Deep Learning Improves Robustness of Voxelwise Kinetic Modeling for Hyperpolarized Carbon‐13 MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate whether deep learning improves the robustness of voxelwise kinetic parameter estimation from hyperpolarized (HP) 13C MRI compared with nonlinear least‐squares (NLLS) fitting. Methods A hybrid neural network (NN) was trained on synthetic pyruvate/lactate time courses generated from an open‐system two‐compartment HP 13C ...

Electrocardiographic Tpeak-Tend interval and risk of cardiovascular morbidity and mortality:results from the Copenhagen ECG study

, 2016
BACKGROUND: The electrocardiographic Tpeak-Tend interval is considered a novel risk marker of cardiac arrhythmias and cardiovascular death, however, results have so far been conflicting.OBJECTIVE: We aimed to investigate the association between this ...

Evaluation of QT dispersion and T-peak to T-end interval in patients with early-stage sarcoidosis

Revista Portuguesa de Cardiologia, 2017
Introduction and Aim: Sarcoidosis increases inhomogeneity in ventricular repolarization due to the presence of sarcoid granuloma, which significantly correlates with ventricular fibrillation. Various studies have suggested that the interval from the peak

Signal detection and characterisation of a novel drug–drug interaction between methadone and a synthetic cannabinoid receptor agonist

British Journal of Pharmacology, EarlyView.
Background and Purpose Little is known about how synthetic cannabinoid receptor agonist (SCRA) co‐use with other psychoactive substances may exacerbate risk of death. This study aimed to characterise the polypharmacy of deaths where SCRAs were detected at post‐mortem, investigate the cardiotoxicity of SCRAs and probe their inhibition of human ether‐a ...

Torsade de pointes induced by intravenous amiodarone therapy accompanied by marked augmentation of the transmural dispersion of repolarization in a patient with tachycardia‐induced‐cardiomyopathy

Annals of Noninvasive Electrocardiology, 2021
We report a 77‐year‐old human on renal dialysis for end‐stage renal disease with heart failure and atrial fibrillation (AF) complicated by a high ventricular frequency. The underlying disease was thought as tachycardia‐induced‐cardiomyopathy. Intravenous

Persistent in vitro nociceptor hyperexcitability and axonal retraction produced by repeated paclitaxel doses

The FEBS Journal, EarlyView.
Repeated paclitaxel exposure causes long‐lasting nociceptor hyperexcitability and axonal retraction in adult sensory neurons. Using a long‐term primary nociceptor culture, we show that hyperexcitability is mediated by sequential upregulation of NaV1.8, TRPV1, TRPA1, and TRPM8 channels.

Evaluation of Electrocardiographic T-peak to T-end Interval in Subjects with Increased Epicardial Fat Tissue Thickness

Arquivos Brasileiros de Cardiologia, 2015
Background:The association between periatrial adiposity and atrial arrhythmias has been shown in previous studies. However, there are not enough available data on the association between epicardial fat tissue (EFT) thickness and parameters of ventricular

Arctic lake trout (Salvelinus namaycush) show evidence of seasonal acclimation of cardiac adrenergic sensitivity but not heat tolerance

Journal of Fish Biology, EarlyView.
Abstract Many Arctic fishes experience prolonged periods of extreme cold and large thermal variation over both rapid and seasonal time scales which challenge critical physiological functions. In the central Canadian Arctic, we caught wild adult lake trout (Salvelinus namaycush) acclimatized to winter and summer temperatures to determine the extent to ...
