Heart, 2020
A 42-year-old man presented after accidental drug overdose complicated by out-of-hospital cardiac arrest. The patient underwent cardiopulmonary resuscitation with successful return of spontaneous circulation and was admitted to the intensive care unit for postcardiac arrest care, which included targeted temperature management (TTM).

Cellular Basis for the Electrocardiographic J Wave

Circulation, 1996
Background The J wave is a deflection that appears in the ECG as a late delta wave following the QRS or as a small secondary R wave (R′). Also referred to as an Osborn wave, the J wave has been observed in the ECG of animals and humans for more than four decades, yet the mechanism underlying its manifestation is poorly ...
