A Touch Enabled Hemodynamic and Metabolic Monitor

Advanced Science, EarlyView.
This work presents a touch‐based hybrid platform for simultaneous monitoring of vital signs and sweat metabolites. With a simple tri‐finger touch of 4–6 min, users can concurrently get to know their glucose, uric acid, cortisol levels from fingertip sweat, along with blood pressure and heart rate.

Pattern of initiation of monomorphic ventricular tachycardia in recorded intracardiac electrograms [PDF]

, 2005
Background: By analyzing stored intracardiac electrograms during spontaneous monomorphic ventricular tachycardia (VT), we examined the patterns of the VT initiation in a group of patients with implantable cardioverter defibrillators (ICDs).

Cardiac Slc25a49‐Mediated Energy Reprogramming Governs Doxorubicin‐Induced Cardiomyopathy through the G6P–AP‐1–Sln Axis

Advanced Science, EarlyView.
Doxorubicin‐induced cardiomyopathy involves mitochondrial energy metabolism dysfunction, exacerbated by cardiomyocyte‐specific Slc25a49 deficiency via oxidative phosphorylation (OXPHOS) suppression and glycolysis activation. The Slc25a49–glucose‐6‐phosphate (G6P)–activator protein‐1 (AP‐1) axis drives myocardial injury by upregulating Sln, disrupting ...

Relating the spectrum of cardiac signals to the spatiotemporal dynamics of cardiac sources [PDF]

arXiv, 2013
An increasing number of studies use the spectrum of cardiac signals for analyzing the spatiotemporal dynamics of complex cardiac arrhythmias. However, the relationship between the spectrum of cardiac signals and the spatiotemporal dynamics of the underlying cardiac sources remains to date unclear.

High‐Throughput MicroED for Probing Ion Channel Dynamics

Advanced Science, EarlyView.
High‐throughput MicroED offers a new approach for visualizing ion channel dynamics. This approach reveals NaK’s sodium binding modes and NaK2CNG’s potassium‐induced selectivity filter dilation and gating. By capturing these distinct structures, this work challenges traditional models of ion channel permeation and selectivity. Abstract Ion channels play

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]

, 2012
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...
