Metabolic changes during cardiac regeneration in the axolotl

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The axolotl is a prominent model organism of heart regeneration due to its ability to anatomically and functionally repair the heart after an injury that mimics human myocardial infarction. In humans, such an injury leads to permanent scarring. Cardiac regeneration has been linked to metabolism and the oxygenation state, but so far,

Sudden cardiac death in children and adolescents (excluding Sudden Infant Death Syndrome)

open access: yesAnnals of Pediatric Cardiology, 2010
Sudden death in the young is rare. About 25% of cases occur during sports. Most young people with sudden cardiac death (SCD) have underlying heart disease, with hypertrophic cardiomyopathy and coronary artery anomalies being commonest in most ...

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

open access: yesEcography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...

Surface Properties of Electrode Materials: A Key Factor Affecting the Catalytic Activity of Redox Mediators in Li–O2 Battery Discharge

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work investigates how the surface properties of oxygen cathodes influence the catalytic performance of redox mediators in Li–O2 batteries. The results conclusively demonstrate that electrodes with more surface defects promote parasitic reactions and lead to the accumulation of insulating discharge products, severely impairing electron transfer and
