Optimizing the predictive validity of NIRS kinetic profiles to predict aerobic capacity from a resting skeletal muscle occlusion test

Experimental Physiology, Volume 111, Issue 3, Page 738-750, 1 March 2026.
Abstract Measuring and monitoring individual cardiorespiratory fitness through a valid and accessible non‐exhaustive surrogate is required. Techniques measuring haemodynamics have shown promise, and this study aimed to optimize the predictive validity of these approaches alongside developing predictive equations.

Effects of moxifloxacin on the proarrhythmic surrogate markers in healthy Filipino subjects: Exposure-response modeling using ECG data of thorough QT/QTc study

Journal of Pharmacological Sciences, 2018
Effects of moxifloxacin on QTc as well as proarrhythmic surrogate markers including J-Tpeakc, Tpeak-Tend and short-term variability (STV) of repolarization were examined by using both standard E14 time-based evaluation and exposure-response modeling. The

Suppression of premature ventricular complexes with the PDE5 inhibitor sildenafil: First clinical experience

Experimental Physiology, Volume 111, Issue 3, Page 625-631, 1 March 2026.
Abstract The phosphodiesterase‐5 inhibitor sildenafil suppresses ventricular arrhythmias in a sheep model of drug‐induced long QT. In that study, ventricular arrhythmias were abolished by reducing premature ventricular complexes (PVCs) and delaying PVC onset, thus preventing ‘R‐on‐T’ ventricular tachycardia.

Contemporary Perspectives on J‐Wave Syndromes: An Expert Consensus Statement

Journal of Arrhythmia, Volume 42, Issue 1, February 2026.
ABSTRACT J‐wave syndromes (JWS)—comprising Brugada syndrome (BrS) and early repolarization syndrome (ERS)—are important causes of malignant ventricular arrhythmias and sudden cardiac death in patients whose hearts appear structurally normal. Since the 2016 consensus, advances in genetics, pathophysiology, and therapy have redefined both understanding ...

Electrocardiographic markers of proarrhythmogenicity in metabolic syndrome [PDF]

Българска кардиология
The etiopathogenetic mechanisms of metabolic syndrome that affect cardiac electrophysiology and lead to myocardial remodelling are numerous. Cardiomyocyte changes induced by metabolic and proinflammatory factors impair repolarization, exacerbate the ...

Microencapsulation of Saccharomyces boulardii in Prebiotic‐Enriched Matrices: A Strategy for Probiotic Viability Enhancement Using Sugarcane Juice

Journal of Food Process Engineering, Volume 49, Issue 2, February 2026.
Spray drying Saccharomyces boulardii with sugarcane juice, inulin and maltodextrin produced microcapsules with enhanced viability, reduced moisture loss, and enhanced thermal stability. This synergistic matrix offers a promising strategy for developing stable and functional probiotic delivery systems.

Temporal Variability in Electrocardiographic Indices in Subjects With Brugada Patterns

Frontiers in Physiology, 2020
IntroductionPatients with Brugada electrocardiographic (ECG) patterns have differing levels of arrhythmic risk. We hypothesized that temporal variations in certain ECG markers may provide additional value for risk stratification.
