Article Abstract
Objective: The potential risk of inducing ventricular arrhythmias was explored by employing pulsed field ablation (PFA) through the administration of both monophasic and biphasic waveform deliveries.
Methods: PFA was applied to specific locations in the right ventricle (RV, n = 5 sites) in swine (n = 2), utilizing identical settings with consistent amplitude, pulse width, and a number of pulses for both monophasic and biphasic waveforms. PFA deliveries were precisely timed in 10-ms intervals across the entire T wave.
Results: Using monophasic waveforms, ventricular fibrillation (VF) was induced 7/7 times when PFA pulses were delivered during the T wave. Biphasic waveforms resulted in no ventricular arrhythmias when PFA was delivered across the entire duration of T wave.
Conclusions: Our findings indicate that VF can be consistently induced with monophasic pulse waveforms, but not with biphasic pulse waveforms in a porcine model.

Hemolysis, myocardial and neural injury after monopolar pulsed field ablation using a novel lattice-tip catheter to treat atrial fibrillation.

Background And Aims: Aim of this study was to assess the risk of hemolysis, the extent of myocardial and neural injury after monopolar, monophasic pulsed field ablation (PFA) using a lattice-tip catheter in comparison to single-shot PF ablation platforms employing bipolar, biphasic waveforms.
Methods: This prospective study included consecutive patients undergoing PFA for atrial fibrillation (AF) using the Affera™ mapping and ablation system (n=40). Biomarkers for hemolysis (haptoglobin, LDH, bilirubin), myocardial injury (high-sensitive troponin T, CK, CK-MB), neurocardiac injury (S100), and renal function (creatinine) were assessed pre- and within 24 hours post-ablation.

As our understanding of sleep evolves, a recurring recommendation remains that adults should sleep in a single, uninterrupted nocturnal bout - commonly referred to as monophasic sleep. However, the scientific foundation for this standard may be less canonical than previously assumed, particularly when considering individual variability in sleep needs and organization. Historical texts and recent research suggest an alternative view: that sleep can be naturally segmented into two periods across the 24h cycle - a pattern known as biphasic sleep.

Context: The shape of glucose response in the oral glucose tolerance test (OGTT) is a biomarker for pancreatic β-cell health. A biphasic response is deemed metabolically healthier compared to monophasic, while persistent increase is a harbinger of diabetes.
Objective: To assess the relationship of inflammatory markers with the shape of glucose OGTT response in a wide age range and populations.
Comparative Decay Dynamics and Detectability of eDNA and eRNA in Connected and Isolated Freshwater Mesocosms Using Digital PCR.

Efficient use of environmental nucleic acids (eNAs) in freshwater biodiversity monitoring requires understanding their degradation and detectability in interconnected ecosystems. We employed a novel field-scale assay to compare environmental DNA (eDNA) and environmental RNA (eRNA) decay rates and detectability across four genetic markers (16S, 18S, COI and LDHA) in connected and isolated 1000-L mesocosms containing natural planktonic assemblages. This design provides ecologically relevant and complex settings to assess how connectivity influences the detectability of eNA over time.

Biomolecular condensates regulate cellular biochemistry by organizing enzymes, substrates and metabolites, and often acquire partially de-mixed states whereby distinct internal domains play functional roles. Despite their physiological relevance, questions remain about the principles underpinning the emergence of multi-phase condensates. Here, a model system of synthetic DNA nanostructures able to form monophasic or biphasic condensates is presented.
