When the clock strikes: Modeling the relation between circadian rhythms and cardiac arrhythmias [PDF]

arXiv, 2016
It has recently been observed that the occurrence of sudden cardiac death has a close statistical relationship with the time of day, viz., ventricular fibrillation is most likely to occur between 12 am-6 am, with 6 pm-12 am being the next most likely period.

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.

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 ...

The clinical effect of arrhythmia monitoring after myocardial infarction (BIO-GUARD|MI):study protocol for a randomized controlled trial

Trials, 2019
Background The increasing use of implantable cardiac monitors (ICMs) allows early documentation of asymptomatic cardiac arrhythmias that would previously have gone unnoticed.

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.

A Phase II Trial of Geriatric Assessment‐Guided Selection of Treatment Intensity in Older Adults With AML

American Journal of Hematology, EarlyView.
ABSTRACT How to select the appropriate intensity of chemotherapy in older adults with acute myeloid leukemia (AML) remains an unanswered question. In a phase II trial of older adults ≥ 60 years with AML (n = 73), we used geriatric assessment (measures of comorbidity burden, physical and cognitive function) to determine fitness for intensive ...

Comparison of Cardiac Arrhythmias between Late Pregnancy and Early Post-partum Periods in Clinically Healthy Iranian Fat-Tailed Sheep [PDF]

Pakistan Veterinary Journal, 2011
The current study was conducted to find out the prevalence of cardiac arrhythmias in clinically healthy Iranian fat-tailed sheep in two physiological states, i.e., late pregnancy and early post-partum periods.

Magnetic Signature of Thermo-Electric Cardiac Dynamics [PDF]

Physical Review E, 111, 2025, L012401
Developing new methods for predicting electromagnetic instabilities in cardiac activity is of primary importance. However, we still need a comprehensive view of the heart's magnetic activity at the tissue scale. To fill this gap, we present a model of soft active matter, including thermo-electric coupling, suitably modified to reproduce cardiac ...

In vivo toxic and lethal cardiorespiratory effects of a synthetic quaternary ammonium salt derivative of haloperidol in mice

Animal Models and Experimental Medicine, EarlyView.
Hematoxylin–eosin (H&E) stains of the heart, liver, lung, and kidney show acute toxicity. Abstract Background To investigate the toxicity of N‐n‐butyl haloperidol iodide (F2), a quaternary ammonium salt derivative of haloperidol, in mice for potential therapeutic purposes. Methods The acute median lethal dose (LD50) of F2 was determined using the Bliss
