Bachmann's Bundle‐Related Atrial Tachycardias Following Catheter Ablation of Persistent Atrial Fibrillation

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background Atrial tachycardias (AT) after radiofrequency ablation (RFA) of atrial fibrillation (AF) may utilize Bachmann's bundle (BB). Due to their epicardial location, these ATs remain poorly understood. Objective To describe the electrophysiologic and anatomic basis of BB‐related ATs.

Body size of male Atlantic salmon (Salmo salar L.) at introduction of a 5‐week LD12:12 winter signal influences their decision to mature early or smoltify

open access: yesJournal of Fish Biology, EarlyView.
Abstract Sexual maturation of male Atlantic salmon post‐smolts (‘jacking’) is undesired in aquaculture and seems to occur due to the intensification in modern facilities. Maturation depends on internal and external factors (temperature, photoperiod, feed availability, energy levels, body size, genetic background) that act on the brain‐pituitary‐gonad ...

Period of the day drives distinctions in the taxonomic and functional structures of reef fish assemblages

open access: yesJournal of Fish Biology, EarlyView.
Abstract Circadian processes are key drivers of animal behaviour, influencing patterns of activity, resource partitioning and competition avoidance. Studies evaluating circadian changes on the structure of marine assemblages are lacking, especially for reef fish.

Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

open access: yesJournal of Anatomy, EarlyView.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...

The Ecology of Human Sleep (EcoSleep) Cohort Study: Protocol for a longitudinal repeated measurement burst design study to assess the relationship between sleep determinants and outcomes under real‐world conditions across time of year

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The interplay of daily life factors, including mood, physical activity, or light exposure, influences sleep architecture and quality. Laboratory‐based studies often isolate these determinants to establish causality, thereby sacrificing ecological validity.
